The main components of RFID low-carbon transportation construction

When environmental protection became a global consensus, low-carbon concepts came into being. As the frontier trend of urban transportation development, intelligent transportation also cannot avoid the “invasion” of low-carbon concepts. The development of low-carbon transportation is an inevitable trend. Using RFID technology, through the development of electronic environmental protection sign systems, the classification and control management of automobiles according to different emission standards, and setting up low-carbon traffic areas on this basis are inevitable in the current “perception of China” environment. select.

Low-carbon smart traffic came into being

Over the past one hundred years (l906-2005), the average global surface temperature has increased by 0.74 degrees Celsius, and in the next 20 years, the global temperature will increase by 0.2 degrees Celsius every decade. 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 the countermeasures for low-carbon transportation, such as the classification and management of cars with different emission standards, and the use of scientific and technological means and taxation systems to control carbon emissions. Such as Europe, Britain, Sweden, Germany, Italy, Norway, Asia, Singapore, Tokyo, Taiwan, Hong Kong, Australia and other countries and regions through the establishment of low-carbon traffic areas, low emission areas, green traffic areas, clean demonstration areas, both It ensures the air quality in the region and encourages the use of clean transportation.

Through the construction of a low-carbon transportation area, the urban traffic pattern of “high-contamination yellow-marked vehicles banned from passing, ordinary emission vehicles restricted or toll-passing, and zero-emission vehicles traveling freely” will be formed in cities, which will promote the elimination of highly polluting vehicles and encourage them. The use of low-carbon emissions such as hybrid electric vehicles, especially zero-carbon emission of pure electric vehicles and other new energy vehicles will play an impetus role and at the same time effectively solve the urban congestion problem and truly achieve low-carbon transportation, energy conservation and emission reduction, and improvement. The purpose of air quality.

Through the establishment of a low-carbon transportation tourism zone and a low-emission demonstration zone, vehicle emissions will be basically eliminated within a certain area, and the city’s ambient air quality will be improved, and in particular, the air quality around the road will be improved. Through demonstration projects, more people 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 area system is mainly composed of four parts: environmental protection electronic signs, vehicle-aware base stations, environmental monitoring base stations, and regulatory control platforms.

Electronic environmental protection sign. The 900M RFID electronic sign is used. This electronic sign contains vehicle information such as license plate number, vehicle model, and emission standard. It also has a unique identification code that replaces the conventional conventional paper-based environmental protection sign and forms a unique correspondence with the vehicle.

Vehicle aware base station. Using double-based identification technology (ie, video radio frequency), radio frequency identification can realize the non-contact automatic identification of electronic tags, and can detect the electronic tags on vehicles with high speed (180km/h) at a long distance (up to about 15m). Read and write; Through the video recognition to achieve license plate recognition, photo forensics, and can match the radio frequency identification results.

Environmental monitoring base station. Established on both sides of the road, it can detect and warn motor vehicle pollution in the urban road network in real time.

Regulatory control platform. It is the brain of the low-carbon traffic area system and is responsible for intelligent analysis of the transmitted identification information and environmental information. It coordinates with the environmental protection and public security business processing platform to realize the analysis and processing of the regulatory business of low-carbon traffic areas.

The main components of RFID low-carbon transportation construction

The application of RFID in low-carbon transportation construction includes the following parts:

1. Apply to the construction of the green intelligent transportation system to realize both the prevention and pollution control

The symbiosis of congestion and pollution, the more congestion, the more serious the pollution, and the greater the harm to humans. Under normal circumstances, exhaust emissions when the vehicle is traveling at a speed of 20 km/h are more than double that at 40 km/h. Using electronic environmental protection signs as the carrier, using the Internet of Things technology, establishing an intelligent transportation system, collecting, organizing, and analyzing comprehensive traffic information, and conducting traffic control according to road congestion conditions, so that the flow of traffic on the road network can be operated in an optimal state, thereby improving Traffic jams reduce vehicle pollution. It has been estimated that it can reduce motor vehicle pollutant emissions by 15%-20%.

2. Apply to bus priority system

Electronic environmental labels can meet the needs of automatic signal acquisition, and serve the development of public transportation, adherence to public transportation priority strategies, and construction of bus-only roads and public traffic priority signal systems. By increasing the speed of bus transportation, a bus rapid transit system will be formed, which will increase the bus trip rate, reduce the proportion of private car trips, and reduce tail gas emissions.

