The following is a description of the principle and manner of implementing various pre-warning functions by the system.
1. Train route early warning
1) Principle of
And after the train receiving approach-the self-receiving approach is opened, sending early warning information according to different positions of the train from the station to the station track parking.

2. Shunting route early warning
1) Principle of
According to the characteristics of on-site shunting operation, after a shunting route is opened, a train does not always move at once, and the real early warning function cannot be achieved due to the fact that early warning information is sent too early. For the distinguishing processing of the locomotive with the STP vehicle-mounted equipment and the lead locomotive, the specific principle is as follows:
for the locomotive with STP vehicle-mounted equipment, early warning is carried out on operating personnel according to the accurate distance from the front end of the train to a working area; namely, for the locomotive equipped with the STP equipment, the system can obtain the real-time position in front of the locomotive (train) according to the position tracking result of the locomotive (train), further calculate the distance between the front end of the locomotive (train) and the early warning work area, and trigger the alarm when the positions of the front end of the locomotive (train) and the work area reach the design threshold.
For the lead locomotive, the operating personnel are warned according to the length of the route in front of the train and the occupation condition of the track circuit. For the lead locomotive, the system can track the train position according to the track circuit, the accurate position (which can not be accurate to meters and can only be accurate to a certain section) of the front end of the lead locomotive (train) can not be accurately obtained, and the relative position of the front end of the lead locomotive (train) and a working area can be obtained according to the occupation condition of the track circuit, for example, the distance X track sections, namely, the alarm is triggered.
2) Implementation mode
When the shunting route is opened, if the shunting route is a locomotive provided with STP vehicle-mounted equipment, calculating the distance of the front end of the train in real time, and performing early warning when the preset target distance is met; illustratively, the form is "shunting approach in the X-row direction, currently X meters from the X-ray signal". If the corresponding train is a lead locomotive, according to the condition of route opening, the occupation condition of a track circuit at the front end of the train is combined, and the early warning is carried out on the workers in the specific operation area; illustratively, the form is "X-direction shunting approach".
3. Swift current vehicle early warning
1) Principle of
And determining the push-to-peak operation condition in the station yard according to the acquired station yard information processing, and early warning the operators in a specific operation area by tracking the real-time position of the humped vehicle.
2) Implementation mode
The rolling vehicle has no corresponding open route, and the rolling vehicle information is not acquired, so that the rolling vehicle is tracked by the train position tracking module in the running process of the disassembled rolling vehicle, and the early warning module is used for early warning personnel in the corresponding operation area according to the occupation condition of the track circuit and the running process; illustratively, the form is "X row Direction Town near! "and the like.
According to the scheme of the embodiment of the invention, station indication information and shunting position information are acquired in one direction through the data transmission radio station, so that the repeated investment of basic equipment is avoided, the real-time tracking function of the position of the locomotive is realized, the running of existing equipment is not interfered, and the use efficiency of the existing equipment is improved. Meanwhile, the collected information is processed, the position of the locomotive in the station is tracked independently and in the whole process, and the voice alarm prompt can be performed on the operating personnel according to the position of the locomotive, the route opening characteristics and the locomotive operation condition and in combination with the distance condition of the corresponding operation area. A new means is provided for the in-station constructors and the protection personnel to master the in-station locomotive information, and the personal safety of the operating personnel is effectively guaranteed.
