Description

ABSTRACT

Accident ration is increasing through every year so that analysis about the accident is very essential, normally in Flights, the black box will be present to analyze every parameter of flight, if there any accident occurs then they will first search for black box, which will have every parameter log about the flight, which gets crashed. It is implemented in Raspberry Pi at low cost. Which also sent to the transport department through MQTT protocol. Which is transmitted as quick speed when compared to HTTP protocol since MQTT protocol is lightweight protocol.

BLOCK DIAGRAM

BLOCK DIAGRAM DESCRIPTION

In the above block diagram, Robotic car is connected to the Raspberry Pi in the GPIO pins, then IR sensor is connected to the car in the wheel part to measure the speed of the car as in a simple manner, then Alcohol sensor is also connected in the car to monitor the driver whether he consumed alcohol or not.

 

PROJECT DESCRIPTION

This Raspberry Pi system which monitors the car speed, alcohol detection and also transmit those data logs through MQTT protocol, so that if there any accident happens it is identified by studying the catalogs which we obtained from the MQTT protocol, which the MQTT is lightweight protocol, consist three layers, Publisher, Broker and Subscriber. Even if the Subscriber is connecte3d in the centralized node called Broker, data get stored in that node and it sent to the subscriber when the subscriber comes into the network. Main advantage of MQTT is that is lightweight protocol, even in low internet speed it can send the data.

 

HARDWARE REQUIRED

• Raspberry Pi
• Power Adapter
• HDMI to VGA converter (optional, when connecting to Monitor)
• MCP3008 (ADC IC)
• L293D (Driver IC)
• Gas sensor

 

SOFTWARE REQUIRED

• SD Card Formatter
• Win32 Disk Imager (or) Etcher
• MY MQTT android app (optional for seeing data logs in android mobile)

 

LIBRARIES USED

• Rpi.GPIO as GPIO (To access GPIO Pins of Raspberry Pi)
• Time library (For Delay functions)
• Paho-MQTT

 

CONCLUSION

By transmitting Data logs through MQTT protocol we can send whole data logs whenever we connected to the network by subscribing the MQTT. It can also be viewed in System by executing subscriber program as well as in android app called MY MQTT to view the data logs.
