Description

Technical Field

[0001] The present invention relates to the technical field of drowning prevention equipment, and in particular to a remote drowning prevention management method based on an drowning prevention collar, a computer program product and a system. Background Art

[0002] With economic development, people's living standards have gradually improved, and the demand for water sports has also gradually increased. Drowning accidents are prone to occur during water sports. To avoid drowning, people usually wear life jackets or life buoys, but life jackets and life buoys are filled with air or filled with floating objects, which are large in size and will affect the wearer's water sports.

[0003] There is an anti-drowning collar with an air bag and an air pump built in it, and an inflation button is arranged on the outer periphery of the collar. When the user is doing water sports, the anti-drowning collar is worn on the neck. Under normal circumstances, the air bag shrinks in the collar, making the collar smaller in size, which can reduce the impact on the wearer's water sports. When a drowning accident occurs, the user can press the inflation button to make the air pump built into the collar inflate the air bag. After the air bag is inflated, the collar is opened and wrapped around the user's neck, lifting the user's head to float on the water surface to prevent drowning.

[0004] In some specific places where water sports are organized, such as school swimming pools, athlete training pools, etc., athletes are uniformly required to wear anti-drowning collars. However, since the anti-drowning collars are worn around the neck, users will always feel a little uncomfortable after putting on the anti-drowning collars. Some people in these specific places may not wear anti-drowning collars for comfort, which may easily lead to drowning accidents. Currently, there is a lack of means to supervise whether people wear anti-drowning collars. Summary of the invention

[0005] The technical problem to be solved by the present invention is how to supervise whether a person wears an anti-drowning collar in a place where the person is required to wear the anti-drowning collar.

[0006] In order to solve the above technical problems, the present invention provides a remote drowning prevention management method based on an anti-drowning collar, which is applied to a background management end of a remote drowning prevention management system, and the background management end has established a remote communication connection with multiple anti-drowning collars. The remote drowning prevention management method includes the following steps:

[0007] S1. Obtain the number of athletes to be engaged in water sports input by the user;

[0008] S2. Receive the start signal of the anti-drowning collar that has established the remote communication connection, and record the number of start signals received;

[0009] S3. For the activated anti-drowning collar, receiving the pressure data and acceleration sensor data obtained within a preset time period after activation;

[0010] S4. Identify the number of anti-drowning collars being worn based on changes in pressure data and acceleration sensor data over time within a preset time period;

[0011] S5. Compare the number of athletes with the number of anti-drowning collars being worn, and determine whether there are athletes who do not wear anti-drowning collars based on the comparison results. If so, execute steps S6 and S7. If not, do not execute step S6 and only execute step S7;

[0012] S6. Issue a warning signal;

[0013] S7. Continue to detect whether a drowning signal is received from the anti-drowning collar being worn.

[0014] Furthermore, in step S4, if the pressure data and acceleration sensor data corresponding to a certain anti-drowning collar change continuously over time within a preset time period, it is recognized that the anti-drowning collar is being worn and used; if the pressure data or acceleration sensor data corresponding to a certain anti-drowning collar does not change continuously over time within the preset time period, it is recognized that the anti-drowning collar is not being worn and used.

[0015] Furthermore, in step S5, if the number of athletes is greater than the number of anti-drowning collars being worn, it is determined that there are athletes who do not wear anti-drowning collars; if the number of athletes is equal to the number of anti-drowning collars being worn, it is determined that there are no athletes who do not wear anti-drowning collars.

[0016] The present invention also provides a computer program product, comprising a computer program, which implements the steps of the above-mentioned remote drowning prevention management method when executed by a processor.

[0017] The present invention also provides a remote anti-drowning management system based on anti-drowning collars, including a background management terminal and multiple anti-drowning collars, wherein the background management terminal establishes a remote communication connection with the multiple anti-drowning collars, and the background management terminal includes an interconnected memory and a processor, wherein the memory stores the above-mentioned computer program product.

[0018] Furthermore, the anti-drowning collar includes a collar body, which has a compressed airbag, an air pump, an acceleration sensor, a wireless communication module and a controller built in the collar body, the air outlet of the air pump is connected to the compressed airbag, a power switch and an air pressure sensor are provided on the periphery of the collar body, and a closed seam that can be opened by the inflated compressed airbag is provided at the position corresponding to the compressed airbag, the power switch, the air pressure sensor, the air pump, the acceleration sensor and the wireless communication module are electrically connected to the controller respectively, and the anti-drowning collar establishes a remote communication connection with the background management end through the wireless communication module.

[0019] Furthermore, an inflation button is provided on the periphery of the collar body, and the inflation button is electrically connected to the controller. When the inflation button is pressed, an inflation signal is input to the controller, and the controller generates a drowning signal and sends it to the backend management terminal.

