PrecaElevator: Towards Zero-Waiting Time on Calling Elevator By Utilizing Context Aware Platform in Smart Building

Elevator system faces a serious challenge of reducing waiting time for passengers because of the computation limitation of the stand-alone elevator system. In this article, we present our proposal-PrecaElevator, a novel elevator system in smart building that enables passengers to reduce their waiting time through pre-registering elevator calls. After upgraded a traditional elevator to Internet of Things (IoT)-enabled and transferred the real-time computational capability to the agent server, the elevator was upgraded as a smart object computing on context awareness in both elevator and passengers. By leveraging BLE-based localization of the passenger, PrecaElevator enables the passenger to pre-register elevator call if his/her location was detected within the callable range for elevator control. We have experimented the proposed system in the real smart building environment. The simulations based on the calculated waiting time from elevator historical records showed the effectiveness of waiting time reduction.
