Design And Implementation Of Smart Home Wireless Gateway Based On Multi-protocol Fusion

With the increasing improvement of people’s living standards,smart home have gradually entered thousands of households.From the initial 485 wired intelligent control system to the promotion of the 433 wireless technology application,and to the popularization of Wi-Fi intelligent single products,the intelligent wireless gateway system has gradually became the focus of research nowadays.At present,the smart wireless gateways in the domestic and foreign markets have a single protocol,poor stability and high cost,and it is difficult to use a variety of application scenarios to meet consumer needs.Therefore,in order to solve the market pain points,this paper designs a wireless smart home gateway solution which is adopt the ESP8266 chip as the main control chip and combines with Zig Bee chip CC2530,Bluetooth chip n RF52832,and we also add the power supply circuit,button circuit,and LED circuit for the solution.In the hardware,we program the firmware of Wi-Fi module based on ESP8266,and program the firmware of Zig Bee module based on CC2530,and program the firmware of BLE module firmware based on n RF52832,and combine the three parts to through with serial port and SPI to realize the protoco l conversion between Wi-Fi and Zig Bee network and WI-Fi and BLE networks to achieves the effect of multi-protocol integration.Terminal interaction is one of the important components of the smart home,which is responsible for releasing user instructions to the gateway to achieve device control.There are many forms of interaction,including voice interaction,APP interaction,gesture control,etc.Among them,APP interaction is the most important interaction method.In this paper,from the analysis of the market share of the two major mobile phone systems which means that is Android and i OS,we choose the Android APP with a higher market share which is selected as the development object.As for the Android APP,we use the Android Studio as the development environment and Kotlin as the development language for development so that we can connect to the smart home system to meet the needs of users for remote monitoring and control equipment.After debugging and testing of the system,we found that the sub-devices,gateways,APPs,and cloud platforms in this system have stable communications and are running well,and they can monitor and control the status of the devices and build linkages in various scenarios to adapt to various application scenarios.
