Summary of operation and maintenance mode Article 1 During this month's work, the operation and maintenance service was normal and all computer equipment was in good condition. Ensure the quality of service and improve the satisfaction of all departments with IT operation and maintenance this month. Be responsible for the work, work hard, abide by the law, obey the management, reflect self-worth, and provide better service for xxx. The following is a summary analysis and description of all failures in June.
1, IT operation and maintenance service ***49 times
In this month's IT operation and maintenance service, the statistics are as follows:
Office system failure: 6 times, attendance: 2 times, printer/copier: 9 times, computer failure: 9 times, Zhongpu data: 8 times, other failures: 15 times.
2. Maintenance and consumables
(The above does not include photocopier consumables and consumables)
The total cost of adding printing consumables for six times in May was 2660 yuan, the total cost of hardware maintenance for two times in May was 3 130 yuan, and the total cost of adding printing consumables for one time in June was 1 80 yuan.
3. Description and explanation of 3.IT operation and maintenance services
First, take stock of computer assets and rationally allocate computer resources.
Combined with the inventory of computer assets made in May, computers with expired years were scrapped in the accounts. Since the contract was renewed in June, it is necessary to count all the computer equipment in the company and classify which equipment is under warranty and which is out of warranty. * * * Counting computer hosts: 125, monitors: 14 1, laptops: 6 1, printers: 55. Among them, there are 142 devices within the warranty period and 252 devices outside the warranty period. In April, our company newly purchased 30 computers (Tsinghua Tongfang) and 5 printers (OKI820B black and white). In order to ensure the daily office and xxxxxx demand of each department, xxxxxx department has added 5 printers, which are in good use at present. There are 38 computers that have reached the retirement age this year, and they will be replaced in the later period without affecting users' use.
Second, xxxxxx safety equipment increased
Before receiving this task, fortunately, I have some technical knowledge related to monitoring engineering. In order to strengthen monitoring, it is necessary to check the existing safety systems and equipment, as well as lines and pipelines. The specific difficulty lies in wiring, and other technical aspects are basically solved. There is not much technical content in this respect, and you can basically understand it with a little contact. The ceiling is high from the ground, and it is difficult to narrow the ceiling maintenance passage, which is completed by its engineering department. In terms of technology, I learned that the definition of the camera is determined by the number of lines. * * * bought three 600-line cameras, which are currently being used by the mainstream. In order to reduce the burden of wiring engineers, centralized power supply is adopted, that is, all cameras are powered on the same power supply 12V. That is, there is no need to pull wires from other places to connect the socket when wiring. Because all floors have centralized power supply, the power supply is somewhere on the floor. It is not the camera that determines the video quality, but the video recorder. VCR has several recording modes. Cif, 2cif, dcif, D 1, even higher. At present, there are four xxxxxx security devices, the video quality is all CIF, the resolution is 352x288, and the storage days are about 48 days, one of which is about 18 days.
Third, the maintenance of photocopiers and printer consumables.
In June, the printer consumables added 1 set of powder, and the copier changed the toner for five times. Printer: The overall performance is stable, basically zero failure for a whole month. Copier: The company responsible for maintenance pays a return visit every two weeks to clean up the parts of the copier, including the first-stage inspection and the replacement of the parts in the trial period. In the initial inspection section, the drum core must be replaced because of aging printing, which affects the printing effect. The total cost is 840 yuan. At present, the printing effect is good. The copier of the trial department damaged two parts, which were identified as man-made damage by the maintenance company. It may be that the side plate was closed too hard when the cardboard was taken out, which caused the hot drum hook and the double-sided guide plate to break and must be replaced. This part needs to be ordered by the manufacturer and reloaded in two weeks. The total cost is 2290 yuan. The status of the copier will be checked regularly to ensure its maximum performance. Fourth, the attendance rate
Attendance is an important learning opportunity. I will check whether all the tools are normal the day before I receive the attendance task. During an attendance at Ishii, the enterprise was an e-commerce enterprise with more than 0/00 employees/kloc, and the financial department was running several sets of system management software, just like the whole production line of the factory. Pre-sale, after-sale, delivery, return management, etc. There are more than 5 million data queried in the system, and it takes more than 30 minutes to export a data table. The server supported by such a large amount of data is not simple. There are 7 servers in the computer room, 4 of which are linux systems. Only when I got here did I find that I lacked knowledge, had little contact with linux system and forgot some commands. Besides, it was already off duty and the administrator was not there. Finally, it was not finished until after 8 o'clock. Although this job is hard, I have gained a lot and gained a lot of knowledge. At the same time, I also found my own shortcomings and will continue to study hard in the future. In addition to improving my technical level, it is more important to strengthen personnel exchanges.
