Hereinafter, a control method of the monitoring apparatus according to the present embodiment will be described in more detail with reference to the drawings.

4 is a flowchart illustrating a control method of a monitoring apparatus according to an embodiment of the present invention.

Referring to FIG. 4, in the control method according to the present exemplary embodiment, the sensor 15 arranged in the lighting apparatus 10 waits to detect an object (S10), and detects the object through the sensor 15. (S20), determining the movement of the object when the object is detected (S30), determining the movement direction of the object when the movement of the object is determined (S40), and the object Lighting the illumination 12 in the moving direction of the step S50, and after determining the moving direction of the object, rotating the camera device 30 so that the subject of the object may be obtained (S60). do.

The step S20 is a step of sensing an object through the sensor 15. After the sensor 15 disposed above the object transmits a sensing signal toward the object, the S15 detects a reflection signal.

The step S30 is to determine the movement of the object, so as not to recognize the stopped vehicles as the object as in a parking lot. That is, to determine this when the moving car is stopped or parked, the control module 50 of the lighting device 10 determines that the car is moved when the time difference of the signal reflected from the sensor 15 occurs. The moving speed of the object may be calculated using the time difference of the reflected signal.

Thus, when the object is stopped, there is no change in the distance of the signal received through the sensor 15, and the stopped object may be determined by receiving the reflected signal at predetermined time intervals.

The control module 50 transmits the signal and the calculated data detected through the sensor 15 to the server 20 through the communication module 16.

The step S40 is for determining the moving direction of the object, and determines the moving direction of the object through the data received from each lighting device 10.

Here, the signals and data detected by the respective lighting devices 10 are transmitted to the server 20, and the server 20 determines the moving direction of the object based on the transmitted signals and data. That is, when data generated when the object is continuously moved from a plurality of adjacent lighting devices 10 is transmitted, the server 20 not only determines the movement of the object through this, but also between the respective lighting devices 10. The direction of movement of the object may be determined by determining the arrangement.

In addition, when a sensing distance of an object is increased in one of the lighting devices 10 and a series of data in which the sensing distance of the object is reduced in the adjacent lighting device 10 is received, the determination is made to determine the direction of movement of the object. You can also make an accurate decision.

In addition, the server 20 lights the light 12 positioned in the moving direction of the object after determining the moving direction of the object so that the amount of light is effectively increased only when the object is moved. (S50)

In addition, the server 20 rotates the camera device 30 to the side where the movement of the object is sensed, and gradually rotates the camera device 30 in accordance with the moving direction of the object, thereby making the object more clear. (S60)

5 is a flowchart illustrating a control method of a lighting apparatus according to an embodiment of the present invention.

Referring to FIG. 5, the control method according to the present exemplary embodiment includes lighting the lighting 12 to a minimum amount of light through the control unit 58 (S110), and waiting for sensing an object through the sensor 15. (S120), determining the movement of the object through the sensor 15 (S130), and when the movement of the object is determined by the controller 58, the illumination control unit 52 to increase the illuminance. Controlling the lighting 12 with the set illuminance by controlling (S140), calculating the use time of the lighting 12 when it is determined that the object is not moved by the controller 58, and 150 The controller 58 calculates the amount of power based on the signal sensed by the amount of power monitoring unit 56 (S160).

The step S110 is a step of lighting at least one light 12 in the lighting device 10 in which a plurality of lights 12 are arranged, such as a fluorescent lamp.

Herein, the control unit 58 does not continuously light only a constant fluorescent lamp among the plurality of fluorescent lamps, and controls the plurality of fluorescent lamps to be turned on at the same use time by the illumination control unit 52 so as to be disposed in the lighting apparatus 10. The plurality of lamps are kept in the same life.

Thus, the illuminance control unit 52 sequentially turns on the illumination 12 based on a predetermined time so that the minimum amount of light is maintained.

In step S120, the controller 58 waits for sensing an object through the sensor 15.

The step S130 is for determining the movement of the object through the signal detected by the sensor 15, and the same description as in step S30 will be omitted.

In the step S140, when the movement of the object is determined, the controller 58 controls the illuminance controller 52 to adjust the illuminance and the number of lights of the light 12.

Next, after a predetermined time elapses after the step S140, the process returns to the step S130.

On the other hand, when the controller 58 determines that there is no movement of the object in step S130, the use time of the lighting 12 is calculated (S150), or the amount of power used of the lighting 12 is calculated.

Here, the step S130 determines that there is no movement of the object when the signal sensed by the sensor 15 is kept constant for a predetermined time.

In addition, the calculation of the use time of the lighting 12 and the amount of power may be performed by the server 20 or by the controller 58 of the control module 50.

In particular, the end-of-life illumination 12 increases the amount of power used compared to general lighting, so that the end-of-life illumination 12 can be more effectively determined through the power amount monitoring unit 56.

In addition, when it is determined in step S130 that there is no movement of the object, the illumination control unit 52 is controlled to minimize the illuminance and the light amount of the illumination 12 after a predetermined period of time passes (S135).
