The operation description of the conventional kiosk system configured as described above is as follows.

First, when a user of the terminal device 1 requests specific information through the input unit 11, and generates a specific information request signal, the control unit 13 transmits a specific information data call signal for calling information desired by the user. 13).

The network matching unit 13 matches and outputs a specific information data call signal to the transmission network 3, and the specific information data call signal transmitted through the transmission network 3 is transmitted by the network matching unit 4 to the central information service device. Matched to (2), it is transmitted to the control unit 22.

The control unit 22 decodes a specific information data call signal and then controls the data storage unit 21 to output the information data requested by the user, while controlling the information data output from the data storage unit 21. The data control signal is output to the multiplexer 23.

The data storage unit 21 outputs the information data requested by the user under the control of the control unit 22. At this time, the information data stored in the data storage unit 21 is compressed information data and is in a compressed state when outputted. The multiplexer 23 multiplexes the compressed information data of the data storage unit 21 and the information data control signal of the control unit 22 and outputs the multiplexed data to the network matching unit 24.

But in the case of home shopping, education, or guided kiosk systems, there is often information that customers often request for the same information.

Therefore, when the user of the kiosk system requests the same information to be repeatedly displayed for searching or selection, the amount of data output from the central information service device increases, causing a problem in traffic. Since information is displayed through the information transmission path, it takes a lot of time to transmit the information, so that the interaction with the user is not smoothly performed.

The present invention has been made to solve the above problems, the kiosk system and the memory scheduling control method having a memory scheduling function to facilitate the conversation of the kiosk system by storing the information frequently requested by the customer in the terminal device The purpose is to provide.

Hereinafter, with reference to the accompanying drawings will be described an embodiment of the present invention;

FIG. 2 is a hardware configuration diagram showing an embodiment of a kiosk system having a function of memory scheduling according to the present invention. In the conventional terminal apparatus 1 shown in FIG. 1, the demultiplexer 14 A buffer 31 for storing the compressed information data, the identifier of the compressed information data, and the information data call time output through the buffer 31, and when the data storage 21 outputs a specific information data call signal, An identifier is assigned to the information data transmitted in response, and a time at which a specific information data call signal is generated is detected so that the call time of the identifier data and the identifier data is stored in the buffer 31. Further comprising a memory scheduler 32 that controls information data that is frequently requested by the user to be stored first. In addition, the controller 12 receives a specific information request signal from the input unit 11 and searches for information data requested by the user from among the information data stored in the buffer 31 from the memory scheduler 32. If the information data is stored in the buffer 31, the user and the request information data stored in the buffer 31 are controlled to be output to the information data expansion unit 15, and the information data requested by the user is stored in the buffer 31 If not, it is configured to further include a function of outputting the specific information call signal to the network matching unit 13 so as to control the information data transmitted in response to the specific information call signal to the information data extension unit 15 as in the prior art. do.

An operation description of a kiosk system having a memory scheduling function configured as described above is as follows.

First, when the input unit 11 generates a specific information request signal, the control unit 12 searches the memory scheduler 32 for information data requested by the user from among the data stored in the buffer 31 and the user in the buffer 31. If the requested information data is not available, a specific information data call signal is output to the network matching unit 13.

The specific information data call signal is matched by the network matching unit 13 and transmitted to the central information service device 2 through the transmission network 3, and the central information service device 2 responds to the specific information data call signal. The compressed information data and the information data control signal required by the terminal are transmitted to the terminal device 1.

The information data and the information data control signal inputted to the terminal device 1 through the network matching unit 13 are separated by the demultiplexer 14 so that the information data control signal is input to the control unit 12 and the information data is buffered. And input to the information data decompression unit 15.

Therefore, the compressed information data inputted to the information data decompression unit 15 is expanded to the original information data and then displayed on the monitor 17 under the control of the image control unit 16.

On the other hand, the memory scheduler 32 receives the call time for the information data currently input to the buffer 31 from the control unit 12, assigns an identifier to the information data input to the buffer 31, the identifier is assigned The call time of the information data and the information data given the identifier is controlled to be stored in the buffer 31.

Therefore, the buffer 31 stores the compressed information data requested by the user, the identifier of the compressed information data, and the information data call time.

