Description

  The present invention relates to an electronic device having a function of reliably tracking a movement of a person applied to a position information system, and more particularly, an action having a light emitting function that is worn by a moving elderly person or schoolchild. The present invention relates to a small thin electronic device for monitoring.

  In recent years, various IC tag systems have been developed by applying an IC reader system that attaches an electronic tag, that is, an IC tag to an article and reads the IC tag information. This wireless tag (RFID: radio frequency identification) is an integrated circuit (IC) chip that performs short-range wireless communication and information processing, and is small and power-saving. Therefore, it is used in the field of monitoring human behavior. Is expected.

  For example, with the increase in nuclear families and dual-income families, there is an increasing demand for behavior monitoring systems for monitoring the behavior of children such as elementary school students and monitored persons such as elderly people with disabilities. This behavior monitoring system allows a person to be monitored to wear an IC tag, to carry a portable terminal equipped with a GPS function or a PHS telephone system, and to receive a position detection signal obtained from the IC tag or the portable terminal. This is a method of notifying the observer of the current position of the observer.

In particular, care for elderly people has attracted attention in recent years due to the arrival of an aging society. In wards and general households where the elderly are, there are cases where there are elderly people with cognitive symptoms as guardians. For elderly people with cognitive symptoms, it is required that managers and caregivers go out of their own spaces such as buildings and gardens without permission, manage and monitor them so that they do not get lost. Conventionally, in the unlikely event that a guardian escapes or hesitates, various devices and systems have been proposed in order to search for the victim quickly. Examples of methods for monitoring elderly people include the human body. And a personal information terminal that can be attached to the human body having a sensor signal transmission / reception means for transmitting a state detection signal based on the behavior detection, and based on the processing result, A state information collection system that obtains state information indicating a state is disclosed (for example, see Patent Document 1).

  In addition, there is disclosed a clothing in which a GPS mobile terminal is fixed to the wearer's clothes so that the wearer cannot remove it and further has an antenna part on the shoulder or the like so as to minimize the shielding by his / her body etc. (For example, refer to Patent Document 2).

  In addition, the current position information of the monitored person terminal carried by the monitored person (for example, a deaf person) is acquired based on the GPS system and moved outside the action area set in advance by the monitored person. In this case, a behavior monitoring system that transmits a warning signal to a supervisor terminal is disclosed (for example, see Patent Document 3).

Also, as a field other than the monitoring of elderly people, in order to monitor medical data, in particular, the state of the patient's cardiovascular condition, blood characteristics, etc., it is equipped with a receiving part and a transmitting part, a measuring sensor, and measured data A patient monitoring system including a means for transmitting and receiving and a location confirmation system module for transmitting the location of the patient is disclosed (for example, see Patent Document 4).
In addition, as another field, there is known a method of using a wireless tag or a mobile phone for a so-called child watching service for confirming a child's going to / from school and grasping a route at the time of going to / from school.

  In the case of this example, a wireless base station having the function of a wireless tag reader is arranged at the school gate or school route. Each base station collects the ID information of the wireless tag from the wireless tag embedded in the carry-on item such as the school bag of each child. As a result, it is possible to collect information regarding which wireless tag has passed through which base station's wireless communication area. Then, from the collected data, it is possible to confirm the passage of each child through the school gate and estimate the route and position.

  For example, in Patent Document 5, as a method for preventing accidents such as removal of children when they go to school and ensuring the safety of children, a child on the way to and from school has a wireless tag, and a communication terminal such as a mobile phone, A method for detecting a wireless tag carried by a child and confirming whereabouts has been proposed.

  In addition, “commuting mobile phones” that can check a child's whereabouts and attendance using a mobile phone are provided (see, for example, Non-Patent Document 1).

  However, in the search using the monitoring system for senior citizens and the monitoring system for school children, the means to be worn by the target person is forced to use a mobile phone or a communication device in order to detect human behavior such as the deceased and children. It is difficult to say that it is a means that can be possessed by a person or a large transmitter or the like, and that a deaf person or a child does not have a sense of incongruity and can actively possess and attach a communication apparatus or the like without being aware of it. In addition, these means often have a communication function but do not have an image display means. For this reason, when a dangerous situation is encountered at the time of drought or going to / from school, a message etc. cannot be displayed to the surrounding people to notify the danger, or the device being used, such as a battery, etc. Since the remaining amount of the battery is not displayed, the battery runs out of time and the transmission is disabled.

  In other cases, when searching for missing pets such as dogs and cats, ask a specialist or search for posters with pet photos posted in areas where pets are likely to move. It is only the method, and the probability that it can be found is very low at present.
