Tool equipment featuring a token for user-related control of a tool

Description

[0001] The invention relates to a token for user-related control of a tradesman's device, a tradesman's equipment and a method for user-related control of a tradesman's device by means of a token.

[0002] Conventional handheld devices are controlled directly by the user. For example, a drill is controlled by inserting a suitable drill bit into the device and then pressing a button on the drill. If a user without specialized knowledge performs a delicate task using such a handheld device, incorrect operation, undesirable results, and a risk to operational safety can occur.

[0003] DE 10258900 A1 discloses a cordless screwdriver for tightening screw components, comprising a screwdriver motor that is supplied with electrical voltage by a self-contained power supply arranged on the cordless screwdriver, at least three measuring devices provided for monitoring screwing parameters during the screwing process, namely a torque sensor for measuring the tightening torque generated by the screwdriver motor, a rotation angle sensor for measuring the current screwing angle based on a predetermined measuring position, and a current sensor for measuring the drive current of the screwdriver motor. Furthermore, monitoring electronics are provided, which switches off the screwdriver motor when the tightening torque, the screwing angle, and the drive current are each within a predetermined, assigned target parameter window.WO2006 / 021047 discloses a token comprising a processor and US2017 / 177894 discloses the preamble of claim 1.

[0004] Conventional handheld devices reach their limits, particularly when it comes to difficult or unusual processing tasks using a handheld device.

[0005] It is an object of the present invention to enable operation of a handheld device in a simple, safe and error-robust manner.

[0006] This object is achieved by the subject matter having the features according to the independent patent claims. Further embodiments are shown in the dependent claims.

[0007] According to the invention, a craftsman's equipment is provided according to claim 1.

[0008] According to a further embodiment of the invention, a method for user-related control of the tradesman device by means of a token having the features according to one of claims 1 to 13 is provided, wherein the method comprises identifying a user of the token, finding a personalized authorization profile of the user of the token, and, when the token is coupled to the tradesman device, allowing, setting and / or preventing use of the tradesman device by the user based on the personalized authorization profile.

[0009] In the context of the present application, a "token" can be understood in particular as an identification tag that can establish a functional connection between the token and a tradesman's device. Such an identification tag can be used in a coupled system, which can comprise the token, a tradesman's device mechanically coupled to it, and optionally one or more devices or nodes. In particular, a token can be a hardware component for identifying and / or authenticating a user to whom the token can be assigned. A token can be an electronic token and, for example, provide a processor-related control, monitoring, and / or communication function.

[0010] In the context of this application, a "crafts tool" can be understood, in particular, as a device used by a craftsperson during a craft activity. This can be, in particular, an electric handheld device (such as a cordless screwdriver), a (particularly non-electric) tool (for example, a hammer, pliers, a file, a screwdriver, or a drill), a tool set with multiple tools or tool elements (for example, a drill bit box with drill bits or a bit box with bits), a storage system (for example, a tool case), a consumable (for example, a bolt anchor or a box of screws), and / or a vehicle (for example, a motor vehicle in which a craftsperson can transport their equipment to a job site, a forklift, or a tool cart) and / or other craft equipment (for example, a ladder).A power tool can also be a battery pack or an adapter between a battery pack and a processing device (e.g., a drill module of a drill). For example, a token can be inserted into such a battery pack or adapter.

[0011] In the context of the present application, a "handheld device" can be understood in particular as 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 processing of a substrate. Advantageously, the handheld device can be an electric handheld device that can be operated by means of an electrically generated drive 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 and by applying a drive force in the form of a longitudinal force and / or a torque, and / or a drive force in the form of a longitudinal force and / or a torque can be applied to a fastening element to be inserted into a substrate.For example, the handheld device can be designed to drive a machining device, and thus a drill and / or a fastener, in rotation. Examples of electric or motor-driven handheld devices include a cordless screwdriver, a cordless drill driver, a rotary screwdriver, an impulse screwdriver, a ratchet screwdriver, a drill, an impact wrench (in particular a cordless impact wrench), and a hammer drill.

[0012] In the context of this application, "craftsman's equipment" can be understood, in particular, as a set containing a plurality of craftsman's tools that a craftsman uses in combination to complete craft tasks. For example, a craftsman's equipment set can include at least ten, in particular at least one hundred, craftsman's tools.

[0013] In the context of this application, the term "processor" can be understood in particular as an electronic entity that can contain a computing unit and / or a control unit and / or can be configured for data processing. In particular, such a processor can control a tradesman's device mechanically coupled to the token and thereby adjust the operation or operating mode of the tradesman's device (in particular a handheld device). In particular, the processor can control the setting of the operation or operating mode of the tradesman's device or a part thereof, in particular based on a user profile of a user of the token. The control logic between the token and the tradesman's device and / or between the token and another node (in particular another node or a central control device) can be implemented, for example, according to a master-slave architecture or a peer-to-peer architecture.The processor of the token can alternatively or additionally perform other functions, for example, evaluate sensor signals from a sensor of the token, control 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.

[0014] In the context of this application, "user-related control of a tradesman's device" can be understood, in particular, as control of a tradesman's device that takes into account the specific characteristics of a user of the tradesman's device or uses these specific characteristics of the user as the basis for the control. In particular, the control logic for controlling a tradesman's device can incorporate physical and / or biological characteristics and / or existing and / or missing skills and / or authorizations of a user.

[0015] In the context of the present 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 determining the identity of the user of the token. An identification device can identify a user, for example, using sensor data indicative of a user identity (such as sensor data from a fingerprint sensor) and / or through a corresponding user input (for example, entering a user ID, optionally in combination with a password). When identifying a user, 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).It is also possible to carry out identification using a transponder, for example using an NFC (near field communication) transponder in a mobile device or using a user's RFID (radio frequency identification tag) transponder (for example in a device key).

[0016] In the context of the present application, a "personalized authorization profile of a user with regard to a tradesman's device" can be understood in particular as a data set specifically related to a user which assigns to this user, within the scope of the use and / or management of a specific piece of tradesman's equipment, specific usage rights (for example, the right to use a handheld device if the user has received appropriate instruction or holds an appropriate driving license), usage restrictions (for example, the right to use only a handheld device that does not exceed a certain maximum weight or if the user is wearing associated occupational safety equipment) and / or usage prohibitions (for example, a prohibition to use a handheld device if the user has not received appropriate instruction or holds an appropriate driving license).In this case, the authorization profile can contain a specific assignment of authorizations, authorization restrictions and / or authorization prohibitions to specific tradesman devices.

[0017] In the context of the present application, "information indicative of a personalized authorization profile of the user with regard to the tradesman's device" can be understood in particular as a data set on a token that assigns the user rights of use, restrictions of use and / or prohibitions of use for one or more specific tradesman's devices.

[0018] In the context of this application, "information granting access to a personalized authorization profile of the user with regard to the tradesman's device" can be understood, in particular, as access data that grants a user access to a data set that assigns the user usage rights, usage restrictions, and / or usage prohibitions for one or more specific tradesman's devices, without the data set being completely stored in the token. Such an access option can, for example, be a link (particularly in combination with a password) in a communications network via which the token can retrieve the authorization profile (particularly password-protected). Such an access option can also consist in a token being able to retrieve the personalized authorization profile from a tradesman's device that is mechanically linked to the token, if this mechanical link exists.

