Abstract
Description
technical field
[0001] According to the International Patent Classification (IPC), the present invention belongs to the physical part, the signal device category, the signal device or the calling device; the instruction sending device; the small class of the alarm device, and the group technical field of electric transmission; specifically relates to a hydraulic support Head controller communication system. Background technique
[0002] The environment of the fully mechanized coal mining face is harsh, the number of hydraulic supports is large and the control is complicated. Compared with the unattended coal mining face, the comprehensive mechanized coal mining face commonly used at present has a low degree of automation, high work intensity, and poor safety. question.
[0003] In the comprehensive mechanized automatic coal mining working face, the processes of coal shearer, scraper conveyor and hydraulic support for lowering columns, moving frames, raising columns to suppo...

Embodiment Construction
[0021] The schematic diagram of the communication system structure of the terminal controller of the hydraulic support is as follows: figure 1 shown.
[0022] The invention includes a terminal controller, the communication bus of the terminal controller is provided with a frame controller, and the terminal controller is connected with an explosion-proof industrial control computer through an HXSP-2108B converter.
[0023] The terminal controller centrally controls all the inter-rack controllers, and the communication mode adopts the master-slave mode; the default communication mode of the terminal controller is the sending state, and the default communication mode of all inter-rack controllers is the receiving state.
[0024] The rack controller can perform specific actions only after receiving the control signal sent by the end controller. The communication between the terminal controller and the explosion-proof industrial control computer adopts the master-slave mode. The d...
