Description

Technical Field

[0001] The present application relates to the field of data processing technology, and in particular to an application variable data calibration method and related devices. Background Art

[0002] XCP (Universal Measurement and Calibration Protocol) is a standard protocol for calibrating and measuring parameters in vehicle electronic control units (ECUs). It is widely used in the development and testing of vehicle ECUs. Current ECU chips have evolved from traditional microcontroller units (MCUs) to more powerful system-on-chips (SoCs). Designed for MCUs, the Universal Measurement and Calibration Protocol (XCP) calibrates variable addresses at fixed memory addresses. However, application software on SoCs uses dynamically changeable virtual addresses. To calibrate application software on SoCs, variable addresses are represented by the application's base address plus an offset. The memory addresses of the variables in the original A2L file are replaced with the application's offset address. This design requires each application to have a dedicated A2L file to isolate and manage data.

[0003] Although the current XCP calibration implementation method for application software in SoC (System on Chip) has been adjusted for the dynamically variable addresses of SoC chips, it may still have the following defects: each application software requires a specific A2L file, which makes the management and maintenance of A2L files complicated.

[0048] This application can be applied in the field of data processing. Taking the automotive scenario as an example, the following will introduce multiple application scenarios that have been implemented in products.

[0049] First, the application scenario of this application is introduced.

[0050] This application can be applied to, but is not limited to, applications with data processing capabilities or cloud services provided by cloud-side servers. The following describes each of these:

[0051] In order to solve the above problems raised in the background technology, the embodiment of the present application provides an application variable data calibration method. The application variable data calibration method of the embodiment of the present application is described in detail below with reference to the accompanying drawings.

[0052] Reference Figure 1 , Figure 1 The process diagram of a method for calibrating variable data provided in an embodiment of the present application is as follows: Figure 1 As shown, a data processing method provided in an embodiment of the present application may include steps S401 to S403, and these steps are described in detail below.

[0053] Step S101: Acquire a calibration instruction sent by a calibration tool.

[0054] In the technical solution disclosed in the embodiment of the present application, the application variable data calibration method can be configured in a gateway, which can be an XCP gateway. The gateway is integrated into the target object of the required service. The target object has multiple target applications for variable monitoring. The target object can be an ECU, MCU, VCU or other device. The calibration measurement of the variable data corresponding to each target application in the target object is realized through the gateway.

[0055] For details, see Figure 2 The XCP gateway configuration tool can be used to configure the variable description information of each target application and store the variable description information in a variable information description file. In this embodiment, the variable information description file can be an A2L file. The A2L file is a structured ASCII text file based on the ASAP2 standard, which is used to describe the calibration and measurement data of the electronic device (such as the automotive electronic control unit (ECU)) to which this method is applied. Then, the variable information description file is imported into the calibration tool. At the same time, the XCP gateway configuration tool is also needed to generate the application software engineering (such as Figure 2 This project includes the settings of the communication layer and protocol layer parameters of the XCP gateway, as well as the application software ID (for example Figure 2 In the example, application 1 ID=1, application 2 ID=2, application n ID=n), variable type and size, etc. Among them, the XCP gateway configuration tool specifies the layout of variables in the application in shared memory and generates skeleton code. The application developed based on this skeleton code will have the function of communicating with the XCP gateway and perform calibration measurements according to the agreed memory layout to communicate and exchange data with the ECU (engine control unit). The project file needs to include header files and source files for declaring and defining variables, as well as IPC communication related interfaces. Users can develop based on existing projects and deploy the compiled binary code files to the target object ( Figure 2 The target object shown is ECU), and the deployment of each target application in the target object is completed.

[0056] When the user needs to calibrate the shared memory corresponding to each target application, the user can use the calibration tool to generate calibration instructions based on the variable address information corresponding to these target applications in the A2L file, and then use the calibration tool to send the calibration instructions to the gateway that implements this method. If the number of calibration instructions generated at the same time is greater than 1, each of the calibration instructions can be sent to the gateway simultaneously or in sequence. Specifically, when the calibration tool starts calibration, it first needs to parse the variable information description file to obtain detailed information on all relevant variables in the target application, such as variable name, data type, address offset (address) in the shared memory, byte size, and possible scaling factor or offset (used to convert raw data into physical value). Then, based on the address offset (address) of each variable in the shared memory corresponding to the target application and the byte size of the variable in this information, the target position of each variable in the shared memory can be determined.

