Description

Method for updating a logistics taq of a logistics system

The present invention relates to a method for updating a mobile logistics tag of a logistics system, which comprises at least one internet server, a local radio base station and the logistics tag, with the following steps:

- The mobile logistics tag transmits via at least one radio interface in a long-distance radio mode by means of long-distance radio or in a short-range radio mode by means of short-range radio, the short-range radio having a smaller radio range than long-distance radio;

- Outside the radio range of the local radio base station, a long-distance radio connection is established between the logistics tag and the Internet server, via which they communicate with one another;

- The local radio base station is connected to a supply unit for providing a software update and transmits via at least one local radio interface by means of local radio;

- The provision unit transmits the software update intended for the logistics tag to the local radio base station;

- For communication with the radio base station, the logistics tag changes from radio mode to radio mode;

- If the logistics tag is within radio range of the local radio base station, a local radio connection is established between the logistics tag and the local radio base station.

A logistics tag for logistics systems is known from WO 2017/179985 A1, which can be arranged on a pallet in order to track it. The logistics tag has a radio interface by means of which it can communicate with an external receiver. The disadvantage of this is that the logistics tag can only be operated to a limited extent. The object of the present invention is therefore to further develop the state of the art.

The object is achieved by a method for updating a logistics tag of a logistics system and a logistics system with the features of the independent claims.

A method for updating a mobile logistics tag of a logistics system is proposed. The logistics tag is used to track and / or localize goods and / or sets of goods on pallets during a storage, picking and / or delivery process.

The logistics system includes an internet server, a local radio base station and the logistics tag. The logistics system can also include several logistics tags. With the help of the Internet server, data can be stored, which is then available at almost any location. The internet server is a cloud, so the data is always available. The local radio base station is arranged, for example, in a logistics center in order to enable wireless communication in the logistics center. Depending on its size, the logistics center can of course have several local radio base stations.

Furthermore, the mobile logistics tag transmits via at least one radio interface in a radio mode by means of radio or in a radio mode by means of radio. In this case, local radio has a shorter radio range than long-distance radio. For example, the local radio can have a radio range that is in the range up to 100 meters. In particular, local radio has a radio range which, for example, is sufficient to cover the logistics center. In contrast, long-distance radio has a radio range that is higher than that of local radio. The radio range of long-distance radio can be in the range of a few kilometers. The radio The range of the remote radio is so large, for example, that a radio mast and / or a radio base station, in particular a mobile radio mast, is always within radio range. The radio range of long-distance radio is sufficient, for example, to always be in a mobile network. Additionally or alternatively, short-range radio can have a higher bandwidth than long-distance radio, so that data can be exchanged faster over short-range radio than with long-distance radio. The bandwidth of the local radio can be in the range of Mbit / s, for example, whereas the radio can have a bandwidth of a few kbit / s. Additionally or alternatively, short-range radio can have higher energy efficiency than long-distance radio. This can mean that short-range radio has a lower power consumption than long-distance radio. If the logistics tag is operated with a battery or a battery, for example, the logistics tag can be operated using local radio for longer than by radio. This can be due, for example, to the fact that long-distance radio has a higher transmission power than short-range radio. Additionally or alternatively, short-range radio can have a lower latency compared to long-distance radio.

In the method, a long-distance radio connection is established outside the radio range of the local radio base station between the logistics tag and the Internet server, via which they communicate with one another.

The local radio base station is connected to a supply unit for providing a software update and transmits via at least one local radio interface by means of local radio.

The provision unit also transmits the software update intended for the logistics tag to the local radio base station. The software update can be stored and made available by the software manufacturer on the provision unit. The local radio base station can download the software update from the supply unit. For communication with the local radio base station, the logistics tag changes from long-distance radio mode to local radio mode. The logistics tag then no longer communicates via long-distance radio but via local radio, so that at least the higher bandwidth is available.

The change from radio mode to radio mode takes place when the logistics tag is within radio range of the radio base station. A local radio connection is then established between the logistics tag and the local radio base station.

The local radio base station transmits, via the local radio link, the software update received from the supply unit to the logistics tag, with which a software of the logistics tag is updated. The software of the logistics tag can also be a firmware of the logistics tag. The software can also be operating software for the logistics day. The logistics tag is operated and / or controlled using the software.

The local radio base station transmits the software update to the logistics day via the local radio link, that is to say by local radio. At least the higher bandwidth of short-range radio compared to long-distance radio makes it more practical to transmit the software update to the logistics day by means of short-range radio.

If the logistics system comprises several logistics tags, the software update is transmitted to several or all logistics tags. The logistics tags can then update themselves automatically with the software update. The software update can also be sent to the at least one or more logistics tags without the local radio base station receiving feedback as to whether the one or more logistics tags have received the software update.

