[0003] In traditional hardware-in-the-loop simulation scenarios, to test a specific ECU, such as an ABS (Anti-lock Brake System) algorithm, multiple CAN (Controller Area Network) buses connected to the ABS module must be simultaneously activated. These buses are highly loaded, and each window must process all messages received on the CAN bus, which poses a high CPU load challenge for each measurement window in the automotive bus tool software. Summary of the Invention

[0004] The present invention relates to a method for implementing a measurement data filter, the method including: An upstream data stream input port, a downstream data stream output port, and a filter function are set for each measurement window. The upstream data stream input port of each measurement window is connected to the downstream data stream output port or data source of one measurement window other than the own measurement window, forming a hierarchical connection. Each layer measurement window receives data from an upper layer measurement window through its upstream data stream input port, and filters the received data before outputting it to a lower layer measurement window through its downstream data stream output port.

[0007] In order to clarify the objectives, technical aspects and advantages of the embodiments of the present invention, the technical aspects of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. However, it is clear that the described embodiments are only some of the embodiments of the present invention and do not represent all of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without performing creative work fall within the scope of protection of the invention.

[0008] In the conventional hardware-in-the-loop simulation scenario, to test a specific ECU, such as an ABS algorithm, multiple CAN buses connected to the ABS module must be activated simultaneously. The load on these buses is high, and each window must process all messages received on the CAN bus, which poses a high CPU load challenge for each measurement window in the automotive bus tool software.

[0009] After a user adds a conventional filter to graphic window A and sets the filtering conditions for the signals that the ABS module needs to observe, if the ABS module needs to further observe some of the signals observed in graphic window A (for example, four wheel speed signals) in other measurement windows such as graphic window B, numeric window, panel window, or signal value window, a conventional filter must be added in front of the measurement window that needs to be observed and related data filtering conditions must be set. Because these data filtering conditions are different from the data filtering conditions of graphic window A, the repeated configuration work is time-consuming and prone to errors, which will affect the test process.

[0010] Therefore, at least one embodiment provides a method for implementing a measurement data filter, which includes: setting an upstream data stream input port, a downstream data stream output port and a filter function for each measurement window. The upstream data stream input port of each measurement window is connected to the downstream data stream output port or data source of one measurement window other than the own measurement window, forming a hierarchical connection. Each layer measurement window receives data from an upper layer measurement window through its upstream data stream input port, and filters the received data before outputting it to a lower layer measurement window through its downstream data stream output port.

[0011] In contrast to conventional filters that can only perform a single filter function, each measurement window in the filter designed in the embodiment of the present disclosure corresponds to a single filter unit, and hierarchical connections are formed between the measurement windows, and each measurement window can be connected to multiple lower-level measurement windows. The hierarchical connections allow the filtering results of the current measurement window to be transmitted to lower levels. Multiple measurement windows that require the same filtering results do not need to repeatedly set a filter function before each measurement window as in conventional filters, and they can achieve hierarchical filtering without the need to install a separate filter between each layer of measurement windows. This allows complex data processing and data testing to be achieved with minimal configuration, reducing the CPU consumption of automotive bus tool software.

[0012] Various non-limiting embodiments of examples of the present disclosure are described in detail below with reference to the accompanying drawings. As shown in Figure 1, some embodiments provide a method for implementing a measurement data filter. The method includes: In step S101, an upstream data stream input port, a downstream data stream output port, and a filter function are set for each measurement window. In step S102, the upstream data stream input port of each measurement window is connected to the downstream data stream output port or data source of one measurement window other than the self measurement window to form a hierarchical connection. In step S103, each measurement window of each layer receives data from the upper layer measurement window through its upstream data stream input port, and after filtering the received data, outputs it to the lower layer measurement window through its downstream data stream output port.

[0013] Specifically, the measurement window is a window for measurement bus data, and the measurement bus data includes multiple display formats, such as graphic display and text display. The graphic display includes, but is not limited to, a graphic window, a monitorable signal curve, etc. The text display includes, but is not limited to, a message information window, a monitorable signal value change process, etc.

[0014] In some embodiments, the measurement windows are connected to other measurement windows through dynamic hierarchical connections, and the measurement windows can adjust the connection relationships with other measurement windows or data sources to filter corresponding required data according to different usage requirements. The dynamic connections also enable the upper-layer connections of a measurement window to be quickly switched, thereby quickly switching the filtering results of the measurement window, thereby improving the efficiency of filter placement and filtering result correction.

