System death alarm monitoring circuit and protection terminal equipment

The invention relates to the technical field of electronic circuits, and discloses a system death alarm monitoring circuit and a protection terminal device, the circuit comprises a first delay module, a first reset control module and a reset module; the reset module is used for transmitting a timing overflow signal to the first reset control module during software runaway; the first reset control module is used for generating a first reset control signal according to the timing overflow signal, and transmitting the first reset control signal to the reset module after being delayed by the first delay module; and the reset module is also used for generating a first reset signal according to the first reset control signal, delaying the first reset signal by the first delay module and then transmitting the first reset signal to the microcontroller to reset the microcontroller. After the first reset control module generates the first reset control signal according to the timing overflow signal generated by the res
