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
