Among the lighting devices that have received the disaster mode command, the LED lighting devices 5, 6, 7, 11, 12, and 13 installed in the parking areas 140 and 150 of the underground parking lot start to operate in the disaster mode and are illuminated. Turn off or low light, and the lighting equipment installed in the passages 160, 170, 180 of the underground parking lot starts the operation in the disaster mode to maximize the lighting (S320).

Figure 4 shows an example of controlling the brightness of each lighting device (410, 420, 430, 440, 450) of the LED system light 400 using a wireless multi-function switch. Referring to FIG. 4, the LED illuminator 410 represents 20% illuminance of the maximum brightness at the minimum brightness, the LED illuminator 420 represents 50% illuminance of the maximum brightness at the intermediate value between the maximum brightness and the minimum brightness. The lighting device 430 shows the illuminance of the maximum brightness (100%).

(Step S330)

FIG. 6 illustrates a time slot in which LED lighting apparatuses in a lighting group sequentially flash during sections during a disaster guidance section. Referring to FIG. 7, assuming that there is an illumination group consisting of five LED luminaires, the first LED luminaire is turned on and off for 1 second at a time T + 1 sec. The second LED luminaire turns on for 1 second at time T + 2 sec and then turns off. The third LED luminaire illuminates for 1 second at time T + 3 sec and then turns off. In this way, the LED lighting devices in the lighting group are wiped out sequentially. This sequential flashing is repeated during the disaster guidance section if the disaster continues.

Synchronization with respect to the time point at which the sequential flashing of these LED lighting devices starts may be performed by the wireless multifunction switch. If the wireless multi-function switch is responsible for the synchronization control of the start point of the flashing can reduce the burden on the control of the central control system, it is possible to prevent the collision of signals. The wireless multi-function switch sets the logical distance value between the address and control sequence of the LED lighting device blinking in the disaster mode and the direction of the emergency exit, so that the LED lighting device is sequentially flashed for guiding the evacuation route based on the reception of the disaster mode command. Can be synchronized in advance.

The wireless multi-function switch may control the lighting devices in the lighting group to blink at a time when the lighting devices installed in the passage are set to a plurality of lighting groups when the disaster mode command is received. Figure 7 shows a timing diagram of the lighting of the entire LED luminaire flashes during the disaster guidance section. Referring to FIG. 7, the LED luminaires are turned on for 1 second at a time T + 1 sec, and turned off for 1 second at T + 2sec, which is 1 second later. By repeating the lighting and turning off during the disaster guidance section every 1 second, it is possible to inform the disaster situation and evacuate.

On the other hand, when the disaster is finished, that is, when the disaster situation is released (step S340), the central control system wirelessly issued a disaster release mode command a plurality of LED lighting devices (1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16) (step S350).

When multiple LED luminaires (1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16) receive the disaster relief mode command, the original auto Return to the control mode (step S360).

8 illustrates an example of a lighting control flowchart according to time for guiding an evacuation route in the underground parking lot shown in FIG. 1 in the method for controlling an underground parking lot using the IOT network according to an embodiment of the present invention. Referring to FIG. 8, a disaster mode command is first broadcast to the wireless multifunction switch and the LED lighting devices. (802) The LED lighting devices 5, 6, 7, 11, 12, and 13 in the parking area Upon receipt of the disaster mode command, the light is controlled to be either unlit or low light brightness (804). At the same time, the LED lighting devices (1, 2, 3, 4, 8, 9, 10, 14, 15, 16) in the passage Change the brightness of the illumination to the maximum (100%). (806) Then, the wireless multifunction switch A 110 near the emergency exit starts controlling the starting point of the flashing of the LED luminaires 9, 8, 3, 2 and 1. (808) First, the blinking of the LED luminaire 9 farthest from the emergency exit among the path lights controlled by the wireless multifunction switch A 110 is controlled. The flashing is controlled (812). Thus, the flashing of the LED lighting device 3, the LED lighting device 2, and the LED lighting device 1 is sequentially controlled. (814, 816, 818).

When the sequential flashing control of the wireless multi-function switch A (110) ends, the wireless multi-function switch B (120) located farther from the emergency exit than the wireless multi-function switch A (110) LED lighting equipment (15, 14, 4, Flashing 3, 2, 1) is controlled sequentially. (820)

As described above, the evacuation route is guided through the sequential blinking of the LED lighting device, and when the disaster situation is terminated, the disaster release mode command is broadcast. (822) Parking area light receiving the disaster release mode command (5, 6, 7, 11, 12, 13 and the luminaires 1, 2, 3, 4, 8, 10, 14, 15 and 16 return to the previous automatic control modes (824, 826).

