Description

Digital signage system {Digital sinage system}

The present invention relates to a digital signage system, and in particular, even when an error occurs in the main server that plays a pivotal role in the digital signage, the digital signage system characterized in that to provide information stably at each terminal. It is about.

Digital signage (Digital Sinage) is a centralized management to output a certain data to a plurality of client terminals, such terminal is fixedly provided in a predetermined place as shown in Figure 1 used by the visitors who visited the place In addition to this, it can be defined as a system that provides additional data desired by active participation of visitors.

Specific application examples of such digital signage include presenting promotional videos, employee organization charts (FIG. 2) and bulletin boards to visitors, and enabling data processing / editing by specific participation of the visitor. It can be used for public facilities such as corporations, government offices, airports and terminals.

The specific characteristics of such digital signage are as follows.

1) The client terminal does not simply send data to the center in one direction. Instead, the client terminal selects the data by requesting additional data.

In this regard, [internal broadcasting], which is provided for the convenience of the user in public places such as buses, trains, trains, and banks, provides a one-way screen to differentiate the client terminal.

2) The client terminal does not actively lead the server to receive information continuously, but usually merely displays the data provided from the server, which is a basic property that the client terminal is provided for public use. Originated from.

In this respect, a general computer network system composed of a server / client is connected to a server by a client side request, and data transmission in the connected state is only required by the client side. This is due to the property that a client of a computer network system is provided for personal use.

3) The data provided by the client terminal is extremely fatal due to the error or error due to the nature to be provided for public use. Moreover, due to the public nature, there is a high concern about hacking from the client terminal to the server side, and the damage is also very serious.

In this respect, [IPTV (bidirectional TV)] is distinguished from the fact that there is no catastrophic damage other than consumer dissatisfaction even if the broadcasting service is not properly provided due to the characteristics provided for personal benefit only.

In other words, digital signage is mainly for providing information in public places such as corporations and public offices, not for personal leisure, so it is not merely for pleasure or time consuming, but for providing public information. will be.

Therefore, if a failure of the whole system occurs and the provision of information is interrupted, this is not only a loss of unnecessary information, but a public interest that must receive public information is violated. It will also be seriously infringed.

In order to compensate for this, it may be a way to provide a backup system. However, this may result in "inefficiency of the system."

In addition, if it is possible to perform a normal function in the client terminal in the event of a fault of the entire system without additional equipment or system supplementation, the burden on the urgent AS or the complaints of the administrator is greatly reduced, which is very useful for the introduction of the system. It will act as an element.

At this time, the configuration of the conventional signage system is as shown in FIG.

That is, a plurality of client terminals for outputting information about one main server performing centralized management are individually configured in a 1: 1 connection, but each client terminal is connected via a main server. Since it is separated by separate hardware, if an error occurs in the main server and does not perform a function, the individual terminal is isolated as shown in FIG. 4 and thus does not perform a proper function.

The present invention is to solve the above technical problem, to ensure the bidirectional, public and stability of the digital signage by allowing the client terminal to exhibit the original function in spite of the error of the main server, in particular the client terminal Given that the data actively requested by the party are fragmentary data rather than comprehensive and extensive data, the purpose is to provide a digital signage system that can reduce the burden on cost and reliability with a simple additional system.

Furthermore, an object of the present invention is to provide a digital signage system capable of quickly and accurately responding to request information of various customers by listing and statistically updating and transmitting and receiving information between respective terminals.

