Abstract

The invention discloses a communicator for a hydraulic-support electrohydraulic control system, which comprises a CAN (Controller Area Network) bus and a support controller connected to the CAN bus, wherein the support controller is used for implementing multiple serial communications, including CAN communication. The communicator disclosed by the invention has adaptability, integrates multi-function network communication modes, and provides great flexibility, practicality, diversity and reliability for the hydraulic-support electrohydraulic control system in the aspect of communication architecture.

Description

technical field [0001] The invention relates to the field of automatic control, in particular to a communication device for an electro-hydraulic control system of a hydraulic support. Background technique [0002] The electro-hydraulic control system of the hydraulic support is the most advanced control method of the hydraulic support at present. It integrates the technologies of machinery, hydraulic pressure, electronics, computer and communication network. technical product. It realizes the monitoring and control of the hydraulic support of the fully mechanized mining face according to the coal mining process, so that the hydraulic support and other mechanical mining equipment (such as coal shearers and scraper conveyors) can coordinate and operate in the best state, and give full play to the advantages of mechanical mining equipment. Productivity. The electro-hydraulic control system of the hydraulic support can not only automatically control the movement of the hydraul...
