Recently, Hubei Civil Air Defense purchased multiple hybrid matrices, VGA matrices, and RGB matrices from Dalian Kodi to comprehensively upgrade its video conferencing system to adapt to the rapidly developing technological environment and greatly improve work efficiency.

Dalian Kedi Kd-MF series high-definition and multi format hybrid matrix is a high-performance modular plug-in matrix system that can reach a scale of 288 × 288 and can flexibly configure input and output boards. Adopting FPGA array based pure hardware technology architecture: due to no hard disk, maintenance free, and no operating system, it avoids the problems of industrial control system crashes, hardware conflicts, blue screens, and computer virus intrusion; Moreover, the startup speed is fast (<20 seconds), stable and reliable, and unexpected power outages will not cause equipment damage. It can be operated frequently to switch on and off. The input and output boards adopt a modular rear panel structure, which can flexibly configure different signal formats and quantities; The power and control boards adopt a modular front panel structure with dual power and dual control redundant hot backup, which improves the stability of the equipment. This matrix also supports hot swapping, which allows online upgrades, maintenance, and expansion to be completed by simply replacing or adding cards without power outage or changing wiring. The integration of signal interface and signal board solves the process bottlenecks that affect signal quality, such as virtual soldering and missed soldering, and reduces the number of fault points in the matrix. The design of air-cooled noise reduction temperature control greatly improves the stability of the equipment.

The modular plug-in structure adopted by Dalian Kodi RGB matrix was first used by Kodi in China, adhering to the internationally advanced design concept of "front door plug-in structure, redundant dual power supply, and dual control system", completely solving the signal quality and production bottlenecks of large-scale matrices. Front door plug-in structure: supports live plug and unplug modules, and there is no need to replace the entire machine or change the system wiring after the device is mounted. Only the corresponding matrix module can be replaced to complete matrix maintenance and upgrading, greatly facilitating system failures, maintenance, expansion, etc. Redundant hot backup dual power supply: Adopting a redundant hot backup design, the matrix system's chassis adopts a hot backup integrated switch power supply, and the dual power modules in the chassis work simultaneously, serving as hot backup for each other. When one of the power components fails, the other power pack automatically assumes all power supply to the system, ensuring the continuity of system operation and greatly improving the reliability of the system. Dual control system: The dual control system can be selected according to requirements, and the matrix controls the control system as the main and backup. When the main control system fails, the backup control system continues to support system operation without affecting the switching operation of the matrix system.

The Kodi VGA matrix is a matrix specifically designed for transmitting high-resolution computer display signals, using two types of structures: modular board insertion and compact solidification. The matrix bandwidth is 400MHz~650MHz, and the signal format is compatible with various signal formats such as RGBHV, RGBS, RGsB, RsGsBs, YPbPr, S-video, etc. Matrix size 4 × 1~256 × 256, using field reverse switching, audio support balanced/unbalanced input/output, using RS-232, RS-422, RS-485, TCP/IP control. All technical indicators have been tested by authoritative departments and meet or exceed the Class A standard for broadcasting. It can adapt to uninterrupted working conditions of 7x24 hours, with an average time between failures exceeding 30000 hours, providing a stable and reliable signal transmission switching center for the system.

Electronic informatization is an important driving force for the continuous development of today's society. How to better utilize the convenience brought by technology to users is a question that Dalian Kedi is constantly thinking about. As a leader in the signal processing industry, Kodi will always stand at the forefront of technology, continuously increase research and development efforts, and provide users with more professional and valuable products and services.
