Temperature control method and system of movable smart refrigerator box {temperature control method and system of movable type smart refrigerator box}

The present invention relates to a method and system for controlling the temperature of a mobile smart refrigeration box, and more particularly, to a method and system for controlling the temperature of a mobile smart refrigeration box with improved power efficiency.

In general, as the Internet is widespread, product sellers have built an online virtual market called an online shopping mall, and Internet users can also purchase products through the virtual market without directly visiting an agency that sells specific products or goods they want to purchase. became possible

Here, such online shopping is to search for and order a product using computer communication such as the Internet or PC communication, and a user searches for a product list through the online shopping menu of a company operating an Internet shopping mall, and then selects the desired product online. If you order directly from the store and pay with a credit card or electronic money, you can enjoy convenient shopping where the ordered product is delivered to your home.

The online shopping market continues to increase due to the development of information and communication technology, the spread of the Internet, and its convenience, and further explosively increases due to the spread of mobile Internet devices such as smartphones and tablet computers.

In addition, with the advent of online shopping malls, it is possible to reduce time and costs resulting from direct purchases such as direct visits or reservation purchases by users. And, due to the advantages of such an online shopping mall, many users have used the online shopping mall, and various online shopping malls have appeared. It is operated in the form of direct sales of products to buyers by requiring information to be registered.

In particular, in the prior art, in an Internet shopping system using a mobile communication terminal to provide an online shopping mall service, a shopping server providing an Internet shopping mall, and a shopping server connected to the shopping server through the Internet to receive shopping mall related product information, A user computer that displays various products and specific purchased products and generates a shopping image corresponding to purchased product information, a mobile communication terminal that extracts the shopping image and stores it as a shopping image for a terminal, and makes a mobile payment Internet shopping systems and methods configured to receive and process payments thereto are disclosed.

On the other hand, due to the rapid increase in online shopping, Internet shopping, or TV home shopping as described above, the delivery service is becoming a universal means of connecting shopping malls and customers. On the other hand, the delivery service is a human logistics service that is ultimately serviced by the direct movement of the delivery driver. Therefore, if it is impossible to continuously increase the number of couriers in proportion to the increasing amount of parcels, increasing the amount that one courier can deliver at a set time by streamlining the movement of the courier itself is the most realistic way to handle the increasing amount of parcels. becomes a solution.

And, in the case of delivery of fresh food, it is required to maintain freshness from the transportation process to delivery of the fresh food to customers. Moreover, even when fresh food arrives at the delivery destination, but the customer cannot immediately receive the fresh food due to unavoidable circumstances, the maintenance of freshness is required.

However, in the prior art, when a delivery box equipped with a refrigeration device is used to maintain the temperature of fresh food, the refrigeration device is manually driven and stopped, and power is used inefficiently even when the amount of available power is limited, resulting in reduced power efficiency and reduced power efficiency. There was a problem in that the operating time of the device was shortened.
