The use of multiple devices inevitably leads to cumbersome equipment operations. For example, to turn on multiple devices, turn off the lights, frequently switch between various audio and video signals, and constantly switch between projected images wait. In this situation, a "central control" device that can centrally manage these devices and simultaneously control various resources in conference rooms and classrooms emerged. Zhejiang University Central Control Power Supply The manufacturer explains relevant matters for you.
The central control system uses multi machine communication technology and system integration technology to combine the controlled equipment according to the actual operating requirements of the user, and then integrate its final operation process for each equipment into a simple operation. In short, central control can centrally control equipment such as video recorders, AV matrices, VGA matrices, DVD players, video booths, projectors, electric screens, electric curtains, and lighting.
Basic composition of central control
Host: It functions to receive control signals from the touch screen, interpret, and execute them.
Color LCD touch: Direct preview view, easy and fast full range control.
Wall-mounted panel: Usually installed at the door for easy access and operation.
Volume control module: used to control audio equipment.
Incandescent lamp dimmer: Used to control and adjust lighting equipment.
Strong current relay module: used to control electric hangers, screens, equipment power supplies, fluorescent lamps, and other equipment.
Infrared emission rod: used to control infrared equipment such as DVD/video recorder/physical exhibition stand.
External power supply: used to supply power to all devices.
Central control generally consists of four parts:
1. User interface;
2. Central control host;
3. Various control interfaces;
4. Controlled equipment.
Specifically, it can be divided into the following modules: audio and video switching module, VGA computer signal switching module, infrared learning and transmission module, device power management module, electric screen control module, voice/volume processing module, control interface processing module, and power module.
In addition to completing the specific functions of the above modules, the central control can also add other control or communication functions through programming. If you have any doubts or needs about this, you can come to our website at any time http://www.sdjkyqyb.com consulting service
