Description
Technical Field

Background
The signal system of the rail transit is a command system with high automation degree, and along with the continuous deep operation of the refinement degree, the functional requirements on the vehicle-mounted computer are more and more abundant, so that the production capacity of the vehicle-mounted control program running on the vehicle-mounted computer is more and more required.
The train control program is a vehicle-mounted control program of a signal system of rail transit and is used for a vehicle-mounted computer. The train control program needs real-time response, and the real-time property of acquisition and processing is ensured. In the production process of the train control program, debugging, testing and other works are required before the train control program is on line in the formal engineering, so that the safety and effectiveness of the train control program are ensured.
Currently, two conventional test modes can perform the testing of train control programs.
One is to install the train control program on a vehicle-mounted computer that is consistent with the field. The method has good verification accuracy, and the time delay of the program operation process is completely consistent with the engineering environment. However, it is this consistency that makes it difficult to acquire the running state of the program in real time. Because of the many intermediate states of program operation, such as intermediate data interacted between CPU and memory during program operation, the on-board computer of the engineering environment will not save all states, and typically only the final data or communication data is monitored. The working frequency of the vehicle-mounted computer cannot be accelerated, real-time processing playback is difficult, if a certain scene needs to be reproduced, the original state needs to be reset, and each function has long debugging and testing time. Meanwhile, the vehicle-mounted computer belongs to a special computer carrying a real-time operating system, so that the customization price is higher, the maintenance amount of debugging and testing is smaller, and the production capacity is further improved.
Another is to migrate the train control program to a general purpose computer-installed non-real time operating system, such as a personal computer (PC, personal Computer), etc. The method has lower debugging and testing cost and plays a certain role in function verification, but the time delay is different from that of an actual vehicle-mounted computer, so that the reason for transplanting or the reason for realizing the function is difficult to determine, and the method brings trouble.
In conclusion, the existing train control program has the defects of high cost, poor economy and the like.

The test method of the train control program based on the general purpose computer can be realized based on the non-real-time operating system multithreading, multiprocessing and various storage sharing modes of the general purpose computer so as to simulate the real-time scheduling capability of the vehicle-mounted computer.
Illustratively, the general-purpose computer CPU has a single core computing performance that is 10 times that of the vehicle-mounted computer CPU.
Illustratively, the number of general purpose computer cores may be 4 or 8 or 16 or more.
Illustratively, as shown in fig. 2, the simulator operates in a multi-process manner, including an interaction process, a management process, a data process, a display process, an acquisition process, and a core process;
the interaction process is responsible for setting various parameters, setting working modes and the like, and can automatically set contents to other processes according to the planned tasks, so that the interaction process is the input of simulator man-machine interaction.
And managing a process high-precision time shaft, and responsible for multi-process scheduling execution, and setting a time system for other processes according to the working frequency set by the interactive process.

The acquisition process generates simulation data according to the working mode appointed by the interaction process, responds to the data frequency of the management process, and transfers the generated data to the data process.
The core process is used for loading the target binary program of the vehicle-mounted computer, processing according to the working frequency set by the management process, receiving the data input by the acquisition process of the data process, and transferring the intermediate data state calculated by the target binary program into the data process, wherein the intermediate data state not only comprises the calculation result, but also can store various intermediate working states, and can accept the interaction process command, thereby realizing the functions of suspending, stopping, loading the intermediate state operation and the like.
Fig. 3 is a workflow diagram of a core process in the method for testing a train control program based on a general-purpose computer provided by the application. The workflow of the core process may be as shown in fig. 3.
The above is a way of interaction between the main functions of the process and the process, wherein the core process is more complicated to process due to the need to load the target binary program.
The core process simulates various driving response programs and is used for simulating original hardware equipment which needs to be checked and interacted when a target binary program of the vehicle-mounted computer runs, and the original hardware equipment comprises a computing device, a speed measuring device, a storage device, a communication device, a clock device and the like.

The core process simulation calculation is to simulate the CPU calculation process of the vehicle-mounted computer, and convert the instruction of the target binary program to the vehicle-mounted computer into the instruction of the general computer system, so as to realize the calculation of the simulated vehicle-mounted computer.
In the process, the core process receives the working frequency set by the management process, so that the instruction conversion time is adjusted, and the response speed of the analog peripheral is adjusted, so that the multi-speed processing is realized.
For example, the process of a single test may include the steps of:
loading a train control program of a certain version by the simulator;
the working scene is stop-in and stop-off, and the first multiple is set to be 5 times;
the version adds the linkage shielding door treatment for the station entering and stopping functions;
the interaction process sets the working scene to be 1km in advance, and sets the first multiple to be 5 times after passing through 3 sections, two annunciators and four transponders;
the management process receives 5 times of the interactive process setting, starts all other processes, sets the working frequency to the other processes, and determines that the processes needing to be started are started;
starting a data process, starting an acquisition process, setting the distance to be moved of a train according to the setting of an interaction process, setting the number and the positions of annunciators and setting the number and the positions of transponders;
the display process is started to display the set parameters, the train position, the corresponding operation parameters and the like
The core process is started, the train control program of the version is loaded, and the core process converts a self-checking instruction of the train control program into an instruction for checking the starting of related simulation equipment;
after the related devices are started, the core process converts the communication instruction of the train control program into a data process interaction instruction, and information such as a map simulation position, a simulation speed value and the like is obtained;
the core process converts the self processing logic of the train control program into a general calculation instruction to carry out relevant cycle check;
the core process converts the output instruction of the train control program into a data process interaction instruction and outputs the internal state to the data process;
it should be noted that, because the first multiple is set to be 5 times, the running speed of the process is 5 times that of the original process;
the simulator is faster than the running speed on an actual vehicle-mounted computer by 5 times, the acquisition speed is also faster by 5 times, the moving speed is provided by the simulation speed measurement, and the acceleration and the deceleration are both improved by 5 times;
logic added by a train control program can be converted into a mode that a group of shielding gate states are acquired for a data process, and other processes are similar;
the core process converts and sends various intermediate states of the train control program to the data process;
assuming that suspension is needed, the core process stops processing, the intermediate state is saved, if the intermediate state needs to be continued, the intermediate state is restored, and the processing after the completion of the content saved by the data process is completed;
if the state of the shielding door is set to be open through the interactive program, after the train control program runs, the shielding door is found to be not normally closed, other processing is caused, the state can be sent to a data process, and an electronic report is formed by the specification of the interactive process, so that the added function of the train control program is determined to be effective;
if the state of the shielding door is set to be open through the interactive program, after the train control program runs, the shielding door is found to be not normally closed and is not subjected to corresponding processing, the state can be sent to a data process, and an electronic report is formed through the specification of the interactive process, so that the abnormal function of the train control program is determined.
