Research And Implementation Of Dam Seepage Monitoring System Based On GPRS

There are numerous of dam especially earth-rock dam in China, and the most common destruction for earth-rock dam is seepage damage,it does great harm to dam and even cause dam break, in order to detect the abnormal situation of the dam as early as possible, it makes it necessary to develop dam seepage monitoring system.The thesis introduces the external and internal researching actuality and advantages or disadvantages of the dam seepage monitoring system, also carries out further research with the wireless communication technology and modern monitoring technology. And the dam seepage monitoring system with remote monitoring function on GPRS is proposed. The system mainly consists of single-chip microcomputer terminal and the monitoring center, which proved to carry out the function of long remote control and to be beneficial to expansion for monitoring system.According to the seepage monitoring characteristics and content, the monitoring parameters is selected, and a kind of dam seepage monitoring terminal based on vibrating wire settlement sensor is developed, moreover, the function module of the hardware interface is perfected. Then the GPRS network technology is researched and designed one kind of GPRS data transmission network. In addition, networking of the monitoring is designed and the GPRS communication module is designed and, and the communication between the monitoring terminal and the GPRS module is realized by formulating communication agreement.In this thesis, the monitoring system of the PC software is designed by modifying VB and SQL Server 2000, the communication between PC software and GPRS module is realized by setting up the socket connection, for this connection, the monitor real-time data acquisition is realized. In addition, design and production of the experiment model indoor dam, and the system testing platform is set up by using this kind of dam module. Also, the testing and debugging of the monitoring system is carried out in the platform, the feasibility is proved with the experiment. At last, the content of the seepage researching calculation is conformed by using the dam seepage calculation method, and also, the theoretical dam model for the system is set up and have a calculating for the collected data come from the system, in addition, the safety evaluation is made through the calculation result.
