Abstract

With the rapid development of modern society, along with increasingly serious water pollution problem has become a major obstacle to human survival. Therefore, the prevention and control of water pollution has become the focus of world concern. Draw on the experience of foreign water pollution monitoring, monitoring of water pollution has also made very rapidly, but has not been widely used because of the backwardness of the technical means of online water quality monitoring system. The study in the subject line water quality monitoring system based on ARM and GPRS in contrast to the original artificial means of monitoring or low processing power monitoring system has made a lot of progress, the real-time status on the correct evaluation of sewage, type of pollutants pollution levels has important significance. Wireless communication technology continues to evolve and mature, increasingly multiplied and wireless communication networks in industrial data transmission. Compared with the real-time online launch of China Mobile's GPRS wireless communication technology and other wireless communications technology makes it low cost in a short period of time in the small users to set up their own cross-regional data network traffic accounting, fast and landing have greater advantages. In addition, a hot technology in the current 32-bit ARM processor-based embedded systems technology, 32-bit ARM has the characteristics of small size, low power consumption and high frequency, peripherals and more also more widely be applied to the field of industrial control, wireless communications, network applications, consumer electronics, imaging and security. The topics to be ARM and GPRS technology applied to the sewage line water quality monitoring system, the entire system design is divided into three parts: sub-stations, the monitoring center and communications network. In view of the huge, this article only to complete the design of the sub-stations and communication networks. Sub-stations to achieve some of the indicators of water quality and traffic data collection, and the collection of data for high-speed processing, storage and transmission to the monitoring center and can accept the instruction of the Monitoring Center, and at the same time be able to set some system functions, and through lcd display. The monitoring center is responsible for real-time display and send commands to the sub-stations, water quality data query, save and print functions. GPRS communication network data transmission sub-stations and monitoring centers, the primary means of communication is based on the TCP / IP protocol on the basis of the establishment of connection-oriented communication, this can be a good guarantee of the correctness and security of the data transmission. Sewage treatment line monitoring due to some water quality indicators can not by hardware-line monitoring, and can only be measured by laboratory tests of the method, it will cause serious lag, response time may lead to serious consequences, so the system through the establishment of fuzzy neural network soft sensor model simulation experiments, to replace hardware monitoring and software monitoring to verify the feasibility of modeling and simulation.
