Constant-temperature express cabinet and constant-temperature control method

Abstract

The invention discloses a constant-temperature express cabinet and a constant-temperature control method. According to the constant-temperature express cabinet, the temperature in the storage cabinetis detected by a temperature sensor. A refrigeration system, a heating device and a ventilation system are controlled to operate by an industrial personal computer according to the temperature, so that the constant-temperature environment of the express cabinet is guaranteed all the time. Therefore, by adopting the constant-temperature express cabinet and the constant-temperature control method, the abnormity of articles in the storage cabinet due to the ambient temperature can be effectively prevented, additionally, electronic components in the express cabinet are protected, the service lifeof the express cabinet is prolonged, the use reliability of the express cabinet is increased, and the late maintenance cost is reduced.

Description

technical field [0001] The invention relates to the technical field of automation control, in particular to a constant temperature express cabinet and a constant temperature control method. Background technique [0002] With the rapid development of e-commerce and frequent online transactions, consumers' demand for sending and receiving mail has increased dramatically. In order to cope with the growth of the express delivery business, express cabinets are now installed in some residential areas.

AI Technical Summary

Problems solved by technology

The traditional express cabinet is just a cabinet for holding items, and there is no setting inside. The air circulation in each cabinet of the express cabinet is not smooth, and the heat or temperature distribution is uneven.

When the external ambient temperature is too high or too low, the items in the cabinet are prone to abnormal conditions due to the temperature being too high or too low

Moreover, if the temperature is too high or too low, it will also cause certain damage to the express cabinet. In the state of high temperature and low temperature for a long time, the express cabinet will be easily damaged and its service life will be shortened.
