The redundant monitoring and display terminal (HMI-12C-06) uses the Linux operating system and

supports system self-checking, status monitoring, clock synchronization and display, Ethernet and

other functions. It supports processor and power redundancy functions. When there is a problem

with the processor part or the power supply, it can switch to the backup processor and power

supply to improve product reliability. It uses a 12-inch capacitive touch screen and is mainly used in

the high-reliability rail transportation industry.