It is advantageous if the software update for the logistics day is transmitted exclusively via the local radio link. This at least will high bandwidth of the local radio exploited. Additionally or alternatively, the software update is not transmitted via the radio link. Because the radio has a low bandwidth, it takes too long to transfer the software update to the logistics day. By transferring the software update, the logistics tag can communicate via the radio link only to a very limited extent during this time, so that the actual task of the logistics tag, the tracking and / or localization of the logistics tag, is under Circumstances can no longer take place.

It is advantageous if the supply unit transmits the software update to the local radio base station via the local radio interface. As a result, the high bandwidth of the local radio interface can be used, for example, so that the software update is quickly transmitted from the supply unit to the local radio base station. Additionally or alternatively, the provision unit can also transmit the software update to the local radio base station via an additional interface. This additional interface can be, for example, a physical interface, such as a USB interface and / or network interface. This means that the software update can be transferred to the local radio base station, for example, via the USB interface. The additional interface can also be an update interface. This can, in particular exclusively, be provided for transmitting the software update to the local radio base station. The update interface can have the form of a socket for a plug, for example a USB interface, or a radio interface.

Additionally or alternatively, the software update can also be transmitted to the local radio base station via an Internet interface. The software update is then transmitted to the local radio base station over the Internet.

The software update can thus be transmitted indirectly and / or directly from the Internet to the local radio base station. Additional or older natively, the software update can also be transmitted to the local radio base station via an update interface. The software update can thus be wired to the local radio base station, for example by means of the USB interface, and / or without bell, that is to say, for example, via the local radio interface of the local radio base station.

It is advantageous if the Internet server forms the provision unit. The Internet server can be an Internet server from the software manufacturer of the software update. The internet server can additionally or alternatively be the cloud on which the software update is stored. Additionally or alternatively, the Internet server can also be an Internet server of the logistics system on which the software update is stored. This can increase security against unauthorized access.

Additionally or alternatively, a mobile unit can also form the supply unit. The mobile unit can be a laptop, a smartphone and / or a storage unit, such as a USB stick and / or a hard disk. The smartphone and / or the laptop can have their own local radio interface, by means of which they can establish a radio connection to the local radio interface of the local radio base station and can transmit the software update to the local radio base station. The smartphone and / or the laptop therefore only have to be within range for the local radio connection.

Additionally or alternatively, the software update can also be transmitted from the mobile unit to the local radio base station via the additional interface, in particular the Internet interface and / or the update interface.

If the mobile unit is, for example, the storage unit in the form of the USB stick, it only has to be plugged into the local radio base station. The software update is then transmitted to the local radio base station. If the software update is transmitted from the mobile unit to the local radio base station, the software update can also come from the Internet server. For example, the software update is downloaded from the Internet server to the mobile unit, for example the smartphone, the laptop and / or the USB stick, and is transmitted from there to the local radio base station. The software update is thus transmitted indirectly, namely via the mobile unit, from the Internet server to the local radio base station. This is advantageous, for example, if the logistics system and in particular the local radio base station are to remain separated from the Internet, for example in order to prevent unauthorized access by third parties to the logistics system or the local radio base station.

If the software update is transmitted from the Internet server to the local radio base station via the Internet interface, the software update is transmitted directly to the local radio base station.

The local radio base station can exchange data with the Internet server via the Internet interface. The local radio base station can be stationary, so that the Internet connection to the Internet server can be configured via the Internet interface using cables, in particular glass fiber or copper wire. Alternatively, the local radio base station can also be mobile, the Internet connection to the Internet server advantageously also being able to be formed via radio via the Internet interface.

It is advantageous if the software update is divided into several data packets that are sent to the logistics tag one after the other. If a connection breakdown occurs during the transmission of the software update, it is likely that some data packets of the software update have already been transmitted, so that the software update does not have to be transmitted again completely, but only the still missing software packages. The software update can, for example, be in less than ten data kete be transmitted. A data package can only be transferred to the logistics day if the previous data package has arrived successfully. For this purpose, the logistics tag can report the successful receipt of the previous data packet, so that a new data packet is transmitted to the logistics tag.

To make the logistics tag as easy as possible, the logistics tag uses only one radio interface. The single radio interface can have only a single radio chip, which, for example, creates a data transmission signal for a frequency range for the local radio mode or the radio mode. Furthermore, the single radio interface can have a single antenna, which is suitable for being able to transmit data in the local radio mode and in the radio mode. However, it can also be the case that a frequency range for the local radio mode and the remote radio mode is selected such that the transmission is also possible in the modes by means of an antenna.

Frequency ranges in the sub-GHz range and in the GHz range are available. The sub-GHz range includes, for example, frequencies in the range from approximately 800 MHz to 950 MHz. The GHz range covers frequencies from 2 GHz to 5 GHz.

It is advantageous if the radio is formed by means of LPWAN, NB-loT, a mobile radio interface and / or GSM. The radio can have frequencies in the GHz range.

Additionally or alternatively, the local radio can be designed using UWB, Zigbee, active RFID, Bluetooth and / or WiFi. Local radio can also have a frequency range that is in the sub-GHz range. The local radio can use a local, existing and / or proprietary sub-GHz protocol. This allows an existing local radio area to be used. The logistics tag can also have GPS to determine its position.

