Background

Because the vending machine occupies a small area, only a daily maintenance replenishment source is needed, a vending person is not needed, and the selection of laying places is diversified. The vending machine has more and more application scenes and more types of equipment. The automatic vending machine in the hotel guest room has the characteristics of small size and convenient vending and is favored by the market.

The existing hotel vending machine loading process is completed by manual operation, however, the hotel vending machine generally has no hardware equipment and service system for judging the commodity state, which leads to that if the loading personnel loads wrong commodities, the background can not detect the wrong commodities. The situation of goods stringing in the cabin or misplacing the goods is inevitable, which also brings bad consumption experience to the consumers. In addition, existing vending machines often fail to autonomously determine whether a customer has completed picking. This results in the door closing action being completed by the customer after the goods have been taken, which increases the chance of the interior space of the machine being open, resulting in soiling or loss of material. The automatic locking operation needs to determine whether the commodity is taken away, and the existing machine does not have the function.

The situation is common in hotel vending machines on the market, and although personnel management can be strengthened to avoid the situation as much as possible, the situation still consumes time and labor. If the vending machine has the commodity state judging and prompting functions, the commodity state can be detected, and the commodity placing error or the sold state can be self-detected. Furthermore, due to the application environment of the hotel room, in order to ensure the information security of customers, the scheme based on image and audio processing is not suitable for the environment. Without adopting the above-described solution, how the vending machine can still have the commodity state determination and presentation functions becomes a new subject.
