Problems solved by technology

[0003] In 2018, there were 1,581 domestic marathon events, covering 31 provinces, municipalities, and autonomous regions across the country. In marathon competitions, the number and curvature of the track in different cities, as well as the ups and downs of the track are different, making different The degree of difficulty of the track is different. Now the difficulty of the track is mainly estimated subjectively, and accurate measurement cannot be achieved. Therefore, we propose a calculation method for on-site measurement and calculation of the difficulty level of the track during a marathon

Embodiment 1

[0021] Measure the starting and ending distance of the entire track through GPS satellites, record the changes in the width of the entire track, record the number of curves through the data fed back from the GPS satellite map, and record the turning angle of each group of curves at the same time, and at the same time according to different curvatures Divide it into different stages, record the altitude of the entire track, and use the altimeter to mark the areas where the altitude fluctuations of different stages change on the corresponding positions on the track, and mark the altitude difference on the track According to the change area of ​​the track, the track is segmented and marked into groups according to the corners, and the length of each group of segments is recorded at the same time. The top 20 rankings, the bottom 20 rankings, and the middle 30 rankings of each group are used. The famous time-consuming data is used to calculate the speed of each group of curves accor...

Embodiment 2

[0023] Measure the starting and ending distances of the entire track through GPS satellites, record the changes in the width of the entire track, record the number of curves through the data fed back from the GPS satellite map, and record the turning angle of each group of curves at the same time, and compare the altitude of different stages The area where the ups and downs change is marked on the corresponding position on the track, and the altitude difference is marked on the changing area of ​​the track. At the same time, it is divided into different stages according to different curvatures, and the time spent by the participants passing through different stages is recorded. , and then plot the time consumption, altitude, wind speed and temperature of the day in a set of tables for observation analysis.

Embodiment 3

[0025] Sensors are installed on each group of restrooms in the stage to record the entry of participants. According to the data recorded by the sensors, the frequency of use of the restrooms can be observed, and it is concluded that 3KM is the most reasonable distance between the restrooms.

Abstract

The invention discloses a calculation method for on-site measurement and calculation of the degree of difficulty of the track in a marathon competition. S1. Drawing the data of the entire track: measuring the overall length of the track, measuring the starting and ending distances of the entire track through GPS satellites, and recording Changes in the width of the entire track; measure the number of curves and curvature of the track, record the number of curves through the data fed back from the GPS satellite map, and record the turning angle of each set of curves; measure the altitude of the track, The altitude of the track is recorded in the record, and the area where the altitude changes in different stages is marked on the corresponding position on the track. The present invention calculates the equivalent long-distance running distance and the speed of the participants by measuring the length of the overall track, the number of curves and angles of the track, and through multiple sets of data, and finally calculates the equivalent long-distance running distance and the speed of the participants The overall time is obtained by the ratio, and the overall time is compared with the time of the actual participants, and the difficulty of the track can be understood according to the ratio.

Description

technical field [0001] The invention relates to the technical field of marathon competitions, and more specifically relates to a calculation method for on-site measurement and calculation of the degree of difficulty of a track during a marathon competition. Background technique [0002] Marathon (Marathon) long-distance running is a very popular long-distance running competition in the world. The whole distance is 26 miles and 385 yards, which is equivalent to 42.195 kilometers. There are three types of marathon: full marathon, half marathon and quarter marathon. The full marathon is the most popular, and the general mention of the marathon refers to the full marathon. The marathon is a high-intensity long-distance competitive sport. Long-distance running such as the marathon is conducive to improving the cardiovascular health of the human body and reducing the body's various blood pressure. Diseases and other organ diseases such as the prostate can also accelerate the body...