[0015] How each measurement window forms a dynamic hierarchical connection will be described in detail below with reference to the drawings. As shown in Figure 2, in the measurement setting window of the measurement data filter, the data sources are the data sources of all filters in each layer, the C code editor is connected to the data sources and is located on the first layer, and the graphic window is connected to the C code editor and is located on the second layer.

[0016] As shown in Figure 3, the graphic window in Figure 2 can be dynamically dragged and connected to a data source, which allows the graphic window and the C code editor to be in the same hierarchy.

[0017] As shown in Figure 4, the graphic window in Figure 2 can be dynamically dragged and connected to the CAN / CAN FD message information window, so that the graphic window is still in the second hierarchical level, but receives the filtered signal from the CAN / CAN FD message information window.

[0018] How each measurement window forms a dynamic hierarchical connection will be described in detail below with reference to the application example drawings. In the automotive test, the engine-related messages are automatically transmitted through the “CAN / CAN FD Transmit” window, as shown in Figure 5. There are three frames in total, and their identifiers are 0x064, 0x110, and 0x111, respectively.

[0019] As shown in Figure 6, during use, a user may want to open a Trace window to display message information, but only want to view the message information for the three frames they sent themselves, filtering out other messages, such as messages sent by an automobile ECU. To do this, a user simply creates a new Trace window and drags it to the right of the "CAN / CAN FD Transmission" window in the measurement settings window of the measurement data filter, making it a lower-level measurement window for "CAN / CAN FD Transmission." The message information for the three frames in the "CAN / CAN FD Transmission" window then automatically becomes the filtering condition for the Trace window. This method eliminates the need to specifically place a filter in the Trace window, thereby significantly improving filter placement efficiency.

[0020] During use, if the user wants to view the message information corresponding to the gateway signal and filter out other unrelated information, as shown in Figure 7, the software system already has a gateway signal graph window "Gateway Signals", and at this time, in the measurement setting window of the measurement data filter, the user can simply drag the Trace window to the right of the "Gateway Signals" graph window to achieve the user's needs, without having to design any filters for the Trace window.

[0021] As shown in Figure 8, if the user wants to view the entire message information during use, but does not want to filter any bus messages, in the measurement settings window of the measurement data filter, the user can simply drag the Trace window to the right of "Data Source," i.e., to a position parallel to the "CAN / CAN FD Transmit" window and the "Gateway Signals" window, without clearing any filtering for the Trace window.

[0022] In some embodiments, the step of configuring an upstream data stream input port for each measurement window includes: Set a data reception callback function for each measurement window. When the receive data callback function is called, the measurement window reads the data flowing from the upper measurement window from the parameters of the callback function.

[0023] As an example, the step of setting the upstream data stream input port in the measurement window will be described in detail. For example, in a window-based version of automotive CAN bus tool software written in C, the data reception callback function is set as follows: void on_rx_frame(const ACAN:PCAN) The data reception callback function has one parameter, ACAN, which is a CAN message pointer of PCAN type. When the data reception callback function is called by the automotive bus tool system, the system assigns the most recently received CAN message pointer to the parameter ACAN of the function, thereby enabling the measurement window to read the CAN message content from the parameter of the data reception callback function.

[0024] The data reception callback function exists as a base for all window types, which means that each measurement window supports calling the data reception callback function. Therefore, when data flows from an upper-layer measurement window to a lower-layer measurement window, the data reception callback function of the lower-layer measurement window is called, and the lower-layer measurement window can obtain the CAN message content flowing from the upper-layer measurement window.

[0025] In some embodiments, the step of configuring a downstream data stream output port for each measurement window includes: A data distribution callback function list and a data distribution program are set for each measurement window. The data delivery callback function list includes the data reception callback functions of all lower layer measurement windows currently connected to the measurement window. As data flows out of the current measurement window, the data delivery program calls each of the data reception callback functions in the data delivery callback function list.

[0026] An example will now be given to explain in detail the steps of setting the downstream data stream output port to a measurement window. For example, in a window-based version of automotive CAN bus tool software written in C, the data reception callback function is set as follows: bool rx_frame(const ACAN:PCAN) The data delivery callback function list is set to "dispatch_list", which is an array whose elements contain the data reception callback function pointers of all lower layer measurement windows currently connected to the measurement window.

