Elevator Control System

The solution includes six top-level control systems for elevators, call panels on all floors, floor button on the ladder, access control inside the ladder, information display panel in the ladder, and emergency communication system for elevators. Nuvoton products are suitable for this application.

Elevator top control system: combined with elevator control and motor drive, using NuMicro M487 microcontroller
Calling panel for each floor: Adopting the NuMicro NUC131 microcontroller
Inside floor key pad: Adopting the NuMicro NUC131 microcontroller
In-situ information display panel: using NuMicro N329 microprocessor
Intra-floor access control: using NuMicro M483 microcontroller
Elevator emergency communication system ( five-party intercom ): Adopting the NuMiro M481 microcontroller
Elevator door anti-trap system: using NuMicro M483 microcontroller