Additionally or alternatively, it is advantageous if the logistics tag finally transmits with a time delay either in the radio mode or in the radio mode. Switching between radio mode and radio mode can be done so quickly, for example every millisecond, that there is essentially no difference between whether the logistics tag is currently broadcasting in radio mode or in radio mode and that is what it looks like is awakened that radio transmission is carried out simultaneously in the radio mode and in the radio mode.

It is advantageous if the logistics day changes before, during or after entering the radio range of the local radio base station in local radio mode. This allows communication between the logistics day and the local radio base station with high bandwidth and / or with high energy efficiency.

It is advantageous if the logistics tag independently detects the event of entry into the radio range of the local radio base station. As a result, the logistics tag can switch independently from long-distance radio mode to short-range radio mode. For example, the logistics tag can independently recognize that the local radio base station is within radio range because it detects, for example, a radio signal from the local radio base station. The logistics tag can also determine the entry into the radio range of the local radio base station using geodesics. The positions of the local radio base station and in particular the associated radio ranges are stored in the geodesics, for example. For example, if the logistics tag has GPS, the logistics tag can determine when and if it is entering the radio range of a local radio base station. Additionally or alternatively, the logistics tag can also determine its position using the radio link. and whether it is within radio range of the local base station or how far away it is. Alternatively, the logistics tag can be informed of this event by the Internet server via the radio link. This means that this event can be communicated to the logistics day if the logistics day does not recognize it itself.

It is advantageous if the logistics tag or the internet server compares geodetics, in particular position coordinates and / or a radio radius, of the logistics tag with geodesics of the local radio base station in order to know the event of the entry. Geodesists are, for example, information or maps with landscapes, elevations and / or streets. Based on the geodesics, the logistics tag or the Internet server can recognize when or whether the logistics tag is within the radio range of the local base station. If the logistics tag determines its own position using GPS, for example, it can determine whether it is within radio range of a local radio base station and / or how far it is from the radio range of a local radio base station by comparing it with the geodesics. A radio radius of the logistics tag and / or the local radio base station can also be stored in the geodesists. However, the radio radius does not have to be the same in every direction, so that the logistics tag or the local radio base station covers a circular radio area. Obstacles such as mountains can hinder the radio range in this area, so that the radio area is no longer circular. Rather, the radio radius can have a directional dependency. The geodesists can thus contain data about the direction in which the local radio base station has which radio range.

In addition or alternatively, the geodesists can also contain position data from other local radio base stations. Additionally or alternatively, the geodesics can also contain position data from radio base stations. If the logistics tag or the Internet server compares, for example, the radio radii as geodesics of the logistics tag with those of the local radio base station, it can be determined when and / or whether the logistics tag reaches the radio radius of the local radio base station.

The geodesics of various local radio base stations can be stored in the Internet server or in another public database, for example Google Maps, so that they are always accessible.

It is advantageous if a first geographic map with known geodesics of several local radio base stations is stored in a memory of the logistics tag and that the logistics tag collects geodesics of unknown local radio base stations during its journey and integrates these into the stored geographic map. As a result, the stored geographic map of the known local radio base stations can always be expanded with still unknown geographic maps. These will then be available in the future.

It is advantageous if the Internet server has saved a second geographic map and that the first and / or second geographic map is synchronized via the local radio link. The geo maps contain a large amount of data, so that the geo maps can be updated in a very short time using the high bandwidth of the local radio link. The first and / or second geographic map can thus be kept up to date. The first and / or second geographic map then always contains the most current geodetic data via a large number of local radio base stations in a region or at least one country.

The second geo-map stored on the Internet server will usually be the most up-to-date, since this geo-map receives several logistics tags and will therefore be the most extensive.

It is advantageous if, in order to update the mobile logistics tag, a tag ID of the logistics tag via the local radio link to the local radio base station and is transferred from this to the Internet server. If the logistics system includes several logistics tags, the different logistics tags can be identified. The internet server can, for example, maintain a database of which logistics tag is operated with which software. This makes it possible to identify different logistics tags using the tag ID. The Internet server can then selectively send the software updates to the local radio base station.

Additionally or alternatively, to update the mobile logistics tag, a version number of the software of the logistics tag can be transmitted to the local radio base station and from there to the Internet server. This means that the Internet server can immediately decide whether the logistics tag needs the software update.

It is advantageous if the local radio base station automatically reads the tag ID and / or the version number of the software from the logistics tag. Then, for example, the local radio base station can decide whether the logistics tag needs the software update. This can be done, for example, when the local radio base station already has the software update. The local radio base station then takes over the management or control of the update process. The local radio base station is the administrator here.

It is advantageous if the local radio base station requests the tag ID and / or the version number of the software from the logistics tag and the logistics tag then transmits them to the local radio base station. The local radio base station then takes over the management or control of the update process.

The local radio base station is the administrator here.

