The forklifts 10a to 10f are basically the same components, although there are differences in size, components, and the like. In the following description, the forklifts 10a to 10f are simply referred to as the forklift 10 when it is not necessary to distinguish them.

  FIG. 2 is a schematic diagram illustrating a schematic configuration of the forklift. Hereinafter, a schematic configuration of the forklift will be described with reference to FIG. As shown in FIG. 2, the forklift 10 includes two front wheels 12, two rear wheels 13, a mast 14, a fork 15, a tilt cylinder 16, a lift cylinder 17, a drive source 21, and a pump 22.

When the control device 35 acquires the operation data detected by the detection unit 29, the control device 35 transmits the operation data from the communication unit 28 to the relay devices 118a, 118b, and 118c.

  The control device 35 executes various controls based on operations input to the touch panel 32 (or input unit) by the operator. In addition, the control device 35 acquires information (failure information, information on various driving conditions) and the like input to the touch panel 32 (or input unit) by the operator as operation data, and communicates with the operation data detected by the detection unit 29. The data is transmitted from the unit 28 to the relay devices 118a, 118b, and 118c.

  Returning to FIG. 1, the description of the industrial vehicle management system 100 will be continued.

That is, the relay devices 118a, 118b, and 118c are provided in the user facilities 110a, 110b, and 110c where the forklifts 10 are used, and the control devices used in the user facilities 110a, 110b, and 110c. When the data transmitted from 35 is received, the data is transmitted to the server 130 via the communication line 116. The relay devices 118a, 118b, and 118c may temporarily store the data transmitted from the control device 35 and transmit the stored data to the server 130 at predetermined time intervals. Further, the relay devices 118a, 118b, and 118c may transmit the data of the control device 35 to the user terminals 120a, 120b, and 120c in parallel.

  The user terminals 120a, 120b, and 120c are arranged for each user facility 110a, 110b, and 110c.

The user terminals 120a, 120b, and 120c acquire information for managing the forklift 10 by transmitting and receiving information to and from each terminal such as the server 130 via the communication line 116. In addition, the user terminals 120 a, 120 b, and 120 c can transmit the operation data of the forklift 10 input by the user to the server 130. Here, the user terminals 120a, 120b, and 120c can communicate with the relay apparatuses 118a and 118c via the communication line 116 as in the user terminals 120a and 120c. Alternatively, it may be configured to be able to communicate directly with the relay device 118b. Note that the relay device 118b and the user terminal 120b transmit the operation data of the forklifts 10d and 10e acquired by the relay device 118b to the communication line 116 via the user terminal 120b. The user facilities 110a, 110b, and 110c are configured as described above.

  Next, the manager facility 112 is a facility that serves as a host for providing the service of the industrial vehicle management system 100 to the user of the forklift 10. The administrator facility 112 includes a server 130 and an administrator terminal 132, and collects and manages information on the forklifts 10 constituting the industrial vehicle management system 100. Here, FIG. 3 is a block diagram showing a schematic configuration of the server and the administrator terminal.

  The server (industrial vehicle management apparatus) 130 includes a control unit 160, a storage unit 162, and a communication unit 164. The control unit 160 is configured by a CPU or the like and executes various arithmetic processes. The storage unit 162 is a ROM, a RAM, or the like, and stores operation data, service data, a result calculated by the control unit 160, and the like supplied to the server 130. The communication unit 164 is connected to the communication line 116 and is a device that performs wireless communication by transmitting and receiving signals to and from the device connected via the communication line 116. The communication unit 164 transmits and receives various data based on the control of the control unit 160. In addition, the communication unit 164 is connected to the administrator terminal 132 in a communicable state.

  The server 130 is configured as described above, and manages each forklift 10. Specifically, the server 130 acquires various data including operation data of the forklift 10 through communication via the communication unit 164 and the communication line 116. Further, the server 130 receives service data including maintenance costs from the service person terminal 140. The server 130 detects the state of the forklift 10 by analyzing the acquired data and service data, and manages the forklift 10 based on the detection result. The control for managing the forklift 10 by the server 130 will be described later.

