Smart Fuel Theft Detector Supervisor: Dr. Samer Mayaleh Prepared by: Amjad Rabaya Adham Sawafta An-Najah National University Faculty of Engineering شكر وتقدير OUTLINE Review Limitations & Challenges Solution methods Used Elements Measuring & Theft Hardware Tutorial Database The End OUTLINE Review Limitations & Challenges Solution methods Used Elements Measuring & Theft Hardware Tutorial Database The End Review What is smart fuel theft detector ? Why to use smart fuel theft detector ? Review What is Theft? The fuel is being stolen from the vehicle's tank through withdrawing using a pipe. The tank is filled with amount less than written in the bill. Review Review Why to use smart fuel theft detector ? Helps the companies to monitor and identify exactly its fuel consumption periodically and in real-time. Prevents fuel theft from the vehicles tanks. Helps identifying the fuel thief (the driver or other people). OUTLINE Review Limitations & Challenges Solution methods Used Elements Measuring & Theft Hardware Tutorial Database The End Limitations & Challenges The flammability of the fuel Accurate and Safe Isolation Limitations & Challenges Dynamic motion of the fuel Multi Readings per Second OUTLINE Review Limitations & Challenges Solution methods Used Elements Measuring & Theft Hardware Tutorial Database The End Solutions Ultrasonic Sensor Flammability no electrical connection between the sensor and the tank. Spark-Free device Accurately closed Tank Small size, no need to make large holes in the tank. Dimension: 45mm x 20mm x 15mm Solutions Dynamic motion of the fuel Averaging and filtration (100 readings) we did a simple averaging for the values because the normal decreasing of the fuel level is small and so no needed to make a complicated filtering. Solutions Slope of the roads Using LSM303DLH sensor to Determine the slope. Find the actual level considering the slope of the road. It is fitted outside the tank OUTLINE Review Limitations & Challenges Solution methods Used Elements Measuring & Theft Hardware Tutorial Database The End Used Devices Ultrasonic Sensor (HC-SR04) Slope Sensor (LSM303DLH) Microcontroller (PIC16f877) GPRS Module (not available!) Fitted on the tank directly Connected wired to the controller Used Devices Ultrasonic Sensor Ultrasonic Principle of Work Transmitter Receiver Some Object Output: Time of Flight (uSec) Trigger Echo 5 volt 10 uSec PWM depends on the distance Used Devices Ultrasonic Sensor Filters the readings (50 to 1) Converts the readings to volume Theft detection Pass readings to GPRS module Used Devices Microcontroller Converts from PWM time to digital volume PWM signal Digital Time (uSec) Volume signal (Liter) Used Devices Microcontroller Filtering and averaging i.e. Microcontroller is faster than the sensor 3 … 9 10 1 2 1 Give one reading Used Devices Microcontroller Check For Fuel Theft NO YES Used Devices Microcontroller Receives readings from the microcontroller Sends it to the company for further processing.

Flat-Road & Moving Impossible Theft. Tilted-Road & Stopping Probable Theft! Tilted-Road & Moving Impossible Theft. Theft Detecting The principle of Theft-Detecting is based on the Consumption Rate and the Fuel Change of the vehicle. Fuel Change ≥ Consumption Rate Fuel Change ≤ Consumption Rate THEFT Normal Case Study 50-passengers-bus   OUTLINE Review Limitations & Challenges Solution methods Used Elements Measuring & Theft Hardware Tutorial Database The End Hardware Tutorial OUTLINE Review Limitations & Challenges Solution methods Used Elements Measuring & Theft Hardware Tutorial Database The End Database THANKs For Listening image2.jpeg image3.png image4.png image5.jpeg image6.jpeg image7.png image8.jpeg image9.jpeg image10.gif image11.jpeg image12.png image13.png image14.jpeg image15.jpeg image16.jpeg image17.jpeg image18.png image19.jpeg image20.jpeg image21.jpeg image22.jpeg image23.jpeg image24.jpeg image25.jpeg image26.png image27.jpeg image28.jpeg image29.png image30.jpeg image31.jpeg image32.jpeg image33.jpeg image34.jpeg image35.jpeg image36.gif image37.png image38.emf image39.png image40.jpeg image41.jpeg image42.png image43.png /docProps/thumbnail.jpeg
