| 摘 要： | 提出一种基于FPGA的安全光幕的设计方案，不仅实现了传统安全光幕的探测给定区域有无物体的功能，还加入了计算物体存在时间的功能，加强了安全光幕对物体的判断能力。该设计方案主要由发射模块、接收模块、计时模块组成。因力FPGA编程灵活，发射模块和接收模块轻松地实现了同步工作。计时模块可以通过改变系统主时钟频率来改变计时精度。整个系统在Quartus Ⅱ 8．0设计环境下设计实现，采用Altera公司的EPIC3T144C8型FPGA芯片进行仿真，仿真结果很好地实现了该方案的设计功能，并满足高精度、高速度的设计要求。

| Abstract: | A design scheme of safety light curtain based on FPGA is introduced.It not only achieves the function which traditional safety light curtain has of detecting existence of objects in the given region,but also adds the function of calculating existence time of objects.It can strengthen the capacity which safety light curtain has of judging the objects.The design scheme is composed of emission module,receiver module,timing module.Programming is flexible in FPGA,so it is easy to achieve the synchronization of e... |
