Design And Implementation Of Intelligent Home Terminal Control System Based On OpenWrt And BLE

With the implementation of the national science and education strategy to improve people's standard of living requirements,mobility,intelligence,everything is interconnected lives of people living in the three future trends.Past 20 years,driven by smartphones and rapid development of mobile Internet,smart home is emerging rapidly.Today,the smart home industry ushered in an era full of opportunities,open source operating system,sophisticated wireless communication network and cloud platform for developers to open a green channel,and the sensor,processor and storage semiconductors cost dramatically.But there are also many problems,the smart home industry is still no uniform standard,most implementations tendency of large and cumbersome to install,user experience is poor,expensive and so on,they will be the smart home industry to the civilian population must be addressed stumbling block.Main work carried out as follows:1.Designed and implemented by Bluetooth,voice and Wi-Fi are three ways to control a smart home power switch controller.Designed the components on the circuit,PCB circuit and Android UI interface,which can be applied to Android phone,tablet,Bluetooth control program implementation process,It changed the traditional home wiring patterns,wiring-free switching and that can also be compatible with the existing line layout,but also It is being with a variety of smart home systems seamlessly.With thermal imaging experiments tested the effect of ambient temperature of the controller,and the performance of the controller to do a comprehensive analysis and research.2.Stability,security,and easy to extend the principle of facilitating the construction,planning and communication protocol intelligent home networking throughout the terminal control system,Oh ye router based on openWrt system were selected to converted into the intelligent home gateway.CO sensors to monitor the alarm,for example,experiments to verify the feasibility of the whole system.3.This article uses the Bluetooth networking,ZigBee relative to lower power consumption.In the field of consumer electronics,Bluetooth has more advantages,has also been more and more popular.With Bluetooth ad hoc network technology(BLE Mesh)release,to further regulate the Bluetooth-based communication IPv6 packets exchanged between devices to overcome the shortcomings of short-range communications and restrict communication topology,can be immune to electromagnetic interference.Another big advantage is that Bluetooth can be connected directly to the mobile phone will become the main direction of short-range communication development.Attention: The third chapter is a developed independent power switch controller which will be ready to get access tomarket products,and later Bluetooth CSR manufacturers have cooperation,which provides CSR1010 Bluetooth chip and developed API,so the structure of the entire smart home terminal control system,the entire system inner member selected Bluetooth chips are using vendor-provided CSR1010 chip formation BLE mesh network.
