Description
Technical field
Invention relates to a kind of digital shoes based on pressure sensor.
Background technology
In track and field event, China has certain basis in events such as woman's middle-distance race and footrace, man's 110 meter high hurdle, is repeatedly obtaining prominent success in the Olympic Games and the world's track and field competitive bidding match.But track and field is traditional project of American-European countries, even if on the surging small project of China, we also are far from being for how many advantages, can only say to have advanced international standard at most, other let alone numerous track and field events.
The scientific training tool of track and field is more single at present, except monitoring, the special ability of the physiological and biochemical index of routine take exercise with improve, the main kinematics information that obtains training process by high speed video recording analysis system, with this evaluation analysis Motion Technology, this analytical work amount is huge, needs off-line to implement, it is convenient in real time to accomplish, and changed by scene and the constraint of calibration system, the way that can only adopt single-point to disperse is obtained local process information.For obtaining in real time of the step appearance gait information in athlete's motion process, do not see special effective method as yet, and athletic step appearance gait information has great importance to estimating athletic technical merit and improvement, therefore presses for step appearance gait technology for information acquisition in the exploitation track and field event.Based on the digital track shoes of flexible array pressure sensor, can detect, obtain the sportsman in real time and carry out the track and field event step appearance gait information in when training, obtain letters such as step number, the time of sportsman in motion process, the situation of soaring from the heart.
The core technology of system is to use the digital track shoes of flexible array power/touch sensor, detects the athletic situation that lands, and obtains the step appearance information in sportsman's motion process.The detection plantar pressure distribution measuring technology that is found in early to pressure distribution.It is documented, just finished the research of plantar pressure distribution measuring as far back as Beely in 1882.Measuring technique goes so far as in the more advanced footwear from the simplest direct reprography and fills up measuring technique.U.S. Tekscan company develop a kind of economy, fast, accurately, efficiently, pressure distribution measuring system intuitively, be exactly the sensor construction of Tekscan pressure distribution measuring system.The unique distinction of Tekscan pressure distribution measuring system is its patented technology fexible film grid sensor one by one.
The Tekscan pressure sensor of standard is made up of two very thin polyester films, and wherein the inner surface of a slice film is laid the tape conductor of several rows, and the inner surface of another sheet film is laid the tape conductor of some row.The width of conductor itself and line space can design according to different measurement needs.The conductor appearance scribbles special pressure-sensitive semiconductor material coating.When two films were integrated, a large amount of horizontal conductors and the crosspoint of longitudinal conductor had just formed the pressure sensitive lattice array.When external force affacted on the induction point, semi-conductive resistance can the proportional variation with the variation of external force, reflected the force value of induction point thus.Be pressure when being zero, the resistance maximum, pressure is big more, and resistance is more little, thereby can reflect the pressure distribution situation between two contact-making surfaces.
More and more be familiar with and paid attention to because pressure distribution is measured in the using value in fields such as industry, body science, behavior science by the mankind, bow I has played paying close attention to of developed country, except that above-mentioned Tekscan, also have famous brand names such as U.S. SPI, Belgian Rrscan to occupy most market shares in the whole world, these foreign brand name prices are very expensive, with pad detection system in the footwear is example, and most external product prices all reach tens thousand of dollars, and domestic industry is difficult to bear.
Adidas Internat Marketing B. V has submitted patent of invention " footwear and case " on March 21st, 2006 to Patent Office of the People's Republic of China, and its application number is: 2006100652566, publication number is CN1839724A.This invention relates to a kind of sport footwear for weight training or body-building application, the shoe sole component of this sport footwear has recess and is used for dismountable mode and holds electronic installation, the case that holds electronic pedometer, accelerometer or velocity sensor, wherein case has and the corresponding shape of sole center dant shape.This invention can not only be contained in sensor groups in the sole removably and sole is made of one, and can be whole electronic installations, as pedometer, accelerometer or velocity sensor, MP3 player or other any suitable electronic installation is assembled in the sole and sole is made of one.Utilize cable or radio transmitting device, can couple together additional user interface and above-mentioned electronic installation, even, also can import and read the data that record like this in when operation.
According to State Patent Office's retrieval center new patent searching, do not seen and be directed to the athletic training use, can obtain the trainer shoe of step appearance information, seen be all simple provide weight training or body-building are used.What the training in the present domestic sports match pressed for is: by measuring the step appearance gait of sportsman in motion process, obtain technical parameters such as athletic step frequency, action sequence, thereby analyze.
Summary of the invention
The present invention seeks to provides a kind of digital shoes based on pressure sensor at the defective that prior art exists.
The present invention adopts following technical scheme for achieving the above object:
The present invention is based on the digital shoes of pressure sensor, the numerous pressure sensors that it is characterized in that comprising signaling conversion circuit, microprocessor, radio-frequency transmissions chip, radiofrequency receiving chip, radio frequency reader, data collecting card, terminal handler and be arranged at sole surface, wherein the output of pressure sensor is connected in series signaling conversion circuit, microprocessor, radio-frequency transmissions chip successively, the output of radiofrequency receiving chip is connected in series radio frequency reader, data collecting card, terminal handler successively, radio-frequency transmissions chip and radiofrequency receiving chip wireless connections.
The present invention the invention has the beneficial effects as follows:
One, the digital track shoes based on flexible array pressure sensor of the present invention comprise left and right running shoes
With the electronic device that places in it, and invest information gathering transmission part and power supply on the human body, wherein: electronic device is the shoe-pad of the pressure sensor that is equipped with in the running shoes and the interface that is electrically connected with it, the front end of shoe-pad, half sole both sides and rear end are equipped with the pressure sensor more than, pressure sensor is electrically connected with interface, is used for converting the pressure from the different parts place of sole to the signal of telecommunication;
