Description

Technical Field

[0001] The present invention relates to a method and a system for automatically assisting in the repair of motor-driven tools. Summary of the Invention

[0002] The purpose of this invention is to provide a method and a system for automatically assisting in the repair of motor-driven tools.

[0003] This invention achieves this objective by providing a method and / or a system according to the invention. Advantageous modifications and / or designs of the invention are described in other parts of this disclosure.

[0004] The method according to the invention is designed or configured for automatic assistance during the maintenance (especially maintenance-acceptance) of motor-driven tools. The method includes or has the following steps: a) detecting (especially automatically detecting), especially detecting and / or receiving at least one operating edge condition (especially the value of the operating edge condition) of the tool, wherein the tool previously did not (especially no longer) operate in accordance with regulations, or even did not (especially no longer) operate, under such operating edge condition or circumstance; b) determining (especially automatically determining) a set of possible or probable symptoms of failure and / or possible or probable causes of failure and / or possible or probable maintenance instructions and / or possible or probable spare parts based on the detected operating edge condition; c) outputting (especially automatically outputting) the determined set of possible symptoms of failure and / or possible causes of failure and / or possible maintenance instructions and / or possible spare parts to or to the user and / or maintenance personnel of the tool.

[0005] This (especially the detection of operational edge conditions) enables the indirect identification of the set of possible fault symptoms and / or possible causes of failure and / or possible maintenance instructions and / or possible spare parts. Additionally or alternatively, this (especially “outputting the identified set of possible fault symptoms and / or possible causes of failure and / or possible maintenance instructions and / or possible spare parts”) enables maintenance to be performed quickly and therefore cost-effectively, or even completely, by a maintenance worker.

[0006] In particular, the tool can be a hand-held (especially portable) tool. A hand-held (especially portable) tool can specifically mean that the tool can have a mass of up to 50 kg, especially up to 20 kg, especially up to 10 kg, especially up to 5 kg, and / or a minimum of 1 kg, especially a minimum of 2 kg. Additionally or alternatively, the tool is a gardening tool, a forestry tool, and / or a construction tool.

[0007] The detection can be carried out by means of a detection device. In particular, the detection device can be constructed separately from the tool. In other words, the detection device does not need to be, or may not be, a component of the tool.

[0008] Operating edge conditions can be such that it becomes possible to determine the set of possible fault symptoms and / or possible fault causes and / or possible maintenance instructions and / or possible spare parts. In other words, operating edge conditions can be relevant to the non-functionality of the tool. Additionally or alternatively, at least one other operating edge condition that is not relevant or irrelevant, especially to the non-functionality of the tool, can be identified.

[0009] Based on the known operating edge conditions (especially the known operating edge condition values), a set of possible fault symptoms and / or possible causes of failure and / or possible maintenance instructions and / or possible spare parts for the tool can be determined, and based on another known operating edge condition (especially another known operating edge condition value), another set of possible fault symptoms and / or possible causes of failure and / or possible maintenance instructions and / or possible spare parts for the tool can be determined.

[0010] The set may have at least (especially only) one (especially unique) possible fault symptoms and / or at least (especially only) one (especially unique) possible fault causes and / or at least (especially only) one (especially unique) possible maintenance instructions and / or at least (especially only) one (especially unique) possible spare parts. Additionally or alternatively, another set of impossible fault symptoms and / or impossible fault causes and / or impossible maintenance instructions and / or impossible spare parts for the tool may be output, particularly based on the fact that the known operating edge conditions are not determined, and in particular, this allows the user and / or maintenance personnel to distinguish between the set and the other, for example, by means of priority.

[0011] The output can be acoustic and / or optical, especially a display.

[0012] Step b) may be performed after step a) in time. Alternatively or concurrently, step c) may be performed after step b) in time.

[0013] In one improvement of the invention, the tool does not include or has (especially electrical) fault sensors and / or (especially electrical) fault memories. This allows the tool to be constructed simply and therefore cost-effectively.

