Fan: the intelligent development trend of construction machinery

The intelligent development trend of construction machinery not only means that the traditional working mode of construction machinery needs to be changed, but also the working process of machinery needs to be changed, and it should be integrated into the working process of construction machinery to realize intelligence, so as to improve the working efficiency of construction machinery, reduce resource consumption and enable construction machinery to complete the requirements of construction projects efficiently. This paper discusses the intelligent development trend and development of construction machinery.

Keywords: construction machinery; Wisdom; Development countermeasures

Modern engineering technology needs not only integration conditions, but also certain wisdom conditions. With the continuous expansion of modern construction scale, traditional construction machinery technology has been difficult to adapt to the scale requirements of construction projects. In order to adapt construction machinery to the current development trend of construction engineering, it is necessary to change its development direction, integrate current science and technology, and integrate intelligent technology to realize intelligent management of monitoring system, detection system, prediction system and maintenance system of construction machinery, thus providing more efficient construction technology for modern construction engineering.

1 Development trend and present situation of intelligent construction machinery

1 intelligent control technology of construction machinery and development trend of single machine integration. Intelligent control technology and single machine integration technology of construction machinery mainly include electro-hydraulic control automatic shift transmission, programming control, unmanned operation and other technologies. As far as the intelligent development trend of construction machinery in China is concerned, its automatic shift technology is widely used at present. This technology can effectively improve the quality, bring more benefits to the operation technology of construction machinery, effectively improve the technical efficiency in technology application, reduce the work intensity and workload of traditional construction machinery, and also reduce the workload of staff to a certain extent. Among them, automatic gear shifting devices mainly include hydraulic type and electro-hydraulic type. The application mode of hydraulic pressure is mainly to convert the parameters such as the running speed of the vehicle and the starting degree of the accelerator into oil pressure signals, and control the shift valve of the vehicle by using the oil pressure signals, so that the shift valve of the vehicle forms an automatic shift mode. The electro-hydraulic application mode can convert the parameters such as driving speed and throttle opening generated during the driving process of the vehicle into signal forms, and then input them into the electronic shift controller, which controls the shift valve, thus forming an automatic shift mode, which ensures the safety of the vehicle. Electro-hydraulic automatic shift technology can be compatible with construction machinery, which is an important trend to realize electro-hydraulic integration of construction machinery and an important channel to innovate intelligent working conditions [1].

2. Development trend of intelligent monitoring, maintenance and detection technology for construction machinery. The intelligent monitoring of construction machinery basically takes electronic intelligence as the core. The main application of this technology is on-line monitoring of complex situations encountered in site construction, a series of automatic monitoring of construction machinery, and remote diagnosis and maintenance of faults in construction machinery operation. The main purpose of this intelligent engineering technology is to digitize, intellectualize, manage and maintain the mechanical failure phenomenon and on-site monitoring work. Since the 20th century, microcomputers have been widely used in China. Many foreign construction machinery enterprises began to try to apply microcomputers and started experiments in many fields and equipment. After years of experiments, the intelligent operation mode of construction machinery began to be unanimously recognized by the construction machinery industry, and gradually applied to various fields of construction machinery, and achieved considerable results. In recent years, many foreign manufacturers have begun to install electronic monitoring devices in the output and storage parts of fault data sources, so that maintenance personnel can use the output and input of fault codes to analyze faults when inquiring about fault factors, so as to find out fault factors and fault types more accurately. Compared with other countries, the application of intelligent monitoring in the field of construction machinery in China is still weak, its fault diagnosis technology and monitoring technology are still in the primary development stage, and its intelligent monitoring system has not been widely used in China, which hinders the development and perfection of construction machinery and equipment in China to some extent [2].

