Description
Technical Field

Background
A Communication-Based Train Control System (CBTC) is a System that performs real-time bidirectional wireless Communication between a Train and ground equipment to monitor and Control the safe operation of the Train. The System consists of subsystems and equipment such as an interlock, an ATS (Automatic Train Protection), an ATP (Automatic Train Operation), an ATO (Automatic Train Operation), a Device Communication System (DCS), a Maintenance Support System (MSS) and the like. The interlock and the ATS are mainly used for ensuring train safety and condition monitoring, so that the requirement on the correctness of communication between the interlock and the ATS is high, and point-to-point testing is required. The point-to-point test is used for testing the correctness of the corresponding relation between the equipment name and the state of the code bit between the interlock and the ATS and the name and the state of the actual equipment.
The point-to-point test between the existing interlock and the ATS is as follows: firstly, a tester determines the corresponding relation between the states of signal machines, tracks, turnouts and other devices in communication data of the interlocks and the ATS and binary bits of a communication data packet by reading a code bit table. And secondly, manually operating the ATS control equipment and changing the state of the ATS control equipment, manually capturing packets through a plug-in or a network built in the ATS, and manually screening communication data between the interlock and the ATS from a large number of data packets of network communication. And thirdly, finding the equipment name and the state of the corresponding code bit of the communication data by the tester according to the corresponding relation of the equipment name, the equipment state and the bit. And finally, the tester confirms whether the equipment name and the state of the code bit are correctly changed or not and manually records the result.
The point-to-point test between the existing interlock and the ATS is carried out through manual operation, and the test efficiency is low due to long time consumption of the manual operation. And the name and the state of the equipment at the code bit of the communication data packet captured when the state of the equipment is changed need to be compared with the name and the state of the actual equipment with the changed state manually, the data volume of the comparative work is large, the test is easy to make mistakes due to visual fatigue, and the test accuracy cannot be ensured.

For example, the correspondence may be expressed as: 631 — X0406-R, where 631 is the bit ordering, X0406 is the signal name, and R is the red light.
A set of CBTC system comprises a plurality of stations, the sizes of different stations are different, so the number of devices of different stations is different, and the length of communication data between the interlocking and ATS of different stations is different.

For example, the communication packet between the interlock and the ATS of the destination station captured by step S203 has 100 bits, and the communication protocol may define that the first 20 bits of the communication packet are IP-related information, 21 to 59 are station names of the station, and 60 to 100 bits are device names and device states according to the 100 bits of information of the communication packet.
Specifically, whether the equipment state of the target station changes or not is detected, if yes, data packets irrelevant to equipment change, such as heartbeat data packets, time synchronization data packets, connection maintaining packets and the like, are filtered out from communication data packets according to a communication protocol between the interlock and the ATS, and only data packets related to equipment information between the interlock and the ATS are reserved.

For example, the correspondence relationship may be expressed as: 631 — X0406-R, where 631 is the bit ordering, X0406 is the signal name, and R is the red light. To determine the device name and the device status of the target bit "1" of the captured communication data packet, it may be determined that the target bit "1" is the bit of the 631 th bit, and the device name of the semaphore X0406 and the device status of the red light may be obtained by locating the 631 th bit of the captured communication data packet to the corresponding 631 in the correspondence.

