Abstract
A system and method for remotely monitoring the operation of elevators to determine elevator shutdown. A control box is mounted to each elevator that includes one or more sensors that can detect movement of the elevator, a processor that can process data received from the sensors and a communications device that can transmit the processed data. The method includes determining a usage rate of movement of each of the elevators in the processor using the data, transmitting the usage rate from each of the communications devices to a remote server, and comparing the usage rate of each of the elevators to the usage rate of the other elevators in the server. The method then determines that one of the elevators has shut down or has a low performance if its usage rate is significantly different than the usage rate of the other elevators.
