s700: when the first traversal result has an overlapping area with the first block partition matching set, block partition identification is carried out through speed limit information of a second overlapping area to obtain a second identification result;
specifically, when the analyzed message temporary speed limit range is overlapped with the block subarea, the first overlap area is marked with the message temporary speed limit in the first overlap area, and the message speed limit value is marked at the same time. And obtaining the first identification result as the temporary speed limit information of the message. And traversing all the temporary speed limits of the checked lines from the TSRS interface contained in the line data to obtain the first traversal result. And when the line temporary speed limit is overlapped with the block subarea, marking the line temporary speed limit in the block subarea, and marking the line speed limit value to obtain a second marking result. And obtaining the temporary speed limit identifier of the message as the first identifier result and the temporary speed limit identifier of the line as the second identifier result, and laying a foundation for checking the first identifier result and the second identifier result in the block partition.
S800: and checking through the first identification result and the second identification result.
Specifically, the temporary speed limit reverse-solution check of the responder message is carried out according to the first identification result and the second identification result. The result generated by the temporary speed limit information of the active responder message is subjected to inverse solution verification, and whether the generated temporary speed limit information in the active responder message is matched with the temporary speed limit information passing the verification from the TSRS interface or not is compared on the basis of an independent logic algorithm, if the temporary speed limit information is not matched with the temporary speed limit information passing the verification, the verification fails, so that the safety of the system output result is ensured, and the independence of the inspection is ensured on the basis of the independent algorithm logic.

In digital signal transmission, a scrambler is usually added at a transmitting end, and a descrambler is added at a corresponding receiving end. The descrambler reduces the scrambled sequence to the transmitter's digital sequence at the receiving end. Scrambling and descrambling take advantage of the orthogonality of the scrambling codes. The scrambling code generally used is a pseudo-random sequence code, and the decoding function can be realized as long as a generator of the same scrambling code is arranged at the receiving end. Descrambling is carried out on the first storage message, 830 original messages are descrambled from 1024 bit messages pre-output in the period, and a CTCS-2 temporary speed-limiting user information packet is analyzed from the original messages, wherein the CTCS-2 is a train operation control system based on track transmission information, and the temporary speed-limiting information of the messages, including information such as quantity, name, speed, length and the like, is analyzed from the CTCS-2 information packet.

Specifically, when the identification speed of the first identification result is higher than the identification speed of the second identification result, the verification is failed. And the active responder where the message is located carries out message output marking, and the message is not output in the period as the first marking result. At this time, all stations and all station transponders end traversing. And according to the verification result, if the verification fails, stopping the final output of the pre-output message, otherwise, externally outputting according to the pre-output message. And comparing whether the temporary speed limit information in the generated active responder message is matched with the temporary speed limit information passing the verification from the TSRS interface or not, if not, the verification fails, guiding the safety side to stop outputting the responder message, and ensuring the safety of the output result of the system.
Further, the embodiment of the present application further includes:
s131: and when the first type judgment result does not meet the first requirement, ending the verification of the active responder corresponding to the responder message.
