The train automatic operation monitoring unit ATS is used as a human-computer interface of an operator, and the operator can check the states of the RATP recovery processes of the train automatic operation protection units in all areas through the train automatic operation monitoring unit ATS; after the restarting data of the automatic train operation protection unit RATP is recovered, an operator needs to confirm whether to start full-automatic operation or not through the automatic train operation monitoring unit ATS.
Preferably, the area recovery server RRS receives the train automatic operation protection unit RATP data when the train automatic operation protection unit RATP is operating normally, and stores it in the volatile memory. And when the train automatic operation protection unit RATP is restarted, the zone recovery server RRS feeds back the latest stored data to the train automatic operation protection unit RATP.
Preferably, the train automatic operation protection unit RATP transmits "normal" and "start" information to the zone restoration server RRS. When the train automatic operation protection unit RATP operates normally, the train automatic operation protection unit RATP sends a "normal" message to the area recovery server RRS, and the area recovery server RRS sends a null message to the train automatic operation protection unit RATP to indicate confirmation after receiving the "normal" message, and the area recovery server RRS overlays the old data with the new data. When the train automatic operation protection unit RATP is started, the train automatic operation protection unit RATP sends start information to the regional recovery server RRS, and the regional recovery server RRS sends latest data to the train automatic operation protection unit RATP after receiving the start information.
Preferably, when the automatic train operation protection unit RATP normally operates, the automatic train operation protection unit RATP calculates the CRC of the data when transmitting the data to the area recovery server RRS for storage, and forwards the CRC to the automatic train operation monitoring unit ATS for storage through the automatic train operation unit RATO. The CRC includes write and return instructions. When the train automatic operation monitoring unit ATS receives a write command, the new CRC will cover the old CRC; when the train automatic operation monitoring unit ATS receives a return instruction, the train automatic operation monitoring unit ATS does not receive a new CRC any more, and feeds back the stored CRC to the train automatic operation protection unit RATP through the train automatic operation unit RATO. When the train automatic operation protection unit RATP is restarted, the train automatic operation protection unit RATP calculates the CRC of the data after recovering the data from the area recovery server RRS, and the train automatic operation monitoring unit ATS stores the CRC information and also sends it to the train automatic operation protection unit RATP. When the two CRCs are the same, the data is trusted, and when the two CRCs are different, the data is considered invalid. The CRC information is used for ensuring that RRS data of the area recovery server is consistent with data of the train automatic operation protection unit RATP when the train automatic operation protection unit RATP is restarted.
Preferably, the region restoration server RRS stores data mainly including trackside limiting conditions and fully automatic operating conditions. The network is mainly used for data transmission.
As shown in fig. 1, one zone recovery server (zone recovery server RRS) may store the train automatic operation protection unit RATP data of a plurality of zones. When the train automatic operation protection unit RATP is started, the regional recovery server RRS feeds back different regional data to the corresponding regional train automatic operation protection unit RATP.
As shown in fig. 2, S1: when the RATP fault of the automatic train operation protection unit is restarted, all sections in the area apply cold start zero speed, at the moment, the train in the protection mode in the area cannot operate, and the trains in the adjacent areas are forbidden to enter the area;
s2: the train automatic operation protection unit RATP sends 'start' information to the regional recovery server RRS, and when the regional recovery server RRS receives the 'start' information, the stored trackside limit data is sent to the train automatic operation protection unit RATP; s3: the train automatic operation protection unit RATP receives RRS data of an area recovery server and checks whether the limit condition beside a recovery track is met; when the conditions are met, the automatic train operation protection unit RATP restores the trackside limiting conditions; when the condition is not met, the train automatic operation protection unit RATP sends unsatisfied information to the train automatic operation monitoring unit ATS through the train automatic operation unit RATO, and an operator remotely starts the train automatic operation protection unit RATP through the train automatic operation monitoring unit ATS; s4: after the trackside limiting conditions are recovered, the stored full-automatic train operation data are sent to a train automatic operation protection unit RATP; s5: the train automatic operation protection unit RATP receives RRS data of the regional recovery server, and the train automatic operation protection unit RATP needs to check whether the recovery full-automatic operation condition is met; when the conditions are met, the automatic train operation protection unit RATP restores the full-automatic train operation conditions; when the condition is not met, the train automatic operation protection unit RATP sends unsatisfied information to the train automatic operation monitoring unit ATS through the train automatic operation unit RATO, and an operator remotely starts the train automatic operation protection unit RATP through the train automatic operation monitoring unit ATS; s6: when the train automatic operation protection unit RATP restores the train full-automatic operation condition, an operator confirms whether to start full-automatic operation or not; after an operator confirms that the train is started to run fully automatically, the automatic train running protection unit RATP releases the cold start zero speed, and the train runs in a full-automatic mode; s7: when the automatic train operation monitoring unit ATS carries out remote start of the automatic train operation protection unit RATP, an operator needs to manually apply a trackside limiting condition through the automatic train operation monitoring unit ATS, and after the automatic train operation protection unit RATP is restarted or the operator manually applies the trackside limiting condition, the automatic train operation protection unit RATP releases the cold start zero speed, and the train starts to operate in a manual driving mode; s8: and after the manual driving mode train meets the full-automatic operation condition, the operator confirms that the full-automatic operation is started, and the train operates in the full-automatic mode.
