4.4 Hardware watchdog function introduction
This hardware product is designed with a hardware watchdog function. After the hardware
watchdog is powered on, it will automatically turn on and detect the heartbeat level output
by the routing system that jumps once per second. If the routing system itself fails (such
as a crash), it will also Naturally, the heartbeat level can no longer be output. At this time, if
the hardware watchdog does not detect the heartbeat level within 120 seconds, it will shut
down itself for 15 seconds and then restart the entire system.
When the routing system is operating normally, but the 4G module dialing is abnormal, the
routing system will control the 4G module's power supply and let the 4G module
automatically restart to repair the 4G dialing abnormal problem.
