All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
The method for capturing any data provided in the embodiment of the application is applied to an embedded system. The embedded system comprises a first chip, a second chip and a timer, wherein as shown in fig. 1, the timer can complete a high-precision timing function, the timer can simultaneously send signals to the first chip and the second chip, and the first chip can transmit data to the second chip. The first chip is a processing center which can independently realize the functions of data acquisition, processing, transmission and the like; meanwhile, the second chip is a processing center which can independently realize the functions of data acquisition, processing, transmission and the like. The first chip and the second chip are two independent processing centers, for example, the first chip is a first Micro Controller Unit (MCU), the second chip is a second MCU, and the protection scope of the present application is not limited by the implementation form of the first chip and the second chip.
In one embodiment, with the second chip as the execution subject, as shown in fig. 2, the specific steps of the method for capturing arbitrary data are as follows:
In this embodiment, the data sequence of the object to be measured is a series of data to be captured arranged in time sequence. The data sequence of the measured object comprises at least one type of data. The second chip obtains the first sample measured object data and the second sample measured object data in the measured object data sequence. The first sample measured data and the second sample measured data correspond to different moments in the measured object data sequence.
In step 202, the second chip obtains first sample reference data, second sample reference data and target reference data transmitted by the first chip, wherein the first sample reference data, the second sample reference data and the target reference data belong to a reference data sequence.
In this embodiment, the reference data sequence is arranged in time series in advance, and a series of data of an arbitrary bit of data can be captured by the first chip. Preferably, the reference data sequence contains only one type of data. The reference data sequence is preset according to actual conditions and/or needs, and the application is not limited by the setting principle and specific setting content of the reference data sequence.
The first chip acquires first sample reference data, second sample reference data, and target reference data in a reference data sequence. The first sample reference data and the second sample reference data correspond to different time instants of the reference data sequence, respectively. The target reference data is the reference data captured by the first chip at the moment when the data of the measured object needs to be captured. After the first chip acquires the first sample reference data, the second sample reference data and the target data, the first chip transmits the first sample reference data, the second sample reference data and the target data to the second chip.
In this embodiment, each measured object data in the measured object data sequence corresponds to each reference data in the reference data sequence one by one according to the sequence order; the first sample measurand data corresponds to the first sample reference data, and the second sample measurand data corresponds to the second sample reference data. That is, the first sample measured object data and the first sample reference data are data captured in the measured object data sequence and the reference data sequence by the second chip and the first chip respectively at the same time; the second sample measured object data and the second sample reference data are data captured in the measured object data sequence and the reference data sequence respectively by the second chip and the first chip at the same time. The first sample reference data and the second sample reference data are different at the time of capture.
And step 203, the second chip calculates and obtains target measured object data corresponding to the target reference data according to the data corresponding relation between the measured object data sequence and the reference data sequence according to the first sample measured object data, the second sample measured object data, the target reference data, the first sample reference data and the second sample reference data.
In this embodiment, since the data sequence of the object to be measured and the reference data sequence have an object relationship, when the first chip transmits the first sample reference data, the second sample reference data and the target reference data to the second chip, the second chip can calculate and obtain the target object to be measured corresponding to the target reference data according to the data correspondence between the data sequence of the object to be measured and the reference data sequence, based on the first sample object to be measured, the second sample object to be measured, the target reference data, the first sample reference data and the second sample reference data. Because the first chip can capture the reference data at any time as the target reference data, the process of capturing the data of the tested object at any time is equivalently realized, the data capturing precision is ensured, the data capturing diversity is improved, and the data capturing efficiency of the embedded system is improved.
In one embodiment, the first chip and the second chip respectively provide the trigger signal by a timer when acquiring data in the reference data sequence and the data sequence of the object to be tested. The second chip obtains a first sample measured object data and a second sample measured object data in the measured object data sequence, and the specific process is as follows: when receiving a first time trigger signal transmitted by a timer, the second chip captures first sample measured object data in a measured object data sequence; and when receiving a second time trigger signal transmitted by the timer, the second chip captures second sample measured object data in the measured object data sequence.
For the reference data sequence, the target reference data is the reference data captured in the reference data sequence when the first chip receives a data capture trigger signal transmitted from the outside; the first sample reference data is reference data captured in a reference data sequence when the first chip receives a first time trigger signal; the second sample reference data is reference data captured in the reference data sequence when the first chip receives the second time trigger signal.
In this embodiment, the first sample data to be measured and the first sample reference data are captured when the first time trigger signal is received, so that it is ensured that the first sample data to be measured captured by the second chip in the data sequence to be measured corresponds to the first sample reference data captured by the first chip in the reference data sequence.
The second sample measured object data and the second sample reference data are captured when the trigger signal at the second moment is received, so that the second sample measured object data captured by the second chip in the measured object data sequence is ensured to correspond to the second sample reference data captured by the first chip in the reference data sequence.
In this embodiment, when any data in the data sequence of the object to be tested needs to be captured, the external device transmits a data capture trigger signal to the first chip. After receiving the data capture trigger signal, the first chip captures target reference data in a reference data sequence. And then the second chip calculates to obtain target measured object data corresponding to the target reference data.
In one embodiment, the first time trigger signal and the second time trigger signal are respectively time trigger signals generated by a timer in adjacent periods, wherein the time trigger signals are generated by the timer with a preset time length as a period; a first time trigger signal is sent to the first chip and the second chip through the timer at the same time; and the second moment trigger signal is simultaneously sent to the first chip and the second chip through the timer.
In this embodiment, the timer generates the time trigger signal with a preset time length as a period, and the first time trigger signal and the second time trigger signal are time trigger signals generated in adjacent periods. After the timer generates the first time trigger signal, the timer simultaneously sends the first time trigger signal to the first chip and the second chip to ensure that the first chip and the second chip can simultaneously receive the first time trigger signal, or ensure that the first chip and the second chip receive the first time trigger signal within an allowable time error range, so that the first sample reference data captured by the first chip corresponds to the first sample measured object data captured by the second chip.
