Problems solved by technology

[0003] However, in the actual application process, if the user bumps the weighing module, or the user releases the product at a higher position, due to the acceleration of the free fall of the product, the force felt by the gravity sensor module will Increase, using the weight value at this time as the actual weight value of the product will lead to an increase in the weight of the product, resulting in an increase in the quantity of the product, which will cause the calculated quantity of the product to be inconsistent with the actual quantity of the product

Embodiment Construction

[0062] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, but not to limit the present invention. In addition, it should be noted that, for the convenience of description, only some structures related to the present invention are shown in the drawings but not all structures.

[0063] figure 1 It is a schematic flow chart of a weighing method provided by an embodiment of the present invention. refer to figure 1 , the weighing method includes:

[0064] S11. The weighing module acquires the weight value of the commodity placed on the weighing module in real time, and transmits the acquired current weight value to the data processing module at a preset frequency per unit time.

[0065] Wherein, the weighing module can be a bellows weighing module, a cantilever arm weighing module or a co...

Abstract

The invention discloses a weighing method, a weighing device, an unmanned vending cabinet and an unmanned vending method. The weighing method includes: the weighing module obtains the weight value of the commodity placed on the weighing module in real time, and transmits the obtained current weight value to the data processing module according to the preset frequency per unit time; the data processing module according to the preset Multiple current weight values ​​received within a time period to obtain the current actual weight value of the product on the weighing module. The technical solution provided by the present invention increases the frequency at which the weighing module transmits the current weight value to the data processing module per unit time, and obtains the current actual weight of the product through the data processing module screening multiple current weight values ​​within a preset time period Value, can more accurately obtain the current actual weight of the product on the weighing module, reduce the probability that the actual weight of the product does not match the weight obtained by the test, thereby reducing the probability that the calculated quantity of the product does not match the actual quantity of the product.

Description

technical field [0001] The embodiment of the present invention relates to the technical field of automation equipment, in particular to a weighing method, a weighing device, an unmanned vending cabinet and an unmanned vending method. Background technique [0002] With the popularity of the new retail unmanned vending business model in the market, the current new retail sales model is mainly realized by image recognition and weighing. At present, the weighing method usually adopts a gravity sensing module (also called a gravity module) for weighing, and an open shelf is used. The basic principle is: put the same type of goods on the same gravity module, and the weight of each product is the same. When the weight changes, the number of items taken by the user can be obtained by dividing the weight change by the weight of a single item. [0003] However, in the actual application process, if the user bumps the weighing module, or the user releases the product at a higher posi...
