full closed refrigeration compressor application status and performance test bed development system parameters of intelligent instruments the PC through the RS485 bus,hollister deutschland, successor, the data transfer using the MODBUS communication protocol MODBUS communication protocol is a common agreement can be adapted to the most intelligent instruments. The database system uses the ACCESS database,hollister carugate, ACCESS database has good data organization and to facilitate the search,ralph lauren, has brought great convenience to the data storage and organization. This software can be a cycle store data,hollister neuss, in order to adapt to different response speed; data storage time can be artificially set up a year; data search time search-based, you can search the data from different time periods in order to facilitate search of a variety of historical data. The interface display system provides a wealth of information, the interface system is mainly composed of the main interface, curve interface,hollister euroma2, a variety of reports interface. The main interface shown in Figure 2. The main interface to the physical form of the process of the test bed system, a variety of media flow direction at a glance, and this interface can display the values ​​of various parameters in real time, intuitive and easy. Figure 2 the main interface in March 2007 26 1 (98) refrigeration five real-time curves of real-time trend curves drawn has been one of the difficulties of software design. We designed the curve interface real-time curve interface, historical curve interface is user-friendly. Typical history curve shown in Figure 3, the interface shows multiple parameters of the curve, so that the operator have a comprehensive understanding of the entire experimental process; curve can be adjusted to facilitate the observation; curve printing, save fully functional. The other curves interface also has the same function. The report interface each time period available experimental data,hollister, display data can be stored in files, print. The report interface provides a great convenience to the researchers analyze the data.

Test computer running more than two years, has been stable performance, economical and practical performance of the compressor experiments and understand the system, and laid a solid foundation for graduate students and teachers. The test stand can be further developed to meet the different needs of product testing and teaching and research. References [1] Li Wenhua, Google.
