AI Technical Summary

Problems solved by technology

[0004] The traditional touch query all-in-one machine with indication function has a single query method, except for touch query and button query, there are no other query methods, which affects the user query experience

The power supply part of the traditional touch query all-in-one machine uses many components, the circuit structure is complex, the hardware cost is high, and it is inconvenient to maintain

In addition, due to the lack of corresponding circuit protection functions in the power supply part of the traditional touch inquiry all-in-one machine with indication function, for example, the lack of current limiting protection function, the safety and reliability of the circuit are poor
