Based on the above embodiments, the present embodiment further describes and optimizes the technical solution, please refer to fig. 4, and fig. 4 is a structural diagram of another data acquisition device provided by the embodiment of the present invention. Specifically, the filter circuit module 11 includes:

and the RTD filter circuit 114 is used for acquiring RTD data in the target DCS and preprocessing the RTD data to obtain RTD filter data.
In this embodiment, a DI filter circuit 111, an AI filter circuit 112, a TC filter circuit 113, and a RTD filter circuit 114 are provided in the filter circuit module 11, DI data, AI data, TC data, and RTD data in the target DCS are obtained by respectively using the DI filter circuit 111, the AI filter circuit 112, the TC filter circuit 113, and the RTD filter circuit 114, and after the DI filter circuit 111, the AI filter circuit 112, the TC filter circuit 113, and the RTD filter circuit 114 obtain the DI data, the AI data, the TC data, and the RTD data in the target DCS, the DI data, the AI data, the TC data, and the RTD data are respectively preprocessed, so as to obtain the DI filter data, the AI filter data, the TC filter data, and the RTD filter data.
It can be understood that, in practical applications, the DI data, the AI data, the TC data, and the RTD data are data types with higher frequency in the target DCS, so when the filter circuit module 11 is configured in such a manner, the universality of the data acquisition apparatus in practical applications can be further improved.
In a preferred embodiment, the parallel processor 12 is embodied as a target chip 120 provided with FPGA + MCU.
Specifically, in the present embodiment, the parallel processor 12 is configured as the target chip 120 having an FPGA (Field Programmable Gate Array, Field Programmable logic Gate circuit) + MCU (Microcontroller Unit), because the FPGA is integrated with hardware resources such as a logic Unit, a multiplier, a RAM (Random Access Memory), and the like, and the MCU is a highly integrated processor with a general structure, when the parallel processor 12 is configured as the target chip 120 having the FPGA and the MCU, the data processing performance of the parallel processor 12 can be further improved, and thus the data acquisition apparatus can have a faster data acquisition capability.
As a preferred embodiment, the target chip 120 includes:
a DI logic module 121 for extracting first useful data in the DI filtered data;
an AI logic module 122 for extracting second useful data in the AI filtered data;
a TC logic module 123 for extracting third useful data in the TC filtered data;
and RTD logic module 124 for extracting fourth useful data from the RTD filtered data.
In order to further improve the data processing capability of the target chip 120, in the present embodiment, the DI logic module 121, the AI logic module 122, the TC logic module 123 and the RTD logic module 124 are respectively disposed in the target chip 120, and the DI logic module 121, the AI logic module 122, the TC logic module 123 and the RTD logic module 124 are utilized to respectively extract useful data in the DI filter data, the AI filter data, the TC filter data and the RTD filter data. This corresponds to removing the noise signals from the DI filter data, the AI filter data, the TC filter data, and the RTD filter data using a software algorithm, and further filtering and de-noising the DI filter data, the AI filter data, the TC filter data, and the RTD filter data.
Obviously, by such a processing mode, not only can the extraction results of the first useful data, the second useful data, the third useful data and the fourth useful data be avoided to be more accurate and reliable, but also the mutual interference and influence of the first useful data, the second useful data, the third useful data and the fourth useful data in the extraction process can be avoided.
As a preferred embodiment, the target chip 120 includes:
and a data area 125 for performing format conversion on the first useful data, the second useful data, the third useful data and the fourth useful data respectively by using a first communication protocol corresponding to the first useful data, a second communication protocol corresponding to the second useful data, a third communication protocol corresponding to the third useful data and a fourth communication protocol corresponding to the fourth useful data, so as to obtain first conversion data, second conversion data, third conversion data and fourth conversion data respectively.
In this embodiment, in order to further increase the acquisition speed of the data acquisition device in the data acquisition process of the target DCS, a data area 125 is further disposed in the target chip 120, and the data area 125 is used to perform corresponding data conversion on the first useful data, the second useful data, the third useful data and the fourth useful data.
That is, the first useful data, the second useful data, the third useful data and the fourth useful data are subjected to format conversion by using a first communication protocol corresponding to the first useful data, a second communication protocol corresponding to the second useful data, a third communication protocol corresponding to the third useful data and a fourth communication protocol corresponding to the fourth useful data, respectively, so as to obtain corresponding conversion data.
It is conceivable that, when the first, second, third, and fourth useful data are converted into corresponding conversion data using the first, second, third, and fourth communication protocols, respectively, DI, AI, TC, and RTD data in the target DCS are converted into data directly used in actual applications according to the international general standard. Obviously, by means of such an operation means, not only the complicated operation steps of the upper computer 13 in the subsequent process are removed, but also the data extraction process of the upper computer 13 is more convenient and efficient.
Referring to fig. 5, fig. 5 is a block diagram of another data acquisition device according to an embodiment of the present invention. As a preferred embodiment, the data acquisition apparatus further includes:
the ADC chip 14 is connected to the target chip 120, and configured to convert the TC filtered data and/or the RTD filtered data into a first data signal and/or a second data signal, and transmit the first data signal and/or the second data signal to the TC logic module 123 and/or the RTD logic module 124.
It is understood that the TC filtered data is obtained by converting thermocouple data in the target DCS, and the RTD filtered data is obtained by converting thermal resistance data in the target DCS, and this format of data is not a data format that the target chip 120 can directly process.
Therefore, in this embodiment, in order to further increase the data processing speed of the target chip 120 on the TC filtered data and/or the RTD filtered data, the ADC chip 14 is further connected to the target chip 120, and the ADC chip 14 is used to convert the TC filtered data and/or the RTD filtered data into the first digital signal and/or the second digital signal that can be directly processed by the target chip 120, so as to further increase the data processing speed of the TC logic module 123 and/or the RTD logic module 124.
As a preferred embodiment, the ADC chip 14 includes:
and an SPI interface for connecting with the target chip 120.
Specifically, in the present embodiment, the TC filter circuit 113 and/or the RTD filter circuit 114 are/is communicatively connected to the target chip 120 through the SPI interface in the ADC chip 14, because the SPI interface not only has a high data transmission rate, but also supports full-duplex operation, so that when the ADC chip 14 is communicatively connected to the target chip 120 through the SPI interface, the communication rate between the ADC chip 14 and the target chip 120 can be relatively increased. In practical applications, the ADC chip 14 may be further optimized to make the ADC have stronger electromagnetic interference capability.
Based on the above embodiment, this embodiment further describes and optimizes the technical solution, and the upper computer 13 further includes:
and the display is used for displaying the target conversion data.
In this embodiment, a display is also provided on the upper computer 13, and the target conversion data is displayed by the display. It can be thought that, when the target conversion data is displayed through the display, not only can the user more clearly and intuitively check the target conversion data, but also the user can use the target conversion data in the subsequent process more conveniently, so that the user experience of the user in the process of using the data acquisition device is further improved.
