Detailed Description
The invention will be further elucidated and described with reference to the embodiments and drawings of the specification:
a method of evaluating the performance of a sailboat competition player, comprising the steps of:
s1, acquiring the original data of the sailing of the competition players from the sailing competition management system;
s2, calculating one or more of sailing score, starting score and chord change score of the competition player according to the raw data of the competition player.
The viewer can check one or more of the navigation score, the starting score and the chord change score calculated by the method according to the own requirements, the navigation score, the starting score and the chord change score are all distributed between 0 and 100, the closer the score is to 100, the better the playing is, and the common viewer can accurately analyze the playing condition of one competition player in three aspects of navigation, starting and chord change in a certain round of competition by comparing the navigation score, the starting score and the chord change score of different competition players: which aspect performs well and which aspect does not; the process of calculating and analyzing the complex navigation data by looking at the motion trail is avoided, and the analysis efficiency of the viewer is improved.
The original data comprises navigation data, and the navigation data comprises a flight segment number, the time consumption of the corresponding flight segment, the average speed of the corresponding flight segment, the mileage of the corresponding flight segment and the average effective speed of the corresponding flight segment.
When a viewer needs to check the navigation score of a competition player, after the navigation data is obtained, the navigation score of the competition player is calculated according to the following four calculation formulas:
calculating a first formula: s%. alpha + v%. beta + l%. 100. gamma.;
s% is the proportion of the average speed in the full round competition of the competition players among all the competition players, v% is the proportion of the average effective speed in the full round competition of the competition players among all the competition players, l% is the proportion of the total driving range in the full round competition of the competition players among all the competition players, and alpha, beta and gamma are weight ratios.
When α, β, and γ are 0.2, 0.4, and 0.4, respectively, the calculation formula is: s% x100 x 0.2+ v% x100 x 0.4+ l% x100 x 0.4, the calculated voyage score now is closer to the actual voyage level of the contestant.
Calculating a second formula: s% = (s-s ')/(s "-s'), s = (t1 ·s1+. + tn sn)/(t 1+. + tn);
s is the average speed of the contestants throughout a round, s' is the minimum of the average speeds of all contestants in a round, and s "is the maximum of the average speeds of all contestants in a round; t 1-tn are the time of different flight segments, and s 1-sn are the average speed of different flight segments.
Calculating a formula III: v% = (v-v ')/(v "-v'), v = (t1 v1+. + tn v)/(t 1+. + tn);
v is the average effective speed of the contestant over the course of a round of the contest; v 'is the minimum value of the average effective navigational speeds of all the contestants in a round of competition, and v' is the maximum value of the average effective navigational speeds of all the contestants in a round of competition; t 1-tn are the time of use of different flight segments, and v 1-vn are the average effective flight speeds of different flight segments.
Calculating a fourth formula: l% =1- (l-l ')/(l "-l'); l = l1+. + ln;
l is the total driving mileage of the competition players in the whole competition round, l 'is the minimum value of the total driving mileage of all the competition players in the competition round, and l' is the maximum value of the total driving mileage of all the competition players in the competition round; l 1-ln are the driving mileage of different voyage sections respectively. Although the straight-line distances between each leg are the same, the routes actually traveled by different players are not straight lines, so that the actual total traveled mileage of different players is different, and since the total traveled mileage is smaller and the time consumption is smaller at a certain speed, the total traveled mileage in the entire round of competition by the players is better as the percentage (l%) of the total traveled mileage among all the players is smaller.
When the calculation is carried out according to the method, the sailing score of the competition player is calculated according to the following two steps:
first, the average speed (s%) of a full round of contest for a contestant over all contestants is calculated as follows:
s=（t1*s1+...+tn*sn）/(t1+...+tn)；s%=（s-s＇）/（s＂-s＇）;
for example, when the time spent by a player in competition # 1 in 4 legs is 400 seconds, 300 seconds, 400 seconds, 500 seconds, respectively, and the average speeds of the 4 legs are 8 m/second, 9 m/second, and 10 m/second, respectively, the average speed of the player in competition # 1 in the whole round of competition is:
s = (400 × 8+300 × 8+400 × 9+500 × 10)/(400 +300+400+ 500) =8.8 m/s.
When the minimum average speed in the round of the competition is 8m/s and the maximum average speed is 12m/s, the ratio of the average speed in the whole round of the competition for the competition player # 1 to all competition players is:
s%=（8.8-8）/（12-8）=20%。
the average effective speed (v%) of the entire round of competition among the competition players is calculated as follows:
v=(t1*v1+...+tn*vn)/(t1+...+tn)；v%=（v-v＇）/（v＂-v＇）；
for example, when contestant # 1 spends 400 seconds, 300 seconds, 400 seconds, 500 seconds, respectively, at 4 legs, and the average effective rates of flight for the 4 legs are 7.8 meters/second, 7.6 meters/second, 8.6 meters/second, and 9.6 meters/second, respectively, the average effective rates of flight for contestant # 1 over the entire round of the contest are:
v = (400 × 7.8+300 × 7.6+400 × 8.6+500 × 9.6)/(400 +300+400+ 500) =8.5 m/s.
