Refrigeration Cycle Comprehensive Test-bed Visualization And Monitoring System Development

With the continuous improvement of the level of industrialization, Computer has been widely used in the field of industrial control, Industrial control systems are developing in large and complex control direction, meanwhile, the high requirements of the degree of industrial automation, making a wide variety of control devices and process monitoring device has been applied in the industrial field. Information technology for the automation was the development at the same time, also makes automation systems increasingly high demand for employees. In this paper, combined with the laboratory process of transformation, using the configuration software on the computer to establish the simulation of the experimental system, simplify the complexity of the experimental operation,improve the efficiency, reduce the requirements for laboratory personnel, completed the process of human-computer interaction, has a certain Engineering significance.The configuration software, use its own gallery and dynamic graphics, to establish the simulation of the test system, complete dynamic simulation of the experimental, the same time, through the establishment of real-time database systems and on-site data collection devices to the formation of communication, used to monitor the experiment data changes. Thus the formation of a database system based on dynamic simulation of refrigeration cycle performance bench, convenient to storage of experimental data and shown in the simulation process, the visualization of the operating environment, so that the experiment is easy to operate.This article introduces the concepts and features of the configuration software, Refrigeration cycle performance test-bed for instance, the analog interface design process, focus on the real-time database system configuration software, explicit correspondence between the database point variables and on-site monitoring points, Completion of a data exchange, establishment Interactive interface. The complete system data collected at the same time, so that the data changes in a timely manner shown in the computer interface. Ultimately, the establishment of a real-time database as the core, set the host computer, data acquisition module, sensor, measured point, visualization, data acquisition system. Basically solved the experiment, the data acquisition category, quantity, the synchronization requirements of the problem of high, at the same time, this paper presents the configuration software to connect the Microsoft DDE data exchange system module, to solve the compatibility problems of the configuration software and data acquisition equipment, complete data synchronization, and improved scalability. In actual operation, to achieve the synchronization of data acquisition process.In the early transformation of the experimental station, the configuration software tools to develop a dynamic simulation interface of the circulatory system of the refrigeration cycle performance bench, complete a part of the data collection, established the basic simulation experiment prototype, laid the foundation for the further improvement of the bench, provides a reference.
