Aiming at the problems of limited space, insufficient control precision and positioning reliability of hydraulic support in fully mechanized mining face of extremely thin coal seam, an intelligent electro-hydraulic control system for ZY4800 / 06 / 16.5 hydraulic support is designed. The system is composed of support controller, pressure sensor, displacement sensor, inclination sensor, infrared ranging device, electro-hydraulic directional valve and local / remote communication bus. It can realize the functions of support height measurement, attitude detection, position recognition, automatic pressure compensation, follow-up control and safety alarm. In addition, aiming at the problem that a single sensor is susceptible to underground dust, electromagnetic interference and roof disturbance, this paper proposes a multi-sensor feature fusion positioning method to improve the stability of hydraulic support position perception. The system can provide reference for automatic control and intelligent mining of hydraulic support in extremely thin coal seam.
