AI Technical Summary
Existing elevators lack voice reassurance functions during power outages, causing passenger panic. Furthermore, the absence of automatic rescue systems prevents passengers from operating the call button, posing a safety risk.
An elevator power outage reassurance and automatic call for professional rescue personnel system was designed, including a main control board, an emergency power supply for power outage output, a voice board, a communication-type weighing instrument, and a call button car intercom auxiliary unit. It is connected to the speaker and intercom host through a CAN communication bus to realize voice reassurance and automatic call functions.
When the elevator loses power, it reassures passengers with voice announcements, automatically detects passengers' presence and triggers the call button, ensuring passengers can safely wait for rescue and avoiding panic and safety risks.
