Description

Technical Field

[0001] The present invention relates to the technical field of smart swimming bracelets, in particular to a multifunctional smart swimming bracelet and a swimming status monitoring device. Background Art

[0002] With the continuous development of wearable devices and the continuous advancement of related technologies, smart bracelets are used by more and more people. By using smart bracelets, a series of relevant data such as the user's fitness effect, sleep quality, diet arrangements and habits can be recorded, and these data can be synchronized to the user's mobile terminal device. The terminal device may give relevant suggestions based on its own "analysis function" to guide healthy life through data. At the same time, by integrating various sensors on the smart bracelet, the wearer's physiological parameters can be monitored, such as heart rate monitoring through photoelectric sensors and body temperature monitoring through thermistors. In addition, by adding a waterproof function to the smart bracelet, the user can wear the bracelet to swim in the shallow sea or river, overcoming the defect that traditional pedometers cannot track swimming exercises.

[0003] With the continuous expansion of the functions of wearable devices, the human body state can be judged by monitoring the human physiological state through smart bracelets. Therefore, in the prior art, by integrating the swimming status monitoring function in the smart bracelet, the user's safety status can be judged. When there is a safety problem, the smart bracelet will automatically send a corresponding distress signal to the management end. At the same time, the wearer can also actively send a distress signal when he finds that there is a safety problem. According to the position coordinate signal of the smart bracelet, it can assist the lifeguard to reach the user's location in time.

[0004] Both the wearer's active distress signal and the smart bracelet's automatic distress signal when it detects a safety issue are active distress signals of the smart bracelet. When this method is used in places such as swimming pools, there are the following safety issues: First, when the smart bracelet malfunctions or runs out of power, it can no longer perform the function of safety monitoring. At this time, if the user has a drowning problem, his or her safety status cannot be effectively monitored. Secondly, after the bracelet sends a distress signal, there is a risk that the signal cannot be received by the management end due to problems such as long signal distance or signal blocking, which will still affect the user's safety distress call.

[0062] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0063] See also Figure 1 , Figure 2 As shown, in one embodiment, a multifunctional intelligent swimming wristband is provided, wherein the wristband is communicatively connected to a swimming status monitoring device, and the function of monitoring user safety is realized by intelligent communication between the wristband and the swimming status monitoring device. Specifically, the wristband includes a status monitoring module, an analysis module, a rescue module and a passive feedback module, wherein the status monitoring module can monitor the user's status information, and can monitor the user's motion status and physiological parameters by using components such as a gyroscope, an acceleration sensor, and a photoelectric sensor provided on the wristband, and the analysis module can analyze the status information monitored by the status monitoring module, and then can judge the user's safety status through analysis, and when it is judged that the safety status is abnormal, the rescue module in the wristband will send a distress signal, and at the same time, when the user performs a corresponding active operation on the wristband, the rescue module will also send a request signal, therefore, this embodiment can send a distress signal in an automatic and active manner through the monitoring of the user's status by the wristband.

[0064] At the same time, the passive feedback module in this embodiment can be paired and connected with the swimming status monitoring device. After the pairing connection, the swimming status monitoring device will send verification information at specific time intervals, and the passive feedback module will send a feedback signal to the receiving swimming status monitoring device after receiving the verification information each time. Therefore, the swimming status monitoring device can judge the communication status of the bracelet through the reception status of the feedback signal, and then judge the user's status. When the communication status of the bracelet is not good or the content of the feedback signal indicates that the user has a safety problem, a distress signal will be automatically generated. Therefore, this embodiment uses the bracelet to passively send information and the swimming status monitoring device to obtain its status to judge the user's safety status. Regardless of whether the status of the bracelet is normal, a distress signal can be sent when the user has a safety problem to ensure that the user is rescued in time.

[0065] As an implementation mode of the present invention, the status signal in this embodiment includes user motion data and user physiological parameter data; wherein, the user motion data includes real-time change data of the user's arm swing motion trajectory; the user physiological parameter data includes real-time change data of the user's heart rate; therefore, through comprehensive analysis of the user motion data and the user physiological parameter data, a more accurate judgment can be made on the user's safety, thereby reducing the chance of misjudgment.

