Design of centralized control system for hydraulic supports on fully-mechanized coal mining face

In view of problem of low automation degree of current electro-hydraulic control system for hydraulic supports, a centralized control system for hydraulic supports on fully-mechanized coal mining face was designed, designs of hardware and software of the system were introduced, and realizing process of centralized control for hydraulic supports was also expounded. The test results show that the system can realize centralized control of hydraulic supports, and has performances of stable field communication and high real-time, which can meet actual requirement of coal mine production.
