[0067] Example 1

[0068] This embodiment provides a BMS auxiliary testing method, such as Figure 1 As shown, the steps include:

[0069] S1. When the trigger condition is met, the host computer sends a simulated BMS test signal to the universal test mainboard unit.

[0070] S2. The BMS to be tested receives a simulated BMS test signal.

[0071] S3. After the BMS to be tested completes the service test according to the BMS test signal, the BMS to be tested and the general test mainboard upload the BMS test results to the host computer respectively.

[0072] In actual application scenarios, BMS includes: BAMS, BCMS, EMMU, so in this embodiment, auxiliary tests of the above three devices are included. Next, combined with the specific implementation process, the auxiliary test processes of the three devices are described respectively:

[0073] BAMS assisted testing method:

[0074] like Figure 2 As shown, the simulated BAMS test signal includes: a simulated BAMS first test signal, a simulated BAMS second test signal, and a simulated BAMS third test signal.

[0075] First, the host computer pre-sets the automatic trigger conditions. If the automatic trigger conditions are met, the host computer sends the simulated BAMS first test signal to the universal test mainboard unit; if the automatic trigger conditions are not met, the host computer judges the return signal of the universal test mainboard. The automatic trigger conditions include: a timing trigger signal, that is, when the set time is reached, a timing trigger signal is automatically generated for testing.

[0076] Furthermore, if the return signal is a request signal of the BAMS to be tested, the host computer sends a simulated BAMS second test signal to the universal test mainboard unit; if the return signal is not a request signal of the BAMS to be tested, the host computer sends a simulated BAMS third test signal to the universal test mainboard unit.

[0077] When the BAMS to be tested receives the simulated BAMS first test signal, the simulated BAMS second test signal, or the simulated BAMS third test signal, the service test is started. When the BAMS to be tested performs the service test, the BAMS to be tested determines whether it is necessary to simulate the BAMS second test signal.

[0078] Specifically, the BAMS to be tested determines whether it needs to request the simulation device to send some signals based on the received signal and protocol content, and reports it to the universal test mainboard if necessary, and the test mainboard reports it to the host computer.

[0079] If it is necessary to simulate the second BAMS test signal, the BAMS to be tested sends a request signal to the universal test mainboard unit. After the BAMS to be tested completes the service test based on the simulated BAMS first test signal, the simulated BAMS second test signal, and the simulated BAMS third test signal, the BAMS to be tested reports the BAMS test result to the host computer. If it is not necessary to simulate the second BAMS test signal, after the BAMS to be tested completes the service test based on the simulated BAMS first test signal and the simulated BAMS third test signal, the universal test mainboard unit receives the BAMS test result and uploads it to the host computer. Finally, the host computer outputs the corresponding test report based on the BAMS test results reported by the BAMS to be tested and the BAMS test results uploaded by the universal test mainboard unit, completing the entire EMMU auxiliary test process.

[0080] In this process, if the BAMS to be tested does not receive the simulated BAMS first test signal, the simulated BAMS second test signal, or the simulated BAMS third test signal, and the host computer does not receive the BAMS test result within the set time, it means that the test has failed, and the host computer outputs the corresponding test failure report. If the host computer receives the BAMS test result within the set time, the test continues. Preferably, the set time can be 3 seconds.

[0081] BCMS auxiliary test method:

[0082] like Figure 3 As shown, the simulated BMS test signal includes: a simulated BCMS first test signal, a simulated BCMS second test signal, and a simulated BCMS third test signal. The host computer simulates the communication protocol and communication interface of the actual device.

[0083] The host computer pre-sets the automatic trigger conditions. If the automatic trigger conditions are met, the host computer sends the simulated BCMS first test signal to the universal test mainboard unit; if the automatic trigger conditions are not met, the host computer judges the return signal of the universal test mainboard.

[0084] Furthermore, if the return signal is a request signal of the BCMS to be tested, the host computer sends a simulated BCMS second test signal to the universal test mainboard unit; if the return signal is not a request signal of the BCMS to be tested, the host computer sends a simulated BCMS third test signal to the universal test mainboard unit.

[0085] Subsequently, determine whether the test mainboard unit needs to output the simulated BCMS first test signal, the simulated BCMS second test signal, and the simulated BCMS third test signal; if the test mainboard unit needs to output the simulated BCMS first test signal, the simulated BCMS second test signal, and the simulated BCMS third test signal, the universal test mainboard unit outputs the simulated BCMS first test signal, the simulated BCMS second test signal, and the simulated BCMS third test signal according to the instruction, and sends the simulated BCMS first test signal, the simulated BCMS second test signal, and the simulated BCMS third test signal to the BCMS to be tested through the CAN interface of the universal test mainboard unit; if the universal mainboard test unit does not need to output the simulated BCMS first test signal, the simulated BCMS second test signal, and the simulated BCMS third test signal, then the simulated BCMS first test signal, the simulated BCMS second test signal, and the simulated BCMS third test signal are forwarded to the BCMS to be tested through the CAN interface of the universal test mainboard unit.

[0086] When the BCMS to be tested receives the simulated BCMS first test signal, the simulated BCMS second test signal or the simulated BCMS third test signal, it starts the service test. When the BCMS to be tested performs the service test, the BCMS to be tested determines whether it is necessary to simulate the BCMS second test signal.

