Specific embodiment
Referring to Fig. 1 to Fig. 9, vehicle mounted GPS guidance system 1 is opened when vehicle driver sets out, inputs the maximum height of vehicle
Or the maximum height of loading, the two height take large values, then input destination, vehicle mounted GPS guidance system 1 show approach bridge and
The headroom in tunnel, if vehicle super-high, vehicle mounted GPS guidance system 1 alert driver's vehicle by some bridge or
Tunnel superelevation reminds driver to detour, and when Overheight Vehicles close on bridge or tunnel, alerts driver's vehicle again and has surpassed
Height, no through traffic, if driver drives Overheight Vehicles and continues to move ahead, when Overheight Vehicles are travelled to 2 He of license plate number identifying system
When the location of laser elevation scanning system 3, the laser emitter 23 of laser elevation scanning system 3 emits laser beam scanning
It is reflected back laser elevation scanning system 3 to the superelevation part of Overheight Vehicles, and by reflection light, thus judges the vehicle super-high simultaneously
Signal is transmitted to microprocessor, while license plate number identifying system 2 identifies the license plate number of the vehicle and signal is transmitted to microprocessor,
Microprocessor starts sound equipment light warning device after receiving superelevation information and the license plate number of vehicle, has alerted the vehicle of the license plate number
No through traffic for superelevation, if Overheight Vehicles continue to move ahead, when Overheight Vehicles are travelled to the position of rotary switch device 24, and superelevation
The whippletree 26 that rotary switch device 24 is hit in the superelevation part of vehicle rotates, and the rotation of whippletree 26 pushes basculating arm 28 to rotate, basculating arm
Switch 27 is closed a floodgate in 28 rotation connects the power supply of a pair of of electromagnet 10 of vehicle arresting system 4, and a pair of of electromagnet 10 is powered will
A pair of of movable lug 21 retracts, and the plate 15 of ground thorn device 6 loses constraint, and the elongation of spring B 11 pushes up ground thorn device 6 upwards, works as cross
When two chamferings of 13 upper end of beam encounter the inclined surface of a pair of of backstop tongue 7, crossbeam 13 pushes a pair of of backstop tongue 7 respectively retraction, left
The two spring A8 in the right side respectively compress, and after crossbeam 13 crosses the inclined surface of a pair of of backstop tongue 7, the spring A8 of left and right two is respectively returned again
Bullet elongation, a pair of of backstop tongue 7 is released, and a pair of of backstop tongue 7 of release withstands the lower part of the left and right ends of crossbeam 13, prevents ground thorn
Device 6 moves down, and thorn cone 12 on the wheel tire pressure of Overheight Vehicles, tire is punctured, and Overheight Vehicles will stop by force.It needs to illustrate:
There is no the headrooms in storage bridge perhaps tunnel can not manually enter vehicle (or loading) for current GPS navigator
Maximum height, also the maximum height of the headroom in bridge or tunnel and vehicle (or loading) is not compared simultaneously
The function of judgement, vehicle mounted GPS guidance system 1 of the invention all have above-mentioned function.
