1.Compared with other detection techniques, it is no doubt that laser detection for over-high vehicle is more precise and reliable.
2.When the vehicle height is over the height set in advance, the laser detection equipment will issue order to the alarming LED display in front which will warn the driver of over-high vehicle (sound-light alarm) and guide vehicle to bypass by providing safe drive route.
3.If the over-high vehicle continues running, this system will trigger video snapshot system to snapshot pictures thereof or trigger video recorder to record the same and transmit the pictures or videos to the computer on duty in monitoring center. Accordingly, the monitoring personnel can identify the license number from the pictures or videos clearly to benefit the management department to conduct violation evidence collection.
Laser over-high vehicle detection guidance alarming system is divided into three parts:
1. Laser detection- precisely detect over-high vehicle in manner of laser bijection detection
2. Guidance alarming- guide over-high vehicle to safe drive route by LED display
3. Video snapshot- detect and snapshot pictures or record videos for over-high vehicle driven in bridge route.
4. Information management- manage the pictures and information uploaded of over-high vehicle uniformly and rationally.