  The administrator terminal 132 is an information terminal such as a so-called personal computer, and includes a control unit 170, a storage unit 172, a communication unit 174, a display unit 176, and an operation unit 178. The control unit 170 is composed of a CPU or the like and executes various arithmetic processes. The storage unit 172 is a ROM, a RAM, or the like, and stores management data and analysis results of the forklift 10 supplied from the server 130, results calculated by the control unit 170, and the like. The communication unit 174 is connected to the communication line 116 and is a device that performs wireless communication by transmitting and receiving signals to and from the device connected through the communication line 116 via the communication line 116. The communication unit 174 transmits and receives various data based on the control of the control unit 170. In addition, the communication unit 174 is connected to the communication unit 164 of the server 130 in a communicable state. The display unit 176 is a device that displays an image, such as a liquid crystal display device. The display unit 176 displays an operation screen for operating the server 130, a screen (management screen) indicating the result calculated by the server 130, and the like based on the control of the control unit 170. The operation unit 178 is an input device through which an administrator inputs an operation. As an input device, various mechanisms such as a keyboard, a mouse, and a touch pad can be used.

  Next, the service facility 114 is a facility that performs maintenance, that is, maintenance and repair of the forklift 10. The service facility 114 replaces parts as necessary when the service person performs maintenance of the forklift 10. The service facility 114 includes a service person terminal 140. Similarly to the administrator terminal 132, the service person terminal 140 is an information terminal such as a so-called personal computer. The service person terminal 140 receives service data that is information of a service executed on the forklift 10 by the service person. The service person terminal 140 is connected to the server 130 via the communication line 116 and transmits the input service data to the server 130. Here, the service data is various information related to maintenance of the forklift 10, that is, maintenance and repair, such as the date and time when the maintenance and repair are performed, the cost of maintenance and repair, and the like. The service person may input and transmit service data every time maintenance of the forklift 10 is performed, or may input and transmit service data collectively. In addition, the service person terminal 140 can also receive information on the management result of the forklift 10 from the server 130.

  Next, the operation of the industrial vehicle management system 100 will be described with reference to FIGS. FIG. 4 is a flowchart showing an example of the processing operation of the forklift. First, the forklift processing operation will be described with reference to FIG. Further, the process shown in FIG. 4 can be executed by the control device 35. When the drive source 21 is started, that is, started, the control device 35 executes the process shown in FIG.

  The control apparatus 35 acquires operation data as step S12. That is, the control device 35 acquires various operation data detected by the detection unit 29 provided in the forklift 10. For example, the control device 35 uses the operating time of the forklift 10 measured by the operating time measuring unit of the detecting unit 29, the working time of the forklift 10 measured by the working time measuring unit, and the forklift measured by the loading time measuring unit. The loading time during which the vehicle 10 is loaded and operated and the travel distance of the forklift 10 measured by the travel distance measuring unit are acquired as operation data.

  After acquiring the operation data in step S12, the control device 35 accumulates the operation data as step S14. That is, the control device 35 temporarily accumulates the operation data acquired in step S12. After accumulating the operation data in step S14, the control device 35 determines whether there is an operation data transmission instruction in step S16. The transmission instruction may be an instruction transmitted from the server 130 or an instruction calculated by the control device 35 based on the control condition, and is input to the user terminals 120a, 120b, and 120c by the user and transmitted to the control device 35. You can also give instructions.

  If it is determined in step S16 that there is a transmission instruction (Yes), the control device 35 outputs the accumulated operation data to the server as step S18. That is, the control device 35 transmits the operation data to the corresponding relay devices 118a, 118b, and 118c. When receiving data from the control device 35, the relay devices 118a, 118b, and 118c store the data and transmit the data to the server 130 at predetermined time intervals. When the server 130 receives the output operation data, the server 130 stores it in the storage unit 162.

  After outputting the operation data to the server 130 in step S18, the control device 35 proceeds to step S20. If the control device 35 determines in step S16 that there is no transmission instruction (No), the control device 35 proceeds to step S20. When it is determined No in step S16 or when the process of step S18 is executed, the control device 35 determines whether the process is completed as step S20. If it is determined in step S20 that the process has not ended (No), the control device 35 proceeds to step S12 and executes the process of step S12 again. If the control device 35 determines in step S20 that the processing is complete (Yes), the control device 35 ends this processing.

