RFID can not only sense the position of the object, but also sense the movement state of the object and tracking.RFID positioning method has been widely used in the field of intelligent transportation, especially in the car networking technology is a strong dependence on RFID technology, and has become the basic technology of the car networking system.RFID technology is generally used in combination with servers, databases, cloud computing, short-range wireless communication and other technologies, by a large number of RFID through the Internet of Things to form a huge object recognition system.
2, sensor network technology
Vehicle services require a large amount of data support, the original source of these data is collected by various types of sensors. Different sensors or a large number of sensors through the collection system to form a huge data acquisition system, dynamic collection of all the original data needed for vehicle networking services, such as vehicle location, state parameters, traffic information. The current sensors have evolved from a single or a few sensors to a sensor network composed of a large number of sensors, and the pass can be customized according to different services. Provide a data source for the server, after analyzing and processing as the business data to provide quality services for the vehicle.
3, satellite positioning technology
With the development of global positioning technology, the development of Telematics ushered in a new historical opportunity, the traditional GPS system has become an important technical basis for Telematics technology, for the vehicle positioning and navigation to provide a high-precision and reliable location services, and has become one of the core business of Telematics. With the increasing improvement of China's BeiDou navigation system and put into use, Telematics technology has a new development direction, and gradually realize the transition to the period of localization and independent intellectual property rights. Beidou navigation system will become one of the core technologies of China's car networking system, and become an important beginning of the independent research and development of the core technology of car networking.
4, wireless communication technology
Sensing network acquisition of a small amount of processing needs to be transmitted by the communication system out of the cloud in order to get timely processing and analysis, the analyzed data also need to go through the transmission of the communication network in order to reach the vehicle terminal equipment. Considering the mobile characteristics of vehicles, car networking technology can only use wireless communication technology for data transmission, so wireless communication technology is one of the core components of car networking technology. With the support of various wireless transmission technologies, data can be exchanged under the control of the server, realizing real-time transmission of business data and real-time monitoring and control of vehicles in the network through the transmission of commands.
5, big data analysis technology
BigData (BigData) refers to the use of computer technology, the Internet, to capture a large number of complex structure of data or information aggregates. Driven by the development of computer technology and network technology, various big data processing methods have begun to be widely used. Common big data technologies include information management systems, distributed databases, data mining, class clustering analysis, etc., which have become a powerful driving force to continuously promote the application of big data in Telematics.
6, standards and security system
The Telematics, as a huge Internet of Things application system, contains a large amount of data, processing and transmission nodes, and its efficient operation must be regulated by a set of unified standard system, so as to ensure the authenticity and completeness of the data, and to complete the application of various businesses. Standardization has become an urgent requirement for the development of vehicle networking technology and a complex management technology. In addition, vehicle networking and access to services itself is also to better provide security for vehicle safety, so the establishment of the security system is also very important. The ability to establish a set of efficient standards and safety systems based on the current development of vehicle networking has become a key factor in determining the future development of vehicle networking technology.
Bottlenecks in the development of Telematics
1, industry barriers are difficult to break, the government's cross-sectoral cooperation is not in-depth
The Telematics industry is an emerging industry involving many industries, only when there are enough participants to maximize its network effect and value. Many veteran car companies have the advantage of industry technology and experience, but the lack of Internet thinking, for cooperation with technology companies to hold a relatively conservative attitude, neither willing to be left behind in the car networking competition, but also unwilling to give up the opportunity of car networking to technology companies. The emerging Internet technology enterprises, eager to enter the field of car networking, although mastered artificial intelligence, big data analysis and other technologies, but there is no core vehicle carrier and due to the accumulation of technology. In general, there is a lack of extensive cooperation and effective cross-industry cooperation platform between vehicle companies and Internet technology companies [5]. In addition, the cross-industry and cross-domain attributes of Telematics mean that multiple sectors need to cooperate and **** together to promote it in terms of policies, key technologies, application models and standards development. Although the Ministry of Industry and Information Technology (MIIT) has issued a series of guidance documents such as the Intelligent Networked Vehicle Technology Roadmap, there is still a long way to go from the documents to implementation.
2, has not yet formed a mature business model, corporate profitability can not be guaranteed
Enterprises have not yet found a mature business operating model, profitability and low user renewal rate of the problem is prominent. At present, the domestic car networking enterprise profit source is mainly consumers, but the lack of attractive products and services, user stickiness is generally low, this relatively single way of buying and selling and business operation mode, but also can not continue to bring added value for the user, resulting in car networking even if by the enterprise attaches great importance to the promotion of consumers is still a lot of resistance, the majority of consumers for the intelligent networked vehicles hold a wait-and-see attitude, the profitability of the enterprise can not be guaranteed. Most consumers have a wait-and-see attitude towards smart connected cars, and the profit source of enterprises cannot be guaranteed. In addition, although China has begun to formulate relevant plans to emphasize the development of the industry, the business model is still unclear, mainly showing the business model led by automobile manufacturers. This model has great disadvantages: due to the large number of car brands in China, the target customer groups of different brands of cars are different and relatively fixed, making it difficult to realize the wide application of vehicle information systems. At the same time, each automobile brand independently installs the TSP system, contrary to the requirements of the vehicle network information *** enjoy real-time ****communication.
3, infrastructure lagging behind, information security constraints on the development of the industry
Vehicle Internet is a complex systems engineering, if you want to realize the car and the road, the car and the environment of the interaction, but also need to set up an intelligent traffic signal system, the road side of the information collection unit and other integrated intelligent transportation facilities, however, China's corresponding infrastructure construction compared with the United States, Japan, and Europe, etc., obviously However, the corresponding infrastructure construction in China is obviously lagging behind compared with that in the United States, Japan and Europe. In addition, increasingly stringent network information security laws and regulations, prompting companies to provide vehicle network services pay more attention to information security and cross-border data transmission compliance, it SaaS services and infrastructure providers pose a great challenge.
