[0013] The threshold value may be a value based on the durability of a connection device that connects the user and the walking training device.

[0014] The state detection unit can detect the load state based on a change in the user's posture by using captured images of the user using the walking training device.

[0015] The state detection unit can detect the load state based on a change in the load of the user outputted by a load measuring device that measures the load of the user.

[0021] Hereinafter, a management system according to an embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a diagram showing a management system 1 according to an embodiment of the present invention. The management system 1 is a system for managing a walking training device 10. The management system 1 includes the walking training device 10, a management device 20, and a notification destination device 30. The walking training device 10, the management device 20, and the notification destination device 30 can perform data communication with each other via a network 40.

[0022] The walking training device 10 is a device for allowing a user to perform walking training. The walking training device 10 may be installed in places such as hospitals and rehabilitation facilities. The walking training device 10 provides log information relating to the walking training device 10 to the management device 20. Details of the walking training device 10 will be described with reference to Figs. 2 to 5.

[0023] The management device 20 is a device for managing the walking training device 10. The management device 20 may be installed at a manufacturer of the walking training device 10, etc. The management device 20 determines the timing of maintenance of the walking training device 10. When the timing of maintenance of the walking training device 10 arrives, the management device 20 transmits a notification to that effect to the notification destination device 30. Details of the management device 20 will be described with reference to FIG. 6.

[0024] The notification destination device 30 is a device that receives a notification from the management device 20 that it is time for maintenance of the walking training device 10. The notification destination device 30 may be installed in a company or the like that performs maintenance of the walking training device 10.

[0025] 2 is a perspective view showing a walking training device 10 according to one embodiment of the present invention. The walking training device 10 includes a main body 11, a control device 12 (not shown), a treadmill 13, a suspension load-relieving device 14, a camera unit 15, and a load measuring device 161 (not shown).

[0026] The main body 11 is a support structure for the walking training device 10. The control device 12 is a device that performs overall control of the walking training device 10. The treadmill 13 is a device on which the user walks, and includes a rotating member that rotates in accordance with the user's walking pace.

[0027] The suspension support device 14 is a support device for supporting a user from above via a connection device. The connection device includes an attachment and a belt. The attachment is attached to a body part of the user, such as the waist. One end of the belt is connected to the attachment, and the other end is connected to the suspension support device 14. The suspension support device 14 supports the user from above via the belt and attachment connected in this manner.

[0028] The camera unit 15 includes an image sensor for capturing an image of the user. The camera unit 15 is installed in a position where it can capture an image of the user who is using the walking training device .

[0029] 3 is a side view showing an example of a walking assist device 16 according to an embodiment of the present invention. The walking assist device 16 is a device that is attached to the legs of a user and assists the user in walking. The walking assist device 16 includes a bottom part 160. The user's feet are placed on the upper surface of the bottom part 160.

[0030] 4 is a perspective view showing the bottom 160 of the walking assist device 16. A load measuring device 161 is provided on the bottom 160. The load measuring device 161 is a device for measuring a load applied to the walking training device 10 by a user wearing the walking assist device 16 while using the walking training device 10. A specific example of the load measuring device 161 is a load sensor that detects a load applied vertically to the bottom 160.

[0031] 4, any number of load measuring devices 161 can be installed at any positions on the bottom 160. Also, a load measuring device 161 may be installed directly under the treadmill 13 to measure the load applied to the walking training device 10 by the user while using the walking training device 10.

[0032] 5 is a diagram showing the configuration of the walking training device 10. The walking training device 10 includes a control device 12, a load measuring device 161, and a motion information generating device 17.

[0033] The motion information generating device 17 is a device that acquires motion information indicating the motion of the user. A specific example of the motion information generating device 17 is an image sensor. The image sensor captures an image of the user using the walking training device 10, generates a captured image, and outputs the captured image. The captured image corresponds to motion information.

[0034] The control device 12 is a device that performs overall control of the walking training device 10. The control device 12 includes a processor 120, a communication interface (I / F) 130, and a storage device 140.

