摘要
针对目前温度、湿度等数据采集监测系统功耗大、应用场合有限等缺陷,设计一种基于MSP430系列微处理器的低功耗无线传感器节点。硬件设计基于Moteiv方案,采用超低功耗单片机MSP430F1611作为数据处理芯片,以CC2420无线射频芯片作为收发芯片,并拥有JTAG以及其他扩展接口。通过合理设计电路来降低设备功耗,提高设备的能量利用率,从而达到提高无线传感器网络的稳定性和可靠性,延长网络生命周期的目的。
According to the temperature, humidity and so on data collecting and monitoring system of large power consumption, application of defects such as limited, designs low power consumption wireless sensor node based on a microprocessor of MSP430 series..Hardware design based on Moteiv scheme, uses ultra low power MCU MSP430FI611 as the data processing chip, CC2420 radio frequency chip as the transceiver chip, and has JTAG and other extended interface. Through the reasonable design of circuit, reduces device power consumption, improves equip- ment utilization rate of energy, so as to improve the wireless sensor network stability and relia- bility, prolongs the objective of network life cycle.
