Description

A kind of point type ATP means of defences under degraded signal system
Technical field
The present invention relates to field of rail communication.
Background technology
When train and trackside communication loss, or system are transferred into backup mode, due to mobile unit can not know by The route mandate information of trackside equipment transmission is in the prior art, general using the fixed blocking pattern split by semaphore, department Machine carries out speed limit traveling under point type pattern according to ladder rate curve.Its shortcoming is：It is big in the following distance of point type train, department Machine is only capable of relying on experience, drives a vehicle, can not be driven a vehicle according to optimal continuous velocity controlling curve, therefore according to ladder rate curve It has impact on the operative performance of point type pattern.
The content of the invention
It is an object of the invention to provide point type ATP (train is automatic) means of defence under a kind of degraded signal system, subtract Small vehicular gap, and optimal continuous velocity curve is provided to driver.
Realizing the technical scheme of above-mentioned purpose is：
A kind of point type ATP means of defences under degraded signal system, under degraded signal system, the mobile unit of train passes through Receive the lock file that the transponder of each semaphore or beacon are sent on track and obtain point type mobile authorization, and according to route occlusion State, speed-limiting messages, emergency point, non-security stop, the target of front signal machine is calculated in principle and train position The distance of stop and distance objective stop, dynamic target velocity curve is then calculated in real time according to these information, and Target velocity curve negotiating man-machine interface is informed into driver.
In point type ATP means of defences under above-mentioned degraded signal system, after mandate route is cancelled, degraded signal system System uses delay route release to ensure that train is entering road-surface concrete.
In point type ATP means of defences under above-mentioned degraded signal system, driver confirms that front authorizes forbidding for terminal When semaphore becomes to allow signal due to follow-up route conditional grant, it can be confirmed by button, in parking or not parking In the case of the semaphore passed through with IATP (point type train automatic protection) pattern.
In point type ATP means of defences under above-mentioned degraded signal system, driver makes a dash across the red light after semaphore by mistake, train quilt Brake hard, stopped in protected section.
The beneficial effects of the invention are as follows：The present invention is provided under degraded signal system by interlocking of signals subsystem for train Personal distance using particular cell section as protection, reduces running interval, improves train operation efficiency.Meanwhile according to degradation The IATP target points and target range that signal system provides, the track relevant information in front can be known in advance.The optimal company of the present invention Continuous rate curve is to driver, compared with the staged rate curve of prior art, it is easier to driver driving, and improve train operation Efficiency, improve comfortableness.
Brief description of the drawings
Fig. 1 is the speed curve diagram that train passes through signal lamp in the present invention.
Embodiment
Below in conjunction with accompanying drawing, the invention will be further described.
Point type ATP means of defences under the degraded signal system of the present invention, when train and trackside communication loss, or system Backup mode is transferred into, degraded signal system provides a kind of effective degradation operation mode, combines continous way ATP patterns spy The point type ATP patterns of property.Train provides personal distance protection by interlocking of signals subsystem, and mobile unit is by receiving each semaphore Transponder or the lock file that sends of beacon obtain point type mobile authorization, and calculated according to route occlusion principle and train position Obtain state, speed-limiting messages, emergency point, non-security stop, target stop and the distance objective of front signal machine The distance of stop, then according to these information and combination orbital data (such as gradient, speed limit), dynamic target speed is calculated in real time Write music line, and target velocity curve negotiating man-machine interface is informed into driver, driver only needs to drive a vehicle according to prompting.Therefore, even if Under worst operation scene, train can still stop in protected section, after communication recovery, confirm by driver, IATP moulds Formula not parking can be upgraded to ATP patterns.
If when including different speed limits in train mandate route, it is as follows that mobile unit calculates target velocity：
Vtarget=Vcurrent+atarget*tcycle
If from train current location to authorize route terminal institute it is identical by the speed limit in region, mobile unit calculating target Speed is as follows：
Vtarget=Vcurrent+atarget*tcycle
Wherein,
agrade:The acceleration/deceleration that Slope grade comes；
Vcurrent:Train present speed；
tcycle:The process cycle time；
Sdistance_to_next_speed:To the distance of next target speed limit point；
Vnext_speed:Next target speed limit；
atarget:Aimed acceleration；
Vtarget:Target velocity.
If schedule workers, which cancel, authorizes route, degraded signal system uses delay route release to ensure that train exists Enter road-surface concrete.
If driver confirms that front authorizes the disable signal machine of terminal to become to allow letter due to follow-up route conditional grant Number when, can be confirmed by button, parking or it is not parking in the case of the semaphore passed through with IATP patterns.It is fair when reading Perhaps after signal, signal mobile unit is calculated so as to improve train target velocity and extend train target range.
The semaphore even if driver makes a dash across the red light by mistake, signal system will trigger train brake hard, ensure train in the red light that advances rashly Afterwards still can in protected section emergency, so as to avoid and front truck bump against.
As shown in figure 1, S1, S2, S3 are semaphore in figure.When train passes through semaphore S1, mobile unit detects should When answering device, target range is extended to next signal machine S2.In traveling process, S2 distant signal beacon T1 will not be detected Measure, because S2, which is red light, shows that red light curve forces train to be stopped before S2.As Train Approaching S2, S2, which is opened, allows letter Number, driver will press release button and require that train passes through semaphore S2 with the speed less than 15km/h.When S2 leading beacon T2 quilts When detecting, mobile unit allows driver to accelerate and provide next semaphore S3 target range.Curve represents speed in real time in figure Write music line.
Above example is used for illustrative purposes only, rather than limitation of the present invention, the technology people about technical field Member, without departing from the spirit and scope of the present invention, can also make various conversion or modification, therefore all equivalent Technical scheme should also belong to scope of the invention, should be limited by each claim.
