Description

FIELD OF THE INVENTION The present invention relates to an illumination control system with built-in sensor for flat panel illumination,

The present invention relates to a sensor built-in illuminance control system such as a flat panel illumination, and more particularly, to a sensor built-in illumination control system such as a flat panel illuminator that has a built-in sensor in a flat panel illumination lamp itself.

As is known, generally, the illuminance sensor is used to compare the illuminance set to control the illuminance of the illuminance and the current illuminance, and the illuminance of the illuminance is increased or decreased by the brightness corresponding to the difference. do. In order to achieve the above object, the present invention provides a method of controlling an illuminance of an illuminating lamp, the illuminance illuminating apparatus comprising: A dimming circuit provided for each zone according to a signal supplied from the apparatus and the central control device, and an illumination lamp connected to the dimming circuit are controlled. For example, Korean Patent Registration No. 1265650 (entitled " (Hereinafter referred to as " cited invention 1 "), which is shown in Fig.

This Reference 1 discloses at least one light emitting device; And a light control remote controller for controlling the light emitting device with a predetermined communication protocol,

Wherein the illumination control remote controller comprises a touch unit to which a gradation of n points x m points is applied for controlling at least one of a color temperature and a dimming of the light emitting device,

And a control unit for generating and outputting a control signal for at least one level control of color temperature and dimming according to at least one point information inputted through the touch unit,

Wherein the control unit generates the control signal based on the first point information on the first touch point and the second point information on the latest touch point among the plurality of point information input through the touch unit and outputs at least one of the color temperature and the dimming level So that one level is controlled.

Accordingly, Reference 1 has an effect of being able to easily control a network-connected lighting device using a remote controller, and secondly, not only can the power source be controlled through the interface of the remote controller, but also the color temperature and dimming can be precisely It is possible to expect the effect that the control can be performed step by step or the like.

 Therefore, such a conventional lighting control system requires many expensive facilities such as a gateway 30, a controller 20, an interface 10, a monitoring panel 80 and the like for controlling illumination of a required area, The cost and construction period are excessive, and a dedicated manpower for management and operation of the system is required. Thus, an economic burden is inevitable.

In addition, in order to prevent frequent changes in the brightness of illumination controlled by instantaneous changes in illumination, the illumination control apparatus, the illumination control system, and the illumination control method (hereinafter referred to as " 2 ') has been proposed, and such Reference 2 is shown in Figs. 2 to 4. Fig.

The second reference numeral 2 is an example for correcting a newly measured illuminance value when an illuminance change occurs (S200), wherein the step of correcting the illuminance value (S200) includes comparing at least one measured illuminance value and a newly measured illuminance A step S210 of calculating a correlation coefficient including a value and a step S220 of correcting a newly measured illumination value based on the calculated correlation coefficient.

That is, it is preferable to correct the new measured illuminance value so that the calculated correlation coefficient including the corrected new measured illuminance value is 0.8 or more.

As described above, Reference 2 can control the noise to be corrected and removed by the step of correcting the new measured illuminance value so as to be stably maintained without frequent changes in the illuminance control for one region through the light emitting means 31 to 43 And the amount of energy consumption generated by frequent illumination control on the light emitting means 31 to 43 can be reduced.

Therefore, the lighting control device, the lighting control system, and the lighting control method according to the second invention have the effect of controlling the light emitting means so as not to react sensitively every time due to the instantaneous change in illumination intensity.

On the other hand, in the case of Reference 2, the reaction rate is insensitized by a predetermined correlation coefficient. Therefore, even when the illuminance greatly increases or greatly decreases due to various factors, And even if the illuminance is to be reduced, it is required to be reduced at a more gradual rate, but it is reduced at a set speed faster than necessary.

That is, the multisensor dimmer 300 of the present invention is not configured to be exposed to the frame 240 of the illumination lamp 200 viewed from the outside of the illumination lamp 200, but may be configured to be exposed to the back plate 210 of the flat illumination lamp 200 The illumination light 200 and the ceiling 22 are covered with the space 211 so that the ambient illumination or motion can be detected without any adverse effect on the aesthetic design of the appearance of the illumination light 200, The illuminance sensor senses the light incident through the light guide plate 220 and the diffusion plate 230 of the flat lamp 200 so that uniform information of the ambient illuminance can be detected even without a separate filter In the case of the microwave sensor, since it is closely attached to the light guide plate 220 inside the exposure space portion 211, even if there is no shield for blocking the noise, the back plate 210 made of metal, The light is transmitted through the light guide plate 220 and the diffusion plate 230, which can not block the microwave at all, so that the movement of the surroundings can be sensed.

In addition, the flat lamp 200 may be dimmed independently without a separate central control system for dimming control, and a plurality of flat lamps 200 may be grouped and dimmed in groups.

