2. Description of the Related Art In Japan, it is said that the ratio of elderly people aged 65 or over to the population will exceed 30% in the next 50 years. Under such circumstances, measures for the elderly requiring nursing care are currently being focused and examined, but it should not be overlooked that there are many healthy elderly people. Of the healthy elderly people, those living alone are often isolated spatially and in terms of human relationships, and it is very important to understand the health status of these people, but There is an overwhelming shortage of human resources to grasp and manage the health status of people.

Therefore, various proposals have heretofore been made for the purpose of grasping the health condition of a specified number of people with a small labor. For example, in a service system in which various sensors are arranged in a house to monitor the living activities of the elderly, or in Japanese Patent Laid-Open No. 10-248093, a sensor is attached to a household electric appliance and a hot water supply switch of an electric pot is turned on. -A system has been proposed that monitors the safety of consumers by detecting off and so on.

[0004]

However, in the technique proposed so far, it is premised that only the subject is active, so that when there is an outpatient, the detection device detects the activity by the outpatient as well. The monitoring function will be completely paralyzed.

The present invention has been made in view of such conventional problems, and accumulates the daily living activities of the subject in the most natural form while ensuring privacy, and at the same time, in the presence of an outpatient, correctly detect the activity only
The purpose is to provide a living activity detection system .

BEST MODE FOR CARRYING OUT THE INVENTION The present inventors collect the daily living activities of a subject in the most natural form while ensuring privacy, and at the same time, correctly detect only the subject's activity even when there is an outpatient. As a result of earnest studies, it was found that the above object can be achieved by carrying a data erasing device for erasing / sorting the data detected by the detection device to an outpatient, thereby completing the present invention.

That is, in the living activity detection system of the present invention, a detection device for detecting the activity of the subject without disposing the transmitting terminal on the subject is arranged in the activity area of the subject,
Receipt and storage to thereby detect the life activity of the subject in an integrated device detecting data from該検known apparatus, a data erasing unit originating a data erasing signal by mobile the visitor, the detecting device detects any daily activity However, when the data deletion signal is received at the same time, the detection data is deleted or sorted so that only the living activity of the subject is correctly detected.

About the life activity detection system of the present invention
I will explain below. FIG. 1 shows a schematic diagram of a living activity detection system. The signals detected by the various detection devices 1 installed in the house are sent to the accumulation device 2 where they are accumulated and stored as time series data. When analyzing the time-series data to evaluate the health condition of the subject, the time-series data stored in the integrated device 2 is sent to the analysis / evaluation means 3 every predetermined time or when there is a transmission request. . The analysis and evaluation means 3 analyzes and evaluates the collected time series data. The evaluation result by the analysis / evaluation means 3 is transmitted to the subject 5 and the care / nursing / medical / welfare institution 6 as needed using the transmission means 4 and is utilized for self-management of the health condition and activities by the institution. Each means will be individually described below.

First of all, the detection device is in a non-contact state.
Those that detect the subject's activity and the subject's contact
Both of those to detect the activity of the examiner can be used. For example, air conditioner, TV, refrigerator, microwave oven,
Appliances such as mats; vibration sensor, an acceleration sensor, etc. can be used conventionally known sensor such as an infrared sensor, can be used by combining a plurality of these desirable for detecting the daily activity in more detail. For example, by using a home electric appliance as a detection device, it is possible to detect on / off of a switch, opening / closing of a door, temperature setting, operation mode, compressor rotation speed, remote control operation, power consumption, entry / exit, etc. . Also, if you install a vibration sensor or acceleration sensor on household appliances , indoor members such as toilets, bathrooms, living rooms, bedrooms, doors of Buddhist altars, furniture, floors etc. It is possible to detect at what time and at what time vibration or acceleration was detected, that is, what kind of action a person took. Further, if a vibration sensor or an acceleration sensor is attached to the gas or water pipe, it is possible to detect the usage status of the gas or water. If an infrared sensor is used as a detection device, it can detect that a person has entered a specific area.

The detection signals detected by the various detection devices 1 are sent to the integrated device 3 where they are stored as time series data. There is no particular limitation on the transmission method from the detection device to the integrated device, but it is preferable to use wireless or power line carrier transmission from the viewpoint that no new wiring work is required.

When further analyzing the time series data to evaluate the health condition of the subject, the time series data stored in the integrated device 2 is sent to the analysis and evaluation means 3.
The transmission method from the integrated device 2 to the analysis / evaluation means 3 is not particularly limited, and a telephone line or a CATV line may be used. Although the integrated device 2 and the analysis / evaluation means 3 are separate bodies in FIG. 1, both of them may of course be formed integrally.

In the above-described living activity detection system, when there is a visitor, the visitor is caused to carry a data erasing device which transmits a data erasing signal. With this configuration, even when the detecting device detects the living activity of the visitor, the detecting device simultaneously receives the data erase signal transmitted from the data eraser carried by the visitor. Therefore, the detection data is deleted or is separated and collected from the detection data of the subject and stored. As a result, the living activities of the subject are correctly collected and stored, and the living activities of the outpatient are also collected and stored as necessary.

The data erasing device which can be used in the present invention is not particularly limited as long as it has a structure for transmitting a data erasing signal, but a device using a radio transmitter or a magnetic material has portability. From desirable. Further, in order to identify the visitor, it is preferable to transmit the identification signal of the visitor together with the data erasing signal. It is desirable that the data erasing device be small and lightweight in order to reduce the burden on the visitor. Moreover, in order to completely prevent mixing of disturbance data,
The data erasing device is preferably worn before the visitor enters the house. The mounting position is not particularly limited as long as it is a position where a data erasing signal is easily transmitted and received, and may be appropriately determined in consideration of types of transmitting and receiving means of the data erasing signal, discomfort of a foreigner's wearing and the like.

