Description

Multi-channel illumination illuminance control system and its method {Illuminance control system and method for multi channel lighting}

The present invention relates to a multi-channel illumination illuminance control system and a method thereof, and more particularly, a user arbitrarily sets an illumination load value according to an external illumination value or automatically specifies illumination illumination according to a load value set in the system. The present invention relates to a multi-channel illumination illuminance control system and method for not only smoothly controlling the intensity of illumination intensity but also monitoring the operating state of the lighting and the amount of power used.

Recently, various efforts for energy saving have been made worldwide, and there is an urgent need for reduction of energy used in buildings, which are known to occupy about 40% of total power energy.

Buildings are largely divided into residential buildings and office buildings, which are reported to be used by lighting equipment for about 25% of the total power consumption. The most widely used to reduce the lighting energy of office buildings is to actively introduce external natural light, which requires dimming control of lighting equipment.

In order to control the dimming, the dimming command is provided to the lighting equipment as an analog output, and the lighting equipment performs the dimming command to adjust the brightness. However, the analog signal is vulnerable to noise, and when one analog output signal is connected to multiple lighting equipment or the length of the wire is long, there is a problem that the voltage decreases due to an increase in contact resistance.

When the noise is generated and affects the dimming signal, the brightness, which is the dimming level of the lighting equipment, may be unstable and fluctuated by the influence of the noise. When the voltage drops, the dimming level is lowered, making it difficult to control the dimming to the desired level.

In order to solve this problem, DALI, a standard communication method for dimming control that replaces wired communication method of lighting equipment, is spreading around the world, mainly in Europe. However, because DALI also uses wired communication, changing the ping information of a communication group to another subnetwork for the lighting equipment can be a hassle of changing the communication line wiring.

Although the lighting control device 100 is composed of four channels, the number of channels may vary depending on the circuit configuration, and the capacity per channel may be changed.

The lighting control device 100 includes an illumination sensor 110, a wireless communication unit 120, a power stabilizer 130, a device changeover switch 140, a frequency conversion circuit 150, a power control circuit 160, and a central processing unit.

The illuminance sensor 110 measures an external illuminance value, and the measured external illuminance value is used as basic data for setting an illuminance value of illumination.

The wireless communication unit 120 applies RS-485 communication to perform communication between the system control and the lighting control room 400. The power stabilizer 130 controls the lighting power of the lighting group 200 when overloaded, and may be composed of two fuses.

The device changeover switch 140 is connected to the switchboard 1 301, the switchboard 2 302, the switchboard 3 303, and the switchboard 4 304, respectively, and selects and connects each control board 100a. The device changeover switch 140 is connected to a control board 100a for directly controlling the illuminance of the assigned lighting group 200, respectively.

The control board 100a includes a part or the whole of the lighting control device 100, and as shown in FIG. 1, the power stabilizer 130, the device changeover switch 140, the frequency conversion circuit 150, The power control circuit 160, the central processing unit 170, the cooling unit 180, the current sensing circuit 182, the channel current sensing circuit 181, and the power insulation unit 190 may be included. The control board 100a may be manufactured in a card type, and four cards may be extended to the main body of the lighting control device 100.

The frequency conversion circuit 150 minimizes surge and noise in fluorescent and LED lighting using a ballast by controlling the illumination in the high frequency region of the 20 kHz band.

The channel current sensing circuit 181 may be installed between the power stabilizer 130 and the frequency conversion circuit 150 and include a rectifier circuit 181a.

The power control circuit 160 may include a current sensor (hall sensor) for checking the amount of power used for each channel. The central processing unit 170 may simultaneously control the three-phase alternating current branched from the switchboard 300, and may control the illumination illuminance of the lighting group 200.

The power supply unit supplies power required for the system, and the three-phase alternating current is branched from the main control unit (MCU) control power supply 510 and the switchboard 300 to supply the power required for the central processing unit 170. The lighting load power 520 transmitted to the lighting group 200 through the lighting control power 530 is supplied so that the power of each phase is separated.

The lighting control device 100 requires a system expandability having a card type in order to control the illumination intensity of the lighting group 200 in a large office or a large building, but a collision between three-phase ACs does not occur in the system expansion. Safety should be ensured to prevent

 One central processing unit 170 must control three phases at the same time to control the large-capacity lighting group 200.

First, three-phase alternating current is branched in the switchboard 300 so that the lighting of the lighting group 200 is turned on through the breaker CB. At this time, the light load power supply 1 is R phase and N = AC220V, the light load power supply 2 is S phase and N = AC220V, and the light load power supply 3 is T phase and N = AC220V.

In addition, when the three-phase alternating current branched from the switchboard 300 is used for lighting control through the lighting control device 100, the MCU control power supply 510, the lighting load power supply 520, and the lighting control power supply 530 are used. When necessary, the MCU control power supply 510, the lighting load power supply 520 and the lighting control power supply 530 are insulated, and the GND of the lighting load power supply 520 and the lighting control power supply 530 is common.

If the GND of the light load power supply 1 and the light control power supply are common, and the light load power source 2 and the light load power source 3 are present, the light load power source 2 and the light load power source 3 become short.

Accordingly, the lighting control power supply 530 supplies V1, V2, V3, V4, V5, V6, V7, V8, V9, V10, V11, and V12, and the lighting load power supply 1 is common with the lighting control power supply V1 (COMMON The power supply 2 for the lighting load is common to the lighting control power supply V2 and the GND to separate the power between the phases.

In this way, one central processing unit 170 can control the three-phase alternating current to construct a card-type multi-channel illumination illumination control system, one-touch when removing the card from the system It can be separated so that A / S response can be quick.

In the multi-channel illumination illuminance control system of the present invention, when the controllable lighting is described using fluorescent lamps as an example, the number of fluorescent lamps for each breaker is 20 to 40, and the number of breakers is 6 (120-240) to 12 Dogs 240-480).

Next, in the case of forcibly adjusting the illuminance of the lighting according to a user's request or instruction, the CPU 170 arbitrarily controls the load of the lighting in units of 0.1% to 0% to 100%.

Finally, when the illumination illuminance control is performed according to the sum of the external illuminance value acquired by the illuminance sensor 110 and the illuminance value for each time zone stored in the program set by the user, the present invention is applied to the external illuminance value obtained by the illuminance sensor 110. Lighting illumination control is performed by adding illumination illumination, so that the user may minimize inconvenience caused by illumination illumination.

The lighting control device 100 may control the illuminance in the high frequency region of 20 ㎑ to minimize the ballast load of the fluorescent lamp or the LED light and the surge phenomenon of the illumination, and set the width of the illuminance to be changed by 0.1% to change the illuminance. Smooth illuminance control is performed so that the user does not feel the extent of the illuminance change. In other words, the fluorescent lamp or LED using the ballast in the frequency band of 20 kHz is the most stable without trembling, and the wide range of illuminance changes, resulting in a power saving range of 0 to 65%.

For example, if the current illuminance value is 50 and the target illuminance value is 55, the lighting control device 100 does not directly change the illuminance value from 50 to 55, but instead of 50, 50.1, 50.2, .... 54.8 , 54.9, 55.
