The use that this patent is described document is in heaps or becomes piece that like this, some heaps of document just have been modified.
According to this invention, compare by means of index file, normally only determine whether after relatively to carry out long-range loading (t é l é chargement) to what revised at this.
IEEE Journal on selected areas in communication, Vol.3 No.3, in May, 1985, the USA New York, the 457-467 page or leaf, XP002041125, D.K.GIFFORD and colleague thereof: The application of digital broadcast communication tolarge scale information systeme " I joint, II joint: a kind of method of this part document description, can per four hours or when needed new version is carried out long-range loading.
The method according to this invention is just wanting to avoid this class problem.
In this part document, the whole of data are carried with dial, and each user is necessary full content or its interested content remote in the dish are loaded on his machine.This communication is undertaken by telephone network, if the distance between server and the subscriber station is too big, then cost is high.In addition, the long-range loaded data of may be maintained secrecy, and only can transmit with a network, and thus, its protection is can not be all guaranteed.
Development of Communication Technique and the more substantial access of communicating by letter make and adopt the message transmission of digital form that considerable development has been arranged.Needn't carry out inference to the physics limit that may launch quantity of radio wave or wire transmission, singly being the network operation personnel needs and will set the commerce of its investment repayment: the use valency of network is that the transmission quantity with data is directly proportional.Under identical traffic speed, this price and service time are directly proportional.
Under this background, the present invention has a selectable judgement, is used for making the information transmitted amount to minimize, and keeps using the advantage of up-to-date information fully.Native system makes the end user that optimized information display rate be arranged, is on the one hand to decide by a required big time gain of program to select to obtain new data or select the use data with existing, and be only just to load new data when needed on the other hand.
The present invention implements these methods with two kinds of methods and two devices, and operating cost is very low, and installation is easy and lsafety level is fine.
For this reason, on the dial that some unmodified information all write on the reader of a subscriber station links to each other.Server has the data of some modifications, and each subscriber station is passed in the user's that can be correlated with requirement, makes can show with the data of coiling loaded information and transmission at subscriber station.
Can be obtained by this situation: running cost is very low and fail safe is guaranteed, because have only the sub-fraction process Network Transmission of data presented and information.
For this reason, according to first kind of operational mode, the present invention relates to the method that a kind of data updated regularly is transferred at least one subscriber station and shows through digital communication network from central server, here each hope knows that more the user of new data connects its subscriber station and server, it is characterized in that the server addressed guarantees numerical data from the transmission of trend subscriber station, in the subscriber station software can:
-the data that memory has been stored and the new data of transmission compare,
If the data of-storage are all identical, the data that then do not write down on the server to be had; If the data difference of storage then activates transmission, these data are recorded in the position of the data of having stored.
-will write down simultaneously with the data of storage with show from the main information of reading dial, floppy disk or other analog relevant with subscriber station.
According to second kind of operational mode, the invention reside in a kind of will be regularly data updated be transferred at least one subscriber station through a digital communications network and show from central server, here each hope knows that more the user of new data connects its subscriber station and server, it is characterized in that server guarantees the automatic transmission of numerical data to subscriber station, the data of transmission can be shown with from the information of same in dial, floppy disk and other place relevant with subscriber station the time at software subscriber station there.
According to another kind of execution mode, use the file of a kind of being called " index " (" index ").Initial, all data all are recorded in magnetic carrier, optical carriers or above the magneto-optic carrier.
Usually, the new data on long-range server all are that Edition Contains device by carrier upgrades regularly.
One index file is arranged in the long-range server, wherein have can with the information of the version of the data on server, used carrier for information about relatively, about title, position and their feature of file available (date and the size represented with 8 hytes).
Should the time spent when on information carrier, reading, program just carries out linking first time with server, and loading " index file ".
" index " file has only information seldom, and therefore transmission is fast especially.
Compare from program information that " index " file is contained and the fileinfo on local one or more user profile memory carrier, if the file on server is new than local information, perhaps local file is modified, and then program is by with the long-range loading on the server and transaction file.
Renewal is decided by the loading frequency of " index " file, can postpone or starts " index " file automatically according to user's requirement according to a calendar, one.
This technology peculiar benefit when upgrading with known cycle, it is much bigger that the known cycle is all passed to the required time of user from server with all files.
Need come searching information opposite according to its needs with user in the network technology, file and time that method of the present invention then allows initial program editing machine oneself decision to upgrade.
According to the another kind of execution mode of this method, when the program of a user and server was connected, " index " file of server just generated automatically.
" index " file also has the date of next time revising of the file in server.
Various information all are recorded on the identical carrier with initial application (can heavily write down CD).
The invention still further relates to a kind of device, be used for implementing above-mentioned method.According to first kind of operational mode, this device is characterised in that and comprises:
-one central server, data updated regularly wherein,
-one digital communication network is used for giving at least one subscriber station with data from Server Transport,
-at least one subscriber station, the formation of each subscriber station is: be the storage system of " index " file on the one hand, that server transmitted and data record are wherein arranged, be the comparison system of " index " file on the other hand, data available, another index file that one of them index file has on server have the data of storage or record, if in the index file of transmission, do not revise, then keep the data of having deposited; If modification is perhaps arranged, then carry out long-range loading, replace the data of having stored with the available data of transmitting " index " file in server that comes.
