Orchid Technologies Engineering & Consulting Case Study: Elevator Controller

The design of Elevator Control Systems presents a unique mix of sophisticated computer control needs blended with industrial strength power switching requirements. Orchid's primary challenge was to maintain a quiet operating environment for the control microprocessors while holding overall product cost to a minimum. Drawing on Technology from AMD and Microchip Technology, Orchid fashioned an AMD AM80188ER primary control board, and a Microchip PIC16C923 based slave processor. This master-slave combination permits the unlimited, cost effective expansion of control circuits in support of Elevator Control Systems of all sizes. Add to this a display and keypad for maintenance applications.
