Description
the net business platform Internet of Things smart machine system that the present invention is based on 3G mechanics of communication belongs to Internet of Things field.
Vehicle operating supervisory system is all the major fields of intelligent transportation development for a long time.In the world, the systems such as the IVHS of the U.S., the VICS of Japan, by setting up effective information communication between vehicle and road, have achieved management and the information service of intelligent transportation.And the wireless technologys such as Wi-Fi, RFID also obtain application in recent years in traffic and transport field intelligent management, as intelligent bus orientation management and signal priority, intelligent parking lot management, type of vehicle and flow information collection, road and bridge electric non-stop toll and car speed computational analysis etc. in achieve certain Application effect.
Current car networked system development is complemented each other to coordinate realize mainly through sensor technology, Radio Transmission Technology, mass data processing technology, Data Integration.In the future of car networked system, system function integration, data magnanimity, high transfer rate will be faced.The integrated vehicle instrument desk electronic equipment of car-mounted terminal, as hard disk broadcasting, radio etc., data acquisition also can face multi-channel video and export requirement, therefore for the transmission of image data, needs extensively to use current popular 3G network.
At present, Suzhou gold dragon is by cooperating with Hangzhou Hon Spring Digital Equipment Co., Ltd., vehicle-mounted terminal equipment collection vehicle health data and driver driving behavior are installed before vehicle release, nowadays, researched and developed by Hangzhou Hong Quan company, G-BOS system management vehicle 60000 multiple stage that Suzhou gold dragon uses, but when number of users significantly increases, data are transmitted, filter, store and display is also bearing sizable test always.
In addition, more outstanding car networked system has the black box subsystem of Sweden SCANIA now, vehicle mobile Internet (car networking) system of Hangzhou letter spring.
It is reported, future car networking is by the realization that cooperatively interacts mainly through wireless communication technology, GPS technology and sensing technology.In the car networking epoch in future, can be a kind of relation of complementation between wireless communication technology and sensing technology, when being in the blind area of the sensors such as corner when automobile, wireless communication technology will play a role; And when the dropout of radio communication, sensor can use again.
As the representative of numerous wireless application, the arrival in car networking epoch will promote the application of more wireless technologys and popularize, and we also see the exponential growth of mobile broadband demand again.Although wireless and cable operators also cannot be determined invest in which place, and drop into how many, have any to be affirmative: that is exactly that the demand of mobile broadband is increasing, and increase can be very fast.
At present, General Motors, by cooperating with China Telecom, by its 3G network for user provides vehicle-mounted information service, and progressively build car networking.When customer volume does not also possess scale time, existing carrier network can carry respective services; But when number of users significantly increases, network also will be tested.
The blowout formula that operator is experiencing mobile broadband data traffic increases, because they need increase capacity to reduce the blocking of network, improves the QoE of consumer.Packet network, especially carrier ethernet, can expand to high bandwidth very economically, and the data traffic of process burst.Packet network advanced can be called that the tunnel protocol of " pseudo-line " accomplishes the hybrid transmit of TDM business and burst data services by adopting.All of these factors taken together all makes carrier ethernet become to tackle cost-effectively the new architecture of the mobile broadband data traffic of surge.
Being transitioned into carrier ethernet is the first step, but this is also not enough to have enough competitive power under new environment.Operator also must understand the application that they provide fully, to provide maximum value for their user.This intelligence can have various ways, such as, can be to adopt to be called that depth data bag detects the technology of (DPI) and " understands thoroughly " packet, and determines the application program run.Equipment of future generation can when these packet passing through network, and pry is to packet fast, determines its flow information.These information can combine the grouping core informations such as the type of cell phone of user, position, use, obtain more fully Internet Use analysis, comprise place to use and device type etc., such operator just can utilize these information to improve the experience of client better, obtains new business growth point simultaneously.
