【摘要】 本文旨在进行城市集中供热网运行监控系统平台的设计。有效的热网监控系统，有利于企业提高生产效率，增加经济效益。在针对目前集中供热网监控系统存在的问题进行分析的基础上，本文提出了基于GSM Network的热网SCADA系统平台的总体设计方案。 该热网SCADA系统平台不但实现对集中供热网的有效监控，而且为热网最终实现合理调节、控制提供了有效的手段。针对以往热网监控系统难于扩展的问题，本平台设计通过与系统数据库进行动态连接，利用ADO访问方式中的Execute方法实现系统动态扩展的功能，可以根据需要任意扩展系统包含的热力站点。考虑到系统平台在以后应用过程中控制方法可以不断优化、改进，在平台中特别预留了相应的接口，通过接口调用相应控制算法编制的动态连接库实现系统总体优化、控制的功能。同时，针对过去监控系统因采用无线电台通讯而出现的数据容易丢失的问题，设计时采用基于GSM Network短消息服务的无线通信方式，保证系统间数据传输的质量，从而进一步保证了系统运行的可靠性。 本文设计的热网SCADA系统平台具有易于扩展、操作简单、系统的安全性及稳定性较高等特点，并为热网的进一步研究提供了可靠的研究平台。更多还原

【Abstract】 In the article, a monitoring platform for the district heating network of modern city is introduced. Effective monitoring system for heating network can help the enterprise to improve the productive efficiency and economical efficiency. Through analysis of traditional monitoring system for district heating network, the SCAD A platform for district heating network based on GSM Network is put forward finally.The SCAD A platform not only implements effective supervision for the district heating network, but also supplies a method to adjusting and controlling the district heating network. Aiming at the difficulty for district heating network expanding, the platform is developed to connect database dynamically. Using Execute method of ADO model to implement dynamic expanding of the platform. So, the heating network can add new station discretionarily when it need. And because the control method used by the platform could be improved on and optimized during application course, the platform reserves interface for control function. It gives facilities for the platform to implement total system optimization by embedded relevant control algorithm. At the same time, aiming at the data-losing problem of traditional monitor system, the SCAD A platform adopts short message service based on GSM network to ensure the communication quality. Thereby the function of the platform is ensured farther.The SCADA platform project of district heating network expatiated in this article has some characteristics including handling facility, expandability, high security and stability etc. It provided reliable research platform for district heating network advanced research.更多还原
