Description

An electronic label, methods for monitoring good and method for data communication

Background of the Invention

The present invention relates to an electronic tag and to a method for monitoring well by means of the same. Further, the invention relates to a procedural for data communication.

In almost all applications in the areas of warehousing, logistics and transport of materials and articles, it is necessary to identify individual storage or transport units so that people can clearly identify the contents from the outside without having to open the container. The classic solution of this problem is now in the fitting of non-reusable paper or film labels that are labeled or printed prior to attachment to the container.

The labeling of containers is problematic. There are tons of resources but destroyed label paper, because it is not possible to use them again. Moreover, once applied, information can be extremely laborious and costly to be changed (manually or by gluing) or corrected because a change of such labels is only possible manually by overwriting or covering on a label.

is exacerbated in particular the last mentioned disadvantage of the conventional container labels in those cases in which the product, batch or series-related marked has a usability status, the rungs- themselves during storage or transport time changes. In these cases, the visibility of the current status of the goods for a unique identifier from the outside is essential. In in various industries such as the pharmaceutical, cosmetic, food, biotechnology, medical device industry, the status identification of raw materials, semi-finished goods and finished goods is even a legal obligation for manufacturers and transporters.

To solve this problem, now corresponding machine-readable identification codes are applied to the labels. As identification code bar codes are used, with the help of the current status of the goods unit of a batch or series appears. However, this requires the support needed by a computerized system. This means that it is not possible here to make the current status can be seen even without additional support systems for people.

Furthermore, so-called smart labels (smart labels) are known. Such intelligent labels can be equipped for example with contactlessly scannable transponder dersystemen (so-called RFID tags), via which information is available. The RFID transponder is generally made up of an antenna, an analog circuit for receiving and transmitting (transponder), a digital circuit and a permanent memory.

It is generally between active and passive RFID T distinguished ranspondem. Passive RFID tags have no power source and must obtain their supply voltage by induction from the radio signals from the base stations. Active RFID transponders have gieversorgung own energy and achieve a significantly higher range. They have more features, but also cause significantly higher costs per unit.

Such a smart label is described for example in DE 0 699 08 381 T2. The label has layers which are stacked with each other. The

Layers comprise an antenna element, a processor, a memory, like a so-indicator assembly. The label information can be viewed and modified.

DE 600 00 478 T2 describes briquettes another embodiment of an intelligent la-. The label has two electrical attachment pads of a first electric material, a layer of a dielectric material, an antenna of a second-electric material and an expandable material. The expandable material forms a cavity surrounding the attachment pads and receives a chip in the form of an integrated circuit.

Furthermore, DE 102 04 884 A1 a smart label is described which can be attached to a metal object. The label comprises a resonant circuit having a resonant frequency in the RFID standard range of 13.56 MHz, and a film with increased permeability. The thickness of the film and the relative permeability are matched to the metallic article, the label is sufficiently magnetically shielded.

DE 103 36 321 A1 further describes an intelligent tag having an electronic circuit, a memory and an apparatus for data transmission and a sensitive area. If the sensitive area registered targeted impingement, it generates a pulse for the connected with the device for data transfer control agent. The control means then releases a data transfer from situated on the label data to a display device on which a user can view the data.

Underlying task

The invention has the object of providing an effective, reusable

provide label that can be independently operated and changed remotely. The label should still be able to information in a -A-

display form readable by a human as well as to enable detection of position rungs- and transport damages.

It is another object of the invention is to provide a method for monitoring Ll- capable of good.

Another object of the invention is to provide a method by which a data communication between a data communication center having a plurality of labels is effective and allows few errors.

Erfindungsqemäße solution

According to the invention, the label

- at least one carrier component, - at least one antenna,

- wherein the display comprises arranged on a support at least one electronic ink, display,

- at least one transponder, and

- at least one sensor means.

so that the label has components that enable a human-readable display, a permanent storage of data and the detection and processing of data from the environment.

Overall, the present invention provides a reusable electronic label ready to fulfill the following requirements:

- it is in accordance with current standard labels in different dimensions to produce,

- it is flat and flexible and can be easily attached to various containers, cartons and containers - it's several times and optionally describable with human readable alphanumeric characters and symbols,

- by appropriate signals from the outside, certain information on the display (for example, status) to be changed, and - all the identification information can also be stored in electronic form in a memory.

Such a label can be manufactured economically in quantities. By reusability, attributable removal and storage operations and corresponds falling relabeling when changing the displayed information costs can be saved. The savings achieved compensate for the additional costs of the equipment needed to write or modify information on the label.

