[0030] In application scenarios such as mobile payment, electronic ticketing, and access control, communication between devices can be achieved through Near Field Communication (NFC) technology. Devices with NFC function usually need to undergo performance testing or parameter adjustment before leaving the factory. For example, testing or adjusting parameters such as transmission rate, transmission distance, anti-interference ability, security, power consumption, and supported protocols can accurately evaluate the performance of NFC devices, and reasonable optimization of these parameters can also improve NFC performance and user experience. At this time, another device with NFC function is required to be close to the device to be tested to cooperate in completing the test.
[0031] like Figure 1 and Figure 2 As shown, this embodiment proposes an operating device 1 and a testing system for testing NFC functional devices, which are used to complete the operation of bringing a smart device 13 with NFC function close to or away from the device to be tested, thereby improving the testing efficiency and ensuring stable testing conditions.
[0032] Reference Figure 1 The test system of the NFC functional device 2 in this embodiment includes an operating device 1 for testing the NFC functional device 2 and a set of data rewriting control devices 3. The data rewriting control device 3 is used to communicate with the NFC functional device 2 through a signal line and write or change the data of the NFC communication module in the NFC functional device 2.
[0033] Among them, combined Figure 2 The above-mentioned operating device 1 may include a mounting frame 11, a mechanical arm 12, an intelligent device 13 and a control device group 14. The mounting frame 11 is provided with a mounting position for the NFC functional device 2 to be tested. For example, the NFC functional device 2 may be a circuit board with an NFC communication module. One end of the mechanical arm 12 is connected to the mounting frame 11, and it includes at least one driving device. The intelligent device 13 is configured to be driven by the driving device, and an application based on NFC communication is provided thereon. The control device group 14 is communicatively connected with each driving device, and drives the mechanical arm 12 to move based on the test task instruction, so as to move the intelligent device 13 to a position for establishing communication with the NFC functional device 2.
[0034] During the operation of the test system, the tester can issue corresponding action commands to the control device group 14 according to the test task. The control device group 14 controls the robot arm 12 to move through a preset instruction code to move the smart device 13 to a predetermined position for communication with the NFC functional device 2 to be tested.
[0035] In addition, the data rewriting control device 3 can detect the response of the NFC functional device 2 to be tested, and perform corresponding data rewriting on the NFC functional device 2 to be tested to complete the parameter setting of the NFC functional device 2 to be tested and ensure the working performance of the NFC functional device 2.
[0036] In this way, the relative position condition between the smart device 13 and the NFC functional device 2 can be maintained extremely stably, and the test efficiency of the NFC functional device 2 can be improved.

Since the swing arm 1211 of a digital servo 121 can be bent within a range of 180 degrees, the digital servo 121 can be arranged so that the swing arm 1211 can enable the smart device 13 to communicate with the NFC functional device 2 at one angle, and when the swing arm 1211 of the digital servo 121 is rotated to another angle, the purpose of disconnecting the communication between the smart device 13 and the NFC functional device 2 can be achieved.

For example, the development board 141 is connected to the serial communication interface of the computer 142, and the serial communication interface can be any one of RS-232-C, RS-422, and RS485. The computer 142 can write the control script of the robotic arm 12 on the development board 141 in Python language.
