An intelligent centralized control system is used to centrally control all equipment in one or more meeting venues, including the switching of power supplies for various subsystems and equipment, adjustment of ambient lighting, raising and lowering of screens, opening and closing of curtains, operation of various multimedia devices, and so on. Users can control all system equipment simply by using a color touchscreen.

This system can centrally control the following devices:

1) Playback, stop, pause, fast forward, rewind, and recording of DVD and VHS recorders. Control method: IR infrared control.

2) Pan/tilt control, zoom, and focus of cameras.

Control method: RS-485 serial port control.

3) Audio and video signal switching of matrix switchers.

Control method: RS-232 serial port control.

4) Power switch, video/computer input selection, and advanced adjustments of projectors.

Control method: RS-232 serial port control or IR infrared control.

5) Power switches for various devices.

Control method: Relay control.

6) Audio system volume control.

Control method: Bus-connected volume level controller.

7) Lighting system control.

Control method: Dedicated lighting control silicon box.

8) Control of various motor devices (screens, curtains, electric doors, etc.).

Control method: Relay control.

This control system is highly stable, reliable, and durable, suitable for 24-hour uninterrupted operation.

The entire system only requires maintaining a clean working environment free of excessive dust and operating temperatures that are too high (>40 degrees Celsius) or too low (<0 degrees Celsius).

The main controller has no consumable parts and requires no maintenance under normal use.
