Abstract

The invention discloses a hydraulic support end socket electro-hydraulic controller in which a liquid crystal display unit is connected with a parallel data bus P3 port of an MCU and a control bus pin; a keyboard scanning unit is connected with a scanning signal output bus P5 port of the MCU, an input signal receiving pin and an interrupt signal receiving pin; a drive circuit unit is connected with a buzzer control pin of the MCU, an alarm lamp control pin and a power light control terminal 3.3V power; an RS-485 interface unit is connected with an asynchronous serial communication pin and a read / write control pin of the MCU; a power supply unit is respectively connected with the corresponding power terminals of the MCU unit, the liquid crystal display unit, the keyboard scanning unit, the drive circuit unit and the RS-485 interface unit; and the JP1 port of the keyboard input unit is connected with a JP1 port of the keyboard scanning unit. The invention can control corresponding functions of the hydraulic support by a centralized control program or the hydraulic support end socket electro-hydraulic controller according to the position of the coal cutter, thus realizing safe and reliable automatic control on the hydraulic support at the coal face.

Description

technical field [0001] The invention relates to a controller of an underground hydraulic support in a coal mine, in particular to a terminal electro-hydraulic controller for centralized control of a hydraulic support in a coal mining face. technical background [0002] At the end of the 1980s, the world's first double-head automatic plow was put into use in the United States, and then several more were used in Germany, realizing the automation of coal mining and greatly improving safety. [0003] In the early 1990s, the PM4 hydraulic support electro-hydraulic control system launched by the French DBT company can automatically move the frame and push the scraper conveyor. Wall mining, but the production efficiency is worse than the shearer. [0004] In the past two thousand years, the German DBT company has cooperated with domestic scientific research institutes and coal machinery factories to develop comprehensive automatic thin coal seam mining equipment, which is used for...
