As a result, the liquid resistant ring 146 prevents a damage of the circuit board 143 caused by water which enters the accommodating space 1413 through the first through hole 1414. Similarly, the other liquid resistant ring 146 is coupled with the second fastening end 1422 in the same way, and the other liquid resistant ring 146 is located in the second through hole 1415. As a result, the liquid resistant ring 146 prevents the damage of the circuit board 143 caused by water which enters the accommodating space 1413 through the second through hole 1415.

The liquid resistant loop 147 connects the two liquid resistant rings 146. The liquid resistant loop 147 is dispose at the junction between the top case 1411 and the bottom case 1412 so as to seal a gap between the top case 1411 and the bottom case 1412. The liquid resistant loop 147 is made of, for example, silicone or plastic. Therefore, the liquid resistant loop 147 prevents the damage of the circuit board 143 caused by water which enters the accommodating space 1413 through the gap between the top case 1411 and the bottom case 1412.

The processing module 230 is configured to select one conversion parameter from the conversion parameter table in the storage module 220 according to the user information, and the processing module 230 is also configured to generate a tension information according to the tension from the sensor 140. Therefore, the exercise information is obtained by the computation of the processing module 230 according to the tension information and the conversion parameter. The tension information includes the tension and the timing corresponding to the tension. Specifically, the tension information includes the tension and the timing when the tension is measured. The exercise information includes an instantaneous swimming speed information, an average swimming speed, a swimming distance, or a calorie expenditure. The instantaneous swimming speed information includes the instantaneous swimming speed and the timing corresponding to the instantaneous swimming speed. Specifically, the instantaneous swimming speed information includes the instantaneous swimming speed and the timing when the tension for the conversion of the instantaneous swimming speed is measured.

The output module 240 is configured to output the exercise information obtained by the computation of the processing module 230.

In the first embodiment of the present disclosure, the processing module 230 selects a proper conversion parameter from the conversion parameter table according to the user's height, weight, and swimming stroke. This conversion parameter table is built according to the experiment data. The experiment data is collected from the users, who use a specific swimming stroke but with different height and weight, when they swimming normally in the conventional swimming pool and from the users equipped with the training device 100 when they swimming in the water tank. The conversion parameters, which are for the conversion between the user's instantaneous forward force and the instantaneous swimming speed, are conducted according to water resists of the users' heights, weights, and swimming strokes. In the first embodiment of the present disclosure, when the swimming stroke is the breaststroke, the conversion parameter table is shown in the following table 1. Since the user is restrained by the training device 100, the instantaneous forward force generated by the user, who is swimming, is equal to the tension in the connecting component 110, the tension measured by the sensor 140 is the instantaneous forward force generated by the user, who is swimming. As a result, the user's instantaneous swimming speed is computable by the processing module 230 according to a formula (I), the tension measured by the sensor 140, and the conversion parameter selected according to the user information.

V=ef; Formula (I)

wherein, V is the instantaneous swimming speed, e is the conversion parameter, and f is the tension.

Further according to the tension measured by the sensor 140, the timing corresponding to the tension, the user information, and the conversion parameter, the average swimming speed, the swimming distance, or the calorie expenditure are computable by the processing module 230.

In the first embodiment of the present disclosure, the training device 100 helps the user to swim in the swimming pool or the water tank in a restrained swimmable distance. The processing device 200 computes the user's exercise information of the swimming process according to the tension information provided by the training device, and the processing device 200 also helps the user to execute the swim training program according to the exercise information. The processing device 200 is, for example, a smart phone or a tablet PC. The input module 210 and the output module 240 are, for example, a touch panel of the smart phone or the tablet PC, or a wireless communication module of the smart phone or the tablet PC. The storage module 220 is, for example, a memory of the smart phone or the tablet PC. The processing module 230 is, for example, a processor of the smart phone or the tablet PC. In the first embodiment of the present disclosure, the processing device 200 is the smart phone or the tablet PC, and the wireless communication module 250 is the Bluetooth communication module, but the disclosure is not limited thereto. In other embodiments of the present disclosure, the processing device is a desktop computer, and the input module is a mouse, keyboard, or the wireless communication module, and the storage module is a hard disk, and the processing module is a central processing unit (CPU), and the output module is an external screen.

