Next, the steps of the swimming data calculation method using the swimming training system of the first embodiment of the present invention will be described, please refer to FIG. 6. 6 is a flowchart of a swimming data calculation method of a swimming training system according to a first embodiment of the present invention.

First, input user information from the input module (S101).

In detail, the user inputs the user's height, weight and swimming posture from the input module to the processing module or the storage module.

Next, the processing module selects conversion parameters from the conversion parameter table according to the user information (S102).

In detail, the processing module selects appropriate conversion parameters from the conversion parameter table according to the user's height, weight, and swimming posture input by the user into the processing module or the storage module. For example, when the user enters a height of 175 cm, a weight of 70 kg, and a swimming style of frog, the processing module selects the frog conversion parameter table in Table 1 and selects e = 0.0130284 as the conversion parameter from Table 1. .

Next, the detector detects the tension value (S103).

In detail, the detector measures the tension value that the connecting member bears when the user swims. The tension value measured by the detector is sent out through the wireless communication module. The time interval for the detector to detect the tension value is, for example, 0.1 second, but not limited to this. In other embodiments of the present invention, the time interval for the detector to detect the tension value is, for example, 0.01 second to 1 second.

Next, the processing module obtains the tension value from the detector to obtain tension information (S104).

In detail, the processing module receives the tension value sent by the wireless communication module. After receiving each tension value, the processing module gives each tension value a time node label to obtain tension information.

Next, the processing module calculates motion information according to the conversion parameters and tension information (S105).

In detail, the processing module calculates an instant swimming speed V according to the formula (I) V = ef by calculating the conversion constant e and the tension value f in the tension information. Formula (I) is the relationship between the tension value and the instantaneous time integral to obtain the total user work output by the user in the instantaneous time, and the relationship between the total user work, the user's weight and the instantaneous swimming speed V. Since the user's swimming posture, height and weight will affect the total work output by the user in an instant, and also affect the conversion between total work, user weight and instantaneous swimming speed V, the conversion constant is selected e time must be based on the user's height, weight and swimming style used.

Furthermore, in the swimming data calculation method using the swimming training system of the first embodiment and other embodiments of the present invention, the corrected swimming time can be used as the corrected swimming time according to the actual swimming time of the user in the general swimming pool and the corresponding swimming distance Swimming distance with correction. Next, use the swimming training system to swim at the same time as the corrected swimming time, and calculate the user's total work and the user's swimming distance. Next, the processing module corrects the original conversion parameters selected from the conversion parameter table based on the difference between the user's swimming distance and the corrected swimming distance to obtain the conversion parameters. For example, in the calibration mode, the user first enters the swimming time required to complete a 25-meter swim in a general swimming pool for 30 seconds, and then uses the swimming training system to swim for 30 seconds. The processing module of the swimming training system corrects the original conversion parameters according to the difference between the user's swimming distance calculated by the processing module and the actual swimming distance of 25 meters in the general swimming pool. In this way, the converted parameters obtained after the correction can make the total work measured by the user when using the swimming training system closer to the total work done by the user during actual swimming, thereby further increasing the calculated instantaneous swimming speed Accuracy.

Then, the processing module may further calculate the average training swimming speed or the training swimming distance according to the Nth training instantaneous swimming speed corresponding to the Nth time node and the N + 1th training instantaneous swimming speed corresponding to the N + 1 time node. Then, the processing module may further calculate calorie consumption according to the user information, the Nth training instant swimming speed corresponding to the Nth time node and the N + 1 training instant swimming speed corresponding to the N + 1 time node.

Next, the processing module compares the corresponding control sports information with the training sports information to obtain a comparison result (S206).

The processing module selects the appropriate conversion parameter from the conversion parameter table as the original conversion parameter according to the user's height, weight and swimming posture used. The processing module also selects a buoyancy parameter from the buoyancy parameter table according to the magnitude of the auxiliary buoyancy, and corrects the original conversion parameter with the buoyancy parameter to obtain the conversion parameter. Then, the processing module can calculate the instantaneous swimming speed of the user based on the tension value measured by the detector 140 'and the conversion parameters. Further based on the tension value measured by the detector 140 ', the time node corresponding to the tension value, user information and conversion parameters, the processing module can calculate the average swimming speed, swimming distance or calorie consumption.