[0035] The communication interface 130 is a device that performs data communication between the control device 12 and other devices. The communication interface 130 can perform data communication with the load measuring device 161 and the motion information generating device 17. The communication interface 130 can also perform data communication with the management device 20 and the notification destination device 30 via the network 40. The storage device 140 is a device in which various information such as programs processed by the control device 12 is stored.

[0036] The processor 120 is a device that reads out and executes a program from the storage device 140. Specific examples of the processor 120 include a CPU (Central Processing Unit) and an MPU (Micro Processing Unit). The program executed by the processor 120 includes a state detection unit 121, an evaluation value calculation unit 122, and a log transmission unit 123. These programs may be executed by an integrated circuit such as an FPGA (Field-Programmable Gate Array) or an ASIC (Application Specific Integrated Circuit). The control device 12, the processor 120, and the integrated circuit correspond to a computer.

[0037] The state detection unit 121 is a program that detects a load state in which a user using the walking training device 10 may apply a load to the walking training device 10, using the motion information generated by the motion information generation device 17. This load state includes, for example, a fall of the user. Therefore, the state detection unit 121 can detect that a user using the walking training device 10 has fallen. The state detection unit 121, the processor 120 in which the state detection unit 121 is implemented, and the control device 12 correspond to the state detection unit. Furthermore, the processor 120 and the control device 12 correspond to a computer.

[0038] The state detection unit 121 can detect the load state based on a change in the user's posture by using a captured image of the user using the walking training device 10. For example, the state detection unit 121 can analyze the captured image of the user, and determine that the user has fallen if the posture of the user while walking changes to the posture of the user at the time of falling.

[0039] Furthermore, the state detection unit 121 can detect the load state based on a change in the user's load output by the load measuring device 161. For example, the state detection unit 121 can analyze the user's load output by the load measuring device 161, and determine that the user has fallen if the user's load decreases suddenly. More specifically, the state detection unit 121 can determine that the user has fallen if the decrease in the user's load per unit time exceeds a predetermined threshold. The predetermined threshold can be determined based on the decrease in load expected when the user falls.

[0040] Furthermore, the state detection unit can detect the load state based on the load applied by the user to the suspension support device 14. For example, the state detection unit 121 can analyze the load of the user measured by the suspension support device 14, and determine that the user has fallen if the load of the user increases suddenly. More specifically, if the increase in the load of the user per unit time exceeds a predetermined threshold, the state detection unit 121 can determine that the user has fallen. The predetermined threshold can be determined based on an increase in load expected when the user falls.

[0041] The evaluation value calculation unit 122 is a program that calculates an evaluation value for evaluating the load on the walking training device 10 by the user. In this embodiment, an integrated load based on the number of falls of the user and a predetermined load is adopted as the evaluation value. The evaluation value calculation unit 122, the processor 120 in which the evaluation value calculation unit 122 is implemented, and the control device 12 equipped with the processor 120 correspond to the evaluation value calculation unit.

[0042] It is preferable to adopt a default load that is equal to or greater than the load that the user can apply to a connection device (such as a belt or a brace) that connects the user to the walking training device 10. Specifically, the default load can be determined based on the weight of the user wearing the walking aid device 16. In the event of a fall, a load equal to or greater than the weight of the user wearing the walking aid device 16 is applied to the connection device. Therefore, it is preferable to adopt a load that is several times the weight of the user wearing the walking aid device 16. For example, if the weight of the user wearing the walking aid device 16 is 105 kg, a default load of about 4200 N, which is more than four times the weight of the user wearing the walking aid device 16, can be adopted. When the state detection unit 121 detects a fall of the user, the evaluation value calculation unit 122 accumulates the default load and calculates the accumulated load as the evaluation value.

[0043] The log transmission unit 123 is a program that transmits log information related to the walking training apparatus 10 to the management device 20. The log information includes identification information of the walking training apparatus 10 and the evaluation value calculated by the evaluation value calculation unit 122.

