Problems solved by technology
[0003] However, the current hydraulic support control system is difficult to expand hydraulic components, sensors and complex functions due to the limitation of the number of interfaces and wiring methods, complicated wiring and the solidification of the electro-hydraulic control mode of a single support.
Moreover, although valve products based on bus control have been successfully applied in the fields of automotive electronics and construction machinery, the intrinsically safe and explosion-proof requirements of underground coal mines have set certain obstacles for the development of bus hydraulic components.

According to the scheme, an electromagnetic valve product capable of achieving bus control is provided, and an element basis is provided for a hydraulic support control system based on a bus.
Description
technical field [0001] The present application relates to the technical field of solenoid valve control, and in particular, to a bus-type solenoid valve. Background technique [0002] The hydraulic support electro-hydraulic control system is used to control the action of the hydraulic support of the underground working face, and cooperate with the shearer and scraper conveyor to realize automatic comprehensive coal mining. In recent years, with the deepening of the understanding of the coal mining process, the hydraulic support electro-hydraulic control system has been improved in terms of control procedures, electrical and added functions. [0003] However, the current hydraulic support control system is difficult to realize the expansion of hydraulic components, sensors and complex functions due to the limitation of the number of interfaces and wiring methods, complicated wiring and the solidification of the electro-hydraulic control mode of a single support. Moreover, al...
