Description

[0001] The invention relates to a craftsman's equipment and a method for user-related management of craftsman's equipment by means of a craftsman's equipment token.

[0002] Conventional handheld tools are directly controlled by the user. For example, a drill is controlled by the user inserting a suitable drill bit and then pressing a button on the drill. If a user without specialized knowledge performs a delicate task using such a handheld tool, it can lead to incorrect operation, an undesirable result, and a risk to operational safety.

[0003] Document US 2017 / 177894 A1 discloses a craftsman's equipment according to the preamble of claim 1.

[0004] DE 10258900 A1 discloses a cordless screwdriver for tightening screw components, comprising a screwdriver motor supplied with electrical voltage by a self-contained power supply located on the screwdriver, and at least three measuring devices for monitoring screw parameters during the screwing process, namely a torque sensor with which the tightening torque generated by the screwdriver motor can be measured, a rotation angle sensor with which the current screw-in angle can be measured from a predetermined measuring position, and a current sensor with which the drive current of the screwdriver motor can be measured. Furthermore, monitoring electronics are provided which switch off the screwdriver motor if the tightening torque, the screw-in angle, and the drive current are each within a predetermined, assigned target parameter window.

[0005] Especially when performing difficult or unusual processing tasks using a handheld device, conventional handheld devices reach their limits.

[0006] It is an object of the present invention to enable the operation of a handheld device in a simple, safe and error-resistant manner.

[0007] This problem is solved by the articles with the features according to the independent claims. Further embodiments are shown in the dependent claims.

[0008] According to an embodiment of the present invention, a craftsman's equipment is provided, comprising a plurality of craftsman's tools, at least some of which have a mechanical receiving device for mechanical coupling with a mechanical coupling device of a token, and the token with a processor and with the mechanical coupling device for selective mechanical coupling with a respective mechanical receiving device of the respective craftsman's tool, wherein the craftsman's tools comprise at least two different elements from a group consisting of the following elements: an electric handheld device; a tool or a tool set; a storage system; a consumable; and a vehicle.

[0009] According to a further embodiment of the invention, a method for user-specific management of craft equipment is provided by means of a token of a craft equipment with the features described above, wherein the method comprises a mechanical coupling of the mechanical coupling device of the token with a mechanical receiving device of a selected craft equipment, and after mechanical coupling has taken place, a control of the coupled craft equipment by means of the processor of the token.

[0010] Within the scope of this application, a "token" can be understood, in particular, as an identification mark that can establish a functional link between the token and a tool. Such an identification mark can be used in a coupled system, which may include the token, a tool mechanically coupled to it, and optionally one or more additional devices or nodes. In particular, a token can be a hardware component for identifying and / or authenticating a user to whom the token may be assigned. A token can be an electronic token and, for example, provide a processor-related control, monitoring, and / or communication function.

[0011] For the purposes of this application, a "craftsman's tool" can be understood to mean, in particular, a device used by a craftsman during a craft activity. This may include, in particular, an electric hand tool (such as a cordless screwdriver), a (especially non-electric) tool (such as a hammer, pliers, a file, a screwdriver, or a drill), a tool set with several tools or tool elements (such as a drill bit box or a bit box), a storage system (such as a toolbox), consumables (such as anchor bolts or a box of screws), and / or a vehicle (such as a motor vehicle in which a craftsman can transport his equipment to a work site, a forklift, or a tool trolley), and / or other craftsman's equipment (such as a ladder).A tool can also be a battery pack or an adapter between a battery pack and a processing device (for example, a drill module of a power drill). For instance, a token can be inserted into such a battery pack or adapter.

[0012] Within the scope of this application, a "handheld device" can be understood to mean, in particular, a portable device that can be manually operated and carried by a user and with which a craft task can be performed, for example, the preparation of a substrate. Advantageously, the handheld device can be an electric handheld device that can be operated by means of an electrically generated driving force. Such an electric handheld device can be controlled by means of electrical control signals – in particular provided by means of a token. In particular, a hole can be drilled in a substrate by means of a handheld device by applying a driving force in the form of a longitudinal force and / or a torque, and / or a driving force in the form of a longitudinal force and / or a torque can be applied to a fastening element to be installed in a substrate.For example, a handheld tool can be designed to drive the rotation of a machining device, such as a drill bit and / or a fastener. Examples of electric or motorized handheld tools include a cordless screwdriver, a cordless drill / driver, a rotary screwdriver, an impact driver, a ratchet screwdriver, a drill, an impact driver (especially a cordless impact driver), and a hammer drill.

[0013] For the purposes of this application, "craftsman's equipment" can be understood to mean, in particular, a set comprising a variety of tools that a craftsman uses in combination to carry out craft tasks. For example, a craftsman's equipment set can include at least ten, and in particular at least one hundred, tools.

[0014] Within the scope of this application, the term "processor" can be understood to mean, in particular, an electronic entity that may contain an arithmetic unit and / or a control unit and / or be configured for data processing. Specifically, such a processor can exert a controlling influence on a tool mechanically coupled to the token and thereby configure the operation or operating mode of the tool (especially a handheld device). Specifically, the processor can control the configuration of the operation or operating mode of the tool or a part thereof, particularly based on a user profile of a token user. The control logic between the token and the tool and / or between the token and another node (especially another node or a central control unit) can, for example, be implemented according to a master-slave architecture or a peer-to-peer architecture.The token's processor can alternatively or additionally perform other functions, for example, evaluating sensor signals from a sensor of the token, controlling communication with another node via a communication network, etc. A processor can be implemented, for example, by a processor component, a plurality of processor components, or a part of a processor component.

[0015] Within the scope of the present application, a "mechanical receiving device of a tool" can be understood, in particular, as a structural provision on a tool that is geometrically and preferably also in terms of communication technology adapted to a mechanical coupling device of a token that is to be mechanically coupled to the mechanical receiving device. For example, the mechanical receiving device can be a receiving opening designed for the positive-locking and / or friction-locking reception of a token or a part thereof. Advantageously, the mechanical receiving device of the tool and the mechanical coupling device of the token can be adapted to each other in such a way that, when a mechanical coupling is formed between the mechanical coupling device of the token and the mechanical receiving device of the tool, a communication link or...A control connection is established between the token and the receiving device. For example, forming a positive-locking connection between the mechanical receiving device and the mechanical coupling device can simultaneously lead to the formation of an electrically conductive coupling between the token and the tool, for example by creating a connection between the electrical contacts of the token and the tool. Electrical control signals can then be transmitted from the token to the tool via such electrical contacts.It is also possible that by forming a mechanical connection between the mechanical receiving device and the mechanical coupling device, a contactless transponder (for example, an RFID tag) of the token is brought within a readability range of a transponder reader (for example, an RFID reader) of the tool, so that control signals can then be wirelessly transmitted from the token to the tool.

[0016] For the purposes of this application, a "tool" can be understood to mean, in particular, a hand tool (for example, a hammer, pliers, a file, a screwdriver, or a chisel) or a machining tool (for example, a drill bit, a bit, or a milling cutter) that is or is to be inserted into an electric handheld device (for example, a machine tool). A tool may preferably be non-electric. However, a tool may be inserted into an electric handheld device.

[0017] Within the scope of the present application, a "tool set" can be understood to mean, in particular, an arrangement of several tools or tool elements, especially of the same tool type. In such a tool set, the several tools or tool elements can be held in a common tool holder. For example, a tool set can be a drill box with several different drills or a bit box with several different bits.

