Description
Technical field
The invention belongs to the city rail vehicle design scheme, relate generally to a kind of automatic reset system and method that is used for door control units of mass transit vehicle door.
Background technology
The current reset schemes that is used for door control units of mass transit vehicle door is mainly hand-operated forced power-off restoration scheme.In the prior art, on each the joint car in train the power supply of two-way door control unit is set, wherein one the tunnel gives the left side door control unit, the right side door control unit is given on another road, is provided with an one pole automatic switch on the way whenever, is used to control this side door control unit power supply.When crashing appears in artificial judgement door control unit, artificially force this road door control unit power supply of power-off restoration to realize resetting.This artificial judgement forced resetting method has caused problems such as efficient is low, maintenance workload is big undoubtedly.
Summary of the invention
Defective to above-mentioned prior art existence; The present invention aims to provide a kind of automatic reset system and method that is used for door control units of mass transit vehicle door; Automatically reset through control unit for vehicle (cellular logic) judgement, reduced labour intensity, improved operating efficiency.
The technical scheme that the present invention takes is; A kind of automatic reset system that is used for door control units of mass transit vehicle door; It is characterized in that; Comprise the door control unit power supply train-line that connects full train and be arranged on the said power supply train-line, and by door control unit, reset relay, one pole automatic switch, digital module and the control unit for vehicle of its power supply; Every joint car is provided with two reset relays corresponding respectively with the left and right sides door control unit; Wherein the auxiliary constant close contact of one pole automatic switch, reset relay and door control unit are connected into a door control unit branch road, parallelly connected with other door control unit branch roads again being articulated on the said door control unit power supply train-line; Wherein reset relay is also connected with control unit for vehicle through digital module, constitutes door control unit reset instruction loop; Said control unit for vehicle is connected through bus with door control unit.
Simultaneously, in order to show reset mode in real time, said control unit for vehicle also is connected with man-machine interface.
Simultaneously; The present invention also provides a kind of auto-reset method that is used for door control units of mass transit vehicle door; It is characterized in that, comprise the steps: when the control unit for vehicle that is connected communication with door control unit is not received door control unit information in predetermined period, judge that door control unit crashes; Control unit for vehicle sends command signal; Control is sent high level signal with the corresponding output channel of the digital module that the door control unit that takes place to crash is connected in series; And keep scheduled time t; The reset relay that corresponding output channel with digital module is connected gets electric, and the auxiliary constant close contact that said reset relay is serially connected on the said door control unit branch road breaks off, and corresponding door control unit is in power failure state; Through behind the scheduled time t; The high level of the corresponding output channel output of digital module transfers low level to, and reset relay is controlled by low level signal, is power failure state; The auxiliary constant close contact of reset relay is in closure state; Door control unit be in electricity condition, door control unit powers on and restarts, and realizes the control that resets of door control unit.
Based on said structure, operating principle of the present invention is described below: owing on every joint car left and right sides car door door control unit is arranged, therefore corresponding with it, the present invention is provided with the reset relay of two reset relays as the left and right sides car door door control unit of each joint car.When the control unit for vehicle judgement has door control unit to crash; The digital module that control is attached thereto sends high level and low level; Make the gate reset relay keep certain hour electric to the dead electricity process, guarantee door control unit on this reset relay place door control unit branch road be in the electric reset mode that arrives electricly again to dead electricity.When door control unit need reset, reset relay was in electricly and then arrives power failure state; When door control unit was in operate as normal (be not in and reset) state, reset relay was in power failure state all the time, does not influence the operate as normal of car door door control unit.The output of the high-low level of control unit for vehicle control figure module channels, and can be with the reset mode information of the car door door control unit machine interface display of making a gift to someone.On whole train, arrange a car door door control unit power supply of DC110V train-line, and the auxiliary constant close contact of said one pole automatic switch, door control unit and reset relay is cascaded and is connected in parallel on the train-line.The one pole automatic switch is used for to car door door control unit current supply circuit protections such as overcurrent being provided.When control unit for vehicle detected door control unit and is in the deadlock state, the method for generally taking was: control unit for vehicle is linked to each other through bus with door control unit and through its communication, and whether control unit for vehicle can detect the signal that door control unit sends normal.If in the network transmission cycle of maximum, control unit for vehicle receives that the data message that door control unit sends does not change, and shows that fault has appearred in door control unit.If promptly control unit for vehicle can not receive door control unit information in some cycles, judge that door control unit crashes.Control unit for vehicle is given reset relay certain hour high level signal through the digital module passage; The reset relay corresponding with door control unit got; The auxiliary constant close contact of reset relay breaks off, and corresponding door control unit is in power failure state, passes through digital module passage output low level through control unit for vehicle behind the certain hour; Make reset relay be in power failure state; The auxiliary constant close contact of reset relay is in closure state, door control unit be in electricity condition, door control unit powers on and restarts.
Car door door control unit automatic reset system that is used for city rail vehicle according to the invention and method have overcome to be needed when door control unit crashes artificially to judge that the back forces manually to turn-off the one pole automatic switch and realize the shortcoming that door control unit resets; Owing to arranged train-line; And be provided with reset relay and digital module by its power supply; Only need when control unit for vehicle judges that door control unit crashes, just can realize that door control unit automatically resets; Thereby can avoid artificially judging the risk that door control unit crashes by accident, significantly reduce judgement time and workload, help providing vehicle reliability.
