Intelligent self-service retail method for liquid products based on intelligent Internet of Things

Abstract

The invention discloses an intelligent self-service retail method for liquid products based on the intelligent Internet of Things, and belongs to the technical field of liquid product selling. The method comprises the steps that 1, corresponding required liquid outlet amount information is input, and the information is transmitted to a single-chip microcomputer of a control mainboard through a touch screen Android mainboard; 2, after the single-chip microcomputer of the control mainboard receives the information, the single-chip microcomputer of the control mainboard reads monitoring data of an air pressure sensor and controls an air pump to work; 3, the air pump transmits pressure to a liquid storage barrel through a distributor, and a liquid in the liquid storage barrel is pressed out through the distributor by means of the pressure difference; 4, an electromagnetic valve is opened, the liquid flows out of a liquid outlet pipe, a flowmeter starts to work when the liquid flows out, and a pulse signal is sent out in real time according to the liquid passing amount; and 5, the pulse signal output of the flowmeter is connected with the control mainboard through a wire, the single-chip microcomputer of the control mainboard obtains the pulse signal of the flowmeter in real time and checks the pulse signal with a preset value, and when the input liquid outlet amount is reached, theliquid outlet work is finished.

Description

technical field [0001] The invention relates to the technical field of selling liquid products, and more specifically relates to an intelligent self-service retail method for liquid products based on the intelligent internet of things. Background technique [0002] The country is currently advocating low-carbon economy, energy conservation and environmental protection, to achieve sustainable economic and environmental development. At present, more and more liquid products in the market spend a lot of cost to do various pre-packaging for one-time consumption. The packaging cost is high, and these packaging often cause pollution to the environment and waste resources. With the rapid development of intelligent technology and Internet of Things technology, the basic technology to solve this problem already exists. At present, the smart vending machines, smart liquid vending machines, and red liquid dispensing machines that have appeared on the market all place the goods inside ...
