In this embodiment, the allow pass message may be a message that allows the train to pass through the zone in which the active transponder is located. It should be noted that the transponders provided in the throat area are newly added transponders for the set route, and the normal passing of the train cannot be affected except for the set route, and the passing-permitted message is sent to control the normal running of the train.
For example, as shown in fig. 3, the station is a station with track code, and in order to solve the parking problem caused by too long distance of the throat area update track section packet information of the route from XN to X3, XN to XI, XN to X2, an independent active transponder group BSZ12G is added in the section where the route passes, and the track section packet is updated according to the corresponding route. Only when the corresponding lateral vehicle receiving route is established and the signal is opened and the section where the transponder is located is the route locking, the active transponder in the throat area is controlled by the train control center to send a route message. When the section where the transponder is located is unlocked, the throat area active transponder redirects the allowed passage message.
Meanwhile, in order to solve the braking problem caused by overlong code-free sections of the throat area in the partial monitoring mode during the lateral line transfer and departure of SI to S12, the BSZ12G is additionally provided with a route message for transmitting the route departure direction. After the SI to S12 departure approach is processed, the train is launched in a partial monitoring mode from the stock track without the outbound active transponder, and the vehicle-mounted equipment is converted into a full monitoring mode for controlling the train after passing through the active transponder BSZ12G in the throat area, so that automatic frequency conversion is realized. Only when the lateral line-transferring departure route (SI to S12) is established and the signal is opened and the section where the transponder is located is the route locking, the throat area active transponder BSZ12G sends line data according to the route direction, and the line data comprises track section information, transponder link information, running speed limit information and the like. And after the section of the active transponder in the throat area is unlocked, stopping sending the message by the active transponder in the throat area.
