Conference 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;