  The forklift 10 acquires, accumulates, and outputs the operation data to the server 130 as described above. Further, the control device 35 repeats the processing from step S12 to step S20 until it is determined that the processing is finished, for example, while the forklift 10 is driven, that is, until it is stopped.

  FIG. 5 is a flowchart illustrating an example of the processing operation of the service provider terminal. The processing operation of the service provider terminal 140 will be described with reference to FIG. In step S30, the service provider terminal 140 determines whether service data has been updated. Here, when new service data, that is, processing executed on the forklift 10 (inspection, replacement of parts) is input and the input is confirmed by the service operator terminal 140, for example, data storage processing is executed. If it is, it is determined that the service data has been updated. If it is determined in step S30 that the service data has been updated (Yes), the service provider terminal 140 outputs the updated service data to the server in step S32. That is, the service person terminal 140 transmits the updated service data to the server 130 via the communication line 116. After performing the process of step S32, the service provider terminal 140 proceeds to step S34.

  When it is determined No in step S30, or when the process of step S32 is executed, the service provider terminal 140 determines whether the process ends as step S34. If it is determined in step S34 that the process is not finished (No), the service provider terminal 140 proceeds to step S30 and executes the process of step S30 again. If the service provider terminal 140 determines in step S34 that the process has ended (Yes), the service terminal 140 ends this process.

  The service person terminal 140 outputs the service data to the server 130 as described above. Further, the service provider terminal 140 repeats the processing from step S30 to step S34 until it determines that the processing is finished.

  As described above, the industrial vehicle management system 100 can accumulate the operation data and service data in the server 130, thereby collecting the information on the forklift 10 in the server 130, and can suitably manage the forklift 10. .

  The control executed when the user determines that a failure has occurred in the forklift 10 and notifies the administrator that the failure has occurred will be described with reference to FIGS. FIG. 6 is an explanatory diagram illustrating an example of a touch panel screen. FIG. 7 is a flowchart showing an example of the processing operation of the forklift. FIG. 8 is an explanatory diagram illustrating an example of a touch panel screen. The process shown in FIG. 7 is executed by the control device 35 of the forklift 10.

  First, the control device 35 displays a failure button 60 on a part of the screen 50 of the touch panel 32 as shown in FIG. The control device 35 of the present embodiment maintains a state in which the failure button 60 is displayed on a part of the screen 50 while the forklift 10 is operating, specifically, while the touch panel 32 is displaying an image. . Here, in the screen 50 of FIG. 6, the display of images other than the failure button 60 is omitted, but an image for an operation screen necessary for the operation of the forklift 10 and information for grasping the operation state of the forklift 10. May be displayed.

  Next, the control of the control device 35 will be described with reference to FIG. The control device 35 determines whether or not there is a touch on the failure button in step S40. That is, the control device 35 determines whether an operation on the failure button 60 displayed on the screen 50 is detected by the touch panel 32.

  If the control device 35 determines in step S40 that there is no touch on the failure button (No), the control device 35 proceeds to step S40. The control device 35 repeats the process of step S40 until it detects a touch on the failure button. When it is determined in step S40 that the failure button is touched (Yes), the control device 35 displays a failure item selection screen as step S42. The control device 35 displays a failure item selection screen 52 on the touch panel 32 as shown in FIG. The failure item selection screen 52 includes six item buttons 62a, 62b, 62c, 62d, 62e, and 62f, and a transmission button 64. The six item buttons 62a, 62b, 62c, 62d, 62e, and 62f are buttons that are operated when a failure item is designated, and are associated with different failure items. The item button 62a is associated with an engine. The item button 62b is associated with a mast. The item button 62c is associated with a front axle. The item button 62d is associated with a transmission. The item button 62e is associated with hydraulic pressure. The item button 62f is associated with a rear axle. The six item buttons 62a, 62b, 62c, 62d, 62e, and 62f display words indicating the corresponding items. In this embodiment, since the item button 62e is selected, it is displayed in a different display mode (a mode in which at least one of color and shape is different) from the other item buttons 62a, 62b, 62c, 62d, and 62f. ing. The control device 35 makes it easy to visually recognize the selected item by changing the display depending on whether or not the item is selected.

