[Abstract]:With the development of economy and the progress of technology, people are eager for high quality of life. As a hot industry, smart home has gradually become the focus of attention in the market. Many technology companies have developed their own products, but because of grandiose publicity, unreasonable positioning and high prices, consumers have been deterred by smart home products. In view of this situation, this paper focuses on the low-end industry of smart home, and develops and designs a simple and practical intelligent home control gateway system with low price. The goal is to enable ordinary people to enjoy the fruits of the development of science and technology. The gateway system integrates electronic technology, computer technology, communication technology and other technologies. From the hardware and software aspects of the control gateway in-depth study, and finally achieve the purpose of remote monitoring of the home environment. In hardware, the control gateway system uses single-chip microcomputer as the hardware control platform. With power supply module, clock module, EEPROM module and other peripheral circuit modules as assistance, combined with ZigBee and WiFi wireless communication technology. To complete the building of smart home gateway system. The single chip microcomputer of the gateway system is powerful and cheap based on ARM 32-bit Cortex-based. M3 STM32F103RCT6, it is mainly responsible for the home environment task scheduling, intelligent control; The ZigBee part uses the main chip as the CC2530 wireless communication module, this module mainly includes two parts: the coordinator and the terminal node, the terminal node in addition to the communication part, also includes the temperature and humidity sensor. Light sensor, smoke sensor and other parts, it is responsible for data collection, packaging and sending work. The coordinator is responsible for repackaging the data sent by the terminal node and transmitting it to the main control module through the serial port. The WiFi part uses the low-cost, functional ESP8266WiFi communication module, this module has three working modes: STAAP and STA/AP. The WiFi part has two functions of connecting hot spot and sending hot spot. The module is responsible for the communication between the intelligent home control unit and the outside world. The module communicates with the control unit through the serial port. In software, the control gateway adopts Keil and IAR as the development environment and UC / OS- 鈪，