[0019] According to an exemplary embodiment of the invention, a token can control a linked tradesman's device in a user-specific or user-related manner. For this purpose, the token can first identify a user in order to then consider a personalized authorization profile of the identified user with regard to the tradesman's device selected for the desired use as the basis for controlling the tradesman's device. In particular, triggered by the formation of a mechanical coupling between the token and the tradesman's device, use of the tradesman's device by the user can then be granted or an access right can be denied, or the manner of use can be regulated in accordance with the personalized user profile.By assigning a user-specific authorization profile to individual tradesman devices within a tradesman's equipment, even in complex systems with a large number of tradesman devices, tokens, and users, a quick and error-resistant comparison between user profiles and tradesman devices can be performed using a user-specific token, thus achieving efficient access management. At the same time, a high degree of operational reliability can be achieved, as authorization management is enabled efficiently and securely, even with a confusingly large number of tradesman devices, users, and tokens.

[0020] In the following, additional exemplary embodiments of the token, the craftsman equipment and the method are described.

[0021] According to an exemplary embodiment, the user's authorization profile can be stored in the token's storage device. This allows direct access to the user profile, particularly by the token's processor. According to this embodiment, the token itself is already individualized and personalized.

[0022] According to another exemplary embodiment, the token may comprise a communication device (e.g., comprising a transmitting and / or receiving antenna) configured to communicate via a communication network (e.g., the public internet, an intranet, or a mobile network) to obtain the authorization profile of the user identified by the identification device using the access-granting information. According to such an embodiment, the user profile is not stored directly on the token, but can be retrieved, for example, via a corresponding link from a node in the communication network with which the token can communicate.Said node can, for example, be a central control device for the tradesman's equipment, which can have access to a central storage device or a database in which, for example, a large number of authorization profiles (preferably related to tradesman's equipment) are stored centrally for a large number of tokens and for a large number of users. By providing such a central storage resource, the decentralized storage resources of the large number of tokens can be reduced or even eliminated entirely. This reduces the overall hardware complexity of the tradesman's equipment.

[0023] According to an exemplary embodiment, the identification device can comprise a user identification sensor, in particular a fingerprint sensor or a facial recognition sensor. Such a user identification sensor can be provided on the token itself, in particular on an outer sensor surface of the token. If a user wishes to use a tool (e.g., a drill) from a tool shop (e.g., a machine park), they simply place a finger on the fingerprint sensor of their token, thereby identifying themselves to the token. Based on this identification information, the token can determine the user's relevant user profile.By mechanically pairing the token with a tradesman device that the user wishes to use, a comparison can be triggered to determine whether or not the use of the tradesman device is permitted given the user profile of the user, and if so, whether the use of the tradesman device is subject to restrictions given the attributes of the user and / or the tradesman device. From the user's perspective, this complex process requires nothing more than performing user identification using the token's user identification sensor and mechanically pairing the token with the tradesman device. Otherwise, the user does not need to do anything. The process of user-specific management of access rights to tradesman devices is therefore simple and straightforward from a user perspective and error-robust from the tradesman equipment perspective.

[0024] According to an exemplary embodiment, the processor can be configured to compare a user identity determined by the identification device with the authorization profile and, based on this, to control whether the use of the tradesman's device by the user is permitted or prohibited and / or how the use is discontinued. The granting of unrestricted or restricted access rights or the denial of access rights to a tradesman's device can thus be achieved by comparing an authorization profile identified by the user's identification with a tradesman's device for which a user expresses a desire for access by mechanically coupling their token.

[0025] According to an exemplary embodiment, 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 tradesman's tool based on a user qualification and / or a physical or biological user characteristic, a user-specific permission to use for at least one defined operating mode of the tradesman's tool, and an occupational health and safety-related condition of use for the use of the tradesman's tool. A user qualification that can be reflected in a user's authorization profile is, for example, instruction in the use of a tradesman's tool (e.g., a chainsaw) and / or the presence of a required authorization to operate a tradesman's tool in a jurisdiction (e.g., a driver's license authorizing the operation of a forklift).A physical user characteristic can, for example, be a user's physical limitation that restricts the use of a tradesman's tool for medical or occupational safety reasons. A biological user characteristic can, for example, be age that restricts the use of a tradesman's tool for medical or occupational safety reasons. For example, users above or below a certain age may only be permitted to use handheld devices up to a specified weight limit, which can also be reflected in the personalized authorization profile. For occupational safety reasons, it may be mandatory to wear certain protective equipment (e.g., safety goggles, protective gowns, etc.) when using certain tradesman's tools.For example, a user may be denied use of such a tradesman's device until it has been verified that the user is wearing the prescribed protective equipment. For this purpose, a piece of protective equipment can be provided with a token that can communicate with a token mechanically linked to a tradesman's device. Only when the token on the tradesman's device is notified, through communication with the token on the protective equipment, that the required protective equipment is present can the token's processor in the tradesman's device authorize use of the tradesman's device. This can increase operational safety.

[0026] According to an exemplary embodiment, the processor can be configured to permit or prohibit, upon coupling with the tradesman device, the download of a data set, in particular a data set defining an operating sequence of the tradesman device, from a communications network based on the personalized authorization profile. If a comparison of the authorization profile of an identified user with a tradesman device for which the user expresses a desire to use by mechanically coupling their token results in the result that use is permitted in whole or in part, a download of operating information relating to this tradesman device can be initiated or permitted. The token's processor can then control the use of the tradesman device based on the downloaded operating information.

[0027] According to an exemplary embodiment, the processor can be configured to enable operation of the tradesman's device coupled to the token only if user identification performed in advance using the token has resulted in the identification of an identifying user being authorized to operate the tradesman's device. According to an exemplary embodiment, operation of the tradesman's device without coupling with the token can be prevented. Without positive verification of a user's authorization to use a specific tradesman's device, use of the tradesman's device can be deactivated. If a user presses an actuation button on a drill without or before verifying the user authorization, the token's processor prevents the drill from operating.The requirement for a user to positively confirm their authorization to use a tradesman's device increases operational safety and prevents misuse.

[0028] According to an exemplary embodiment, the token's processor can be configured to permit, disable, and / or prohibit the use of the respective tradesman's device by the user in different ways based on the personalized authorization profile when coupled with different tradesman's devices. A user's personalized authorization profile can thus be customized differently for several different tradesman's devices, i.e., it can define different usage rights, usage restrictions, and / or usage prohibitions for a user with regard to different tradesman's devices.

[0029] According to an exemplary embodiment, the token can have a detection device, in particular a camera, which is designed to detect processing information indicative of a processing task to be performed by the tradesman's device, wherein the processor is designed to execute the processing task using the detected processing information. For example, an optical detection device of the token can be used to detect which fastening element (e.g., an M8 screw) a user intends to insert into a substrate using a tradesman's device, e.g., a cordless screwdriver. The processor of the token can then adapt the operating mode of the tradesman's device to the detected information, for example, by setting a torque accordingly.It is also possible that the (e.g. optical) detection information is not provided by the token, but for example by a camera of the tradesman's device or by a camera of a user terminal (e.g. a mobile device) that a user carries with them (and can optionally also be used for user-defined control of a token).

