Description

Fitness equipment with heavy piece wisdom plug and its recording system

The invention relates to an accessory for a fitness equipment, in particular to a wisdom plug of a fitness equipment and a recording system for recording motion data by using a smart plug.

Since the birth of heart rate recording devices, pedometers, speed recorders and other sports history related recording devices, professional athletes and amateur sports enthusiasts have gained a deeper understanding of their physical functions and sports performance, and helped them improve themselves. Athletic performance. However, one of the most vulnerable items in sports training programs - weight training, because of its easy-to-record fitness equipment design is not easy, the traditional gym weight training equipment users can only rely on their own feelings or unreliable memory, to decide Each training weight is so likely to cause one of the following conditions: 1. When the training weight is insufficient, it causes invalid training; 2. When the training weight is too heavy, it causes sports injury. Most importantly, there is no easy way to record the user's current training weight, and the system can achieve this goal.

For the correct weight training method, the number of complete strokes and the number of groups of 2 to 3 cycles should be performed 10 to 12 times in the correct posture. At present, the most common way to record is to use the pen and paper record table, and there are also smart phone application software for manual input. However, it is very troublesome to carry the pen and paper records in the gym. It is both complicated and inconvenient to manually input the data of the weight, the number of times, the number of groups and the data of the previous training using the application software, except for the coach of the team. Individuals can consistently manually record their weight, number of times, and number of groups.

The more troublesome part is that when the trainer can exercise the fitness equipment to perform a certain operation smoothly, the weight should be increased by 5%. Because of the inconvenience of the pen and paper record, most amateurs only do it once a week. Or less than one weight training, can not accurately remember the data of the previous training, can only rely on the impression guess, in addition to the results of the inability to propose weight training compared with peers, can not be mutually motivated to increase the motivation of the movement, but also It is impossible to increase the intensity of weight training according to the training history in a timely manner, and perform weight training efficiently. Among the users who do weight training from time to time, there is no historical record, they can only randomly select the weight according to the current situation, and it is impossible to track the progress or regression of their muscle strength.

Because the existing fitness equipment lacks the design of recording training data, and it is very troublesome to input the training data in the smart mobile application software afterwards, it is not easy for the fitness person to obtain the training data, and the training intensity adjustment and the result sharing cannot be performed according to the historical data of the training. . To this end, the present invention provides a fitness equipment weighting wisdom plug and a fitness equipment weighting bolt recording system, with the system for each weight training record, the weight and number of each weight training can be tracked to understand the training process To solve the above problem of weight training.

When the weight detected by the latch is zero, it is a static state, and the processing value is increased until the value of the upper edge is decreased to the number of times the weight is trained by the lower edge value; and the process is repeated between the two stationary states. The value is increased to the number of repetitions of the group weight training after the upper edge value is reduced to the number of repetitions by the lower edge value; a set of weight training is defined as the number of times at least one weight training occurs between two stationary states, The number of groups trained by the accumulated weight and the number of times the weight training is recorded, the number of groups of weight training and the number of times of each group are obtained; and a mobile terminal including a wireless receiving unit and a recording unit, the wireless receiving unit and the The wireless transmitter is wirelessly connected, so that the mobile terminal receives data of the retraining weight, the number of groups of motion, and the number of times of each group sent by the wireless transmitter, and stores the data to the recording unit.

After the low-pass filtering process, the acceleration detected in the range of 9.8m/s ² plus or minus 0.3m/s ² exceeds 0.5 seconds, and the weight detected by the latch reaches a heavy weight; the history calculation is to measure the acceleration sensor. The obtained acceleration value that changes with time is calculated as a processing value by second-order low-pass filtering, and an upper edge value of 10.1 m/s ² and a lower edge value of 9.4 m/s ^{2 are set} , when the pin is detected. When the weight is zero, it is a static state, and the processing value is increased to pass the upper edge value and then decreased to the number of times the weight is trained by the lower edge value; when the static state is accumulated twice, the processing value is increased to pass the The upper edge value is then reduced to the number of times the group weight training is performed by the number of times of the lower edge value; a group of weight training is defined as the number of times at least one weight training occurs between two stationary states, and the weight training is performed by the accumulated weight. The number of groups and the number of times each group of weight training is recorded, the number of groups of weight training and the number of times of each group are obtained; data of the weight of the retraining weight, the number of groups of weight training, and the number of times of each group are stored to the recording unit.

