All-digital hydraulic support control system based on double CAN buses and RS485 bus

The invention discloses an all-digital hydraulic support control system based on double CAN buses and an RS485 bus, which comprises a centralized control room and a plurality of support controllers, each support controller is respectively connected with a plurality of sensors, and the control system realizes support information display, data uploading and instruction issuing functions through the RS485 bus; transmission of control instructions is realized among the plurality of support controllers through double CAN buses. The two buses perform their own functions during working and do not interfere with each other; through the double CAN buses and the RS485 bus, the problems that an underground fully mechanized coal mining face control system is poor in anti-interference capability, incompatible in equipment interface, high in replacement difficulty and the like are solved, the performance is reliable, the anti-interference capability is high, the communication delay is low, and a solution is provided for al