[0018] Within the scope of this application, a "storage system" can be understood to mean, in particular, a device or an arrangement of devices for holding a large number of electrical hand tools, tools and / or tool sets, consumables, etc. In particular, such a storage system can be designed as a shelf, case, drawer, etc.

[0019] For the purposes of this application, "consumable goods" can be understood to mean, in particular, parts that can be arranged individually or as a group of jointly packaged parts in a common package and are consumed by a tradesperson during a trade activity and are therefore continuously replenished. Such consumable goods can include, for example, screws, dowels, nails, anchor bolts, and the like, which are frequently stored as a group in a common package, especially when the consumable goods are configured as C-parts.

[0020] For the purposes of this application, a "vehicle" can be understood to mean, in particular, a device that is movable, especially by means of wheels, and which can be moved by applying a motive force. Specifically, a vehicle can be a motor-driven vehicle, for example, one powered by an electric motor and / or an internal combustion engine. Examples include passenger cars, trucks, construction vehicles (e.g., excavators), forklifts, etc. Alternatively, a vehicle can be moved by muscle power, for example, a workshop trolley pushed by a user.

[0021] Within the scope of the present application, the term "at least two different elements from a group consisting of an electric hand-held device, a tool or tool set, a storage system, a consumable and a vehicle" can be understood in particular to mean that at least two different elements from the five elements "electric hand-held device" (A), "tool or tool set" (B), "storage system" (C), "consumable" (D) and "vehicle" (E) are included in the craftsman's equipment.This includes, in particular, the configurations A + B and optionally C and / or D and / or E, A + C and optionally A and / or D and / or E, A + D and optionally B and / or C and / or E, A + E and optionally B and / or C and / or D, B + C and optionally A and / or D and / or E, B + D and optionally A and / or C and / or E, B + E and optionally A and / or C and / or D, C + D and optionally A and / or B and / or E, C + E and optionally A and / or B and / or D, and D + E and optionally A and / or B and / or C. Furthermore, at least one additional element (for example, auxiliary equipment such as ladders, scaffolding) can optionally be part of the tradesman's equipment.

[0022] According to an exemplary embodiment of the invention, a tool set is created in which several different, highly diverse, or diversified, tools can each be mechanically coupled to a token. Such a mechanical coupling can be achieved using a mechanical receiving device for the tool or a corresponding mechanical coupling device for the token. With a universally applicable token, which can be detachably coupled to any tool, each tool can be selectively equipped with a token function in a user-defined manner. For example, a token with processor resources can be mechanically coupled to a tool designed as an electric handheld device in order to control the electric handheld device using the token's processor.For example, controlling an electric handheld device via the token's processor can be done in accordance with a user's authorization profile, thus enabling, preventing, or customizing user access to the device. Alternatively or additionally, a token with processor resources can be used to track the location of a tool mechanically attached to it. This makes it possible, for instance, to locate misplaced or lost tools or consumables using the token. For this purpose, a token can be equipped with a tracking function or linked to a tracker.Furthermore, it is possible to mechanically couple a tool to a token in order to enable communication between the tool and a communication network, for example, to communicate with a node in the communication network. By connecting a token to a communication network, it may also be possible, for example, to trigger a reorder of consumables in a stockpiling system when the remaining stock falls below a critical level.A token that is universally applicable due to its mechanical coupling device and its processor resource can be reversibly coupled to any of a plurality of craft tools of a complex craft equipment via a universal mechanical interface in the form of their mechanical receiving device in order to equip a respective craft tool with a token functionality.

[0023] Further exemplary implementation examples of the craftsman's equipment and the procedure are described below.

[0024] According to an exemplary embodiment, the tool set can include at least one additional token with another processor and a mechanical coupling device for optional mechanical coupling with a respective mechanical receiving device of another tool set. For example, each of a multitude of tools set can be equipped with a corresponding token. Advantageously, each token can be equipped with a processor that can be configured according to a function of the respective token.Advantageously, according to an exemplary embodiment of the invention, for a tradesman's equipment with very different types of tools, a set of tokens (each with processor resources) is provided, wherein each of the tokens can provide a specific function with respect to the respective tool simply by forming a mechanical coupling with it. This creates a modular system that can be scaled as needed and provides efficient control and / or monitoring functions.

[0025] According to an exemplary embodiment, the token can have a communication device, and at least one other token can have a further communication device. Furthermore, the tokens can be interconnected by means of these communication devices, in particular directly or via a node of a communication network. Thus, different tokens assigned to different tools can be interconnected. For example, the interconnected communication of a first token, attached to an electric hand tool that must be used with personal protective equipment, with a second token, attached to said personal protective equipment, enables the first token to detect the use of the personal protective equipment by the user, based on its communication with the second token.

[0026] According to an exemplary embodiment, the token can be configured to control the respective tool by means of the processor when the mechanical coupling device is mechanically coupled to the mechanical receiving device of the respective tool. Within the scope of the present application, a "mechanical coupling device" can be understood, in particular, as a physical structure of the token that can be coupled, for example, by positive locking and / or friction locking with a corresponding physical structure of a tool in order to form a temporary and well-defined mechanical connection between the token and the tool. For example, the token can be inserted into a correspondingly shaped receiving opening of the tool in order to mechanically couple the token and the tool.The mechanical coupling device can be configured to establish a communicative connection between the token and the handheld device by forming a mechanical linkage with the device. The token's processor can interpret this mechanical linkage as a user's request to operate the device and can trigger a comparison of the user's personalized user profile with the mechanically linked device. This trigger logic allows for a very rapid authorization check and grants the user access to the device if the personalized user profile permits it.

[0027] According to an exemplary embodiment, the token can be designed as a disk, in particular a circular disk, with a diameter in the range of 1 cm to 10 cm, particularly in the range of 2 cm to 5 cm. It is also possible for the token to be designed as a cuboid (in particular a flat cuboid) with an edge length in the range of 1 cm to 10 cm, particularly in the range of 2 cm to 5 cm. A token designed as a small disk can be easily carried by a user and allows for a space-saving mechanical coupling with a tool. Furthermore, designing the token as a circular disk with the aforementioned dimensions allows for the implementation of a sensor, in particular a fingerprint sensor, on a surface of the token to identify a user of the token.For self-identification, which may be a prerequisite for establishing a controllable link between the token and the tool, a user can simply place their finger on the fingerprint sensor. Once identified, the token can then be used to verify the identified user's authorization to control the tool linked to it. After successful verification, control can begin; if verification fails, control can be blocked.

[0028] According to an exemplary embodiment, the mechanical coupling device can be designed to allow the token to be removed from the tool after mechanical coupling. In this way, a user wishing to use a tool can mechanically couple their assigned token to the tool and remove the token again after use. The tool can be designed to allow control of the tool by the token, or even use of the tool, only while a mechanical coupling with the token exists.

[0029] According to an exemplary embodiment, the mechanical coupling device can have an electromechanical interface, in particular a universal electromechanical interface for different power tools. An electromechanical interface can be understood here as a connection where the formation of a mechanical link between the mechanical coupling device of the token and a corresponding mechanical receiving or connecting device of the power tool simultaneously results in the formation of an electrical link between the token and the power tool. Then, for example, a positive-locking coupling of the token and the power tool enables the transmission of an electrical control signal from an electrical contact of the token to an electrical contact of the power tool. Such a power tool setup is particularly robust in operation.

