Description

Technical Field

[0001] The present invention relates to the technical field of train control, and in particular to a simulation TCMS system based on a MaView platform and a vehicle-mounted equipment testing method. Background Art

[0002] The vehicle on-board controller (VOBC) system is composed of the Automatic Train Protect (ATP) and the Automatic Train Operating (ATO). It is the brain system of the vehicle, a high-security system that ensures the safe operation of the train, and the core equipment of the Communication Based Train Control (CBTC) system. It carries the safe operation of the vehicle, and the interface with the Train Control and Management System (TCMS) is quite complex, with a very large amount of data and many interfaces. Therefore, indoor testing of the vehicle-mounted VOBC and TCMS is a great challenge. The current indoor test uses the interaction between the vehicle-mounted VOBC and the simulated TCMS for testing. The current simulated TCMS is a program developed in C++ language. Modifying an interface file requires modifying the code. Both package assembly and unpacking require modification, which is also prone to errors, bringing great inconvenience to development and testing.

[0003] The current development method of simulation TCMS has the following defects:

[0004] 1) Developers have high technical requirements and need to understand VC++ and VS software technology. Simulation maintenance personnel also have high technical requirements.

[0005] 2) The interface data volume is large. Once there is a change in the interface, it is necessary to modify the reading of the interface and the packaging of the interface in the code, and insert the byte into the designed human-machine interface. The code modification volume is large and complicated.

[0006] 3) During interface debugging, the workload is heavy and some intermediate variables are difficult to view.

[0007] 4) During the test, an intermediate logic value error occurred, and it was complicated to find the cause, which increased the workload for the test.

[0049] This embodiment provides a mobile terminal. The mobile terminal can be in the form of a simulated TCMS system based on the MaView platform of the embodiment of the present application. Figure 1 is a structural block diagram of a mobile terminal according to an embodiment of the present application. Figure 1 As shown, the mobile terminal includes: a radio frequency (RF) circuit 110, a memory 120, an input unit 130, a display unit 140, a sensor 150, an audio circuit 160, a wireless fidelity (WiFi) module 170, a processor 180, and a power supply 190. Those skilled in the art will understand that Figure 1 The structure of the mobile terminal shown in the figure does not constitute a limitation on the mobile terminal, and may include more or less components than shown in the figure, or combine certain components, or arrange the components differently.

[0050] Combine the following Figure 1 The following is a detailed introduction to the various components of the mobile terminal:

[0051] The RF circuit 110 can be used for receiving and sending signals during the process of sending and receiving information or making calls. In particular, after receiving the downlink information of the base station, it is sent to the processor 180 for processing; in addition, the designed uplink data is sent to the base station. Usually, the RF circuit includes but is not limited to an antenna, at least one amplifier, a transceiver, a coupler, a low noise amplifier (Low Noise Amplifier, referred to as LNA), a duplexer, etc. In addition, the RF circuit 110 can also communicate with the network and other devices through wireless communication. The above-mentioned wireless communication can use any communication standard or protocol, including but not limited to the Global System of Mobile communication (GSM), General Packet Radio Service (GPRS), Code Division Multiple Access (CDMA), Wideband Code Division Multiple Access (WCDMA), Long Term Evolution (LTE), email, Short Messaging Service (SMS), etc.

[0052] The memory 120 can be used to store software programs and modules. The processor 180 executes various functional applications and data processing of the mobile terminal by running the software programs and modules stored in the memory 120. The memory 120 may mainly include a program storage area and a data storage area, wherein the program storage area may store an operating system, an application required for at least one function (such as a sound playback function, an image playback function, etc.), etc.; the data storage area may store data created according to the use of the mobile terminal (such as audio data, a phone book, etc.), etc. In addition, the memory 120 may include a high-speed random access memory, and may also include a non-volatile memory, such as at least one disk storage device, a flash memory device, or other volatile solid-state storage devices.

[0053] The input unit 130 can be used to receive input digital or character information, and to generate key signal input related to the user settings and function control of the mobile terminal. Specifically, the input unit 130 may include a touch panel 131 and other input devices 132. The touch panel 131, also known as a touch screen, can collect the user's touch operation on or near it (such as the user's operation on the touch panel 131 or near the touch panel 131 using any suitable object or accessory such as a finger, stylus, etc.), and drive the corresponding connection device according to a pre-set program. Optionally, the touch panel 131 may include two parts: a touch detection device and a touch controller. Among them, the touch detection device detects the user's touch orientation, detects the signal brought by the touch operation, and transmits the signal to the touch controller; the touch controller receives the touch information from the touch detection device, converts it into contact coordinates, and then sends it to the processor 180, and can receive and execute commands sent by the processor 180. In addition, the touch panel 131 can be implemented in various types such as resistive, capacitive, infrared, and surface acoustic waves. In addition to the touch panel 131, the input unit 130 may also include other input devices 132. Specifically, other input devices 132 may include but are not limited to one or more of a physical keyboard, function keys (such as volume control keys, switch keys, etc.), a trackball, a mouse, a joystick, etc.

