The core of a smart city is to use a new generation of information technology to change the way in which city managers and occupants interact with each other in a smarter way to increase the clarity, efficiency, flexibility, and responsiveness of interaction. On the whole, it should have at least three layers: the perception layer, the interconnection layer, and the application layer.
Smart City Key Technologies
Collecting all-round city information through the perception layer, linking information systems through the interconnection layer to interact and share information, and using in-depth application of intelligent technology to analyze collected data to obtain more novel, systematic and comprehensive information. Insights to solve specific problems. From a technical point of view, the following basic technologies are the necessary cornerstones for a smart city.
Perception technology here is a broader concept. Specifically, it refers to a wider range of devices or systems that sense, measure, collect, and transmit information. By using these devices, any information, such as indoor temperature, humidity, smoke, road vehicle information, and urban traffic conditions, can be quickly acquired and analyzed for immediate response and long-term planning. As a most intuitive way of perception, video is widely used in cities. We believe that in the current and future city applications, the development direction of video application solutions is diversified and high-definition, with both analog HD video application solutions for social resources and IP network high-definition video for real-time business parts. The application plan also includes HD-SDI lossless high-definition video applications for deployment in the city's key control points.
Smarter technology “more in-depth intelligence†is another feature and requirement of a smart city. Intelligence refers to the in-depth analysis of collected data to obtain more novel, systematic, and comprehensive insights to solve specific problems. This requires the use of advanced technologies to handle complex data analysis, aggregation, and calculations in order to integrate and analyze vast amounts of cross-regional, cross-industry data and information.
Video intelligent technology has developed into today and has gone through several stages. Intelligent technology can be divided into several major categories: video behavior analysis, license plate recognition, video diagnosis, intelligent retrieval, number statistics, image restoration, and face recognition. The amount of video and image data is very large. It contains a lot of trending, empirical and ambiguous information. The potential of video intelligence is enormous.
Interconnection - The "more comprehensive interconnection and interconnection" of embedded technology is another basic feature and requirement of smart cities. Here, interoperability refers to the connection and sharing of dispersed information and data collected and stored by various “perceived†devices throughout the city to interact and share with each other so as to better monitor the environment and business conditions in real time. From the perspective of analyzing the situation and solving problems in real time, the work and tasks can be accomplished remotely through multi-cooperation, thus completely changing the way the world operates.
To realize “more comprehensive interconnection and interoperability†means that a large amount of computing resources will be embedded in various types of equipment in a small-scale and distributed manner, thus forming various kinds of mobile and interconnection technologies capable of acquisition, calculation, and transmission. Terminal equipment, these equipments then transmit the collected data to the back end through the transmission network.
In this process, we see that embedded devices developed using embedded technologies can meet the technical requirements of miniaturization, multi-functionalization, and low power consumption. Using embedded NVRs, DVRs, car DVRs, PVRs, and other equipment as the underlying access gateway for the entire system, completes all types of on-site analog HD video, network HD video, SDI HD video, various video and temperature data, smoke, alarms, and more. Collect, analyze, and upload the collected information of the sensor to realize the interconnection of the data in the sensory layer of the “Smart Cityâ€.
Solutions for "Smart City" solutions
The management objectives of smart city security can be clearly defined as the management of people, vehicles, and objects. The level and direction of management can also be divided into three phases. The first is the establishment of a city-level video surveillance alarm platform, whose core is security. The second level is the construction of the city’s emergency communications command. Its core is prevention and response. The third level is the city of things, digital cities, and smart cities. Its core is to serve people.
The construction of smart cities mainly includes the following aspects: vehicles, roads, important places, energy, and law enforcement.
The focus of urban vehicle management includes urban public transport vehicles, rental vehicles, long-distance transport vehicles, monitoring of their operational status, real-time location information, and through the collection and analysis of information data, to achieve scheduling, emergency command and other functions. The vehicle management can realize the data acquisition and position information collection of the vehicle running status, and the environmental data records of the inside and outside of the vehicle when the vehicle is running. The data is uploaded to the integrated management platform for data analysis, and these data can be used for analysis of urban road conditions, urban public traffic scheduling, and response to major emergencies.
