To build a strong transportation country, we must take Socialism with Chinese characteristics Thought in the new era as the guide, implement the new development concept, take the supply-side structural reform as the main line, and take innovation as the guide to comprehensively promote the quality change, efficiency change and power change of transportation development. And the internet of things is the strong agent that this era brings to the development of transportation.
1. How should the Internet of Things transform traffic?
Architecture of 1 Intelligent Transportation System Based on Internet of Things
Intelligent transportation system based on Internet of Things must fully consider all kinds of infrastructure and traffic objects.
Only by constructing the perception network of basic traffic can we develop various types of intelligent management service systems. This brand-new concept will fundamentally change the transportation system, only pay attention to the business development model, and turn to the direction of enjoying the demand for information resources. To truly apply the Internet of Things to the field of intelligent transportation, we must first build an intelligent transportation system architecture under the Internet of Things environment.
This intelligent transportation architecture based on Internet of Things is mainly composed of perception layer, network layer and application layer.
1. 1 perception layer
The sensing layer of the intelligent transportation system of the Internet of Things is mainly responsible for collecting all kinds of traffic information accurately. In particular, the perception of various traffic information should be realized through the network and sensors. The collection process of sensors must be completely transmitted by wireless sensor networks in order to achieve good data aggregation.
1.2 application layer
The main function of application layer is to collect data from traffic perception network, and further analyze and apply data information to support various intelligent transportation services. Application systems are mainly divided into government application systems, social application systems and inter-enterprise demonstration systems.
Among them, the most typical application systems mainly include traffic control system and dynamic control system. In order to realize the integration of intelligent wireless sensor and telecommunication network sensor, wireless sensor network must be connected to telecommunication network. Using telecommunication network to further realize the monitoring and management of various services in wireless sensor networks.
1.3 service platform
Business platform is a business entity that promotes the operation and management of telecommunication network, and also integrates with wireless network sensors, and coordinates other entities in telecommunication network to complete the whole business system.
The management platform, as an entity platform for the telecommunication network to manage the wireless sensor network, mainly aims at managing the equipment and network of the business platform. At the same time, in order to ensure the more reliable operation of the telecommunication network, it is necessary to introduce an effective control mechanism between the telecommunication network and the wireless flow sensor.
This access control mechanism means that the telecommunications network uses the gateway system to effectively control the control points and provide overall services for the wireless sensor network.
2. The influence of Internet of Things technology on ITS.
Because the Internet of Things has mature technical advantages in electronic communication and computer technology, the effective combination of Internet of Things technology and intelligent transportation system can provide a brand-new development idea for China's transportation industry.
The Internet of Things is the third wave of information industry after computer and Internet technology, which gave birth to a network system that changed the production and sales of products. At the same time, the new concept put forward by the Internet of Things has a far-reaching impact on human life style. So far, in the transportation and logistics industries, the Internet of Things technology has gradually become popular.
2. 1 Perceptual information
The core content of the Internet of Things is the information and data in the transmission process. First, to identify the attributes of objects, including static and dynamic. It is also necessary to read the attributes of the object through certain equipment and convert the information into an important data for network transmission.
2.2 Collecting information
On the one hand, it is necessary to collect a lot of traffic information and collect and process real-time information to build an intelligent transportation system under the Internet of Things environment. On the other hand, we should pay more attention to the effective integration and transmission of information resources.
Because the intelligent transportation system takes the expressway as the technical exchange platform, it must be based on traffic information, promote the connection between people's traffic trips and vehicles, and improve the safety and efficiency of the transportation system.
Therefore, as long as the traffic system is based on advanced traffic information, it can provide various traffic information service systems for other traffic travelers and promote the rational layout of traffic.
2.3 Application of information
If an object wants to transmit effective information, there are two main application directions: one is to transmit it to "people" through centralized and effective processing of the object, and then to further control it through advanced processing of "people".
On the other hand, it is a reasonable and intelligent control of "things" directly, and power can be granted without "people". Through the in-depth analysis of the overall operation of the Internet, the reasonable interaction of information between things and people can be realized.
Therefore, this kind of "thing" is likely to involve the existence of concrete entities in the material world, including the concrete entity attributes of people.
In particular, all activities of the Internet of Things are based on people's wishes. At the same time, the network standard is the ultimate factor to realize the operating environment of the Internet of Things, which provides effective and reasonable environmental support for intelligent transportation informatization.
Second, the application example
1, Internet of Things technology realizes intelligent analysis and judgment of drivers' bad driving behavior.
G7 Company adopts mature technical means to realize data acquisition and artificial intelligence identification of position, sound and image through Internet of Things technology. ?
"At present, our company has been able to monitor and manage the dangerous behavior of drivers in real time. When the driver has dangerous behaviors such as dozing off and playing mobile phones, the vehicle terminal will give the driver an alarm, and can also inform the administrator of cloud monitoring. The fleet administrator can also send voice messages to remind the driver. " The president of the company introduced, "At the same time, the images collected in real time can also be used as evidence afterwards to conduct safety education and management for drivers and effectively reduce the accident rate. One customer used it for three months, and the accident rate per million kilometers dropped to one-third of the previous one. "
2. ZTE Intelligent Transportation System
