An online automatic monitoring system for reservoir safety

Abstract

The invention discloses an online automatic monitoring system for reservoir security. The system comprises a dam seepage monitoring device, a water level monitoring device, a dam sinking and translating monitoring device, and a wireless communication network and background management system. The dam seepage monitoring device, the water level monitoring device and the dam sinking and translating monitoring device are incorporated to and transmit the onsite monitored data to the wireless communication network and background management system respectively; and the background management system makes early warnings and determination according to the onsite monitored data; and if the monitored data reach the preset value, early warning information comes out. According to the invention, through the connection of onsite monitored data from the dam seepage monitoring device, the water level monitoring device and the dam sinking and translating monitoring device to the wireless communication network and background management system, the background management system is capable of making early warnings and determination according to the onsite monitored data; if the monitored data reach the preset value, early warning information comes out. In this way, comprehensive monitoring becomes available to the security of the reservoir and practical basis can be provided for future reservoir construction.

Description

technical field [0001] The invention relates to a reservoir monitoring device, in particular to an online automatic monitoring system for reservoir safety. Background technique [0002] Reservoir dams are common engineering projects in the construction of water conservancy projects. Dam failures occur frequently, and the huge disasters caused have attracted great attention from the international community. The safety and stability of the dam plays a very important role in ensuring the safety of people's lives and properties, so it is necessary to ensure the safety and stability of the dam during the operation of the reservoir. The main factors affecting the safety of reservoir dams are dam body deformation, leakage and excessive water level. Real-time monitoring of these two parameters is the main guarantee to ensure dam safety.

[0003] The detection status of the original reservoir and the problems in automation: In the traditional reservoir operation and management, the detection of the dam is all composed of manual detection

[0004] After searching, there is almost no automatic monitoring system composed of self-developed monitoring instruments at home and abroad. They all use different types of sensors and instruments to form an automatic system. The structure of the system is cumbersome, the connection is complicated, the installation is extremely inconvenient, and the cost higher

[0005] The existing automatic monitoring system composed of monitoring instruments is basically composed of wired network, the system line is complicated, there are many instrument manufacturers, the communication protocol is cumbersome, and the control center also needs different data interface modules; the huge system technology cost is high, and the maintenance cost High, and there are many failure rates, and, in the wilderness, the mixture of strong and weak electricity is extremely vulnerable to lightning strikes

The control centers of most reservoirs have experienced lightning strikes, resulting in varying degrees of damage
