Abstract

The invention provides an active starting signal device, belonging to a sub-system of a race timing system in the sports field. Because of introduction of a visual function, the invention can improve accuracy of 'reaction time' that is measured when athletes are starting to run. The invention adopts a main technical proposal that a controlling table arranged on a position of a start organizer is connected with a countdown device arranged near a starting line, and when the time goes to '0', a starting signal is given. When the athletes are in place, the athletes can prepare psychologically and physiologically when the time gradually goes to zero, thereby avoiding a tension state during passively waiting for the sound of a gun, and the 'reaction time' of the athletes is closer to a time which is sent by a starter. The active starting signal device has the following advantages of: 1. shortening the 'reaction time' and contributing to the improvement of scores; 2. making the starting times of athlete close and achieving a fairer race; 3. improving probability of success for once starting running, and is applicable to all the items which need to record the scores from starting, such as running, skating, bicycling, swimming and hurdling.

Description

Active starting signal apparatus

Technical field

The present invention be in a kind of track and field contest that is applied in the sports, make the runner understand device between the block clearance time of regulation on the horizon, the field that belongs to the signal system that clocks that when race use can make the sportsman initiatively grasp between the block clearance time of regulation and enters competitive state accurately and timely.Therefore, help the raising of games results, also can make contest more trend towards justice.

Background technology

In track and field sports, some are that signal makes the sportsman enter the project of competitive state with the sound, for example race, skating, bicycle, swimming, hurdle race etc., and its starting singal equipment is:

1, this is widely used when being common match for starting pistol.Its shortcoming is: because the aerial propagation of sound needs the time, so after shot rings, will postpone successively to hear gunshots far beyond sportsman far away apart from shot successively.Is example with 8 runways, temperature 20c Celsius ° the time: the sportsman of distal-most end will postpone to hear gunshots in about 0.03 second.This is deciding the project of achievement in 0.001 second for above-mentioned those, and the effect that so off equipment produces obviously is inequitable concerning the sportsman.

2, starting pistol and sound system thereof this be in blue-ribbon event, generally to use at present.This cover equipment is each sportsman loudspeaker to be set after one's death, has lead to link to each other with starting pistol.The sound of starting pistol is delivered to loudspeaker in the mode of the signal of telecommunication, and (speed of propagation of electrical signals is 300,000km/s, so the difference of runway near-end and far-end can be ignored), all loudspeaker all equate with the athletic distance relative with it, so each sportsman can hear gunshots at one time, reached fair purpose;

3, in addition, the electronics block that uses is to link to each other with the timer of starting pistol, terminal point at present, and its effect only is between the athletic block clearance time of monitoring and the interval difference of the time of starting pistol sound, if this difference has surpassed official hour, then be regarded as false start, belong to misconduct.

On sport history, created these projects certainly and begun, so far, all be to use the mode of above-mentioned " 1 " or " 2 ", " 3 " that contest is begun.But said method all has some unavoidable defective and deficiencies:

1, from macroscopical technological layer analysis

1) sportsman is from hearing that starting pistol sound to making the action that health begins to move, needs 0.1 second time at least, and this process is called " reaction time ".But everybody is difference to some extent in athletic reaction time.So, if calculate achievement,, and become the key factor that causes the final result difference so because the difference in athletic reaction time with the precision with 0.001 second of present use.Therefore, if " run duration " is constant, so, this final result can not accurately reflect athletic true achievement.(our said achievement at present, reflection be " global response time ", i.e. " reaction time " and " run duration " sum);

2) sportsman is in passive state, can only guess by virtue of experience when starting pistol can ring, owing to anxious to gain victoryly tend to false start, causes foul;

3) because the foul several times are promptly expelled, and sportsman false start or that some the is careful start of a race that may lag behind has promptly increased " reaction time ", this will seriously influence their true achievement;

4) the electronics block is helpless to the sportsman and initiatively grasps between block clearance time;

5) shot is every now and then to having made some noises on the sports ground.

2, from the concrete technical Analysis of timing system

1) at the terminal point of runway, modern science and technology---use the joint-cutting video camera can write down the correct time that the sportsman reaches home, its precision can reach 0.001 second;

2) in the starting point of runway, the sportsman just is regarded as false start so long as ring within back 0.1 second offly at shot, belongs to foul, and the start of a race then obeys the rule 0.1 second after.

3) we can see from above analysis: the accuracy of timekeeping of terminal point and starting point differs 100 times unexpectedly!