[0066] Specifically, the present embodiment provides a method for judgment by an analysis module. First, a curve of the change of swing amplitude over time is established according to the real-time change data of the swing arm motion trajectory, and the curve transformation image information is input into the analysis model for analysis: if the analysis result is normal, it means that the movement state of the user's arm is normal, and the user's safety state is judged to be normal; if the analysis result is abnormal, it means that the user is currently in a non-standard motion state. At this time, the analysis is performed in combination with the user's heart rate data, and the heart rate data is compared with the preset standard: if the user's heart rate meets the preset standard, it means that the current user's heart rate state is normal. At this time, a safety confirmation message is generated to the user. If the user replies to the safety confirmation message within a specific time period, the user is judged to be in a safe state; otherwise, the user is judged to be in a dangerous state; if the user's heart rate does not meet the preset standard, the user is judged to be in a dangerous state. Therefore, the present embodiment can accurately analyze and judge the user's safety state through the analysis and judgment process of the user's motion data and heart rate data, and can then send a distress signal in time when the user is at safety risk.

[0067] It should be noted that the analysis model in this embodiment uses the user's motion data in normal and abnormal states as positive samples and negative samples respectively, and is generated through machine learning. It can judge whether the user's motion state is standard. In addition, the sending of safety confirmation information can be carried out by the vibration of the bracelet, the lighting of the screen or the sound of a dialog box to confirm whether it is safe. Obviously, when the user replies that it is safe, it is judged that the user is in a safe state. If the user replies that it is not safe or does not reply, it means that the user is at security risk.

[0068] As an implementation mode of the present invention, there is an active rescue bracelet in the prior art. This kind of bracelet can be opened under the premise of active operation by the user to achieve the function of temporary rescue for the user. However, in some emergency situations, the user cannot actively operate the rescue bracelet in time or effectively, so it is necessary to realize the automatic opening of the rescue bracelet. This method requires integrating various chips, sensors and other components in the rescue bracelet. In addition, this kind of rescue bracelet is not suitable for daily use, resulting in poor applicability of this kind of rescue bracelet. Therefore, please refer to Figure 3 , Figure 4As shown, the present embodiment provides a rescue bracelet, which includes an expansion connection module, and the expansion connection module is communicatively connected to an emergency rescue device 1, wherein the rescue module of the bracelet is also used to send a control instruction to the expansion connection module when it is started, so as to control the emergency rescue device 1 to start. It can be seen that the present embodiment connects the emergency rescue device 1 by expansion, and connects the two by communication. The specific connection method includes but is not limited to communication cables, Bluetooth and WiFi. Therefore, when the user has a need to swim, the emergency rescue device 1 can be expanded and connected to the bracelet, and the emergency rescue device 1 can be automatically opened through the monitoring of the user's safety status by the bracelet, and the emergency rescue effect for the user can be achieved through the emergency rescue device 1. When there is no need to swim, the emergency rescue device 1 can be removed to ensure that the bracelet can be used normally in daily life. At the same time, for the emergency rescue device 1 that can be expanded and used, it does not need to be provided with a sensor component and a chip with strong processing capability, so the cost is low. Therefore, the present embodiment improves the applicability of the bracelet by expanding the connection between the emergency rescue device 1 and the bracelet.

[0069] As an implementation of the present invention, this embodiment provides a specific structural implementation of the emergency rescue device 1 in a wristband, please refer to Figure 3 , Figure 4 As shown, the emergency rescue device 1 includes a fixing strap 11, on which a shell 12 is arranged; an airbag 14, a control module and a communication module are arranged in the shell 12, and an inflatable component 13 is arranged on one side of the shell 12. The communication module is used to receive control instructions and send them to the control module. Therefore, when the control module receives the control instruction, it will control the inflatable component 13 to inflate the airbag 14. Specifically, the inflatable component 13 is connected to the airbag 14 and compressed gas is stored in the inflatable component 13 in advance. When the control module receives the control instruction, the gas in the inflatable component 13 is released, thereby filling the airbag 14 with gas. The airbag 14 filled with gas can provide a certain buoyancy support to the user in the water, thereby achieving the effect of temporary rescue.

