Design of Monitoring System for Height Limiting Device Based on Acceleration Sensor

Abstract

In view of the actual use of height limiting devices at home and abroad and the requirements of relevant standards, the system uses three-axis acceleration sensors and high-definition network cameras as the state detection devices of height limiting devices. When an accident occurs when an ultra-high vehicle hits height limiting equipment, the acceleration sensors collect the spatial position information and acceleration information of height limiting devices and transmit them to the cloud through NB-Iot. At the same time, the 4g network camera is ordered to collect pictures and video information within the specified time and transmit them to the cloud server, and all data in the cloud server are obtained at the management terminal, which is convenient for comprehensive analysis of accident information and unified command and dispatch. Experiment show that that system can stably monitor the health status of height limiting device, and give timely and accurate remote alarm in case of super-high accident, It is a safe and effective monitoring system for height limiting devices.
