摘　　要：针对智能化电气设备普及带来的用电能耗、用电风险提高等问题,设计了一种基于NB-IoT的学生宿舍智慧用电监控系统。系统监控终端与学生宿舍唯一绑定,可以实时收集宿舍电压、电流、电功率等数据,并通过NB-IoT无线通信方式上传云平台。若监测到学生违规用电,监控终端立刻切断电源并将违规用电信息发送至管理员。云平台实现数据加工、存储,并通过APP将数据可视化展示。管理员可通过APP远程控制室内用电通断、下发监控阈值等。经测试,所设计的系统使用便捷、运行稳定、具有较高的实际使用价值。Aiming at the problems of increased electricity consumption and increased risks caused by the popularization of intelligent e-lectrical equipment,a smart electricity monitoring system for student dormitories based on NB-IoT is designed.The system monitoring terminal is uniquely bound to the student dormitory,which can collect dormitory voltage,current,electrical power and other data in real time,and upload it to the cloud platform through NB-IoT wireless communication.If a student’s illegal use of electricity is detected,the monitoring terminal will immediately cut off the power supply and send the illegal electricity use information to the administrator.The cloud platform realizes data processing and storage,and displays the data visually through the APP.The administrator can remotely con-trol the on-off status of indoor power consumption and issue monitoring thresholds through the APP.After testing,the designed system has the features of high accuracy,stable operation and high practical value.