[0044] 6 is a diagram showing the configuration of the management device 20. The management device 20 includes a processor 21, a communication interface 22, and a storage device .

[0045] The communication interface 22 is a device that performs data communication between the management device 20 and other devices. The communication interface 22 can perform data communication with the walking training device 10 and the notification destination device 30 via the network 40.

[0046] The storage device 23 is a device that stores various information such as programs and data tables processed by the processor 21. Fig. 7 is a diagram showing an example of a data table stored in the storage device 23. Information related to the walking training device 10 included in the management system 1 is registered in the data table shown in Fig. 7.

[0047] Specifically, the data table registers the identification information of the walking training device 10, a threshold value assigned to the walking training device 10, and notification destination information. The threshold value is a value based on the durability of the connecting tool. The threshold value can be determined based on the degree of damage, deterioration, fraying, etc. obtained by a durability test of the connecting tool. For example, the threshold value can be several tens to several hundreds of times the above-mentioned predetermined load. The threshold value is used when determining the timing of maintenance of the walking training device 10.

[0048] The notification destination information is information that indicates the destination of a notification that the timing for maintenance of the walking training apparatus 10 has arrived. For example, the notification destination information may be the contact information of a business entity that performs maintenance of the walking training apparatus 10.

[0049] The processor 21 is a device that reads out and executes a program from the storage device 23. Specific examples of the processor 21 include various processors such as a CPU and an MPU. The programs executed by the processor 21 include a timing determination unit 210 and a notification unit 211. These programs may be executed by an integrated circuit such as an FPGA or an ASIC. The management device 20, the processor 21, and the integrated circuit correspond to a computer.

[0050] The timing determination unit 210 is a program that determines that the time for maintenance of the walking training device 10 has arrived when an evaluation value for evaluating the load on the walking training device 10 by the user is equal to or greater than a threshold value associated with the walking training device 10. In this embodiment, the timing determination unit 210 compares an accumulated load based on the number of falls of the user and a predetermined load with a threshold value associated with the walking training device 10, and determines that the time for maintenance of the walking training device 10 has arrived when the accumulated load is equal to or greater than the threshold value. The timing determination unit 210, the processor 21 in which the timing determination unit 210 is implemented, and the management device 20 including the processor 21 correspond to the timing determination unit.

[0051] The notification unit 211 is a program that notifies the notification destination device 30 that the timing for maintenance of the walking training device 10 has arrived.

[0052] 8 is a flowchart showing the process executed by the walking training device 10. The walking training device 10 can repeatedly execute the process of FIG.

[0053] In step S101, the motion information generating device 17 generates motion information of the user who is using the walking training device 10. In step S102, the state detecting unit 121 of the control device 12 uses the motion information generated by the motion information generating device 17 to determine whether or not a load state has been detected. If a load state has not been detected (NO), the process of FIG. 8 ends. On the other hand, if a load state is detected, If so (YES), the process branches to step S103. In step S103, the evaluation value calculation unit 122 of the control device 12 calculates the evaluation value, and the process of FIG.

[0054] 9 is a flowchart showing the processing executed by the management device 20. When the management device 20 receives the log information from the walking training device 10, it can execute the processing shown in FIG.

[0055] In step S201, the timing determination unit 210 of the management device 20 acquires from the storage device 23 a threshold value associated with the identification information of the walking training device 10 included in the received log information. In step S202, the timing determination unit 210 determines whether or not the evaluation value included in the received log information is equal to or greater than the acquired threshold value. If the evaluation value is less than the threshold value (NO), the process of FIG. 9 ends. On the other hand, if the evaluation value is equal to or greater than the threshold value (YES), in step S203 the notification unit 211 notifies the notification destination device 30 that the time for maintenance of the walking training device 10 that transmitted the log information has arrived, and the process of FIG. 9 ends.

[0056] In the above-described embodiment, the state detection unit 121 detects that the user has fallen while using the walking training device 10. Next, the evaluation value calculation unit 122 calculates an evaluation value for evaluating the load on the walking training device 10 by the user. Then, when the evaluation value is equal to or greater than a threshold value associated with the walking training device 10, the timing determination unit 210 determines that the time for maintenance of the walking training device 10 has arrived. In this way, the timing determination unit 210 can determine the timing for maintenance of the walking training device 10.