[0030] According to an exemplary embodiment, the token can be configured to establish a communication link, particularly a contactless or contact-based communication link, with the tool when the mechanical coupling device is mechanically coupled to the tool. Referring to the previously described embodiment concerning an electromechanical coupling between the token and the tool, contact-based electrical communication between the token and the tool can preferably only be enabled after the mechanical connection has been established. This allows the user to retain control through an intuitive connection process. Alternatively, a contactless communication link between the token and the tool can only be established after a mechanical coupling has been established.For example, only when the token is inserted into the tool can a wireless transponder (e.g., an RFID tag) of the token be brought within a readable range of a transponder reader (e.g., an RFID reader) on the tool. This can be achieved, for example, by using a short-range communication protocol (e.g., NFC, near field communication) for wireless communication between the token and the tool.

[0031] According to an exemplary embodiment, the token can include a communication device configured for communication via a communication network, in particular via the public internet, an intranet, and / or a mobile network. Specifically, the token can be configured for cryptographic communication using a cryptographic unit within the token. Such a communication device can, for example, include a transmitting and / or receiving antenna and an associated processor resource, enabling, for example, wireless communication with one or more other nodes of such a communication network, in accordance with a communication protocol of the communication network.In this way, the token can communicate unidirectionally or bidirectionally with one or more other nodes, beyond simply controlling a mechanically coupled tool, for example, to download and / or upload information. For instance, downloading information from a communicatively coupled node to the token could involve downloading a user profile or a workflow control—a task to be performed by a user with a tool mechanically coupled to the token. Similarly, uploading information from the token to a communicatively coupled node could involve uploading tracking data, enabling the monitoring of the token's operation and / or the operation of a tool coupled to it for documentation and / or quality control purposes.

[0032] According to an exemplary embodiment, the token can be configured to communicate with at least one communicatively coupled node of the communication network via the communication device. This node is selected from a group consisting of another token, a portable user device with an app stored on it (which may be configured to communicate with a token), a central control unit (for example, for centrally managing or controlling tools in a tradesman's equipment), and a reordering unit for reordering consumables for operating a tool. According to one embodiment, multiple tokens can communicate with each other.For example, a first token can be mechanically linked to a first tool (such as a handheld device like a hammer drill), and a second token can be mechanically linked to a second tool (such as personal protective equipment like safety glasses). If, for example, the use of personal protective equipment is mandatory for operating the handheld device, its activation can be made contingent on communication between the two assigned tokens documenting that the user of the handheld device assigned to the first token is wearing the personal protective equipment assigned to the second token. It is also possible for a user to control a tool from a portable user device (such as a mobile phone) equipped with appropriate software, and thus from a remote location.For this purpose, the user device and the token can communicate with each other via a communication network. If necessary, the token can also use resources of the user device, such as a camera resource, to control the tool. Furthermore, it is possible for a central control unit to manage a large number of decentralized tools, for example, using user profiles that allow individual users of the decentralized tools to use specific tools in a user-specific manner. In other words, user profiles can be stored at a central control unit.If a token mechanically linked to a power tool is intended to enable its use by a user identified by the token, the token can, through communication with the central control unit, gain access to the associated user's profile and only permit that user to use the tool if their use is consistent with their user profile. For example, the use of a chainsaw could be made contingent upon a user possessing the appropriate qualifications or training, as documented in their user profile. Furthermore, a token mechanically linked to a power tool could also detect a need to reorder consumables and transmit this information to a connected reordering system.For example, such a token can be mechanically coupled to a container holding consumables and can detect the successive removal of consumables from this container (e.g., via sensors). For instance, if the remaining stock of consumables falls below a predefined threshold, a reorder can then be triggered by the token, either through direct or indirect communication between the token and the reordering system.

[0033] According to an exemplary embodiment, the token can be configured to download a data set from a communicatively coupled node of the communication network via the communication device, in particular a data set defining an operating sequence of the craft tool and / or a data set defining a user profile of a user of the token. A communicatively coupled connection can be, for example, wired (e.g., electrical via at least one electrical cable or optical via a fiber optic cable) or wireless (e.g., by transmitting electromagnetic radiation, such as visible light, infrared light, or radio frequency radiation).The aforementioned and / or other data can be stored centrally within the communication network, for example, at a central control unit for controlling or managing a large number of tools, thus ensuring efficient resource utilization. When needed, a decentralized token—for example, mechanically coupled to a tool—can retrieve the data from the central control unit or another node via the communication network. By retrieving a data set defining an operating sequence of the tool, the token can receive control information to operate the tool accordingly and subsequently control the tool as required.For example, installing a fastener (such as a screw) in a substrate may require applying a specific torque, the value of which the token can retrieve via the communication network. It is also possible that a user identified by the token is subject to certain restrictions regarding the use of a tool mechanically coupled to the token, so that the token only permits a specific user to use a tool in accordance with a corresponding user profile, which the token can download via the communication network.

[0034] According to an exemplary embodiment, the token can be configured to upload a data record, in particular a data record containing operating results and / or operating parameters of the tool's operation, to a communication-capable node of the communication network via the communication device. For example, a processing task carried out using a tool (e.g., setting a fastener into a substrate) can be documented in the form of a data record and transmitted as operating results to a node of the communication network (e.g., a central administration or control unit). This allows for subsequent tracking for documentation and / or quality assurance purposes.As an operating parameter related to the processing of a machining task, for example, the actual torque applied by a cordless screwdriver when screwing in a screw can be transmitted.

[0035] According to an exemplary embodiment, the processor can be configured to control the operation of the craftsman's device coupled with the token in accordance with a personalized user profile stored in or accessible to the token, in particular in accordance with a personalized user authorization profile of the user of the token.Within the scope of this application, a "personalized authorization profile of a user with regard to a craft tool" can be understood in particular as a data record specifically related to a user, which assigns to this user specific rights of use (for example, the right to use a hand tool if the user has received appropriate instruction or possesses a corresponding license), restrictions of use (for example, the right to use only a hand tool that does not exceed a certain maximum weight, or if the user wears associated personal protective equipment) and / or prohibitions of use (for example, a prohibition of using a hand tool if the user has not received appropriate instruction or does not possess a corresponding license) in the context of the use and / or management of a particular craft tool or craft equipment.The authorization profile may contain a specific assignment of authorizations, authorization restrictions and / or authorization prohibitions to specific craft equipment.

[0036] According to an exemplary embodiment, the processor can be configured to allow, configure, and / or prevent the use of a particular tool by the user, based on their personalized authorization profile, when paired with that tool. According to an exemplary embodiment of the invention, a token can control a mechanically coupled tool in a user-specific or user-related manner. For example, triggered by the establishment of a mechanical coupling between the token and the tool, the user can then be granted access to the tool, denied access, or the manner of use can be regulated in accordance with the personalized user profile.By assigning a user-specific authorization profile to individual tools within a tradesperson's equipment, even complex systems with a large number of tools, tokens, and users can perform a quick and robust comparison between user profiles and tools using a user-specific token, thus achieving efficient access management. At the same time, a high level of operational reliability can be achieved, as the efficient management of authorizations is possible even with a vast number of tools, users, and tokens.

[0037] According to an exemplary embodiment, the token can include an identification device for identifying a user of the token. Within the scope of this application, an "identification device for identifying a user of the token" can be understood, in particular, as an entity or functional block of the token that provides information for establishing the identity of the user of the token. An identification device can, for example, identify a user using sensor data indicative of a user's identity (such as sensor data from a fingerprint sensor) and / or by means of appropriate user input (for example, entering a user ID, optionally in combination with a password).As part of the user identification process, the identification device can, in particular, perform a comparison between determined sensor data (for example, actual fingerprint data) and predetermined reference data (for example, target fingerprint data).

