[0044] Figure 2 It is a flowchart of the three-self inertial group ground test method based on the MFC framework of the present invention. DETAILED DESCRIPTION OF THE EMBODIMENTS

[0045] See Figure 1, this embodiment discloses a three-self inertial unit ground test system based on the MFC framework. The system includes a parameter input module, an initialization module, a periodic data acquisition module, a data parsing module, a data calculation module, a calculation result output module, and a view module built based on the MFC framework. This embodiment uses the MFC framework as the general framework for the three-self inertial unit ground test software because currently, the software implementations of various types of three-self inertial unit products are based on the MFC framework, and the MFC framework is adopted to maintain continuity. The parameter input module includes multiple parameter input sub-modules corresponding to each test item, which are used to set the parameters required for the test. The parameters include one or more of the acquisition period, the number of acquisition groups, longitude and latitude, and altitude. The initialization module includes multiple initialization sub-modules corresponding to each test item. The initialization sub-module initializes the data file, the parameters used in the calculation process of each corresponding test item, and the communication interface according to the parameters set by the corresponding parameter input sub-module. The communication interface includes a serial port, a 1553b board, a CAN bus interface, or a network port. The serial port includes different serial ports such as 232 and 422.

[0046] The periodic data acquisition module includes multiple periodic data acquisition sub-modules corresponding to each test item. Each periodic data acquisition sub-module performs data acquisition according to the initialized data file, parameters, and communication interface of the initialization sub-module. The periodic data acquisition sub-module includes a data acquisition start unit, a data acquisition pause unit, a data acquisition resume unit, and a data acquisition end unit. The data acquisition start unit is used for acquisition start and data acquisition. The data acquisition pause unit and the data acquisition resume unit are respectively used to control the pause and resume of data acquisition. The data acquisition end unit is used to end the data acquisition process after acquiring multiple groups of data of the preset number of cycles.

[0047] In the process of transmitting each group of data collected by the periodic data acquisition sub-module to the data parsing module, the technology of sending custom windows messages is adopted, and a queue caching mechanism is established during the transmission process. The data parsing module is used to synchronously receive the data collected by the data acquisition start unit and the data acquisition resume unit and perform parsing to judge the product status of the data report. The original data collected by the data acquisition start unit and the data acquisition resume unit is saved, and a write data queue cache is established during the saving process to effectively utilize the receiving time gap for data persistence, avoid frequent access to the hard disk, and reduce the CPU occupancy rate.

[0048] The data calculation module receives the data that meets the preset number of groups collected by the periodic data acquisition module, performs calculations, and outputs the calculation results to the calculation result output module; the data calculation module includes multiple data calculation sub-modules, and each data calculation sub-module corresponds to the data processing logic of each test item, and the data processing logic of each test item is implemented using the virtual function mechanism of C++ to facilitate modification and customization; each data calculation sub-module can be connected to each different periodic data acquisition sub-module to implement switching of the communication interface of the periodic data acquisition sub-module without changing the data processing logic of the test item corresponding to the data calculation sub-module, so as to switch different communication logics.

[0049] The view module includes multiple view sub-modules corresponding to each test item. The view sub-module is used to give each test item its own independent view interface, and the view interface is designed modularly; the view sub-module adopts a flow layout algorithm to adapt the view interface to the screen, so as to ensure that the software is applicable to various screen sizes without losing usability.

[0050] The calculation result output module is used to output the calculation results in the required form. The calculation result output module performs real-time plotting based on the calculation results and displays them on the view interface to view the data trends of the test results (for example, accelerometer, gyroscope, temperature control).

[0051] The three-self inertial group ground test system based on the MFC framework provided in this embodiment also has a newly added log function for the framework, which can record test items, test time, etc., for convenient reference.

[0052] See Figure 2 , the test method of the above three-self inertial group ground test system based on the MFC framework includes the following steps:

[0053] S1. Based on the parameter input sub-module corresponding to the current test item, input the parameters corresponding to the current test item, and the parameters include one or more of the acquisition period, the number of acquisition groups, longitude, latitude, and altitude.

