Embodiment

Please refer to Fig. 1, it is the system block diagram according to the system of the estimating dynamic stock of one embodiment of the invention.In the present embodiment, the system 10 of estimating dynamic stock comprises an accommodating chamber 100, is arranged at electronic label identification device 110 and Weight-measuring device 120 in the accommodating chamber 100, and calculation element 130.Moreover, put into and preferably can have the electronic tag 142 and 152 that can be discerned by electronic label identification device 110 on the article 140 and 150 of accommodating chamber 100 separately.Certainly, do not have electronic tag if put on the article of accommodating chamber 100, as article 160, or the electronic tag on the article can't discern, and then these article classified as a kind of particular category.In addition, when reality enforcement is of the present invention, might not need the existence of accommodating chamber 100, that is accommodating chamber 100 can be closed space or open space.Perhaps, in other words, article can only need be placed with Weight-measuring device 120 by system of the present invention, and read the incidental electronic tag of the article that are positioned on the Weight-measuring device 120 with electronic label identification device 110, and relevant information provided to calculation element 130 get final product.

In the present embodiment, Weight-measuring device 120 has carried the article of depositing in accommodating chamber 100 the insides, and measures the overall weight of all these article.130 of calculation elements are connected to Weight-measuring device 120 and electronic label identification device 110, it receives aforesaid overall weight, and discern the result of the electronic tag gained on the interior article of accommodating chamber 100 according to placing the overall weight that obtained respectively before and after a certain article and electronic label identification device 110, estimate and write down the storage of these article.

Though must be noted that Weight-measuring device 120 herein is that the present invention is not only can be as unique embodiment in order to the weight of measurement article.For instance, also can apply in the native system in order to the device for pressure measurement of gaging pressure, and the weight that obtains article by the force value that measures and correlation parameter.And, in follow-up instructions, will all represent the various devices that can correctly obtain Item Weight with Weight-measuring device for the convenience on telling about.

For correctly estimating the weight of each article, a suitable evaluation method just must be arranged.Please refer to Fig. 2, it is the process flow diagram according to the method for the estimating dynamic stock of one embodiment of the invention.In the present embodiment, if before carrying out above-mentioned these methods, locate to exist one or more article, then before carrying out above-mentioned these methods, should know present type of goods and overall weight earlier in specific location at ad-hoc location (accommodating chamber 100 as shown in Figure 1).In order to reach this purpose, at first utilize various pick-up units (electronic label identification device for example shown in Figure 1, or the two-dimensional bar recognition device etc.) detect the kind that is positioned over the article in the accommodating chamber, and detected result is listed as into a list of articles (step S200).Wherein, if the article that pick-up unit can't identification are arranged, then all classify as a certain particular category.Moreover, the aforementioned detected device that is applicable to various pick-up units respectively, for example: radio-frequency discriminating element (RFID) and two-dimensional bar list etc. must record the title of above-mentioned these article at least.In addition, if need more accurate weight estimation, then be preferably in the packed weight of further putting down in writing above-mentioned these article on these detected devices; If not record, then the packed weight with above-mentioned these article is considered as zero.

It should be noted that abovementioned steps S200 only needs to have stored before method is carried out under the situation of article and uses, if there is no any article in accommodating chamber before method begins to carry out, then step S200 can only list the list of articles of a blank.Moreover, though in whole part instructions be for the purpose of simplifying the description with electronic label identification device and electronic tag come respectively to substitute the pick-up unit and the corresponding detected article that might use, this is not to represent the present invention only can be as unique enforcement means.

After the existing article in confirming accommodating chamber, whether the overall weight that system can begin to detect each article summation in the accommodating chamber changes (step S210) to some extent.Change to some extent in case detect overall weight, check at first then whether electronic tag has phenomenon (step S220) newly-increased or that reduce.If the electronic tag in accommodating chamber has the phenomenon of increase, there are new article to be placed in the accommodating chamber with regard to expression, can utilize the content that reads electronic tag to list newly-increased article in list of articles this moment, and the weight (or being called storage) of article is estimated (step S230).Conversely, if the electronic tag in accommodating chamber has the phenomenon of minimizing, just expression has article to be taken out from accommodating chamber, and can find corresponding article this moment according to the electronic tag that disappears, and these article are removed (step S240) in list of articles.In another case, if the article overall weight changes to some extent and the quantity that can not detect electronic tag changes to some extent, then expression article newly-increased or that take out are the aforementioned article that classify as particular category, just must revise the corresponding storage (step S250) of the article of particular category this moment.

Below will further describe previous embodiment different article insert or the taking-up situation under mode of operation.In general, article are inserted or taken out nothing more than being divided into following several: 1. put into one by one, 2. take out one by one, 3. many article are put into together, and more than 4. article take out together.Below will be introduced one by one.

When article are when putting into accommodating chamber one by one, the overall weight that can directly obtain all article in the forward and backward system of this article imbedding system is changed to T, in addition, and can learn the kind of inserting thing (or claiming the name of an article or identification code) and packed weight p by the content that reads the electronic tag on the article _iJust can simply estimate the storage R of these article thus according to following formula _i, and newly-increased or modification list of articles, file with the article that will newly insert.

