Problems solved by technology

Using the traditional X86 processor platform to carry out the design of the acquisition device will greatly increase the design complexity. At the same time, in these scenarios, there are strict requirements on power consumption, volume and bandwidth. Therefore, the data acquisition system must be designed and implemented using an embedded platform. To meet the characteristics of miniaturization, low power consumption, high real-time performance, high bandwidth, etc.

Abstract

The invention relates to the technical field of data acquisition, particular to a real-time collecting device of multi-source data. The invention puts forward a real-time multi-source data acquisitiondevice design method based on an FPGA. A main processor is used for operating a VxWorks real-time operating system so as to realize multi-source data scheduling and file storage management; and convenient file outputting is realized based on an FTP network protocol and a USB interface. Meanwhile, management of different types of data sources is realized by using a soft core of a slave processor,so that a data source channel is increased or deleted flexibly and a real-time data acquisition system that satisfies different application scene demands is constructed quickly. The real-time collecting device has characteristics of modularization, good real-time performance, low power consumption, and high flexibility and scalability and the like.

Description

technical field [0001] The invention relates to the technical field of data acquisition, in particular to a multi-source data real-time acquisition device. Background technique [0002] For application scenarios such as video acquisition, radar data recording, and vehicle bus monitoring, it is necessary to collect and store process data such as video streams, raw radar signals, voice data, and bus interactions in real time, and to playback, export, and analyze data at specific times . Using the traditional X86 processor platform to carry out the design of the acquisition device will greatly increase the design complexity. At the same time, in these scenarios, there are strict requirements on power consumption, volume and bandwidth. Therefore, the data acquisition system must be designed and implemented using an embedded platform. To meet the characteristics of miniaturization, low power consumption, high real-time performance, and high bandwidth. Contents of the invention...
