Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a personal information terminal for measuring the movement, posture, behavioral state and physiological state of a human.

[0002]

2. Description of the Related Art In recent years, nursing care for the elderly has attracted attention in the context of the advent of an aging society. In particular, nursing care for patients with dementia and elderly people with wandering is very important, and various techniques have been proposed. It is considered that the means of tracking the behavior of these elderly people and notifying the person or the outside when abnormal behavior is performed is very effective from the viewpoint of nursing care. Also, if we can measure and analyze not only elderly people but also human behavior, for example, we can obtain behavior patterns,
Lighting and air conditioning can be controlled comfortably and operated safely, which is very effective for human life.

[0003] Furthermore, it is effective to measure behavior and the like not only in humans but also in animals and machines. In the case of animals, it is possible to use them for research on ecology that was unknown until now. If the operation can be measured, it can be operated efficiently and safely, which is very effective from the viewpoint of production activities and the like.

[0004] By the way, in grasping the behavior of the human body,
It is very important to capture who (what), where and what. For that purpose, it is necessary to identify an individual, detect a position in a room, and detect an action and a posture.

[0005] Methods for identifying individuals include RF-ID and CCD.
There is a method based on image recognition from an image. RF-I
D is an antenna connected to a processing device such as a computer (also referred to as a reader; referred to as an antenna hereinafter) for identifying information of a tag (also referred to as a transponder; hereinafter, referred to as a tag) attached to a mobile object such as a human body or an object. Is a system that receives a radio wave of a specific frequency and automatically identifies an object.

This system can be roughly classified into two types according to the tag reading distance. One is a short distance type using low frequency, and the reading distance between the tag and the antenna is 50c.
m or less. Generally, the tag is held over an antenna, or the tag is sewn to the end of pants, and read with an antenna installed on the floor. The other is
This is a long-distance type using microwaves, and the reading distance between the tag and the antenna exceeds 1 m. By carrying them on a part of a body or a part of an object, they can read tag information without being conscious when passing near an antenna.

As a method of detecting an operation or a posture, a method of discriminating a stationary state and an operation state using a pedometer (registered trademark), a mercury switch, or the like has been proposed in the past. Recently, various acceleration sensors and gyro sensors (angular acceleration sensors)
Have improved performance, and using them, the walking state, body tilt,
A method of detecting a walking direction or the like has been proposed.

[0008]

As described above, various methods have been proposed for the purpose of detecting "who (what)", "where" and "what". Can only satisfy a single function. In other words, it is not possible to comprehensively determine “who (what)”, “where” and “what”.

[0009] RF-ID is capable of identifying a specific individual or object entering a room.
Even if a method of specifying the position of a human body or an object is used, it is impossible to determine “who (what)” or “where”. Further, even if the posture can be detected using the acceleration sensor, for example, it is impossible to determine at which position the posture is being taken.

There are also some problems in the above-mentioned method. In the RF-ID mentioned as a method for identifying an individual or a specific object, the short-distance type needs to intentionally hold the tag over the antenna because the communication distance between the tag and the antenna is short. On the other hand, since the long distance type has a long communication distance between the tag and the antenna, it may not be recognized only when passing through an entrance such as a room, but may be recognized only by passing by the antenna without entering the room. is there.

[0011] It is very important to accurately, promptly and efficiently introduce such personal behavior information into a network in order to enhance reliability.

However, conventional information for specifying “where” is located, information for specifying a posture or an activity state, physiological information, and the like are obtained, and the information is obtained from a predetermined base. In a personal information terminal transmitting to a station, unless a signal is input to the signal processing means, the signal processing means cannot process the signal, and the personal information terminal cannot transmit information to the base station. there were.

In view of the above-mentioned conventional problems, the present invention retransmits information to a signal processing unit when there is a communication error between a transmitting unit for transmitting information to a signal processing unit and the signal processing unit. An object of the present invention is to provide a personal information terminal that includes at least a transmitting unit and a signal processing unit that processes information, and that transmits acquired information to a base station.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described below with reference to FIGS.

