Description

Technical Field

[0001] The invention relates to the technical field of automatic timing of swimming competitions, and in particular to a sensor for a swimming timing touch panel. Background Art

[0002] The swimming timing touch panel is used in swimming competitions and training. When a swimmer reaches the end of the track, the swimmer touches the timing touch panel, and the touch panel displays the athlete's results through the display screen. It is an automated timing device for swimming events. Ordinary timing touch panels only have the function of recording time. During swimming training, athletes will open up a large distance in the process of pushing off the wall and turning. Fast turning will improve results. The pressure applied by athletes on the touch panel and the contact area during the turning process have a great influence on the turning time. The coach can guide the athlete's technical movements by analyzing the pressure and contact area, so as to improve the athlete's competition results.

[0003] Chinese patent application publication number: CN108579061A discloses an elastic tube type swimming timing touch panel, including a frame group, an elastic tube assembly, an elastic support assembly, an elastic skin and screws, and is characterized in that the elastic tube assembly is connected to the frame group by screws, the elastic support assembly is contact-connected with the elastic tube assembly, and the elastic skin is contact-connected with the elastic support assembly; the fluororubber tube in the elastic tube assembly has high sensitivity, uniform force in the length direction, no trigger blind area, a single-point press can also generate a trigger signal, the trigger force is lower, and the trigger sensitivity is higher; the U-profile protects the fluororubber tube from overload, and the fluororubber tube has better reliability; the touch panel has increased transverse and longitudinal structural strength, lighter overall weight, better impact and vibration resistance, and meets the requirements of transportation and use and maintenance.

[0004] However, the above method has the following problems:

[0005] The timing touch panel cannot record the pressure applied by the athlete on the timing touch panel and the contact area with the timing touch panel, and cannot determine the athlete's turning technical action by analyzing the pressure and contact area. Summary of the invention

[0006] To this end, the present invention provides a sensor for a swimming timing touch pad, so as to overcome the problem in the prior art that the timing touch pad cannot record the pressure applied by the athlete on the timing touch pad and the contact area of ​​the timing touch pad, and cannot determine the athlete's turning technical action by analyzing the pressure and the contact area, thereby resulting in a decrease in the accuracy and practicality of the timer in determining the athlete's entire turning action process.

[0007] To achieve the above object, the present invention provides a sensor system for a swimming timing touch pad, comprising:

[0008] A contact module, used to collect and generate corresponding swimming data, wherein the swimming data includes time, pressure and contact area;

[0009] A pressure module connected to the contact module, used for comparing the pressure value collected by the contact module and transmitting the pressure value and a start signal;

[0010] Wherein, the start signal is a signal for driving other modules to start recording the swimming data, and the pressure value includes a hand pressure value and a foot pressure value;

[0011] A time module, which is connected to the contact module and the pressure module respectively, and is used to transmit the turning time and action time collected by the contact module when receiving the start signal;

[0012] an area module, which is connected to the contact module and the pressure module respectively, and is used to transmit the contact area value collected by the contact module when receiving the start signal, wherein the contact area value includes the hand contact area value and the foot contact area value;

[0013] an analysis module, which is connected to the pressure module, the time module and the area module respectively, and is used to receive the pressure value transmitted by the pressure module, the turning time transmitted by the time module and the contact area value transmitted by the area module, and compare the corresponding pressure values ​​and the contact areas within several turning times to obtain the hand contact area value corresponding to the maximum hand pressure value and the foot contact area value corresponding to the maximum foot pressure value;

[0014] Wherein, a single turning time includes an action of a hand touching the contact module and an action of a foot touching the contact module, and the action of the hand touching the contact module is completed before the action of the foot touching the contact module.

[0015] Furthermore, the pressure module is used to compare whether the pressure value collected by the contact module reaches a set value;

[0016] If the pressure value is greater than or equal to the set value, the pressure value and a start signal are transmitted;

[0017] The set value is positively correlated with the impact force of water waves in the swimming pool hitting the contact module.

[0018] Further, the time module receives the moment when the hand touches the contact module, the moment when the hand leaves the contact module, the moment when the foot touches the contact module, and the moment when the foot leaves the contact module;

[0019] The turning time is the duration from the moment when the hand touches the contact module to the moment when the foot leaves the contact module;

[0020] The action time includes the time when the hand acts on the contact module and the time when the foot acts on the contact module;

[0021] The time when the hand acts on the contact module is the time from the moment when the hand touches the contact module to the moment when the hand leaves the contact module;

[0022] The time that the foot acts on the contact module is the duration from the moment when the foot touches the contact module to the moment when the foot leaves the contact module.

