I. Introduction
With the development of social economy, elevators have become more and more popular. Elevators bring convenience to people's work and life. At the same time, the safety of elevators is becoming more and more important.Elevator accidents occur all over the world every year, and serious accidents will cause casualties. Therefore, how to grasp the running status of elevators and existing safety hazards in real time to prevent elevator accidents is one of the directions of the current elevator technology development [1]–[2]. The Internet of things technology has brought new elements to the development of elevators [3]–[5]. Through the monitoring of key components and operating environment of elevators, the occurrence of elevator failures can be reduced. At the same time, when people are trapped in the elevator car, the community monitoring center and elevator maintenance personnel can obtain information at the first time and carry out rescue [6]–[8]. This paper proposes an elevator remote monitoring system, which can monitor the relevant parameters of elevator operation in real time, reduce the probability of elevator failure and deal with it at the first time after elevator failure.
