Microcontroller-Based Auto Lock Ignition System for Vehicle Overload Prevention

New technologies are being developed for more efficient overload screening and enforcement. Weigh-in-Motion (WIM) technologies allow trucks to be weighed in the traffic flow, without any disruption to operations. Much progress has been made recently to improve and implement Load cell based overload detection systems, which can contribute to safer and more efficient operation of trucks. In this work, we are developing an Auto Lock ignition System. The input for the system is from Load cell or any other mechanism. The controller keeps looking for the output from these sensors. If there are any traces of over load above the set limit, then the system will lock the Engine. In our work Microcontroller based Monitoring system monitors the vehicle overload. When the reference voltage from load cell exceeds the set limit the controller cut off the power supply to spark plug thus it stops the ignition in engine.