-for each subscriber station the reader of dial, floppy disk or other type is arranged all, and
Display in the time of-one " index " file wherein has the various information of dial, floppy disk or other analog of the data of storage and each subscriber station.
The present invention also is a kind of device that is used for implementing this method, according to second kind of execution mode, it is characterized in that comprising:
-one central server, data updated regularly wherein,
-one digital communications network is used for data are passed at least one subscriber station from server,
-at least one subscriber station,
-for each subscriber station the reader of dial, floppy disk or an analog is arranged, and

Fig. 2 is the schematic representation of apparatus according to second kind of execution mode of the present invention, is used for implementing second kind of operational mode of this method.
The invention reside in the transmission and the display packing of two kinds of data, and two kinds of devices that are used for implementing these two kinds of methods.
Shown in Fig. 2 is the execution mode of having simplified according to device of the present invention a kind of.
Mainly contain a central server 11 long-range with subscriber station 13 at this device, server 11 and subscriber station 13 being connected each other is by a communication network 12, and this communication network also can be to be made of a telephone network.
Certainly, server 11 can be connected with very many subscriber stations 13, and for easy to understand, a subscriber station 13 in the drawings only draws.
Each subscriber station 13 is made of a dial reader 16.In each dial, information 17 is arranged on the one hand, also have the zone 18 of some skies on the other hand, can be used for receiving data from server 11.
This is just very clear, and this system can be used by the company that makes, sells or have a distributed network.If these enterprises wish that electronic link is transferred to distributors arranges, also be to be suitable for fully according to system of the present invention.Because this system maintains regular and can guarantee commerce services, this is that commercial staff institute is unwarrantable.This device can technology in the past have rapid and reliable operation by its network on the other hand, standard and file that the past technology will be operated by telecopy.In addition, this system can also the renewal technology file and the operation of components by method for simplifying guarantee after-sale service.
Like this, if a kind of price of commodity need be known or some product in the catalogue is promoted that this distributors just can read dial, in the hope of obtaining the general information in the catalogue, for example introduction, reference, figure or the like by distributors.Server 11 just is transmitted in the data that do not have on the data disks by network 12.Whether can also relate to the value that those are often revised, be as the commodity of promoting as price, quantity in stock or this commodity.
Method according to transmission of the present invention and demonstration is exactly at distributors screen place a file that will upgrade to be arranged, on the one hand dial institute loaded information is arranged in this file, this fixes, and the data from server 11 are arranged on the other hand, these data change, but always can upgrade.
From this as can be seen, minimize because only transmit variable data the turn-on time that subscriber station 13 and server are 11, therefore price is just very cheap, and the data of transmission do not have relevant with information in the dial, this is just as safe as a house, because can not get a thorough understanding of during the information of any people who wonders content wherein in no compact disk.
According to Fig. 1, the execution mode of the device of addressing can complexity a bit so that service is more reliable.
According to this mutation, increased near subscriber station 3 between server 1 and subscriber station 3: a data storage system 4, another is data that will storage and the comparison system 5 that the data of transmission compare.
In this operational mode, distributors is connected with server 1 by digital communication network 2 at subscriber station 3 places.Thereafter server 1 sends the relevant data of the file that it had to the comparison system 5 of subscriber station 3 by digital network 2.The data that before comparison system 5 places have stored, received.If about the data of the file that on server, has identical with the data of the file of having deposited, then on the data of being deposited without any variation.On the contrary, if the data that the data that receive have been deposited more have a change, then new remote data is loaded, and replace the legacy data of having deposited, this storage is carried out in system 4.
With the same in Fig. 1, each subscriber station 3 all is made up of a dial reader 6, and each dial all is on the one hand information 7 to be arranged, and the free space 8 that is used for receiving from the data of server 1 is arranged on the other hand.
When its supplier's catalogue will be read by distributors, he only needed reading on the screen from the various information of dish 7 and the data at the white space 8 of dial that are stored in storage system 4 and will show on screen.
Such system can improve the quality of products ﹠ services and improve the prestige of multi-brand distributors, the network that can form distributors can upgrade the data of variation very fast, managed inventory as quickly as possible, very fast feedback information can be arranged, and be to make that the telephone service of selling with after sale is minimum at last.
Various technical purposes are compatible and hard-core management that are connected simultaneously of the simplicity of server and client enforcement, the simplicity of upgrading Data Control, multi-platform client.
At last, financial purpose is the enforcement of radio communication expense minimum, server and structure that links to each other with server and maintenance cost minimum.
For the client, the client has very abundant and reliable information, the low price of the fast access of these information, connection material requested.Because this system can be used for traditional personal computer, therefore also relate to using and oversimplify, be to shorten the operating time at last.
In the technical scheme of this problem, can suppose that article need a coding of 8 characters, a kind of article also are 8 characters, also will add 8 characters of information such as relevant size, color, draw the data of a kind of article corresponding to 24 eight bit bytes thus.
For the inventory of 10000 kinds of commodity, its amount of information is exactly 240,000 eight bit bytes, i.e. 234.3Ko.At the 2Ko that is connected to of situation following each second of current structure, for this situation, the transmission time of full detail is very short, and about 100 seconds, more the quantity of new commodity then was a lot.
