[0004] Portable work device and arrangement consisting of a portable work device and an input device

[0005] The present application relates to an electro-hydraulic work device for portable use, such as a spreader, cutter, or combination device with cutting and spreading functions, or a rescue cylinder. The aforementioned devices are primarily intended for rescue operations.

[0006] Secondly, the present invention relates to an arrangement consisting of such a working device and an input device.

[0007] Initial situation of the invention

[0008] Portable, operator-operated, motor-driven electromechanical or electrohydraulic tools or rescue equipment of the type relevant here are used in a wide variety of applications. For example, there are spreaders, cutters, or so-called combination tools—that is, devices with cutting and spreading functions as well as rescue cylinders—which are used by emergency services (firefighters), for instance, to extricate injured persons from wrecked vehicles or to free earthquake victims, or by police officers to pry open door or window gaps to gain quick access to a house or apartment. The types of tools and rescue equipment are diverse. Such devices can be subjected to extremely high mechanical demands during operation and are exposed to a wide range of environmental influences (heat, cold, humidity) depending on the location of use.The portable work tools feature an electric motor, an electric battery for power supply, and a hydraulic pump, all integrated into the tool itself. Drive units and hose connections to the work tool are therefore no longer required. Applicant: LUKAS Hydraulik GmbH.

[0011] The tools have a portable base unit that houses all components. This makes them very easy to handle and, consequently, very popular.

[0012] Past experience has shown that such portable tools are also well-suited for criminal activity, namely burglaries. This is because these devices possess considerable power. As a result, doors and windows can be opened very easily and, above all, very quickly. Consequently, there have been repeated thefts of such tools from fire stations and similar locations.

[0013] Printed state of the art

[0014] The AT 523 567 comprises a mobile rescue device that includes a deactivation mechanism for overriding the device. This deactivation is achieved via an external input device that transmits a deactivation command. This can be done manually by an operator, automatically when the mobile rescue device exceeds predefined movement limits, or when it loses its WLAN network connection.

[0015] German patent DE 10 2016 201 497 A1 covers a retrofittable anti-theft module for battery-powered power tools, which includes a positioning unit and transmits position data to an external device. The module is installed as an adapter between the power tool's battery interface and the battery. Positioning can be achieved using location services such as GPS or networks such as Wi-Fi. The anti-theft module can, for example, use geofencing to trigger an alarm or initiate actions when a predefined area is left.

[0016] DE 10 2010 041 309 A1 discloses an anti-theft device for a mobile device with a shutdown unit, which is characterized by an applicant: LUKAS Hydraulik GmbH

[0019] A positioning unit for determining the current position and an evaluation unit for processing it. Position determination can be achieved using transmitters located on Earth or geodetic satellites. The evaluation unit should include information input, processing, and output, and should contain at least one processor, memory, input and output devices, control routines, and / or calculation routines. In the event of an invalid position being entered, the device can be disabled via the shutdown unit.

[0020] US patent 2014 140 125 A1 discloses a method for tracking the position of tools using a monitoring unit, such as a smartphone or PC. The monitoring unit includes a geofencing unit, which allows a permitted area to be set for one or more tools. After determining the tool's position via GPS, location data can be sent to the monitoring unit, which then determines whether the tool is within the defined boundaries. If the tool is outside the boundaries, the geofencing unit automatically sends a signal to the tool to deactivate it or reduce its power. The tool itself can also periodically check whether it remains within the permitted area after receiving the geofencing boundaries from the monitoring unit.

[0021] Object of the present invention

[0022] The object of the present invention is to provide a generic working device and an arrangement comprising a working device and an input device, which, with simple implementation, effectively prevents misuse. Applicant: LUKAS Hydraulik GmbH

[0025] Solution to the problem

[0026] The above problem is solved by the features of claims 1 and 15. Advantageous embodiments of the present invention are claimed in the further claims.

[0027] According to the invention, the electronic control unit automatically disables the operational capability of the work device based on the entered configuration data and at least one locking criterion. No external command is required for locking. The work device operates autonomously. Locking means that the work device cannot be used while locked.

