Device 1 and RF transmitter 2 may be contained within first supporting rack, 9 top.Overall height detection device is using setting in the first support
The photosensitive sensor 1 and RF transmitter 2 at 9 top of frame carry out the detection of height of car.Specifically, photosensitive sensor 1 and red
The height of outside line transmitter 2 is set according to the height of 6 bottom of limit for height section or height-limiting bar.Photosensitive sensor 1 and infrared ray
Transmitter 2 is respectively arranged at both sides of the road, when the vehicle for having more than preset height passes through photosensitive sensor 1 and RF transmitter
When between 2, connection optical signal between photosensitive sensor 1 and RF transmitter 2 is cut off, and photosensitive sensor 1 is by optical signal
Variable signal be sent to PLC.
Further, the photosensitive sensor 1 and RF transmitter 2 are detachably connected with the first supporting rack 9.It is photosensitive
Sensor 1 and RF transmitter 2 are detachably connected with the first supporting rack 9, can be by adjusting photosensitive sensor 1 and infrared ray
The height of transmitter 2 makes overall height detection device adapt to the limit for height section of different height.Also, when photosensitive sensor 1, infrared ray
When transmitter 2 or the first supporting rack 9 are damaged, it is only necessary to it replaces wherein broken parts and can be used continuously, it is cost-effective.
Further, the alarm mechanism includes buzzer 4 and alarm lamp 5, and the signal output end of the PLC is separately connected
The signal input part of the buzzer 4 and alarm lamp 5.Alarm mechanism includes 5 two parts of buzzer 4 and alarm lamp, alarming machine
The light two ways that the sound and alarm lamp 5 that structure can be sent out by buzzer 4 are sent out warns driver, and raising is driven
The person of sailing is to superelevation violation alarm signal note that effective the case where avoiding driver from ignoring because of alarm signal unobvious.Bee
The signal output end of the signal input part and PLC of ring device 4 and alarm lamp 5 connects, when the optical signal that photosensitive sensor 1 receives occurs
When variation, photosensitive sensor 1 sends signal to PLC, and PLC control buzzers 4 and alarm lamp 5 send out alarm, to driver into
Row warning.
Further, the indication mechanism further includes the second supporting rack 10, and use is additionally provided in the bottom of the display panel 7
In detection vehicle by vehicle by inductor 8, the vehicle connects the PLC's by the signal output end of inductor 8
Signal input part.Display panel 7 is set to the top of the second supporting rack 10, and is kept making at a distance from vehicle safety passes through with ground.
Display panel 7 is for showing the information such as the license plate number of Overheight Vehicles.The bottom of display panel 7 is additionally provided with to be passed through for detecting vehicle
Vehicle by inductor 8, vehicle connects the signal input part of the PLC by the signal output end of inductor 8.Vehicle passes through
Inductor 8 for detect Overheight Vehicles whether the lower section by vehicle by inductor 8, when Overheight Vehicles pass through sense by vehicle
After answering device 8, vehicle sends signal to PLC by inductor 8, and PLC controls the display panel 7 and no longer highlights the Overheight Vehicles
License plate number, and aobvious protrusion is shown to the license plate number of next Overheight Vehicles.
Further, the display panel 7 is equipped with license plate number viewing area and the use of the license plate number for showing Overheight Vehicles
Road instruction area in instruction detour section direction.Display panel 7 divides for license plate number viewing area and road instruction area, Overheight Vehicles
Driver the vehicle of driving superelevation can be explicitly observed by the license plate number viewing area on display panel 7.If
Driving vehicle is Overheight Vehicles, and the road instruction area of display panel 7 would indicate that bypass route direction or rest area direction, is driven
Member can be detoured by the instruction in road instruction area or carry out the adjustment of height of car in rest area, and front limit is avoided collision
High section, the generation to try to forestall traffic accidents.The license plate number viewing area of display panel 7 can show the license plate number of multiple Overheight Vehicles,
And highlight the license plate number of the Overheight Vehicles nearest apart from indication mechanism, increase warning of the driver to vehicle superelevation
Effect.
The above is only the preferred embodiment of the utility model only, is not intended to limit the utility model, all at this
All any modification, equivalent and improvement etc., should be included in the utility model made by within the spirit and principle of utility model
Protection domain within.
