Service single board, fault detection and reporting method and system thereof

Abstract

The invention provides a fault detection and reporting method. The method comprises the following steps that: A. a service single board determines a working state of a power supply module through continuously detecting whether output voltage values of each voltage module are in a normal scope and if the power supply module works abnormally, a signal D possessing a first frequency is output; B. if the D signal of the first frequency is detected, a main control board determines that there is a fault in the voltage module. The invention also provides fault detection and reporting system and a service single board. By using the scheme of the invention, various fault detection and reporting can be realized so that reliability and security of communication equipment operation can be substantially raised.

Description

technical field [0001] The present invention relates to the technical field of communication equipment, in particular to a service single board, and a fault detection and reporting method and system. Background technique [0002] With the continuous expansion of the communication network scale and the continuous improvement of user needs, it not only requires the comprehensive management of the communication equipment business, but also puts forward higher requirements for the security and reliability of the communication equipment itself. This requires real-time detection of various fault states of the equipment (including service alarms, power module failure, key IC device failure, CPU failure or restart, backplane communication bus interface damage, etc.), and timely reporting to the network management platform. [0003] In the prior art, it is mainly to use the access of the CPU on the service single board to the key integrated circuit (IC) device to realize the fault de...

Problems solved by technology

[0004] The single-board fault detection and reporting methods in the prior art have great limitations, which are specifically reflected in: there is no detection of power module faults, once the power module of a non-critical IC device fails or the power module of a key IC device is in failure In the boundary state, the voltage drops, but the device is still in the normal working state, the existing method cannot detect, and in the failure of communication equipment, the failure of the power module is one of the failure causes that easily lead to serious consequences such as burning the board
