[0038] In this embodiment, the lifting rod 151 is made of aluminum alloy and has through holes (not shown) on it. The spacing of the through holes is 5 mm.

[0042] In one embodiment of the utility model, the rotating motor 122 and / or the lifting motor 152 is a turbine-reduced self-locking DC motor, which is not easy to generate vibration and noise, and has a power-off self-locking function. When setting the card reading distance in the test, the card reading distance is guaranteed to be stable.

[0043] Furthermore, the reliability testing device further includes a card reading times recording component 17, which is disposed in the housing 11 and electrically connected to the control mechanism 16, and records the card reading times of the card reader.

[0044] Among them, the card reading times recording component 17 includes: a rotating arm 171 and a first opposing photoelectric sensor 172; the rotating arm 171 is installed on the output shaft of the rotating motor 122, and the rotating arm 171 rotates synchronously with the radio frequency card clamping mechanism 13; the first opposing photoelectric sensor 172 is installed on the inner wall of the shell 11 and is electrically connected to the control mechanism 16, and the card reading times are recorded by blocking the transmission and reception of the first opposing photoelectric sensor 172 when the rotating arm 171 rotates.

[0046] In this embodiment, the rotating arm 171 is made of aluminum alloy, and its installation direction is parallel to the RFID card clamping mechanism 13 . The detection of the number of card readings is achieved by cooperating with a beam-type photoelectric sensor.

[0047] Furthermore, the control mechanism 16 includes: a control board 161 and a control terminal 162, the control board 161 is arranged at the bottom of the shell 11 and is electrically connected to the rotating mechanism 12, the lifting mechanism 15 and the card reading number recording component 17; the control terminal 162 is electrically connected to the control board 161 and the card reader 3, the control command output by the control terminal 162 is output to the rotating mechanism 12 and the lifting mechanism 15 through the control board 161, the control terminal 162 receives the radio frequency card data, and the control terminal 162 receives the output signals of the first opposing photoelectric sensor 172 and the second opposing photoelectric sensor 153 through the control board 161.

[0048] In this embodiment, the control board adopts a 32-bit ARM microcontroller solution, and controls the entire device through control instructions output by the control terminal 162.

[0051] Please refer to the following Figure 1 , combined with Figure 1 The working process of the utility model is described as follows:

[0052] When testing, clamp four radio frequency cards 2 for testing at the radio frequency card clamping position P1, clamp the card reader 3 to be tested for reliability at the card reader clamping position P2, enter the data of the four radio frequency cards 2 at the control terminal 162, and set the card reading distance and the number of tests to be tested. Multiple card reading distances can be set, and the distance interval is at least 5mm. Tests of different card reading distances can be completed at one time. After the settings are completed, start the test;

[0053] When the test starts, the reliability test device will reset the card reading distance to zero through the long arm micro switch 18 and the second photoelectric sensor 153 each time it is turned on. The control terminal 162 outputs a control command to the control board 161. The control board 161 first controls the lifting motor 152 to drive the lifting rod 151 to run through the gear, and the second photoelectric sensor 153 detects the through hole of the lifting rod 151 to adjust the card reading distance. After adjusting to the first test distance to be set, the control board 161 controls the lifting motor 152 to cut off the power, and the turbine deceleration self-locking DC motor is self-locked, completing the setting of the card reading distance.

[0054] After completing the card reading distance setting, the control board 161 controls the rotating motor 122 to rotate, and the rotating arm 171 continuously blocks the transmission and reception of the first opposing photoelectric sensor 172 during rotation to record the number of tests. Each time the rotating arm 171 blocks the opposing photoelectric sensor, the test radio frequency card 2 is just above the card reader 3 and stays for a preset time. In this embodiment, the preset time is 1 second. The radio frequency card data read by the card reader 3 is uploaded to the control terminal 162 for comparison with the test card data entered in advance and the read data and results are displayed. After completing the test of this card reading distance, the control board 161 controls to automatically perform the test of the card reading distance set later. After all tests are completed, the pressure test device automatically resets the card reading distance to zero, and the reliability test software displays the final test results.

[0055] To summarize, by sending control instructions to the control board, the control board controls the turbine-reduced self-locking DC motor at the bottom to drive the lifting arm through gears, and the card reading distance is adjusted by detecting the through holes on the lifting arm through the through-beam photoelectric sensor, thereby automatically realizing reliability testing at multiple card reading distances. Based on this, compared with the existing automated testing devices, this test device is more compatible with different card readers, avoiding the problem of manually adjusting the test device when testing different card reading distances during the test, thereby improving the test efficiency.
