The present invention relates to an intelligent security lamp control device, and more specifically, self-learning the intensity of illumination that varies with the surrounding environment and the seasons. Lights) are turned on / off.

In general, indoor lighting is used for indoor lighting.In case of temporary or long-term emptying of the house due to vacation or going out (absence), the indoor lighting is turned on at night to disguise as if there is a person. have.

In the method of turning on / off the security lamp (indoor lamp), the time control method using a timer and the illumination control method according to the ambient brightness are used. In the case of the time control method using a timer, the sunrise time and the sunset time vary depending on the season, and the surrounding environment. In some cases, there is a big difference in illuminance, so it is cumbersome to reset the turn-off and turn off lights every time you use them.

In addition, in the simple illuminance control method, since the light is turned on and off according to the ambient light, there is no need to set the turn on / off time every time, but the unexpected bright light amount on the illuminance recognition means (illumination sensor), for example, When a light source such as a headlamp light or a street lamp, fixed and flexible reflected light, and moonlight is irradiated, there is a problem that the security lamp malfunctions and the security effect is lost or the effect is halved.

In addition, there are many daily illuminance differences between high-rise buildings, such as apartments, and low-rise buildings, such as single-family homes. In addition, there is a problem that the illuminance difference also occurs depending on the inflow, inflow, inflow angle, and the like of external light sources such as moonlight and streetlights, and the conventional method cannot cope with such unexpected environmental changes, thereby achieving the desired security purpose. In addition, in the case of the general public, there is a problem such that it is not easy to adjust the amount of illumination detection according to the installation environment.

In order to solve the above problems, the present invention allows the security lamp to be turned on / off in an optimal state according to the ambient light, but the self-learning at various times according to the environment and the season is self-learning. An object of the present invention is to provide an intelligent crime prevention light control device that is ON / OFF in detail, according to the accompanying drawings, preferred embodiments of the present invention as follows.

Attached FIG. 1 is a circuit block diagram of an embodiment of the present invention, and includes an illumination intensity sensing unit 10 for sensing an ambient illuminance or a light intensity and analyzing the detected illuminance value to determine the maximum illuminance, the minimum illuminance, and the average illuminance. A CPU (central processing unit) that learns the slope change of illuminance for each time to obtain an average illuminance, and then outputs a control signal at an optimum (appropriate) time; and a storage unit 20 that stores illuminance data by self-learning; When the control signal is output from the CPU, the output unit 40 for turning on / off the security target lamp 30 and the lamp 30 are turned on and off manually by pressing the lamp 30 continuously for 2 seconds or more, and the state is changed to the security state. When pressed once more in the crime state, the switch unit 50 is reduced to the manual on / off state, the sound display unit 60 which generates a confirmation sound when the crime state or the crime state is released, and the CPU for Consisting of the oscillation unit 70 and the power supply unit 80 A.

The sound display unit 60 is composed of a piezoelectric-loud speaker or a buzzer, and when it is switched to the crime prevention state, the sound is displayed several times by the sound display unit 60, and the alarm is released once when the crime state is released. Make the status easier to recognize.

In the above, the illuminance sensing unit 10 generally uses photoconductive cells such as photoconductive cells (cds), photodiodes, and phototransistors that can detect visible light, and the detected illuminance values are analog signals. In this case, the A / D converter (not shown) is connected between the photosensor and the CPU so that the CPU can recognize the input illuminance signal.

The memory IC used for the memory 20 is preferably an E ² PROM (electrically rewritable PROM), but a RAM such as a RAM may be used to store a rechargeable battery. It is also possible to connect or configure a rechargeable capacitor for the purpose of storage such as RAM.

In the above, the switch unit 50 for turning on and off the light 30 is installed on the wall surface of the room for crime prevention, and the illuminance detection unit 10 is installed on the switch unit 50 to illuminate the room for crime prevention. To be detected.

In addition, in the crime prevention state, the CPU will turn on the lamp 30 at a suitable time with illumination data by self-learning, but turn off the lamp 30 to output a light-off signal after a few hours of bedtime.

