首发时间:2019-05-05
摘要:针对于当前森林环境监测与森林防火工作设备维护困难以及耗费人力多的问题,本文提出了一种基于LoRa无线通信技术的森林环境监测系统设计,以实现远程环境监测、森林火灾报警及森林火情定位功能。系统构建了多层次中继节点的通信网络,合理的冗余机制保证了通信网的可靠性。不同环境条件下,数据采集设备采用不同算法实现工作的低功耗。当火情发生,远程监控端能迅速完成火灾报警与火情定位。测试结果表明,系统数据传输准确,设备功耗低,可以较好的满足森林环境监测的需求。

Design of a Forest Environment Monitoring System Based on LoRa
Abstract:In view of the current forest environment monitoring and forest fire prevention equipment maintenance difficulties and labor-intensive problems, this paper proposes a forest environment monitoring system based on LoRa wireless communication technology to achieve remote environmental monitoring, forest fire alarm and forest fire locating. The system constructs a communication network of multi-level relay nodes, and a reasonable redundancy mechanism ensures the reliability of the communication network. Under different environmental conditions, the data acquisition device uses different algorithms to achieve low power consumption. When the fire occurs, the remote monitoring terminal can quickly complete the fire alarm and fire location. The test results show that the system data transmission is accurate and the equipment power consumption is low, which can better meet the needs of forest environment monitoring.
