Description

Intelligent signage content delivery device combined with human cognition and data analysis techniques}

The present invention relates to an intelligent signage content delivery device combined with human cognition and data analysis techniques, and more specifically, to increase user's curiosity by human cognition techniques and to deliver customized and intelligent content through data analysis techniques. It relates to a signage content delivery device.

Digital signage is a communication tool that enables companies to install digital displays that can be remotely controlled over a network in public or commercial spaces to drive marketing, advertising, training and customer experiences for businesses. It is a digital video device installed in a public place such as a hotel, a hospital, and providing specific information as well as a broadcast program.

These digital signages have recently provided advertisement information in a form that enables communication with a user who views the advertisement information in addition to providing unilateral advertisement information.

As part of such development, a technology for providing user-specific information by using user information is being developed. For example, Korean Patent Publication No. 2015-0077529 (published on July 8, 2015) shows that digital signage uses NFC or RFID tags. When a user tags a digital signage using a terminal equipped with an NFC or RFID tag, information related to the advertisement displayed on the digital signage is transmitted to the home server of the home. A configuration is disclosed in which such information can be used through a home display of a home.

However, such a prior art has a problem in that even in the case of a mobile terminal not equipped with NFC or RFID, the advertisement content provided by the digital signage cannot be accessed even by an advertisement target user matching the advertisement target.

In addition, the above-described prior art provides specialized information only to a user who is preset through NFC or RFID, and there is a problem that any user who is not preset cannot receive information that is suitable for them.

On the other hand, digital signage operated by network distributes / updates, operates, and manages contents in a central server, so a system that can effectively distribute and manage contents is needed. WebDAV, Cach Server, CDN according to system construction method Services, cloud services, etc. are used.

On the other hand, due to the rapid spread of smart devices and wider network (Wi-Fi, LTE, etc.) in the information and communication technology market, data transmission volume of high-definition video contents and sound source contents is rapidly increasing. We use CDN (Content Delivery Network) service to quickly and reliably service traffic concentration, bottleneck, and data loss that occur frequently in the process.

CDN service is an Internet service provider (ISP) that has a large amount of content stored on a web server of an existing content provider (CP) or that has high demands. It is a technology that pre-stores in the CDN cache server installed on the provider side and delivers the contents to the user by the optimal path from the CDN cache server.

In the general Internet structure, the content is delivered from the CP server to the user through complex paths such as ISP's backbone network, IX (Internet Exchange), and subscriber network, but the CDN service does not go through the bottleneck for content delivery. Since the content is delivered from the nearest point of the user, a fast and stable service is possible even when the user suddenly explodes.

However, the CDN service uses servers distributed to ISPs rather than its own network, which incurs high costs and cannot be used in an intranet, which is a closed local area network using Internet protocols. Independence and scalability are low for individual operators or small businesses, and the service quality of file transfer cannot be absolutely guaranteed unless a CDN cache server is installed in advance.

Therefore, in terms of management or cost, there is a limit for small operators to establish an independent CDN service network. In addition, the HTTP protocol used in the CDN service has a problem that it is slow to send and receive a large amount of files in a batch, and file control is cumbersome.

Although not shown, the apparatus may further include a landmark detector for detecting a landmark in an image acquired from a camera. The web server or the master server outputs landmark-related content to the corresponding signage device according to the detected landmark. Control as possible.

In addition, the present invention further includes a submaster that helps to expand the terminal role and the network network to transmit the file to the slave and report the slave status result to the master server as shown in FIG. 3.

The web server is connected to a content provider (cp) and a master server constituting the content management system as shown in FIG. 4, and information about a file uploaded from the content provider (CP) to the master server (File Information) and the master server. The information of each slave is stored, including the slave ID transmitted via SNS. This web server provides all the file information uploaded to the master server, and serves to minimize the load on the output device or smart device download by the slave.

As shown in FIG. 5, the master server stores and manages the information of the file uploaded from the web server, where the actual file first transmitted by the CP is located. The file information and file are transmitted to the submaster and slave connected to the master server for file distribution.

As shown in FIG. 6, the submaster serves as a terminal for smooth communication between the master server and the slave, and serves as a means for further expanding the file distribution network.

As shown in FIG. 7, the slave can no longer be extended to the terminal device and finally transmits a file corresponding to an output device or a smart device.

The file distribution process between the master server and the slave by such a device will be described in more detail below.

4 is a diagram for transmitting related file information to a web server when file transfer is completed using FTP from the CP to the master server. The internal database running on the web server stores the slave information and the transferred file information. Slave information consists of FTP server number, slave ID, slave FTP information, slave size, etc., and file information consists of file number, file name, file size, file upload time, master server FTP number, file distribution result, etc. do.

The master server gets the information of the transferred file from the web server's database and transfers the retrieved file information and file to the submaster and slave connected to the master server. In addition, upon completion of file transfer to the slave slave terminal, the master server stores the slave ID in a bit format in the corresponding position of the database file distribution result field using the file number of the file information received from the sub master and the slave.

The sub master and the slave store commands (ADD, DEL) and file information (file number, file name, file size, file MD5) received from the master server in a queue, and perform file addition and file deletion according to the stored commands. If the command to add a file is used to access the master server via FTP based on the file information stored in the queue, the file is downloaded. If the command to delete a file is deleted, the file in the submaster and slave is deleted. When one command operation is completed, the execution result (command, slave ID, file number) is reported back to the master server.

6 is a diagram for transferring files and file information from a submaster to a submaster and a slave.

The submaster and the slave store the command and file information received from the submaster in a queue and perform file addition and file deletion according to the commands stored in the queue as in FIG. 5. In addition, unlike the master server, the submaster is a medium for transferring file and file information between the master server and the slaves, which greatly expands the file distribution network and distributes the files to multiple slaves, thereby increasing the overall file transfer speed and providing safe and secure service for users To receive it.

FIG. 7 is a diagram illustrating that a user can quickly and securely receive a service by applying a slave load on a web server based on slave ID result information collected from a master server. In order to reduce the load of the file transmitted from each slave, localization, bandwidth, and transfer amount are considered. Localization can operate independently master server, so it can be separated and configured according to the purpose of use by using multiple master servers, and bandwidth is based on slave size, which is slave information of database, and multiple output devices and smart devices connected to one slave. We limited the number of devices so that they can be sent as quickly as possible. Finally, the slaves can be used evenly based on the amount of files transferred in real time for each slave in the database.
