Wireless security monitoring system for large dam

Abstract

The invention relates to a wireless safety monitoring system for a dam, which comprises a monitoring point module for collecting field data and a remote monitoring station center in communication link with the monitoring point module, wherein the monitoring point module comprises a power supply module for supplying power to the monitoring point module, a sensor used for monitoring actual seepage line data in a piezometer tube, a CPU connected with the sensor and used for receiving and processing the data, and a lower communication module connected with the CPU and used for communicating with the remote monitoring station center by a GPRS or GSM mode, wherein the power supply module comprises a solar panel, a charge control circuit and a storage battery which are connected in sequence. The invention is supplied with power by solar energy, adopts the GPRS or GSM communication mode, does not need to be supplied with with commercial power and has high real-time monitoring performance, interference resistant capability and low investment cost. The invention is also provided with a sensor cleaning component for maintaining the accuracy of data and a water level alarming component for further knowing the safety condition of the dam.

Description

technical field [0001] The invention relates to a monitoring system, in particular to a wireless safety monitoring system for a dam. Background technique [0002] There are many rivers in our country, and the safety of river dams is very important, and it is very urgent whether the data of dam infiltration line can be measured stably and reliably and grasped in real time, which is an important basis for the analysis of dam safety. [0003] The dam seepage line data is obtained by this method: a small-caliber well is drilled at intervals on the cross section of the dam, and piezometric tubes are installed in it, and then the actual seepage line data in the piezometric tube is measured. At present, the actual soaking line data of many dams is obtained by traditional data station transmission monitoring technology. Although the data is collected automatically, it is powered by the mains and uses electromagnetic waves as the transmission method, resulting in poor anti-interferen...

Problems solved by technology

At present, the actual soaking line data of many dams is obtained by traditional data station transmission monitoring technology. Although the data is collected automatically, it is powered by the mains and uses electromagnetic waves as the transmission method, resulting in poor anti-interference ability and real-time monitoring performance. Yes, and cables need to be installed, which makes the installation cost high and the cycle long; the actual soaking line data of some dams is obtained by traditional wired transmission monitoring technology, but it is easy to cause common mode interference, high power consumption and also requires mains power powered by

However, many dams in China are distributed in places with inconvenient transportation, remote locations, and no reliable power supply conditions. Most of these places use manual measurement, and it is impossible to monitor the safety of the dam in real time
