DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an environment control device for realizing control of house equipment based on a stress state of a resident and a care house equipped with the same.

2. Description of the Related Art Conventionally, a device for controlling a physical quantity as a stimulus for giving a sense of comfort by referring to a physiologic quantity of a resident is widely used as a housing equipment. For example,
There is one described in Japanese Patent No. 95348. In this method, an electroencephalogram signal obtained by an electroencephalogram sensor attached to a resident is frequency-analyzed, and an air conditioner is controlled by power of an α-wave component. Further, there is a technique for detecting a human pulse wave described in JP-A-3-137448 and a technique for controlling an air conditioner by detecting a human skin potential level described in JP-A-4-103942. . These are all technologies for controlling an air conditioner using a human bioelectric signal.

There is also a technique for detecting the comfort of a resident in a non-contact manner without using a bioelectric signal and controlling housing equipment.
For example, there is a technique described in JP-A-7-55226. It detects the occupants' movements in a non-contact manner by means of infrared detection means, ultrasonic transmission / reception means, and imaging means, estimates the level of comfort from physiological and psychological states based on their movements, and estimates housing facilities such as air conditioning and lighting This is a technology for controlling equipment.

[0004]

However, it is difficult to evaluate the state of the body in the first place with the above-mentioned technique for detecting only the brain wave or only the movement among the body information. For example, in the above-described technology for detecting a motion and detecting the occupant's physical condition in a non-contact manner, for example, even if the occupant's supine position is detected, it is not possible to distinguish between a nap or a sickness. It is difficult to estimate the physiological and psychological state of a person. Further, it is impossible to simultaneously process, accumulate and evaluate data indicating the physiological and psychological states of a plurality of residents.

Also, environmental factors such as heat, light, air quality, etc. have a combined effect on the human body, and therefore there are the most effective combinations for the human body.

Accordingly, the present invention detects physical conditions such as the degree of comfort and tension of a resident by using physiological information and behavioral information together, and optimally controls housing equipment for the individual based on the physical conditions. The purpose of the present invention is to provide environmental control equipment.

(Embodiment 1) Embodiments of the present invention will be described below with reference to the accompanying drawings. FIG. 1 is a block diagram of an environment control device according to the present invention. In FIG. 1, reference numeral 1 denotes body motion detection for detecting body motion of a resident, that is, information on movement such as posture change and walking, and fine vibration of a trunk, particularly vertical acceleration of the trunk, which is an effect of antigravity muscles. Means 2 are physiological information detecting means for detecting the resident's autonomic nervous system function, particularly cardiac function, 3 is the body movement detecting means 1,
Based on the signals output from the physiological information detecting means 2 and abnormal behaviors such as mental tension, relaxation, and fall, physical states including cardiac function states are specified, and the set values of the environmental factors corresponding thereto are specified. The physical information specifying means 4 for outputting data is communication means for mediating data communication between the physical information specifying means 3 and the environmental factor control means 5 and data communication between the environmental factor control means. Reference numeral 5 denotes an environmental factor control unit including at least one or more of a heating element, a heat absorbing element, a blower, a dehumidifier, a humidifier, a light source, a sound source, and a true air generator.

Since the autonomic nervous system function of a human, particularly the heartbeat, is affected by body movement such as physical activity, body movement detection is indispensable for automatic measurement of heart function. Therefore, the output from the physiological information detecting means 2 in the environment control device according to the present invention is characterized in that the physical information specifying means 3 is selected depending on the state of the occupant's body movement. This feature enables automatic detection of cardiac function and detection of stress response in the autonomic nervous system without being affected by body movement and body position. In addition, a control signal corresponding to the stress response detected via the communication means 4 is transmitted to the environmental factor control means 5, and the environmental factor control corresponding to the control signal is performed to reduce acute stress.

In the above configuration, the body movement detecting means 1 detects the body movement of the occupant, ie, information on posture change, movement such as walking, and fine vibration of the trunk, and outputs the information to the body information specifying means 3 to detect physiological information. The means 2 detects the resident's brain waves, eye movements, myoelectric potential, skin electroreflection, skin temperature, sweating reflex, especially cardiac function, and outputs it to the physical information specifying means 3. The physiological information when the resident's body is at rest is extracted from the motion information and the physiological information, and the resting physical state is calculated and estimated. As an example,
An environmental control method for detecting an acute stress response from body movement information and physiological information in the physical information specifying means 3 to alleviate acute stress will be described. When detecting an acute stress response, the physiological information detecting means 2 detects an R wave in an electrocardiogram. The physical information specifying means 3 monitors the input from the body movement detecting means 1 and stops the physiological information detecting means 2 when there is a body movement of a level accompanied by the movement of the center of gravity. Performs information detection. When the chair resting state for 20 minutes is completed, the physical information specifying means 3 starts counting R waves and measures the RR interval in the electrocardiogram. When the average RR interval is shorter than the normal value, or the coefficient of variation CVR-R of the RR interval standardized by the average value of the standard deviation of the RR interval is smaller than the normal value, the autonomic nervous function is enhanced than usual, It is determined that the body has a burden on homeostasis. At this time, the physical information specifying means 3 transmits an acute stress elimination signal to the environmental factor control means 5 via the communication means 4. The environmental factor control means 5 having received the acute stress relieving signal sets the indoor thermal environment setting value by air conditioning to PMV = 0, the lighting color temperature setting to about 3500 K (bulb color), or the atmosphere near the resident to 10,000.

According to the above operation, the environmental control apparatus of the present invention is characterized in that the physical information specifying means 3 uses the body movement information input from the body movement detection means 1 and the physiological information input from the physiological information detection means 2 to inhabit. The state of tension and relaxation of the mind and body of the resident is determined, and the environmental factor set value is calculated according to the state of tension and relaxation of the resident of the resident. The environmental factor control means 5 controls the environmental factor of the environment in which the occupant is staying, and has an environmental factor control action adapted to the physiological condition of the occupant.

Conventionally, in the field of thermal environment, it has been known that an autonomous thermoregulatory reaction is minimized in a thermal neutral state. This means that the activity of the autonomic nervous system increases when the temperature becomes colder or hotter than the thermal neutral state,
It exhibits a kind of stress response, but in the thermal neutral state, the activity of the autonomic nervous system is reduced, and the stress response of the living body is minimized. In addition to the thermal environment, the correspondence between the color temperature of the illumination light source and the activity of the autonomic nervous system is shown. In addition, the action potential of nerve fibers in a living body and the cation dependency of muscle tone suggest that anion present in the air has an effect of relaxing the tone of the living body. These facts show a close relationship between the home equipment such as air conditioning equipment, lighting equipment, and air purifiers and the human homeostasis maintaining function controlled by the autonomic nervous system. The environmental control apparatus according to the present invention focuses on this relation, and realizes environmental control adapted to the characteristics of the function of maintaining homeostasis by using the housing equipment.

In addition, a CCD camera and an infrared sensor are used as an alternative to the body movement detecting means, and the body movement is detected by image processing. The same effect can be obtained by using a detecting means. In the present embodiment, the electrocardiogram detecting means including a plurality of electrodes is used as the physiological information detecting means, and the action potential of the myocardium is output to the physical information specifying means.
