Abstract
The invention discloses an RFID integral reader-writer based on a gap area. The reader-writer comprises a shell, an emitter, a fixed shielding plate, two rotary shafts, a movable shielding plate and a folding sector-shaped shielding plate, wherein the shell is a box with an unsealed bottom, and the distance between two opposite side plates of the box is not larger than the width of a gap; the emitter is arranged in the box; the fixed shielding plate is fixedly connected with the lower end faces of the two opposite side plates of the box; the two rotary shafts are installed on the lower end faces of the other two opposite side plates of the box; the movable shielding plate is connected with the two rotary shafts in a pivot mode; the folding sector-shaped shielding plate is formed by connecting multiple sector-shaped shielding plate bodies through a folding rotary shaft, and the fixed shielding plate, the movable shielding plate and the folding sector-shaped shielding plate form a sealed space. By means of the structure, the structure of a traditional RFID reader-writer is improved, a read-write area can be controlled, the reader-writer is suitable for scenes of the gap area, and a manager can obtain labels, needing to be read, in a certain area; besides, the reader-writer is simple in process and low in cost.
Description
Technical field
The present invention relates to a kind of rfid interrogator, particularly a kind of RFID integral type read write line based on gap area.
Background technology
Because traditional rfid interrogator existence read-write region is excessive, be not suitable for the scene based on gap area, in some scenarios, supvr only wants to read the label in certain region, but when some label rests in outside certain region, traditional read write line also can go reading tag.Such as: in container cargo distribution management process, some container can be parked in outdoors or in door, traditional rfid interrogator can read the label on these containers, but in fact supvr does not want to read these labels.Because these containers do not produce warehouse-in or outbound behavior, be only parking outdoors or in door, but their label is in read-write region, read write line will read their label, causes creating warehouse-in or outbound record.
Summary of the invention
For above-mentioned technical matters, the invention provides a kind of RFID integral type read write line based on gap area, comprising:
Shell, it is the untight casing in bottom, and described casing is not more than the width in described gap relative to the distance between biside plate;
Transmitter, it is placed in described casing;
Fixed mask plate, the lower surface of its biside plate relative to described casing is fixedly connected with;
Two turning axles, it is arranged on the lower surface of the other biside plate relatively of described casing;
Portable shielding plate, it is articulated on described two turning axles;
Fan-folded barricade, it to be coupled together by some fan-shaped barricades by folding turning axle to form, described fan-folded barricade is nested to be arranged on described turning axle, limit, described fan-folded barricade one end connects described fixed mask plate, other end limit connects described portable shielding plate, described portable shielding strip moves described turning axle, described turning axle drives described fan-folded barricade to open, and described fixed mask plate, portable shielding plate and fan-folded barricade form the space of all round closure.
Preferred version is: barricade is metal electric magnetic shield panel.
Preferred version is: barricade is copper coating electromagnetic shielding plate.
Preferred version is: barricade is aluminize electromagnetic shielding plate in surface.
Preferred version is: described turning axle is fixed on described side plate by rotating nut.
Preferred version is: some fan-shaped barricades are coupled together by folding turning axle by described fan-folded barricade.
Structure of the present invention improves the structure of traditional rfid interrogator, can control to read and write region, is applicable to the scene of application gap area, and supvr is obtained want the label in certain region of reading, this structural manufacturing process is simple in addition, and cost is low.

Fig. 1 is side view of the present invention;
Fig. 2 is front elevation of the present invention;
Fig. 3 is fan-folded barricade of the present invention and turning axle connection layout;
Fig. 4 is the door front view (FV) that the present invention reads and writes region;
Fig. 5 is the door outboard profile that the present invention reads and writes region;
Embodiment
Below in conjunction with accompanying drawing, the present invention is described in further detail, the present invention includes:
Shell 1, it is the untight casing in bottom, and described casing is not more than the width in described gap relative to the distance between biside plate;
Transmitter 15, it is placed in described casing;
Fixed mask plate 2, the lower surface 3 of its biside plate relative to described casing is fixedly connected with;
Two turning axles 4, it is arranged on the lower surface 6 of the other biside plate relatively of described casing by rotating nut;
Portable shielding plate 5, it is articulated on described two turning axles 4;
Fan-folded barricade 7, it is coupled together by some fan-shaped barricades by folding turning axle 8, on the nested two ends be arranged on described turning axle 4 of described fan-folded barricade, limit, described fan-folded barricade one end 9 connects described fixed mask plate 2, other end limit 10 connects described portable shielding plate 5, described portable shielding plate 5 drives described turning axle 4, described turning axle 4 drives described fan-folded barricade 7 to open, described fixed mask plate 2, portable shielding plate 5 and fan-folded barricade 7 form the space of all round closure, barricade can be metal electric magnetic shield panel, such as copper facing electromagnetic shielding plate or electromagnetic shielding plate of aluminizing.
Embodiment
Gap area is crack between a door and its frame, as shown in Figure 4, the high 2.2m of door, gate-width 1.5m, the width of gap area is 0.5m, length is 1.5m, the rfid interrogator of one is put on a beam on 11, when not installing the read write line of barricade structure, read-write region is that in Fig. 4, horizontal stripe region 12 adds vertical bar region 13, use structure of the present invention, rotate by regulating portable shielding plate 5 driven rotary axle 4, the fan-shaped barricade 4 of turning axle 4 Foldable is opened, then portable shielding plate 5 is fixed on a position by position limiting structure, read-write region is limited in vertical bar region 13, reduce the region not using barricade structure, vertical bar region 13 can regulate according to actual needs, the vertical bar region 13 of the present embodiment be limited in a container by scope.
Fig. 5 is the side bitmap of the present embodiment, the spacing of two blocks of fixed mask plates 2 is set to 0.5m, consistent with the width of gap area, when not installing the read write line of barricade structure, read-write region be 16 with region 17 sum, use structure of the present invention, read-write region is limited in region 16 by fixed mask plate 2, thus realizes under the scene based on door region, avoids producing unnecessary warehouse-in or outbound operation, cause irrational warehouse-in or outbound record, thus waste of manpower and material resources.
Although embodiment of the present invention are open as above, but it is not restricted to listed in instructions and embodiment utilization, it can be applied to various applicable the field of the invention completely, for those skilled in the art, can easily realize other amendment, therefore do not deviating under the universal that claim and equivalency range limit, the present invention is not limited to specific details and illustrates here and the legend described.
