[0043] Please refer to Figures 3 to 5 Embodiment two of the utility model discloses:
[0044] The embodiment provides a measured device carrier, as Figure 3 As shown, the measured device carrier of the embodiment comprises a carrier body (not shown), a physical connection piece (not shown), a second wireless communication module and a wireless power receiving module; the physical connection piece, the second wireless communication module and the wireless power receiving module are arranged on the carrier body; the wireless power receiving module, the second wireless communication module and the physical connection piece are sequentially electrically connected. Figure 3 Figure 3 The carrier body is used for arranging a measured device; after the measured device is arranged in place, an electric connection relationship is established between the second wireless communication module and the wireless power receiving module through the physical connection piece.
[0045] The carrier body is used for arranging a measured device; after the measured device is arranged in place, an electric connection relationship is established between the second wireless communication module and the wireless power receiving module through the physical connection piece.
[0046] The DUT carrier of the embodiment is used in cooperation with the test fixture described in Embodiment One. That is, the wireless power transmission module in the test fixture described in Embodiment One is wirelessly connected with the wireless power receiving module in the DUT carrier of the embodiment; at the same time, the first wireless communication module in the test fixture is wirelessly connected with the second wireless communication module in the DUT carrier.

Figure 5
[0048] Here, when the distance between the DUT carrier in which the DUT is arranged and the test fixture meets the distance range required by the wireless power technology, the receiving coil in the wireless power receiving module will sense the energy emitted by the wireless power transmission module of the test fixture, and transmit the sensed energy in the form of current to the resonance circuit. The resonance circuit converts the induced energy into electric energy, and then performs rectification and filtering processing through the rectifier circuit to output a stable power supply. The power supply will be output to the second wireless communication module to provide working power source for it.

That is, the second wireless communication module is the same as the first wireless communication module. For example, if the first wireless communication module is implemented by using a wireless transceiver module, the second wireless communication module is also implemented by using a wireless transceiver module; if the first wireless communication module is implemented by using a millimeter wave communication module, the second wireless communication module is also implemented by using a millimeter wave communication module.

[0051] When the distance between the DUT carrier on which the DUT is arranged and the test fixture satisfies the wireless communication distance range specified by the wireless communication protocol, and the second wireless communication module on the DUT carrier is powered, the second wireless communication module establishes a wireless connection relationship with the first wireless communication module of the test fixture. Specifically, the second receiving unit of the second wireless communication module receives the wireless signal transmitted by the first wireless communication module in the test fixture, and then transmits it to the second logic unit for decoding and conversion into a corresponding digital signal, and then transmits it to the DUT through the physical connection for processing; when the DUT needs to feed back data, the feedback data is sent to the second logic unit for encoding and modulation to convert into a wireless signal, and then emitted by the second sending unit.
[0052] The DUT carrier provided by the embodiment has wireless power supply and wireless communication functions, and can complete the test of the DUT arranged on the carrier based on wireless interaction with the test fixture having wireless power supply and wireless communication functions, thereby avoiding the problems caused by the physical connection mode, facilitating the establishment of the connection relationship, ensuring the stability of the connection, and improving the test accuracy.

[0056] The test system provided by the embodiment can perform wireless power supply and wireless communication transmission between the test fixture and the DUT carrier, and can perform the test based on wireless interaction, thereby avoiding the problems caused by the physical connection mode from the root; thereby improving the service life of the test fixture, facilitating the establishment of the connection relationship, ensuring the stability of the connection, and improving the test accuracy.
[0057] In some specific embodiments, as Figure 6As shown, the number of test fixtures and the number of DUT carriers in the wireless communication and power supply test system are both more than two; and the test host in each test fixture executes different computer programs of different test functions. That is, each test fixture corresponds to test a function, is more targeted, and the accuracy of the test result is higher.
[0058] Optionally, the wireless communication and power supply test system further comprises a mechanical arm moving device; the DUT carrier is moved to a position spaced apart from the test fixture by a preset distance through the mechanical arm moving device.
[0059] Here, corresponding to the arrangement of the above-mentioned multiple test fixtures and multiple DUT carriers, the mechanical arm moving device can also be correspondingly configured to move the DUT carrier into the wireless power supply area and the wireless communication area of the next test fixture, so that it performs the next function test based on wireless interaction with the next test fixture, and so on. Through the mechanical arm moving device, the automatic movement of the DUT carrier is realized, thereby realizing full-automatic test completion.
[0060] The test system described in the above specific embodiments has the following test process:
[0061] (1) The DUT is placed in the DUT carrier and hard connected with the DUT carrier through the physical connecting piece; the test fixture is connected with the test host in a wired manner;
[0062] (2) The mechanical arm or other device moves the DUT carrier to be close to the test fixture, such as moving to a range of 5cm far and near from the center position of the test fixture, and a center offset of 2cm; then the test fixture sends electric energy to the wireless power supply receiving module of the DUT carrier in a wireless manner through the wireless power supply sending module, realizes wireless power supply for the DUT carrier; after the DUT carrier is powered, the second wireless communication module thereof starts bidirectional handshaking with the first wireless communication module of the test fixture to establish a wireless connection (that is, the existing wired connection is replaced by wireless connection for data transmission); then, the test host can rewrite the data of the DUT based on the wireless communication link between the test fixture and the DUT carrier, and test whether the specific function item of the DUT is normal, while the state information of other DUTs can be obtained through an additional sensor; after completing the test of the current specific function item, the DUT carrier is moved to the wireless induction range of the second test fixture connected with the second test host through the mechanical arm or other device, and the second function test is performed based on the above-mentioned principle;
[0063] (3) Repeat the steps of moving, approaching, connecting and testing until all function tests are completed.
[0064] It can be understood that wireless power supply and wireless data communication are adopted between the test fixture and the device carrier to be tested in the embodiment, so that a certain tolerance is provided for the relative positions of the two (wireless power supply and wireless data transmission can be performed within a certain distance range), the requirement for the mechanical hand moving device can be reduced (only rough alignment is needed without accurate hole alignment), the connection between the test fixture and the device carrier to be tested is easier, meanwhile, since there is no physical contact point, problems such as contact damage, poor contact and deformation do not occur, so that the stability of the connection of the two is ensured.
