When being played back, since the data volume of the Wave data of storage is big, and the source for all Wave datas for needing twi-read to store
Code data simultaneously press the playback that Wave data could be completed after certain length sequence intercepts, so that needing to make when waveform playback data
With most system resource, when user misoperation, is easy to cause system for computer stuck or system crash, needs simultaneously
User falls into a long wait, thus bring user experience effect difference problem.In order to solve the above problems, the embodiment of the present invention
A kind of data processing equipment is disclosed, which can be carried on the achievable data such as host computer, data analyzer
The equipment of processing.
The embodiment of the present invention provides a kind of data processing method, and referring to Fig. 1, the above method includes at least following steps:
Step S101: target TDMS text is searched from Technical Data Management stream TDMS file based on message playback instructions information
Part.
In step s101, each TDMS (Technical Data Management Streaming, technical data pipe
Reason stream) file includes: the message sequence number group for being stored with message sequence number, is stored with the message data group of message data, it stores
There is the Wave data group of Wave data；Message sequence number, message data and the Wave data stored in each TDMS file comes
The identical bus message in bus data；In each TDMS file, the message sequence number in message sequence number group is right simultaneously
It should be used as the other channel name of message data group and the other channel name of Wave data group.
User has stored in TDMS file selection with to the corresponding TDMS file of waveform playback data all, and user selects
Message playback instructions information is generated after the completion, and message playback instructions information is used to characterize the playback road of the TDMS file of user's selection
Diameter, target TDMS file are the TDMS file of user's selection.In practical applications, the TDMS file that user selects each time
Number can be different, such as can be 1,2,3,4,5.
Wherein, TDMS file is the recording channel name in a manner of binary, i.e. the other channel name of message data group and waveform
The other channel name of data group is recorded in a manner of binary.
It should be noted that since bus data is to be made of multiple bus message, and carry out to each bus message
After unpacking, message sequence number, message data and the Wave data of each bus message can be obtained, in multiple bus message,
Message data and Wave data may exist identical, but the message sequence number of each bus message is then unique.Will be total
When line message is stored in TDMS file, since the label informations such as group name, channel name can be set in TDMS file, because
This, can use " message sequence number+message data ", and " message sequence number+Wave data " mode to message data and waveform
Data are stored.Specifically, being respectively combined by unique message sequence number to message data and Wave data, group is obtained
Message data and combined waveform data are closed, then combined message data and combined waveform data are stored.
And be read out for the ease of Wave data of the later period to storage, in storage combined message data and composite wave figurate number
According to when, be all with message sequence number for index grouping do not store, when needing to obtain Wave data, index messages serial number need to be first passed through
The corresponding message data of the message sequence number is read, then the message sequence is read by the message data index messages serial number that user selects
Number corresponding Wave data.
The specific storing process of combined message data is the message sequence number for indexing combined message data, and message sequence number is same
The other data of Shi Zuowei message sequence number group and the other channel name of message data group, and using message data as message data group
The data of corresponding channel under one's name are stored in TDMS file.Wherein, correspondence here refers to: any in message data group
Message sequence number and message data itself used in the channel name of message data derive from same bus message.
And the specific storing process of combined waveform data, then it is the message sequence number for indexing combined waveform data, by message sequence
Message sequence number under number group is corresponding logical as Wave data group as the other channel name of Wave data group and Wave data
The data of road under one's name are stored in TDMS file.Wherein, correspondence here refers to: in Wave data group, any waveform number
According to channel name used in message sequence number and Wave data itself derive from same bus message.
By the storing process of combined message data and combined waveform data, guarantee that is stored in each TDMS file disappears
Serial number, message data and Wave data are ceased from identical bus message in bus data.In this way, disappearing in each TDMS file
Cease the message sequence number in serial number group, the Wave data in message data and Wave data group in message data group
It is quantitatively identical, and is one-to-one.
Step S102: all message datas stored in target message data group are read.
It should be noted that target message data group is the message data group that target TDMS file includes.Therefore, it looks into
After finding target TDMS file, so that it may find target message data group in target TDMS file.
Due to being stored with message data in target message data group, by executing step S102, mesh can be read
All message datas stored in mark message data group.
