[0048] The technical solutions in the embodiments of the present application will be described below in conjunction with the drawings in the embodiments of the present application.

[0049] Embodiment 1

[0050] Figure 1 The structure diagram of a vehicle-mounted device test system provided in an embodiment of the present application, wherein the system includes a test device, a power controller, and a simulation power supply.

[0051] The relay of the power controller is connected between the simulated power supply and the vehicle-mounted device to be tested.

[0052] The power controller is used to switch the working state of the relay based on the power controller signal sent by the test equipment to power on or off the connected vehicle equipment.

[0053] The test device is used to obtain the target serial communication port identifier, test date, test round and test time interval edited by the user through the test interface, respond to the test signal sent by the user through the test interface, and when the test date is reached, generate a power controller signal based on the test round and test time interval, and send it to the power controller through the target serial communication port.

[0054] In a specific embodiment, the test device may be a host computer / computer, the power controller may be a DAM0404D relay control board, and the analog power supply may be a vehicle-mounted power supply for testing.

[0055] In this embodiment, a test software suitable for a test device is provided, a control interface is created based on the qtpydsigner visual framework tool of Python, and hardware devices connected to the test device are dynamically captured.

[0056] Figure 2 A schematic diagram of a test interface provided in an embodiment of the present application. Figure 2 As shown, the test interface includes a serial communication port control, a test round control, a test time interval control, and a test date control. The test device can be used for:

[0057] In response to a trigger action on a serial communication port control, a list of serial communication ports is displayed.

[0058] In response to a selection operation on a serial communication port identifier in the serial communication port list, a serial communication port identifier is determined.

[0059] The serial communication port control here can be a drop-down list box. Its drop-down list will display the corresponding identifiers of all captured serial communication ports, such as com1, com2, etc. The user needs to select the serial communication port according to the actual connection situation.

[0060] After starting, the test software will monitor the connection status of the serial communication port and determine the current serial communication port list. The serial communication port list includes at least one serial communication port identifier, and the serial communication port is a serial communication port in a connected state on the test device.

[0061] In response to an input operation on a test round control, a test round is determined.

[0062] In response to an input operation on the test time interval control, a test time interval is determined.

[0063] The test round control and test time interval control here can be an input box or a drop-down list box, etc.

[0064] The user can enter the specified test rounds and test time intervals according to the test requirements. The test rounds are the number of times the vehicle-mounted device to be tested completes the entire power-on and power-off process test. The test time interval is used to indicate the time interval between powering on and powering off the vehicle power supply in each test round.

[0065] In response to a click operation on a test date control, a test date is determined.

[0066] The test date control here can be in the form of an editable calendar control, which is used to select a specific time for the test. The test date here can include units such as year, month, day, week, hour, minute, and second.

[0067] The test interface also includes a run control. After the user edits the above information, he can click the run control to start the test task. The run control here can display the word "Start" and the word "Pause" after the test starts. The user can pause the corresponding test task by clicking again.

[0068] The test interface also includes a test result display area. After each round of testing, the software will record the test time and test results, and store the test time and test results in a local file. The test results can be displayed in real time in the test result display area, and a query interface can also be provided for users to query and export historical test results.

[0069] The following takes a test task as an example to explain the steps of executing the test software. Figure 3 As shown, the test equipment is used to perform the following steps when running the test software:

[0070] S100, responding to a test signal sent by a user through a test interface.

[0071] S101. Determine whether a test condition is met according to a connection status of a target serial communication port.

[0072] S102: If not, stop the test, generate and display a prompt message.

[0073] Avoid checking whether the target serial communication port is correctly connected. If it is disconnected, a prompt message can be generated and displayed through a pop-up window.

[0074] If so, when the test date arrives, the step of generating a power controller signal based on the test rounds and test time intervals is executed, and sending the signal to the power controller through the target serial communication port so that the power controller controls the connected vehicle-mounted device to power on or off.

[0075] Specifically, each round of testing includes the following steps:

[0076] S103: Determine the current round T=n, where n is the test round edited by the user.

[0077] S104: Generate a first power controller signal and send it to the power controller through the target serial communication port, so that the power controller controls the connected vehicle-mounted device to power on and performs timing through a counter.

[0078] S105: Determine whether the time recorded by the counter is equal to the test time interval.

[0079] S106: If yes, generate a second power controller signal and send it to the power controller through the target serial communication port, so that the power controller controls the connected vehicle-mounted device to power off.

[0080] S107: Subtract 1 from the current round T, and determine whether T is 0.

[0081] S108: If yes, then determine that the test is finished. If no, then wait for the next cycle.

[0082] Further, the power controller switches the working state of its relay according to the received power controller signal, so as to power on or off the vehicle-mounted device connected thereto; and

[0083] After step S104 and after step S106, a relay feedback signal generated by the power supply controller can also be obtained to determine whether the power-on or power-off step is successfully executed based on the relay feedback signal. If not, the test is stopped, and a prompt message is generated and displayed. If yes, the next step is continued.

[0084] The relay feedback signal is used to indicate whether the relay working state is switched successfully. If it fails, a prompt message needs to be generated and displayed through a pop-up window.

[0085] By providing a software process for automated power-on and power-off testing, the automation level of vehicle-mounted equipment testing is improved, and the manual burden is reduced. It can run uninterruptedly day and night, greatly reducing the repetitive work of manual operations. Powering on and off at fixed times significantly reduces the problem of manual time control, providing convenience for testers.
