摘要
分析了现有有线超声波车位检测器存在的问题,在此基础上,提出了一种基于无线射频技术的车位检测器,并详细描述了系统原理、硬件设计和具体实现细节。无线车位检测器构成一个无线传感器网络,可以实时地监测车位占用情况。该检测器有安装方便,安全可靠,价格便宜等优点。
The current problem of parking lots detector is analyzed. A kind of detector which is based on wireless RF technology is presented. A lot of detectors combine a wireless sensor network. The sensor' s information can be easily gathered. The detector has many characters, such as easy to instal, reliable, safe and cheap.
