    15 20 25 30 with correct biasing force. To guarantee this, intensive communication between the screw tool and the screw control unit is necessary.
    The communication connection necessary for this communication should therefore be realized as reliably as possible.
    The invention represents an industrial and electrically driven tool for mobile use, in particular an accumulator-driven screw tool. Any other industrially used tool, whose work steps must be documented, is also conceivable (eg resistance welding machines, riveting tools and the like).
    The tool according to the invention comprises a housing with an integrated tool control unit and an integrated first radio module for the communication of the tool control within a predefined radio frequency band with a device which is remote from the tool.
    The housing comprises a further second radio module, which operates with a radio frequency range which is different from the radio frequency range of the first radio module.
    If a radio network necessary for the operation of the tool is switched off or if the tool is out of range of the radio network, it can be automatically switched to another radio network by means of the second radio module and, where applicable, operation of the first radio module decreases or if the tool is in a radio hole that is about the transmission power too critical for the transmission frequency of the first radio module, to a radio network with a longer range. The standardization of the manufacturing process carried out by means of the tool is thus guaranteed at the same time as increasing process safety.
    Preferably, the second radio module is realized in such a way that for the production of a communication connection frequencies from radio frequency ranges which are provided for terrestrial or satellite-assisted mobile radio are used, in particular according to a GSM standard and / or UMTS standard.
    An identical parameterization for equal screw drop can thus be guaranteed all over the world, even in places where sufficient radio coverage can not be guaranteed within isolated manufacturing sites. Thus, for example, the steering of a vehicle model manufactured in different locations can be mounted with the same screw system and the same tightening parameters. The only condition is that a mobile radio network is available. It can even be dispensed with a separate internet connection, as the internet can also be used via the mobile radio network. In this case, the tool should be equipped with a means that enables the indication of an IP address, by means of which the tool control unit can at least temporarily communicate via the Internet with, for example, a superior process control.
    The second radio module uses at least one of the following radio frequency bands or an intermediate range contained therein: 876-915 MHz and / or 921-960 MHz and / or 1 710-1 785 MHz and / or 1 805-1 880 MHz and / or 1 850 -1 910 MHz, 1 930-1 990 MHz, to guarantee connection by GSM (GSM 800 / 850/900/1800 or 1900 standard supported).
    Alternatively or in addition, the second radio module utilizes at least the following radio frequency band or intermediate ranges contained therein: 1,900-2170 MHz for UMTS compatibility. Of course, radio modules can also be provided that use planned radio areas for the ground-based and / or satellite-supported mobile telephony for the future.
    Preferably, a first means is provided, by means of which the tool control identifies which radio connection is used by the device. In addition, a second means is provided by which the tool control unit can automatically activate one of the two radio modules. In addition, for example, the transmission power of the radio network used can be monitored permanently, whereby if a predefined transmission level is switched from the first to the second radio module or whereby the second radio module is also activated and an alternative or an additional connection is built up. to the higher process control unit by means of the second radio module. The process control unit can then communicate with the tool by means of both or one of the two radio modules.
    At the tool, means are preferably provided which guarantee that at least one of the radio modules can be easily replaced without the tool housing having to be opened. The housing may for this purpose comprise a recess with a contact connection for both or one of the two radio modules.
    In addition, a tool is provided with the tool which enables a manual switching between the two radio modules. This means enables the user to consciously switch, for example, from a WLAN connection to a UMTS connection, if it is already previously known that only one UMTS network is available at the place of use of the tool. A symbol that can be displayed on a display covered by the tool can alert the user to the various radio networks available.
    The invention further comprises a device for mobile use, comprising an integrated radio module. The radio module is realized in such a way that frequencies can be used from a radio frequency band which is intended for terrestrial or for satellite-assisted mobile radio. The device comprises means for configuring a tool, which means are realized in such a way that a data exchange with a tool control unit covered by the tool can be realized using a corresponding radio module which is also covered by the tool. As a device, for example, mobile telephones can be used, which enable user-specific program modules to be run on the operating system used by the mobile telephone or on the hardware used by the mobile telephone. SMS or EMAIL services can also be used for communication.
    The invention thus provides a complete system for carrying out automated industrial processes, in particular screw processes. The system according to the invention comprises a device and a tool and thus combines the advantages already described before.
    The invention also defines a method for operating a tool with an integrated tool control unit and with two independently operating integrated radio modules by means of a device which is far away from the tool and also has an integrated radio module. The radio module of the device is compatible with at least one radio module of the tool, which uses a predefined radio frequency band within a radio frequency range provided for terrestrial or satellite supported mobile radio.
    The device or tool establishes a connection to the tool while using the GSM service GPRS or while using others is used at similar By means of the tool controller, data is exchanged. The device can request data and transmit mobile radio standards as services. data. The data requested by the device is stored on a data memory covered by the device and is thus documented. This may, for example, involve screw-requiring screw processes. if the tool is an industrial screwdriver.
    The data stored on the data memory can be changed by a user by means of an input device covered by the device, for example in the case of parameters for the tool control unit or parameters for configuring the tool (IP address, GSM data server, WPA key, GSM data server ). The tool can thus be inspected and maintained remotely. Thus, between the tool and the device, all the data relating to processes performed by the tool or configuration of the tool or diagnostic data can be exchanged to eliminate disturbances in the tool.
