多模组网技术在四表合一采集中的应用研究

Application Research of Multi-Mode Networking Technology in Four-in-One Collection

四表合一采集涉及到将智能水、电、气、热表信息集成到一个统一的平台技术,现场采集组网条件复杂。文章通过对智能水、电、气、热表现场通信状况的分析,提出了基于GPRS、光纤远程通信;基于低压电力线载波、微功率无线、M-BUS、RS-485等本地通信的集成方案。将上述多种通信方式集成到采集设备应用于现场组网,满足了复杂环境下的多计量与采集设备的自组网要求,提高了采集效率及采集成功率。

Four-in-One collection involves integrating the information of smart water, electricity, gas and heat meters into one unified platform, so the networking conditions for site collection are very complicated. In this paper, remote communication based on GPRS and optical fiber is put forward through the analysis of the site communication of smart water, electricity, gas and heat meters. An integration scheme based on local communications such as LV power line carrier, micro-power wireless, M-BUS and RS-485 is also pro- posed. Integrating the above-mentioned multiple communication modes into the collection device for site networking meets the self-networking requirements of multi-metering and the collection device in a compli- cated environment and will improve the collection efficiency and success rate.
