Problems solved by technology

[0004] Currently, some ice recognition systems are integrated inside the freezer, which can be used to identify the accumulated ice in the freezer, so as to facilitate subsequent fault recording and ice removal. However, due to the complexity of the internal environment of the freezer, the accumulated ice in the previous moment The ice body may have melted at a later moment, and it is obviously inappropriate to perform fault recording and ice removal processing at this time. Provide valid reference data

Embodiment Construction

[0029] The implementation of the freezer operation failure analysis platform and method of the present invention will be described in detail below with reference to the accompanying drawings.

[0030] A freezer, also called a freezer, is a device for storing food and other items at low temperatures. There are two types of household and commercial. Commercial freezers are used in restaurants, water bars, food processing and supermarkets.

[0031] The basic function of the freezer is to cool down and keep the inside of the box at an appropriate low temperature. A refrigeration system generally consists of four basic components: a compressor, a condenser, a capillary or thermal expansion valve, and an evaporator. Refrigerant is a liquid that can boil at low temperature at low pressure. It absorbs heat when boiling. The refrigerant circulates continuously in the refrigeration system. The compressor increases the gas pressure of the refrigerant to cause liquefaction conditions. Wh...

Abstract

The invention relates to a freezer operation fault analysis platform and method. The platform comprises a continuous enhancement mechanism, a big data storage node, a time identification mechanism and fault recording equipment, wherein the continuous enhancement mechanism is composed of a signal input unit, a first enhancement unit, a second enhancement unit and a signal output unit. The big data storage node is used for storing an ice body brightness upper limit threshold value and an ice body brightness lower limit threshold value. The time identification mechanism is used for sending a fault instruction corresponding to an ice accumulation fault when a plurality of continuous time points are ice storage time points. The fault recording equipment is connected with the time identification mechanism and is used for storing the received fault instruction corresponding to the ice accumulation fault by adopting a built-in storage unit and sending time points of the fault instruction corresponding to the ice accumulation fault. The freezer operation fault analysis platform and method are compact in design and reliable in data; and a stable ice body in a freezer can be identified by adopting a targeted analysis mechanism, so that effective reference data are provided for subsequent fault recording and handling.

Description

technical field [0001] The invention relates to the field of failure analysis, in particular to a platform and method for analyzing the operation failure of a freezer. Background technique [0002] The study of the failure mechanism is to study the internal factors such as the physical and chemical processes that cause the failure, as well as the conditions for the occurrence and development of the failure. This is a problem that product designers need to be more concerned about. Failure mode refers to the manifestation of product failure. Failure Mode and Effect Analysis (FMEA) is mainly to analyze the form classification, performance characteristics and impact consequences of product failure states, and to understand the probability of failure and development and change rules based on experience and test results. This information is more concerned about the design and implementation of product diagnosis. Only on this basis can we determine the appropriate detection method...