R _i＝T-p _i

And when two above article were placed into native system in a flash together, the overall weight of inserting thing can only be measured by system, can't learn indivedual storages.If but there is the original net weight information of article in the electronic tag, then can estimate the scope that the indivedual storages of each article, be described as follows:

When k article are placed into native system in a flash together, suppose that each article packing weight is p _i(1≤i≤k), the original net weight of each article is N _i(l≤i≤k), inserting back entire system weight change is T, then can estimate each article storage scope R by following formula _i(1≤i≤k):

$\max (0,T-\underset{j=1}{\overset{k}{\mathrm{\Σ}}}{P}_j-\underset{j=1,j\≠1}{\overset{k}{\mathrm{\Σ}}}{N}_j)\≤R_i\≤\min (N_i,T-\underset{j=1}{\overset{k}{\mathrm{\Σ}}}{P}_j)$

And in this k article, having single or multiple article to be removed, the storage scope that then remains article can dynamically change.If take out in k article thus m article (1≤m≤k) in order to represent conveniently, and is without loss of generality, the Item Number of suppose taking-up be the 1st individual to m, overall weight minimizing T ', the storage scope R of each article in the remaining k-m article in the system _i(m+1≤i≤k) available following formula is tried to achieve:

$\max (0,T-T^{\′}-\underset{j=m+1}{\overset{k}{\mathrm{\Σ}}}{P}_j-\underset{j=m+1,j\≠1}{\overset{k}{\mathrm{\Σ}}}{N}_j)\≤R_i\≤\min (N_i,T-T^{\′}-\underset{j=m+1}{\overset{k}{\mathrm{\Σ}}}{P}_j)$

Moreover if in this k article, k-1 article before taking out when just only being left k article, are special cases, can clearly learn the article storage, needn't estimate scope.Just work as m=k-1 and i=k, but the following formula abbreviation is:

$\max (0,T-T^{\′}-\underset{j=(k-1)+1}{\overset{k}{\mathrm{\Σ}}}{P}_J-\underset{j=(k-1)+1,j\≠k}{\overset{k}{\mathrm{\Σ}}}{N}_j)\≤R_k\≤\min (N_i,T-T^{\′}-\underset{j=(k-1)+1}{\overset{k}{\mathrm{\Σ}}}{P}_j)$

$\max (0,T-T^{\′}-\underset{j=k}{\overset{k}{\mathrm{\Σ}}}{P}_j-\underset{j=k,j\≠k}{\overset{k}{\mathrm{\Σ}}}{N}_j)\≤R_k\≤\min (N_{i,}T-T^{\′}-\underset{j=k}{\overset{k}{\mathrm{\Σ}}}{P}_j)$

Wherein $\underset{j=k,j\≠k}{\overset{k}{\mathrm{\Σ}}}{N}_j=0$

max(0，T-T′-P _k)≤R _k≤min(N _k，T-T′-P _k)

T-T '-P wherein _k〉=0, N _k〉=T-T '-P _kSo, T-T '-P _k≤ R _k≤ T-T '-P _kCan draw R _k=T-T '-P _k

In addition, the article that can't discern for the electronic label identification device (comprise and do not have the article that electronic tag or its label can't be discerned for the electronic label identification device) can use one to write down to keep the entire system weight consistency especially in calculation element.When the article imbedding system, weight or device for pressure measurement are measured entire system weight and are changed, and do not change but the electronic label identification device induces electronic labeling information, then are considered as the article that can't discern.These type of article that can't discern are considered as article to calculation element with all, a given particular category (special the name of an article or identification code), and the weight summation of these type of article is considered as the article storage of article.When the one or more article that can't discern were taken out by system, calculation element upgraded the weight information of these article according to the entire system weight change.Use this technology can avoid and to cause the weight miscount by identify objects, also the article that contain electronic tag and do not contain electronic tag with existence in a flash in the tolerable system.

For the technology that makes the present invention can become apparent, below utilize real figure to enumerate a detailed example.With the intelligent refrigerator is example, wherein uses refrigerator as accommodating chamber, and the RFID label is as electronic tag, and the RFID recognition device is as the electronic label identification device, and electronic weighbridge is as weight or pressure-sensing device, and embedded system is as calculation element.

