ARM-based data acquisition network uploading device and method

Abstract

The invention relates to the communication technical field, in particular to an ARM-based data acquisition network uploading device with high efficiency and low cost. The device is characterized by comprising an FPGA (Field Programmable Gate Array) module used for carrying out data acquisition and processing, an ARM module used for receiving data output by the FPGA module and packaging and uploading according to a UDP (User Datagram Protocol), a PHY (Physical Layer) module used for receiving the data uploaded by the ARM module and an RJ45 interface module connected to the PHY module. The FPGA module adopts ALTERA Cyclone V series, the ARM module adopts ATMEL SAMA5 series, the PHY module adopts Micrel ksz9031 series, and the RJ45 interface can upload the data to an upper computer or a router. In comparison with the prior art, gigabit Ethernet is realized based on the ARM, and meanwhile, the device and the method have the advantages of low cost, safety, reliability and the like and are suitable for data acquisition and uploading application of mass data in multiple fields.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to an ARM-based data acquisition network upload device and method with high efficiency and low cost. Background technique [0002] Most of the current data acquisition network upload devices only use FPGA with Gigabit MAC through external PHY chips. However, the gigabit network implemented by FPGA has the disadvantages of high resource consumption, high development difficulty, high development cost, and long cycle. Moreover, FPGA needs soft-core support to realize gigabit network, but the price of soft-core is relatively expensive, which limits its development. [0003] With the rapid development of ARM, more and more chips themselves support or embed Gigabit MAC, and the chip price is also constantly falling. The device implemented based on ARM can solve the above shortcomings very well. FPGA only implements fast data collection and transmission, and ARM implements data p...