[0028] According to the invention, a blocking criterion relates to a violation of a GNSS geofence configured in the work device using GNSS geofence configuration data by a position of the work device determined by the work device. Such a violation occurs in particular when the work device crosses the GNSS geofence defined in the work device, for example, because it is moved from the theft site to an area outside the GNSS geofence after a theft. The work device automatically detects such a violation of the GNSS geofence and blocks the work device. This is the GNSS mode.

[0029] Alternatively or additionally, a further blocking criterion can be whether or not the work device logs into a radio network known to it. Such work devices are typically operated within radio range of networks known to them. These networks are operated on emergency vehicles (e.g., fire engines, police vehicles, military vehicles) or on buildings (e.g., fire stations, police stations, military stations) by means of a radio transmitter / receiver located there. This is the network mode. Applicant: LUKAS Hydraulik GmbH

[0032] Preferably, the wireless network is a WLAN network known to the device. For example, a Wi-Fi 6 (IEEE-802.11ax) wireless network can be used.

[0033] If the device cannot find a known wireless network, this indicates that it has been stolen from the aforementioned areas. A wireless geofence is then established for the device, providing additional security. The device also performs this blocking check automatically. Even greater security is achieved when both of the aforementioned blocking criteria are used in combination.

[0034] According to a preferred embodiment of the present invention, a "radio network known to the working device" can be such a radio network whose SSID, preferably its SSID and network password, is known to the working device. The working device can log into this known radio network if it knows the SSID and network password. If the working device knows the SSID and network password of the radio network, special protection is ensured.

[0035] According to a preferred embodiment of the present invention, a first time window (radio short-term) can be entered as configuration data in the working device, which defines a period of time in which the working device remains unlocked after logging into the radio network known to the working device.

[0036] According to a preferred embodiment of the present invention, the working device can store the time of a previous or last login of the working device into the radio network known to the working device in the data memory, the working device compares the stored time of the previous or last login of the working device into the radio network known to the working device with the first time window, wherein a blocking criterion determines the temporal position of the time of the previous or last login of the working device into the applicant: LUKAS Hydraulik GmbH

[0038] - 6 -

[0039] The system determines whether the device is connected to a known wireless network compared to the first time window. If the time of the earlier or last login falls within the first time window, it can be assumed that the device is in an authorized area, making a lock unnecessary. If the time of the earlier or last login falls outside the first time window, there is a risk of misuse, and the device will lock itself automatically. If no misuse has occurred, the device can be unlocked at any time by an authorized user.

[0040] According to an advantageous embodiment of the present invention, the time of the earlier or last login of the working device into the radio network known to the working device (e.g., of a fire engine) can be overwritten in the data memory by the next subsequent time of a login of the working device into the radio network known to the working device or into another radio network known to the working device (e.g., in the fire station).

[0041] According to a preferred embodiment of the present invention, a second time window can be entered as configuration data in the device, defining a time period. A blocking criterion includes a check of the device to determine whether the second time window is exceeded during the search for a GNSS signal without finding one. In particular, this allows a time-out to be configured in the control unit, causing the device to lock itself if no GNSS signal is found within the second time window, for example, because an attempt has been made to circumvent the GNSS geofencing by interrupting the GNSS signal.

[0042] According to a preferred embodiment of the present invention, a third time window can be entered as configuration data in the working device, which defines a time period, wherein a blocking criterion relates to the temporal position of the time of the earlier or last login of the working device to the radio network known to the working device in comparison to the third time window. Preferably, this third time window is provided in a combination mode. Applicant: LUKAS Hydraulik GmbH

[0044] - 7 - which provides a combination of a network mode and a GNSS mode.

[0045] According to a preferred embodiment of the present invention, in combination mode the network mode is weighted more heavily than the GNSS mode.

