Abstract

The invention provides a sensor calibration system and method for fully mechanized coal mining face, wherein the system includes: an angle calibrator, which is arranged on the hydraulic support where the sensor to be calibrated is located, and the angle calibrator and the inclination sensor have the same number of measuring axes. It is used to measure the attitude angle of the hydraulic support and send the angle of the installation bracket to the controller; the angle calibrator receives the sensing signal sent by each inclination sensor; the angle calibrator combines the attitude angle, the sensing signal of each inclination sensor and The signal strength is sent to the controller; the controller controls each inclination sensor to send sensing signals to the angle calibrator in turn; according to the signal strength, it is determined that the inclination sensor closest to the angle calibrator is the calibrated sensor; the attitude angle is sent to the calibrated Sensor: After the calibrated sensor receives the attitude angle, it performs a calibration operation according to the attitude angle to keep its own sensing signal consistent with the attitude angle. The above solution improves the efficiency and accuracy of the calibration of the inclination sensor.

Description

technical field [0001] The invention relates to the technical field of hydraulic control, in particular to a sensor calibration system and method for fully mechanized coal mining face. Background technique [0002] In the automatic working face of the coal mine, it is necessary to use the inclination sensor to measure the attitude angle of the hydraulic support top beam, cover beam, four-link and base, so as to realize the monitoring and control of the support attitude. Limited by the structural characteristics of the hydraulic support and the external dimensions of the inclination sensor, the inclination sensor needs to weld the installation bracket on the hydraulic support first during the installation process, and then fix the inclination sensor on the installation bracket, and the welding of the installation bracket relies on manual operation , there may be a certain deviation between its angle and the design angle, resulting in a certain error between the measurement da...