[0038] According to one exemplary embodiment, the processor can be configured to only enable the operation of the tool linked to the token if prior user identification via the token has confirmed that the identifying user is authorized to operate the tool. According to another exemplary embodiment, operation of the tool without linking to the token can be prevented. Without positive verification of a user's authorization to use a specific tool, its use can be deactivated. If a user presses a button on a drill without or before verification of their authorization, the token's processor prevents the drill from operating.The requirement for a user to positively confirm their authorization to use a craft tool increases operational safety and prevents misuse.

[0039] According to an exemplary embodiment, the tools may include at least one electric or motorized handheld device. This may, for example, be comprised of a group consisting of a drill, a cordless screwdriver, a cordless drill / driver, a rotary screwdriver, an impulse screwdriver, a ratchet screwdriver, an impact wrench, in particular a cordless impact wrench, a hammer drill, a corded handheld device, and a pneumatic handheld device.

[0040] According to an exemplary embodiment, the tool can be designed as a tool from a group consisting of a hammer, pliers, a file, a screwdriver, a drill, a bit, and a socket for a ratchet. A tool set can, for example, be a bit holder with bits stored therein or a drill holder with drill bits stored therein.

[0041] According to an exemplary embodiment, the storage system can be designed as a storage system consisting of a group comprising a case, a shelf, a drawer, and a box.

[0042] According to an exemplary embodiment, the consumable can be designed as a consumable from a group consisting of a screw, a dowel, a bolt anchor, a nail, a rivet, and a package containing such consumables.

[0043] According to an exemplary embodiment, the vehicle can be designed as a vehicle from a group consisting of a motor-driven vehicle (in particular electrically and / or by means of an internal combustion engine) and a muscle-powered vehicle (for example, a tool trolley).

[0044] According to an exemplary embodiment, the craftsman's equipment can include at least one electric handheld device, at least one tool and / or at least one tool set, at least one storage system, at least one consumable, and at least one vehicle.

[0045] Exemplary embodiments of the present invention are described in detail below with reference to the following figures. Figure 1shows a craftsman's equipment with craftsman's tools and tokens according to an exemplary embodiment of the invention, which are coupled in a communication network with additional communicative nodes. Figure 2 shows a token with an associated storage and recharging device according to an exemplary embodiment of the invention. Figure 3 shows a token according to an exemplary embodiment of the invention, Figure 4 shows components of a craftsman's equipment according to another exemplary embodiment of the invention. Figure 5 shows a craftsman's equipment with craftsman's tools and a token according to an exemplary embodiment of the invention, which are coupled in a communication network.

[0046] Identical or similar components in different figures are provided with the same reference numerals.

[0047] Before exemplary embodiments of the invention are described with reference to the figures, some general aspects of embodiments of the invention will be explained.

[0048] According to an exemplary embodiment, a token can be used for use with a craft tool (for example, a machine tool).

[0049] The token can, for example, be provided with a combined electrical and mechanical structure. More precisely, different tokens within a token array can share a common basic electrical and / or mechanical structure but differ in terms of variable additional electrical and / or mechanical components. As fixed components, different tokens within a token array can include a processor (which can, for example, also perform post-processing and / or data compression tasks), a communication device, and a cryptographic unit (in particular, a decryptor). A variable component of different tokens within a token array can, for example, differ in terms of at least one transmit / receive unit, at least one antenna, and / or at least one sensor.Each token can be designed as an object that may include a packaging component, one or more slots, battery compatibility, and / or a conductor adapter. It is also possible for a token to be powered externally. According to an exemplary embodiment, a token system can perform (particularly indirect) control of a power tool using an authorization concept, especially a personalized authorization concept.

[0050] Tokens within a token array can have different levels of functionality and are therefore assigned to different generations. For example, a first-generation token might be equipped with processor-based or communication-based capabilities, such as a BLE-enabled token with limited sensor functionality (e.g., only a temperature and a vibration sensor). Such a token could, for instance, be used to download datasheets from a central node in a communication network. The execution of a task using a tool assigned to a token could, for example, be made dependent on the current ambient temperature. For instance, the insertion of a chemical anchor might only be permitted if a minimum processing temperature is ensured. A second-generation token might, for example, be equipped with processor-based or communication-based capabilities.A third-generation token can be designed for communication as an ultra-wideband token, which can also be equipped with a gyroscope. For example, such a gyroscope can detect when a handheld device (such as a drill) falls to the ground and automatically switch it off. A third-generation token can, in turn, be equipped with NB-IoT (Narrowband Internet of Things) functionality and a GPS sensor. A third-generation token can thus determine the location of the token and a mechanically coupled tool and only authorize the operation of the tool if the determined location is authorized for its intended use. For example, the operation of an excavator can only be authorized if the excavator is located on a specific construction site. This provides protection against misuse.

[0051] According to an exemplary embodiment of the invention, a token forms a basic unit of a system for the controlled operation of power tools. Such a token can have a fixed component (in particular with a microcontroller, decrypter) that can be included in every token of a token arrangement. Furthermore, each token of a token arrangement can enable an electromechanical connection to power tools (in particular, provide one or more electrical contacts for electrical coupling with a power tool). In addition, tokens of a token arrangement can have a variable component that can differ for different tokens. Such a variable component can equip a token with one or more sensors (for example, fingerprint sensor, gyroscope, GPS sensor, UWB sensor, temperature sensor), at least one radio chip (for example, configured according to Bluetooth Low Energy, Bluetooth, NB-IoT, LTE Cat. 1).M, 5G, NFC) and / or at least one antenna (for example, configured according to 2.5 GPS, BLE, UWB, NB-IoT). Optionally, a token can be equipped with its own power supply, such as a battery or rechargeable battery.

[0052] One or more tokens with the described properties can form part of a system for tradespeople's equipment, which can also include tradespeople's tools (such as cordless drills, tools, cases, shelves, etc.). Software components (for example, IoT cloud software, an app, etc.) can also be part of such a system.

[0053] Preferably, a token according to an exemplary embodiment of the invention has a mechanical coupling device, which may be designed as an electromechanical coupling. This mechanical coupling device can be plugged into or onto electromechanical couplings of power tools (such as hand tools, implements, cases, shelves, etc.). It is also possible to attach a mechanical coupling device of a token to or into a housing provided for this purpose (for example, a tracker) or to or into other devices (for example, a device for refilling empty aerosol cans, etc.).

[0054] In operation, a token can communicate with the tool or other device into which it is inserted. This allows the token to determine which device it is attached to. Therefore, a standardized bus for all devices is advantageous. This ensures that in a complex system of tools and equipment (such as a company's machinery or equipment), every token can be mechanically and communicatively connected (especially control-wise) to every tool. More generally, all tools in a set of equipment can be equipped with a mechanically identical connection device, all of which allow for optional coupling with the same token. In other words, the token can be modularly plugged into all these devices.

[0055] According to one exemplary embodiment, a token can transmit documents and / or control signals to the power tool (for example, a cordless drill) into which the token has been inserted. Alternatively or additionally, a token can download documents relating to an accessory connected to a handheld device (for example, a tool, an adapter, etc.). A token can also download documents relating to a workpiece to be processed with a power tool (for example, a concrete anchor) and thus control the power tool accordingly (for example, controlling the speed for drilling and / or driving a concrete anchor).

