1. A safety management method of a temporary speed restriction for a multimode train control system, comprising the following steps:
step 101, issuing, by a dispatcher, a temporary speed restriction setting instruction by means of a hardware processor of a line network dispatching system;
step 102, receiving, by a temporary speed restriction server (TSRS), the temporary speed restriction setting instruction issued by the hardware processor of the line network dispatching system, checking a validity of a set temporary speed restriction, and setting a state of a temporary speed restriction instruction as a first symbol of an establishment after the checking is passed;
step 103, determining, by the TSRS, that the set temporary speed restriction is verified as successful, and setting the state of the temporary speed restriction instruction as a second symbol of a verification;
step 104, providing, by the TSRS, feedback on a verification state of the set temporary speed restriction or the verification failed to the dispatcher;
step 105, issuing, by an assistant dispatcher, an execution instruction for the temporary speed restriction, which is verified;
step 106, determining, by the TSRS, that the temporary speed restriction is executed successfully, and setting the state of the temporary speed restriction instruction as a third symbol of an execution;
step 107, providing, by the TSRS, feedback on an execution state of the temporary speed restriction or the execution failed to the dispatcher; and
step 108, sending, by a hardware processor of a train control system (TCC) and a zone controller (ZC), the temporary speed restriction to a train, which has a corresponding system, passing a speed restriction zone.
