基于ARM的红外激光测速与数据传输系统设计

摘要

针对目前车辆测速误判率较高,精度较低的现状,提出一种基于ARM的红外激光测速与以太网传输系统.该系统采用了LPC2103作为主处理器,TDC-GP2作为测速芯片,利用以太网控制芯片ENC28J60实现系统与PC机的连接,完成数据采集与传输功能.系统体积小,结构简单.模拟实验结果表明:系统可准确测量车速,并能快速可靠地传输数据.%Aimed at the condition that the velocimetry has high rate misjudgment and low precision. An infrared laser velocimetry and ethernet transmission system is proposed. The system is based on ARM. LPC2103 is adopted as the main processor of the system. TDC_GP2 is adopted as the velocimetry chip. In order to complete data transmission,the ethernet controller chip ENC28J60 is adopted to accomplish the link between system and PC. Simulation experiment show that the system can complete data transmission reliably and quickly with the standard ethernet.
