Design and implementation of running state monitoring system based on WSN

摘要

This paper designs and implements a monitoring system for the running state of the minerals development equipment based on wireless sensor network, which can solve many problems. For example, minerals development equipment of Qinghai is fault-prone, and it is difficult to monitor wiring, and it cannot meet the demand of real-time monitoring for the manual inspection. The system sensor nodes collect working current and voltage of the equipment, and achieve connection between WSN short-distance wireless communication and remote Internet via gateway. Users can monitor and manage on the running state of the equipment in real time through the monitoring center ultimately. Field-based installation and testing of system suggests that the average packet loss rate of the network is 0.19%. The transmission of the sensor data is reliability and stability within 30 meters of communication range and larger than 1 dB of nodes power, which can meet the demand of monitoring the operation state of equipment.
