[Example]

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

FIG. 1 is a perspective view showing the arrangement of a device according to the present invention.

The present invention is applied to an apparatus for on / off control of each illumination light 15 installed in a plurality of independent spaces having respective doors in a house or an office. The infrared sensors 11, 12, A microphone 14, a selection switch 16, a microcomputer controller 10, and the like.

At this time, the infrared sensors 11 and 12 according to the present invention are installed on the wall in the upward direction of the door, and generate an analog signal according to a human approach.

The infrared sensors 11 and 12 are means for detecting infrared light caused by human body temperature, and can be classified into a proton type and a thermal type, and the latter ones are preferably used. The quantum form of a semiconductor substrate has a better response speed than a thermal type, but has a limitation of sensitivity to wavelength selectivity, while a thermal type has a flat sensitivity in a wide wavelength range and is suitable for use at room temperature.

These infrared sensors 11 and 12 are formed of a pair of the same functions that are installed separately on the inside and the outside of the door. Since the present invention is a method of counting the entrance and exit of a person, each infrared sensor 11 and 12 is formed as a pair, and a predetermined signal is detected in both sensors to be counted. In this way, the sensor can be counted if the sensor is accessed but no human is in or out.

In addition, the optical sensor 13 according to the present invention is installed toward the outside such as a window in a room, and generates an analog signal according to the amount of external light. The photosensor 13 uses a cadmium sulfide sensor (CdS) or the like whose internal resistance value changes according to the amount of light, and is installed at a place where an external light quantity is inputted to easily recognize the day and night.

Further, the microphone 14 according to the present invention is installed in the vicinity of the illumination lamp 15, and generates an analog signal according to a change in volume. The microphone 14 is a means for converting sound into an electrical signal and can form a current or voltage signal proportional to a change in sound pressure. It is preferable that the microphone 14 is installed at the center of the room such as the illumination lamp 15 in consideration of the accuracy of judgment of whether the person is staying in a specific space or in a static state (e.g., a sleeping state).

Further, the selection switch 16 according to the present invention has three modes of on, auto, and off, and the state is changed manually by the user. The on-off mode is for manually operating the illumination lamp 15 as in the prior art regardless of the object of the present invention, and the automatic mode is for exerting a function meeting the object of the present invention.

The microcomputer controller 10 according to the present invention has its own memory, an A / D converter, a counter unit, a driving unit and the like. The infrared sensor 11, the optical sensor 13, the microphone 14, And determines whether or not there is a person and turns on / off the illumination lamp 15. [ The microcomputer controller 10 is a microcomputer having a main function unit such as a CPU, a memory, an input / output interface, and the like. It is sufficient to use an 8-bit microcomputer for executing the algorithm according to the present invention.

FIG. 2 is a block diagram showing the wiring state inside the microcomputer controller of FIG.

The microcomputer controller 10 has an A / D converter, a counter unit, a driving unit, and the like outside the main function described above. There is also a constant voltage circuit for rectifying the AC power source of the home and supplying the power of 5V stably though it is not shown in the drawing, and a charging circuit for maintaining continuity of operation even during power failure. Infrared sensors 11, 12, a photosensor 13, a microphone 14, and the like are connected to the input side of the microcomputer controller 10, and the respective illumination lamps 15 are connected to the output side.

The A / D converter digitizes the input from the infrared sensors 11 and 12, the optical sensor 13 and the microphone 14, and the input from the microphone 14 is input to a filter unit (not shown) (Not shown) and processed in the A / D converter. It is preferable that the filter section and the amplifying section have a large sensitivity in a frequency band corresponding to a human voice. If the output of the A / D converter is used only as an object to be compared with a predetermined reference value by the microcomputer, it is also possible to use a comparison circuit (not shown) constituted by an OP amplifier by omitting the A / D converter.

The counter unit is a count timer circuit for counting the number of people in the room or calculating the operation time of the illumination lamp 15. [

The driving unit uses a relay or a power transistor as a switching circuit for connecting the household AC power source to the illumination lamp 15 as an output of the microcomputer.

Although the connection state of the selection switch 16 (FIG. 1) for distinguishing between the automatic mode and the manual mode and the microcomputer controller 10 is not shown, the microcomputer controller 10 controls the mode of the selection switch 16 Always counts the number of people in each independent space and stores them in its own memory.

To this end, the microcomputer controller 10 includes a main program for counting and storing the number of people, and a subroutine program for processing all inputs, such as the third mode described later, when the selection switch 16 is in the automatic mode. When the selection switch 16 is in the manual mode, only the main program for processing input from the infrared sensors 11 and 12 is activated.

FIG. 3 is a flowchart showing an operation sequence for an embodiment of the present invention.

First, the main program causes the microcomputer controller 10 to receive input from the infrared sensors 11 and 12 irrespective of the mode of the selection switch 16, so that the infrared sensors 11 and 12 First, it is possible to determine whether a person goes out of a predetermined space according to where the input is detected. For example, in FIG. 1, when there is a person in the room and a new person enters the front door, a signal is detected by the infrared sensor 11 on the outside and then detected by the infrared sensor 11 on the inside. At this time, the microcomputer controller 10 stores 2 persons in the living room. When the person goes out to the entrance, the infrared sensor 11 can detect the signal in the reverse order. The operation principle of the infrared sensor 12 and the microcomputer controller 10 is the same when a person goes into and out of a living room and a room. In this way, the living room and the number of people in each room are stored in the memory and periodically refreshed by the main program.

At this time, if the selection switch 16 is in the automatic mode, the microcomputer controller 10 starts the subroutine program in step ST20.

Receives the input of the optical sensor 13 in step ST21, and compares it with the reference value on the memory in step ST22. Only in the case where it is judged as night at step ST22, the process goes to step ST23 and the data of the counter section to be refreshed by the main program is input.

In step ST24, the number of people in the living room or room is checked, and if there is a person, the input is received from the microphone 14 in step ST25.

If the input of the microphone 14 is checked at a predetermined time interval (for example, 1 minute) for a predetermined time (for example, 30 minutes) in step ST26 and it is determined that the input is equal to or greater than the predetermined value in the memory 1 time, If not, the illumination lamp 15 of the corresponding space is turned off in step ST28. In step ST27, the illumination lamp 15 does not need a time delay, but in step ST28, the timer function of the counter unit is used to delay the predetermined time. That is, it is turned off only when there is no re-input of the microphone 14 even after a predetermined time has elapsed since the last input of the microphone 14. If there is an input of the microphone 14 in the absence of a person, it is judged to be the surrounding noise. It is also possible to operate immediately without such a time delay.

On the other hand, when sleeping, the illumination lamp 15 is automatically turned off after a predetermined time in step ST26 of the subroutine program, and the selection switch 16 is switched to the off mode in order to turn it off earlier.

As described above, the automatic lighting apparatus control apparatus of the present invention recognizes daytime or nighttime, presence of a person, activity area of a person in a house or an office, and automatically turns on / And provides the benefit of power saving.

Although the present invention has been shown and described with respect to certain preferred embodiments thereof, it will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention as set forth in the following claims Those skilled in the art will readily understand the present invention.
