Method.
Background technique
Self-service cabinet is the inevitable outcome of retail business development, is more and more promoted, but nothing currently on the market
People's sales counter all without automatically detect kinds of goods function, system can not automatic identification consumer what kinds of goods taken, taken more
Few kinds of goods need consumer voluntarily to settle accounts manually to be unable to Automatic-settlement, and this shopping process influences the pleasure of consumption experience
Degree influences efficiency of doing shopping, and the elderly for having little understanding to smart machine, has operating barrier, be equivalent to and in a disguised form refuse
The consumption of some consumers groups, popularization degree absolutely is restricted.
Weighing is to utilize Hooke's law or the lever balance theory of power measurement mass of object.Existing band weight induction
The self-service cabinet of system has the following problems: 1. weight induction formula self-service cabinets on non-level face in use, due to
The pressure direction and support that multiple support legs (generally 4) of counter cause kinds of goods to apply tray not in a horizontal plane
Pressure sensor standard Impact direction is inconsistent on foot, this will result in, and test weight is partially light, and the two deviation angle is bigger, measurement
Error is also bigger.2. the tray weighing measurement principle of weight induction formula self-service cabinet is applied to using weighing sensor measurement
Tray Vertical Square upwards pressure, and the standard quality unit of kinds of goods (m) is kilogram (kg), and the unit for the power (F) that tray measures
It is newton (N), is converted between the two by the local gravity acceleration g of measurement:
F=m*g
Due to the gravity acceleration g of different location on the earth be it is different, so same weight induction formula nobody sell
Counter measures the object of same quality in different regions, and obtained pressure F is different.But it for convenience's sake, reduces and surveys
Cost is measured, gravity acceleration g is all normalized into 9.8 to calculate all over the world, this just brings biggish error to measurement.