  When the failure item selection screen 52 is displayed in step S42, the control device 35 determines whether there is a touch on the item button in step S44. That is, the control device 35 determines whether an operation on any of the six item buttons 62a, 62b, 62c, 62d, 62e, and 62f displayed on the screen 50 is detected by the touch panel 32.

  If the control device 35 determines in step S44 that there is no touch on the item button (No), the control device 35 proceeds to step S48. When it is determined in step S44 that the item button is touched (Yes), the control device 35 switches the selection state of the touched item button in step S46. For example, when the item button 62a on the failure item selection screen 52 in FIG. 8 is touched, the item button 62a is switched to the selected state, and the display mode of the item button 62a is set to the same display mode as the item button 62e. When the item button 62e on the failure item selection screen 52 in FIG. 8 is touched, the item button 62e is switched to the unselected state, and the display mode of the item button 62e is changed to the other item buttons 62a, 62b, 62c, 62d, 62f. And the same display mode. After switching the display mode, the control device 35 proceeds to step S48.

  When it determines with No at step S44, or when the process of step S46 is performed, the control apparatus 35 determines whether there exists a touch to a transmission button as step S48. When it is determined in step S48 that the transmission button is not touched (No), the control device 35 proceeds to step S44, and executes the processing from step S44 to step S48 again.

  When it is determined in step S48 that the transmission button is touched (Yes), the control device 35 transmits the failure information to the server as step S50. Here, the failure information includes information indicating that a failure has occurred and information on an item selected on the failure item selection screen 52. Further, the control device 35 can include information such as a user name, a vehicle name, a vehicle type, a delivery date, an operation time, a travel distance, and a loading time of the forklift in which the failure has occurred in the failure information. Further, the control device 35 may include information such as the contact information of the user and the name of the person in charge in the failure information depending on the setting. Further, the control device 35 may add identification information to the failure information, and some information may be combined with information stored in the storage unit 162 on the server 130 side. The control apparatus 35 will complete | finish this process, if failure information is transmitted to a server by step S50.

  As described above, the forklift 10 can transmit, to the server, information indicating that a failure has occurred, and further, the failure position specified by the user, based on the user's operation on the touch panel.

  FIG. 9 is a flowchart illustrating an example of the processing operation of the server. Next, failure information reception processing executed by the server 130 will be described with reference to FIG. The process shown in FIG. 9 is executed by the control unit 160 of the server 130. The control part 160 acquires failure information as step S60. That is, failure information output from the forklift 10 toward the server 130 is acquired. When the failure information is acquired in step S60, the control unit 160 outputs the failure information to the corresponding terminal as step S62. Here, the corresponding terminal is each terminal corresponding to the failure of the forklift 10 that has output the failure information. In the present embodiment, an administrator terminal 132 used by an administrator who manages the industrial vehicle management system 100, a service person terminal 140 used by a service person who performs maintenance in response to a failure of the forklift 10, and the forklift 10 are installed. The data is output to any one of the user terminals 120a, 120b, and 120c corresponding to the user facilities 110a, 110b, and 110c. When the failure information is output to the corresponding terminal in step S62, the control unit 160 accumulates the failure information in step S64. That is, the control unit 160 stores the failure information in the storage unit 162 and ends the process. The control unit 160 stores the failure information and the forklift in association with each other. Thereafter, when service data (replenishment / repair data) corresponding to the failure information is acquired, the control unit 160 further stores the service data in association with the failure information.

  Thus, the industrial vehicle management system 100 can output failure information to the server 130 only by operating the touch panel 32. Furthermore, the industrial vehicle management system 100 transmits failure information from the server 130 to each related terminal. Accordingly, the user can supply necessary failure information to the server 130 only by operating the touch panel 32, and further transfers the information to each unit via the server 130. For this reason, since the user can notify the occurrence of a failure without searching for a telephone destination, the burden on the user can be reduced. Moreover, since the industrial vehicle management system 100 determines a failure based on a user's determination, it is possible to appropriately detect a failure of the forklift 10.