Step S103: the channel name for the message data that user selects in target message data group is obtained, and utilizes and obtains
The channel name and target message serial number group taken indexes to obtain message sequence number corresponding with the message data of user's selection.
In step s 103, target message serial number group is the message sequence number group that target TDMS file includes.
It should be noted that the message sequence number in message sequence number group corresponds to simultaneously to be made due in each TDMS file
For the other channel name of message data group and the other channel name of Wave data group, and message data is in target message data group
Therefore data obtain the channel name of message data that user selects in target message data group, can use and get
Channel name and target message serial number group index to obtain message sequence number corresponding with the message data of user's selection.
Step S104: the obtained message sequence number corresponding channel of index under one's name all are read from target waveform data group
Wave data, and shown being played back after the Wave data read parsing.
In step S104, target waveform data group is the Wave data group that target TDMS file includes.
It should be noted that the message sequence number in message sequence number group corresponds to simultaneously to be made due in each TDMS file
It therefore can be by message sequence number in Wave data for the other channel name of message data group and the other channel name of Wave data group
The Wave data of message sequence number corresponding channel under one's name is read in group.And what is stored under target waveform data group is target wave
Therefore graphic data can get the message sequence number corresponding channel that step S103 index obtains under target waveform data group
All Wave datas under one's name.Then it plays back and shows after by the Wave data read parsing.
The embodiment of the present invention is by searching mesh from Technical Data Management stream TDMS file based on message playback instructions information
Mark TDMS file；Read all message datas stored in target message data group；User is obtained in target message data group
The channel name of the message data selected in not, and using the channel name of acquisition and target message serial number group index to obtain and user
The corresponding message sequence number of the message data of selection；It is corresponding logical that the message sequence number that index obtains is read from target waveform data group
All Wave datas of road under one's name, and shown being played back after the Wave data read parsing.The technical side of the embodiment of the present invention
Case can directly read mesh under the corresponding target TDMS file of message playback instructions information when user needs waveform playback data
All message datas stored in mark message data group, after user selects message data, using selected message count
According to channel name and target message serial number group index to obtain message sequence number corresponding with the message data of user's selection, and according to
It indexes obtained message sequence number and obtains Wave data from target waveform data group, finally play back the Wave data read
It shows.Whole process is without reading whole Wave datas, so system resource utilization rate is low, one side computer can
While other operations are responded, after user misoperation, Wave data also need to be only reselected, system card is not will cause extremely or is
System collapse, when on the other hand also substantially reducing user's waveform playback data latency without reading whole Wave datas repeatedly
Between, to improve user experience effect.
As shown in Fig. 2, all TDMS files by depositing in advance disclosed in above-described embodiment in a kind of data processing method
Storage bus data obtain, all pre-stored processes of TDMS file the following steps are included:
Step S201: bus data is obtained, and processing of unpacking is carried out to bus data, obtains disappearing for each bus message
Cease serial number, message data and Wave data.
It should be noted that unpack processing to bus data as the prior art.Since bus data is disappeared by a plurality of
Breath is constituted, and includes message sequence number, message data and Wave data in each bus message.Therefore, to bus data into
Row is unpacked after processing, message sequence number, message data and the Wave data of available each bus message.In multiple bus
In message, each message sequence number is all unique.
Step S202: the message sequence number of each bus message and message data group are combined into one-dimensional character string dimension and added
Enter the first storage queue, the message sequence number of each bus message and Wave data group are combined into one-dimensional U32 array and are added the
Two storage queues.
It should be noted that one-dimensional character string dimension and one-dimensional U32 array are all a kind of data types, one-dimensional character string number
Group indicates the sequence combination of several character strings, and one-dimensional U32 array then indicates 32 data without sign carry out sequence combinations.
The one-dimensional character string dimension that the message sequence number and message data of each bus message obtain, as combined message number
According to, and the message sequence number of each bus message and Wave data group are combined into one-dimensional U32 array, as combined waveform data.
In the step, the message sequence number of each bus message and message data group are combined into one-dimensional character string dimension and are added
The message sequence number and Wave data group of first storage queue and each bus message are combined into one-dimensional U32 array and the second storage are added
Queue is stored.
Step S203: the one-dimensional character string dimension of each of the first storage queue is read, and in each one-dimensional character string number
Message sequence number is indexed out in group.