After how changing 20 years, what can be the automobile that we drive? in the first theme forum of World Expo, the General Motors Chinese companies president general manager (GM) Gan Wenwei that holds concurrently describes such urban traffic scene: in busy city, vehicle to shuttle back and forth rapidly and in an orderly manner movement under intelligent traffic network commander, even if blind person, also can drive freely; Oil no longer " drunk " by automobile, and green charging station spreads all over the streets and lanes in city, and people can at any time for liking car charging." ' car networking ' technology will redefine automobile NDA." Gan Wenwei says, following automobile will rely on pure driven by power, and pure electric power or hydrogen are the fuel of automobile, by sophisticated electronics with software is overall manipulates.By wireless telecommunications, in city between car and car, between car and buildings, and realize between car and urban infrastructure interconnecting." this is as same bat positioning system, after receiving local message, is promptly delivered in wider network, helps traffic system wagon flow to be assigned in different regions." add high intelligent vehicle driving system, vehicle but never bumps against each other as the shoal of fish in deep-sea is travelling rapidly.The 3D intelligent guidance system that future automobile possesses, just as an intelligent robot, can carry out information interchange with means of transportation, other vehicles, and automatically guiding automobile travels, and does not need people to drive.And portion shows from the investigation of General Motors, at present, in ultra-large type city, the oil of 30% is wasted in the process finding parking stall, cause car owner monthly branched go out 336 yuan, seventy percent car owner at least encounters difficulty of once stopping every day.Orthodox car needs the parking stall more than 10 square metres, and the time of 90% is in dead ship condition." China is potential in world-leading application car networking." Gan Wenwei thinks; Shanghai and even China will become the trial person at first of following personal automobile solution; because Chinese Government is carrying out strong policy encouragement for new forms of energy and intelligent vehicle; the Automobile Market that China more has the whole world maximum, also have powerful automobile industry research and development ability." technology such as electrification, car networking, automatic Pilot has all existed at present, but, the vision of future transportation be realized, need car manufactures and government, Urban Planner and infrastructure expert on the one hand, jointly create suitable applied environment.On the other hand, informationization technology support is also needed to set up city virtual information infrastructure." Gan Wenwei says.But, before eyes, the high price of new-energy automobile also makes consumer be difficult to accept, and hangs back.Gan Wenwei estimates, after 20 years, the price of new-energy automobile only has 1/5th of orthodox car price, and operating cost is compressed to 1/4th.By current electricity charge standard, travel 2.4 ten thousand kilometers and only need cost 840 yuan.
Gordian technique 1, sensor technology and heat transfer agent are integrated:
" car networking is the network between car, road, people ", the sensing technology in car networking applies the mainly sensor network of car and the sensor network on road.The sensor network of car can be divided into again car inner sensor network and car outer sensor network.Car inner sensor network is the network providing the condition information about car to people, and such as remote diagnosis just needs these condition informations, for analyzing the situation judging car; Car outer sensor network is just used to the sensor network of induction car external environment situation, the sensor information of such as anticollision, the camera of induction external environment condition, and these information can be used for strengthening safety and the information as auxiliary driving.The sensor network on road refers to that those lay the network on the way formed with the sensor in roadside, these sensors are used for perception and transmit the condition information on road, as vehicle flowrate, the speed of a motor vehicle, crossing congestion situation etc., these information can allow onboard system obtain information about road and traffic environment.No matter be in car, outside car, or the sensor network of road, all serve the effect of situation and environment sensing in car, its " content " obtaining uniqueness (being different from present internet) for " car networking " integrates these " contents ", namely sensing network information is integrated, to be " car networking " important technical development content, be also the technical development content having characteristic.
