[0054] Embodiment 1

[0055] This embodiment provides a transponder tester, which can conveniently and quickly complete the test of the transponder outdoors and determine whether the transponder is currently in a qualified state.

[0056] Specifically, see Figure 1-Figure 4In this embodiment, the transponder tester includes a box 1 and a transponder test module 2.

[0057] The box body 1 includes a base 11 and a box cover 12. A receiving cavity with an opening is provided in the base 11. The box cover 12 is hinged to the base 11 and can open or close the opening of the receiving cavity.

[0058] The transponder test module 2 is arranged in the accommodating cavity, and the transponder test module 2 includes a display panel 21, a control unit 22 and an inductor unit 23. The inductor unit 23 can sense the antenna of the transponder, and the inductor unit 23 is communicatively connected with the control unit 22. The control unit 22 can process the received signal and display the processing result on the display panel 21.

[0059] It should be noted that the technology of processing the received signal by the control unit 22 belongs to the prior art and will not be introduced in detail here.

[0060] The transponder tester provided in this embodiment is convenient to carry outdoors to test the transponder to be tested because it is provided with a box 1. When testing whether the transponder is qualified or not, open the box cover 12, put the transponder tester on the designated position of the antenna of the transponder to be tested, the inductor unit 23 senses and resonates with the antenna of the transponder, and the inductor unit 23 is connected to the control unit 22 for communication. The control unit 22 can process the received signal and display the processing result on the display panel 21. The tester can judge whether the transponder to be tested is qualified by observing the display result of the display panel 21.

[0061] Specifically, if the processing result displayed by the display panel 21 meets the set requirements, the transponder under test is determined to be qualified; otherwise, the transponder under test is determined to be unqualified.

[0062] Among them, see Figure 5-Figure 7 The inductor unit 23 includes an inductor 231 and an inductor support 232 .

[0063] The inductor 231 can sense and resonate with the antenna of the transponder. When the inductor 231 resonates, the current flowing through the inductor 231 will change, and whether the transponder is qualified or not can be determined based on the current value.

[0064] The inductor support 232 is disposed in the accommodating cavity, and the inductor 231 is installed on the inductor support 232 .

[0065] Furthermore, the inductor unit 23 further includes a shielding cover 233, which is disposed in the accommodating cavity. The shielding cover 233 is provided with an accommodating cavity with an opening toward the bottom plate of the base 11, and the shielding cover 233 and the bottom plate are jointly enclosed to form a shielding cavity, and the inductor 231 and the inductor support 232 are both disposed in the shielding cavity, and the inductor 231 is disposed in contact with the bottom plate.

[0066] The shielding cover 233 can prevent external signals from interfering with the operation of the inductor 231, thereby ensuring the accuracy of the test results of the transponder tester.

[0067] Specifically, see Figure 6 and Figure 7 In this embodiment, the inductor coil support 232 includes an inductor coil support body 2321 and an inductor coil clamp 2322 .

[0068] Along the first direction, an inductor clamping claw 2322 is respectively disposed at two ends of the inductor support body 2321 , and the inductor 231 is clamped between the two oppositely disposed inductor clamping claws 2322 .

[0069] Such an arrangement can ensure the stability of the installation of the inductor coil 231, thereby ensuring the accuracy of the test result of the transponder tester.

[0070] More specifically, along the second direction, an inductor clamping claw 2322 is respectively provided at both ends of the inductor support body 2321, and the four inductor clamping claws 2322 and the inductor support body 2321 together form an inductor clamping space, and the inductor 231 is clamped in the inductor clamping space.

[0071] Specifically, in this embodiment, the first direction and the second direction are perpendicular to each other, wherein one of the first direction and the second direction is the length direction of the inductor support body 2321 , and the other is the width direction of the inductor support body 2321 .

[0072] Furthermore, abutment posts 23211 are provided on the surface of the inductor support body 2321 facing the top plate of the shielding cover 233 , and the upper ends of the abutment posts 23211 abut against the lower surface of the top plate of the shielding cover 233 , thereby ensuring the accuracy and stability of the installation position of the inductor support 232 .

[0073] Further, see Figure 4 and Figure 8 The control unit 22 includes a control board 221, and the control board 221 can measure antennas of different frequencies. For example, the control board 221 can measure antennas of frequencies of 500 Hz, 1000 Hz, and 2000 Hz.

