摘　　要：针对偏远地区小型加工厂和家庭用户的电力负荷监控,设计并实现了一种结合远距离无线电(Long Range Radio,LoRa)通信和多跳网络结构(MESH)的电力负荷监控系统。所提出的系统可依据数据源自动选择每个电表节点的功能,并根据实时监控数据在无须人工干预的条件下调整系统结构。为进一步提高系统在偏远地区下的运行可靠性,提出了备用基站的设计方案,可在基站硬件出现故障时正常运行。为降低生产成本并简化制造工艺,采用基于Arduino板的硬件设计。在室内和室外真实环境下的测试结果表明,该系统能够长期、稳定和低成本地实现偏远地区电力负荷地监控。最后提出基于大数据技术的供电政策,为延长离网电厂供电时间提供了一种新思路。Aiming at the power load monitoring of small processing plants and home users in remote areas,a power load monitoring system combining Long Range Radio(LoRa) communication and multi-hop network structure(MESH) is designed and implemented.The proposed system can automatically select the function of each meter node according to the data source,and adjust the system structure according to the real-time monitoring data without manual intervention.In order to further improve the operating reliability of the system in remote areas,a design scheme for a standby base station is proposed,which can operate normally when the base station hardware fails.In order to reduce production costs and simplify the manufacturing process,a hardware design based on the Arduino board is adopted.Test results in real indoor and outdoor environments show that the system can achieve long-term,stable and low-cost monitoring of power loads in remote areas.Finally,a power supply policy based on big data technology is proposed to provide a new idea for extending the power supply time of off-grid power plants.