The bedtime can also obtain a suitable light off time by self-learning the illumination input all day, the light off time may vary somewhat depending on the summer or winter when the daylight intensity (日照 度) difference is significant, but 5 to 7 hours after lighting It is desirable to turn off the light when elapsed.

On the other hand, when the illuminance at the start of the security function is called the anti-illumination which is the reference for the control of the light 30, when the power is applied by installing the anti-illumination control device, the illuminance detection unit 10 continuously inputs the illuminance of the room. Received and stored in the memory unit 20 (ignore the illumination data when the light is on), and analyzes the input illuminance after about a day, but analyzes the change in the slope of the maximum illuminance, minimum illuminance, average illuminance and hourly illuminance Self-learning to obtain standardized security illuminance data.

If the above-described illuminance (the crime prevention illuminance for the room) and the crime prevention illuminance already stored in the memory unit 20 are reset to the formula of new crime illuminance = (remembered crime illuminance × 2 + analyzed illuminance) ÷ 3 As one-third of the deviations are approached on a daily basis, crime prevention illuminance according to environmental changes is applied in a short period to suit the room.

For example, assuming that the standard security illuminance is 100 lux (lx) when the control device is shipped, the process of learning change of the standard security illuminance in a dark room is shown in Table 1 and FIG. 1 below.

In addition, looking at the learning change process of the standard security illuminance in a bright room for another embodiment as shown in Table 2 and 2 below.

In the above two embodiments, the rapid change in illuminance changed within about 10 days is adapted to self-learning, thereby turning on the lamp 30 by approaching 1/3 or 1/4 of the daily unit deviation, and depending on the self-learning result after the lighting. When the off time is changed (about 5 hours to 7 hours), the extinguished signal is output to the output unit 40 to turn off the lamp 30.

In the case of shortening the application time of crime prevention, the formula of new crime intensity = (remembered crime intensity x 2 + analyzed illumination) ÷ 3 is set to new crime intensity = (memorized crime intensity + analyzed illumination) ÷ 2 If you adjust the adaptation time to new security illuminance = (remembered security illuminance × 3 + analyzed illuminance) ÷ 4, it turns on by approaching 1/4 of daily deviation. Could be.

In the above, when the crime application time is shortened, the deviation approaching the security illuminance is approached by 1/3, and when the crime application time is extended, the deviation approaching the security illuminance is approached by 1/4, Only one embodiment, the deviation approaching according to the crime prevention illuminance can be set flexibly according to the situation.

The reason why the deviation is applied without applying 100% of the standard crime prevention intensity analyzed in the above is that there is a high possibility of malfunction due to the uniqueness. Here, the singularity may include a case where an abnormal form of contrast is applied, such as when an obstacle having a light shielding effect is located in the illuminance detection unit or when the lamp 30 is turned on overnight.

In this case, if the value of the analyzed illuminance is very large compared to the value of the illuminance analyzed the previous day (when it is out of 50 lx-150 lx based on Tables 1 and 2), the analyzed illuminance is ignored. Affects.

The present invention has been configured in this way, the manual operation of the switch unit 50 as in the prior art to use the ON / OFF the light 30 to temporarily or long-term need to empty the house, if you want to use in a crime prevention state switch unit ( If 50) is pressed for 2 seconds or more, the lamp 30 is turned on or off while maintaining the ON or OFF state, and the confirmation display 60 outputs several confirmation sounds to indicate that the crime is in the state.

In this state, the illuminance of the interior of the crime prevention target object is input to the CPU through the illuminance detection unit 10 and then stored in the storage unit 20.

On the other hand, the illuminance data stored in the storage unit 20 is analyzed by the daily illuminance as described above to obtain a new crime prevention illuminance, the lamp 30 is lit according to the new crime prevention illuminance is crime prevention. In addition, the present invention has no hassle of setting the operating illuminance every time since the security target lamp 30 is turned on by the illumination illuminance learned according to the surrounding environment and the season.

As described above, the present invention self-learning the ambient light, the security lamp is turned on at the optimum time to prevent malfunction, and the desired security effect is achieved.
