DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a support system for early protection of wanderers in facilities such as nursing homes (hereinafter referred to as facilities).

[0002]

2. Description of the Related Art Various systems have been developed for the purpose of protecting wanderers, but most of them are equipped with a transmitter at a facility, and automatically when a wanderer approaches a receiver installation location such as an entrance of the facility. It outputs an alarm sound and a lamp display.

[0003]

However, the above contents are essential as basic functions, but are not sufficient. It is only necessary to be able to protect the wandering person immediately upon occurrence of the alarm, but the person may go outside in time. Therefore, there is a system that automatically locks the entrance door when an alarm occurs, but since ordinary people enter and exit the facility, there are cases where wandering people get out and get lost by those people. There are limits to how much you can stop with your system. In addition, the staff of the facility may not notice the alarm due to the busyness, and after a while it finds that a wandering person has gone out and searches in a hurry.

The present invention has been made in order to solve the above-mentioned problems, and in addition to a conventional wandering person protection system, a system for assisting a search for a wandering person who could not prevent going out quickly and without waste. The purpose is to provide.

[0005]

A wandering person early protection support system according to claim 1 is a system for preventing a wandering person from going out alone in a facility such as a nursing home and providing protection support when going out alone. The facility opening time zone is constantly acquired by alternately switching the camera directed toward the outside and the camera directed toward the outside, and the alarm signal is output based on an alarm signal when a walker outside is detected by a tag attached to the walker and a sensor installed at the entrance of the facility. By switching the image acquisition mode of the camera,
More detailed image acquisition, a personal information database created and stored in advance, and monitoring of the two acquired images by the facility staff who has confirmed the chime sound based on the alarm signal, and confirmation of the reproduced image, identify the wandering person who has gone out. With
It is characterized by displaying on-screen the outfit, going-out direction, going-out time, the personal information search result of the wanderer, and the narrowed moving range.

According to the system for supporting early protection of a wandering person according to the first aspect, not only is it possible to prevent the wandering person from going out alone, but if the individual cannot go out alone, the wandering person is specified and the characteristics of the person concerned are specified. Since the elapsed time from the outside, the walking speed, and the movement range narrowed down from the outside direction can be instantaneously grasped, the person can be searched without waste.

A wandering person early protection support system according to a second aspect of the present invention is a system for preventing a wandering person from going out alone in a facility such as a retirement home and providing protection support when going out alone. The system is searched from a personal information database created and stored in advance. The moving range of the person who goes out is displayed on the map on the screen by referring to the walking speed of the person who goes out, the map information around the facility, and the elapsed time from the time of going out.

According to the wandering person early protection support system of the present invention, a map of the moving range of the wandering person requiring protection is displayed on the screen, so that the corresponding person can be searched without wasting the search range.

According to a third aspect of the present invention, a wandering person early protection support system is a system for preventing a wandering person from going out alone in a facility such as a nursing home, and protecting the person from going out alone. In this case, the personal information database created and stored in advance is searched from the ID code of the tag, and the personal information of the person is automatically displayed on the screen.

According to the third aspect of the present invention, the personal information of the wandering person requiring protection is automatically displayed on the screen. Omitting, and unlike the case of judging from the appearance of the image of the camera, the person is not mistaken.

DESCRIPTION OF THE PREFERRED EMBODIMENTS An actual operation example of the present invention is shown in FIG.
A description will be given based on a few items. FIG. 1 is a sketch drawing showing one embodiment of the present invention. In FIG. 1, 1 is a tag attached to the clothes of a wanderer, and 2 and 3 are sensors that react to the tag 1.
Indicates the inside of the facility entrance, and 3 indicates the outside of the facility entrance. For example, an RFID card can be used for the tag 1 and an RFID reader can be used for the sensors 2 and 3 to enable identification of a personal ID. 4 is an automatic door at the entrance of the facility,
Reference numerals 5 and 6 denote CCD cameras, 5 being directed toward the inside of the entrance and 6 being directed toward the outside of the facility. 7 is from 2 to 6
And a process controller (hereinafter, referred to as a PC) connected to the above components and controlling the components, and has a built-in storage device. Reference numeral 8 denotes a display device connected to the PC 7.

FIG. 2 is a conceptual diagram showing a normal timing at which images from the two CCD cameras 5 and 6 are taken into the PC 7, and FIG. FIG. 3 is a conceptual diagram showing timings for capturing images from cameras 5 and 6 into a PC 7. Normally, as shown in FIG. 2, images from the inward-facing CCD camera 5 and the outward-facing CCD camera 6 are alternately fetched every N seconds, and recorded in a storage device of the PC 7 together with a time stamp. N is set in consideration of the capacity of the storage device and the facility opening time.
Usually, it is realistic to set the value to 0.5 to 2.

When the wanderer with the tag 1 approaches the entrance of the facility, the sensor 2 inside reacts and notifies the PC 7. The PC 7 having received the notification outputs an opening / closing operation stop signal to the automatic door 4 at the entrance of the facility so that the door is not automatically opened. If the wanderer with the tag 1 goes out of the facility entrance / exit for some reason, the outside sensor 3 reacts and notifies the PC 7. Upon receiving the notification, the PC 7 outputs an alarm signal, sounds a chime in the office to inform the facility staff that the wanderer has gone outside, and searches the personal information database from the ID code of the wanderer. , CC
The mode of image capture from the D camera is switched. As shown in FIG. 3, the image capturing mode when the outer sensor 3 reacts is to reduce the image from the inwardly facing CCD camera 5 to 1 / M
An image from the outwardly directed CCD camera 6 is acquired for about 10 seconds every second and for about 1 minute every 1 / M second, and is displayed on the screen of the display device 8 and simultaneously recorded with a time stamp in the storage device of the PC 7. As for M, 0.5 to 2 is effective for the present system.

The facility staff who hears the chime sound searches the personal information database created and stored in advance while looking at the display device 8 on which the image is displayed, displays the search result, and protects the wandering person if necessary. I do. If protection is not possible despite the need for protection, such as when a wandering person alone goes out, the wandering person is searched for based on the outgoing clothes, outing direction, and the like based on the reproduced image of the recorded image.

If the facility staff does not notice that the wandering person has gone out, or if the sensor does not respond, the record of the normally acquired image is reproduced when the wandering person goes out, and the above-mentioned outside sensor 3 responds. Similarly to the above, after the wandering person is specified, the wandering person is searched based on the clothes when going out and the outing direction. At this time, the search range can be narrowed down by specifying the movable range of the wanderer based on the time stamp in the recorded image and the walking speed in the personal information database.

As an example of specifying the movable range of a wanderer based on the outside time and the walking speed, the range is displayed on the screen of the display device 8 in combination with map information around the facility, as shown in FIG. Further, the search range can be narrowed down. (Claim 2) The tag 1 and the sensors 2 and 3 have R
By applying the FID device, it is possible to automatically identify a person who has gone out and search a personal information database. (Claim 3)

[0017]

According to the present invention, it is possible not only to prevent a wandering person from going out alone, but also to personally name the wandering person who goes out, clothes to go out, time to go out, direction to go out, and even to be able to move. Since the range can be specified, it is possible to quickly search for and protect wanderers without waste, thereby greatly reducing the labor of facility staff.
