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。
It is a big development trend to use informational means to manage the vehicles in and out of a residential area. It can quickly identify the registered vehicles and accurately limit the unregistered vehicles to and from the residential areas. Therefore, it is of great significance to study the access control of residential vehicles. The traditional detection system uses the common sensor to realize the automatic detection system of the vehicle has the defects of large data loss rate and application limitations, and a new type of automatic detection of the vehicle entering and leaving the area is designed. First of all, the current status of community vehicle management research and analysis, and pointed out the causes of their shortcomings, and then the use of laser sensors to collect vehicle data, the vehicle data transmitted to the registration vehicle identification card encoding, modulation and decoding, automatic detection of vehicles Access to community permissions, and finally the use of electronic tag registration vehicle ID card, to resist identity conflicts and card replication, and through specific simulation experiments to test the effectiveness and superiority of the system, the experimental results show that residential vehicles out of laser automatic detection system data loss Rate and data difference rate is small, with high practical value.