Intelligent management based on network cluster. Construction machinery has a wide range of applications, and it has a very important application in different construction projects. As far as highway construction is concerned, different types of construction machinery are often needed in the construction of high-grade highway pavement. At the same time, many machinery and equipment have the characteristics of randomness in the construction process, which leads to the inability to form a special mechanical configuration for construction projects in the actual construction process. Therefore, when the construction unit invested a lot of equipment funds for the project, the mechanical device was not effectively applied, which has become a common problem in the application of construction machinery in China. Faced with the need for high efficiency and various types of construction projects, projects often need to invest more money in construction equipment. At the same time, in the construction coordination, the cluster has many mechanical equipment and limited coordination ability, which directly affects the construction quality and progress of construction projects. Therefore, in the configuration and optimization of construction machinery clusters in construction projects, it is necessary to give full play to the cooperative work of clusters to reduce construction costs. In recent years, after the frequent problems of engineering construction in China, specialized researchers began to do a lot of research. Although many theoretical achievements have been made in construction machinery, there is no scientific and perfect means so far. Therefore, in the process of engineering construction, its theoretical achievements have not been effectively applied. At present, taking network cluster as engineering intelligent management and integrated control is the problem of continuous improvement of current engineering project construction. This equipment component can effectively optimize the configuration mode of the cluster, intelligently manage the construction progress and ensure the construction progress and quality of the construction project [3].

2 intelligent development of construction machinery countermeasures

1 Comprehensive utilization of technology. Facing the diversified development trend of current construction projects, its single mechanical equipment configuration can no longer meet the construction needs of current projects. In order to make modern construction machinery meet the diversified needs of construction projects, China's construction machinery needs to expand its application scope, make overall arrangements for digital technology, intelligent technology, network technology and other technologies, comprehensively utilize them, change the application mode and scope of traditional construction machinery, and make construction machinery develop in a comprehensive direction. In the comprehensive utilization of intelligent technology of construction machinery, construction machinery needs the technology of control system and integrated system, which makes this technology form the core technology and unit technology in the intelligent development. Comprehensive utilization of various technologies can not only effectively improve the efficiency system of construction machinery, but also fully combine China's national conditions to realize independent innovation and application of construction machinery technology, promote the development of new leading products of construction machinery, and make China's construction machinery products realize intelligent development. At the same time, it will also help to form a leap-forward development in a short time, improve the competitiveness of China's construction machinery, thus forming an industrialized operation mode and laying a good foundation for the future development of the construction machinery market.

Development and application of fault diagnosis technology for construction machinery. Fault is a common technical problem in the execution of construction machinery. This problem not only affects the normal operation of construction machinery, but also brings great losses to construction machinery. In order to improve the stability of construction machinery and equipment, a fault diagnosis sensor system is installed in the key parts of construction machinery and equipment in China, and the sensor is used to collect the previous execution state of construction machinery. For example, the oil temperature and oil pressure of engine equipment are detected, and the parameters such as hydraulic system, fuel quantity and braking system in key engine systems are accurately detected. At the same time, according to the different fault types of mechanical equipment, different levels of alarm devices are adopted to effectively monitor the construction machinery during operation. Once the fault phenomenon is found, it will immediately call the police, so as to prompt the construction machinery to take improvement measures at the first time, record the fault factors and take preventive measures to reduce the failure probability of mechanical equipment.

Apply artificial intelligence, network communication and other scientific and technological technologies. The intelligent development of construction machinery is related to the technical support and innovation. The intelligent maintenance system and remote monitoring technology of construction machinery must be integrated and supported by science and technology, thus promoting the effective development of intelligent technology of construction machinery. For the fault factors of construction machinery, remote monitoring technology and sensors can be used to effectively detect the fault factors of mechanical equipment. In this regard, the Engineering Machinery and Equipment Division will collect the fault factors of equipment, analyze the fault factors and preventive methods of machinery as a whole, and diagnose the most common fault phenomena and fault parts of machinery and equipment. At the same time, according to the failure mechanism, it mainly includes hydraulic system, device parts, radiator, brake and other system parts. Then, a perfect fault mode system and database system are established according to the fault phenomenon of typical components, and a perfect fault data system is established according to the fault factors of mechanical equipment, so that when mechanical equipment encounters this fault phenomenon in the future, it can effectively use intelligent technology for maintenance and effectively avoid blind maintenance methods.