[0054] The display unit 140 can be used to display information input by the user or information provided to the user and various menus of the mobile terminal. The display unit 140 may include a display panel 141. Optionally, the display panel 141 may be configured in the form of a liquid crystal display (LCD), an organic light-emitting diode (OLED), etc. Further, the touch panel 131 may cover the display panel 141. When the touch panel 131 detects a touch operation on or near it, it is transmitted to the processor 180 to determine the type of touch event. Subsequently, the processor 180 provides a corresponding visual output on the display panel 141 according to the type of touch event. Although in Figure 1 In the embodiment, the touch panel 131 and the display panel 141 are used as two independent components to implement the input and output functions of the mobile terminal, but in some embodiments, the touch panel 131 and the display panel 141 can be integrated to implement the input and output functions of the mobile terminal.

[0055] The mobile terminal may also include at least one sensor 150, such as a light sensor, a motion sensor, and other sensors. Specifically, the light sensor may include an ambient light sensor and a proximity sensor, wherein the ambient light sensor may adjust the brightness of the display panel 141 according to the brightness of the ambient light, and the proximity sensor may turn off the display panel 141 and / or the backlight when the mobile terminal is moved to the ear. As a type of motion sensor, the accelerometer sensor can detect the magnitude of acceleration in all directions (generally three axes), and can detect the magnitude and direction of gravity when stationary. It can be used for applications that identify the posture of the mobile terminal (such as horizontal and vertical screen switching, related games, magnetometer posture calibration), vibration recognition related functions (such as pedometer, tapping), etc.; as for other sensors that can be configured in the mobile terminal, such as gyroscopes, barometers, hygrometers, thermometers, infrared sensors, etc., they will not be repeated here.

[0056] The speaker 161 and microphone 162 in the audio circuit 160 can provide an audio interface between the user and the mobile terminal. The audio circuit 160 can transmit the received audio data to the speaker 161 after converting the received audio data into an electrical signal, which is converted into a sound signal for output; on the other hand, the microphone 162 converts the collected sound signal into an electrical signal, which is received by the audio circuit 160 and converted into audio data, and then the audio data is output to the processor 180 for processing, and then sent to another mobile terminal through the RF circuit 110, or the audio data is output to the memory 120 for further processing.

[0057] WiFi is a short-range wireless transmission technology. Mobile terminals can help users send and receive emails, browse web pages, and access streaming media through WiFi module 170. It provides users with wireless broadband Internet access. Figure 1 A WiFi module 170 is shown, but it is understandable that it is not an essential component of the mobile terminal and can be omitted as needed without changing the essence of the invention, or replaced with other short-range wireless transmission modules, such as a Zigbee module or a WAPI module.

[0058] The processor 180 is the control center of the mobile terminal. The processor 180 can be an execution module in the simulated TCMS system based on the MaView platform in the embodiment of the present application. The processor 180 uses various interfaces and lines to connect the various parts of the entire mobile terminal, and executes various functions of the mobile terminal and processes data by running or executing software programs and / or modules stored in the memory 120, and calling the data stored in the memory 120, so as to monitor the mobile terminal as a whole. Optionally, the processor 180 may include one or more processing units; preferably, the processor 180 may integrate an application processor and a modem processor, wherein the application processor mainly processes the operating system, user interface, and application programs, etc., and the modem processor mainly processes wireless communications. It can be understood that the above-mentioned modem processor may not be integrated into the processor 180.

[0059] The mobile terminal also includes a power supply 190 (such as a battery) for supplying power to various components. Preferably, the power supply can be logically connected to the processor 180 through a power management system, so that the power management system can manage charging, discharging, power consumption and other functions.

[0060] Although not shown, the mobile terminal may also include a camera, a Bluetooth module, etc., which will not be described in detail here.

