Multi-field integrated monitoring system and method for reservoir landslide water-level-fluctuation zone

A monitoring system for a reservoir landslide water-level-fluctuation zone, comprising two onshore monitoring stations, a plurality of integrated sensing units, and a server;

• wherein the integrated sensing unit comprises:
• a housing assembly, a control board, a water pressure and water temperature sensor, a cable sealing and clamping device, a signal receiving device, a three-axis acceleration sensor, and a temperature and humidity sensor;
• the signal receiving device comprises a signal receiving antenna and a signal processing module;
• the two onshore monitoring stations comprise a reference station and a mobile station;
• the reference station is equipped with a Global Navigation Satellite System (GNSS), a solar power supply device, and a 5G module, and is fixed outside a landslide boundary to obtain a reference position for landslide deformation monitoring data;
• the mobile station is equipped with the GNSS, an electromagnetic wave transmitting device, the solar power supply device, the 5G module, and a Controller Area Network (CAN) receiving module, and is arranged on a slope surface near the water and above a highest reservoir water level, to obtain position information of the integrated sensing units;
• the GNSS of the reference station is configured to obtain geographical coordinate information of the reference station as fixed reference coordinates and establish a relative coordinate system;
• the GNSS of the mobile station is configured to obtain geographical coordinate information of the mobile station, and establish a relative position within a coordinate system established based on the reference station;
• the solar power supply device of the reference station is configured to power the reference station and the solar power supply device of the mobile station is configured to power the mobile station and the monitoring system;
• the 5G module of the reference station is configured to transmit the position information of the reference station to the server and the mobile station;
• the 5G module of the mobile station is configured to receive the position information of the reference station, and transmit all sensor data and position data to the server for processing;
• the control board, the temperature and humidity sensor, the three-axis acceleration sensor, and the signal processing module of the signal receiving device are sealed inside the housing assembly;
• the water pressure and water temperature sensor is configured to measure a water depth, a water temperature, and a surge impact pressure;
• the cable sealing and clamping device is configured to prevent water or soil from entering the housing assembly, and prevent waterproofness of the housing assembly from being destroyed when a cable is dragged;
• the signal receiving antenna is arranged in the signal receiving device to receive electromagnetic wave signals transmitted by the mobile station;
• the control board is configured to process signals detected by the integrated sensing units and the received electromagnetic wave signals;
• the three-axis acceleration sensor is configured to measure position changes of the sensing units;
• and
• the temperature and humidity sensor is configured to monitor temperature and humidity changes within the housing assembly to help determine whether water has entered the housing assembly, and send alert information and immediately cut off power within the housing assembly to protect circuits when humidity exceeds a certain value.