In the first embodiment of the present disclosure, when the bar 140 of the sensor 140 is pulled, the Bluetooth communication module in the training device 100 and the Bluetooth communication module in the processing device 200 are paired to be communicatively connected to each other. As a result, when the user is using the swim training system, the tension measured by the sensor 140 is instantly transmitted to the processing device 200.

The following illustrates steps of a swim data computation method for the swim training system in the first embodiment of the present disclosure. Please refer to FIG. 6. FIG. 6 is a flow chart of a swim data computing method for the swim training system according to the first embodiment of the present disclosure.

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

In detail, the user's height, weight, and swimming stroke are inputted into the processing module or the storage module by the user with the input module.

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

In detail, the proper conversion parameter is selected from the conversion parameter table by the processing module according to the user's height, weight, and swimming stroke which are inputted into the processing module or the storage module. For example, when the height, the weight, and the swimming stroke inputted by the user are respectively 175 centimeters, 70 kilograms, and breaststroke, the processing module selects the conversion parameter table of the breaststroke, which is the above table 1, and then selects e=0.0130284 as the conversion parameter from table 1.

Next, measure the tension by the sensor (S103).

In detail, the sensor measures the tension in the connecting component when the user is swimming. The tension measured by the sensor is outputted by the wireless communication module. A time interval of the tension measurement by the sensor is, for example, 0.1 second, but the disclosure is not limited thereto. In other embodiments of the present disclosure, the time interval of the tension measurement by the sensor is 0.01 second to 1 second.

Next, acquire the tension information by the processing module according to the tension obtained from the sensor (S104).

In detail, the tension sent by the wireless communication module is received by the processing module. After the processing module receiving the tension, a timing is given to the tension as a tag by the processing module to obtain the tension information.

Next, obtain the exercise information by the processing module according to the tension information and the conversion parameter (S105).

In detail, the instantaneous swimming speed V is obtained by the computation of the processing module according to the formula (I) V=ef, the conversion parameter e, and the tension f in the tension information. Next, the average swimming speed or the swimming distance is further obtained by the computation of the processing module according to two timings and two instantaneous swimming speeds respectively corresponding to the two timings in two tension information. Next, the calorie expenditure is further obtained by the computation of the processing module according to the user information, the two timings and the two instantaneous swimming speeds respectively corresponding to the two timings in the two tension information.

In the step S105, the processing module converts the tension, which is a physical quantity of force, to the instantaneous swimming speed, which is a physical quantity of velocity, according to the conversion parameter selected from the conversion parameter table. As a result, the swim training system in the first embodiment of the present disclosure not only help user to swim in the swimming pool or the water tank with the restrained swimmable distance, but also converts the tension in the connecting component to the instantaneous swimming speed according to the conversion parameter in the conversion parameter table with the cooperation between the training device and the processing device.

In the swim data computation method for the swim training system in the first embodiment of the present disclosure, the step S102 to the step S104 are executed in sequence, but the present disclosure is not limited thereto. In other embodiments of the present disclosure, the step S102 and the step S103 in the swim data computation method have no particular order to be executed, or the step S102 and the step S104 in the swim data computation method have no particular order to be executed.

In the swim data computation method for the swim training system in the first embodiment of the present disclosure, the conversion parameter is selected according to the user's height, weight, and swimming stroke, but the present disclosure is not limited thereto. In other embodiments of the present disclosure, the conversion parameter is calibrated according to the user's gender, arm length, leg length, or waistline so as to further improve the accuracy of the instantaneous swimming speed obtained by the computation.

The following illustrates steps of a swim training method for the swim training system in the first embodiment of the present disclosure. Please refer to FIG. 7 to FIG. 11. FIG. 7 is a flow chart of a swim training method for the swim training system according to the first embodiment of the present disclosure. FIG. 8 to FIG. 11 are schematic views of a display screen of an output module of the swim training system according to the first embodiment of the present disclosure.

First, build a comparison exercise information of a comparison swimming process in the storage module (S201).

