[0030] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention. In traditional hardware-in-the-loop simulation scenarios, in order to test a specific ECU such as the ABS algorithm, it is often necessary to simultaneously activate multiple CAN buses connected to the ABS module, and the load rates of these buses are relatively high, which leads to the challenge of high CPU load in each measurement window of the automotive bus tool software, because each window needs to process all messages received on the CAN bus.

[0031] After adding a traditional filter to Graphics Window A and configuring the filter conditions for the signals to be observed by the ABS module, if the user needs to observe a portion of the signals already observed in Graphics Window A (for example, four wheel speed signals) in another measurement window, such as Graphics Window B, a numerical window, a panel window, or a signal value window, the user needs to add a traditional filter and configure the relevant data filter conditions before each measurement window to be observed. Because these data filter conditions are different from those in Graphics Window A, repeated configuration is time-consuming and error-prone, affecting the test process.

[0032] Therefore, at least one embodiment provides a method for implementing a measurement data filter, comprising: setting an upstream data stream input port, a downstream data stream output port, and a filtering function for each measurement window;

[0033] Each measurement window upstream data flow input port is connected to a measurement window downstream data flow output port or data source outside its own measurement window, forming a hierarchical connection;

[0034] Each layer of measurement window receives data from the upper layer measurement window through its upstream data flow input port, filters the received data, and then flows it out to the lower layer measurement window through its downstream data flow output port.

[0035] Compared with traditional filters that can only perform a single filtering function, each measurement window in the filter designed in the embodiment of the present disclosure is equivalent to a filter unit. A hierarchical connection is formed between the measurement windows, and each measurement window can be connected to multiple lower-level measurement windows. The hierarchical connection can pass the filtering results of the current measurement window to the lower layer, so that multiple measurement windows requiring the same filtering results do not need to repeatedly set the filtering function before each measurement window like traditional filters. There is no need to set up special filters between the measurement windows of each layer to achieve step-by-step filtering, thereby enabling complex data processing and data testing with minimal configuration, reducing the CPU consumption of the automotive bus tool software.

[0036] Various non-limiting implementations of the embodiments of the present disclosure are described in detail below with reference to the accompanying drawings.

[0037] As shown in FIG1 , some embodiments provide a method for implementing a measurement data filter, including:

[0038] Step S101, setting the upstream data flow input port, downstream data flow output port and filtering function for each measurement window;

[0039] Step S102 , each measurement window upstream data flow input port is connected to a measurement window downstream data flow output port or data source outside its own measurement window, forming a hierarchical connection;

[0040] In step S103, each measurement window receives data from the upper-layer measurement window via its upstream data stream input port, filters the received data, and then outputs it to the lower-layer measurement window via its downstream data stream output port. Specifically, a measurement window refers to a window that measures bus data. Measurement bus data can be displayed in various forms, such as graphical and textual displays. Graphical displays include, but are not limited to, graph windows and monitorable signal curves; and textual displays include, but are not limited to, message information windows and monitorable signal value changes.

[0041] In some embodiments, each measurement window is dynamically hierarchically connected to other measurement windows. Each measurement window can adjust its connection relationship with other measurement windows or data sources, so as to filter out the required data according to different usage requirements. In addition, the dynamic connection can quickly switch the upper-level connection of a measurement window, which allows the filtering results of the measurement window to be quickly switched, thereby improving the configuration efficiency of the filter and the modification efficiency of the filtering results.

[0042] The following, combined with the accompanying case drawings, explains in detail how each measurement window forms a dynamic hierarchical connection:

[0043] As shown in Figure 2, in the measurement settings window for the measurement data filter, the data source is the source of data for all filters at each layer. The C code editor is connected to the data source and is located at the first level; the graphics window is connected to the C code editor and is located at the second level.

[0044] As shown in Figure 3, the graphics window in Figure 2 can be dynamically dragged and connected to the data source, so that the graphics window and the C code editor are at the same level.

[0045] As shown in Figure 4, the graphics window in Figure 2 can also be dynamically dragged and connected to the CAN / CAN FD message information window, so that the graphics window remains at the second level but receives the filtered signal from the CAN / CAN FD message information window.

[0046] The following, combined with the accompanying application case, explains in detail how each measurement window forms a dynamic hierarchical connection:

[0047] As shown in Figure 5, during the vehicle test, engine-related messages are automatically sent through the "CAN / CAN FD Send" window. There are three frames in total, and their identifiers are: 0x064, 0x110, and 0x111.