2, open, intelligent vehicle-mounted terminal system platform
Just as the computer in internet, the mobile phone in mobile Internet, car-mounted terminal is the medium that car owner obtains car networking final value, can be described as of paramount importance node in network.Current, a lot of car navigation entertainment terminal is also not suitable for the development of " car networking ", and its core reasons have employed non-opening, non intelligent terminal system platform.Be difficult to be forged into network ecosystem based on terminal system platform that is open, intelligence not.This respect can experience the important of this point referring to smart mobile phone field: a large amount of developers constructs the application of hundreds of thousands money based on IOS and the Google Android terminal operating system of Apple, and these are applied as these two cell phone network ecosystems and create core value.And everything is all because developer can apply based on such system development, the particularly android system of Google, source code opening completely, can be reduced and be optimized.Therefore, GoogleAndroid also will become the mainstream operation system of car networked terminals system at present, it is natural gives birth to for network application, and aim at touch operation design, experience good, personalized, application is enriched and number of applications increases fast, has defined ripe network ecosystem.Review the WinCE that current vehicle mounted terminal is with the most use, can be described as a closed system, be difficult to the space made further progress, because apply pitiably little, any amendment is all helpless due to the closed strategy of Microsoft, work laboriously to develop function of surfing the Net, indistinctive application and serve available.Roewe 350 and INKANET thereof on front dress market, the Android platform product of smooth science and technology of setting out on a journey in rear dress market has demonstrated the value of Android, the inevitable choice that Android will be car entertainment navigation terminal platform operating system.
3, speech recognition technology
No matter how good touch is experienced, and concerning motorist, in driving conditions, touch operation terminal system is all unsafe, and therefore speech recognition technology seems particularly important, the roll booster that it will be car networking development.Ripe voice technology can allow driver be issued order the service of asking for car networking by face, can receive car network the service provided with ear, and this is best suited for application experience of this quick mobile space of car.Ripe speech recognition technology depends on powerful corpus and arithmetic capability, therefore the development of vehicle-mounted voice technology inherently must depend on network, because the storage capacity of car-mounted terminal and arithmetic capability all cannot resolve the speech recognition technology of on-fixed order, and must adopt " cloud identification " technology based on service end technology;
4, service end calculates and service assembly technology
Except above-mentioned speech recognition will be used except cloud computing technology, the providing of a lot of application and service all will adopt that service end calculates, the technology of cloud computing.Similar internet and mobile Internet, terminal capability is limited, and calculated by service end and could integrate more information and resource and to provide to terminal and serve timely, service end calculating starts to enter the cloud computing epoch.Cloud computing will be used for analytical calculation road conditions, extensive vehicle path planning, intelligent traffic dispatching meter, vehicle diagnostics calculating etc. based on huge case in car networking.Car networking carrys out Realizing Service Innovation with internet, the same service assembly that all must adopt of mobile Internet, provides value added service.By service assembly, car-mounted terminal can be made to obtain more suitable more valuable service, preengage as call center services and vehicle insurance business integration, remote diagnosis and Site Service integrate, location-based service and merchant service integrate etc.;
5, communication and application technology thereof
The main communication technology relying on two aspects of car networking: short-distance wireless communication and remote mobile communication technology, the former mainly RFID sensing set and the 2.4G communication technology such as similar WIFI, the latter is the mobile communication technology such as GPRS, 3G, LTE, 4G mainly.This two classes communication technology is not the exclusive technology of car networking, therefore the application of technical development emphasis mainly these communication technologys, comprises the mobile communication technology application such as the short-distance wireless communication application such as highway and parking factory automatic fee, wireless device be interconnected and VOIP application (automobile friend online, fleet navigate), monitoring and scheduling data packet transmission, video monitoring.
6, Internet technology
The essence of car networking is exactly the fusion of Internet of Things and mobile Internet.Car networking is by integrating car, road, the various information of people and service, final is all for people (people in car and the people paid close attention in car) provides service, therefore, what can obtain that car networks the information that provides and service is not only car-mounted terminal, but all terminals can accessing internet and mobile Internet, therefore computer, mobile phone are also the terminals of car networking.The application of existing internet and mobile Internet can both use substantially in car networking, comprises media entertainment, ecommerce, Web2.0 application, information service etc.Certainly, car networking is compared with existing common interconnection network, mobile Internet, and it has two key characteristics: be correlated with in a Shi Yuchehe road, two is as key element using positional information.Therefore need, around the characteristic internet, applications of this two key characteristic development cars networking, user and ISP more widely to be brought to car networking.
