1. and the vehicle-mounted controller OBCU carries out three times of sleep requests and confirmation in the sleep process and vehicle fault monitoring, namely the sleep request, the sleep command and the confirmation of sleep preparation. Compared with a single request in the prior art, the multiple interactive confirmation ensures that the vehicle fully executes the dormancy preparation operation and the safety protection after the train dormancy power-off. And automatically executing signal self-checking, vehicle self-checking and signal vehicle combined testing in the awakening process. The signal self-checking ensures that all signal equipment is tested normally, the vehicle self-checking ensures that all train control subsystems of the vehicle are tested normally, the signal vehicle combined test comprises braking self-checking, linkage test and departure test, and the vehicle-mounted controller OBCU and a vehicle interface are ensured to meet the full-automatic unmanned driving function. Compared with the prior art, the automatic awakening process reduces the workload of manual self-checking, improves the working efficiency of the system and ensures the real-time safety protection of the whole process. If the signal self-check fails, the OBCU forcibly outputs emergency braking according to the fail-safe principle without releasing, and the departure condition is not met; in the self-checking process of the vehicle, the OBCU forcibly outputs emergency braking without releasing to ensure that the vehicle does not move; and in the vehicle linkage test, the OBCU monitors the accumulated moving distance of the vehicle in real time, and if the accumulated moving distance exceeds the limit, the OBCU forcibly outputs emergency braking according to a failure safety principle, does not relieve the brake and gives an alarm to wake up failure. The departure test in the combined test automatically executes the wakening beacon to check the train position and the dynamic test without manual confirmation. Compared with the independent dynamic test in the prior art, the method integrates the conventional dynamic step test and the position check, greatly improves the automatic efficiency of function execution and the dispatching efficiency in the garage, avoids the irreversible physical abrasion of the brake shoe and the locomotive wheel in the step test, and prolongs the service life of the brake shoe and the locomotive wheel.
2. The trackside zone controller ZC automatically checks the position of a current object train in the whole sleeping and awakening process, supervises and safely protects the sleeping and awakening zone where the operation object is located, does not need manual confirmation any more, and is safe and efficient.
The central monitoring system ATS supports automatic triggering of a dormancy awakening task, and monitors the state of the current object train in real time in the whole dormancy and awakening process, if abnormity and dormancy awakening failure occur, detailed alarming is given and dispatching personnel are prompted, and the safety of the process is guaranteed.
