Fig. 4 is a schematic diagram of a system framework according to an exemplary embodiment, and as shown in fig. 4, the system includes a terminal device 401, a test device 100, and a device under test 301. Fig. 5 is a schematic structural diagram of a device under test, and as shown in fig. 5, a device under test 500 includes a first wireless charging receiver 501, a first charging coil 502, and a central processor 503, where the first wireless charging receiver 501 is connected to the first charging coil 502, and the central processor 503 is connected to the first wireless charging receiver 501.

In the embodiment of the disclosure, after the test equipment is determined to be powered on, the wireless charging transmitter of the test equipment can be controlled to be in a working state, and the second wireless charging receiver of the test equipment is controlled to be in a closed state. That is, after the test device is powered up, the test device operates in a transmit (Tx) mode, the enable signal (Rx 1619_en signal) is pulled high, the second wireless charging receiver (e.g., NU1619 chip) is not operating, and the device under test (e.g., handset under test) is in a receive (Rx) mode. In some embodiments, a start test control may be clicked on a terminal device (e.g., a PC) and the device under test placed on the test station of the test device, and the device under test may enter a wireless state of charge.

In an implementation, a wireless charging transmitter (e.g., NU 1020) may obtain its second electrical parameters (e.g., input voltage and current), and the device under test may transmit the first electrical parameters (e.g., output current and voltage) of the first wireless charging receiver (e.g., NU1619 chip) to the wireless charging transmitter (e.g., NU 1020) on the test device via an ASK signal. After the wireless charging transmitter receives the first electrical parameter, the first electrical parameter and the second electrical parameter can be uploaded to a terminal device (for example, a PC) through a serial port communication mode, the terminal device can calculate power of an output device to be tested based on the first electrical parameter, calculate power of an input test device based on the second electrical parameter, and determine a positive charging test result based on the power of the input test device and the power of the output device to be tested.

For example, the reverse charging instruction is sent to a wireless charging transmitter (for example, NU1020 chip) of the test device by means of serial port communication, the wireless charging transmitter sends the reverse charging instruction to a first wireless charging receiver (for example, NU1619 chip) of the device under test by means of an FSK signal, and the first wireless charging receiver sends the reverse charging instruction to a central processor (Central Processing Unit, CPU) of the device under test by means of a bus (for example, I ² C bus), so that the CPU of the device under test turns on the reverse charging function of the device under test.

After the CPU of the device under test receives the precharge command, the precharge command is sent to the first wireless charging receiver (for example, NU1619 chip) of the device under test through the bus, the first wireless charging receiver sends response information (for example, response code) for the precharge command to the wireless charging transmitter (for example, NU1020 chip) of the test device through the ASK signal, then the wireless charging transmitter turns off energy transmission, and enables the second wireless charging receiver (for example, NU1619 chip) on the test device to enter a receiving state through the pull-up enable (RX 1619_en) signal, and meanwhile, the interrupt signal is pulled up to control the wireless charging transmitter (for example, NU1020 chip) to enter a turned-off state.

When the device to be tested provides electric energy for the test device, a third electric parameter (such as current and voltage) of the second wireless charging receiver can be obtained, and the third electric parameter is sent to the terminal device in a serial port communication mode.

For example, the terminal device may acquire parameters by using a serial port communication manner and send the parameters to a wireless charging transmitter of the test device, where the wireless charging transmitter acquires, by using a bus, a current and a voltage output by the second wireless charging receiver, and uploads, by using the serial port communication manner, the current and the voltage output by the second wireless charging receiver to the terminal device, and the terminal device may determine a reverse charging test result based on the third electrical parameter.

In other embodiments, after testing of the device under test is completed, the reverse charging function of the device under test may be turned off and power continues to be provided to the device under test based on the test device. For example, after the wireless charging transmitter of the test device detects that the interrupt signal of the second wireless charging receiver becomes low, the test device may be controlled to provide power for the device under test.

The test equipment in the embodiment of the disclosure integrates the functions of forward charging and reverse charging together, can complete all the tests of the forward charging function and the reverse charging function of the equipment to be tested through the terminal equipment, and can save the test cost on the basis of simplifying the test process. The technical scheme in the disclosure can be used for production line test of equipment to be tested (for example, mobile phones), can intercept the problem of wireless charging function of the equipment to be tested, and prevents the problematic equipment to be tested from flowing out to the hands of users.
