Description
Technical field
The invention belongs to a kind of locomotive control method and device, is a kind of locomotive accident isolating controlling method and structure specifically, is meant fault of electric locomotive isolation control method and device especially.
Background technology
The glitch that some still are unlikely to influence traffic safety appears in electric locomotive unavoidably sometimes in operational process, this is referred to as " B " level or " C " level fault in railway systems.Wherein " B " level is minor failure, and this class fault can be isolated or operate with failure, and does not influence application, but must search and handle behind the Hui Ku; " C " level is scrappy glitch, and this class fault can be handled when the next one is repaiied journey.Therefore in the control system of locomotive, occurring still normally moving the general fault isolation system that in the control system of locomotive, all is provided with after " B " level or " C " level fault in order to ensure locomotive.When unusual and fault appear in locomotive equipment, but after fault isolation system will be the isolated fault kind according to the determined fault that occurs of vehicle mounted failure monitoring system, fault is carried out isolation processing.
What existing fault of electric locomotive isolated system adopted is that M/C excision switch is installed on low tension gas holder cabinet, when locomotive electric cad system circuit part goes wrong, the driver leaves driver's cab, manually will excise switch to the locomotive electric cad system chamber and get to " excision " position, in order to realize the temporary transient operation of locomotive by " automatically " position.The group operation of falling of locomotive microcomputer, LCU also is to reach the purpose of switching the A/B group by similar method manual operation switch to each cabinet.But this cover system is installed in the locomotive electric cad system chamber, and in the locomotive driving process, the driver must leave driver's cab ability complete operation, and it is on duty to have carried out single driver now, will certainly influence traffic safety.Isolate the excision switch if will be implemented in the driver's cab operation, common method is exactly that the disconnector on the low pressure cabinet is moved on on the driving position, and the two ends driver's cab all will go between.It is bigger to transform difficulty like this, and tens switches concentrate on the driving position, makes originally hard up driving position more crowded.Therefore necessaryly this is further studied and improved.
Summary of the invention
The objective of the invention is to: at the deficiency of existing fault of electric locomotive isolated system, a kind of device that can utilize the disconnector of driving position read-out operational order control electric panel room is proposed, and small and exquisite accident isolating controlling method and the device that adapts to existing locomotive finite space of structure.
Problem at the deficiency that has the fault of electric locomotive isolated system now, find by analyzing, realize present single driver needs on duty, the operation that needs to be positioned at some breakdown of equipment disconnectores between locomotive high-voltage chamber or machinery moves to driver's consing, exempts single driver some inconvenience on duty.Accelerate driver's operation simultaneously, shorten the driver for seeking the processing cycle that the switch particular location is brought.Therefore, the device that a cover can be ordered the automatic switchover fault by the driver should be installed.The driver operation order is realized by the original locomotive state read-out of driving position.The A/B of all like this disconnectores and microcomputer, LCU falls to organize operation and can operate on read-out, and the driver does not need to leave the excision work that driver's cab just can be finished failure circuit.Thereby guaranteed the reliability service of locomotive.
According to above-mentioned thinking, the objective of the invention is to be achieved through the following technical solutions.A kind of fault of electric locomotive isolation control method, comprise fault isolation control unit and driver's cab locomotive state read-out, its characteristics are: the fault isolation switch that utilizes driver's cab locomotive state read-out control electric panel room, original disconnector circuit incorporated into or sealed in the locomotive failure isolated location circuit, and by the super mediastinum of driver's cab locomotive state read-out from all buffer circuits of unit controls.
Concrete grammar is to incorporate in locomotive failure isolated location circuit or seal in the disconnector circuit, and adopt the RS485 communication modes to send the fault isolation order by read-out, after locomotive failure isolated controlling unit receives order, order is handled, the action of control corresponding relays, thereby the excision failure circuit makes locomotive continue operation; And operating result fed back to locomotive failure control unit inside by hardware, be presented on the color screen after the processing; And placing on record, so that driver's section of returning back maintenance.In order to improve communication quality, between 485 communication chips and 485 buses, increase photoelectric isolating circuit, be provided with on the bus can jumper connection the terminal matched resistance.For guaranteeing the reliability service of locomotive microcomputer, LCU, on the casing of locomotive failure isolated controlling unit, change-over swith is set, be used under the device proper failure condition, will fall to organize the original group of switch that power is given each cabinet.
The fault isolation control setup that the method according to this invention proposed is: comprise locomotive failure isolated location circuit and driver's cab locomotive state read-out, its characteristics are: incorporate in locomotive failure isolated location circuit or sealed in the disconnector circuit; Driver's cab locomotive state read-out is connected by control circuit with locomotive failure isolated location circuit, and is provided with the disconnector control contact on driver's cab locomotive state read-out.
Described locomotive failure isolated location circuit comprises that microcomputer control circuit, relay output circuit, reactive circuit, storage circuit, communicating circuit, display circuit and microcomputer organize circuit.Wherein, in microcomputer control circuit, incorporate into or sealed in the disconnector circuit.
Major advantage of the present invention is:
1, original disconnector circuit is incorporated into or sealed in the locomotive failure isolated location circuit.So just can control all buffer circuits by isolated location.
2, utilize the locomotive state read-out as man-machine dialog interface.To save driving position space and cost.
3, driver operation is carried out record, can inquire about.The driver that helps succeeding grasps situation and returns the maintenance of section back.
4, operating in driver's cab finishes.The driver does not need to go to the electric equipment compartment switch of operating machine again, and has strengthened the safety of locomotive driving.
