GSM-CONTROLLED NNPC TRUCK (SMART ELECTRIC VEHICLE)

GSM-CONTROLLED NNPC TRUCK (SMART ELECTRIC VEHICLE) The most innovative project in the 2012 National Science and Technology Exhibition held for all the tertiary institutions in Nigeria – Invented by Prince Nwankwo

A. Project Overview: The GSM-Controlled NNPC Truck is a groundbreaking prototype that demonstrates how mobile telephony and embedded systems can be leveraged to control remote vehicles. Recognized as the Most Innovative Project during the prestigious 2012 National Science and Technology Exhibition held in Abuja, Nigeria, this invention combines mobility, wireless communication, and automation to simulate the real-time control of an NNPC fuel tanker truck. The system enables users to control the truck’s movement; including forward and reverse driving, using a mobile phone. With integrated obstacle detection and avoidance capabilities, this prototype showcases advanced safety and automation features suitable for industrial, defense, and logistics applications.
B. Innovation Description: The core technology behind this invention is DTMF (Dual Tone Multi-Frequency) communication, widely available in mobile phones, in combination with Bluetooth connectivity. The system is designed to operate within a 10-metre range, allowing full control of the truck remotely via a paired mobile device.
C. Key components and functionalities include:
- Bluetooth Module: Facilitates wireless communication between the mobile phone and the truck.
- DTMF Decoder (MT8870): Interprets keypad tones from the phone and converts them into digital signals.
- Microcontroller (AT89C51): Processes commands from the DTMF decoder and controls the truck’s functions accordingly.
- Relay Modules: Used to drive electric motors that power the truck’s movement (forward, reverse, stop, etc.).
- BC337 Transistors: Act as buffers between the microcontroller and the relays.
- Ultrasonic and Infrared Sensors: Enable real-time obstacle detection and avoidance to enhance navigation safety.

When a user presses the control key on their mobile phone, the tone is transmitted via Bluetooth to the onboard DTMF decoder, which converts it into a binary signal. The microcontroller processes this signal and responds by activating the appropriate relay, thereby controlling the motion of the truck.
D. Key Features