[0074] Further, see Fig. 9 and Fig.10 , the control unit 22 also includes a control board mounting member 222 and a battery.

[0075] The control board mounting member 222 is disposed in the accommodating cavity, the inductor unit 23 is sandwiched between the bottom plate of the base 11 and the control board mounting member 222 , and the control board 221 is mounted on the control board mounting member 222 .

[0076] The battery is disposed on the control board mounting member 222 to supply power to the control board 221 .

[0077] Furthermore, a battery accommodating box 2221 is provided on the control board mounting member 222 , and the battery is arranged in the battery accommodating box 2221 .

[0078] Specifically, the battery storage box 2221 includes a box body and a box cover, the box body is integrally formed and arranged on the control board mounting member 222, a battery storage cavity with an upward opening is arranged in the box body, and the box cover can be buckled at the upper end opening of the battery storage cavity to protect the battery. Furthermore, a wire threading groove is opened on the side wall of the box body, and the wires and signal wires connected to the battery are connected to the battery in the box body through the wire threading groove.

[0079] Specifically, in this embodiment, the battery is a storage battery. The storage battery can be charged, so that the transponder tester can be directly carried outdoors for operation.

[0080] Furthermore, a display panel support column 2222 is provided on the control panel mounting member 222, and the display panel 21 is fixedly provided on the display panel support column 2222. Specifically, the display panel 21 is fixedly provided on the free end of the display panel support column 2222.

[0081] A plurality of working modules are integrated on the control board 221 , and the arrangement of the display panel support column 2222 can avoid interference between the display panel 21 and the working modules on the control board 221 .

[0082] Specifically, in this embodiment, see Figure 3 The display panel 21 is provided with a display element 211, a signal indicator light 212, a signal selection switch 213, an AC220V interface 214 and a power switch 215. The display element 211, the signal indicator light 212, the signal selection switch 213, the AC220V interface 214 and the power switch 215 are all electrically connected to the control unit 22.

[0083] The display element 211 is a display screen. The display screen can display current. Specifically, the current unit displayed on the display screen is mA.

[0084] The power switch 215 has an LED indicator light. When the power switch 215 is pressed, the LED indicator light turns on and the transponder tester starts to work. The AC220V interface 214 is a power supply interface of the transponder tester and also a charging interface of the battery.

[0085] The signal indicator light 212 is specifically a frequency indicator light.

[0086] The control unit 22 includes a light position switching component, a power management component, a signal generating component, and a signal switching component.

[0087] The signal selection switch 213 is electrically connected to the light position switching component, the signal generating component and the signal switching component. The AC220V interface 214 and the power switch 215 are electrically connected to the power management component.

[0088] Specifically, the signal selection switch 213 can be operated to select different frequencies; after the frequency is selected, the indicator light of the corresponding frequency lights up. Further specifically, in this embodiment, the signal selection switch 213 is a rotary switch passing through the display panel 21. The rotary switch has four gears; zero gear is normal without test function; first gear is 500Hz frequency; second gear is 1000Hz frequency; third gear is 2000Hz frequency.

[0089] Specifically, see Fig.11 In this embodiment, the transponder tester is placed at the designated position of the antenna of the transponder under test, and the inductor 231 is induced and resonated with the antenna of the transponder under test. The inductor 231 resonates, and the current generated by the inductor 231 is processed by the control unit 22 and displayed on the display element 211 on the display panel 21. The tester determines whether the transponder under test is in a qualified state by observing the current value on the display element 211.

[0090] If the current value displayed on the display element 211 is less than the set value, the transponder under test is determined to be qualified; otherwise, the transponder under test is determined to be unqualified.

[0091] Optionally, the set value is 147 mA. Optionally, in other embodiments, the set value may be 140 mA, 141 mA, 142 mA, 143 mA, 144 mA, 145 mA or 146 mA.

[0092] Specifically, in this embodiment, the working power supply indicator of the transponder tester is AC220V or the battery of the transponder tester; wherein, the charging voltage of the battery is 12.6V and the discharge voltage is +12VDC. The detection frequencies of the transponder tester include 500Hz±1%, 1KHz±1% and 2KHz±1%. The current value displayed on the display element 211 ranges from 0mA to 500mA. The measurement accuracy of the transponder tester is 1mA. The current when the transponder tester does not generate resonance is 270±5mA. The current when the transponder tester resonates with the antenna of the transponder under test is less than 140mA.