It should be noted that being to be combined into one-dimensional character string number with message sequence number and message data group in the first storage queue
What group was added, and when being stored to one-dimensional character string dimension stored to entire one-dimensional character string dimension, therefore
Need first to read the one-dimensional character string dimension of each of first storage queue, and at the time of reading, in each one-dimensional character string dimension
In index out message sequence number.
Step S204: the message sequence number group message sequence number indexed out being stored in TDMS file.
It should be noted that being the message needed using in message sequence number group due to when reading message data in the later period
Serial number goes to read the Wave data of Wave data group corresponding channel under one's name, therefore, in storage, should index out step S203
Message sequence number be stored in the message sequence number group in TDMS file.
Step S205: being stored in the message data group in TDMS file for the message data in one-dimensional character string dimension,
And the channel name of each message data in the message data group is named according to the message sequence number indexed out, each message data
Itself and its channel name belong to same bus message.
It should be noted that in order to guarantee to return required for the later period can find user according to the selected message data of user
The Wave data put, therefore, it is necessary to which first message data is stored under the message data group in TDMS file, and by the message
The channel name of each message data is named according to the message sequence number that step S203 is indexed out in data group, and each message data
Itself and its channel name belong to same bus message.
Step S206: the one-dimensional U32 array of each of the second storage queue, and the rope in each one-dimensional U32 array are read
Draw message sequence number.
It should be noted that being to be combined into one-dimensional U32 array with message sequence number and Wave data group in the second storage queue
It is added, and when being stored to one-dimensional U32 array, it is to need first to read the one-dimensional U32 number of each of second storage queue
Group, and message sequence number is indexed out in each one-dimensional U32 array.
Step S207: the Wave data in one-dimensional U32 array is stored in the Wave data group in TDMS file, and will
The channel name of each Wave data is named according to the message sequence number indexed out in the Wave data group, each Wave data itself
Belong to same bus message with its channel name.
It should be noted that the message sequence number in message sequence number group corresponds to simultaneously to be made due in each TDMS file
It is according to message count for the other channel name of message data group and the other channel name of Wave data group, and when reading Wave data
Message sequence number corresponding to channel name according to message data selected by user in group reads corresponding channel name in Wave data group
Under Wave data, therefore, in the Wave data group being stored in the Wave data in one-dimensional U32 array in TDMS file
When, the channel name of Wave data each in Wave data group is named according to the message sequence number that step S206 is indexed out, is made every
A Wave data itself belongs to same bus message with Wave data channel name.
Step S208: whether the data volume of stored Wave data is more than preset value in inquiry TDMS file, if it is not, then
Step S209 is executed, if so, thening follow the steps S210.
It should be noted that being to be stored in the Wave data in one-dimensional U32 array when being stored to combined waveform data
Wave data group, since the data volume of the other Wave data of Wave data group is larger, if by the other waveform number of Wave data group
It according to being stored in a TDMS file, will lead to that TDMS file is excessive, played back to the Wave data in the TDMS file
When, it can be because Wave data amount causes greatly waiting time when waveform playback data longer, it has not been convenient to read.Therefore, to make text
Part size is suitable, convenient reading, and the Wave data amount that can be stored to each TDMS file controls.Specifically, to waveform
When data store, whether the Wave data amount that can first inquire in TDMS file is more than preset value.In practical applications, preset value with
Convenient reading is standard setting.
Step S209: the stored waveform data in TDMS file.
Step S210: new TDMS file storage bus data is established.
It should be noted that since the Wave data amount stored in each TDMS file is limited, and Wave data needs entirely
Portion is stored, to constitute the integrality of Wave data, therefore, it is necessary to establish the bus data of new TDMS file storage, from
And guarantee the integrality of Wave data, and when playing back to Wave data, avoid the data volume because of Wave data excessive
User is caused to fall into a long wait.
Optionally, process is stored in advance in all TDMS files, can also include:
To the wave in the message sequence number indexed out, message data and one-dimensional U32 array in one-dimensional character string dimension
When graphic data is stored, when the N number of message sequence number of every accumulation, N number of message data and N number of Wave data, once stored.?
In practical application the value of N can flexible setting according to actual needs, such as may be configured as 100,200.
It should be noted that once being deposited after N number of message sequence number, N number of message data and N number of Wave data will be accumulated
