3. Fault alarm
The monitoring system generates three types of alarm and warning according to the nature of equipment failure:
Level 1 alarm: information alarm involving driving safety.
Complete reproduction
Secondary alarm: information alarm that affects the normal operation of driving or equipment
Three-level alarm: electrical characteristics exceed the limit or other alarm.
Early warning: Make logical judgment and early warning according to the trend of electrical characteristics, equipment status and application trend
