摘要:

为了解决人工抄表数据可靠性不高、抄表不便捷、用户缴费困难等一系列问题,现提出一种基于LoRa调制技术的无线智能水表系统的设计方案：该方案以LoRa调制技术为核心,采用星型、链型网络进行自组织网络设计,构建了通信距离远、功耗低、可抵抗多种干扰源等复杂网络环境下的智能水表系统。在论述系统的过程中重点阐述了智能系统的软硬件设计方案和应用层自定义网络协议,以及智能水表数据采集和远程管理的软件设计方法,在方案设计的最后进行了系统测试分析,测试结果表明了基于LoRa的智能水表系统在通信距离和功耗上具有明显优势。这些优势给LoRa无线通信技术未来构建大规模自组织网络提供了可能,在远程抄表领域该智能水表系统有着广泛的应用前景。

Abstract:

In order to solve a series of problems such as the artificial meter reading system with low reliability,inconvenient for reading-meter and difficulty in users"pay cost,it is put forward a design scheme based on LoRa modulation technology of wireless intelligent water meter system:The project treating LoRa modulation technology as the core,adopt the self-organizing networks" design of the star network and chain network,which build a complicatedly intelligent water meter system with the long- distance communication,low power,resisting different interfering source.It is emphasized that software and hardware design project of the smart system、self-define network protocols in application layer、the software design project about data acquisition and remote management.In the end of the project,It is analysed the whole system"s test property, the result of which indicates that the intelligent water meter system based on LoRa has an obvious advantages in the communication distance and power consumption.These advantages make it possible for LoRa wireless communication technique construct large-scale self-organization network in the furture.And the system has a broad application prospect in the filed of automatic remote meter reading.