Digital signage system according to the present invention for solving the above problems is composed of a main server and a plurality of terminals provided in a predetermined place to provide information to the visitor,

In particular, a bypass line is additionally provided between the lines connecting the plurality of terminals, respectively, in the middle, and the main server has a connection between the plurality of terminals and a plurality of terminals through the bypass line when the main server fails. There is an additional feedback server to coordinate the connection of

The feedback server checks the transmission / reception information of the terminals, lists and stores them, and checks / lists module which sends the list to the terminals or requests of the terminals or periodically; An identification information module that stores the embedded unique number of each terminal and checks the validity of the embedded unique number transmitted by each terminal whenever there is a request for data or the connection with the feedback server is reset; It generates a one-time password including the one-time password algorithm of each terminal, checks the validity of the one-time password transmitted by each terminal, checks the validity and lists it and stores it, and requests the terminals or periodically lists the list. In case of main server error, one terminal requests the data by enclosing the latest one-time password of the corresponding terminal to the other terminal and checks whether the other terminal is the same as the one-time password that was recently generated by the other terminal A one-time password module for checking the validity of the terminal; And a statistics module for statistically storing the location, data type, and request time of the terminals.

In the event of a main server error, one terminal provides the information requested from the visitor and provides it among the data stored on its own, or a list containing the transmission / reception information of the other terminal received through a feedback server and the disposable password list. Based on the received from the other terminal to provide from the data, it is characterized in that to provide stability of the information provision.

According to the present invention as described above, in spite of the error of the main server, the client terminal can provide the information requested by the visitor through the other terminal in real time, thereby exerting the original function, thereby providing bidirectionality, publicity, Stability can be secured, and the burden for urgent A / S on the manager's side and the burden on civil complaints can be greatly reduced.

Furthermore, the present invention stores identification information unique to each terminal, and then verifies whether the identification information is valid whenever there is a request for data from the terminal, thereby preventing access of a malicious terminal that is no longer valid by hacking or the like. It works.

Meanwhile, the present invention not only can update and receive information of each terminal periodically, list them, and statistically respond to them more quickly and accurately. It is possible to increase the utilization by differently provided data.

DETAILED DESCRIPTION Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

5 is an overall configuration of a digital signage system according to the present invention, wherein each terminal and the main server are connected by a bypass line, and a feedback server for ensuring bidirectionality, publicity, and stability is provided between the main server and each terminal. 6 is a view showing the components of the feedback server in detail, Figure 7 is a configuration when the main server error occurs and each terminal directly checks the list and transmits and receives information by itself 8 is a flowchart illustrating a flow in which each terminal directly checks a list and transmits and receives information when a main server error occurs.

As shown in FIG. 5, the digital signage system according to the present invention is mainly composed of terminals 210, 220, and 230 and a main server 100 connected by a line, and in particular, a bypass line connecting an intermediate line between the lines. 300 is added. At this time, the bypass line 300 is representative of the additional line that physically connects the connection line, but can also be any means to enable the signal connection between the terminals, thereby the terminals (210, 220, 230) Even if the main server 100 does not pass through to secure a direct connection path.

The main server 100 is further configured to be connected to the feedback server 150 at the front end of the terminal, the feedback server 150 is located between the terminals 210, 220, 230 and the main server 100 By adjusting the connection between the terminals (210, 220, 230) or information transmission and reception of the terminals.

Specifically, as shown in FIG. 6, the feedback server 150 is divided into a check / list module 151, a statistics module 152, and an identification information module 153.

The check / list module 151 checks the transmission / reception information of the terminals 210, 220, 230, lists them, stores them, receives the list transmission command of the terminals 210, 220, 230, or Actively sent to the terminal (210, 220, 230) at a specified time or a certain period.

These lists are preferably updated periodically, and thus the modified list is transmitted to each terminal through the feedback server 150, and the terminals 210, 220, and 230 are valid times of the information (eg, For example, the deadline, information including the end time) and the usefulness of sharing with other terminals (for example, information to be delivered only to a specific region or terminal) may be checked and stored in the list.

The statistical module 152 statistically stores the location, data type, and request time of the terminals 210, 220, and 230.

The identification information module 153 includes an embedded unique number uniquely secured by each of the terminals 210, 220, and 230, and each time there is a request for data or a connection with the feedback server 150 is reset. Check the validity by checking the identity with the embedded unique number transmitted by the terminals (210, 220, 230).

Therefore, if an invalid terminal is connected, the transmission and reception of data is restricted, and the feedback server 150 updates the information that the arbitrary terminal is no longer valid through the identification information module 153 and transmits it to another terminal. This prevents data sharing between terminals.

