基于LonWorks的节能信息采集管理系统设计

Designing Energy-saving Information Collection and Management Systems Based on LonWorks Fieldbus Technology

针对目前节能信息采集管理系统功能单一、各系统采用不同的总线技术和通信协议导致系统间兼容性差的现状,设计并实现了一种基于LonWorks现场总线统一的节能信息采集管理系统,文中给出了详细的总体设计方案和关键问题的解决方案,设计实现的系统能够提供标准的设备接口,提供全面的节能设备状态监测,完成对系统故障处理、网络性能状况分析的智能化。因此该系统具有扩展容易、组网智能化和施工维护使用方便等特点,加速了用能单位的信息化建设进程。

Because the current saving-energy system of Information collection and management has single function, except that the system uses different bus technologies and communication protocols which leads to poor compatibility between systems, this paper designed and implemented unified energy-saving information collection and management systems based on LonWorks fieldbus. The paper works out in detail the overall design plan and the solution for critical problems. The designed and implemented system can supply standard device driver interface, provide comprehensive status monitoring for saving-energy equipments, handle the system failure and analyze its network performance intelligently. Therefore the system has many features such as easy expansion, intelligent network construction and convenient maintenance, which will accelerate information construction process of energy-using units.
