基于FPGA的多通道数据采集存储装置
Multi-channel data acquisition and storage device based on FPGA
摘要
Abstract
The parameter performance of each load on the probe in the process of space exploration has great significance to the perform-ance evaluation and structural optimization of the probe.In order to solve this problem,this paper designs a multi-channel,high-speed data acquisition and storage device with field programmable gate array(FPGA)as the core by using a high-performance A/D conversion chip to realize real-time acquisition,conversion,framing and data storage of 16 analog signals,as well as the reception of LVDS transmis-sion data.Then it is transmitted to the system process control unit in real time through the GPIO bus,and can also be stored in Flash memory to realize communication and external telemetry with the host computer through Gigabit Ethernet.The experiment results show that after data comparison,the collected data is consistent with the data source,there is no frame loss and no error code,and the data ac-quisition and storage meet the technical requirements and realize the expected function.关键词
