Safety Check System Under Car/Traffic Barrier/Barrier Gate

 

 
The vehicle imaging device and ground sensing coil are embedded in the middle of the vehicle access channel, and the license plate recognition camera and intelligent control box are fixed in the appropriate position in front of the embedded device.
After the security personnel confirm the vehicle, the traffic light lights up, the road gate opens, the vehicle triggers the ground sensing coil (automatically turn on the LED auxiliary light source, automatically trigger the license plate recognition), and continuously passes through the scanning imaging equipment (equipment scanning and saving records), the vehicle is parked in the waiting area, after the security personnel verify the vehicle and the driver is correct, the vehicle stopper is closed and the green light is on. The vehicle is cleared. After that, turn on the brake and wait for the next vehicle.
 

 

The hardware parts of the underbody safety inspection equipment include the following:

system host platform;
Car underbody imaging equipment;
ground sensing coil;
Intelligent control box;
License plate recognition camera.


 

 

The host platform of the system is mainly used to run the upper computer software, receive the images of the car bottom and license plate through network communication, and then process, analyze and store them.


 

 

Underbody imaging equipment is the key equipment in the underbody safety inspection system, which is used to complete the data acquisition of the vehicle chassis image and facilitate the computer to process the image. The system adopts the most advanced color digital linear array imaging technology, which can realize the complete scanning imaging of the car bottom at one time without omission. However, the imaging equipment under the car is an outdoor installation equipment, and the environmental adaptability of the component is the key to determine whether the whole system can work stably for a long time. Under the car imaging equipment adopts advanced modular design, with good environmental adaptability, its component box, movement, LED surface light source and other important parts are using special compression protection anti-vibration seal design, the entire equipment closed installation, well meet the user's waterproof, moisture-proof, dust-proof, anti-fog and other performance requirements. Under the car imaging equipment has excellent stability and reliability, can work normally for a long time in any natural environment, and truly achieve all-weather and maintenance-free use needs for users.

With reference to the world's leading underwater detectors, submarines, aviation equipment and other fields of advanced technology design, the use of professional equipment, including movement, LED surface light source, image acquisition equipment, etc., are respectively using high-strength sealed anti-vibration separate design, the components involved are all using mature spherical seal design technology. Thus, it solves the technical requirements of different users on waterproof, moisture-proof, dustproof, salt spray and fog prevention. Its design diagram is shown in the figure.

 

 

To reduce the deformation caused by rolling of equipment, we refer to the user requirements of airports, prisons, borders and other users, designed the special anti-rolling protective cover for the car bottom products, the use of high-strength special materials to make durable, this series of special protective cover can provide a variety of technical solutions to meet different user choices (can provide for more than 20 tons of vehicles rolling technical requirements). Installation area can be flexibly designed according to user needs.


 

 

Under the car lighting system uses a special high-power LED surface light source design, this kind of under the car image special light source has high brightness, good stability, microsecond response time, more uniform lighting effect, multi-light source scientific combination, to ensure the best under the car lighting effect, the design can greatly reduce the dependence on the vehicle standard driving.

The low voltage DC 24V power supply ensures the safety of the equipment and greatly improves the service life and stability of the system.

Under the car image acquisition device, movement, high-performance LED surface light source and other anti-rolling protective covers are designed with special optical spherical superhard materials, using surface self-cleaning technology, thus greatly reducing the dependence of equipment on environmental adaptability.


Intelligent control box

Intelligent control box mainly includes distribution cabinet and internal corresponding products, auxiliary lighting control: DC24V; System power supply: AC220V/50-60Hz/500W. Including vehicle detection equipment and trigger signal receiving equipment, trigger and control signal linkage with equipment. Working voltage: AC110-240V 50/60Hz, working current: 3A, working temperature: -20ºC ~ 55ºC.



License plate recognition camera

License plate recognition camera adopts 1/3 "CCD sensor and SONY digital DSP signal processing technology, with 4 million high-definition pixels, high sensitivity performance; The intensity of the auxiliary light source can be adjusted continuously through the potentiometer VR of the control board in the body; Strong light suppression (halo shrinkage) can be adjusted through the control board OSD MENU button into the main menu, debugging mode is more simplified; The use of special light sources to fill the light, at night can also show the full color license plate.
