Abstract

The invention provides an electromagnetic pilot valve driver. The driver comprises an input module, a power supply processing module, a storage unit and a central processing unit (CPU) processing module, wherein the input module is used for receiving a power supply signal and a control signal which are transmitted by a controller of a hydraulic bracket; the power supply processing module is used for receiving the power supply signal transmitted from the input module, and converting the power supply signal into a required voltage to supply electricity to the electromagnetic pilot valve driver; the storage unit stores different configuration files corresponding to hydraulic brackets in different types, wherein the configuration fields record definitions of different output command ports; and the CPU processing module is used for receiving the control signal transmitted by the input module, receiving the type of the hydraulic bracket transmitted by the controller of the hydraulic bracket from the input module, analyzing a control command, reading the configuration file corresponding to the storage unit according to the type, and generating a corresponding control signal according to the read configuration file. By the electromagnetic pilot valve driver, the electromagnetic pilot valve group with different hydraulic bracket types can be automatically driven.

Description

technical field [0001] The invention relates to an electromagnetic pilot valve driver used in an electro-hydraulic control system. Background technique [0002] The problem of support and protection has always been an important issue that plagues coal mine safety production, output and efficiency. The emergence and development of the hydraulic support electro-hydraulic control system has fundamentally changed the underground working conditions, and laid the foundation for the rapid increase of high-efficiency and high-yield coal. Such as figure 1 A functional block diagram of the electro-hydraulic control system of a single hydraulic support is shown. [0003] The hydraulic support electro-hydraulic control system includes: [0004] Sensor 11, wherein the sensor may include a pressure sensor, a travel sensor, an infrared receiver, etc., and is used to collect various status information of the hydraulic support, such as the pressure of the support, the position and running...
