Description
TECHNICAL FIELD
[0001] The utility model relates to the field of industrial control especially is related to a novel refrigeration cabinet controller. BACKGROUND
[0002] The refrigeration display cabinet is first applied to the medical industry and is mainly used for preserving medicines and biological products. With the development of the food industry, the refrigeration cabinet is gradually introduced into the commercial field and is used for displaying and preserving food. With the progress of science and technology, the modern refrigeration cabinet integrates various advanced technologies, such as an intelligent temperature control system, energy-saving and environment-friendly technology, etc., which significantly improves the refrigeration effect and user experience.
[0003] The refrigeration cabinet is widely used in supermarkets, convenience stores, hotels, restaurants and other places and is used for displaying and preserving various food, such as beverages, dairy products, cooked food, etc. When the control parameters of these refrigeration cabinets need to be set, the related control parameters are usually configured or adjusted by directly operating the control panel or the remote host setting mode. Or the automatic adjustment can also be realized through a complex PID control strategy. However, in order to avoid non-staff setting the refrigeration cabinet, the refrigeration cabinet usually does not set the corresponding man-machine interface, so the control panel cannot be used. The refrigeration cabinet with the man-machine interface needs to set the account password in advance, and the remote host adjustment needs the refrigeration cabinet to have the remote communication function. The PID automatic adjustment mode needs a complex control strategy and has a high cost. SUMMARY
