Description

Technical Field

[0001] The invention relates to a rail transit signal system, and in particular to a train route control method, equipment and medium based on electric anti-slipping. Background Art

[0002] Electric anti-slip equipment is used to fix the position of trains and prevent them from slipping, and is used in freight stations and marshalling yards. Anti-slip equipment is usually independent of the train dispatching command system, the centralized dispatching system or other traffic signal control systems, and the two systems cannot be linked; the traditional traffic control system uses manual anti-slip marking or manual anti-slip marking on the line board; there are problems such as untimely marking and withdrawal of anti-slip, easy mistakes in marking, inability to link with route handling or low degree of automation, and it is completely dependent on manual marking, which increases the workload of users. It is inevitable that manual mis-marking of anti-slip and wrong route handling will occur, posing safety hazards.

[0003] After searching, Chinese patent publication number CN118744745A discloses a railway arrival and departure line parking device anti-slip control system and method, the system includes an approach system, which is used to obtain approach information and send it to the control logic unit; trackside video equipment, which is set at both ends of the track, is used to obtain track video information and send it to the control logic unit; axle detection equipment, which is arranged at intervals on the track where the parking device is located, is used to obtain axle detection information and send it to the control logic unit; the control logic unit is used to automatically control the action of the parking device on the arrival and departure line through a fully electronic trackside control unit based on one or more of the approach information, track video information, and axle detection information when receiving a train on the arrival and departure line, sending a train on the arrival and departure line, and shunting operations on the arrival and departure line. However, the existing patent does not effectively combine the electric anti-slip equipment with the train approach management.

[0004] Therefore, in view of the current situation of insufficient technical protection at stations, it is necessary to automatically obtain and set the anti-skid status of the track through technical upgrades, so as to carry out automatic card control entry processing, improve the safety of station receiving and sending trains, and enhance the station's safety management and control capabilities, which has become a technical problem that needs to be solved. Summary of the invention

[0005] The purpose of the present invention is to overcome the defects of the above-mentioned prior art and to provide a train route control method, equipment and medium based on electric anti-skid.

[0006] The purpose of the present invention can be achieved by the following technical solutions:

[0007] According to the first aspect of the present invention, a train approach control method based on electric anti-slipping is provided, which obtains the status of electric anti-slipping equipment on each track of the station in real time. When processing train approach or shunting approach, it checks whether the status of the anti-slipping equipment meets the approach processing conditions. The approach can be triggered only when the status of the anti-slipping equipment meets the approach processing conditions. Otherwise, a pop-up window will prompt that there is an anti-slipping equipment on the track and the approach is not allowed.

[0008] As an optimal technical solution, the method provides a manual intervention function. When access cannot be processed due to anti-slip card control due to communication interruption, and on the premise of manual confirmation that the anti-slip device status allows access, manual forced access is supported.

[0009] As a preferred technical solution, after obtaining the status of all electric anti-skid devices in the station, the method synchronously displays the status of the track anti-skid devices on the station yard map.

[0010] As a preferred technical solution, when displaying the status of the track anti-skid device, the anti-skid device number can be displayed, and different anti-skid states can be distinguished by color.

[0013] As an optimal technical solution, the method designs safety control rules for track anti-slip access. When handling train and shunting access, the track anti-slip safety control rules are checked, and the access is only processed if the handling conditions are met.

[0014] As a preferred technical solution, the method includes the process of obtaining and setting the status of the track anti-slip device, and controlling the route handling process according to the status of the anti-slip device.