[0087] Specifically, the BCMS to be tested determines whether it needs to request the simulation device to send some signals based on the received signal and protocol content, and reports it to the universal test mainboard if necessary, which then reports it to the host computer.

[0088] If it is necessary to simulate the second BCMS test signal, the BCMS to be tested sends a request signal to the universal test mainboard unit. After the BMS to be tested completes the service test based on the simulated BCMS first test signal, the simulated BCMS second test signal, and the simulated BCMS third test signal, the BCMS to be tested reports the BCMS test result to the host computer. If it is not necessary to simulate the second BCMS test signal, after the BMS to be tested completes the service test based on the simulated BCMS first test signal and the simulated BCMS third test signal, the universal test mainboard unit receives the BCMS test result and uploads it to the host computer. Finally, the host computer outputs the corresponding test report based on the BCMS test results reported by the BCMS to be tested and the BCMS test results uploaded by the universal test mainboard unit, completing the entire BCMS auxiliary test process.

[0089] In this process, if the BCMS to be tested does not receive the simulated BCMS first test signal or the simulated BCMS second test signal or the simulated BCMS third test signal, and the host computer does not receive the BCMS test result within the set time, it means that this test has failed, and the host computer outputs a corresponding test failure report, indicating that this test has failed, and the host computer outputs a corresponding test failure report, indicating that the BCMS communication protocol simulation test has failed; if the host computer receives the BCMS test result within the set time, the test continues. Preferably, the set time can be 3 seconds.

[0090] EMMU-assisted testing method:

[0091] like Figure 4 As shown, the simulated BMS test signal includes: a simulated EMMU first test signal, a simulated EMMU second test signal, and a simulated EMMU third test signal; the host computer simulates the communication protocol and communication interface of the actual device.

[0092] The host computer sets the automatic trigger conditions in advance, and selects the corresponding simulated EMMU first test signal, simulated EMMU second test signal, and simulated EMMU third test signal according to the EMMU to be tested; if the automatic trigger conditions are met, the host computer sends the simulated EMMU first test signal to the universal test mainboard unit; if the automatic trigger conditions are not met, the host computer judges the return signal of the universal test mainboard.

[0093] If the return signal is the request signal of the EMMU to be tested, the host computer sends the simulated EMMU second test signal to the universal test mainboard unit; if the return signal is not the request signal of the EMMU to be tested, the host computer sends the simulated EMMU third test signal to the universal test mainboard unit.

[0094] Subsequently, determine whether the test motherboard unit needs to output the simulated EMMU first test signal, the simulated EMMU second test signal, and the simulated EMMU third test signal; if the test motherboard unit needs to output the simulated EMMU first test signal, the simulated EMMU second test signal, and the simulated EMMU third test signal, the universal test motherboard unit outputs the simulated BCMS first test signal, the simulated EMMU second test signal, and the simulated EMMU third test signal according to the instruction, and sends the simulated EMMU first test signal, the simulated EMMU second test signal, and the simulated EMMU third test signal to the EMMU to be tested through the RS485 / RS232 interface of the universal test motherboard unit; if the universal motherboard test unit does not need to output the simulated EMMU first test signal, the simulated EMMU second test signal, and the simulated EMMU third test signal, then the simulated EMMU first test signal, the simulated EMMU second test signal, and the simulated EMMU third test signal are forwarded to the EMMU to be tested through the RS485 / RS232 interface of the universal test motherboard unit.

[0095] When the EMMU to be tested receives the simulated EMMU first test signal, the simulated EMMU second test signal or the simulated EMMU third test signal, the service test is started. When the EMMU to be tested performs the service test, the EMMU to be tested determines whether the simulated EMMU second test signal is needed.

[0096] Specifically, the EMMU to be tested determines whether it needs to request the simulated device to send some signals based on the received signal and protocol content, and reports it to the universal test mainboard if necessary, and the test mainboard reports it to the host computer.

[0097] If it is necessary to simulate the second test signal of EMMU, the EMMU to be tested sends a request signal to the universal test mainboard unit. After the service test of the EMMU to be tested is completed according to the simulated first test signal of EMMU, the simulated second test signal of EMMU and the simulated third test signal of EMMU, the EMMU to be tested reports the EMMU test result to the host computer; if it is not necessary to simulate the second test signal of EMMU, after the service test of the EMMU to be tested is completed according to the simulated first test signal of EMMU and the simulated third test signal of EMMU, the universal test mainboard unit receives the EMMU test result and uploads it to the host computer. Finally, the host computer outputs the corresponding test report according to the EMMU test result reported by the EMMU to be tested and the EMMU test result uploaded by the universal test mainboard unit, completing the entire EMMU auxiliary test process.

[0098] In this process, if the EMMU to be tested does not receive the simulated EMMU first test signal, the simulated EMMU second test signal, or the simulated EMMU third test signal, and the host computer does not receive the EMMU test result within the set time, it means that the test has failed, and the host computer outputs a corresponding test failure report, indicating that the EMMU communication protocol simulation test has failed; if the host computer receives the EMMU test result within the set time, the test continues. Preferably, the set time can be 3 seconds.
