摘要
车位检测是停车场监管系统的重要内容,针对大型地下车库的多通道结构和环境特征,提出了以通道为单元的车位检测方案。该方案以单片机AT89S52为核心,基于超声波探头和环形线圈传感器,通过对车辆行驶方向(进入或离开通道)的判断实现对地下车库车位检测。研究内容主要包括环形线圈电路设计、超声波收发电路设计以及基于单片机的车位检测软件设计。实验表明:系统能有效检测车位信息。
Information detection of parking spaces is one of the important contents of parking lot supervisory system. In view of the multi-channel structure and environmental characteristics of large-scale underground garage,this paper designed a parking space detection system,which utilizes the channel as a unit. Based on sensors of ultrasonic probes and loop detector,the designed system using single-chip microcomputer AT89S52 as core realizes the parking space detection of underground garage according to vehicles＇ driving direction（ entering or leaving the channel）. The research comprises loop detector circuits,ultrasonic receive-emit circuits,and the design of software. The experimental results show that the system is effective in parking space detection.
