The Research Of Sewage Online Montor System Based On ARM And GPRS

With the rapid development of modern society,more and more serious water pollution problem has become a major obstacle to human survival. Therefore,prevention of water pollution has become the focus of worldwide concern. Drawing on foreign experience in water pollution monitoring system,monitoring of water pollution in China has also developed very rapidly,but the backwardness of techniques,water quality online monitoring system has not been widely used. Based on ARM and GPRS online monitoring system is made great progress in real time on the correct evaluation of water status than the original manual monitoring instruments or monitoring systems with low processing power, the type of pollutant ,the degree of pollution has an important significance.The development and mature of wireless communications technology make that more and more industries begin take wireless communication system as data transmission.The GPRS service released by CMCC has many advantages than any other,for example,it can provide real-time online,charging by data flow and fast landing and So on,which make it owna greater advantage in small and medium-sized customers who build their own inter.Regional data networks in a short period of time with a low cost.In addition.the embedded system based 32 bit ARM processor is a hot technology,it has a small size,low power consumption,higher frequency and So many peripherals,So it is being widely used in the fields of industrial control,wireless communication,network applications,consumptive electronic products,image processing,security,etc.The water quality online monitoring system is divided into three parts: sub-station, monitoring center and communications network. In view of the huge system, this article only completed the sub-stations and communication networks's research and design.Sub-stations major to collect some water quality and flow data,especially use of camera images of sewage collection,the high-speed data acquisition processing,storage and transmitted to the monitoring center and monitoring center can accept the instruction,set up some system functions,and through lcd display. Monitoring Center is responsible for real-time display and send commands to the sub-stations, and water quality data query,save and print functions. GPRS communication network transmit datas between sub-stations and monitoring center, the main means of communication is based on TCP/IP protocol,based on connection-oriented socket communication,so that data can be very good to ensure the accuracy and security of information transmission.Online monitoring of waste water quality objectives can not be due to some hardware-line monitoring,laboratory testing methods may detect them but it would seriously delay the feedback of time,may lead some serious consequences,so the Soft-measuring Technique through establishing the fuzzy neural network Soft-measuring Technique model simulation,can replace hardware monitoring.
