[0019] Working principle:

[0020] S1. First, the sensor data acquisition platform is enabled. The main function of the platform is to collect the status information of the high-voltage tower pole. The piezoelectric acceleration sensor is installed on the top of the transmission tower and in the tower to measure the acceleration changes in 4 directions at 2 heights. The measurement range is ±2g, the resolution is 5×10-5g, and the frequency response range is 0.25Hz. The temperature and humidity sensor collects temperature and humidity signals. The working principle of the ultrasonic wind speed and direction sensor is to use the ultrasonic time difference method to measure the wind speed. The wind speed and wind direction are calculated by the time difference of ultrasonic waves propagating in the air, which effectively overcomes the defect of easy wear of mechanical anemometers. The wind speed and wind direction integrated sensor based on the ultrasonic principle is selected in this project. It is installed on the transmission tower body about 10m above the ground to measure the wind speed and direction around the transmission tower. The measured wind speed is 0~60 m / s, the measurement accuracy is ±0.3m / s, the wind direction measurement range is 0~359°, the measurement accuracy is ±3°, and a differential pressure static level is used to monitor the multi-point relative settlement of the tower foundation, that is, the change of the vertical displacement of each measuring point relative to the reference point, so as to accurately calculate the relative settlement of each measuring point. The monitoring module is composed of a liquid storage tank, an imported ultra-high precision core, a specially customized circuit module, a protective cover and other components. The settlement system is composed of multiple sensors of the same model. The liquid storage tanks are connected by ventilation pipes and liquid pipes. The reference point is placed at a stable horizontal base point. When the measuring point rises and falls relative to the reference point, it will cause changes in the pressure of each point. By measuring the changes in the sensor pressure, the rise and fall changes of each measuring point relative to the horizontal base point are calculated. The data filtering and amplification unit filters the data for noise and then displays the data in a high-definition manner and organizes it into the warehouse, and obtains the status data group A;

[0021] S. RS485 conversion terminal collects data according to the sensor data collection platform for transmission conversion. The 4G conversion unit and the frequency hopping transmission unit complete the transmission of 4G data and frequency hopping. The GHz microwave unit does not need authorization to access through the microwave in the 4GHz frequency band, and the intermediate protocol import unit includes the 4G microwave transmission import of the service discovery protocol unit, the logical link control unit, the telephone communication protocol and the serial port simulation protocol, so as to obtain the services in the 4G network, and finally the data output unit outputs them to the positioning calculation end in a directional manner. The communication between the monitoring station and the server is realized through the 4G module. The data service downlink rate can reach up to 100Mbit / s, and the uplink rate can reach up to 50Mbit / s, which meets the temperature and voltage requirements of the power site, has a lightning protection design, the RS485 interface surge protection 1kV, and the RS485 interface power supply isolation to prevent the power environment such as arc damage to the equipment, which is suitable for the application environment of this system.

[0022] S3, the load obtains the electric energy of the solar panel through the solar controller. When the energy generated by the main power supply system is sufficient, the excess energy is stored in the battery; when the generated energy is insufficient, the insufficient part is provided by the battery. The power supply system is mainly composed of solar power supply component panels, polymer lithium batteries and controller components;

[0023] S. The MCU single-chip microcomputer performs maintenance based on the data. The data receiving unit receives the operation and maintenance information of the sensor data acquisition platform, directly checks the abnormal status data of the high-voltage tower pole output, the vibration acceleration monitoring unit monitors the acceleration changes in four directions at two heights of the high-voltage tower pole, and checks for abnormal voltage. The temperature and humidity data monitoring unit performs real-time monitoring of humidity based on the real-time data of the temperature and humidity sensor. The settlement monitoring unit monitors the multi-point relative settlement of the high-voltage tower base, that is, the abnormal value of the vertical displacement of each measuring point relative to the reference point, checks the status information of abnormal temperature, and calculates the wind speed and wind direction values ​​according to the time difference of propagation in the air input to the sensor data acquisition platform collection device through the wind speed and direction monitoring unit. At the same time, the data display unit displays the status data, and the sound and light alarm unit alarms for abnormal data of the high-voltage tower pole.

[0024] The present invention provides a tower attitude monitoring device based on CORS, which has the following beneficial effects:

[0025] The present invention aims at the situation that high-voltage transmission towers in areas prone to geological disasters such as mining areas are prone to settlement, tilt, translation and collapse accidents. The present invention uses continuous reference station service technology, GNSS (mainly Beidou) carrier phase difference technology, and static level monitoring technology, combined with existing space measurement technology and other electronic technologies, to monitor the posture changes of towers and perceive the settlement and displacement of towers.
