摘要:
为了提高特殊狭窄空间设备通信的可靠性,开发了一种基于nRF905的短距离无线数据通信系统。该系统的基本节点由nRF905、STC单片机、DS1302等硬件组成。系统设计了包含独立时间窗和竞争时间窗的时钟同步时间调度表,各节点按时间调度表分时发送和部分竞争发送。竞争时间窗中多个节点的竞争采用随机数退避算法和帧间隔优先级的方法来减小节点发生碰撞的几率。实验结果表明,该系统数据传输效率高、实时性好、可扩展性强, 可广泛应用于各种短距离无线数据通信中。
Abstract:
In order to improve the reliability of communication of the equipment in special narrow space, a kind of short-range wireless data communication system based on nRF905 has been developed. The basic node of the system consists of nRF905, STC series SCM, DS1302 and so on. A clock synchronization time dispatch table is designed which contains separate time windows and competition time windows. Individual nodes have two transmitting modes according to the time dispatch table which are time-sharing sending and partly competition sending. For multiple nodes of competition in competition time windows, a random number wince algorithm and frame interval priority method are used to reduce the probability of node collision. The results show that the system has high data transfer efficiency, high real time and high extensibility, and it can be widely used in a variety of short-range wireless data communication.
