The N+1 backup HDMI matrix is a backup broadcast control core device developed by Orivision Electronics specifically for the PIS (Passenger Information System) of the rail transit industry. The system adopts an N+1 redundant architecture design, which can automatically replace the fault signal with the set backup broadcast control host signal when any broadcast control host fails, achieving seamless switching between primary and backup in milliseconds, and maximizing the uninterrupted broadcast of real-time multimedia information such as boarding instructions and train operation information.
The highest device support 4K@30Hz Resolution input and output, backward compatible with 480i to 4K full format resolution, built-in line doubling technology intelligently optimizes image quality performance. Equipped with audio embedding/decoding synchronization processing capability to ensure perfect synchronization of audio and video signals. Designed with a 1U industrial grade rack, it has ± 8kV electrostatic protection and a wide temperature range of -20 ℃~60 ℃, suitable for harsh operating environments such as subways and high-speed trains.
Comprehensive coverage of matrix control system: supports front panel button operation (all operations and prompts can be fed back on the front panel LED screen), infrared remote control, RS232 serial port, TCP/IP network, web browser and other control methods. Adopting the B/S architecture WEB human-computer interaction interface, the PC side can control the device through the browser without installing any software or drivers. It also supports WEB remote firmware upgrade, greatly reducing operation and maintenance costs. Provide reverse code interface, which can be deeply linked with third-party broadcast control systems.
💡 Core advantages:N+1 redundant backup architecture+ 4K@30Hz Ultra clear broadcast control+millisecond seamless switching+full protocol remote control+B/S architecture WEB management - the best solution for 7 × 24-hour broadcast control guarantee of rail transit PIS system.
