Elevator solutions

This solution includes 6 major items, including the elevator top-level control system, each floor call panel, the elevator floor button board, the elevator floor access control, the elevator information display panel and the elevator emergency communication system. Nuvoton's full range of products can cover this application.

• Elevator top-level control system: combines elevator control and motor drive, using Nuvoton M487 microcontroller
• Call panel for each floor: using Nuvoton NUC131 microcontroller
• Floor button board inside the elevator: using Nuvoton NUC131 microcontroller
• Information display panel in the elevator: using Nuvoton N329 microprocessor
• Floor access control in the elevator: using Nuvoton M483 microcontroller
• Elevator emergency communication system (five-way intercom): using Nuvoton M481 microcontroller
• Elevator door anti-pinch system: using Nuvoton  M483 microcontroller