It is advantageous if the logistics tag automatically transmits the tag ID and / or the version number of the software to the local radio base station. For example, when the local radio connection is set up for the first time the tag ID and / or the version number are transmitted to the local radio base station. Here, the logistics tag or the local radio base station, which now has the tag ID and / or the version number of the software, can take over the management or management of the update process. The logistics tag can also, for example, instruct the local radio base station to obtain the software update from the Internet server. Additionally or alternatively, the logistics tag itself can request and / or download the software update from the Internet server and / or download it from the local radio base station if the software update is already stored on the local radio base station.

It is advantageous if an authentication is transmitted via radio to the logistics tag, with which the logistics tag can check the authenticity of the software update received via the radio. The authentication is, for example, a checksum or a hash value of the software update. Since this authentication is relatively short or small in scope, for example in the range of less than 1 kilobyte or a few kilobytes, it can be transmitted to the logistics tag by radio. If the logistics tag then receives the software update via local radio or has already received the software update, the logistics tag can independently calculate the authentication, for example the checksum, on the basis of the software update. As a result, the logistics tag is only updated if the authentication received via long-distance radio matches the self-calculated authentication based on the software update received. This increases the security to the extent that a third party cannot transfer manipulated or compromised software updates to the logistics day.

Additionally or alternatively, a password can be transmitted to the logistics tag via radio, with which the logistics tag can decrypt an encrypted software update. This also prevents a third party from transferring a manipulated software update to the logistics tag. Security is increased overall by the fact that the authentication and / or the password are transmitted via radio and the software update via radio. A third party would have to monitor both transmission paths and merge this data, which is much more difficult for the third party. This creates a two-way authentication of the software update.

It is advantageous if the Internet server compares the tag ID with a server database and thereby identifies the logistics tag that is in communication with the local radio base station.

It is advantageous if the Internet server compares the version number of the software with an update number of the software update and initiates an update if it deviates. The Internet server then takes over the management or management of the update process. The Internet server is the administrator here.

It is also advantageous if the software update is carried out from the logistics day. The logistics day then takes over the management or leadership of the update process. The logistics tag is the administrator here.

It is advantageous if the logistics tag transmits a log file to the Internet server when it is connected to the local radio base station via the local radio link. The logistics tag can further comprise at least one sensor unit, which comprises an acceleration sensor, orientation sensor, position sensor, an air pressure sensor, a temperature sensor, a humidity sensor, a magnetic field sensor, a brightness sensor and / or RFID transponder. If the logistics tag is moving, it can, for example, record a temperature profile and transmit it to the Internet server. For example, is the logistics tag arranged on goods that need to be refrigerated, such as food or Medication, the log file can be used to prove the cold chain or to identify interruptions.

The log file can also include information about local radio base stations from various logistics centers, warehouses or the like. The log file can, for example, have positions of different, in particular new or still unknown, local radio base stations. This log file can be sent to the internet server. If the log file includes new local radio base stations, the log file can be transmitted to other logistics tags, which then know new local radio base stations.

It is advantageous if the local radio link between the updated logistics tag and the local radio base station is disconnected as soon as the updated logistics tag leaves the radio range of the local radio base station.

Additionally or alternatively, it is advantageous if the updated logistics tag in local radio mode connects to and updates a second logistics tag that is within its own radio range. This means that the software update can be passed on from one logistics day to another, the second, logistics day. The logistics tag can also be updated if it is not within the radio range of the local radio base station, but within the radio range of an updated logistics tag, which therefore has the software update.

It is advantageous if the logistics tag transmits the tag ID and / or version number to the Internet server in radio mode. The bandwidth of the radio mode is not sufficient to transmit the software update, but it is sufficient to transmit the tag ID and / or version number to the Internet server. As a result, the Internet server can already determine whether the logistics tag needs the software update and transmit it to the local radio base station, so that the logistics tag immediately does that Software update can be obtained if it comes within the radio range of the local radio base station.

It is advantageous if the local radio base station transmits the software update to at least one logistics tag and the logistics tag itself, in particular after the software update has been received in full, decides whether it updates its software with the software update. The local radio base station thus constantly sends the software update without receiving or receiving feedback that the logistics tag is operated with outdated software. The logistics tag always receives the software update and can then determine itself whether its software is up to date or not, and in this case update the software with the software update. This is advantageous, for example, if there are several logistics tags in the logistics system. If the local radio base station asked each logistics tag individually whether it needed a software update, it would take too long to update all the logistics tags. Here the logistics day acts as an administrator or is in charge of the update process. The local radio base station is here only the distributor of the software updates.

It is advantageous if the software update is only transmitted to the logistics tag if the signal strength of the local radio connection when transmitting the software update is greater than a minimum value. For example, the minimum value is 20% of a maximum signal strength. This can reduce the risk of connection breaks during the transmission of the software update. "Received Signal Strict Indication" can serve as a decision criterion as to whether the signal strength is sufficient.