When the minimum average effective speed in the round of competition is 7.2 m/s and the maximum average effective speed is 11.4 m/s, the ratio of the average effective speed in the whole round of competition of the competition player No. 1 to all competition players is:
v%=（8.5-7.2）/（11.4-7.2）=31%。
calculating the total driving range (l%) of the competition players in the whole round of competition, wherein the calculation formula is as follows:
l=l1 +...+ln；l%=1-（l-l＇）/（l＂-l＇）；
for example, when the mileage of contestant 1 in 4 legs is 3200 meters, 2400 meters, 3600 meters and 5000 meters, respectively, the total mileage of contestant 1 is:
l =3200+2400+3600+5000=14200 meters.
When the minimum total mileage of the round of the competition is 13800 m and the maximum total mileage of the round of the competition is 14800 m, the total mileage of the entire round of the competition player for the competition player No. 1 is in the following proportion among all the competition players:
v%=1-（14200-13800）/（14800-13800）=60%。
and secondly, calculating the sailing score by the occupation ratio of the average speed in the whole round of competition of the competition players in all the competition players, the occupation ratio of the average effective navigational speed in the whole round of competition of the competition players in all the competition players and the occupation ratio of the total driving mileage in the whole round of competition of the competition players in all the competition players, wherein the calculation formula is as follows:
s%*100*0.2+v%*100*0.4+l%*100*0.4；
for example, the navigation score for contestant # 1 can be derived as follows:
20%*100*0.2+31%*100*0.4+60%*100*0.4=40.4。
since the raw data also includes the departure data, the departure data includes the departure favorable side of the contestant, the departure favorable distance of the contestant, the departure delay of the contestant, and the actual speed of the contestant when taking off the departure route.
When the viewer needs to check the starting-up scores of the competition players, after the starting-up data is obtained, the sailing scores of the competition players are calculated according to the following five calculation formulas:
calculating a first formula: k%. 100. delta. + t%. 100. epsilon. + m%. 100. lambda.;
k% is the proportion of the favorable starting distance of the contestants among all contestants, t% is the proportion of the starting delay of the contestants among all contestants, m% is the proportion of the actual speed of the contestants when the starting route is rushed out in all contestants, and delta, epsilon and lambda are weight ratios.
When δ, ε, and λ are 0.4, 0.3, and 0.3, respectively, the calculation is:
k%. 100.4 + t%. 100.3 + m%. 100.0.3; the launch score calculated at this time is closer to the actual launch level of the contestant.
Calculating a second formula: k% = (k-k ')/(k "-k');
k is the advantageous distance to take off, k' is the minimum value of the advantageous distances to take off for all contestants in a round, and k "is the maximum value of the advantageous distances to take off for all contestants in a round.
Calculating a formula III: t% =1- (t-t ')/(t "-t');
t is the starting delay time, t 'is the minimum value of the starting delay time of all competition players in the round of competition, and t' is the maximum value of the starting delay time of all competition players in the round of competition; since the smaller the starting delay time, the less the race players take, the smaller the occupation ratio of the starting delay time of the race players among all race players is, the better.
Calculating a fourth formula: m% = (m-m ')/(m "-m');
m is the actual speed when the starting course is flushed, m 'is the minimum value of the actual speeds of all contestants in a round of contest when the starting course is flushed, and m' is the maximum value of the actual speeds of all contestants in a round of contest when the starting course is flushed.
Calculating a formula V: when the departure favorable side is the left side of the air route: k = i/j × d, when the departure vantage side is the right side of the route: k = (1-i/j) × d;
i is the distance on the right side of the departure route at the departure time, j is the length of the departure route, and d is the maximum dominant distance of the favorable side.
