[0021] Next, in combination with the accompanying drawings in the embodiments of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described.

It is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation to the present invention. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances. Multiple technical solutions in the same embodiment, as well as multiple technical solutions in different embodiments, can be combined to form new technical solutions without contradiction or conflict, and all are within the scope of protection required by the present invention.

[0022] Referring to Figure 1 , a schematic structural diagram of a device for testing a device provided by an embodiment of the present invention. Among them, the device 10 for testing a device includes: a bus development environment device 110 and a programmable power supply 120;

[0023] The bus development environment device 110 has a test control signal input end 111, a test message output end 113, and a power control signal output end 112;

[0024] The programmable power supply 120 has a power control signal input end 121 and a power output end 122;

[0025] The test control signal input end 111 is connected to the test control signal output end 201 of the computer 20;

[0026] The test message output end 113 is connected to the test message input end 301 of the device under test 30;

[0027] The power control signal output end 112 is connected to the power control signal input end 121, and the power output end 122 is connected to the power input end 302 of the device under test 30.

[0028] Among them, the bus in the bus development environment device is a communication bus. The communication bus is a shared line used to connect different devices or systems and realize information transmission between the connected devices or systems. Based on this, the bus development environment device provides a communication network for the connected computer, device under test, and programmable power supply to realize the control of the device under test and the programmable power supply.

[0029] It can be understood that the test control signal input terminal 111 of the bus development environment device 110 is connected to the test control signal output terminal 201 of the computer 20. The tester can program on the bus development environment software installed on the computer 20 to obtain a test message for testing the device under test, as well as a power control signal or a power control message for controlling the programmed power supply to output a preset power supply. Further, when the user determines the output message on the computer 20, the test message and the power control signal are transmitted to the connected bus development environment device 110 through the test control signal output terminal 201 of the computer 20, facilitating the bus development environment device 110 to control the programmed power supply and test the device under test.

[0030] The programmed power supply 120 is a power supply device with programming functions, and can control the maximum current, maximum voltage, maximum power, actual voltage, actual current, constant current / constant voltage and other power supply modes output through computer software programming.

[0031] In the embodiment of the present application, the programmed power supply 120 receives the power control signal or the power control message output from the power control signal output terminal 112 of the bus development environment device 110 through the power control signal input terminal 121. Based on its own programming analysis ability, the programmed power supply 120 analyzes the power control signal and adjusts the power supply parameters, such as the voltage amount, current amount, output frequency, etc. of the power supply, so that the output power supply is the power supply required by the power control signal. Through the connection between the power output terminal 122 of the programmed power supply 120 and the power input terminal 302 of the device under test 30, the programmed power supply 120 provides power to the device under test.

[0032] After receiving the electric energy input through the power input terminal 302, the device under test 30 can operate normally. Further, according to the test message received by the test message input terminal 301, the operation state of the device under test is adjusted according to the test strategy of the test message, so that the device under test is in a test state.

[0033] In summary, in the device for testing a device provided in the embodiment of the present application, the bus development environment device receives a test message and a power control signal through the test control signal input terminal. After the device under test is connected to the bus development environment device, the test process can be started according to the received test message; at the same time, through the connection between the power control signal input terminal of the programmed power supply and the bus development environment device, the programmed power supply can provide corresponding electric energy to the device under test according to the received power control signal. In this process, there is no need for the user to manually replace the power supply or debug the power supply parameters. Based on this, the embodiment of the present application improves the automation and test efficiency of device testing.

[0034] Further, other possible implementations of the device for testing a device provided in the embodiment of the present application are described.

[0035] In a possible implementation, the bus development environment device includes: a Controller Area Network (CAN) bus development environment device.

[0036] Among them, the Controller Area Network open environment (CANOE) device is a bus development environment for the automotive electronics industry, mainly used for communication in automobiles and some other embedded systems, and is designed to achieve real-time communication in fields such as automotive electronic control systems and industrial automation systems. The CAN communication interface on the CANOE device can communicate with various parts of the vehicle, such as the engine control system and braking system, to achieve control or testing of various parts of the vehicle.