The above-mentioned technology of development prospect and application should be that car networking needs the technology given priority to and application in the recent period, and these technology and apply that to segment be very huge technical system, therefore need many manufacturers to cooperate together jointly to make this network ecosystem.But, do not really want first to have built up application and the service that complete technical system can develop car networking.The same with present internet, valuable to user, can allow user have the segmentation of good experience apply all will succeed.Over the past two years, no matter be general introducing OnStar on front dress market, Toyota introduces G-BOOK to China, or the smooth science and technology in road takes the lead in pushing to the car internet services iBook in rear dress market, all demonstrates car and networks on the way.Just as PC comes into internet, mobile phone comes into that mobile Internet is the same, automobile will be come into car networking, and can walk very fast, far.
Opportunity to develop 1, country are the institutional basis of car networking development to the attention of Internet of Things and policy support
Through 2 years ferment and develop, Internet of Things began to take shape.In the government work report of two Conferences in 2012, Internet of Things is carried again as strategic new industry.The Ministry of Industry and Information Technology is at its website orientation " Internet of Things " 12 " development plan ", this is first Internet of Things planning in China's five-year-plan history, clearly propose in planning, Internet of Things will take the lead in disposing with an emphasis [8] in fields such as intelligent grid, intelligent transportation, Intelligent logistics, finance and service sectors.
Car networking, as the important application of Internet of Things in automobile industry, has now been listed in the main project of country " 12 " period.At present, the Ministry of Industry and Information Technology sets about from the many-side such as estate planning, technical standard, strengthens the supporting dynamics to vehicle-mounted information service, to advance the fully under way of car Networking industries.In addition, Chinese Government also has strong policy to encourage for new forms of energy and intelligent vehicle.Predictably, car networking also will welcome more support policy.
Country is promote the fast-developing important institutional guarantee of China's car networking for the attention degree of Internet of Things and related industry thereof.At present, State Council discloses the decision about accelerating cultivation and development strategy new industry: to the year two thousand twenty, energy-conserving and environment-protective, generation information technology, biology, high-end equipment manufacturing industry become mainstay of the national economy industry, and new forms of energy, new material, new-energy automobile industry become the guiding industry of national economy.
2, technical foundation has been established in the car networking that develops into of automotive electronics and information transmission network
Car networking is another mark of following intelligent city after internet, Internet of Things.Compare conventional mobile communications service, the application of car networking has the feature of wider class of business, longer value chain, more specialized demand.At technological layer, car networking needs first to obtain various information by various sensor, as information sensing equipment such as radio-frequency (RF) identification, infrared inductor, GPS, laser scanners, these equipment can provide basis for the message exchange of garage, thus realize intelligentized identification, location, tracking, monitor and managment.In recent years, the development of the domestic Sensor Network based on RFID technology was swift and violent, and car networking development important foundation--automotive electronics is also in fast development.Automotive electronics is that car is networked the basis be achieved, various automobile sensor particularly in automotive electronics and actuator etc., they are one of the gordian techniquies promoting automotive circuit diagram, robotization, intelligent development, to some automobile electronic system, as engine electric-controlled, air bag system, sensor cost accounts for 70% of system synthesis basis.Countries in the world are to the research and development of automobile sensor and how to improve cost performance and all pay much attention to.Automotive electronics reaches all the more, and automaticity is higher, larger to the dependence of sensor.So, all automobile sensor technology is classified as the new and high technology given priority to both at home and abroad.In addition to the sensors, vehicular automotive electronic equipment is also that car is networked the important carrier be achieved, and comprises navigational system, vehicle entertainment system etc.
In addition, information transmission network is also that car is networked one of requisite sport technique segment.At present, China three has built up the Base communication net covering the whole nation in operation commercial city greatly.The particularly construction of 3G network, this is build car networking to provide solid network foundation.
