Description

technical field [0001] The invention relates to liquid vending technology, in particular to a metering system and control method of a liquid vending machine. Background technique [0002] At present, the liquid sold by the intelligent liquid vending terminal on the market is measured by volume, but most of them are measured by weighing. The weight transmitter receives the signal of the pressure sensor installed under the weighing pan and converts it into The weight value is uploaded to the microprocessor for data calculation according to the type and concentration of the goods sold, and then converted into capacity. [0003] However, due to temperature, humidity, installation level, and analog interference, the measurement accuracy is greatly affected. In addition, the pressure sensor used in the weighing measurement method has a maximum pressure limit. When the container is placed or taken out, it will drop or other conditions will occur. , When the pressure sensor is subj...
