Recently, the Kedi Kd-MF series high-definition multi format hybrid matrix has successfully passed the acceptance of the Hefei Civil Air Defense Ground Command Center project. In order to effectively carry out work, the system must quickly and flexibly dispatch information. On the one hand, it is necessary to have the ability to quickly switch signals and display multiple signals without affecting each other. At the same time, it is necessary to support the access of remote video conference signals, facilitate the rapid convening of meetings, and carry out emergency command work.

Dalian Kedi Kd-MF series high-definition multi format mixed matrix adopts FPGA array based pure hardware technology architecture: due to the lack of 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.

Dalian Kedi relies on years of industry practice experience, advanced products, and high-quality services to provide assistance for the upgrading and renovation of the Hefei Civil Defense Ground Command Center, and also contributes to the advancement of civil defense engineering to a new level of technology and intelligence.
