The invention provides a commodity quantity detection device and method and a vending machine. The device comprises a commodity tray, a processor and at least one infrared distance measurement module.The commodity tray is obliquely arranged relative to the horizontal plane, so that commodities arranged on the commodity tray in rows can slide towards the lower first ends of the commodity trays under the action of gravity. The at least one infrared distance measurement module is arranged at a higher second end of the commodity tray. Each infrared distance measurement module is used for emittinginfrared light towards the first end of the commodity tray along the direction of one commodity column, receiving the reflected infrared light, generating a corresponding level signal according to the time difference between the emission of the infrared light and the reception of the infrared light, and sending the level signal to the processor. The processor is used for determining the number ofremaining commodities in the commodity column, corresponding to the infrared distance measurement module, on the commodity tray according to the level signal sent by the infrared distance measurementmodule for each infrared distance measurement module. According to the scheme, the cost for detecting the number of commodities in the vending machine can be reduced.
Description
technical field [0001] The invention relates to the technical field of automatic vending, in particular to a commodity quantity detection device, method and automatic vending machine. Background technique [0002] A vending machine is a machine that can automatically pay for goods after the user pays, and is a common equipment for commercial automation. Vending machines can not only make the sale of goods not limited by time and place, but also save manpower, thus making commodity transactions more convenient. Since the vending machine is an unattended device, the vending machine needs to detect the quantity of remaining goods in it, so as to notify the replenishment personnel in time to replenish the goods when the remaining goods are insufficient. [0003] At present, in order to detect the quantity of goods in the vending machine, a radio frequency tag is set on each commodity in the vending machine, and the vending machine determines the quantity of remaining goods in i...
