Design Of Water Environment Monitoring System Of Huangshui River In Xining City Based On MSP430

With the rapid development of the economy and society,while the amount of industrial and domestic water has been increasing along with the excessive exploitation and utilization of resources,the phenomenon of water pollution has become increasingly serious,and the problems of ecological environmental protection and governance have become increasingly prominent.Located in Xining City,Qinghai Province,Huangshui river as a water source guarantees industrial and agricultural water use in this region.Whether the water quality is good directly affects the economic and social development of this area.How to monitor the water quality change efficiently,real-time and conveniently has become an important content of scientific and technological work and scholars' research.Traditional water quality monitoring often uses manual field sampling or wire transmission,which requires a lot of manpower and material resources,and cannot achieve the desired results.This paper designs an intelligent water quality monitoring system based on MSP430,which mainly includes:(1)The system consists of MSP430 control circuit,power supply system,signal acquisition circuit,GPRS module,LCD display module,RS232 module,Lab VIEW module and APP module.(2)The interface circuit diagram of each module is designed.The sensor is used to collect the information of water quality factors such as pH value,turbidity,water temperature,water velocity and image,which is processed by MSP430 microprocessor,and the monitoring results are output through the upper computer Lab VIEW and the mobile phone APP terminal.(3)Design a dual power supply system which combines solar panels and dry batteries.SD card storage module is used to save the collected data in real time,and GPRS(SIM900A)wireless communication module is used to transmit the collected data.MSP430 main control chip controls GPRS module by command,and sends data to user's mobile terminal at a certain time interval to realize remote real-time monitoring.The simulation test of hardware and software is completed in the laboratory.The design of the system has a certain reference value for further realizing real-time and convenient water quality information monitoring.
