[Abstract]:This paper uses advanced technologies such as Internet of things, cloud computing and other advanced technologies to design and build a complete set of intelligent management platform for municipal infrastructure. Through the improvement of the intelligent system of the park, a preliminary design of the digital municipal platform is carried out. The platform can provide more agile, more efficient and high level services for the enterprises in the region, and the components include the branch. Support subsystem and application subsystem.
The supporting subsystem includes the cloud computing platform, the ZigBee basic communication network, the application subsystem including the GIS platform, the intelligent street lamp management system, the well cover anti-theft alarm system, the integrated pipe trench monitoring system, the flood control water level measuring and reporting system, the automatic seedling irrigation system, the temporary pipeline management system, the ZigBee positioning system and the drainage pipeline monitoring system and other subsystems.
The support subsystem, centered on the application oriented Internet of things data network, mainly completes the functions of information perception, data processing, data return, and decision support. The hardware platform consists of several large parts, such as sensor network, core bearing network and information service system, and the advanced business models such as cloud computing Iaas, PaaSS, SaaS and other advanced business models. Large computing power is distributed to end users.
The application subsystem, based on the open geographic spatial information resource sharing service platform, integrates the eight systems of intelligent street lamp management system, well cover anti-theft alarm system in the unified platform. (1) the intelligent street lamp management system, as the application of the Internet of things technology in the street lamp industry, realizes the intelligent monitoring and centralized management of the lighting facilities. Timely and real-time control of the operating conditions of the system; rational use of energy resources to realize on-demand lighting and eliminate waste; at the same time, the automatic reporting of equipment failures and the 24 hours of the cable will be realized in real time. (2) the wellhead burglar alarm system determines whether the electric (line) cable in the well cover and in the ditch will be damaged by detecting the opening and closing of the well cover. (3) the monitoring system can collect and monitor the water pressure, temperature and other parameters in the pipeline through monitoring equipment, and upload the data to the monitoring center through the ZigBee network and form the data files. When the monitoring system detects the water pressure, temperature, humidity, gas and other parameters, the system is beyond the set value. (4) the monitoring and reporting system of flood control water level, the water level monitoring point is set in the important section of the flood control area, the water level data of the field is reported to the monitoring server by the ZigBee wireless data acquisition terminal unit (DCU) according to the fixed time interval. The system software is based on the reported data to form the water level change curve. When the water level is beyond the water level, the water level exceeds the water level. After setting the value, the system sends out the alarm signal, at the same time to judge the accident grade and start the corresponding accident linkage mechanism. (5) the automatic seedling irrigation system, the automatic seedling irrigation system collects the meteorological parameters related to the plant water through the sensor of the site, and feedback to the main station through the ZigBee basic communication network, so that the backstage main station is connected. Through historical data, the historical curves of the meteorological parameters are summed up for better prediction and decision. (6) ZigBee positioning system not only realizes the registration, arrangement and filing function of public equipment, but also has the functions of tracking, positioning, and state inquiry. (7) the monitoring system of drainage pipeline is set up to monitor the key nodes of the drainage pipeline. The data of the site's silt height, water quality parameters and flow data are reported to the monitoring server by the ZigBee wireless data acquisition terminal unit (DCU) at a fixed time interval.
The design scheme of the municipal Internet of things makes full use of all kinds of information resources and sets up various data repositories to provide analysis and support for the macro decision of various departments in the region, and to ensure the accuracy, objectivity and timeliness of the decision-making. At the same time, the system provides a good data exchange interface, which lays a good foundation for the upgrading of the system in the future and is effective. The management can greatly reduce the expenditure of water, electricity and other energy costs and the cost of accidents.
