Technical Field

Background
An oscilloscope is a measuring instrument that converts an alternating electrical signal that cannot be directly observed by the human eye into a waveform and displays the waveform. The general mathematical operation needs to specify a plurality of physical channels, and the acquired data is operated into a new operation waveform by setting a formula, and in the operation rule, the channels participating in the operation and the constant parameters of the operation need to be set.
As shown in fig. 1, an oscilloscope in the prior art includes a plurality of acquisition circuits for acquiring data of a plurality of channels, a memory for storing the acquired data, a mathematical operation rule for performing mathematical operation processing on the data of a plurality of physical channels, and a new display waveform. The operation sources directly or indirectly used in the method are all physical signals acquired at the same time.
The operation source of the oscilloscope in the prior art is limited to the data acquired this time, or the measured value counted by the acquisition this time based on the physical channel. When mathematical operations are performed, in addition to directly configuring constants of numerical values, other parameters participating in the operations generally come from physical channels participating in the operations directly or indirectly. The source of the operation data is limited to the data from the same instrument and the data collected and reported at the same time.
When some complex mathematical operations are carried out, such as 3-phase power operation, 6 measurement sources must be accessed simultaneously. This means that the test must occupy 6 acquisition ports of the scope apparatus. As a result, the oscillographic device with only 2 acquisition ports cannot meet the test requirements. On the premise of ensuring the synchronism of multiple tests, the invention can divide one test into 3 sub-tests, wherein 4 paths of signals are converted into virtual channels in the first two tests, and 6 paths of signal mixing operation is realized in the 3 tests.

The following are detailed below.
Fig. 2 is a schematic structural diagram of an oscilloscope supporting an external data source according to an embodiment of the present application, and in the system, a specific structural composition of the oscilloscope for waveform data mixing operation is disclosed.
As shown in fig. 2, the oscilloscope supporting the external data source includes an acquisition circuit 201, a memory, a data parser 202, an operator 203, and a converter 204. The acquisition circuit 201 and the data analyzer 202 are both connected to the memory, the operator 203 is connected to the data analyzer 202, and the converter 204 is connected to the operator 203.
The acquisition circuit 201 is a physical device commonly used in oscilloscopes for acquiring waveform data, and can continuously and synchronously acquire and record waveforms of multiple channels and multiple signals, such as voltage signals, current signals, frequency signals, temperature signals, and the like, for a long time. The acquired waveform data can be stored in a memory medium or other memory media capable of being read and written quickly. In an embodiment, the acquisition circuit 201 is configured to acquire waveform data of the electrical signals of the channels.
In an embodiment, the memory is used for storing the acquired waveform data and a data file formed by processing the waveform data according to a preset processing rule. Preferably, the memory may include a memory 205 and a disk memory 206, the memory 205 is configured to store the acquired waveform data, and the disk memory 206 is configured to store a data file formed by processing the waveform data according to a preset processing rule. The memory 1205 is a storage medium for storing the waveform data acquired this time, wherein the stored content includes the acquired raw data and the measured value counted based on the raw data. The disk memory is a hard disk storage space on the oscillograph device, the embodiment is used for storing external operation source files, each stored data file can be regarded as an independent virtual channel, the storage position and the naming rule of the data file need to be set, and the number of the virtual channels owned by the equipment and the calling method are determined in a file scanning mode.
The data parser 202 is configured to provide a reading interface corresponding to each waveform data or data file one to one, and perform alignment processing on the waveform data and/or the data file according to a preset data alignment rule. The data file is data processed according to a predetermined format requirement and the like based on conventional waveform data in the system, for example, data formed by processing voltage waveform data acquired by the same device at the previous time, and data formed by processing current waveform data acquired by different devices at the previous time. That is, the source of the data file may be waveform data acquired by the same testing device at different time periods, or waveform data acquired by different devices at other time periods, and the waveform data has been converted into a file of a disk medium with description information. Each data source corresponds to one data parser 202, and one data source is waveform data corresponding to one real channel or one virtual channel, that is, waveform data acquired this time or a data file stored in a disk memory 206.
The arithmetic unit 203 is configured to obtain corresponding waveform data and/or data files from the data parser 202 according to an operation rule configured by a user, and perform an operation to obtain the calculated waveform data. The arithmetic unit 203 is a core for performing data operations in the system, and the arithmetic unit 203 in the embodiment is different from a conventional arithmetic unit in the conventional technology, and the conventional arithmetic unit is a direct read data storage device because a disk memory is not interfaced with the conventional arithmetic unit and a data file is not formed in the disk memory. However, in the embodiment, the arithmetic unit 103 does not directly read the memory, but indirectly obtains the data through the data parser 202, so as to realize the hybrid operation of the real channel data and the virtual file data.
The converter 204 of the embodiment is configured to process the calculated waveform data according to a preset processing rule to form a data file.