According to the invention a method for monitoring material is further provided, which comprises an oversight of the material according to the invention with a label, and recording, detecting, modifying and / or maintaining information on the electronic label.

In particular, information is recorded in a form on the label that are readable by a human without tools. The recorded information also remain without electricity supply to the label obtained, that they are permanently stored and can be permanently displayed on the label. The permanent, human-readable display information in particular is a property of the used electronic ink in which a microcapsule is used to represent a pixel. In the capsule charged particles in an oily liquid or a gel are positive or negative stored. The particles are, for example, white and black. Between an inner and an outer electrode each in the form of a foil film, the microcapsules are arranged, whereby the control of individual pixels across the electrodes is possible. An electrically positive field is applied across the inner electrode, the white particles move towards the surface of the microcapsule sel. At the same time over the outer electrode, which is transparent, applying a negative field which moves the black particles to the inside and thus makes invisible. For a white pixel is generated. The generation of a black pixel is analogous. The orientation of the pixels is stable, so that the display of the information does not go out even without external power supply.

The inventive method for data communication between a data communication center with a plurality of labels, comprises the steps, carried out by at least one of the labels:

- receiving a data packet transmitted from the data derived from the central communication unit and / or a label itself and / or by a different label;

- processing the data packet within the label; - check of the data packet based on whether the label is the intended recipient for the data packet;

- If the check shows that the one label is not the desired recipient for the data packet, then sending the data packet to the data communication center and / or to a different label, and / or to the label itself.

The label usually appear in a variety in a non-homogeneous spatial distribution of individual and are in communication with the data communication center. According to the data communication between the data communication center is chain with the plurality of labels via the la- accomplished itself so that each label needs to communicate with the data communication center not directly. Thus it is sufficient if at least one label in data communication is related to the data communication center, as the labels each perform a data exchange. This ensures that each tag receives the specific data for him, even if the label is not related to the data communication center di- rectly connected. Thus, the data communication between the data communication center and the individual labels is easy and few errors.

Advantageous developments of the invention

In preferred embodiments, the at least one sensor means is a sensor means for detecting a temperature, in particular the ambient temperature. By detecting the temperature if a label provided with the container is stored in an allowable temperature range can be determined. This plays especially in frozen foods, for drugs and for temperature-sensitive starting materials requiring storage in a certain temperature range, an important part. For example, the purchaser of cooling goods can appreciate from the inventive label stored in the label detected temperature values, and detect whether the goods have been transported in a predetermined temperature range and stored, or whether the product was subjected to in transit or storage of a temperature which is not in the predetermined range.

Alternatively or in addition, the sensor is a sensor for detecting pressure, in particular ambient pressure. Based on the label according to the invention can be determined whether a container provided with the label has been exposed to pressure fluctuations and is. This plays especially in containers in which chemicals are stored, an important role, because chemicals can assume different structures under different pressures and suspension under pressure - to decomposition back - are changeable.

For the purposes of the present invention, a transmitter / receiver unit and is understood to be a transponder. Advantageously, the transponder comprises an integrated circuit which includes other components. The integrated circuit further advantageously comprises a processor and a memory so that data can be processed and stored. Preferably, the transponder is an IC chip. In an advantageous embodiment, the sensor means is further integrated in the integrated circuit.

Preferably, the processor is adapted to control the at least one sensor means such that the ambient temperature and / or the ambient pressure is detected at predetermined time intervals, and the memory adapted to store the detected ambient temperature and / or ambient pressure. This allows a long-term recording of the bearing temperature and / or the bearing pressure and makes it possible to verify that the goods are stored in the vorbestimm- th temperature and / or pressure range or has been. In addition, when exceeding the predetermined temperature and / or pressure range, the time period can be detected, in which the temperature and / or pressure surge took place.

In a preferred embodiment, the processor is adapted to generate a signal which changes the display on the display. For example, the processor may include one or more programs are stored in the memory, to initiate or execute. So that he can determine which information is displayed by the display and generate a warning that the predetermined temperature-ratur- and / or pressure range has been exceeded. The warning is for example a flashing label display. Alternatively, the color of the label can display, that is, the carrier or the electronic ink change. The availability status may change, for example, when a specific batch is blocked due to lack of durability or danger.