[0046] The third time window (long-term radio) is longer than the first time window (short-term radio). If the time of the device's previous or last login to the known radio network falls outside the first time window but still within the third, the GNSS position or geofence is checked. This involves searching for the GNSS signal within the second time window, which serves as a timeout for the signal. If the time of the device's previous or last login to the known radio network falls outside the third time window, the device is locked, preferably regardless of whether it is inside or outside the GNSS geofence.If the time of the earlier or last login of the work device to the radio network known to the work device falls within the first time window, the work device is unlocked, preferably regardless of whether it is located inside or outside the GNSS geofence.

[0047] According to a preferred embodiment of the present invention, the testing of the at least one blocking criterion by the working device can be carried out over a limited period of time during the commissioning of the working device. For example, the commissioning of the working device can be effected by inserting the battery into the battery compartment of the working device or by switching on the working device.

[0048] According to an advantageous embodiment of the present invention, the time of a previous or last login of the work device to a radio network known to the work device can be determined during commissioning and compared with the current time. Applicant: LUKAS Hydraulik GmbH

[0050] - 8 -

[0051] When searching for a GNSS signal within the second time window, the time-out countdown continues even if the device is switched off. Otherwise, it is reset to a selected value and restarted. Therefore, switching off the device does not interrupt the control process.

[0052] According to a convenient embodiment of the present invention, preferably during initial configuration, a router mode for establishing a connection and entering configuration data into the data memory of the working device can be called up via the working device.

[0053] According to a convenient embodiment of the present invention, the router mode is also active when the device is locked. This enables the device to be unlocked quickly.

[0054] According to a preferred embodiment of the present invention, the router mode can be called up using at least one handle provided on the working device, preferably using the hydraulic switching valve and / or an on / off switch.

[0055] According to a convenient embodiment of the present invention, the last determined position of the working device can be used to check the position of the working device determined by the working device in relation to the GNSS geofence entered in the working device.

[0056] According to a convenient embodiment of the present invention, the following geo-configuration data can be entered into the data memory of the working device by the user:

[0057] The coordinates of the current location or the coordinates of a freely selectable position (e.g., a fire station), preferably as latitude and longitude, for defining the center position of the GNSS geofence, and / or applicant: LUKAS Hydraulik GmbH

[0059] - 9 - the extent area around the center position of the GNSS geofence, and / or a password, and / or the first time window, and / or the second time window, and / or the third time window.

[0060] According to a preferred embodiment of the present invention, the electronic control unit can be configured such that the calculation of the work device's position takes place exclusively within the work device, and / or the comparison of the work device's position with the GNSS geofence takes place exclusively within the work device, and / or no position data is transmitted from the work device via an uplink for the comparison of the work device's position with the GNSS geofence. This results in a very simple implementation of the measures to prevent the misuse of work devices. For ongoing monitoring regarding the application of the various blocking criteria, the data remains within the work device. An additional advantage of these measures is that they do not violate any data protection regulations.

[0061] According to a preferred embodiment of the present invention, the electronic control unit can be configured such that it automatically unlocks the work device when the work device located outside the GNSS geofence is returned to the GNSS geofence, and / or when the work device located outside the GNSS geofence is returned to the GNSS geofence, the time stored in the data memory of a previous or last login of the work device to the radio network known to the work device lies within the third time window and the work device is not connected to the radio network known to the work device, and / or Applicant: LUKAS Hydraulik GmbH

[0064] The present invention further relates to an arrangement comprising a working device according to any one of claims 1 to 14 and an input device, in particular an input device having a display, for example in the form of a smartphone, tablet or PC. The input device enables the working device to be configured with respect to the blocking criteria via radio transmission, preferably via WLAN radio transmission.

[0065] According to a convenient embodiment of the present invention, apart from establishing the radio connection for entering the configuration data, no further data transmission takes place from the working device to the input device.

[0066] According to a convenient embodiment of the present invention, the working device generates its own wireless network in a router mode for data transmission with its own SSID, into which the input device can log in and access configuration pages or the configuration mode.

