基于物联网的学生宿舍安全用电监测系统设计

Design of Monitor System for Student Dormitory Safety Utilization of Electric Power Based on Internet of Things

学生宿舍安全用电监测是安全用电的关键措施。针对以前的监测系统存在的用电负荷过重引起火灾隐患无预警和信息实时性较差等缺陷,在传感器上,选择了温度传感器监测用电导线的温升;漏电传感器监测线路漏电情况;电压电流互感器监测用电使用情况。在信息传输上,利用物联网技术实现监测信息的实时传输,利用2G/4G网络将监测信息传输到手机。设计了系统的硬件和软件,对系统进行了实验测试,测试结果表明,所设计的监测系统能在参数超限时断电,大大提高了学生宿舍的用电安全,具有较好的实用价值。

Monitor system for student dormitory safety utilization of electric power is a key measure for safe electricity consumption.In view of the shortcomings of the previous monitoring system,such as no early warning for fire hidden trouble caused by overload of electricity,poor real-time information transform and so on,in terms of sensors selection,the temperature rise of power line was monitored by temperature sensor;the leakage condition of the line was monitored the leakage sensor;and the use of electricity was monitored the voltage and current transformer.In terms of information transmission,the information was transformed to the mobile in time by the internet of things technology using 2G/4G internet.The paper designed the hardware and software of the system and made some tests about the system.The experimental result revealed that the designed monitor system could cut off power when the parameter exceeded the limit and greatly improved the safety utilization of electric power in student dormitories,which had good practical value.
