小区车辆进出的激光自动检测研究

Research on the automatic detection of the vehicle in and out of the district

采用信息化手段管理小区车辆进出是一个大的发展趋势,可以快速辨别登记车辆,准确限制未登记车辆进出小区,因此小区车辆进出管理研究具有重要的意义。传统检测系统采用普通传感器实现,使当前车辆自动检测系统存在数据丢失率大、应用局限性等缺陷,设计了一种新型的小区车辆进出的激光自动检测。首先对当前小区车辆管理的研究现状进行分析和研究,并指出了它们不足产生的原因,然后利用激光传感器采集车辆数据,将车辆数据传给登记车辆身份卡进行编码、调制与解码,自动检测车辆进出小区权限,最后采用电子标签登记车辆身份卡,抵抗身份冲突和卡片复制,并通过具体仿真实验对系统的有效性和优越性进行检测,实验结果表明,小区车辆进出激光自动检测系统的数据丢失率和数据差异率小,具有较高的实际应用价值。

Informational management of small vehicles is a big trend. It can quickly identify the vehicle registration, accurately limit nonregistered vehicles. So itis important to study the management of in and out of small vehicles. The traditional detection system is realized by ordinary sensor. In view of the defects of current vehicle automatic detection system, such as the large loss of data, a novel automatic vehicle detection for in and out of the cell is designed. Firstly, this paper analyzes and studies the current situation of the research on the management of vehicles insmall area, and points out the causes of their deficiencies. Then, the data of vehicle is acquired by laser sensor, and vehicle registration data is transformed to the vehicle identity card for encoding, modulation and decoding. And realizing automatic detection of vehicles. Finally, electronic tag is used to register vehicle identity card which is resistant for identity conflict and card copy. The experimental results show that data loss rate and difference of the proposed automatic detection system are small, and it has high practical value.
