Special Features: When a resident enters the elevator, the AI ​​behavior-sensing camera recognizes their face, retrieves the corresponding user from the database, and sends their floor number to the C51 microcontroller. The microcontroller's I / O ports then control the floor selection. After activating the elevator, the user can use voice control to go to different floors. This function is for users with mobility issues or those unable to touch buttons in emergencies. If the person entering the elevator is on the blacklist already entered by the embedded AI server, an alarm will be automatically sent to the administrator via SMS. If a resident experiences a sudden physical emergency while riding the elevator and is unable to use it, they can wake up the elevator assistant via voice commands. The system controls elevator floors and allows users to call management personnel. The C51 microcontroller core controller interfaces with elevator buttons via I / O ports to obtain their current status or control changes to their status. It also connects to the voice module and embedded AI server via serial port. The voice recognition module 4 provides human-machine interaction and user service functions.

Furthermore, the AI ​​recognition function allows for multimodal voice interaction to meet user needs. The emergency intercom system is used for emergency response, enabling remote SMS and telephone alarms and facilitating communication between the elevator and the outside world. It collects and distributes data via a locally embedded AI server; performs facial recognition using an AI behavior-sensing camera and sends the data to the embedded AI server; analyzes the data from the embedded AI server's database and distributes the results to a C51 microcontroller for logic processing; uses voice recognition to identify voices and requests to control elevator floors; enables remote telephone calls and SMS sending via a communication module; and allows for secondary modifications to the existing elevator's basic panel through modular design.
