Safety check flow process:
1, check:
When traffic light system red light, vehicle is parked in line to be checked and waits outward.
While holding sway mouth traffic light system green light, it is current that expression can be accepted vehicle safety check; At this moment vehicle at the uniform velocity sails into design speed per hour, and when feeler A, signal lamp will be converted to red to stop follow-up vehicle to sail into; Trigger testing vehicle register identification simultaneously, testing vehicle register identification can or realize in conjunction with background data base with RFID car plate with the identification of image car plate, after system validation testing vehicle register is correct, will automatically open banister A and license board information is presented on LED screen, otherwise banister A keeps closing.At this moment can be after security staff examines testing vehicle register manually opened banister A.
Legal vehicle continues to remain a constant speed and crosses banister A, when feeler B, will at the bottom of automatic opening vehicle, throw light on and start image scanning at the bottom of car; When vehicle is completely after sensor B, at the bottom of car, scanning will be thrown light at the bottom of will stopping and closing car, system host will show complete car negative film, the standard vehicle base map that simultaneously also Display on the same screen is gone out to this vehicle looks like to contrast, and at the bottom of helping security staff to judge rapidly car, whether keeps foreign matter and carries out repacking; Banister A closes and forbids that follow-up vehicle sails into simultaneously; Vehicle is parked in clearance to be checked district and waits for a green light.
When vehicle safety check, confirm after safety, banister B clearance vehicle is opened in security staff's operation.
When vehicle is completely by after sensor C, banister B falls automatically, and signal lamp is converted to the safety check program that green enters next vehicle.
Scene video camera can be used for whole checking process monitor and record a video, can also be for checking roof and having or not abnormal conditions around.
2, leave the theatre:
When vehicle feeler D, trigger testing vehicle register identification record, after system validation testing vehicle register is correct, will automatically open banister C, otherwise banister C keeps closing.At this moment can be after security staff examines testing vehicle register manually opened banister C.