All in all, car networking is node and information source with car, the information of acquisition to be connected in platform network by technological means such as radio communications and to be analyzed and manage, its core is exactly acquisition of information and FEEDBACK CONTROL, thus realizes Che Yu road, Che Yuche, being interconnected of car and urban network.It along with urban traffic blocking day by day increase the weight of and the continuous progress of intelligent transportation solution technology occurs, China has abundant bandwidth resources and mobile communications network, and automobile pollution is large, this makes China's development car networking have a lot of advantage.
3, healthy, that harmonious urbanization system the is promotion car networking development market demand is built
Along with China's expanding economy, the industrialization of national economy, urban population constantly increases, and urbanization has become a kind of inexorable trend in China.The "urban disease" such as the traffic congestion that urbanization brings, car accident, environmental pollution, has become a difficult problem lain across in face of urban development, and this has higher requirement to the urban system that Urbanization is reasonable, harmonious with structure.
China is the maximum producing country of Global Auto and country of consumption, and car networked marketplace is huge, and vehicle has become the important component part in city.From this emerging mobile terminal of automobile, to the car networked system be made up of automobile, affect the vital economic train of thought of the another bar of China.Especially, in two Conferences in this year, after the social concern such as intelligent transportation, safety of school bus becomes subject under discussion, various circles of society pay attention to especially to problems such as traffic jam, school bus accident, in-vehicle exposures, all wish that government can formulate strong solution.
4, car networking development need set up the collaborative ecosystem
Internet of Things think tank thinks that China's car networking is still in such stage so far: main flow depot sells " attraction " of car, the means that intelligent transportation " ETC " is charged, the battlefield of TSP and telecom operators' arguement charge height.Situation outside this about corresponding country before 3 years.When be drive with innovation, take safety as target, centered by consumer, when just can have the cooperative development that Chinese car is networked.
Car networking has developed 10 years, and the past is that automobile manufacturing company instructs always.After 10 years, manufacturers find that new car is sold and had attraction, but car networking itself does not bring value, and all pass by 10 years TSP be in the world all loss, and its popularity rate is not to 10%, and all users are unwilling paying.Because it is completely by the operation system closed that automobile vendor controls, automobile industry is not had an impact, related industry is not had an impact yet.So other field? such as commercial truck fleets management, this have also been made 10 years, commercial truck fleets major part is also equipped with equipment, but commercial truck fleets amount transport does not really need Internet of Things, but need the mode of production re-constructing oneself, the car networking of commercial truck fleets does not also reach the permeability of 20%, does not create real value to transport column.
After realizing car networking, the electronic technology of the IT technology of automobile manufacturing company and automobile itself combines together.Audi of U.S. car is the online navigation Service using Google entirely, and LTE also often comes into effect.Verizon has purchased maximum car internet services provider Hughes Telematics, also have Sprint can provide independently end-to-end insurance car networking UBI service, prevented by the means of premium height the level that illegal activities improve traffic safety, insurance car the whole of last year of networking has developed 300 general-purpose families.
Past people discuss car networking, and focus is always in device and the function thereof of network and Che Nei.When recent cloud computing is in fashion, many people hanker after general PaaS platform.Until when discussing the car networking creation of value today, such as, when providing UBI to serve, large data are the focus of people's care.There is research in Cisco in this respect, if use car networking, loss can reduce by 35%, and the expense of 58 dollars can be reduced every year, the expense oneself will paid after comprising insurance, collision, also has public security management, camera and expense violating the regulations, this expense is very high, so car networking brings very large benefit.
The confinement of jumping out traditional vehicle networking is needed in the car networking of China badly, and new markets and the NPD projects of setting up collaborative car networking are ecological.The maximum feature of nascent state is optimized by the business model of car networking to automobile, repair and maintenance, finance, insurance, traffic, transport, each traditional field of security and consumer to obtain new value.Various car networking association should make efforts in this, finds the point of penetration that universal and acquisition is fast worth in numerous industry.