  Moreover, the industrial vehicle management system 100 can suppress the failure information corresponding to the manager and the servicer being sent more than necessary by sending the failure information to the server 130 using the operation on the touch panel 32 as a trigger. . In other words, when the allowable conditions are exceeded, the failure information is automatically sent to the server 130 as the failure condition, so that even if a simple failure that can be handled by the user or no actual failure occurs, Confirmation is required. On the other hand, the industrial vehicle management system 100 can set the failure information as information that the user recognizes as a failure and cannot be solved by triggering an operation on the touch panel 32. Thereby, the administrator and the service person can efficiently acquire failure information that needs to be dealt with, and can perform maintenance efficiently.

  The industrial vehicle management system 100 includes information on the failure position specified by the user (information on the selected item button) in the failure information, so that the administrator and the service person quickly understand the information on the specified failure position. can do. In addition, by using the industrial vehicle management system 100, the manager and the service person can contact the user and hear the information in a state where the failure part is understood. Thereby, maintenance can be started after grasping the state of the forklift. For example, the necessary tools and parts can be grasped first, so it is possible to create a maintenance plan based on the failure information first without having to grasp the state of the forklift and then create a maintenance plan to perform actual maintenance. Therefore, it is possible to confirm the state of the forklift and perform maintenance as it is. In addition, in the industrial vehicle management system 100, operation data and service data are accumulated and scattered in the server 130 in addition to failure data. Thereby, the administrator and the service person can grasp the state of the forklift with higher accuracy by the information supplied via the server 130.

  Here, the industrial vehicle management system 100 operates the touch panel 32 provided on the forklift 10 to output the failure information, but is not limited thereto. The industrial vehicle management system 100 may send failure information from the user terminals 120a, 120b, and 120c to the server 130.

  FIG.10 and FIG.11 is explanatory drawing which shows an example of the screen of a user terminal. The user terminals 120a, 120b, 120c display a screen 70 as shown in FIG. The screen 70 includes a table 72 of basic data of the forklift 10 arranged in the corresponding user facilities 110a, 110b, 110c. Further, the screen 70 displays a failure button 60 at a position corresponding to each forklift 10 in Table 72. One failure button 60 is associated with one forklift 10.

  When any of the failure buttons 60 is pressed or clicked by the user, the user terminals 120a, 120b, and 120c are displayed on the failure item selection screen 76 shown in FIG. 11 corresponding to the forklift 10 associated with the failure button 60. Is displayed. The failure item selection screen 76 has basically the same configuration as the failure item selection screen 52 shown in FIG. 8 except that the display positions are the user terminals 120a, 120b, and 120c. The failure item selection screen 76 has six item buttons 62 a, 62 b, 62 c, 62 d, 62 e, 62 f and a send button 64. The six item buttons 62a, 62b, 62c, 62d, 62e, and 62f are buttons that are operated when a failure item is designated, and are associated with different failure items. The item button 62a is associated with an engine. The item button 62b is associated with a mast. The item button 62c is associated with a front axle. The item button 62d is associated with a transmission. The item button 62e is associated with hydraulic pressure. The item button 62f is associated with a rear axle. The six item buttons 62a, 62b, 62c, 62d, 62e, and 62f display words indicating the corresponding items.

  The user terminals 120a, 120b, and 120c switch between selection and non-selection when an operation is input to the six item buttons 62a, 62b, 62c, 62d, 62e, and 62f on the failure item selection screen 76. In addition, when the transmission button 64 is operated, the user terminals 120a, 120b, and 120c select an item that is selected when the transmission button 64 is operated among the six item buttons 62a, 62b, 62c, 62d, 62e, and 62f. The failure information including the information indicating the failed portion is output to the server 130.

  The industrial vehicle management system 100 can output the failure information from the user terminals 120a, 120b, and 120c, and can output the failure information to the server even when the touch panel 32 of the forklift 10 cannot be used due to the failure. . In addition, the industrial vehicle management system 100 can output failure information from the user terminals 120a, 120b, and 120c, and can collectively manage failure information of a plurality of forklifts 10 that it owns.