[0014] In an improved embodiment of the invention, the set of possible fault symptoms can be selected by the user. The method includes or has the following steps: d) selecting, in particular by the user and / or the repairman, from a determined (in particular, output) set of possible fault symptoms selectable by the user, or selecting (in particular, only) one (in particular, unique) fault symptom; e) determining (in particular, automatically) a set of possible or probable causes of tool failure and / or possible or probable maintenance instructions and / or possible or probable spare parts based on the selected fault symptom; f) outputting (in particular, automatically) the determined set of possible causes of failure and / or possible maintenance instructions and / or possible spare parts, in particular to or to the user and / or the repairman. This enables maintenance to be performed particularly quickly and therefore particularly cost-effectively. In particular, possible causes of failure and / or possible maintenance instructions and / or possible spare parts for the set of tools can be determined based on selected fault symptoms, and other possible causes of failure and / or possible maintenance instructions and / or possible spare parts for another set of tools can be determined based on another selected fault symptom. Additionally or alternatively, the set may have at least (especially only) one (especially unique) possible cause of failure and / or at least (especially only) one (especially unique) possible maintenance instruction and / or at least (especially only) one (especially unique) possible spare part. Furthermore, additionally or alternatively, another set of impossible causes of failure and / or impossible maintenance instructions and / or impossible spare parts for the tools can be output, especially based on the fact that the selected fault symptoms have not been determined, so that it can be distinguished between the set and the other, especially by the user and / or repairman, for example, by means of priority. Furthermore, additionally or alternatively, the output may include acoustic and / or optical output, especially a display. Furthermore, additionally or alternatively, step d) may be performed temporally after step c). Additionally or alternatively, step e) may be performed after step b) in time. Additionally or alternatively, step f) may be performed after step e) in time.

[0015] In one improvement of the invention, the operating edge conditions include or include meteorological parameters of the tool's operating environment, particularly air pressure, humidity, precipitation, and / or temperature, and / or altitude and / or location. The altitude can, in particular, exceed sea level. This enables particularly effective identification of possible symptoms and / or causes of failure for the set of tools and / or possible maintenance instructions and / or available spare parts. In other words, such operating edge conditions can be particularly relevant to non-functionality of the tools.

[0016] In one embodiment of the invention, step a) includes or comprises: detecting (especially automatically detecting), especially the altitude (especially altitude value) and / or position (especially position value) of the operating environment of the tool, and detecting (especially automatically detecting) meteorological characteristic parameters based on the detected altitude and / or detected position. This achieves indirect detection of meteorological characteristic parameters.

[0017] In one improvement of the invention, the tool includes or has an internal combustion engine drive system. This internal combustion engine drive system operates non-compliantly prior to the stated operating edge conditions. This group includes possible symptoms and / or possible causes of failure of the internal combustion engine drive system and / or possible maintenance instructions and / or possible spare parts for the internal combustion engine drive system. In particular, meteorological characteristic parameters may be especially relevant to the non-compliant functioning of the internal combustion engine drive system. Additionally or alternatively, the tool may have a machining tool, and the internal combustion engine drive system may be configured to drive the machining tool.

[0018] In one embodiment of the invention, the internal combustion engine drive system includes or has a mixture preparer (especially a carburetor) and / or spark plugs and / or valves (especially fuel inlet valves, especially fuel injection valves) and / or a clutch.

[0019] In one improved embodiment of the invention, the tools are saws, high-post trimmers, brush cutters, hedge trimmers, hedge cutters, blowers, leaf blowers, pruning shears, grinders, sweepers, sweeping rollers, sweeping brushes, lawn mowers, soil looseners, lawn mowers, shredders, stone cutters, high-pressure cleaners or jetters and / or sprayers.

