Project Name: Qinhuai District (formerly Baixia) Jinling Secondary Conference Room Audio and Video System Integration

Project implementer: Nanjing Jintu Digital Demonstration System Co., Ltd.

First, the specification

According to the characteristics of the project and the human resources of the company, a project team capable of meeting the project management needs will be established. Organize the construction preparation meeting attended by the project department and related personnel, fully understand the technical function requirements and other special requirements of the school according to the engineering characteristics and the site environment, carefully digest the design plan, clarify our specific responsibilities, and the construction details and construction progress. Make detailed arrangements. As far as possible, it is necessary to ensure that the schedule is completed in advance and there is room for it. All equipment must be carefully inspected when unpacking to ensure quality. Strictly control the construction quality. Safety is the first principle in the construction process.

Keep in touch with the school at any time, communicate with the school on the details of the project, and discuss ways to solve the problem. All the company involved in the project are on-site service, and subject to school arrangement and scheduling, all of which are responsible for the timely and high-quality completion of the entire project.

In addition, we are actively working with the decorating team responsible for the project. During the construction of the decoration company, our team will follow up in time and cooperate with each other. For example, during the construction process, all electrical control lines and lines of the other party must be PVC pipe; the same circuit wire should be laid in the same pipe, the wire diameter is appropriate, and the number of pipes to be piped should be no more than the cross-sectional area of ​​the PVC pipe. 40% of the cross-sectional area, the wire bending degree shall not be greater than 90 degrees, when the temperature exceeds 90 degrees, the pipe joints shall be connected; when the wires are worn, the strength must be separated, and the pipes are all worn, so that the joints are firm and reliable, and the insulation performance is good (the resistance is greater than 0.5MΩ).

After the completion of the project, in order to ensure safe and reliable operation of the equipment and easy operation and maintenance, we train a group of qualified maintenance and management personnel for the user. We are responsible for providing technical training. After the completion of the overall commissioning work, we set up a technical training class to conduct operational business technical training for the operators (number of users arranged by the user). The content covers safety practices, daily application operations, and so on.

Second, professional articles

As a complete multi-functional conference system solution, not only must there be high-quality conference system equipment, but also the integration of system functions, such as large-screen, large-screen graphics processor and other multimedia equipment, but also a strong central control The system manages and coordinates the actions of various devices.

In the design of this project, in order to realize the functions of conference room general meetings and multimedia conferences such as audio and video conferences, to meet the requirements of simple and smooth conference process, realistic and vivid hearing effects, clear and comfortable video display, etc., we have been based on many years of construction. Experience and make a clear plan for the project.

The whole system is roughly divided into display, pickup and sound reinforcement, signal transmission and lighting. It consists of large-screen display, liquid crystal display, audio, multimedia video source matrix switching and central integrated control, lighting and control. All signal switching and assignment are performed on the iPad.

With the rapid development of information technology, a large number of electronic devices are integrated into conference rooms, making the functions of modern conference systems more and more powerful, more and more devices need to be operated, and the requirements for specific operators are getting higher and higher. It is a big problem for the operator to quickly grasp the use of the conference system. But with the advent of centralized control systems, this problem has been solved. At the same time, the centralized control system also drives the corresponding changes of other subsystems in the conference system, making its system configuration and equipment selection more suitable for centralized control systems.

The video matrix (A/V matrix) is controlled by the serial port (RS232 interface) of the host to automatically select the image of the computer to be output to the projector, and the switching between the video signals is performed by the control software on the iPad. Through the serial port behind the host (RS232/RS422/RS485 interface), the audio matrix is ​​controlled to control the sound level of each pickup. Through CNPCI-8 (8-way strong electric relay), it controls the power supply of conference room lighting and the notebook power on the conference table.

Third, innovative articles

With the rapid development of mobile Internet, mobile devices are becoming more and more intelligent and popular. It is possible to synchronize the mobile phone screen with the liquid crystal display device through similar products such as F-box, so as to prevent the data on the previous mobile phone from being led to the computer, and then The tedious and troublesome use of a computer to play files.

In the conventional central control system, the control panel is cumbersome and the operation interface is troublesome. The switching of each signal and the adjustment of the volume must be operated by the special personnel in the control room. In order to meet the requirements of simple operation and functional requirements, we will remove the old control panel and use the lightweight IPAD to cooperate with the Crestron wireless network. . The IPAD control device is selected to integrate all peripheral, video matrix, audio processor and other functions into one. Through the host's serial port (R232 control interface), the original complex system operation integration can be simplified by operating a few buttons. When the equipment is commissioned, we can set and debug the actual needs of the user to the best state through the professional debugging software. When using, the user only needs to press the button to ensure that the device is operated by non-professionals. They all work at their best. Realize "professional equipment, fool-like operation". This simplifies the control process and makes the meeting more fluid.

During the construction process, we found that the table was inserted on the desktop, and the later wiring was inconvenient and the exposed wire would occupy the desktop area, which would affect the overall appearance. After repeated discussions with the school, we decided to insert the table on the side of the table. We chose products with good quality, high integration, non-modular, and excellent workmanship; we also made adjustments in terms of color in terms of aesthetics: from traditional white to dark colors that match the conference table. In this way, the device connection at the meeting is not affected, and the desktop area is not affected, so that the overall effect is very good.

In addition, in the standard screen, according to the conventional practice, it is generally set directly above the display large screen. However, due to the high floor height of the school conference room, if the conference screen is placed on the display screen, it will occupy the size of the large screen, which will affect the display and viewing effect. Therefore, our final approach is to place the monogram screen directly opposite the entrance of the conference room, so that it does not affect the use and allows the conference staff to see the theme or related content of the conference as soon as they enter the conference room.
