  Next, a communication method in the safety management system 100 and the external host 90 will be described. First, in a relatively small-scale safety management system 100 that is used indoors or the like, the footwear 80 with the walking information acquisition function and the external host 90 perform transmission / reception by the power-saving short-range wireless system described above. In this case, the external host 90 includes a portable terminal such as a personal computer or a smartphone in addition to a dedicated mechanical device. According to this configuration, the user himself or his / her family can monitor the user's walking state and the like. Further, an external personal computer, a portable terminal, or the like may be used as the external host 90 using the Internet line. According to this structure, the family etc. who live apart can monitor the walking state etc. in a user's house.

  In addition, in a relatively medium-sized safety management system 100 used in a nursing facility, a medical facility, a rehabilitation facility, a welfare facility, etc., for example, a wireless repeater is installed in each place in the facility, and a walking information acquisition function is performed by a short-range wireless system. It is preferable to perform transmission / reception between the footwear 80 and the external host 90. As the external host 90, it is preferable to use a dedicated device or a personal computer installed in the facility.

  Further, in the large-scale safety management system 100 that can be used outdoors, a well-known wide-area wireless communication system is used for information transmission between the footwear 80 with the walking information acquisition function and the external host 90 as described above. As the external host 90, a contractor's personal computer or portable terminal connected via an Internet line is used in addition to a dedicated equipment server. In addition, in these medium-sized to large-scale safety management systems 100, the position of the user can be roughly grasped from the position of the base station or the wireless repeater that has received the walking information. Then, by notifying this position information to portable terminals or the like (notification means) of persons concerned such as staff and protection officers, it is possible to quickly protect a user who is in a state of danger of falling or falling. Further, in the large-scale safety management system 100 that can be used outdoors, the footwear with a walking information acquisition function 80 is provided with position information acquisition means using GPS, and the position information is transmitted to the external host 90 together with the walking information. Also good. According to this configuration, since the position of the user (the footwear with footage information acquisition function 80) can be specified in more detail, the user can be protected more quickly outdoors. When the external host 90 monitors a plurality of footwear 80 with a walking information acquisition function as described above, the communication means 34 transmits different caller identification information for each footwear 80 with a walking information acquisition function, and the external host 90 The plurality of footwear with walking information acquisition function 80 is identified by the caller specifying information.

  Next, the operation of the footwear 80 with the walking information acquisition function and the safety management system 100 according to the present invention will be described. First, a user, an administrator, or the like places the footwear with walking information acquisition function 80 at a predetermined position of the shoe rest 40. This predetermined position is a position where the flat coil 24 on the footwear 80 side with walking information acquisition function and the power feeding coil 42 on the shoe rest 40 side face each other. Then, the charging switch of the shoe holder 40 is turned on. As a result, the power supply unit 48 of the shoe holder 40 applies a commercial power supply to the feeding coil 42 at a predetermined voltage, for example, a high frequency voltage of 100 kHz. Thereby, the magnetic field according to the direction of the high frequency voltage is alternately generated from the feeding coil 42. An induced current flows down to the flat coil 24 adjacent to the power supply coil 42 due to electromagnetic induction of the power supply coil 42.

  The control unit 30 of the footwear with walking information acquisition function 80 confirms the remaining charge of the storage battery 26 when detecting the induced current flowing down to the flat coil 24. Flow down to the converter. The DC conversion unit includes a well-known rectifier circuit and a smoothing circuit, and rectifies and smoothes the AC induced current from the flat coil 24 and outputs it to the storage battery 26 as a DC current of 4.5 V, for example. Thereby, the storage battery 26 of the footwear 80 with the walking information acquisition function is charged, and the footwear 80 with the walking information acquisition function is in the charging mode. At this time, the shoe holder 40 or the footwear with walking information acquisition function 80 may light up a charging indicator or the like to notify that the footwear with walking information acquisition function 80 is being charged. Moreover, you may make it the control part 30 switch the flat coil 24 used for charge according to the charge remaining amount of the storage battery 26 at this time. For example, when the remaining amount of charge of the storage battery 26 is small, both the flat coils 24 are charged to perform quick charging of the storage battery 26, and when the remaining charge amount is large, one of the flat coils 24 is charged. In this case, normal charging may be performed.

  And when the storage battery 26 will be in a full charge state, the control part 30 will stop charge and will transfer to standby mode. At this time, the shoe holder 40 or the footwear with walking information acquisition function 80 may be lit with an indicator or the like indicating the completion of charging.

