摘要
设计了一种低功耗、快速响应的可远程控制的电导率仪。仪表以S3C2440作为核心控制处理器,采集节点外部设有复位电路、按键输入模块、采样电路、精密整流电路、LCD显示电路、储存模块和电源部分,另外还有温度补偿功能。系统通过MODBUS总线实现控制系统与采集节点之间的相互通信,完成嵌入式系统远程对现场节点信息的监控。
A low-consumption and high-response conductivity analyzer which can be remotely controlled was designed, and it has S3 C2440 microcontroller employed, and the reset circuit, keyboard input module, sampling circuit,precision rectify circuit,LCD display module and storage module as well as the power module set out-side of the acquisition node, meanwhile, it has temperature compensation. The system communicating with acquisition nodes via MODBUS can accomplish monitoring of the site nodes.
