Abstract

The invention provides an equipment crash recovery method and device and a storage medium. The method and device are used for improving the success rate of equipment crash recovery. If the first watchdog timing module does not receive the first dog feeding signal when the first watchdog timing module is overtime, a processor in the equipment is indicated to reset, wherein the first watchdog timingmodule is used for receiving a first dog feeding signal sent by an application layer in the equipment; if the second watchdog timing module does not receive the second dog feeding signal when the second watchdog timing module is overtime, the whole board in the equipment is indicated to reset, wherein the second watchdog timing module is used for receiving a second dog feeding signal sent by a kernel layer in the equipment.

Description

technical field [0001] The present application relates to the technical field of communications, and in particular to a method, device and storage medium for recovering from device crashes. Background technique [0002] A processor is a relatively common component unit in a communication device. In order to prevent the communication equipment from crashing, etc., a corresponding watchdog is usually set in the communication equipment. When the CPU is running normally, it will send a feeding signal to the watchdog at a fixed cycle. After the watchdog receives the dog feeding signal, it restarts timing. If the watchdog does not receive the dog feeding signal within the preset time period, it will trigger a reset signal and the processor will reset. [0003] However, if there is a problem with other components in the device, it is difficult to restore the device only by resetting the processor.
