摘　　要：介绍了利用LPC2468处理电导率、温度传感器等所采集的信号,使传感器的测量由手控转变为自动化,且其精度大大提高。提出使用传感器、ADC7656芯片、AD7502芯片等建立基于LPC2468的水质监测系统,利用DM9000芯片实现单片机与计算机之间的通信,同时用μC/OS-II开发采集系统的控制程序。This paper introduced how to use LPC2468 to deal with the signal acquisition by conductivity, temperature sensors and so on.This system makes sensor testing change from manually operation to automation, which can raise the precision of testing,It offers that computer can be connected to single chip processor by DM9000.We can use sensors,AD7656,AD7502 and so on to built water quality monitoring system based on LPC2468.