When the counterweight adjustment lever and the plurality of weight plates above the selected weight plate are repeatedly pulled up, the latch senses the force generated by the movement of the selected weight plate and the plurality of weight plates above it. During the process, the acceleration sensor also senses the acceleration of the bolt rising or falling, and the data that is changed by the latch and the acceleration sensor over time is calculated by the microcontroller, or the data is wirelessly transmitted. To a computer or mobile terminal to perform calculations, you can get data such as retraining weight, number of movements, and number of times per group.

Referring to the preferred embodiment shown in FIG. 1 and FIG. 2, the present invention provides a weighting device wisdom plug A for a fitness equipment, the structure comprising a latch 10, a latch cap 20, a circuit structure 30, and a level 40. among them:

The pin 10 is a load pin and is sized to be inserted into the pin hole of the weight plate of the exercise equipment, the pin 10 having both ends 11 at opposite ends.

The latch cap 20 is disposed at one end portion 11 of both end portions 11 of the plug pin 10.

The circuit structure 30 is disposed in the latch cap 20 and includes a microcontroller 31 (MCU) and an acceleration sensor 32 electrically connected to the microcontroller 31, an electronic gyroscope 34, and a wireless device. The transmitter 33, wherein the microcontroller 31 integrates functions such as a central processing unit, a random access memory, a read-only memory, an input/output, a digital/analog conversion, and the like, and can perform arithmetic processing, memory storage, input/output, and the like. Control, the latch 10, the acceleration sensor 32, and the wireless transmitter 33 are electrically coupled to the microcontroller 31, respectively.

The acceleration sensor 32 is a uniaxial acceleration gauge whose direction of the predetermined sensation side acceleration is an up and down direction. When the position of the acceleration sensor 32 deviates from the position in the sense up and down direction, the electronic gyro 34 can measure The angle at which the acceleration sensor 32 is deviated, at which time the value detected by the acceleration sensor 32 can be corrected by the cheap angle detected by the electronic gyroscope 34, and the positional deviation acceleration sensor 32 is The measured acceleration value is corrected to the acceleration value in the up and down direction. The acceleration sensor 32 may be a multi-axis acceleration gauge in addition to the single-axis acceleration gauge, and when the direction of the acceleration of the acceleration sensor 32 is shifted in the up-and-down direction, even if the electronic gyroscope 34 is not used, The angle of the acceleration sensor 32 can still be calculated by the component of the gravity acceleration measured by the multi-axis acceleration gauge, and the acceleration value measured by the acceleration sensor 32 of the offset angle is corrected to the acceleration in the up and down direction. Value.

The wireless transmitter 33 is a Bluetooth module that can be wirelessly connected to other wireless receiving units, and can measure the data measured by the latch 10, the acceleration sensor 32, and the electronic gyro 34, or the microcontroller 31 can The result of the pin 10, the acceleration sensor 32 or the electronic gyroscope 34 is sent out.

The level 40 can be an electronic or bubble level, and the level 40 is coupled to the latch cap 20. The level 40 is disposed in a horizontal direction perpendicular to the direction in which the acceleration sensor 32 is intended to sense the acceleration, and is corrected by the level 40. The function allows the user to position the position of the weight of the fitness equipment counterweight wisdom pin A such that the acceleration sensor 32 senses the direction of the acceleration in accordance with the up and down direction of the predetermined detection acceleration.

