Because the data volume transmitted each time in the mode is very small, the data acquisition of the oscilloscope is not required to be interrupted in the data transmission process; moreover, because the data acquisition frequency is high, and the data volume transmitted each time is small, a very high compression ratio or even a compression ratio is not required to be set for the data frequently, so that the problem of data loss caused by large-scale data compression is avoided. The embodiment of the invention also provides an oscilloscope.
Description
Technical Field
The invention relates to the technical field of oscillography, in particular to an oscilloscope and a method for reporting acquired data thereof.
Background
The ROLL mode of the oscilloscope is mainly used for measuring low-speed signals, such as power-on timing signal measurement of power supply output, monitoring of motor rotating speed and the like. It features that the frequency of the signal to be measured is low, and the oscilloscope works in low sampling rate (usually below 10M/s) mode. There is no dead time in this low sample rate mode, so every point acquired by the oscilloscope is displayed on the screen.
Fig. 1 is a block diagram of an internal structure of an existing oscilloscope, and as shown in fig. 1, after data is acquired by an FPGA data acquisition side, the data is reported to a CPU for subsequent processing. In the RUN state, the storage mode of the collected data is as follows: the acquired data is continuously written into an external memory, in the process, old data is continuously covered by new data, and one screen of data on the current screen is always stored in the memory.
However, in the above data storage manner, since the acquisition process cannot be stopped, the external memory is always occupied by the write operation, and the storage space inside the FPGA is limited and does not have a storage space for storing one screen of data. In this case, in order to report one screen of data to the CPU for data calculation, the following schemes are generally adopted:
1) the RUN state does not support the measurement function, and the user presses the STOP key to STOP data acquisition, and then reads data of one screen from the external memory for measurement;
2) and (3) compressing the data of one screen by adopting large-scale compression, storing the data into an FPGA internal memory, and reporting the data to software.
However, it is clear that the above solutions all have their own drawbacks. Firstly, data reporting is carried out after data acquisition is stopped, and the method cannot ensure the real-time performance of acquisition and is too complicated; secondly, for the way of reporting data after large-scale compression, because the data is compressed in a large scale, the detail information of the waveform is lost, which easily causes a large error of the measurement result, taking the case of a storage depth of 14M as an example, the storage resource inside the FPGA cannot store so much data, and the large-scale compression is necessary, if the frequency of the input signal is high, the number of points in each period is relatively small, so that a large error is brought when calculating the parameter related to the level.
However, in addition to the above solutions, if the storage space is directly enlarged enough, the cost of the oscilloscope is greatly increased, and the storage resource is wasted.

Detailed Description
The present invention will be described in further detail with reference to the following detailed description and accompanying drawings.
Example one
Referring to fig. 2, a flowchart illustrating steps of a method for reporting measurement data in an oscilloscope according to the present invention is shown, where the method specifically includes:
in the specific implementation, a small Random Access Memory (RAM) is arranged on a data acquisition side of a Field-Programmable Gate Array (FPGA), and the RAM is used for data acquired by the FPGA data acquisition side.
in the step, the FPGA data acquisition side can actively report the data to the CPU; or the CPU actively acquires data from the RAM; the concrete implementation is as follows:
a. the scheme for actively reporting data to the CPU specifically comprises the following steps:
the FPGA data acquisition side inquires a write address and a read address of the RAM according to a first preset time interval, determines the difference COUNT between the write address and the read address, determines the data volume currently stored in the RAM according to the determined COUNT, and sends the data in the RAM to the CPU when the data volume currently stored in the RAM is larger than a preset threshold value.
b. The scheme for the CPU to actively acquire data from the RAM specifically comprises the following steps:
the CPU inquires the writing address and the reading address in the RAM according to a second preset time interval, determines the difference COUNT between the writing address and the reading address in the RAM, determines the data volume currently stored in the RAM according to the determined COUNT, and reads the data in the RAM when the data volume currently stored in the RAM is larger than a preset threshold value; specifically, the CPU can read data in the RAM through the read port.
Specifically, the data in the RAM is output according to a first-in first-out principle.
In practical application, values of the first preset time interval and the second preset time interval can be set and adjusted according to actual needs, and the values of the first preset time interval and the second preset time interval can be the same or different; the value of the COUNT can also be set and adjusted as required.
For example, if one screen of data includes 100 point data, COUNT can be set as the storage amount of 10 point data according to time requirement, and the data obtained from the RAM is sent to the CPU after being filled with 10 point data, and the CPU combines the data obtained from the RAM to obtain one screen of data.
During specific implementation, the CPU determines the head data and the tail data of one screen of data from the obtained data, namely the head data, the tail data and the data between the head data and the tail data can jointly form one screen of data, so that the one screen of data is analyzed, and a corresponding analysis result is obtained.
In an optional implementation manner of the present invention, before sending the data in the RAM to the CPU, the method further includes:
when the following conditions are met, configuring a compression ratio to the RAM, and compressing data in the RAM according to the configured compression ratio:
S×T>D；
wherein, S is the sampling rate of the current time base of the oscilloscope in the ROLL mode, and specifically comprises: extracting the number of sampling points forming a discrete signal from the continuous signal every second; t is CPU access interval, and the unit is second; d is the size of the RAM storage space.
Specifically, the compression ratio C allocated to the RAM needs to satisfy the following condition:
S×T÷C<D；
wherein S is the sampling rate of the current time base of the oscilloscope in the ROLL mode; t is CPU access interval, and the unit is second; d is the size of the RAM storage space.
Only when the compression ratio C meets the above condition, the data in the RAM is compressed according to the set compression ratio, so that the data can not be lost.
For example, when the storage depth of the oscilloscope is set to 1.4M, assuming that the sampling rate S of the 50ms time base in the ROLL mode is 2M, RAM storage space D is 10000 and the CPU access interval T is 0.05(50ms), the compression ratio C needs to be set above 10 to ensure that data is not lost. When the sampling rate S of the 500ms time base in the ROLL mode is 200K, RAM, the storage space D is 10000, and the CPU access interval T is 0.05, the compression ratio C is set to 1, so that the data is guaranteed not to be lost; in both of the above examples, C is set to 1 after the time base is adjusted to a value greater than 500 ms.
To sum up, the method for reporting measurement data in an oscilloscope according to the embodiments of the present invention writes acquired data into an RAM during data acquisition, and then, a CPU acquires data from the RAM and combines the data acquired from the RAM to generate one screen of data. Firstly, the data volume transmitted in each time in the mode is very small, and the data acquisition of the oscilloscope is not required to be interrupted in the data transmission process; moreover, because the frequency of data acquisition is higher, and the data volume transmitted each time is very small, the data does not need to be set with a very high compression ratio or even set with a compression ratio frequently, and the problem of data loss caused by large-proportion data compression is avoided; in addition, according to the scheme, a very large storage space does not need to be arranged in the oscilloscope, so that the cost of the oscilloscope is reduced, and the storage resource is saved.
