Abstract
The invention relates to an omni-bearing high frequency tag reader-writer, a plurality of antennas from space to space are arranged in a toroidal vessel to form a toroidal antennas region, forming a continuous reading-writing region, each antenna is connected to and is controlled by a reader-writer, all readers-writers are connected to a controller through a serial port, the reading-writing orders of each group of readers-writers are controlled by the controller, reading up to an electronic tag. The invention has the advantages of that a big toroidal antenna which consists of a plurality of antennas forms a continuous reading-writing region, the electronic tag obtain energy from an electromagnetic field to activate a microchip circuit when the electronic tag enters into the radiation range of the electromagnetic wave, the chip transforms and sends the electromagnetic wave to the reader-writer, thereby widening the electromagnetic field region formed by the readers, greatly improving reading-writing range of the reader-writer and the readable degree of the electronic tag.
Description
Technical field
The present invention 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.
Summary of the invention
Technical matters of the present invention 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 invention 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 to be one group more than two at least, preferred plan is that 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.
The control method of omnidirectional high-frequency label read-write machine, its job step is as follows:
1) first group of read write line read the UID of label;
2) whether affirmation reads the UID of label; , do not change the 7th) step;
3) be to read the data block of label with corresponding read according to Status Flag;
4) whether affirmation reads the data block of label; , do not change the 6th) step;
5) be the data block of writing labels;
6) finish;
7) second group of read write line read the UID of label;
8) whether affirmation reads the UID of label; Be to change the 3rd) step;
9) not, the 3rd group of read write line read the UID of label;
10) whether affirmation reads the UID of label; Be to change the 3rd) step;
11) not, change the 6th) step.
Superior effect of the present invention is: the big antenna of annular that the present invention 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, simultaneously, because the time of reading tag UID is shorter than the time of read data, before the reading of data, can allow read write line get the UID of label earlier, thereby improve electronic tag recognition rate.

Embodiment
See also shown in the accompanying drawing, the invention will be further described.
As shown in Figure 1, the invention 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.
Described read write line 2 is three and is one group and forms a continuous read-write zone, 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.
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.
As shown in Figure 2, the control method of omnidirectional high-frequency label read-write machine, its job step is as follows:
1) first group of read write line read the UID of label;
2) whether affirmation reads the UID of label; , do not change the 7th) step;
3) be to read the data block of label with corresponding read according to Status Flag;
4) whether affirmation reads the data block of label; , do not change the 6th) step;
5) be the data block of writing labels;
6) finish;
7) second group of read write line read the UID of label;
8) whether affirmation reads the UID of label; Be to change the 3rd) step;
9) not, the 3rd group of read write line read the UID of label;
10) whether affirmation reads the UID of label; Be to change the 3rd) step;
11) not, change the 6th) step.
The invention provides 9 antennas 1, corresponding 9 read write lines 2,1-9 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.