[0054] S2. Switch the view interface to the view corresponding to the current test item.

[0055] S3. According to the parameters input in step S1, perform initialization through the initialization sub-module corresponding to the current test item. The initialization includes initializing the data file, the parameters used in the calculation process of each corresponding test item, and the communication interface; the communication interface includes a serial port, a 1553b board, a CAN bus interface, or a network port.

[0056] S4. According to the communication logic required by the current test item, select the periodic data acquisition sub-module corresponding to the corresponding communication interface. The periodic data acquisition sub-module acquires multiple groups of data according to the acquisition period and transmits them to the data parsing module. Specifically, the transmission of each group of data acquired by the periodic data acquisition sub-module to the data parsing module is carried out by using the technology of sending custom Windows messages, and a queue caching mechanism is established during the transmission process; the data parsing module synchronously parses each group of acquired data. In this embodiment, the acquisition period refers to the acquisition period duration input when the parameters are input, and multiple groups of data are based on the required number of input acquisition groups. For example, if the acquisition period is set to 1 second, then each time the data within 1 second is acquired is a group. If 50 groups are set, then after acquiring the data within 1 second, calculations are performed, and after acquiring 50 groups of data, summary calculations are carried out.

[0057] Taking the selection of the serial port as the corresponding communication interface for data acquisition as an example:

[0058] When the current test item uses the serial port as the communication interface, the data acquisition start unit needs to create and start a data acquisition thread, and in this thread, the serial port data is read by calling the Windows API WriteFile; for the serial port data acquisition, the data acquisition pause unit switches the thread execution to the spin state to stop reading the serial port data; for the serial port data acquisition, the data acquisition resume unit ends the thread spin state; the data acquisition end unit ends the data acquisition thread. The data calculation sub-module corresponding to the current test item can obtain the test results of the current test item under the communication logic of the 1553b board card by only switching the periodic data acquisition sub-module to the communication logic of the 1553b board card without adjusting the data processing logic of the data calculation sub-module.

[0059] The data parsing module judges according to the product status reported by the parsed data frame. If the product status reported by the data frame is incorrect, the test ends; if the product status reported by the data frame is normal, go to step S5; in this embodiment, the parsed data during the test process is monitored for out-of-tolerance, and each parameter with an out-of-tolerance event is classified into three levels: Normal, Warning, and Error according to the severity level for setting ranges. At the same time, the start time and end time of each test are recorded through the logging function to facilitate understanding the progress of the test; for each out-of-tolerance event of each index, there is a designed indicator light for indication, showing green when it is Normal, yellow when it is Warning, and red when it is Error.

[0060] S5. After each group of data is parsed, it is passed to the data calculation sub-module corresponding to the current test item, and the data calculation sub-module performs data calculations according to the data processing logic corresponding to the current test item; the calculation results are output on the view interface through the calculation result output module.

[0061] S6. Determine whether the current test item requires switching the communication logic. If it is necessary to switch the communication logic, return to step S1 until the current test item does not require switching the communication logic, and the test of the current test item ends; if it does not require switching the communication logic, the test of the current test item ends.

[0062] Take the data acquisition with the switched corresponding communication interface being the 1553b board as an example:

[0063] For the current test item using the 1553b board as the communication interface, for the data acquisition start unit with respect to the 1553b, it is necessary to switch the board to the active mode and register an interrupt callback function. When the board acquires the set number of data groups, this callback function will be called, and in this function, the application layer interface of the board is called to read the data; for the data acquisition pause unit with respect to the 1553b, the board is switched back from the active mode to the BC working mode; the data acquisition resume unit switches the board from the BC mode back to the active mode; the data acquisition end unit switches the board from the active mode back to the BC mode; similarly, for the data calculation sub-module corresponding to the current test item, without adjusting the data processing logic of the data calculation sub-module, only the communication logic of the periodic data acquisition sub-module is switched to the serial port to obtain the test result of the current test item under the communication logic of the serial port.

[0064] S7. Use the same operations as in steps S1 - S6 to test other test items of the three-self inertial unit and obtain the test results of the three-self inertial unit.
