On A Working Monitoring System of Manhole Wells Based on Technology of Internet of Things

摘要

The ground cable is usually laid in the underground pipeline, and the manhole is used as the entrance and exit of the pipeline for maintenance of pipeline and ground cable. The loss of manhole cover causes accidents such as pedestrians or vehicles falling into the well and so on, and it often happens to open the manhole cover without permission of authorized units, occupy or compete for pipeline resources, and even lead to cable damage, which seriously affects the safe operation of the network. This system researches and develops the intelligent monitoring system of manhole well, and realizes the monitoring of manhole well status based on the Internet of things technology. The system mainly includes lock well cover, alarm terminal, centralized monitoring server and centralized monitoring client. The lock well cover and the alarm terminal perceive the change of the well cover state, send information to the application layer through the network and notify the user, and the user will process it accordingly. Among them, the application layer is composed of centralized monitoring server and centralized monitoring client. The system is used for the ground cable protection of the three major telecom operators. On the one hand, it protects the resources and market of the operators; on the other hand, it greatly reduces the lack of manhole covers on the road, and avoids a large number of accidents and casualties.