3, from humanistic and spiritual level analysis

1) since there being above-mentioned sports to begin, people have just ignored and have ignored athletic personality and dignity in other words, because sentence to capital punishment in that time of sportsman's start of a race with other people similarity is arranged to a certain extent: the two all is to wait for that in anxiety extremely shot sounds;

2) we often can see such situation: owing to occur false start need for the second time (even more times) restart off could success.This has not only delayed the time, has influenced sight, and " without letup, decline, three and exhaust " again, repeatedly off athletic dash tired out, and then can influence their achievement.

At human society in the process of rational and development of civilization, in the epoch of emphasizing ergonomics and hommization product, can rewrite in the historical record of athletic competition achievement at raising centisecond even signa, above-mentioned starting singal equipment obviously is out of season.

Search for the result in China's online input of invention " sports apparatus starting singal equipment ": this classification does not still have any record; In the same keyword of the online input of Chinese patent, result: blank.

Summary of the invention

Purpose of the present invention is to propose the starting signal apparatus that a kind of sportsman of making initiatively participates in.Use of the present invention can make the sportsman can trend towards more accurately in the stipulated time start of a race that the starter sends, thereby can shorten " reaction time ", measures the final result more accurately.Athletic dignity has obtained respect simultaneously, and can reduce the noise on the sports ground.

Here, the present invention presents a new concept simultaneously: sportsman's initiative participative management.Its meaning is: the sportsman just has been in since own athletic competition is always freed the state of management, monitored passivity, can consciously go to carry out, consciously go to observe, make on psychological and the physiology can both be before entering contest sufficient preparation arranged in an instant, make and obtain more excellent achievement and possessed condition.

The present invention is applicable to needs the accurately event of record achievement, for example race, skating, bicycle, swimming, hurdle race, or the like.

Technical essential of the present invention is:

1, near the visual line of sight the starting line of runway, when the sportsman is in place, is provided with a count-down device;

2, this count-down device can be the liquid crystal display display type, also can show with other mode of clocking;

3, based on people's physiological potency, the accuracy of this count-down device can be a centisecond;

4, near the position at common starter place, a console is arranged, the count-down digital display screen is arranged on the panel of console and function keys such as key, start key, numerical key, zero key, close key are set;

5, the count-down display screen of the starting line front end in console and each shunting that is positioned at runway links to each other, and makes time of being provided with on the control panel identical with display screen on the runway, and synchronous operation;

6, the starter starts the count-down table in due course after the time of setting, and the time makes zero trending towards, and the sportsman makes corresponding preparation, when making zero in the time, and sportsman's start of a race.

Compared with the prior art, (, can only compare) with the existing equipment that uses because of failing to retrieve and same device of the present invention, the present invention has following advantage:

1, the intention novelty is simple in structure, and is easy to implement;

2, with the concrete comparison (is example with the 100m dash) of prior art:

1) with the shot be the signal movement process:

1. the sportsman accepts stimulus information (hearing gunshots)---brain and central nervous system are sent instruction---, and muscle comes into play, and (this is the phase I, i.e. " between premotor reaction time ")---tissues such as muscle and ligament begin shrink---health begins to move that (this is second stage, i.e. " motor reaction time ") this sum of the two is called " reaction time ", is to belong to the preparatory stage." reaction time " generally is about 0.1 second.

2. health begins to move---and health moves finishes (line of reaching home), and this stage is called " run duration ", and this is only the real contest stage.

But we are alleged achievement at present, is meant above-mentioned " reaction time " and " run duration " sum, i.e. " response time ".

2) use the present invention to be the signal movement process:

1. in the time that is about to make zero in the time of count-down, the sportsman can finish the preparation rank in " reaction time ", that is to say and can omit " reaction time ";

2. finished the preparation of reaction owing to the preceding sportsman of " making zero " in the time, and the starting singal order is as the criterion for " zero " with the time and is to begin to clock with this, therefore, the sportsman has only " health begins to move---health moves to be finished " this process, promptly has only and record " run duration " only.

According to above analysis, theoretically, use the present invention that the achievement of 100m dash was improved about 0.1 second, this will rewrite the history of this project.

3, can tend to the more accurate same time start of a race, can be more accurate for the metering of achievement; Fair more for the sportsman;

4, the sportsman is become and is grasped initiatively that count-down makes zero and off by issue an order shot and the start of a race of passive hearing, can reduce the situation of flying;

5, disposable off success can make the sportsman " accomplish with one effort ", increases its dash, the new achievement of easier creation;

6, the present invention is the design that meets the hommization of ergonomics, body mechanics and Praxeology, can make athletic personality and dignity all obtain due respect;

7, no longer include shot, noise can be littler on the sports ground.