Emergency disaster evacuation training is also possible through the wireless multi-function switch (110, 120, 130). That is, when the user presses the emergency evacuation training input button and receives the emergency evacuation training instruction for the wireless multifunction switch (110, 120, 130), the flashing mode control for controlling the LED lighting devices to flash during normal time is performed for a predetermined time. Disaster evacuation drills are also available.

9 is a flowchart illustrating an operation example of the wireless multifunction switch used in the underground parking lot lighting control method using the IOT network according to the present invention. Referring to FIG. 9, the wireless multifunction switch 110, 120, 130 may receive a disaster mode command through a key input. If there is a key input (step S910), the LED lighting apparatuses perform sequential flashing control (step S915). When the disaster situation ends, the LED lighting apparatuses perform the disaster release mode. If there is no key input, after checking whether it is in disaster mode control (step S925), delaying the start and turn off time according to the distance setting value to the emergency exit (step S930), and performing flashing control in the set lighting order. (Step S935)

If it is not the disaster mode control in step S925, the wireless multifunction switch may check whether the setting for the flashing control of the LED lighting equipment is necessary (step S940), and update the setting information (step S945). For example, the wireless multifunction switch Is movable, and after entering the light setting function of the LED lighting device flashing in the disaster mode, it is possible to reduce the communication distance by adjusting the radio wave transmission and reception strength (RSSI). When the communication distance is determined as described above, the peripheral lighting device within the distance is searched for and using the address of the LED lighting device having the largest RSSI intensity, the lighting of the lighting device having the greatest RSSI intensity blinks to confirm the blinking control. And press the button to save the setting. And after checking the blinking control of the desired LED lighting device while moving, and save the setting state, if you save all the lighting devices in the order in order to complete the lighting setting by pressing the complete light setting button.

10 is a flowchart illustrating an example of the operation of the LED lighting devices (1, 2, 3, 4, 8, 9, 10, 14, 15, 16) located in the passage in the underground parking lot lighting control method using the IOT network according to the present invention It is represented as. Referring to FIG. 10, when the LED lighting devices 1, 2, 3, 4, 8, 9, 10, 14, 15, and 16 located in the passage receive a disaster mode command (step S1010), the flashing control is started. do. When the LED lighting devices (1, 2, 3, 4, 8, 9, 10, 14, 15, 16) located in the aisle receive a disaster release command (step S1030), Return to the control mode (step S1040) When the LED lighting devices (1, 2, 3, 4, 8, 9, 10, 14, 15, 16) located in the passage receives a control or setting input (step S1050). Update the mode information or the setting information (step S1060).

11 is a flowchart illustrating a light control method for an underground parking lot using an IOT network according to another embodiment of the present invention.

1 and 11, when a disaster alert occurs, the central control system (not shown) wirelessly sends a disaster mode command to the plurality of LED lighting devices 1 to 16 and the wireless multifunction switches 110, 120, and 130. Broadcast to the user (step 1110).

Among the lighting devices that have received the disaster mode command, the LED lighting devices 5, 6, 7, 11, 12, and 13 installed in the parking areas 140 and 150 of the underground parking lot start to operate in the disaster mode to turn on the lights. The lights are turned off or low light, and the lighting devices installed in the passages 160, 170, and 180 of the underground parking lot start to operate in a disaster mode so as to maximize the lighting (S1120).

The wireless multifunction switches 110, 120, and 130 installed in the passages 160, 170, and 180 receive the disaster mode command, and the lighting devices 1, 2, 3, and 4 installed in the passages 160, 170, and 180. , 8, 9, 10, 14, 15, 16 to control the start timing of flashing, based on the distance to the emergency exit (not shown) of the underground parking lot 100 in a predetermined order by a predetermined time (t) in order Control to guide the evacuation route by starting to flash with (S1130).

