Background
Rail transit has become the most prominent means of long-distance transportation for our time. The method includes the steps that the use condition of a track section needs to be accurately monitored in the running process of the railway vehicle, when an occupied state of one track section is monitored, the track section is closed to prevent other railway vehicles from entering the track section, and when an idle state of one track section is monitored, the track section is opened to enable the track section to be normally used.
The main function of the track circuit is to continuously detect whether the section of the track circuit is occupied by rolling stock, and also to control signal devices or switching devices to ensure driving safety. The whole track system road network is divided into a plurality of block sections by proper distance, each block section is separated by a track insulation joint to form an independent track circuit, the starting point of each section is provided with a signal machine (color light type signal machine), when a train enters the block section, the track circuit immediately reacts and transmits the existing train passing in the section and the information that other trains are forbidden to enter to the signal machine, and at the moment, the signal machine positioned at the section entrance immediately displays the information that dangerous blocking is forbidden.
The axle counting device, also called a microcomputer axle counting device, is one of the devices for monitoring the use state of the track section, and judges whether the track section is occupied or not by monitoring the number of wheel pairs of the railway vehicle passing through between the axle counting points of the track section. The working principle of the axle counting device is that axle counting points are respectively arranged at the entrance and exit ends of a track section, the number of wheel pairs of the railway vehicles running into the track section and the number of wheel pairs of the railway vehicles outputting the track section are monitored, and then the occupation condition of the section is judged by comparing the number of the running-in wheel pairs and the running-out wheel pairs.
However, in practical use, it is found that misjudgment often occurs in monitoring of a track section by an axle counting device, and common performance includes a fault of a "red light band" occurring in an idle state of a track circuit, which is a common and frequent fault of a signal device and is one of main faults affecting driving safety.
