Hardware watchdog design

For Outdoor 4G Wireless CPE applied in key fields such as industrial automation and remote monitoring, “always online” is its most fundamental and important requirement. Any offline event caused by software crashes, program crashes or network anomalies may result in significant economic losses or security risks. ComFi W2140 deeply understands this point and has introduced a dual guarantee mechanism of “hardware watchdog” and “software watchdog” for this purpose.

Software watchdog: This is a monitoring program that runs at the operating system level. It will regularly check the status of key system processes and network connections. Once a process is found to be unresponsive or the network connection is interrupted, the software watchdog will attempt to restart the process or redial the network connection to self-repair.
Hardware watchdog: This is a hardware circuit independent of the main CPU. It is even more “impartial” and will wait for the “feeding dog” signal from its own CPU within the set time interval. If the main CPU fails to send signals on time due to a serious failure (such as a system freeze or program crash), the hardware watchdog will consider the system completely paralyzed and will not hesitate to force a restart of the entire device.
This “soft and hard combined” design builds unparalleled reliability for the ComFi W2140 Outdoor 4G Wireless CPE. The software watchdog is responsible for handling regular and recoverable faults, while the hardware watchdog serves as the last line of defense against the most extreme system crashes. The two work in coordination to achieve automatic fault detection and recovery, ensuring that the equipment can operate continuously for 7×24 hours, truly meeting the industrial-grade standards of unattended operation and high reliability.
