Embodiment one:
Liquid beverage can be other drinks such as white wine, beer, red wine, and this example take liquid beverage as red wine is example, utilizes the said method identification red wine true and false to be measured, and its testing process is as follows, and process flow diagram as shown in Figure 2.
S201: gather: immersed by pick-up unit in red wine to be measured, gathers red wine characteristic.
Red wine to be measured is also without the red wine of the process of sobering up, and the amount of taking fully red wine to be measured, is placed in red wine to be measured by pick-up unit, and the switch of opening detecting device, pick-up unit starts recognition detection automatically.
What is called is sobered up, refer to the open hour of red wine by injection device for sobering drunken people, wine liquid bump contact air can be made, thus acceleration tannic acid softens, fully discharges closed fragrance, the i.e. process of red wine oxidation, so red wine to be measured must be the oxygen in the not contacted air in just Kaifeng.
Liquid beverage characteristic comprises electrical characteristics, the attribute that electrical characteristics show under the current excitation of different frequency, different wave and different amplitude for testing liquid drink, concrete to gather red wine electrical characteristics, the detailed process gathering red wine electrical characteristics comprises the steps, its process flow diagram as shown in Figure 3:
S2011: the exciting electrode of pick-up unit sends pumping signal to red wine to be measured;
S2012: the signal detection electrode of pick-up unit gathers the electric signal that red wine to be measured responds pumping signal;
S2013: transform electrical signals is electrical characteristics by the processing module of pick-up unit.
S202: extract record: pick-up unit extracts at interval of preset time period and records red wine characteristic, until red wine characteristics held constant value.
The step that pick-up unit extracts red wine characteristic is as follows, its process flow diagram as shown in Figure 4:
S2021: the exciting electrode of pick-up unit sends pumping signal at interval of preset time period to red wine to be measured;
S2022: the signal detection electrode of pick-up unit gathers the electric signal that red wine to be measured responds pumping signal;
S2023: transform electrical signals is electrical characteristics by the processing module of pick-up unit;
S2024: pick-up unit extracts and records electrical characteristics;
S2025: judge whether the electrical characteristics recording N time are continuously same numerical value, and N>1, if not same numerical value, then returns S21 step, and same numerical value performs S3 step in this way.
Such as, preset time period is 1min, when N is 3, the exciting electrode of pick-up unit sends pumping signal to red wine to be measured automatically again every 1min, and record the electrical characteristics that each pumping signal produces in red wine to be measured, if the electrical characteristics of continuous 3 records are same numerical value, then the exciting electrode of pick-up unit stops sending pumping signal to red wine to be measured, otherwise continue interval 1min and send pumping signal to red wine to be measured, until occur that the electrical characteristics of continuous 3 records do not change.
S203: calculate: pick-up unit draws red wine family curve according to the red wine characteristic of record, and calculates red wine eigenwert.
The red wine characteristic that pick-up unit records in S202 step is electrical characteristics, as admittance, specific inductive capacity etc., the processing module of pick-up unit draws the red wine family curve of red wine to be measured in oxidizing process by analyzing electrical characteristics, and calculating red wine eigenwert by red wine family curve, red wine eigenwert is the characteristic slope of red wine, tangent slope, flex point and is worth most.
S204: matching identification: the eigenwert of red wine eigenwert and standard database contrasted, according to the comparing result identification red wine true and false to be measured.
Standard database is the database storing multiple brand red wine eigenwert established, and the eigenwert in standard database is extracted under room temperature 25 degree, if pick-up unit is not at room temperature detect red wine to be measured, then pick-up unit also comprises and revising red wine eigenwert, and then the eigenwert in revised red wine eigenwert and standard database is contrasted, as revised by temperature compensation, the true and false of the recognition methods of this example to red wine is made to distinguish that applicability is strong, as, can in different occasion, temperature can both carry out red wine truth identification, be not subject to the impact of region and red wine product.