  Next, control of the administrator terminal that has received the failure information will be described. In addition, although this embodiment demonstrates as control of the administrator terminal 132, the same process can be performed also in another terminal. 12 to 16 are explanatory diagrams illustrating examples of screens displayed on the display unit of the administrator terminal. When the failure information is sent from the server 130 to the administrator terminal 132, in addition to the customer information and occurrence information (occurrence time, occurrence location), the forklift 10 associated with the failure information and the user are the same, that is, the same use The usage information of the forklift 10 arranged in the person's facility is displayed. The administrator terminal 132 causes the display unit 176 to display the screen 80 shown in FIG. The screen 80 is a table of operation data and analysis results of forklifts with the same user. The screen 80 includes a vehicle body number, a model, an operation mode, an annual accumulated time, an annual travel distance, and a root-to-root operating rate (annual operating time). Here, in the present embodiment, the operation mode is classified into four. When there is a lot of cargo handling, it becomes “loading type”, when the traveling distance is long, it becomes “traveling type”, when both are many, it becomes “high operating type”, and when both are few, it becomes “low operating type”. The administrator terminal 132 can make it easy to estimate the failure location by displaying the operation mode of the forklift on the screen 80.

  Further, the administrator terminal 132 causes the display unit 176 to display the screen 82 shown in FIG. The screen 82 displays the maintenance history (maintenance execution time and contents) of the forklift 10 to which the failure information has been transmitted, the failure history (failure time, failure location), replacement parts information (replacement parts and replacement time), etc. It is a table | surface in which the maintenance history of the forklift 10 is contained. By displaying the screen 82, the administrator terminal 132 can grasp the maintenance history of the forklift 10, and makes it easy to estimate the failure location from parts that have not been replaced for a long period of time or parts that have many failures. be able to.

  The administrator terminal 132 displays the operation mode of the vehicle and the maintenance history (history related to maintenance) together with the failure information on the screen so that it can be referred to, thereby facilitating the estimation of the cause of the failure so that a quick response can be made. To.

  Next, when failure information is sent from the server 130, the administrator terminal 132 may cause the display unit 176 to display a screen 84 and a screen 86 in addition to the various screens described above, as shown in FIG. . The screen 84 is a table showing usage information of the target forklift. The screen 86 is a list of parts constituting the engine (drive source 21). The screen 86 includes the part number, part name, price, inventory, delivery date, etc. of each part.

  The administrator terminal 132 displays the device number of the device (drive source, transmission, hydraulic system, etc.) used for the model in which the failure has occurred on the screen 84, thereby making it easier to plan the maintenance of the failed part. be able to. Further, the manager terminal 132 allows the screen 86 to refer to the parts list used in the apparatus, the inventory quantity of each part, and the delivery date. Thereby, parts required for repair can be specified at an early stage. In addition, by making it possible to check the inventory and delivery date of the necessary parts, quick repairs can be made.

  Next, when failure information is sent from the server 130, the administrator terminal 132 may provide a part drawing button 89 at a position corresponding to each part on the screen 86 as shown in the window 88 of FIG. The administrator terminal 132 includes drawing data of each part, and when the part drawing button 89 is operated, the part drawing 90 corresponding to the part drawing button 89 is displayed as shown in FIG.

  In this way, the administrator terminal 132 displays the device number of the device (drive source 21, transmission, hydraulic system, etc.) used in the model in which the failure has occurred and a list of parts used in the device. It is preferable that a link with a component diagram is attached to the system so that the shape of the component can be confirmed. In FIGS. 15 and 16, component drawings are used, but a drawing without assembly can be similarly provided with a link. Thus, it is possible to quickly cope with a failure by checking the shape of the component.

  Here, the forklift 10 is often operated in a state in which various designs are changed according to the user's request according to the purpose of use. For this reason, the structure of the mechanism and components currently used is diverse, and it is difficult to grasp. Therefore, as described above, for each target forklift, by displaying the type of drive source, transmission and hydraulic system used, and the shape, model, price, etc. of the components constituting them, the model is mistaken. It can suppress that the situation which cannot be repaired generate | occur | produces.

  Although the industrial vehicle management system 100 of the said embodiment demonstrated the process performed when failure information was output from the user, the utilization method of failure information is not limited to this. The industrial vehicle management system 100 preferably controls abnormality information using failure information, driving data, and service data. Here, the abnormality information is information output by detecting a state (abnormal state) in which the forklift 10 is operating under an operating condition exceeding an allowable value. In addition, abnormal information may be output due to a failure, but basically it is detected and output when operating under a non-recommended operating condition because it is operable but may lead to failure. Is done.

