The utility model provides a technical scheme that its technical problem adopted is: a desk type motor vehicle license plate detection device comprises a detection machine arranged on a workbench and an industrial personal computer connected with the detection machine; the detection machine comprises a rack, wherein an imaging module connected with an industrial personal computer is fixedly arranged at the upper part of the rack, and a test seat is arranged below the imaging module; the bottom of the rack is provided with a bottom plate, and a trigger sensor is arranged on the bottom plate; when the motor vehicle license plate that awaits measuring is placed on the test seat, trigger sensor output detection instruction, the formation of image module to the motor vehicle license plate that awaits measuring detect of shooing.

Further say, the imaging module include camera, camera lens and light source, the light source include first light source and second light source, first light source set up in the top of second light source.

Still further say, first light source be annular light source, the second light source be symmetrical bar light source.

Furthermore, the test seat of the utility model consists of two mutually perpendicular limit stops.

Furthermore, the trigger sensor of the utility model is a proximity switch.

Furthermore, the utility model discloses still include OK article display lamp, NG article display lamp and the bee calling organ be connected with the industrial computer.

Further, the utility model discloses still include keyboard and the display of being connected with the industrial computer.

Further say, the outside cover of frame be equipped with the protection casing, the position that the protection casing corresponds the test seat is provided with the opening.

The utility model has the advantages that the defects in the background technology are solved, the manual detection operation is replaced by the instrument detection and judgment, the number plate collection and verification can be more quickly and accurately carried out, and a large amount of manpower and slow detection and verification speed are reduced; meanwhile, the problems that manual inspection inevitably causes errors, license plate collection errors and the like are avoided, the productivity is increased, and the errors are reduced.
