In order to solve the problems of high cost, complicated wiring and inconvenient operation of the elevator monitoring system, this paper designs an elevator safety monitoring system based on Internet of things technologies. In this system, the CC2530 acts as a processor and communication module, the DHT11 as a temperature and humidity sensor module, and the ADXL345 as an accelerometer sensor module. The power supply module uses the chip LM2576S to provide 3V and 3.3V voltage. The fault tree analysis method is employed to analyze the reliability of the system designed in this paper. The data acquisition module, power supply module and MCU I/O port are given relatively large weight, which demonstrates that they are more likely to cause system failure. In this paper, the environmental parameters of elevator in a certain residential area are tested. According to the test results, the average relative errors of temperature, air humidity and velocity are 0.47%, 1.40% and 1.36%, respectively. The experimental results show that this easy-to-operate system can monitor the environmental parameters of the elevator with high precision, and can achieve the real-time monitoring on the running state of the elevator.