  Hereinafter, the operation of each unit will be described with reference to FIGS. FIG. 17 is a flowchart illustrating an example of the processing operation of the forklift. The control device 35 of the forklift 10 acquires operation data as step S70, and analyzes the operation data acquired as step S72. That is, the control device 35 analyzes the acquired operation data and detects the operation state.

  After analyzing the operation data in step S72, the control device 35 determines whether there is an abnormality in step S74. That is, it is determined whether or not the vehicle is operating in an abnormal state. When determining that there is an abnormality (Yes) in Step S74, the control device 35 outputs abnormality information to the touch panel and the server as Step S76. Accordingly, it is possible to notify that the operation is being performed in a state not recommended to the user who is operating and operating the forklift 10. The method for notifying abnormality information is not limited to the output to the touch panel 32. For example, the abnormality information may be output by a buzzer or a voice message. Moreover, the control apparatus 35 may notify the driving | operation which can eliminate an abnormal state, for example, deceleration, temporary suspension of work, etc.

  When it is determined that there is no abnormality (No) in Step S74, or when the process of Step S76 is performed, the control device 35 determines whether the process is completed as Step S78. If it is determined in step S78 that the process has not ended (No), the control device 35 proceeds to step S70 and executes the above process again. If the control device 35 determines in step S78 that the process is complete (Yes), it ends this process.

  Thus, the forklift 10 can request the user to refrain from driving under unreasonable conditions by outputting abnormality information when an abnormal state is detected. In addition, by sending abnormal information indicating that an abnormal state has been detected to the server 130, it is possible to more accurately grasp the user's driving that may lead to a failure.

  Next, FIG. 18 is a flowchart illustrating an example of the processing operation of the server. The processing operation of the server 130 using the abnormality information will be described using FIG. Further, the process shown in FIG. 18 can be executed by the control unit 160 of the server 130.

  In step S80, the control unit 160 specifies the forklift to be analyzed. That is, the control unit 160 specifies a forklift to be analyzed from the forklift included in the industrial vehicle management system 100. After identifying the forklift in step S80, the control unit 160 extracts operation data, service data, and abnormality information from the storage unit 162 in step S82. That is, the control unit 160 reads the identified forklift operation data, service data, and abnormality information from the storage unit 162.

  After reading the data in step S82, the control unit 160 determines whether or not it is necessary to acquire the latest data in step S84. The control unit 160 determines whether it is necessary to acquire the latest data based on the information and settings stored in the storage unit 162. When it is determined in step S84 that the latest data needs to be acquired (Yes), the control unit 160 acquires the latest operation data, service data, and abnormality information as step S86. The control unit 160 communicates with the forklift 10 to acquire the latest operation data and abnormality information, and communicates with the service person terminal 140 to acquire the latest service data.

  When the latest data is acquired in step S86, or when it is determined in step S84 that acquisition of the latest data is not necessary (No), the control unit 160 analyzes the state of the forklift as step S88, and step S90. To determine whether the failure occurrence probability is equal to or greater than a threshold value. For example, the control unit 160 calculates, for each unit, a failure occurrence probability that increases due to operation in an abnormal state based on the history of operation data, service data, and abnormality information. Determine if there is. The threshold value of the failure occurrence probability will be described later.

  When it is determined in step S90 that the failure occurrence probability is equal to or higher than the threshold (Yes), the control unit 160 outputs failure caution information to the user terminal and the touch panel as step S92. Here, the failure attention information is information notifying that there is a high possibility that a failure will occur. When it is determined in step S90 that the failure occurrence probability is less than the threshold value (No), or when the process of step S92 is performed, the control unit 160 ends this process.

  As shown in FIG. 18, the industrial vehicle management system 100 calculates the failure occurrence probability with the server 100 and alerts the user based on the calculation result, thereby suppressing the occurrence of the failure. .

  Note that the control unit 160 may output failure attention information to the administrator terminal 132 and the service person terminal 140. Thereby, the administrator and the service person can grasp in advance the forklift 10 that is likely to cause a failure and the mechanisms and components that are likely to cause the failure. As a result, even if a failure occurs without performing maintenance, it is possible to respond quickly.