[0030] According to an exemplary embodiment, the token can have a mechanical coupling device configured for mechanical coupling with various tradesman tools. The token is configured to control said tradesman tool by means of the processor upon mechanical coupling of the mechanical coupling device to a tradesman tool. Within the scope of the present application, a "mechanical coupling device" can be understood in particular as a physical structure or form factor of the token, which can be coupled, for example, in a form-fitting and / or friction-fitting manner to a corresponding physical structure of a tradesman tool, thereby forming a particularly temporary and well-defined mechanical connection between the token and the tradesman tool.For example, the token can be inserted into a correspondingly shaped receiving opening in the tradesman's device in order to mechanically couple the token and the tradesman's device. The mechanical coupling device can be designed to simultaneously establish a communicable coupling between the token and the handheld device by simply forming a mechanical coupling with a tradesman's device. The formation of a mechanical coupling between a tradesman's device and a token can be interpreted by the token's processor as a user's desire to operate the tradesman's device and can trigger a comparison of a personalized user profile of the user with the mechanically coupled tradesman's device. This trigger logic allows authorization verification to be carried out quickly and with a high level of user convenience, and the use of the tradesman's device can be authorized by the user if the personalized user profile permits it.

[0031] According to an exemplary embodiment, the mechanical coupling device can be configured to removably couple the token to the tradesman's device. In this way, a user who wishes to use a tradesman's device can mechanically couple a token assigned to them to the tradesman's device and, after use, remove the token from the tradesman's device in order to subsequently use the token in combination with another tradesman's device. The tradesman's device can be configured to permit control of the tradesman's device by the token or use of the tradesman's device only while a mechanical coupling to a token exists.

[0032] According to an exemplary embodiment, the mechanical coupling device can have an electromechanical interface, in particular a universal electromechanical interface for different tradesmen's devices. An electromechanical interface can be understood here as meaning that the formation of a mechanical connection between the mechanical coupling device of the token and a corresponding mechanical receiving or connecting device of the tradesmen's device simultaneously leads to the formation of an electrical coupling between the token and the tradesmen's device. Then, for example, a positive coupling of the token and the tradesmen's device can also enable the transmission of an electrical control signal from an electrical contact of the token to an electrical contact of the tradesmen's device. Such tradesmen's equipment is particularly error-resistant in operation.

[0033] According to an exemplary embodiment, the token can be configured to establish a communication connection, in particular a contactless or contact-based communication connection, with the tradesman's device upon mechanical coupling of the mechanical coupling device to the tradesman's device. Referring to the previously described embodiment concerning an electromechanical coupling between the token and the tradesman's device, contact-based electrical communication between the token and the tradesman's device can preferably only be enabled upon formation of the mechanical connection. This allows a user to retain control through an intuitive connection process. Alternatively, a contactless communication connection between the token and the tradesman's device can only be established upon formation of a mechanical coupling between the token and the tradesman's device.For example, only by inserting the token into the tradesman's device can a wireless transponder (e.g., an RFID tag) of the token be brought within readability distance of a transponder reader (e.g., an RFID reader) of the tradesman's device. 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 tradesman's device.

[0034] According to an exemplary embodiment, the tradesman device can have a storage device for storing the authorization profile. In particular, the storage device of the tradesman device can be communicatively coupled to the token, in particular to store the authorization profile in the storage device using the token and / or download it from the storage device. In this way, an authorization profile can also be stored in the tradesman device, to which a token can gain access (for example, triggered by a mechanical coupling of the token to the tradesman device). This allows the hardware resources of the token to be reduced, since the token can also download a data set with a user's personalized authorization profile from a tradesman device.

[0035] According to an exemplary embodiment, the craftsman's device can be designed as a motorized or electric hand-held device from 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, and a hammer drill.

[0036] According to an exemplary embodiment, the tradesman's equipment can comprise a plurality of tradesman's devices, at least some of which are configured to interact with the token. Preferably, a tradesman's equipment can contain a plurality (in particular at least ten, further in particular at least one hundred) of tradesman's devices and a plurality of tokens (in particular at least ten, further in particular at least one hundred) for managing usage rights of a plurality of users (in particular at least ten, further in particular at least one hundred). The described system is easily scalable and can be used in a fault-robust manner even with the most complex machine parks.

[0037] According to an exemplary embodiment, the tradesman equipment may identify at least two different elements from a group consisting of an electric or motor-driven handheld device (e.g., a drill), a tool (e.g., a drill or a screwdriver) or a tool set (e.g., a drill bit set in a drill bit box), a storage system (e.g., a case or a toolbox), a consumable (e.g., a bolt anchor or a box of dowels), and a vehicle (e.g., a passenger car or a forklift). According to a preferred embodiment, multiple handheld devices, multiple tools, multiple storage systems, multiple consumables, and multiple vehicles may be managed as tradesman equipment.A configuration with a multitude of tokens and a multitude of tradesman devices of different types, in which each token can be mechanically coupled to any tradesman device and thus functionally connected, creates a complex and infinitely scalable system that enables efficient and reliable management of even a large number of tradesman devices. By allowing communication between a respective token and a mechanically coupled tradesman device and / or communication between different tokens and / or at least one other node in an associated communication network, even a huge, diversified, and spatially decentralized system of tradesman devices (for example, a company's machine park or tradesman equipment) can be managed in a fault-robust, reliable, and misuse-proof manner.

[0038] According to an exemplary embodiment, the processor can be configured to permit the use of the tradesman's device by the user only after verification that the user is wearing protective equipment required for the use of the tradesman's device. In particular, the processor can be configured to detect the protective equipment using sensors, in particular by means of a camera on the token and / or the tradesman's device and / or by communicating with a communication device or a token of the protective equipment. Without positive proof—in particular, proof detected by sensors or verified by a communication message—that the user is wearing protective equipment required for the operation of a tradesman's device, the operation of an associated tradesman's device can be deactivated.For example, a camera on the token, the tradesman's device, or a user device can be used to detect whether the user is wearing the safety equipment in question. It is also possible for the safety equipment to be equipped with another token that can communicate wirelessly with the token on a tradesman's device, thereby verifying the presence of the safety equipment via a communication message.

[0039] In the following, exemplary embodiments of the present invention are described in detail with reference to the following figures. Figure 1 shows a craftsman's equipment with craftsman's devices and tokens according to an exemplary embodiment of the invention, which are coupled in a communication network with additional communicable nodes. Figure 2shows 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 devices and a token according to an exemplary embodiment of the invention, which are coupled in a communication network.

[0040] The same or similar components in different figures are provided with the same reference numerals.

[0041] Before exemplary embodiments of the invention are described with reference to the figures, some general aspects of embodiments of the invention will be explained.

[0042] According to an exemplary embodiment, a token may be used for use with a craftsman's device (for example, a machine tool).

[0043] The token can, for example, be provided with a combined electrical and mechanical structure. More precisely, different tokens of a token arrangement can have a common electrical and / or mechanical basic structure, but can also differ with regard to a variable electrical and / or mechanical additional structure. As fixed constituents, different tokens of a token arrangement can have a processor (which can, for example, also perform post-processing and / or data compression tasks), a communication device, and a cryptography unit (in particular a decrypter). A variable portion of different tokens of a token arrangement can, for example, have differences with regard to at least one transmitting / receiving unit, at least one antenna, and / or at least one sensor.A respective token can be embodied as an object that can have a packaging component, one or more slots, compatibility with a battery, and / or a conductor adapter. It is also possible for a token to be supplied with electrical power externally. According to an exemplary embodiment, a token system can execute (in particular indirect) control of a tradesman's device using an authorization concept, in particular using a personalized authorization concept.

