[Abstract]:With the development of technology, short-range wireless communication technology has been more and more widely used in people's working life. The existing short-range wireless communication technology has many technical standards, such as ZigBee, Bluetooth, Wifi and so on. Compared with other short-range wireless transmission technologies, ZigBee has the advantages of long transmission distance, high network expansibility, large number of network nodes and low power consumption. In addition, with the popularity of intelligent mobile devices, short-range wireless communication technology combined with intelligent mobile devices is becoming more and more important. Android is the first intelligent mobile operating system with market share, which combines ZigBee technology with Android mobile devices. The advantages of ZigBee, such as low power consumption, low cost, easy networking and Android portability, can be integrated to meet the needs of short range mobile wireless communication. A communication system based on ZigBee technology and Android platform is designed and implemented in this paper. The reliability of data transmission is analyzed in detail from the aspects of ZigBee wireless network transmission and serial port transmission between ZigBee and host computer. The transmission mechanism is improved to ensure the reliability of data transmission under the condition of continuous transmission of a large amount of data. The file management and transmission software is developed according to MVC mode, which realizes the function of file management and receiving, and realizes the communication between Android and ZigBee through the transmission of ZigBee to serial port, the conversion from serial port to USB, and the reading and writing of USB data by Android.