[0020] In one improved embodiment of the invention, the method includes or has the following steps: detecting (especially automatically detecting) the type of the detection and / or receiving tool. The method includes or has the following steps: determining (especially automatically determining) a set of possible fault symptoms and / or possible fault causes and / or possible maintenance instructions and / or possible spare parts based on the detected type. This achieves the avoidance of determining (especially outputting) irrelevant (especially unlikely) fault symptoms and / or irrelevant (especially unlikely) fault causes and / or irrelevant (especially unlikely) maintenance instructions and / or irrelevant (especially unlikely) spare parts for the detected type. The type of tool can, in particular, come from a large number of different motor-driven tool types.

[0021] In one embodiment of the invention, "detecting the type of tool" includes or has the following features: selecting (especially automatically) or choosing (especially only) (especially uniquely) a tool type from a large number of different motor-driven tool types, particularly by the user and / or repairman. This achieves a high degree of user- and / or repairman-friendliness.

[0022] In an improved embodiment of the invention (especially a design embodiment), the determination includes or comprises: selecting (especially automatically) or selecting a set of possible fault symptoms from a large number of different fault symptoms, wherein the fault symptoms are correspondingly associated with at least one operating edge condition (especially operating edge condition value) from a large number of different operating edge conditions (especially different operating edge condition values), especially and at least one tool type (if present) from a large number of different tool types. Additionally or alternatively, the determination includes or comprises: selecting (especially automatically) or selecting a set of possible fault causes and / or possible maintenance instructions and / or possible spare parts from a large number of different fault causes and / or different maintenance instructions and / or different spare parts, wherein the fault causes and / or maintenance instructions and / or spare parts are correspondingly associated with at least one operating edge condition (especially operating edge condition value) from a large number of different operating edge conditions (especially different operating edge condition values), and / or at least one fault symptom (if present) from a large number of different fault symptoms, especially and at least one tool type (if present) from a large number of different tool types. This enables the determination of the set of possible fault symptoms and / or possible causes of failure and / or possible maintenance instructions and / or possible spare parts based on the detected operating edge conditions and / or selected fault symptoms (especially the detected types).

[0023] In one embodiment of the invention, the method includes or has the following steps: particularly during and / or after maintenance, especially by the user and / or maintenance personnel, identifying the actual symptoms of tool failure and / or the actual cause of failure and / or the actual maintenance instructions and / or the actual spare parts; for the subsequent implementation of the method, associating (particularly automatically) at least one operating edge condition with the identified actual symptoms of failure, and / or associating (particularly automatically) at least one operating edge condition and / or (particularly selected and / or actual) symptoms of failure (if present) with the identified actual cause of failure and / or the identified actual maintenance instructions and / or the identified actual spare parts. This achieves a particularly gradual improvement to the method. In particular, “identifying actual fault symptoms and / or actual fault causes and / or actual maintenance instructions and / or actual spare parts” may include: confirming or changing a determined (especially output) set of possible fault symptoms and / or possible fault causes and / or possible maintenance instructions and / or possible spare parts.

[0024] As previously stated, the method according to the invention is designed or configured for automatic assistance during the maintenance (especially maintenance-acceptance) of, in particular, motor-driven tools. The method includes or has the following steps: detecting (especially automatically detecting), in particular receiving at least one operating condition of the tool (especially operating condition value), in particular a running-speed-frequency distribution (especially a running-speed-frequency distribution value), in particular until the tool no longer (especially no longer) operates in accordance with specifications, or even no longer (especially no longer) operates; based on the detected operating conditions, determining (especially automatically determining) a set of possible or probable fault symptoms and / or possible or probable fault causes and / or possible or probable maintenance instructions and / or possible or probable spare parts for the tool; outputting (especially automatically outputting) the determined set of possible fault symptoms and / or possible fault causes and / or possible maintenance instructions and / or possible spare parts to or to the user and / or maintenance worker.

