基于DSP的嵌入式车道偏离报警系统的硬件平台

摘要

Recently, the widely used hardware platform for lane departure warning system is industrial PC, but industrial PC is a big size, high power consumption, high cost and low stability solution. In order to overcome these disadvantages, an embedded hardware platform of lane departure warning system is designed. The DM642 is utilized as video capture and processing module, and the system based on C8051F7020 is employed as vehicle parameters acquisition, meantime, the whole system is powered by a power system based on LM2576. Test for the system is taken. The results show that the system is a real-time and high robust one, which can meet the re-quirement of the equipments.%目前普遍采用的车道偏离报警系统的硬件平台是工业PC.为了克服其体积大、功耗高、成本高、可靠性低的缺陷,设计了一种嵌入式车道偏离报警系统的硬件平台.利用基于DM642系统作为视频采集处理模块,采用C8051F040的数据采集系统作为汽车行驶参数采集模块,使用基于LM2576的电源系统为整个系统供电模块.试验表明,该系统具有良好实时性和抗干扰能力,满足了系统设计需要.
