Description

TECHNICAL AREA

The present invention relates to a warehouse logistics data determination system for indirectly determining piece goods data. Furthermore, the present invention relates to a method for operating a storage logistics data determination system and the use of energy self-sufficient sensor units on the respective piece goods. In particular, the invention relates to an apparatus and a method according to the preamble of the respective independent claim.

BACKGROUND OF THE INVENTION

In the case of logistical tasks, it is advantageous if as much data as possible, in particular position data, is known with regard to the goods to be relocated or transported. Piece goods, in particular steel / metal coils, are shifted individually in many cases. Not only for locating the respective piece goods, but also for the purpose of determining the destination, time and place of loading or possibly also required after-treatment of the goods as such, comprehensive data on the respective piece goods are of interest. The data of these general cargo should also be able to be recorded individually if possible. What is desired, therefore, is in particular a bearing management system which is practicable to handle and reliable in terms of the piece goods data, if possible without high manual effort.

Warehouse management systems are already in use. For example, the DE 198 33 240 A1 . DE 10 2006 057 643 A1 . DE 10 2009 016366 A1 . DE 10 2006 053 528 A1 . EP 2 629 899 B1 describe individual aspects of such systems. Against this background, on the one hand, there is a need for improved practicability, on the other hand, there is a need for high operational reliability and as flexible as possible applicability, in particular for piece goods in the form of metal coils.

SUMMARY OF THE INVENTION

The object is to provide a device and a method, whereby the storage or the warehouse management can be facilitated in particular of general cargo warehouses. It is also an object to design a warehouse management system so that the highest possible degree of self-sufficiency, operational reliability and / or flexibility in the application can be achieved.

At least one of these objects is achieved by a warehouse logistics data determination system according to claim 1 and a method or use according to the independent method claim. Advantageous developments of the invention are explained in the respective subclaims. The features of the exemplary embodiments described below can be combined with one another, unless this is explicitly denied.

A warehouse logistics data determination system is provided for the indirect determination of data, in particular position data of goods to be stored or stored at a fixed location in a warehouse, in particular heavy goods items, e.g. Steel coils or metal coils with a mass of up to 40t, based on the determination of a corresponding piece goods specific relative position of a gripper unit arranged for gripping and moving the respective piece goods, in particular arranged for gripping from above from the same horizontal position as the piece goods to be gripped, the storage logistics data determination system Arithmetic unit and an associated (first) position detection unit adapted for detecting the position of the gripper unit, in particular horizontal position in or relative to (relative) coordinates of the bearing, and has a coupled thereto or so connected first communication module configured for wireless communication via at least one communication protocol , in particular bluetooth and / or zigbee- and / or Nahfeld- (NFC) - and / or WiFi- and / or NB-IoT communication protocol, which first communication module preferably for mounting / attachment / fixation at the Gripper unit is formed.

According to the invention, it is proposed that the storage logistics data determination system comprise a plurality of energy self-sufficient (mobile or location-independent), wirelessly communicating sensor units adapted for mounting on parcels, the respective sensor unit having an energy store (in particular configured for energy self-sufficiency of the sensor unit for at least two to six months) and a second communication module configured for wireless communication with the first communication module via at least one communication protocol, in particular bluetooth and / or zigbee- and / or Nahfeld- (NFC) and / or WiFi- and / or NB-IoT communication protocol, and wherein the respective sensor unit has a motion sensor and based on a signal of the motion sensor is motion-activatable with respect to communication / transmission of (piece goods) data to the first communication module, namely movement-activatable by switching from a first, energy-optimized passive mode in a second, data-transmitting mode.

This provides a simple way of labeling and tracking (tracking) of the piece goods, especially with regard to stock or storage capacity, especially in bulky general cargo. As a result, for example, a manual readout of barcodes or similar visual labels can be at least partially replaced. This also provides an indirect position determination in a simple manner, based on the known position of the gripper unit. The respective sensor unit does not have to transmit any position data. Although the sensor unit can optionally also have a second position detection unit configured to detect the position of the sensor unit, eg to determine a height position. But at least the horizontal position can be determined indirectly via the gripper unit.