[0067] According to a preferred embodiment of the present invention, a configuration mode can be accessed on the input device, wherein the configuration mode can be, in particular, a GNSS mode, a network mode, and / or a combination of GNSS and network modes. Additionally, a mode can also be selected in which no monitoring of the working device according to blocking criteria takes place. Applicant: LUKAS Hydraulik GmbH

[0102] Fig. 1 shows a perspective view of an example of an electro-hydraulic portable tool 100 in the form of a so-called Rapid Intervention Tool (RIT Tool). The tool has a portable base 101, which includes an electric motor 102, preferably a brushless DC motor, that drives a hydraulic pump 104. The hydraulic pump 104 moves a piston rod (not shown in Fig. 1) of a hydraulic cylinder 131, the movement of which, by means of a suitable power transmission device, leads to the opening or closing of the tool tips of the tool 100. Reference numeral 129 designates the housing of the tool 100.

[0103] In the example of the working device 100 shown in Fig. 1, the tool tips comprise cutting tool halves 130, onto which spreading tool halves 128 are each attached. Furthermore, the working device 100 comprises a handle 113 and an electric battery 103, which can be inserted into a receiving slot (not shown in Fig. 1) to supply the electric motor 102 with electrical energy.

The switching valve can, for example, have a so-called star knob, where the switching positions can be controlled by turning the star knob.

[0107] Due to the portable base unit 101, the work device can be operated autonomously, i.e., it does not require a drive unit connected via hoses.

[0108] The electro-hydraulic working device shown in Fig. 1 is merely an example. Within the scope of the invention, the working device 100 can equally well be a cutting device, a spreading device, a so-called combination device enabling both spreading and cutting, or even a rescue cylinder.

[0109] Fig. 2 shows, in a highly simplified schematic representation, the essential functional components of a portable work device 100 according to the present invention. The electric battery 103 serves to supply energy to the electric motor 102 and the components of the control unit 110. The electric motor 102 drives the hydraulic pump 104. The hydraulic pump 104 is connected to a hydraulic tank 105 via hydraulic lines 106. The latter contains a supply of hydraulic fluid 109 for driving the piston rod 107 of the hydraulic cylinder 131. The hydraulic switching valve 111 is positioned between the pump 104 and the hydraulic cylinder 131. To allow for compensation of the volume of hydraulic fluid 109 due to the movement of the piston rod 107 in the hydraulic cylinder 131, a so-called compensating device 108 is provided. This can be arranged as a flexible diaphragm in the hydraulic tank 105 or be part of the hydraulic tank 105.

[0114] Working tool. The spreading tool halves 128 and cutting tool halves 130 are shown in closed position in Fig. 2.

[0115] Reference numeral 110 identifies the control unit as a whole. It serves to control the operation of the work device 100. The control unit comprises a main processor 148, a data storage device 112, a processor 149 for motor control, and a GNSS signal acquisition and evaluation unit 114, which is capable of receiving and evaluating GNSS signals 115. Furthermore, a radio data interface 116 is provided, which is capable of receiving radio telegrams 155. The main processor 148 serves to control the main functions of the work device and the output of information to a display 156. The radio data interface 116 serves to receive configuration data before an input device. Preferably, this is a WLAN radio data interface. For example, a Wi-Fi 6 data interface according to the IEEE 802.11ax standard can be provided for this purpose.

[0116] The control unit 110 is connected to the electric battery 103 via a data line 157, enabling monitoring measures such as charge level checks. The control unit 110 is also connected to the electric motor 102 to ensure its basic control. In the case of a brushless DC motor, the stator magnetization is controlled by the additional motor control processor 149. Therefore, a control line 153 is provided between the electric motor 102 and the control unit 110. The control line 154 connects the switching valve 111 to the control unit 110.

[0117] The GNSS signal acquisition and evaluation device 114 enables the position determination of the work tool 100 by receiving GNSS signals 115. For example, GNSS signals 115 include GPS, GLONASS, or GALILEO signals. Applicant: LUKAS Hydraulik GmbH

[0120] According to the invention, the working device 100 can be configured in a special way to prevent or at least make misuse more difficult. Such configuration can be carried out in a particularly simple manner using an input device 122, in particular a smartphone, tablet, or PC. In Fig. 3, for example, a smartphone with a display 138 is shown as the input device 122. According to Fig. 3, the input device 122 is able to communicate with the radio data interface 116 of the working device 100 via a radio connection 127 (e.g., a WLAN radio connection). This allows data to be entered into the input device 122, transmitted to the working device 100 by means of a radio telegram 155, and stored there in the data memory 112 as configuration data.

