Detailed description of the invention
The structure of the present invention is as Figure 1-4: a kind of based on Wiegand effect rotate from magneto-electric multi-turn absolute value of powering
Encoder, including housing 5, is provided with fixed mount 2 in housing 5, and two blocks of magnet steel 1 are fixed on fixed mount 2, fixed mount 2 and rotating shaft 3
Connecting, circuit board 4 is positioned at above magnet steel 1.Two blocks of described magnet steel 1 are thickness and magnetize, and the N magnetic pole of a piece of magnet steel 1 is upwards put
Putting, the S magnetic pole of another sheet magnet steel 1 is upwards placed.
The Wiegand sensor 6 of the present invention, interface circuit 11 are positioned at the one side of circuit board 4, Hall angular position sensor 7,
Fpga chip 8, ferroelectric memory 9, single-chip microcomputer 10 are positioned at the another side of circuit board 4.
Fpga chip 8 can be selected for ACTEL A3PN010 or other similar chips；Single-chip microcomputer 10 can be selected for ATMEL
MEGA88PA or other similar single-chip microcomputers.
Rectification filtering voltage stabilizing circuit and the shaping circuit being connected with Wiegand sensor 6 is included on the circuit board 4 of the present invention, whole
Shape circuit is connected with fpga chip 8 and ferroelectric memory 9 respectively；The power supply of rectification filtering voltage stabilizing circuit export shaping circuit,
Fpga chip 8 and ferroelectric memory 9；Ferroelectric memory 9 is connected with machine 10, single-chip microcomputer 10 respectively with respectively with Hall angle position
Sensor 7 and interface circuit 11 connect；Second mu balanced circuit respectively with ferroelectric memory 9, single-chip microcomputer 10, interface circuit 11 and suddenly
You connect by angular position sensor 7.
The operation principle of the present invention is as follows:
Wiegand sensor 6 is the magneto-dependent sensor utilizing Wiegand effect to develop, and Wiegand sensor 6 is fixed on circuit
On plate 4, the distance suitable distance of magnet steel 1, different according to Wiegand sensor characteristic and magnet steel intensity, need micro-between 1-20mm
Adjusting, when rotating shaft 3 rotates and drives magnet steel 1 to rotate, the alternating magnetic field outside Wiegand sensor 6 will change, when Wiegand senses
When on B alloy wire within device 6, effect has suitable external magnetic field, inner core magnetization saltus step, detection coil will export induced potential arteries and veins
Punching, even if also can produce reliable signal in the case of slowly rotating close to zero, rotating shaft 3 often rotates a circle, and Wiegand senses
Exportable two pulse signals of device 6, different according to the phase place of pulse signal, distinguishable go out the direction that rotates of rotating shaft 3.This pulse warp
After over commutation, filtering, voltage stabilizing, on the one hand out-put supply 1 does power supply supply, on the other hand this arteries and veins to the components and parts on circuit board 4
Punching, after shaping circuit, accesses fpga chip 8, indicates as encoder direction of rotation, and fpga chip 8 judges according to pulse
The direction of rotation of rotating shaft, counts rotating shaft 3 rotating cycle in FeRAM memory chip 9.
Hall angular position sensor 7 is positioned in the magnetic circuit that magnet steel 1 is formed, and it can be by the magnetic parallel with chip surface
, inducing the absolute angular position in the range of 0-360 degree, Hall angular position sensor chip 7 and single-chip microcomputer 10 are carried out even
Connect.Hall angular position sensor 7 is positioned at the ad-hoc location of circuit board and (according to chip type selecting difference, may be perpendicular to Wiegand and pass
Sensor 6 or be parallel to Wiegand sensor 6, when Hall angular position sensor 7 exports 0 degree when, Wiegand sensor 6 is just
A pulse can be exported, increase or reduce counting as rotating cycle and be used.
After external power source connected by encoder, the second mu balanced circuit work, out-put supply 2, single-chip microcomputer 10 is started working, and reads
Take the number of turns recorded in storage chip 9, and read the angle value of Hall angular position sensor chip 7, by calculating, can obtain
Take the absolute value of rotating shaft 3 mechanical location, through interface circuit 11, accept the access of external communication circuit.
