Embodiment
The invention provides a kind of simple in structure, control is convenient, reliability is high, cost is low subway wind valve controller.This system provides Equipment Foundations for further improving subway running environment.Below in conjunction with embodiment and accompanying drawing over the ground the iron winds valve control make a detailed description.
As shown in Figure 1, subway wind valve controller of the present invention includes SCM system 2, also is provided with: input system 1 is used for control signal and motor position feedback signal that SCM system is accepted control panel; Status display system 3 is used to show the residing position of air-valve, makes the staff in time understand the state of living in of air-valve; Motor driven systems 4 is used to control electric motor starting, stops and the motor forward and backward; Power supply 5 is used for providing power to SCM system and motor.
As shown in Figure 1, described input system 1 can receive control command signal and air-valve position signal, and control command comprises long-range and two kinds on the spot, in order to save their shared identical inlet opening of resource, changes exploitation control by mode and selects which kind of control mode; Be connected by the single-chip microcomputer pull-up resistor between external control signal and the single-chip microcomputer, but the single-chip microcomputer inlet opening is a low level when signal is arranged, otherwise is high level.
As shown in Figure 1, described SCM system 2 is cores of entire controller, and whole logical operations and control task are all finished by SCM system 2; After SCM system 2 receives command signal by input system 1, according to the residing position judgment motor of air-valve should be just to change or reverse, the control signal of SCM system 2 is opened or is turn-offed by optocoupler U5 oxide-semiconductor control transistors Q4, conducting and the shutoff of the on off state control relay K4 of Q4, relay K 4 conductings are rotated motor, if motor should reverse, 2 of SCM systems move without control relay K5, if motor should just change, then the signal of SCM system 2 is by the normally opened contact closure of optocoupler U4 and transistor Q5 control relay K5; Limit switch conducting when air-valve moves to specified position, Continuity signal passes to SCM system 2, SCM system 2 judgement motors should stop then to send instructions and to motor driven systems 4 relay K 4 disconnection motors be quit work, and state of a control display system 3 shows the position of air-valves.
