As a new technology that integrates wireless communication technology, microelectronic sensors, and embedded systems, the Internet of Things is gradually being used in intelligent transportation systems and other related fields that require data collection and detection, thereby bringing a new upgrade to urban intelligent transportation.
The existing urban traffic management is basically carried out spontaneously, and the traffic signal signs only play a static and limited guiding role. This has led to the failure of the most efficient use of urban road resources, and the intelligent urban transportation infrastructure can collect vehicle and road information in the entire city in real time, and dynamically calculate the optimal traffic command plan and vehicle through intelligence. Line route. According to expert research, after adopting intelligent transportation technology to improve the level of road management, the number of deaths in traffic accidents can be reduced by more than 30% each year, and the use efficiency of transportation can be improved by more than 50%.
Beijing has always been known as the “first congestion”, but in recent years, with the upgrading of the intelligent transportation system and the improvement of road planning, Beijing’s transportation has been greatly improved.
Beijing’s historical cultural relics account for about 42% of the area of the old city. Roads cannot be widened indefinitely. Intelligent public transportation is the best choice to improve transportation. The Internet of Things and RFID technology have become the development trend of intelligent transportation. It is understood that at present, induction coils are buried in all main streets of Beijing. As long as a vehicle passes by, the coils will have electromagnetic induction, and this information will be conveyed to the computer system. The computer performs real-time timing of the traffic lights based on the traffic flow in both directions. .
In terms of information collection of driving vehicles, Beijing extensively uses non-contact geomagnetic sensors to regularly collect and perceive information such as the speed and distance of vehicles in the area, and provide intelligent management for the monitoring and diversion of traffic flow. When the vehicle enters the monitoring range of the sensor, the terminal node collects important information such as the driving speed of the vehicle through the magnetic sensor, and transmits the information to the next node that wakes up regularly. Multiple terminal nodes gather the information collected and preliminarily processed respectively to the gateway node through the convergence node to obtain information such as road traffic flow and vehicle speed, so as to provide accurate input information for intersection traffic signal control.
In addition, by installing various sensors such as temperature and humidity, illuminance, and gas detection on the terminal nodes, it is also possible to detect road conditions, visibility, and vehicle exhaust pollution.
Of course, the Internet of Things technology can also be widely used in special vehicles such as taxis, police cars, and ambulances. For example, installing RFID tags on taxis will realize real-time monitoring of automobile fuel consumption and mechanical parts to ensure safe driving. The Internet of Things technology can also be used to achieve video surgery and so on. The electronic tags mounted on the vehicles can extract and effectively use the attribute information and static and dynamic information of all vehicles on the information network platform through the use of radio frequency and other identification technologies, and carry out the operation status of all vehicles according to different functional requirements. Effective supervision and provision of comprehensive services.
The automotive digital standard source technology is an application technology of car-related information resources developed based on RFID. The project was developed by the Ministry of Public Security and was certified by the Ministry of Science and Technology as a key special project of the 2007 “National Science and Technology Support Plan”. Application demonstration project (project number is 2008BAF31B00). The development of automotive digital standard source technology will advance the process of “Internet of Vehicles” and RFID industrialization.Based on the above, we can summarize the car and the Internet of Things into three major sectors

The development and application of the Internet of Things in transportation
Looking at the current situation, when a traffic emergency occurs, vehicles and pedestrians cannot be the first to grasp the situation of the incident and the situation on the spot. Unable to start the emergency plan to dispatch the personnel, vehicles and materials needed for emergency repairs, and complete the emergency handling in the shortest time. Therefore, the application of the Internet of Things will implement three important supervisions on urban traffic:
1. Realize the full tracking and traceability of public transportation, ensure the safety of transportation, and finally realize the government’s digital dispatch management and the optimization of urban transportation resources.
2. Realize the accurate identification of important equipment such as urban public transportation and rail transit, realize the transparency of management, and provide a legal basis for transportation safety and ensuring the safety of transportation facilities and equipment.
3. Realize the tracking of vehicles and trains throughout the operation, improve the ability and level of accident prevention and control, enhance real-time dispatch monitoring and emergency incident handling capabilities, and promote the sustainable and healthy development of transportation.
As an important part of the new generation of emerging industry information technology, the Internet of Things will become a trillion-level emerging industry in the global information and communication industry. It will use radio frequency identification (RFID), infrared sensors, global positioning systems, laser scanners and other information sensing The equipment, according to the agreed protocol, connects any object to the Internet for information exchange and communication to realize the intelligent identification, positioning, tracking, monitoring and management of objects.
It is realizing the leap from local to interconnection, and enterprise applications from the Internet to the Internet of Things, thereby promoting my country’s Internet of Things industry from technical concepts to daily public application services. It is becoming the third wave of the world’s information industry after computers and the Internet. .
From the concept of the Internet of Things to the development of the Internet of Things in various industries today, the Internet of Things has entered a stage of rapid development from the early market cultivation period. The proposal and application of intelligent transportation and other solutions are also becoming more mature. The establishment of the later standardization system and breakthroughs in core technologies of independent intellectual property rights will bring a broader market space for transportation.
The future development of the automobile industry must be smart and environmentally friendly, and the development of the Internet of Things is injecting a new technological method into the automobile industry while promoting the intelligentization of automobiles. The increase in the number of automobiles is also destroying things to a certain extent. The more complete networking is also predicting that his arrival is an inevitable trend of social development.
