Abstract
This invention discloses a acceleration and displacement sensor, which comprises one position signal generator, one signal detector, computation device and one power supply device and one inductive rollers, wherein, the position signal generator and inductance rollers form one sealed space to limit sliding path of the rollers, which is characterized by the following: the position signal generator is composed of several inductance terminals parallel distributed with each terminal set with certain position signals; the inductance roller is contacted to the inductance terminals of relative positions to send special position signals and computation device.
Description
Technical field
The present invention relates to a kind of acceleration and displacement sensor, more particularly, refer to that especially a kind of induction terminal that utilizes cooperates the induction ball to obtain the inductor of absolute precise displacement influence value and displacement acceleration.
Background technology
As shown in Figure 5, " displacement sensing device " referenced patent (hereafter is a referenced patent) of publishing for " Nihon University ".As seen from the figure, utilize hollow inductive coil group 60 to cooperate probe 70 with taper cross-section structure, by the inductance frequency change that slippage produced of probe 70 in coil groups 60, pass through signal amplifier 61, phase-shift circuit 62, frequency departure inductor 63 and displacement counter 64 again, just can obtain required " micron order " even the shift value of " nanoscale ".
In fact, members such as this signal amplifier 61, phase-shift circuit 62, frequency departure inductor 63 and displacement counter 64, according to present scientific and technological level, can be with one " microprocessor " integration processing in addition, just, this referenced patent is the easy identification of asking in the patented claim explanation, just disassembles explaination; But obscuring and make every effort to simple and clear principle in the explanation all is referred to as " signal detects and arithmetic unit " below.
In the open explanation of this referenced patent, emphasize that again and again its inductive coil 60 can eliminate interference phenomenon (being the interference of electromagnetic field) because of coil magnetic field will inevitably cause by rational arrangement; Certainly, with regard in theory, it might overcome so-called coil magnetic field really and disturb, but with regard to practice, no matter be coil specification, material purity, power supply power, stability of power supply, coil arrangement precision and even signal detects and the binding of arithmetic unit, all might cause the interference of some coil magnetic fields, in other words, this device is after reality is produced in batches, and its detecting precision and degree of stability allow the people become suspicious really unavoidably.
Summary of the invention
The purpose of this invention is to provide accurately a kind of and stably reach the expection inductive effects acceleration and displacement sensor.
In order to realize this purpose, the present invention is on concrete structure, mainly adopted a position signal generator, a signal detects and arithmetic unit, a power supply device and an induction ball, wherein, this position signal generator and induction ball form an enclosure space, the sliding path of restriction and guiding induction ball; And this position signal generator is made up of countless induction terminals according to axial array, and each induction terminal all is configured to have certain location signal value, the induction ball then contacts with the induction terminal of this correspondence position according to the present position, at any time send ad-hoc location signal value and give that signal detects and arithmetic unit, so when the induction ball because of stressed during according to axial slip, signal detects and arithmetic unit just can detect the displacement union according to the diverse location signal value in the relative time and goes out the displacement acceleration.Because utilize the induction terminal to cooperate the induction ball to replace inductive coil and probe, thus removed the possibility of so-called magnetic interference phenomenon fully, can be accurately and stably reach the expection inductive effects, have industry applications and practicality.

Embodiment
Below, in conjunction with the accompanying drawings, the invention will be further described by specific embodiment.
As shown in Figure 1, structural representation for a preferred embodiment of the present invention, wherein inductor 10 comprises a position signal generator 20, a signal detects and arithmetic unit 30, a power supply device 40 and an induction ball 50 constitute, wherein, this position signal generator 20 and induction ball 50 form an enclosure space, sliding path with restriction and guiding induction ball 50 is characterized in that:
This position signal generator 20 is made up of countless induction terminals 22 according to axial array, and each induction terminal 22 all is configured to have certain location signal value, induction ball 50 then contacts with the induction terminal 22 of this correspondence position according to its present position always, at any time send ad-hoc location signal value and give that signal detects and arithmetic unit 30, so when induction ball 50 because of stressed during according to axial slip, signal detects and arithmetic unit 30 just can detect the displacement union and go out the displacement acceleration according to diverse location signal value and the variation in the relative time.
Figure 2 shows that the structural representation of another preferred embodiment of the present invention, as seen from the figure, this induction ball 50 can be subjected to an elasticity to submit oneself to the traction of body 52, thereby can the reversion original position after external force is eliminated, and just becomes the starting point that signal makes zero and calculates.
Again as shown in Figure 3, Figure 4, add the synoptic diagram of housing for the induction ball of the 3rd preferred embodiment of the present invention.For being of value to the friction force that reduces induction ball 50 and respond to 22 of terminals, and avoid because of this friction force the operation values distortion that may cause, induction ball 50 in the present embodiment, added a framework 54, so that can freely roll in this framework 54 in induction ball 50 peripheries.
