Description
Technical field
The utility model relates to magnetic flux density vector measurement mechanism, particularly a kind of magnetic flux density vector measurement mechanism based on Hall effect.
Background technology
Magnetic field is an important physical quantity, and in space, the distribution in usual magnetic field is uneven in its distribution, and because magnetic field is vector, thus the size and Orientation of each point is not identical.That scientific research or technological development all have important physical significance to the measurement in magnetic field, mainly use mT meter and Hall magnetic field tester to complete the measurement in magnetic field in current experiment, these two kinds of instruments can not meet the measurement demand to this vector of magnetic field.Nowadays the size of magnetic field in the magnetic field in a direction can only be determined and describe to the Hall effect magnetic field tester instrument in laboratory teaching and mT meter.Using existing instrument, if in order to measure the magnetic induction density of a bit, needing, at spatial rotation Hall plate or sensor, to find maximum reading, thus obtain measured value.But often can not obtain the data of magnetic direction, be impossible in fact with the direction that the method makes Hall plate or Hall element aim at magnetic flux density vector completely obviously, therefore current method has certain limitation in actual measurement simultaneously.
For the test of space magnetic field, do not have at present to test the instrument that magnetic field size can test again magnetic direction, this is any magnetic field of solution space to us, is familiar with objective Distribution of Magnetic Field situation not enough.
Open (bulletin) number: the CN2566281 of patent, discloses a kind of three-dimensional digital Hall magnetic field measuring device, contains based on the magnetic field measurement circuit of three-dimensional Hall chip, power supply and LCD MODULE in measuring instrument.Complex structure, cost is high.
Open (bulletin) number: the CN203520718U of patent, disclose a kind of space magnetic field measuring instrument, can locate implementation space, but use a Hall plate, measure the size of magnetic induction density by rotating Hall plate, this way measurement result is inaccurate.
Utility model content
The utility model provides a kind of magnetic flux density vector measurement mechanism based on Hall effect, and this device can test the instrument that magnetic field size can test again magnetic direction.
A kind of magnetic flux density vector measurement mechanism based on Hall effect that the utility model provides comprises: vector feeler lever, " one " font Hall plate pilot hole, " ten " font Hall plate pilot hole, x-axis is to measurement zone, y-axis is to measurement zone, z-axis is to measurement zone, x-axis is to mobile scale, y-axis is to mobile scale, z-axis is to mobile scale and base, described x-axis is to mobile scale, y-axis is installed on base to mobile scale and z-axis to mobile scale, and be combined into three-dimensional frame, realize the space orientation to sensor, wherein, x-axis has rack and pinion gearing below mobile scale, drive x-axis to mobile scale transverse shifting on base, y-axis has rack and pinion drive after mobile scale, drives y-axis to move up and down on base to mobile scale, z-axis has rack and pinion gearing to mobile scale side, drives z-axis movable on base to mobile scale, vector feeler lever is fixed on the front end of z-axis to mobile scale, and vector feeler lever is the plastic bar that lightweight has intensity, " one " font Hall plate pilot hole and " ten " font Hall plate pilot hole are located on vector feeler lever.
The beneficial effects of the utility model are embodied in:
The connection of existing feeler lever structure and feeler lever and Hall plate is improved, three components in magnetic field can be measured at a point.Use this device, only need Hall plate to go out three components in X, Y, Z tri-measurement of bearing, then just can synthesize the size obtaining magnetic induction density component, and the direction of magnetic induction density.Due to without artificial judgement, the precision of outcome measurement depends on the measuring accuracy of instrument completely.Existing instrument, by rotating Hall plate, is merely able to the approximate value measuring magnetic induction density, moreover accurately can not determines direction; Because Hall plate is fixed on feeler lever inactive, often takeing for magnetic induction density after experiment is scalar.After improvement, by the size of the measurement synthesis magnetic flux density vector of component, the direction of calculated magnetic induction strength vector, has therefore also greatly enriched the content of experiment.The utility model will be widely used to the measurement result of magnetic flux density vector in industrial design.
