In the next 20 years, the global temperature will increase by 0.2 degrees Celsius every ten years. Climate warming has become a problem that cannot be ignored and directly affects global production and life.
Some countries and regions have begun to study countermeasures for low-carbon transportation, such as refining the classification management of vehicles with different emission standards, and using technology and taxation systems to control carbon emissions. For example, Europe, the United Kingdom, Sweden, Germany, Italy, Norway, Asia, Singapore, Tokyo, Taiwan, Hong Kong, and Australia and other countries and regions through the establishment of low-carbon traffic areas, low-emission areas, green transportation areas, clean demonstration areas, etc. Regional air quality is guaranteed while using clean vehicles.
RFID (Radio Frequency IdenTIficaTIon) technology is an automatic identification technology that originated in the 1950s. RFID technology has broad application prospects, and intelligent transportation, logistics and warehousing, retail, manufacturing, medical and other fields are all applications of RFID.
Develop the trend of low-carbon transportation, use RFID technology, develop electronic environmental protection marking system, classify and control automobiles according to different emission standards, and establish a low-carbon transportation area on this basis, which is the inevitable current domestic “perceive China†environment select.
Through the construction of low-carbon traffic areas, the urban traffic pattern of “high-yield yellow-label vehicles banned, ordinary emission-restricted vehicles or toll-free traffic, zero-emission vehicles freely accessible†will be formed in the city, which will promote the elimination of highly polluting vehicles and encourage New energy vehicles such as oil-electric hybrid vehicles with low-carbon emissions, especially pure electric vehicles with zero carbon emissions, can also promote the urban congestion problem and truly achieve low-carbon transportation, energy conservation and emission reduction. The purpose of air quality.
Through the establishment of low-carbon transportation tourist areas and low-emission demonstration areas, vehicles will be eliminated from pollutants in certain areas, and urban environmental air quality levels will be improved, especially to improve the air quality around the roads. Through demonstration projects, more citizens can be encouraged to purchase and use new energy vehicles and low-emission vehicles to reduce the harm caused by tail gas pollution and protect the ecological environment.
The low-carbon traffic zone system is mainly composed of four parts: environmental protection electronic sign, vehicle-aware base station, environmental monitoring base station and supervisory control platform.
Electronic environmental protection mark. It adopts 900M RFID electronic sign, which contains vehicle information such as license plate number, car model and emission standard, and has a unique identification code to replace the original conventional paper environmental protection mark and form a unique correspondence with the car.
The vehicle senses the base station. Using dual-base identification technology (ie video + radio frequency), the non-contact automatic identification of electronic tags can be realized by radio frequency identification, and the electronic signs on vehicles with high-speed driving (180km/h) can be detected at a long distance (up to 15m) And reading and writing; through the video recognition to achieve license plate recognition, photo forensics, and can match the radio frequency identification results.
Environmental monitoring base station. Built on both sides of the road, it can detect and warn the motor vehicle pollution situation of the urban road network in real time.
Regulatory control platform. It is the brain of the low-carbon traffic area system. It is responsible for the intelligent analysis of the transmitted identification information and environmental information, and cooperates with the environmental protection and public security business processing platform to realize the analysis and processing of the low-carbon traffic area supervision business.
The application of RFID in low-carbon transportation construction includes the following parts:
1) Apply to the construction of green intelligent transportation system to achieve a win-win situation
Congestion and pollution are symbiotic, the more congested, the more serious the pollution, the greater the harm to people.
Normally, the exhaust emissions of vehicles traveling at 20km/h are more than double that of 40km/h. Taking the electronic environmental protection mark as the carrier, using the Internet of Things technology to establish an intelligent transportation system, collecting, organizing and analyzing the comprehensive traffic information, and conducting traffic control according to the road congestion condition, so that the traffic flow on the road network is in an optimal state, thereby improving Traffic congestion, reducing motor vehicle pollution. It is estimated that it can reduce motor vehicle pollutant emissions by 15%-20%.
2) Applied to bus priority access system
The electronic environmental label can meet the needs of automatic signal collection, and serve the development of public transportation, adhering to the bus priority strategy, building bus-specific roads and bus priority traffic signal system. By increasing the speed of public transportation, a rapid transit system is formed, thereby increasing the bus travel rate, reducing the proportion of private cars, and reducing emissions.
3) Applying to high-pollution yellow-label vehicles and non-standard vehicles
High-pollution yellow-label vehicles refer to vehicles with emission standards that do not meet the national I. No-standard vehicles refer to vehicles that fail to receive environmental protection marks without annual environmental protection inspection or environmental protection annual inspection. Although the yellow standard car and the standard car only account for 10%-15% of the total number of motor vehicles in the city, the pollutants emitted are up to 50% of the total vehicle emissions. The regional limit established by the electronic environmental protection mark and the Internet of Things technology. The system can realize the networking of the motor vehicle information system, the environmental protection supervision system and the road traffic system, thereby realizing the uniqueness of the vehicle sign recognition judgment and improving the accuracy and efficiency of the limit line management.
4) Traffic control for vehicles with different emission standards
Pilot the congestion charging policy and set up a low-carbon transportation zone. That is to say, on the basis of setting a restricted area for the yellow-label car and the non-standard car, a low-carbon traffic zone that allows only new energy vehicles, pure electric vehicles, and vehicles above the national V to pass freely, and other countries such as I-Country IV Class charges are classified according to different emission levels.
5) Environmental protection verification applied to motor vehicle licensing, annual inspection and road inspection
The use of electronic environmental protection signs can effectively realize the online auditing control of environmental protection writing and public security reading on the vehicle management, ensuring 100% environmental protection of the listed vehicles; it can effectively prevent cheating of the exhaust gas inspection and inspection; The law enforcement terminal, remotely inquires about vehicle information, and on-site investigates the functions of yellow-label vehicles, non-standard vehicles, marked-vehicle vehicles, counterfeit, and altered sign vehicles.
6) Applied to traffic pollution intelligent monitoring online control system
Establish an environmental air and motor vehicle pollution monitoring system on both sides of the road, detect and predict the motor vehicle pollution status of the urban road network in real time, and use the intelligent transportation system to use the electronic environmental protection sign information to implement intelligent regulation of vehicle traffic.
7) Application to the national motor vehicle pollution prevention and control joint control mechanism
The existing paper signs rely entirely on manual law enforcement, and are intercepted by public security traffic police and environmental protection personnel. The law enforcement costs are high, the efficiency is low, and the implementation is difficult. The national environmental protection system is established with unified national standards and contents. Instruments or handheld PDAs (Environmental Protection, Police Services) can achieve 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 environmental protection, public security, transportation, urban construction and other multi-sector information integration platforms, the electronic sign information can be quickly shared, and the city's comprehensive management of vehicles, such as traffic insurance and automatic charging, can be realized.
