Design Proposal And Analysis Of Municipal Internet Of Things

In this thesis, the state-of-the-art Internet of Things, cloud computing and other advanced technology, design and build a complete set of municipal infrastructure intelligent management platform, improve the park intelligent system, the digital municipal platform for the preliminary design. Platform for enterprises in the region to provide more convenient and more efficient, high level of service components include support subsystem and application subsystems.Support subsystem includes cloud computing platform and ZigBee-based communications network, application subsystem includes GIS platform, intelligent street light management system, covers anti-theft alarm system, integrated trench monitoring system, flood control and water level forecasting system, the automatic the seedlings irrigation system, temporary pipeline management system, subsystem of the ZigBee positioning system, drains monitoring system.Support subsystem, the Internet of Things application-oriented data network as the center, mainly to complete the information perception, data processing, data backhaul, as well as decision support and other functions, the hardware platform consists of sensor network, the core bearer network and information services system several parts, with the help of cloud computing SaaS, PaaS, IaaS and other state-of-the-art business model of computing power distributed to the end user.Application subsystem, based on open geospatial information resource sharing service platform, intelligent street light management system that covers anti-theft alarm system, such as the eight systems integration in a unified platform.(1) intelligent street light management system, as the Internet of Things technology in the lamp industry, intelligent lighting control and centralized management; timely, real-time master the system operating conditions; rational use of energy resources, to achieve on-demand lighting, put an end to waste; equipment automatic fault reporting and24-hour real-time anti-theft cable.(2) covers anti-theft alarm system testing covers the opening and closing state judge covers and ditch the well (wire) cable will be damaged and Pirates of the loss.(3) Combined duct monitoring system by monitoring equipment to pipe water pressure, temperature and other parameters information in real-time collection and monitoring, and through the ZigBee network to upload data to the monitoring center, to form a data file. When the monitoring system detects changes in water pressure, temperature, humidity, gas and other parameters beyond the scope of the set value, the system will automatically alarm.(4) flood control and water level forecasting system, an important area in the flood control area, the locations of water level monitoring points, the on-site water level data reported to the monitoring server through ZigBee wireless data collection terminal unit (DCU) in accordance with a fixed time interval. System software based on the data reported by the formation of water level change curve. When the water level exceeds the set value, the system sends an alarm signal to judge the level of the accident at the same time, start the appropriate accident linkage mechanism.(5) automatic seedling irrigation system, automatic irrigation system seedlings through the scene sensor timing acquisition related to plant water requirements meteorological parameters amount ZigBee-based communications network feedback to the background the main station, so that the background master historical data summarizes the various meteorological parameters of history curve for better prediction and decision-making.(6) the ZigBee positioning system not only to achieve the registration of public facilities, sorting, archiving function, but also with tracking, positioning, status inquiries and other functions.(7) the drains monitoring system established in the key node of the drains monitoring points to be monitored, sludge height, water quality related parameters of the scene, as well as traffic data by the ZigBee wireless data collection terminal unit (DCU) according to a fixed time interval be reported to the monitoring server. The municipal Internet of Things design make full use of various information resources, the establishment of various types of data repository, providing analysis and support the macro decision-making of the various departments in the region to ensure the accuracy and objectivity of the decision-making, in a timely manner. At the same time, the system provides a good data exchange interface to lay a good foundation for future system upgrade, be able to significantly reduce water, electricity and other energy costs through effective management of expenses and accident costs incurred.
