As society continues to evolve, the frequency and importance of information exchange and communication have markedly increased.
Various audio-visual and projection equipment, along with conference systems, have begun to permeate all sectors—including conference rooms and audio-visual teaching spaces.
Large conference rooms are often equipped with advanced features like simultaneous interpretation systems, electronic voting systems, large-screen projections, and multi-screen switching systems.
However, the use of multiple devices can lead to complex operations.
Operators often need to manage various tasks, such as turning on the power for multiple devices, turning off lights, switching between different audio and video signals, and frequently alternating projection screens.
In response to these challenges, central control systems have been developed. These systems enable centralized management of these devices.
Allowing seamless control over resource switching in both conference rooms and classrooms.

What is central control system?
Central control system refers to equipment that centrally manages and controls various equipment such as sound, light, electricity, etc.
It is widely used in multimedia classrooms, multi-functional conference halls, command and control centres, smart homes, etc.
Users can use button control panels, computer monitors, touch screens and wireless remote controls to send serial port instructions through computers and central control system software.
Control projectors, display stands, DVD players, video recorders, decks, power amplifiers, microphones, computers, notebooks, video wall screens, electric curtains, lights and other equipment
When several independent central control systems are connected, a networked central control system can be formed, which can realize resource sharing, audio and video mutual transmission and mutual monitoring.
Collaboratively control modern audio-visual equipment such as computers, DVD players, video recorders, and video booths.
And centrally control electric curtains, lights, curtains and other equipment to create modern multimedia with high-definition, high-fidelity, and controlled sound and light background through large-screen projection. Audio-visual teaching environment.
It is suitable for schools to carry out multimedia teaching, courseware teaching, special speeches, reports, demonstrations, etc.
The composition of the central control system
As a system, the central control system generally consists of four parts:
User interface;
Central control host;
Various control interfaces;
Controlled equipment.
Characteristics of central control
Digitization:
All signals transmitted within the system are digital signals, and the microphones used by the delegates adopt "analog-to-digital" conversion technology.
Most unit equipment also uses analogue-to-digital and digital-to-analogue converters.
So external analogue equipment (such as broadcasting, recording, wired or wireless audio equipment, etc.) can directly enter the digital system network through the audio media interface.
Modularization:
For meetings with any level of requirements, the corresponding system can be formed through a modular selection of equipment that meets the requirements.
For the established system, more multimedia devices can also be added and controlled through computer software to further expand the system.
Intelligentization:
There is a connection between systems, a language that can communicate, and communication with each other.
The originally relatively independent self-systems are organically combined and interacted.
High efficiency:
completely overturning the original conference guarantee model, saving personnel and steps.
Simplification:
It saves cumbersome operation steps for conference guarantees or conference controllers and reduces possible errors caused by cumbersome steps.
Improve the image:
The stylish and beautiful wireless touch screen and the touch screen customized for you can perfectly enhance the taste of your conference room.
When choosing a central control system, you should pay attention to the following aspects:
First, the system must be stable and reliable.
The purpose of installing a central control system is to simplify operations so that staff can easily control various equipment to achieve twice the result with half the effort.
If the system is unstable, not only will the operation not be simplified, but the use effect will be affected.
Therefore, quality should be put first rather than price when choosing.
Secondly, we should pay attention to the openness and compatibility of the system.
It is easy to install and upgrade, and it is not troublesome to add or replace equipment;
The control interface is simple and clear, with clear logic, and the operation is convenient and fast.
Finally, it should be noted that there are multiple ways to control the operation.
Most control systems today have touch screens, software, manual control panels and handheld remote controls.
The computer operation level of different users is inconsistent. Some users are not familiar with computer operations and can use handheld control panels, touch screens, remote controls, etc.
Video wall display system control
All functions of the video wall can be controlled by controlling the host's RS232 serial port, such as turning on/off and input switching of video images and computer images
And can automatically implement associated actions, such as automatically closing the video wall when the system is turned off.
You can use the video preview function of the control terminal to confirm that the video image played is the required video image before projecting the video to the screen through the video wall.
iSEMC has LCD video wall, LED video wall, used in NOC, EOC, utility and crisis response units across the globe. Meeting a wide set of diverse requirements, our solutions offer both IP and KVM solutions meaning sources can be routed to any screen in any location and controlled from anywhere.
Control of A/V system
By controlling the host's RS232 serial port, control the switching of the video matrix and select the required image to output to the projector.
By controlling the host's infrared control port and infrared transmitter wand, you can control all actions of the device, such as play, pause, stop and other functions.
Use the volume controller to control the output volume of the power amplifier.
Final Thought
The development and application of central control systems have broad prospects.
From simplifying conference room operations to creating smart home environments, central control systems are becoming an important part of modern technological life.
In the future, with the integration of artificial intelligence and Internet of Things technology, central control systems will be more intelligent and personalized, bringing users a more convenient and efficient operating experience.