[0061] In this embodiment, the processor 180 is configured to:

[0062] Loading an interface data table file, wherein the table file includes at least one variable;

[0063] Initialize the communication protocol with the on-board controller system;

[0064] Detect whether the variables in the table file are assigned values;

[0065] If it is detected that the variables in the table file are assigned values, the assigned variable values ​​are obtained for logical calculation, and the calculation results are assigned to the corresponding variables in the table file, wherein the vehicle controller system reads the values ​​of the variables in the table file according to the communication protocol.

[0066] In some embodiments, the processor 180 is further configured to:

[0067] If it is detected that the input variable received from the traction system in the table file is assigned a value, then the assigned traction system input variable value is obtained for logical calculation, and the calculation result is assigned to the corresponding variable in the table file; and / or

[0068] Perform logical calculations on the data sent to the traction system, and assign the calculation results to the output variables sent to the traction system in the table file.

[0069] In some embodiments, the processor 180 is further configured to:

[0070] If it is detected that the input variable received from the brake system in the table file is assigned, obtaining the assigned brake system input variable value for logical calculation, and assigning the calculation result to the corresponding variable in the table file; and / or

[0071] Perform logical calculations on the data sent to the brake system, and assign the calculation results to the output variables sent to the brake system in the table file.

[0072] In some embodiments, the processor 180 is further configured to:

[0073] If it is detected that the input variable received from the vehicle controller system in the table file is assigned a value, then the assigned value of the vehicle controller system input variable is obtained for logical calculation, and the calculation result is assigned to the corresponding variable in the table file; and / or

[0074] Perform logical calculations on the data sent to the vehicle-mounted controller system, and assign the calculation results to the output variables sent to the vehicle-mounted controller system in the table file.

[0075] This embodiment provides a simulated TCMS system based on the MaView platform. Figure 2 is a schematic diagram of the structure of a simulated TCMS system based on the MaView platform according to an embodiment of the present application, such as Figure 2 As shown, the system includes:

[0076] The interface module 21 is used to configure the interface data table file and assign the received data to the variables in the table file;

[0077] An execution module 22, used for obtaining the assigned variable values ​​for logic calculation, and sending the calculation results to the vehicle controller system through the interface module 21;

[0078] The protocol configuration module 23 is used to configure the communication protocol with the vehicle-mounted controller system.

[0079] In some embodiments, the execution module 22 includes:

[0080] A traction logic module 221, for performing logic calculations on data received from the traction system and / or performing logic calculations on data sent to the traction system, and assigning calculation results to variables in the table file;

[0081] A brake logic module 222, for performing logic calculations on data received from the brake system and / or performing logic calculations on data sent to the brake system, and assigning calculation results to variables in the table file;

[0082] The vehicle signal logic module 223 is used to perform logic calculations on the data received from the vehicle controller system and / or perform logic calculations on the data sent to the vehicle controller system, and assign the calculation results to the variables in the table file.

[0083] In some embodiments, the traction logic module 221 , the braking logic module 222 , and the vehicle signal logic module 223 synchronize the calculation results of the logic calculations with each other.

[0084] In some of the embodiments, the protocol configuration module 23 configures the communication protocol with the vehicle controller system to be the TRDP protocol.

[0085] The embodiment of the present application develops a simulated TCMS system suitable for testing vehicle-mounted equipment using PLC language based on the MaView platform. The simulated TCMS system is a simulation software that replaces the real vehicle TCMS system to perform indoor support testing of the vehicle-mounted VOBC. Its main function is to perform logical operations by receiving data from the traction system and the braking system, and to perform integrated logical operations with the data sent by the train, and to send the operation results and some vehicle information such as the working status of the traction system and the braking system to the vehicle-mounted VOBC, thereby ensuring the normal operation of the vehicle-mounted VOBC.

[0086] The simulated TCMS system based on the MaView platform communicates with the real vehicle-mounted VOBC system without changing the communication protocol and interface. It is completely consistent with the communication protocol and interface between the real vehicle-mounted VOBC system and the vehicle TCMS system. The TRDP network communication protocol is used for data interaction, which improves the stability of data transmission.

[0087] The specific module functions of the simulated TCMS system based on the MaView platform in the embodiment of the present application are described as follows:

[0088] Interface module: Create an interface module in the program, select the TRDP communication protocol, manually enter the IP address and port number of the program, store the interface data table file in the interface directory of the program design, and select the menu import through the MaView platform visualization interface to directly import it into the In and Out interface modules. The table format is designed as four columns according to the MaView system requirements: data offset, data variable definition column, default value column, and remarks column. After importing once, the table file under the interface path will be automatically loaded after the subsequent program is started. Unlike traditional C / C++ programs that define package and unpack functions, the MaView platform receives data through the port and automatically assigns values ​​to the variables in the table. The MaView platform directly assigns values ​​to the data variables in the interface by receiving data sent from the outside through the bottom layer in real time.

