Abstract: Intelligent lighting control system is more and more widely used at this stage. This article introduces the specific application of Acrel intelligent lighting control system in a computer room management center, briefly analyzes the design specifications of KNX technology, and outlines Acrel-Bus intelligent lighting The specific structure and control method of the control system. KNX technology is mainly used in the control field of large public construction projects such as houses and buildings. The most significant advantage of this system is that the structure of the system is clear and convenient during system debugging and maintenance. When a certain part of the system fails, other parts can continue Work to improve the safety and reliability of the system.

Keywords: computer room management center; intelligent lighting system; energy saving and emission reduction; lighting control;

1.System Composition  The system composition structure diagram is as follows. The bus power supply, driver, gateway, coupler, input module, etc. need to be installed in the distribution box. The sensor is generally installed in the public area, and the panel and touch screen are generally installed in the room on duty. Note that the wiring of each module cannot form a ring. For relatively small projects, the system can choose a 10-inch central control screen, which does not require an IP gateway conversion protocol, and is simple to set up and low in cost. For relatively large projects, it can be connected to a computer through an IP gateway to realize remote control of the terminal.

2.System function  The product has a variety of control methods to choose from, which can meet the needs of different customers. Such as local control, automatic induction control, timing control, remote centralized control, etc., the control method is more flexible. While realizing automation, it greatly reduces the management cost of the staff on duty, and improves the management level and work efficiency.

3.Advantages of the system1. The system can remotely and centrally control the on-site lighting, air conditioning and curtains through mobile phones, touch screens, and computers, making the control more convenient and intelligent, and the user experience more perfect.2. The control modules in the functions, while realizing automation, greatly reduce the management cost of the staff on duty, and improve the management level and work efficiency.7. When upgrading the control module in the system or changing the system function, there is no need to increase the connection line or shut down the entire system. It can be realized by only changing the equipment parameters. The maintenance is convenient and the operation is simple.8. The system can be linked with the fire fighting system. When a fire alarm occurs, the emergency circuit is forced to open to facilitate the evacuation of personnel, thereby reducing the risk of casualties and improving the safety of the building.

4.Description of smart lighting control module

  The above is the structural typology diagram of Acrel-bus smart lighting control system. The system architecture adopts layered structure, advantageous mainly in the following three aspects:(1)Enhancing system reliability. As each area and each line is distributed with KNX power, the electric isolation enables other parts to continue with operation when something goes wrong with one part of the system.(2)The data communication within one line or one area will not affect communication in other areas.(3)During system commissioning and maintenance, a clear system structure will provides high maintenance efficiency.

5.Installation Site

6.Ending  With the development of society and the widespread application of electric power, Acrel's intelligent lighting monitoring system has become the choice for large-scale and multi-users such as important engineering projects, landmark buildings, and large-scale public facilities throughout the country. The energy-saving method of intelligent lighting system in buildings realizes resource saving by strengthening management, saving costs, effectively ing natural light sources, and sharing lighting system resources. There are many advantages and practicability of intelligent lighting system. At the same time, intelligent lighting system is constantly developing and improving. In the future, buildings will use intelligent lighting system to control lighting in an all-round way.