[0093] Specifically, see Fig.11 The control board 221 of the transponder tester provided in this embodiment includes a signal generating unit with three frequencies, which are 500Hz, 1KHz and 2KHz respectively, with an accuracy of ±1%. The signal generating unit uses the square wave signal generated by the counter to form a sine wave after filtering, and then connects to the class D power amplifier through a voltage follower, and then connects to the primary side of the isolation transformer through an LC low-pass filter circuit after the power amplifier output, and outputs the three frequency signals through the transformer isolation.

[0094] The signal generating unit forms resonance with the RC oscillation circuit and the inductor 231 through the selection of the signal switching unit. The current generated by the resonance reflects the quality of the external antenna under test. The current is displayed on the display element 211 of the display panel 21 through the current detection unit to guide the staff's work.

[0095] The inductor 231 is made of a special magnetic core and winding process. In order to avoid magnetic induction with the circuit on the control board 221, a shielding cover 233 is added between the inductor 231 and the control board 221 so that the inductor 231 and the antenna under test can accurately form resonance.

[0096] The transponder tester also includes a power management component, which can realize free switching between external AC220V and battery power supply, and can also use AC220V input power to charge the battery; adding a battery power supply mode facilitates outdoor portable operations.

[0097] The signal selection switch 213 of the display panel 21 simultaneously switches the signal switching unit and the light position switching unit of the control board 221 , so that the signal output by the signal generating unit is consistent with the desired frequency signal, and the corresponding signal indicator light 212 can be lit at the same time.

[0098] Optionally, in this embodiment, the length, width and height of the box body 1 are 325 mm, 211 mm and 135 mm, respectively. Optionally, in this embodiment, the length and width of the display panel 21 are 321 mm and 207 mm, respectively.

[0099] Of course, in other embodiments, the size of the box body 1 can be set as required, and no excessive restrictions are made here.

[0100] Embodiment 2

[0101] Specifically, see Fig.12 This embodiment provides a transponder testing method, which uses the transponder tester of the first embodiment to test the transponder under test, including the following steps:

[0103] S2. Place the transponder tester at the designated position of the antenna of the transponder under test;

[0104] S3. Determine whether the processing result displayed on the display panel 21 meets the set requirements; if yes, determine that the transponder under test is qualified; if not, determine that the transponder under test is unqualified.

[0105] The transponder testing method provided in this embodiment uses the transponder tester provided in the first embodiment to test the transponder under test, so that the test of the transponder can be completed quickly outdoors to quickly detect whether the transponder under test is qualified.

[0106] Specifically, in this embodiment, the setting requirement is that the current value displayed by the display panel 21 is less than the set value. Optionally, the set value is 147mA. Optionally, in other embodiments, the set value may be 140mA, 141mA, 142mA, 143mA, 144mA, 145mA or 146mA.

[0107] Furthermore, the following steps need to be performed between step S1 and step S2:

[0108] S01, determine whether the transponder tester needs to be powered by an external AC220V power supply; if yes, connect the AC220V power supply; if no, use a battery for power supply;

[0109] S02, pressing the power switch 215 of the transponder tester;

[0110] S03, determine whether the LED of the power switch 215 is on, and determine whether the display element 211 displays 0.000; if both are yes, execute step S04; if any one of the results is no, test the transponder tester;

[0111] S04, select the signal selection switch 213 to the frequency position corresponding to the antenna frequency of the transponder under test;

[0112] S05. Determine whether the signal indicator light 212 of the corresponding frequency gear is on, and determine whether the value displayed by the display element 211 is between 270mA and 280mA; if both are yes, execute step S2; if any one of the results is no, test the transponder tester.

[0113] Specifically, in the above operation, the transponder tester is tested by corresponding technicians.

[0114] Specifically, in step S01, if the power of the battery of the transponder tester is insufficient to support the normal operation of the transponder tester, an external AC220V power supply is required.

[0115] Specifically, in this embodiment, after step S2 is completed, the following operations need to be performed: switching the signal selection switch 213 to the zero position, and closing the signal selection switch 213 .