[0089] During indoor testing, the simulated TCMS system has three communication objects, namely: the vehicle controller system, the traction system and the braking system. Therefore, a communication interface file needs to be established in each execution module involved.

[0090] Execution module: It is divided into three modules: traction logic module, braking logic module and vehicle signal logic module.

[0091] Traction logic module: It performs some logical calculations on the data information received from the traction system according to functional requirements, assigns the calculation results to global variables, and performs logical calculations on the data sent to the traction system.

[0092] For example, TCMS needs to send some signal variables to the traction system in real time, such as the collected running direction. The traction system needs to judge this direction, and if there is a fault, it needs to report the fault to TCMS. In each operating mode, TCMS will forward the traction force of ATO to the traction system. TCMS will receive energy-related information such as traction energy consumption and auxiliary energy consumption sent by the traction system for cumulative calculation, and send the total energy consumption to the human-machine interface of the train.

[0093] Braking logic module: It performs some logical calculations on the data information received from the braking system according to functional requirements, assigns the calculation results to global variables, and performs logical calculations on the data sent to the braking system.

[0094] For example, TCMS receives PWM signal fault diagnosis from each brake system and sends the abnormal PWM command to the vehicle signal. Each brake system sends the vehicle's brake application status to TCMS, and TCMS feeds back the brake application status to the vehicle signal system. TCMS sends the brake level and brake status identification bit to the brake system, and after performing logical operations on the conditions of the application instruction sent by the signal module, it can send a brake release instruction to the brake system.

[0095] On-board signal logic module: performs logical operations on the data sent by the on-board VOBC through the results calculated by the traction logic module and the braking logic module, and finally assigns the calculation results to the variables defined in the on-board VOBC interface file.

[0096] For example, TCMS forwards the electric braking force obtained by each traction system to the brake system of each car. The self-test results of the air compressor and other equipment sent by the brake system, the self-test results of the traction system, and the status information of the traction system are forwarded by TCMS to the on-board signal logic module. When dormant, the module receives the results of the traction system and the brake system and forwards them to the on-board signal, etc.

[0097] During indoor vehicle testing, the simulated TCMS system needs to implement the vehicle signal module, traction system related modules, and braking system related functional modules. Other related systems are relatively less involved, such as air conditioning and lighting systems. Variables and default values ​​are directly defined in the program to participate in the calculation. If faults need to be injected, the variable values ​​can be manually modified directly. The simulated TCMS system needs to receive information from the simulated traction system, braking system, and vehicle-mounted VOBC system in real time, and forward information such as the real-time working status of traction and braking systems to the vehicle. Some of this information requires the simulated TCMS system to perform logical operations on the information sent by each system according to demand, so as to send the calculation results to the vehicle-mounted VOBC, and the simulated TCMS system will also receive commands from the vehicle-mounted VOBC and execute them, and feed back the execution results to the vehicle-mounted VOBC.

[0098] The embodiment of the present application receives data through the TRDP protocol, and then performs logical operations through modularization. Each business module runs independently, which improves the high cohesion and low coupling of the program.

[0099] The simulated TCMS system software of the embodiment of the present application is modularized and assigns values ​​to interface output variables. Each module is independent. If a module is not involved in the test, resources can be saved for the platform and the module can be suspended.

[0100] Figure 3 is a schematic diagram of the software module processing flow according to an embodiment of the present application, such as Figure 3 As shown, during the program processing, the periodic received data and the periodic packaged transmission do not need to be manually unpacked and packaged in the program, and the MaView system automatically sends them according to the interface table.

[0101] The simulated TCMS system based on the MaView platform in the embodiment of the present application can achieve the following technical effects:

[0102] 1) Reduce the workload of simulation TCMS development, reduce development technology capabilities, and save labor costs;

[0103] 2) If the interface changes, you only need to re-import the interface data, avoiding errors caused by modifying the code due to interface changes;

[0104] 3) During the test process, testers can clearly view the data values ​​in each interface and see the intermediate values ​​of logical operations, and promptly discover data logic errors, but the hidden error risks caused by correct results;

[0105] 4) Visual operation and visualization of program logic operations improve test efficiency and reduce test risks.

[0106] This embodiment provides a vehicle-mounted equipment testing method for simulating a TCMS system based on the MaView platform.
