To realize the function of parameter monitoring on water quality at different monitoring site function of connecting with control room

data displaying

analyzing and processing and off-limit alarmingis realized at the same time

online real-time monitoring system based on PIC18F6722 and technology of GPRS is designed.The structure of the whole system and the realizing way of the software

and gives the details of hardware design are given.The engineering practices show that multiple parameters water quality on-line monitoring system can simultaneously deal data from different monitoring sites and can remote monitor whole system

so it has a broad prospect of application in villages and towns’ water works.
