Being further used as preferred embodiment, whether described ESL server real-time judge receives POS server pushesPricing information message or the exchange rate message of exchange rate server push, the most then and then generate corresponding explicit message and be pushed toThe step of the corresponding ESL of corresponding goods, itself particularly as follows:
Whether ESL server real-time judge receives pricing information message or the exchange rate server push that POS server pushesExchange rate message, the most then when receiving the pricing information message that POS server pushes, according to pricing information message and this localityAfter the exchange rate data table of storage calculates the Multiple Currencies commodity price of corresponding goods, traveling through ESL, it is right to generate for each ESLThe explicit message answered, and push explicit message with asynchronous message form to each ESL；Or receiving exchange rate server pushThe exchange rate message time, update locally stored exchange rate data table according to exchange rate message, and update the Multiple Currencies calculating corresponding goodsAfter commodity price, after traveling through ESL, it is thus achieved that the corresponding all ESL of these commodity, and then each ESL generation for obtaining is rightThe explicit message answered, and push explicit message with asynchronous message form to each ESL.
Concrete, as it is shown on figure 3, ESL server is through the following steps that calculate the Multiple Currencies price of commodity:
Read the home currency Currency Code Uc of exchange rate data table；
It is successively read the reference Currency Code Ui of commodity i；
Judge with reference to Currency Code Ui the most identical with home currency Currency Code Uc, the most then obtain and exchange unit C as centre changeAmount Ri, otherwise, obtain the exchange valency of reference currency type as intermediate variable Ri；
Read reference price Pi of these commodity i；
It is successively read the exchange valency Rj of certain marked price currency type that commodity i in table on exchange rates is used；
According to direct quotation or indirect quotation, in conjunction with intermediate variable Ri and the exchange valency Rj of marked price currency type, calculate correspondencePrice conversion factor Rij: according to direct quotation, then Rij=Ri/Rj, according to indirect quotation, then Rij=Rj/Ri；
According to price conversion factor Rij and reference price Pi of commodity, calculate the marked price obtaining these commodity i correspondence marked price currency typePij:Pij=Pi*Rij.
During calculating, ESL server is successively read every kind of marked price currency type Uj of commodity i and repeats above-mentioned calculating stepSuddenly, it is thus achieved that the price of every kind of marked price currency type Uj corresponding to commodity i.
Commercial reference currency type is not required to consistent with the home currency currency type of table on exchange rates, can be home currency or any foreign currency, and ESL takesIt automatically can be changed by business device according to above-mentioned steps.
With reference to currency type refer to commodity in the present system for recording, data exchange time marked price currency type.Every kind of commodity only makeMark the price by one specific " with reference to currency type ", and calculate other marked price currency type price of these commodity accordingly.
Such as, certain leather shoes uses dollar (foreign currency) as with reference to currency type, and marked price Pi is 20.00, calculates the people of these commodityPeople's coin price (home currency) are 120.00, yen (foreign currency) price is 2000.00.
Preferably, following initialization step is also included:
After all data item in locally stored exchange rate data table are all set to exchange unit by ESL server, to POS serverThe request of transmission updates the solicited message of the pricing information of all commodity, and is receiving the initial prices letter that POS server pushesDuring breath message, home currency kind that every kind of commodity selecting according to user are corresponding and at least one currency type of marking the price, calculate every kind of commodityMultiple Currencies price after, generate corresponding ESL explicit message and initialize the display content of ESL.
In the present embodiment, further comprising the steps of:
ESL sends to ESL server after updating display content and updates result；
The renewal result of ESL is processed by ESL server.
The communication format of exchange rate message as shown in Figure 4, include successively quotation method, home currency code, exchange unit, number,Foreign currency code, exchange valency and time stamp.[foreign currency code exchanges valency] represents the subdata item of number statistical.The definition of each data itemAs follows:
Quotation method: quotation method mark, is used for representing direct quotation or indirect quotation.
Home currency code: the globally unique code of the home currency that this message is used.Home currency is the currency type of local currency, in the exchange rateAs the reference currency type of foreign currency exchange valency in table.
Exchange unit: if using direct quotation, then it represents that the exchange trading unit numbers of foreign currency, such as 100 unit foreign currencies；If use indirect quotation, then it represents that the exchange trading unit numbers of home currency, such as 100 unit home currencies.
Number: the number statistical of subsequent child data item (i.e. [foreign currency code exchanges valency]).
Foreign currency code: the globally unique code of certain foreign currency.
Exchange valency: if using direct quotation, then it represents that the home currency price of transaction " exchange unit " foreign currency；If using indirectlyMarked price method, then it represents that the foreign currency price of transaction " exchange unit " home currency.Can use to buy in intermediate price or sell intermediate price and represent.
Time stamp: this exchange rate message update date and time.
The communication format of pricing information message is as it is shown in figure 5, include number, commercial product code, price, other data successively?.[commercial product code, price, other data item] represents the subdata item of number statistical.Each data item is defined as follows:
Number: the number statistical of subsequent child data item (i.e. [commercial product code, price, other data item]).
Commercial product code: the globally unique code of certain commodity.
Price: with the price of these commodity that home currency represents.
Other data item: other merchandise news of these commodity, the such as place of production, model etc..
Explicit message refers to that ESL can process and show the binary data on its display screen.
In the present embodiment, ESL server can obtain from the pricing information message that POS server pushes and to represent with home currencyCommodity price, and combine the exchange rate message obtained from exchange rate server, the Multiple Currencies pricing information of commodity can be calculated, and at itThe commodity price shown with home currency and multiple foreign currency on the ESL managed.When there is change in commodity price or the exchange rate, can andShi Gengxin calculates the Multiple Currencies price of impacted commodity, the display content of the relevant ESL that upgrades in time, indicates dependent merchandise in timeMultiple Currencies price.At the same time it can also be upgrade in time, exchange rate data updates time stamp, it is ensured that the readability of data and credibility.
Generally speaking, this method with electronic shelf label (ESL) as core, can according to real-time currency exchange rate information,Calculate the Multiple Currencies price obtaining commodity, and show in real time on ESL, easy to operate, timely, and environmental protection, greatly reduceError rate, when fluctuation of exchange rate, the trade loss can brought because of manual calculations mode with reduction.