[0056] Ideally, a token can download permissions for a tradesperson's equipment (for example, a handheld device, tool, case, shelf, etc.) so that the equipment can only be used within a specific geographical area (for example, drills only on a construction site). For this purpose, a GPS sensor can be implemented in the token or the associated equipment, providing current location information.

[0057] In particular, according to an exemplary embodiment of the invention, a token can download authorizations for a piece of equipment (for example, a handheld device, tool, case, shelf, etc.) so that the equipment can only be used or operated by specific persons (for example, only trained personnel). The token can, in particular, download authorizations for the equipment so that the equipment can only be operated with specific personal protective equipment.

[0058] A token can control a mechanically linked power tool, for example, switching a vacuum cleaner on or off. For instance, when a drill is switched on, the token can also trigger the activation of a dust extraction system, so that the user doesn't need a separate hand to switch on the vacuum cleaner.

[0059] According to one embodiment, a token can be equipped with an optical sensor (for example, a camera or a laser scanner) to identify a product or body (for example, a wall or a screw) being processed with a craft tool.

[0060] It is also possible that the token downloads product information from a communication network node to which it is connected. The token, or a mechanically coupled tool, then knows how to process the product, for example, what torque to apply.

[0061] According to one embodiment of the invention, different types of power tools (in particular, electric hand tools such as impact drills, tools or tool sets such as drill bits or drill bit boxes, storage systems such as shelves, consumables such as screw packs, and / or vehicles such as forklifts) are mechanically coupled to a respective token (which includes a processor). The token assigned to a particular power tool can also be detachably exchanged between different power tools and is therefore universally applicable.The token's processor enables a wide range of functions, such as controlling an associated power tool, enabling communication between different tools via their tokens, connecting a tool token to a communication node (for example, to upload and / or download data, or to trigger a reorder of consumables), or locating or tracking tokens and their associated tools. The described architecture is particularly well-suited for a diverse system of numerous tools within a tradesperson's equipment and allows for efficient management with minimal effort.

[0062] For example, according to an exemplary embodiment of the invention, the described system can efficiently support a tradesperson in fulfilling a task. For instance, a tradesperson might be tasked with driving a concrete screw into a substrate using a cordless screwdriver. To do this, a user can first be identified using a token on the cordless screwdriver, and it can be verified whether a personalized authorization profile of the identified user permits their use of the cordless screwdriver. If this is successfully verified, the type of screw or other consumable used, such as M8 screws, can be detected, for example, by a camera on the token, the cordless screwdriver, or a mobile device paired with the token.To assist the user in setting the detected consumable, a specification of a setting operation can then be downloaded from a database in a communication network using the token of the cordless screwdriver and processed using the cordless screwdriver.

[0063] According to an exemplary embodiment of the invention, a craftsman's equipment is managed as a work environment for a craftsman, comprising several craft tools or other components, which may include, for example, electric hand tools, hand tools, cases, shelves, and the like. Each of these components or craft tools may have an electromechanical interface for a token. Similarly, a token may have an electromechanical interface for connecting to the electromechanical interface of the craft tools or other components.

[0064] For example, the token can communicate with an assigned tool or other component so that it knows which tool it is plugged into. The token can then control the assigned tool or other component. It is also possible for the token to download documents from a communication network (such as the internet or an intranet), for example, as a basis for controlling the assigned tool or other component. Advantageously, the token can be modular and interchangeable between different tools or components. It is also possible for the token to be controlled by the tool or other component it is assigned to.To enable wireless communication, the token can be equipped with a wireless connection to the internet or an intranet (in particular by providing a WLAN antenna, SIM card, etc.). Advantageously, the token can have a communication link to one or more tools, especially via a wireless or wired connection. Preferably, the token can be modularly interchangeable and integrated into different tools. For this purpose, the token can be equipped with an electromechanical interface that is identical for all tokens and can therefore be flexibly coupled to the universal electromechanical interface of any tool.

[0065] A token according to an exemplary embodiment of the invention can download documents from a communicatively coupled node and / or upload documents to a communicatively coupled node via a communication network.

[0066] According to a preferred embodiment, the token can load authorizations into a user system for craft equipment and the like from a cloud and, if authorization is lacking or only limited for a user, block or restrict the use of a craft device for that user.

[0067] A token can be designed in various versions with different levels of functionality, as illustrated by the following examples. For instance, a first-generation token might only support Bluetooth communication and include a temperature sensor and a vibration sensor. A second-generation token might additionally offer NB-IoT functionality and include a gyroscope. Further token functionality is possible, such as a GPS sensor, a UWB module, a fingerprint sensor, etc.

[0068] For example, a token can communicate with an app running on a user's device. This can enable the identification of a tool being used (such as a drill), for instance, via the user's device camera. Similarly, a workpiece or consumable, such as a concrete anchor, can also be identified. Based on the information gathered, the tool and consumable can be controlled and processed accordingly.

[0069] When a token is equipped with communication capability, it can be made communicative in connection with a gateway, another token, etc.

[0070] A token according to an exemplary embodiment of the invention can also provide theft protection. For this purpose, the token can be equipped, for example, with a fingerprint sensor, a facial recognition sensor, or the like to identify a user. Only an authorized user can be granted access to use the associated tool. For example, a machine can only be operated with a correspondingly authorized token.

[0071] Authorization for a token can be stored on the token itself and / or in the cloud. A token can download an authorization profile for a user, for machines used by that user, and for tools used by those machines. Furthermore, a token can save these authorizations locally after each download so that they are available offline. Alternatively or additionally, authorizations can be stored on a machine or battery. In this case, the user then identifies themselves at the machine and / or battery.

[0072] Permissions can also include user-specific data. For example, if a machine is too heavy for a user, that machine can be locked for that user.

[0073] According to one embodiment, a token can be inserted into a tracker. The tracker can be attached to a machine, for example by gluing, magnetic connection, or by snapping into place. The token is then inserted into the tracker. For example, the tracker can have a battery and antennas for RFID and / or WLAN and / or Bluetooth.

[0074] Figure 1 shows a craftsman's equipment 104, for example a workshop equipment or a machine park or craftsman's equipment of a company, with craftsman's tools 102 and tokens 100 according to an exemplary embodiment of the invention, which are coupled in a communication network 120.

[0075] More precisely, the craftsman's equipment 104 comprises a variety of tokens 100, which, for example, can all be shaped and dimensioned in the same way. In Figure 1Only two such tokens 100 are shown, however, a much larger number of tokens 100 is possible in a craftsman's equipment 104 (for example, at least ten, in particular at least one hundred).

[0076] Furthermore, the craftsman's equipment 104 includes a number of craftsman's tools 102. Figure 1Only two such tools 102 are shown; however, a much larger number of tools 102 are possible in a tool set 104 (for example, at least ten, in particular at least one hundred). Some or all of the tools 102 can have an identically shaped and dimensioned mechanical receiving device 152, here designed as an insertion or receiving opening, which is designed for mechanical coupling with a respective mechanical coupling device 110 of any user-selected token 100. A positive-locking connection can be formed between each mechanical coupling device 110 of each token 100 and each mechanical receiving device 152 of each tool 102 by plugging them together.