[0044] Tokens in a token arrangement can have different levels of functionality and can therefore be assigned to different generations. For example, a token with a first level of functionality can be equipped with a processor or communication as a BLE-enabled token with limited sensors (e.g., just a temperature and a vibration sensor). Such a token can, for example, be used to download data sheets from a central node in a communications network. The execution of a processing task using a tradesman's device assigned to a token can, for example, be made dependent on the current ambient temperature. For example, the setting of a chemical anchor can only be permitted if a minimum processing temperature is ensured. A second generation token can, for example, be equipped with a processor or communicationCommunicatively, it can be designed as an ultra-wideband token that can also be equipped with a gyro sensor. For example, such a gyro sensor can detect when a handheld device (e.g., a drill) falls to the ground and can then automatically switch the device off. A third-generation token can, in turn, be additionally equipped with NB IoT (Narrow Band Internet of Things) functionality and a GPS sensor. A third-generation token can thus be capable of determining the location of the token and a mechanically linked tradesman's device and only granting authorization to operate the tradesman's device if the determined location is permitted for the intended operation of the tradesman's device. For example, the commissioning of an excavator can only be authorized if the excavator is located on a specific construction site. This provides protection against misuse.

[0045] According to an exemplary embodiment of the invention, a token forms a basic unit of a system for the controlled operation of tradesman devices. Such a token can have a fixed component (in particular with a microcontroller, decrypter), which can be contained in each token of a token arrangement. Furthermore, each token of a token arrangement can enable an electromechanical connection to tradesman devices (in particular, provide one or more electrical contacts for electrically coupling with a tradesman device). In addition, tokens of a token arrangement can have a variable component, which can be different for different tokens. Such a variable component can enable a token to be equipped with one or more sensors (e.g., fingerprint sensor, gyroscope, GPS sensor, UWB sensor, temperature sensor), at least one radio chip (e.g., configured according to Bluetooth Low Energy, Bluetooth, NB-IoT, LTE Cat.M, 5G, NFC) and / or at least one antenna (e.g., configured according to 2.5 GPS, BLE, UWB, NB-IoT). Optionally, a token can be equipped with its own power supply, for example, a battery.

[0046] One or more tokens with the described properties can form part of a system of tradesman's equipment, which can also include tradesman's tools (such as cordless drills, tools, cases, shelves, etc.). Software components (such as IoT cloud software, an app, etc.) can also be part of such a system.

[0047] According to an exemplary embodiment of the invention, a token preferably has a mechanical coupling device, which can be embodied as an electromechanical coupling. This mechanical coupling device can be plugged onto or into electromechanical couplings of tradesmen's devices (such as handheld devices, tools, cases, shelves, etc.). It is also possible to attach a mechanical coupling device of a token to or in a housing provided for this purpose (e.g., a tracker) or to or in other devices (e.g., a device for filling empty spray cans, etc.).

[0048] During operation, a token can communicate with the tradesman's device or other device into which the token is inserted. In this way, a token can determine which object the token is inserted into. A uniform bus for all objects is therefore advantageous. This ensures that in a complex system of tradesman's equipment (for example, a company's machine park or tradesman's equipment), each token can be mechanically and communicatively connected (in particular, a control connection) to each tradesman's device. In more general terms, all tradesman's devices in a tradesman's equipment system can be equipped with a mechanically identical connecting device, all of which can be optionally coupled with the same token. In other words, the token can be plugged into all of these objects as a module.

[0049] According to an exemplary embodiment, a token can transmit documents and / or control signals to the power tool (e.g., a cordless drill) into which the token has been inserted. Alternatively or additionally, it is possible for a token to download documents relating to an additional device connected to a handheld device (e.g., a tool, an adapter, etc.). A token can also download documents relating to a workpiece to be processed with a power tool (e.g., a concrete anchor) and thus control the power tool accordingly (e.g., controlling a speed for drilling and / or driving a concrete anchor).

[0050] Preferably, a token can download authorizations for a tradesman's device (e.g., a handheld device, tool, case, shelf, etc.) so that the tradesman's device can only be operated in a specific spatial area (e.g., drills only on a construction site). For this purpose, a GPS sensor can be implemented in the token or associated tradesman's device, providing current location information.

[0051] In particular, according to an exemplary embodiment of the invention, a token can download authorizations for a tradesman's device (e.g., a handheld device, tool, case, shelf, etc.) so that the tradesman's device can only be used or operated by specific persons (e.g., only trained personnel). In particular, the token can download authorizations for the tradesman's device so that the tradesman's device can only be operated with specific personal protective equipment.

[0052] A token can control a mechanically linked tool, for example, turning a vacuum cleaner on or off. For example, when turning on a drill, the token can also trigger the activation of a dust extractor, so a user doesn't need another hand to turn on the associated vacuum cleaner.

[0053] According to one embodiment, a token may be equipped with an optical sensor (e.g., a camera or a laser scanner) to identify a product or body (e.g., a wall or a screw) that is processed with a craftsman's tool.

[0054] It is also possible for the token to download product information about the product from a node of a communication network that is connected to it in a communicative manner. The token or a mechanically connected tradesman's tool then knows how to process the product, for example, what torque is required.

[0055] According to an exemplary embodiment of the invention, a user-specific token, for example, can be verified for providing, locating, and / or processing a personalized authorization profile of the user with regard to the use of tradesman devices referenced in the personalized authorization profile. This authorization profile can regulate access or usage rights and their limits based on the user's personal or physical attributes, qualifications, and / or limitations. After (particularly sensory) identification of a user, their personalized authorization profile can be identified and analyzed to determine whether it permits the use of a specific tradesman device. This tradesman device can be selected by the user by establishing a mechanical link between their token and this tradesman device.A ban on using a tradesman's tool can advantageously only be lifted once the identified user has been verified, based on the personalized authorization profile, to be authorized to use the tool. It is also possible to permit only limited or conditional use of such a tool.

[0056] According to an exemplary embodiment of the invention, craftsman's equipment, i.e., components of a craftsman's work environment, can be efficiently managed with regard to a user's access rights to these components. Said components can in particular comprise handheld devices, tools, cases, shelves, and the like. Each of these components can be equipped with an electromechanical interface for a token, such that a respective token can be removably inserted into the electromechanical interface of each component. Each token preferably has an electromechanical interface for connection to a respective electromechanical interface of a respective one of the components. Advantageously, a respective token can communicate with an associated component so that the token knows which component it is inserted into and which component it is therefore currently assigned to.The token can control the component assigned to it by forming a mechanical coupling, in particular activating and deactivating it. In this context, it is possible for the token to contain information regarding authorizations for a respective component or to load this information via a communications network (e.g., from the internet or an intranet). Components can advantageously have an identification interface for identifying a user of the component. A respective token can also download documents via a communications network (e.g., from the internet or an intranet) for controlling and the like the component assigned to the token, receive them from an app, or receive them from a transponder or tag. The token can advantageously have a wireless connection to the communications network (e.g., the internet or an intranet) (e.g., a WLAN antenna, a SIM card, etc.).

