Construction scheme of video conference system
Construction, installation and debugging of video conference system:
First, set up the display device first.
The adjustment of display equipment is mainly the adjustment of TV set. The installation position should be horizontal and vertical. The input signal source of TV set should be adjusted to HDMI interface input. VGA matrix can also be used to VGA interface of TV set.
Two, next, we need to debug each camera.
The contents of the debugging include:
1. The range of motion and control of the platform, the focus of the lens, the adjustment of white balance, the adjustment of sensitivity, the output mode, the adjustment of prefabricated points and so on. The debugging of the editing and distribution equipment mainly includes adjusting the input and output mode of the signal and selecting the format of the characters.
2, Tenveo HD camera control, using external power and internal power respectively.
When the pool is connected with HDMI high-definition data line to the display terminal, real-time image and video recording, lens focus, white balance adjustment, etc.
3, indoor surveillance camera image to monitor terminal image situation. Requirements can basically see the real situation of the venue. When the debugging of each system has been completed separately, and confirm that each device is in good condition, there is no obvious debugging improper, it should start the whole system debugging. The main task of the overall debugging is to check whether the interconnected parts of the system are coordinated and whether they will interact and interfere with each other when they work together.
Three, system simulation operation
1, First of all, we should measure the current of each phase of the power supply line when the system is running separately and in general. Actual operation and theoretical value will certainly be different, the actual operation of the current situation must be measured, if the actual measured value and theoretical value is found to have a large gap, or the proportion of each phase of the current distribution gap is large, line current abnormal phenomenon, must be re-rectified to ensure the safety of electricity.
2. Next, we should check the stability of each device during full load operation and long time operation. These checks include changes in sound quality, the stability of the wireless microphone frequency point, the acceptance of inadequate batteries, and the noise generated by the equipment during long-term operation.
3. Finally, check the heating conditions of each equipment during full load operation and long time operation. The heating phenomenon of each equipment to a certain extent will not affect the use of equipment and the safety of the system and equipment. However, if the installation does not retain the appropriate cooling space, or the equipment itself in a long time, heavy load operation of the poor heat dissipation, it should be solved, otherwise the light equipment has protection, heavy equipment damage.
In addition, it is necessary to add that: generally in the simulation run under different loads, different time system trial run, to further check the safety and stability of the system.
In short, the simulation of video conferencing system is very important and necessary work, at this time each job will be the long-term operation of the equipment and the security of the system. Especially the heating status of power supply lines and equipment will directly affect the safety of the project, so all engineering and technical personnel should attach great importance to it.
Four, debugging results and records of problems
There are many items to be debugged, set up and checked in sound engineering. These results and problems are important reference materials for future use and maintenance. It is necessary to record the results and problems in every step of work and make necessary analysis and summary. Record data that are useful to users should be handed over to them, and data that are useful for future maintenance should be properly kept by the designer.
