采用zigbee技术实现基于mems传感器的无线传感网络节点小型化设计,组成的小型化系统可用于航天器各仓段内部温度、湿度、压力、加速度等状态参数的监测。小型化无线传感网络采用集中供电方式即可以减小节点体积,又便于后续电池更换。传感器信号无线传输方式,可以大大减少航天器电线电缆的数量、减小布线带来的困难及航天器总体质量。
The zigbee technology is used to realize the miniaturization design of wireless sensor network node based on mems sensor. The miniaturized system can be used to monitor the temperature, humidity, pressure, acceleration and other status parameters of spacecraft. Miniaturized wireless sensor network using centralized power supply can reduce the node size, but also facilitate subsequent battery replacement. Wireless sensor signal transmission, can greatly reduce the number of spacecraft wire and cable, wiring to reduce the difficulties and the overall quality of spacecraft.
