Description

Reading apparatus for reading out information from a transponder and method for controlling a reader

The present invention relates to a reader for reading information from a transponder according to claim 1 and a method for controlling a reading device for reading information from a transponder according to claim 12th

Transponders are passive devices, to be processed to identify and / or be used for transporting objects and goods. Depending on a transponder is attached either to the object itself or on a container containing the object. In the transponder information is stored or contained, which can be read by appropriate transponder readers. Each container or each object is typically a transponder permanently assigned. The transponder readers are available as read-only or read-write devices. The transponders are also available as read-only or read-write transponder. In the read-only version of the transponders usually by the manufacturer with a guaranteed unique identification information are described as a number. During use, the transponder is then read out by the read-only devices at the respective processing stations or transport.

In the read-write version of the transponders can read-write devices to the transport or processing stations are not only read, but also with relevant new information is described, for example, information regarding the processing status, etc. The transponder readers are connected to a central control computer to communicate the updated transport or processing steps with respect to each transponder or of the respectively assigned a transponder object usually by means of a radgebundenen network or a wireless network. The information may be used to control the processing and transport of the transponder carrying objects, one or just for display and monitoring.

The applications of the transponder and the corresponding transponder readers are very numerous. For example, the transponder for identification of objects such as pallets, trays, magazines, boxes, tubs or other can be transported, used to be processed or objects to be sorted.

The technical prerequisite for reading a transponder basically consists in that the transponder must be located relative to the reading device in a certain position. To be able to detect a transponders in any orientation, systems have been used so far from multiple antennas constituting one or a plurality of influencing static fields. In order for a transponder can be detected by such an antenna system in any orientation, it needs to move through the field, the conditions change in the field with respect to the orientation of the transponder to the antenna.

A disadvantage of systems with static antenna arrays is the dependence of the read rate of the speed of the moving objects. If the movement is uneven, for example, carried out by a person, the varying speed has a negative impact on the success of the reading.

Object of the present invention is thus to provide a device which allows to read transponders in any orientation and / or to describe, without the transponder must move through the antenna field for this purpose.

The object is achieved by a reader for reading information from a transponder according to claim. 1

In a preferred embodiment, include at least two intersection points of two different pairs along the circumference of the container at an angle of 90 °.

Advantageously, each antenna is associated with a control unit which activates the antenna.

Further advantageously serves means connected to all of the control units control unit for selective control of individual antennas using the corresponding control units.

The present invention will be explained in more detail below with reference to figures. Here, Figure 1 shows a first view of a reading apparatus according to the present invention,

2 shows a second view of a reading apparatus according to the present invention and

3 shows a third view of a reading apparatus according to the present invention.

1 shows a first diagram of a reading device 10 according to the present invention. The reading device 10 here comprises a container 1 which has an interior space 2 for receiving objects. The container 1 can have any shape and size, in a preferred embodiment, the container 1 is cylindrical. The container 1 may in its interior 2 receive one or more objects which are provided with a transponder or which are located in a further container which is provided with a transponder. The container 1 further comprises a display device 3 such as a display, for displaying data and information for a user. Via an input device 4 such as a keyboard or a touch Päd, the user can enter data or information or access or select menu functions. Means connected to the display device 3 and the input device 4, control unit 5 monitors and controls the read and write operation of the reader 10. The control unit 5 may be connected via a network or by radio to a control computer (not shown) from which they data receives control of the reader 10 and to which it transmits information. can to such a central control computer more control units 5, which are associated with different reading devices 10 may be connected.

The container 1 further comprises further components, which are necessary for the functionality, for example a power supply or battery, which are not shown in the figures, however for clarity.

Figure 2 shows a second representation of the reading device 10 according to the present invention. For emitting a read-out signal to a transponder and for receiving a light emitted from the transponder in response to the readout signal response signal multiple antennas 7 are arranged around the container. 1 The antennas 7 in this case comprise the container 1. Here, the antenna is disposed around the vessel 1 7 and the container 1 can either completely largely enclose or at least. The shape of the antenna 7 may either be adapted to the shape of the container 1 or any other desired shape.

For a reading device 10 according to the present invention, at least two antennas 7 are used, in a preferred embodiment a total of four antennas 7 are used. The antennas and the container 1 may thereby be of any shape, in a preferred embodiment, the container 1 is cylindrical and the antennas 7 annularly. Each antenna is entirely a one plane.

The antennas 7 are here in each case to two antennas 7 existing pairs 6a, 6b. The antenna 7 of a pair 6a, 6b are arranged so that they overlap in two crossing times 8. Advantageously, the angle α, which is enclosed at the crossing points 8 of two antennas 7 of a pair 6a, 6b, 90 °, according to also have the planes in which the two antennas 7 of a pair 6a, are 6b, an angle of 90 to each other. Furthermore, the pairs 6a, 6b, the container 1 comprising arranged so that the points of intersection 8 of two different pairs 6a, 6b are spaced apart. Advantageously, have at least two points of intersection of two pairs 6a, 6b spaced apart a distance corresponding to a quarter of the circumference of the container. 1 In the case of a cylindrical container 1, the crossing points have 8 thus circumferentially spaced of 90 °.

This arrangement of antennas 7, it is possible to detect by selective control of individual antennas 7 a transponder located in the interior 2 of the container 1 and to read out. The location of the transponder is in this case irrelevant, since the transponder 7 can be detected in any position due to the arrangement of the antennas.

Figure 3 shows a third representation of the reading device 10 according to the present invention. Here, the antennas are disposed 7 comprising advantageously the container. 1 Each antenna is associated with a control unit 9, which activates the respective antenna 7, that is, which starts the transmission and / or reception operation of the antenna. 7 By means of the control units 9 can be selectively driven in each case an antenna. 7 Furthermore, the antenna can be physically separated to the control unit 9 7, whereby a resonance of an antenna while the transmitting and receiving operation of another antenna is avoided. 7 The control units 9 are connected to the control unit 5 and can be selectively driven by the control unit. The process of reading or writing of a transponder according to the invention by means of the reader 10 will be described below. After the objects that are marked with a transponder placed in the inner space 2 of the container 1, the read operation is started. This can either be done manually by entering via the input device 4, via a command from the control computer, which is transmitted to the control unit 5, or by automatic sensors. For the read operation of the control unit 9, the antenna 7 are individually connected to the control unit 5 successively. This is only an antenna array active and thus can not be affected by the antenna fields of the other antenna. 7 Moreover, the respective control unit 9 of the non-active antenna 7 separates the non-active antenna 7 to the antenna physically ring, whereby a coupling of the antennas to one another is excluded. Thus, the non-active antenna 7 can not resonate with the respective active antenna 7 and evade this energy. In which the nodes 8 of pairs 6a, 6b have a distance of a quarter of the circumference of the container, can be activated 6b instead of a single actuation of the antennas 7 and each having a pair 6a. Through the control of the two antennas 7 of a pair 6a, 6b and by the arrangement of antennas 7 of a pair 6a, 6b at an angle of 90 ° at the nodes 8, results in a rotating field in which the antennas do not affect each other. When controlling a pair 6a, 6b, the performance of the reading device is distributed to both antennas. After the completion of the read operation, the user can be informed by a visual or audible notification.

An example of application of the reading device according to the invention is given, for example, in a dry cleaning. The individual items of laundry can be equipped with a transponder for recognition here. For the identification of the laundry articles during or after cleaning the items of laundry can be loose or be placed in a laundry bag in the container. 1 By the reading device 10, the pieces of laundry can then be identified and information is read out on the state of the pieces of laundry or written. The advantage of using is that the clothes are at rest and thus always reach a defined state.