[0048] As shown in Figure 6, a user may wish to display message information in the Trace window and only view the three frames of messages sent by the user, while filtering out other messages, such as those from the vehicle's ECU. To do this, simply create a new Trace window and, in the Measurement Data Filter's Measurement Settings window, drag this Trace window to the right of the "CAN / CAN FD Transmit" window, making it the lower measurement window for "CAN / CAN FD Transmit." The three frames of message information in the "CAN / CAN FD Transmit" window automatically become the filter criteria for the Trace window. This method eliminates the need to configure filters specifically for the Trace window, significantly improving filter configuration efficiency.

[0049] As shown in Figure 7, if the user wishes to view the message information corresponding to the gateway signal while filtering out other irrelevant information, the software system already has a gateway signal graph window "Gateway Signals". In this case, in the measurement settings window of the measurement data filter, simply drag the Trace window to the right of the "Gateway Signals" graph window to achieve the user's need, without having to design any filters for the Trace window.

[0050] As shown in FIG8 , during use, if the user still wants to view all message information and does not want to filter out any bus messages, the user only needs to drag the Trace window to the right of the "Data Source" in the measurement settings window of the measurement data filter, that is, to a position parallel to the "CAN / CAN FD Transmit" window and the "Gateway Signals" window to meet the user's needs without clearing any filters for the Trace window. In some embodiments, the method of setting the upstream data stream input port for each measurement window includes:

[0051] Set the data receiving callback function for each measurement window;

[0052] When the data receiving callback function is called, the measurement window reads the data flowing out of the upper measurement window from the parameters of the callback function.

[0053] An example is used to illustrate how to set the upstream data stream input port for the measurement window:

[0054] For example, in the window base class of the automotive CAN bus tool software written in C language, the data receiving callback function is set as follows:

[0055] void on_rx_frame(const ACAN:PCAN);

[0056] The data receive callback function has a parameter, ACAN, which is a pointer to a PCAN-type CAN message. When the data receive callback function is called by the vehicle bus tool system, the system assigns the pointer to the most recently received CAN message to the function parameter ACAN, thereby enabling the measurement window to read the CAN message content from the data receive callback function parameter.

[0057] Since the data receive callback function exists as the base class for all window types, it means that every measurement window supports calling this data receive callback function. Therefore, when data flows from the upper measurement window to the lower measurement window, the data receive callback function of the lower measurement window will be called, and the lower measurement window will be able to obtain the CAN message content flowing from the upper measurement window.

[0058] In some embodiments, the method of setting a downstream data flow output port for each measurement window includes:

[0059] Set the data distribution callback function list and data distribution program for each measurement window;

[0060] The data distribution callback function list includes: a data receiving callback function connected to all lower-level measurement windows of the current measurement window;

[0061] When data flows out of the current measurement window, the data distribution program calls the data receiving callback functions in the data distribution callback function list one by one.

[0062] An example is used to illustrate how to set the downstream data flow output port for the measurement window:

[0063] For example, in the window base class of the automotive CAN bus tool software written in C language, the data receiving callback function is set as follows:

[0064] bool rx_frame(const ACAN:PCAN);

[0065] Set the data distribution callback function list "dispatch_list", which is an array whose elements include the data receiving callback function pointers of all lower-level measurement windows connected to the current measurement window.

[0066] Set the data distribution callback function as follows:

[0067] void dispatch_frame(const ACAN:PCAN);

[0068] The data reception callback function and the data distribution callback function each have a parameter, ACAN, which is a pointer to a PCAN-type CAN message. When the data reception callback function and the data distribution callback function are called by the vehicle bus tool system, the system assigns the pointer to the most recently received CAN message to the parameters of the data reception callback function and the data distribution callback function, thereby enabling the measurement window to read the CAN message content from the parameters of the data reception callback function and the data distribution callback function.

[0069] The data receiving callback function is a function with a return value. The return value indicates whether the parameter data has passed the filtering of its own measurement window filter.