[0057] A respective token can have a communicative connection to a respective tradesman's device (e.g., a handheld device, a tool, a case, a shelf, etc.), which can be implemented in particular via a contactless radio connection or a contact-based electrical connection. Advantageously, a token can be plugged into a respective tradesman's device in a modular, interchangeable manner. For this purpose, a token can advantageously have an electromechanical interface, which can be the same for all tokens of a tradesman's equipment.

[0058] According to an advantageous embodiment, a token can download documents from a communicatively coupled node, which can be used, for example, as a basis for controlling a tradesman's device mechanically coupled to the token. A token according to an exemplary embodiment of the invention can load authorizations in a user system for tradesman's devices and the like from a cloud and lock or appropriately control tradesman's devices and the like. It is also possible for the token to store authorizations for a tradesman's device on the tradesman's device itself (for example, using a fingerprint sensor). A user can store fingerprints directly on a module.

[0059] According to an exemplary embodiment of the invention, the token can have different levels of functionality in different variants. For example, a first-generation token can only support Bluetooth communication and, in terms of its sensors, only have a temperature sensor and a vibration sensor. A second-generation token can, in addition to a first-generation token, also support WLAN communication and, in terms of its sensors, additionally have a gyroscope. A third-generation token can, in addition to a second-generation token, support communication using a SIM card and, in terms of its sensors, have a GPS sensor. A fourth-generation token can, in addition to a third-generation token, have a fingerprint sensor and, as additional equipment, an app for connecting to devices, a cell phone, etc.have.

[0060] According to one embodiment of the invention, a token can be in communication with an app in order to, for example, recognize a tool (e.g., a drill) and a workpiece (e.g., a concrete anchor) and to control and process them accordingly.

[0061] It is possible to implement an identification device or identification interface via an electronic chip in clothing (for example in a glove, in a shoe and / or in a helmet), via an electronic chip in the body, via one or more separate tags or keys, via a mobile phone and / or via an app.

[0062] A token can advantageously enable theft protection, since according to an exemplary embodiment of the invention, the activation of a tradesman's device can be made conditional upon the identification of a user and verification of the identified user's authorization based on a personalized authorization profile. For example, a token can be equipped with a fingerprint sensor, a facial recognition sensor, or the like to identify a user. It is then possible to enable the operation of a tradesman's device (e.g., a machine) only with appropriately authorized tokens.

[0063] A personalized authorization profile can be stored on a token. Alternatively or additionally, a personalized authorization profile can be stored in a cloud. In this case, a token can download a personalized authorization profile relating to a user and a tradesman's device to be put into operation (for example, tools and / or handheld devices). The token can save a personalized authorization profile after each download so that it is available offline. Alternatively or additionally, a personalized authorization profile can be stored in a tradesman's device (in particular, in a machine or battery). A token can then identify itself on a tradesman's device (in particular, a machine and / or battery).

[0064] According to exemplary embodiments of the invention, it is advantageous if an authorization profile also includes user-specific data. For example, if a machine is too heavy for a particular user, this machine can be locked for that user.

[0065] Advantageously, according to an exemplary embodiment of the invention, a token can be plugged into a tracker. In this way, the current position of a respective token can be determined, for example, if a token assigned to a tracker can communicate with mobile devices in its vicinity and the mobile devices transmit corresponding information, for example to a central control device. In this way, location tracking of each token and therefore of each assigned tradesman's device is possible. A tracker can be attached to a tradesman's device (for example, a handheld device or any other machine), for example by gluing, a magnetic connection, or by mechanical locking. In particular, a token can be plugged into a tracker.A tracker may also be equipped with a power supply device (e.g. a battery) and one or more antennas (in particular for communication according to RFID and / or WLAN and / or Bluetooth).

[0066] 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 devices 102 and tokens 100 according to an exemplary embodiment of the invention, which are coupled in a communication network 120.

[0067] More specifically, the craftsman's equipment 104 comprises a plurality of tokens 100, which may, for example, all be shaped and dimensioned in the same way. Figure 1 only two such tokens 100 are shown, but 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).

[0068] In addition, the craftsman equipment 104 includes a plurality of craftsman tools 102. In Figure 1 Only two such tradesman tools 102 are shown, however, a much larger number of tradesman tools 102 is possible in a tradesman's equipment 104 (for example, at least ten, in particular at least one hundred). Some or all of the tradesman 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 of the tokens 100 selected by the user. A positive connection can be formed between each mechanical coupling device 110 of each token 100 and each mechanical receiving device 152 of each tradesman tool 102 by plugging them together.

[0069] When a mechanical connection is established between a token 100 and a selected tradesman device 102 by inserting the mechanical coupling device 110 of the token 100 into the receptacle 152 of the selected tradesman device 102, an operative or communication connection is simultaneously established between the token 100 and the tradesman device 102. More specifically, in the illustrated embodiment, an electrical connection is established between one or more electrical contacts 156 on an outer side of each token 100 and one or more electrical mating contacts 136 on an inner side of each receptacle 152 of each tradesman device 102.The formation of a positive connection between a respective token 100 and a respective receiving device 152 of a tradesman's device 102 thus leads to the formation of an electrical contact and thus an electrically conductive connection between the token 100 and this tradesman's device 102. This electrical connection also forms an electrical communication connection between the token 100 and the tradesman's device 102, which in particular enables the transmission of electrical signals (for example, control signals). As an alternative to this contact-based electrical coupling, a wireless orA contactless communication connection between a token 100 and a tradesman's device 102 can be formed by inserting the token 100 into the receiving device 152, bringing a transponder (for example an RFID tag, not shown) of the token 100 into a readability distance of a transponder reader (for example an RFID reader, not shown) of the tradesman's device 102 (not shown).

[0070] A token 100 is advantageously configured to control the tradesman's device 102 when it has been brought into communication with the tradesman's device 102 by insertion into the receiving device 152 of the tradesman's device 102. Operation of the tradesman's device 102 in a state without coupling with the token 100 can be prevented. In other words, its use can only be enabled upon successful coupling of the token 100 and the tradesman's device 103.

[0071] By allowing each token 100 to be selectively coupled to each mechanical receiving device 152 of a selected tradesman device 102, a flexibly combinable, modular system for operating, controlling and / or managing tradesman devices 102 in a complex tradesman equipment 100 is created.

[0072] In Figure 1the tradesman's tools 102 are only partially and only schematically shown. For example, a first part of the tradesman's tools 102 can be designed as electric or motor-driven handheld devices, for example as electric drills, electric cordless screwdrivers, etc. Tradesman's tools 102 designed as electric or motor-driven handheld devices can, for example, have a functional device 134 which performs the actual function of the respective handheld device and can be driven by means of an electric or motor drive. In a tradesman's tool 102 designed as a drill, the functional device 134 can, for example, be a drill chuck (in particular with a drill bit). In a tradesman's tool 102 designed as a cordless screwdriver, the functional device 134 can, for example, be a bit holder (in particular with a bit).Furthermore, a handset can have a power supply device 142, for example, a removable and rechargeable battery pack. Such a power supply device 142 can supply the functional device 134 with electrical drive energy during operation. Alternatively or additionally, the power supply device 142 can also supply a token 100 with electrical energy when the token is received in the receiving device 152. A handset can also have a control device 138, which can be configured to control the handset (for example, when a handset is not coupled to a token 100) and / or to interact with a processor 106 of a coupled token 100.

