[0015] Implementation example
[0016] A detection gantry, a warning gantry and a collision gantry are set up in the upstream of the road height limit section in sequence, such as figure 1 shown. According to the safe passage height of the height-limited road section, according to the national standard of the People's Republic of China GB5768-1999 "Road Traffic Signs and Markings", a height-limiting sign is attached to the gantry at one location. A display with the words "Vehicle Super High" composed of LED dot matrix is attached to the 2 warning gantry. When the ultra-high vehicle passes through a detection gantry, the infrared beam is blocked, Image 6 The middle circuit responded and issued a prompt alarm, and the 2 warning gantry displayed "vehicle high" at the same time. Once the driver cannot stop, the super-high vehicle will hit 3 collision masts and stop.
