It will be apparent, however, to one skilled in the art that the present application may be practiced in other embodiments that depart from these specific details. In other instances, detailed descriptions of well-known systems, devices, circuits, and methods are omitted so as not to obscure the description of the present application with unnecessary detail.
In order to illustrate the technical scheme of the invention, the following description is made by specific examples.
Fig. 1 is a schematic implementation flow chart of a fault recording data processing method according to an embodiment of the present invention, and for convenience of explanation, only a portion relevant to the embodiment of the present invention is shown. The execution body of the embodiment of the invention can be a terminal device. As shown in fig. 1, the method may include the steps of:
s101: and reading waveform data obtained by fault wave recording, and storing the read waveform data in a shared memory.
In the embodiment of the invention, the waveform data obtained by fault recording can be read from the fault recording device in real time, and the waveform data read in real time is stored in the shared memory.
The shared memory can store and display single waveform data, and each waveform data corresponds to one waveform. The fault recording device can record fault data in real time, store a certain number of fault waveform data to be read and displayed, for example, record corresponding waveform data when faults occur. Alternatively, the fault-logging device may be a digital signal processor (Digital Signal Processing, DSP).
Optionally, before storing the read waveform data in the shared memory, the method may further include:
and clearing the data in the shared memory.
In the embodiment of the invention, before the data is stored in the shared memory, the data in the shared memory is required to be cleared so as to ensure the accuracy of the data.
S102: when the waveform data reading is completed or interrupted, the waveform data stored in the shared memory are stored in a first file in a preset format according to the sequence of the reading time.
When the reading of the single waveform data is completed or the waveform data is interrupted for some reason, the single waveform data stored in the shared memory can be stored in the first file in a preset format according to the sequence of the reading time. That is, the waveform data in the first file is stored in the order of the reading time, the waveform data read first and the waveform data read later are stored.
The time for reading the certain waveform data may be the time for reading the certain waveform data from the fault recorder. Each piece of waveform data may include a read time, a fault code, a fault number, each channel data, and the like. The file in the preset format may be a file with an extension of csv, i.e. the first file may be a file with an extension of csv.
Optionally, determining whether the read waveform data is completed by determining whether the number of points of the read waveform data reaches a preset sampling number; if the number of the read waveform data is equal to the preset sampling number, judging that the waveform data is read; if the number of the read waveform data is smaller than the preset sampling number, judging that the waveform data is not read.
Optionally, the fault recording data processing method provided by the embodiment of the invention can be applied to a Linux operating system.
As can be seen from the above description, the waveform data obtained by storing fault record in the mode of combining the file and the shared memory according to the embodiment of the invention can solve the problems that the shared memory cannot meet the storage requirement and has poor expansibility when the data size is large because the shared memory is limited in space and cannot be suitable for application scenes with large data size, and the mode of combining the file and the shared memory is used for storing the data and using the file as a data carrier for transferring can realize the matched storage of the volatile storage medium and the nonvolatile storage medium, can adapt to application scenes with large data size, has good expansion compatibility, has stability compared with the storage of waveform data by only using the shared memory, and can enhance the reliability of codes.
In an embodiment of the present invention, after step S102, the fault record data processing method may further include the following steps:
if the number of waveform data stored in the first file is larger than the first preset number, deleting the waveform data of a second preset number stored first in the first file, wherein the second preset number is smaller than the first preset number.
In the embodiment of the invention, when the number of waveform data stored in the first file is greater than the first preset number, the waveform data of the second preset number stored first in the first file can be deleted. Because the waveform data in the first file are all stored according to the sequence of the reading time, the first stored waveform data with the second preset quantity is deleted, namely the waveform data with the second preset quantity before the reading time is deleted. The first preset number and the second preset number can be set according to actual requirements, but the second preset number is smaller than the first preset number. For example, since the DSP stores 120 single-module waveforms at maximum and the human-machine interface (Human Machine Interface, HMI) stores 130 single-module waveforms at minimum, the first preset number may be set to 150 and the second preset number may be set to 20, and when the number of waveform data in the first file is greater than 150, the first stored 20 waveform data are deleted. Wherein the HMI may be used to display waveform data.
As can be seen from the above description, in the embodiment of the present invention, if the number of waveform data stored in the first file is greater than the first preset number, the second preset number of waveform data stored first in the first file is deleted, and the second preset number is smaller than the first preset number, so that when the number of data is too large, redundant data in the first file can be deleted, so that the required data can be searched in the first file later.

If the first file stores the complete waveform data to be displayed, the waveform display is performed based on the data in the shared memory, so that the complete waveform data to be displayed stored in the first file can be directly stored in the shared memory, and the waveform display is performed based on the complete waveform data to be displayed stored in the shared memory, so that the waveform display process is finished without executing steps S204 to S206.
Optionally, in S203, before storing the read complete waveform data to be displayed in the shared memory, the method may further include:
and clearing the data in the shared memory.
S204: if the first file stores incomplete waveform data to be displayed, the incomplete waveform data to be displayed is stored in the shared memory, and the incomplete waveform data to be displayed stored in the first file is deleted.
If the process of reading the waveform data to be displayed from the fault recorder is interrupted, the first file will store incomplete waveform data to be displayed.
If the first file stores incomplete waveform data to be displayed, the incomplete waveform data to be displayed is first stored in the shared memory, then the incomplete waveform data to be displayed in the first file is deleted, and then step S205 is performed.
Optionally, in S204, before storing the incomplete waveform data to be displayed in the shared memory, the method may further include:
and clearing the data in the shared memory.
S205: and reading the residual waveform data to be displayed from the fault wave recording device, and storing the read residual waveform data to be displayed in a shared memory, wherein incomplete waveform data to be displayed and residual waveform data to be displayed form complete waveform data to be displayed.
And continuing to read the rest part of the waveform data to be displayed from the fault wave recording device, namely, continuing to read the rest waveform data to be displayed at the interrupted position, storing the rest waveform data to be displayed read in real time in a shared memory, and continuing to execute the step S206. In the shared memory, the incomplete to-be-displayed waveform data stored in advance and the read residual to-be-displayed waveform data form complete to-be-displayed waveform data.
S206: and performing waveform display based on the complete waveform data to be displayed stored in the shared memory, and storing the complete waveform data to be displayed stored in the shared memory into the first file according to the sequence of the reading time.
