Embodiment 1
[0095] Embodiment 1, a sensor with multiple magnetic blocks evenly distributed in the housing
[0096] Such as figure 1 , 3 , 4. The sensor in this embodiment includes a sensing element connected in sequence, a booster model processor 21, a digital-to-analog converter 27 and an operational amplifier 28;
[0097] [1] The sensing element is an element that converts the rotational motion of the rotating disk 1 into a rectangular wave signal output;
[0098] The concave surfaces of an annular groove rotating disk 1 and an annular groove fixing disk 40 are opposite, and the size of the annular groove rotating disk 1 and the annular groove fixing disk 40 is just enough to make the annular groove fixing disk 40 fit in the ring. In the annular groove of the groove rotating disk 1, two disks are synthesized into a fitting inner hollow shell that can rotate relatively, and the concave surfaces of the two disks are sandwiched into a hollow ring 41; the annular groove rotating disk 1 at...
Embodiment 2
[0112] Embodiment 2, high-density sensor with multiple magnetic blocks evenly distributed in the housing
[0113] Such as figure 2 , 3 , 4, the annular groove rotating disk 1 surface diameter in the hollow ring 41 is 10.0 centimeters, establishes 40 permanent magnet pieces 2 in the annular groove rotating disk 1, and the diameter of 40 permanent magnet pieces 2 is respectively 0.6 centimetre, and the magnetic flux is 146---279(B·H)max / KJ·m -3 one of the values in . Hall 3 keeps a distance of 0.2 cm from each permanent magnet 2 in the rotating state, so that when each rotating permanent magnet 2 passes through Hall 3, Hall 3 can generate a corresponding rectangular wave electric signal output. The structures of other rotating disk 1, permanent magnet block 2, and Hall 3 are the same as those in embodiment 1.
Embodiment 3
[0114] Embodiment 3, a sensor with multiple magnetic blocks evenly distributed in the casing with a specific circuit
[0115] Such as figure 1 , 3 , 5. The sensor in this embodiment includes a sensing element connected in sequence, a booster model processor 21, a digital-to-analog converter 27 and an operational amplifier 28;
[0116] [1] The Hall 3 in the sensing element is UGN3075; the structure of other elements and elements in the sensing element is the same as that in Embodiment 1;
[0117] [2] The auxiliary model processor 21 selects the single-chip microcomputer 31 to complete all functions, and the single-chip microcomputer 31 selects AT89S52. That is, the AT89S52 single-chip microcomputer 31 completes all functions of the analog-to-digital conversion and the speed calculator 24 , the booster model memory 25 and the booster model calculator 26 .
[0118] [3] The digital-to-analog converter 27 selects ADC-C8E.
[0119] [4] OF-17F is selected as the operational ampli...
