Problems solved by technology

[0005] 1. This method puts forward higher requirements for the design of the board, requiring the board to have two processors, because the price of the processor is generally higher, which undoubtedly increases the device cost and R&D cost of the board design;
[0006] 2. This method can only record the current loopback test results on site and report them to the background. Once a board has a serious fault or the time is urgent, it can only be solved by replacing the board. At this time, all online test messages will not If it is not saved, it will be impossible to locate the fault after the board is returned to the manufacturer
However, when a board fails and needs to be replaced, the few logs retained on the board will not be able to provide powerful help for offline fault location or board repair

Embodiment Construction

[0037] A single board fault location auxiliary device and positioning method according to the present invention, its core is to add a special non-volatile memory chip on the single board, such as FLASH can be used, cooperate with the test function on the single board, the single board The operating status information (including fault information) is stored in the non-volatile memory chip to avoid information loss due to power failure and other reasons. It is suitable for online, offline or remote fault location of single boards.

[0038] The specific implementation of a single board fault location auxiliary device described in the present invention is as follows: figure 1 Shown: includes: non-volatile storage module, storage information output module and running status test module, running status testing module tests the running status of the single board, obtains the running status information of the single board, and stores it in the non-volatile storage module. And the sto...

Abstract

The present invention relates to a single board fault location auxiliary device and its location method. Said invention is mainly characterized by that on the single board a removable special-purpose nonvolatile storage chip is added, said chip can be matched with test function on said single board, the running state information (including fault information) of said single board can be stored in the nonvolatile storage chip so as to prevent the information from losing due to causes of powerfail, etc. Said invention is applicable to on-line, off-line and remote fault location.

Description

technical field [0001] The invention relates to the field of electronic technology, in particular to a single board fault location auxiliary device and a location method. Background technique [0002] Now that we have entered the information age, the stability of the communication system is of great significance to people's production and life. If the communication system breaks down, it will often cause great inconvenience and even huge losses. Due to the specificity and timeliness of the operation of the communication system, the rapid location of faults is an important part of the communication system function. The fault location of end-to-end communication can be divided into line fault and equipment fault. During the operation of the board, faults may occur due to human or natural reasons. Therefore, in order to reduce the impact of faults on system operation, the board test function under online conditions should be provided. It is necessary to quickly confirm whethe...