[0057] In the above-described embodiment, the state detection unit 121 detects that the user has fallen while using the walking training device 10. The evaluation value is an accumulated load based on the number of falls of the user and a predetermined load. This allows the timing determination unit 210 to determine that the timing for maintenance of the walking training device 10 has arrived, based on the number of falls of the user and the accumulated load based on the predetermined load.

[0058] Furthermore, the predetermined load is equal to or greater than the load that the user can apply to the connection tool that connects the user to the walking training apparatus 10. This allows the timing determination unit 210 to determine that the time for maintenance of the connection tool of the walking training apparatus 10 has arrived, based on the load that the user can apply to the connection tool.

[0059] Furthermore, the threshold value is a value based on the durability of the connected appliance, which allows the timing determination unit 210 to determine that the timing for maintenance of the connected appliance has arrived based on the durability of the connected appliance.

[0060] Furthermore, the state detection unit 121 can detect a fall of the user based on a change in the user's posture using a captured image of the user using the walking training device 10. This allows the state detection unit 121 to detect a fall of the user based on a change in the user's posture, and accurately detect that the user has fallen.

[0061] Furthermore, the state detection unit 121 can detect a fall of the user based on a change in the load of the user output by the load measuring device 161 that measures the load of the user. By using both this detection means and a means for detecting a fall of the user based on a captured image of the user while using the walking training device 10, the accuracy of detection of a fall of the user can be improved.

[0062] Furthermore, the state detection unit can detect a fall of the user based on the load applied to the suspension support device 14 that supports the user via the connection device attached to the user. This can improve the accuracy of detecting a fall of the user.

[0063] In another embodiment, the evaluation value may be an integrated load based on the number of falls of the user and the load applied to the walking training device 10 by the user when the user falls. The load applied to the walking training device 10 by the user when the user falls can be measured by the suspension load-relieving device 14. The load applied to the walking training device 10 by the user when the user falls can be calculated by subtracting the load measured by the load measuring device 161 from the known weight of the user. The load applied to the walking training device 10 by the user when the user falls is preferably the load applied by the user to a connection device that connects the user and the walking training device 10.

[0064] This allows the timing determination unit 210 to determine the timing for maintenance of the walking training apparatus 10 based on the load actually applied to the walking training apparatus 10 by the user when he or she falls.

[0065] In another embodiment, the number of falls of the user can be used as the evaluation value. In this case, the walking training device 10 transmits the identification information of the walking training device 10 and the number of falls of the user to the management device 20 as log information. The number of falls of the user based on the durability of the connected device can be used as a threshold value used to determine the timing of maintenance of the walking training device 10. The number of falls of the user based on the durability of the connected device is obtained by a durability test of the connected device.

[0066] Furthermore, in another embodiment, the walking training device 10 may execute the functions of the management device 20. Specifically, the walking training device 10 determines the timing for maintenance of the walking training device 10, and when the timing for maintenance of the walking training device 10 arrives, it can transmit a notification to that effect to the notification destination device 30.

[0067] A program according to an embodiment of the present invention includes a set of instructions (or software code) that, when loaded into a computer, causes the computer to perform one or more functions described in the embodiment. The program may be stored on a non-transitory computer-readable medium or a tangible storage medium. By way of example and not limitation, computer-readable media or tangible storage media include random-access memory (RAM), read-only memory (ROM), flash memory, solid-state drive (SSD) or other memory technology, CD-ROM, digital versatile disk (DVD), Blu-ray® disk or other optical disk storage, magnetic cassette, magnetic tape, magnetic disk storage or other magnetic storage device. The program may be transmitted on a transitory computer-readable medium or communication medium. By way of example and not limitation, a transitory computer-readable medium or communication medium includes electrical, optical, acoustic, or other form of propagated signal.
