摘要
针对当前流行的短距离无线通信做了研究比较,利用Nanotron技术搭建一套无线测距系统。系统采用了以射频收发器NanoLOC TRX为核心,ATmega664V为微控制器的NanoLOC AVR模块,以WinAVR为基本的软件开发平台。在程序调试过程中,根据实际需要将数据传输模式设置为Auto-Si mplex模式。通过大量的实验证明,该系统在250 m的传输距离上把误差缩小到4 m以内,测量精度较高,系统较稳定,实现了一种新的无线测距方法。
The modes of current popular short-range wireless communication are studied and compared. A set of wireless location system was built wit Nanotron technique. The NanoLOC AVR modules which takes RF transceiver NanoLOC TRX as a core and ATmega664V as a micro-controller are adopted in the system, which employs WinAVR as a basic software development platform. In the process of program debugging, the data transmission mode is set as Auto-Simplex mode according to the actual need. A lot of experiments show that the system error is less than 4 m while the transmission distance is 250 m, the measurement accuracy is high, and the system works stable. It is a new wireless ranging method.