In detail, input and store the comparison exercise information of the comparison swimming process into the storage module by the input module, or record the comparison exercise information of the comparison swimming process by the swim training system. The comparison exercise information includes a Nth comparison instantaneous swimming speed to a (N+1)th comparison instantaneous swimming speed and a Nth timing to a (N+1)th timing which respectively correspond to the Nth comparison instantaneous swimming speed to the (N+1)th comparison instantaneous swimming speed, or a Nth comparison tension information to a (N+1)th comparison tension information and the Nth timing to the (N+1)th timing which respectively correspond to the Nth comparison tension information to the (N+1)th comparison tension information; wherein, the N is a positive integer greater than zero. The comparison exercise information is able to further include a Nth comparison swimming distance which is corresponding to the Nth timing, or a Nth comparison average swimming speed which is corresponding to the Nth timing. When the comparison exercise information is the exercise information recorded by the swim training system from the same user, there is no need to enter the user information again. When the comparison exercise information is the exercise information recorded by the swim training system from a previous user, the user needs to input a previous user information of the previous user so that the processing device is able to select a proper conversion parameter for executing the conversion between the comparison tension information and the comparison instantaneous swimming speed.

Next, select the conversion parameter from the conversion parameter table by the processing module according to the user information (S202).

Next, measure the training tension by the sensor (S203).

In detail, a Nth training tension to a (N+1)th training tension are respectively measured at the Nth timing to the (N+1)th timing by the sensor. The Nth training tension corresponds to the Nth timing, and the (N+1)th training tension corresponds to the (N+1)th timing. As a result, timing intervals of the training tensions measured by the sensor are the same as the timing intervals of the comparison instantaneous swimming speeds or the timing intervals of the comparison tension information so as to provide a basis for comparison on an equal timing interval.

Next, acquire the training tension information by the processing module according to the training tension, which is obtained from the sensor (S204).

In detail, the Nth training tension to the (N+1)th training tension, which are transmitted by the wireless communication module, are received by the processing module. After the processing module receives the Nth training tension to the (N+1)th training tension, the Nth training tension to the (N+1)th training tension are tagged by the timing to acquire the Nth training tension information to the (N+1)th training tension information by the processing module.

Next, obtain the training exercise information by the processing module according to the conversion parameter and the training tension information (S205).

In detail, the training instantaneous swimming speed V is obtained by the computation executed by the processing module according to the formula (I), the conversion parameter e, and the training tension f in the training tension information. Next, the average training swimming speed or the training swimming distance is able to be obtained by the further computation executed by the processing module according to the Nth training instantaneous swimming speed and the (N+1)th training instantaneous swimming speed which are respectively corresponding to the Nth timing and the (N+1)th timing. Next, the calorie expenditure is able to be obtained by the further computation executed by the processing module according to the user information, the Nth training instantaneous swimming speed and the (N+1)th training instantaneous swimming speed which are respectively corresponding to the Nth timing and the (N+1)th timing.

Next, compare the comparison exercise information and the training exercise information corresponding to each other by the processing module to obtain a comparison result (S206).

In detail, the Nth training instantaneous swimming speed and the Nth comparison instantaneous swimming speed, which are corresponding to the Nth timing, are compared by the processing module, or the Nth training average swimming speed and the Nth comparison average swimming speed, which are corresponding to the Nth timing, are compared by the processing module, or the Nth training swimming distance and the Nth comparison swimming distance, which are corresponding to the Nth timing, are compared by the processing module.

Next, output the comparison result by the output module after the training exercise information corresponding to the timing is obtained by the processing module but before the training exercise information corresponding to the next timing is obtained by the processing module (S207).

In detail, when the comparison result is that the Nth comparison instantaneous swimming speed is greater than the Nth training instantaneous swimming speed, the processing module comments the output module to output a first notification. When the comparison result is that the Nth comparison instantaneous swimming speed is smaller than the Nth training instantaneous swimming speed, the processing module comments the output module to output a second notification. When the comparison result is that the Nth comparison average swimming speed is greater than the Nth training average swimming speed, the processing module comments the output module to output the first notification, when the comparison result is that the Nth comparison average swimming speed is smaller than the Nth training average swimming speed, the processing module comments the output module to output the second notification. When the comparison result is that the Nth comparison swimming distance is greater than the Nth training swimming distance, the processing module comments the output module to output the first notification. When the comparison result is that the Nth comparison swimming distance is smaller than the Nth training swimming distance, the processing module comments the output module to output the second notification.

