I often do programming training for some engineers, and I am often asked questions about how to design the intelligent conference system, as well as the selection of equipment for the conference system. According to the past data, I listed the following points together with everyone. share it.
The analysis is mainly to analyze the customer's needs, what functions, and costs, and how to guide customers. The main points are as follows:
Propose function
Scene arrangement design highlights upgrade and expansion convenience maintenance cost
Obviously, the purpose of the analysis is for design, and the basis of design is functionality. According to the needs of users, we can identify the functional requirements and build the whole system according to the functions.
Therefore, the design plan should grasp the following aspects:
1. Customer demand for the system 2. The composition of the entire system 3. The function and composition of each subsystem 4. Equipment selection 5. Equipment list 6. System connection Figure 7. System implementation
From this, we can see that the system built according to the function requires the function division of the whole system, only each single function is realized, and finally the function of the whole system can be achieved. We call it system breakdown: system - subsystem - device - function.
Therefore, we can start from the function of the system, what kind of function a specific system needs to achieve, generally: conference room conference function; remote video conference function; audio; display function; camera function; signal management function; camera tracking function; Centralized control function; these parts are composed
　　 First, the conference room meeting function: discussion, voting, simultaneous interpretation, we can easily select the equipment required, can list the following equipment list: digital conference host; digital conference chairman unit; Digital conference representative unit; infrared transmitting host; infrared transmitting panel; infrared receiving unit; translation unit; wired simultaneous transmitting unit; wireless voting host; wireless voting terminal 2. remote video conferencing function inevitable, in order to realize remote video conferencing function, remote The video conferencing terminal is set up to implement this function, and we can select the matching device according to the needs.
Third, audio: 1. Mixer, equalizer, feedback suppression, etc. 2. Amplifier 3. Speaker 4.DVD, LCD
Fourth, the display function:
What kind of equipment can be used as a display device, which can be easily encountered in our daily life, such as: projection; LED; DLP; monitor; electronic table card, etc., thus, we can choose in the equipment list: Projector; electric projection screen; LCD TV; electronic table card host; desktop display unit and other equipment. 5. Camera function: In this part, we will indisputably think of cameras or cameras, or other video capture devices. In the equipment list, we can choose some manufacturers' cameras, for example: CREATOR shortcut camera VI, signal management: AV matrix; VGA matrix; DVI matrix; distributor; RGB matrix 7. Centralized control function: achieve centralized control effect , centralized control of lighting, sound, signal switching, etc. in the conference room, and wireless operation!
Equipment list: central control host (eg: pgm2); wireless touch screen; power controller dimmer; volume controller; infrared launcher
Above, we have determined the equipment through functional requirements. This leads to the framework of each subsystem, and then through the central control system, the various subsystems are organically and orderly connected together to form a complete intelligent conference system.
Then, if the system plan is established, we should finalize and implement the product. Product stereotypes 1. Well-known brands;
If the equipment brand you choose is very famous, it is very recognized in these industries, which will bring convenience to the promotion of the market.
2. High cost performance;
Price is a sensitive issue, but as long as the products we offer are value for money, you can stand there when you get there. Users are very willing and willing to buy such products.
3. The comprehensive strength of the manufacturer;
The manufacturer has a strong comprehensive strength and can provide a very strong backing for everyone.
4. Support and services provided by the manufacturer;
Support: can be price support, technical support, personnel support, etc.; service: after sales.
Implementation When we have equipment, we have a solution, we also know where the equipment is installed. The next step is to consider entering the market. In general, the following aspects are achieved:
1. Wiring requirements:
Strong and weak wires are separated;
The power supply is separated from the signal line;
The power supply is separated from the control line;
All wires must be laid through the pipe;
The entire system uses a unified power distribution box to avoid power interference between devices;
In harsh environments such as high voltage and strong magnetic fields, shielded wires should be used; in humid environments, sheathed wires should be used.
