Fig. 3 shows a schematic structural diagram of a data transmission system for digital publications according to an embodiment of the present invention.

As shown in FIG. 3 , the data transmission system for digital publications according to the embodiment of the present invention includes three parts: a newspaper data terminal, a data server and a data client.

The newspaper data end includes a newspaper data server 302 and a newspaper network server 304, wherein the newspaper data server 302 stores indexed data, and the newspaper network server 304 stores data published on the Internet.

At the data service end, it includes a data acquisition server 306, a data processing server 308 and a data transmission server 310, wherein:

The data acquisition server 306 collects digital publication data from the newspaper office data server 302 and/or the newspaper office network server 304: a, signs an agreement with the newspaper office, then obtains the indexed data from the newspaper office data server 302 through a preset transmission method; b, and The newspaper office signs an agreement to grab the data published by the newspaper office in web form from the newspaper office network server 304 through the crawler.

The data processing server 308 is used for processing the digital publication data collected by the data collection server 306 . For the same digital publication data, the data collection server 306 only obtains one copy from the newspaper data terminal, and then distributes it to each display terminal 316 through subsequent processes, but the directly collected digital publication data may not be directly used for the display terminal 316 and, when the types of display terminals 316 change, such as personal computers and tablet computers, their requirements for digital publication data are also different, so it is necessary to correspond to the digital publication data according to the characteristics of different display terminals 316 processing.

The data transmission server 310 is mainly responsible for managing: 1. Authentication "authentication". It is a kind of approval used to check whether the digital publication data is authorized. If the authentication is passed, the processed digital publication data is allowed to be sent to the data transmission client 312. 2. Management data transmission client 312 . The management of the data transmission client 312 mainly includes: adding, deleting, and modifying the connected data transmission client 312 and the situation of the data transmission client 312 adjacent to it or under the same authorization.

In the data client, including data transmission client 312, display server 314 and display terminal 316, wherein:

The data transmission client 312 is mainly responsible for obtaining digital publication data from the data transmission server 310 . The data transmission server 310 can configure multiple data transmission clients 312 for the same authorized client, and can implement a p2p mode among these data transmission clients 312 to realize parallel transmission and increase transmission speed.

The display server 314 is mainly responsible for assembling digital publication data and providing services for the display terminal 316 . One data transfer client 312 can be configured with multiple presentation servers 314 . The purpose of doing this is to prevent the display server 314 from being under too much pressure when there are many display terminals 316 . The service is provided in the form of Web, so that the display server 314 and the data transmission client 312 can be separated. For example, the data transmission client 312 only needs to visit http://xxx. In addition, by separating the data transmission client 312 from the display server 314, the user can connect the data transmission client 312 to the external network and connect the display server 314 and the display terminal 316 to the internal network according to needs, thereby meeting the requirement of separating the internal and external networks .

The display terminal 316 is used to finally display the digital publication data for users to read.

By adopting the above data transmission system for digital publications, when transmitting digital publication data, as shown in Figure 4, taking the more common digital newspaper in digital publications as an example, the specific steps are as follows:

In step 402, the data collection server 306 collects data of newspapers that are allowed to operate.

In step 404, the data processing server 308 processes the newspaper data into data required by the touch screen and packs it.

Step 406 notifies the data transmission server 310 of the processed newspaper data, and the data transmission server 310 records the data information.

Step 408 , the data transmission server 310 monitors the authentication request of the data transmission client 312 .

Step 410, the data transfer server 310 verifies the request of the data transfer client 312 (verification information includes whether the data transfer client 312 is authorized and whether the maximum number of authorizations has been reached, etc.), if the verification is passed, then record the information of the data transfer client 312, If the verification is not passed, then inform the data transmission client 312 of specific error information.

Step 412, the data transmission client 312 requests the latest order information (including the information of the corresponding newspaper).

