Network engineering graduation thesis model: application of GIS technology in radio and television network engineering1application case of GIS technology in domestic radio and television network engineering management
According to the problems existing in the resource management system of Zhejiang Jiaxing Radio and Television Network of Hanjia Company, GIS technology is used to optimize and rebuild its business process, hoping to realize the standardization of network planning and design and the dynamic management of network resources.
1. 1 management object
At present, the objects of radio and television network resource management mainly include the following aspects:
① Computer room data. It mainly includes equipment information and basic information. The former mainly includes network access equipment, racks and other data equipment, while the latter mainly includes the computer room number.
② Spatial resource data. Contains regional information, computer room information, etc.
③ Line equipment. Mainly including optical cables and cables and other equipment.
④ Connect the equipment. It mainly includes junction box, optical junction box and so on.
⑤ Project data. It mainly includes all kinds of data in the construction of engineering projects, mainly referring to the project name, etc.
⑥ Other information, such as logical resources, can be customized and developed according to the actual situation.
1.2 development platform
The CATV network resource management system belongs to a large-scale system, and the development platform should be selected before the transformation, mainly including the selection of development language, GIS platform and database development platform. At present, there are many GIS development platforms. For example, in the development of the project, you can choose SuperMap Company to use the mature Soltu platform.
1.3 design process
GIS design. SuperMap component GIS is developed by standard Ac-tiveX component mode and embedded in the popular visual advanced development language environment, which can be used for object-oriented and visual programming design in various development tools. Combined with the actual design of engineering projects, fully combined with various third-party ActiveX components, the functions of GIS are infinitely expanded. Functional design. Radio and TV network resource management system involves a wide range, this step should be combined with the actual situation to organize these functions and expand the system. The best measure is to organize the functions of the system hierarchically according to the structural characteristics of network resources, and adopt the data updating mechanism with engineering as the main line, thus drawing the hierarchical diagram of the system functions. Data structure design. With the implementation of the project, the data structure can be refined and designed. For example, the object information of network resource management can be divided into project information and resource information. System implementation. After all the above aspects are designed, the system can be realized, which is the main flow of the whole project. A lot of data information in this project contains geographic information components. This step needs to combine the existing local area network, workstations, servers, basic maps, documents and other resources for reasonable organization to ensure the realization of the system. This paper integrates Jiaxing photoelectric network resource management system through the above process, and the figure 1 shows the management of pipe and rod engineering equipment by this system, such as quantity statistics. For another example, you can also make statistics on the selected area. First, in the map toolbar-click the f(x) statistics drop-down menu, select regional statistics, and then the little finger icon will appear. Click with the left key and a confirmation dialog box will appear. After confirmation, a selection window will pop up and check the equipment to be counted. After statistics, click OK again to open the interface.
2 conclusion
To sum up, GIS technology has developed into a mature technical category, and its application in radio and television network engineering management will surely achieve good management results. With the further development of information technology, the management mode of China's radio and television network project will be further optimized.
Network engineering graduation thesis: research on farmland irrigation network engineering construction; 1 Farmland Irrigation Water Source Project.
Hongwei Irrigation District, Lianshang Electric Irrigation Station, Southern Central Water Supply Project, Motan Reservoir, Xiye Reservoir, etc. are a number of water source projects that integrate drinking water for people and livestock, agricultural irrigation water and industrial water supply, with abundant water and obvious benefits.
2. Construction of farmland irrigation network project
2. 1 Zhangfeng reservoir irrigation pipe network system engineering construction
Zhangfeng Reservoir Irrigation Network System Project is the first main canal water conveyance project of Zhangfeng Reservoir, which provides reliable water source guarantee conditions for farmland irrigation in this county. Tree-shaped network and star-shaped water conservancy projects (Dongfeng Irrigation District, Hongwei Irrigation District, Yangquan Irrigation District, Southern Central Water Supply Project, Connecting Electric Irrigation Station, Xiye Reservoir, Wenling Township Water Diversion Project, Manghe Town Red Star Water Supply Project and Hebei Town) have been built in this county. The project involves 13 townships, 179 administrative villages and 65,438+825,000 hectares of cultivated land. After the project is completed, the economic income and living standard of the people in the beneficiary areas will be greatly improved, and the irrigation area can be increased by 1.33 million hm2.
2.2 Other irrigation network projects in the county
2.2. 1 The reconstruction and expansion project of Dongfeng Irrigation District is mainly transformed from four water source projects: Dongfeng Reservoir, Shanghe Water Diversion Project, Xihao Water Diversion Project (newly built) and Hongwei Reservoir. Taking Dongfeng Irrigation District as the main area, making full use of the increased water volume of Shanghe Water Diversion Project and Xihao Water Diversion Project, and connecting them with Hongwei Reservoir, not only alleviated the water shortage in the irrigation area to a great extent, but also expanded the irrigation area, especially solved the serious water shortage problem in the north of Dongfeng Irrigation District, which provided a basic guarantee for the adjustment of agricultural structure. After the project is implemented, the irrigation area can be increased by 0. 1.3 1 10,000 hm2.
2.2.2 Connecting Project of Beiliu Hydraulic Pump Station Irrigation District and Motan Reservoir Beiliu Hydraulic Pump Station Irrigation District is a medium-sized electromechanical irrigation station with Qinshui River as its water source, which has made great contributions to the improvement of people's production and living standards in this beneficiary area. However, in recent years, due to the influence of special climatic conditions, irrigation water in irrigation areas can not be guaranteed, and the sufficient and reliable water source of Motan Reservoir and the favorable geographical location between them provide a guarantee for the networking transformation of the two water conservancy projects. The project involves Runcheng Town, Beiliu Town and Dongye Town, with an irrigation area of 67,000 hm2.