[0057] S102: Parse the calibration instruction, and determine a target location in the shared memory corresponding to the target application to be calibrated based on the parsing result.

[0058] When the gateway receives a calibration command from the calibration tool, it parses the calibration results, which may include the application ID of the calibration variable, as well as its address in shared memory, byte size, variable name, data type, and possible scaling factor or offset. The application ID here identifies the corresponding shared memory, and the address is the offset relative to the starting position of this shared memory. Based on the parsed application ID of the calibration variable, the address of the calibration variable in shared memory (the shared memory of the application corresponding to the calibration variable), and the byte size, the location of the desired calibration variable in shared memory can be determined and recorded as the target location.

[0059] S103: Calibrate and measure the target position based on the calibration instruction, and generate an instruction execution result.

[0060] After parsing the calibration instruction to determine the target location, the gateway ensures that a mapping relationship has been established with the shared memory maintained by the target application (this mapping relationship allows the XCP gateway to directly access specific addresses in shared memory). The corresponding variables at each target location in shared memory are calibrated based on the variable description information (variable name, data type, scaling factor or offset, etc.) obtained from parsing the calibration instruction. This typically involves locating the variable and writing the variable. Locating the variable: locating the specific location in shared memory where the variable is stored based on the address offset information in the variable information description file. Writing the data: writing the variable value in the variable information description file to the shared memory based on the data type and data size information in the variable information description file.

[0061] It can be seen from the above scheme that the present invention configures a shared memory for each target application, and uniformly writes the variable description information of each target application into a variable information description file. When the target application needs to be calibrated, a calibration instruction is generated based on the description information of each variable of the target application stored in the variable information description file. When the gateway applying this method obtains the calibration instruction, it parses the calibration instruction, determines the target position of each variable in the shared memory based on the parsing result, and then calibrates and measures the target position based on the parsing result. Therefore, only one variable information description file needs to be configured to complete the maintenance of the variable data of all target applications. When multiple target applications need to be updated, only the variable information description file needs to be updated, which simplifies the complexity of the management and maintenance of the variable information description file.

[0062] At the same time, when using the calibration tool to calibrate the shared memory of each target application, since the variable description information corresponding to each target application is stored in the same variable information description file, there is no need to frequently switch between different variable information description files, thereby improving the ability to measure and calibrate multiple target applications simultaneously in a single session, the measurement and calibration efficiency is extremely high, and the complexity and communication burden of the system are reduced.

[0063] In this embodiment, the type of gateway can be selected according to user needs. For example, the gateway in the embodiment of the present application can be an XCP gateway. When the gateway is an XCP gateway, in order to isolate variables between multiple target applications, the present invention extends the addressing method in the XCP protocol. The XCP calibration protocol stipulates that the variable address is represented by a 40-bit address, a 32-bit XCP address and an 8-bit extended address. In this addressing method, each target application is configured with a globally unique identity information (ID). The XCP gateway will create a shared memory corresponding to the identity information, such as Figure 3 By using the target application ID as the extended address and the offset address in the shared memory as the XCP address (the address is the address resolved in step S402 ), effective isolation and management of variables between different target applications can be achieved.

[0064] In the technical solution disclosed in this embodiment, the user can choose whether a target application uses the shared memory according to their own needs. Therefore, when there are multiple applications in the target object, there may be a target application that does not use the shared memory. Therefore, after obtaining the calibration instruction sent by the calibration tool, before determining the shared memory corresponding to the target application to be calibrated based on the parsing result, it is necessary to determine the identity information of the target application based on the parsing result of the calibration instruction. The identity information may refer to the ID corresponding to the target application. Then, based on the identity information, it is determined whether there is a shared memory corresponding to the target application. When there is a shared memory corresponding to the target application, the shared memory is calibrated and measured based on the variable description information of the target application stored in the variable information description file, and subsequent steps are performed. When there is no shared memory corresponding to the target application, the calibration instruction is not responded to or a negative response is returned.