The networking of support on policy car is the utilization of Internet of Things at intelligent transportation field, and car networking project is the important component part of intelligent transportation system.Enter into the new century, the concept such as Internet of Things, the wisdom earth, smart city is risen, and the application specific to field of traffic just creates the concept of wisdom traffic, car networking.The concept of Internet of Things, just put forward as far back as 1999 in China, be not " Internet of Things " at that time and be Sensor Network, the generation of Internet of Things concept and the fast development of Internet of Things industry, cross with intelligent transportation and merge, the new trend-Che creating intelligent transportation industry networks.
Car networking is exactly moving vehicle Internet of Things, refer to and utilize vehicle electronics Chuan Gan Zhuan Ge, by mobile communication technology, auto-navigation system, intelligent terminal and information network platform, Shi Cheyu road, Che Yuche, Che Yuren, real-time interconnection between car and city, realize information interconnection and intercommunication, thus the network system of effective intelligent monitoring, scheduling, management is carried out to car, people, thing, road, Wei Ge etc.
Only the part relevant to " people-Che " is vehicle-mounted information service system (Telematics), the namely automobile Internet of Things of " narrow sense " abroad.Telematics is for platform with wireless speech, digital communication and satellite navigation and location system, by positioning system and wireless communication networks, provide transport information to driver and passenger, emergency condition deals with countermeasure, remote vehicle diagnosis and internet (financial transaction, news, the Email etc.) integrated information service system of serving.
Car networking is a huge wireless sensor network in essence.Each automobile can be regarded as a super sensor node, and a usual motor vehicle equipment has inside and outside thermometer, luminance sensor, one or more camera, microphone ultrasonic radar, and other equipments many.At present, a general car about installs more than 100 sensor, limousine sensor even nearly more than 200.In addition, following automobile will be equipped with truck-mounted computer, GPS orientator and receive and dispatch Zhuan Ge etc. Wu line.This makes between automobile, and can radio communication between automobile and roadside base station.This unprecedented wireless sensor network extends computer system to the perception of All Around The World and control ability.
Car networking project has been listed in the big event in national key special subjects (the 3rd is special), downpayment fund input reaches 10,000,000,000 and implements the most important thing that national science and technology key special subjects is scientific and technical research, key special subjects Section 3 in " country's " 12 " scientific and technological development planning " requires: accelerate to break through the core technologies such as mobile Internet, broadband cluster system, new generation of wireless LAN (Local Area Network) and Internet of Things, promotion industry is applied, promote that operating service innovation and intellecture property are created, strengthen Industry Core Competitive.And car networking project is as the core application in Internet of Things field, first phase fund input reaches 10,000,000,000 ranks, and support fund will concentrate on automotive electronics, information communication and software solution field.
" 2012-2020 China intelligent transportation development strategy " is about to put into effect, and intelligent transportation industrial investment will start new upsurge with development.On July 31st, 2012 was to August 1,3rd the Intelligent transport conference (ITSCC) of being sponsored by Research Institute of Highway Ministry Transport and the Beijing Communication council is held in Beijing, and the relevant responsible official of science and technology department of inter-Congress period Department of Transportation has openly resolved " 2012-2020 China intelligent transportation development strategy " first time." strategy " proposes, to the year two thousand twenty, the overall goal of China's intelligent transportation development is: basically form the intelligent transportation system adapting to the requirement of Modern Traffic transportation development, realize trans-regional, large-scale intelligent transportation Integrated predict model and synthetic operation, trip service easily and efficient logistics service are provided, take a firm foundation for the middle of this century realizes communications and transportation modernization.Objectives are, General Promotion urban traffic control and service level; Effective raising highway traffic safety and trip reliability; Put forth effort to strengthen water-borne transport efficiency and supervision emergency capability; The multiple means of transportation of remarkable promotion is effectively connected; Significantly improve capacity for technological innovation; Promote to form intelligent transportation industry.For realizing above-mentioned target, emphasis is supported the integrated innovation that traffic data Real-time Obtaining, transport information are mutual, transport data processing, intelligent traffic safe and intelligent organize the technology such as management and control.Also will accelerate the formulation of the basic key criterion of intelligent transportation, application service standard, promote standard carrying out and perform and international co-operation.