If the user continues to request information through the input unit 11, when there is no information data requested by the user in the buffer 31, the new information data requested by the user is sequentially stored in the buffer 31 by the above operation. do.

However, if the search result for the information data requested by the user among the information data stored in the buffer 31 from the memory scheduler 32 is stored in the buffer 31, the controller 21 ) Controls the user request information data stored in the buffer 31 to be output to the information data decompression unit 15 so that the information data decompression unit 15 decompresses the original data.

Therefore, the compressed information data stored in the buffer 31 is expanded to the original information data and then displayed directly on the monitor 17 under the control of the image control unit 16, which is much faster than the conventional kiosk system.

On the other hand, when the memory scheduler 32 receives a confirmation request signal indicating whether the information data requested by the user is stored in the buffer 31 from the control unit 12, the memory scheduler 32 uses the identifier of each information data stored in the buffer 31. If the information data requested by the user is stored in the buffer 31 and the information data requested by the user is stored in the buffer 31, the call time stored with the information data is updated to the current time. The controller 12 informs that the information data requested by the user is stored in the buffer 31.

However, if the information data requested by the user is not stored in the buffer 31, the memory scheduler 32 transmits the result to the control unit 12, and in response to the specific information data call signal of the control unit 12, An identifier and a call time are given to the information data transmitted from the information data service device 2 and controlled to be stored in the buffer 31.

At this time, the memory scheduler 32 assigns an identifier and a call time to the information data transmitted from the central information data service device 2 in response to the specific information data call signal, and stores the buffer 31 in the buffer 31 before storing it in the buffer 31. If the information storage state of the buffer 31 is full, the information storage capacity of the buffer 31 is retrieved to remove the information data having the longest call time and store the newly input information data.

Therefore, according to the kiosk system of the present invention, when the information data requested by the user is stored in the buffer 31, the call time of the information data is updated to the current time, and the information data requested by the user is stored in the buffer 31. If the information data storage state of the buffer 31 that is not present is full, the information data frequently requested by the user is stored in the buffer 31 because the information data newly input after the information data with the longest call time is removed and stored. Is stored first.

FIG. 3 is a detailed flowchart illustrating a memory scheduling control method of the present invention using the kiosk system of FIG. 2.

First, when the memory scheduler 32 receives a confirmation request signal indicating whether the information data requested by the user is stored in the buffer 31 from the control unit 12 (301), the memory scheduler 32 stores the information of each information data stored in the buffer 31. The identifier checks whether the information data requested by the user is stored in the buffer 31 (302).

As a result of the search, if the information data requested by the user is stored in the buffer 31, the call time stored with the information data, that is, the past call time is updated to the current time and controlled to be stored in the buffer 31 (303). The controller 12 notifies the controller 12 that the information data requested by the user is stored in the buffer 31 (304).

When the controller 12 is informed from the memory scheduler 32 that the information data requested by the user is stored in the buffer 31, the controller 12 controls the buffer 31 so that the user request information data stored in the buffer 31 is extended to the information data. Output to section 15.

However, if the information data requested by the user is not stored in the buffer 31, the memory scheduler 32 notifies the controller 12 of the result (306) and retrieves the data storage capacity of the buffer 31 (307). When the information data storage state of the buffer 31 is full, the information data having the oldest call time is detected (308) and then erased (309).

On the other hand, the controller 12 notified from the memory scheduler 32 that the information data requested by the user is not stored in the buffer 31 transmits a specific information data call signal to the central information data service device 2, In response to a specific information data call signal of the control unit 12, when the user requests the information data requested by the central information data service device 2 (310), the control unit 12 receives the information data service device 2 from the central information data service device 2; The transmitted information data is controlled to be input to the information data decompression unit 15.

In addition, the memory scheduler 32 controls to store the buffer 31 by assigning a new identifier and a call time to the information data transmitted from the central information data service device 2 (312, 313).

As described above, the present invention allows information data that a user frequently requests to be stored in the terminal device, so that the information stored in the terminal device can be used without receiving the service of the central information data service device. It reduces the time to use the information, facilitates the conversation with the user, and in the case of the central information and data service device, the burden on the user is reduced, thereby serving more customers.
