Refrigeration device intelligent maintenance system based on radio frequency technology

Abstract

The invention relates to the technical field of refrigeration device control, in particular to a refrigeration device intelligent maintenance system based on radio frequency technology. The refrigeration device intelligent maintenance system based on the radio frequency technology comprises a master control module, a radio frequency module, a state monitoring module and a state control module, wherein the radio frequency module, the state monitoring module and the state control module are connected with the master control module in action mode. In a production process, the radio frequency module has an identity recognition function, and a manual radio frequency reader-writer reads assembly information in the radio frequency module. If the information is unmatched, and the radio frequency module returns to a station starting stage to perform inspection and verification until assembly is correct. When a refrigeration device product is operated, the state monitoring module acquires operation information of a refrigeration device and sends the operation information to the master control module, faults of the device can be found in real time or in advance through analysis processing of the master control module, the faults can be found in time, and loss is avoided. In a whole life cycle, the radio frequency reader-writer reads the radio frequency module in the system, the information is uploaded to a feed-back system of a manufacturer, and follow-up service of sold products is performed well.

Description

technical field [0001] The invention relates to the technical field of refrigeration equipment control, in particular to an intelligent maintenance system for refrigeration equipment based on wireless radio frequency technology. Background technique [0002] With the continuous improvement of economic development and people's living standards, the consumption of frozen products such as yogurt or ice cream is increasing, and the market demand for refrigeration equipment such as yogurt machines or ice cream machines is increasing year by year. [0003] At present, there are many problems in the production and post-maintenance of refrigeration equipment, which are mainly reflected in the following aspects: 1. During the production and manufacturing process of refrigeration equipment products, automatic assembly lines are used for assembly. At present, there is a lack of effective supervision measures to ensure that the parts in the assembly process The correctness can only be i...

Problems solved by technology

[0003] At present, there are many problems in the production and post-maintenance of refrigeration equipment, which are mainly reflected in the following aspects: 1. During the production and manufacturing process of refrigeration equipment products, automatic assembly lines are used for assembly. At present, there is a lack of effective supervision measures to ensure that the parts in the assembly process The correctness can only be inspected after the assembly process is completed and before leaving the factory. If there is a wrong assembly, the parts will be dismantled and returned to the assembly line, which is not only inefficient, but also increases time and labor costs; , the lack of effective technology can detect equipment failures in advance or in real time. The consequence is that if the refrigeration equipment fails, it cannot be discovered in time, and it has already caused losses to users when it is discovered; 3. During the entire life cycle of refrigeration equipment, manufacturers There is a lack of efficient and time-saving means to identify and track sold equipment, and data collection and tracking of historical information such as failure occurrences and maintenance requires manual sorting and collection. The workload is heavy, and it is often difficult to achieve correct statistics. Difficult to do effective tracking service