[0121] Data transmission between the input device 122 and the work device 100 via the radio link 127 is, in particular, at least essentially unidirectional. For data transmission, the work device 100 generates its own radio network with its own SSID, into which the input device 122 can log in and access configuration pages. Advantageously, no internet connection is required for configuration.

[0122] To trigger such a mode for transferring configuration data from the input device 122 to the working device 100, either a handle can be provided on the working device 100, or a corresponding action can be triggered by means of at least one existing handle. For example, such a mode can be activated by actuating (e.g., turning) the hydraulic switching valve 111 and simultaneously actuating the on / off switch 152. The router mode is active when the working device 100 is locked to enable rapid access, e.g., by entering the password.

[0123] The configuration data to be transmitted includes, for example, a simplified GNSS geofence 117 shown in Fig. 4. This geofence is an area with a center position 119 and a GNSS geofence radius 134. The center position 119 is defined by the intersection point of a line of longitude.

[0126] The latitude and longitude are set at 120° and 121°. This data is entered into the input device 122 and transferred to the working device 100.

[0127] Reference numeral 118 indicates the current position of the working device 100. In the situation shown in Fig. 4, the working device 100 is located at position 118 within the GNSS geofence 117, but not at the center position 119 of the GNSS geofence 117. The determination of position 118 is made possible when at least one, preferably several, GNSS signals 115 from one or more satellites in orbit are received by the working device 100. The current position 118 of the working device 100 can be shifted to the center position by means of input on the input device 122.

[0128] Figure 5 shows an alternative radio range geofence 158, which is defined by the range 126 of the radio network (e.g., a WLAN network). This network is established, for example, by a radio communication router 133, which can be located, for instance, on an emergency vehicle or at a local facility (fire station). This radio communication router 133 provides a radio network that is known to the device 100, as the device 100 knows its SSID and network password ("known radio network"). Radio communication routers 137 of unknown radio networks have no influence on the operation or operating state of the device 100. The device 100 is able to log in to the known radio network of the radio communication router 133. This ability to log in indicates that the device 100 is located within the radio range geofence 158.

[0129] The electronic control unit 110 is configured based on the entered configuration data such that it automatically disables the operation of the working tool 100 based on at least one blocking criterion. For this purpose, the electronic control unit 110 is configured such that the calculation of the working tool 100's position is performed exclusively within the working tool or the electronic control unit 110, and / or the applicant: LUKAS Hydraulik GmbH

[0130] Title: Portable work device and arrangement consisting of a STIPPL patent attorneys portable work device and an input device 18.12.2024 240073PCT

[0131] - 18 - equal to the position of the work device 100 with the GNSS Geofence 117 exclusively in the work device, and / or for the comparison of the position of the work device 100 with the GNSS Geofence 117 no position data are sent from the work device to the input device 122.

[0132] Fig. 6 shows an example of the operation of the work device 100 in network mode 140, which has already been explained with reference to Fig. 5. When the work device is put into operation, for example by inserting the electric battery 103 into the socket provided for this purpose on the work device 100 or by pressing the on / off switch 152, the router mode can first be activated. Then the network mode 140 can be configured on the input device 122. As soon as the work device is put into operation, the radio range geofence 158 is initialized. Here, the time of the last contact stored in the data memory 112 (e.g., Log in 27.11.2024, 12:00) is compared with the first time window 142 (radio short-term). In the case according to Fig. 6a, this first contact lies within the first time window 142. In this case, the work device unlocks itself automatically.

[0133] If the time of the last contact (e.g., log in on November 27, 2024, at 10:00 AM) falls outside the first time window 142, i.e., before it, the device locks itself automatically. The device can be unlocked by entering a password in network mode. This requires a login. This login overwrites the previous login, i.e., time 143 of the last login in data memory 112. Therefore, this overwritten time is the relevant time for subsequent startup.

