High-reliability system monitoring method and system

Abstract

The invention discloses a high-reliability system monitoring method and system, which are applied to data collecting equipment. The data collecting equipment comprises a CUP (central processing unit) module and an MCU (micro control unit) module, wherein a process monitoring module is arranged in the CPU module. The method comprises the following steps that the process monitoring module obtains the operation state data of each work process in the CPU module, and judges the data; the process monitoring module sends a reset instruction to work processes corresponding to the data exceeding a preset normal range; the process monitoring module obtains self operation state data and timely sends the self operation state data into the MCU module; if the MCU module does not receive the data sent by the process monitoring module within specified time or the received data exceeds the preset normal range, a reset instruction is sent to the CPU module by the . The method and the system have the advantages that the multiplex monitoring protection on the CPU module and the work processes of the CUP module is realized in software and hardware modes, and the work stability and the work reliability of the CPU module are ensured.

Description

technical field [0001] The invention relates to the field of system monitoring and management, in particular to a system monitoring method and system with high reliability. Background technique [0002] Generally, high-performance data acquisition devices use advanced embedded CPUs and run embedded operating systems. At present, CPUs such as ARM / X86 are generally used in the market, with a bus width of 32 bits or even higher, a running speed of hundreds of megabytes to several gigabytes, a complex internal structure, and strong computing power. When such a complex CPU is selected as the main control unit of the system, it is often necessary to load various operating systems, referred to as OS, such as embedded Linux, Win CE, Android, VxWorks, etc. This type of operating system is generally powerful and has a very complex structure. In order to achieve effective management of various resources, and to be able to run applications developed by users to achieve specific functio...

Problems solved by technology

However, the OS can only recognize the abnormality of the process in terms of resource usage, and cannot identify the abnormality of the process in terms of task execution.

[0005] Generally speaking, such systems also use internal or external watchdogs to solve such reliability problems, but watchdogs can only identify system main process exceptions and system crashes, and cannot further identify more specific exceptions, so many times not very good
