The security check and protection system of highways needs to integrate intelligent monitoring, vehicle security check, and perimeter protection technology. The core equipment configuration is as follows:
I. Intelligent monitoring system
ETC gantry equipment
Integrate license plate recognition and real-time billing functions, and deploy gantry gateways to ensure data transmission security.
Multi type detector
Meteorological detector: monitoring wind speed, temperature and humidity, visibility, and road conditions;
Traffic flow detector: Microwave/video detection for real-time traffic density.
Intelligence board system
The gantry style variable information screen remotely issues road condition warnings and links traffic guidance strategies.
II. Vehicle security inspection equipment
Vehicle bottom scanning system
Fixed vehicle bottom scanner: capable of carrying 50 tons, supporting bidirectional speed measurement and panoramic image capture, linked license plate recognition and barrier control;
Mobile scanning mirror: Portable deployment, quick detection of hidden objects on vehicle chassis without construction.
Anti collision facilities
The hydraulic lifting column intercepts malicious vehicles and has an impact resistance of ≥ 7.5 tons.
III. Perimeter and unmanned protection
Electronic fence system
Pulse fences cover tunnels and key road sections, triggering alarms and synchronously positioning video surveillance.
Explosion proof monitoring equipment
Infrared high-speed ball camera: all-weather monitoring of tunnel ventilation and lighting system, supporting smoke and fire recognition and low light imaging;
Wireless interference monitoring vehicle: locates electromagnetic interference sources in the 30MHz-3000MHz frequency band with an accuracy of up to 5 meters.
IV. Technical specifications for key equipment
Equipment type, functional requirements, technical standards
ETC gantry gateway toll network data encryption transmission complies with GB/T 22239-2019 level protection
Information board remote information release IP66 protection, lightning protection design
The vehicle bottom scanner supports 10 ton level mobile detection output IO signal linkage with barrier gates
Tunnel environmental detector monitors CO concentration and visibility explosion-proof certification (Ex d IIC T6)
Deployment specifications:
Unmanned equipment needs to pass electromagnetic compatibility testing (30MHz-3000MHz);
Surveillance video storage for ≥ 90 days, perimeter alarm response time ≤ 8 seconds.
Technology trend:
The new generation of system integration BIM operation and maintenance platform realizes real-time monitoring of equipment status and fault warning, reducing the leakage rate of dangerous goods to 0.03%.
