基于MSP430单片机的低功耗RTU设计

The Design of Low-Power RTU Based on MSP430 Single-chip Microcomputer

以低功耗单片机MSP430为MCU,设计一种应用于微灌智能测控系统的低功耗RTU,可完成水情、墒情信息的采集和灌溉设备的控制。在分析MSP430单片机特点的基础上,从工作方式、硬件和通信方式等方面详细介绍了RTU的具体设计。该RTU具有低功耗,高可靠性,具有一定的通用性,在现实中具有极高的实用价值。

This paper gives focus on the design of a low-power RTU based on MSP430 single-chip microcomputer.The RTU can be used in micro-irrigate intelligence measuring and controlling system to collect water regime and soil moisture information and to control irrigation equipment operation. By analyzing traits of MSP430 single-chip microcomputer, design for the RTU is presented in detail from aspects of working mode, hardware and communication me thbcls. The RTU has characteristics of low power, high reliability, certain generalities, and is of high use value.
