Description

An intelligent seat arrangement system for a library

technical field

The invention relates to a seat arrangement system, in particular to an intelligent seat arrangement system in a library, which belongs to the field of library management.

Background technique

The intelligent seat arrangement system of the library is relatively common in current applications, such as: smart seat systems such as Qunar library, etc. The general system includes: online seat selection, system seat arrangement, personnel use, overtime recovery and other continuous steps, but these The systems are based on existing library equipment such as chairs and desks. In order to save money, no changes have been made to the existing chair desks. Although the utilization efficiency of the chairs in the library has been greatly improved, some readers will occupy more chairs and move the chairs away from their original positions. cannot be handled effectively.

If the library manager fails to detect and stop this behavior in time, it will cause subsequent readers to choose a seat on the system, but there will be no chairs to sit in after arriving in the reading room.

Existing systems and devices are completely devoid of features to prevent such things from happening.

The technical means for solving this type of problem in the prior art include:

1. Install a fixing device on the seat to limit the movement of the seat; the disadvantage is that the readers are uncomfortable due to the different heights of each person.

2. Install some kind of tracking function to call the police after moving, and the management staff will stop it; the disadvantage is that on the one hand, it will affect the surrounding readers; on the other hand, when the management staff is insufficient, it cannot respond to such problems faster.

Therefore, a seating system is needed in the library to intelligently manage the status of readers and seats.

Contents of the invention

The object of the present invention is to provide a library intelligent seating system, including: a reader reservation system, an administrator system, a central processing system, a control system, and a special seat for the library seating system installed with a library seat tracking device .

The workflow of the above-mentioned library intelligent seat arrangement system is:

1. Before the opening of the library, the administrator system sends all seat valid instructions to the central processing system;

2. The central processing system decomposes the command into two parts, one part directs the reader reservation system to release all seats, and the other part directs the control system to send a signal to activate the electromagnetic induction device;

3. All seats are available for use at the beginning;

4. The reader sends a seat request in the reader reservation system. After receiving the request, the central processing system locks the seat position selected by the reader and starts timing. The seat uses a gravity sensor to determine whether someone is using it. When no one has used the time, the reader reservation system releases the seat again;

5. When the seat is in use, the reader reservation system will show that the seat is occupied;

6. When the reader leaves the seat, the gravity sensor sends an empty seat information to the central processing system, and the central processing system starts to calculate the empty seat time. When the empty seat time meets the set time, the reader reservation system releases the seat again;

7. When the unused seat is moved, the seat tracking device sends a signal to the central processing system, and the seat becomes unusable at the same time. After the central processing system receives the signal, it notifies the administrator system, and the administrator receives the signal. After information, go to the scene for processing; the reader reservation system still shows that the seat is not occupied;

8. The administrator goes to the scene to restore the seat and use the remote control device to restore the seat to a usable state.