[0070] In the data distribution callback function code, the current measurement window first directly calls the data reception callback function of its own measurement window to trigger the current measurement window to filter the data. During the filtering process, if the data passes the filter of the current measurement window, the data reception callback function returns true, otherwise it returns false. If the data reception callback function returns true, the current measurement window then traverses the data distribution callback function list, calls each data reception callback function in the data distribution callback function list, and distributes the read CAN message content to the lower-level measurement windows. The data distribution program code is as follows:

[0071] Since the data receive callback function and the data distribution callback function exist as base classes for all window types, each measurement window supports calling these functions. Therefore, when data flows from the current measurement window to a lower-level measurement window, the current measurement window will distribute the data to all lower-level measurement windows connected to it. During this distribution process, the data distribution callback function will be called. The current measurement window will first call its own data receive callback function within the function to distribute the data flowing out of the current measurement window to each lower-level measurement window defined in the data distribution callback function list. In other words, each related lower-level measurement window can obtain the CAN message data flowing out of the current measurement window.

[0072] In some embodiments, a method for setting a filter function for each measurement window includes:

[0073] Extract the configuration content of the measurement window to form a filter entry;

[0074] Set up the comparison procedure;

[0075] When data flows into the measurement window, the comparison program first compares the incoming data with the filter items one by one, and the data that matches the comparison is allowed to flow out of the measurement window.

[0076] Taking the example of filtering the measurement window below the graphics window in the automotive CAN bus tool software, the following method is used to set the filter function for the measurement window:

[0077] First, extract all the signals in the graphic window and their corresponding channel numbers and message IDs to form a corresponding table as follows:

[0078] Then, based on the above correspondence table, identical message ID information is removed from the table to form a channel-ID correspondence table as follows. The entries in the channel-ID correspondence table are the filtering entries:

[0079] When the graphical window receives a CAN message from the upper-level measurement window, the comparison program first extracts the CAN message's channel number and message ID and compares them with the entries in the channel-ID correspondence table. Only when both the channel number and message ID match will the message pass through the graphical window filter and be passed to the lower-level measurement window. For example, a 0x33 message from channel 3 cannot find a corresponding entry in the correspondence table and therefore cannot pass the graphical window filter. However, a 0x300 message from channel 1 can pass the graphical window filter because it finds a corresponding entry in the second row of the correspondence table. In some embodiments, when a measurement window in any layer is deleted, the measurement window connected to it in the lower layer is moved to the same level as the deleted measurement window.

[0080] As shown in Figure 9, when the "CAN / CAN FD Transmit" measurement window is deleted, the lower-level measurement windows "Engine Speed" and "Engine Force" connected to this measurement window will be moved to the level of this measurement window, as shown in Figure 10.

[0081] In some embodiments, when the measurement data filter settings are reset, each measurement window will be reset to be directly connected to the data source.

[0082] Specifically, a case study is used to illustrate the changes before and after the measurement data filter settings are reset. As shown in Figure 11, before the measurement data filter settings are reset, each measurement window is set to be hierarchical connection. Click the reset icon in Figure 11 The measurement data filter settings can be reset. After reset, as shown in Figure 12, each measurement window is reset to connect to the data source.

[0083] Some embodiments further provide a data filtering method, comprising:

[0084] As shown in FIG13 , at least one data source window and at least one measurement window connected to the data source window are displayed through the measurement setting display interface. The upstream data flow input port of each measurement window is connected to a downstream data flow output port of a measurement window other than its own measurement window or a data source, forming a hierarchical connection. Each layer of measurement window receives data from the upper layer measurement window through its upstream data flow input port, filters the received data, and then flows it out to the lower layer measurement window through its downstream data flow output port.

[0085] The data filtering method further includes:

[0086] The configuration content of the corresponding measurement window is displayed after the command trigger area in each measurement window is triggered;

[0087] Specifically, as shown in FIG13 , after right-clicking the measurement window to trigger the instruction trigger area, click “Open Selected” to display the configuration content of the measurement window, as shown in FIG14 .

[0088] When any measurement window moves, it automatically forms connections with the corresponding upstream data stream input ports and downstream data stream output ports of other measurement windows;

[0089] By triggering the delete icon in the toolbar of the measurement data filter display interface Then, the selected measurement window is deleted and the lower measurement window of the deleted measurement window is moved to the level where the deleted measurement window is located;

[0090] By triggering the reset indicator in the toolbar of the measurement data filter display interface After that, reset each measurement window to be directly connected to the data source;

[0091] By triggering the expansion icon in the toolbar of the measurement data filter display interface Then, expand and display all measurement windows;

[0092] By triggering the measurement data filter display interface toolbar collapse indicator Then, collapse and hide all measurement windows; and

[0093] By triggering the connection mark between the upper and lower measurement windows Then, expand to show or collapse to hide the lower measurement window.