[0020] Furthermore, the power switch is arranged at the rear side of the collar body, and the air pressure sensor and the inflation button are arranged at the front side of the collar body.

[0021] The present invention has the following beneficial effects: the backend management end first obtains the number of athletes who are going to perform water sports, then receives the pressure data and acceleration sensor data of the activated anti-drowning collars, identifies the number of anti-drowning collars being worn and used according to the pressure data and the acceleration sensor data, and then compares the number of athletes with the number of anti-drowning collars being worn and used, so as to determine whether there are athletes who do not wear and use anti-drowning collars. If so, the backend management end sends a warning signal, so that the staff can conduct timely investigation after seeing the warning signal, and urge the athletes who do not wear and use anti-drowning collars to wear anti-drowning collars, and then continuously detects whether drowning signals are received from the anti-drowning collars being worn and used, so as to prevent drowning accidents.

[0025] The present invention is further described in detail below in conjunction with specific implementation methods.

[0026] The present embodiment provides a remote anti-drowning management system based on anti-drowning collars, which includes a background management terminal and multiple anti-drowning collars. The background management terminal establishes a remote communication connection with the multiple anti-drowning collars.

[0027] In this embodiment, the anti-drowning collar is as follows Figure 2 and Figure 3 As shown, it includes a collar body 1, through which the athlete wears the anti-drowning collar around the neck, and a power switch 2, an air pressure sensor 3 and an inflation button 5 are arranged on the periphery of the collar body 1, wherein the power switch 2 is arranged at the rear side of the collar body 1, and the air pressure sensor 3 and the inflation button 5 are arranged at the front side of the collar body 1.

[0028] The collar body 1 is built with a compressed airbag, an air pump, an acceleration sensor, a controller and a remote communication module. The air outlet of the air pump is connected to the compressed airbag, which surrounds the collar body 1. The collar body 1 is provided with a closed seam 4 at the position corresponding to the compressed airbag, which can be opened by the inflated compressed airbag. The acceleration sensor is specifically a gyroscope, which measures the acceleration sensing data of the anti-drowning collar's deflection, tilt and other actions and sends it to the background management end. The power switch 2, the air pressure sensor 3, the inflation button 5, the air pump, the acceleration sensor and the remote communication module are electrically connected to the controller respectively. The controller is specifically an MCU controller, which can receive a start signal and a shutdown signal from the power switch 2, can control the start of the air pressure sensor and receive the pressure data detected by the air pressure sensor, can control the start of the acceleration sensor and receive the acceleration sensing data detected by the acceleration sensor, can receive the inflation signal from the inflation button 5, can establish a remote communication connection with the background management end through the wireless communication module, send the pressure data and the acceleration sensing data to the background management end, and can generate a drowning signal to send to the background management end, and control the air pump to start and inflate the compressed air bag according to the drowning signal. After the compressed air bag is inflated, it expands and opens the closing seam 4 to expose it outside the collar body 1.

[0029] The backend management terminal includes a memory and a processor connected to each other, wherein a computer program product is stored in the memory, and the computer program product includes a computer program, and when the computer program is executed by the processor, the following is realized: Figure 1 The remote drowning prevention management method based on the drowning prevention collar shown includes the following steps S1, S2, S3, S4, S5, S6, and S7.

[0030] S1. Obtain the number of athletes who are to perform water sports input by the user.

[0031] The remote drowning prevention method provided in this embodiment is applied to the background management end of the remote drowning prevention management system. The use scenario of the remote drowning prevention method and system is some specific places where water sports are organized, such as school swimming pools, athlete training pools, etc. These places will uniformly require athletes to wear anti-drowning collars. Before organizing water sports, the user will count the number of athletes to perform water sports, and then enter the number of athletes to perform water sports on the background management end, so that the background management end obtains the number of athletes to perform water sports input by the user.

[0032] S2. Receive the start signal of the anti-drowning collar with which the remote communication connection has been established, and record the number of start signals received.

[0033] When preparing to do water sports, the athlete wears the anti-drowning collar, then presses the power switch 2 on the periphery of the collar body 1 to send a start signal to the controller. After receiving the start signal, the controller controls the air pressure sensor 3 to start acquiring pressure data in real time, and controls the acceleration sensor to start acquiring acceleration sensing data in real time, and then sends the acquired pressure data and acceleration sensing data to the background management end through the wireless communication module. In this way, after obtaining the number of athletes to be engaged in water sports input by the user, the background management end can receive the start signal of the anti-drowning collar with which the remote communication connection has been established, and record the number of start signals received, which means the number of start signals of the anti-drowning collar.

