With the continuous development of technology and media technology, as a new modern teaching and learning model, multimedia electronic education systems have injected new vitality into the education industry. Recently, the Air Force Engineering University adopted the Dalian Kodi Kd-MF-72 high-definition multi format hybrid matrix, achieving the comprehensive application of new technologies such as multifunctional classrooms, multimedia teaching, diversified media demonstrations, and fully automatic control that modern teaching should have.

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.

The successful application of Dalian Kedi Kd-MF-72 high-definition multi format mixed matrix has brought great convenience to the teachers and students of Air Force Engineering University. Not only does it efficiently complete various teaching tasks, but it also achieves perfect switching between various signals with its high reliability and stability, fully utilizing the system's functions, greatly optimizing the utilization of teaching resources, and receiving strong praise from users.
