Research On Family Energy Saving Control System Based On Internet Of Things

Internet of things is a network technology that connects any items to the Internet,exchange information and communicate with the Internet through various information sensing devices to realize intelligent monitoring and management.In recent years,with the deepening of the concept of smart home and the increasing consumption of household energy,"energy saving" has become an important part of the progress of smart home system.However,energy saving can be achieved to a certain extent through intelligent system to control household appliances.In order to make users more convenient to use electrical appliances and achieve energy saving,this paper designs a remote family energy saving control system,which enables users to monitor the working state of domestic electric appliances in real time.In view of the remote monitoring and control problems of household high-power electrical appliances,the following research is carried out in this paper:1.In order to accurately judge the working state of household electric appliance,the current sensor based on electromagnetic induction principle is used to detect the working current of electric appliance,and the design of measurement and control node is put forward to detect and control the working state of the electric appliance.The control node selects the STM32F030C8T6 of the arm-cortex as the core processor;uses 12 bit ADC in the processor to complete the three channel current information collection,and uses the wireless network communication technology based on Wi Fi to realize the network function of the measurement and control node,and completes the data transmission through the custom data communication protocol.2.In order to facilitate users to control household appliances remotely,the design of mobile client terminal APP and server-side software are proposed.The development of APP is accomplished by using Qt,an application development framework based on cross platform C++ GUI.By using the signal and slot mechanism of Qt,the functions of displaying APP interface,registration,drawing,setting and information view are realized,and the household appliances can be controlled remotely and the information of their work can be viewed.The server software takes the processing of different data information as the core to realize user management,node management,and interactive management with mobile client terminals.According to the above research,this article has carried on the related test.It shows that the system has a stable wireless transmission capacity,can detect the working current of the appliance with high precision,and can realize real-time / timing control of home appliances.The test shows that the system can realize real-time / timing control of household appliances,and has a certain reference value for the development of smart home system.