When the fitness equipment weighting plug A of the present invention is used, as shown in FIG. 1 to FIG. 4, the latch cap 20 is hand-held, and the latch 10 is inserted into the latch of the weighting device 50 of the fitness equipment in a selected manner. The hole 51 and the corresponding hole 53 of the weight adjusting rod 52 pass through the horizontal state displayed by the level 40, and rotate the position of the pin 10 and the latch cap 20 to the direction of the sensing acceleration of the acceleration sensor 32 to meet the predetermined detection acceleration. Up and down direction.

When the user operates the fitness equipment for weight training, the weight adjusting rod 52 and the plurality of weight plates 50 above the selected weight plate 50 are repeatedly pulled up and down together. As shown in FIG. 5, the plug 10 of the present invention is A load-bearing pin has annular grooves formed on both sides of the middle, and a strain gauge 101 (Strain gauge) is respectively disposed at each groove, which can be used for measuring the interlacing of the middle and the front and rear sides of the pin 10 The shear force generated by the force of the pin 10 is supported by the through hole 53 of the weight adjusting lever 52, and the front and rear sides of the pin 10 are subjected to the downward weight of the weight plate 50, and the pin 10 of the load pin can feel The weight of the selected weight plate 50 and the plurality of weight plates 50 above it is measured, plus additional force due to the acceleration of the up and down movement. The acceleration sensor 32 also senses the acceleration of the bolt 10 ascending or descending with the weight adjustment lever 52 and the plurality of weight plates 50 during the operation of the fitness equipment by the user, the latch 10 and the acceleration sensor 32. The data sensed by the electronic gyroscope 34 can be subjected to arithmetic processing by the microcontroller 31, and the result of the arithmetic processing performed by the microcontroller 31 is sent out to the computer or mobile terminal for storage by the wireless transmitter 33. Or, the data sensed by the plug 10, the acceleration sensor 32 and the electronic gyroscope 34 can also be directly sent out to the computer or the mobile terminal for processing and storage for display or review by the wireless transmitter 33.

In order to record and calculate the data sent by the aforementioned fitness equipment weight piece wisdom plug A, as shown in FIG. 1 and FIG. 6, the invention is constructed with the fitness equipment weight piece wisdom plug A as a fitness equipment weight piece wisdom plug. The recording system, in which the fitness equipment weight piece wisdom plug A is inserted into one of the weights 50 and the weight adjustment rod 52 of the sports equipment, and the level 40 is used to correct the position of the acceleration sensor 32, so that the position of the acceleration sensor 32 is corrected. The position conforms to a preset position for sensing the acceleration in the up and down direction (if the angle of the acceleration sensor 32 is still offset, the electronic gyroscope 34 can be used to correct the value measured by the acceleration sensor 32). When the user operates the exercise equipment in a standard motion, the action flow of the latch 10 ascending or descending with the weight adjustment lever 52 and the plurality of weight plates 50 is as shown in the flowchart of FIG. 7, which are respectively described as follows:

Resting state: When the latch 10 is inserted into the weight plate 50 and the weight adjusting lever 52, the position of the latch 10 is stationary and does not bear the weight of the weight plate 50, and the weight measured by the plug 10 is zero. The acceleration measured by the sensor 32 has only a gravitational acceleration of 9.8 m/s ² , at which time the pin 10 is in a stationary state.

Ascending state: The latch 10 rises along with the weight adjusting lever 52 and the plurality of weight plates 50, and opens a new set of fitness movements or increases the movement of the same group of fitness exercises. As shown in FIG. 8, the time and acceleration coordinate map of the rising operation of the analog plug 10 have the horizontal axis as time, the vertical axis as acceleration, and the acceleration downward. In order to avoid the processing of noise affecting data, the acceleration value measured by the acceleration sensor 32 as a function of time is calculated as a processing value by second-order low-pass filtering, and an upper edge value of 10.1 m/s ^{2 is set} . When the acceleration value detected by the sensor 32 is increased to the upper edge value, it indicates that the pin 10 is about to reach the highest point, and the processing value of the acceleration sensor 32 measured in the early stage of the rising process of the pin 10 is gradually increased to 10.1. m/s ² , at this point we mark the occurrence of annotation A, that is, the acceleration passes the upper edge value. The acceleration measured by the acceleration sensor 32 at the later stage of the rising process of the plug 10 is gradually reduced to below the gravitational acceleration. When the pin 10 is raised to the position of the top dead center of the weight training, the acceleration sensor 32 is measured. The measured value will increase to approach the gravitational acceleration of 9.8 m/s ² .

