Elevator Control System is the system responsible for coordinating all aspects of elevator service such as travel, speed, accelerating, decelerating, door opening speed and delay, leveling and hall lantern signals.
It accepts inputs (e.g. button signals) and produces outputs (elevator cars moving, doors opening, etc.).
The main aims of the elevator control system are:
• To bring the lift car to the correct floor.
• To minimize travel time.
• To maximize passenger comfort by providing a smooth ride.
• To accelerate, decelerate and travel within safe speed limits.
Types of elevator control systems:
There are 3 main types of elevator control systems as follows:
1. Single Automatic operation:
• First automated system w/o single call button on each floor and a single button for each floor inside car.
• Called if no one is using it.
• Passenger has exclusive use of the car until rip is complete.
2. Selective collective operation:
• Most common, remembers and answers calls in one direction then reverses. When trip complete, programmed to return to a home landing.
3. Group automatic operation:
• For large buildings with many elevators which are controlled with programmable microprocessors to respond.
