摘要
湖南地区的小水电多分布在偏远山区,部分电站无运营商网络信号覆盖,影响调度数据采集。本文通过引入LoRa无线传输技术,利用线性扩频调制进行中继传输,结合前向纠错技术(FEC)进行远距离、低功耗通信,并合理选择数据采集装置的电源接入方式,从而实现对无公网信号地区小水电调度信息的分钟级采样。
Small hydro-power plants in Hunan province are often located in remote mountainous regions with poor mobile signal, which has an effect on dispatch data acquisition. This paper brings long range(LoRa) wireless transmission technology to achieve long-distance and low power consumption communication by using linear spectrum extension modulation combined with front effect correction(FEC) and properly choosing the power supply mode of the data acquisition.With LoRa technique, dispatch information in those areas where there is no mobile signal can be successfully acquired and sampled every minute.