The present invention enables inventory management in a self-sufficient manner by determining (position) data indirectly via motion-activated sensor units that are in communication with a packaged gripper unit when moving in the warehouse.

The technology according to the invention is also based on a concept in which sensors or pure data transmitters are fastened to the load (piece goods), which autonomously activate only under predefined conditions, in particular when changing the height, and in communication with a (in particular mounted on the gripper unit). Communication module with respect to the respective gripper / crane occur, in particular for unilateral or unidirectional data transmission to the crane or to its communication module.

The piece goods data may e.g. designate the place of origin and / or destination of the good, or e.g. the material (e.g., the grade of steel), or the manufacturer, or the buyer.

The warehouse logistics data determination system can also generally be referred to as warehouse logistics data system or as warehouse logistics data collection system or warehouse logistics data delivery system or warehouse logistics data delivery system.

The gripper unit may e.g. be configured as a heavy-duty crane, which can run off the camp in particular according to predefined bearing rows (matrix, rows, columns), ie based on predefined horizontal coordinates (predefined x and / or y coordinates). The corresponding possible x / y coordinates as available storage bins for the respective piece goods can be stored in a storage database (data storage) of the system.

The position detection unit with respect to the gripper unit (first position detection unit) may preferably be based on laser range finding, at least with respect to the x- and y-axis, but optionally also or alternatively on a PLC motor control, based on triangulation based on signals from the sensor units, on GPS Technology and / or on magnetic field technology (or respective sensors). The magnetic field technology (in particular magnetometer) can be implemented in an advantageous manner, in particular in the case of rail systems with rails (displacement of the crane on rails). The laser technology provides the advantage of high flexibility and system independence.

Optionally, the first position detection unit may also comprise a measuring technology or sensor technology from the group of ultrasound, infrared, in particular also with respect to the z-axis.

In particular, the piece goods may be any individual isolated item, in particular heavy-load piece goods, heavy-duty raw material, e.g. a steel coil or a metal collar. The present invention is not limited to heavy loads, although particular advantages may arise in heavy loads due to the manner of storage. The piece goods, however, can e.g. Also be wrapped in foil straw bales on a predefinable, geometrically recorded storage area (field, hall).

According to an advantageous exemplary embodiment, the storage logistics data determination system is set up for autonomous piece goods data acquisition, in particular position data determination in response to movement of the piece goods based on a communication signal comprising piece goods data of the respective motion-activated sensor unit of the piece goods picked up by the gripper unit. This also provides comparatively high flexibility.

The respective sensor unit may have a holding device for fixing the sensor unit to the piece goods, in particular a holding device arranged for fixing the sensor unit to a steel coil. The holding device can also be adapted in terms of the material of the piece goods, in particular metal. For example, the holding device comprises at least one permanent magnet. The holding device may have a contact surface which is geometrically adapted to the piece goods, in particular a planar, planar and / or concave contact surface adapted for planar contact of a plane, planar and / or a convex surface of the piece goods.

The sensor units can, for example, by at least one magnet and / or at least a hook, a clamp or a belt or the like holding device are attached to the piece goods. According to one exemplary embodiment, the movement sensor of the respective sensor unit is set up, for movement activation a movement or change of movement at least with respect to the vertical axis (FIG. z ), in particular also with respect to at least one horizontal axis ( x . y ), in particular with respect to both horizontal axes. This allows activation in response to lifting or de-activation in response to a drop of the piece goods.

According to one embodiment, the respective motion sensor is based on GPS technology and / or on magnetic field technology. The use of GPS sensors can in particular facilitate the detection of a height position or enable it in a particularly accurate manner.

According to one embodiment, the respective motion sensor comprises an air pressure sensor (in particular barometer) and / or an acceleration sensor (in particular accelerometer). The use of an air pressure sensor can ensure high reliability, in particular also with regard to a displacement in the vertical direction ( z ), and provides a high degree of self-sufficiency regardless of the design of the bearing. The use of an acceleration sensor facilitates the detection of movements in the respective spatial axes. The use of a magnetic sensor is particularly useful for detecting changes in the magnetic field, in particular when moving metallic objects or general cargo ( z .B. Coils, metal coils). By means of the magnetic field technology, relative movements and relative positions of the piece goods can be detected in a useful and reliable manner.