Before the processing module obtains the comparison result of the (N+1)th timing, the processing module comments the output module to output the comparison result of the Nth timing so that the output module is able to instantly provide the comparison result to the user. Therefore, the user is able to realize the user's performance is better or worse than the performance in the comparison swimming process, but the disclosure is not limited thereto. In other embodiments of the present disclosure, the processing module is also available to comment the output module to output all the comparison results of all the timings at once after obtaining all the comparison results of all the timings.

In the swim training method for the swim training system in the first embodiment of the present disclosure, the step S202 to the step S204 are executed in sequence, but the present disclosure is not limited thereto. In other embodiments of the present disclosure, the step S202 and the step S203 in the swim training method have no particular order to be executed, or the step S202 and the step S204 in the swim training method have no particular order to be executed.

As shown in FIG. 8 to FIG. 11, the comparison exercise information, the training exercise information, and the comparison result are visualized to be presented by the output module, but the disclosure is not limited thereto. The comparison exercise information, the training exercise information, and the comparison result are presented in sound by the output module to notify the user. For example, the output module presents the exercise information in digital form on the display, and the output module uses the line graph to show the instantaneous swimming speeds at different timings and the bar graph to show the accumulation of the calorie expenditure. Moreover, as shown in FIG. 11, the output module presents the bar graph of the comparison swimming distance Dr and the bar graph of the training swimming distance Dt on the display at every corresponding timings. The distance difference d between the comparison swimming distance Dr and the training swimming distance Dt is marked on the display so that the comparison result between the comparison swimming distance and the training swimming distance is able to be realized easily in a short time by the user.

In the swim training method for the swim training system in the first embodiment of the present disclosure, after the processing module compares the training exercise information and the comparison exercise information, the processing module comments the display module to provide the first notification or the second notification to the user according to the comparison result. Therefore, during the swim training process, the user is notified by the display module about that the user's swimming performance is better or worse than the swimming performance of the comparison swimming process. As a result, the swim training method for the swim training system in the first embodiment of the present disclosure helps the user to execute the swim training program for improving the training result.

The following illustrates a swim training system 2 in the second embodiment of the present disclosure. Please refer to FIG. 12. FIG. 12 is a schematic view of a swim training system according to a second embodiment of the present disclosure. The swim training system 2 in the second embodiment of the present disclosure is similar to the swim training system 1 in the first embodiment of the present disclosure. Only the differences between the swim training system 2 and the swim training system 1 are explained herein, and the same structures thereof are not repeated herein.

The swim training system 2 in the second embodiment of the present disclosure includes a training device 100′, a processing device 200′, a buoyancy auxiliary device 300, and a photography device 400. The buoyancy auxiliary device 300 is disposed at the wearing component 120 so as to provide an auxiliary buoyancy to the user. The buoyancy auxiliary device 300 is, for example, floats or airbags installed at the wearing component 120. In the second embodiment of the present disclosure, the buoyancy auxiliary device is located at the user's ventral side, but the disclosure is not limited thereto. In other embodiments of the present disclosure, the buoyancy auxiliary device is located at the user's backside or waist side.

When the user is swimming in the swimming pool without the training device 100 in the swim training system 1, a relative movement between the user and the water flow generates a buoyancy for the user. However, when the user is swimming in the swimming pool with the training device 100 in the swim training system 1, there is no relative movement between the user and the water flow so that no buoyancy is generated for the user. As a result, the user swimming with the swim training system 1 spends an extra strength to maintain the swimming stroke since the lower body tends to sink.

The buoyancy auxiliary device 300 in the swim training system 2 provides the auxiliary buoyancy to compensate the buoyancy generated by the relative movement between the user and the water flow. As a result, the user's lower body has no tendency to sink, and the user has no need to spend the extra strength to maintain the swimming stroke.

