* 1. Mengxin Alliance---》Two technical Mengxins from the technology nebula, determined to carry forward the Mengxin spirit, and always believe that good things are coming!
* 2. The increasing popularity of smart homes has greatly improved our lives. Faced with more and more smart homes, many people will wonder if there is a product that can control the new generation of smart homes while also controlling traditional home appliances to avoid the waste of home appliances and bankruptcy caused by replacement. In response to this user demand, we have designed this smart home central control, which is connected to the Tmall Genie life platform through the onboard wifi module. On the basis of being compatible with the new generation of home appliance control, it adds infrared modules and learning algorithms to achieve harmless transformation of traditional home appliances. While saving wallets, let us also experience the services of smart homes and let technology serve us better!

* 1. Describe the project details.

With Lichun Central Control as the core, combined with Tmall Genie to build a smart home network, it covers the harmless transformation of old home appliances, compatibility with new home appliances, and has autonomous learning capabilities. You can create a comfortable and safe home just by moving your mouth. This project adopts a dual-processor architecture, using GD32 as the main processor and esp8266 as a coprocessor. GD32 is responsible for infrared encoding and decoding, infrared learning, peripheral control and sensor information collection functions. esp8266 is a coprocessor responsible for network data interaction, docking with cloud servers, encoding and decoding data sent by the server, and helping the controller to get on the fast track of the network. In the process, the self-developed protocol learning algorithm is used to realize the intelligent learning of the infrared protocol of traditional home appliances. After testing, the learning accuracy rate can reach 98%, completing the harmless transformation of old home appliances. At the same time, it is connected to Tmall Genie, compatible with most of the smart homes on the market, and ultimately achieving the goal of smart homes.
