Description

FIELD OF THE INVENTION

The invention relates to electrical engineering, and more specifically to devices for reading RFID tags.

BACKGROUND

RFID readers are well known. The most widely known part of them relates to readers of a stationary type, designed to prevent the removal of objects, with radio-frequency tags attached to them outside the trading room, which predetermines their technical (readers) characteristics, in particular, a relatively long response distance and insufficiently clear contours of the stable zone detection, which leads to false positives when the label is carried next to the detector on either side. In addition, well-known detectors of this type react to any goods equipped with a certain radio frequency tag, and can only be used to determine the very fact of the presence of goods in the stable detection zone, but are not suitable for determining the number of tags or reading tags of various types (i.e., determining the number and type of goods). Even if the reader has the necessary hardware and software capabilities to determine the number and type of radio frequency tags in the detection zone, this does not allow them to be reliably used (readers) to account for marked goods, due to the low reliability associated with shielding the radio signal from foreign objects, especially metal ones, and the product itself.

Thus, to date, no means have been created for reliable simultaneous determination of the quantity and type of commodity units, especially small metal products marked with radio frequency tags with different identifiers.

Meanwhile, the creation of such a tool could significantly simplify and speed up accounting and inventory operations if it is necessary to move a large number of units of labeled goods, for example, when transferring labeled jewelry from a place of storage to retail chains.

SUMMARY OF THE INVENTION

The terms and expressions used in this text are given the following meaning.

A near-field radio-frequency tag is a radio-electronic device configured to remotely transmit a pre-recorded identifier in the form of radio waves.

The remaining terms and expressions are used in the usual sense for their context and technical field, which is well known to specialists and requires no explanation.

The objective of the present invention is to expand the arsenal of means for simultaneously reading near-field RF tags from a group of at least two tags, which in their technical qualities would be suitable for quickly accounting for a large number of valuable items marked with these tags.

The technical result consists in leveling the effect of screening with marked products of signals of near-field radio-frequency tags while reading identifiers from a group of at least two tags, as well as in preventing false triggering if the tags accidentally fall into the area adjacent to the detection zone.

This result is achieved due to the fact that the device for simultaneous reading of identifiers from a group of near-field RF tags contains a metal case with an internal cavity for accommodating products marked with the said tags, and an antenna located inside it (case) for reading them, in which the said case equipped with a hole for connecting the aforementioned antenna with a cable, a boot hole and a removable metal cover, made with the possibility of a snug fit along it (holes) contour.

As will be clear to a person skilled in the art, the problem is solved due to the totality of the characteristics of the luminaire, while the aforementioned technical result is achieved by making the housing without holes through which extraneous electromagnetic signals can penetrate, and also due to the device’s design provides conditions for effective manual or mechanized shaking, mixing and tedding of products with marks placed inside the cavity.

In one particular embodiment, the lid and housing mentioned above are provided with means for releasably securing to each other.

In yet another particular embodiment, the device is further provided with an electromechanical agitator mounted inside said cavity.

In another particular embodiment, said housing is pivotally mounted on a bed with a possibility of rotation about a horizontal or inclined axis.

In one particular embodiment, said horizontal or inclined axis substantially coincides or forms an angle of less than 35 ° (inclusive) with its own longitudinal axis of said housing.

In another particular embodiment, said horizontal or inclined axis forms an angle of more than 45 ° (inclusive), preferably 90 ° with its own longitudinal axis of said body, thereby allowing it (the body) to tip over for unloading and loading.

In another particular embodiment, said lid is mounted on hinges fixedly mounted on said housing.

In one particular embodiment, said lid is mounted on hinges fixedly mounted on said bed.

In yet another particular embodiment, said body is mounted in a gimbal suspension for rotation about its own axis for tedding the products placed inside the cavity and rotatable in a vertical plane for unloading and loading them (products).

In another particular embodiment, the device is additionally equipped with electric drives and automation means to ensure the loading of said products, their tedding and unloading according to a predetermined program.

In one particular embodiment, the housing is pivotally mounted on a substantially horizontal or inclined shaft, with the possibility of tipping over during rotation.

In yet another particular embodiment, the walls are internally provided with a soft coating.

In another particular embodiment, said coating is provided with shock absorbing radial protrusions.

This technical result is also achieved due to the fact that in the method for simultaneously reading identifiers from a group of RF tags by means of the above-described device and any of its particular embodiments, the products marked with RF tags are loaded inside the aforementioned cavity, the aforementioned loading opening is closed with the aforementioned lid, and the products are shaken or agitated. by simultaneously or alternately reading identifiers from RF tags

In one particular embodiment, tedding or shaking is stopped if the number of unique tags read does not change over a predetermined time period.