[0073] A second part (not shown) of the tools 102 can be designed as (particularly non-electrical or non-motorized) tools or tool sets, for example as a screwdriver, drill or drill box, bit or bit box, etc.

[0074] A third part (not shown) of the tradesman's equipment 102 can be designed as storage systems for storing hand tools, tools, and consumables. Examples of such storage systems include boxes, cases, drawers, and / or shelves for accommodating or storing hand tools, tools, and / or consumables.

[0075] A fourth part (not shown) of the tools 102 can be designed as consumables, for example boxes with screws or dowels, or as bolt anchors.

[0076] A fifth part (not shown) of the tradesman's equipment 102 can be designed as motor-driven vehicles, for example, cars or trucks, forklifts, and / or excavators, as used to perform tradesman's tasks. Non-motorized vehicles powered by human power, such as a push-along tool cart, can also be used.

[0077] A sixth part (not shown) of the craftsman's tools 102 can be designed as other aids and equipment of the craftsman's equipment 104, for example as ladders, scaffolding, etc.

[0078] A part or each of the described craftsman devices 102 can be temporarily or permanently equipped with a token 100.

[0079] Advantageously, the tradesman devices 102 are configured for coupling with the tokens 100 in such a way that the use of a tradesman device 102 coupled with a token 100 by a user can be permitted, configured, and / or prohibited based on a personalized authorization profile. More specifically, a user of a token 100 can be assigned a user profile that can contain information regarding the user's ability and authorization to use certain tradesman devices 102, but can also define usage restrictions and / or usage prohibitions with regard to certain tradesman devices 102.Such a user profile can be stored in a storage device 128 of a token 100, in a storage device 140 of a tradesman's device 102 and / or in a database 132 of a node communicatively coupled to the token 100 via a communication network 120 (in the illustrated embodiment, a central control device 124, alternatively another node).

[0080] In the following, the structure of the token 100 is described in more detail as an example, which is Figure 1is shown in detail. Said token 100 serves, for example, for the user-related control of a selectable one of the tradesman devices 102 of the tradesman equipment 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 be designed, for example, 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 the control-technical interaction with different tradesman devices 102 of the tradesman equipment 104, and in particular interacts functionally with a selected tradesman device 102, into whose receiving device 152 the token 100 is inserted.

[0081] Furthermore, the token 100 contains a cryptography unit 108 that supports cryptographic communication of the token 100. More specifically, the cryptography unit 108 can be used to encrypt communication between the token 100 and a communication partner device in the communication network 120. For example, such encrypted communication supported by the cryptography unit 108 can take place between the token 100, on the one hand, and a central control device 124, a user terminal 122, and / or a reordering device 126, on the other hand. Encrypted communication increases data security during communication via the communication network 120.Optionally, it is also possible to use the cryptography unit 108 to carry out encrypted communication between the token 100 and a tradesman's device 102 mechanically coupled to it, for example when transmitting control signals from the token 100 to a tradesman's device 102 designed as a handheld device. This leads to secure control of a respective tradesman's device 102, since a hacker attack or unauthorized control from outside can thereby be prevented.

[0082] As already mentioned, the token 100 has the mechanical coupling device 110, which is designed for preferably positive mechanical coupling to a receiving device 152 of a respective one of different tradesman's tools 102 of the tradesman's equipment 104. The mechanical coupling device 110 of the token 100 is defined by its outer shape, which is designed inversely to the inner shape of a receiving device 152 of a respective tradesman's tool 102.

[0083] The token 100 can advantageously be configured to control the operation of said tradesman's device 102 by means of the processor 106 (and optionally the cryptography unit 108 using cryptographic communication) upon mechanical coupling of the mechanical coupling device 110 to a receiving device 152 of a selected tradesman's device 102. More specifically, the processor 106 of the token 100 can control the tradesman's device 102 and, in particular, its functional device 134 such that the desired processing task is performed by the tradesman's device 102 as intended. For example, the processor 106 of the token 100 can specify the torque applied by a drill bit of a tradesman's device 102 configured as a drilling machine to a substrate in which a borehole is to be drilled.

[0084] The token 100 can advantageously be designed for user-related control of the tradesman's device 102, in particular based on a personalized authorization profile of the user. For this purpose, the token 100 can be provided with an identification device 170 designed to identify a user of the token 100. The identification device 170 is formed by a sensor 112, designed, for example, as a fingerprint sensor, and the part of the processor 106 that identifies the user from sensor data determined by the sensor 112, for example, by a pattern comparison with reference data. More precisely, the sensor 112 is designed, for example, as a fingerprint sensor, onto which a user places a finger for identification. The sensor 112 can therefore advantageously be attached to a surface region of the token 100.The sensor 112 can then determine whether the data captured by the sensor 112 indicates that the user is an authorized or authorized user, or which user that user 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).

[0085] The aforementioned storage device 128 of the token 100 can store information indicative of a personalized authorization profile of the user with respect to the tradesman device 102 or granting access thereto. More specifically, a data set representing or mapping an authorization profile of a user (or multiple authorization profiles of multiple users) can be stored in the storage device 128 of the token 100. However, it is also possible for the authorization profile of one or more users to be stored in an entity located remotely with respect to the token 100, for example, in a central database 132 of a central control device 124, to which the token 100 can be communicatively coupled 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 for accessing the remotely stored authorization profile.

[0086] The processor 106 can be configured to control the operation of the tradesman device 102 coupled to the token 100 in accordance with the user authorization profile of the user of the token 100. In particular, the processor 106 can be configured to only enable the operation of the tradesman device 102 coupled to the token 100 if a user identification performed in advance using the token 100 has resulted in the result that an identifying user is authorized to operate the tradesman device 102. Advantageously, the processor 106 of the token 100 can thus be configured to permit, suspend, and / or prevent use of the tradesman device 102 by the user based on the personalized authorization profile when coupled to the tradesman device 102.For example, a processing task desired by a user using a tradesman's device 102 may only be permitted for certain users, for example, if the user has received specific instruction or has obtained special qualifications (e.g., a driver's license) to use the tradesman's device 102. If the user's authorization profile does not fulfill such a condition, the use of the tradesman's device 102 can be prevented by the processor 106 of the token 100. If, however, the user's authorization profile does fulfill such a condition, the use of the tradesman's device 102 can be permitted by the processor 106 of the token 100. If, due to an authorization profile, certain processing tasks are only permitted for a user to a limited extent, the use of the tradesman's device 102 by the user is only permitted if an associated condition is met.For example, the use of a tradesman's tool 102 by a user may only be permitted if the user is wearing protective equipment (e.g., safety goggles). If such protective equipment is also identified by a token 100, the processor 106 may search for a communicatively coupled token 100 indicating protective equipment, and may only permit the user to perform the desired processing task once the presence of protective equipment has been detected by the presence of such a token 100.

