Technical field
Weighing is accessed the present invention relates to kinds of goods and counts technical field, and what specially a kind of kinds of goods access weighing counted goes automatically
Skin method.
Background technique
The counting to kinds of goods is realized using weighing technology, this method is because of identical kinds of goods individual character weight differential or weighing and sensing
Device reason will lead to miscount, and concrete reason generally has following several:
One, by weight calculation kinds of goods itself
It is counted the range of typically just a approval of kinds of goods weight, it is impossible to completely the same.These same size kinds of goods
Weight difference can generate accumulation, and final item quantity is caused to calculate mistake.
Two, sensor reason
Weighing sensor may generate permanent or semipermanent mechanical deformation (creep) due to bearing a heavy burden for a long time and can generate
Weight drift；Environmental change all will lead to metering of the weighing sensor to weight if temperature, humidity change.
Sensor is within a short period of time, as smaller in metering variation occurs in several hours, generally permits what weighing counted
Perhaps in range；And this variable quantity will be bigger for a long time, the especially counting process to small quality kinds of goods (within such as 5 grams)
In, it will result in the erroneous judgement to quantity, this is not can avoid since the working principle of sensor itself determines.
Weight difference between same specification kinds of goods certainly exists, and even complete qualified products are also only for weight
Allowed band.The tolerance of these kinds of goods counts and will be not allowed for will not influence counting when negligible amounts, but after accumulating, in fact
It is also unavoidable.
To sum up, any weighing inductor no matter do it is much accurate all inevitably there is a weight drifting problem, count
Temperature, temperature, the long-time pressure of weight at that time can all interfere weighing results, if pressing [inventory=total weight/goods and materials substance]
Carry out number of computations, weight change centainly will lead to quantity variation, if weight change be it is certain, quantity is bound to not
It is quasi-.In actual test, then this drift value time of good weight calculation inductor, grown all can be very big, but time not long variation is very
It is small.To solve this problem, it is contemplated that " peeling " function of electronic scale, provide a kind of kinds of goods access weighing count it is automatic
Barking method.
Summary of the invention
In view of the deficiencies of the prior art, the present invention provides a kind of kinds of goods to access the automatic peeling method that weighing counts, purport
Existing weighing counting equipment is unavoidable slowly to generate error solving, compartment time or access will go after several kinds of goods compared with
The problem of quasi- weighing-appliance.
To achieve the above object, the invention provides the following technical scheme: the automatic peeling that a kind of access weighing of kinds of goods counts
Method, which comprises the following steps:
S01. it when kinds of goods there is any discrepancy library operates, obtains gross weight before operating and simultaneously calculates tare weight, gross weight-before tare weight=operation
Inventory * goods and materials substance before operating；
S02. gross weight after operating, inventory after calculating operation, after operation are obtained again after going out to be put in storage varied number operation
Inventory=(gross weight-tare weight after operation)/goods and materials substance.
Preferably, in the step S01, gross weight and tare weight obtain before operationies on incoming and outgoing inventory will occur before operating.It can lead to
The switch sensor for crossing library door can determine whether that operationies on incoming and outgoing inventory can occur, tare weight first calculated before operationies on incoming and outgoing inventory, is had
Power saving, energy-efficient effect.
Preferably, since the variation of weighing sensor is that slowly, in the step S01, gross weight and tare weight exist before operating
It periodically obtains once, and is saved to database or program internal memory, for being used when operationies on incoming and outgoing inventory when library operation that there is any discrepancy.Periodically
Can be 1 hour for interval, to realize that automatic tare weight updates, improve the timeliness that inventory is calculated with warehousing quantity out after operating.
Preferably, some cabinets can also show warehousing quantity, since tare weight is that positive and negative values are likely to；Therefore, it also wraps
Following steps are included, warehousing quantity is calculated, several ∣ are deposited in the preceding library of inventory-operation after warehousing quantity=∣ operation out.