When the calculation is carried out according to the method, the sailing scores of competition players are calculated according to the following three steps:
first, calculating the starting favorable distance (k) of the competition player according to the following formula:
when the departure favorable side is the left side of the air route: k = i/j × d;
when the departure favorable side is the right side of the air route: k = (1-i/j) × d;
for example, when the departure favorable side of the contestant No. 1 is the right side of the flight path, and the distance on the right side of the flight path when the contestant No. 1 departs from the flight path is 20 meters, the length of the departure line is 50 meters, and the maximum dominant distance of the favorable side is 10 meters, the departure favorable distance of the contestant No. 1 is as follows:
k=（1-20/50）*10=6。
secondly, calculating the proportion (k%) of the starting favorable distance of the competition player in all competition players, wherein the calculation formula is as follows:
k%=（k-k＇）/(k＂-k＇);
for example, since the above favorable starting distance for contestant No. 1 is 6 meters, when the minimum value of the favorable starting distances among all contestants is 4 meters and the maximum value of the favorable starting distances is 8 meters, the ratio of the favorable starting distances of contestant No. 1 among all contestants is as follows:
k%=（6-4）/(8-4)=50%。
calculating the proportion (t%) of the starting delay of the competition players in all competition players as follows:
t%=1-(t-t＇）/（t＂-t＇）;
for example, when the starting delay time of contestant 1 is 0.5 seconds, the minimum value of the starting delay times of all contestants is 0.2 seconds, and the maximum value of the starting delay times is 0.7 seconds, the ratio of the starting delay time of contestant 1 to the starting delay time of all contestants is as follows:
t%=1-(0.5-0.2）/（0.7-0.2）=40%。
calculating the proportion (m%) of the actual speed of the contestant when the contestant rushes out of the starting route in all contestants, wherein the calculation formula is as follows:
m%=(m-m＇）/（m＂-m＇）;
for example, when the actual speed of the contestant No. 1 when leaving the starting course is 3 m/sec, the minimum value of the actual speeds of all contestants when leaving the starting course is 2.5 m/sec, and the maximum value of the actual speeds when leaving the starting course is 3.3 m/sec, the ratio of the actual speed of the contestant No. 1 when leaving the starting course among all contestants is as follows:
m%=(3-2.5）/（3.3-2.5）=63%。
thirdly, calculating the starting-up score of the competition player according to the occupation ratio of the starting-up favorable distance of the competition player in all the competition players, the occupation ratio of the starting-up delay of the competition player in all the competition players and the occupation ratio of the actual speed of the competition player on the starting-up route in all the competition players, wherein the calculation formula is as follows: k%. 100. delta. + t%. 100. epsilon. + m%. 100. lambda.;
for example, the starting score for contestant # 1 can be derived as follows:
50%*100*0.4+40%*100*0.3+63%*100*0.3=50.9
since the original data also includes the transposition data, the transposition data includes the total number of transposition of the contestant and the operation loss of the contestant.
When the viewer needs to check the chord change score of the contestant, after the chord change data are obtained, the chord change score of the contestant is calculated according to the following three calculation formulas:
calculating a first formula: x%. mu + f%. 100. sigma.;
x% is the proportion of the total number of the strands in the whole round of competition of the competition players in all the competition players, f% is the proportion of the operation loss in the whole round of competition of the competition players in all the competition players, and mu and sigma are weight ratios.
When μ and σ are 0.4 and 0.6, respectively, the calculation formula is: x%. 100.4 + f%. 100.6;
the chord change score calculated at this time is closer to the actual chord change level of the contestant.
Calculating a second formula: x% =1- (x-x ')/(x "-x');
x is the total number of the game players in the whole round of the game, x 'is the minimum value of the total number of the game players in the round of the game, and x' is the maximum value of the total number of the game players in the round of the game; since the fewer the number of times the player changes strings, the less time is wasted, the fewer the total number of string changes in the entire round of the competition by the player is, the better.
Calculating a formula III: f% =1- (f-f ')/(f "-f');
f is the total operation loss of the competition players in the whole competition round, f 'is the minimum value of the total operation loss of all the competition players in the competition round, and f' is the maximum value of the total operation loss of all the competition players in the competition round; since the less the operation loss of the contestant, the less the time is used, the smaller the occupation ratio of the operation loss in the entire round of the contestant among all the contestants is, the better.
When the calculation is carried out according to the method, the chord change score of the competition player is calculated according to the following two steps:
first, the proportion (x%) of the total number of the string changes of the competition players in the whole round of competition among all the competition players is calculated, and the calculation formula is as follows:
x%=1-（x-x＇）/（x＂-x＇）；
for example, when the total number of strands in the whole round of competition by the contestant No. 1 is 10, the minimum value of the total number of strands in all contestants in the round of competition is 6, and the maximum value of the total number of strands in all contestants in the round of competition is 15, the total number of strands in the whole round of competition by the contestant No. 1 is as follows:
x%=1-（10-6）/（15-6）=55%；
calculating the operation loss of the competition players in the whole round of competition, wherein the operation loss accounts for f% of all the competition players, and the calculation formula is as follows:
f%=1-（f-f＇）/（f＂-f＇）；
for example, when the total operation loss of the player for competition No. 1 in a full round of the competition is 40 meters, the minimum value of the total operation loss of all the players in a round of the competition is 20 meters, and the maximum value of the total operation loss of all the players in a round of the competition is 50 meters, the operation loss of the player for competition No. 1 in the full round of the competition is as follows:
f%=1-（40-20）/（50-20）=33%。
secondly, calculating the chord change scores of the competition players according to the occupation ratio of the total chord change number of the competition players in the whole round competition among all the competition players and the occupation ratio of the operation loss of the competition players in the whole round competition among all the competition players, wherein the calculation formula is as follows:
x%*100*μ+f%*100*σ；
for example, the chord change score for contestant # 1 can be derived as follows:
55%*100*0.4+33%*100*0.6=41.8。
when the viewer needs to know the comprehensive play level of a competition player in the multi-round competition, the starting score, the sailing score and the chord change score of the competition player in the multi-round competition can be respectively averaged.