  The control unit 160 can sequentially analyze the forklifts included in the industrial vehicle management system 100 by sequentially switching the forklifts 10 to be analyzed and repeatedly executing the process of FIG. Thereby, the server 130 and the industrial vehicle management system 100 can acquire the analysis result which can manage suitably the forklift 10, and can manage suitably.

  FIG. 19 is a flowchart illustrating an example of processing operation of the server. Here, the process shown in FIG. 19 is an example of a threshold value determination method for determining the failure occurrence probability. In step S100, the control unit 160 extracts operation data, failure information, service data, and abnormality information from the storage unit 162. That is, the control unit 160 reads the identified forklift operation data, failure information, service data, and abnormality information from the storage unit 162. Here, in FIG. 19, it is preferable to extract not only data of one forklift 10 but also data of a plurality of forklifts 10.

  When the information is extracted in step S100, the control unit 160 compares the abnormality information history, the failure information, and the maintenance history in step S102. That is, the control unit 160 extracts the timing when the actual failure has occurred from the failure information, extracts the maintenance history of each unit from the service data, and matches it with the history of abnormality information, thereby increasing the possibility of the failure. Abnormal information conditions are calculated. After performing the comparison in step S102, the control unit 160 determines a failure occurrence probability threshold value in step S104, and ends this process.

  The industrial vehicle management system 100 uses the failure information in this manner to specify the timing at which the actual failure has occurred, thereby determining the failure occurrence probability threshold that can prevent the failure in advance with high accuracy. It can be corrected. Thereby, the probability that a failure will occur can be reduced. Further, by repeating the process shown in FIG. 19 and setting the threshold value in step S104 to a high accuracy, it is possible to use the parts of each part of the forklift 10 to a length closer to the life while suppressing the occurrence of failure. It becomes. This can extend the life of the device.

  The number of each part which comprises the industrial vehicle management system 100, user facility 110a, 110b, 110c, administrator facility 112, and service facility (maintenance facility) 114 is not specifically limited. For example, the number of user facilities 110a, 110b, 110c is not limited as long as it is one or more. Further, a plurality of manager facilities 112 and service facilities (maintenance facilities) 114 may be provided. Each user facility 110a, 110b, 110c may include a plurality of relay devices 118a, 118b, 118c and a plurality of user terminals 120a, 120b, 120c. Similarly, a plurality of servers 130, administrator terminals 132, and service person terminals 140 may be provided.

  In the industrial vehicle management system 100 of the above embodiment, the service facility 114 and the administrator facility 110 are separated, but may be integrated. That is, the management of the system and the maintenance of the forklift may be performed in one facility. In this case, the administrator terminal 132, the service person terminal 140, and one terminal may be used. Further, the administrator terminal 132 and the service person terminal 140 may be integrated with the server 130. In this case, the service data can be acquired without going through the communication unit. The method by which the server 130 acquires service data is not limited to communication via a communication line. The server 130 may acquire service data via a storage medium, or may acquire service data by input to an input device installed in the server 130.

  In the industrial vehicle management system 100 of the above embodiment, the server 130 temporarily stores the operation data in the storage unit 162, but the present invention is not limited to this. The server 130 may acquire all the operation data used for the analysis from the forklift or the user terminal without storing the operation data used for the analysis in the storage unit. In this case, it replaces with the process which reads driving | operation data from the memory | storage part of the said process, and becomes a process which acquires driving | running | working data via a communication part. The industrial vehicle management system 100 temporarily stores the operation data stored in the storage unit of the server and the operation data acquired by the communication unit through communication. The operation data acquired by the department is compared with the service data.

  In the said embodiment, although demonstrated as a case where a forklift was used as an industrial vehicle, it is not limited to this. As the industrial vehicle, a vehicle including a traveling unit and a working unit other than a forklift can be used. For example, an excavator, a dump truck, or a bulldozer can be used as the industrial vehicle. When a vehicle other than a forklift is used as an industrial vehicle, the cargo handling related maintenance cost in the above embodiment is a maintenance cost related to the working unit, and the loading time is a working time during which the working unit is performing work. Thereby, an industrial vehicle can be managed suitably.
