Problems solved by technology

Although this technical solution can temporarily solve the failure of the equipment, it cannot fundamentally solve the obstacles caused by the equipment and avoid the recurrence of the same failure.
[0005] From the above analysis, it can be seen that the disadvantages of the existing technology are: when the system or equipment fails, the user is accustomed to directly reset the system or equipment, and does not collect fault information during the reset period, and cannot locate the faulty equipment in time, which is inconvenient In the future, maintenance personnel or R&D personnel will fundamentally solve the fault problem

Embodiment Construction

[0029] The core of the present invention is to increase a non-shielding interrupt pin in the control unit (hereinafter will be illustrated with Complex Programmable Logic Device (CPLD, Complex Programmable Logic Device) as an example), and set the waiting time of system reset, and set all The waiting time described above is stored in the register of the complex programmable logic device. When an abnormality occurs in the system, the reset key is started, and the output reset signal is sent to the complex programmable logic device. When the complex programmable logic device detects the reset signal , send a non-maskable interrupt (NMI, Non maskable Interrupt) to the processor (CPU, Center Processing Unit) through the non-maskable interrupt pin; when the processor receives the non-maskable interrupt, it collects and stores the corresponding fault information (ie working state); the complex programmable logic device clears the non-shielding interrupt after reaching the preset wait...

Abstract

A method for resetting system includes presetting the waiting time of system reset, sending interruption request to CPU when reset signal is detected by control unit, receiving interruption request by CPU to collect and store fault data of relevant equipment, clearing off interruption request and resetting the system by control unit when waiting time of system reset is up . The device for realizing the method is also disclosed.

Description

technical field [0001] The invention relates to reset processing technology, in particular to a system reset processing method and device. Background technique [0002] With the continuous expansion of the network scale, there are more and more problems such as network congestion and disconnection, the probability of equipment failure is increasing, and the amount of fault data is also rapidly expanding. A network element failure may cause other systems to report a large amount of fault information, which brings great inconvenience to maintenance personnel in alarm location and fault diagnosis. [0003] In the current telecommunications field, artificial intelligence technology has been widely used in network management systems, such as rule-based event correlation description, fault location, etc. The rule-based fault information association and analysis mechanism can effectively use the built-in network model Correlation analysis of faults, early monitoring and diagnosis ...