The central control system is a wireless multi-function if the motion is not detected by a motion sensor (not shown) installed in the LED lighting devices (1 to 16) (step S1140), the motion detection frequency information on the lighting control timing of the LED lighting device And transmits to the switches 110 and 120 (step S1150). The wireless multifunction switches 110 and 120 receive the motion detection frequency information of the LED lighting apparatuses, and the blinking of the LED lighting apparatuses having the small frequency of the motion sensing by the motion sensor are blinked. For example, if there is a fire, LED lighting devices with a low frequency of motion detection are regarded as a case where the smoke is not detected due to the heavy smoke due to the fire. The motion detection frequency information is broadcast at the lighting timing, and the wireless multifunction switches 110 and 120 receive the motion detection frequency information so that the motion detection frequency is low. By the faster flash cycle, and to provide evacuation routes more reliably. In other words, the flashing period of the LED lighting device is also added as a parameter so that it flashes a little slower, and when the frequency of motion detection by the motion sensor decreases, the flashing period becomes faster.

12 is a flowchart illustrating a method for controlling light of an underground parking lot using an IOT network according to another embodiment of the present invention.

1 and 12, when a disaster alert occurs, a central control system (not shown) wirelessly sends a disaster mode command to a plurality of LED lighting devices 1 to 16 and wireless multifunction switches 110, 120, and 130. Broadcast to the user (step 1210).

Among the lighting devices that have received the disaster mode command, the LED lighting devices 5, 6, 7, 11, 12, and 13 installed in the parking areas 140 and 150 of the underground parking lot start to operate in the disaster mode to turn on the lights. The lights are turned off or low light, and the lighting devices installed in the passages 160, 170, and 180 of the underground parking lot start to operate in a disaster mode to brighten the light to the maximum (step S1220).

The wireless multifunction switches 110, 120, and 130 installed in the passages 160, 170, and 180 receive the disaster mode command, and the lighting devices 1, 2, 3, and 4 installed in the passages 160, 170, and 180. , 8, 9, 10, 14, 15, 16 controls the start timing of the flashing. In this case, the wireless multi-function switch may be separately allocated to the lighting devices in the passage for each lighting group. For example, the LED lighting equipment (1, 2, 3, 8, 9, 10) belongs to the first lighting group, the first lighting group is assigned a wireless multifunction switch A (110), the lighting equipment (1 , 2, 3, 4, 14, 15, and 16 may belong to the second lighting group, and the second lighting group may be assigned the wireless multifunction switch B 120. In addition, a wireless multifunction switch C 130 may be separately installed near the emergency exit.

As an example, the wireless multifunction switch A 110 may delay the LED lighting apparatuses belonging to the first lighting group by delaying the predetermined time t in a predetermined order based on the distance to the emergency exit (not shown) of the underground parking lot 100. Control to guide the evacuation path by (10, 9, 8, 3, 2, 1) to start flashing sequentially. In addition, the wireless multi-function switch B (110) is delayed by a predetermined time (t) in a predetermined order based on the distance to the emergency exit (not shown) of the underground parking lot 100 LED lighting devices 16, belonging to the second lighting group (16, 15, 14, 4, 3, 2, 1) to start the flashing sequentially to control to guide the evacuation route (step S1230).

The central control system receives the motion detection frequency information by the motion detection sensor for each lighting group (step S1240). The central control system allocates the motion detection frequency information for each lighting group to the lighting control timing of the LED lighting device. Transmit to the wireless multi-function switch (step S1250).

The wireless multifunction switches 110 and 120 assigned to each lighting group receive the motion detection frequency information and wirelessly communicate with each other to determine the priority of the flashing start timing so that the wireless multifunction switch assigned to the lighting group having the high motion detection frequency is LED. Start flashing of the lighting device first to guide the evacuation route and transfer the priority to the wireless multifunction switch of the next priority to start the flashing of the LED lighting device (step S1260).

For example, when the detection frequency of the first lighting group is high, the priority function of the flashing start timing is given to the wireless multifunction switch A 110, and the LED lighting devices 1, 2, 3, 8, 9, 10 to guide the evacuation route, and then the wireless multi-function switch B (120) to give priority to the flashing start timing LED lighting devices (1, 2, 3, belonging to the second lighting group) Flashing control of 4, 14, 15, 16) can be used to guide the evacuation route. The priority of the wireless multifunction switches may vary in time or number of times.

On the other hand, the present invention, when the power is not supplied due to the fire of the building, that is, when the LED lighting devices belonging to the lighting group can no longer blink, the wireless multi-function switch 110 equipped with a battery and emergency lights (110) , 20, 130) can be flickered with the battery as an emergency power source. For example, when the LED luminaires belonging to the lighting group can no longer blink, the wireless multifunction switches 110, 20, and 130 are wirelessly multifunction switches B 120 farthest from the emergency exit through wireless communication with each other.
