Abstract
The invention discloses a kind of embedded OS abnormality capturing and the method for distribution, comprise the following steps: (1) sets up data acquisition filtering module, is acquired serial data；(2) information collected is filtered by data acquisition filtering module, it is thus achieved that application program operation exception information；(3) application program operation exception information is sent to corresponding application program.The present invention can be by intercepting the data of serial ports; filter the abnormal information that embedded OS is dished out; and be distributed to multiple application program and process, beneficially application program is analyzed abnormal information and is made and be monitored, protect, the corresponding process such as restart, and makes system more stable.
Description
Technical field
The present invention relates to a kind of embedded OS abnormality capturing and the method for distribution.
Background technology
Embedded OS is during running, and intrasystem application program inevitably occurs some abnormal, and some being extremely often as application program do not know what bright defect caused.When application program occurs abnormal, embedded OS generally exports the abnormal information collected by the way of serial ports, and for occurring abnormal application program itself cannot get the abnormal information that system is dished out, cause application program that abnormal information cannot be utilized to take corresponding mistake proofing mechanism with the stability improved.
Summary of the invention
The defect of abnormal information cannot be obtained to solve existing application, the invention provides a kind of embedded OS abnormality capturing and the solution of distribution.
A kind of embedded OS abnormality capturing and the method for distribution, comprise the following steps: (1) sets up data acquisition filtering module, is acquired serial data；(2) information collected is filtered by data acquisition filtering module, it is thus achieved that application program operation exception information；(3) application program operation exception information is sent to corresponding application program.
Data acquisition filtering module drives module that application program operation exception information is sent to corresponding application program by abnormal distribution.
Described data acquisition filtering module drives module to communicate by Inter-Process Communication mode with abnormal distribution.
The step that realizes that application program operation exception information is sent to corresponding application program is:
(31) application program obtaining operation exception is needed to drive module to register to abnormal distribution；(32) abnormal distribution drives module that all application programs being registered with are carried out record one by one；(33) abnormal distribution drives module to be distributed to registered application program after receiving application program operation exception information.
In sum; the present invention can filter the abnormal information dished out of embedded OS by intercepting the data of serial ports, and be distributed to multiple application program and process; be conducive to application program to analyze abnormal information to make and be monitored, protect, the corresponding process such as restart, make system more stable.
Accompanying drawing explanation
In order to allow those skilled in the art can be best understood from technical scheme, below the invention will be further elaborated.
Detailed description of the invention
Present invention is disclosed a kind of embedded OS abnormality capturing and the method for distribution.Generally, when the program run in embedded system (calling system in the following text) occurs abnormal, system is arrested extremely and according to corresponding protocol generation application program operation exception information (calling abnormal information in the following text), and application program is to directly obtain this abnormal information, serial data, by setting up data acquisition filtering module, is acquired by the present invention；Data acquisition filtering module can be a function in serial ports driver, it is possible to intercepts the data of serial ports, filters the information collected, it is thus achieved that abnormal information.
In order to the abnormal information collected data are sent to application program, when application program launching, if it needs to obtain operation exception, then module is driven to register to abnormal distribution；Abnormal distribution drives module that all application programs being registered with are carried out record one by one；After acquisition filter module collects abnormal information, module communication is driven with abnormal distribution by Inter-Process Communication mode, application program operation exception information is sent to abnormal driving module of distributing, and abnormal distribution drives module to be distributed to registered application program after receiving application program operation exception information.Content according to abnormal information can be processed after receiving abnormal information by application program accordingly.
The present embodiment is the more excellent embodiment of the present invention, and the part not being described in detail all uses known mature technology.It should be noted that; in the case of without departing substantially from present invention spirit and essence thereof; those of ordinary skill in the art are when making various corresponding change and deformation according to the present invention, but these change and deform the protection domain that all should belong to appended claims of the invention.
Claims (1)
1. an embedded OS abnormality capturing and the method for distribution, it is characterised in that comprise the following steps:
