In a CBTC (train control and train control) system for rail transit, interfaces between interlocking equipment and axle counting equipment are divided into a relay mode and a communication mode. When the interlocking equipment interacts with the axle counting equipment in a relay mode, a large amount of manual wiring exists between the interlocking circuit and the relay circuit, and therefore the hidden danger of 'wire connection sealing' still exists. When the interlocking equipment and the axle counting equipment are communicated in a relay interface mode, the axle counting equipment converts the axle counting section state collected by the axle counting magnetic head into an analog signal to control the suction and falling of a relay; when the interlocking is set to reset or pre-reset the axle counting, information interaction is also carried out by driving the reset relay and the pre-reset relay to act.
When the relay circuit breaks down, the fault position still needs to be judged manually and then corresponding processing is carried out. After the circuit short circuit fuse is subjected to wire breakage protection, the fuse also needs to be replaced manually. This all brings certain problems for the operation and maintenance departments; when the interlocking device interacts with the axle counting device in a communication mode, the communication protocols of the axle counting device and the interlocking device produced by different manufacturers are different, and certain difficulty exists in installation and debugging of the interlocking system. Based on the method, the communication method of the computer interlocking system and the axle counting simulation system can support the interlocking device and the axle counting device to communicate in a relay mode, and meanwhile, supports the communication of various axle counting devices and the interlocking device. The axle counting simulation system can easily and quickly debug the data interaction between the interlocking equipment and the axle counting equipment of various manufacturers, and realize the communication between the various axle counting equipment and the interlocking equipment.

In the embodiment of the present invention, the axle counting simulation system receives second data sent by the computer interlocking system based on the second channel, where the second data may specifically be a data packet sent by the computer interlocking system based on the second channel.
It should be noted that the first channel and the second channel are redundant to each other, and when communication of one of the channels between the computer interlocking system and the axle counting simulation system is interrupted, data interaction between the computer interlocking system and the axle counting simulation system is automatically performed through the other channel.
In the embodiment of the present invention, the axle counting simulation system receives first data sent by the computer interlocking system based on the first channel, and simultaneously, the axle counting simulation system receives second data sent by the computer interlocking system based on the second channel, and performs check on the first data and the second data respectively to obtain a check result, that is, a first check result, where the check may specifically be performing timeout check and integrity check on the first data and the second data, and more specifically, performing check on timeout and integrity of the first data and the second data based on CRC check.

Further, in an embodiment, the method may further specifically include:
transmitting third data to the computer interlock system based on the first channel;
and sending fourth data to the computer interlocking system based on the second channel so that the computer interlocking system can verify the third data and the fourth data, and determining second target data according to a second verification result.
Optionally, the axle counting simulation system sends third data to the computer interlocking system based on the first channel, where the third data may be specifically a data packet sent by the axle counting simulation system based on the first channel. Meanwhile, the axle counting simulation system sends fourth data to the computer interlocking system based on the second channel, and the fourth data may specifically be a data packet sent by the axle counting simulation system based on the second channel.
In the embodiment of the present invention, after receiving the third data and the fourth data, the computer interlock system checks the third data and the fourth data to obtain a second check result, which may specifically be timeout check and integrity check on the third data and the fourth data, and more specifically, timeout and integrity check on the third data and the fourth data based on CRC check.
And the computer interlocking system obtains the credit data, namely the second target data according to the second check result.
Further, in an embodiment, the verifying the first data and the second data to obtain a first verification result may specifically include:
and carrying out integrity check and overtime check on the first data and the second data to obtain the first check result, wherein the integrity check is to check the content and the length of the first data and the second data, and the overtime check is to check the first receiving time, the first sending time and the first preset overtime of the first data and the second data.
In the embodiment of the present invention, the first receiving time may specifically be a time when the axle counting simulation system receives the first data and the second data sent by the computer interlocking system, the first sending time may specifically be a time when the computer interlocking system sends the first data and the second data, and the first preset timeout time may be freely set for the axle counting simulation system.
In the embodiment of the present invention, the axle counting simulation system calculates the time required for the axle counting simulation system to receive the first data and the time required for the axle counting simulation system to receive the second data based on the first receiving time and the first sending time of the first data and the second data, specifically, the time required for the axle counting simulation system to receive the first data is obtained by subtracting the first sending time of the first data from the first receiving time of the first data, the time required for the axle counting simulation system to receive the second data is obtained by subtracting the first sending time of the second data from the first receiving time of the second data, and the size relationship between the time required for the axle counting simulation system to receive the first data, the time required for the axle counting simulation system to receive the second data, and the first preset timeout time is determined.
For example, if the time required for receiving the first data is less than a first preset timeout time, the first data is considered to pass the timeout check; if the time required for receiving the first data is longer than the first preset timeout time, the first data is considered not to pass the timeout check, and the first channel communication is considered to be interrupted at the moment. And if the content and the length of the received first data are consistent with the expectation, the first data are considered to pass the integrity check.
For example, if the time required for receiving the second data is less than a first preset timeout time, the second data is considered to pass the timeout check; and if the time required for receiving the second data is longer than the first preset timeout time, the second data is considered not to pass the timeout check, and the computer interlocking system considers that the communication of the first channel is interrupted. And if the content and the length of the received second data are consistent with the expectation, the second data are considered to pass the integrity check.
It should be noted that, when the axle counting simulation system judges that communication with the computer interlocking system is interrupted or data fails to pass verification, the axle counting simulation system sets the state of the interlocking equipment in the computer interlocking system to be An Quantai so as to ensure safe operation of the train. For example, when the computer interlock system receives that the third data and the fourth data of the axle counting simulation system do not pass the verification, the data packets corresponding to the third data and the fourth data are discarded, and it is considered that no valid data is received in the current period. Similarly, when the axle counting simulation system receives that the first data and the second data of the computer interlocking system do not pass the verification, discarding the data packets corresponding to the first data and the second data, and considering that the valid data of the computer interlocking system is not received in the current period. If the receiver receives a piece of data from a certain channel, which passes the receiving time timeout and the integrity check, the communication of the channel can be considered to be uninterrupted. When the computer interlocking system and the axle counting simulation system receive data, if and only if the time required for receiving the data is within a preset timeout time range, receiving application program data in a data packet corresponding to the received data; if the time required to receive the data exceeds a preset timeout time, the data is discarded.

and if the first verification result represents that the first data and the second data both pass the integrity verification and the overtime verification, determining the first target data according to the data serial numbers of the first data and the second data.
Optionally, if the first verification result indicates that the first data passes the integrity check and the timeout check, the first data is used as final first target data; if the first check result shows that the second data passes the integrity check and the overtime check, the second data is used as final second target data; and if the first verification result represents that the first data and the second data both pass the integrity verification and the overtime verification, selecting the data with the newer data serial number as the first target data from the data serial numbers of the first data and the second data.
In other embodiments of the present invention, if the data serial numbers of the first data and the second data are consistent, the previous data is used as the first target data according to the time when the axle counting simulation system receives the first data and the second data.
