With the increasing development of urban transportation, subway transportation has become more convenient, and more and more people have chosen to take the subway. It is particularly important to comprehensively ensure the safety of this public area. Recently, the multi format mixed matrix of Cordi 72 Road has been successfully used in the Chengdu Metro Public Security Bureau, providing a safer and more comfortable travel experience for all passengers!

Dalian Kedi Kd-MF series high-definition multi format mixed matrix adopts FPGA array style 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.

As a leader in the fields of signal transmission, conversion, and processing, Dalian Kedi has won widespread recognition and good reputation from users with its strong technical strength, and further established its brand leadership position. We have reason to believe that in the future, Kodi will continue to lead innovative technology in the audiovisual field, providing more users with higher quality products and more humane services.