Embedded system is upgraded the information of article overall weight in the intelligent refrigerator and electronic tag at any time, that is list of articles.For example: when accommodating chamber contained half bottle of milk, a piece of beef, list of articles theed contents are as follows shown in the table:

The name of an article or identification code	Packing is heavy	Storage
			Milk	20g	?520g

Beef	50g	?295g
			Overall weight	885g

The article overall weight alleviates in the accommodating chamber when electronic weighbridge measures, and starts the RFID recognition device, only detects the RFID label of beef, the contrast list of articles, learn that milk is removed, then embedded system can be deleted the record of milk in list of articles, and the result is as shown in the table:

The name of an article or identification code	Packing is heavy	Storage
			Beef	50g	?295g
Overall weight	345g

The article overall weight increases in the accommodating chamber when electronic weighbridge measures, and starts the RFID recognition device, detects the RFID label of milk and beef respectively, and the contrast list of articles learns that milk is placed into.The accommodating chamber overall weight was 345g before electronic weighbridge was measured milk and inserted, and inserted the back for 695g, and record milk pack weight is 20g on the RFID label.According to formula R _i=T-P _iCan calculate the present storage of milk and be (695g-345g)-20g=330g, embedded system is upgraded list of articles according to above-mentioned evaluation method and is theed contents are as follows:

The name of an article or identification code	Packing is heavy	Storage
			Milk	20g	?330g
Beef	50g	?295g
			Overall weight	695g

As shown in the table, when three bottles of beverages that do not contain RFID label, gross weight 100g are inserted in the intelligent refrigerator, embedded system produces the record of product " can't discern " by name, and packed weight is set at 0g, and storage is that the accommodating chamber overall weight before and after article are inserted changes.

The name of an article or identification code	Packing is heavy	Storage
			Milk	20g	?330g
Beef	50g	?295g
			Can't discern	0g	?100g

Overall weight

795g

As shown in the table, when two bottles of beverages that do not contain RFID label, gross weight 80g wherein with taking out by accommodating chamber in a flash, embedded system is according to the variation of article overall weight in the accommodating chamber, upgrade the article record of product " can't discern " by name, packed weight is made as 0g, storage is that present storage deducts before and after article insert, and the overall weight of article changes in the accommodating chamber.

The name of an article or identification code	Packing is heavy	Storage
			Milk	20g	?330g
Beef	50g	?295g
			Can't discern	0g	?20g
Overall weight	715g

In addition, in order to solve with the problem of inserting a plurality of article in a flash, the RFID label must write down the original net weight of article except the name of an article (or identification code) and packed weight.Hold example, when three kinds of article such as cabbage, water spinach and green onion were inserted intelligent refrigerator in a flash together, electronic weighbridge was measured overall weight and is changed to 1285g-695g=590g, and just the storage of three kinds of article and packing summation are 590g.As following table, deduct the packed weight sum total 20g+15g+5g=40g of three kinds of article, learn that three kinds of article storage summations are 550g, but can't learn indivedual storages of three kinds of article.

The name of an article or identification code	Packing is heavy	Storage	Original net weight
				Milk	20g	?330g	?500g
Beef	50g	?295g	?320g
				Cabbage	20g	?550g	?300g
Water spinach	15g	?250g
			Green onion	5g	?120g
Overall weight	1285g

Can utilize aforesaid formula to estimate three kinds of article storage scope: max (0,590-(20+15+5)-(250+120))≤cabbage storage≤min (300,590-(20+15+5)) max (0,180)≤cabbage storage≤min (300,550) this moment

180≤cabbage storage≤300

Following formula estimates the cabbage storage between 180 grams restrain to 300.

Max (0,590-(20+15+5)-(300+120))≤water spinach storage≤min (250,590-(20+15+5))

Max (0,130)≤water spinach storage≤min (250,550)

130≤water spinach storage≤250

Following formula estimates the water spinach storage between 130 grams restrain to 250.

Max (0,590-(20+15+5)-(300+250))≤green onion storage≤min (120,590-(20+15+5))

Max (0,0)≤green onion storage≤min (120,550)

0≤green onion storage≤120

Following formula estimates the storage of green onion between 0 gram restrains to 120.

Through the estimation of storage scope, the list of articles that embedded system write down thes contents are as follows shown in the table:

The name of an article or identification code	Packing is heavy	Storage	Original net weight
				Milk	20g	?330g	?500g
Beef	50g	?295g	?320g
				Cabbage	20g	?180～300g	?300g
Water spinach	15g	?130～250g	?250g
				Green onion	5g	?0～120g	?120g
Overall weight	1285g

Hold, when three kinds of article are removed two kinds, can clearly calculate residue article storage.As following table, if with taking out cabbage and water spinach in a flash, when just only being left green onion in the system, the remaining 775g of article overall weight in the accommodating chamber.

The name of an article or identification code	Packing is heavy	Storage	Original net weight
				Milk	20g	?330g	?500g
Beef	50g	?295g	?320g
				Green onion	5g	Unknown	?120g
Overall weight	775g

The storage that draws green onion according to above-mentioned formula is T-T '-P _k=590-(1285-775)-5=75 such as following table:

The name of an article or identification code	Packing is heavy	Storage	Original net weight
				Milk	20g	?330g	?500g
Beef	50g	?295g	?320g
				Green onion	5g	?75g	?120g
Overall weight	775g

In sum, utilize system and method provided by the present invention, can effectively estimate the dynamic stock of various article.Moreover, when electronic tag can provide some customizing messages, even there are a plurality of article also can be estimated possible storage scope in the accommodating chamber with being placed in a flash.
