【摘要】 针对现代楼宇机电设备多、监控分散而不能整体调度的情况,介绍分布式三级测控网络系统的设计与实现方法,包括基于RS-485总线结构、运用VC++多线程开发监控软件实现现场设备系统的集中监控与数据管理;基于B/S结构、运用WEB数据库访问技术实现远程实时监测与数据分析。提出了基于VC的ADO数据库访问技术设计开发楼宇设备数据管理与分析系统的方法。系统实现了各楼宇设备的总体运行分析、数据检索编辑、运行曲线分析、数据统计分析及报表打印等设备运行分析功能,同时采用统计数据库与历史数据库分开管理、统一表字段格式,有效解决了因系统设备多、数据量大而带来的数据管理与统计难题。
【Abstract】 Aiming at the situation that monitoring for building equipments was separated and unable to be managed as a whole,the design and implement method of distribute three levers monitor and control network system were represented,a configuration of RS-485 bus and B/S,a data management and analysis method for building devices using VC++ multithread-ing,data-base WEB accessing technique were also described.Database accessing method of realizing the equipments’ con-centrate monitor and control based on the technique of ADO developed.The system has functions such as of operation ana-lyzing,data searching and editing,running curve and data statistics,printing of report forms,etc.According to the fact that the running data stream is great and uneven,statistics database and historical database were used to manage and store data,and it makes the system operate conveniently and efficiently.