Additionally or alternatively, it is advantageous if the logistics tag only starts updating if the signal strength of the local radio link when transmitting the software update is greater than a minimum value. This can reduce the risk of disconnections during the update of the software of the logistics tag, especially if that Transfer from the software update, for example as individual data packets, is carried out in parallel with the update.

A logistics system is also proposed with a plurality of logistics tags, each of which has at least one radio interface, via which they can communicate in a radio mode by means of radio and in a radio mode by means of radio. Local radio has a smaller radio range than long-distance radio. In addition or as an alternative, short-range radio has a higher bandwidth than long-distance radio. In addition or alternatively, short-range radio has a higher energy efficiency than long-distance radio.

Furthermore, the logistics system comprises at least one local radio base station which has a local radio interface with which the local radio base station can communicate with the logistics tags via local radio. The local radio base station can be fixed in place, for example in a logistics or storage center. Alternatively, the local radio base station can also be mobile.

According to the invention, the local radio base station is designed such that the logistics tags can be updated in accordance with one or more method steps of the preceding and / or following description. Additionally or alternatively, the logistics tags are designed such that the logistics tags can be updated in accordance with one or more method steps of the preceding and / or following description.

Further advantages of the invention are described in the following game examples. Show it:

FIG. 2 shows a schematic view of a local radio base station, Figure 3 is a schematic view of at least one logistics tag, egg ner local radio base station and an Internet server and

Figure 4 is a schematic view of at least one logistics tag, egg ner local radio base station and an Internet server.

FIG. 1 shows a schematic view of a logistics tag 1. The logistics tag 1 can be arranged on goods or on goods carriers with a large number of goods in order to be able to track, locate and / or identify the goods. With the help of logistics tag 1, which is part of a logistics system, the goods can be tracked, for example, from an order to delivery to a customer or even during a relocation. Logistics tag 1 can generally be used to automatically control, track, localize and / or identify the flow of goods. On logistics day 1, for example, the article number, number, weight, origin, shelf life, destination etc. of the goods or goods can be stored.

The data on logistics day 1 can be read out, for example with a reading device, so that the goods can be forwarded based on the stored destination. For example, the article number can also be read to find a storage location for the goods in a warehouse. Of course, the storage location can also be stored in logistics day 1. The data can advantageously be read out contactlessly, for example by means of RFID.

Logistics day 1, for example, is the size of a check card and is also correspondingly thin. The logistics day 1 can be glued to a product, for example on the outside of the packaging box, or on a pallet. Alternatively, logistics day 1 is permanently installed with the goods or the pallet. In order to be able to communicate with the logistics tag 1, it comprises a radio interface 4, with the aid of which the logistics tag 1 can radio in a radio mode by radio or in a radio mode by radio. Local radio has a smaller radio range than long-distance radio. For example, the radio range of short-range radio is up to 100 meters, whereas the radio range of long-distance radio is up to a few kilometers.

Additionally or alternatively, short-range radio can have higher energy efficiency and / or higher bandwidth and / or lower latency than long-distance radio.

The logistics tag 1 advantageously has a control unit 5 which controls the logistics tag 1.

The logistics tag 1 is also operated by software that is preferably executed in the control unit 5. The software is, for example, operating software and / or firmware. With the help of the software, for example, the radio interface 4 is controlled during operation of the logistics tag 1.

Furthermore, the logistics tag 1 in this exemplary embodiment has a radio chip 6. In particular, the logistics tag 1 has a single radio chip 6, by means of which a single radio interface 4 can be operated. The only radio chip 6 can thus control the radio mode and the local radio mode. The radio chip 6 preferably operates the radio mode and the local radio mode only with a time delay, i.e. never at the same time. Furthermore, the present logistics tag 1 has a single antenna 7.

The local radio can also be configured, for example, using UWB, Zigbee, active RFID, Bluetooth, WLAN and / or WiFi. The radio can be configured using LPWAN, NB-loT, a mobile radio interface and / or GSM.

Logistics day 1 can also have GPS (Global Positioning System).

Furthermore, the radio interface 4 can radio in the sub-GHz frequency range and / or in the GHz frequency range. The sub-GHz range has frequencies around 900 MHz, for example, whereas the GHz range has frequencies around 2.4 GHz or 5 GHz. If the logistics tag 1 has only one antenna ne 7, it is advantageous if the local and long-distance radio have the same frequency range, so that the antenna 7 can be tuned to this frequency range.

In addition, the logistics tag 1 according to the present embodiment may have a memory 8 in which data can be stored at least temporarily.

The logistics tag 1 can, as is shown here in FIG. 1, also have a sensor unit 9, by means of which measurement data, such as temperature, accelerations, moisture, radiation such as solar radiation, electrical and / or magnetic fields, etc., can be detected . With the aid of a temperature sensor as sensor unit 9, it can be monitored, for example, whether a cold chain of heat-sensitive goods has been kept.