  Next, the footwear with walking information acquisition function 80 is removed from the shoe rest 40 for use by a user or the like. At this time, the control unit 30 of the footwear 80 with the walking information acquisition function detects that the induced current flowing down to the flat coil 24 has disappeared, operates the walking information acquisition unit 32 and the communication means 34, and shifts to the operation mode. And a user wears the footwear 80 with a walk information acquisition function, and performs a movement and rehabilitation. The control unit 30 monitors the remaining charge of the storage battery 26, and when the remaining charge is low, turns on the charge indicator and warning light in another light emission state to notify that the remaining charge of the storage battery 26 is low. You may make it do.

  When the user walks wearing the footwear 80 with the walking information acquisition function, the walking information acquisition unit 32 acquires the acceleration or the like applied during walking as the user's walking information and transmits it to the control unit 30. The walking information at this time includes wobbling information such as disturbance of the acceleration signal and acceleration signal in the lateral direction of the user. And the control part 30 outputs this walk information to the communication means 34 suitably, and the communication means 34 transmits these walk information to the external host 90. In addition, when the footwear with walking information acquisition function 80 has position information and physical information, the control unit 30 outputs the information to the communication means 34 and transmits it to the external host 90.

  Then, the external host 90 determines at least the user's wobbling state based on the received walking information. Here, in many cases, an elderly person breaks a bone due to a fall during walking and enters a serious care state such as bedridden. And in addition to causes such as collision and whirling at steps, a fall often occurs during walking wandering due to fatigue or reduced consciousness. Therefore, the external host 90 satisfies a predetermined condition such as when the received walking information continues, for example, a horizontal step for a predetermined number of times or the acceleration signal disturbance indicates a predetermined threshold value or more. Furthermore, it is determined that the user's wobbling state of walking is a risk of falling. Then, the external host 90 transmits a warning signal to the footwear with walking information acquisition function 80 that is determined to be in a fallover dangerous state. At this time, the external host 90 may notify the notification means such as a portable terminal set in advance by e-mail or the like that the user is in a risk of falling.

  The control unit 30 of the footwear 80 with the walking information acquisition function operates the warning means 28 in response to the warning signal from the external host 90 described above. At this time, if the warning means 28 is a warning light, the warning light is turned on or blinks. Then, when a related person such as a staff member in a nursing facility or a hospital finds a user who operates the warning means 28, an appropriate fall prevention measure such as protecting the user is performed. Note that the operation of the warning means 28 basically continues unless a release operation such as placing the footwear with walking information acquisition function 80 on the shoe rest 40 is performed.

  The safety management system 100 according to the present invention estimates the user's fatigue level from the number of steps of the user based on the walking information, the walking distance, and the like, and is in a risk of falling when the user's fatigue level exceeds a predetermined threshold. A warning signal may be transmitted. According to this configuration, it is possible to issue a warning about the danger of falling not only based on the wobbling state of walking but also on the fatigue level of the user. In addition, the control part 30 of the footwear 80 with a walk information acquisition function may perform determination of these fall danger states. According to this configuration, since the control unit 30 directly performs the determination of the wobbling state and the operation instruction to the warning unit 28, high operation reliability can be obtained.

For example, in the safety management system 100 capable of grasping the position, when the external host 90 detects that the footwear 80 with the walking information acquisition function has moved out of a predetermined area such as outside the facility, the external host 90 acquires the walking information. A warning signal is transmitted to the functional footwear 80 and the warning means 28 is operated. And by making the meaning of the warning means 28 of the footwear 80 with the walking information acquisition function known to neighboring residents and the like, a user who has moved outdoors against the intention of the facility can be detected and protected at an early stage. Further, the external host 90 transmits a warning signal when walking information is received outside a predetermined time such as midnight. Further, this is notified to the notifying means of the person concerned. Thereby, a user's late-night glory etc. can be discovered and prevented early. At this time, the external host 90 can transmit a different warning signal for each cause of warning, and the warning means 28 protects the user if it has a configuration for changing the color development or lighting pattern according to the plurality of warning signals. The person concerned can confirm the cause of the warning by confirming the display of the warning means 28, and can immediately take appropriate measures. Further, in this configuration, when the walking information acquisition function-equipped footwear 80 is used at night, the external host 90 may transmit a signal for lighting a warning light (warning means 28) in white, for example. According to this configuration, the warning light functions as an illumination light that illuminates the user's feet at night, and also functions as a recognition light that informs the user of the presence of the user.
