Embodiment Construction

[0025] The present invention will be further described in detail below in conjunction with the accompanying drawings, so that those skilled in the art can implement it with reference to the description.

[0026] Such as figure 1 As shown, the present invention provides a method for automatically restarting and recovering from equipment failure. During actual use of the equipment, the utilization rate of the CPU will be at a relatively reasonable level. , then the device is not suitable for this occasion or has broken down. The present invention judges whether the equipment fails by continuously monitoring the CPU utilization rate of the equipment, and automatically restarts the equipment if the CPU utilization rate is found to be in a high state continuously.

[0027] Specifically include the following steps:

[0028] Step 1. Set the CPU utilization threshold value C according to experience 2 , polling time T 1 and duration threshold T 2 . For example, according to exper...

Abstract

The invention discloses a method for automatically restarting and recovering equipment failure. The method comprises that: the current duration T3 of a CPU is determined, and the current utilization rate C1 of the CPU is obtained; when C1 is smaller than C2, the equipment is normal, and after the polling time T1 is waited, the current duration time of the CPU is determined again, and the utilization rate of the CPU is obtained; when C1 is greater than or equal to C2, the equipment is abnormal, and the current duration time is updated to T3' : T3' = T3 + T1; when T3' is smaller than T2, the duration time of equipment abnormity does not reach the duration time threshold value, and the utilization rate of the CPU is obtained again; and when T3' is greater than or equal to T2, the duration of equipment abnormity reaches a threshold, and the equipment is restarted, wherein C2 is a CPU utilization rate threshold value, and T2 is a duration threshold value. According to the designed and developed method for automatically restarting and recovering the equipment fault, whether the equipment is abnormal or not is judged by monitoring the utilization rate of the CPU, and the equipment monitoring accuracy is improved.

Description

technical field [0001] The present invention relates to the technical field of equipment failure restart, and more specifically, the invention relates to a method for automatically restarting and recovering from equipment failure. Background technique [0002] The design idea of ​​traditional device fault recovery is: when the device is working normally, the CPU (core processor) always outputs the "feed the dog" signal, when the device fails, the CPU will stop outputting the "feed the dog" signal, and the watchdog circuit will Trigger system reset or restart the system by power off to restore the system to normal operation. However, in the actual use process, when many faults of the equipment occur, the CPU works normally and can always output the "feed the dog" signal, so it cannot trigger system reset or power-off restart for recovery. Contents of the invention [0003] The present invention designs and develops a method for automatically restarting and recovering from ...
