摘要：为了实现基于多源异类传感器的目标检测与识别，需要传感器采集控制设备能够同时对多传感器进行控制与多通道高速数据采集处理。本文设计采用Xilinx FPGA搭载DDR3作为高速数据处理控制板卡，在FPGA内部实现通用CAN总线对多个异类传感器同步外触发控制工作，同时采集多通道高速异类数据并进行预处理与数据缓存，采集数据按类型分别叠加时空同步标识信息，经过归一化处理后通过标准SFP+接口输出，为后续的多传感器信息融合处理提供了统一的、精确的时空同步数据源。

Abstract： In order to realize the target detection and recognition based on multi-source heterogeneous sensors information fusion processing. Sensor acquisition and control equipment is needed to control multi sensors and multi channel high speed data acquisition and processing. In this paper, the design of Xilinx’s FPGA with DDR3 as high speed data processing control board. Implementation of universal CAN bus in FPGA internal trigger control for multiple heterogeneous sensors. At the same time, multi channel high-speed heterogeneous data is collected and pre processed and data cache.Data collected by the superposition of space and time synchronization symbol information,After the normalization process, the output of the standard SFP+ interface provides a unified and accurate spatial and temporal synchronization data source for the subsequent multi sensor information fusion.

Key words： Multi-source heterogeneous sensor; High speed processing; Space time synchronization
