Description

Temporary speed limiting issuing method, device, equipment and storage medium for train Technical Field The application relates to the technical field of rail transit, in particular to a temporary speed limit issuing method, device and equipment for a train and a storage medium. Background In the upgrading and reconstruction of a freight railway mobile blocking system, jurisdictions of a newly added Radio Blocking Center (RBC) and a temporary speed limiting server (TSRS) are required to be divided. In order to calculate a true and reliable driving license for a train, the RBC needs to interact information with a computer interlocking system (CI) in the jurisdiction in real time, one RBC can jurisdiction a plurality of CIs, and a single CI is only governed by one RBC. The TSRS can receive the temporary speed limit command issued by the CTC and forward corresponding speed limit information to the RBC to be issued by the RBC to the train, and the single TSRS only fixedly receives the speed limit command issued by one CTC, and the jurisdiction boundary of the TSRS is consistent with that of the CTC. Under the existing train operation control system, the communication relation between the TSRS and the RBC is 'one-to-many', namely, a single RBC only obtains speed limit information from one TSRS. However, considering that the operation types of all CI stations of the existing freight railway line are different, the line condition is more complex than that of the common passenger line, because the RBC has limited capability of calculating the driving license for a plurality of trains at the same time, when encountering a large freight operation station, the RBC has limited range of CI stations which can be administered, and when the administration range of the RBC is overlapped with two CTC administration ranges at the same time, the temporary speed limit information cannot be issued normally.