[0070] Furthermore, the emergency rescue device 1 in this embodiment also includes an active trigger component 15, which is arranged on one side of the inflatable component 13, and is used to control the control module according to the user's active operation to make the inflatable component 13 inflate the airbag 14. Therefore, by arranging the active trigger component 15 on the emergency rescue device 1, the user can actively open the inflatable component 13 when the bracelet does not detect any safety problems, thereby achieving the effect of user's active self-rescue, thereby ensuring the user's safety under different conditions.

[0071] As an implementation mode of the present invention, the analysis module in this embodiment can also analyze and evaluate the standard of the user's exercise according to the user's exercise data. Figure 5As shown, this embodiment provides an evaluation method, step S1, obtaining the user's preset information, the preset information includes the user's height and swimming style; due to different swimming types, the swimmer's posture and movements will be different, and at the same time, due to different height levels of users, their movement data will also be different, so by obtaining the user's height and swimming style, and then performing step S2, selecting the corresponding arm swing movement trajectory standard according to the user's height and swimming style; that is, the corresponding evaluation standard can be selected according to the different users and the different adaptability of the swimming style, wherein the selection of the height is determined according to the range of the user's height, and the swimming style includes butterfly stroke, freestyle, backstroke and breaststroke, which are determined according to the user's selection. In addition, due to the large difference in the movement speed of different people, therefore, in step S3 of this embodiment, The frequency of the user's swing amplitude changing curve over time is standardized and adjusted, and the adjusted changing curve is compared with the standard arm swing motion trajectory. The user's swimming style standard is evaluated according to the degree of overlap. This method can standardize the frequency of the user's swing amplitude changing curve over time, so that the user's motion data and the standard maintain the same frequency, which makes it easier to compare and analyze the user's movements. It should also be noted that the comparison of the degree of overlap described in this embodiment is the degree of overlap between the user's arm swing motion trajectory and the standard motion trajectory. When the user's arm swing motion trajectory is less than or equal to a specific threshold from the standard motion trajectory, the two are considered to overlap. When it is greater than the threshold, the two are considered to not overlap. The user's swimming style standard is evaluated according to the proportion of overlapping intervals in the entire exercise round of the user.

[0072] The present embodiment provides a swimming status monitoring device, which includes a pairing module, an information transmission module and a wristband status monitoring module; wherein the pairing module is used for pairing with a wristband; the information transmission module is used for sending verification information to the paired wristband at specific intervals, and receiving a feedback signal from the corresponding wristband, and sending the feedback information to the wristband status monitoring module; the wristband status monitoring module is used for automatically generating a distress signal according to the content of the feedback signal and the receiving status. Therefore, by sending verification information and receiving feedback signals from the wristband at intervals through the swimming status monitoring device, the wristband can be monitored, and not only can it be determined whether the user has a safety problem based on the information of the feedback signal, but also in the case of wristband failure, transmission signal obstruction or the wristband leaving the monitoring range of the device, the user's safety status can be judged in a timely manner, thereby improving the comprehensiveness of user safety protection.

[0073] As an implementation mode of the present invention, the steps of generating a distress signal in this embodiment are: first, determine whether a feedback signal is received; if received, analyze the user signal: if the feedback signal content contains distress information, it means that the user has a safety problem, so a distress signal is generated immediately; if there is no distress information in the feedback signal content, it means that the user is safe and within the monitoring range, so the user is judged to be safe; if no feedback signal is received from the bracelet, it means that the bracelet is at risk of being out of monitoring. At this time, adjust the frequency of sending verification information, send the verification information again and actively communicate. If the feedback signal is still not received and the active communication fails , indicating that the user has left the monitoring range or the bracelet has a malfunction, so a distress signal is sent to promptly remind the management staff to confirm the user status. When a feedback signal is received or active communication is connected, it is determined whether to send a distress signal based on the feedback signal or active communication information. If the feedback signal or active communication information contains relevant information that the user has a safety problem, a distress signal is sent, otherwise it means that the user is safe and no distress signal is sent. Therefore, through the generation step of the distress signal, the user's status can be intelligently judged according to the user's actual situation, and then it is determined whether to send a distress signal, thereby realizing comprehensive monitoring of users wearing bracelets.

[0074] The above is a detailed description of an embodiment of the present invention, but the content is only a preferred embodiment of the present invention and cannot be considered to limit the scope of implementation of the present invention. All equivalent changes and improvements made within the scope of the present invention should still fall within the scope of the patent coverage of the present invention.
