With the rapid development of science and technology, residential intelligence is a new revolution in human housing. Families in modern society are becoming more relaxed and productive with the diversified information and safe, comfortable and convenient living environment brought by intelligent home. An orderly and efficient modern lifestyle is an eternal pursuit as an ideal goal. At present, the smart industry has developed rapidly around the world. In the near future, homes without smart home systems will be as out of fashion as today's homes without Internet access. Therefore, home intelligence will be the general trend. In this context, a set of convenient and stable smart home control devices is essential.
This article conducts an in-depth study on the implementation of smart home control devices.
Working principle: The working principle of the device is divided into four parts: remote control module, main controller, slave controller and control circuit. The remote computer and mobile phone communicate with the main controller with Windows CE platform through the Internet network and GPRS network respectively. The main controller and the slave controller are respectively connected to the Bluetooth module through the serial port and communicate through Bluetooth transmission. The slave controller is directly connected to the control circuit, and the household appliances are controlled through the control circuit. The figure below shows the design of the nRF0433 wireless transceiver module circuit.
