Intelligent Energy Saving Control System Based on OneNET Cloud Platform and MQTT Protocol of Internet of Things

面对传统节能控制系统电能耗费大、实训室管理不全面,导致节能控制效果较差的问题,提出基于OneNET云平台与物联网MQTT协议的智慧节能控制系统;选择HTML5-20工控板,支持MQTT协议,并与单片机通信;使用MLX90614型号红外温度传感器,通过探测辐射情况,实现高精度温度测量;设计HC-SR501人体红外感应模块,监控实训室设备安全使用情况,避免出现电能消耗大的情况;根据系统软件部分功能模块,通过手机app端移动设备控制教室设备,并随时监管设备运行状态;将远程智能控制接入OneNET平台,实现机构管理员管理、设备运行报表和自动检修功能;由系统测试结果可知,该系统风扇最少耗电为40 W、电灯最少耗电为0.1度,说明电能消耗较少;实训室温度和湿度均在正常监管范围内,说明实训室处于安全状态;该系统设计从节能、安全管理角度,解决实训室的智能管理问题,也为资产失窃防患提供保障。

Faced with the problems of high power consumption based on cloud platform,IoT smart energy-saving control system,and insecure management of the training room,resulting in poor energy-saving control effects,a smart energy-saving control system based on OneNET cloud platform and IoT MQTT protocol is proposed.Choose HTML5-20 industrial control board,support MQTT protocol,and communicate with single chip microcomputer.MLX90614 infrared temperature sensor is used to detect radiation to achieve high-precision temperature measurement.Design the HC-SR501 human body infrared sensor module to monitor the safe use of equipment in the training room to avoid large power consumption.According to some functional modules of the system software,the classroom equipment is controlled through the mobile device of the mobile phone app,and the operating status of the equipment is monitored at any time.The remote intelligent control is connected to the OneNET platform to realize the functions of institutional administrator management,equipment operation reports and automatic maintenance.It can be seen from the system test results that the minimum power consumption of the system fan is 40 W and the minimum power consumption of the lamp is 0.1 degrees,indicating that the power consumption is less;the temperature and humidity of the training room are within the normal supervision range,indicating that the training room is in a safe state.The system design solves the problem of intelligent management in the training room from the perspective of energy saving and safety management,and also provides protection for asset theft prevention.
