Reset detection circuit for improving fault positioning efficiency of complete machine equipment

The invention relates to a reset detection circuit for improving the fault positioning efficiency of complete machine equipment. The reset detection circuit comprises a central processing unit CPU, aCPU reset detection circuit and a power supply reset detection circuit, wherein the CPU is respectively connected with the CPU reset detection circuit and the power supply reset detection circuit; theCPU reset detection circuit is used for monitoring a dog feeding signal output by a CPU, storing a first state value representing that the dog feeding signal is abnormal if the dog feeding signal ismonitored to be abnormal, and triggering the CPU to reset; the power supply reset detection circuit is used for monitoring the power supply voltage, and if it is monitored that the power supply voltage is abnormal, a second state value representing that the voltage is abnormal is stored; and the CPU is used for determining a reset reason of the CPU according to the first state value and the secondstate value.