Compared with the field such as intelligent grid, security protection, car networking be not the most ripe, apply closest to the Internet of Things of practical application, but by means of its strategic height and huge consumer level market, still won strong concern.
The appearance of car networking, brings industrial upgrading opportunity for automobile making, content provide with the field such as mobile communication.Impel automobile industry to sell from plain hardware on the one hand, transfer the new model with service, ties content to; On the other hand, allow again operator and service provider be located rapidly high-end customer colony, be convenient to provide products & services.In addition, the requirement that country " must possess remote monitoring ability " to new-energy automobile, also allows car network across two great strategy new industries.
So-called car networking there is no strict difinition, briefly, is exactly using automobile as the node in information network, is realized the cooperation interaction of people, car, road and environment, realize intelligent transportation by means such as radio communications.But from being born, car networking just faces " unmanned " situation lacking unified management body all the time.
Compare three large administrative authoritys, the interest that mobile operator, automotive electronics enterprise, content supplier, service provider network to participation car is more positive.Because car Networking industries chain is longer, participate in industry numerous, can be found everywhere to the understanding of car networking " taking a part for the whole " formula, interest game wherein also can hardly be avoided.
Technology short slab
Along with the birth of car networking concepts, automotive electronics also changes into from original emphasize system combination ability based on machinery, safety, and car and car, cooperation interaction between car and environment.
Car is networked the message exchange and sharing problem that will solve between each system, simultaneously with driver and the existing effective interaction of passenger real.In addition, car networking is connected by vehicle body network, can also obtain various kinds of sensors data in vehicle body, for reporting to the police or remote diagnosis after process.But most high end sensor being used for information acquisition, its chip core technology is not by Chinese companies is grasped.
Meanwhile, communication network bandwidth bottleneck, also becomes car and to network a technical barrier.Current 3G network bandwidth can not meet the following transmission demand to image and Streaming Media, and the hoc network technology etc. of 4G network and DSRC (Dedicated Short Range Communications) does not yet break through completely.
Being converged to data center when gathering the information of coming up, also will be stored it, mutual and analyze, domestic in cloud computing and super mass data processing, also do not grasp core technology.Finally, in Overall Acquisition system accurately Information base, for the intelligent processing method of different application, a global difficult problem especially, needs extensive work to study the mathematical model of intelligent Application.
Domestic at present possess certain level in chip design and exploitation, but independently controlled can the problem of pipe still severe.The internet domain name system of China and address, and article bar code, be all external technical system, coded address, car networking can not follow the track of the overturned cart on vehicles identifications.
In fact, the Ministry of Public Security has released the electronic label special of a kind of discrimination more than 99.9%, can be arranged on windshield, forms the unique identification to testing vehicle register and positional information.But, to follow the tracks of information of vehicles, also need the data acquisition facility disposing certain density at guarded region.
Pattern is difficult to walk
In face of the temptation of huge market, the relevant enterprise of car networking is reluctant to sit back and wait that Technology and Administration breaks office.Telecom operators, automotive electronics and service enterprise, even automotive trade enterprise, start to push ahead with a kind of car networking operation mode simplifying version---and carry out integrated around vehicle intelligent platform, realize the integration of content and application.
By means of the advantage of mobile network's passage, the propulsion mode of current three large operators in car networking, substantially be that vehicle intelligent terminal is connected with radio channel, to provide the operating service such as real-time traffic, navigation, rescue location, vehicle condition detection, the reservation of 4S shop, many based on call center or mobile Internet, do not relate to any new technology, to be only equivalent on existing network basis a new business development.
Real car networking should be multiple information systemintegration, and the information between people, car, road, environment is intercommunication, and the car based on technology of Internet of things is networked.
Present relevant criterion is not completely put into effect, and the starting stage all can not calculate.But can realize under prior art condition, at once to see benefit, also only have this pattern.
