After determining the size of the meeting room, it is necessary to select different meeting room system function modules to be integrated according to the needs of enterprise users. Numerous functions are provided by different system modules, and enterprise users can choose different system modules to combine and match according to their actual needs. Generally speaking, the system modules that a standard multi-functional conference room should have mainly include the following: 1. Central control system 2. Display screening system 3. Sound reinforcement system 4. Conference pickup system 5. Shading lighting system Among the five basic system modules, the central control system is at the core, while the other parts are functional modules that directly provide services. In addition, according to actual needs, the multifunctional conference room will also add modules such as simultaneous translation system, video conference system, data output system, and data exchange system. lift central control system The central control system is composed of a central control host, operation terminal, signal receiving module, switch panel, control software, power supply module, etc. It is the core of the multifunctional conference room. After effective connection, it can control the opening, running and closing of various functional system modules. . The central control system is mainly connected to the controllers of the peripheral function modules through the network, IR wireless, data lines, etc. The user directly operates on the control software interface of the operating terminal to control the switch operations and mechanical actions of various devices. The advantages of the multifunctional conference room can be vividly expressed on the interface of the operation terminal of the central control system. Whether it is the turning on and off and related operations of projectors, players, computers and other equipment, or the related switching of audio, video, and network, even the turning on and off of electric curtains and lighting can be directly operated by touch. The convenience and high efficiency brought by this integration are very useful for multi-functional conference rooms of various sizes and applications. Imagine that when you need to use a projector to demonstrate a video, in the past, someone had to draw the curtains and turn off the lighting; in a multifunctional conference room, the central control system can automatically reduce the brightness of the lights and turn off the lighting around the curtain. Light up and close the curtains. Which is more convenient is clear at a glance. Display screening system At present, the display and projection system generally adopts the mode with the projector as the core, and some special occasions also use flat-panel displays, projectors, elevators and other equipment. In order to perform display and projection control, all display and projection equipment will be connected to the VGA matrix and the AV matrix, and the VGA matrix and the AV matrix are connected to and controlled by the central control host through special data lines and equipment. The video signals output by computers, players, cameras and other equipment will be uniformly output to the VGA matrix and AV matrix, and then play and other operations according to the signal of the central control system. The biggest function of the display projection system lies in the management of video signals and the switching of display devices. In many small and medium-sized meeting rooms, there is only one projector as a display device, so there is no problem of switching. Of course, there are also some special industries that require multiple display devices. For example, some financial and securities companies need to monitor price trends for a long time and must additionally be equipped with flat-panel displays as auxiliary display devices. At this time, there is a problem of device switching. Financial and securities corporate conference rooms have higher requirements for display and projection systems Compared with the switching of display devices, the management of video signals is more important in meeting room applications of many enterprises. This should be easy to understand. Nowadays, it is normal for companies to have a laptop computer when they hold a meeting. Whose video screen should be displayed on the projector at this time? This needs to be controlled by the VGA matrix, the bridge in the display and projection system. Sound reinforcement system "Audiovisual audiovisual", the sound amplification system also plays an important role in the multi-functional meeting room, especially in the large and medium-sized meeting rooms with a large number of participants. A good sound amplification system should meet the following requirements: the sound is loud and clear, covers the entire space, and has no flaws in fidelity. In layman's terms, it is necessary to ensure that the people participating in the meeting can clearly hear the voices of speeches and presentations in all positions, and at the same time avoid problems such as echo and howling. In order to meet the requirements, it is necessary to consider the decoration of the conference room (the use of attracting materials to make diffuse reflection walls), the processing of mixing noise reduction and howling, sound amplification, and the layout of speakers. Conference pickup system The conference pickup system mainly appears in large and medium-sized conference rooms or conference rooms where there are teleconferences and video conferences, allowing the entire conference to proceed in an orderly manner. If in large and medium-sized meetings attended by dozens of hundreds of people, everyone is talking in a mess, then I am afraid that we will not gain anything other than the buzzing noise. At this time, the conference function module in the conference pickup system is needed. The entire functional module is composed of a digital conference host (management of each microphone speech mode and other operations), a wireless microphone, a central controller, etc. The relevant sound processing will also use the tuning module. In order to control the conference, the management and control mechanism of the digital conference host is more important. The speech control of the chairman unit and microphone unit should be specific to the speech mode, output volume and earphone monitoring volume. Remote Internet teleconferencing is another important aspect that requires a conference pickup system. If an enterprise has branches in multiple regions, it is unrealistic to convene people to have a meeting in one place, both in terms of time and cost. This is the reason for the emergence of remote Internet teleconferences. When holding a network conference, if you want to collect the voices of the participants more clearly, and reasonably control the order of speaking, this requires the conference sound pickup system to control. Shading lighting system When using the projector, you need to draw the curtains and reduce the brightness of the light. This is the fundamental demand for the blackout lighting system. The shading lighting system is the basic condition for the normal use of the multifunctional conference room, which can be divided into two sub-systems: shading and lighting. The shading system mainly controls the curtains, and sends instructions to the curtain controller through the central control system to control the opening and closing of the electric curtains, thereby adjusting the indoor brightness to meet the needs of the display projection system. The function of the lighting system is basically similar, but it is mainly through the central control system to command the lighting controller to control the brightness of the light.