Summary of operation and maintenance work mode Article 2 XXX post is technical operation and maintenance. The main work in the near future is:

The third chapter reviews some achievements made under the guidance of the leaders of the city and county work areas in the past year, but there are also some shortcomings. The operation is summarized as follows:
First, study hard new knowledge, master new equipment and improve business skills.
My unit is a substation that has just been built for 2 years. Office facilities and living utensils are complete, and I have the conditions to envy others' life and study. Since 20xx entered 1 10kV substation in April, under the care and guidance of the leaders of cities and counties, we have made great efforts to change the previous working modes and methods. From a self-attitude of doing one's own job well and having nothing to do with others, through continuous learning and exercise, it has gradually changed into a new collaborative office model that helps each other and completes and improves together. I remember that at the beginning of the station operation, I still learned the theory and operation method of equipment at sunrise and sunset every day. I am always in initial contact with 1 10 kV substation equipment, and I often feel invisible work pressure, which is eating me up, using the tone that the leaders of the city work area are worried about depression. And this also deeply inspired me to learn business knowledge more consciously.
Until one day last year, when I almost forgot all the business knowledge in my mind in the idea of trouble-free new equipment, I suddenly received the operation instruction of 1 10kV624 line for power outage maintenance. In the tone that the leaders of the city work area are still worried, I face it with correct accident handling methods and operation steps. After the default treatment, at the other end of the long telephone line, I seemed to see the leaders look slightly relaxed. ......
Second, based on this position, give play to party member's leading role.
As a grassroots substation party member, he is dedicated and loyal. In maintaining the purity of the Party and ideology, we can only love the Party, the country and the company by strengthening the cultivation of the awareness of safe operation of substations and the implementation of the established system management, serving the people well and promoting the all-round development of substation operation and maintenance. Over the past year, I have taken the initiative to study the party's principles and policies, strengthened the cultivation of party spirit, further improved my political consciousness and working ability, and played an exemplary role in performing my duties. Create a harmonious working atmosphere in the company's grass-roots sub-stations, be brave in taking responsibility, and fully reflect the excellent value of party member.
Under the new situation, many years of work in grass-roots substations have made me deeply understand the tasks faced by the company and the power grid development during the peak summer. From the challenge of the post, I always set an example everywhere, and fully reflected party member's execution and practice with practical actions. Over the past year, I have made clear the time period, place, personnel and work requirements, carried out temperature measurement and special inspection, including equipment overheating trip, line sag drop, etc., and comprehensively carried out state inspection and testing of substation equipment. Effectively prevent equipment accidents caused by inadequate inspection and maintenance of substation equipment. Through hard work and under the strong guidance of the leaders of the two work areas, the power supply work of "meeting the peak and spending the summer" has achieved satisfactory results and effects.
Third, carry forward the past and forge ahead into the future, and devote your enthusiasm to serving the people infinitely.
As an electric power worker, we should always focus on the cause of the party and enterprises; At all times, we should practice the core values of "honesty, responsibility, innovation and dedication" and perform the duties of state grid operators with high standards. In this year's "National Day" and "18th National Congress" of political power consumption, we strictly abide by various rules and regulations, strictly guard against death, and closely cooperate with power dispatching, effectively ensuring the normal listening and watching of local people's radio and television. I come from an ordinary worker in a grass-roots substation, and I must obey the overall interests and do my duty at all times. In this post, I will, as always, do my job well, be an honest official, give play to party member's exemplary leading role, strive to serve the local economic development, and hand in an answer sheet of "the organization is at ease and the people are satisfied" to the organization.
Summary of operation and maintenance work 4 I graduated from a university majoring in electrical engineering and automation in X month in xx year, joined a company in July in xx year, and transferred to a power plant in Huaneng in July in xx year. From work to now, I have participated in factory education, military training to internship in operation and maintenance department, and participated in equipment installation and tracking in a power plant. In this process, I learned a lot and made great gains and progress in many aspects. I have changed from a college student to a qualified employee of a large state-owned enterprise, and I have a deep understanding of my present job. The professional and technical situation in the past year is summarized as follows:
Security aspect
Preventing accidents and ensuring personal safety are the primary tasks of the power sector. In the process of repeatedly operating and maintaining the equipment with my master, I always adhere to the policy of "safety first, prevention first and comprehensive treatment", strictly implement the electric power safety work regulations, carefully analyze various difficulties in safety work, and formulate various safety measures consciously, purposefully and emphatically according to the characteristics of each task. In addition, the daily safety study organized by teams and groups should be carefully studied, and the safety accident cases should be carefully discussed and analyzed, so as to learn from them and prevent the recurrence of safety accidents.
