What does a group controller do?

• A. It manages the electrical connections in the elevator
• B. It coordinates the movement of multiple cars
• C. It regulates the speed of individual cars
• D. It monitors power supply to the elevator system

Answer: (B)

A group controller is essential in elevator systems that involve multiple cars operating within the same building. Its primary function is to coordinate and manage the movement of these cars to ensure efficient operation and optimal service to the passengers. By doing so, the group controller can minimize wait times, manage traffic flow, and enhance the overall efficiency of the elevator system. In scenarios where multiple elevators share the same shaft or are servicing the same group of floors, the group controller intelligently receives calls from the elevators and determines which car should respond to which request. This optimizes the scheduling and reduces the number of stops each elevator makes, thereby improving performance and energy efficiency. Understanding this function of the group controller is crucial in the context of modern elevator systems. It effectively allows multiple elevators to work together seamlessly rather than operating independently, which can lead to delays and inefficiencies.
