Specifically, the use of words such as "exemplary" or "for example" is intended to present related concepts in a specific way.
[0043] The data recording device internally includes a 1553B module, an AD acquisition function module, a discrete quantity acquisition module, an EMMC storage module and a network module.

[0045] At present, it is difficult to test the data recording device in the prior art, because the main function of the data recording device is to receive and record data from other systems or devices, rather than actively generate or send excitation signals. Therefore, the data recording device has no external excitation, is in a listening state in the bus, and does not output discrete quantities, analog quantities, etc., which makes it difficult to automate the testing of the data recording device.
[0046] In view of this, an embodiment of the present application provides a test method for a data recording device, in which a test device sends a first excitation signal to a data recording device, the first excitation signal carries a first moment, the data recording device obtains the first excitation signal and the first moment carried by the first excitation signal, generates a first data file and names the first data file according to the first moment, then the test device sends a second excitation signal to the data recording device, the second excitation signal carries multiple types of first test data, the data recording device obtains the second excitation signal and stores the multiple types of first test data carried by the second excitation signal in the first data file, the test device obtains the first data file from the data recording device and obtains the second test data from the first data file, and the test device compares the first test data of the same type with the second test data to obtain a test result. However, the test of the data recording device in the prior art is relatively difficult, because the main function of the data recording device is to receive and record data from other systems or devices, rather than actively generate or send excitation signals, so the data recording device has no external excitation, is in a listening state in the bus, and does not output discrete quantities, analog quantities, etc., which makes it difficult to automate the test of the data recording device. It can be seen that in the present application, a test device can be used to stimulate the data recording device and perform automated testing on the data recording device.
[0047] In order to make the technical solution of the present application clearer and easier to understand, a test method for a data recording device provided in an embodiment of the present application is introduced. Figure 1 As shown, the figure is a flow chart of a test method for a data recording device provided in an embodiment of the present application. The test method for the data recording device is executed by a test device, and the method includes:
[0048] S101. A testing device sends a first excitation signal to a data recording device.
[0049] The test device sends a first excitation signal to the data recording device through the 1553B module. The first excitation signal carries a first moment. The first moment carried by the first excitation signal is the moment when the first excitation signal is generated by the test device.
[0050] like Figure 2As shown, the figure is a schematic diagram of a test device provided in an embodiment of the present application, wherein the test device 200 internally includes a 1553B board 201, a discrete quantity board 202, a DA board 203, a parsing module 205 and a power supply module 204, wherein the 1553B board 201 is used for the test device to generate a 1553B bus excitation, and can simulate a BC (Bus Controller) and a RT (Romot Terminal), the discrete quantity board 202 is used for the test device to generate a discrete quantity excitation, the DA board 203 is used to generate an analog quantity excitation, the parsing module 205 is used to restore the data file to obtain data, and the power supply module 204 is used to power the data recording device.
[0051] The stimulus signal is a signal used to trigger or start a device, process or reaction. The first stimulus signal carries a key piece of information, namely the first moment, which is the specific time point at which the data recording is triggered. The first moment is crucial for the subsequent data analysis and processing, because the first moment is the key information for the test device to find the first data file in the data recording device.
[0052] S102: A data recording device generates a first data file according to a first moment carried by a first excitation signal.
[0053] The file name of the first data file is the first moment.
[0054] When the data recording device receives the first excitation signal, the data recording device can parse the first excitation signal to the first moment, then generate a first data file, store the first excitation signal and the first moment carried by the first excitation signal in the first data file, and name the file name of the first data file as the first moment. The first data file is used to store multiple types of first test data in the second excitation signal sent by the test device to the data recording device, and the first data file is named with the first moment so that the test device can search for the first data file in the data recording device.
[0055] S103: The testing device sends a second excitation signal to the data recording device.
[0056] The second excitation signal carries multiple types of first test data, including 1553B bus data type, discrete data type and analog data type. The purpose of the test device sending the second excitation signal to the data recording device is to test whether the data recording device can normally collect the first test data.
[0057] The test device 200 has a 1553B board 201 inside, which is used to output 1553B bus data. The test device 200 can schedule all 10 1553B messages such as BC-to-RT and RT-to-BC according to the 1553B data format. The test device stimulates the 10 messages and can control the number of messages sent, the sending interval, the data length, etc. The generated 1553B bus data is sent to the data recording device as the second excitation signal, and the 1553B module in the data recording device collects and records according to the second excitation signal.
[0058] There is a discrete quantity board 202 inside the test device 200, which is used to output discrete quantity signals, that is, output 28V open circuit signals or ground / open circuit signals. The test device 200 outputs the 28V open circuit or ground / open circuit signals in turn, only outputs one valid signal each time, and then makes the 28V open circuit or ground / open circuit signal invalid, that is, both the validity and invalidity of the 28V open circuit or ground / open circuit signals are tested for collection and recording by the discrete quantity acquisition module in the data recording device.