Second, study and work.
1, the perfection of basic theory
In college, we learn more theories than objects and examples. The integration of theory with practice is not enough, and the theory is divorced from practice, which is not conducive to in-depth research. The so-called behind closed doors, without the guidance of practice, the theory will not be greatly improved. After coming to Jinghong power plant, the theoretical things in the past were guided by physical objects, which made the original vague concepts clear. Outstanding performance in the generator rotor, stator, water turbine, excitation system, speed control system, hydraulic structure and other structures have a deep perceptual knowledge.
2, the improvement of professional skills
During the operation, I followed the team leader to learn how to check the equipment, what to pay attention to during the inspection, and how to use the inspection instrument. Under the guidance of the masters, we slowly began to learn the objects to be monitored, the normal operation state of the equipment and how to judge and eliminate the faults of the unit. Every time we are on duty, our senior brothers should ask us questions, and try to learn a simple operation every eight hours. During the duty, it is necessary to make accident prediction, master the current situation of equipment in the whole plant and strengthen the monitoring of defective equipment.
In the process of being on call, we mainly learned how to write operation tickets and how to deal with various work tickets. When the unit was overhauled, we accompanied the master to do the safety measures for overhauling the unit, and learned how to restore the safety measures after overhaul. All these tasks need us to take them seriously and check them carefully. Only in this way can the safe and stable operation of the unit be guaranteed. During the operation, I participated in the start-stop operation of the unit for many times, and got a certain understanding of the start-stop process and matters needing attention.
During the maintenance period, under the guidance of the master, I learned to look at the electrical secondary diagram, understand the basic working principles of the excitation system and governor, and learn some basic principles and applications of the electrical controller and plc. During the overhaul of Unit 5, I mainly studied instrument knowledge with the master, and mastered the working principle and calibration method of measuring elements such as power transmitter, frequency transmitter, pressure gauge and digital display meter. And master the arrangement and setting value of main non-electric measuring points such as oil temperature, oil pressure, oil level and tile temperature in our factory. At the same time, I also mastered the use of some experimental equipment. In thermal instrumentation, understand the working principle and function of other sensors. In addition, I also participated in the maintenance of the governor of Unit 5. Through on-site study, I have a deeper understanding of the governor system and a systematic understanding of the things on the drawings.
In addition to maintenance tasks, we often work with the master to eliminate defects and deal with abnormal equipment. At work, the master often lets us assume that we are the person in charge of the work, how to deal with the problem, arouse our enthusiasm to solve the problem alone, and give us a lot of room for thinking. Through the teacher's inculcation, I summed up the matters that should be paid attention to when dealing with equipment failures: First, we should be familiar with the structure, principle and function of equipment in the system; Then, we can realize where the fault should be, how to deal with it, and what other equipment may be involved in the treatment; Only in this way can we judge what safety measures should be taken to avoid hurting ourselves and equipment.
Third, training and learning.
Since entering the power plant, the company has provided us with a good learning environment through various channels. From the initial induction training to the professional knowledge training arranged by the team every week and the monthly departmental examination training, when the factory representative came to assist in the work, the leaders also seized the opportunity to invite the factory technicians to tell us all kinds of professional knowledge, such as the training of plc basic knowledge and application, and the training of governor basic knowledge. In April of xx, the power plant also sent us to participate in the training of "Senior Duty Officer of Hydro-generator Unit Operation". In the process of continuous training, each of us has gained a lot. In addition to participating in various trainings organized by the collective, I also read some books on operation and maintenance of power plants in my spare time, such as Automation Device of Hydropower Plant, Operation Duty of Hydropower Station, Principle and Application of plc, and Relay Protection of Power System, which enriched my professional knowledge.
Fourth, the existing shortcomings and the direction of future efforts.
1, the theoretical knowledge of power plant production is not deep enough, because it is "operation and maintenance integration". Compared with the old production mode, we know a little more, but we haven't studied professional knowledge deeply enough. In the future, we should continue to strengthen the study of a certain professional knowledge and strive to achieve "one specialty and many functions" as soon as possible.
Multifunctional "requirements. Improve their comprehensive ability and keep up with the development needs of power plants.
