Multi-network fused FPGA (Field Programmable Gate Array) data acquisition server

Abstract

The invention discloses a multi-network fused FPGA (Field Programmable Gate Array) data acquisition server. The multi-network fused FPGA data acquisition server comprises a core control module, a WIFI (Wireless Fidelity) wireless communication module, a 3G (The 3rd Generation Telecommunication) wireless communication module, a Zigbee wireless communication module and a common function module. According to the multi-network fused FPGA data acquisition server, an FPGA is used as a hardware platform and an embedded Linux technology and an embedded WEB technology are adopted so as to realize conversion and seamless connection of network protocol data of a zigbee protocol, 3G, Wifi, RJ45 and the like.

Description

technical field [0001] The invention belongs to the technical field of serial port servers, and relates to a multi-network fusion FPGA data acquisition server. Background technique [0002] The existing serial server can realize the conversion of interface data such as RS232 / 422 / 485 into Wifi or RJ45, so as to realize the conversion of serial data into network data and access to the Internet network. However, the serial port server is expensive and requires network charges, so it is not suitable for use in a large area at the front end; the existing Zigbee network module can realize the wireless transmission of existing sensor data, which has a low price and does not require network charges. Advantage. However, due to the inability to directly access the Internet network, the advantages of the system in remote monitoring are relatively weak; in terms of data transmission rate, ARM-based microcontroller data acquisition systems based on serial data are different from those b...

AI Technical Summary

Problems solved by technology

[0003] In order to overcome the defects in the existing technology, solve the problem that the zigbee network module cannot be connected to the Internet network, so that the data acquisition system cannot realize remote monitoring; 3G, WIFI and other modules are expensive and require network fees, resulting in the multi-point data acquisition system The problem of high investment costs
