"Electronic fence" is actually a virtual "fence", which means that an area can be delineated by GPS positioning and vehicle data can be read. This setting is to prevent the fatigue driving of large trucks and dangerous goods vehicles and locate their GPS. If they are found to have been driving continuously for more than 4 hours and driving all day for more than 8 hours, they will remind drivers by phone or SMS, guide them to rest in the service area, and even carry out law enforcement investigation.