Comparing with the wearing component 120 without the buoyancy auxiliary device 300, after the wearing component 120 is equipped with the buoyancy auxiliary device 300, the user's swimming stroke and force using method are changed. Therefore, the storage module in the processing device 200′ further stores a buoyancy parameter table for calibrating the conversion parameter. A proper conversion parameter is selected from the conversion parameter table as an original conversion parameter by the processing module according to the user's height, weight, and swimming stroke. A buoyancy parameter is also selected from the buoyancy parameter table by the processing module according to the magnitude of the auxiliary buoyancy. The original conversion parameter is calibrated with the buoyancy parameter by the processing module to obtain a conversion parameter. Next, the instantaneous swimming speed is obtained by the processing module according to the conversion parameter and the tension measured by the sensor 140′. An average swimming speed, a swimming distance, or a calorie expenditure is further obtained by the processing module according to the conversion parameter, the tension measured by the sensor 140′, a timing corresponding to the tension, and the user information.

The buoyancy parameter table in the swim training system 2 of the second embodiment of the present disclosure is shown in the following table 2.

After the float number is selected from table 2 by the processing module according to the user's weight in the user information, the original conversion parameter is calibrated with a formula (II) to obtain the conversion parameter.

e=e

wherein, e is the conversion parameter, e₀is the original conversion parameter, and f_nis the float number.

The photography device 400 is disposed around the swimming pool or the water tank and communicatively connected to the processing module.

The user image photoed or shot by the photography device 400 is able to be directly displayed on the output module.

In the swim training system 2 of the second embodiment, the processing device 200′ is, for example, a desktop computer, and the input module is, for example, a mouse, a keyboard, or a wireless communication module. The storage module is, for example, a hard disk. The processing module is, for example, a central processing unit (CPU). The output module is, for example, an external screen. The photography device 400 is, for example, an external camera. However, the present disclosure is not limited thereto. In other embodiments of the present disclosure, the processing device is a smart phone or a tablet PC, and the photography device is the camera of the smart phone or the tablet PC.

The following illustrates steps of a swim data computation method for the swim training system in the second embodiment of the present disclosure. Please refer to FIG. 13. FIG. 13 is a flow chart of a swim data computing method for the swim training system according to the second embodiment of the present disclosure. The step S301, and 304 to S307 in the swim data computation method for the swim training system 2 in the second embodiment is similar to the step S101, and 103 to S105 in the swim data computation method for the swim training system 1 in the first embodiment.

In detail, the proper original conversion parameter is selected from the conversion parameter table by the processing module according to the user's height, weight, and swimming stroke, which are inputted into the processing module or the storage module. For example, when the height, the weight, and the swimming stroke inputted by the user are respectively 175 centimeters, 70 kilograms, and breaststroke, the processing module selects the conversion parameter table of the breaststroke, which is the above table 1, and then selects e=0.0130284 as the original conversion parameter from table 1.

Next, select a buoyancy parameter from the buoyancy parameter table stored in the storage module by the processing module according to the auxiliary buoyancy provided to the user by the buoyancy auxiliary device (S303).

In detail, the float number of the buoyancy auxiliary device is determined by the user according to the user's weight. Next, the proper buoyancy parameter is selected from the buoyancy parameter table by the processing module according to the float number, which is proportional to the magnitude of the buoyancy. The float number, as a part of the user information, is inputted in to the processing module or the storage module by the user, but the disclosure is not limited thereto. In other embodiments of the present disclosure, the proper float number is selected from the table 2 by the processing module according to the user's weight in the user information.

Next, calibrate the original conversion parameter with the buoyancy parameter by the processing module to obtain the conversion parameter (S304).

In detail, the original conversion parameter is calibrated with the buoyancy parameter by the processing module to obtain the conversion parameter. For example, when the user's weight is 70 kilograms, the buoyancy auxiliary device has 4 floats. The original conversion parameter e₀is subtracted 0.0000562*4 to obtain the conversion parameter e=0.0128036 according to formula (II) e=e₀−0.0000562*f_nby the processing module.

As a result, the instantaneous swimming speed, which is converted from the tension by the swim data computation method for the swim training system in the second embodiment, is more close to the actual instantaneous swimming speed of the user swimming in the conventional swimming pool without the training device.
