Abstract

An omnidirecitonal high frequency label reader-writer is disclosed, a plurality of antennae are disposed in an annular container at particular interval to form an annular antenna region, in order to form a consecutive reader-writer, each of antennae is connected with a reader-writer that controls an antenna, all the reader-writers are interconnected via a serial port and a controller, the controller controls read/write sequence of each group of reader-writers until reading an electronic label. The utility model has the advantages that the annular large antenna composed of a plurality of antennae forms a consecutive read-write region, when the electronic label enters into a radiation range of the electromagnetic wave, the electronic label is enabled to obtain an energy activation microchip circuit from an electromagnetic field, the chip is converted into the electromagnetic wave and then sent to the electromagnetic field region formed by expanding reader via the reader-writer, thus remarkably increasing read/write range of the reader-writer so as to enhance reading rate for the electronic label.

Description

Omnidirectional high-frequency label read-write machine

Technical field

The utility model relates to a kind of intelligent label read write line, particularly a kind of omnidirectional high-frequency label read-write machine that has enlarged effective recognition scope.

Background technology

Electronic tag generally all is fixed on the object, label need be moved to during read-write in the electromagnetic field scope of read write line formation, and label could effectively be distinguished.Therefore, before recognition, adjust the position of label or read write line, wasted the working time, reduced the actual read-write rate of label.

The utility model content

Technical matters of the present utility model is that a kind of omnidirectional high-frequency label read-write machine that improves the tag readable degree rate will be provided.

In order to solve above technical matters, the utility model provides a kind of omnidirectional high-frequency label read-write machine, several antenna spacing certain distances are positioned over the antenna area of forming annular in the toroidal container, form a continuous read-write zone, the electromagnetic field radiation scope of antenna is overlapping at boundary, forms territory, a magnetic field.Each antenna is connected with a read write line, antenna of a read write line control, and all read write lines are connected with a controller by serial ports.

Described read write line is that two above read write lines are one group at least, preferred plan is that the 2-4 read write line is continuous read-write zone of one group of formation, control the read-write order of every group of read write line by controller, until distinguishing electronic tag, on having guaranteed that label can any position in a wider context, can both be distinguished apace.

In column type label antenna part, column type two rings up and down adopts epoxide resin material, explosion-proof; The ABS material is adopted in the column type side, anti-shielding action.

Superior effect of the present utility model is: the big antenna of annular that the utility model is made up of a plurality of antennas, form a continuous read-write zone, in electronic tag enters this electromagenetic wave radiation scope, make electronic tag from electromagnetic field, obtain energy activated microchip circuit, chip transforms electromagnetic wave, re-send to read write line and enlarged the formed electromagnetic field of reader zone, increased the read-write scope of read write line greatly, thereby improved electronic tag recognition rate.

The number in the figure explanation

1-antenna; 2-read write line;

3-toroidal container.

Embodiment

See also shown in the accompanying drawing, the invention will be further described.

As shown in Figure 1, the utility model provides a kind of omnidirectional high-frequency label read-write machine, several antennas 1 keep at a certain distance away and are positioned over the antenna area of forming annular in the toroidal container 3, form a continuous read-write zone, the electromagnetic field radiation scope of antenna is overlapping at boundary, forms territory, a magnetic field.Each antenna 1 is connected with a read write line 2, antenna 1 of read write line 2 controls, and all read write lines 2 are connected with a controller by serial ports.

It is one group that described read write line 2 is three, controls the read-write order of every group of read write line 2 by controller, until distinguishing electronic tag, guaranteed that label can any position in a wider context on, can both be distinguished apace.

The utility model provides 9 antennas 1, corresponding 9 read write lines 2, and 1-9 numbering in order, the 1-9 numbering also is the serial ports numbering of these 9 read write lines 2; 9 read write lines 2 are divided into three groups, 1,4,7 is one group, 2,5,8 is one group, 3,6,9 is one group, opens one group of read write line 2 by controller control at every turn and carries out read operation, if do not read, then open another group, all open end up to three groups, if all do not read, then thinking does not have label on every side or label has damaged or label is in bigger rocking and does not put surely.

Generally speaking, when bringing into operation, the controller acquiescence is the UID that 1,4,7 these group read write lines 2 are read label; When the UID of label was not read in the Status Flag demonstration of read write line 2, controller control was automatically opened

second group

2,5,8 read write lines 2, allows this group read write line 2 read the UID of label; When the UID of label is not read in the Status Flag demonstration of read write line 2, controller control is automatically opened the 3rd group of 3,6,9 read write line 2, allow this group read write line read the UID of label, a read write line 2 that has in this course in one group is read label, 2 pairs of labels of this read write line carry out data read then, individual Status Flag is also arranged when fetching data, represent whether read data according to this Status Flag, 2 pairs of labels of this read write line carry out write operation if read then.

Before the reading of data, can allow the UID of read write line 2 reading tag earlier, because the time of reading UID is shorter than the time of read data, 9 read write lines 2 all are provided with Status Flag and represent whether get UID, after the Status Flag of read write line 2 is represented to read UID, just use 2 pairs of label reading of data of this read write line.

Claims

1, a kind of omnidirectional high-frequency label read-write machine is characterized in that:

Several antenna spacing certain distances are positioned over the continuous antenna area of forming annular in the toroidal container, and each antenna is connected with a read write line, and all read write lines are connected with a controller by serial ports.

2, by the described a kind of omnidirectional high-frequency label read-write machine of claim 1, it is characterized in that:

Described read write line is that two above read write lines are one group at least, is controlled the read-write order of every group of read write line by controller.