Top dead center: This point is defined as the highest point at which the pin 10 and each weight plate 50 move, and is one of the dynamic stop states. However, since most users stop at this point for a very short time, it is not suitable for measuring the weight of all the weight plates 50 brought up by the plug 10, that is, the weight of the heavy training.

Downward state: the latch 10 is downward with the weight adjusting lever 52 and the plurality of weight plates 50. The time and acceleration coordinate diagram of the analog plug 10 as shown in FIG. 9 are downward, and the horizontal axis is time. The axis is acceleration and the acceleration is positive downward. In order to avoid the processing of noise affecting data, the acceleration value measured by the acceleration sensor 32 as a function of time is calculated as a processing value by second-order low-pass filtering, and the edge value is set to 9.4 m/s ² when the pin 10 is used. When the detected acceleration value is reduced to the lower edge value, it indicates that the pin 10 is about to reach the lowest point, and the processing value measured by the acceleration sensor 32 in the previous process of the plug 10 is gradually reduced to 9.4 m/ s ² , at this time, the acceleration passes the lower edge value; we check whether the annotation A is marked before this, if any, the annotation B is marked, and the number of repetitions of the weight training is increased by one; if the processing value is reduced to At the time of the margin, before the note A is not marked, we also do not mark the note B. Because of the characteristics of the fitness equipment, the pin 10 and the weight plate 50 must first move up and then move down, so it is used for calculation. The note A of the weight training time and the note B need to be sequentially generated. The repeated action of the weight training can be judged by the sequential appearance of the note A and the note B. Otherwise, the noise is regarded as a noise. For example, if the annotation A and the annotation B do not occur in sequence, the annotation BA, the annotation AA, and the annotation BB are not counted; if the annotation B has not occurred, the annotation A occurs several times, and only the single annotation A is noted. ,vice versa.

Determining whether it is a dynamic stop: the bottom dead point is a set of weight training rooms or the weight training is just started, the bolt 10 and the weight plate 50 are moved downward to the lowest point of the weight plate 50 that stops but does not touch the bottom, that is, The short rest stop point after the end of the user's weight training is repeated, and the weight of the weight plate 50 lifted by the user acts on the pin 10, and the weight plate 50 is also non-moving. In this state, at this time, the weight of all the weight plates 50 brought up by the plug 10 is measured, and the weight of the heavy training is obtained. Analyzing dead bolt 10 is located in the manner that the acceleration sensor 32 measured values after the low-pass second order filter processing in 9.8m / s ² negative 0.3m / s ² travel than 0.5 seconds, i.e., determines that the pin 10 is located at the bottom dead center. At this time, the weight measured by the pin 10 is the weight of the retraining weight, and in the step of judging whether or not the movement is stopped, if it is determined to be the bottom dead center, the step of returning to the ascending state is returned. If the weight measured by the pin 10 is zero, that is, the pin 10 is judged to be in a static stop state, at this time, the number of exercise groups is calculated by adding 1 and returning to the above-mentioned stationary state, waiting for the next ascending state step to be turned on. The set of new exercise movements, a set of weight training is defined as the repeated action of at least one weight training between two stationary states.

