In recent years, China's transportation industry has developed rapidly, and the national highway mileage has been increasing year by year. At the same time, the phenomenon of exceeding limits and overloading is becoming increasingly severe, bringing serious harm to people's travel and social safety.
"Non on-site law enforcement" is a necessary supplement and extension of traditional on-site law enforcement. It is not affected by geographical location, time, and weather. Even in places without the supervision of law enforcement personnel, remote real-time monitoring can still be achieved, enabling more comprehensive and efficient law enforcement. By utilizing technological means, administrative law enforcement work can become more scientific and intelligent, effectively alleviating the problem of insufficient law enforcement capabilities, while also reducing contradictions and conflicts in law enforcement practice and improving the law enforcement environment.
At present, the non on-site law enforcement detection solutions in China have similar technical routes, mostly based on vehicle information collection, consisting of several components such as non-stop weighing subsystem, external dimension detection subsystem, license plate recognition and capture subsystem, video monitoring subsystem, and information release subsystem.

Lidar, as a new type of ranging technology, plays an important role in the external contour size detection subsystem. Compact, accurate, stable, and low-power, with these advantages, LiDAR has been integrated into essential products for road overload detection facilities.

The laser vehicle length, width, and height detection system under Intelly Technology adopts high-precision LiDAR detection equipment, which real-time and accurately detects vehicle size information to check whether it exceeds the limit. Once an oversized vehicle is found, it will be immediately fed back to the backend data system to promptly stop oversized behavior. In addition, the system does not need to damage the ground, and can be used simply by installing upright poles or installing them on the gantry, greatly reducing the number of equipment deployments and engineering workload, reducing equipment failure rates and maintenance difficulties in the later stage.
