摘　　要：本文设计了一种基于SI4463射频芯片的无线数据采集模块。数据采集终端选用MSP430F149为核心微处理器芯片,选用SI4463作为射频通信主芯片,实现对雨量、水位、土壤水分等水文信息的短距离无线传送。本设计主要有硬件和软件两部分,软件设计部分重点讲了低功耗和时间同步问题。该数据采集终端具有低功耗、低成本、可靠性高等特点。This paper describes the design of a wireless data acquisition module based on SI6643 RF-chip. Data acquisition terminal uses MSP430F149 as the main microprocessor chip, SI4463 is chose as the main chip of RF communication,achieve the short distance transmission of the hydrological information which include the rainfall, water level,Soil moisture and so on. This design mainly has two parts： hardware and software, the software design part focus on low power consumption and time synchronization. This data acquisition terminal has some characteristics as follow： low power consumption, low cost, high reliability and so on.
