Abstract
The utility model relates to the field of a reader-writer having the radio-frequency identification technology (RFID), in particular to a RFID reader-writer antenna output-field control device, which is provided with an antenna box; an antenna is arranged inside the antenna box through an elevation regulation device; two tracks are arranged on two side edges at the opening of the upper cover of the antenna box, and the tracks are movably matched with two sliding grooves arranged on two side edges of the box cover. The different spaces of the electronic tags can be correctly read and written down by regulating the upper and the lower positions of the reader-writer antenna; the electronic tags in different sizes can be correctly read and written down by regulating the width of the gap above a screen box of the reader-writer antenna; through the mutual cooperative regulation on the upper and the lower positions of the antenna and the width of the gap above the screen box, the packed burst-proof function of the electronic tags can be realized, and the read, the writing and the printing of the tags having different sizes and small spaces in the RFID printer can be correctly realized.
Description
Technical field
The utility model relates to (RFID) read write line field that has radio RF recognition technology, at length says it is control, the adjusting device of a kind of rfid interrogator antenna to space radiation energy and angle of radiation.
Background technology
As everyone knows, radio-frequency recognition system generally is made up of electronic label read/write and system, and wherein electronic tag is made up of label chip and label antenna, and reading and writing device system is made up of radio-frequency power control section, output and antenna.Electronic tag is generally attached on the object that is identified, when reading and writing device system is positioned at read-write regional of electronic tag, read write line takes out the identifying information in the electronic tag in contactless mode automatically, or information write in the electronic tag, thereby realize automatic read message or the function that automatically information is write, read write line comprises driver and antenna.When read write line to a plurality of target identification processes in, read write line will be read and write one by one to a plurality of labels, in order to prevent to collide, adopts the mode that reads of space division multiplexing, frequency multiplexing, time-division multiplex.Space division multiplexing antenna system complexity only limits to application of special occasions; Frequency multiplexing is the cost height of reader not only, and label need each have difference, brings more loaded down with trivial details; Polling method in the time-division multiplex needs all labels to want detailed sequence list, the inconvenience of increase and decrease label.Manyly in the time-division multiplex search method with binary system, in the RFID printer, collide for fear of the front and back label, adopt at present that spacing widens between the electronic tag, efficient is low, consumptive material increases thereby cause.
Summary of the invention
The purpose of this utility model be for solve the Card Reader required distance be not very big and the card spacing intensive, especially at the dense matrix Card Reader, antenna regulating device in the read write line that the label area is less and mutual spacing is less in the printer, a kind of rfid interrogator antenna output field control device is provided, realize that different size, closely spaced label are read and write printing exactly in the RFID printer, improve read-write efficiency, save consumptive material.
The technical scheme that the above-mentioned technical deficiency that solves the utility model adopts is: be provided with antenna box, through elevation and subsidence regulating device antenna be installed in the antenna box, be processed with guide rail on the dual-side of antenna box upper shed, the chute on guide rail and the lid dual-side is slidingly matched.
The utility model also can be realized by following measure: lid is side by side two or is one.Elevation and subsidence regulating device adopts the screw rod lifting, adjusts the screw rod spinning in the tapped through hole of base plate, and the upper end mortar head of adjusting screw rod is inserted in the mortar bowl of antenna supporting plate downside.
The beneficial effects of the utility model are, provide in a kind of rfid interrogator the antenna input to the energy of space radiation and may command, the adjusting device of angle of radiation, purpose is by regulating the upper-lower position in antenna rfid interrogator sky, the spacing difference of realization electronic tag all can be read and write exactly, by regulating the gap width of reading and writing device antenna shielding box top, realize the read-write exactly of different size electronic tag; The adjusting that width by slit, antenna upper-lower position and shielding box top cooperatively interacts realizes the intensive anti-collision function of electronic tag, realizes that different size, closely spaced label are read and write printing exactly in the RFID printer.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