The remote controller 400 may include an IR transmission unit, a Zigbee communication unit, and a button input unit to control the multisensor dimmer 300 of the flat lamp 200, The level of the illuminance sensor and the room sensor of the multisensor dimmer 300 can be set and the lighting control mode of the flat lamp 200 can be changed and the initial ZigBee channel and group can be set using the DIP switch, (0 to 255), a high dimming level, a low dimming level, a holding time, an UP / DOWN dimming rate, a reception level Signal strength, emergency hold time, and the like.

The channel / group and configuration information setting method by the remote controller 400 is such that when the IR transmitter is directed to the multi-sensor dimmer 300 and the configuration information search button is clicked on the start screen of the remote controller 400, To the multi-sensor dimmer 300,

Upon receiving the search message, the multisensor dimmer 300 transmits the current configuration information to the ZigBee channel of the remote controller 400, returns to the ZigBee channel thereof,

When the remote controller 400 receives the response message, the remote controller 400 outputs the received configuration information to the screen, and if the response message is not received, outputs the abnormal message. When the configuration information is changed and the IR transmitter is directed to the multisensor dimmer 300 and the setting button is clicked, the configuration information is transmitted to the multisensor dimmer 300 through the IR communication. The setting button can be configured as a single / group / entire setting button.

Here, only the corresponding multisensor dimmer 300 is set, and the group sets the configuration information of all the multisensor dimmers 300 in the same group as the corresponding multisensor dimmer 300 at a time. The overall configuration of the multisensor dimmer 300 includes configuration information excluding the channel / group.

The multisensor dimmer 300 that receives the configuration information setting message through the IR communication divides the single / group / global setting and delivers the configuration information setting message to the ZigBee communication in the case of the group or the entire setting. When the channel / If so, reset the ZigBee channel / group. The changed configuration information is stored in the flash memory.

When the setup button is clicked on the start screen of the remote controller 400, the configuration information stored in the remote controller 400 is displayed on the screen, and the configuration information is changed and input to the FRAM memory of the remote controller 400 .

When the IR transmitter is directed to the multisensor dimmer 300 and the setting button is clicked on the start screen of the remote controller 400 or the screen on which the configuration information is output, the configuration information is transmitted to the multisensor dimmer 300 through IR communication.

If the channel / group is set to 0, the multisensor dimmer 300 operates in the stand-alone mode. If the channel / group is set to 255, the group is automatically operated using the ZigBee radio signal strength (RSSI) And the multisensor dimmer 300 receiving the setting related message through IR and ZigBee communication can blink the illumination of the flat panel illumination light 200 to indicate the reception status.

Also, when the IR transmitter is directed to the multi-sensor dimmer 300 on the start screen of the remote controller 400 and the search sensor level search button is clicked, the search message is transmitted to the multi-sensor dimmer 300 through the IR communication Upon receipt of the search message, the multisensor dimmer 300 transmits the current occupancy sensor level to the ZigBee channel of the remote controller 400 and returns to the ZigBee channel of its own.

Thereafter, when the remote controller 400 receives the response message, it outputs the received room sensor level to the screen. If the remote controller 400 does not receive the response message, the remote controller 400 outputs the abnormal message. When the number buttons 1 to 10 of the level to set the IR transmitter to the multisensor dimmer 300 on the remote sensor 400 output screen of the remote controller 400 are clicked, the remote sensor setting message is transmitted to the multisensor dimmer by IR communication do.

Accordingly, the multisensor dimmer 300 that has received the redundancy sensor level setting message through the IR communication modifies the level, transmits the response message to the ZigBee channel of the remote controller 400, and returns to the ZigBee channel of the remote controller 400 again.

When the IR transmitter is directed to the multisensor dimmer 300 and the group / total level setting button is clicked on the remote sensor 400 output screen of the remote controller 400, the group or the whole of the multisensor dimmer 300 is changed at once .

In addition, the illuminance sensor setting method is such that a search message is transmitted to the multisensor dimmer 300 through the IR communication when the IR transmitter is directed to the multisensor dimmer 300 and the illuminance sensor level search button is clicked on the start screen of the remote controller 400 Upon receiving the search message, the multisensor dimmer 300 transmits the current illuminance sensor level to the ZigBee channel of the remote controller 400 and returns to the ZigBee channel.

Upon receiving the response message, the remote controller 400 outputs the received illumination sensor information to the screen. When the remote controller 400 fails to receive the response message, the remote controller 400 outputs the abnormal message. In the illumination sensor level output screen of the remote controller 400, When the number buttons 1 to 10 of the level to be set toward the multi-sensor dimmer 300 are clicked, the illuminance sensor level setting message is transmitted to the multi-sensor dimmer 300 through the IR communication.

The multisensor dimmer 300 receiving the illumination sensor level setting message through the IR communication modifies the level, transmits the response message to the ZigBee channel of the remote controller 400, and returns to the ZigBee channel of the remote controller 400 again. The multisensor dimmer 300 set to the illuminance sensor level of 1 to 10 operates in the normal illumination mode.

