01.Stable operation configuration using Redundancy System design
If the MMI device's screen display malfunctions or input (touchscreen function) malfunctions occur during operation of a railway vehicle, normal operation is impossible. Therefore, a redundant system configuration has been applied to ensure safe operation of the vehicle even in the event of a malfunction or failure.
-
02.Application of 5-wire type touchscreen with improved reliability
The sensor life of the 5-wire resistive touchscreen is longer than that of the 4-wire type, and its durability and safety are far superior. In addition, its high sensitivity allows for accurate and efficient contact calculation.
-
03.Event log storage and log analysis using self-developed analysis program
Communication data with signal devices is stored as a log at regular intervals, and important information is stored separately for a longer period when an event occurs. You can easily check the constant log and event log with the signal device through USB download using the self-developed program.
