基于SI4432的无线通信系统设计与实现

摘要

短距离无线通信的应用已经越来越广泛,如何在保证通信质量和安全的前提下,降低系统能耗,减少硬件成本成为制约其发展的关键问题.文中采用ISM频段SI4432射频芯片和ATmega16控制单片机设计了一种新的无线通信系统,完成了系统硬件的搭建,无线通信程序及上位机界面的设计.该系统可在休眠与唤醒两种模式下工作,降低了系统整体能耗,实现了低功耗、小体积、高灵敏度的无线数据传输,可应用于工业控制、智能建筑、远程监控等多个领域,具有广阔的应用前景.%The application of short-range wireless communication technology is more and more widely. How to reduce energy consumption and hardware cost becomes a key to restrict the development of wireless communication when maintain the safety and stability of data transmission. This paper focuses on the construction of the system hardware, the software process design of the wireless communications and offers a humanized operation interface of upper machine. The system can work in awakening mode and sleeping mode, thereby reducing its energy consumption. This system implements a high quality wireless data transmission under the conditions of low power consumption, small size, high sensitivity and has a board application in many areas such as industrial control and smart home.
