Research On Water Quality Monitoring System Of Drinking Water Sources In Rural Areas Based On GPRS Technology

In recent years, the situation of water pollution in China is increasingly serious, including drinking water quality also has been a very anxious. Compared with the water pollution in cities, the pollution of rural drinking water sources is more serious. Due to the common backward water treatment technique of villages and towns, lack of necessary factors of water quality monitoring equipment, rural drinking water sources pollution will not be able to get timely treatment. In order to solve this situation, this paper puts forward a set of fairly perfect rural drinking water sources of water quality monitoring system solutions.This article firstly introduces the research significance and current development situation of the rural drinking water sources quality monitoring system, and the overall design of the system and some key technologies used in this system has carried on the deeper research and discussion.Secondly, based on the analysis of the overall design of the system, field monitoring data acquisition part of the system is introduced in detail. The data acquisition part of this system includes the water quality sensor information acquisition and the monitoring scene image acquisition two parts:water quality information acquisition part uses microcontroller to control sensor to collect the water quality parameters, and the collected data through the GPRS module to send to GPRS Server; image acquisition of monitoring field uses MCU and GPRS module integrated development board to control serial camera to collect picture and sent to mobile phone users.Thirdly, based on the problem of the water quality sensor will accumulate some dirt in the water for a long time and not easy to clean up, design a set of ultrasonic cleaning device. The device puts the water quality sensor fixed on the screw slide table, through the single chip microcomputer to control stepping motor running so as to control the rise and fall of screw sliding table, using ultrasonic generator making ultrasonic in a sealed small scale, to clean the stigma surface of variety of water quality sensors.Finally, this article is based on B/S mode to write the PC monitoring software. Using ASP.NET technology to realize the dynamic web page access Server SQL Server database, real-time display and monitoring data of water level in real-time evaluation, query the data and real-time dynamic curve drawing, etc.This article uses the water quality sensors and serial camera combined with GPRS technology, and integrated water quality sensors ultrasonic cleaning system, design a set of relatively complete rural drinking water quality monitoring system, it can realize remote monitoring water quality data and transmission the scene picture to user’s mobile phone, and can use the ultrasonic cleaning system to clean water quality sensors to ensure the accuracy of the sensor measurement data and its service life, and to guarantee rural drinking water safety and water environment protection is of certain practical value, the system flexible, low manufacturing cost, simple operation, accurate measurement, can be used widely in the field of water quality monitoring.
