Refrigerator refrigeration performance measurement and control platform based on computer control

Abstract

The invention discloses a refrigerator refrigeration performance measurement and control platform based on computer control. The platform comprises a computer, and a switching value controller, a data acquisition device and an interface converter which are electrically connected with the computer, a field bus electrically connected with the interface converter, and a digital indication adjuster and a touch screen which are electrically connected with the field bus. According to the platform, the switching value controller and the data acquisition device are enabled to individually occupy one RS232 COM serial communication port of the computer, individual communication lines are respectively occupied, timeliness of the switching value controller and the data acquisition device is relatively high, moreover, communication between the switching value controller and the computer belongs to single-machine communication, programming of a communication module of the switching value controller is relatively simple, communication can be realized without the address identification data, the communication data is reduced, and relatively high efficiency is realized.

Description

technical field [0001] The invention relates to a measurement and control platform, in particular to a computer-based refrigeration performance measurement and control platform of a refrigerator, which belongs to the technical field of computer intelligent control. Background technique [0002] The initial refrigerator refrigeration performance test system was manually operated and read. The stability, accuracy and immediacy of the test system could not be guaranteed. With the emergence of new technologies and materials, polyphenylene and polyurethane insulation boards replaced the original bricks. As the enclosure structure, the mixed wall reduces the heat leakage of the system and reduces the energy consumption. With the development of control technology, advanced control theory is applied to the control of laboratory temperature and humidity, so that the test environment is guaranteed. The accuracy of the results has been improved; the continuous improvement and developme...

[0002] The initial refrigerator refrigeration performance test system was manually operated and read. The stability, accuracy and immediacy of the test system could not be guaranteed. With the emergence of new technologies and materials, polyphenylene and polyurethane insulation boards replaced the original bricks. As the enclosure structure, the mixed wall reduces the heat leakage of the system and reduces the energy consumption. With the development of control technology, advanced control theory is applied to the control of laboratory temperature and humidity, so that the test environment is guaranteed. The accuracy of the results has been improved; the continuous improvement and development of refrigerator performance testing technology can promote the improvement of refrigerator performance and promote the progress and prosperity of technology in the whole industry. , and does not conform to the long-term interests of the country. Therefore, it is necessary to conduct research on the automatic refrigerator refrigeration performance measurement and control system, and develop a system with low energy consumption, strong versatility, perfect control functions, efficient data processing, centralized display operation, and human-machine interface. A measurement and control system with the characteristics of friendliness, convenient debugging, safe and stable operation, and low cost