In a further preferred embodiment, the electronic ink, electronic ink that changes color in dependence on the detected temperature from the sensor means. This storage damage may for example be displayed immediately visible to humans in food purchases. One example of an electronic ink which is able to change the color, based on particles that are stacked in a polymer gel matrix. marl to the conductive poly a voltage is applied, the positively charges the polymer and more or less determines how much solvent absorbs the gel. Depending on the absorbed amount of solvent, the gel swells and change the distances between the particles. are tikeln depending on the distance between the Par certain wavelengths of incident light eliminated, thus creating a color impression. When the ink is displayed, for example, in blue color on the display, it indicates that it is in a temperature range from 0 to 10 0 C. When the ink appears in red on the display, it indicates that it is located in a temperature range of 11 to 25 0C. When the ink is visible in red on the display, the buyers of frozen products that must be stored at a temperature from 0 to 10 0 C can tell at a glance, even in the acquisition of goods that the permissible temperature range has been exceeded, and the product is therefore deficient. The support on which the electronic ink is arranged, is in particular a polyvinyl lymermaterial such as plastic.

In an advantageous embodiment, the antenna comprises a KW-FM antenna. Alternatively, the antenna consists of a dipole with an integrated circuit in the antenna coil and an applied on the substrate antenna.

The carrier component advantageously comprises plastics. Plastics are inexpensive materials. For applying the label to a surface has the carrier component is advantageously an adhesive layer. The carrier material advantageously comprises polyethylene. Polyethylene is an inexpensive material, and can have by the addition of adhesion-promoting compounds during its manufacture in addition an adhesion-promoting properties. Alternatively, the carrier component comprises polyimide. Polyimide has good thermal properties. The carrier component, the antenna, the display, the transponder, the sensor means and / or other components of the label according to the invention are advantageously connected to each other. For example, the components of the label by adhesive bonding, soldering or potted can be connected together.

In a preferred embodiment, the label is carried out in layer form. That is, it comprises at least in each case one carrier component layer, the antenna layer, the display layer, and a controller layer containing the transponder, the sensor means, the processor and the memory. By schichtför--shaped embodiment of the label, the label is flat and is not from. The layers are preferably arranged in stacked manner. In particular, the label has a thickness of 1, 5 to 5.0 mm.

The label has at least one sensor means which has to be said first effective reasonable so that information or data recorded on the label and / or can be changed. The response of the sensor means is done by a specific action on the label. For example, the label can be acted upon by a radio signal. By applying a signal is generated, so that the processor executes instructions. For example, the processor may cause the sensor means to detect the ambient temperature, and causing the memory to store the detected ambient temperature. So can be ambient temperatures, the label detek- advantage on the one hand, and the detected ambient temperatures are interrogated by a purchaser of a product bearing the label during shipping.

Further, the processor may be in communication with a control means to which it outputs a signal for an effective impingement, wherein the signal for the control means is the character to check the authorization of access to the label in the stored data. Preferably, the label of the invention comprises the control means. For example, an electrical connection exists between the label and an authorization device of the customer. The transponder and the antenna respectively receive a signal from the authorization device. On the signal received by the antenna, the processor power is supplied while using the signal received by the transponders, processor, a data code is transmitted. The processor processes the data code output by the transponder and generates a data code signal is output to the control means. The control means checks based on the data code signal whether the identity allows access to stored in the memory of the label data, and generates a signal which enables the data or indicating an unauthorized access.

Furthermore, the present invention relates to a method for monitoring well. Good means container all etikettierbaren objects, particularly cargo, loading, packaging, containers, pallets, cars, animals and the like. The method includes providing a material with a label that has at least one carrier component, at least one antenna, at least one display, including arranged on a support electronic ink at least one transponder and at least one sensor means, and recording, Erfas- sen, changing, and / or holding information on the electronic label. The provision of good with such label allows wireless Ü monitoring of the material. The label provides an electronic marking is, and in the memory of the label all the information or data is written. For example, this information may be all needed for safe storage of the material data. In particular, during the storage of chemicals or pharmaceuticals, these data are, for example, the allowable current availability status, the storage temperature, Hazard symbols, R / S-sets and other safety information. Further, the display of the electronic label can be changed when, for example, by means of the Sensormit- means of suitable, for example, for detecting the ambient temperature and / or the ambient pressure of the label, an ambient temperature and / or an ambient pressure is detected, and / or the outside a predetermined allowable temperature and / or pressure range is or are.

In a preferred embodiment of the process the information is at least partially encrypted written in the memory of the label and / or encoded in memory. This prevents counterfeiting is increased. So that neither the sender and recipient data can be manipulated during transport, yet can be changed by the temperature sensor de- tektierte data, for example, without proper authorization exists and is the person who changes the data identified and registered. So goods can for example be easily assigned to the receiver and sender at customs and manipulation attempts are displayed.

In a preferred embodiment of the present invention, the information in the memory of the label can be repeatedly erased and new information is repeatedly written. Characterized the label is reusable. In addition, it can also be supplemented by information or other constituents. For example, an intermediate collector which further processes a resulting intermediate, hinzufü- its manufacturing data on the label gen. Authorize Preferably, prior to the change of information on the label requested in order to increase the security of the label.