[0025] This, in particular "detecting operating conditions," enables the indirect identification of the set of possible fault symptoms and / or possible causes of failure and / or possible maintenance instructions and / or possible spare parts. Additionally or alternatively, this, in particular "outputting the identified set of possible fault symptoms and / or possible causes of failure and / or possible maintenance instructions and / or possible spare parts," enables maintenance to be performed quickly and therefore cost-effectively, or even completely, by the maintenance personnel.

[0026] In particular, at least one operating condition does not require or may not be a fault. Additionally or alternatively, at least one operating edge condition and at least one operating condition may be different, especially of different types.

[0027] Operating conditions can be configured such that the set of possible fault symptoms and / or possible causes of failure and / or possible maintenance instructions and / or possible spare parts can be determined. In other words, operating conditions can be relevant to non-standard operation of the tool. Additionally or alternatively, at least one other operating condition (especially one that is not relevant or irrelevant to non-standard operation of the tool) can be identified.

[0028] Based on the known operating conditions (especially the known operating condition values), the aforementioned set of possible fault symptoms and / or possible causes of failure and / or possible maintenance instructions and / or possible spare parts for the tool can be determined, and based on another known operating condition (especially another known operating condition value), another set of possible other fault symptoms and / or possible other causes of failure and / or possible other maintenance instructions and / or possible other spare parts for the tool can be determined.

[0029] The set may have at least (especially only) one (especially unique) possible fault symptoms and / or at least (especially only) one (especially unique) possible fault causes and / or at least (especially only) one (especially unique) possible maintenance instructions and / or at least (especially only) one (especially unique) possible spare parts. Additionally or alternatively, another set of impossible fault symptoms and / or impossible fault causes and / or impossible maintenance instructions and / or impossible spare parts for the tool may be output, particularly based on the fact that the known operating edge conditions are not determined, and in particular, this allows for differentiation between the set and the other, especially by the user and / or maintenance personnel, for example, by means of priority.

[0030] The output can be acoustic and / or optical, especially a display.

[0031] It can be determined that the action can be taken after the discovery. Alternatively, the output can be taken after the determination.

[0032] The system according to the invention (especially electric) is designed or configured for automatic assistance in the maintenance (especially maintenance-acceptance) of, particularly motor-driven tools, especially for implementing the methods described above. The system includes or has, particularly electric, a detection device, a determination device, and a, particularly electric, output device. The detection device is designed or configured to, particularly automatically, detect at least one (especially the at least one) operating edge condition of the tool, wherein the tool has not previously operated in accordance with the prescribed conditions. The determination device is designed or configured to, particularly automatically, determine, based on the detected operating edge condition, particularly the set of possible fault symptoms and / or possible causes of failure and / or possible maintenance instructions and / or possible spare parts for the tool. The output device is designed or configured to, particularly automatically, output the determined set of possible fault symptoms and / or possible causes of failure and / or possible maintenance instructions and / or possible spare parts, particularly to or to the user and / or maintenance worker.

[0033] In particular, the system can have a mobile (especially portable or handheld) device, which may have a sensing device, a determining device, and / or an output device. Specifically, the mobile device can be a smartphone and / or a smartwatch. Additionally or alternatively, the mobile device can be constructed separately from the tool. In other words, the mobile device need not be, or may not be, a component of the tool.

[0034] In one improved embodiment of the invention, the system includes or has tools. Attached Figure Description

[0044] The method comprises the following steps: a) detecting, in particular, at least one operating edge condition RB of the tool 2 by means of the detection device 3, wherein the tool 2 has not previously operated in accordance with the specified conditions under the operating edge condition RB, such as Figure 1 , 2 As shown in Figure 7; b) Based on the detected operating edge conditions RB, especially by means of the determining device 4, determine the set of possible failure symptoms mFS and / or possible failure causes mFU and / or possible maintenance instructions mRA and / or possible spare parts mET for tool 2, such as Figure 1 , 3 As shown in 7; c) particularly by means of output device 5, a determined set of possible fault symptoms mFS and / or possible fault causes mFU and / or possible maintenance instructions mRA and / or possible spare parts mET are output to or to the user and / or repairer of tool 2, such as Figure 1 , 2 As shown in 4 and 7.