[0087] As in Figure 1As shown, the tradesman's equipment 104 may include a token assembly 130 comprised of a plurality of tokens 100, with different tokens 100 having different degrees of functionality. For example, the tokens 100 of a tradesman's equipment 104 may be divided into first, second, and third generation tokens 100. Each token 100 of any generation may fulfill the basic function of a token 100, as described above. Tokens 100 of higher generations may also have additional functions and / or additional convenience, but may also support the basic function of a token 100 of the lowest generation. Tokens 100 of all generations may have the same shape and may be used with any tradesman's equipment 102 of the tradesman's equipment 104. In other words, the token assembly 130 is compatible with different generations of tokens 100.The tradesman devices 102 do not require any adaptation with regard to their interaction with a token 100 of a respective generation, except that a receiving device 152 is provided for mechanically receiving an associated token 100.

[0088] Each of the inserted tokens 100 can, for example, be designed as a plug-in element for insertion into a receiving opening of a tradesman's tool 102. For example, each token 100 can be designed as a circular disk with a diameter in a range of 2 cm to 4 cm and is therefore easy to handle by a user and can be inserted into a tradesman's tool 102 in a space-saving manner. Other shapes of a token 100 are possible, see, for example, Figure 3Furthermore, the mechanical coupling device 110 of each token 100 is configured to removably couple the token 100 to the tradesman's device 102. Thus, a user can use a token 100 (e.g., one assigned to him) consecutively in combination with different tradesman's devices 102, wherein the selection of an addressed tradesman's device 102 can be performed by simply mechanically inserting the mechanical coupling device 110 of the token 100 into an associated receiving device 152 of a target tradesman's device 102. Thus, the mechanical coupling device 110 of a token 100 serves as a universal electromechanical interface for different tradesman's devices 102.

[0089] As already mentioned, the token 100 can have one or more sensors 112, including the user identification sensor described above. Alternatively or additionally, it is possible to equip the token 100 with, for example, a gyro sensor, a location sensor, and / or a temperature sensor. A gyro sensor can detect, for example, when a tradesman's tool 102 with the token 100 housed therein falls and is consequently subjected to a shock. In this case, the tradesman's tool 102 can be switched off as a precaution to prevent injury to a user and damage. A location sensor (for example, a GPS sensor) of the token 100 allows the current position of the token 100 and the tradesman's tool 102 to be detected.The use of a tradesman's device 102 can be restricted (e.g., in a user profile) to a specific spatial area (e.g., a specific construction site), for example, to prevent misuse. If a location sensor detects that a tradesman's device 102 including a token 100 is located in a location not authorized for use, the processor 106 of the token 100 can switch off or deactivate the tradesman's device 102 to prevent misuse. A temperature sensor of the token 100 can detect the ambient temperature. If a processing task (e.g., setting a chemical anchor) is only permitted under certain temperature conditions, operation of the tradesman's device 102 can be prevented for safety reasons if a temperature condition is not met based on the detected temperature sensor data.

[0090] Optionally, the token 100 has a power supply device 116, for example, a replaceable battery or a rechargeable battery. The token 100 can then be operated autonomously. Alternatively or additionally, the token 100 can be supplied with electrical energy by a power supply device 142 of a tradesman's device 102 when the token 100 is received in the receiving device 152.

[0091] Figure 1further shows that the token 100 can have a communication antenna 114, for example, a WLAN antenna. It is also possible and advantageous for reasons of diversity if the token 100 has multiple communication antennas 114, which, for example, support different communication protocols. For example, a communication antenna 114 can be implemented in the form of a planar coil, which is preferably arranged in a surface region of the token 100. A communication antenna 114 can be designed as a transmitting / receiving antenna. It is also possible to provide a transmitting antenna and a separate receiving antenna, or just one of these antennas.

[0092] In addition, the Figure 1The token 100 shown has 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 cryptography unit 108. The communication device 118 serves to communicate the token 100 with one or more communication nodes via the communication network 120. This can be, for example, the public Internet, an intranet, or a mobile network.

[0093] For example, the token 100 can communicate via the communication network 120—or directly—with another token 100 of the tradesman's equipment 104. This can be done, for example, for the purpose of detecting the presence of protective equipment equipped with a token 100 (which, for occupational safety reasons, can be made a condition for authorization to use a tradesman's equipment 102).

[0094] 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 terminal 122 via the communication network 120. In the illustrated embodiment, the user terminal 122 is a mobile radio device with a user interface with which a user can control and / or monitor the communicatively coupled token 100 and / or a tradesman device 102 coupled thereto. Using the user terminal 122, a user can also control and / or monitor the tradesman equipment 104 from a remote location. For example, a token 100 can connect to the user terminal 122, embodied here as a mobile radio device, via an app. Using the user terminal 122, data can be downloaded to the token 100, for example, a user profile of a user of the user terminal 122.Furthermore, it is possible for the token 100 to access resources of the user terminal 122 during operation, for example a processor contained therein and / or a camera of the user terminal 122.

[0095] For example, a camera contained in the user terminal 122 can be used to capture an image of product packaging, which allows a conclusion to be drawn about a consumable used for a processing task (e.g., a type of screw). This information can be transmitted from the user terminal 122 to the token 100, so that the control of a tradesman's device 102, embodied, for example, as a cordless screwdriver, for inserting a corresponding screw can be carried out accordingly by the token 100. Expressed more generally, an optical detection device, in particular a camera, can be provided, for example, on the token 100 and / or on the user terminal 122, which is designed to detect processing information indicative of a processing task to be performed by the tradesman's device 102.Advantageously, the processor 106 can be configured to execute the processing task using the detected processing information.

[0096] Alternatively or additionally, it is possible to establish a communicable link between the token 100 and a central control device 124 (for example, for controlling multiple tradesman devices 102) via the communication network 120. The central control device 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 can be, for example, a user profile requested by the token 100, an operating data record for executing a processing task with a tradesman device 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 tradesman's device 102 and / or a data set defining a user profile of a user of the token 100, from the central control device 124 or another communicatively coupled node of the communication network 120 by means of the communication device 118.

[0097] Furthermore, the communicable coupling between the token 100 and the central control device 124 makes it possible to transmit data from the token 100 to the control device 124 for storage in the database 132. Such data can be, for example, tracking data that allows tracking of a tradesman's device 102 coupled to a respective token 100. Thus, the token 100 can be configured to upload a data set, in particular a data set containing operating results and / or operating parameters of an operation of the tradesman's device 102, to the control device 124 or another communicatively coupled node of the communication network 120 via the communication device 118.

[0098] Finally, it is possible for the token 100 to be coupled via the communication network 120 to a reordering device 126 for reordering consumables for operating a tradesman's device 102. If a token 100 detects (for example, by means of a token-specific, e.g., optical, sensor 112 and / or by means of a camera image of the user terminal 122) that a remaining stock of a specific consumable (for example, a specific type of screw for insertion into a substrate using a tradesman's device 102 configured 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 initiate or trigger a reorder of this consumable.The reordering device 126 can be a computer, which in turn can be linked to supplier nodes via the communications network 120 to execute the reorder. A reorder of consumables can thus be triggered by a token 100, for example, if the token 100 and / or a tradesman's device 102 has detected, for example, by sensors, that a remaining stock of certain consumables has fallen below a predetermined threshold.

