It is a kind of based on the automatically vending system weighed and methodTechnical field
The present invention relates to automatic vending machine technical field, and in particular to a kind of based on the automatically vending system weighed and sideMethod.
Background technology
Because automatic vending machine has, commodity purchasing is convenient, management is simple, floor space is small, it is artificial needed for sale to reduceThe advantages that taking, therefore just developed rapidly since its appearance, in all a large amount of popularizations in each place.
Common automatic vending machine is also relatively simple in commodity selection in the market, relates generally to bottled drink, perfume (or spice)Cigarette, the food for having independent packaging etc. calculate the automatic vending machine of commodity price in units of number, rare to sell water fruit and vegetableDish, grain etc. are to be weighed as the automatic vending machine of main identification and means of settlement, because based on the automatic vending machine weighedNeed solve more technical problems relative to non-vending machine of weighing, one of them critically important technical problem is：How to be based onWeigh and identify type of merchandize
In the prior art, patent document occurs using the automatic vending machine weighed, existing vending machine of weighingIdentification type of merchandize is realized by following two modes：
Mode one, same automatic vending machine only sell same commodity.
Mode two, same automatic vending machine have different cargo layers, same commodity are placed in each cargo layer, oftenThe corresponding weighing sensor of individual cargo layer, by the kind for judging the identification of sensor commodity that user picks up or put downClass.
Mode three, same automatic vending machine have different cargo layers, and multiple cargo layers share same weighing and sensingDevice, the species for the commodity picked up or put down is identified by setting complicated algorithm.
For mode one, it greatly limit the usage scenario of automatic vending machine.
For mode two, due to needing that a weighing sensor is separately configured for each cargo layer, considerably increase automaticVolume, manufacturing cost and the maintenance cost of vending machine.
For mode three, the calculating time is longer, algorithm design time length, and because algorithm artificially designs, vending machineThe situation faced can not possibly be to accomplish limit in algorithm for design, and BUG inevitably occurs, cause to identify when usingPrecision is not high, error is larger.
To sum up, need that a kind of simple, easily technical scheme solves based on identification type of merchandize of weighing badly in the prior artTechnical problem.
