[ Huaqiang Security Network News ] There are five basic components of the highway monitoring system: 
1. Each highway has a monitoring center building in its managed area. The monitoring center is usually located at the exit and entrance of the expressway, and is also located at the center of the management section. The center is generally equipped with a large map board and a monitoring TV system, and is equipped with a multi-screen switching control device, a video monitor, a low-speed video recording device, and an automatic conversion device. The center is equipped with a computer network system, charge management information for each toll station, control of emergency calls, control of highway entrances and exits and large electronic display screens in the middle, and control of small electronic signboards along the highway. There are also a variety of electronic devices such as a program-controlled switch system, a central console, two or four 8Mbit/s interface optical transceivers, electric terminals and Internet access devices, wireless telephone systems, and UPS power supply systems.
