Therefore, after the test tool receives the serial port data message sent by the computer, it first looks for the data header identifier 0xA5, then intercepts the data according to the fixed length of 64 bytes, checks the second last byte of the data message, and determines whether it is the data tail identifier 0x5A. If both the header identifier and the tail identifier are correct, then enter the data consistency check process.

[0070] In one embodiment, the message positions in the preset message transmission sequence include: a fifth offset position to a sixth offset position;

[0077] If the total check code is consistent with the message check value, the check is passed.

[0078] In specific implementation, the first check code information and the second check code information are data with offsets of 1 and 63 bytes. All data from offset 2 to offset 61 of the data message (data between the fifth offset position and the sixth offset position) are summed in hexadecimal to obtain the message check value, and the check value is compared with the obtained total check code. If they are equal, it means that the data message is correct and no error occurs during the transmission process; otherwise, this check is wrong and all data is discarded.

[0079] In one embodiment, if the verification is passed, a circuit board function test is performed according to the serial port data message to obtain a test result message, including:

[0089] Step 206: Verify the message check value of the test result message according to the first check code information and the second check code information.

[0090] Depend on Figure 2As shown, it can be known that the embodiment of the present invention sends a serial port data message to the test tooling through the computer terminal; receives the test result message fed back by the test tooling; verifies the message identification information in the test result message according to the message identification position in the preset message transmission sequence; if the verification passes, determines the first verification code information and the second verification code information of the test result message according to the verification code position in the preset message transmission sequence, and the verification code position includes: a first offset position and a second offset position, wherein the first offset position corresponds to the first verification code information, and the second offset position corresponds to the second verification code information; determines the message verification value of the test result message according to the message position in the preset message transmission sequence; verifies the message verification value of the test result message according to the first verification code information and the second verification code information.

[0091] In one embodiment, the message identification position includes: a third offset position and a fourth offset position;

[0105] Figure 3 FIG. 1 is a flow chart of circuit board function test in a specific embodiment of the present invention. Figure 3 As shown, after the test fixture is powered on, the serial port signal, SPI signal, digital quantity, analog quantity, and encoder signal are checked and initialized, and the standby state is entered to wait for receiving external serial port data messages. The SPI is a full-duplex synchronous serial communication master station, which actively sends data signals and synchronously receives slave reply data signals. After the IO board is powered on, the SPI signal, digital quantity, analog quantity, and encoder signal are checked and initialized, and the standby state is entered to wait for receiving external SPI data messages. The SPI is a full-duplex synchronous serial communication slave station, which passively receives the master station data signal and synchronously sends the data signal. The computer and the test fixture are connected via a DB9 cable, and data is sent and received via RS232 communication. The test fixture and the IO board are connected via a DB44 cable, where the DB9 cable signal definition is shown in Table 1 and the DB44 cable signal definition is shown in Table 2.

[0108] Table 2

[0109]

[0110]

[0111] The computer sends a data message of a specific format to the test fixture via RS232. After receiving the serial port message, the test fixture saves it to the local memory and caches the data. After receiving the serial port data interruption, check whether the message data length is greater than 1 complete message structure length. If it is greater than 1 complete message length, check whether the cached data contains a specific message header identifier 0xA5. If it is not a message header identifier, discard the current data and check whether the next byte data is a message header. If it is a message header identifier, check whether the message tail data is equal to the specific message header identifier 0x5A according to 1 complete message structure length. If not, discard the current data and check whether the next byte data is a message header. Until the message header and message tail of the current data are equal to the specific identifier, the data message is considered correct, and valid data is ready to be received, and the next step is performed. The definition of the serial port data message is shown in Table 3.

[0112] Table 3

[0113]

[0114]

[0115] When the data message is correct, split the current message data according to the message definition. Configure the digital input and output signals, and output the digital output signals according to the message command. Output the analog output signal and the encoder signal, and the corresponding signal will be connected to the IO board through the DB44 cable as the signal source of the IO board. Then the test fixture sends the SPI data message to the IO board. After the IO board receives the SPI message, it synchronously sends the SPI data to the test fixture. Then read the digital input, analog input, and calculate the encoder through the DB44 cable. Output the digital output and analog output, and the corresponding signal will be connected to the test fixture through the DB44 cable as the signal source of the test fixture. The test fixture reads the digital input and analog input through the DB44 cable. Then splice the digital input, analog input, and SPI slave reply message, and send it to the computer through the DB9 serial port data. After receiving the serial port data replied by the test fixture, the computer checks the message header, message tail, and message length. If the message verification passes, the data comparison verification is performed. If it passes, this test passes. If the data comparison check fails, the serial port data will be retransmitted. If the data check error exceeds 10 times, the test fails.

[0116] In the specific implementation, in order to ensure the correctness of the received data, the check code is stored and transmitted in two sections. After the data header identifier 0xA5 is transmitted, the first section check code 1 is sent immediately, then all data messages are transmitted, and finally the data tail identifier is sent, followed by the second section check code 2. After receiving the data message, the data message receiver first looks for the data header identifier 0xA5, then intercepts the data according to the fixed length of 64 bytes, checks the second last byte of the data message, and determines whether it is the data tail identifier 0x5A. If both the header identifier and the tail identifier are correct, then the data consistency check process is entered. The data with offset 1 and offset 63 bytes is the check value 1 of this message data. All data from offset 2 to offset 61 of the data message are summed in hexadecimal as the data check value of this data message, and the check value is compared with the read message data check value 1. If they are equal, it means that the data message is correct and no error occurs during the transmission process; otherwise, this check is wrong and all data is discarded.

[0117] A specific embodiment is given below to illustrate the specific application of the circuit board function test in the embodiment of the present invention. In this specific embodiment, the circuit board function test is performed according to the following steps:

[0118] Step 1: Prepare the computer, test fixture and circuit board to be tested, connect DB9 and DB44 cables, and make sure all devices are powered, and enter the test preparation process.

[0119] Step 2: The computer sends a serial port data message to the test fixture. The serial port data message is as follows: A5 1E 00 00FF0000F5 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 5A27.

[0120] Step 3: The test tool enters the standby state and waits to receive the serial port data message;

[0121] Step 4: After receiving the above message, the test tool first checks whether the data at offset 0 is 0xA5. If the check is correct, go to step 5; otherwise, return to step 3;

[0122] Step 5: Test whether the data of the tooling detection offset 33 is 0x5A. If the detection is correct, go to step 6; otherwise, return to step 3;

[0123] Step 6: Perform hexadecimal sum calculation on the data of offset 2 to 61, and the sum result is 0x1E27; compare the result with the data of offset 1 and offset 63. If the detection is correct, go to step 7; otherwise, return to step 3;

[0124] Step 7: Continue to perform data splitting, configure the test fixture according to the digital input and output, output digital output, analog output and encoder signal, and send SPI data message. Then receive SPI data message, read digital input and analog input signals, splice the data, and send it to the computer through the serial port.
