Method for detecting the speed and direction using the magnetic field dependent on the realization of this procedure sensors.

摘要

METHOD FOR DETECTION OF SPEED AND ROTATION THROUGH SENSORS DEPENDENT MAGNETIC FIELD AND SYSTEM implementing this process, whereby said sensors (2, 3, 4, 5) are positioned one after another IN A FIELD MAGNETIC ROTATING PERIPHERAL AND ADDRESS IN WHICH TAKE sensor signals (S1, S2, S3, S4) to evaluate them in a computer unit (18). SE PROPOSES A method and system board (1) with which the sensor signals (S1, S2, S3, S4) can be evaluated easily and inexpensively. THEREFOR, four sensors (2, 3, 4, 5) of electric resistances DEPENDENT MAGNETIC FIELD (6, 9, 10, 13), with respective second electric resistances (7, 8, 11, 12) are provided on a divisor TENSION (15, 16, 20, 21) and four ELECTRONIC CIRCUITS comparators (23, 24, 25, 26). Comparators (23, 24, 25, 26) CIRCUITS generated from the signals of the sensors (S1, S2, S3, S4) Four measurement signals (M1, M2, M3, M4) REDUNDANT offset in phase, transmitted to the computer unit (18) for detecting the speed and direction of rotation.