[0077] When a mechanical connection is formed between a token 100 and a selected tool 102 by inserting the mechanical coupling device 110 of the token 100 into the receiving device 152 of the selected tool 102, a functional or communication connection is simultaneously established between the token 100 and the tool 102. More precisely, in the illustrated embodiment, an electrical connection is formed between one or more electrical contacts 156 on an outer surface of each token 100 and one or more corresponding electrical contacts 136 on an inner surface of each receiving device 152 of each tool 102.The formation of a positive connection between a respective token 100 and a respective receiving device 152 of a tool 102 thus leads to the formation of an electrical contact and therefore an electrically conductive connection between the token 100 and this tool 102. This electrical connection also establishes an electrical communication link between the token 100 and the tool 102, which in particular enables the transmission of electrical signals (e.g., control signals). Alternatively to this contact-based electrical coupling, a wireless or...A contactless communication connection between a token 100 and a craft device 102 is established by inserting the token 100 into the receiving device 152, thereby bringing a transponder (for example, an RFID tag, not shown) of the token 100 into a readability range of a transponder reader (for example, an RFID reader, not shown) of the craft device 102 (not shown).

[0078] A token 100 is advantageous when, by being inserted into the receiving device 152 of a tool 102, it has been brought into communication with the tool 102 and is thus configured to control this tool 102. Operation of the tool 102 in a state without being paired with the token 100 may be prevented. In other words, the tool 102 can only be used after a successful pairing of token 100 and tool 103.

[0079] By allowing each token 100 to be optionally coupled with any mechanical receiving device 152 of a selected craft tool 102, a flexibly combinable, modular system for operating, controlling and / or managing craft tools 102 in a complex craft equipment 100 is created.

[0080] In Figure 1The hand tools 102 are shown only partially and schematically. For example, a first part of the hand tools 102 may be designed as electric or motor-driven hand tools, such as electric drills, electric cordless screwdrivers, etc. Hand tools 102 designed as electric or motor-driven hand tools may, for example, have a functional device 134, which performs the actual function of the respective hand tool and can be driven by an electric or motor drive. In a hand tool 102 designed as a drill, the functional device 134 may, for example, be a drill chuck (especially with a drill bit). In a hand tool 102 designed as a cordless screwdriver, the functional device 134 may, for example, be a bit holder (especially with a bit).Furthermore, a handheld device can have a power supply unit 142, for example, a removable and rechargeable battery pack. Such a power supply unit 142 can supply the functional unit 134 with electrical drive energy during operation. Alternatively or additionally, the power supply unit 142 can also supply a token 100 with electrical energy when it is received in the receiving unit 152. A handheld device can also have a control unit 138, which can be configured to control the handheld device (for example, when a handheld device is not coupled with a token 100) and / or to interact with a processor 106 of a coupled token 100.

[0081] A second part (not shown) of the craftsman's equipment 102 can be designed as (especially non-electric or non-motorized) tools or tool sets, for example as screwdrivers, drills or drill boxes, bits or bit boxes, etc.

[0082] A third part (not shown) of the 102 craftsman's equipment can be designed as a storage system for hand tools, implements, and consumables. Examples of such storage systems are boxes, cases, drawers, and / or shelves for holding or storing hand tools, implements, and / or consumables.

[0083] A fourth part (not shown) of the craftsman's equipment 102 can be designed as consumables, for example boxes with screws or dowels, or as bolt anchors.

[0084] A fifth component (not shown) of the 102 set of tools can be designed as motorized vehicles, for example, cars or trucks, forklifts, and / or excavators, as used in carrying out craft tasks. Manually powered, non-motorized vehicles, such as a pushable tool cart, can also be used.

[0085] A sixth part (not shown) of the craftsman's equipment 102 may be designed as other aids and equipment of the craftsman's equipment 104, for example as ladders, scaffolding, etc.

[0086] Some or all of the described craft equipment 102 can be temporarily or permanently equipped with a token 100.

[0087] The advantage of the 102 hand tools for pairing with the 100 tokens is that the use of a 102 hand tool paired with a 100 token by a user can be authorized, configured, and / or blocked based on a personalized authorization profile. More precisely, a user of a 100 token can be assigned a user profile that can contain information regarding that user's ability and authorization to use specific 102 hand tools, but can also define usage restrictions and / or prohibitions for certain 102 hand tools.Such a user profile can be stored in a storage device 128 of a token 100, in a storage device 140 of a craft device 102 and / or in a database 132 of a node (in the illustrated embodiment a central control device 124, alternatively another node) that is coupled to the token 100 via a communication network 120.

[0088] The structure of Token 100, which is in Figure 1as detailed below. The aforementioned token 100 serves, for example, for user-specific control of a selectable tool 102 from the tool set 104 and has a processor 106 for this purpose. For example, the processor 106 can be embedded inside the token 100 and thus protected. The processor 106 can, for example, be designed as a microprocessor. It is possible to design the processor 106 as part of a processor unit, as an entire processor unit, or as a plurality of interacting processor units. The processor 106 of the token 100 serves for control-related interaction with various tools 102 from the tool set 104, and in particular, it interacts functionally with a selected tool 102 into whose receiving device 152 the token 100 is inserted.

[0089] Furthermore, the token 100 contains a cryptographic unit 108, which supports cryptographic communication between the token 100 and a communication partner device in the communication network 120. For example, such encrypted communication, supported by the cryptographic unit 108, can take place between the token 100 and a central control unit 124, a user terminal 122, and / or a reordering unit 126. This encrypted communication increases data security when communicating via the communication network 120.Optionally, encrypted communication between the token 100 and a mechanically coupled handheld tool 102 can also be carried out using the cryptographic unit 108, for example, when transmitting control signals from the token 100 to a handheld tool 102. This ensures secure control of the respective handheld tool 102, as it prevents hacking or unauthorized external control.

[0090] As already mentioned, the token 100 has the mechanical coupling device 110, which is designed for preferably positive mechanical coupling with a receiving device 152 of one of the various craft tools 102 of the craft equipment 104. The mechanical coupling device 110 of the token 100 is defined by its external shape, which is the inverse of the internal shape of a receiving device 152 of a respective craft tool 102.

[0091] Advantageously, the Token 100 can be configured to control the operation of a selected power tool 102 by means of the processor 106 (and optionally the cryptographic unit 108 using cryptographic communication) when the mechanical coupling device 110 is mechanically coupled to a receiving device 152 of said power tool 102. More precisely, the processor 106 of the Token 100 can control the power tool 102, and in particular its functional unit 134, so that the desired processing task is carried out by the power tool 102 as intended. For example, the processor 106 of the Token 100 can specify the torque applied by a drill bit of a power tool 102 configured as a drill to a substrate in which a borehole is to be drilled.

[0092] Advantageously, the token 100 can be configured for user-specific control of the tool 102, particularly based on a personalized authorization profile of the user. For this purpose, the token 100 can be equipped with an identification device 170, which is configured to identify a user of the token 100. The identification device 170 consists of a sensor 112, configured, for example, as a fingerprint sensor, and the part of the processor 106 that identifies the user from sensor data acquired by the sensor 112, for example, by pattern matching with reference data. More precisely, the sensor 112 is configured, for example, as a fingerprint sensor, onto which a user places a finger for identification. Advantageously, the sensor 112 can therefore be located in a surface area of ​​the token 100.Sensor 112 can then determine whether the data it captures indicates that the user is authorized, and if so, which user it is. This determination can be made by comparing the sensor-captured data with sensor reference data (for example, a fingerprint of an authorized user stored in a database).

[0093] The aforementioned storage device 128 of the token 100 can store information that is indicative of, or grants access to, a personalized authorization profile of the user with respect to the craft device 102. More precisely, the storage device 128 of the token 100 can store a data record that represents or maps an authorization profile of a user (or multiple authorization profiles of multiple users). However, it is also possible that the authorization profile of one or more users is stored in an entity located remotely from the token 100, for example, in a central database 132 of a central control unit 124, to which the token 100 can be communicatively linked via the communication network 120.To access a user's authorization profile, it may then be sufficient to store access information (for example, a link to the central database 132, possibly in combination with a password) in the token 100 to access the remotely stored authorization profile.

