Research And Design Of Intelligent Control System For Water Use In Campus

With the continuous consumption of water resources,how to save water resources becomes an important research direction.As a great educational power,our country has a large number of campuses,and the campus water has its unique law.It is of great significance to design a reasonable water system for the campus to realize the water-saving goal.Taking a university in the arid area of northwest China as an example,the paper studies the monitoring plan of water system,the control strategy formulating and the design of the engineering prototype based on the actual demand.(1)Firstly,considering the toilet flush and afforestation irrigation,two water controllable link,I determine the system network communication structure and the system organizational structure according to the actual layout of the network in the campus and the condition of water irrigation and through comparative analysis.Based on the current situation of campus water,the hardware framework of the flushing controller and the irrigation controller is further determined.The hardware design of the controller and the network communication module is completed by using the STM32F103.(2)Control strategies are designed for different water use to achieve the goal of water saving and moderate cleanliness or irrigation.In the scene of long slot toilet and pit toilet,the intelligent flushing strategy based on user usage habit is adopted to achieve the double goal of water saving and cleanliness.In the scene of afforestation irrigation,the dynamic strategy based on real-time humidity and optimizing irrigation period is adopted to prevent the problem of overirrigation and untimely irrigation.(3)On the basis of the above research,the process software realization of WIFI communication,433 communication and Bluetooth communication is analyzed and illustrated in detail in paper.In order to realize the field adjustment of controller parameters,the APP is designed by E4 A software.And the monitoring interface of campus water control system is developed based on Qt Creator.The results of debugging of PCB and function test of WIFI,Bluetooth,433,APP and monitoring system show that the circuit of each unit works normally,and the scheme is feasible in the paper.The results of comparative analysis of water saving effect of the control strategy adopted in the paper and the existing control mode show that the water consumption is not only less after adopting intelligent control strategy,but also ensures the cleanness and moderation of the toilet flushing and afforestationirrigation.
