摘要: 为解决水利自动化监测工程中有线连接布线复杂、可靠性下降、防雷困难的问题,设计了一款体积紧凑、易于组网的无线应变采集装置。该装置通过半桥式电桥和精密仪表运算放大器完成应变信号的调理,采用最新的射频片上系统CC2530完成电压信号的数字化及无线传输。基于TI公司的Z-Stack协议栈构成的无线传感器网络节点具备良好的自组网特性及网络自愈功能,并且通过休眠设置确保了无线传输的低功耗。

Abstract: Fixed wire connection in the automatic monitoring system of water project is featured with complex wire routing, inadequate reliability and has difficulty in thunder protection. In view of this, a volume-compact, easily-connected wireless strain collector is proposed in this paper. The collector modulates the differential strain signal by half-bridge and precise instrumentation amplifier, and employs an up-to-date RF (radio frequency) system (CC2530) on chip to realize digitalization for analog voltage signal and wireless transmission. The wireless sensor nodes based on TI’s Z-stack protocol possess high performances of network self-organization and network self-healing, and support low power consumption in wireless transmission by sleep mode.
