Temperature control method, controller and temperature-adjustable express black box

Abstract

The invention relates to a temperature control method, a controller and a temperature-adjustable express black box. The temperature control method comprises the following steps: acquiring the temperature of an inner layer of a cover body; comparing the temperature with a preset temperature range; the temperature range comprising a temperature upper limit and a temperature lower limit; if the temperature of the inner layer of the cover body exceeds the temperature range, obtaining the temperature of the outer layer of the cover body and comparing the temperature of the outer layer of the cover body with the temperature range to obtain a comparison result; and starting a refrigerating device or a heating device in the cover body according to the comparison result until the temperature of the inner layer of the cover body is within the temperature range. The constant-temperature environment can be kept in the commodity transportation process, and if the set temperature is higher than the temperature outside the box and lower than the temperature inside the box, a ventilation opening is opened for ventilation to reduce the temperature; and if the set temperature is higher than the in-box temperature, the heating system is started to increase the in-box temperature. In addition, the running state, endurance time, battery life and the like of the express black box can be mastered in real time, the unqualified box bodies are recycled and maintained and put into use again, and the purpose of environmental protection is achieved.

Description

technical field [0001] The invention belongs to the technical field of express logistics, and in particular relates to a temperature control method, a controller and an express black box with adjustable temperature. Background technique [0002] With the rapid development of e-commerce, online transactions on mobile terminals have become the main means of people's transactions, which greatly facilitates people's lives. However, when buying medicine, vegetables, quick-frozen food or dairy products, the external environment temperature is too high or too low, and the items are prone to abnormal conditions due to the high or low temperature in the circulation process, causing losses to the merchants and also causing inconvenience to consumers. [0003] In related technologies, when express delivery of goods that require a constant temperature to ensure quality, the deterioration of the goods is often prevented by reducing the transportation distance, reducing heat exchange thr...