Urban road management vehicles are not merely means of transport in the city. Urban life can not be separated from vehicles. It is an important part of carrying people's urban life. Whether it is from the perspective of urban management, public service or public safety, it is very necessary to collect data from urban vehicles, and then perform data mining, analysis and application accordingly. The "Smart City" put forward higher requirements for the collection and application of vehicle information.
Pavement control station uses cameras, microwaves and various sensor technologies to realize statistics of people flow, traffic flow and vehicle type through HD video intelligent analysis technology. At the same time, it collects various road comprehensive information and issues various control signals, charging according to different rates in different time periods. , Get real-time traffic flow, learn about vehicle violations.
The use of various models and algorithms of intelligent transportation can provide timely and accurate traffic information for the traffic management department and personnel, so that the traffic management control system can effectively adapt to various traffic conditions, and at a relatively macro level, it can rationally groom or deploy the capacity.
The model algorithm can also provide various traffic information for managers and travelers at any time, helping road users to reasonably select driving routes, avoiding traffic congestion, and reducing traffic accidents, thereby greatly enhancing the effective use potential and accessibility of road network systems. The ability to improve the mobility, convenience, safety, and comfort of the entire transportation system increases the transportation efficiency and economic efficiency of the entire transportation system, and at the same time reduces the negative impact of the transportation system on the environment.
The management of video images in important urban areas provides the intuitive state and environmental information of important buildings and urban core equipment. It is the most important means of information acquisition and monitoring methods; it can generate trends through intelligent analysis of video related to important buildings and urban core equipment. Early warning, such as intrusion detection alarms for various prohibited areas, detection of suspicious persons around the building, and personnel gathering detection. When the video intelligent analysis results exceed the alert value, relevant alarm information can be triggered to the monitoring center to remind the relevant personnel. Processing can also be reported to the relevant department for early warning.
Through the use of integrated sensing devices, sensor sensing information of buildings can be aggregated, such as vibration sensing, temperature sensing, smoke sensing, etc. After all types of sensing information are triggered, they can be aggregated and comprehensively related information is reported to the monitoring center. For example, the video images around the alarm point are called out to notify the entrance and exit management system, and the upper management system is reported to block the traffic intersections around the building, etc.; by recording the personnel's on-duty monitoring information, it is ensured that the key protective equipment and buildings are under supervision at any time. To avoid the management and monitoring of vulnerabilities.
Urban energy management aims at the monitoring of oil storage and gas storage stations, monitoring of refueling and filling stations, and dangerous goods vehicles, and realizes intelligent control of entrances and exits, such as the linkage of license plate recognition results and RFID vehicle access management. In emergencies, emergency control under the linkage of alarms at entrances and exits, forced closure or opening of certain entrances and exits, and procedures for emergency procedures; trend warnings generated by video intelligent analysis, such as intrusion detection. Sensor sensing information, such as temperature information, pressure information, static electricity alarm information.
The traditional fixed-point deployment of urban mobile law enforcement management is often limited to local physical locations, while urban people, vehicles, and goods are constantly moving, and the demand for public security is also more complicated. Only a fixed-point distribution control often fails. To achieve full coverage, it is necessary to meet the diverse public safety needs of the city through more flexible deployment methods.
The mobile vehicle enforcement system and the individual law enforcement system are effective supplements to fixed points. In addition, through such portable mobile devices, it is also possible to more intuitively understand the deployment of police forces in the city, and to respond to police strategies and emergency response strategies. Other top applications provide better data support.
Conclusion
The “Smart City†application solution aims to understand urban emergencies in a more timely manner through more “intelligent†perceptions, deploy resources more instantly to respond, and better monitor and prevent crimes through the use of intelligence. Technical analysis data better services for upper business applications. A smart city will be the general trend of the entire world. This requires the joint participation and cooperation of every company and everybody. We need to draw a blueprint together, show their strengths, and keep making progress and innovation.
