Security system for trucks in mines using radio frequency modules. The trucks carry a device in the back and the miners in their helmets. Workers are warned of the degree of danger according to their proximity to the trucks. There are several alarm types that are fully configurable by zones: vibration, siren or alarm in headphones. In addition, you can locate the tracks and workers, stop trucks or indicate breakdown or repair. The person in charge of the mine uses this application to configure the trucks and protect her staff.
