Background technology
Mostly current subway train is the battery-driven car group adopting, the subway train of typical 6 joint marshallings is made up of 4 motor-cars and two trailers, the subway train of 6 joint marshallings is divided into two unit (three of every unit car) conventionally, on motor-car in the middle of each unit, there is a set of pantograph, for train high powered.At present, what the current collecting bow lifting control system on subway train adopted is the train rigid line that runs through full train, adopts train rigid line can strengthen train manufacturing cost, also can cause the puzzlement in wiring simultaneously and strengthen the weight of train.Along with developing rapidly and the continuous maturation of Train Control and monitored control system of network communication field, the lifting that obviously utilizes train network system controlling software to control pantograph has been a kind of trend and will have become main flow in the future.
Summary of the invention
Technical matters to be solved by this invention is, overcomes the above-mentioned deficiency of prior art, and a kind of subway train pantograph control method based on train network system is provided.
In order to solve above technical matters, the subway train pantograph control method based on train network system provided by the invention, is characterized in that train network system remote input/output module is connected with pantograph control system, and the control method of pantograph is as follows:
The first step, receive the operational order of current collecting bow lifting when train network system Central Processing Unit (CPU), if now train network system Central Processing Unit (CPU) regulation does not participate in the control of lifting bow, transmit this instruction to pantograph control system by the remote input output module of train network system, judge voluntarily and carry out lifting bow by pantograph control system; Otherwise go to second step;
If any is activated in second step emergency stop button or train sleep relay or workshop power supply, all pantographs of time delay 2s mandatory down notify all tractor equipments and all accessory equipments; If all do not activated, go to the 3rd step;
If bow falls in the 3rd step this locality, instruction activates, time delay 2s carries out this locality and falls and bend and notify local tractor equipment, judge that far-end falls bow instruction and whether activates simultaneously, if bow falls in far-end, instruction also activates, time delay 2s execution far-end falls and bends and notify all accessory equipments, if bow falls in far-end, instruction does not activate, and does not carry out the operation of lifting bow, if instruction does not activate if bow falls in this locality, this locality, go to the 4th step;
If the local rising bow instruction of the 4th step does not activate, do not carry out the operation of lifting bow; If local rising bow instruction activates, go to the 5th step;
If all train accessory equipment AC contactor all do not have closure on the 5th step train, carry out local rising bow operation; If have any one train accessory equipment AC contactor closure, go to the 6th step;
If the 6th step train has high pressure to exist, carry out local rising bow operation; If train does not have high pressure, do not carry out local rising bow operation, and driver display unit carries out corresponding prompting.
The present invention further improves and is:
1,, in described the 6th step, if train does not have high pressure, driver display unit shows the information about " may with carry a rising bow ".
2, the operational order of described current collecting bow lifting is sent to train network system Central Processing Unit (CPU) by the corresponding button on driver operation driving position or click driver display unit.
Sending of current collecting bow lifting instruction of the present invention can be by the pantograph master cock on driver's read-out or on driving position, then instruction is transferred to the Central Processing Unit (CPU) of train network system by driver display unit (while operation on driver display unit) or remote input output module (while operation on driving position), Central Processing Unit (CPU) carries out sending corresponding control command to traction ancillary system and pantograph control system after logistic diagnosis in conjunction with states such as related system equipment, controls the lifting of pantograph.
The present invention utilizes the lifting of network system software control pantograph, the trouble that can reduce train manufacturing cost, connects up and bring.This method possesses skills, and reliability is high, equipment cost is low, realize the features such as simple.
Brief description of the drawings
Fig. 1 is the inventive method diagram of circuit.
Detailed description of the invention
For making object, technical scheme and the advantage of the embodiment of the present invention clearer, below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is clearly and completely described.
Be illustrated in figure 1 the inventive method diagram of circuit.The subway train pantograph control method of the embodiment of the present invention based on train network system, hardware aspect, train network system remote input/output module is connected with pantograph control system, and the control method of pantograph is as follows:
The first step, receive the operational order (operational order of this current collecting bow lifting by driver operation driving position or click the corresponding button on driver display unit be sent to train network system Central Processing Unit (CPU)) of current collecting bow lifting when train network system Central Processing Unit (CPU) (VCU), if now train network system Central Processing Unit (CPU) regulation does not participate in the control of lifting bow, transmit this instruction to pantograph control system by the remote input output module of train network system, judge voluntarily and carry out lifting bow by pantograph control system; Otherwise go to second step;
If any is activated in second step emergency stop button or train sleep relay or workshop power supply, all pantographs of time delay 2s mandatory down notify all tractor equipments and all accessory equipments; If all do not activated, go to the 3rd step;
If bow falls in the 3rd step this locality, instruction activates, time delay 2s carries out this locality and falls and bend and notify local tractor equipment, judge that far-end falls bow instruction and whether activates simultaneously, if bow falls in far-end, instruction also activates, time delay 2s execution far-end falls and bends and notify all accessory equipments, if bow falls in far-end, instruction does not activate, and does not carry out the operation of lifting bow, if instruction does not activate if bow falls in this locality, this locality, go to the 4th step;
If the local rising bow instruction of the 4th step does not activate, do not carry out the operation of lifting bow; If local rising bow instruction activates, go to the 5th step;
