Description
The invention relates to the field of sports training automation, in particular to a digital running shoe based on a flexible array pressure sensor.
Background
In the track and field project, China has a certain foundation on items such as long-distance running and heel-and-toe walking in women, 110 m high-hurdle in men and the like, and obtains excellent results on multiple Olympic games and world track and field competitive bidding competitions. However, track and field are traditional projects in European and American countries, and even in the strong small projects of our country, we can not talk about the advantages, at most, the track and field have the advanced level in the world, and more particularly, other track and field projects are provided.
At present, the scientific training means of track and field is single, besides the monitoring of the conventional physiological and biochemical indexes and the special ability training and improvement, the kinematics information in the training process is mainly obtained by a high-speed image analysis system, so that the motion technology is evaluated and analyzed, the analysis workload is huge, the off-line implementation is required, the real-time convenience cannot be realized, and the local process information can only be obtained by adopting a single-point discrete method under the constraint of scene change and a calibration system.
No particularly effective method is found for the real-time acquisition of the walking gait information of the athletics athletes in the process of movement, and the walking gait information of the athletes has important significance for evaluating the technical level of the athletes and improving, so that the technology for acquiring the walking gait information in the athletics project is urgently needed to be developed. The digital running shoe based on the flexible array pressure sensor can detect and acquire the gait and gait information of the athlete during track and field project training in real time, and acquire the information of the number of steps, time, flight condition and the like of the athlete in the process of sports.
The core technology of the system is a digital running shoe using a flexible array force/touch sensor to detect the landing condition of the athlete and obtain the tread information of the athlete during the movement. Detection of pressure distribution is earlier seen in plantar pressure distribution measurement techniques. Beely completed plantar pressure distribution measurements as early as 1882, documented. The measurement technology has been developed from the simplest direct copying technology to the more advanced insole measurement technology. The Tekscan company in the united states develops an economical, rapid, accurate, efficient and intuitive pressure distribution measurement system, namely a sensor structure of the Tekscan pressure distribution measurement system. The Tekscan pressure distribution measurement system is unique in its patented technology-flexible thin film grid sensor.
A standard Tekscan pressure sensor consists of two very thin sheets of mylar, one of which has rows of strip conductors laid on the inside surface and the other having columns of strip conductors laid on the inside surface. The width of the conductors themselves and the line spacing can be designed for different measurement needs. The conductor is coated with a special coating of a pressure-sensitive semiconducting material. When the two films are combined into a whole, a large number of crossing points of the transverse conductors and the longitudinal conductors form a pressure sensing point array. When an external force acts on the sensing point, the resistance value of the semiconductor changes proportionally with the change of the external force, so that the pressure value of the sensing point is reflected. When the pressure is zero, the resistance is the largest, and the larger the pressure is, the smaller the resistance is, so that the pressure distribution condition between the two contact surfaces can be reflected.
As the application value of pressure distribution measurement in the fields of industry, human body science, behavior science and the like is more and more known and valued by human beings, the important attention of developed countries is attracted, besides the Tekscan, the famous brands such as the American SPI, the Belgium Rrscan and the like occupy most market shares all over the world, the foreign brands are very expensive, the price of most foreign products reaches tens of thousands of dollars by taking an inner shoe pad detection system as an example, and the domestic industry is hard to bear.
The invention discloses a shoe and a cover shell, which is submitted to the Chinese patent office on 21.3.2006 by Adida International Business administration and application numbers of: 200610065256.6, publication No. CN 1839724A. The invention relates to a sports shoe for weight training or fitness applications, the sole part of which has a recess for detachably accommodating an electronic device, a housing accommodating an electronic pedometer, accelerometer or speed sensor, wherein the housing has a shape corresponding to the shape of the recess in the sole. The invention not only allows the sensor to be removably incorporated into the sole of a shoe, but also allows all the electronic devices, such as pedometers, accelerometers or speed sensors, MP3 players or any other suitable electronic device to be incorporated into the sole of a shoe. An additional user interface can be connected to the electronic device by means of a cable or wireless transmission means, so that the measured data can be entered and read even during operation.
According to the research of the research center of the national patent office, the training shoes which are used for track and field training and can obtain the walking posture information are not found, and the training shoes are used for purely providing load-bearing training or body-building application. At present, the training in the domestic sports competition needs urgently: the technical parameters of the athlete such as step frequency, action time sequence and the like are obtained by measuring the step gait of the athlete in the process of movement, so as to carry out analysis.