When the IR transmitter is directed to the multisensor dimmer 300 and the illuminance setting button is clicked on the illuminance sensor level output screen of the remote controller 400, the illuminance setting message is transmitted to the multisensor dimmer 300 through IR communication, The dimming sensor 300 receives the illuminance setting message and transmits a high dimming level control message to the multisensor dimmer 300 of the corresponding group. After 1 second, the dimmer 300 measures the current illuminance and outputs a response message to the remote controller 400, To the ZigBee channel and back to its ZigBee channel again.

The multisensor dimmer 300 receiving the illuminance setting message operates as a master in the illuminance interlock mode, and the multisensor dimmers 300 receiving the high dimming level control message from the master in the illuminance interlock mode operate as a slave in the illuminated interlock mode .

In order to cancel the illumination interlocking mode, the master of the illumination interlocking mode is set to the illumination sensor level by the remote controller 400. When the master receives the illumination sensor level setting message, the master is changed to the normal illumination mode, The slave receiving the message may change the illumination sensor level to the remote controller 400 or the normal illumination mode when receiving the general illumination mode setting message from the master.

Also, in the general illumination mode dimming control method, when the multi-sensor dimmer 300 having an illumination sensor measures the current illumination value at the time of detecting a room, and compares the current illumination value with the illumination value of the set illumination sensor level, Adjusts the illumination of the illumination unit 200 to a high dimming level, transmits a room detection message to the multisensor dimmer 300 of the same group, and updates the holding time timer.

The multisensor dimmer 300 receiving the room detection message delivers the message to the other multisensor dimmer 300 and adjusts the illumination of the flat lamp 200 to a high dimming level and updates the holding time timer.

In this manner, each of the multisensor dimmers 300 adjusts the illumination of the flat-plate illumination lamp 200 to a low dimming level if there is no room detection during the holding time.

And the illuminance sensor level 10 may be configured to always adjust the illumination of the self-leveling lamp 200 to a high dimming level when the room is detected regardless of the brightness.

In addition, in the illuminated mode dimming control method, the multisensor dimmer 300, which is set to the illuminated interlock mode Master, transmits the occupant detection message to the other multisensor dimmer 300 upon detection of the occupant detection mode, And adjusts the illumination of the flat lighting lamp 200 itself to the final illumination interlock dimming level, updates the holding time timer, and then starts the illumination interlocking mode.

The multi-sensor dimmer 300, which is the master, periodically checks the illuminance value during the retention time when the room sensor is sensed. If the current illuminance value is higher than the reference illuminance, the dimming level is adjusted downward. Once the dimming level is determined, the dimming level of the illumination is adjusted and the dimming control message is transmitted to the multisensor dimmer 300 of the same group with the current dimming level value.

Upon receiving the dimming control message, the multisensor dimmer 300 transmits the message to another multisensor dimmer 300 and adjusts the illumination of the flat lamp 200 to a corresponding level.

The multisensor dimmer 300, which is a slave, transmits a room detection message to another multisensor dimmer 300 when receiving a room detection or receives a room detection message from another multisensor dimmer 300, ) Is adjusted to the final illuminated dimming level and then the retention time timer is updated.

In addition, the multi-sensor dimmer 300, which is a slave, delivers the room sensor message to the other multi-sensor dimmer 300, adjusts the illumination of the flat lamp 200 to the final illumination dimming level, do.

Thus, each of the multi-sensor dimmers 300 adjusts the illumination to a low dimming level if there is no room detection during the holding time. The multi-sensor dimmer 300 set to Master stops the illumination interlocking mode.

Also, the adjusting step of the upper / lower dimming level and the checking period of the illuminance value are obtained by dividing the difference between the current illuminance value and the reference illuminance by percent, and if the difference is large, the dimming level is increased and the check period is adjusted quickly. If the difference is small, decrease the level of the dimming level and adjust the check cycle slowly.

When adjusting the dimming level according to the illuminance change, the current dimming level is adjusted to the low dimming level when the adjusted current dimming level is below the low dimming level, and to the high dimming level when the dimming level is higher than the high dimming level, and the illuminance check period is set to 10 seconds.

Here, the illuminance check period and the up / down dimming level steps are as follows.

Illuminance difference More than 50% More than 40% More than 30% 20% or more over 10 3% or more Less than 3% Roughness check cycle 3 4 5 6 7 8 10 Upward dimming phase 30 24 20 16 10 4 One Down-dimming phase 15 12 10 8 5 2 One

[Roughness check period: seconds

Up / down dimming step: corresponding value in all 255 steps]

As described above, the steps may be divided into different steps to adjust the illuminance check period and the dimming step appropriately so as to perform the step dimming as a whole. The down dimming step is set to be smaller than the up dimming step to adjust the down dimming to be performed more slowly than the up dimming .
