Description

Library Seat Use and Display System {A Sheet Information Display and Management System}

The present invention relates to a system for displaying and managing the use of library seats, and more particularly, in real time, whether a user is absent by using a sensor so that a library occupancy can be prevented from occupying a seat where a user occupies a book and leaves a seat for a long time. The present invention relates to a library seat usage display and management system that can increase the turnover rate of a seat by recognizing and displaying it through an indicator so that other users can sit in an empty seat after a certain absence time.

Today, for colleges or public libraries where the reading room is free, there is always a shortage of seats compared to the number of people who use the reading room. This is true even though the number of seats is small, but because the users leave their seats with books and leave the seats for a long time, the empty seats are not operated efficiently. To this end, the library manager regularly arranged the neglected seats, but it was difficult to organize all the books on the empty seats because it was not clear whether the empty seats were left for a long time or were left empty for a while. Therefore, there is a need for a new library seat management system that allows library managers or users to easily recognize empty seats that have been left unattended for a long time.

On the other hand, conventionally, a reading seat seat issuer is used to solve the problem of occupying a seat in a library.

The reading seat seat issuer is installed in a reading room entrance or the like so that users can receive a seat by inputting a smart card or a social security number. At this time, the users should continue to reissue the seat when the time set by the administrator.

However, such a conventional reading seat seating machine is composed of complicated digital devices, and is used only in a large library because it is expensive to install (for example, an average of 85 million won for 600 seats). In addition, maintenance and management not only required manpower and cost, but also required a large installation space that users could use in line.

In addition, a smart card or social security number is required, causing a human rights violation on personal information.

In addition, the seat can be used as much as the time set by the administrator, so when the time to use the seat has to be reissued, it is cumbersome and inconvenient. That is, when the seat assignment time is short, the reading room user has to go to the reading seat seat issuer and reissue the seat every time the seat use time is troublesome and inconvenient. There is a problem.

On the other hand, in a small reading room such as a school library, when a user leaves the seat for a while, the time is written down on a memo or a memo so that other people can use the seat at that time. However, this method also has a low participation rate because users who are not used to sharing a place with others feel bothered and uncomfortable taking notes.

In order to solve this problem, Korean Patent No. 1016824 (2011.02.15.) (Hereinafter referred to as 'prior invention') installed an infrared sensor under the table of each seat to detect the use of the seat, Disclosed is a display apparatus for displaying a seat using or using an infrared sensor installed at an upper portion of a table of each seat according to a detection signal of an infrared sensor.

The preceding invention has the advantage of solving the seat occupancy problem by displaying the library seat so that other users can use it through an indicator installed in each seat by the infrared sensor when the user is left for a predetermined time or more. However, since the preceding invention displays only the current use of the seat through an indicator installed in each seat, there may be a fertilization between the user who takes the seat first and the user who sees the seat as an empty seat. That is, the preceding invention may cause a seat dispute between the user sitting at the seat and the user who came to the seat afterwards because the indicator is operated again when the person is seated. In this case, it is not possible to prove the time when the seat users are away, which may lead to emotional fights and complications.

In addition, the preceding invention has a problem that the indicator indicating the use of the seat is installed only in each seat is a problem that the library administrator can not be checked and managed in one place.

In addition, the foregoing invention has a disadvantage in that it is cumbersome and inconvenient to replace the battery periodically because the infrared sensor and the indicator installed in each seat are configured to operate by the battery, there is a disadvantage that the maintenance cost is high.

The technical problem to be solved by the present invention to solve the above problems, by detecting the use of the library seat using a sensor to indicate whether the seat using the seat display device installed on each seat, to prevent preemption of the library seat In order to maximize the efficiency of library seats by increasing the turnover of seats, the present invention provides a system for displaying and managing the use of library seats.

In addition, another technical problem to be achieved by the present invention is to recognize the use of each seat in real time by a sensor attached to each seat of the library, and if the seat is left for a predetermined time or more through a seat display device installed on each seat The present invention provides a library indicating whether seats are used or not and managing a system.

In addition, another technical problem to be achieved by the present invention, by connecting the seat display device and the seat management device installed on each seat through a wireless or wired communication network library administrators can check and manage the use of each seat through the monitor To provide a system for displaying and managing the use of library seats.
