AI Technical Summary

Problems solved by technology

All these controls are difficult to complete only by manual control
The commercial display freezers produced in the past did not have the function of automatic adjustment according to the usage conditions, resulting in waste of idle time, insufficient busy time, large power consumption and failure to achieve the expected cooling effect

Embodiment Construction

[0012] Embodiments of the utility model are further described below in conjunction with the accompanying drawings:

[0013] see figure 1 , figure 2 , image 3 As shown, the present invention determines whether the control system is in a "running" state or a "standby" state by manually setting the business start and end time of the place where the commercial display refrigerator is placed.

[0014] During the "running" state, the microprocessor 1 has a real-time clock reading device. Under the "running" state, the microprocessor 1 divides the running time into several equal time segments, and the length of each time segment can be several minutes to several minutes. Hours, collect the number of times customers open the door to pick up goods in each time period, so as to judge the busyness of the freezer. The current storage address of the EEPROM memory 5 is determined according to the current date and time value, and the busyness data of each time period is continuously sto...

Abstract

The controller includes microprocessor, cabinet door, temperature sensor, EEPROM, and real-time clock chip, control program. Characters are that cabinet door, temperature sensor are connected to an input port of the microprocessor; sampled information is stored inside EEPROM; based on data setup by push key control circuit, and sampled information, control program of microprocessor gives out new modified adjust value of temperature after processing; controller possesses unit for reading and fetching real time clock; evaporation fan makes periodic intermittent working. Based on different instance and history log, the microprocessor realizes intellectualized control. Advantages are: operation of compressor controlled in optimization, saving electrical energy, and guaranteeing quality of foodstuff.

Description

Technical field: [0001] The invention relates to an intelligent energy-saving controller of a commercial display refrigerator, in particular to an intelligent energy-saving controller of a commercial display refrigerator controlled by a microprocessor. Background technique: [0002] At present, due to the fact that the customer flow in the shopping mall is constantly changing with the seasons and holidays, even in different time periods of the day, it is always in constant change. When the freezer is in the "busy" working state, it is necessary to adjust the working temperature of the freezer to be lower in order to meet the needs of customers; and when the customer flow is low and the freezer is in the "idle" working state, it is necessary to adjust the working temperature slightly. Higher, in order to save the electricity consumed by the compressor cooling as much as possible under the premise of ensuring the freshness of food. Especially when the shopping mall is closed ...