FIG. 2 shows a schematic view of a local radio base station 2. The local radio base station 2 has at least one local radio interface 10, by means of which the local radio base station 2 can radio via local radio. Advantageously, the local radio base station 2 according to the present exemplary embodiment has at least one local radio antenna 11 via which the local radio base station 2 can spark. As an example, the local radio base station 2 of the present exemplary embodiment has three local radio interfaces 10 and three local radio antennas 11 each assigned. As a result, the Nahfunkba sisstation 2 can establish several parallel local radio connections 19. In addition or alternatively, a plurality of local radio connections 19 can also be formed via a local radio interface 10 and a local radio antenna 11. The short-range radio interfaces 10 and the short-range antennas 11 are the same, so that for the sake of simplicity the same reference numbers are used.

Furthermore, the local radio base station 2 has an internet interface 12. Using the internet interface 12, the local radio base station 2 can establish an internet connection 20 to an internet server 3 or can be connected to the internet server 3 (cf. FIG. 3). The local radio base station 2 can be connected to the Internet server 3 by means of fiber or copper cable. This is useful, for example, if the local radio base station 2 is a fixed local radio base station 2. Additionally or alternatively, the local radio base station 2 can also establish a wireless connection with the Internet server 3, i.e. establish a radio connection. This is useful if the local radio base station 2 is mobile.

Furthermore, the local radio base station 2 according to the present exemplary embodiment additionally or alternatively, in particular to the Internet interface 12, has an additional interface, for example an update interface 26. The additional interface can also be referred to as a direct interface, by means of which a connection between the local radio base station 2 and a mobile unit 25 (not shown here) (see FIGS. 3 and 4) can be established. The additional interface, in particular the update interface 26, can for example be a USB and / or network interface to which the mobile unit 25 can be coupled. The update interface 26 can be provided, for example, in particular exclusively, for transmitting the software update to the local radio base station 2.

Furthermore, the local radio base station 2 of the present exemplary embodiment has its own control unit 13 and its own memory 14. The local radio base station 2 thus has a base station control unit 13 and a base station memory 14.

FIG. 3 shows a schematic view of at least one logistics tag 1 a - 1 f, a local radio base station 2 and an Internet server 3. In this exemplary embodiment, several logistics tags 1 a - 1f are shown. Figure 3 also shows a schematic view of the logistics system, which includes at least one logistics day 1 a - 1 f, the local radio base station 2 and the Internet server 3. Features that have already been described in the preceding figures are not explained again here for the sake of simplicity.

In the exemplary embodiments of the following figures, for the sake of simplicity, a logistics day 1 is spoken by means of letters with the reference symbols without further subdivision. If it is necessary for the understanding, one can speak of the logistics tags 1 a, 1 b, 1 c, 1 d, 1 e and 1f, whereby the logistics tags 1 a - 1f are identified by the letters at the reference symbols should be distinguishable.

The logistics tags 1 a - 1 e are arranged here, for example, in a local radio area 23, which is arranged, for example, in a schematically illustrated logistics center 22 or in a warehouse. The local radio area 23 is given, for example, by the radio range of the local radio base station 2 or the radio range of the local radio base station 2 is such that the local radio area 23 is covered. However, the local radio area 23 given by the radio range of the local radio station 2 does not have to be circular. Obstacles can shorten the radio range of the local radio base station 2, so that there can be a directional dependence of the radio range of the local radio base station 2. The local radio base station 2 may have stored its own directional dependence of the radio range as a data set, for example as geodesics, in order to be able to use this data if necessary.

According to the present exemplary embodiment, the local radio base station 2 is arranged in the local radio area 23, and the local radio area 23 can of course be enlarged if there are several local radio base stations 2, so that in particular the complete logistics center 22 is covered with the local radio area 23. If the logistics tag 1 is thus within the local radio area 23, it is also in radio range from at least one local radio base station 2. If there are several local radio base stations 2, these can advantageously be connected to one another by means of an intranet and / or via the Internet.

In the local radio area 23 can be communicated by means of local radio. In particular, the logistics tags 1 a - 1 e in the short-range area 23 can communicate by means of short-range radio (the logistics tag 1 f is not in the short-range area 23 in the present exemplary embodiment). The logistics tags 1 a - 1 e can establish a local radio link 19 in the local radio area 23, that is to say in the radio range of the local radio base station 2, to the local radio base station 2. Here only a few, in particular not all, local radio connections 19 are shown with playfulness between the local radio base station 2 and some logistics tags 1 a - 1 e. Additionally or alternatively, the logistics tags 1 a - 1 e in the local radio area 23 can also establish a local radio connection 19, not shown here. The logistics tags 1 a - 1 e must of course be within mutual radio range.

By means of the local radio link 19 or with local radio, the logistics tags 1 a - 1 e can be used with a higher bandwidth compared to remote radio and / or communicate a higher energy efficiency. In contrast, short-range radio has a smaller radio range compared to long-distance radio.

Furthermore, the local radio base station 2 can establish a first internet connection 20 to the internet server 3 by means of the internet interface 12 shown in FIG. The first internet connection 20 can be formed, for example, by means of glass fiber, copper wire and / or by means of a radio connection, for example LTE.

