Automatic Library Book Management System

Hello Everyone Myself Mohit and i have created this Automatic Library Book Management System...

Description:-

Hello Everyone Myself Mohit and i have created this Automatic Library Book Management System Project. Let me first tell you how this Project Play an Important role in Real World as you all aware about the Current Pandemic Situation and now colleges/schools have been Re-opened it is important to maintain Social Distancing. Till Now in Some Colleges or schools Book are being Issued to Student Manually by using barcode Reader and excel sheet. All of the book and Student Library ID Card have barcode. To Issue book student have to give there book to Library teacher along with there Library ID Card and the Library teacher issue the book by scanning the barcode on book and student library ID card. If Teacher/Student is Sick then there might be chances that germs will be transferred to the Book or Library card. My project help in maintaining Social Distancing and also reduce close contact between people.

Through this project student can easily Issue/Return book they just have to wave there hand on the right/left side(IR sensors) of the project and place there book and library ID card then the book will be issue/Return.

Each Book and Library ID card are being provided with the barcode.

Instead of barcode reader in this project i'm using a camera and using open CV to detect the barcode value.

Book and Libary ID card Details are Stored in an Remote MySql Database.

I have also Created an App and a Website using python-Flask and Hosted it online on Heroku for free.

Student can see there details on website by entering there University Enrollment Number or Library ID Card Barcode Number.

Advantage of Website in Worst case scenario if Hardware stopped working for some reason then the Teacher can manually issue/return book to student.

App is created Using MIT app inventor can only access by Library person for Security purpose So that no one to who the book belong  not steal the book from library. Will explain it in more detail below.

Thing you should know about the Projects:-

  • Each book can be issue to student for 14 Days. If student exceed the the return date then he will be charge 2 Rs per Day (this value can be change in the code).
  • Student can only issue  5 Books if they try to issue more than 5 books system will display or say that "You cannot issue Books More than 5". We can increase the number of book to issue but it will make the code lengthy as i have created the code with simple logic which is more effective and less buggy(error).
  • Student can only Return/Reissue book after 7 days before that they won't be able to do that

Library Book Management System

As it's a prototype that's why i have created it in cardboard but in practical world a 3-D printed box or sheet metal box can be created.

Hardware Used

Raspberry pi 3 B+ Model, IR Sensors, Raspberry Pi TFT Display, Usb web-cam, usb sound card, Transformer, capacitor, diode, resistor,7805 voltage rectifier, LED, power adaptor ,  jumper wire, pcb, box, LED Light, Usb Speaker

Software Used

Python, Open-cv, Pyzbar library, gtts library, Python-Flask, mysql, MIT App Inventor(app), PHP, pysimplegui

Hardware and Software Selection

Here i have used raspberry pi 3 b+ model which has 1.4ghz processor with built-in wifi and bluetooth functionality. In this project  i have opt-out for raspberry because the need for high processing power also it's easy to use, cheaper and it support usb web camera.

Raspberry pi also provide Gpio pins through that i was able to interface IR Sensor easily.

To Make the User GUI (Graphical user interface ) i have used pysimplegui library through this i was able to display text (instructions) on TFT Display.

Instead of normal LCD i have used TFT Display (3.5 inch) to make the project more user friendly.

Power supply -

Created a Ac to Dc full bridge rectifer power supply which output 12v and 5v. This giving power to our both IR sensor and LED Light(12v).

To giving power to raspberry pi i have used 5v, 3A Adaptor and for Speaker i have used a anothter usb adaptor. i have connected all the input power  to a single power cable.

We two option to read(detect) barcode of books or student ID card either we go for normal usb Barcode Reader or Usb web-camera. Here i have used Usb Web- camera for detecting barcode instead of normal barcode reader because it's cheaper as compare to barcode reader.

Software-

website which you see here( https:/ /librarybookmanager.herokuapp.com/ ) is being created using python-flask because through this i was able to use mysql connector library which allow me to connect to my database and also issue/return/re-issue book manaully or make changes in database.

App-

App will play an important role as it prevents the books from getting stolen. As the system is automatic that why there might chances that some students try to take books without issuing.

so to prevent this the library person will sit at the exit door of the library along with the mobile application and by scanning student the library person will able to see all the student detail like how many books issued to them or which are those books and there total fine.

Circuit Diagram Image

Library Book Management System Circuit

In hardware side there are two IR sensor which are connected to Raspberry pi gpio. Right sensor output pin is connected to raspberry pi gpio pin 20 and Left side Sensor output pin is connected to Raspberry pi gpio pin 21.

VCC of both Sensors are connected to the 5v output of the power supply and ground to power supply ground.

Raspberry pi Gnd pin also connected to power supply ground side.

i have given seperate power to raspberry pi using 5v 3a adaptor and speaker have been connected on seperate usb adaptor but all the power input are connected to a single power cord (plug).

Speakers are connected to raspberry pi through Sound card so that we hear loud sound it boost volume of the speaker.

USB web-camera is connected to the usb port of the raspeberry pi.

LED Light is used to give our usb web camera better lighting so that the camera was able to get clear view of the barcode.

LED Light positive side is connected to power supply 12v output and ground is connected to power supply ground.
