The present invention relates to a simulation apparatus for detecting an object using a pyroelectric element for detecting an infrared ray, and more particularly, to detect an optimal position by detecting position information of a perspective region of a human body to be detected before mounting the infrared ray detection apparatus to an air conditioner. It is about a device that can be simulated to run.

In general, an infrared detection device is used in a control device or intrusion alarm device for opening and closing an automatic door. The infrared detection device detects that a target object such as a person enters into a specific detection area.

1 is a view for explaining a method of setting a detection area, and as shown in FIG. And a detectable area is set on the floor 3 in the vicinity thereof. According to this method, it is possible to detect an object to be detected, such as a person 4, entering the diagonal region shown in FIG. As another example, by controlling the sensitivity of the infrared detection device, the range of detection can be limited to a predetermined distance from the infrared detection device. That is, by increasing the sensitivity, the detection area can be extended to the far area. By lowering the sensitivity, the detection area can be limited to the near area.

2 is a view for explaining an infrared object detecting device for an air conditioner and a detection area thereof, and the human body information detecting device for the air conditioner is mainly composed of a light receiving unit 100, a signal processing circuit unit 200, and a microcomputer 300. As shown in FIG.

The light receiving unit 100 has two Fresnel lenses 101 and 101 'formed in a hemispherical shape on the printed circuit board 102 at regular intervals so as to have a constant light incident angle. And a partial masking or a light shielding tape 103 is attached as the light shielding means between the Fresnel lenses 101 and 101 'so that the light receiving field intersects in a predetermined detection area.

Therefore, there are substantially three detection regions, that is, three detection regions divided into a first detection region A, a second detection region B, and a third detection region C, as shown in FIG. At the same time, it is possible to divide the detection linear distance from the detection unit into three parts of a long distance, a medium distance, and a short distance. A chip composed of pyroelectric detection elements 104 and 104 'is formed on the Fresnel lenses 101 and 101'. It is formed by mounting.

FIG. 3 is a block diagram showing the detailed configuration of the signal processing circuit unit 200 of the infrared object detection apparatus for the air conditioner shown in FIG. 2, and the signal processing circuit unit 200 shows each pyroelectric detection as shown in FIG. An amplifier 201 and a comparator 202 are sequentially connected to the elements 104, 104 ′, the comparator 202 connected to a microprocessor 300, the amplifier 201 and the comparator 202. It consists of an A / D converter 203 in between.

An example of the case where the infrared object detection device configured as described above is applied to an air conditioner will be described as follows.

If the human body is detected in the first detection area A, the change in temperature sensed by the pyroelectric detecting element 104 is converted into an electrical signal required by the signal processing unit 200, and the charge is detected in the pyroelectric detecting element 104. A voltage is generated at the gate of the impedance converter to amplify the output voltage. At this time, all signals except the set frequency band are filtered while passing through the amplifier 201, and the filtered microsignal is converted into an analog signal having an amplified output waveform as shown in FIG. The signal corresponding to the signal level corresponding to the long distance, the middle distance and the short distance having the voltage level as shown in FIG. 3 (d) is generated according to the distance region divided into three stages. This signal is inputted to the A / D converter 203 and converted to a digital value, and then detected by any one of the first detection area A, the second detection area B, and the third detection area C in the microprocessor. To determine if the According to the determination result, the fan rotation speed of the air conditioner is set in three stages to output a command for controlling the operation of the air conditioner according to the number of people and the moving activity.

(B) of FIG. 4 is a graph showing the A / D conversion function, and (c) is a diagram showing a reference value setting range for the distance area.

In the infrared detection device described above, in accordance with the information of the position area of the object's perspective area through the infrared detection element, it is troublesome to attach it to the actual air conditioner in order to test whether the air conditioner can be operated at the optimum output state. There is this.
