【摘要】：能源是现代经济的命脉。随着传统化石能源的日益枯竭,社会经济的发展受到严重制约。因此,开发利用可再生能源,促进能源结构的绿色转型势在必行。近几十年来,太阳能热利用产业发展迅速,其中太阳能热水系统的应用最为广泛。但是,目前太阳能热水系统的管理效率较低,信息化以及自动化程度仍有待提高。此外,随着合同能源管理节能服务产业的兴起,太阳能热水系统必须具备能量计量以及性能指标的统计分析功能。针对太阳能热水行业发展的需求,研制一种太阳能热水工程数据采集器,具有数据采集、能量计量以及通信中继等功能,通过远程监控服务器能够实现对太阳能热水工程的实时监控与能量计量。对太阳能热水工程远程监控系统的设计架构进行分析,提出数据采集器功能设计和结构设计方案。对太阳能热水工程数据监测与能量计量的方法进行了研究,建立了太阳能热水工程能量输入输出模型,给出了相关计量参数的计算方法。完成了电路模块的硬件设计。完成了嵌入式软件和应用软件的设计,对实时操作系统和文件系统的移植过程进行阐述,针对数据采集器的功能需求进行应用软件设计。由于数据采集器实际应用场合存在信号干扰,容易造成采样信号失真。采用数字滤波技术对干扰信号进行剔除。提出了数据采集器通用性设计的思路,实现了各类参数和计量公式动态配置,使数据采集器能够兼容不同的太阳能热水系统。
[Abstract]:Energy is the lifeblood of the modern economy. With the depletion of traditional fossil energy, the development of social economy is seriously restricted. Therefore, the development and utilization of renewable energy to promote the green transformation of energy structure is imperative. In recent decades, solar thermal utilization industry has developed rapidly, among which solar hot water system is the most widely used. However, at present, the management efficiency of solar water heating system is low, and the degree of informatization and automation still needs to be improved. In addition, with the rise of contract energy management and energy saving service industry, solar water heating system must have the function of energy measurement and statistical analysis of performance index. In order to meet the demand of the development of solar water heating industry, a kind of solar water heating engineering data collector is developed, which has the functions of data acquisition, energy measurement and communication relay, etc. The remote monitoring server can realize the real-time monitoring and energy metering of solar hot water project. The design framework of remote monitoring and control system for solar water heating project is analyzed, and the function design and structure design scheme of data collector are put forward. The methods of data monitoring and energy measurement for solar water heating engineering are studied. The energy input and output model of solar water heating engineering is established, and the calculation method of relevant measurement parameters is given. The hardware design of the circuit module is completed. The design of embedded software and application software is completed. The porting process of real-time operating system and file system is described. The application software is designed according to the function requirement of data collector. Because of the signal interference in the practical application of the data acquisition device, the sampling signal is easily distorted. The interference signal is eliminated by digital filtering technique. The idea of universal design of data collector is put forward. The dynamic configuration of all kinds of parameters and measurement formulas is realized, so that the data collector can be compatible with different solar water heating systems.