2. In the usual work, although I participated in a lot of specific work, in view of the different division of labor during the maintenance period, my understanding of the whole system is still at the theoretical level, and my study of the system is still scattered, lacking a clear understanding of the whole, so I can't be independently responsible for the fault diagnosis and maintenance tasks of important and complex equipment. The improvement of this ability is also the main task of my future work and study.
Model essay summary of operation and maintenance work mode 5 I started to work as an operation and maintenance engineer in the system support department on xx, xx, xxxx. I have been working in the company for 3 months before I know it, and the probation period has passed. According to the company's rules and regulations, I now apply to become a full-time employee of the company. From the first day I came to the company, I integrated myself into our company and team. I deeply realized the positive atmosphere of the company and the great charm of all departments, and witnessed the gradual maturity of NOC. I saw the continuous improvement of the network and system in the company and the station, and it became clearer and clearer. At the same time, I also saw the learning platform and endless opportunities and challenges given by the operation and maintenance center to the operation and maintenance engineers. Therefore, I summarize my work in these three months as follows:
1. My job description: At work, I worked hard and won the recognition of department leaders and company colleagues. Of course, I also made some small mistakes and problems, which were pointed out to me by department leaders and related colleagues in time, which promoted my growth. During my three months in the operation and maintenance post, my work mainly focused on:
1. Maintain the office intranet;
2. Help solve colleagues' computer problems. Although this is the most basic foundation, we encountered some difficulties at first. Because the company used an English interface, it was uncomfortable and inefficient at first, but gradually I became familiar with it and some work began to be handy. The first month's work is still the basic work of operation and maintenance, but this month I am responsible for the paperless office of the company, doing the forms and processes of office OA for administration, personnel and development. Due to the tight time, I didn't find some minor mistakes, such as font type, size and correction methods. Fortunately, with the support and understanding of colleagues, OA is more perfect and smooth. In the second month, the application of all kinds of monitoring software and the installation of all kinds of monitoring equipment were completed. In order to ensure the normal operation of the company's power and system, our operation and maintenance work has become particularly important. Our NOC has subdivided the operation and maintenance work, ensuring that the company is on duty 24 hours a day, and the day shift and night shift start to be on duty every 12 hours. The main work is to monitor Cacit, Nagios, Cdrtool, Smokeping and Vmare. If there is any alarm or other abnormal situation, we will notify the corresponding person in charge at the first time and solve it in the shortest time, so as to ensure the normal operation of the server throughout the year. In the third month, the department leader arranged me as a normal class, mainly responsible for the daily operation of the company, the maintenance of basic equipment and the handling of abnormal situations. After the deployment of the company's new computer room was completed, I actively participated in it. I learned a lot from the network wiring in the computer room, the arrangement of network cable distribution, the monitoring of network wiring points, and the sorting and classification of server power cables.
2. My work achievements: If I only learned about the company from the introduction in the first few days, my understanding of the company is only superficial, then as time goes by, I have a deeper understanding of the company. The strict requirements of the company's leaders have enabled me to learn a lot of knowledge from the company that I didn't learn in the past, and not only gradually improved my technical skills, such as understanding the working principle of various computer accessories, general solutions to problems, and maintenance skills. And gradually get rid of the irregular operation in the work, the matters needing attention in entering and leaving the computer room, the process of reception staff, the standardized operation of daily maintenance, the details of construction attention and so on. Let me realize that as an operation and maintenance engineer, it is our responsibility to ensure the normal operation of the company's network and various equipment, and it is our obligation to maintain the cleanliness of various network cables in the computer room.
Three. My shortcomings and improvement: In the past three months, with the enthusiastic help of the manager and colleagues in the company, I have made some progress. Generally speaking, I think I still have the following shortcomings and deficiencies:
1. can't apply system network knowledge more flexibly, and lacks experience in dealing with related abnormal faults;
2. Sometimes the ability to work is not enough, the initiative of the work is not enough, the foresight and creativity of the work are not enough, and there is still a certain distance from the requirements of the leaders;
3, business knowledge, especially the knowledge of local area network, is still slightly lacking. Be brave after shame. In the future work process, I will be more strict with myself, 1, constantly strive to enrich myself, learn all kinds of knowledge such as network architecture, computer software and hardware maintenance, improve my efficiency in dealing with emergencies, and build some common services. 2. In my future work, I will also take the corresponding certificate exam to improve myself, make good use of my spare time to learn IT knowledge, build various servers and network knowledge, and improve my English.
