ELECTRONIC LOCKER SYSTEM

[attachment=15918]


CHAPTER I MAIN SECTION

1.1 Overview
The project design Electronic Locker System functionally comprises of a hardware and a software in its assembly. The former is the construction of locker units that operates electronically through the integration of electronic devices such as a barcode reader and magnetic actuators that innovates the key-operated lockers into a much modern type. In addition, a software system is precisely analyzed and designed to come up with effective system for the operators as well as the users in which is installed in control of a host computer.
This project as described in the composition of its parts will only work and assures to give its greater performance when all of its components are surely connected. It consolidates a computerized system wherein the provider or operator manages a database containing a profile and all other necessary information about the users or customers. The user whom is recognized by the system after swiping an identification card on the barcode reader and entering the right pin codes issued have the sole access to lock and unlock a slot in the locker that offers a truly security solution.
Security pertains to freedom from danger, as it is relevant in many institutions especially in the maintenance and proper care of their facilities. One of the features of this proposed product is the consolidation of a computerized system. Its database contains all the necessary information about the customer as required by the provider or operator. Only the user whom is recognize by the system can use and have a sole access on the designated lockers provided with pin codes. It aims to attain convenience and orderliness.

1.2 Definition
The construction of locker units operates electronically through the integration of electronic devices such as a barcode reader and magnetic actuators, etc. Which solely controlled by the software system with its specialized database intentionally done to be use and access by the College of Engineering of Tarlac State University, wherein the provider or operator manages a database containing a profile and all other necessary information about the users or customers through the use of a host computer. The user whom is recognized by the system after swiping an identification card on the barcode reader and entering the right pin codes issued have the sole access to lock and unlock a slot in the locker that offers a truly security solution.

1.2.1 Statement of the Problem
The purpose of this project design is to modernize and upgrade the utilization and system of existing lockers. Specifically, the design study sought answers to the following questions:

1. Do you want a personal locker in keeping your heavy and bulky things when going to school instead of bringing them daily?

2. Does the key - operated locker give the user privacy in using his/her locker?

3. Knowing that the lockers are on a rent basis, are you willing to pay the whole month if you were only to use it for 1 week?

1.2.2 Goal
The goal of the design project is to eliminate the use of key locks and number locks in the existing lockers and replace them with an electronic type locks for ease of use and security reasons. With the use of identification standard procedures and public accessibility of these existing locker systems, the study aims to make the system electronically based to justify only the sole member or students of College of Engineering, it only means that non-engineering course can’t access the system. Moreover, with the good analysis of implementing the prepaid form to use and avail it in the way of the users need, to make it more convenient and affordable to use.

Addressing Parallel Ports

Port
A port contains a set of signal lines that the CPU sends or receives data with other components. We use ports to communicate via modem, printer, keyboard, mouse etc. In signaling, open signals are "1" and close signals are "0" so it is like binary system. A parallel port sends 8 bits and receives 5 bits at a time. The serial port RS-232 is a multidirectional that sends and receives 1 bit at a time.