According to one embodiment, the respective motion sensor is based on at least one sensor technology from the following group: air pressure technology, GPS technology, magnetic field technology, acceleration sensor technology. In particular, a combination of these technologies can further improve the resilience of the system or data security.

According to one exemplary embodiment, apart from the motion sensor (or apart from motion sensor technology), the respective sensor unit is embodied as a pure data-generator unit without further sensors, that is, as a unilaterally transmitting data-generating unit. This can increase the degree of autarky. The respective sensor unit does not necessarily have to acquire data, but can also only transmit data when activated. This can in particular also optimize energy consumption. Optionally, the communication can also be done bilaterally. However, it has been shown that it may be useful to confine oneself to unilateral transmission, especially to minimize complexity and energy consumption.

It has been found that, especially at very high loads, i.e., only low accelerations, sensing over the air pressure can provide advantages over detection based on acceleration values. Based on the air pressure, a change in altitude (Δz) can be detected even if the cargo is lifted only very slowly, so with almost no noticeable acceleration. At least in a redundant arrangement, an air pressure sensor can therefore further improve system security or measurement data quality.

A waiver of GPS technology, or at least a sensory redundancy with GPS technology, may also have signaling advantages depending on the arrangement of the camp. Depending on what type of piece goods it is, the camp may be shielded by a more or less massive hall, or the cargo itself shields the sensor unit. GPS signals could be affected. In particular, the air pressure technology, regardless of the design of the bearing and regardless of the way and the location of attachment of the sensor unit on the piece goods to ensure a consistently good quality measurement or data security. The air pressure technology can also be used regardless of the type of piece goods and therefore provides great flexibility.

In this case, the position detection unit with respect to the gripper unit (ie, the first position detection unit) may also be based on air pressure technology, e.g. include a barometer. Preferably, the air pressure technology is combined with a laser technology, in particular also with respect to the z-axis, that is, metrological redundancy is provided on the gripper unit. By means of the corresponding laser distance measuring unit (s), the position of the gripper unit can be determined and optionally also verified, in particular also in the manner of a plausibility check. Ultimately, this redundancy also allows a calibration of the air pressure technology.

According to an advantageous embodiment, the storage logistics data determination system is set up for detecting the relative height position of the respective (picked) piece goods relative to the gripper unit for the indirect determination of the position (-sdaten) of the piece goods. This provides a comprehensive characterization of the piece goods, especially with regard to a momentary Height position. For this example, laser technology (distance measurement) can be used. The detection of the height position also allows the detection of the state of cargo in a raised position, in particular in a suspended, floating arrangement under the gripper unit.

According to one exemplary embodiment, the respective sensor unit is set up to transmit the data in accordance with a predefinable transmission pattern in the second mode and / or as a function of a height position. This can allow conclusions about the arrangement of the piece goods relative to the gripper unit.

According to an advantageous exemplary embodiment, the storage logistics data determination system is set up for a warehouse with at least one predefined longitudinal axis path and / or with at least one predefined transverse axis path for arranging the unit load according to a predefined / predefinable grid, in particular along rails or paths. Such structuring of the bearing provides the advantage, in particular in the case of very bulky general cargo, of a simple assignment of the respective piece goods to individual storage bins.

According to an advantageous embodiment, the storage logistics data determination system is configured for a warehouse with parcel in which the respective parcel (in particular floating, hanging on the gripper unit, for example, in ropes, chains or rods) in the same horizontal position as the gripper unit or in a horizontal position with predefined horizontal deviation Horizontal position of the gripper unit by means of the gripper unit is displaced. The invention is also based on the concept of simplifying storage by virtue of a displacement of gripper unit and piece goods in a predefined horizontal relative position relative to one another, whereby a horizontal position can be determined indirectly via the horizontal position of the gripper unit.

