Embodiment Construction

[0034] The present invention will be described in further detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0035] Such as figure 1 As shown, the embodiment of the present invention relates to a system fault detection and processing method, including:

[0036] Step S101, the interrupt service program sends a first-level dog feeding signal, and receives a second-level dog feeding signal for the system detection task;

[0037] In this step, the interrupt service program is normally a first-level hardware feed dog (sends a first-level dog feed letter), when the system crashes the operating system or hardware is abnormal, the interrupt service program cannot work, and the hardware dog is automatically reset.

[0038] When the system starts, the interrupt service program starts the first-level hardware...

Abstract

The invention discloses a method and a device for detecting and processing system faults. The method comprises the following steps: sending a first-grade dog feeding signal by an interrupt service routine and receiving a second-grade dog feeding signal of a system detection task; when detecting a task endless loop or task exception, carrying out system exception handling according to a pre-set processing strategy; when the interrupt service routine cannot receive the second-grade dog feeding signal in pre-set time, stopping feeding the first-grade dog feeding signal by the interrupt service routine and restarting the system. According to the method and the device, automatic detection of faults of a software system can be realized and the system is automatically recovered according to a user strategy; the system exception of a system starting process and a system operation process can be detected simultaneously and is automatically recovered; exception types in an operation process of the system can be identified by classifying, and the exception judgment and self recovery can be carried out according to the user strategy; system exception detection and self-recovery strategies can be configured by a user; exception reasons can be recorded and can be inquired.

Description

technical field [0001] The invention relates to the technical field of software system fault detection and processing, in particular to a system fault detection and processing method and device. Background technique [0002] During the startup and operation of the software system, failures often occur that cause the system to fail to work, such as: system hardware hangs, operating system crashes, task exceptions, task endless loops, over-frequency interruptions, etc. For the communication system software, when the software system fails, it can automatically identify the abnormal state of the task, and according to the user's configuration strategy, perform corresponding abnormal fault alarms, records, and system recovery, which are all essential functions. Especially for those systems that support voice services that require high real-time performance, at any stage of system operation, when encountering any faults, it is required to be able to completely and accurately ident...