[0023] Furthermore, the area module records the maximum touch area of ​​the contact module in a single touch, and transmits it to the analysis module:

[0024] The single touch includes a single touch by hand and a single touch by foot.

[0025] Furthermore, the contact module is connected to the timing touch panel, including:

[0026] A pressure sensing unit, which is used to sense the pressure acting on the timing touch plate;

[0027] A time acquisition unit, which is used to record the moment of each pressure change;

[0028] The area calculation unit is used to sense the range of pressure acting on the timing touch panel and calculate the area of ​​the range.

[0029] Furthermore, the analysis module includes:

[0030] A turning analysis unit, which is used to compare the several turning times collected by the contact module and obtain the contact area corresponding to the minimum turning time;

[0031] The action analysis unit is used to compare the several action times collected by the contact module and obtain the contact area corresponding to the minimum action time.

[0032] Furthermore, upon receiving the pressure values ​​transmitted by the pressure modules, the turning times transmitted by the time module, and the contact area values ​​transmitted by the area module, the analysis module associates the pressure values ​​corresponding to each turning time with each contact area one by one.

[0033] Furthermore, the analysis module classifies the pressure values ​​and the contact areas within the corresponding turning times into two categories: hand contact and foot contact.

[0034] Furthermore, the analysis module compares the pressure values ​​of the hand contact and the foot contact respectively to obtain the maximum pressure value of the hand contact class and the maximum pressure value of the foot contact class, and obtains the maximum contact area of ​​the hand contact class and the maximum contact area of ​​the foot contact class corresponding to the maximum pressure value of the hand contact class.

[0035] Compared with the prior art, the beneficial effect of the present invention is that by collecting the time, pressure and contact area acting on the timing touch pad, the technical characteristics of the athletes are comprehensively analyzed, which has the advantages of being simple and reliable, and further improves the accuracy and practicality of the timing touch pad.

[0036] Furthermore, by setting a pressure module, the technical solution collects data without being affected by water waves in the swimming pool, and collects various data more accurately. While improving the anti-interference of the collection, it further improves the accuracy and practicality of the timing touch panel.

[0037] Furthermore, the technical solution sets up an analysis module to correspond and classify the collected data, which effectively improves the clarity and comprehensiveness of the analysis data while further improving the accuracy and practicality of the timing touch panel.

[0038] Furthermore, the technical solution classifies and analyzes the parameters of the hands and feet to more accurately obtain the athlete's technical movements, and at the same time improves the technical movements more accurately and specifically, thereby improving the athlete's performance and further improving the accuracy and practicality of the timing touch panel.

For those skilled in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0049] See also Figure 1 As shown, it is a schematic diagram of the structure of the sensor system of the swimming timing touch pad of the present invention. A sensor system of the swimming timing touch pad includes:

[0050] A contact module, used to collect and generate corresponding swimming data, wherein the swimming data includes time, pressure and contact area;

[0051] A pressure module, which is connected to the contact module, is used to compare the pressure value collected by the contact module and transmit the pressure value and a start signal;

[0052] The start signal is a signal that drives other modules to start recording swimming data, and the pressure value includes the hand pressure value and the foot pressure value;

[0053] A time module, which is connected to the contact module and the pressure module respectively, and is used to transmit the turning time and action time collected by the contact module when receiving the start signal;

[0054] An area module, which is connected to the contact module and the pressure module respectively, and is used to transmit the contact area value collected by the contact module when receiving the start signal, wherein the contact area value includes the hand contact area value and the foot contact area value;

[0055] An analysis module, which is connected to the pressure module, the time module and the area module respectively, and is used to receive the pressure value transmitted by the pressure module, the turning time transmitted by the time module and the contact area value transmitted by the area module, and compare the corresponding pressure values ​​and contact areas within a number of turning times to obtain the hand contact area value corresponding to the maximum hand pressure value and the foot contact area value corresponding to the maximum foot pressure value;

[0056] Among them, a single turning time includes an action of a hand touching the contact module and an action of a foot touching the contact module, and the action of the hand touching the contact module is completed before the action of the foot touching the contact module.

[0057] Specifically, by collecting the time, pressure and contact area acting on the timing touch pad, the technical characteristics of the athletes are comprehensively analyzed. It has the advantages of being simple and reliable, and further improves the accuracy and practicality of the timing touch pad.

