JP2009020847A - Location specifying system by tag shaped compact radio transmitter and electric light line communication - Google Patents

Abstract

<P>PROBLEM TO BE SOLVED: To achieve a location specifying safety system using electric lamp line communications without need of special construction as a compact, light and safe location specifying system is required in order to prevent accidents accompanying approaching a dangerous place or a sole behavior through an entrance and to eliminate psychophysical burdens where elderly people and physically handicapped persons live in an institution. <P>SOLUTION: A TAG shaped compact radio transmitter is fixed to clothing of a person requiring care, and weak radio waves (2.4 GHz range) transmitted therefrom at regular time intervals are received by a plurality of receiving controllers installed in the institution. The data is sequentially transmitted to a management device through an electric lamp line communication line. The management device calculates individually the TAG shaped compact radio transmitter data from the plurality of receiving controllers and displays the data in real time. When the receiving controller beforehand installed near the dangerous place receives the electric waves, an alarm is issued onto the management device. This means is also applicable to a location specifying system for a healthy person. <P>COPYRIGHT: (C)2009,JPO&INPIT

Description

    The present invention relates to a position specifying system in a hospital, an elderly facility, and other facilities (factory / office, etc.).

    When elderly people or people with disabilities are living in a facility, it is important to specify where they are located. It is also important to know where a person is in order to ensure the safety of a person with inertia. In addition, it is useful for a healthy person to know whereabouts in a large facility. In this method, a person who needs to know where the facility is located attaches a small TAG-shaped wireless transmitter to his / her clothing, receives the weak radio waves with multiple reception controllers installed in the facility, and measures the radio field strength sequentially. An invention related to a system that can specify whereabouts.

    Conventionally, when elderly people or people with physical disabilities are active in the facility, there is a method of knowing where they are, but there is a large positional error, making it impossible to specify the detailed location. .

    It is difficult for an elderly person to always have a large transmitter or a heavy transmitter.

    In a large facility, there are limits to the caregiver's ability to manage access to dangerous places and going out of the entrance for multiple elderly people.

    In addition, in a large facility, searching for a specific staff member is limited in a short time.

    An embodiment of the present invention will be described with reference to FIGS.

    The TAG-shaped small wireless transmitter of the present invention is attached to the clothes of a care recipient.

    The TAG-shaped small wireless transmitter of the present invention transmits a weak radio wave in the 2.4 GHz band at regular intervals.

    The reception controller of the present invention individually receives 2.4 GHz charged waves from all TAG-shaped small wireless transmitters, and transfers the received data to the management device by power line communication.

    The reception controller performs reception sensitivity setting from the management device in advance, thereby receiving only short-distance radio waves and receiving long-distance radio waves and transferring them to the management device.

    The management device is operated by a program in a personal computer, and displays received data from a maximum of 100 TAG-shaped small wireless transmitters in a list and layout in real time.

    When a specific TAG-shaped small wireless transmitter approaches a receiving controller installed near a hazardous location, an alert is issued to alert the caregiver.

    As described above, the present invention does not impose any physical and mental burden on the person's life behavior in the facility of the care recipient, while constantly measuring the position of the natural life situation, and managing the information at regular intervals. It can be communicated to caregivers.

    The reception controller and management device installed in the facility use the indoor power line for the communication line, so that installation can be completed in a short period of time without requiring special construction.

    Hereinafter, embodiments of the present invention will be described with reference to FIGS. 1 and 2.

    FIG. 1 shows the arrangement of the smallest unit of the present invention.

    The TAG-shaped small wireless transmitter transmits a weak inherent radio wave at regular time intervals.

    The receiving controller constantly measures the specific radio field intensity from the TAG-shaped small wireless transmitter and transmits data to the management device using indoor power line communication.

    FIG. 2 represents a practical installation.

    In FIG. 2, it becomes possible to grasp the movement status by the management device sequentially calculating the difference in signal strength from the unique TAG-shaped small wireless transmitters received by a plurality of receiving controllers.