4. Develop intelligent management system of construction machinery-cluster control system. Before the formal construction of the project, the dispatcher needs to know the mechanical equipment system in detail and master the on-board control system of the construction vehicle in detail. According to the current actual situation, optimize the fleet configuration, rationally plan the configuration of mechanical equipment and vehicles, conduct scientific scheduling on a regular basis, and scientifically arrange the execution trajectory and operation mode of construction vehicles and mechanical equipment. At the same time, it is necessary to carry out regular maintenance and maintenance of construction machinery and equipment used in on-site construction projects, strengthen the management of machinery and equipment, accurately understand the fault factors of various machinery and equipment, and improve the maintenance ability of construction machinery. In addition, the intelligent management system of construction machinery can effectively collect the construction data of the construction site to a certain extent, reasonably configure and schedule the work clusters, so as to do a good job of collaborative control and form good network communication among the clusters, thus forming intelligent control and operation.

5. Develop intelligent computer cluster control system. For the current intelligent building cluster system, the cluster control intelligent system not only needs to cover the basic construction machinery engineering, but also needs to have certain intelligent machine configuration, such as remote fault diagnosis system, remote fault maintenance system, airborne intelligent system and so on. These intelligent devices can make the construction team realize remote control and intelligent control at the same time, enhance the receiving intensity and efficiency of each group of signals, and also make the group automatically do system work and maintenance work when facing remote control, thus effectively improving the working efficiency of the group.

3 Conclusion

To sum up, compared with western countries, the development of intelligent construction machinery in China started late, and its application scope is still very narrow, and it has not been effectively applied in many fields. Facing the continuous expansion of construction scale in China, it has become an inevitable development path for construction machinery to develop in the direction of intelligence. This is not only the need of construction, but also the need of social progress. Judging from the current application trend of intelligent construction machinery in China, technologies such as single machine integration, intelligent management of network cluster, intelligent monitoring, maintenance and detection of construction machinery have been widely used in China, which has greatly improved the construction efficiency and quality of engineering projects. In terms of development countermeasures, China needs to realize the application of comprehensive technology, develop fault diagnosis technology of construction machinery, apply artificial intelligence and network communication to intelligent construction machinery, increase the application field and scope of intelligent technology, and accelerate the development speed of construction machinery.

Fan: Thoughts on Standardization of Construction Machinery and Equipment Management

Standardization of construction machinery and equipment management is helpful to improve equipment management efficiency and reduce equipment management cost, but the implementation of standardized management has long been a difficult point in the field of construction machinery and equipment management in China. Limited by the imperfect system, the quality of managers, the implementation of convergence and other multiple problems, the implementation of standardization of construction machinery and equipment management is not effective and targeted. This study will focus on standardization and analyze the existing problems, and then put forward the corresponding promotion and improvement strategies.

Construction machinery and equipment; Management; standardization

Strengthening the management of construction machinery and equipment is the key measure to improve the use efficiency of construction machinery and equipment, control the management cost and highlight the economy. At present, with the increasing number of various construction projects, various problems in the management of construction machinery and equipment have gradually emerged. This study focuses on the management of construction machinery and equipment, focusing on standardization, and combining with tower cranes and other equipment for specific analysis. This research has certain validity and practical application value.

1 summary of management standardization of construction machinery and equipment

Construction machinery is the most important mechanical equipment in China's infrastructure construction. According to the existing technical standard system, China's construction machinery industry is divided into five professional fields: earthmoving machinery, construction machinery and equipment, lifting platforms, industrial vehicles and pneumatic tools for rock drilling machinery. The research on standardization of construction machinery in China began in the 1960s. In terms of standardization, China has experienced more than 50 years of development, and gradually formed a set of national standards and industry standards involving hundreds of construction machinery, and at the same time formed more than 1000 internal standards. Construction machinery standardization plays a very important role in industry development and product progress, especially in recent years, with the increase of engineering projects in China, construction machinery standardization has been further developed rapidly, and its role is more prominent. It is embodied in the following aspects. The first is to ensure the quality and efficiency of machinery. The quality of construction machinery and equipment depends on daily maintenance, and the key point of mechanical management is to improve the management level and efficiency of equipment to ensure that the equipment can maintain a good working condition. In the management of tower crane, actively implementing standardization can effectively control the management cost, at the same time, it can better maintain the mechanical state and make the equipment play its due role. The second is to save resources and control costs. With the application and development of professional technology in construction machinery management, more management behaviors are innovated and optimized, management standards are implemented, and the practical value of standardized management is highlighted. Only by standardizing the management of some large-scale equipment can we ensure the effectiveness of management, keep the equipment in good condition, and then ensure that all inputs are more reasonable and reflect the economy of management. Third, it is helpful to implement the standardization of project management. The standardized management of mechanical equipment is the most important part of project management. Only by achieving standardization can we better control management costs and improve the effectiveness of production and operation. The purchase price of tower crane is high, and the daily management cost is high, so it is more necessary to realize standardization. Generally speaking, the standardized management of equipment is also conducive to improving the standardization level of production operations. The standardization of production operation comes from the standardization of all management links. Through the standardized management of mechanical equipment, the standardized management of the project can be further realized, the management potential can be stimulated, and long-term production and operation can be realized.

