とができる。Most conventional human body detection devices mainly detect a human body that moves on foot or the like. FIG. 5 shows a detection area of a conventional representative human body detection device, and FIGS. 5A and 5B are views of the detection area as viewed from the front and above, respectively. Here, a round type (all around detection type) human body detection device is used. In the figure, 11 is an outer circumference detection area, 12 is an inner circumference detection area, and 13 is a direct detection area. In this human body detection device, generally, the interval between the detection areas is set to be larger than the size of a normal human body.
In the example shown in FIG. 5, the diameter l 1 of the outer periphery detection area 11 is usually
About 10 m, the diameter l 2 of the inner circumference detection area 12 is about 6 m,
In this case, the interval l 3 between the outer circumference detection area 11 and the interval l 4 between the inner circumference detection areas 12 on the floor surface are respectively about l 3 = 1.5 m and l 4 =
It is about 1m. Also, the outer periphery detection area 11 on the floor surface
When the interval l 5 between the inner peripheral sensing region 12 is l 5 = 2.0~2.5m about. The main purpose of this human body detection device is to detect a human body that moves by walking, running, sneaking, etc.
Therefore, even if the interval between the detection areas is larger than the size of the human body, a human body detection output can be generated when the human body crosses one of the detection areas as the human body moves.

体の一部の微小な動きを検知することは困難である。[Problems to be Solved by the Invention] However, for example, when detecting a human body sitting in a conference room, a reception room, or the like, it is impossible to expect the entire human body to move. It becomes necessary to detect minute movements of the parts, arms, hands, and the like. However, in the conventional human body detection device, since the interval between the detection areas is wide,
It is not possible to detect a minute movement of a part of the body as described above. For example, in FIG.
When a target T such as a human body is seated near an intermediate point with the inner circumference detection area 12, it is difficult to detect a minute movement of a part of the human body such as a head, an arm, and a hand. is there.

That is, the sensitivity of the detection for the movement of the human body is reduced.

赤外線検出素子２から出力が得られる。FIG. 2 shows an example of the arrangement of a detection area X and a non-detection area Y by the present apparatus. In the present embodiment, the detection area X and the non-detection area Y are squares of the same size, and are arranged so as to form a checkered pattern alternately. This arrangement is a feature of the present invention. Area S in the circle surrounded by the dotted line
In, if there is a movement of the human body part (the whole or a part of the human body) to be detected, the movement is such that the movement passes through the detection area X and the non-detection area Y alternately. , Will cause a change in the amount of infrared radiation,
An output is obtained from the infrared detecting element 2.

領域の大きさの設定は、以下の方法により行えば良い。In order to obtain a human body detecting device that is sensitive to the movement of a human body part (the whole or a part of the human body) to be detected, it is important to obtain a large output signal from the infrared detecting element for the movement. For that purpose, the amount of infrared rays incident on the infrared detecting element due to the movement of the human body part is large,
The condition is that the spatial change of the incident infrared ray is large, that is, the spatial frequency is high. The size of the detection area that satisfies this condition may be set by the following method.
まず、赤外線検出素子２に入射する赤外線量に注目す

あるとき、赤外線検出素子２に入射する赤外線量Ｐ
（x1,y1）は検知領域ＸとターゲットＴとの重なり合う
部分の面積Txにｒを乗算したものとなる。First, attention is paid to the amount of infrared light incident on the infrared detection element 2. Now, as shown in FIG. 2, a target body T (the whole or a part of the human body) to be detected is set as a target T, and a detection area X of a certain size is arranged at a certain position in the area S. And It is assumed that the target T has a predetermined size, and that the surface of the target T uniformly emits r infrared rays per unit area. When there is a target T at a certain position (x 1 , y 1 ), the amount of infrared light P incident on the infrared detecting element 2
(X 1 , y 1 ) is obtained by multiplying the area Tx of the overlapping portion between the detection area X and the target T by r.
Ｐ（x1,y1）＝Tx×ｒ … 同様にして、領域Ｓ全体の各点の入射赤外線量を求
め、これを入射赤外線量平面Ｐ（x,y）とする。また、
平面Ｐにおける各点の２乗平均σＰは次式で表される。P (x 1 , y 1 ) = Tx × r In the same manner, the amount of incident infrared light at each point in the entire area S is obtained, and this is defined as an incident infrared light amount plane P (x, y). Also,
Mean square sigma P of each point in the plane P is expressed by the following equation.
σＰ＝｛∫∫P2（x,y）dx・dy/s｝1/2 … ただし、ｓは領域Ｓの面積である。σＰが大きくなる
ように、検知領域Ｘの大きさと配置を決めれば良いので
ある。σ P = ｛∫∫P 2 (x, y) dx · dy / s｝ 1/2 where s is the area of the region S. The size and arrangement of the detection area X may be determined so that σ P becomes large.
次に、赤外線検出素子２に入射する赤外線の空間周波
数に注目する。入射赤外線量平面Ｐ（x,y）において、
各点の面微分Ｐ′（x,y）は、 Ｐ′（x,y）＝d2P（x,y）/dx・dy … で表される。Ｐ′（x,y）は入射赤外線量平面Ｐ（x,y）

出が行えるものである。Next, attention is paid to the spatial frequency of the infrared light incident on the infrared detection element 2. In the incident infrared ray plane P (x, y),
The surface differential P ′ (x, y) of each point is represented by P ′ (x, y) = d 2 P (x, y) / dx · dy. P '(x, y) is the incident infrared quantity plane P (x, y)
Represents the magnitude of the change. Therefore, by normalizing with the amplitude of the incident infrared ray amount plane P (x, y), the spatial frequency of the incident infrared ray is obtained. Incident infrared ray plane P (x,
The bias value (average value) B of y) is as follows: B = xP (x, y) dx · dy / s. The amplitude A of the plane P (x, y) is A = [{P (x, y) −B} 2 dx · dy / s] 1/2 . Therefore, the spatial frequency f P of the incident infrared ray is f P = [{P ′ (x, y)} 2 dx · dy / s] 1/2 / A. The infrared detecting element 2 is an element for detecting a change in the amount of infrared light, and no output signal is obtained from the infrared detecting element 2 when a certain amount of infrared light is incident, no matter how large. Therefore, if the size and arrangement of the detection region X are set so that both the incident infrared ray amount σ P and the spatial frequency f P of the incident infrared ray become large, the movement of the human body part (the whole or part of the human body) to be detected can be achieved. The human body can be detected with high sensitivity.

The infrared detecting elements A to D are arranged in a "cross-shaped" shape as shown in the figure, and a space is provided between adjacent elements.
The polarity of each of the infrared detection elements A to D is +,
It is assumed that they are connected so as to be-,-, +. In this case, on the floor surface, as shown in FIG. 4, the detection region X + with the polarity of the +, - detection region X with a polarity of - is formed. At this time, the infrared detecting element 2 at the position (x 1 , y 1 )
Infrared amount P (x 1, y 1) to be incident on the a multiplied by the r in the area Tx + the overlapping portion between the detection region X + and the target T, the detection region X - and overlapping portions of the target T area Tx - is the sum of those obtained by multiplying the -r to.
Ｐ（x1,y1）＝Tx+×ｒ−Tx-×ｒ … 同様にして、領域Ｓ全体の各点の入射赤外線量を求

If the size and arrangement of the detection area are set, the human body can be detected sensitively to the movement of the human body part (the whole or a part of the human body) to be detected.
