Abstract
The invention discloses an ATPM/WSP operation method without wheel diameter verification. The method includes the steps that when a signal vehicle-mounted device is powered off and restarted or loses the wheel diameter, a vehicle-mounted controller uses a nominal wheel diameter value for speed calculation so as to determine an estimation position of a train, and meanwhile, the vehicle-mounted controller calculates the maximum uncertainty deviation brought by the nominal wheel diameter value and compensates for the maximum uncertainty deviation; and when the wheel diameter is not calibrated, the vehicle-mounted controller supervises the maximum speed of the train in an ATPM/WSP mode, and the train runs at the limited speed 5% lower than the maximum running speed obtained when the wheel diameter is successfully calibrated. By the adoption of the method, the operation efficiency of the non-wheel-diameter train is improved, and the train is allowed to run in a signal controlled mode at the speed close to the normal operation limited speed under signal protection.
Description
Technical field
The present invention relates to field of track traffic.
Background technology
Signalling arrangement determines train position using the real-time train wheel footpath calculating, to reach pinpoint purpose.When
When signal mobile unit power-off restarting or loss wheel footpath, mobile unit cannot obtain exact position.In the prior art, often
Using degradation artificial mode (such as rmf pattern), to limit low speed operation (such as 25km/h), carry out safeguards system safety.
Due to being launched installation site and the distance limit of equipment by the other wheel footpath of track, driver may need to run at a low speed relatively
The long time could reacquire train wheel footpath, setting up controlled mode, thus improving speed, therefore have impact on efficiency of operation.And
And if under manually uncontrolled pattern, the protection content of signal is less than controlled mode, now to driver and central schedule person
Operation requirement can accordingly improve, and the restrictive condition of system is accordingly increased.
Content of the invention
It is an object of the invention to provide the atpm under a kind of no wheel footpath verification is (under time interval between to trains system monitor
Pilot steering pattern)/wsp (the point type driving model under in-orbit other systematic protection) method for running, improves the fortune of no wheel footpath train
Battalion's efficiency is it is allowed to train protects down train with signal controlled mode and close to the speed of normal operation speed limit in signal.
The technical scheme realizing above-mentioned purpose is:
A kind of atpm/wsp method for running under no wheel footpath verification, comprising:
In signal mobile unit power-off restarting or loss wheel footpath, Vehicle Controller carries out speed using nominal wheel footpath value
Calculate to determine train estimated position, Vehicle Controller does not know deviation by calculating the maximum that nominal wheel footpath value is brought simultaneously,
And uncertain deviation compensates to this maximum；
When wheel footpath is not calibrated, Vehicle Controller supervises train maximal rate under atpm/wsp pattern, and with than wheel
During the successful calibration of footpath, the restriction speed of maximum operational speed low 5% is run.
In the atpm/wsp method for running under above-mentioned no wheel footpath verification, described nominal wheel footpath value is maximum wheel footpath value
Half with minimum wheel footpath value sum.
In the atpm/wsp method for running under above-mentioned no wheel footpath verification, described is brought to using nominal wheel footpath value
Maximum do not know the computational methods of compensation of deviation and be:
The invention has the beneficial effects as follows: the present invention, before position set up by train but wheel footpath is not calibrated, allows in system
Under rate limitation protection, signaling system still allows train to enter atpm/wsp pattern, rather than only allows uncontrolled pattern fortune
Battalion, improves the convenience of the no efficiency of operation of wheel footpath train and driver/central schedule person's operation.
Specific embodiment
Atpm/wsp method for running under the no wheel footpath verification of the present invention, comprises the steps:
In signal mobile unit power-off restarting or loss wheel footpath, Vehicle Controller carries out speed using nominal wheel footpath value
Calculate to determine train estimated position, nominal wheel footpath value is central diameter wheel footpath value, as maximum wheel footpath value and minimum wheel footpath value sum
Half.Such as when maximum wheel footpath value is 840mm, and minimum wheel footpath value is 770, this central diameter wheel footpath value is 805mm.
Simultaneously as nominal wheel footpath not accurate wheel footpath, there is error in the train position that Vehicle Controller calculates gained, this
When system need train use not calibrated wheel footpath run duration, extra compensation is carried out to the uncertain deviation of position.Pass through
Calculate the uncertain deviation of maximum that nominal wheel footpath value is brought, calculated in the possible position of train, and true to this
Determine deviation to compensate.The computational methods of the described compensation that the maximum brought using nominal wheel footpath value is not known with deviation
For:
When wheel footpath is not calibrated, Vehicle Controller supervises train maximal rate it is contemplated that taking turns under atpm/wsp pattern
Speed that the possible error area in footpath is formed is uncertain, now allow with than wheel footpath successful calibration when maximum operational speed low
5% restriction speed is run.Such as train operation speed per hour is 80km/h, and when wheel footpath is not calibrated, it is 76km/ that signal allows speed per hour
h.
Above example is used for illustrative purposes only, rather than limitation of the present invention, about the technology people of 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 also should belong to scope of the invention.
