"Digital city management" is a new mode of urban management formed to change the current state of extensive management of most domestic cities, improve the level of urban management, and apply modern information technology to urban management. The new digital urban management model effectively solves some of the difficulties and problems in urban management. Through the division of the city ’s 10,000-meter unit grid, the city ’s components and events are managed, and the city management is refined, refined, and implemented to achieve a variety of cities. Quick discovery, precise positioning, timely handling and effective supervision of management problems. Application requirements of RFID technology in digital urban management At present, the location of component events in digital urban management is currently mainly inspected by urban management inspectors using PDAs to manually inspect various components and events in the 10,000-meter grid, and can use PDA cameras combined with GPS positioning for on-site collection and reporting. The accuracy of the logo is subject to artificial Greater impact. The city management is all-encompassing, in addition to the city appearance and environmental sanitation, it monitors and supervises the important municipal transportation facilities, gas pipelines, water supply and drainage facilities and water quality related to the safe operation of the city, builds a city disaster reduction information system, establishes an emergency linkage command system, and establishes an orientation The urban management and government service system and so on are all the contents of the further construction of digital urban management. In the process of further construction and development of digital urban management, how to accurately identify monitoring objects and how to solve the data collection and transmission under special circumstances are the end and key data source of the digital urban management monitoring network, and RFID technology is the latest solution to these problems. RFID (Radio Frequency Identification) technology is also known as electronic tag technology, which is a specific application of radio technology in the field of automatic device identification. The electronic tag realizes two-way communication in a non-contact mode through wireless radio frequency signals, completes automatic identification of target objects and read and write operations of related data, and has the advantages of non-contact, high precision, anti-interference, fast operation and strong environmental adaptability. The electronic tag has a globally unique identification code, which can uniquely represent the object itself, and is the key connecting the real physical world and the virtual information world. Electronic tags are divided into two categories: passive and active. Active tags have their own power supply. The use of wireless transmission technology can complete long-distance communication identification in the range of several meters to hundreds of meters or even thousands of kilometers. Its battery power supply and service life are also It can last up to several years. Using these technical features of RFID, combined with the management of corresponding information systems, can greatly enhance the role of digital urban management, better realize the management of urban components, and facilitate event processing. Bridge tunnel monitoring Through the digital urban management online monitoring system platform, the main information of bridges and tunnels can be located, displayed and warned, and the structural safety status (including vibration, deflection, stress, displacement, cracks, etc.) of large bridges, viaducts, interchanges, tunnels and other facilities Environmental conditions (wind, temperature, illuminance, etc.) information, as well as real-time query statistics and positioning display of comprehensive evaluation data of working status, to achieve the electronic, standardized and scientific management of bridge tunnels, so that the regulatory department can accurately and reasonably grasp the bridge tunnel Health status ", saving manpower and other resources. On the basis of traditional sensors, combined with active electronic tags, sensor information can be sent to the data collection system through active electronic tags, which effectively solves the problems of sensor installation and data collection. Flood prevention online monitoring The flood control decision-making and command system is an important part of the digital city management system. It mainly realizes real-time monitoring of the water level data of the main rivers in the urban area, the integration of meteorological information, the reporting and management of disasters, and the realization of the city through the portal website and office automation system. Internal management of flood control and public services. Due to the different environments of flood control monitoring points, including river monitoring points, sluice detection stations, pumping stations, and low-lying water-storage area detection points, etc., the necessary conditions for the deployment of information systems such as power supplies or networks are lacking. Through the active electronic tag, a local wireless real-time data collection network system can be constructed to realize real-time communication with the flood control decision-making command system, and the accurate information automatically detected by the sensor can be displayed in layers on the geographic information system, and the alarm and product can be exceeded. Water forecast, flood and other information release. Online monitoring of urban sewage Water pollution is a very serious environmental problem facing China and the world. As a city supervision department, the city management office is of great significance to do a good job in the supervision of urban sewage. The urban sewage online monitoring system is mainly to supervise and manage the operation and monitoring of the sewage monitoring objects. Its business mainly includes data collection, data analysis, industry supervision, basic data maintenance and other functions. Similar to flood control monitoring, the combination of sewage monitoring sensors with active electronic tags can construct a flexible wireless data collection system that collects sewage sensor data in real time and displays and monitors them in the digital urban management system. Dangerous goods tracking and management The electronic tag-based dangerous goods safety management and logistics tracking system will use electronic tag technology to implement identification and use of dangerous goods and record the inspection information, and combine with the logistics management system to realize the delivery, inspection, use and sale of dangerous goods Full process control of the entire process. The entire dangerous goods management system includes three parts, namely the dangerous goods manufacturer system, the dangerous goods sales system and the dangerous goods inspection station system. Parking management This system mainly uses electronic tags to identify and track each approaching vehicle, and also can accurately monitor and manage each parking space. Through the monitoring of all aspects of vehicle entry and exit, the scheduling and management of vehicle berths, as well as the parking lot patrol management, etc. can be achieved. In each link, the vehicle berth management system can be used to understand the vehicle berth arrangement. Using electronic tags, the computer management system can implement scientific and standardized management of each parking lot, strengthen effective monitoring of all links in the parking lot, improve the effective use of parking lot resources, and realize the unified management and sharing of various data resources. Dog management The management of pets such as dogs in cities is a complex task that concerns the health and safety of the people and the direct interests of dog owners. The dog management system uses electronic tags to effectively manage dogs and other pets, and issues RFID tags (electronic dog tags) for each dog to realize the intelligent, networked, and digitized management of dogs, and to achieve administrative law enforcement, health and epidemic prevention. Network management and data sharing of relevant departments of management, establish a canine RFID inspection and supervision system. In the "Electronic Dog Tag", various information such as the owner's name, address, dog's name, type of dog, dog's photo, dog's immunization status, and annual dog inspection are stored in the "Electronic Dog Tag" Law enforcement personnel can easily check the "electronic dog tags" worn by dogs at long distances through handheld readers based on PDA handheld computers, and manage dogs efficiently, while also solving the problems of counterfeit and replacement of dog tags. summary From the perspective of application methods, the current application of electronic tags in digital urban management can be divided into two major categories. One type uses the unique identification function of electronic tags and combines information management systems to complete the monitoring and management of items, such as vehicles, dogs, Automatic tracking and identification management of dangerous goods, etc .; another type of combination of active electronic tag recognition and wireless communication technology and modern sensing technology can realize various types of monitoring, such as monitoring of bridges, tunnels, water levels, pollution, etc. Solve the difficult problem of sensor data collection and deployment. Due to the adoption of RFID technology, the effectiveness and timeliness of digital city management have greatly increased. At the same time, with the maturity and development of electronic tag technology, its application prospects in digital city management will be more extensive and deeper.
