The utility model discloses a suitcase include the box and with one side of box is rotated and is connected, but and the upper cover of opposite side lock, the upper cover is embedded to have the panel computer, the box is embedded to have the magneto -optic to detect host computer and storage tank. The utility model discloses a magneto -optic monitoring suitcase passes through scanning metal surface's magnetic field information, determines and confirm ferromagnetism metal surface's defect, because magnetic field does not receive the influence of dust, paint, consequently can realize can't harm surveying, for example can be applied to the discovery polish the vestige, number and mark etc. Recover to can satisfy the requirement of policeman on -site working.
Description
Technical field
The utility model relates to the technical field that cracks of metal surface detects, and more particularly, the utility model relates to a kind of magneto-optic and detects suitcase.
Background technology
The defect that metal surface is trickle, as cut, weld mark, hole etc., if covered by dust paint etc., user is just difficult to find.Present inventor provides a kind of nondestructive testing instrument for this reason, and this instrument by the Magnetic Field of scanning metal surface, thus judges the defect on ferromagnetic metal surface.Because metal surface is uneven, cannot directly scan its magnetic field, therefore this instrument covers metal surface by soft magnetic stripe, then more uniform magnetic field is added by magnet, the magnetic line of force can enter metal through magnetic stripe, the concavo-convex grade on its surface can have influence on magnetic field, thus causes the magnetic field of magnetic stripe recording just to reflect the concavo-convex situation on surface.But because magnetic stripe magnetic field is invisible to naked eyes, for this reason, also need a kind of equipment to carry out imaging to magnetic stripe magnetic field.
Utility model content
In order to solve the technical matters existed in prior art, the purpose of this utility model is to provide a kind of magneto-optic completing the imaging of magnetic stripe magnetic field simply, leggiero to detect suitcase.
In order to realize above-mentioned utility model object of the present utility model, the utility model provides following technical scheme:
A kind of magneto-optic detects suitcase, it is characterized in that: described suitcase comprises casing, and is rotationally connected with the side of described casing, and the upper cover that opposite side can fasten; Described upper cover is embedded with panel computer, and described casing is embedded with magneto-optic and detects main frame and storage tank; And described magneto-optic detects main frame comprises magnetic stripe travel mechanism, described magnetic stripe travel mechanism comprises magnetic stripe entrance and magnetic stripe outlet, between described magnetic stripe entrance and magnetic stripe outlet, have magnetic stripe mobile route; Above described mobile route, be provided with pressing plate, below described mobile route and in the face of the position of described pressing plate, be provided with magneto-optic film, the below of magneto-optic film is provided with light splitting piece, polarized light source and camera; For controlling the single-chip microcomputer of described polarized light source, magnetic stripe travel mechanism and camera.
Wherein, described magneto-optic detects on main frame and has the USB interface be connected with described panel computer.
Wherein, described magneto-optic detects on main frame also has LED state pilot lamp, and battery electric quantity pilot lamp.
Wherein, described polarized light source is made up of planar light source and linear polarizer.
Wherein, described camera is CMOS camera, and is provided with linear polarizer between described light splitting piece and described CMOS camera.
