1. Project background
Intelligent Transportation System (Intelligent Transportation System, referred to as ITS) is the development direction of the future transportation system. It effectively integrates advanced information technology, data communication transmission technology, electronic sensing technology, control technology and computer technology for the entire ground transportation management A real-time, accurate, and efficient comprehensive transportation management system that is systematically established and works in a wide range and omni-directional manner. ITS can effectively use existing transportation facilities, reduce traffic load and environmental pollution, ensure traffic safety, and improve transportation efficiency. Therefore, it has received increasing attention from various countries. As a professional provider of solutions for the Internet of Things industry, Shenzhen Hongdian has many successful applications in the field of intelligent transportation, such as vehicle-mounted wireless dispatching and monitoring systems, smart parking lots, and electronic police. This article mainly introduces the automatic vehicle detection networking system that Shenzhen Hongdian cooperated with a company in Wuhan to promote and apply across the country. Through this system, the traffic management department can obtain vehicle speed, vehicle flow, license plate information, etc. in real time, which is convenient for traffic management and dispatching by the traffic law enforcement department. , Investigation and tracking of illegal vehicles, and intelligent traffic management are another successful application of the Internet of Things technology in the field of intelligent transportation.
2. Project plan
The automatic vehicle detection system constructed by the project using sensor technology, video technology, and wireless communication technology is mainly composed of three parts. The front end is the collection terminal, which mainly includes three types of equipment: The main function of the high-definition infrared capture camera is to capture license plate information, monitoring of illegal driving behavior in the car, etc. The traffic flow detector performs statistical monitoring of the traffic flow of the road section through the ground sensing coil, and the other is the vehicle The speedometer measures the speed of passing vehicles. The three devices collected at the front end have been connected to Shenzhen Hongdian’s wireless 3G router, and the data is transmitted in real time to the back-end traffic control department database and business management workstation through the 3G wireless network, so that the traffic control department can timely monitor and dispatch the traffic on the spot.
3. Product features
The Shenzhen Hongdian H7920 industrial 3G wireless router used in this project adopts industrial-grade embedded wireless network modules, supports APN and VPDN wireless private networks, supports online maintenance of equipment; supports ADSL (PPPoE) dial-up, fixed IP and DHCP clients Internet access and DHCP service functions; support DNS proxy and DDNS service functions; support network address translation NAT and DMZ functions, support VPN private networks; support network system upgrade functions; support configuration file recovery and backup functions, support false connection link detection, The wireless communication function in this project is perfectly guaranteed.
4. Project significance and scale
Intelligent transportation is the hotspot and frontier of the development of transportation in the world today. It relies on existing transportation infrastructure and vehicles to build safe, convenient, efficient and green transportation through the integrated application of modern information, communication, control and other technologies. The system is the goal to fully meet the diversified needs of public travel and cargo transportation, which is an important symbol of the modern transportation industry. The application of the automatic vehicle detection system realizes the monitoring of vehicle information such as license plate, vehicle flow, and vehicle speed, and provides accurate and real-time information for vehicle scheduling, vehicle flow management, and traffic supervision. The automatic vehicle detection project is applied to many cities and regions across the country. As a communication system provider, our company has provided more than one thousand sets of H79203G router equipment, which reduces the cost of wiring and construction inconvenience caused by wired communication, and provides reliable, stable, and real-time data transmission service guarantee for the system.