According to one embodiment, the position detection unit is configured to continuously detect the position of the gripper unit (tracking). As a result, the tracking of individual worn storage bins can be facilitated.

According to an advantageous embodiment, the storage logistics data determination system comprises at least one input box and / or at least one output box respectively for removing or receiving the respective sensor unit upon import of the respective piece goods into the warehouse or upon export of the respective piece goods from the warehouse out, the respective box is preferably configured to charge a / the energy storage of the respective sensor unit. In this way, a type of circuit for the sensor units can be provided, in particular such that the sensor units can be provided on the input side with a sufficiently charged energy store.

According to one exemplary embodiment, the warehouse logistics data determination system comprises at least one workstation / workstation configured to assign the respective sensor unit to the respective piece goods and configured to reset the respective sensor unit and set up for manually or at least partially automated capture of piece goods import at an input side and / or general cargo export an exit side of the warehouse. By means of the workstation it is also possible to facilitate a systematic linking of the sensor unit and piece goods, in the manner of a systematic marking of the stock.

According to an advantageous embodiment, the warehouse logistics data determination system is designed as a warehouse indoor online localization system (LION), in particular adapted for use in a warehouse by means communicating autonomously and independently of high performance communication networks (e.g. As a result, the degree of autarky can be further increased, especially independent of GPS technology.

The LION warehouse logistics data determination system may be optimized in terms of warehouse data organization in a self-contained, demarcated warehouse, e.g. a warehouse in a hall or from a technical or operational reliability rather difficult to access camp, especially thanks to motion sensors based on air pressure technology.

The aforementioned object is also achieved by a method for operating a warehouse logistics data determination system for the indirect determination of data, in particular position data from stationary to predefinable positions in a warehouse to be stored general cargo, in particular Schwerlaststückgut, eg steel coils or metal coils with a mass of up to 40t, by means of a plurality of energy-autonomous wirelessly communicating sensor units, respectively in a unit-mounted arrangement, in particular in use as a data processing unit in a previously described Lagerlogistikdatenbestimmungssystem, wherein a transmission or detection and transmission of data by means of the respective sensor unit, in particular comprising (relative) position data with respect to the respective piece goods, to a respective unit load and displacing gripper unit or to a corresponding communication module, in a known (absolute) position of the gripper unit, based on wireless communication via at least one communication protocol, from the transmitted data indirectly the data, in particular position data, of the respective piece goods are determined, in particular based on position data of the gripper unit, and wherein the each sensor unit is autonomously motion-activated for transmission, or itself autonomously switched in response to a change in the state of motion, in particular based on a signal from a motion sensor of the respective sensor unit, and in response to a (new) movement from a first, energy-optimized passive one Mode is switched to a second, data-transmitting mode, and / or is switched or switched in response to immobility or to a lack of movement over a predefined period of time from the second mode to the first mode. This results in the aforementioned advantages.

In particular, it has been shown that the following mode of operation is advantageous: the respective sensor unit is activated (in particular woken up from a sleep mode) if the gripper unit already moves the piece goods, and if the sensor unit has already detected a first movement and also a further movement Confirmation of the first movement can capture. This two-stage collection in the form of a plausibility check has energetic advantages. In particular, the sensor unit may be set up to perform a query relating to sensor detection in passive mode at predefined retrieval times, for example every one to five seconds, for example an acceleration, in particular an acceleration in at least one predefined direction ( x . y . z ) and / or an acceleration over at least one predefined or predefinable minimum threshold. If the movement has been registered (be it only Ix or even several times), the sensor unit switches autonomously activated in the active (second) mode, in which in particular a unilateral data transmission takes place. Data acquisition in the sense of data reception from the outside does not necessarily have to take place, therefore it is possible to speak of unilateral data transmission (in particular unilaterally to the gripper unit or to the communication module of the gripper unit).