[0037] For example, when the device under test is a vehicle headlight bench, CAN communication can be achieved between the CANOE device and the roof bench to control the headlight bench to be in a test state, and the programmable power supply can be controlled through the power control signal output port of the CANOE device to output corresponding electrical energy to the headlight bench.

[0038] In a possible implementation, the power control signal input terminal of the programmable power supply includes: a serial communication interface.

[0039] There are usually multiple interfaces for connection on the programmable power supply for power supply, information transmission, etc. Among them, the COM interface for control of the programmable power supply can be used as the power control signal input terminal. The COM interface can control the electrical energy output by the programmable power supply using the received power control signal... The COM interface, that is, the serial communication interface, can also be called a serial port or serial communication interface, which is an extended interface using serial communication. Its characteristic is that the communication line is simple, and two-way communication can be achieved with only a pair of transmission lines.

[0040] Therefore, in the embodiments of the present application, the COM interface of the programmable power supply can be connected to the power control signal output terminal of the CANOE device using a data cable or transmission line with a COM connector. Among them, the power control signal output terminal of the CANOE device can include a db9 interface. The db9 interface is a 9-pin RS-232 interface, that is, a nine-pin serial port, which is another form of serial communication interface. Based on this, two-way communication between the programmable power supply and the bus development environment device can be achieved. Although in the embodiments of the present application, the bus development environment device unidirectionally transmits the power control signal to the programmable power supply, in a possible implementation, the programmable power supply can feedback the control situation of the power control signal to the bus development environment device through two-way communication, facilitating the tester to discover power problems as early as possible and improving the controllability of power control.

[0041] In a possible implementation, the test control signal input terminal of the bus development environment device includes a USB interface, and the test control signal output terminal of the computer is connected to the USB interface of the bus development environment device through a USB data cable.

[0042] It can be understood that the bus development environment device needs to be connected to the computer to visualize the messages or programs running in the bus development environment device, facilitating the tester to edit them. In the embodiments of the present application, the bus development environment device has a USB interface and is connected to the test control signal output terminal of the computer through a USB data cable, enabling the computer to transmit the messages or signals edited by the tester on the computer to the bus development environment device.

[0043] In a possible implementation, the test control signal input terminal of the bus development environment device includes a wireless communication module, and the computer is connected to the test control signal input terminal of the bus development environment device by connecting to the wireless network provided by the wireless communication module.

[0044] Among them, the wireless communication module may include: a Bluetooth module, a wifi module, a ZigBee module, etc. When the bus development environment device supports wireless communication, the computer listens to the signal frames sent by the surrounding wireless communication modules, searches for the surrounding wireless networks, and after collecting the network signal output by the wireless communication module of the bus development environment device, connects to it to input the test control signal into the bus development environment device in the case of wireless communication.

[0045] In a possible implementation, the test signal output terminal of the device under test is connected to the test result acquisition terminal of the computer.

[0046] It can be understood that the purpose of testing the device under test is to collect the test data of the device under test, analyze the test data, and optimize its performance according to the analysis results. Therefore, in the embodiments of the present application, all the test data generated by the device under test during the test process can be output through the test signal output terminal, and the test signal output terminal is connected to the test result acquisition terminal of the computer. The computer receives all the test data, and then the computer can perform data analysis and processing on the received test data. The result of the data analysis and processing can be used as the basis for subsequent optimization of the device under test.

[0047] It can be understood that the hardware port designs of devices such as bus development environment devices and programmable power supplies of different brands and models are different. In actual applications, the connection methods between the bus development environment device, the device under test, the computer, and the programmable power supply can be determined according to various factors such as the functions and matching degrees of each port. The above embodiments are a possible implementation connection method, not the only limited implementation method.

[0048] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not used to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some of the technical features.
