  • Detail

Intel and jihecheng cooperated to build an etc solution based on Intel Architecture


the sustainable development of global economy and urbanization has driven the rapid growth of traffic flow, and the existing traffic infrastructure can not meet the rapidly growing traffic demand. It has become an important task for the traffic management departments of major countries in the world to promote the construction of its (Intelligent Transportation System) through the digitalization and intelligent upgrading of traffic infrastructure. In september2019, the Chinese government issued the outline for building a transportation power. The outline proposes to continuously promote the development of modern comprehensive transportation system and to build China into a world transportation power by 2035

among them, the electronic toll collection (etc: Electronic Toll Collection), as an important part of intelligent highway transportation, is currently playing an important role in scenarios such as road, bridge and parking lot charging, and plays an important role in improving traffic efficiency and mining the value of traffic data

Intel and Shenzhen jihecheng Technology Development Co., Ltd. * (hereinafter referred to as jihecheng * or jhctech) and other partners have launched products and solutions for ETC system, which can collect, process and analyze etc and other traffic data at the edge of the road and in the cloud, help users speed up the deployment of etc system, and lay a solid foundation for the construction of intelligent transportation

background: the rapid development of China's etc construction

etc system can automatically detect and identify vehicles, so that charging transactions can be completed without parking, so that vehicles can quickly pass through the toll station, alleviate the bottleneck effect of toll station delaying traffic, and improve the overall traffic efficiency. In addition to road, bridge and parking lot charging, etc system can also play an important role in traffic control, flow investigation, path identification, congestion charging and governance, and traffic law enforcement based on vehicle identification and financial payment capacity, as well as gantry system and network

therefore, the construction and promotion of etc has become an important part of building a safe, convenient, efficient and green modern comprehensive transportation system. In may2019, the general office of the Ministry of transport of the people's Republic of China issued the notice on vigorously promoting the development and application of etc on expressways, adding that the technical conditions at that time were not enough to overcome the shortcomings of hydraulic transmission itself, requiring to actively promote the installation and use of etc and create conditions for the cancellation of provincial entity toll stations on expressways. According to the plan, by the end of 2019, the automobile etc installation rate in all provinces (autonomous regions and municipalities) in China will reach more than 80%, the vehicle etc utilization rate of expressways will reach more than 90%, and expressways will basically realize non-stop and fast charging

among them, the cancellation of provincial entity toll stations on expressways is of epoch-making significance. It has completely changed the organization and operation mode of expressways, from provincial operation services to full operation services, which helps to accelerate the informatization, intelligence and high-quality development of expressways, improve the travel experience of residents on expressways, promote the efficient development of logistics industry, and make important contributions to economic development

unlike the traditional manual toll (mtc: manual toll vigorously develops a small, ultra-high precision, ultra-high speed and intelligently controlled processing equipment collection), etc uses dedicated short range communications (dsrc: dedicated short range communications) to exchange information between RSU and OBU to complete vehicle identification and send relevant information to the background through the network, Based on the bank account information bound to the vehicle, the settlement is processed to realize automatic non cash payment

etc has been widely used in toll collection of roads, bridges and parking lots, and expressway toll collection is its main application scenario. At present, the ETC system architecture for expressway toll collection in China is shown in Figure 1

it can be seen from Figure 1 that at present, the ETC system of China's expressways includes non gantry stations (including etc lane and etc/mtc mixed Lane) at the entrance and exit of expressways, as well as different toll stations and lane types such as provincial gantry stations and non provincial gantry stations on expressways, which can meet the automatic or manual toll collection needs of traffic vehicles (OBU vehicles and CPC vehicles). Among them, the provincial boundary gantry station is a system erected above the expressway, which has the functions of billing and path identification. It is equipped with RSU that can communicate with OBU, high-definition license plate recognition system, vehicle type classifier, vehicle detector and other equipment. It can identify and charge vehicles under normal high-speed driving conditions, replacing the traditional provincial boundary etc toll station that requires vehicles to slow down, The traffic efficiency is greatly improved

challenge: Design of industrial control computer for ETC system

in the ETC system, the industrial control computer (box PC or industrial PC for short) plays a vital role. It is not only connected with RSU, HD license plate recognition system and other lane equipment, but also connected with the toll station server to complete the calculation, storage and forwarding of etc related data, And control of various Lane equipment. According to the types of etc toll stations and lanes, etc industrial PCs have different functions:

solutions: etc industrial PC solutions based on Intel Architecture

jihecheng has developed a series of etc industrial PCs based on Intel Architecture, including Intel Core CPU, Intel vPro, Intel Intel H110 and Intel q170 chipsets (as well as Intel i219-lm and Intel i211-at Ethernet controllers) have the advantages of powerful computing power, low power consumption, scalable performance, security, reliability and remote management

