Water Quality Monitoring System Based On GPRS Communication Module

Since the formal access to the Internet in mainland China in 1994,China's Internet technology has seen rapid development.The convening of the International Internet Conference in Wuzhen,Zhejiang Province indicates that the level of Internet technology in China has been recognized by the world.The country puts forward the"Internet +" development strategy,conforms to the historical trend,and strongly promotes the rapid development of China's highly informatized and intelligent society.The concept of "perceiving China" is deeply rooted in people's minds,which fully demonstrates the interconnection of things and things and the unprecedented impact on the material world brought about by the arrival of the era of interconnection of all things.IOT(Internet of Things)is the Internet of Things technology that we are familiar with.It uses advanced information technology equipment such as radio frequency identification(RFID),infrared sensors,and laser technology to pass through certain physical communication rules to bring the world we are familiar with.The combination of Internet technologies and interactive communication and information enable us to monitor perception and control in real time and predict our world.The Internet of Things technology has been widely used in environmental monitoring,agriculture,logistics,security,industrial,medical,transportation and other fields.We know that in the field of environmental monitoring,in the past,in order to monitor and analyze the environment,some traditional methods were basically used.For example,first,we went to the pollution source to obtain a sewage sample,and then brought it back to the laboratory for chemical analysis.Compare with the standards of the country and related environmental agencies,and finally give some judgment conclusions.This dissertation develops a GPRS wireless communication module and data processing and dynamic display method that can be used for water quality COD(Chemical Oxygen Demand)online monitoring.Making full use of the advanced technologies of the modern Internet,the traditional method of environmental monitoring has been improved.Using distributed sensing methods,the data detected by the sensor probes scattered at different monitoring points is sent to the host through the GPRS wireless communication module.The software developed by us is used for centralized data processing.Finally,the monitored environmental pollution indicators are dynamically displayed online in real time through self-developed interface programs.Compared with the traditional method,it has multiple advantages such as real-time,convenience,and environmental protection.It is a field and direction that we are vigorously researching.
