强电磁场环境下数据采集实现方法研究

Data acquisition implementation method under strong electromagnetic field

在强电磁场环境下,传统的数据采集系统难以精确地进行有效可靠的数据采集,针对这种状况,采取了多种电磁屏蔽办法,包括设计电磁屏蔽体屏蔽采集系统前端干扰、构建光纤以太网络保障传输数据的纯洁性等,另外,数据采集系统设计以FPGA为主控芯片,采用DSP进行数据压缩传输,结果表明,整个采集系统更加稳定可靠,抗干扰能力得到了大幅度提升,而且数据采集的精度和传输速度也得到了提升,有效解决了复杂电磁场环境下的数据采集与传输。

In strong electromagnetic field environment,it is difficult for the traditional data acquisition system to carry out effective and reliable data acquisition accurately.To deal this situation,a variety of electromagnetic shielding options have been taken,including designing electromagnetic shield to shield the front-end interference of the acquisition system,building fiber-optic Ethernet to ensure the purity of transmission data,etc.In addition,taking FPGA as the main chip of data acquisition systems and using DSP for data compression and transmission.The results show that the whole system is more stable and reliable,and the anti-interference ability has been greatly improved,and the precision and transmission speed of the data acquisition have also been improved,which act as effective solution to the data collection and transferring under complex electromagnetic environment.
