[0002] In the railway transportation system, the rationality of the section operation gap (i.e. the time interval between two consecutive trains in the same section) is closely related to the train safety and transportation efficiency. At present, the monitoring of the gap mainly relies on the manual interpretation of the train diagram by the dispatchers, which has the following obvious defects: 1. Low monitoring efficiency: the dispatchers need to monitor the train operation of multiple sections at the same time, manually calculate and judge whether the gap is reasonable, which is of great work intensity and is easy to miss due to fatigue or negligence; 2. Subjective judgment standard: there are individual differences in the understanding and grasp of the safe threshold of the operation gap by different dispatchers, and there is a lack of unified and quantitative judgment standard, which is poor in decision consistency; 3. Insufficient early warning timeliness: manual monitoring is difficult to timely capture the gap abnormalities caused by dynamic adjustment of the operation plan, and often deals with the problems after they appear or occur, which is weak in prevention ability; 4. Lack of data analysis capability: there is a lack of systematic recording and statistical analysis of historical operation gap data, which is difficult to summarize the rules and locate the high-frequency problem sections, and cannot provide effective data support for optimizing the transportation organization scheme.

It should be noted that the drawings are greatly simplified and all use non-precise proportions, only to facilitate and clearly assist in explaining the purpose of the embodiments of the present application. In order to make the purpose, features and advantages of the present application more obvious and easy to understand, please refer to the drawings. It should be noted that the structure, proportion, size, etc. shown in the drawings attached to the present specification are only used to illustrate the content disclosed in the specification, so as to be understood and read by those skilled in the art, and do not limit the conditions for implementing the present application, so they do not have technical significance.

[0031] Train working diagram is a line graph showing the time of train running in each section of railway and the time of train stopping and passing in each station by using coordinate principle. Train working diagram stipulates the procedure of each train occupying section, the time of train arriving and departing (or passing) in each station, the running time of train in section, the stopping time of train in station and locomotive route, etc. Therefore, it is the basis of railway traffic organization. In train working diagram, train is usually regarded as a mass point and the track of train running is represented as a slant line, which represents the running line of train. Train working diagram system is a computer system for preparing, managing, optimizing and simulating train working diagram.

[0032] Section running gap is the time interval between two consecutive trains in the same section. The present application provides a railway section running gap alarm method, as shown in the figure, comprising the following steps: Figure 1 S1, section running gap identification: according to the pre-defined key attention section rule, automatically scan the train working diagram stage plan of train working diagram system, identify and calculate the running gap of key attention section.

[0033] The key attention section includes the section affected by construction and maintenance, operation disclosure, meteorological disasters, and the running section of temporary passenger, super-long, super-limit, military and detection trains. The key attention section supports dynamic configuration and update.

[0034] The train working diagram stage plan includes 3-4 hour stage plan.

[0035] S2, running gap alarm judgment: compare the running gap calculated in step S1 with the standard time of each section running gap based on the transport regulations, judge whether the running gap is over limit, if the running gap exceeds the range of the standard time, generate and trigger alarm, and execute three branch processes in parallel, i.e. steps S3, S4 and S5; if it does not exceed the range of the standard time, return to step S1 and continue monitoring.

[0037] Further, the lower limit of the standard time is the minimum safety interval threshold, and the upper limit of the standard time is the maximum planned interval threshold. Running gap over limit includes two cases of running gap too long and running gap too short. Running gap too long means that the running gap is greater than the maximum planned interval threshold, which will cause time waste and affect efficiency; running gap too short means that the running gap is less than the minimum safety interval threshold, which will endanger safety.

[0038] ​S3, branch one, running gap real-time monitoring: continuously monitor the real-time changes of the running line, and update the running gap state and alarm information in real time according to the changes of the running line. When the running line changes cause the running gap state to change, the running gap state and the corresponding alarm information are dynamically updated; when the running line does not change, the running gap state is continuously monitored.

[0039] Specifically, by subscribing to the change events of the running graph system in real time through the message middleware, the real-time monitoring of the running line changes is realized, and the real-time and accuracy of the running gap state monitoring are ensured.
