方案概述

针对城市大渠路灯维护和控制难的问题,我们设计研发了太阳能路灯监控管理系统。

1、监控节点责任对太阳能电池板、输出电压、工作电流、锂电池的充放电压和容量等参数进行采集,

2、通过距离2/4G无线通信模块NRF2401讲数据放松到相邻的节点,直至路由到管理节点。监控中心通过软件对所有路灯运行状态进行接收,处理,分析,显示和储存,

3、将监控中心的操作指令下达给每个节点。

该系统准确获得路灯参数为城市照明系统的运行和维护提供了强有力的技术保障,提高了城市照明智能化管理水平。

【nrf2401】

nRF2401是单片射频收发芯片,工作于2.4～2.5GHz ISM频段,芯片内置频率合成器、功率放大器、晶体振荡器和调制器等功能模块,输出功率和通信频道可通过程序进行配置。芯片能耗非常低,以-5dBm的功率发射时,工作电流只有10.5mA,接收时工作电流只有18mA,多种低功率工作模式,节能设计更方便。其DuoCeiverTM技术使nRF2401可以使用同一天线,同时接收两个不同频道的数据。nRF2401适用于多种无线通信的场合,如无线数据传输系统、无线鼠标、遥控开锁、遥控玩具等。

【nRF2401A】

Low power 2.4GHz RF Transceiver IC

DESCRIPTION

This product is not recommended for new designs. Nordic recommends the nRF24L01+ or for a System-on-Chip solution either the Nordic nRF24LE1 or nRF24LU1+.

The Nordic nRF2401A is a highly integrated, ultra low power (ULP) 1Mbps RF transceiver IC for the 2.4GHz ISM (Industrial, Scientific and Medical) band. With peak RX/TX currents lower than 20mA, a sub μA power down mode, advanced power management, and a 1.9 to 3.6V supply range, the nRF2401A provides a true ULP solution enabling months to years of battery lifetime when running from coin cells or AA/AAA batteries. In addition, its ShockBurst™ hardware protocol accelerator offloads time critical protocol functions from the application microcontroller enabling the implementation of advanced and robust wireless connectivity with low cost 3rd-party microcontrollers.

The nRF2401A integrates a complete 2.4GHz RF transceiver, RF synthesizer, and baseband logic including the ShockBurst™ hardware protocol accelerator supporting a high-speed SPI interface for the application controller. No external loop filter, resonators, or VCO varactor diodes are required, only a low cost 16MHz ±30ppm crystal, matching circuitry, and antenna.

The nRF2401A is available in a compact 24-pin 5 x 5mm QFN package.