[0045] Additionally or alternatively, the method includes the following steps: in particular, detecting at least one operating condition BB of the tool 2 (operation-speed-frequency distribution nHV in the illustrated embodiment) using the detection device 3, such as... Figure 5 As shown, especially until tool 2 operates incorrectly, such as Figure 1 and 2 As shown; based on the known operating conditions BB, and especially with the aid of the determining device 4, the set of possible fault symptoms mFS and / or possible fault causes mFU and / or possible maintenance instructions mRA and / or possible spare parts mET for tool 2 are determined, such as Figure 1 and 6 As shown in the figure; in particular, by means of output device 5, a set of possible fault symptoms mFS and / or possible fault causes mFU and / or possible maintenance instructions mRA and / or possible spare parts mET are output.

[0046] In the illustrated embodiment, system 1 has a mobile device 30, particularly in the form of a smartphone. The mobile device 30 has one of a detection device 3 and an output device 5, particularly in the form of a display.

[0047] Furthermore, system 1 has fixed equipment 35, particularly in the form of a computer, especially in the workshop, such as... Figure 4 As shown in the diagram, the fixed device 35 has one of the output devices 5, particularly in the form of a display.

[0048] Furthermore, it was determined that device 4 is in the form of a cloud-server.

[0049] In addition, the detection device 3 and the determination device 4 are configured to (especially wirelessly) transmit the detected operating edge condition RB and / or the detected operating condition BB.

[0050] Furthermore, the determining device 4 and the output device 5 are configured to transmit, in particular wirelessly, a set of possible fault symptoms mFS and / or possible fault causes mFU and / or possible maintenance instructions mRA and / or possible spare parts mET.

[0051] In addition, System 1 has Tool 2.

[0052] In the illustrated embodiment, tool 2 has a running condition memory 40 for storing at least one running condition BB, such as Figure 1 and 4 As shown in the diagram, the detection device 3 and the operating condition memory 40 are configured for transmitting operating conditions BB, particularly wirelessly.

[0053] In detail, tool 2 does not have a fault sensor and / or fault memory.

[0054] exist Figures 1 to 6 In the middle, tool 2 is saw 2'.

[0055] exist Figure 7 In the middle, tool 2 is pruning shears 2.

[0056] In addition Figure 7 In this context, tool 2 has an electric motor drive system 19. The electric motor drive system 19 has not previously operated in accordance with specifications under the operating edge condition RB. This group includes possible fault symptoms mFS and / or possible causes of failure mFU from the electric motor drive system 19 and / or possible maintenance instructions mRA and / or possible spare parts mET for the electric motor drive system 19.

[0057] In detail, the electric motor drive system 19 has a transmission device 20, particularly a ball screw, ball nut and / or pinion gear set.

[0058] In particular, Figure 7 In the middle, tool 2 is battery tool 2”'.

[0059] In addition, Figures 1 to 6 In this context, tool 2 includes an internal combustion engine drive system 10. The internal combustion engine drive system 10 is operating under the operating edge condition RB, which has not previously met specifications. This group includes possible symptoms of failure mFS and / or possible causes of failure mFU and / or possible maintenance instructions mRA and / or possible spare parts mET for the internal combustion engine drive system 10.

[0060] In detail, the internal combustion engine drive system 10 has a mixture preparer 11 (especially a carburetor 12) and / or a spark plug 13 and / or a valve 14 (especially a fuel input valve 15) and / or a clutch 16.

