Design And Implementation Of Water Quality Monitoring Unit In Swimming Pool Based On MSP 430

Background: As one of the most popular sports today,swimming is one of the most important.Under the background of the rapid development of science and technology,intelligent swimming pool is an important means to ensure water quality safety through scientific and technological means;The existing pool water quality monitoring equipment in the market can achieve a certain degree of intelligence,but most of them are used in the near swimming pools and the cost of installation is higher.The relatively old low-end swimming pools need a low-cost upgrade on existing equipment.Product.Objective: To provide a design product for some swimming pools based on the existing water quality treatment equipment.Methods: Firstly,the research background and pre-investigation were analyzed to find out the existing problems in the water quality management of the existing swimming pool and to clarify the pertinence of the design.2,the use of MSP 430 as the main control chip,combined with sensors and other components,to achieve real-time water quality management and remote monitoring functions;3)Based on the actual situation and requirements analysis,the overall design plan is constructed and the hardware circuit design is completed.Its functional circuits include: real-time monitoring of five indicators of pool temperature,water level,pH,residual chlorine,turbidity,control of existing equipment,and remote monitoring of mobile phones.At the same time,according to the overall design scheme,complete the system software design.Software design functions include: data collection,data analysis and processing,data output and command control.In the end,the system is divided and the whole debugging is carried out.According to the results of multiple debugging,the optimization analysis is carried out and the design is completed.The results show that this design basically realizes all the expected functions,and the finished product can achieve field and remote water quality management functions.Conclusion:1,pre-survey found that most of the middle and low-end swimming pools have unreasonable timing of water quality measurement,low equipment management efficiency,low level of automation and waste of resources.2,The middle and low end pool operators need an affordable intelligent water quality monitoring unit to integrate the existing equipment and upgrade the pool water quality management at a lower cost.3,This design is based on the monitoring requirements of the water quality of the swimming pool.Through the MSP 430 as the main control chip,relevant sensor circuits,relay circuits,and communication circuits are added.It can realize real-time monitoring function of water quality,control function of existing equipment and communication function of lower machine and mobile phone.4,according to the need of debugging,the author uses a simulated swimming pool to adjust the hardware and software of the design.The results show that the design can achieve real-time monitoring of water quality information,automatic control equipment,enforcement of managers 'instructions,and remote monitoring functions on the mobile phone.