In step 414, if the data transmission server 310 finds that there is new or deleted order information (according to the order download status of the data transmission client 312), it will go to step 418, otherwise it will go to step 416. (This protocol is used to obtain information from other channels when the data transmission server 310 is down or too busy)

Step 416, return no modification order information. Then it can return to step 412 to continue the request.

Step 418, return the order information to the data transmission client 312.

Step 420, the data transmission client 312 requests the latest newspaper data information from the data transmission server 310, and returns the newspaper data information that the data transmission client 312 has downloaded and put into storage. The data transmission server 310 needs to return the latest newspaper data information and the update situation of the data status. If the data transmission client 312 has received the updated data status, it will be deleted from the cache; if the data status is not returned, it will be recorded in the cache and will be notified later. Specifically, if the data transmission server 310 needs to return the latest newspaper data information, go to step 422 .

In step 422, the data transmission server 310 calculates whether the download pressure is high (by calculating information such as the number of files being downloaded). If yes, go to step 428 , otherwise go to step 424 .

Step 424, if the pressure on the data transmission server 310 is not great, then return the latest newspaper data information (in order to allow other data transmission clients to also have the opportunity to obtain download opportunities, a maximum of 5 newspaper data information can be returned at a time, and the newspaper data information is reversed according to the periodical time return).

Step 426, after the data transmission client 312 downloads one or more phases of data, the display server 314 according to the configuration notifies them to enter the storage respectively, and periodically returns and executes step 412 to obtain the latest data and the download and storage of the returned data state.

Step 428, if the pressure on the data transmission server 310 is high, then return the information of the 5 (the specific number can be adjusted according to the actual situation) data transmission clients with the closest logical distance to the data transmission client 312, and it is necessary to ensure that these data transmission clients The downloaded newspapers include the newspapers that the data transmission client 312 needs to download.

Step 430, the data transmission client 312 records the information of the returned data transmission client, and maintains a common data transmission client list (up to 10, which is determined according to data quality and logical distance to enter this list), and sends these data transmission clients The terminal requests the latest newspaper data information (according to the order and existing newspaper data information).

Step 432, judge whether there is the latest newspaper data information on these data transmission clients, if so, go to step 434, otherwise go to step 440.

Step 434 , if the requested data transmission client has the corresponding latest data, then judge whether its network is busy, if so, go to step 438 , otherwise go to step 436 .

Step 436, if the network is not very busy (judging according to the uploaded data situation, it is generally recommended to upload 5 data, just need to wait in line), then directly return these data. After the download is completed, go to step 426.

Step 438, if the network is busy, then inform its queuing situation (that is, the position in the queue, after reaching the maximum queue, it will proceed to step 440 according to no data processing, if download data from the data transmission client that needs to be queued, then The data transmission client 312 requesting data needs to continuously request the position in the queue, and when reaching the top of the queue, the requested data transmission client will return data information). After the download is completed, go to step 426.

Step 440, if the requested data transmission client does not have the latest requested data, return the five data transmission clients logically closest to itself and the data information they have.

Step 442, the data transmission client 312 requesting data tries to connect to these data transmission clients according to the logical distance and data information of the returned data transmission clients, and selects the optimal data transmission client (ie known The data transmission client with the best data, the priority is: the data transmission client does not need to queue, the data transmission client queues) try to download the data, and update the list of commonly used data transmission clients.

The data transmission client 312 records and downloads the data information, and proceeds to step 426 after the download is completed.

In addition, in step 412, if three consecutive requests, the data transmission server 310 has no response (generally because the server is too busy or has crashed), the data transmission client 312 (according to the order and existing newspaper data information) tries to obtain the data from the common data Find the latest newspaper data information in the transmission client list, and go to step 430.

The above describes the technical solution of the present invention in detail in conjunction with the accompanying drawings. Considering that in related technologies, setting the same physical server to realize the functions equivalent to the display server and data transmission client of the present invention will cause complex deployment and reduce efficiency.
