nRF2401在家居防盗中的应用

【内容摘要】 在监控系统中,数据从采集设备到处理终端,监测控制指令从处

理终端到采集设备,均需经过传输过程这一重要环节。当数据采集点处于运动状态,或者所处的环境不允许铺设电缆,采集设备必须与终端设备分离,此时只能通过无线方式进行数据传输。本文介绍的无线数据传输系统, 主要由AT89C51单片机和无线数字传输芯片nRF2401组成。本系统通过无线方式进行数据传输,两端采用半双工方式通信,两端数据传输模块完全通用。该系统成本低廉,可方便地嵌入到智能家居系统中。

Abstract

In the monitoring system, not only data from collection equipment to the handle terminal but also monitor control commands from the handle terminal to collection equipment needs an important part of transmission process. When the data collection points in motion, or the environment does not allow to laying the cables, collection equipment and terminal equipment must be separated, at this time there is only way of wireless to transmit the data. In this paper, a system for the wireless data transmission is introduced, which mainly consists of a microcontroller of AT89C51 and nRF2401 which is a chip for wireless digital transmission. This system transmits the data through wireless. Both ends of this system use the way of half-duplex mode to communicate and its modules for data transmission at both ends are completely universal. The cost of this system is low and it can be easily embedded in the smart home system.
