Fig. 1 is control device schematic diagram of the present invention.
Embodiment
It is further detailed to the embodiment work of the present invention by the description to optimum embodiment below against accompanying drawing
Thin explanation.
Such as figure, a kind of hydraulic support control device, include the control system that multiple control units form, each control unit
Correspond to and control a hydraulic support, communicated to connect between the control unit in control system by CAN, same control system
Interior control unit is powered using identical power supply, is connected between control system by isolating coupler.Same control system
Generally 4 control units, 4 frame hydraulic supports are controlled, the electrical equipment such as control unit in the control system uses same electricity
Source is powered, and the control unit in control system is communicated to connect by CAN communication mode, due to hydraulic support be all it is multiple into
Row uses, therefore in multiple control systems, the communication between control system realizes isolation communication by isolating coupler.Each
Control system is when providing power supply, and using intrinsic safety type power supply, each power supply is equipped with a power coupler, passes through power coupler
Powered for the control unit in control system, it is achieved thereby that electrical isolation and communication isolating.
Control unit includes driver, hand-held control terminal, electromagnetic pilot valve group, holds control terminal connection driver,
Driver sends control signal to electromagnetic pilot valve group, for controlling electromagnetic pilot valve group.It can be sent out by hand-held control terminal
Go out control signal into driver.
Driver includes single-chip microcomputer, drive signal amplifying circuit, CAN communication unit, and single-chip microcomputer is used to receive hand-held control
The control signal of terminal, drive signal amplifying circuit are used to control electricity after being amplified according to the drive signal sent of single-chip microcomputer
Magnetic pilot valves；Single-chip microcomputer is connected with CAN communication unit, for being communicated to connect with other drivers.Hand-held control terminal is sent
Control signal be sent to single-chip microcomputer after, single-chip microcomputer is to that can pass through CAN communication unit forwards to other drivings after signal transacting
In device, or send drive signal and be sent into after drive signal amplifying circuit carries out signal amplification in electromagnetic pilot valve group, so as to
Control hydraulic support corresponding to this control unit.As for other drivers are forwarded to, here can in each driver monolithic
A hydraulic support sequence number is stored in machine, sequence number and hydraulic support correspond, and hold control terminal and select corresponding sequence number, send
Enter into driver, the sequence number that single-chip microcomputer stores according to it in driver carries out correspondingly, being mutually simultaneously emitted by driving control signal, no
