Some countries and regions have begun to study countermeasures for low-carbon transportation, for example, detailed classification management of vehicles with different emission standards, and the use of scientific and technological means and taxation systems to control carbon emissions. Countries and regions such as the United Kingdom, Sweden, Germany, Italy, Norway in Europe, Singapore, Tokyo, Taiwan, Hong Kong, and Australia in Asia have established low-carbon traffic zones, low-emission zones, green traffic zones, and clean demonstration zones. The regional air quality is guaranteed, and the use of clean transportation is encouraged.
RFID (Radio Frequency Identification) technology is an automatic identification technology that originated in the 1950s. RFID technology has broad application prospects. Intelligent transportation, logistics and warehousing, retail, manufacturing, medical and other fields are all RFID applications.
The development of low-carbon transportation is the general trend. The use of RFID technology and the development of electronic environmental labeling systems are used to classify and control cars according to different emission standards. On this basis, the establishment of low-carbon transportation zones is inevitable in the current domestic “perceived China” environment. choose.
Through the construction of low-carbon traffic zones, an urban traffic pattern in which “high-polluting yellow-label vehicles are prohibited, ordinary emission vehicles are restricted or toll-free, and zero-emission vehicles are free to pass” will be formed in the city, which will promote the elimination of highly polluting vehicles and encourage The use of low-carbon emissions such as hybrid electric vehicles, especially zero-carbon pure electric vehicles and other new energy vehicles play a role in promoting, and at the same time can effectively resolve the problem of urban congestion, and truly achieve low-carbon transportation, energy conservation, emission reduction, and improvement The purpose of air quality.
Through the establishment of low-carbon transportation and tourism areas and low-emission demonstration areas, pollutants emitted by vehicles in a certain area are basically eliminated, and the air quality level of the urban environment is improved, especially the air quality around the road. Through demonstration projects, more citizens can be encouraged to purchase and use new energy vehicles and low-emission vehicles, reduce the harm caused by exhaust gas pollution, and protect the ecological environment.
The low-carbon traffic zone system is mainly composed of four parts: environmental protection electronic signs, vehicle sensing base stations, environmental monitoring base stations, and supervisory control platforms.
Electronic environmental protection mark. The 900M RFID electronic sign is adopted, which contains vehicle information such as license plate number, vehicle model, emission standards, and has a unique identification code, which replaces the original conventional paper environmental protection signs, and forms a unique correspondence with the car.
Vehicle sensing base station. Using dual-base identification technology (ie video + radio frequency), the non-contact automatic identification of electronic tags can be realized through radio frequency identification, which can detect electronic signs on high-speed vehicles (180km/h) at a long distance (up to about 15m) And read and write; realize license plate recognition, take photos and obtain evidence through video recognition, and can match the result of radio frequency identification.
Environmental monitoring base station. Established on both sides of the road, it can detect and warn the motor vehicle pollution of the urban road network in real time.
Regulatory control platform. It is the brain of the low-carbon traffic zone system, responsible for intelligent analysis of the transmitted identification information and environmental information, and coordinated with the environmental protection and public security business processing platform to realize the analysis and processing of the low-carbon traffic zone supervision business.
The application of RFID in low-carbon transportation construction includes the following parts:
1) Applied in the construction of green intelligent transportation system to achieve a win-win situation for congestion control and pollution control
Congestion and pollution coexist, the more congestion, the more serious the pollution, and the greater the harm to people.
Under normal circumstances, the exhaust emissions of a vehicle when driving at a speed of 20km/h is more than double that of 40km/h. Use electronic environmental protection signs as the carrier, use Internet of Things technology to establish an intelligent transportation system, collect, organize, and analyze comprehensive traffic information, and conduct traffic control based on road congestion conditions, so that the traffic flow on the road network is in the best state, thereby improving Traffic congestion reduces motor vehicle pollution. According to estimates, it can reduce vehicle pollutant emissions by 15%-20%.
2) Applied to public transportation priority system
Electronic environmental protection labels can meet the needs of automatic signal collection, and serve for the development of public transportation, adhere to the strategy of public transportation priority, construction of dedicated public roads and public transportation priority signal systems. By increasing the speed of public transportation, a rapid transit system is formed, thereby increasing the bus travel rate, reducing the travel ratio of private cars, and reducing exhaust emissions.
3) Applied in law enforcement of high-pollution yellow label vehicles and non-standard vehicles
High-polluting yellow-label vehicles refer to motor vehicles that do not meet the national I emission standards, and non-standard vehicles refer to vehicles that have not received the environmental protection annual inspection or fail the environmental protection annual inspection. Although yellow-label vehicles and non-standard vehicles only account for 10%-15% of the city’s total motor vehicles, they emit 50% of the total emissions of motor vehicles. The regional traffic restriction system established by the use of electronic environmental protection signs and Internet of Things technology can realize the networking of the motor vehicle information system, the environmental protection supervision system and the road traffic system, so as to realize the uniqueness of vehicle sign recognition and judgment, and improve the accuracy and control of traffic restriction management. High efficiency.
4) Applied to the traffic control of vehicles with different emission standards
Pilot congestion charging policies and establish low-carbon traffic zones. That is, on the basis of setting restricted areas for yellow-label vehicles and non-standard vehicles, establish a low-carbon transportation zone that only allows free passage of new energy vehicles, pure electric vehicles, and vehicles above National V, and other vehicles from National I to National IV. According to different emission levels, toll and pass are classified.
5) It is applied to environmental protection inspection of motor vehicle license plate, annual inspection and road inspection
The use of electronic environmental protection signs can effectively realize the online audit control of environmental protection writing and public security reading of motor vehicle license management, ensuring 100% environmental protection compliance of licensed vehicles; it can effectively prevent cheating such as annual exhaust gas inspection and vehicle replacement detection; it can realize road inspection law enforcement officers to hand-held mobile The law enforcement terminal has the functions of remotely querying vehicle information, and investigating and punishing yellow-label vehicles, unlabeled vehicles, vehicles with invalid marks, forged and altered vehicles on the spot.
6) Applied to the online control system of traffic pollution intelligent monitoring
Establish a monitoring system for environmental air and motor vehicle pollution on both sides of the road, real-time detection and early warning of motor vehicle pollution in the urban road network, combined with intelligent transportation systems, and use of electronic environmental protection signs to implement intelligent control of vehicle traffic.
7) Apply to the guarantee of the national joint prevention and control mechanism for motor vehicle pollution
The existing paper signs rely entirely on manual law enforcement, and are checked by public security traffic police and environmental protection personnel. The law enforcement cost is high, the efficiency is low, and the enforcement is difficult. An electronic environmental protection sign system with unified standards and content has been established. An instrument or a handheld PDA (Environmental Protection Communication, Policing Communication) can realize mutual recognition of signs between cities, and truly achieve the purpose of joint prevention and control.
8) Information sharing applied to other government departments
Through the development of multi-departmental information integration platforms such as environmental protection, public security, transportation, and urban construction, the rapid sharing of electronic sign information is realized, and the city’s comprehensive management of vehicles, such as compulsory traffic insurance, automatic toll counting, etc., is realized.