[0059] The test device 200 has a DA board 203 inside, which is used to output analog signals, that is, it can realize the conversion of digital quantities into analog quantities, including 28V analog signals and 5V analog signals. The test device 200 outputs the 28V analog signals and 5V analog signals in turn, and only outputs the 28V analog valid signal or the 5V analog valid signal each time, and then makes the 28V analog valid signal or the 5V analog valid signal invalid, that is, the validity and invalidity of the 28V analog signal and the 5V analog signal are tested for collection and recording by the AD acquisition function module in the data recording device.
[0060] S104. The data recording device stores the multiple types of first test data carried by the second excitation signal in a first data file.
[0061] The data recording device collects and records the second excitation signal, and stores multiple types of first test data carried by the second excitation signal into a first data file, wherein the first test data includes 1553B bus data, discrete quantity data and analog quantity data.
[0062] S105: The testing device searches the data recording device to see whether there is a first data file corresponding to the first moment.
[0063] The data recording device is connected to the test device through a network module, and the test device and the data recording device are in the same network segment. The network module includes an FTP server. The test device logs in to the FTP server through the address, user name and password to search and download the first data file.
[0064] If the testing device can find the data file with the file name of the first moment in the data recording device, it means that the data file is the first data file;
[0065] If the testing device cannot find the data file with the file name of the first moment in the data recording device, it means that the data file is not the first data file.
[0066] If the search result indicates that the first data file corresponding to the first moment does not exist in the data recording device, S106 is executed; if the search result indicates that the first data file corresponding to the first moment exists in the data recording device, S107 is executed.
[0067] S106: If the search result indicates that the first data file corresponding to the first moment does not exist in the data recording device, a test result indicating that the data recording device is abnormal is obtained.
[0068] If the test device cannot find the first data file corresponding to the first moment in the data recording device, it indicates that the data recording device has not collected the first excitation signal and the first moment carried by the first excitation signal, so the test device obtains an abnormal test result of the data recording device.
[0069] S107: If the search result indicates that the first data file corresponding to the first moment exists in the data recording device, obtain multiple types of second test data from the first data file.
[0070] The test device 200 calls the parsing module 205 to parse the first data file obtained from the data recording device, and obtains second test data from the first data file. The second test data includes three types of data: 1553B bus data, discrete data and analog data.
[0071] S108: The testing device determines whether the data recording device is normal according to the first test data and the second test data that belong to the same type.
[0072] The testing device 200 compares the first test data and the second test data which are of the same type to obtain a comparison result.
[0073] Exemplarily, the 1553B bus data of the first test data is compared with the 1553B bus data of the second test data, and the comparison is performed one by one according to the recording format of the 1553B bus data: header word + data length + data content + data check; the discrete data of the first test data is compared with the discrete data of the second test data, and the comparison is performed one by one according to the recording format of the discrete data: header word + data content + data check; the analog data of the first test data is compared with the analog data of the second test data, and the comparison is performed one by one according to the recording format of the analog data: header word + data content + data check.
[0074] If the contents of the 1553B bus data of the first test data are consistent with the contents of the 1553B bus data of the second test data, the discrete data of the first test data are consistent with the discrete data of the second test data, or the analog data of the first test data are consistent with the analog data of the second test data, execute S109.
[0075] If the contents of the 1553B bus data of the first test data are inconsistent with the contents of the 1553B bus data of the second test data, the discrete data of the first test data are inconsistent with the discrete data of the second test data, or the analog data of the first test data are inconsistent with the analog data of the second test data, execute S110.
[0076] S109: If the comparison result indicates that the first test data and the second test data of the same type are consistent, a normal test result of the data recording device is obtained.
[0077] If the testing device compares the first test data and the second test data one by one and obtains a result that the first test data and the second test data are consistent, it indicates that the data recording device normally obtains the second excitation signal and multiple types of first test data, and stores the second excitation signal and multiple types of first test data completely in the first data file, so the testing device obtains a normal test result of the data recording device.
[0078] S110: If the comparison result indicates that the first test data and the second test data of the same type are inconsistent, a test result indicating that the data recording device is abnormal is obtained.
[0079] If the testing device compares the first test data and the second test data one by one and obtains an inconsistent result between the first test data and the second test data, it indicates that the data recording device has not obtained or has not completely obtained the second excitation signal and multiple types of first test data, so the testing device obtains an abnormal test result of the data recording device.

However, the test of the data recording device in the prior art is more difficult, because the main function of the data recording device is to receive and record data from other systems or devices, rather than actively generate or send excitation signals, so the data recording device has no external excitation, is in a listening state in the bus, and does not output discrete quantities, analog quantities, etc., which makes it difficult to automate the test of the data recording device.
