基于 MSP430 的灌区无线传感点对点通信系统设计

摘要

为解决我国传统农业用水利用率低的现状，针对现代化灌区监测所面临的布线复杂、安装维护麻烦等问题，以MSP430单片机为核心，SI4463作为射频芯片，结合电源、存储、数据采集等模块为灌区智能监测系统设计一款无线传感通信系统。简单的时钟同步设计和传输协议使系统能更加快捷地进行数据传输。系统根据灌区温度、雨量、土壤墒情等环境情况，设计不同的传感器采集电路用以采集并传输，是一款符合水文监测要求的智能监控系统通信模块。%To change the status of water utilization rate of China's traditional agricultural low, according to problems of complex wiring facing by modern irrigation monitoring, trouble of installation maintenance and other issues, based on MSP430 MCU as the core, SI4463 as a radio frequency chip, combined with power supply, storage and data acquisition module, it designs a wireless sensor communication system for irrigation smart monitoring system. Simple clock synchronization design and transmission protocol make the system more efifcient for data transmission. According to the environment of irrigation area of temperature, rainfall, soil moisture content, the system has different sensor acquisition circuits used in acquisition and transmission. It is the intelligent monitoring system communication module meeting the hydrological monitoring requirements.