Advice to the company: As far as my work scope is concerned, I have been in the company for a short time, and there are still many places to learn, some of which are not familiar with. But I believe that with the support of leaders and colleagues, I will increase the maturity of my work and do my best for the development of the company.
My summary is not comprehensive, and I hope the leaders will give me more valuable advice. In my future work, I will treat people as always:
Be kind to others and work: strive for perfection and constantly improve your technical level and comprehensive quality. Here, I apply to become a regular employee, hoping to become a regular employee of the company. I asked the leadership for approval.
Summary of Operation and Maintenance Work since Mode 6 With the correct leadership of the company leaders and the strong support of colleagues, my work table is mainly based on the following aspects, based on safe production, with improving the operation and maintenance indicators of the team as the main task and aiming at user satisfaction:
I. Maintenance of Computer Room
Regular dust removal and maintenance of the power supply and private network equipment in the front-end computer room ensure the normal operation of the computer room and the safety and trouble-free transmission. The maintenance and overhaul of the air conditioner in the transmission room ensures the normal operation of the equipment and avoids the alarm caused by the indoor temperature exceeding the limit. The transmission room power supply and the front-end UPS power supply are discharged regularly. Clean up the equipment assets of the computer room and supplement the drawings. According to the duty regulations of the computer room, do a good job in the duty, operation and power supply of the computer room, truthfully fill in the duty log of the computer room according to the actual situation of the computer room, measure the output of the rectifier cabinet, battery pack and DC power distribution cabinet once a week, clean up the dust and dust screen of the equipment once a week, and maintain the generator to ensure emergency power supply. No abnormalities were found for half a year.
Second, the operation and maintenance service quality indicators
There are more than 1 10000 households in the maintenance area, and now there are three front-end computer rooms: * * 300 buildings, * * 4850 sets of equipment (including: optical transceiver, EOC, ONU) and 18 optical junction boxes. Due to the previous network design, a set of equipment covers up to 72 households. There are more than 150 work orders every day, especially broadband. Since February this year, the sub-front end has been adjusted several times, and in February, April and June, it cooperated with municipal company data center, set-top box manufacturer and OLT manufacturer to conduct several broadband tests and expansions to solve the problem of repeated dialing by users. However, according to the requirements of the company, Power Grid Group has done a lot of interpretation and testing work. Power grid service quality indicators all meet the company's requirements: the compliance rate of returning orders is higher than the company's regulations: 98%, the timely rate reaches 95%, and the service satisfaction reaches 98%. Service indicators meet the requirements of municipal companies.
Third, promote new skills.
With the vigorous development of FTTH, every computer room in the grid increases the risk of OLT. When installing, ask the installation colleagues, consult modestly and master some FTTH knowledge. At the same time, I studied online, watched the communication of colleagues in the group, and accumulated some experience, so I applied what I learned. I need to install an IP set-top box in my power grid. I led everyone to install 200 hotel IP set-top boxes, and the whole group learned the new installation workflow, precautions and practices on the spot. Now all the staff have met the company's maintenance requirements when installing IP set-top boxes and maintaining them, and have applied the theory to practice.
Fourth, network optimization.
In terms of network optimization, we cooperated with network companies to expand and rectify the IPQAM of three sub-front-ends. In May, we expanded the capacity of Cisco 80GIPQM. In June, we added a 6K switch and a beacon OLT, and cut off the wiring of the computer room at the sub-front end. Three unopened 8-beam splitters were opened, and they participated in the cutting work of 144 core and 96 core, and expanded two buildings.
First of all, ensure the transmission safety of sub-lines and trunk lines, strengthen the management of cable TV transmission safety, ensure network security, and achieve "diligent inspection, diligent visit, diligent inspection, diligent reflection and diligent communication". In case of emergency, report it at the first time, and the emergency repair personnel will carry out maintenance in time. Ensure the safe transmission of signals in the whole area, so that the cable TV signal quality is always in a good state. Secondly, customer service: customer first, caring service, improve maintenance efficiency. To change the previous thinking, we should base ourselves on the present, recognize the present situation, face the market, do a good job in service, find users with technology, get users with quality, retain users with service, and consolidate the market with image.
But there are still some personal shortcomings. I believe that only when the service is in place, the signal quality is improved, users really establish contact and gain the trust of users, and with the efforts of other colleagues, users' complaints will gradually decrease. Down-to-earth, pay close attention to implementation, work hard, lay a good foundation for next year's work, create conditions, and successfully complete the company's indicators and tasks.
