However, changes such as air flow, temperature changes, and ice melting in the vending cabinet will weigh the weight of the pallet and the products on the pallet before the door is opened and the weight of the pallet and the products on the pallet after the door is closed. amount of significant interference
At the same time, the accumulation of errors caused by multiple pick-and-place products after the customer opens the door will also seriously affect the accurate weighing of the weight value of the pallet and the products on the pallet after the door is closed.
There are still obvious errors in the calculation of the weight change caused by the weight change before and after the item is picked and placed by the vending cabinet using the weighing device in the prior art

The invention provides a weighing device which is characterized in that the weighing device comprises a plurality of weighing units which are used for weighing pallets and commodities contained in the pallets so as to weigh corresponding weight values in real time; an information processing module, comprising a stable value acquisition part, a recording part, a pick-and-place judgment part, a stable value determination part and a weight change value calculation part, the stable value acquisition part acquiring a weight value weighed by the weighing unit in real time, and judging a stable weight value obtained by the weighing unit in a stable state. The recording part records stable weight values in a stable state in sequence, the pick-and-place judging part judges whether the difference value between the continuous stable weight values is larger than a preset pick-and-place judging threshold value or not, and the stable value determining part is used for setting a first weight stable value and a second weight stable value. The weight change value calculation part calculates a difference value between the second weight stable value and the first weight stable value as a weight change value generated before and after the commodity is taken and placed.
Description
technical field [0001] The invention relates to the technical field of vending cabinet weighing, in particular to a weighing device and an unmanned vending system. Background technique [0002] The vending cabinet usually uses an image recognition system or a weighing device to obtain the number of items sold when selling goods. The image recognition system generally uses images to identify the number of items on the pallet of the vending cabinet. Therefore, the vending cabinet using the image recognition system is only suitable for selling items of standard specifications, such as whole bottles of beverages, bags of food, etc., not suitable for Sell items that don't have standard specifications, such as fruit, etc. The weighing device calculates the quality of the items on the pallet, so the vending cabinet using the weighing device is not only suitable for selling items of standard specifications, but also suitable for selling items without standard specifications.
