1.    OUTLINE

VS-UVSS-1S under vehicle surveillance system is an integrative information management system which can automatically conduct image acquisition, display, contrast and alert for the undercarriage information. The system is highly effective in preventing vehicle undercarriages from hiding bombs, weapons, biologically and chemically dangerous goods and control access to some important sites. It also can prevent the vehicle undercarriages from carrying drugs, smuggling or even to avoid the illegal immigrants from passing the checkpoints.

This system can be widely used in the following places:

Airports, government buildings, prisons, bank depot, military zones,seaports, police
      offices, etc, all of which requires highly secured for anti-terrorism purpose.

Customs, border control

Car park entrance checkpoint to important building

Toll station checkpoints

Checkpoints for entering and exiting vehicles attending conferences

7. Typical Inspection procedures

 

The whole inspection procedure can be programmed, so users can design and configure aux equipment (such as plate recognition camera, scene camera, lane barrier, signal lamp, vehicle sensor, etc) by themselves according to the situation, then program the whole inspection procedure by VSM100, so that kinds of spot needs can be satisfied.

Description:

Drivers should put into inspecting spot when signal lamp is green. First,

“vehicle sensor #1” has detected vehicle passing and trigger “number plate

recognition camera” to photograph and upload the pictures to VSM100, then

recognize plate information, and at this time, “signal lamp” changes into red to prohibit other vehicles entrance, meanwhile, “under vehicle imaging

equipment” is in working status: trigger light turns on; under carriage scanning camera begin to scan and picture is uploaded to VSM100; when “vehicle sensor #2” has detected vehicle tail, trigger light turns off, camera scanning stops, and VSM100 will get the complete pictures displayed on the screen and save it automatically; in the mean time, vehicle is parking in front of the lane barrier, waiting for passing permission, at this time, operator can magnify or compare this picture to rapidly judge whether there is dangerous goods or people. If there is nothing different, the lane barrier will turn on to discharge; after vehicle passing “vehicle sensor #3”, lane barrier automatically drops, “signal lamp” turns green and waiting for the next vehicle coming.
