Problems solved by technology

In many cases, scientific analysis needs raw data based on multiple sensors, so the data processing system must realize remote real-time interaction of large-capacity raw information. will be greatly improved, otherwise it will not be possible to comprehensively analyze and process the physical characteristic signals of the same detection target obtained by different sensors
[0003] The industrial computer with embedded architecture is widely used in many occasions sensitive to space, power and weight due to its small size and many specifications, but it is its small size and many specifications that make it possible to directly connect to industrial control There are relatively few industrial real-time bus boards for the internal bus of the computer, which makes it difficult to connect the industrial computer with embedded architecture with various real-time industrial buses. It is necessary to formulate technical solutions according to specific situations, and the compatibility of different specific situations is poor.

Embodiment 1

[0043] Such as figure 1 and figure 2 As shown, the present embodiment provides a data processing device 100, which is used in a measuring device 300, and the measuring device 300 sequentially enters the detection target, and the data processing device 100 includes: a plurality of sensors 110, a first field programmable logic gate array 120, industrial computer 130, microprocessor 140 and real-time field bus 150; Sensor 110 is located on measuring equipment 300, as image 3 As shown, the sensor 110 includes a physical detector 112, an analog-to-digital conversion circuit 114 and a second field programmable logic gate array 116, and the second field programmable logic gate array 116 receives the detection target output by the first field programmable logic gate array 120 Object position signal and signal acquisition frequency, control physical detector 112 to detect detection object according to detection object position signal and signal acquisition frequency, physical detect...

Embodiment 2

[0050] In addition to the technical features of the above-mentioned embodiments, this embodiment further includes the following technical features:

[0051] The first field programmable logic gate array 120 and the second field programmable logic gate array 116 communicate through a synchronous serial bus, using a high-speed differential protocol, and the second field programmable logic gate array 116 converts periodic data into serial The row data format is output to the first field programmable logic gate array 120.

[0052] In this embodiment, the first FPGA 120 and the second FPGA 116 communicate through a synchronous serial interface, making the communication easier, more convenient, and more flexible. The communication protocol adopts a high-speed differential protocol, High-speed differential has the advantages of strong anti-interference ability, effective suppression and precise timing positioning.

Embodiment 3

[0054] In addition to the technical features of the above-mentioned embodiments, this embodiment further includes the following technical features:

[0055] Synchronous serial buses include serial peripheral interface buses.

[0056] In this embodiment, the synchronous serial interface can adopt SPI (Serial Peripheral Interface, Serial Peripheral Interface) bus, the SPI bus communication principle is simple, easy to operate, and, SPI bus is a kind of three-wire synchronous bus, because its hardware function is very Strong, so the software related to SPI is relatively simple, so that the CPU has more time to deal with other affairs.

Abstract

The invention provides a data processing device and method. The data processing device comprises a plurality of sensors, a first field programmable logic gate array, an industrial personal computer, a microprocessor and a real-time field bus. A plurality of sensors are distributed at different positions of measurement equipment; And original data of the sensors which are physically distributed independently are uploaded to the industrial personal computer outside a certain physical distance for calculation through the first field programmable logic gate array and a second field programmable logic gate array, so that the data of each sensor can be comprehensively analyzed, and the real-time requirement is met. The industrial personal computer carries out non-real-time data and instruction interaction with the outside, real-time data instructions and non-real-time data instructions are processed separately, and the requirements for functionality and data integrity can be met under the condition that the real-time requirement is met.

Description

technical field [0001] The present invention relates to the technical field of data processing, and in particular, to a data processing device and method. Background technique [0002] In the equipment that adopts multi-sensor detection for the same detection target, it is very necessary to conduct real-time comprehensive analysis of the information of multiple sensors for the physically independently distributed sensors. In many cases, scientific analysis needs raw data based on multiple sensors, so the data processing system must realize remote real-time interaction of large-capacity raw information. Otherwise, it is impossible to comprehensively analyze and process the physical characteristic signals obtained by different sensors of the same detection target. [0003] The industrial computer with embedded architecture is widely used in many occasions sensitive to space, power and weight due to its small size and many specifications, but it is its small size and many spec...
