Description

TECHNICAL FIELD

[0002] The railway technical management regulation No. 301, hereinafter referred to as the technical regulation 301, is a red line for the safety production of the station, which mainly regulates the safety, stability and comfort principles of the train in operation, and the prevention and treatment measures of the train accident. Once the shunting operation violates the technical regulation 301, the shunting signal rushes to the passenger train, which is likely to cause a more serious train accident and endanger the safety of passengers. The specific content of the railway technical management regulation No. 301 is as follows: when the passenger train is received and sent, the line without separation equipment or derailers from the received and sent train route is not allowed to be shunted to the direction that can enter the received and sent train route.

[0003] According to the statistics, as of the end of 2023, the proportion of CTC stations is about 45.9%, the proportion of TDCS stations is about 37.4%, and the proportion of interlocking stations is about 16.7%.

[0074] S35, check whether the locked section set of the passenger train route in the route set contains the turnout, if yes, it indicates that the shunting route and the passenger train route form the 301st conflict of the railway technical management regulation;

[0075] S36, end.

[0076] As Figure 3 ​The diagram shows a schematic of passenger train route processing. Passenger train K15 is processing the XII-S departure route. Signal XII is given a train permission signal, and the XII-S departure route is stored in the route set. The route type is a passenger train route, the starting signal is XII, the locked section set includes turnouts 2, 4, and 6, and the train number is K15.

[0077] like Figure 4 The diagram illustrates a conflict arising from the handling of shunting routes as defined in Technical Regulations 301. Shunting locomotive 0088 handles shunting route D1-D3. Signal D1 issues a shunting permission signal, and shunting route D1-D3 is added to the route set. The route type is shunting route, the starting signal is D1, and the locked sections include turnouts 1 and 3. The route set already contains passenger train route XII-S. It is necessary to check whether shunting route D1-D3 conflicts with passenger train route XII-S as defined in Technical Regulations 301. According to... Figure 2 The process shown starts with turnout 3, the last locked section in the D1-D3 shunting route, as the search starting point. Turnout 5 is found in the down direction. Since it passes through turnout 5 in the reverse direction, turnout 5 is in the reverse position. The search continues until IIG is found. When turnout 2 is found, it is determined that the current state of turnout 2 is locked and it belongs to the set of locked sections in the XII-S passenger train route. Therefore, the D1-D3 shunting route and the XII-S passenger train route constitute a conflict with Technical Regulations 301.
