基于nRF905的智能封锁雷无线通讯技术

摘要

This article proposed a method to wireless communication of intelligent blockade landmine based on the radio communication of nRF905. It provided the design scheme and the program flow chart of the communication system on intelligent blockade landmine. For advancing the security and the antijamming performance of data transmission, it adopted AT89S52 as control unit which is a kind of high performance MCU, and realized frequency hopping communication among the nRF905 modules. In this article, it successfully designed the prototype instrument, and did the correlative experiment about antijamming performance, send-receive velocity, effective communication distance. It is proved that the system can realize the data transmission of intelligent blockade landmine effectively.%提出了一种基于无线射频模块nRF905的智能封锁雷无线通讯方法,给出了智能封锁雷通讯系统的设计方案和系统程序流程图.为了提高数据传输的保密性及抗干扰性,采用了高性能单片机AT89S52作为控制部件,实现了nRF905模块之间的跳频通讯.制作了原理样机,并且进行了系统抗干扰性、收发速率、有效通讯距离等室内外相关实验,通过实验证明该系统能够有效地实现智能封锁雷的数据传输.