Furthermore, the logistics tags 1 a - 1 e are arranged in the logistics center 22 on pallets 15a - 15e. Additionally or alternatively, the logistics tags 1 a - 1 e can also be arranged on the goods on the pallets 15a - 15e. The three logistics tags 1 c - 1 e are also arranged on pallets 15c - 15e, which are arranged in vehicles 16a - 16c, whereas the other two logistics tags 1 a, 1 b are arranged on pallets 15a, 15b, which are stored on a shelf, for example.

A remote radio area 24 is arranged outside the local radio area 23.

In the radio area 24 can be communicated by means of radio. It is of course clear that in the local radio area 23 can also be communicated by means of long-distance radio. On the other hand, it is not possible to communicate in the radio area 24 by means of local radio.

A radio base station 17 is arranged in the radio area 24. The radio base station 17 can be a cell phone mast, for example. In the radio area 24, a plurality of radio base stations 17 can also be arranged to ensure the area-wide communication by means of remote radio.

The logistics tags 1 a - 1 f, in particular the logistics tag 1 f here, can use the radio interface 4 to establish a remote radio connection 18 which, according to the exemplary embodiment shown here, to the remote radio base station 17 is trained. The radio base station 17 can establish a second Internet connection 21 to the Internet server 3 according to the exemplary embodiment shown here. As a result, the logistics tags 1 a - 1 f can establish a connection to the Internet server 3 via remote radio. The second Internet connection 21 can also be formed by means of glass fiber and / or copper wire, so that the radio connection 18 via radio and the Internet connection 21 between the radio base station 17 and the Internet server 3 are wired.

In order to keep the logistics day 1 up to date, the software of the logistics day 1 is updated with a software update. A firmware of logistics tag 1 can also be updated. This eliminates errors in the software or firmware, for example, improves the security of logistics tag 1, reduces power consumption and / or enables new functions.

In order to update or update the software of logistics day 1, the software update must be transferred to logistics day 1.

The software update is transmitted from the Internet server 3 to the local radio base station 2. The local radio base station 2 then transmits the software update via the local radio link 19 to the logistics day 1 a - 1 e. Logistics day 1 a - 1 e then updates the software or, for example, its firmware. This is one way of transferring the software update to the local radio base station 2.

Additionally or alternatively, the software update can also be transmitted from a mobile unit 25 to the local radio base station 2. The mobile unit 25 can be, for example, a smartphone, a laptop and / or a storage unit, for example a USB stick and / or a hard disk. For example, the USB stick can be connected to the local radio base station 2, whereupon the software update on the local radio base station is transmitted on 2. For this purpose, the local radio base station 2 can have an additional interface, in particular the update interface 26, in the form of a USB interface.

Additionally or alternatively, the mobile unit 25 can also be designed as a smartphone and / or laptop. The smartphone and / or the laptop can, for example, establish a wireless connection to the local radio base station 2, via which the software update is then transmitted to the local radio base station 2. The smartphone and / or the laptop can, for example, establish a local radio connection to the at least one local radio interface 10 and then transmit the software update to the local radio base station 2.

Additionally or alternatively, the smartphone and / or the laptop can also transmit the software update to the local radio base station 2 via the additional interface, in particular the update interface 26. The additional interface, in particular the update interface 26, can additionally or alternatively also be a wireless interface, i.e. a radio interface. The update interface 26 can, for example, in particular exclusively, be provided for transmitting the software update to the Nahfunkba sisstation 2. This can increase security. In addition, the communication interface for logistics day 1 remains unaffected by the update interface 26 specially designed for transmitting the software update to the local radio base station 2. By transmitting the software update to the local radio base station 2 via the update interface 26, the communication between the local radio base station 2 and the logistics tags 1 is not disturbed.

If the software update with the mobile unit 25 is transmitted to the local radio base station 2, the software update can originate from the Internet server 3. The software update is thus stored by the Internet server 3 on the mobile unit 25 and by this to the local radio base station 2 transfer. The software update is thus transmitted indirectly, namely via the mobile unit 25, from the Internet server 3 to the local radio base station 2. Unauthorized access to the local radio base station 2 at least during the update can thus be prevented.

If the software update is transmitted via the Internet interface 12 to the local radio base station 2 from the Internet server 3, the software update is transmitted immediately.

If the mobile unit 25 transmits the software update to the local radio base station 2, an additional connection 27 between the local radio base station 2 and the mobile unit 25 can be established. This can be implemented, for example, via WLAN, Bluetooth, RFID, etc.

The software update can, for example, only be transmitted to logistics day 1 via the local radio link 19. As a result, the higher bandwidth compared to the radio link 18 is used, so that the software update is transmitted to logistics day 1 more quickly. Additionally or alternatively, the software update is therefore not transmitted via the radio link 18.

