[0036] As a specific embodiment of the utility model:

[0037] Take the detection of the accelerator pedal as an example: the detection personnel connect the first conductive clip 101 to the No. 1 line of the 5V accelerator pedal, connect the second conductive clip 102 to the No. 2 line, and connect the third conductive clip 103 to the No. 3 line. The detection personnel can wake up the detection device by saying the wake-up word "Is Xiaochi here?". When the wake-up is successful, the speaker 6 of the detection device will make a voice reply "Yes, what do you want to detect today?"; the detection personnel say the command word "detect the five-volt accelerator pedal", at this time, the IO1 of the voice module 4 will execute a high-level output according to the program and will make a voice reply through the speaker 6 "detection of the five-volt accelerator pedal is ready"; when the high level is transmitted to the IN1 port of the three-way relay module 5, the K1 relay will act, COM1 and NO1 are connected, and NC1 is disconnected. At this time, the first conductive clip 101 has a 5V voltage, completing the purpose of powering the accelerator pedal. Then the inspector steps on the accelerator pedal. According to the output characteristic curve of the accelerator pedal, the greater the stepping angle, the greater the voltage. Therefore, the inspector can judge the function of the accelerator pedal by observing the changes in the pointer of the DC voltmeter 7 in the detection device. Next, the inspector will continue to test another 12V accelerator pedal. The inspector issues the command word "Xiao Chi, please standby". At this time, the voice module 4 will set all IO ports to a low level and send a voice reply "Standby" through the speaker 6. The inspector connects the first conductive clip 101 to line 1 of the 12V accelerator pedal, connects the second conductive clip 102 to line 2, and connects the third conductive clip 103 to line 3. The inspector says the command word "detect the 12-volt accelerator pedal". At this time, IO2 of the voice module 4 will execute a high-level output according to the program and will send a voice reply "detect the 12-volt accelerator pedal and it is ready" through the speaker 6; when the high level is transmitted to the IN2 port of the three-way relay module 5, the K2 relay will be activated, COM2 is connected to NO2 and disconnected from NC2. At this time, the first conductive clip 101 has a 12V voltage, completing the purpose of powering the accelerator pedal. Then the inspector steps on the accelerator pedal. According to the signal output diagram of the accelerator pedal, the greater the pedaling angle, the greater the voltage. Therefore, the inspector can judge the quality of the accelerator pedal control signal function by observing the changes in the DC voltmeter pointer 7 in the detection device. At this time, the inspector also needs to judge the switch signal. The inspector only needs to connect the third conductive clip 103 to line 4. According to the signal output diagram of the accelerator pedal, the switch signal will be 12V when the pedaling angle is greater than or equal to 2°. Therefore, the inspector steps on the accelerator pedal and observes whether the pointer of the DC voltmeter 7 in the detection device falls near 12. When the accelerator pedal is released, the pointer of the DC voltmeter 7 returns to near 0 to judge the quality of the switch signal function.

[0038] If the inspector needs to inspect the travel switch, the inspector connects the first conductive clip 101 to line 1 of the travel switch, and the third conductive clip 103 to line 2 of the travel switch. The inspector says the command word "detect the travel switch". At this time, IO3 of the voice module 4 will execute a high-level output according to the program and will send a voice reply "detection of travel switch is ready" through the speaker 6; when the high level is transmitted to the IN3 port of the three-way relay module 5, the K3 relay will act, COM3 and NO3 are connected and disconnected from NC3. At this time, the first conductive clip 101 has a voltage of 24V. At this time, the inspector pushes the push rod of the travel switch and observes whether the pointer of the DC voltmeter 7 in the detection device falls near 24. Release the push rod, and the pointer of the DC voltmeter 7 returns to near 0 to judge whether the travel switch is good or bad.

[0039] If different devices need to be tested, command words corresponding to different devices can be added to the program. In this way, only one testing device manager is needed to familiarize himself with the principles of the tested device and flash the program, and other testing personnel only need to understand the command words and wiring methods corresponding to the tested device.

[0040] It is further worthwhile to explain in detail that a sound hole 15 is provided on the side of the shell 14 , and a plurality of sound holes 15 are provided and the plurality of sound holes 15 are equidistantly distributed, and the receiving end of the voice module 4 is located on one side of the sound hole 15 .

[0041] In summary: The principle of the utility model is to use the user's command statement as the input of the voice module. The voice module controls its high and low level output through the IO port corresponding to the logical judgment input. The output is connected to the IN point of the relay module to control the corresponding relay action; different relay actions can make the first conductive clamp carry different voltages to match the voltage of the detected device; the third conductive clamp is connected to the signal output line of the detected device, and the analog voltage is transmitted to the 85C1 DC voltmeter, so that it can be observed in real time whether the detected device outputs normal analog voltage, so as to know whether the function of the detected device is normal; the utility model is specifically aimed at the voltage platform of the low-voltage equipment of the vehicle, and adopts a programmable voice control module to solve the problems of the existing detection method, which is not universal and inconvenient. The purpose is to enable the detection personnel to conduct the detection of low-voltage equipment more simply and conveniently, and improve the efficiency of product warehousing detection.
