Data storage and export system and method thereof

Abstract

The invention relates to the field of digital electronic control, and particularly discloses a data storage and export system, which comprises a power supply circuit, a processor circuit, an FPGA circuit, a memory circuit, a network chip and an interface circuit, and is characterized in that the processor circuit, the memory circuit, the network chip and the interface circuit are all connected with the FPGA circuit; in the data storage stage, the data is generated or processed by the processor circuit and is stored in the memory circuit through the FPGA circuit; and in the data exporting stage, the data is read from the memory circuit and exported to an external computer through the FPGA circuit, the network chip and the interface circuit. The invention also discloses a method for storing and exporting data by using the system. The data storage and export system provided by the invention can be applied to various controllers with data access requirements, and storage and rapid export of a large amount of data can be realized only by adding a small amount of additional devices.

Description

technical field [0001] The present invention relates to the field of digital electronic control, more specifically, to a data storage and export system and method thereof. Background technique [0002] With the continuous development of automation technology, various controllers are born. With the increase of control variables and the extension of control time, the demand for storage and export of large data volumes gradually appears; the general data storage and export scheme of existing controllers There are several types as follows: 1. The storage and export functions are all realized by the processor circuit, through serial bus communication, common ones are RS422, CAN bus, USB bus, etc.; the processor communicates with the external computer, and then reads the data in the memory , and then exported to an external computer via a serial bus. 2. The storage function is realized by the processor circuit, the export function is connected to the Ethernet chip through the FPG...