In the embodiment, the waveform data of a single channel is formed into an independent file, the file is analyzed in a file mode, the file can be independently used as a virtual channel, the dependence of operation on the channel is eliminated, and mixed data operation and multi-acquisition step-by-step operation of different products and equipment are realized.
FIG. 3 is a flowchart of an oscillometric method supporting an external data source according to an embodiment of the present application, where the oscillometric method supporting an external data source according to an embodiment of the present application may be performed by an oscillometric device supporting an external data source, and the oscillometric device supporting an external data source may be implemented in hardware and/or software and integrated in a computer device.
The following description will be given by taking as an example that an oscillographic device supporting an external data source performs an oscillographic method supporting the external data source. Referring to fig. 3, the oscillometric method supporting an external data source includes:
301: and receiving an operation rule input by a user.
In the above, the operation rule includes a formula character string, and the formula character string is used to represent corresponding waveform data or data file.
In the embodiment, the operation rule is configured by a user, and an operation interface for the user to configure is provided for the user in the oscilloscope. On the operation interface, the user can configure the input of parameters and the like involved in the whole process from the collection of the electric signals to the final output of the operation result. In an embodiment, the operation rule at least includes an operation formula, where the operation formula may be one or multiple according to actual needs, each operation formula includes a formula character string and an operation logic, the formula character string represents waveform data of different actual channels or data files of virtual channels, the operation logic is used to express a calculation logic between different formula character strings, for example, the operation rule configured by a user is C1+ V1, a character of C represents a corresponding actual channel, C1 represents waveform data collected corresponding to a first actual channel, V represents a corresponding virtual channel, V1 represents a data file corresponding to a first virtual channel, and "+" represents an operation logic, which represents that the waveform data collected by the first actual channel is added to the data file of the first virtual channel. The waveform data collected by the actual channel and the data file of the virtual channel are both used as data sources. Different formula strings are used to distinguish different data sources.
Preferably, after the user configures the operation rule, it may further determine whether to refer to external data, that is, whether to refer to a data file of the virtual channel. The data file of the virtual channel is also formed by converting waveform data acquired by the same equipment or different equipment into a specified format and is used as an external data source. Because different formula character strings are used for distinguishing different data sources, whether an external data source needs to be introduced or not can be detected according to the formula character strings in the operation rule configured by the user. When external data is judged to be quoted according to the formula character string, a mapping relation between the formula character string and the data file is established for the formula character string corresponding to the data file in the operation rule formula character string, namely the formula character string corresponding to the virtual channel in the operation rule is mapped to the corresponding data file, for example, V1 is mapped to the data file of the first virtual channel, and a mapping relation of each external data source is established.
302: and establishing a data analyzer respectively corresponding to each formula character string in the operation rule according to the operation rule.
In the embodiment, the data parser provides a reading interface corresponding to each waveform data or data file one to one, and aligns the waveform data and/or the data file according to a preset data alignment rule. For example, the operation rule configured by the user corresponds to an operation formula C1+ C2+ V2+ V3, then data resolvers corresponding to C1, C2, V2, and V3 are established, each data resolver provides a uniform external reading interface, the data resolver corresponding to C1 points to waveform data of a first actual channel, the data resolver corresponding to C2 points to waveform data of a second actual channel, the data resolver corresponding to V2 points to a data file corresponding to a second virtual channel, and the data resolver corresponding to V3 points to a data file corresponding to a third virtual channel.
303: and reading the waveform data or the data file corresponding to each formula character string according to the data parser, so that the formats of all the read waveform data and/or data files are aligned.
In this step, each data parser established in step 302 is actually analyzed, and waveform data or a data file is read from each data parser. Specifically, in this step, all data resolvers are traversed first, so that an alignment rule of information corresponding to all data resolvers is obtained, for example, C1 corresponds to waveform data with a sampling rate of 10kSa/s, and "V1" is a data file with a sampling rate of 50kSa/s, and in order to implement waveform superposition operation on a correct time axis, "V1" adopts a reading mode of processing 1 to 1, and "C1" adopts a reading mode of processing 5 to 1. It can be simply seen that each dot of "C1" will be copied into 5 identical dots, aligned in the same format as "V1". After the processing of the step, the data read by the data analyzer are aligned, and algorithm operation is performed on the basis.
304: and calculating the waveform data and/or the data file with the aligned formats according to the operation rule to obtain the calculated waveform data.
Preferably, the method may further include step 305, specifically, detecting whether format conversion is required for the calculated waveform data, and storing the waveform data after format conversion as a data file according to a preset processing rule when format conversion is required. In this step, it is detected whether a conversion instruction for performing format conversion on the calculated waveform data is received. The conversion instruction can be input together with the provided operation interface when the user configures the operation rule, or can be input actively by the user after the operation is finished. After the conversion instruction is provided, the calculated waveform data is converted and stored according to a preset processing rule, and at the moment, for example, specific data corresponding to different virtual channels are recorded, so that the subsequent application is facilitated. And the corresponding calculated waveform data is displayed through a display.

Preferably, a reference judging module 4011 is further included between the configuration receiving module 401 and the data parsing module 402, and configured to, when it is judged that external data is referred to according to the formula character string, establish a mapping relationship between the formula character string and the data file for a formula character string corresponding to the data file in the operation rule formula character string.
