Abstract
The invention provides a walking distance meter. The walking distance meter is installed on a shoe, and comprises a sound pick-up, a timer, a counter and an arithmetic device, wherein the timer is used for timing the time between two adjacent step sounds picked by the sound pick-up as footstep time; the counter is used for counting the total times of footstep sound picked by the sound pick-up; the operator is used for making differences of two adjacent periods of footstep time, obtaining the absolute value of the difference values, and then obtaining the average value of the absolute value of each difference value; the average value is multiplied by sound velocity, a correction factor and the total times of the footstep sound sequentially, thereby obtaining the walking distance. The walking distance meter can be used for automatically obtaining the step lengths, automatically measuring the walking distance, and improving the convenience of measurement.
Description
Technical field
The present invention relates to electronic device field, especially, relate to a kind of walking taximeter.
Background technology
In the ground survey process of zonule, sometimes need to measure by walking the distance in each place, at this moment need to use walking taximeter; Current walking taximeter has comprised passometer and arithmetical unit, and described passometer, by pressure transducer or acoustic pickup, records step quantity, and arithmetical unit is multiplied by step-length by step quantity, draws walking distance; But, because everyone step-length is different, even also can be different for the step-length under the various situations of same person, therefore, in use, also need manually to input step value, this just makes the use of this kind of walking taximeter seem comparatively inconvenient.
Summary of the invention
For the problems referred to above, the object of the present invention is to provide a kind of walking taximeter, this walking taximeter can automatic acquisition step-length, and automatically realizes the measurement of walking distance, has improved the convenience of surveying work.
The technical scheme that technical solution problem of the present invention adopts is: this walking taximeter is placed on footwear, comprise acoustic pickup, timer, counter, arithmetical unit, described timer carries out timing to the time between adjacent twice footsteps of described microphone pickup, while being denoted as step; Described counter is counted the footsteps total degree of described microphone pickup; Described arithmetical unit is poor during by each two sections of adjacent described step, and gets absolute difference, then gets the mean value of absolute difference described in each; This mean value is multiplied by the velocity of sound, then is multiplied by correction factor, then be multiplied by footsteps total degree, draw walking distance.
As preferably, described correction factor is cos10 °～cos15 °.
As preferably, during described step, keep 10～20 sections in mind.
Bright beneficial effect is: this walking taximeter in use, supposes that taximeter is installed on right crus of diaphragm, and first right crus of diaphragm is stepped out, and land, timer starts timing, until left foot lands rear left foot and lands acoustic propagation to right crus of diaphragm, like this, while keeping a described step in mind, in the time of might as well being called long step; Then, timer restarts timing immediately, until right crus of diaphragm lands, like this, while keeping again a described step in mind, in the time of might as well being called short step; As can be seen here, during long step, compare during with short step, many one is landed sound and from left foot, propagates into the time of right crus of diaphragm, and this time is multiplied by the velocity of sound, is in a step, left foot is to the distance of right crus of diaphragm, be multiplied by correction factor, equal step-length, by step-length, be multiplied by footsteps sum, be step number, equal walking distance.
Embodiment
Below the present invention is further described:
This walking taximeter is placed on footwear, comprise acoustic pickup, timer, counter, arithmetical unit, described timer carries out timing to the time between adjacent twice footsteps of described microphone pickup, described acoustic pickup inside comprises a Zener diode, voice signal for the breakdown reverse voltage lower than this Zener diode, all owing to cannot puncturing this diode, be left in the basket, for the voice signal higher than this Zener diode breakdown reverse voltage, again by exporting after a wave detector, described wave detector is ignored the voice signal different from footsteps characteristic frequency again as noise.
Time between described adjacent twice footsteps is in the time of might as well being denoted as (being called) step; Described counter is counted the footsteps total degree of described microphone pickup; Described arithmetical unit is poor during by each two sections of adjacent described step, and gets absolute difference, then gets the mean value of absolute difference described in each; This mean value is multiplied by the velocity of sound, then is multiplied by correction factor, then be multiplied by footsteps total degree, draw walking distance.
Above-mentioned walking taximeter, described correction factor is cos10 °～cos15 °, generally, the forward foot in a step is in oblique the place ahead of the rear foot, and the arch of the foot line of the forward foot in a step, the rear foot and working direction are generally 10 °～15 °, therefore, according to footsteps propagation distance, the distance that draws the arch of the foot line of the forward foot in a step, the rear foot, is multiplied by described correction factor, just obtains actual distance of advancing towards dead ahead.During described step, keep 10～20 sections in mind.
Above-mentioned walking taximeter in use, supposes that taximeter is installed on right crus of diaphragm, and first right crus of diaphragm is stepped out, and lands, and timer starts timing, until left foot lands rear left foot and lands acoustic propagation to right crus of diaphragm, like this, while keeping a described step in mind, in the time of might as well being called long step; Then, timer restarts timing immediately, until right crus of diaphragm lands, like this, while keeping again a described step in mind, in the time of might as well being called short step; As can be seen here, during long step, compare during with short step, many one is landed sound and from left foot, propagates into the time of right crus of diaphragm, and this time is multiplied by the velocity of sound, is in a step, left foot is to the distance of right crus of diaphragm, be multiplied by correction factor, equal step-length, by step-length, be multiplied by footsteps sum, be step number, equal walking distance.
Claims (3)
1. a walking taximeter, this walking taximeter is placed on footwear, it is characterized in that: this taximeter comprises acoustic pickup, timer, counter, arithmetical unit, described timer carries out timing to the time between adjacent twice footsteps of described microphone pickup, while being denoted as step; Described counter is counted the footsteps total degree of described microphone pickup; Described arithmetical unit is poor during by each two sections of adjacent described step, and gets absolute difference, then gets the mean value of absolute difference described in each; This mean value is multiplied by the velocity of sound, then is multiplied by correction factor, then be multiplied by footsteps total degree, draw walking distance.