Once the daemon is started as a service, the daemon will automatically start as soon as the ATS computer is started, without the need for the operator to repeat this step. By starting the remote data packet forwarding daemon on the computer where the ATS is located, other computers in the LAN can acquire the network communication data packet between the ATS and the interlock.
Usually, a set of CBTC system comprises a plurality of stations, each station is provided with an interlock and an ATS system, and the communication packet capturing of all station interlocks and ATSs on one computer can be realized by starting a remote data packet forwarding daemon in a test environment through all ATS computers, so that the condition that a plurality of sets of ATS equipment are switched due to the need of testing is avoided.
And step two, reading the required interlocking and ATS data according to the configuration file.
Specifically, the point-to-point test program reads the interlock and ATS data used in the test environment according to the configuration file. The program can only read the interlocking and ATS data of the target station to be tested, and can also read the interlocking and ATS data of all stations of the urban rail line at one time.
And thirdly, analyzing the read interlocking and ATS data to obtain the corresponding relation among the equipment name of each equipment in the relevant station, the various equipment states of each equipment and the bit sequence in the data packet from the ATS to the interlocking, and the corresponding relation among the equipment name of each equipment in the relevant station, the various equipment states of each equipment and the bit sequence in the data packet from the interlocking to the ATS data.
The station types of different stations are different, so the number of devices in the stations is different, and the communication data lengths of ATSs and interlocks of different stations are different. The point-to-point test program obtains the number of the devices of the station, the length of the communication data, the bit position in the communication data corresponding to the state of each device and the corresponding value by analyzing the read interlocking and ATS data of each station, and establishes the corresponding relation between the device state and the bit position of each station for subsequent data analysis and result judgment.
And step four, connecting the ATS of the target station to be tested and maintaining the connection.
The point-to-point test program establishes connection with the ATS computer of the target station to be tested and maintains the connection, thereby avoiding the connection from being suspended or interrupted due to no activity within a period of time.
And fifthly, capturing the communication data packet between the interlock of the target station and the ATS through a remote data packet forwarding daemon process.
Wherein the communication data packet includes the target bit. The communication packets include packets from the ATS to the interlock and packets from the interlock to the ATS.
Specifically, the data packets from the ATS to the interlock and the data packets from the interlock to the ATS of the target station are captured through a remote data packet forwarding daemon connected with the target station.
And step six, detecting whether the equipment state of the target station is changed, if so, executing step seven, and if not, executing step five.
Specifically, the point-to-point test program detects whether the equipment state of the target station changes, if so, the seventh step is executed, and if not, the fifth step is executed, namely, the communication data packet between the interlock of the target station and the ATS is captured through the remote data packet forwarding daemon process.
For example, whether the state of the equipment at the target station changes may be detected by turning on or off the green light of the traffic signal, and the detection of the state change of the equipment at the target station is not limited herein.
And seventhly, filtering the captured communication data packet between the interlock and the ATS according to a communication protocol between the interlock and the ATS to obtain a communication data packet of the equipment information between the interlock and the ATS.
Specifically, according to the acquired communication protocol between the interlock and the ATS, data packets irrelevant to device changes, such as heartbeat data packets, time synchronization data packets, connection maintaining packets and the like, are filtered from the captured communication data packets between the interlock and the ATS, and only data packets related to device information between the interlock and the ATS are reserved. Wherein the communication data packet of the interlocking and inter-ATS device information includes a data packet of the device information from the ATS to the interlock and a data packet of the device information from the interlock to the ATS.
Data packets irrelevant to equipment change in communication data packets are filtered through a communication protocol, the data volume to be processed can be reduced, and the test performance is improved.
Eighthly, determining control code bits from the ATS to the data packet of the interlocked equipment information according to the corresponding relation among the equipment name of each equipment in the relevant station, the equipment state of each equipment and the bit sequence from the ATS to the data packet of the interlocked equipment information obtained in the third step; and determining the code bits from the data packet of the device information interlocked to the ATS according to the corresponding relation among the device name of each device in the related station, the state of each device and the bit sequencing in the data packet from the interlock to the ATS data.
The code bits are the device name and the device state, and the control code bits and the representation code bits both contain the device name and the device state.
And step nine, respectively judging whether the equipment name and the equipment state of the control code bit and the equipment name and the equipment state of the representation code bit are consistent with the obtained actual equipment name and the obtained actual equipment state of the target station with the changed actual equipment state.
Specifically, when the device state of a certain station changes, the control code bit and the expression code bit are determined from the captured communication data packet, and compared with the device and the bit list which are analyzed before, the change of the communication data is converted into the code bit change of the corresponding device. And then comparing the name and the state of the equipment represented by the code bit according to the actual condition of the equipment state of the station, and judging whether the name and the state of the equipment actually changed by the station are consistent or not, thereby judging whether the code bit correctly corresponds to the equipment state or not.
If the names of the control code bit and the representation code bit are consistent with the actual equipment name, and the equipment states of the control code bit and the representation code bit are consistent with the actual equipment state, the control code bit and the representation code bit are considered to pass the test; if the device name of the control code bit or the expression code bit is inconsistent with the actual device name, or the device name of the control code bit and the expression code bit is consistent with the actual device name, but the device state of the control code bit and the expression code bit is inconsistent with the actual device state, the control code bit or the expression code bit is not tested to pass.
As an optional mode of the embodiment of the present invention, the program may record, in the log file, information such as communication data of the target interlock and the ATS captured through the network in the process, a change of a code bit obtained by analyzing the communication data, a name and a state of station equipment corresponding to the changed code bit, and a name and a state of actual equipment corresponding to the station. If the test is not problematic, the log can enhance the reliability of the test; if the test finds the problem, the log can be used for the test and the developer to analyze the problem and locate the error code bit.
Step eleven, writing the control code bit obtained in the step ten and a test result indicating whether the code bit test passes into a result record table.
As an optional mode of the embodiment of the invention, the point-to-point test program can analyze the code bit change through the communication data of the interlock and the ATS, and after comparing the code bit change with the actual equipment state, the result of whether the code bit changes correctly is filled in the code bit test table, so that the automatic unified record of the test result is realized, and the test personnel can check and check conveniently.
Step twelve, detecting whether all code bits are tested and finished by the program.
And if the code bit to be tested still has no corresponding test result, the program jumps to the third step, the communication data packet is grabbed, and the code bit which is not tested yet is waited for testing. And if all code bits to be tested have the test result recorded in the eleventh step, the point-to-point test program ends the default test.
As an optional manner of the embodiment of the present invention, in different application scenarios, the embodiment may cooperate with an application scenario change or add other steps, such as automatically generating a test form including all control code bits and indication code bits after reading ATS and interlock data, generating a test report by changing a format of the test form to be completely filled, and the like.
In the embodiment of the application, the ATS and the interlock are in the same network environment, and the communication data packets of each ATS and the interlock are acquired through a remote data packet forwarding daemon. And simultaneously, reading the data of each ATS and the interlock by the program to obtain the communication data analysis format of each station ATS and the interlock, wherein the format is the corresponding relation between the communication data bit and the actual equipment. The program applies the format to the read communication data packet, analyzes the code bit change of the ATS and the interlocking, compares the actual name and the state of the equipment, obtains a test result and records the test result in an external file. According to the embodiment of the application, the point-to-point test program is used for executing packet grabbing, target communication data packet screening, code bit positioning and result judgment, so that manual operation is omitted, point-to-point test can be performed in a short time and efficiently, the efficiency and the time are improved, and the test risk caused by misjudgment of results due to fatigue and other reasons during manual test can be avoided.
