1. A system for monitoring personal mobility vehicles in urban environments comprising a double magnetic coil (1) disposed at an area of personal mobility vehicle traffic, and connected to an oscillator circuit (2); where the assembly of double magnetic coil (1) and oscillator circuit (2) is in turn connected to a phase-locked loop (3); a signal conditioning circuit (4) connected to the output of the phase-locked loop (3) and a signal processor (5);
wherein the system is characterised in that
the double magnetic coil (1) has maximum measurements of 0.5×0.4 metres, with a number of turns between 5 and 8 and an oscillation frequency between 400 kHz and 800 kHz;
and in that the signal processor (5) is configured to calculate the temporal variation in voltage (V(t)) and its derivative (V′(t)) produced in the phase-locked loop (3) and due to a variation in the oscillation frequency of the double magnetic coil (1) when at least one personal mobility vehicle passes said double magnetic coil (1); and to establish, based on the calculation of the temporal variation in voltage (V(t)) and its derivative (V′(t)), the type, speed, direction of travel and length of the personal mobility vehicle that has generated the variation in the oscillation frequency of the double magnetic coil (1).
