Description

Axle counting section state detection method, device, equipment and storage medium

Technical Field

The invention relates to the technical field of rail transit, in particular to a method and a device for detecting the state of an axle counting section, computer equipment and a storage medium.

Background

The CBTC (Communication Based Train operation Control system) system is a safe, high-reliability and high-stability Train automatic Control system Based on wireless Communication, is widely applied to urban rail transit, and is characterized in that a wireless Communication medium is used for realizing the bidirectional Communication between a Train and ground equipment, the traditional rail circuit is replaced by the medium for realizing the Train operation Control, the operation mode of the CBTC system is divided into a CBTC mode and an interlocking mode, the CBTC mode has the highest-level system operation and performance, and the interlocking mode is a standby operation mode for improving the operation safety when the CBTC system has equipment faults.

In the CBTC system, a ZC (Zone Controller) system is a ground core control device and is a necessary device for implementing mobile blocking. The real-time position of the train is obtained by the train through a speed measuring sensor on the locomotive and a transponder on a line, the transponder is arranged at a fixed position of the line, and the position of the train can be searched in a database when the train passes through one transponder, so that the accurate position of the train is obtained. The accurate position of the train is sent to the trackside equipment ZC system by the vehicle-mounted equipment in a wireless mode, and therefore communication of the train to ground equipment is achieved. After acquiring the train position in real time, the ZC system generates the movement authorization information of the train through comprehensive calculation, thereby realizing the safe operation control of the train.

The interlocking mode can be adopted under the condition that non-communication train operation or ZC system faults exist in a line, the position information of a train is judged by depending on occupation/clearance information of a detected track section, and the axle counting equipment is used as track section occupation inspection equipment and is widely applied to urban rail transit signal systems at home and abroad, so that the interlocking mode is of great importance in mobile block train operation and plays a more important role in the mobile block backup mode in safe train operation. However, under abnormal conditions, such as when the axle counting magnetic head is interfered or the axle counting device has a power failure, the axle counting section is not occupied by the train actually, but the axle counting device reports the occupation of the axle counting section, at this time, the ZC system limits the rear train from passing through the track section in order to ensure safety, and sets the occupation state of the axle counting section to be the non-communication train occupation state of the axle counting section, which will affect the train operation behind the axle counting section, affect the train operation efficiency, and cause the operation delay. In the prior art, when the fault of axle counting equipment is detected, the axle counting equipment is generally considered to fall to a safe side when the fault occurs, the output state is bound to be occupied, and the phenomenon of mistaken clearing of a track circuit due to poor shunting caused by sand-blown rust on a rail surface cannot occur. Therefore, each main manufacturer uses the axle counting equipment as a signal control system of the physical zone occupation detection equipment, and is only limited to the judgment of the detection misoccupation of the axle counting system, so that the condition that the detection misclear of the axle counting system is not considered in the judgment, and the problem of the train operation safety is caused.
