摘要
介绍了UWB高精度定位系统中标签的设计,标签是一种便携式、低功耗无线通信模块。本设计是基于C8051F921单片机和nRF24L01低功耗无线收发芯片组成的硬件结构,设计包括电源的设计,采用了尺寸较小的锂电池。UWB窄带脉冲可以达到纳秒级,延时抖动延时完全在允许的范围内。最终设计的标签实现了在系统的控制下,完成数据收发,使定位精度在30cm内。
The design of the sag, in UWB high precision location system, was introduced, since tags is a portable, low-power wireless communication module. The hardware structure of his design is based on C8051F921 MCU and RF24L01 low power consumption of wireless transceiver chip, including the design of smaller lithium battery as power supply, UWB narrow pulse can reach nanosecond, delay jitter completely within the permitted range. In this design, data transceiver of the sag under the controlling of the system can be realized, with the location accuracy reaching up to 30 cm.
