| Since the COVID-19 outbreak,public health issues have gradually become the focus of attention in the post-pandemic era.Especially in terms of disinfection and sterilization,there are still some problems with traditional manual killing or ordinary machine killing on the issue of how to perform efficient disinfection and supervision in public places.With the rise of the Internet of Things,the combination of intelligent disinfection equipment and the IoT supervision platform can solve this problem.Based on this,this thesis has developed a public health disinfection supervision system.This thesis summarizes the development of public health,the research of the IoT platform and the development of the public health disinfection supervision system at home and abroad.At the same time,based on the combination of IoT technology and traditional chemical process disciplines,the public health disinfection supervision system includes a set of low-cost IoT sterilization and deodorization equipment,and a cloud platform that supports real-time data reporting and storage,equipment management,user management,and data display.It will be applied to two scenes of garbage station and public toilet.The main work of the thesis is to design unique intelligent disinfection equipment at the detection layer for the two scenes of garbage station and toilet respectively,and to design and implement the framework design of data center and supervision platform at the application layer.Among them,at the detection layer,intelligent devices with simple structures are designed for the two scenes of garbage station and public toilet,which are based on ozone technology to achieve real-time and thorough sterilization and deodorization.In addition,the device can obtain data such ashe status of the garbage can and the overflow of the garbage can in garbage station or the water consumption and the number of users in the toilet through a single sensor at low cost.The data center platform is used to receive the data reported by massive IoT devices.For massive data storage,automatic table creation and shard storage are adopted to optimize data storage and query.At the same time,Redis cache is used to optimize the online status of the device,online number and other functions,presents a unique optimization algorithm to achieve high-performance,low-memory programs.The management platform is used for the management of IoT devices,user management,and provides related interfaces to realize data visualization.The entire supervision platform is compatible with disinfection equipment in different types of places,and meets the diversified supervision needs of different users through Web and WeChat applets.Finally,this thesis introduces the actual application of the public health disinfection supervision system in many actual pilot garbage stations and public toilets,and conducts a performance stress test on the platform of supervision system to verify the functions of each module of the system.Practical applications show that the disinfection equipment has a good effect of sterilization and deodorization,the platform of supervision system is operating normally,meeting user requirements,indicating that the development tasks are basically completed.At the end of the thesis,the research work during this period is summarized and prospected. |