According to a variant, a time interval is predefined in which the sensor unit must detect a movement at least twice before the switching into the active (transmitting) mode takes place. This detection time interval may be e.g. be predefined to two or three seconds. Optionally, it is possible to send / transmit automatically as soon as a movement is detected. If there is no movement, then it is possible to automatically switch directly to sleep mode.

According to a variant, a time interval is predefined in which the sensor unit carries out the data transmission. This transmission time interval may e.g. be predefined for one or more seconds, or even only a few milliseconds, and also limited by an upper threshold, e.g. five (milliseconds), especially to prevent high energy consumption.

Preferably, the warehouse logistics data determination system is configured to distinguish between at least three types of data (information) and to process or archive these types of data differently, wherein two of the types of information data are detectable independently of the respective sensor unit. First information data relate to the position of the gripper unit and can be detected and provided by means of the corresponding (first) position detection unit. Second information data relate to the arrangement and distribution of the individual piece goods in the warehouse. This data can be maintained or updated by the third information data, which third information data relate to the movement state of the sensor unit (and provided by the sensor unit) and together with the position data of the moving piece goods, corresponding to the (or convertible to the) position data of the piece goods moving gripper unit, allow an image of all cargo in the warehouse. In this case, the gripper unit can also shift a plurality of piece goods.

The data transmission may in particular comprise a transmission of identification data, namely identification data for identifying the respective sensor unit and / or the respective piece goods. The corresponding data can be stored in a data memory of the sensor unit, which data memory is e.g. can be fed manually or automatically, e.g. when the sensor unit is serviced, charged or reassigned. This data feed into the sensor unit can be made independently of the warehouse logistics data determination system.

The capture of data can also be limited to detection of a movement or the beginning or end of a movement. In other words, the respective sensor unit does not necessarily have to detect and transmit position data, in particular since the (relative) position of the respective piece good can also be determined (exclusively or additionally redundantly) indirectly via the known (absolute) position of the gripper unit.

Optionally, switching back to the first mode (energy-optimized mode) may also be dependent on a lack of connectivity to the communication module of the gripper unit. That is, the respective sensor unit may have a connectivity sensor, switch to the first mode in the absence of connectivity, or switch to the second (transmit) mode with newly established connectivity. The connectivity query can be done in addition to the motion query, optionally in the form of a plausibility check. The combined query can ensure a high quality of the evaluation. In particular, even with very tight storage can be avoided that not the correct cargo is analyzed.

The aforementioned object is also achieved by using a plurality of energy self-sufficient wirelessly communicating sensor units in a storage logistics data determination system, in particular in a storage logistics data determination system described above, respectively for indirectly determining data, in particular (relative) position data relating to at least one unit load of a warehouse, by transmission of Data, in particular (relative) position data of the respective sensor unit attached to the piece goods to a respective gripper unit gripping and relocating gripper unit or a moving with the piece goods, in particular attached to the gripper unit communication module, in a known (absolute) position of the gripper unit, based on wireless Communication via at least one communication protocol in a wireless network, wherein the respective sensor unit motion-activated from a first, energy-optimized passive mode in a second, volume switching mode, in particular unilaterally transmissive. This results in the aforementioned advantages. The transmission can also take place in each case at short intervals, in particular energy-optimized at transmission intervals significantly shorter than a shift-definable switching time interval, e.g. Transmit each over a few milliseconds, every second. In the case of (movement) standstill or in the case of immobility of the unit load (missing displacement), it is possible in this case to switch back into the passive first mode, in particular after a predefinable switching time interval, e.g. after one to three seconds.

The description can be completed by the following summary. In the case of logistical tasks, it is advantageous if as much data as possible, in particular position data, is known with regard to the goods to be relocated or transported. Piece goods, in particular steel / metal coils, are shifted individually in many cases. The data of these general cargo should also be able to be recorded individually if possible. What is desired, therefore, is in particular a bearing management system which is practicable to handle and reliable in terms of the piece goods data, if possible without high manual effort. The present invention provides a system by means of which the warehouse management is made possible in a self-sufficient manner, in particular by determining (position) data indirectly via movement-activated sensor units which are in communication with a packaged gripper unit during movement or displacement in the warehouse ,