Even if but existing this pattern, also can not guarantee the success in business model.What is called " car networking " products & services come into the market at present are all that automaker replaces terminal user to foot the bill, usual 1 year to 3 years, to the after date service of whether initiatively renewing a contract or unknown number.
Operation mode is as the important common factor in the large field of Internet of Things and intelligent vehicle two, and car networking is collected by automobile, process, share road and information of vehicles, by the multiple interaction of people and car, Che Yuche, car and control center, realizes the Intelligent life on wheel.
One, the marketable value of car networking
The birth of car networking industry is not propagandized, and itself has out and out marketable value to exist:
1, reduce dispute after sale, all are spoken by data
Car networked system can be monitored and preserve the service data of vehicle, when vehicle breaks down, and therefore cause client to lose, the controversial issue of both sides can be calmed down by data, help client to avoid the mistake repeating operation lack of standardization, this point is especially very effective in passenger traffic industry.
2, on-line tracing, avoids the loss of accessory consumptive material sales opportunnities
By the collection to vehicle operation data, also form the service condition report of accessory, consumptive material simultaneously, before needs replacing, lock the sales opportunnities of accessory, consumptive material and maintenance in time.
3, fault pre-alarming, avoids major accident
General car networked system, has a set of management platform, and platform can generate the historical data analysis form of various theme, trend report, and by mode report exceptions such as the page, mail, notes, avoids glitch to bring major break down.
4, after-sales service cost is reduced
Grasp vehicle operation data, meaning can fault analysis and judgement reason.For can the fault of long-range eliminating, to go on business cost with regard to reduction personnel.
5, form the business model manufacturing+serve, change service provider into from single vehicle manufacturers, form the differentiation of products & services, avoid direct price to compete
Vehicle manufacturers can to client's added selling long-distance management system, also can by providing visual management service, third party can be settled by oneself or entrusted to collect service fee on the one hand, vehicle attraction can be increased on the other hand by multiple service, come better " selling car ", avoid cruel direct price competition.
Two, car networking operation mode
Car Networking industries chain is divided into following 5 roles: depot, car owner, Virtual network operator, technology provider (software and hardware), content supplier.
Depot: as the dominant role of car networking, be the value interests hinge of whole piece industrial chain, propose development requirement to technology provider, content supplier, better sell car to End-Customer, thus acquire an advantage, other roles closely these interests imputed in industrial chain.
Car owner: after all,the wool still comes from the sheep's back, final all expenses, still can be born by car owner; Bearing way is by a variety of, the mode of more satisfactoryization, stood out to dominate by a certain role in industrial chain and collect operation maintenance expense, but the consumer psychology of domestic correspondent, add that Present Domestic present stage car networking technology is not experienced to the value that client is very good, how collecting operation maintenance expense becomes a great problem.
So the birth of current vehicle networked system, its fundamental purpose of Ge great main engine plants should be in the market competition of excitation, increases vehicle attraction, better sells car, avoid cruel price competition.
Although every technology relative maturity of car networking, but the essence of car networking is the information integration and the real-time management that realize " bus or train route integration ", i.e. all relevant informations of integrated vehicle and road traffic, do what stage you think the networking of current car develops into? realizing on this crucial ring of information integration, also have the difficulty in which technology or policy?
Car networking technology itself just computing machine electronic technology and one use, a kind of information integration mode, its bottleneck not in technology, and is that put in place degree, supporting of information integration puts in place degree.Current vehicle networking industry has begun to take shape, and there is oneself so-called " car networking " system in most of depot, and whether system possesses core competitiveness, will see that can system bring abundance, satisfied information service to client.
Can car networking technology extensively use, and this obtains branch trade.First say commercial car, inside commercial car, lorry and passenger vehicle can be divided into again.The car networked system of passenger vehicle, that more famous is the golden imperial G-BOS in Suzhou, the theory of G-BOS system: quality and vehicle safety hidden danger, the vehicle oil consumption of driver driving behavior also have vehicle service life closely bound up.Just in the month before, G-BOS wisdom operation system is written into it " Internet of Things and intelligent transportation " book of this series.
