The present invention relates to a sterilization system, and more particularly, to sterilize an open indoor space through a sterilization lighting unit having a UV light source, and to control the sterilization lighting unit to safely operate according to detection information from a motion sensor and a heat sensor. It relates to a smart sterilization system for indoor spaces that can be used.

In general, most sterilizer products on the market utilize the UV-C wavelength band known as the sterilization line among UV-A, UV-B, and UV-C, and 256.7, which is known to have the most excellent sterilization power among UV-C nm is used a lot.

However, as a functional limitation of UV-C, as UV-C belongs to a short wavelength among ultraviolet wavelengths, the scattering rate in air is high and the effective irradiation distance is short.

As a result, ultraviolet rays cannot pass through thin glass or fiber and are scattered in the air, so most UV-C sterilizers have a disadvantage that the effective irradiation distance is only about 30 cm. It is difficult to use C.

Accordingly, there is a growing demand for an open space sterilization system that overcomes the irrationality of the conventional ultraviolet UV-C sterilizer and utilizes UV-A to sterilize various objects in an open space.

Subsequently, the sterilization lighting control unit 350 generates a predetermined control signal SC to control the operation of the sterilization lighting unit 100, and transmits the operation time t1 set by the user or the like from the operation time setting unit 370. In response, the sterilizing lighting unit 100 is turned on, or the sterilizing lighting unit 100 is turned on or off according to the determination (D1 or D2) of the absence determination unit 330.

Subsequently, the operation time setting unit 370 receives the operating time t1 of the sterilization lighting unit 100 from the user and transmits it to the sterilization lighting control unit 350, or the operation resume time of the sterilization lighting unit 100 ( t2) is received and transmitted to the absence determination unit 330.

Hereinafter, a method for the control unit 300 to control the sterilization lighting unit 100 will be described in detail.

First, the sterilizing lighting control unit 350 turns on the sterilizing lighting unit 100 so that the sterilizing lighting unit 100 operates for a predetermined operating time t1 according to the operating time t1 input by the user or the like.

At this time, when the movement of the object in the indoor space is detected by the motion sensor 210 of the sensing unit 200, the absence determination unit 330 determines whether the object is located in the indoor space according to the motion detection information i-1. It is determined that it exists (D1), and the sterilizing lighting control unit 350 turns off the sterilizing lighting unit 100 according to the determination (D1) of the absence determination unit 330 so that the sterilizing lighting unit 100 does not operate.

On the other hand, it is determined (D1) that an object exists in the indoor space according to the motion detection information (i-1) during the preset operating time (t1) and the operation of the sterilization lighting unit 100 is turned off, and the preset operation resumes. If the movement of the object is not detected for more than the time t2, the absence determination unit 330 may determine that the object does not exist in the indoor space (D2), and the sterilization lighting control unit 350 may determine the absence determination unit ( According to the judgment (D2) of 330), the sterilization lighting unit 100 can be turned on to operate again.

Here, as described above, the sensing information (i) may include motion sensing information (i-1) for the motion of the object and heat sensing information (i-2) for the body temperature of the object, and the absence determination unit ( 330) determines that an object exists in the indoor space when the body temperature of the object is sensed according to the heat detection information (i-2) even though the movement of the object is not detected according to the motion detection information (i-1) (D1) And, the sterilization lighting control unit 350 is characterized in that the operation of the sterilization lighting unit 100 is turned off according to the determination (D1) of the absence determination unit 330.

That is, the absence determination unit 330 detects motion when the motion of an object in the indoor space is detected according to the motion detection information i-1 when the sterilization lighting unit 100 is operating during the operating time t1. It is determined (D1) that an object exists in the indoor space through only information (i-1), but when the sterilization lighting unit 100 is not operating during the operating time (t1), motion detection information (i-1) and heat detection The existence of the object in the indoor space is determined using the information (i-2).

During the preset operation time (t1), it is determined (D1) that an object exists in the indoor space according to the motion detection information (i-1) and the operation of the sterilization lighting unit 100 is turned off, and the object in the indoor space moves This is because the movement of the object in the indoor space may not be detected.

Accordingly, the sensing unit 200 of the present invention operates only the motion detection sensor 210 to detect the movement of the object in the indoor space when the sterilization lighting unit 100 is operating during the preset operating time t1.
