Large Bay Office

1กข DALI dimming method
Adopting T5 light source and DALI dimming ballast, due to the possibility of frequent adjustment of office seats in large compartments, the lighting control system's
The function should also meet this requirement, that is, after the seat changes, simply edit the system program again to control the lighting and rearrange it
The office desk corresponds to and can be independently controlled without the need for rewiring< br /> By combining a dynamic and static detector with network communication function and DALI dimming system, the light gradually dims when people are on and away for a certain period of time.
And turn off or save a minimum brightness. It can achieve maximum energy conservation< br /> Generally, the large bay area is divided into several small areas, with each small area corresponding to one or several 'intelligent programmable control panels' (nearby
Installed on walls or columns within the corresponding small area, different lighting scenes can be manually selected through the on-site control panel, thereby achieving
In terms of centralized control of lighting in the small area and vertical wiring, only the network cable from the ceiling to the intelligent control panel on the wall (column) needs to be considered.




The case is as follows:
The office of a foreign-funded group in Pudong, Shanghai uses T5 fluorescent tubes with DALI dimming ballasts< br /> The owner requires the use of daylight sensing detectors for energy-saving control in the large bay, and each lamp can be independently addressed and dimmed for control.
DALI dimming ballasts are also used in independent offices, and each office is equipped with a lighting control panel that allows for manual selection of lighting scenes< br />
Case analysis:
The 105 lighting fixtures in the large bay office can theoretically be controlled by 2 DALI controllers (model: MP-DALI64), which are
For ease of maintenance, we actually use four DALI controllers (model: MP-DALI64) to control, and we have set up three in this large bay
A light intensity sensing detector detects the intensity of sunlight and uses the dimming signal (0-10Vdc) output by the detector as the 'signal input module MP06DI'
The signal input enables the dimming signal to be transmitted on the lighting control network and transmitted to the MP-DALI64 controller for control output
The DALI signal changes the output of the DALI dimming ballast, ultimately controlling the brightness of the T5 lamp tube< br /> Independent offices with 1 lighting control panel per room, all independent offices share 1 DALI controller MP-DALI64,
Through programming, the control panel of each independent office can only control the brightness and scene selection of the lighting fixtures in that area, without affecting other rooms< br /> Two meeting rooms each use one DALI controller and one lighting control panel< br /> The DALI control connection and the arrangement of the light intensity detector are shown in the above figure.

Equipment used:
7 DALI controllers MP-DALI64< br /> 10 lighting control panels MP06SS< br /> Three MP-PE1 light detection dimmers< br /> 1 signal input module MP06DI;

2กข The practice of switch control
Case: The office of a certain group in the Jiali Center of Jing'an Temple in Shanghai uses MP switch control modules for centralized control of all lighting fixtures. Each floor
Divide into several small areas, each with one or more intelligent control panels to control the lighting scene within that area. Control the entire network time< br />
Meeting Room -
Simple meeting rooms only consider controlling lighting; Considering that the meeting time in the conference room is relatively long, and ordinary infrared motion detectors are not very
Sensitive, it is possible that during the meeting, the infrared motion detector did not detect the subtle movements of the attendees and turned off the lights, resulting in
Unnecessary troubles, therefore it is recommended to use relatively sensitive microwave motion and static sensors to detect the presence of conference room personnel. When someone enters,
The lights gradually turn on, and after the personnel leave for a period of time (the time value can be set), the lights gradually dim< br /> The wireless iPAD control for controlling lights, curtains, projection screen, projectors, air conditioners, etc. shall be considered for medium-sized meeting rooms< br /> The advanced conference room considers the conference central control system, in addition to the wireless iPAD control of lights, curtains, projection screen, projectors, air conditioners, etc.,
It can also control audio and video matrices, as well as remote conferencing through television, telephone, and video conferencing

The case is as follows:
The control requirements for the meeting room of a company in Hefei: control lights, electric curtains, Sanyo projectors, projection screen, and independent air conditioners< br />
Case analysis:
The lamps in the conference room are divided into two circuits D7 and D8, which are used for dimming control. The rail type optical module DI0405 is selected. The curtain is a single layer, and only two switch control circuits, S3 and S4, are needed to control the forward and reverse rotation of the motor of the electric curtain respectively. The control of the projection screen also requires only two switch control circuits, S1 and S2, to control the rise and fall of the motor of the projection screen respectively. As shown on the left of the above image< br /> The control panel is installed on the wall at the entrance of the conference room, with a standard 86 embedded bottom box. The control box is placed in a low cabinet. One network cable needs to be laid from the control box to the projector, and the projector should be of Sanyo brand. Sanyo manufacturers have provided control codes that allow users to remotely control the projector's' power on/off/blue screen/black screen/video/volume up/down/volume on/off/display ratio 16:9/display ratio 4:3 'through the RS485 network, allowing users to control the projector through protocol through the control panel. Lay one network cable from the control box to the 'Air Conditioning Infrared Control Module' in the ceiling above the independent air conditioner. The 'Air Conditioning Infrared Control Module' can learn the infrared code of the independent air conditioner's built-in infrared remote control, thus controlling the temperature and wind speed of the air conditioner, cooling and heating mode, etc; As shown on the right of the above image< br /> Equipment used:
Dimming control track type module, model: DI0405 1 piece< br /> Switch controlled track type module, model: DR0816 1 piece< br /> 1 12V/100W switching power supply< br /> Intelligent control panel, model: MP06SS 1 piece< br /> Air conditioning infrared control module, model: MP-INFRA 1 piece;