FIG. 2 is a block diagram showing a configuration example of the disturbance data erasing / classifying method used in the present invention. In the data erasing device 7, the data erasing signal generated by the data erasing signal generator 71 is encoded by the encoder 72, modulated by the modulator 73, and then transmitted to the outside. At this time, when identifying the visitor, the identification signal of the visitor generated by the identification signal generator 74 is also transmitted together with the data erasing signal.

On the other hand, in the detection device 2, the sensor portion 21
The detection data detected by the encoder 22 is encoded by the encoder 22 and normally temporarily stored in the storage unit 23, and then the output unit 2
It is sent to the stacking device 3 via 4. At this time, the receiving means 2
In 5, when the data erasing signal is received, the signal is demodulated by the demodulator 251 and then decoded by the decoder 252 into the data erasing signal and the alien identification signal. When the arrival of the data erasing signal is transmitted to the storage unit 23, the detection data is not stored in the storage unit 23.

FIG. 3 shows a flowchart of control in the detection device at this time. When some living activities are detected in step S1, it is then determined in step S2 whether or not a data erasing signal has been received. If the data erasing signal has not been received, that is, if the subject's living activity is detected, the detection data is temporarily stored in the storage unit in step S3. Then, if there is a storage data transmission command from the integrated device in step S4, the stored data stored in the storage unit is transmitted to the integrated device in step S5. On the other hand, when the data deletion signal is received in step S2, that is, when the activity of the alien is detected, the detection data is not stored in the storage unit and the process proceeds to step S4. Detect activity.

As another control method, the visitor recognition unit 253 recognizes the visitor based on the decrypted visitor identification signal, and the detection data is stored in the storage unit 23 as the activity of the identified visitor. Store temporarily. Then, the detection data may be transmitted to the integrated device 3 together with the visitor information.

FIG. 4 shows a flowchart of control in the detection device at this time. Explaining only the parts different from the flowchart of FIG. 3, if some living activities are detected in step S1 and a data erasing signal is received in step S2, that is, if the activity of an alien is detected, in step S6. The detection data is stored in the storage unit as the activity of the visitor, and if the storage device issues a storage data transmission command in step S4, the detection data of the visitor is transmitted to the collection device together with the detection data of the subject in step S5.

An example of the detection data collected and stored in the integrated device in this way is shown in FIG. According to FIG. 5, for example, the refrigerator door was opened and closed by the subject at time 9:32, and the toilet door was opened and closed by the visitor A at time 9:45. It can be seen that the activities of can be distinguished and stored as time series data.

FIG. 6 is a block diagram showing the structures of the detection device and the integrated device. Although it is basically the same as the configuration of FIG. 2,
The method of processing the detection data is different. That is, in FIG. 2, the disturbance data is erased / sorted in the storage unit 23 in the detection device 2, but in FIG. 6, the detection data and the data erase signal are sent to the integrated device 3 as they are. When the detection data and the data deletion signal are sent to the integrated device 3, the detection data is deleted or stored as the activity of the visitor separately from the detection data of the subject. At this time, the visitor identification unit 2
When the information of the visitor specified from 53 is sent together, the information is also stored in the integrated device 3.

FIG. 7 shows a block diagram when a magnetic material is used as the data erasing device. When the data erasing signal based on the magnetic force transmitted from the data erasing device 7 made of a magnetic material is received by the receiving means 25, the signal is transmitted to the storage unit 23. When the reception of the data deletion signal is transmitted to the storage unit 23, the detection data detected by the sensor unit 21 and encoded by the encoder 22 is not stored in the storage unit 23. Therefore, only the detection data of the subject stored in the storage unit 23 is transmitted from the output unit 23 to the integrated device 3.

As another control mode, when the reception of the data erasing signal is transmitted to the storage unit 23, the detection data detected by the sensor unit 21 is used as the activity of the visitor.
It is stored in the storage unit 23 separately from the activity of the subject. At this time, if the alien identification signal is received at the same time, the alien is identified and the detection data is stored.

Another embodiment is shown in FIG. The basic configuration is basically the same as that of FIG. 7, but the method of processing the detection data is different. That is, the data erasing signal received by the receiving means 25 is not transmitted to the storage unit 23 but is transmitted to the integrated device 3, where the detection data is erased or sorted / stored as the data of the visitor.

[0028]

According to the living activity detecting system of the present invention, the data erasing device for transmitting the data erasing signal is carried by an outpatient, and the data is stored in the detecting device arranged in the activity area of the subject. A deletion signal receiving means is provided, and when the receiving means receives the data deletion signal, the detection data by the detection device is deleted or sorted, so that the daily life activity of the subject is kept the most natural while ensuring privacy. In addition to accumulating in the form, only the activity of the subject can be correctly detected even when there is an outpatient.

Further, the use of those using radio transmitters or magnetic material as the data erasing device, thereby the reduction of visitor mobile burden.

Furthermore, Then, as the data erasure apparatus also transmits an identification signal of a visitor with the data erase signal, can also be collected activities related visitor.

Further, in a non-contact state as a detection device
Those that detect the subject's activity and the subject's contact
At least one but to detect the activity of the examiner, among them the use of electrical equipment for home <br/> garden, can be detected in the most natural way while ensuring the privacy of the day-to-day life activity of the subject, such as the elderly .