[0094] Processor 106 can be configured to control the operation of the tool 102 paired with token 100 in accordance with the user authorization profile of the token 100's user. Specifically, processor 106 can be configured to only allow the operation of the tool 102 paired with token 100 if prior user identification via token 100 has resulted in the identification of a user who is authorized to operate the tool 102. Advantageously, processor 106 of token 100 can therefore be configured to permit, configure, and / or prevent the user's use of the tool 102 based on the personalized authorization profile when paired with it.For example, a processing task requested by a user using a tool 102 might only be permitted for certain users, such as those who have received specific training or special qualifications (e.g., a driver's license) for using the tool 102. If the user's authorization profile does not meet such a condition, the processor 106 of the token 100 can prevent the use of the tool 102. Conversely, if the user's authorization profile does meet such a condition, the processor 106 of the token 100 can permit the use of the tool 102. If, due to an authorization profile, certain processing tasks are only permitted for a user to a limited extent, the user's use of the tool 102 will only be permitted if a corresponding condition is met.For example, a user may only be permitted to use a tool 102 if they are wearing protective equipment (such as safety glasses). If such protective equipment is also indicated by a token 100, the processor 106 can search for a communicatively linked token 100 that indicates protective equipment, and only allow the user to perform the desired task once the presence of protective equipment has been detected by the presence of such a token 100.

[0095] As in Figure 1As shown, the tool set 104 can have a token arrangement 130 consisting of a plurality of tokens 100, with different tokens 100 exhibiting different levels of functionality. For example, the tokens 100 of a tool set 104 can be divided into first, second, and third generation tokens 100. Each token 100 of any generation can fulfill the basic function of a token 100, as described above. Tokens 100 of higher generations can also have additional functions and / or added convenience, but also support the basic function of a token 100 of the lowest generation. Tokens 100 of all generations can have the same shape and can be used with any tool tools 102 of the tool set 104. In other words, the token arrangement 130 is compatible with different generations of tokens 100.The craft tools 102 do not require any adaptation with regard to their interaction with a token 100 of a given generation, except that a receiving device 152 is provided for the mechanical receiving of a corresponding token 100.

[0096] Each of the Token 100 used can, for example, be designed as a plug-in element for insertion into a receiving opening of a power tool 102. For example, each Token 100 can be designed as a circular disc with a diameter ranging from 2 cm to 4 cm, making it easy for a user to handle and space-saving to insert into a power tool 102. Other shapes of Token 100 are possible; see, for example, Figure 3Furthermore, the mechanical coupling device 110 of each token 100 is designed to detachably couple the token 100 to the tool 102. Thus, a user can use a token 100 (assigned to them, for example) successively in combination with different tools 102, whereby the selection of an addressed tool 102 can be effected simply by mechanically inserting the mechanical coupling device 110 of the token 100 into a corresponding receiving device 152 of a target tool 102. Therefore, the mechanical coupling device 110 of a token 100 serves as a universal electromechanical interface for different tools 102.

[0097] As already mentioned, the Token 100 can have one or more sensors 112, including the user identification sensor described above. Alternatively or additionally, the Token 100 can be equipped with, for example, a gyroscope, a location sensor, and / or a temperature sensor. A gyroscope can detect, for instance, if a tool 102 containing the Token 100 falls and is consequently subjected to a shock. In this case, the tool 102 can be switched off as a precaution to prevent user injury and damage. A location sensor (for example, a GPS sensor) of the Token 100 allows the current position of the Token 100 and the tool 102 to be determined.The use of a 102 tool can be restricted (for example, in a user profile) to a specific area (such as a particular construction site), for instance, to prevent misuse. If a location sensor detects that a 102 tool, along with its token 100, is located in an unauthorized area, the token 100's processor 106 can switch off or deactivate the tool to prevent misuse. A temperature sensor on the token 100 can measure the ambient temperature. If a task (for example, setting a chemical anchor) is only permitted under certain temperature conditions, the 102 tool can be prevented from operating for safety reasons if a temperature condition is not met based on the temperature sensor data.

[0098] Optionally, the Token 100 has a power supply unit 116, for example, a replaceable battery or a rechargeable battery. In this case, the Token 100 can be operated autonomously. Alternatively or additionally, the Token 100 can be supplied with electrical energy by a power supply unit 142 of a power tool 102 when the Token 100 is inserted into the receiving device 152.

[0099] Figure 1The figure further shows that the token 100 can have a communication antenna 114, for example, a WLAN antenna. It is also possible, and advantageous for diversity, for the token 100 to have multiple communication antennas 114 that, for example, support different communication protocols. For instance, a communication antenna 114 can be implemented in the form of a planar coil, preferably arranged in a surface area of ​​the token 100. A communication antenna 114 can be configured as a transmit / receive antenna. It is also possible to provide a transmit antenna and a separate receive antenna, or only one of these antennas.

[0100] Furthermore, the in Figure 1The depicted token 100 represents a communication device 118, which can be formed by the interaction of the communication antenna 114 with a corresponding part of the processor 106 and optionally with the cryptographic unit 108. The communication device 118 serves to enable the token 100 to communicate with one or more communication nodes via the communication network 120. This network can be, for example, the public internet, an intranet, or a mobile network.

[0101] For example, the token 100 can communicate with another token 100 of the work equipment 104 via the communication network 120 – or directly. This can be done, for example, to detect the presence of protective equipment equipped with a token 100 (which, for reasons of occupational safety, can be made a condition for authorization to use a work tool 102).

[0102] Alternatively or additionally, it is possible to establish a communicative connection between the token 100 and an app or other software stored on a portable user device 122 via the communication network 120. In the illustrated embodiment, the user device 122 is a mobile device with a user interface that allows a user to control and / or monitor the communicatively connected token 100 and / or a connected tool 102. Using the user device 122, a user can also control and / or monitor the tool 104 from a remote location. For example, a token 100 can connect to the user device 122, which is configured here as a mobile device, via an app. Data, such as a user profile of a user of the user device 122, can be downloaded to the token 100 using the user device 122.Furthermore, it is possible that the token 100 accesses resources of the user terminal 122 during operation, for example, a processor contained therein and / or a camera of the user terminal 122.

[0103] For example, a camera integrated into the user terminal 122 can be used to capture an image of product packaging that allows conclusions to be drawn about a consumable (for example, a type of screw) used for a processing task. This information can be transmitted from the user terminal 122 to the token 100, enabling the token 100 to control a tool 102 (e.g., a cordless screwdriver) to drive the corresponding screw. More generally, an optical detection device, in particular a camera, can be provided on the token 100 and / or on the user terminal 122. This device is designed to detect processing information relevant to a processing task to be performed by the tool 102.Advantageously, the processor 106 can be configured to perform the processing task using the detected processing information.

[0104] Alternatively or additionally, it is possible to establish a communicative link between the token 100 and a central control unit 124 (for example, for controlling several power tools 102) via the communication network 120. The central control unit 124 can be equipped with access rights to a database 132 from which data records can be transmitted to the token 100. Such data records could, for example, be a user profile requested by the token 100, an operating data record for executing a processing task with a power tool 102 mechanically coupled to the token 100, etc.Thus, the token 100 can be configured to download a data set, in particular a data set defining an operating sequence of the craft device 102 and / or a data set defining a user profile of a user of the token 100, by means of the communication device 118 from the central control device 124 or another communicatively coupled node of the communication network 120.

