Abstract: Aiming at solving the problem that elevators encounter failures frequently, Internet interaction was applied to the elevator monitoring and alarm system. Classification model for failures of elevators was built, which consists of the running statuses of elevators and the breakdown diagnosis.The classification model clears different running statuses of elevators and definites the judgement standard of elevators′ failures. Based on it, operational monitoring and alarm terminal with MCU at the core was developed. The running speed, floor, direction and passenger status were gotten through the method of standalone sensor information acquisition. Meanwhile, module of online audio and video based on H.264 was integrated in the system, the functions of video surveillance of the elevators and voice communications with passengers in the elevators were provided. During several pilots, the system can make the control center receive the accurate information of running statuses of elevators, and the clear realtime images in elevators through the Internet. Also, the control center can remotely interact with passengers in the elevators. The results of the pilots show that, the system makes the remote monitoring of elevators more reasonable and effective.
