Accordingly, for pixels appearing in the infrared image (first image 6), points that appear at a higher temperature than the average temperature of the surrounding area can be extracted.

A 19th body temperature detection step of calculating 'the number of the 6-1 color codes / the number of the 1-1 color codes = first excess rate'; and a 20th body temperature detection step of calculating 'the number of the 6-2 color codes / the number of the 1-2 color codes = the second excess rate'; in the average temperature of the peripheral area within the first image 6. The first exceedance rate and the second exceedance rate, which are the ratios at which points appear at higher temperatures compared to , are calculated.

21st body temperature detection that turns off the UV lamp when the 'third excess rate that is the sum of the first exceedance rate and the second exceedance rate' is greater than a predetermined standard value, and turns on the UV lamp when the third exceedance rate is less than a predetermined standard value. In step;, it is determined whether to turn off or turn on the UV lamp based on the third excess rate calculated by adding the calculated first excess rate and the second exceedance rate.

If the third exceedance rate is above the standard value, the temperature is calculated to be higher than the surrounding area, so it can be judged that a person is approaching, so turn off the UV lamp. If the third exceedance rate is below the standard value, the temperature is higher than the surrounding area. Since the high ratio is calculated to be low, it can be determined that the situation is not close to people, so the UV lamp can be controlled to turn on.

In the 22nd body temperature detection step of repeating the first to 21st body temperature detection steps at predetermined time intervals, the above-described steps are repeated at predetermined time intervals to continuously prevent situations in which people are close to or away from each other. You can recognize/judge and control the turning on/off of the UV lamp.

According to the steps described above, whether or not a person is detected is not simply determined based on what the surface temperature is, so when the person is wearing clothes, when the person's hair is photographed, and at the angle at which the person is photographed. It is possible to determine whether a person is approaching with high accuracy regardless of variables such as data processing based on only some pixels of the first image 6, and no calculation processing using artificial intelligence models, etc., so low performance. It can be performed/processed quickly by CPU/Micom/control unit.

In addition, a second coil unit is spaced apart from each of the plurality of first coil units 4 by a predetermined distance and is disposed in the first accommodation space, and is connected to the control unit, and the control unit: 1 A first monitoring step (S100) of detecting current from the coil unit (4); A second monitoring step (S200) of applying alternating current power to a third coil portion of the first coil portion 4, the current of which is detected in the monitoring step; A third monitoring step (S300) of detecting current from each of the second coil units; A fourth monitoring step (S400) of continuously supplying or blocking AC power to the third coil unit based on the current detected by the second coil unit; and a fifth monitoring step (S500) of repeating the third monitoring step (S300) and the fourth monitoring step (S400) at predetermined time intervals. ) Configured to supply alternating current power to the third coil unit on which a predetermined magnetic object is seated in the middle and upper parts, and determine whether the magnetic object is a wireless charging object based on the current detected in the second coil unit.

In this case, the object placed on the third coil unit is deemed not to be a mobile device (charging object) and the AC power supplied to the third coil unit can be cut off.

The above reference value is a value determined through previous experiment/measurement, and can be stored in the non-transitory storage medium of the control unit.

A fifth monitoring step (S500) of repeating the third monitoring step (S300) and the fourth monitoring step (S400) at predetermined time intervals is to check whether the object mounted on the third coil unit is charged at a certain time. By repeating every hour, it is possible to prevent charging from continuing after charging is completed.