[0065] In this embodiment, an additional IPC connection needs to be established between the target application and the gateway. After the variable data of the target application in the shared memory is calibrated, the gateway will notify the target application to read the variables in the shared memory and synchronously update the variables in its stack to synchronize the variables in the shared memory. The specific steps are as follows: Figure 4 As shown:

[0066] Step S401: monitoring the connection request of the target application.

[0067] In this step, the target application automatically initiates a connection request to the gateway that applies this method after startup. When the gateway monitors the connection request, it continues to execute subsequent steps.

[0068] Step S402: establishing shared memory communication of the target application based on the connection request.

[0069] When the gateway using this method monitors the connection request of the target application, it establishes shared memory communication with the target application. The shared memory is a mapping of the calibration variables of the target application.

[0070] Step S403: synchronously updating the variable data in the shared memory corresponding to the target application and the variable data inside the target application.

[0071] In this step, after the shared memory communication of the target application is established, the variable data in the shared memory can be assigned values through the variables of the target application. Specifically, during the user's use of the target software, the variable data inside the target software is monitored. When it is detected that the variables inside the target software have changed, the values of the changed variables are sent to the gateway, so that the gateway updates the variables in the shared memory according to the values, thereby keeping the variables in the shared memory synchronized with the variables in the target application. Specifically, the process may include: determining whether the value of the variable data within the target application has changed, and when it has changed, updating the variable data in the shared memory corresponding to the target application based on the variable data within the target application; of course, in this step, after the shared memory communication of the target application is established, the variable data in the target application may also be assigned values through the variables in the shared memory. Specifically, during the user's use of the target software, the variable data in the shared memory is monitored, and when a change is detected in the variable data in the shared memory (the change is not caused by the synchronization of the variable data in the shared memory and the variable data in the target software), the value of the changed variable is sent to the target application, so that the target application updates the variable data therein according to the value, thereby keeping the variables in the shared memory synchronized with the variables in the target application.

[0072] In distributed or embedded systems, shared memory serves as an efficient inter-process communication mechanism. Its creation and deallocation are typically handled by a gateway, while target applications only have access permissions. Because shared memory is a critical resource, mutual exclusion is required for shared memory access. To ensure mutual exclusion and prevent data races and inconsistencies, synchronization mechanisms such as semaphores and mutexes are used.

[0073] In a technical solution disclosed in another embodiment of the present application, when it is necessary to correct the variable parameters of the target application, the variable parameters of the target application in the shared memory can be directly corrected without starting the target application. When the target application is started, the variable value in the shared memory is assigned to the shared memory. Therefore, in the above solution, it is judged whether the value of the variable data in the shared memory corresponding to the target application has changed. When it has changed, the variable data inside the target application is updated based on the variable data in the shared memory corresponding to the target application. It can include: judging whether the value of the variable data in the shared memory corresponding to each target application has changed. When there is variable data that has changed, judging whether the target application corresponding to the variable data has established shared memory communication with the shared memory. When shared memory communication has not been established, generating and storing prompt information corresponding to the target application. When it is detected that shared memory communication with the target application has been established, responding to the prompt information, assigning the variable data in the shared memory to the target application. In addition, when it is detected that a target application establishes shared memory communication, it can be determined whether there is corresponding prompt information. If there is the prompt information, the variable data in the shared memory is assigned to the target application in response to the prompt information.

[0074] Based on the above solutions, this application has the following advantages:

[0075] Expand the variable addressing mode of the XCP protocol, and represent the variable address by combining the target application ID and the offset address in the shared memory, thereby achieving effective isolation and management of variables between different target applications;

[0076] By utilizing the shared memory mechanism, calibration measurements of multiple target applications can be achieved, ensuring efficient access and synchronization of calibration data;

[0077] By using the XCP gateway to centrally manage the calibration measurements of multiple target applications, all target applications within the ECU are abstracted as a unified slave node, achieving centralized and standardized calibration management.

[0078] The variables of the target application are configured with the help of the XCP gateway configuration tool, and the variable descriptions of multiple application software are integrated into one A2L file through the extended XCP address scheme, thereby simplifying the management and use of calibration data.