[0134] Alternatively, GNSS mode 139 can be selected and configured on input device 122. Upon commissioning, the work tool searches for GNSS signals in its vicinity within a second time window 146. If the work tool receives at least one GNSS signal within this second time window 146, it checks whether the position resulting from the received GNSS signal is within the GNSS area. Applicant: LUKAS Hydraulik GmbH

[0135] Title: Portable work device and arrangement consisting of a STIPPL patent attorneys portable work device and an input device 18.12.2024 240073PCT

[0136] - 19 - ofence. If the device is inside the GNSS geofence, it remains unlocked. If it is outside the GNSS geofence, it locks itself.

[0137] A corresponding position query is performed continuously. A subsequent interruption of a satellite connection has no influence on the result of the query, as the last known position is used for the calculation.

[0138] If no GNSS signal is received within the second time window (146) (see Fig. 7b) or if the device leaves the GNSS geofence, it locks itself automatically. The device can be unlocked by entering a password in network mode, by relocating the GNSS geofence in network mode, or by returning the device to the inside of the GNSS geofence.

[0139] Fig. 8 shows a combination mode 141 that combines GNSS mode 139 and network mode 140. This combination mode 141 additionally includes a third time window 150 (long-term radio signal) to provide an assignment in case the last log in is further in the past than the first time window 142. If the last log in is further in the past than the third time window 150 or long-term radio signal (position (a) in Fig. 8), the device is locked, regardless of its current location. It therefore remains locked even if, for example, it is inside the GNSS geofence. If the last log in is within the third time window 150 or long-term radio signal (position (b) in Fig. 8), the device 100 searches for a GNSS signal and determines its current position to check whether it is inside or outside the GNSS geofence.

[0140] The verification of the blocking criteria according to network mode 140, GNSS mode 139, and combination mode 141 preferably takes place exclusively during the commissioning of the work device 100. Timeouts of the respective time-applicant: LUKAS Hydraulik GmbH

[0141] Title: Portable work device and arrangement consisting of a STIPPL patent attorneys portable work device and an input device 18.12.2024 240073PCT

[0142] - 20 - Windows 142 and 150 are not recorded during operation. If the work device 100 performs a lock, this is stored in the work device's data memory 112. The work device remains locked even after a restart.

[0143] Figure 9 shows example input masks on the display 146 of the input device 122 for different modes. To determine the position, the user can enter the latitude 121 and longitude 120 (for example, the latitude and longitude of the fire station) and set this as the current position. Furthermore, the user can enter the area 134 that will encompass the GNSS geofence around this current position.

[0144] In Fig. 9a, this is an area 134 of 0.1 km. This defines the radius of the GNSS geofence 117. Furthermore, the user can freely define the length of the second time window 146, i.e., the length of the timeout. In the example shown in Fig. 9a, the length is 60 minutes. Additionally, the password 125 can be entered via the input mask.

[0145] Additionally, a map display is shown on display 138 with the currently entered position marked as a point. Alternatively, instead of entering specific latitude and longitude coordinates, the current location can also be selected using the "Set current position" button.

[0146] Once all data has been entered, the user can save it by clicking the "Save" button. The saved configuration data is then transmitted as radio telegram 155 to the work device and stored there.

[0147] Fig. 9b shows network mode 140. In this mode, the length of the first time window 142 can be entered. In the example of Fig. 9b, this is one hour. The password 125 can also be entered in this mode. The entered data can be saved using the save button and written to the device. Applicant: LUKAS Hydraulik GmbH

[0149] - 21 -

[0150] The input mask for combination mode 141 in Fig. 9c differs from the input mask for GNSS mode 139 in Fig. 9a in that, in addition to the second time window 146, the first time window 142 and the third time window 150 can be entered. In the example shown in Fig. 9c, the third time window 150 is 48 hours. A password 125 can also be entered in this mode.

[0151] The present invention makes it possible to provide a portable work device with very little implementation effort, which effectively prevents misuse or at least makes it considerably more difficult. The present invention therefore represents a very special contribution to the relevant field of technology.
