Intelligent lighting control system scheme 3.
1 The system scheme takes the comprehensive building as an example, adopts the ALIBUS intelligent lighting control system of Acquari, and adopts intelligent lighting control
for the lobby, conference room, stairwell, public corridor, elevator hall and other places.

The topology diagram of the intelligent lighting control system of the building is shown in the following figure
.

The lobby is the only way for personnel to enter the building, good decoration effect and design layout can give people a comfortable space, but there is no good lighting to set off the difficult to achieve the effect
that the designer wants.

In order to enable personnel to enter the lobby at any time, they can feel the comfortable environment
brought by the lighting effect.

Office hall area lighting with infrared sensors for human body induction, the use of branch circuit switch control, preset scene control, through the smart panel or sensor one-key switch scene, both to meet the aesthetics, but also take into account the energy saving
.

Conference room is an important functional place in the office building, the use of manual control of the sub-circuit, scene control, as needed into meeting, office, rest and other scene modes, pre-elaborate design of a variety of lighting scenes, when using only need to select the corresponding scene intelligent panel buttons, the lights will automatically open
in accordance with the set way.

Set up electronic tag panels at the door of the conference room for room managers to manually select or control in real time according to their needs to meet different needs
such as meetings, projections, speeches and plots.

Stairwells, public corridors, and elevator halls are open public spaces
.

The use of sub-loop switch control, dynamic and static detection control, local control, etc
.

To maintain the basic brightness of the lights in public areas, you can also switch and control the lights of a certain circuit through the system, and infrared motion detectors are installed in the corridors and public corridors, and the automatic control mode
of people to automatically turn on the lights and turn off the lights when people go delayed.

In order to facilitate the on-site staff to control and manage the lighting in the area, an intelligent control panel
is also installed at the door of each corridor in the site.

Normal working hours are fully on, non-working hours are changed to dimmed lighting, and only a small number of lights can be lit when no one is on holidays to retain enough illumination for video surveillance
.

Managers can also monitor and control the lighting of corridors and public corridors through the central control
computer.

ALIBUS intelligent lighting monitoring software is installed in the internal control room of the building, real-time monitoring of the status of each drive circuit in the building, can be opened remotely according to the actual situation of the site/Close specific circuits to reasonably avoid situations where people forget to turn off the
lights.

2 In the sensor input device, the sensor is also a device
in the intelligent lighting system.

Sensor technology takes the acquisition and transformation of information as the core, is the source of expanding information resources, and has the key function
of connecting computer, communication and automatic control technology.

Sensors are mainly divided into the following types: (1) manual lighting switches or dimming to monitor energy consumption without affecting the visual effect
.

(2) Infrared sensor
.

As long as the temperature of an object in nature is higher than -273 ° C, it always continuously emits infrared radiation
outward.

The higher the temperature of the object, the smaller the peak wavelength of the infrared radiation emitted by it, and the greater the energy emitted by the infrared radiation
.

When a person enters the sensing range, the infrared sensor probes (1) the illuminance sensor
.

The illuminance sensor can be used for lighting, according to the natural light level of the space control of the sensor as an input module, can detect the movement of people or objects in the room and the current real-time illumination, and in accordance with the preset logic to send control commands to the lighting distribution box (cabinet) in the driver to achieve automatic control and adjustment
of lighting.

Measured human infrared spectrum, automatically turn on the load, as long as the person does not leave the sensing range, it will continue to turn on, once the person leaves, the delay automatically turns off the load
.

(3) Microwave radar detector
.

The principle of microwave radar sensor is that the transmitter generates a low-power microwave signal, and radiates into the air through the transmitting antenna, receives the reflected echo of the object received by the antenna, amplifies and mixes RF processing in the receiver, and outputs the intermediate frequency signal, and then analyzes the measurement results
through radar signal processing.

Radar sensing has more advantages
over the control of sound and light control and infrared external sensing.

It has strong anti-RF interference ability, is not affected by temperature, humidity, etc.
, and can achieve both induction and appearance integrity
.