3, applied to high pollution yellow label car and non-standard car law enforcement

Highly-polluting yellow-standard vehicles refer to motor vehicles whose emission standards do not meet the national standards. Non-standard vehicles refer to vehicles that cannot receive environmental protection signs without passing the environmental protection annual inspection or environmental protection annual inspection. Although the yellow-labeled vehicles and non-standard vehicles only account for 10%-15% of the total number of motor vehicles in the city, the discharged pollutants amount to 50% of the total amount of motor vehicle emissions. The use of electronic environmental protection signs and the establishment of a regional restricted-line system for Internet of Things technology can realize the integration of the vehicle information system, environmental protection supervision system, and road access system, thereby realizing the uniqueness of the identification of vehicle signs and improving the accuracy of limit-based management. High efficiency.

4. Traffic control applied to vehicles with different emission standards

Try the congestion charging policy and set up a low-carbon traffic area. That is, on the basis of setting restrictions on the yellow-labeled vehicles and non-standard vehicles, a low-carbon traffic area that allows only free energy vehicles, pure electric vehicles, and automobiles above the country to pass through will be established. Other countries, such as countries, will use different types of vehicles. Emission level classification charges pass.

5. Verification of environmental protection applied to vehicle license plates, annual inspections, and road inspections

The use of electronic environmental protection signs can effectively realize the online auditing of motor vehicle management on board management and public security reading to ensure 100% environmental compliance of the vehicle on the vehicle; it can effectively prevent the cheating of tail gas inspection and inspection; Law enforcement terminal, remotely query vehicle information, and investigate and punish the functions of yellow-marked vehicles, non-standard vehicles, invalid vehicles, counterfeit vehicles and counterfeit vehicles on the spot.

6. Apply to traffic pollution intelligent monitoring online regulation system

Establish environmental pollution monitoring systems on both sides of roads and vehicle pollution. Real-time detection and warning of motor vehicle pollution in urban road networks. Combine intelligent transportation systems and use electronic environmental protection signs to intelligently control vehicle traffic.

7. Apply to the national motor vehicle pollution prevention joint control mechanism

The existing paper logos are completely based on human law enforcement. They are blocked by public security traffic police and inspected by environmental protection personnel. The enforcement costs are high, the efficiency is low, and enforcement is difficult. An electronic environmental protection sign system that establishes national uniform standards and contents is established. Instruments or handheld PDAs (Environmental Protection and Police Affairs) can realize mutual recognition of signs between cities and truly achieve joint defense and control.

8. Information sharing applied to other government departments

Through the development of environmental protection, public security, transportation, urban construction and other multi-sectoral information integration platforms, the rapid sharing of electronic sign information is realized, and comprehensive management of vehicles in cities is realized, such as compulsory insurance and automatic metering.

The status of intelligent traffic applications in China

Nowadays, people from all walks of life are talking about intelligent transportation because it is closely related to people’s livelihood issues. Well, we must first clearly understand what is meant by “intelligence transportation”. It can be said that under the booming construction of smart cities, intelligent transportation is a branch of its construction, and it is also the development direction of the future transportation system. It is advanced information technology, Data communication transmission technology, electronic sensing technology, control technology and computer technology, etc. effectively integrate a comprehensive, real-time, accurate, and efficient transportation system that is used in a wide range of areas and functions in a comprehensive way. Transportation management system.

Intelligent transportation can effectively use existing transportation facilities, reduce traffic load and environmental pollution, ensure traffic safety, and improve transportation efficiency. As a result, it has increasingly attracted the attention of various countries. In China, there are many problems in the development of transportation. For example, infrastructure shortages and their inefficient use coexist; road transport facilities cannot meet the needs of economic development; most transportation facilities are heavily overloaded; traffic congestion is severe and transportation efficiency is declining. Travel time was wasted and increased air pollution in cities. The exhaust of motor vehicles has become the main source of urban air pollution. Intelligent traffic is a product born at the historic moment and it will inevitably need to solve its traffic problems. Therefore, China’s intelligent transportation is mainly used in three major areas:

1. Informatization of highway traffic, including highway construction, provincial highway construction

The current hotspot projects in the field of highway transportation are mainly concentrated on highway tolls, and software is the main one. The highway toll project is divided into two parts, the online charging software and the toll collection system. In addition, IETC is the main way for future highway toll collection.

2. Informatization of urban road traffic management services

Compatibility and integration are the main problems in the informationization of urban road traffic management services. Therefore, a comprehensive information platform has become a hot topic in this field. In addition to the urban traffic integrated information platform, some of the more promising vertical applications include intelligent signal control systems, electronic police, and onboard navigation systems.

3, urban public transport informatization

At present, the informatization application of public transport systems in China is still relatively backward. The smart public transport dispatching system is basically in a blank stage in China, and is also an area where planners can focus on development. In terms of geographical distribution, major cities in the country, especially the southern coastal areas, attach great importance to the development of intelligent transportation.
