Abstract
Automatic security warning device for railways, essentially characterized by being integrated in a set formed by two units, one of them emitting and another receiving, the first comprising a direct current power supply, a variable timer, adjustable within time limits convenient, automatic connection and disconnection of the power supply of a pulse generator of variable frequency, in positive sign, and an amplifier that reinforces said impulses, sending them through an antenna.