In a preferred embodiment of the method according to the invention the label is chen addressed at predetermined intervals from an external device. The external device is in particular a read / write device such as a transmitter which transmits a signal to the processor of the label. Characterized the label is energized and allows accesses such as reading, writing and / or detecting a temperature or a pressure to the label. Energy is transferred through a magnetic field, which builds up between the external device and the label. A change in voltage in the read / write device leads to a change in field strength, which causes a change in voltage in the label. The thickness and length of the signal of the external device is adapted to the need, the label energy requirements. The energy requirement is determined by the amount of data to be transmitted and the distance between the external device and the label, the power consumption of individual label components as well as the type of access. For example, require write access more energy than reads. which is sent from the external device to the label the signal, in particular, has a frequency in the range of 1 to 10 MHz.

The response of the label from an external device at predetermined time intervals allows taking place at regular intervals of energy. The processor is programmed advantageously such that it causes the sensor means when power is supplied from an external device to measure the temperature and / or pressure. The sensor means outputs the detected temperature and / or the pressure detected to the processor. The processor causes a memory, the detected temperature and / or the pressure detected to be stored. The memory may be arranged in the inventive label. Alternatively or additionally, the memory is an external memory device. Due to the detected temperature of the processor can also causes the thermochromatic ink to change color.

In a preferred embodiment of the invention the information which is written in the label is read at predetermined time stalls. This is particularly useful if stocks are to be reviewed. It is possible to perform in this way an electronic warehouse inventory. For example, are being tested on the last day of the month the stock. Further, the temperature data can be determined by detecting, for example, whether a cooling device limit on its Kühlkapazitäts- has reached, for example if all of the labels, which are located in the cooling device, output temperature data, which are close to the allowable limit of the predetermined temperature range. Preferably, the method of the present invention has for data communication between a data communication center and a plurality of labels the step of: checking whether the label of the desired recipient for the data packet is based on a generated by the data communication unit and attached to the data packet identification.

Thus the addressing to the desired label is generated by the data communication center, said data packet including the addressing.

Further, the method includes the step of: checking whether the received data packet is complete and / or error-free and / or overlaid with other data packet.

Characterized that the data package that is transmitted to one another label from the, is checked for accuracy is achieved. Thus, the data transfer between the labels is few errors, whereby the error rate in the data communication between the data communication center and the desired label is low.

Moreover, it is preferred that the method comprises the steps of: checking on the basis of the data packet, whether a response data packet is required in response to the data packet; Generating the response data packet in response to said data packet; Transmitting the response data packet to the data communication center and / or to another tag and / or to which a label itself.

This provides the corresponding label with the data communication center in reverse communication, so that a dialogue between the corresponding label, and the data communication center is made possible. It is preferred that the method comprises the steps of: checking whether the data packet has already been received as an identical data packet from the one label; If the check shows that the data packet has already been received as an identical data packet from the one label, then discarding the data packet.

A double and thus redundant processing of the data packets is not necessary because it does not constitute information gain. Characterized that a received already as an identical data packet data packet is discarded, is suppressed, but that an already received data packet is processed at a later time again. Thus, the advent of data processing in each individual label is minimal.

Further, the method includes the step of: providing the label with a message ring memory for at least two data packets.

By means of the message ring memory, at least two data packets are advantageously stored, they can be used for identity verification.

The method preferably includes the step of: transmitting the data packet only after the expiry of a predetermined waiting time period which is different from a waiting period of at least one other label.

This advantageously means that a plurality of labels and / or the data communication center are not simultaneously each transmit a data packet and thereby interfere with the individual data packets with each other.

It is preferred that the method comprises the steps of: checking prior to the start of transmission of the data packet, whether parallel time another data packet can be received; If the check shows that another data packet is time-parallel receivable before the start of transmission of the data packet, then re lapse let the waiting period and re-transmitting the data packet.

This advantageously means that a plurality of labels and / or the communications hub Datenkom- not simultaneously send each data packet and thereby interfere with the individual data packets with each other.

Preferably, the method comprises the steps of: when sending the data packet receiving the same through the one label and checking whether the transmitted data packet is complete and / or error-free; If the check shows that the transmitted data packet is incomplete and / or erroneous, then re lapse let the waiting period and re-transmitting the data packet.

Thereby, the error rate during transmission of the data packet by the respective label is advantageous minimal.

Preferably, the method comprises the step of: checking the data packet by means of a CRC check sum method.