[0099] During operation of the tradesman equipment 100, for user-related control of a tradesman device 102 using a token 100, a user of the token 100 can first be identified using the sensor 112 designed as a fingerprint sensor. Subsequently, the mechanical coupling device 110 of the token 100 can be mechanically coupled to the mechanical connecting device 152 of the selected tradesman device 102. Before or after the mechanical coupling, a personalized authorization profile of the user of the token 100 can be located, for example, in one of the storage devices 128, 140. After the mechanical coupling has been completed, the tradesman device 102 can be controlled using the processor 106. In this case, use of the tradesman device 102 by the user can advantageously be permitted, prohibited, and / or discontinued based on the personalized authorization profile.In particular, the processor 106 can be configured to enable operation of the tradesman device 102 coupled to the token 100 only if a user identification performed in advance using the token 100 has resulted in the result that an identifying user is authorized to operate the tradesman device 102. In this case, the personalized authorization profile can include at least one piece of information from a group consisting of a prohibition of use for at least one defined operating mode of the tradesman device 102 related to a user qualification and / or a physical (e.g., a physical limitation) or biological (e.g., advanced age) user characteristic, a user-specific permission to use for at least one defined operating mode of the tradesman device 102, and a condition of use for the use of the tradesman device 102, for example, related to occupational health and safety.For example, the authorization profile for a specific user can contain the information that, due to their physical constitution (e.g., due to their age, height, and / or weight), the user is only authorized to use tradesman's equipment 102 up to a certain weight (e.g., up to 20 kg). Furthermore, such an authorization profile for a specific user can store which tradesman's equipment 102 the user is authorized to operate (e.g., a user may only be permitted to use a forklift if they have a forklift driver's license). Furthermore, for a specific user and / or for a specific tradesman's equipment 102, a user profile can store which protective work equipment (e.g., work coat, ear protectors, safety goggles) a user must wear in order to use a specific tradesman's equipment 102.The use of a tradesman's device 102 can be denied to a user by the token 100 until the protective work equipment on that user has been detected (e.g., by sensors). For example, the protective work equipment can also be equipped with a corresponding token 100, so that the presence of protective work equipment on the user can be verified through token-to-token communication.

[0100] The processor 106 can be configured, when coupled to the tradesman device 102, to permit or prohibit a download of a data set (e.g., a data sheet), in particular a data set defining an operating sequence of the tradesman device 102, from a communication network 120 based on the personalized authorization profile. For example, an optical sensor (e.g., a camera) of the token 100 and / or on a tradesman device 102 can scan a product package containing screws that are to be inserted into a substrate (e.g., a vertical concrete wall) in one operating mode of the tradesman device 102. In this way, it can be detected by sensors, 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 sequence) corresponding 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 device 102 by the token 100 using the downloaded data set.

[0101] Figure 2 shows a token 100 with an associated storage and recharging device according to an exemplary embodiment of the invention.

[0102] More specifically, the Figure 2The token arrangement shown comprises the token 100 and a token receptacle 150, which can be designed to receive the token 100 in a form-fitting and / or force-fitting manner. For this purpose, the token 100 can be clamped into a receiving space of the token receptacle 150, which is defined between opposing elastic legs of the token receptacle 150. In this way, a user can store the token 100 in a mechanically protected manner, for example, using a connecting element 154. By means of the connecting element 154, a user can carry the token receptacle 150, optionally together with the token 100 received therein, in a fixed manner, for example, by attaching it to a belt loop.

[0103] It is also possible to attach a token 100 with a fully or partially depleted power supply device 116 (e.g., a rechargeable battery) to the token receptacle 150, thereby triggering recharging of the power supply device 116. For this purpose, electrical energy can be transferred (e.g., through electrical contact or inductively) from a charging device 160 of the token receptacle 150 to the power supply device 116 of the token 100.

[0104] Figure 3 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 inversely shaped recess inside a craftsman's device 102.

[0105] Figure 4 shows components of a craftsman's equipment 104 according to another exemplary embodiment of the invention.

[0106] The craftsman equipment 104 according to Figure 4 contains, for example, three craftsman tools 102 and, for example, three tokens 100.

[0107] The three craftsman tools 102 according to Figure 4 are designed as a drill (top), sensor module (center), and battery pack (bottom), and are interconnectable. During operation, the battery pack supplies the drill with electrical energy, while the sensor module detects the drill's operating data (and uses this, for example, as the basis for a control system). Bidirectional signal coupling (i.e., in the transmitting and receiving directions) is enabled between the drill and the sensor module, see the two arrows. Similarly, bidirectional signal coupling is enabled between the sensor module and the battery pack.

[0108] A bidirectional signal coupling is also possible between each of the tradesman devices 102 and a respective one of the tokens 100. The configuration according to Figure 4 shows that all components 102, 100 can communicate with each other on an equal basis. The communication interfaces between components 102, 100 can be implemented, for example, according to a UART (Universal Asynchronous Receiver Transmitter) protocol.

[0109] The illustrated tokens 100 may form a token array 130 of tokens 100 of varying degrees of functionality, wherein each of the tokens 100 of the token array 130 may be mechanically and functionally coupled to any of the craftsman devices 102.

[0110] Figure 5 shows a craftsman equipment 104 with craftsman devices 102 and a token 100 according to an exemplary embodiment of the invention, which are coupled in a communication network 120. Figure 5shows a modular craftsman equipment 104 in an Internet of Things (IoT) architecture.

[0111] Reference numeral 161 indicates adapters, reference numeral 162 indicates handheld devices, reference numeral 163 indicates personal protective equipment and wearables, reference numeral 164 indicates the application of third-party tradesman devices, reference numeral 165 indicates tracking elements, reference numeral 166 indicates stockpiling systems, reference numeral 167 indicates an inventory management system, and reference numeral 168 indicates an online store. All of these systems can be incorporated into the token-controlled tradesman equipment 104.

[0112] Another application example of a token according to an exemplary embodiment of the invention is described below. At a predetermined time (for example, at a predetermined time of day, such as after work), the token can transmit operating data to a target device or to a storage device (for example, to a cloud, an app stored on a portable user device, etc.). Such operating data can, for example, contain information regarding an identified user of the token and / or a tradesman's device linked to it. Furthermore, such operating data can contain the information that certain work steps were performed with said tradesman's device on a specific day (in particular with the addition of additional information such as torque, speed, and / or time).

[0113] According to another application example of another exemplary embodiment of the invention, communication can be carried out between a plurality of devices, in particular between a plurality of tradesman devices, in particular by means of a token. For example, communication can be carried out between a first tradesman device (for example, a master device) and a second tradesman device (for example, a slave device). For example, a first tradesman device (for example, a drill) can switch on a second tradesman device (for example, a vacuum cleaner) when a drilling task is being carried out. In another example, a core drill can communicate with a guide rail for guiding the core drill, for example, to transmit current location information.It is also possible for a robot to communicate with an external device, for example to align or ensure that the robot has positioned itself correctly in the room.

[0114] According to an exemplary embodiment of the invention, it is also possible to implement a token as a tracker in a tradesman's device (e.g., in a power tool, a battery case, etc.). This makes it possible to determine the location of the tradesman's device. 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.

[0115] Additionally, it should be noted that "comprising" does not exclude other elements or steps, and "a" or "an" does not exclude a plurality. Furthermore, it should be noted that features or steps described with reference to one of the above embodiments may also be used in combination with other features or steps of other embodiments described above. Reference signs in the claims are not to be considered as limitations.
