How switch-type Hall sensors measure the speed or number of revolutions:

A piece of magnetic steel is glued on the edge of the disc of non-magnetic material, and the Hall sensor is placed near the edge of the disc. When the disc rotates once, the Hall sensor outputs a pulse, so that the number of revolutions (counter) can be measured. Into the frequency meter, the speed can be measured.

If the switch-type Hall sensor is regularly arranged on the track according to the predetermined position, when the permanent magnet mounted on the moving vehicle passes through it, the pulse signal can be measured from the measuring circuit. According to the distribution of the pulse signal, the speed of the vehicle can be measured.
