Embodiment
Below provide specific embodiment of the utility model, need to prove that the utility model is not limited to following specific embodiment, all equivalents of doing on present techniques scheme basis all fall into protection domain of the present utility model.
Defer to technique scheme, as depicted in figs. 1 and 2, a kind of mangneto fluctuating acceleration sensor, comprise cylindrical metal shell 4, metal shell 4 inwalls are provided with layer of metal plate 8, the positioning disk 5 of pair of parallel in two discs 41 of metal shell 4 is installed between two discs 41 of metal shell 4, the smooth guide pole 3 that can move in the center pit 51 of positioning disk 5 is installed on the center pit 51 of positioning disk 5, guide pole 3 two ends link to each other with two discs 41 of metal shell 4 by spring 1 respectively, and being equipped with on the guide pole 3 can be along the metal oscillator 2 of guide pole 3 slips; Be equipped with one deck pottery 7 in the middle of the sheet metal 8, pottery 7 is provided with the field coil 6 of a pair of symmetry; Sheet metal 8 links to each other with the input end of single-chip microcomputer 10 by signal processor 9, and the output terminal of single-chip microcomputer 10 links to each other with controllable electric power 11, and controllable electric power 11 links to each other with field coil 6.
Single-chip microcomputer 10 adopts the STC189C51 single-chip microcomputer; Signal processor 9 adopts ZMD31050 sensor signal process chip.
Controllable electric power 11 adopts the sony CR2032 of Sony power supply, and its voltage is easily controlled, and anti-tampering property is strong, is fit to be applied to sensor.
When dynamic excitation, acceleration transducer of the present utility model is measured its vibration source intensity, and when institute's vibration measuring was moving stronger, its measured signal was handled by signal processor 9, and physical signalling is converted to digital signal, passes to single-chip microcomputer 10 again.
When vibration is strong, metal oscillator 2 changes fast with sheet metal 8 relative displacements, the storage of the condenser charge that metal oscillator 2 and sheet metal 8 are formed, discharge and accelerate, produce electric signal with this and give signal processor 9, signal processor 9 is accepted this electric signal and is handled, physical signalling is converted to digital signal, pass to single-chip microcomputer 10 then, single-chip microcomputer 10 is according to the gained digital signal, control controllable electric power 11 strengthens the electric current input, electric current produces bigger magnetic field by field coil 6 thus, metal oscillator 2 is in relative sheet metal 8 vibration processes, because the magnetic field that exists field coil 6 to produce, produce the magnetic induction resistance that hinders metal oscillator 2, reduce the relative motion of metal oscillator 2 and sheet metal 8 with this, according to the measurement range of the definite acceleration transducer of the present utility model of adding electric current size, realize the adaptively changing range simultaneously with this.In like manner, when extraneous excitation density was more weak, single-chip microcomputer 10 control controllable electric powers 11 electric currents reduced, even are zero, and the rigidity of like this applied spring 1 realizes measuring, and range is reduced, and improves precision.