In order to determine whether a logistics tag 1 requires the software update due to its outdated software, the local radio base station 2 can query the logistics tags 1 a - 1 e that are in radio range. The local radio base station 2 can, for example, request a tag ID of the logistics tags 1 a - 1 e in order to be able to use these to determine which logistics tag 1 a - 1 e the software update requires. The tag IDs of the various logistics tags 1 can be stored in a list with corresponding version numbers of the current software of the logistics tags 1. Using this list, the local radio base station 2 can determine which logistics tags 1 a - 1 e have outdated software and consequently require the software update. The list can be stored on the local radio base station 2. Additional On loan or alternatively, the list can also be stored on the Internet server 3, for example in a server database, so that the local radio base station 2 compares the software via the first Internet connection 20. In addition or alternatively, the Internet server 3 can also use the list to determine which logistics tags 1 require a software update.

To update the logistics tags 1 a - 1 e, a version number of the software of the logistics tags 1 a - 1 e can additionally or alternatively be requested and transmitted via the local radio link 19 to the local radio base station 2. The local radio base station 2 can then directly compare the version number of the software with the software update and use it to determine which logistics day 1 a - 1 e the software update requires. The local radio base station 2 can additionally or alternatively transmit the version numbers of the software of the logistics tags 1 a - 1 e to the Internet server 3, which then takes over the evaluation.

When the local radio base station 2 requests the tag ID and / or the version number of the software of the logistics tags 1, the local radio base station 2 directs the update process. The local radio base station 2 is thus the leader, leader or administrator.

Additionally or alternatively, the local radio base station 2 can also read out the tag ID and / or the version number of the software of the logistics tags 1 a - 1 e.

It is also advantageous if the logistics tag 1f transmits its tag ID and / or version number of the software to the Internet server 3 via the radio link 18 in the radio area 24. Since the tag ID and / or the version number of the software has a relatively small amount of data, it can be transmitted to the Internet server 3 via the radio link 18. The Internet server 3 can then determine whether the logistics tag 1f located in the remote radio area 24 needs the software update. The Internet server 3 can then transmit the software update to the local radio base station 2, so that the local radio base station 2 can transmit the software update to the logistics tag 1f immediately after the logistics tag 1f has entered the local radio area 23.

FIG. 4 also shows a schematic view of at least one logistics tag 1 a-1 f, a local radio base station 2 and an Internet server 3. For the sake of simplicity, features that have already been described in the previous figures will not be discussed again here.

In the exemplary embodiment shown here, the vehicle 16 drives with the logistics tag 1f into the exemplary logistics center 22. The logistics tag 1f thus changes from the radio area 24 to the local radio area 23. At the time of the transition from the radio area 24 to the local area 23, the logistics tag 1f can still be operated in the radio mode so that it communicates with the Internet server 3 by means of the radio connection 18.

The change from remote radio area 24 to local radio area 23 can be recognized by logistics day 1f itself and logistics day 1f can change from remote radio mode to local radio mode. The logistics tag 1f can radio in the radio mode by means of radio and establish the radio link 19c with the radio base station 2. When changing from the radio area 24 to the local radio area 23, the logistics tag 1f can still have the long-distance connection 18 and the local radio connection 19c for a period of time. When the local radio link 19c is established, the remote radio link 18 can be ended.

The change from the remote radio area 24 to the local radio area 23 can additionally or alternatively be recognized by the local radio base station 2 and the logistics tag 1 f, for example via the Internet server 3, via the two-th Internet connection 21 and the still existing remote radio connection 18 , instruct the user to switch to local radio mode to establish the local radio connection 19c to manufacture. The change from the radio area 24 in the Nahfunkbe area 23 can additionally or alternatively recognize the Internet server 3 and instruct the logistics tag 1f to switch from the radio mode to the radio mode, so that the radio link 18 ends and the Local radio link 19c is established.

The change from remote radio area 24 to short-range area 23 can also be recognized on the basis of geodesics. If the logistics tag 1f has GPS, it can compare its position with position coordinates and a radio range of the local radio base station 2. The logistics tag 1f can thus decide for itself whether it is within radio range of the local radio base station 2.

Additionally or alternatively, the position of the logistics tag 1f can also be determined by means of radio location in order to be able to determine whether it is within radio range of the local radio base station 2.

After the logistics day 1f has established the local radio link 19c, the software update can be transmitted if the logistics day 1f has outdated software.

According to the present exemplary embodiment, the local radio link 19b is established between at least logistics day 1b and logistics day 1c. For example, the logistics tag 1b, which has the local radio link 19a with the local radio base station 2, receives the software update. Logistics day 1b can transmit the software update to logistics day 1c via the local radio link 19b after complete receipt. The logistics tag 1b can also forward the software update to the logistics tag 1c via the local radio link 19b, even while it receives the software update from the local radio base station 2. The software update can be divided overall into data packets and transmitted from the local radio base station 2 and / or a logistics tag 1 to the logistics tags 1. The present invention is not limited to the exemplary embodiments shown and described. Modifications within the scope of the patent claims are possible as well as a combination of the features, even if these are shown and described in different exemplary embodiments.
