The difference between intelligent lighting control system and building automation ... I do lighting, and I know nothing about their control methods and principles.

Intelligent lighting control system refers to indoor and outdoor dimming control system. The biggest feature of this system is scene control. There can be multiple lighting circuits in the same room, and a certain lighting atmosphere can be achieved by adjusting the brightness of each circuit. This is the so-called scene. You can set different scenes in advance, switch the fade-in and fade-out time of the scenes, and make the lights change softly. Clock control, using the clock controller, makes the lights appear according to the daily sunrise and sunset or the change of time law. Using various sensors and remote controllers to realize automatic control of lights.

Building automatic control system refers to the electrical equipment except lighting control system in the building, such as elevators, pumps, fans, air conditioners, etc. Its main working property is strong electric drive. Usually, these devices are in an open working state, that is, they do not form a closed loop. As long as the power supply is connected, the equipment is working. As for the working status, progress, energy consumption, etc., it is impossible to obtain data online in time, let alone use and save energy reasonably. At present, building automation is to monitor the above-mentioned electrical equipment online, and detect the working state of the equipment by setting corresponding sensors, travel switches and photoelectric controls. , and through the line back to the central computer in the control room, the computer will get the analysis results, and then back to the equipment terminal for mediation.

At present, the most commonly used control mode of the two systems is to connect and communicate through two buses of PowerBUS. Please refer to the structure diagram below.
