[0027] Working principle: Take the search for a spare lane machine as an example (the spare part is placed on the B3 floor, and there are 3 of them). First, you should edit the inquiry and response statements and form a program to burn into the offline voice recognition module 11, so that the offline voice recognition module 11 can identify instructions and answer corresponding statements. When someone asks about the location of the lane machine, such as asking: Where is the lane machine. The sound will be collected by the microphone module 10, and the sound signal will be converted into an electrical signal, and then processed and transmitted to the offline voice recognition module 11. The offline voice recognition module 11 will analyze and match according to the previously burned program. When the match is consistent, the corresponding voice will be played through the speaker 12: The lane machine is on the B3 floor, and there are 3 of them;

[0028] At the same time, the serial port of the offline speech recognition module 11 will output the corresponding parameters, which will then be collected and processed by the main controller module 13. The main controller module 13 will match and control the corresponding IO pins to output high and low level signals according to the collected parameter data, and then connect the relay isolation module 14 to convert the high and low level signals into switch signals, thereby controlling the wireless transmission module 15 to transmit wireless signals;

[0029] After the wireless receiving module 16 receives the wireless signal transmitted by the wireless transmitting module 15, its corresponding output pin will also generate a high-level voltage signal, which is connected to the delay relay module 17 to control the on and off of the output relay of the delay relay module 17, thereby controlling the start of the sound and light alarm module 19. At this time, the sound and light alarm module 19 on the shelf B3 layer will issue a prompt message to indicate the location of the item, making it easier to find spare parts.
