摘　　要：嵌入式控制系统需要通过电子测量方式进行数据采集,为控制系统提供输入参量模型,采用VXI总线技术进行嵌入式控制系统的32通道控制数据采集和实时数据记录,方便控制系统和客户端现场分析数据。嵌入式控制系统的VXI总线数据采集软件是建立在对控制信息的特征采样和控制参量的信息输入基础上,进行VXI总线数据采集系统总体设计描述和功能指标分析,数据采集通过发射天线、接收天线、发射机、接收机、控制器等构件实现。数据采集系统的软件模块设计包括了通道设置、触发设置、数据端口设置、数据可视化模块设计和数据读取回放等子模块,通过软件优化设计实现VXI总线数据采集。实验分析结果表明,该系统进行数据采集的输入和输出的波形控制的匹配性能较高,稳定性较好,具有较高的数据采集精度。Embedded control system need by electronic measurement of data acquisition, providing the input parameters of the model for the control system, based on VXI bus technology for embedded control system of 32 channel control data acquisition and real-time data recording, convenient control system and client site data analysis. The embedded control system of VXI bus data acquisition system is established in the characteristics of sampling and control parameters of information input based on VXI bus data acquisition system overall design description and function index of the analysis, the data collected through the transmitting antenna, a receiving antenna, a transmitter, a receiver, a controller, etc. component to achieve. The software module design of data acquisition system including the channel settings, set the trigger, data port settings and data visualization module design and data read playback sub modules, through the software design and implementation of VXI bus data acquisition. The experimental results show that the system has higher performance and better stability, and has higher accuracy of data acquisition, which is the input and output waveform control of the data acquisition system.
