The Low Power Intelligent Control System Of Electrical Appliances Based On LwIP Protocol

With the popularity of home networking and home appliances and embedded systems, intelligent control system of electrical appliances began to enter people’s lives, smart home control system is a new resea rch direction based on Internet of things,which can greatly improve the lives of people at home, people at home do not need to manually operate the different remote control or operate switch handly at home, could implement switch of electrical appliances by remote control. User’s quality of life could have a great improvement, therefore, The smart home control system has extensive application prospect.This article have done depth research in view of the indoor wireless network, remote network communication and other key technologies such as cloud platform, introducing the LwIP protocol Ethernet technology and Yeelink remote cloud platform, buliding an intelligent control system of electrical appliances. The system is mainly composed of bluetooth wireless network, Yeelink remote cloud platform, controller station and controlled station, realizing the remote access control of household applian-ces.The paper mainly completed the following work:1.According to the demand and defects of the intelligent control sys tem of electrical appliances, from the construction of system, data transmission mode and working style, propossed The low power intelligent control system of electrical appliances based on LwIP protocol;completed the the hardware design and software programming of the controller station and controlled station, realized the switch of household appliances and temperature data acquisition in the family;studied low power consumption functions of K64 chips we choosed.2.Researched the indoor communication mode, choosing Bluetooth technology as indoor communication mode, According to AT command to complete interior star network form, researched the way of controller station connecting to the Internet,introducing the LwIP protocol,expounded the core part of this agreement:operating of pbuf and TCP protocol, according to the RAW API of LwIP protocol to complete the controller station sending and receiving network data.3.Researched the requirement of Yeelink remote cloud platform to send and receive data format, implemented the embedded system visiting Yeelink remote cloud platform transmission and acquiring data through the Internet, completed the remote control through the cloud platform.4.Introduced the third-party software, such as serial assistant and network assistants, tested hardware and software of intelligent control system of electrical appliances, the test results showed that the system ran stably, consumption was low, easy to use, communication distance met the needs of the indoor system.
