A Public Transport Fare Monitoring System Using Arduino

Introduction

Public transport refers to shared passenger transportation services like bus, trains, metro, trolleybus etc. There are many challenges that are faced by passengers while using public transportation. The main problem while using public transportation is the fare rate.

So, In this project we have designed such a system where passenger themselves can monitor the fair based upon the distance traveled by them. If this system is installed in any public transportation then passenger should enroll their finger in the fingerprint sensor while entering the vehicle and should enroll it back while leaving the vehicle. When we enroll the finger while leaving the vehicle the display unit in the system shows the total distance traveled and the total fair to be charged based upon that distance traveled. Passenger should not negotiate with bus unit for the fair. We can also further improvement in this project by integrating online payment system in this project.

PCB MANUFACTURER

The pcb of this project is manufactured by JLCPCB. The reasons to choose JLCPCB for pcb manufacturing are:

• Higher Quality
• Lower Cost
• Faster Delivery

JLCPCB are also sponsor of this project. JLCPCB (Shenzhen JLC Electronics Co., Ltd.), is the largest PCB prototype enterprise in China and a high-tech manufacturer specializing in quick PCB prototype and small-batch PCB production. You can order a minimum of 5 PCBs for just $2. To get the PCB manufactured, upload the gerber file you downloaded in the last step. Upload the.zip file or you can also drag and drop the gerber files. After uploading the zip file, you’ll see a success message at the bottom if the file is successfully uploaded. You can review the PCB in the Gerber viewer to make sure everything is good. You can view both top and bottom of the PCB. After making sure the PCB looks good, you can now place the order at a reasonable price. You can order 5 PCBs for just $2 plus shipping. To place the order, click on “SAVE TO CART” button. My PCBs took 5 days to get manufactured and arrived within 20 days using standard registered post delivery option. There are fast delivery options also available. PCBs were well packed and the quality was really good. JLCPCB is now offering SMT assembly service that too at a very reasonable price and after trying it I must say that they are doing excellent work and their craftsmanship is comparable to any other commercial PCB manufacturing and assembly service all over the world.

Objectives

The main objectives of this project are :

• To facilitate passenger know their exact fare according to the distance traveled by them.
• To facilitate the owner of the bus to know the exact data about the number of passenger traveled and total collected amount.

Block Diagram

The Block Diagram of the project is explained in following blocks

Working Principle

It has very simple working principle. When the new passenger enters the public vehicle, He/she should place their thumb finger in the fingerprint sensor. After they place the finger, the device make new registration and provide unique id to that person. At the time of the registration the device also record the pulse generated from hall effect sensor as a initial value. Now when the same person reaches the destination, He/she must place the same finger in the device. when the fingerprint sensor finds the registered finger it understands that person has reached the destination. At this time the device set the final pulse and calculate the distance traveled by passenger by generating the difference between the final pulse and the initial pulse. We can easily multiply the distance with any constant value to generate the fair as rules and regulation. If you have any discount card like(student card, old aged card ), you can press the discount button available in the device to achieve the available discount.

The owner of the bus can also calculate the total passenger and total amount of money collected at the end of the day or at the end of each tip by pressing the reset button. After pressing the reset button all the data will be erased from the device and will be saved in sd card for further data analysis.

This device helps the owner of the bus to know the exact idea about the total money collected from the bus.

Circuit Diagram

The Circuit diagram of the project is as shown in the figure below :

There are two arduino’s used in our project due to lack of user defined pins. The first arduino communicates with RTC, fingerprint sensor, Buzzer, Leds, push button and TFT display and the second Arduino communicates with SD card module and hall effect sensor.

There is I2C communication between two arduino’s.
