Mining hydraulic support tilt angle sensor system error correction method and system

The invention provides a mining hydraulic support tilt angle sensor system error correction method and system, and belongs to the technical field of tilt angle sensor error correction. The problems that the timeliness is poor, and time and labor are wasted during error correction of an existing hydraulic support base tilt angle sensor system are solved. Comprising the following steps that a hydraulic support dip angle-mining height relational mathematical model is established, wherein an electric hydraulic control system automatically collects dip angle and mining height data of a hydraulic support on a working face in real time and stores the data to a crossheading main control computer; error correction system triggering and calibration data set sampling; calibration data set processing including mining height data interpolation and caving shield pitch angle and top beam pitch angle error processing; calculating the error correction amount of the tilt angle sensor: dividing the calibration data set into a c
