| Ground source heat pump system is an important part of renewable energy applications and an important means of building energy efficiency. In recent years, countries make progress of the ground source heat pump buildings, but also to strengthen the evaluation and assessment of the ground source heat pump demonstration project outcomes. In order to understand the energy efficiency in building applications of ground source heat pump system, compose the evaluation standard for application of ground source heat pump in buildings, energy-saving programs and tap the energy potential, the country is gradually advancing renewable energy data monitoring system of the building.During my graduate course, I took part in the evaluation and acceptance of ground source heat pump building demonstrating projects in Shandong province; There are no data processing and analysis capabilities found in the work of data-collecting devices currently in use, only uploading the raw data, but no analysis capabilities, the practical value of data is not high. If you increase the analysis capabilities will enable the construction of ground source heat pump project applications data-collecting system more practical value.So,this task is based on the practical application,methods according to related national standards, the main content of the topic is computer measurement and control technology,based on the ARM microprocessor hardware platform,designed the data monitoring system of ground source heat pump construction applications (referred to as "data monitoring system").Data monitoring system is a three layers network architecture, including data acquisition layer, data transport layer, and data management layer. The projects focused on the design of hardware and software in the data collection and the transport layers, and the design of transmission network, not include the design of the data management. It includes: determine function of the system, determine the data monitoring network structure, determine the parameters to be collected, select monitoring equipment,design the hardware circuit of data management machine and develop the driver, the development of data monitoring software, overall system debugging and simulation application in the experiment environment.Data monitoring system of ground source heat pump construction achieved online, long-term effective monitoring and the assessment of energy savings effect in the construction of ground source heat pump application, providing support to the calculation of energy-saving effect in ground source heat pump building applications in the future.The data which the system collects including is building information, information of demonstration project, flow, temperature and electricity usage, in which the information of buildings and project entered into the system database manually.The concept of energy monitoring system in public buildings is applied into assess the use of ground source heat pump project construction applications in this topic, which solved the problems data-collecting device lack of processing and analysis capabilities of the data, obtained the analyzed data, energy-saving project evaluation report is used for the acceptance of the demonstration projects provided accurate and objective basis, the report can be used as guidance documents in heat pump manufacturer’s transformation at the same time. |