[0105] Furthermore, it is possible, through the communicative coupling between the token 100 and the central control unit 124, to transmit data from the token 100 to the control unit 124 for storage in the database 132. Such data could, for example, be tracking data that allows the tracking of a tool 102 coupled to a respective token 100. Thus, the token 100 can be configured to upload a data record, in particular a data record containing operating results and / or operating parameters of the tool 102, to the control unit 124 or another communicatively coupled node of the communication network 120 via the communication unit 118.

[0106] Finally, it is possible that the token 100 is linked via the communication network 120 to a reordering device 126 for reordering consumables for operating a power tool 102. If a token 100 detects (for example, by means of a token-specific sensor 112, such as an optical one, and / or by means of a camera image from the user device 122) that the remaining stock of a specific consumable (for example, a specific type of screw for driving into a substrate using a power tool 102 designed as a cordless screwdriver, into which the token 100 is inserted) has fallen below a critical threshold, the token 100 can inform the reordering device 126 accordingly via the communication network 120 and thereby trigger a reorder of this consumable.The reordering device 126 can be a computer, which in turn can be connected to supplier nodes via the communication network 120 to execute the reorder. A reorder of consumables can therefore be triggered by a token 100, for example, if the token 100 and / or a tool 102 has detected, for example, via sensors, that the remaining stock of certain consumables has fallen below a predefined threshold.

[0107] In the operation of the tradesman's equipment 100, user-specific control of a tradesman's device 102 via a token 100 can first be achieved by identifying the user of the token 100 using the sensor 112, which is designed as a fingerprint sensor. Subsequently, the mechanical coupling device 110 of the token 100 can be mechanically coupled with the mechanical connection device 152 of the selected tradesman's device 102. Before or after the mechanical coupling, a personalized authorization profile of the token 100 user can be located, for example, in one of the storage devices 128 or 140. After successful mechanical coupling, the tradesman's device 102 can be controlled by the processor 106. Advantageously, the use of the tradesman's device 102 by the user can be authorized, blocked, and / or configured based on the personalized authorization profile.In particular, the processor 106 can be configured to only enable the operation of the power tool 102, which is linked to the token 100, if a user identification performed beforehand using the token 100 has resulted in the identification of a user who is authorized to operate the power tool 102. The personalized authorization profile can contain at least one piece of information from a group consisting of a prohibition of use for at least one defined operating mode of the power tool 102 based on user qualifications and / or physical (e.g., a physical disability) or biological (e.g., advanced age) user characteristic; a user-specific permission to use at least one defined operating mode of the power tool 102; and, for example, a condition of use related to occupational safety for the use of the power tool 102.For example, the authorization profile for a specific user may include information that, due to their physical constitution (e.g., age, height, and / or weight), the user is only authorized to use power tools up to a certain weight (e.g., up to 20 kg). Furthermore, such an authorization profile for a specific user may specify which power tools the user is authorized to operate (e.g., a user may only be permitted to use a forklift if they have a forklift operator's license). Additionally, a user profile may specify which personal protective equipment (e.g., work coat, ear protection, safety glasses) a user must wear to operate a particular power tool and / or a specific piece of power tool.The use of a tool 102 can be denied to a user by token 100 until the personal protective equipment (PPE) on that user has been detected (e.g., by sensors). For example, the PPE itself can also be equipped with a corresponding token 100, so that the presence of PPE on the user can be verified through token-token communication.

[0108] The processor 106 can be configured, when paired with the tool 102, to allow or prevent the download of a data set (for example, a data sheet), in particular a data set defining an operating procedure of the tool 102, from a communication network 120, based on the personalized authorization profile. For example, an optical sensor (in particular a camera) of the token 100 and / or on a tool 102 can scan a product package containing screws that are to be inserted into a substrate (for example, a vertical concrete wall) in an operating mode of the tool 102. In this way, it can be sensorily detected, for example, that the screws are M8 screws. The token 100 can then perform or initiate a download of a product specification (as a data set defining an operating procedure) according to the sensor-detected product package.Based on the downloaded data set, the processing task can then be executed without errors by controlling the craftsman's device 102 through the token 100 using the downloaded data set.

[0109] Figure 2 shows a token 100 with an associated storage and recharging device according to an exemplary embodiment of the invention.

[0110] More precisely, the in Figure 2The illustrated token arrangement comprises a token 100 and a token receptacle 150, which can be designed for the form-fitting and / or force-fitting retention of the token 100. For this purpose, the token 100 can be clamped into a receiving space of the token receptacle 150, which is bounded between opposing elastic legs of the token receptacle 150. In this way, a user can mechanically secure the token 100, for example, by using a connecting element 154. Using the connecting element 154, a user can carry the token receptacle 150, optionally with the token 100 retained within it, in a fixed manner, for example, by attaching it to a belt loop.

[0111] It is also possible to attach a token 100 with a fully or partially discharged power supply unit 116 (for example, a rechargeable battery) to the token receptacle 150, thereby triggering a recharging of the power supply unit 116. For this purpose, electrical energy can be transferred from a charging unit 160 of the token receptacle 150 to the power supply unit 116 of the token 100 (for example, via an electrical contact or inductively).

[0112] Figure 3 Figure 1 shows a token 100 according to an exemplary embodiment of the invention. The token 100 according to Figure 3 is designed as a rectangular strip that can be intuitively inserted into an inverted-shaped recess inside a craft tool 102.

[0113] Figure 4 shows components of a craftsman's equipment 104 according to another exemplary embodiment of the invention.

[0114] The craftsman's equipment 104 according to Figure 4 For example, it contains three 102-piece craft tools and three 100-piece tokens.

[0115] The three craftsman tools 102 according to Figure 4 The components are designed as a drill (top), a sensor module (middle), and a battery pack (bottom) and can be connected to each other. During operation, the battery pack supplies the drill with electrical power, while the sensor module detects operating data from the drill (and uses this data, for example, as a basis for control). Bidirectional signal coupling (i.e., transmitting and receiving) is possible between the drill and the sensor module, as indicated by the two arrows. Similarly, bidirectional signal coupling is possible between the sensor module and the battery pack.

[0116] Bidirectional signal coupling is also possible between each of the 102 craft devices and each of the 100 tokens. The configuration according to Figure 4 This shows that all components 102 and 100 can communicate with each other on an equal footing. The communication interfaces between components 102 and 100 can, for example, be configured according to a UART (Universal Asynchronous Receiver Transmitter) protocol.

[0117] The tokens 100 shown can form a token arrangement 130 of tokens 100 of different degrees of functionality, wherein each of the tokens 100 of the token arrangement 130 can be mechanically and functionally coupled to any of the craft tools 102.

[0118] Figure 5 shows a craftsman's equipment 104 with craftsman's tools 102 and a token 100 according to an exemplary embodiment of the invention, which are coupled in a communication network 120. Figure 5shows a modularly trained craftsman's equipment 104 in an Internet of Things (IoT) architecture.

All these systems can be incorporated into the token-controlled trade equipment 104.

[0120] According to an exemplary embodiment of the invention, it is also possible to implement a token as a tracker in a tool (for example, a power tool, a battery housing, etc.). This enables the tool to be located. Optionally, at least one sensor or at least one additional sensor can also be integrated into the token, for example, a temperature sensor and / or a humidity sensor.