2 Analysis of the problems existing in the management standardization of construction machinery and equipment

2. 1 The use and maintenance of construction machinery are out of line.

In the actual project management, there is still a phenomenon that the use and maintenance of construction machinery and equipment are out of line, and the maintenance standards of construction machinery and equipment cannot be effectively implemented. The user and management unit of tower crane and other large mechanical equipment shall, in accordance with the requirements of management standards, formulate and implement corresponding equipment maintenance system. The system should include the main points of maintenance, management and use procedures of tower cranes, and at the same time highlight the requirements of inspection and maintenance specifications for key stressed structural parts, so as to avoid all kinds of safety accidents and nip problems in the bud. At present, some equipment users fail to effectively implement the daily maintenance standards of tower cranes and other equipment in time, which leads to the disconnection between equipment use and maintenance, which affects the use effect of equipment and brings certain security risks.

2.2 the quality and ability of construction machinery and equipment management personnel

The scientific and effective implementation of management standardization of construction machinery and equipment depends on the quality and ability of actual equipment managers and operators to some extent. At present, some managers of mechanical equipment lack the necessary awareness of standardized management, especially in the management of tower cranes, and lack the necessary standardized inspection before equipment installation, which leads to safety accidents during the installation and disassembly of mechanical equipment and has a certain negative impact.

2.3 Construction machinery and equipment management standardization rigor is not strong.

It is difficult to guarantee the rigor of construction machinery and equipment management standardization, which further makes the standardization effect of construction machinery and equipment management not outstanding. Standardization of construction machinery management is a continuous work. Only by effectively embodying the rigor of standardization can we ensure the pertinence and professionalism of management. In the actual process of standardization implementation, the problems of not strict and not in place are prominent, which leads to the management of construction machinery and equipment becoming an empty talk.

3 Construction machinery and equipment management standardization implementation strategy

The effective implementation of standardization of construction machinery and equipment management can effectively improve the overall level of construction machinery and equipment management and highlight its economy and practicality. Standardization of construction machinery needs to be strengthened, implemented and improved. A href ='' target =' _ blank'> What are the disadvantages of coughing? [6] obsidian thistle? What is the framework? /p & gt;

3. 1 Strengthen the implementation of management standardization

Ensuring the effectiveness of management standardization is the basis of construction machinery management. Under the system of system and specification requirements, only by paying attention to implementation can we ensure the management effectiveness of various mechanical equipment such as tower cranes. With the corresponding management standards, effective implementation of the standards is an inevitable move for the management of construction machinery and equipment. At present, there are detailed management standards for daily maintenance, repair, installation and use of tower cranes. Only by implementing the standards can enterprises achieve standardized management, so strengthening implementation is the basis and necessary premise of standardization.

3.2 improve the overall quality of management personnel

The effectiveness of management standardization of construction machinery and equipment depends largely on the comprehensive quality of managers. Therefore, it has become a top priority to improve the comprehensive quality of equipment managers, and then improve the management level. Enterprises need to strengthen daily training and education, so that equipment managers have a good sense of standardization, can actively and effectively complete various management work, implement standardization work, and achieve the due effect of standardized management.

3.3 Establish a dynamic standardized management system

It is a key measure to realize construction machinery management around dynamic standardization. Dynamic standardization can effectively improve the effectiveness and professionalism of management. For the standardized management of tower crane, dynamic standardization makes the management requirements change with the development of the equipment itself and the actual management requirements. Dynamic standardization can effectively control the cost of equipment management and promote the timely and effective implementation of the latest management standards and norms, thus improving the overall level and quality of equipment management and ensuring the safety of equipment management.
