Miniaturized synchronous time service and data transmission device based on FPGA and application thereof

Abstract

The invention discloses a miniaturized synchronous time service and data transmission device based on a FPGA. The miniaturized synchronous time service and data transmission device based on the FPGA comprises a serial deserializer, a FPGA, a synchronous time service interface, and a data transceiver interface; the serial deserializer is used for deserializing data on the data\clock multiplexing bus to obtain the synchronous clock and transmission data, and transmitting the synchronous clock and transmission data to the FPGA; the FPGA is used for forwarding the received synchronous clock and transmission data to a plurality of slave devices, controlling synchronous sampling of the plurality of slave devices, encapsulating the transmission data uploaded by the plurality of slave devices andtransmitting to the serial deserializer; the synchronous time service interface is used for realizing the transmission of the synchronous clock between the FPGA and the plurality of slave devices; andthe data transceiver interface is used for realizing the transmission of the transmission data between the FPGA and the plurality of slave devices. The miniaturized synchronous time service and datatransmission device based on the FPGA reduces the size and complexity of the whole system engineering, and improves the system performance under the circumstance of long distance transmission.

Description

technical field [0001] The invention relates to the field of FPGA technology and data synchronization and transmission technology, in particular to an FPGA-based miniaturized device for synchronous timing and data transmission and its application. Background technique [0002] The collection, transmission and processing of field data has become an indispensable link in industrial control, production and scientific research. The data acquisition system mainly completes the acquisition, A / D conversion and processing of data information, and then sends it to the computer for further processing and storage or feeds back the processing results to the equipment for related control. [0003] The data acquisition system is an important part of the Internet of Things, which can provide real-time data for management and control, and provide an important basis for operators to monitor and analyze equipment. In order to shorten the system development cycle and avoid repeated system des...
