Dam bank collapse detection wireless terminal equipment

Abstract

The invention relates to dam bank collapse detection wireless terminal equipment. An intelligent simulation stone for dam bank collapse detection comprises a dam bank slope inclination angle sensor, an MCU control module, an encoder, a wireless transmitting unit, a power module and an outer packing material, an output signal of the dam bank slope inclination angle sensor is connected into the MCU control module, and the MCU control module, the encoder and the wireless transmitting unit form a main control circuit. An output signal of the MCU control module is connected with the wireless transmitting unit through the encoder; and the dam bank slope inclination angle sensor, the main control circuit and the power supply module are arranged in the outer packing material through the sealed mounting box to form a simulation stone, and an antenna of the transmitting unit is exposed out of a shell of the outer packing material. Digital coding modulation technology is adopted, so that the anti-interference capability is improved; besides, the simulation stone body is made of light clay, heat insulation is achieved in summer, heat preservation is achieved in winter, the service life of equipment can be effectively prolonged, and the simulation stone body is not prone to being found or damaged artificially.

Description

technical field [0001] The invention relates to a wireless terminal device for dam bank collapse detection, in particular to a wireless intelligent terminal for dam bank collapse detection using a simulated stone shape. Background technique [0002] In flood control and emergency rescue, embankment inspection is an extremely important task. The Yellow River has higher requirements for the monitoring of river engineering dam bank hazards because of its sediment-rich characteristics. In order to control the Yellow River, many dams were built according to the river situation to regulate the water flow and prevent the embankment from breaking. The Yellow River dam bank will grow rapidly in a short period of time after it is in danger. Early detection and early rescue are very important. For water conservancy projects to carry out information-based supervision, it is necessary to develop and install timely and reliable river engineering dam bank danger monitoring, early warning a...

Problems solved by technology

[0003] The Henan Bureau has more than 10,000 river projects, and the annual inspection of dams consumes a lot of manpower and material resources. Even so, it is inevitable that there will be cases of missed inspections and reports, which will lead to small dangers turning into big ones, endangering the safety of flood control projects

Since 2003, many units have carried out automatic monitoring tests for rock collapse in river engineering, and there are still many problems: some tests are technically unfeasible; some tests are technically feasible, but the cost is high, which is not conducive to popularization; some test results are acceptable , but the equipment is exposed in the wild, and it is easy to be destroyed by human beings, resulting in false positives and false negatives

The previous wireless terminal equipment was deployed on the bank of the river dam, and its real-time performance was poor. In addition, it was hot in summer and cold in winter, which would cause system instability, as well as other destructive factors, which would cause its service life to be low and failure rate to be high.
