Desing Of Deformation Remote Automatic Monitoring System For The Existing Lines Of Metro

IProximity both new underground rail line, and large municipal projects, civil foundation works and rail subway structure may produce a shift in deformation, which may affect the safe operation of the subway; Therefore, in the proximity of existing construction line on the existing rail line of the tunnel structure and deformation monitoring in ensuring the safe operation of the MTR significant. This paper use the existing line of Guangzhou Metro section deformation monitoring mission as the background, the total station used to monitor deformation, static water level, Bassett Convergence System, fixed automatic inclinometer monitoring technology such as displacement, methods and conduct the comparison and analysis of the various methods used in Haizhu Square advantages and disadvantages of tunnel deformation monitoring, designed by Leica total station robot detection and monitoring program to be realized. For remote transmission of existing systems do not have the shortcomings of the remote transmission of the program, the appropriate hardware and software system designed to achieve real-time remote monitoring of data transfer, so that the automation of the entire system has reached domestic advanced level.The System use the Leica TCA2003 Total Station (commonly known as measurement of the robot) as the core, designed to measure the robot using automatic target recognition ATR (Automatic Target Recognition) function to monitor the disposition pattern deformation, with its GEOCOM development environment is developed based on GPRS Remote automatic reporting subsystem. The system has been a year of operation, stable, high precision, accurate and timely data, and that was affirmed deeply by clients. This paper consists of four parts:first, the analysis of the tunnel deformation monitoring methods at home and abroad and related equipment, combined with the current characteristics of tunnel construction and put forward the necessity of the development of the present system, and deeply discussed the,design of relevant technologies in detail. Second, it presents the overall design of the system, the function of each module, structure and operating principle are discussed. Then introduced the system in the practical application of the construction site, and researched the experimental date, to summarizes the strengths and weaknesses of the system. Finally, summarized the results obtained of the design of the system, and put forward which is still needs to be improved and further studies.
