Design and Implementation of Distribution Well Safety Monitoring System Based on ZigBee

Distribution wells in buildings are the blind spots for security monitoring and are prone to safety accidents. In order to make up for the shortcomings of security monitoring, this paper reduces the workload of manual inspections of distribution wells, and reduces the probability of accidents caused by distribution wells, and short distance wireless communication technology ZigBee was used to network the Internet of Things perception layer. DTU was used for network layer access, and MQTT protocol was adopted for message subscription and publication by the application layer. We designed and implemented a distribution well security monitoring system, which used data fusion from multiple sensors to determine whether the system was safe and to decide whether to alarm. The system makes up for the shortcomings of the fire monitoring system. Signals from the distribution well safety monitoring system can be extended and connected to the fire monitoring system, expanding the monitoring range of fire monitoring.