[0058] Specifically, the pressure module is used to compare whether the pressure value collected by the contact module reaches the set value;

[0059] If the compared pressure value is greater than or equal to the set value, the pressure value and the start signal are transmitted;

[0060] Among them, the set value is positively correlated with the impact force of water waves hitting the contact module in the swimming pool.

[0061] It is understandable that for those skilled in the art, the impact force of water waves hitting the pressure module is the pressure generated by the water waves in the swimming pool hitting the contact module. The set value can be obtained by counting the values ​​of the water wave impact pressure sensor over a period of time through a pressure sensor set next to the swimming pool, which will not be elaborated here.

[0062] Example 1

[0063] In this embodiment, the set value is 0.5 Newton. When the pressure value collected by the contact module is 0.2 Newton, the pressure module does not act. When the pressure value collected by the contact module is 10 Newton, the pressure value is transmitted and a start signal is issued.

[0064] Specifically, by setting a pressure module, the collection parameters of this technical solution are not affected by the water waves in the swimming pool, and various data are collected more accurately. While improving the anti-interference of the collection, it further improves the accuracy and practicality of the timing touch panel.

[0065] Specifically, the time module receives the moment when the hand touches the contact module, the moment when the hand leaves the contact module, the moment when the foot touches the contact module, and the moment when the foot leaves the contact module;

[0066] The turning time is the time from the moment the hand touches the contact module to the moment the foot leaves the contact module;

[0067] The action time includes the time when the hand acts on the contact module and the time when the foot acts on the contact module;

[0068] The time when the hand acts on the contact module is the time from the moment when the hand touches the contact module to the moment when the hand leaves the contact module;

[0069] The time that the foot acts on the contact module is the time duration from the moment when the foot touches the contact module to the moment when the foot leaves the contact module.

[0072] At this time, the turning time is 5 seconds, the time that the hand acts on the contact module is 1 second, and the time that the foot acts on the contact module is 2 seconds.

[0073] Specifically, the area module records the maximum touch area of ​​the single touch contact module and transmits it to the analysis module:

[0074] Among them, single touch includes single touch of hand and single touch of foot.

[0075] Example 3

[0076] Based on the second embodiment, the present embodiment is different from the second embodiment in that when the hand touches the timing touch pad, the area calculator calculates the contact area to be 1 to 80 square centimeters, taking 80 square centimeters as the contact area; when the foot touches the timing touch pad, the area calculator calculates the contact area to be 1 to 100 square centimeters, taking 100 square centimeters as the contact area.

[0082] A turning analysis unit, which is used to compare several turning times collected by the contact module and obtain a contact area corresponding to the minimum turning time;

[0083] The action analysis unit is used to compare several action times collected by the contact module and obtain the contact area corresponding to the minimum action time.

[0084] Specifically, the technical solution sets up an analysis module to correspond and classify the collected data, effectively improving the clarity and comprehensiveness of the analysis data while further improving the accuracy and practicality of the timing touch panel.

[0085] Specifically, upon receiving pressure values ​​transmitted by several pressure modules, turning times transmitted by a time module, and contact area values ​​transmitted by an area module, the analysis module associates corresponding pressure values ​​within each turning time with each contact area.

[0086] Specifically, the analysis module classifies the pressure values ​​and contact areas within each corresponding turning time into two categories: hand contact and foot contact.

[0087] Specifically, the analysis module compares the pressure values ​​of hand contact and foot contact respectively to obtain the maximum pressure value of the hand contact class and the maximum pressure value of the foot contact class, and obtains the maximum contact area of ​​the hand contact class and the maximum contact area of ​​the foot contact class corresponding to the maximum pressure value of the hand contact class.

[0088] Specifically, the analysis module compares the time when the hand acts on the contact module and the time when the foot acts on the contact module, and obtains the minimum value and the corresponding contact area respectively.

[0089] Example 4

[0090] On the basis of Example 2, the present embodiment is different therefrom in that, during the process of turning 10 times, the analysis module compares the time used for the 10 turns, and obtains a minimum turning time of 2 seconds, corresponding to a hand contact area of ​​60 square centimeters, and a corresponding foot contact area of ​​80 square centimeters; the analysis module compares the time that the hand acts on the contact module 10 times, and obtains a minimum time that the hand acts on the contact module of 0.3 seconds, corresponding to a hand contact area of ​​70 square centimeters; the analysis module compares the time that the foot acts on the contact module 10 times, and obtains a minimum time that the foot acts on the contact module of 1.2 seconds, corresponding to a foot contact area of ​​60 square centimeters.