The one-time password module 154 generates a one-time password including the one-time password algorithm that each terminal has, and checks the sameness as the one-time password transmitted from each terminal at the request or specified period or period Check the validity. In this way, the list is stored every time the identity of the one-time password is checked, and each terminal 210, 220, 230 is always up-to-date by sending it to each terminal at the request of the terminals or at a designated time or a predetermined period. Of course, it is possible to hold a list of one-time passwords generated by other terminals.

However, since each terminal does not have a one-time password algorithm of the other terminal, it simply stores the encrypted one-time password and does not decrypt it.

And each terminal is to remember the one-time password information sent by them recently, if received from the check / list module 151 of the feedback server 150 in the disconnected state with the main server 100 side When receiving and requesting new data to the corresponding terminal by using the other terminal storage list, the terminal transmits the encrypted one-time password recently sent by the terminal and the terminal has recently sent the one-time password sent to the feedback server 150. By checking the identity of, the transmission of data is allowed in the same case.

Therefore, the check / list module 151 of the feedback server 150 according to the present invention sends a list to each of the terminals 210, 220, 230, and the terminals 210, 220, 230 are the main server. If an error occurs in 100, one terminal may receive information through the other terminal in real time based on the list after receiving validity confirmation through the identification information module 153 or the disposable password module 154. It is.

In addition, the information is divided into broadcast material including a promotional screen that is normally displayed, and request data provided separately from the main server 100 according to a user's request, when an error of the main server 100 occurs, The feedback server 150 checks whether the broadcast data or request data is included in the list of information stored by the terminals 210, 220, and 230, and thus, the terminals (not depending on the main server 100). Information may be transmitted between 210, 220, and 230.

That is, as shown in FIGS. 7 and 8, when an error occurs in the main server 100 and each terminal 210, 220, 230 detects this, each terminal 210, 220, 230 is basically itself. By outputting the stored broadcast data it is possible to implement a normal function, if there is a request of data from the visitor, it is searched in the transmission and reception information list, and if the corresponding request data is stored on its own, it is displayed.

However, if it cannot be stored because it has not received the request itself, check whether the request of the data was received from the other terminal in the transmission / reception information list. The terminal checks the one-time password that the terminal has recently sent to the feedback server 150 from the list of passwords and requests the data while enclosing it through the bypass path 300, and the other terminal has recently created the one-time password with its own one-time password. Check if it is the same and send the requested data if it is valid.

Therefore, even if an error occurs in the main server 100, each terminal can implement the normal function by providing the visitor's request data using the bypass path 300 with the help of other terminals.

Therefore, the present invention described above is capable of providing a normal function through data transmission between terminals in spite of a defect of the main server 100 to secure the bidirectionality, publicity and stability of the digital signage, which is urgent for the manager side. The burden for A / S and complaints can be greatly reduced.

In detail, each of the terminals 210, 220, and 230 stores the list of stored data received by the feedback server 150 for each type, and updates the same data with the latest data, followed by the main server 100. If an error occurs, each terminal recognizes this and ends the dependence on the main server 100 to display the stored data.

That is, when the connection with the main server 100 is terminated, the stored broadcast data is displayed to enable continuous broadcasting, and when the user requests a data for request data such as an organization chart, the data has never been previously requested. If the data is stored, it can be displayed without relying on the main server 100 by displaying it.

However, when the connection with the main server 100 is terminated as described above, a request for data from the user may occur, but the data may not be stored because the corresponding data has not been requested by the corresponding terminal.

Even in this case, since each terminal is connected to the other terminals in a bypass path, the terminal may provide the stored data with each other without the help of the main server 100, thereby more fully responding to the user's request.

The present invention has been described above with reference to the accompanying drawings and the above embodiments, but the present invention is not limited only to the embodiments related to the accompanying drawings and the digital signage system.

It will also be understood by those skilled in the art that modifications can be made in accordance with the spirit of the invention, and such modifications also fall within the scope of the invention.
