Research And Design Of Manhole Cover Management And Control System In Smart City

Under the background of "all things connected",the development of the city is becoming more and more modern,which requires more and more refined management of urban infrastructure.As the core part of infrastructure,urban well cover has a large audience and wide distribution.However,due to the lack of efficient and intelligent unified management and control system,various kinds of safety accidents have occurred frequently in recent years.The design of an efficient remote well cover real-time management and control system and the fine management of well cover and corresponding facilities is an important part of promoting the intelligent management of infrastructure and building a smart city.This paper designs and constructs a complete closed-loop intelligent management and control system of the Internet of things.This paper constructs a complete closed-loop intelligent management and control system of urban road well cover.In the part of terminal data acquisition,by optimizing the structure of sensor circuit,the type of well cover information acquisition is added.The collected node information data is transmitted to the server through Lora(wide area Internet of things narrowband Technology)protocol in a low-power long-distance working mode.The server side completes the visualization of the collected data and provides rich control functions on the user's operation interface.Finally,the historical data of road well cover is analyzed and mined,the abnormal cycle frequency and alarm type of well cover are predicted by using multiple linear regression model,the maintenance and inspection cycle strategy of well cover is formulated,and the intelligent and refined management of urban road well cover is realized.The node information collected by the terminal includes displacement of well cover,inclination angle and underground liquid level information.In the traditional sensor working mode,considering the power consumption of the actual well cover equipment,antenna matching,data transmission and other work issues.In this paper,the interrupt request mode of the trigger,the peripheral matching circuit,and the new host module networking mode are redesigned.The backend of the system platform is built based on the SSM(spring spring MVC MyBatis)framework,and the redis cache is introduced into the persistence layer.The front-end uses JavaScript as the development basis,and various visual plug-ins such as Eckarts and EasyUI are used to enrich the data display and improve the user experience.Finally,the significance of the multiple linear regression model is verified,the terminal precision of the system is tested and the platform function is realized.The practicability of the system has reached the expectation,which can provide efficient and intelligent well cover management and control,and has a wide range of application scenarios.