(Embodiment 1) A personal information terminal according to Embodiment 1 will be described with reference to the drawings. FIG. 1 shows the internal configuration of personal information terminal 6 according to Embodiment 1 of the present invention. The configuration in the present embodiment will be described below. The personal information terminal 6 according to the present embodiment includes an RF-ID coil 201, an acceleration sensor 204, a gyro sensor 206, and a reception processing circuit 210 as a sensor group. The reception processing circuit 210 includes the ring sensor 2
It is a means for receiving the physiological information from 05.

The information from each of the RF-ID coil 201, the acceleration sensor 204, the gyro sensor 206, and the reception processing circuit 210 is sent to the sensor CPU (1
-1, 1-2, 1-3), further processed by the communication CPU 2, and the signal-processed data is wirelessly transmitted from the wireless module to the base station 7.

When the person carrying the personal information terminal 6 passes near the RF-ID coil mat, the RF-ID
The position of the person can be detected by the ID coil 201. Further, the posture, action, and activity state of the human body can be always detected by the acceleration sensor 204. Further, a physiological state such as a heartbeat can be constantly detected by the ring sensor 205. A physiological condition such as a pulse and a heart rate of a human body is detected by a ring sensor 205 which is a physiological condition detecting device, and a physiological signal transmitting device transmits an analog signal obtained from the physiological condition detecting device.

An analog signal obtained from the physiological signal transmitting means is always received by the reception processing circuit 210, and the received analog signal is sent to the sensor signal processing means (sensor CPU).
And a communication CPU) perform signal processing and convert the digital signal. The wireless module transmits the digital signal obtained by the signal processing means to the base station 7.

The gyro sensor 206 detects the position of the human body carrying the personal information terminal 6 in the room. The personal characteristic information obtained from these sensors is processed by the sensor CPU, further converted into a wireless communication data format by the communication CPU, and then transmitted to the base station 7 via the wireless module as personal characteristic information. Transmitted wirelessly.

When the information received by the base station 7 is analyzed and an abnormal state is determined / predicted, the information to that effect is wirelessly transmitted to the personal information terminal 6 and the buzzer 2
Level 03. As a result, the abnormality can be notified to the person or the other person. Further, a switch 202 is provided in the personal information terminal 6 for responding to the sound of the buzzer or for contacting when the person determines that the person is abnormal.

By the way, if there is a communication error between the CPU, such as the RF-ID coil 201, the acceleration sensor 204, the gyro sensor 206, and the reception processing circuit 210, the data collected by the sensor is conventionally used. There is a problem that information is not transmitted to the base station 7.

However, in the present embodiment, when there is a communication error between each sensor and the CPU, each sensor retransmits information to the CPU again. Each sensor holds information until the CPU receives the information. In this way, the information collected by the sensor is reliably transmitted to the base station 7.

When the CPU receives the data from each of the above sensors, it sends received information to that effect to the corresponding sensor.
U can know that it has been received, eliminating the need to keep that information. In addition, each of the above sensors is a CP
The information to be transmitted to U may be transmitted with a command to return the received information to that effect when received. In this case, when each sensor receives the received information from the CPU, the information transmitted by itself is transmitted. Is received by the CPU, and it is not necessary to hold the information.

In the case where the information collected by each sensor is periodically transmitted, when the CPU does not receive information from each sensor, the CPU transmits non-reception information to that effect to the sensor. Then, the sensor can know that the information transmitted by the sensor has not been received by the CPU, and can retransmit the information. As a result, the information collected by the sensor is reliably received by the CPU.

It should be noted that the information transmitted periodically is CP
If not received by U, the information is retransmitted, but the information after retransmission may be transmitted from the sensor to the CPU at the transmission timing when there is no communication error, or may be retransmitted. The information may be transmitted from the sensor to the CPU periodically from that point on a time basis.
