In potato starch content automatic assay method of the present invention, in described S2 step, host computer analysis system can
With wireless real-time reception measurement result, each determination data is pressed gravimetric value in gravimetric value in air, water, Rhizoma Solani tuber osi ratio by analyzer
Weight, the order of Rhizoma Solani tuber osi dry matter content, potato starch content are uploaded to host computer successively and analyze system, and described host computer divides
Determination data can be processed, analyzes by analysis system, graph visualization shows, and by determination data and minute and sample
Numbering preserves to Excel form.Host computer is analyzed system and also can be interacted with analyzer, i.e. host computer analyzes system and survey
Determine to be formed between instrument bi-directional two-wire journey communication, directly can analyze system manipulation analyzer by host computer and work.
In potato starch content automatic assay method of the present invention, when finding that analyzer LOAD CELLS precision goes out
During existing error, calibration mode can be switched to by operation button.LOAD CELLS hangs weight tray, by the metering of standard
Counterweight is placed on weight tray, analyzer display window display gravimetric value, adjusts display numerical value by operation button and makes its value
Consistent with the weight amount of standard test weight.Also can use multistage standardizition, make system meet precision in whole range ability and want
Ask.After demarcation completes, analyzer can be switched back into the pattern of automatically determining by operation button.
The method have the advantages that

Accompanying drawing explanation
Fig. 1 is analyzer structural representation used in potato starch content automatic assay method of the present invention.
Fig. 2 is the workflow diagram of operated analyzer in potato starch content automatic assay method of the present invention.
Detailed description of the invention
Below by embodiment, potato starch content automatic assay method is described further:
Embodiment one
In this example, by time-and-motion study instrument, Rhizoma Solani tuber osi to different cultivars carries out automatization's content of starch mensuration respectively,
To investigate high efficiency and the degree of accuracy of this method.
1, start, analyzer acquiescence is in the pattern of automatically determining automatic clear, and LOAD CELLS automatically resets in being higher than
The initial position more than water surface.Select a certain amount of clean Rhizoma Solani tuber osi to be measured (1) to load the string bag and make sample 1, select a certain amount of
Clean Rhizoma Solani tuber osi to be measured (2) loads the string bag and makes sample 2.
2, hanging on LOAD CELLS by sample 1, instrument to be determined judges that, when sample is in steady statue, analyzer is i.e. remembered
Record aerial weight mg of sample 1k=17.43N, then by sample automatically by acquiescence lower travel limit drop to be totally submerged in
In water, when sample 1 is stablized in water, analyzer record sample 1 gravimetric value mg in waters=0.84N also obtains now water
Temperature, can calculate the proportion ω of sample 1 by single-chip computer control system1=1.0506, dry matter content G1=13.394%
And content of starch P1=7.624%, determination data and result are pressed gravimetric value in gravimetric value in air, water, Rhizoma Solani tuber osi ratio simultaneously
Weight, Rhizoma Solani tuber osi dry matter content, the order of potato starch content, be uploaded to host computer the most in real time and analyze system.Then survey
Determine instrument and sample is risen to automatically initial position, sample 1 has been taken off and has once measured.Mensuration process is automatically, quickly., once
Measure time-consuming about 10 seconds.
3, hanging on LOAD CELLS by sample 2, analyzer will automatically be recorded the quality in sample 2 air by said process
mgk=16.75N, sample 2 gravimetric value mg in waters=1.55N and the temperature of water, and calculated specific gravity ω2=1.102 is the most corresponding dry
Content of material G2=24.393% and content of starch P2=18.629%.The Rhizoma Solani tuber osi tool of both the above different cultivars as can be seen here
Having the difference on obvious content of starch, this result and both sample Rhizoma Solani tuber osis are in the content of starch phase one measured by laboratory
Causing, its precision can guarantee that within 1%.
Embodiment two
In this example, it is intended to illustrate when measuring stroke and being unsatisfactory for requiring, by revising and mensuration stroke can be remembered, it is achieved
The hommization of sample content of starch measures.
Described in example one performed as described above, hanging on LOAD CELLS by sample 1 after start, sample 1 is declined by analyzer automatically
To lower travel limit, but now due to water shortage or the reason such as the sample string bag is shorter in steel ladle, sample 1 is caused to fail completely
It is immersed in water, thus analyzer have recorded gravimetric value mg in inaccurate waters, content of starch meeting that now analyzer calculates
Error occurs.For this phenomenon, need mensuration stroke is modified, after sample 1 rises to initial position, pressed by operation
Button controls driven by motor sample 1 and drops to the appropriate location being totally submerged in water, and single-chip computer control system i.e. remembers this position
For new lower travel limit, automatically sample 1 is risen to initial position subsequently.The most again sample 1 is suspended on LOAD CELLS,
Analyzer will be automatically determined by the lower travel limit of new settings, obtains content of starch accurately.
Wherein, embodiment 2 is revised and remember mensuration stroke can be realized by following two method:
Method one:
Using memory LOAD CELLS extreme lower position is lower travel limit, and step is as follows:
1, LOAD CELLS acquiescence is placed in the stroke upper limit i.e. initial position x0, by the operation button row to LOAD CELLS
Journey lower position is adjusted.Make LOAD CELLS decline when pinning decline button, unclamp decline button, i.e. remember biography of weighing
Sensor position x1；Make LOAD CELLS increase when pinning rising button, unclamp rising button, i.e. remember LOAD CELLS
Place, position x2.May need that operation button is used for multiple times in practical operation just makes LOAD CELLS adjust to required new row
Journey lower position.After loosing one's grip, LOAD CELLS position is (x the most every time1, x2, x3..., xn)。
2, after each release button, whether analyzer can be stablized by automatic decision sample in water, after sample is stable, surveys
Determine instrument and automatically LOAD CELLS is risen to the stroke upper limit i.e. initial position.Single-chip computer control system memory internal lower travel limit
Num=Max (x1, x2, x3..., xn)-x0。
3, lower travel limit has been revised, and can restart to be measured according to automatic measuring process.
Method two:
Using study button-pressing way memory lower travel limit, step is as follows:
1, LOAD CELLS acquiescence is placed in the stroke upper limit i.e. initial position x0, by the operation button row to LOAD CELLS
Journey lower position is adjusted.Make LOAD CELLS decline when pinning decline button, unclamp decline button, i.e. remember biography of weighing
Sensor position x1；Make LOAD CELLS increase when pinning rising button, unclamp rising button, i.e. remember LOAD CELLS
Place, position x2.May need that operation button is used for multiple times in practical operation just makes LOAD CELLS adjust to required new row
Journey lower position.After loosing one's grip, LOAD CELLS position is (x the most every time1, x2, x3..., xn)。
2, sensor to be weighed is positioned at required new lower travel limit position xnTime, click on study button and i.e. remember under this trip
Limit, then LOAD CELLS is risen to the stroke upper limit i.e. initial position by analyzer automatically.
Single-chip computer control system memory internal lower travel limit num=xn-x0。
3, lower travel limit has been revised, and can restart to be measured according to automatic measuring process.
Wherein, LOAD CELLS position memory principle: single-chip computer control system gives tacit consent to a counting variable at initial position
Y, in LOAD CELLS process of rising or falling, y adds and subtracts accordingly, and after release button, x is carried out assignment i.e. x=y.