Intel has worked closely with partners such as jihecheng to realize the etc industrial computer products with close integration of software and hardware and rapid deployment. These products can be widely used in different scenarios, such as provincial border gantry stations, non provincial border gantry stations, non gantry stations at the entrance and exit of expressways (including etc lanes and etc/mtc mixed lanes). These etc industrial computer products comply with strict Chinese and overseas relevant industrial standards and application specifications. They all adopt reinforced fanless design, which can work in a wide temperature range from -35 ℃ to +70 ℃, and have extremely high stability and reliability of dust prevention, corrosion prevention, vibration impact prevention and electromagnetic interference resistance, and can continue to operate reliably and stably under adverse environmental conditions

the models, application scenarios and technical parameters of the above etc industrial computer products are shown in Table 1

effect: significantly improve the traffic efficiency of expressways

with the promotion of canceling the provincial entity toll station project and the continuous upgrading of the system, the requirements of China's expressway etc system for industrial control computers continue to increase. At present, the etc industrial computer solution jointly created by Intel and jihecheng has been successfully applied in the etc systems of different provinces (cities, districts), and well meets the needs of different types of etc toll stations and lanes

according to the statistical data of the Ministry of transport of China, after canceling the provincial boundary real impact testing machine swing rod alignment vertical marker toll station and using the provincial boundary gantry station with etc industrial computer, the average time for passenger cars to pass through the provincial boundary is reduced from 15 seconds to 2 seconds, and the time for freight cars to pass through the provincial boundary is reduced from 29 seconds to 3 seconds. The improvement effect of expressway traffic efficiency is very significant

in the transformation and upgrading of China's etc system, jihecheng etc industrial computer based on Intel Architecture played an important role. Just take the following two examples:

National Expressway G65 (Baotou Maoming Expressway): the expressway crosses mountainous areas in Hunan Province, with frequent climate changes, large altitude drop and harsh environment. Various models of jihecheng etc industrial control computers based on Intel Architecture are used, which are widely deployed in provincial boundary gantry stations, non provincial boundary gantry stations and non gantry stations at various entrances and exits (Figure 2), fully meeting the application needs of users in different scenarios and obtaining high praise from etc users

National Expressway G93 (Chengdu Chongqing Ring Expressway): the traffic flow of some sections of the expressway reaches about 30000/day during holidays, which poses a great challenge to the coping ability of ETC system. After using the jihecheng etc industrial computer, the traffic management department can process the etc billing data at a high speed, meet the needs of stability and reliability, relieve the traffic bottleneck effect caused by manual toll collection or provincial entity toll stations, and further improve the traffic efficiency of the expressway

Outlook: etc will help the vehicle road coordination of intelligent transportation in the future

in addition to realizing road and bridge, parking lot charging and path identification, the existing etc system can also be simply upgraded to carry out traffic control and flow investigation, congestion charging and governance, and cooperate with traffic law enforcement (such as monitoring speeding vehicles and automatically generating tickets)

in the future intelligent transportation system (ITS), etc system can be used as infrastructure to support vehicle infrastructure integration (VII), as shown in Figure 3. On the etc gantry, not only RSU and license plate recognition equipment for etc function can be deployed, but also cameras, radars and other sensing equipment for monitoring road traffic conditions can be deployed. When these sensing devices find abnormal conditions or temporary events, such as road obstacles, traffic accidents and road construction, they can judge the type of events or conditions through artificial intelligence based computer vision and other technologies. According to this, they can generally output these 8 safety messages, and timely notify nearby vehicles or pedestrians through the v2x communication link of RSU to avoid accidents. Meteorological sensors can also be deployed on the etc gantry to analyze and process the abnormal meteorological conditions (such as fog, mass fog, crosswind or hail), generate relevant prompt information, and send it to the vehicle through RSU to ensure driving safety

many scenarios of vehicle road collaboration need to be analyzed and processed by computer vision technology based on artificial intelligence, which will have a high demand for the computing power of the road edge. Mobile edge computing (mec: mobile edge computing) equipment can be deployed on the etc gantry to deal with them. Intel has a deep technical accumulation in the field of artificial intelligence and edge computing, and can provide a rich and diverse product portfolio

as shown in Figure 4, for the computer vision application in the future etc system supporting vehicle road coordination, Intel provides various general-purpose processors with different computing power (including Intel Lexus, core and Xeon R series processing, special vision processing unit, Intel movidius myriad x, and hardware acceleration processing solutions based on Vpu or FPGA. In addition, in order to support the development across different chip platforms, Intel provides openvino software tool suite, which contains rich software tools, which greatly improves the work efficiency of developers and shortens the product development time. Intel has laid a solid foundation for the future development and evolution of ETC system with rich and perfect hardware and software platforms

Intel, a data centric company, will take the world's leading end-to-end technology and strong bottom