[0061] Furthermore, the method includes the following steps: in particular, using a detection device 3 to detect the type TW of tool 2. The method also includes: in particular, using a determining device 4 to determine, based on the detected type TW, the set of possible fault symptoms mFS and / or possible fault causes mFU and / or possible maintenance instructions mRA and / or possible spare parts mET.

[0062] In detail, the discovery of the type TW of tool 2 involves: selecting the type TW of tool 2 from a large number of different motor-driven types TW and TW'.

[0063] In the illustrated embodiment, the user selects the type TW of tool 2, particularly by operating an input device 6 in the form of a touchscreen on a particular mobile device 30 of particular system 1, such as... Figure 1 and 7 As shown in the image.

[0064] In alternative embodiments, the detection device and tool (especially operating condition memory) may be configured to transmit, in particular wirelessly, an identifier (especially a serial number) for detecting the type of tool. Additionally or alternatively, in alternative embodiments, the system (especially the detection device) may include a camera, wherein the camera may be configured to capture images of the tool for detecting the type of tool, in particular, to capture images.

[0065] Additionally, the user can select the set of possible fault symptoms mFS. The method comprises the following steps: d) selecting fault symptoms aFS from the set of possible fault symptoms mFS that can be selected by the user, particularly by means of the detection device 3; e) determining, particularly by means of the determination device 4, a set of possible causes of failure mFU for tool 2 and / or possible maintenance instructions mRA and / or possible spare parts mET for tool 2 based on the selected fault symptoms aFS; f) outputting, particularly by means of the output device 5, the determined set of possible causes of failure mFU and / or possible maintenance instructions mRA and / or possible spare parts mET.

[0066] In the illustrated embodiment, the user selects the fault symptom aFS, in particular, by manipulating the input device 6, such as Figure 1 and 7 As shown in the image.

[0067] In addition, the operating edge conditions RB have the meteorological characteristic parameters MP of the operating environment 100 of tool 2, especially air pressure LD, air humidity LF, precipitation NI and / or temperature TE, and / or altitude HE and / or location PO, such as Figure 1 and 7 As shown in the image.

[0068] In detail, step a) includes: determining the altitude HE and / or position PO of the operating environment 100 of the detection tool 2, and in particular, determining the meteorological characteristic parameter MP based on the detected altitude HE and / or detected position PO by means of the detection device 3.

[0069] In the illustrated embodiment, the detection device 3 has an altitude measuring instrument for detecting altitude HE and / or a location determining device, particularly a satellite-positioning receiver, for detecting location PO.

[0070] In an alternative embodiment, the detection device may include a barometer for detecting air pressure, a humidity meter for detecting air humidity, a precipitation meter for detecting precipitation, and / or a thermometer for detecting temperature.

[0071] Furthermore, in the illustrated embodiment, the detection device 3 is configured to receive operating edge conditions RB, particularly meteorological characteristic parameters MP, based on the detected altitude HE and / or the detected location PO (especially wirelessly).

[0072] exist Figure 1 In the middle, the altitude HE is relatively high and therefore the air pressure LD is relatively low. Therefore, as a set of possible fault symptoms, mFS determines and outputs "tool begins to deteriorate or does not deteriorate" and / or as a set of possible fault causes determines and outputs "mixture preparer (especially carburetor) and / or spark plug failure" and / or as a set of possible maintenance instructions determines and outputs "maintain mixture preparer (especially carburetor) and / or spark plug" and / or as a set of possible spare parts determines and outputs "mixture preparer (especially carburetor) and / or spark plug".

[0073] In another scenario, if the altitude is relatively low and therefore the air pressure is relatively high, then "tool stalls after startup or while idling" is identified and output as a set of possible fault symptoms and / or "valve malfunction" is identified and output as a set of possible fault causes and / or "valve repair" is identified and output as a set of possible maintenance instructions and / or "valve" is identified and output as a set of possible spare parts.

