摘要
针对变电站内电磁环境复杂、红外图像传输速度要求高的特殊情况,提出了一种基于USB2.0和光纤的红外图像采集系统的设计与实现过程。系统以FPGA作为核心处理器,控制光收发一体模块收发红外图像信息,并通过USB2.0接口传送至计算机进行处理,从而为实现变电站红外图像监控提供原始红外信息。该系统具有速度快、灵活、配置简便、不受电磁干扰影响等特点。
Concerning the circumstance of the complex electromagnetic environment in the substation and the request of the high-speed infrared-image transmission, an infrared-image acquisition system based on USB2.0 and optical fiber was proposed. FPGA was used as the core processor to control optical transceiver module＇ s transmission of infrared- images. And infrared-images were transferred tO a computer through USB2.0 to provide the raw infrared-images for the substation infrared-images monitoring. The system is of high speed, simple and flexible configuration, no electromag-netic interference and so on.
