Abstract
The race walking monitoring equipment includes at least one first sensor for monitoring the athlete's sole state, at least one second sensor for monitoring the athlete's heel state, and one signal treating device for treating the signals from the sensors. The sensors are set inside show sole and this has no influence on the race walking athlete. The present invention can solve the problem of monitoring the technological state of athlete's soles in low cost.
Description
Technical field
The present invention relates to a kind of monitoring equipment, particularly a kind of equipment that is used to monitor walker's state of the art.
Background technology
Footrace is a surging project in China field circles, and China walker has won first Olympic gold medal of track and field event in the 25th Olympic Games.Yet heel-and-toe walking contest is the very project of " extremely " of a technical stipulation, and the example that the sportsman fails because of technical offence occurs repeatedly, and many elites also usually can be charged a foul and striking out.This has sportsman's technology problem not stable in performance, and judge's problem is also arranged, and this is because footrace is a unique match that comes penalty to break the rules by naked eyes, from all difficult yardstick of holding technical offence of sportsman, coach and judge.
Footrace definition according to International Track and Field Association's " international track and field rules of contest ": " footrace is that keep in touch on sportsman and ground, and the process that strides forward does not continuously have (human eye) as seen to soar.Foreleg should stretch (being that knee joint must not be crooked) from moment to the vertical position that contacts to earth." rule pointed out that as seen two key technologies of footrace both " can not have and soar " and " knee joint must not crooked ".
Research report " Liping Wang, Hongyu LIU are participated in the 27th Olympic Games pre-games technical Analysis " according to the General Administration of Sport the Administrative Center of Track and Field, they have taken two player motion with high-speed camera, the key technology of " soaring " and " straight leg " to them is resolved, reach a conclusion and be: (1) is because the visual persistence effect of human eye, soaring below 42 milliseconds is that naked eyes can't be seen, therefore according to rule as long as duration of passage is exactly not visible less than 42 milliseconds, the time limit below 42 milliseconds that therefore requires athletic flight part to be controlled to be invisible to the naked eye; (2) point of observation for " straight leg " judge is the sole elevation angle, and the elevation angle thinks then that greater than 10 ° knee joint stretches when contacting to earth, and the foot heel to contact to earth at first be the foreleg important symbol that moment stretches of contacting to earth.
Summary of the invention
The purpose of this invention is to provide a kind of novel race walking monitoring equipment.
The objective of the invention is to be achieved through the following technical solutions:
A kind of race walking monitoring equipment comprises: at least one be used to monitor sportsman's sole state first sensor, at least one is used to monitor second sensor and a signal processor that is used to handle the sensor signal of sportsman's heel state.
Wherein, it also comprises at least one shoe-pad, and this first sensor is located at the sole position of this shoe-pad, and this second sensor is located at the heel position of this shoe-pad.
Wherein, this signal processor comprises a single-chip microcomputer, and is connected a memory on this single-chip microcomputer, this machine alarm, a transmitter and a LCDs.
Positive progressive effect of the present invention is: the monitoring problem that has solved two big technical offences of walking events; Sensor is located in the shoe-pad, and feel is almost consistent with common shoe-pad with weight, can not exert an influence to the sportsman.Make simple, with low cost.Can and train the motion state that any time is provided for the sportsman, help them that athletic motion conditions is analyzed, improve the athletic level of training.
Description of drawings
Fig. 1 is the schematic diagram of one embodiment of the invention.
The specific embodiment
Provide preferred embodiment of the present invention below in conjunction with accompanying drawing, to describe technical scheme of the present invention in detail.
As shown in the figure, a kind of race walking monitoring equipment comprises:
Two shoe-pads of Cheng Shuan, for left foot shoe-pad 1, right insole 1 ';
Be located at respectively the first sensor 2,2 at left and right sides pin shoe-pad 1,1 ' sole position ', they are pressure sensor;
Be located at respectively second sensor 3,3 at left and right sides pin shoe-pad 1,1 ' heel position ', it is pressure sensor;
An AVR single-chip microcomputer 4 (MAGE8), its PORTC.0～PORTC.3 is the sensor input port, reception is from the signal of above-mentioned each sensor, and each sensor is output high level (logical one) during pressurized (less touch with the ground) not, output low level (logical zero) during pressurized (pin is stepped on ground);
A transmitter 5 that is connected on this single-chip microcomputer 4, PORTD.2 to PORTD.4 transmits the foul signal to this transmitter 5 respectively, the radio transmission module has four data inputs, can be used for transmitting data signal, in the present embodiment, PORTD.2 is " foul of soaring " signal, PORTD.3 is " the crooked foul of left front leg " signal, PORTD.4 is " the crooked foul of RAT " signal, and " 0 " representative does not have foul, " 1 " representative foul;
This machine alarm 6 that links to each other with the PORTD.5 of this single-chip microcomputer 4 is represented " foul of soaring " and " the crooked foul of foreleg " respectively with two kinds of differentiable sound;
A memory 7 that links to each other with this single-chip microcomputer 4 is used to store relevant data, can adopt EEROM;
One is connected LCD 8 (LCD) with the PORTB mouth of this single-chip microcomputer 4, content that can display-memory 7.
Coach or judge can use far-end radio receiver 9 to receive the signal of transmitter 5 emissions, utilize another single-chip microcomputer to form alarm 10, convert the foul signal to different voice signal.
