In order to solve the problems of the current solar water heater testing system need technicist to select the data, the poor ability of automatic calculation and the single representation of performance parameters, the Windows communication foundation( WCF) technology was applied to the remote data acquisition. After the analysis of the principle of solar water heater performance testing and WCF remote communication , the relation between local data capture system and data center was established , combining with the . Net development platform, the solar information remote monitoring system based on WCF was developed. The design and realization method of the system was presented. The data from the existing testing system was sampled, on the basis of this, many features were developed, such as the calculation, data display, data for classing and saving, reports generation and so on. Performance parameters such as solar heat gain and heat loss coefficients can be calculated automatically. The results indicate that the system can sample the data steadily and calculate the parameters precisely, it also can seamlessly integrate into the current testing system, help to improve the efficiency of testing.%为解决现有太阳能热水器测试系统人工筛选数据、自动计算能力差及性能参数表现单一等问题,将Windows通讯接口技术(WCF)应用到远程数据采集中.开展了太阳能热水器性能测试原理及WCF远程通信的研究与分析,建立了本地数据采集系统与远程数据中心之间的关系,结合.Net开发平台,开发了一套新型的太阳能热水器性能远程监测系统,并提出了系统设计及实现的方法;对太阳能热水器测试系统的数据进行了远程采集,在此基础上开发了计算分析、数据显示、数据分类存储、报表生成等功能,以自动计算出系统的热量、热损系数等相关性能参数.研究结果表明,该远程监测系统数据采集稳定,计算结果准确可靠,通过将该平台无缝集成到现有测试系统中,提高了测试的效率.