Preferably, the gross weight includes weighing-appliance gross weight, such as the weight of weighing-appliance tray.
Beneficial effects of the present invention: by software algorithm means, it is not allowed to ask to solve to cause because of objective reality reason to count
Topic realizes that weighing counting equipment is run steadily in the long term, realizes that weighing counts accurate for a long time.
Specific embodiment
Embodiment 1
A kind of automatic peeling method that kinds of goods access weighing counts, comprising the following steps:
S01. it when kinds of goods there is any discrepancy library operates, is spaced gross weight before acquisition once-through operation in 1 hour and calculates tare weight, and protect
It deposits to database or program internal memory, for being used when operationies on incoming and outgoing inventory, wherein inventory * object before gross weight-operation before tare weight=operation
Provide substance；It realizes that automatic tare weight updates, improves the timeliness of inventory and the calculating of warehousing quantity out after operation；
S02. gross weight after operating, inventory after calculating operation, after operation are obtained again after going out to be put in storage varied number operation
Inventory=(gross weight-tare weight after operation)/goods and materials substance；And inventory return step SO1 after operating；It can also calculate
Warehousing quantity is calculated, several ∣ are deposited in the preceding library of inventory-operation after warehousing quantity=∣ operation out.
It repeats the above steps, the accurate acquisition of inventory after operation in real time is realized with this, not by equipment and environmental change
Influence.
About embodiment 1
Known total weight=goods and materials substance * stockpile number.Do not go out in goods yard, in-stockroom operation when, background system interval 1 is small
Shi Yizhi is doing tare weight acquisition operation.Specific algorithm improve it is as follows, here more than tare weight value, the [weighing-object of tare weight=instantly
Provide stockpile number * goods and materials substance]
Practical micro- warehouse true algorithm of varied number when receiving or storing is as follows: gross weight-operation before tare weight=operation
Preceding inventory * goods and materials substance；
It is assumed that obtaining storage item quantity on current goods yard A01 in database or program internal memory is 10, and kinds of goods list
Weight be 100 (note: the weight being referred to herein be not actual weight such as gram, kilogram or ton, but cargo is placed in weighing and sensing
The AD value converted after on device by AD stamen piece [digital-to-analogue conversion])；
Gross weight before operating (including kinds of goods and storage kinds of goods container) is obtained from weighing sensor, is such as obtained and is weighed as instantly
1500；
Calculate tare weight, inventory * goods and materials substance before gross weight-operation before tare weight=operation；That is tare weight=(1500-10*100)
=500；
500 are saved to database or program internal memory, for using when operationies on incoming and outgoing inventory；
When operationies on incoming and outgoing inventory occur, the calculation method of inventory is changed to after operation: inventory after operation=(total after operation
Weight-tare weight)/goods and materials substance；It is assumed that gross weight is 1300 after operation when weighing again, then inventory=(1300- after operation
500)/100=8, i.e., it is 8 remaining, then warehousing quantity=∣=2 ∣ 10-8 out.
After a period of time, due to weighing sensor, 1300 are changed to 1400, i.e. tare weight has added 100, pass through the method
Calculating tare weight at this time is 1400-8*100=600, also increases 100 tare weight, is not influenced by equipment and environmental change.
Benefit with this automatic peeling algorithm is by objective reality defect such as kinds of goods tolerance, weighing and sensing because of temperature, wet
The weight drift value that degree variation or permanent load generate all is concluded into goods yard tare weight, away from going automatically when because of kinds of goods operationies on incoming and outgoing inventory
The skin operating time is shorter, and tare weight is about current tare weight, overcomes these irresistible weight changes, enables intelligent commodity shelf
Operation steady in a long-term.
The foregoing is merely illustrative of the preferred embodiments of the present invention, is not intended to limit the invention, all in essence of the invention
Made any modification, equivalent replacement or improvement etc., should all be included in the protection scope of the present invention within mind and principle.
