Problems solved by technology

When an abnormality occurs in the embedded system, it often causes the processor to reset, but when the abnormal scene disappears, it is difficult to capture the cross-section information at the time of the abnormality, and the abnormality of the embedded system is closely related to the operating conditions and environment on site, so the abnormal phenomenon is not easy It is difficult to locate the cause of recurrence and abnormality, which may lead to hidden dangers in the operation of the device

Embodiment Construction

[0022] The technical scheme of the present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments, so that those skilled in the art can better understand the present invention and implement it, but the examples given are not intended to limit the present invention.

[0023] Such as figure 1 As shown, a method for displaying abnormal records of an embedded system includes the following steps:

[0024] Step 1, setting an abnormality monitoring module and an abnormality record storage module in the embedded system.

[0025] Add exception monitoring and exception record storage functions in program files, for example, register abnormal interrupts in the program initialization phase, and add abnormal record storage functions in abnormal interrupts.

[0026] During the program running phase, the exception types monitored by the processor generally include but are not limited to: hardware exceptions such as clock fa...

Abstract

The invention discloses a recording and displaying method for the exception of an embedded system. The method comprises the following steps that: S1: in the embedded system, setting an exception monitoring module and an exception recording and storing module; S2: when the exception monitoring module monitors that the embedded system is exceptional, triggering the exception recording and storing module, and giving an alarm; S3: recording an exception recording file; and S4: analyzing the recording file, and displaying the exception recording. By use of the method, the processor state information and the system operation information when the embedded system is abnormal are recorded on line, and the recorded file is selected to be read online or offline according to a device resetting situation. Then, the processor exception information is displayed so as to conveniently position exception reasons. A visual and accurate basis is provided for problem positioning, so that operation hidden dangers are eliminated in time, and system operation reliability is improved.

Description

technical field [0001] The invention relates to a method for displaying an abnormal record of an embedded system. Background technique [0002] With the continuous expansion of the functions of relay protection devices, the application of embedded processors in this field is also becoming more and more popular. When the embedded system is abnormal, it often causes the processor to reset, but when the abnormal scene disappears, it is difficult to capture the cross-section information at the time of the abnormality, and the abnormality of the embedded system is closely related to the operating conditions and environment on site, so the abnormal phenomenon is not easy It is difficult to locate the cause of recurrence and abnormality, which may lead to hidden dangers in the operation of the device. Contents of the invention [0003] In view of the above problems, the present invention provides a method for displaying abnormal records of an embedded system, which can quickly a...
