Brief description of the drawings
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, to the accompanying drawing of required use in embodiment or description of the Prior Art be briefly described below, apparently, accompanying drawing in the following describes is only embodiment more of the present utility model, for those of ordinary skill in the art, do not paying under the prerequisite of creative work, can also obtain according to these accompanying drawings other accompanying drawing.
Fig. 1 is the structural representation of a kind of fiber body load measurement device of the present utility model;
Fig. 2 is the structural representation of the Fibre Optical Sensor demodulating system of a kind of fiber body load measurement device of the present utility model.
Embodiment
Below in conjunction with drawings and Examples, the utility model is described in further detail.Following examples are used for illustrating the utility model, but can not be used for limiting scope of the present utility model.
Fig. 1 is the structural representation of a kind of fiber body load measurement device of the present invention; Fig. 2 is the structural representation of the Fibre Optical Sensor demodulating system of a kind of fiber body load measurement device of the present invention; Device of the present invention, comprises trigger board 1, Fibre Optical Sensor 2, optical fiber 3, solar electric power supply system 4, Fibre Optical Sensor demodulating system 5.Described Fibre Optical Sensor 2 is fiber-optic grating sensor, and Fibre Optical Sensor 2 is fixed in trigger board 1 by the mode of welding, and Fibre Optical Sensor 2 is connected with Fibre Optical Sensor demodulating system 5 by optical fiber 3, and solar electric power supply system 4 is connected with Fibre Optical Sensor demodulating system 5; Described Fibre Optical Sensor demodulating system 5 is made up of light source module 6, spectral analysis module 7, built-in PC processor 8, built-in PC processor 8 is connected with light source module 6 controls the light signal of launching to Fibre Optical Sensor 2, and built-in PC processor 8 is connected to realize the light signal that Fibre Optical Sensor 2 is reflected back and receives and analyze with spectral analysis module 7.
Described trigger board 1 is the carrying position while surveying body weight; Described Fibre Optical Sensor 2 bears the variation of weight for being used for experiencing trigger board; Described Fibre Optical Sensor demodulating system 5 is for realizing the wavelength detection of fiber grating; Described solar electric power supply system 4, for utilizing solar cell to collect sun power, and is electric energy by light energy conversion, offers Fibre Optical Sensor demodulating system power supply.
The course of work of measuring body weight is as follows:
Utilize solar cell to provide power supply to Fibre Optical Sensor demodulating system, Fibre Optical Sensor is fixed in trigger board, in the time that people stand in trigger board, trigger board shape changes, cause that the fiber grating reflected light signal wavelength in Fibre Optical Sensor changes, the reflected light after modulation is turned back to demodulating system by Fibre Optical Sensor, extracts change information on the spot and analyze from light signal, is finally converted into the output of body weight numerical value.Wherein built-in PC processor 8 body running principles are as follows: the spectrum of described Fibre Optical Sensor 2 reflected light signals carries strain value information, this light signal is changed into electric signal by described spectral analysis module 7, electric signal enters in described built-in PC processor 8, the strain value that the elastic modulus of trigger board 1 that built-in PC processor 8 bases pre-enter and the spectrum of Fibre Optical Sensor 2 reflected light signals carry just can calculate trigger board 1 pressure, i.e. alleged body weight.
A kind of fiber body load measurement device provided by the invention, this measurement mechanism volume is small and exquisite, and inner structure is simple, and degree of accuracy is high, is easy to carry.
Above embodiment is only for the utility model is described, but not to restriction of the present utility model.Although the utility model is had been described in detail with reference to embodiment, those of ordinary skill in the art is to be understood that, the technical solution of the utility model is carried out to various combinations, revises or is equal to replacement, do not depart from the spirit and scope of technical solutions of the utility model, all should be encompassed in the middle of claim scope of the present utility model.