[0034] S3. For the activated anti-drowning collar, receive the pressure data and acceleration sensor data acquired within a preset time period after activation.

[0035] The backend management end receives the pressure data and acceleration sensor data of the activated anti-drowning collar while receiving its activation signal, until receiving the pressure data and acceleration sensor data obtained by the activated anti-drowning collar within a preset time period after activation, such as the pressure data and acceleration sensor data within 10 seconds after activation, and subsequently uses these pressure data and acceleration sensor data to determine whether the corresponding anti-drowning collar is worn.

[0036] S4. Identify the number of anti-drowning collars being worn based on changes in pressure data and acceleration sensor data over time within a preset time period.

[0037] After receiving the pressure data and acceleration sensor data obtained by the activated anti-drowning collar within the preset time period after activation, the backend management terminal identifies the number of anti-drowning collars being worn and used according to the change of these pressure data and acceleration sensor data over time within the preset time period. Specifically, if the anti-drowning collar is being worn and used after activation, the pressure data obtained by its air pressure sensor 3 and the acceleration sensor data obtained by the acceleration sensor will change continuously due to the movement of the person. Therefore, if the pressure data and acceleration sensor data corresponding to a certain anti-drowning collar change continuously over time within the preset time period, the backend management terminal identifies that the anti-drowning collar is being worn and used. If the pressure data or acceleration sensor data corresponding to a certain anti-drowning collar does not change continuously over time within the preset time period, the backend management terminal identifies that the anti-drowning collar is not being worn and used. After identifying the anti-drowning collar being worn and used, the number of anti-drowning collars being worn and used can be counted.

[0038] S5. Compare the number of athletes with the number of anti-drowning collars being worn, and determine whether there are athletes who do not wear anti-drowning collars based on the comparison results. If so, execute steps S6 and S7; if not, do not execute step S6 but only execute step S7.

[0039] After obtaining the number of athletes to perform water sports input by the user and identifying the number of anti-drowning collars being worn, the backend management end compares the number of athletes with the number of anti-drowning collars being worn, and determines whether there are athletes who do not wear anti-drowning collars according to the comparison result. Specifically: if the number of athletes is greater than the number of anti-drowning collars being worn, it is determined that there are athletes who do not wear anti-drowning collars, and step S6 is executed to prompt the athletes who do not wear anti-drowning collars to wear anti-drowning collars, and then step S7 is executed to continuously detect whether drowning signals are received from anti-drowning collars being worn to prevent drowning accidents; if the number of athletes is equal to the number of anti-drowning collars being worn, it is determined that there are no athletes who do not wear anti-drowning collars, and step S6 is not executed, and only step S7 is executed to continuously detect whether drowning signals are received from anti-drowning collars being worn to prevent drowning accidents.

[0040] It should be noted that if the number of athletes is less than the number of anti-drowning collars being worn, it means that the number of athletes entered by the user is inaccurate or that some athletes are using more than two anti-drowning collars. Therefore, the background management end sends a prompt signal so that the user can check the specific situation in time after seeing the prompt signal.

[0041] S6. Issue a warning signal.

[0042] When it is determined that there are athletes who are not wearing anti-drowning collars, the background management end sends a warning signal to the user, for example, by popping up a warning window, issuing a warning voice, etc., so that the user can conduct a timely investigation after seeing the warning signal, and urge the athletes who are not wearing anti-drowning collars to wear anti-drowning collars.

[0043] S7. Continue to detect whether a drowning signal is received from the anti-drowning collar being worn.

[0044] It should be noted that when the sports personnel wear the anti-drowning collar to perform water sports, if drowning occurs, the inflation button 5 of the anti-drowning collar can be directly pressed to inflate and save themselves. Therefore, the controller determines whether the inflation signal from the inflation button 5 is received after startup. If the inflation signal is received, it means that the sports personnel have drowned and pressed the inflation button 5, so the air pump of the anti-drowning collar is controlled to inflate the compressed air bag, so that the air bag expands and opens the closed seam 4 to be exposed outside the collar body 1, and the head of the sports personnel floats to the surface of the water to avoid drowning accidents. At the same time, the controller generates a drowning signal and sends it to the background management end through the wireless communication module, so that the user can monitor whether someone is drowning through the background management end. Therefore, no matter whether there is a sports personnel who does not wear the anti-drowning collar, the background management end will continue to detect whether the drowning signal from the anti-drowning collar being worn is received, if it is received, it means that someone is drowning, and it is necessary to assist in rescue to prevent drowning accidents.

[0045] The above is only an implementation method of the invention, and does not limit the scope of patent protection. Those skilled in the art can make non-substantial changes or substitutions based on the invention, which still fall within the scope of patent protection.