[0027] Set the data delivery callback function as follows: void dispatch_frame(const ACAN:PCAN) The data reception callback function and the data delivery callback function each have one parameter, ACAN, which is a CAN message pointer of PCAN type. When the data reception callback function and the data delivery callback function are called by the automotive bus tool system, the system assigns the most recently received CAN message pointer to the parameters of the data reception callback function and the data delivery 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 delivery callback function.

[0028] The data reception callback function is a function with a return value that indicates whether the parameter data has passed filtering by the self-measurement window filter.

[0029] In the data distribution callback function code, the current measurement window first directly calls the data reception callback function of its own measurement window, and the current measurement window triggers a data filtering process. During the filtering process, if the data passes through the current measurement window filter, the data reception callback function returns true; otherwise, it returns false. After 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 each lower measurement window. The data distribution program code is as follows: void dispatch_frame(const ACAN: PCAN) { int i; if (rx_frame(ACAN)){ for (i=0; i< dispatch_list_count; i++){ dispatch_list[i](ACAN); } } }

[0030] The data reception callback function and data distribution callback function exist as base functions for all window types, meaning that each measurement window supports the calling of the data reception callback function and data distribution callback function. Therefore, when data flows from the current measurement window to a lower-level measurement window, the current measurement window distributes the data to all lower-level measurement windows connected to the current measurement window. During the distribution process, the data distribution callback function is called. The current measurement window first calls its own data reception callback function in a function to distribute the data flowing from the current measurement window one by one according to each lower-level measurement window defined in the data distribution callback function list. Each associated lower-level measurement window can then obtain the CAN message data flowing from the current measurement window.

[0031] In some embodiments, the step of setting a filtering function for each measurement window includes: The layout contents of the measurement window are extracted to form a filter entry. Set up a matching program. When data flows into the measurement window, the matching program first matches the incoming data with the filter entries one by one, and allows data that matches the match to flow out of the measurement window.

[0032] Taking the graphic window of the automotive CAN bus tool software as an example, the step of setting the filtering function for the measurement window will be described in detail. First, all signals in the graphic window, the channel numbers corresponding to the signals, and message IDs are extracted, and a correspondence table is formed as follows: [Table 1] Next, based on the above correspondence table, the same message ID information in the table is removed to form a channel-ID correspondence table as follows: The entry contents in the channel-ID correspondence table are filter entries. [Table 2] When the graphic window receives a CAN message from the upper-layer measurement window, the matching program first extracts the channel number and message ID of the CAN message and matches them with the entries in the channel-ID correspondence table. Only if the channel number and message ID are the same can the CAN message be transmitted to the lower-layer measurement window through the graphic window filter. For example, the 0x33 message from channel 3 cannot pass through the graphic window filter because it cannot find a corresponding entry in the correspondence table. The 0x300 message from channel 1 can pass through the graphic window filter because it finds a corresponding entry in the second row of the correspondence table.

[0033] In some embodiments, when a measurement window in any layer is deleted, the lower layer measurement windows connected to it are moved to the layer in which the deleted measurement window is located. When the measurement window "CAN / CAN FD Transmission" is deleted as shown in Figure 9, the lower-level measurement windows "Engine Speed" and "Engine Force" connected to the measurement window are moved to the layer where the measurement window is located as shown in Figure 10.

[0034] In some embodiments, when the measurement data filter settings are reset, each measurement window is reset to be directly connected to a data source. Specifically, the following illustrates an example of the change before and after resetting the measurement data filter settings. As shown in Fig. 11, before resetting the measurement data filter settings, each measurement window is set to be hierarchically connected, and the reset indicator in Fig. 11

[0035] Some embodiments further provide a data filtering method, the method including: As shown in Figure 13, the measurement setting display interface displays a data source window and at least one measurement window connected to the data source window. The upstream data stream input port of each measurement window is connected to the downstream data stream output port or data source of one measurement window other than the self-measurement window, forming a hierarchical connection. Each layer measurement window receives data from an upper layer measurement window through its upstream data stream input port, and after filtering the received data, outputs it to a lower layer measurement window through its downstream data stream output port.

[0036] The above data filtering method further includes: After triggering the command trigger area in each measurement window, the layout contents of the corresponding measurement window are displayed. Specifically, as shown in Figure 13, right-click the measurement window to trigger the command trigger area, and then click "Open Selected" to display the layout contents of the measurement window, as shown in Figure 14.

[0037] When any measurement window moves, it forms an automatic connection with the corresponding upstream data stream input port and downstream data stream output port of the other measurement window. Delete indicator in the Measurement Data Filter display interface toolbar
