[0035] Here, the exemplary embodiments will be described in detail, and the examples are shown in the drawings. When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The implementation manners described in the following exemplary embodiments do not represent all the implementation manners consistent with the present disclosure.
[0036] The SAR sensor can accurately detect the proximity of a human body and accordingly control the radio frequency (RF) transmission power, so as to meet the SAR standards in smart terminals and wearable devices. Among them, SAR is the ratio of the energy absorbed by a human body when exposed to an electromagnetic field. Relevant regulatory agencies require the device to limit the radio frequency energy absorbed by the human body by reducing its transmission power when it is close to the human body. The proximity sensor based on capacitive sensing technology detects the approach of a human body and reduces the radio frequency power when needed.
[0037] In the related art, there is a method for reducing SAR. The proximity sensor based on capacitive sensing technology in the method for reducing SAR can be used to detect the approach of a human body. Currently, some terminals are equipped with SAR sensors. Since the human body is an electrical conductor, when the human body comes into contact with the terminal or the terminal approaches the face, the SAR sensor can detect the change in capacitance value and feedback it to the terminal processor. After receiving the detection instruction, the terminal will reduce the radio frequency power to reduce the radiation value. The working principle of the SAR sensor is that the SAR sensor can detect the capacitance of the sensor to the ground. When the human body approaches the SAR sensor, the SAR sensor will discharge to the human body, thereby changing the capacitance value of the SAR sensor to the ground. Different distances between the human body and the SAR sensor result in different changes in the capacitance of the SAR sensor to the ground, and based on this, the distance between the human body and the SAR sensor is judged. In the related art, the distance between the human body and the SAR sensor cannot be accurately measured.
[0038] In view of this, the present disclosure provides a test device.
[0039] Figure 1 It is a schematic structural diagram of a measuring device shown according to an exemplary embodiment. Refer to Figure 1 As shown, the device includes the following.
[0040] In an embodiment of the present disclosure, the test device 100 includes a base 101, a robotic arm 102, and a lifting shaft 103. Among them, the base 101 is used to place an electronic device, and the SAR sensor is installed in the electronic device. The robotic arm 102 includes a metal plate for triggering the SAR sensor in the second electronic device to detect sensing data, so that the SAR sensor determines the induction distance between the robotic arm 102 and the SAR sensor based on the sensor data. Among them, the second electronic device can be the Figure 1 electronic device in. The lifting shaft 103 is used to support the robotic arm to lift to a specified position away from the second electronic device.
[0041] In an embodiment of the present disclosure, as Figure 1 shown, it further includes a pressure sensor 105. The pressure sensor 105 is placed below the base 101 and is used to detect the pressure generated when the robotic arm 102 contacts the electronic device to determine the initial distance between the robotic arm 102 and the SAR sensor. When the pressure sensor 105 contacts the electronic device, the generated pressure is the initial position determined by the robotic arm 102.
[0042] In an embodiment of the present disclosure, as Figure 1 shown, it further includes a foam block 106. The foam block 106 is arranged on the base 101, and the electronic device is placed on the foam block 106. Among them, the foam block 106 can be selected but not limited to a foam block made of a low dielectric constant material, so that the electronic device placed on the foam block 106 will not trigger the SAR sensor to avoid interference from other factors.
[0043] In the embodiments of the present disclosure, as Figure 1 shown, it further includes a limit sensor 107 and a limit sensor 108. The multiple limit sensors are used to limit the movement of the robotic arm to different distances from the SAR sensor. It can be understood that when the robotic arm 102 contacts the electronic device, the pressure generated by the pressure sensor 105 causes the robotic arm 102 to return to the position of the limit sensor 107, that is, the initial position, and the robotic arm 102 only moves between the limit sensor 107 and the limit sensor 108.
[0044] In the embodiments of the present disclosure, the electronic device equipped with the SAR sensor is placed on the base 101, and the test device 100 controls the robotic arm 102 to lift along the lifting shaft 103 to the designated position of the electronic device based on the SAR sensor distance parameter received by the control module. The designated position can be the position where the limit sensor 107 is located. It can be understood that the robotic arm 102 moves between the limit sensor 107 and the limit sensor 108. Based on the robotic arm 102 reaching the designated position, the SAR sensor in the electronic device is triggered to detect sensing data, so that the SAR sensor determines the induction distance between the robotic arm and the SAR sensor based on the sensing data. Through this device, the multi-directional movement of the robotic arm 102 can be realized, providing persuasive data support for the test of the terminal's SAR sensor in a real scenario.
[0045] Based on the same concept, the embodiments of the present disclosure provide a method for determining the induction distance of a SAR sensor. The method for determining the induction distance of the SAR sensor is applied to the test device involved in the above embodiments.