[0074] exist Figure 5In the operating-speed-frequency distribution nHV, there is a relatively low frequency nLB in the no-load-speed range, a relatively high frequency nKB in the clutch-speed range, and a relatively low frequency nAB in the working-speed range. Therefore, "Tool started, but not working" is identified and output as a set of possible fault symptoms and / or "Clutch failure" is identified and output as a set of possible fault causes and / or "Clutch repair" is identified and output as a set of possible maintenance instructions and / or "Clutch" is identified and output as a set of possible spare parts.

[0075] exist Figure 7 In this context, location PO is an orange orchard. Therefore, the possible or potential material of the workpiece to be processed using tool 2 is very hard wood, especially different from the material in a vineyard. Therefore, as a set of possible fault symptoms, "the pruning shears blades no longer fully open or close" is identified and output; and / or as a set of possible fault causes, "fault in the transmission mechanism, especially the ball screw, ball nut, and / or pinion gear set" is identified and output; and / or as a set of possible maintenance instructions, "maintain the transmission mechanism, especially the ball screw, ball nut, and / or pinion gear set" is identified and output; and / or as a set of possible spare parts, "the transmission mechanism, especially the ball screw, ball nut, and / or pinion gear set" is identified and output.

[0076] In other words, the operating edge conditions may include possible or potential materials of a workpiece to be processed by a tool. In particular, step a) may include: determining the height and / or position of the tool's operating environment, and determining the material based on the determined height and / or position.

[0077] Furthermore, the determination involves selecting a set of possible fault symptoms mFS from a large number of different fault symptoms FS, FS', FS”, FS”', wherein, in particular, the determining device 4 is used to associate the fault symptoms FS, FS', FS”, FS”' with at least one operating edge condition RB, RB' from a large number of different operating edge conditions RB, RB' and / or at least one operating condition BB, BB' from a large number of different operating conditions BB, BB', especially with at least one type TW, TW' of tool 2 from a large number of different types TW, TW', such as Figure 3 and 6 As shown.

[0078] Additionally, the determination includes: selecting a set of possible fault causes mFU and / or possible maintenance instructions mRA and / or possible spare parts mET from a large number of different fault causes FU, FU', FU”, FU”' and / or different maintenance instructions RA, RA', RA”, RA”' and / or different spare parts ET, ET', ET”, ET”', wherein, in particular by means of the determining device 4, the fault causes FU, FU', FU”, FU”' and / or the maintenance instructions RA, RA', RA”, RA”' and / or the spare parts ET, ET', ET”, ET”' are correspondingly associated with at least one operating edge condition RB, RB' from a large number of different operating edge conditions RB, RB' and / or at least one operating condition BB, BB' from a large number of different operating conditions BB, BB' and / or at least one fault symptom FS, FS' from a large number of different fault symptoms FS, FS', in particular and at least one type TW, TW' of tool 2 from a large number of different types TW, TW' of tool 2.

[0079] Furthermore, the method includes the following steps: detecting the actual fault symptoms tFS and / or the actual fault cause tFU and / or the actual maintenance instructions tRA for tool 2 and / or the actual spare parts tET, such as Figure 4 As shown in the figure. In order to carry out the method thereafter, especially by means of the determining device 4, at least one operating edge condition RB is associated with the detected actual fault symptom tFS, and / or at least one operating edge condition RB and / or (especially selected and / or actual) fault symptom aFS, tFS are associated with the detected actual fault cause tFU and / or the detected actual maintenance instruction tRA and / or the detected actual spare part tET.

[0080] In the illustrated embodiment, the repairman, in particular by operating a touchscreen or other input device 6 of the system 1 of the fixed device 35, identifies or modifies the actual symptom of the tool 2 tFS and / or the actual cause of the malfunction tFU and / or the actual repair instructions tRA and / or the actual spare parts tET.

[0081] As shown and the embodiments described above clearly demonstrate, the present invention provides an advantageous method and an advantageous system for automatic assistance in the maintenance of motor-driven tools.