According to the action flow of the above-mentioned plug 10 and the judgment method of each flow, the fitness equipment weighting wisdom plug recording system includes: a fitness equipment weighting piece wisdom plug A, and the structure and the aforementioned fitness equipment weight piece wisdom plug A Similarly, the microcontroller 31 receives the data sensed by the latch 10, the acceleration sensor 32, and the electronic gyroscope 34 to perform a weight calculation, a history calculation, and a fitness time calculation. , wherein: the latch 10 is raised or lowered with the weight adjusting lever 52 and the plurality of weight plates 50, and the manner of determining that the motion reaches the stop is that the value measured by the acceleration sensor 32 is second-order low-pass. After the filtering process, the acceleration stays in the interval of 9.8 m/s ² plus or minus 0.3 m/s ² for more than 0.5 seconds, at which time the pin 10 is subjected to the weight of only the selected weight plate 50 together with the weight of the plurality of weight plates 50 above. The weight calculation is performed in the state where the weight detected by the plug 10 is not zero, and the value measured by the acceleration sensor 32 is calculated by the second-order low-pass filtering, and the acceleration is 9.8 m/s ² plus or minus 0.3. m / s ² area Residence than 0.5 seconds when the pin 10 to detect the weight of a retraining derived by weight.

Since the acceleration sensor 32 performs a plurality of ascending and descending cycles with the weight adjustment lever 52 and the plurality of weight plates 50, the number of occurrences of the annotation A and the annotation B, that is, the number of times the weight training is completed. And each time the weight measured by the pin 10 is zero, it is a static state, the first stationary state represents the beginning of each group of weight training, and the second stationary state represents the end of each group of weight training, a set of weights. Training is defined as the number of times at least one weight training occurs between two stationary states. 10 to FIG. 14 are respectively the time and acceleration coordinate maps of the foot presses of the user who are equipped with the fitness device weights wisdom plug A, and are calculated by second-order low-pass filtering. After filtering the dithered high frequency noise in the upper graphs of FIG. 10 to FIG. 14, the time and acceleration coordinate maps of the lower graphs of FIGS. 10 to 14 are obtained.

The history calculation is based on the second-order low-pass filter calculation, and the noise in the acceleration value measured by the acceleration sensor 32 is filtered into a processing value, and an upper edge value of 10.1 m/s ² and the lower edge value are set. 9.4m/s ² , the time when the plug 10 is measured and the weight is zero is calculated, and the time when the weight of the plug 10 is zero is calculated twice, and the acceleration of the processed value exceeds the upper edge value and is lower than The number of repetitions of the lower edge value, the number of repetitions is added to obtain the number of exercise activities of each group, thereby obtaining the number of exercise groups and the number of times of each group; the exercise time calculation is to accumulate the time of all non-stationary states. A fitness time, such as the time of non-stationary state of the day, is the fitness time of the day. The wireless transmitter 33 sends out the data of the retraining weight, the number of fitness exercises, the number of times of each group, and the fitness time.

A mobile terminal 60 includes a wireless receiving unit 61 and a recording unit 62. The wireless receiving unit 61 is a Bluetooth receiver and is wirelessly connected to the wireless transmitter 33, so that the mobile terminal 60 receives the wireless transmitter 33. The data of the weight training, the number of exercise groups, the number of times of each group, and the exercise time are stored, and the data is stored in the recording unit 62.

The system of the present invention can automatically record the weight of the re-training in the recording unit 62 of the mobile terminal 60 when the weight training of the fitness equipment is used to replace the bolt of the fitness equipment with the weight of the fitness equipment. The number of groups of fitness exercises and the number of times of each group, the data of fitness time. These data can provide users with queries to plan the weight training program, increase or decrease the number of re-training weights or movements, the number of times, or as a weight training. The results are compared with peers, and mutual incentives increase the motivation of the movement.

The weight of the retraining exercise, the number of sets of exercise, the number of times of each group, and the exercise time are measured by the microcontroller 31, and the pin 10, the acceleration sensor 32, and the electronic gyroscope 34 can be sensed. The method of wirelessly transmitting the data to the mobile terminal 60, performing the weight calculation and the history calculation by the mobile terminal 60, and recording the calculation result in the recording unit 62 of the mobile terminal 60 for subsequent inquiry or analysis.
