基于无线传感技术的水位数据采集系统设计

摘要

根据康扬水电站计算机监控系统中水情测报分系统的需要，提出一种基于ZigBee无线传感技术的水位数据测量采集系统方案。给出测量系统的系统构架和功能分析，并针对传感器和协调器节点进行硬件方案设计；介绍网络节点中LPC2210与MC13192模块之间SPI通讯实现过程；借助MCGS的驱动开发接口函数，设计串口设备驱动程序。系统投入实际运行后，成功地实现对现地水位数据的采集与无线传输，运行稳定可靠，证明了这一方案设计的合理性。%Aimed at the need of the water regime forecasting system of kangyang hydropower station, the water level acquisition system is proposed based on ZigBee WSN technology. The integral framework and functional analysis for the measuring system are put forward. And the hardware scheme of the sensor and coordinator node is designed. Then, the SPI communication process between the LPC2210 and the MC13192 module are introduced. Utilizing the MCGS interface function, the serial device driver is designed. After putting into practical operation, the system successfully realizes the local water level data acquisition and wireless transmission. It proves the rationality of the scheme design by stable and reliable running.
