With the development of information technology, the industrialization trend of Internet of things has gradually taken shape and has been widely used in various fields of agriculture, industry and commercial services, which has had a significant impact on people's production and life. At present, Internet of things technology has been applied in highway construction, which has promoted the information and intelligent development of highway industry.
At present, Internet of things technology has been widely used in intelligent transportation, environmental protection, government work, smart grid, smart home, public safety, environmental monitoring, positioning and tracking, elderly care, flower cultivation and other fields, and shows incomparable advantages.
Necessity of Internet of things technology application in smart highway construction
At present, in the process of rapid development of expressway construction in China, some problems have also been exposed, which are mainly reflected in the difficulty of fault location, low processing efficiency, opaque process and so on. Based on this, we must make full use of IOT technology to realize the mobile management of highway operation and maintenance, visually monitor its operation status, comprehensively optimize the highway operation and maintenance management and realize the intelligent operation and maintenance of the highway.
The Internet of things is an important part of the new generation of information technology. The IT industry is also called pan Internet, which means that things are connected and everything is connected. Thus, "the Internet of things is the Internet connected with things". This has two meanings: first, the core and foundation of the Internet of things is still the Internet, which is an extended and expanded network based on the Internet; Second, its client extends and extends to any goods and goods for information exchange and communication. Therefore, the Internet of things is defined as a network that connects any item to the Internet for information exchange and communication through information sensing devices such as radio frequency identification, infrared sensor, global positioning system and laser scanner according to the agreed protocol, so as to realize the intelligent identification, positioning, tracking, monitoring and management of items, So what are the specific applications of the Internet of things in the highway system?
1. Application of Internet of things technology in highway traffic guidance system
The expressway traffic guidance system mainly relies on the basic information collected by the basic information platform, such as the current natural state of traffic facilities, construction, design, use and maintenance archives, environmental conditions, weather conditions and other information, automatically detects the operation state of the highway, and carries out early warning and response according to the monitoring results. In highway transportation, the highway traffic guidance system can effectively detect the traffic operation of the highway in real time through the Internet of things technology, effectively analyze the characteristics of traffic operation through the collected data, and then scientifically predict the traffic flow of the whole highway, and formulate the best emergency measures and emergency plans on this basis; Through the application of Internet of things technology in highway traffic guidance system, radio frequency identification technology and sensor technology can be used to guide vehicles and fleets, so as to achieve the purpose of traffic guidance.
2. Application of Internet of things technology in rescue system
In highway traffic, once a traffic accident occurs, rescue workers must rush to the accident phenomenon at the first time. At this time, the highway rescue system can effectively monitor the location of traffic accidents and the number of injured people through the Internet of things technology, and then realize the intellectualization, visualization and flattening of highway network traffic through the information and functions of traffic control, emergency support and data service system according to the monitoring results, Then improve the normal control ability of the highway and the ability to deal with emergencies, so as to further ensure the smoothness of the highway.
3. Application of Internet of things technology in vehicle identification and vehicle monitoring system
In the operation of the highway, it has a certain "big data" analysis ability. On this basis, it can be better managed through the Internet of things technology. Among them, vehicle identification system is one of its core businesses. Through the Internet of things technology, the vehicle identification system can effectively identify all running vehicles and parked vehicles in the highway. At the same time, the system can also effectively perceive the vehicle speed, vehicle distance and other information, and effectively connect it with the electronic license plate information to play a role together, so as to realize the effective monitoring of vehicles on the road.
4. Application of Internet of things technology in electronic toll collection system
The electronic toll collection system (etc) makes full use of the information technology of the Internet of things. Through the special short-range communication between the road test antenna and the on-board electronic tag, the driver can charge without stopping. The specific application of Internet of things technology in the system is to effectively record various information of vehicles through electronic labels installed on vehicles and various outfield equipment, transmit the recorded information in real time and transmit it to the toll station management system. After the toll station management system obtains the corresponding data information, it carries out transaction, account dismantling and financial settlement according to the corresponding standards, and then completes the collection and processing of various data and images in the system.
