Description
Technical field
The present invention relates to a kind of arm pressure signal acquisition methods, are primarily adapted for use in the research field of assistance mechanical arm.
Background technology
The present invention relates to a kind of arm pressure signal acquisition methods.In the research process of power assistant arm, it is necessary first to opponent
Arm signal is acquired analysis.Currently, most of both at home and abroad analyzed using arm surface electromyography signal, but due to surface
Electromyography signal is weak physiological signal, and very similar to random signal from form during human body is done exercises, and signal-to-noise ratio is low,
Current signal recognition method can't highly reliably realize accurately identifying for multiple Modal actions, and there is the knowledges of certain mistake
Not rate, this method are not used widely also.In order to overcome this difficulty, improve measurement result, because of a kind of hand of the invention
Arm pressure signal acquisition method, this method make arm rigidization avoid influence of the physiological characteristic for signal acquisition of arm,
And the pressure signal harvester in this method carries scale, and it can be with the pressure signal on wheel measuring different location, in turn
Achieve the purpose that measurement.
Invention content
It is an object of the present invention in view of the above-mentioned problems, a kind of arm pressure signal acquisition method be proposed, to solve in power assistant arm
Research process in for the destabilizing factor that occurs when arm signal acquisition, and the pressure signal harvester in this method
Multigroup measured value can be obtained by rotating different angles.
The technical solution adopted by the present invention to solve the technical problems is：Steel pipe uses cylindrical shape, for preferably mould
The shape of quasi- arm, is equipped with air bag between inner ring and steel pipe, airbag aeration enables the gap between inner ring and steel pipe to fill up, makes
Each symmetrical place's uniform force of inner ring is obtained, furthermore uses thermoplasticity inner ring, enables rigidization at its stress, avoids the soft of air bag
Influence of the property for measurement, clamps sensor with the similar iron plate of diameter and sensor diameter, it is made to be pressurized
Power is entirely delivered to sensor, avoids the insufficient factor of force acting on transducer, indicates on air bag and respectively scale in inner ring,
The output valve of different location can be obtained by rotating inner ring, the scale value on air bag and inner ring is completely superposed so that rotation
Turn more purpose, it is also very clear to rotate how many degree.
Advantageous effect：
1. the present invention is mainly used for acquiring the pressure signal of arm, and makes arm rigidization, arm physiological characteristic pair is avoided
In the influence of measured value.
2. pressure signal harvester according to the present invention is simple in structure, long lifespan, it is easy for assemble or unload, convenient for taking
Material and cheap.
3. the present invention is easy to operate, acquisition signal is more true.
It is follow-up real 4. pressure signal harvester according to the present invention can obtain multigroup measured value by rotation
It tests and a variety of data references is provided.
Fully meet the purpose of the present invention.
Description of the drawings
The following further describes the present invention with reference to the drawings.
Fig. 1 is the overall structure form of arm pressure signal pickup assembly.
Fig. 2 is the internal structure chart of arm pressure signal pickup assembly.
Main appended drawing reference explanation：
In Fig. 1：1, rope；2, steel pipe；3, air bag；4, inner ring；5, outer shroud；6, iron plate；7, sensor.
Specific implementation mode
Below in conjunction with the accompanying drawings, the specific implementation mode of the present invention is described in detail, it is to be understood that the guarantor of the present invention
Shield range is not restricted by specific implementation.
Referring to attached drawing, steel pipe is used（2）The arm for simulating human body, is tied with air bag with a scale on steel pipe（3）Device, in gas
Capsule outer surface is put on graduated thermoplasticity annulus（Inner ring）, in inner ring（4）Eight small iron plates in outside face（6）It clamps respectively
Four FSR sensors（7）, outer shroud（5）It is cut into mutual disjunct four part, is separately fixed at the small iron plate being distributed in 90 degree
It is external.
Rope when measurement（1）It binds counterweight or other calibration value weights is naturally put on outer shroud, change when loading only
Weight need to be changed, rotation inner ring can measure the pressure signal in different angle, set that there are four identical biographies on the device
Sensor, and sensor is uniformly distributed, so need to only be rotated by 90 °, sensor experiences pressure, is arrived by Du Pont's line outflow
In the signal conditioning circuit set.
