[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention prevents an infant, an elderly person with dementia, etc. from getting out of a safe home and losing their whereabouts without being noticed by a family member. The present invention relates to a whereabouts detection device that can be effectively used to detect a.

[0002]

2. Description of the Related Art In a family with infants and elderly people with dementia, it is almost necessary to protect them with care, and even if they do so, they may get out of a safe house when they take a short distance. is there. If an infant or an elderly person with dementia goes out alone, there is a risk of being in a traffic accident or injuring by falling over a step or a groove. In many cases, it is difficult to find it because it is completely unknown.

However, conventionally, no suitable device has been provided as a device for detecting the whereabouts of an infant or an elderly person with dementia and detecting its whereabouts. The current situation is that we are in great trouble.

As a similar technique applicable from a technical point of view, an infrared detector for detecting that a person approaches an automatic door or the like, or, for example, as disclosed in JP-A-5-12576, There is known an anti-theft device or the like in which an alarm provided on the product or fixed equipment is activated when the product is taken out of a certain area without permission.

Further, as a method of detecting the moving destination of a person or the like, a method of attaching a transmitter to a person or the like and detecting and tracking the transmitting direction by the detector has been considered.

[0006]

However, even if an infrared detector is provided at the entrance / exit, even if an alarm can be issued when a person passes through the entrance / exit, the alarm is almost not noticed or cannot be released. Not only can the effects not be exhibited, but there is also the problem that handling will be inconvenient because a warning will be issued to anyone.

Further, when the anti-theft device to be mounted on the product disclosed in the above publications is applied, the alarm cannot be detected but the whereabouts cannot be detected, so that the sufficient effect cannot be obtained. There is a problem.

Further, it is possible to install the transmitter on the body or clothes of an infant or an elderly person with dementia and install a radio wave detector for receiving the radio wave, but it is not clear when it went out, and it was considerably Power consumption is high because the transmitter that constantly receives radio waves over a wide area is in the operating state, and the power supply battery consumes a lot of power. There is a problem that it is scarce, and there is a problem that when it moves out of reach of radio waves, there is no clue at all. Further, it is also a fatal problem that the location of a person cannot be detected accurately only by detecting the direction of transmission of radio waves.

In view of the above-mentioned conventional problems, the present invention has a high reliability because the alarm is continuously issued when the user exits the set area, the direction of the current position can be detected, and the ineffective power consumption is small. An object of the present invention is to provide a whereabouts detecting device that can be used with certainty and a whereabouts detecting device that can accurately detect the whereabouts of a person.
