Monitoring and transmission of heavy vehicle parameters using fixed cellular terminal

At present any consignment carried by a vehicle has to travel incommunicado till it reaches the destination. So, both the fleet owner and the persons sending or procuring the consignment have to sit keeping their fingers crossed till the fleet arrives. To track the path of the vehicle and to monitor the various parameters like fuel consumption, kilometers covered and the amount of load in the vehicle an intelligent device would come handy to solve the problem for the fleet operators and the clients. This paper aims at designing an intelligent device, which has two parts: the transmitter and the receiver. The transmitter is set up in the truck and it consists of a microcontroller to which the GPS and the GSM modem are connected. The analog signals from the transducers, which are used to detect the amount of load and the fuel in the truck, are sent to the microcontroller. The microcontroller acquires the position of the truck from the GPS and sends it to the receiver along with the analog values, through the GSM modem using SMS. The receiver consists of a computer to which a GSM modem is connected by its serial port. The SMS is received by the GSM modem and is sent to the computer, which makes use of a map plotting software to plot the position of the truck along with its parameters.