    The first or second radio module is activated fully automatically and independently by the tool control unit, as soon as the radio network necessary for the second or the first radio module no longer provides sufficient transmission power. This guarantees a redundant communication connection between the tool control unit and the superior process control unit for data exchange.
    Fig. 1 shows roughly schematically the mode of operation of the invention.
    Fig. 2 shows a screw tool with the features according to the invention.
    None of the embodiments described below limits the invention to the said construction details. These are only possible and preferred embodiments. Deviating solution concepts using known possibilities from the state of the art can also be realized.
    Fig. 1 shows a system for carrying out automated industrial screwing processes with a device 17 and a screwing tool 13. The device 17 is a mobile phone with a user-specific program and common components such as keypad, display, etc. 171-174 for configuring the screwing tool. The program 172 is designed in such a way that it realizes a data exchange with a tool control unit covered by the tool 13 (not shown) using a corresponding radio module (not shown) which is also covered by the tool 13. The screw tool is accumulator driven, and comprises a standard data interface ( WLAN, Bluetooth By means of the screwdriver, the screwdriver can be controlled remotely using a so-called Access Point 14 which can be and the like). the standard data interface installed on the enterprise premises of a manufacturing facility. 10 15 20 25 30 The remote control takes place by means of a superior screw process control unit. Access Point 14 defines the coverage of the plant area by means of a first radio network 12. The higher screw process control unit can by means of the radio network 12 connect to the screw tool and store data specific to the screw tool on a data memory covered by the screw process control unit 15.
    The data that is wirelessly exchanged in the mobile radio network 11 is preferably data relating to: screw parameters; - screw tool configuration data; - screw tool diagnostic data; screw results By means of the modifications according to the invention, the communication between a screw tool and a screw process control unit can also take place by means of the worldwide available mobile radio network, i.e. also using a mobile telephone, which in this case serves as a temporary screw process control unit or exclusively a screw process control unit.
    Fig. 2 shows a partial section of an industrial and electrically driven screw tool.
    It comprises a housing 21 with an integrated tool control unit 22 and an integrated first WLAN / Bluetooth radio module 23 for the tool control unit communication with a device far from the tool (not shown, see Fig. 1) within predefined radio frequency ranges. The housing 21 comprises a second GSM / UMTS radio module 24 and thus uses for the production of a communication connection frequencies which are intended for terrestrial mobile radio, in particular 876-915 MHz and / or 921-960 MHz and / or 1 710-1 785 MHz and / or 1,805-1,880 MHz and / or 1,850-1,910 MHz, 1,930-1,990 MHz and / or alternatively 1,900-2,170 MHz. A radio connection monitoring 25 is provided by means of which the tool control unit 22 identifies which radio connection is currently being used by a superior screw process control unit, to include the screw tool 21 in a screw process defined by the screw process control unit.
    A radio module switching means 26 is likewise provided, by means of which the tool control unit 22 is able to fully automatically and, where appropriate, using the radio connection monitoring 25, activate one of the two radio modules 23, 24. The first or the second radio module 23, 24 can thereby be fully and independently activated of the tool controller 22, since the radio module switching means 26 covered by the tool monitors the transmission power of the radio networks that can be used and identifies as soon as the radio network necessary for the second or the first radio module 23, 24 can no longer provide sufficient transmission power. A keypad 28 is also provided, which enables a manual switching between the two radio modules 23, 24.
    At the tool 21, recesses and contact connections 27 are provided which guarantee a replaceability of at least one of the radio modules 23, 24 without the housing 21 of the tool having to be opened. For this purpose, at least one recess is provided at the housing 21, which recess comprises electrical connections which correspond to the electrical connections of at least one of the radio modules 23, 24. At least one of the radio modules 23, 24 can be located in the recess in such a way that the surface of the radio module 23 , 24 and the surface of the housing 21 forms a continuous surface. The contact points of the house must close tightly (eg be fitted with rubber strips) so that dirt or moisture cannot penetrate into the recess.
    The screw tool is configured by mobile phone. The mobile phone provides a connection to the tool via the GSM service GPRS. The current configuration of the tool is loaded on the mobile phone. The user now has the option to customize the configuration. This includes general settings such as the IP address, WPA key, telephone number of a GSM data server and the like. A configuration of the screw program is also possible. After completing the changes, the configuration can be sent back to the screwdriver.
    Calling up screw process data takes place via mobile phone. The mobile phone provides via the GSM service GPRS a connection to the tool and the current, to screw process data that is available can be automatically transmitted reads available screw results. New to the mobile phone during the existing connection. It can be set in the configuration if data after call-up by mobile phone is to be deleted from the screw tool or retained.
    For transferring screw process data to a data server, screw process data is transmitted depending on the data packet size via the GSM service GPRS or an SMS. The data server converts the obtained data (information) into the format desired by the operator of the screw tool and forwards this data to a pre-configured customer database.
    Compared to previously known solutions, the use of the tool according to the invention outside production lines, for example also in the open field, is largely possible without restriction. Already coated radio frequencies of known standards in the vicinity of production lines and their bandwidths do not have to be coated for operation of the tool. Accordingly, the operation of the tool can also not interfere with these radio frequencies or block other devices operated by radio.
