[0036] As described in the background art, when performing aging tests on the sensor components in a urinal, most of the time, a control circuit is used to control the opening and closing of multiple sensors to achieve aging testing of multiple sensors. However, this method usually requires relatively complex control logic and control circuits, and multiple sensors are subject to significant electromagnetic interference when operating, resulting in poor control signal reception. For example, when the control circuit controls the sensor to turn off, some working sensor components have difficulty receiving the off signal, and some sensors have different control modes, resulting in reduced accuracy of the aging test, affecting the service life of the urinal and thus the user experience.

[0037] Based on this, an embodiment of the present utility model proposes an aging test device for an inductive device, which directly regulates and controls a power module, simplifies the test circuit, and improves the accuracy of the aging test.

[0038] like Figures 1 to 3 As shown, the aging test device for inductive devices provided by some embodiments of the present invention can test multiple inductive devices. The aging test device includes: a power module 100 , a control module 200 and multiple acquisition modules 300 .

[0039] The output end of the power module 100 is electrically connected to multiple inductive devices 400, and the input end of the power module 100 is electrically connected to an external AC power source. The power module 100 can receive an external input AC voltage, process the AC voltage, and output a stable driving voltage.

[0040] Each acquisition module 300 is connected to each sensing device 400 , that is, each acquisition module 300 is connected to a sensing device 400 , and one acquisition module 300 is connected to one sensing device 400 . The acquisition module 300 can acquire the pulse signal and current data output by the corresponding sensing device 400 .

[0041] The pulse signal includes: pulse voltage and pulse width.

[0042] The output end of the control module 200 is electrically connected to the input end of the power module 100 , and the input end of the control module 200 is communicatively connected to the output ends of the plurality of acquisition modules 300 . The control module 200 can regulate the power module 100 .

[0043] That is, the control module 200 can adjust the magnitude of the driving voltage and the on / off switching of the driving voltage, thereby implementing an aging test on the plurality of sensing devices 400. The control module 200 can also receive the receiving pulse signals and current data output by the plurality of acquisition modules 300.

[0044] In one embodiment, the control module 200 regulates the power module 100 and adjusts the driving voltage, thereby controlling the on / off switching of the multiple sensing devices 400 to perform an aging test on the multiple sensing devices 400. When the multiple sensing devices 400 switch from an off state to an on state, the sensing devices 400 output pulse signals, and the acquisition module 300 collects the pulse signals and current data. The multiple acquisition modules 300 transmit pulse signals and current data, which the control module 200 receives to monitor the testing process.

[0045] The present application solution controls the power module 100 through the control module 200, directly adjusting the on and off of the driving voltage, thereby simultaneously controlling the on and off of multiple sensing devices 400. This allows for aging testing of multiple sensing devices 400, simplifies the control circuit for regulating multiple sensing devices 400, and since the sensing devices 400 do not need to receive control signals, the electromagnetic interference generated by the sensing devices 400 when powered on does not affect the aging test. This simplifies the test circuit while improving the stability and reliability of the test device and the accuracy of the aging test. This reduces the likelihood of premature failure of urinals during their service life or the need to frequently replace sensing devices within the urinals, thereby providing users with a good user experience and increasing user trust.

The host computer 210 sends the aging parameters to the timing controller 220. The timing controller 220 receives the aging parameters and, based on the aging parameters, regulates the power module 100 and adjusts the driving voltage to control the opening and closing of the multiple sensing devices 400. When the multiple sensing devices 400 are switched from the power-off state to the power-on state, the sensing devices 400 output pulse signals, and the acquisition module 300 acquires the pulse signals and current current data. The multiple acquisition modules 300 send pulse signals and current data, and the host computer 210 receives the pulse signals and current data to monitor the test process until the aging test is completed.

[0060] like Figures 1 to 3 As shown, in some embodiments of the present invention, the power module 100 includes: a rectifier 110 , a voltage regulator 120 and a power supply bus 130 .

[0062] The rectifier 110 is used to convert the AC voltage input from the external AC power supply into a DC voltage and output the DC voltage. The voltage regulator 120 is used to stabilize the DC voltage and output a driving voltage. The power bus 130 supplies the driving voltage to the multiple inductive devices 400, thereby providing a regulated power supply to the multiple inductive devices 400.
