摘要
分析了传统的基于PC的停车场控制器后发现,传统的停车场控制器具有受停车场规模的限制,布线复杂,以及未考虑到保障车辆在停车场中安全等缺点。为解决这些缺点,新型的停车场控制器采用嵌入式ARM系统来保证实时性和可靠性提高集成度,同时集成了SAA7115视频解码芯片,实现了实时补光选优算法,并支持后端车牌号牌自动识别,从而提供停车场内车辆的安全保障。经过大量测试和实际使用证明了该智能控制器具有高可靠性、稳定性以及很好的安全保障能力因此能够很好替代现有的传统停车场控制器。
On the traditional parking controller based on PC is researched which have some defects such as limited by the size of parking lot,wiring complexity,ignored the safety of cars in parking lot.To overcome this,the new type parking controller uses embedded ARM(advanced RISC machines) system to ensure real-time,stability and improves the integration.At the same time it integrates the SAA7115 video input processor,to achieve the real-time optimal selection algorithm for fill light and provide the back-end automatic license plate recognition and security capabilities of the car that park in parking lot.By a great deal of tests and practicalities,it is certificated that PIC can provide high reliability,stability performance and good security capabilities to instead of traditional parking controller.