[0049] In the embodiments of the present disclosure, the first electronic device can be a computer device for testing, the second electronic device can be a terminal, a wearable device, etc. The first electronic device is connected to the test device based on a network cable, and the second electronic device is placed on the test device to facilitate the terminal SAR sensor to obtain sensing data.
[0050] In step S12, the first electronic device obtains the SAR sensor distance parameter set by the user, and sends the SAR sensor distance parameter to the test device to control the movement of the robotic arm of the test device, triggering the second electronic device to enable the SAR sensor to detect sensing data and the movement distance of the robotic arm.
[0051] In the embodiment of the present disclosure, the first electronic device obtains the distance parameter of the SAR sensor set by the user, and based on the connection between the first electronic device and the test device, sends the distance parameter of the SAR sensor obtained by the first electronic device to the test device to control the movement of the robotic arm of the test device. Since the robotic arm includes a metal plate, the SAR sensor in the second electronic device can be triggered. Therefore, based on the movement of the robotic arm, the second electronic device is triggered to enable the SAR sensor to detect sensing data and the movement distance of the robotic arm.
[0052] In the embodiment of the present disclosure, it has been verified that when the second electronic device is tilted at different angles, the set SAR sensor distance parameter still meets the requirements. Therefore, the second electronic device placed on the test device can be tilted at different angles. Moreover, the second electronic device on the test device is within the sensing area of the SAR sensor. The sensing area of the SAR sensor can be understood as the area where the antennas do not overlap, which is convenient for determining the sensing distance method of the SAR sensor.
[0053] In step S13, the first electronic device obtains the movement distance of the robotic arm and the sensing data detected by the SAR sensor of the second electronic device, and determines the sensing distance of the SAR sensor based on the movement distance of the robotic arm and the sensing data.
[0054] In the embodiment of the present disclosure, a test application is set on the second electronic device. Based on the movement of the robotic arm, the SAR sensor on the second electronic device is triggered. The test application on the second electronic device can record the movement distance of the robotic arm and the sensing distance detected by the SAR sensor, and send them to the first electronic device. The first electronic device determines the sensing distance of the SAR sensor based on the movement distance of the robotic arm and the sensing data detected by the SAR sensor.
[0055] In the embodiment of the present disclosure, based on the connection established among the first electronic device, the second electronic device, and the test device, the determination of the sensing distance of the SAR sensor is realized, improving the accuracy of determining the sensing distance of the SAR sensor.

[0057] In step S21, the first electronic device and the test device establish a connection based on the communication methods supported by each other.
[0058] In step S22, the first electronic device runs an application program for testing the sensing distance of the SAR sensor, and obtains the communication address and communication parameters input by the user on the application display interface of the application program, and establishes a connection with the first electronic device based on the communication address and the communication parameters.
[0059] In an embodiment of the present disclosure, an application program for testing the sensing distance of the SAR sensor runs on the first electronic device, and a connection is established with the first electronic device based on the communication address and communication parameters obtained by the user input on the application display interface of the application program.
[0060] In one example, the connection method between the first electronic device and the test device is as Figure 4 shown. Figure 4 FIG. is a schematic diagram of the connection of a measuring device shown according to an exemplary embodiment. The device 200 includes a first electronic device 201, a test device 202, and also includes a control module 203.
[0061] In an embodiment of the present disclosure, the first electronic device 201 is used to run a first application program, and the first application program is used to set the distance parameter of the SAR sensor. The test device 202 is used to control the movement of the device based on the distance parameter of the SAR sensor and trigger the SAR sensor. The control module 203 is used to receive the distance parameter of the SAR sensor set by the first electronic device, and control the robotic arm to lift along the lifting axis to a specified position away from the electronic device based on the distance parameter to trigger the SAR sensor.
[0062] In one example, Figure 5 FIG. is a schematic diagram of setting the address of a test device shown according to an exemplary embodiment. As Figure 5 shown, it includes a device address (Macharm Internet Protocol, MacharmIP), a device port (MacharmPort), and obtains the test device to be connected based on the set MacharmIP and MacharmPort.
[0063] In an embodiment of the present disclosure, Figure 6 FIG. is a schematic diagram of setting the address of a comprehensive tester shown according to an exemplary embodiment. As Figure 6As shown, it includes the address of the comprehensive tester (Instrument Info), the type of the comprehensive tester (CallBox Type), the connection of the comprehensive tester (CallBox Connect), the port of the comprehensive tester (CallBox Port), and the power source (Power Supply). Among them, the comprehensive tester is located within the control module and is used to control the operation of the test device. In one example, the first electronic device can be connected to a comprehensive tester with a type of CMW500, a port of COM2, a power source of 66319; GPIBO::5::INSTR, and a connection of GPIBO::21::INSTR to realize the connection between the first electronic device and the comprehensive tester of the above type. The above is only an exemplary description and does not limit the type of the comprehensive tester.
