Abstract
The invention discloses an abnormality capturing and distributing method of an embedded operating system, which comprises the following steps that (1), a data acquisition and filtering module is established, and serial port data is acquired; (2), the data acquisition and filtering module filters acquired information, and obtains abnormal running information of application programs; and (3), the abnormal running information of the application programs is sent to corresponding application programs. According to the method, the abnormal information thrown out by the embedded operating system can be filtered by intercepting the serial port data, and distributed to the application programs to be processed, so that the application programs can analyze the abnormal information, and perform corresponding processing such as monitoring, protection and restart, and the embedded operating system can be more stable.
Description
Technical field
The present invention relates to a kind of embedded OS and catch the method unusual and distribution of grabbing.
Background technology
Embedded OS is in the process of operation, and intrasystem application program can take place inevitably that some are unusual, and is unusual normally because some of application program are not known what bright defective caused.Application program takes place when unusual, embedded OS is exported the unusual information of collecting usually by the mode of serial ports, and for the abnormal information that unusual application program itself can't the system of getting access to be dished out takes place, cause application program can't utilize abnormal information to take the stability of corresponding mistake proofing mechanism to improve.
Summary of the invention
In order to solve the defective that existing application can't obtain abnormal information, the invention provides a kind of embedded OS and catch and grab solution unusual and distribution.
A kind of embedded OS is caught and is grabbed method unusual and distribution, and may further comprise the steps: (1) sets up the data acquisition filtering module, and serial data is gathered; (2) the data acquisition filtering module filters the information that collects, and obtains application program operation exception information; (3) application program operation exception information is sent to corresponding application program.
The data acquisition filtering module sends to corresponding application program by unusual distribution driver module with application program operation exception information.
Described data acquisition filtering module communicates by Inter-Process Communication mode and unusual distribution driver module.
The performing step that application program operation exception information is sent to corresponding application program is:
(31) application program that need obtain operation exception is registered to unusual distribution driver module; (32) distribute unusually driver module with the application program of oriented its registration carry out record one by one; (33) distribute unusually and be distributed to registered application program after driver module is received application program operation exception information.
In sum; the present invention can filter the abnormal information that embedded OS is dished out by the data of intercepting serial ports, and is distributed to a plurality of application programs and handles; be conducive to application program analysis abnormal information and make corresponding processing the such as monitoring, protect, restart, make system more stable.
Description of drawings
In order to allow those skilled in the art can understand technical scheme of the present invention better, below the invention will be further elaborated.
Embodiment
The present invention has disclosed a kind of embedded OS and has caught the method unusual and distribution of grabbing.Usually, when the program of operation in the embedded system (calling system in the following text) takes place when unusual, system arrests unusual and generates application program operation exception information (calling abnormal information in the following text) according to corresponding agreement, and application program is directly to obtain this abnormal information, the present invention gathers serial data by setting up the data acquisition filtering module; The data acquisition filtering module can be a function in the serial port drive program, can intercept the data of serial ports, and the information that collects is filtered, and obtains abnormal information.
For the abnormal information data that will collect send to application program, when application program launching, if it need obtain operation exception, then register to unusual distribution driver module; Unusual distribution driver module with the application program of oriented its registration carry out record one by one; After the acquisition filter module collects abnormal information, communicate by letter with unusual distribution driver module by the Inter-Process Communication mode, application program operation exception information is sent to unusual distribution driver module, distribute unusually and be distributed to registered application program after driver module is received application program operation exception information.Application program can be handled the content according to abnormal information after receiving abnormal information accordingly.
Present embodiment is more excellent embodiment of the present invention, and the part that is not described in detail all adopts known mature technology.Need to prove; under the situation that does not deviate from spirit of the present invention and essence thereof; those of ordinary skill in the art work as can make various corresponding changes and distortion according to the present invention, but these changes and distortion all should belong to the protection domain of the appended claim of the present invention.
