Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0017] Furthermore, in the description of this application, unless otherwise stated, "multiple" means two or more. "And / or" describes the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A alone, A and B simultaneously, or B alone.

[0018] Combination Figures 1 to 4 As shown, this utility model provides a live display detector, which includes: a housing 10, which has an operation surface 110, on which buttons, wiring sockets and indicator lights 140 are provided; a battery module 20, which is disposed inside the housing 10; and a control circuit board, which is disposed inside the housing 10; the control circuit board is electrically connected to the buttons, the wiring sockets, the indicator lights 140 and the battery module 20; the control circuit board includes an inverter boost module 310 and a 3.7V to 12V boost module.

[0019] Specifically, the battery module 20 is powered by a 3.7V lithium battery. The 3.7V to 12V boost module increases the 3.7V DC voltage provided by the battery module 20 to a 12V input voltage. Subsequently, the inverter boost module 310 converts the 12V input voltage into one of three AC voltages: 20V, 200V, or 350V. The wiring connector connects to a live indicator via a probe, simulating the live indicator detecting a energized high-voltage switchgear. Feedback is provided through the indicator light 140, thus enabling the detection of the live indicator. If indicator light 140 is lit, the live indicator is working normally; if indicator light 140 is off, the live indicator is not working. Furthermore, this application features an independent battery module 20, allowing for independent operation and convenient portability.

[0020] It should be noted that the circuit used in the above-mentioned 3.7V to 12V module can be a technical means commonly used by those skilled in the art, with the purpose of boosting 3.7V to 12V; and the circuit used in the inverter boost module is also a technical means commonly used by those skilled in the art, with the purpose of boosting 12V DC voltage to 20V AC voltage, 200V AC voltage or 350V AC voltage; this application is about structural improvement, not electrical system improvement.

[0021] In this embodiment, the buttons include a switch button 120 and an inductor-capacitor switching button 130, which are arranged side-by-side on the operating surface 110. The wiring ports include a 350V inductor port, a 200V inductor port, a 20V capacitor port, and a ground port 154, which are arranged side-by-side on the operating surface 110 and located below the buttons. Depending on the type of liveness detector, one of the wiring ports of the test pen (20V capacitor port, 350V inductor port, or 200V inductor port) is connected to the liveness detector, thereby enabling this application to meet the needs of testing inductive or capacitive liveness detectors.

[0022] Furthermore, the control circuit board also includes an adjustable boost module 330, the inverter boost module 310 is connected to the 20V capacitor socket and the ground socket 154, the adjustable boost module 330 is also connected to the inverter boost module 310; the inverter boost module 310 is also connected to the 350V inductor socket and the 200V inductor socket.

[0023] In practical application scenarios: When testing a capacitive live indicator, insert one end of the red probe into the 20V capacitor socket and one end of the black probe into the grounding socket 154. Connect the other end of the red probe to the secondary output terminal of the capacitive live indicator and the other end of the black probe to the power terminal of the capacitive live indicator. Then, press the switch button 120 and the inductor-capacitor switching button 130, and observe the illumination of the indicator light 140. If the indicator light 140 is lit, it means that the capacitive live indicator is working normally. If the indicator light 140 is not lit, it means that the live indicator is not working.

[0024] When testing an inductive live indicator, insert one end of the red probe into the 200V inductor socket and one end of the black probe into the grounding socket 154. Connect the other end of the red probe to the secondary output terminal of the inductive live indicator and the other end of the black probe to the power input terminal of the inductive live indicator. Then, press the switch button 120 and the inductor-capacitor switching button 130, and observe the illumination of the indicator light 140. If the indicator light 140 is lit, it means that the inductive live indicator is working normally. If the indicator light 140 is not lit, it means that the inductive live indicator is not working.

[0025] If a 350V output is required, simply insert the red probe into the 350V inductor socket as described above.

[0026] In this embodiment, the live display detector is further provided with a charging interface 155, which is electrically connected to the control circuit board and is used to charge the battery module 20.
