Description
Technical field
The utility model relates to field of track traffic, do system more particularly, to a kind of tramcar route mistake proofing.
Background technique
Modern tram is as a kind of novel vehicles, because of its feature of environmental protection, comfort, punctuality and investment
It is small, it is the features such as construction period is short, just fast-developing at home.In order to improve efficiency of the tramcar by Cha Qu, in conjunction with interlocking
The characteristics of relationship and modern tram, needs to trigger route in advance and handle when Train Approaching branches off area, to improve rail electricity
The efficiency that vehicle passes through Cha Qu.According to Operational requirements, triggering for tramcar route had both required control centre can be according to fortune
Row plan and vehicle location automatic trigger, and require in the case where no control centre, it is local it is vehicle-mounted can according to plan or
Person driver presses selection entry direction and triggers route by RR beacon.Due to site environment complexity, and exist simultaneously a variety of do
The approach of route is managed, so a possibility that mistake does route is increased, and mistake does route and belongs to serious event in rail traffic
Barrier, needs to avoid in time.
It prevents route mistake from doing device in existing rail traffic and is generally placed at station, by TDCS device and microcomputer connection
The mistake proofing of console implement of interruption function is installed on locking device and does function.Railway route entry handle all be by station or control centre into
Row is handled or vehicle-mounted interlocking carries out route according to the location information of tramcar and handles.But for tramcar,
In the case where there is no control centre, uses RR beacon to carry out route and handle, belong to point type communication.Route life is handled issuing
Enable the position of (RR beacon) and actually enter Cha Qu position between there are one section of blind areas, between this section of distance there are mistake do into
A possibility that road, typical mistake, which does scene, to be had:
1, since the defect of control centre's logic is the route or rail that current tramcar establishes mistake in advance
Electric car temporarily has modified route plan after route triggers well in advance；
2, when the first train issues after route handles order by RR beacon, item is established since interlocking does not have route
Part handles route so failing, and the first train waits route to establish before being parked in route signal, and the second train passes through at this time
The route that RR beacon issues other directions handles order, and route is handled in interlocking, leads to the route that mistake has been opened for the first train
Signal.
For both typical scenes, goes to solve this problem at present there is no the technology of comparative maturity, can only rely on
Tramcar driver judges that there are security risks.
Modern tram during main track is run, using beacon or induction coil carry out control command issue or
Person positioning, it is this based on point type communication control mode, signal control be it is discrete, delay, there are it is missent can
It can property.It, will be entire vehicle-mounted in conjunction with train position by vehicle-mounted interlock device currently based on the train control system of truck traffic
The route of interlocking is divided into the different stages and is protected.Protection for point type rank Train safety, main use wirelessly connect
The method entered is protected when platform is abnormal event, can notify to have passed over the Road defence semaphore before platform in time
Train.These current techniques all can not handle Road defence applied to the main track tramcar communicated based on point type.
China Patent No. CN202180836U discloses a kind of station train reception and departure route mistake proofing and does prompt system, it includes
Logical processor, audio alert suggestion device, operating terminal machine and station microcomputer detecting system, wherein the logical processor
The station microcomputer detecting system is connected, the operating terminal machine connects the logical processor, the logical processor connection
The audio alert suggestion device.It is artificial wrong with design science, reduction that prompt system is done in the station train reception and departure route mistake proofing
Accidentally, the advantages of improving station operational paradigm.But the utility model also needs Platform attendant to pass through operating terminal machine typing train
Plan, does not establish truck traffic, when its logic processor is defective or route is waited to establish for two trains, indefinite energy
No effective progress mistake proofing is done.