Correspondingly, after the timer generates the second time trigger signal, the timer simultaneously sends the second time trigger signal to the first chip and the second chip to ensure that the first chip and the second chip can simultaneously receive the second time trigger signal, or ensure that the first chip and the second chip receive the second time trigger signal within the allowable time error range, so that the second sample reference data captured by the first chip corresponds to the second sample measured object data captured by the second chip.
In this embodiment, the timer is used as the preset duration of the period, and is set according to actual conditions and/or needs, and the protection scope of the present application is not limited by the setting principle and the setting content of the preset duration.
In a specific embodiment, the target reference data is arranged in the reference data sequence intermediate the first sample reference data and the second sample reference data. That is, after the first chip captures target reference data according to the externally transmitted data capture trigger signal, the first chip uses the previously captured sample reference data as the first sample reference data when capturing the target reference data, and transmits the next captured sample reference data as the second sample reference data when capturing the target reference data to the second chip.
And transmitting the two sample reference data closest to the target reference data capturing moment to the second chip so as to calculate and obtain the finally required target measured object data, thereby avoiding the error caused by the fact that the sample data is too large from the target data and further improving the data capturing precision.
In one embodiment, the second chip calculates and obtains target measured object data corresponding to the target reference data according to the data correspondence between the measured object data sequence and the reference data sequence, based on the first sample measured object data, the second sample measured object data, the target reference data, the first sample reference data, and the second sample reference data, and the specific process is as follows:
acquiring a preset data calculation formula according to the data corresponding relation between the data sequence of the object to be measured and the reference data sequence, wherein the data calculation formula is as follows:
and calculating to obtain target measured object data corresponding to the target reference data according to a data calculation formula.
In this embodiment, each bit of measured object data in the measured object data sequence corresponds to each bit of reference data in the reference data sequence one by one according to the sequence order, and the target measured object data corresponding to the target reference data is linearly calculated by the data calculation formula. The data calculation formula has simple logic, is beneficial to improving the calculation speed of the second chip, and further improves the overall efficiency of data capture.
In a specific embodiment, as shown in fig. 3, two straight lines respectively represent the measured object data sequence and the reference data sequence, b (i) is the first sample reference data, b (i + 1) is the second sample reference data, p (i) is the first sample measured object data, p (i + 1) is the second sample measured object data, b (T) is the target reference data captured by the first chip at time T, p (T) is the target measured object data, and T is a preset duration with a timer as a period, where i is an integer greater than or equal to 1.
The timer transmits a first time trigger signal to the first chip and the second chip at the same time at the time t1, the first chip captures first sample reference data b (i) in a reference data sequence, and the second chip captures first sample measured object data p (i) in a measured object data sequence. And the timer simultaneously transmits a second time trigger signal to the first chip and the second chip at the time t2, the first chip captures second sample reference data b (i + 1) in the reference data sequence, and the second chip captures second sample measured object data p (i + 1) in the measured object data sequence. When the first chip receives a data capture trigger signal transmitted from the outside at time t, the target reference data b (t) is captured in the reference data sequence.
Applying the data calculation formula in the above embodiment can obtain the following formula:
converting the formula to obtain a calculation formula of the target measured object data p (t), wherein the calculation formula comprises the following steps:
in this embodiment, the first chip may receive a data capture trigger signal transmitted from outside at any time to capture any data in the reference data sequence. Through the above process, the present embodiment can calculate and obtain the target measured object data corresponding to the target reference data, that is, capture of any data in the measured object data sequence is achieved.
According to the method for capturing any data, the second chip obtains first sample measured object data and second sample measured object data in a measured object data sequence, and then the second chip obtains first sample reference data, second sample reference data and target reference data in a reference data sequence transmitted by the first chip. Each measured object data in the measured object data sequence corresponds to each reference data in the reference data sequence one by one according to the sequence data. The first sample measured object data and the first sample reference data are corresponding, and the second sample measured object data and the second sample reference data are corresponding. Through the corresponding relation between the measured object data sequence and the reference data sequence, the second chip can calculate the target measured object data corresponding to the target reference data through the obtained data, namely the capture of the measured object data is completed.
According to the method, the target reference data is determined in the reference data sequence, and the target measured object data corresponding to the target reference data can be determined according to the corresponding relation between the measured object data sequence and the reference data sequence. In the process, the type of the measured object data does not need to be determined, any one piece of reference data is captured in the reference data sequence to serve as the target reference data, and the target measured object data corresponding to the target reference data in the measured object data sequence can be determined, namely, the process of capturing any one piece of measured object data in the measured object data sequence is realized.
For the method of capturing fixed data, when the main frequency of the processing chip is 100Mhz (Mhz for short), the error of the method in capturing data is within 10 nanoseconds (ns for short). According to the method for capturing the arbitrary data, when the arbitrary data in the data sequence of the object to be measured is captured through the reference data sequence, and when the main frequencies of the first chip and the second chip are both 100Mhz, the method for capturing the arbitrary data can also ensure that the error in data capturing is within 10 ns. That is, the method for capturing arbitrary data provided by the present application can ensure the same accuracy as the method for capturing fixed data. The method provided by the application does not sacrifice the accuracy of data capture.
Compared with the method for capturing fixed data, the method for capturing the arbitrary data is more flexible in capture mode, specific types of the data of the tested object do not need to be detected, the data capture precision is guaranteed, meanwhile, the diversity of data capture is improved, more resources are not wasted by an embedded system, and the efficiency of capturing the data by the embedded system is improved.
