Abstract
The utility model discloses a kind of city rail vehicle test wire anti-overrunning system, including the multiple passive balises set along test wire, each passive balise inside write the positional information at itself relative test line both ends；Train is externally provided with the antenna for receiving passive balise signal；The control centre electrically connected with the antenna is provided with train；Train Control management system and brakes on train electrically connect with control centre.The utility model is not easy to be influenceed by environmental factor to the registration of train position, positioning result, reduces the dependence to driver's manual operation, and system functional reliability is high.
Description
Technical field
The utility model belongs to rail traffic vehicles control technology field, and more particularly to a kind of city rail vehicle test wire is anti-risk
Enter system.
Background technology
It is required to carry out pattern and routine test in test wire after the completion of city rail vehicle manufacture, because train need in test wire
Dynamic operation is wanted, therefore, it is necessary to prevents train from going out test wire end.
As shown in figure 1, traditional scheme is to set multiple terminals apart from direction board close to the position of end at test wire both ends
（It is general to set 2-3 apart from direction board）, distance that driver indicates according to direction board considers current of traffic and train
Speed is braked.Such a mode positions due to fully relying on artificial see apart from direction board to train, therefore positioning be present
The defects of inaccurate.With the development of technology, there is a kind of city rail vehicle anti-overrunning system using GPS positioning system, adopt
Braked with GPS location, then by driver according to orientation distance, current of traffic and train speed.Because GPS location is easy
Influenceed by environment such as weather, electromagnetic interferences, while the defects of positioning precision is poor, localized delivery delay is larger be present, therefore
It can not meet that city rail vehicle test wire is accurately positioned and round-the-clock debugging test demand.Meanwhile above two city rail vehicle is tested
The anti-protection method that advances rashly of line is completely dependent on driver and judges to carry out brake operating, driver also be present and forgets operation or maloperation and then lead
Train is caused to go out the risk of the test wire end.
The content of the invention
Existing city rail vehicle test wire anti-overrunning system position inaccurate, positioning result easily by such environmental effects, and
The judgement for fully relying on driver carries out brake operating, there is a possibility that to forget operation or maloperation.The purpose of this utility model exists
In for above-mentioned the deficiencies in the prior art, there is provided a kind of city rail vehicle test wire anti-overrunning system, to the positioning accurate of train position
Really, positioning result is not easy to be influenceed by environmental factor, reduces the dependence to driver's manual operation, and system functional reliability is high.
In order to solve the above technical problems, technical scheme is used by the utility model：
A kind of city rail vehicle test wire anti-overrunning system, its be structurally characterized in that including along test wire set it is multiple it is passive should
Device is answered, the positional information at itself relative test line both ends is write inside each passive balise；Train is externally provided with passive for receiving
The antenna of transponder signal；The control centre electrically connected with the antenna is provided with train.
By said structure, writing position information inside each passive balise, when experiment train passes through a certain passive response
During device, antenna will receive the positional information inside corresponding passive balise, decoded and read by control centre, so as to drive
The personnel of sailing can obtain positional information of the train on test wire, and then make correlated judgment or operation.Due to passive balise
The position signalling of inside write-in is accurate, and the signals transmission between passive balise and antenna is by such environmental effects,
Thus meet that city rail vehicle test wire is accurately positioned and round-the-clock debugging test demand.
Further, the Train Control management system on train and brakes electrically connect with control centre.
By said structure, list Control management system and send train current train traffic direction and train speed to control
Center processed, control centre's integrated location information, traffic direction and train speed judge whether train is run close to test wire end,
Decide whether to send brake signal again to brakes, so as to perform whole judgement and braking procedure automatically, reduce to driver
Think the dependence of operation.
As a kind of preferred embodiment, the passive balise is RF tag.
In the utility model, signal is write or read to passive balise inside and belongs to prior art.Meanwhile control
Center carries out simple comprehensive descision to several signals, and output drive signal falls within those skilled in the art when the condition is satisfied
Member can easily realize the simple program of its function using existing programmed method, and according to positional information, traffic direction and speed
Degree three decides whether that braking, brakes reception pumping signal send braking maneuver and also belong to prior art, therefore,
The utility model is not related to the improvement of program or method.
Compared with prior art, the utility model is not easy by environmental factor to the registration of train position, positioning result
Influence, reduce the dependence to driver's manual operation, system functional reliability is high.
Brief description of the drawings
Fig. 1 is traditional city rail vehicle test wire end protectiving scheme schematic diagram.
Fig. 2 is the utility model city rail vehicle test wire anti-overrunning system structural representation.
Wherein, 1 is passive balise, and 2 be antenna, and 3 be control centre, and 4 be Train Control management system, and 5 be braking system
System.
Embodiment
As shown in Fig. 2 an embodiment of the present utility model includes the multiple passive balises 1 set along test wire（It is passive
The quantity of transponder 1 is depending on the length and laying spacing of test wire）, the write-in itself of each inside of passive balise 1 is relative to be tried
Test the positional information at line both ends；Train is externally provided with the antenna 2 for receiving the signal of passive balise 1；Be provided with train with it is described
The control centre 3 that antenna 2 electrically connects.The passive balise 1 is RF tag.
Train Control management system 4 and brakes 5 on train electrically connect with control centre 3.
Embodiment of the present utility model is described above in conjunction with accompanying drawing, but the utility model is not limited to
The embodiment stated, above-mentioned embodiment is only schematical, rather than limitation, this area it is common
Technical staff is not departing from the utility model aims and scope of the claimed protection situation under enlightenment of the present utility model
Under, many forms can be also made, these are belonged within the scope of protection of the utility model.
