Description

Technical Field

[0001] The present invention relates to the technical field of early warning devices, and in particular to a method for using a water surface wave detection and early warning device. Background Art

[0002] There is a Chinese utility model patent published on January 30, 2018, with the announcement number CN206946670U, which is a swimming pool alarm. By setting an acceleration sensor, it can detect whether a person or other animal falls into the water.

[0003] However, the swimming pool alarm has certain defects when in use: for example, when people are swimming in the swimming pool, the alarm needs to be taken out of the swimming pool to avoid false alarms during swimming. However, after swimming, people sometimes forget to put the alarm back into the water, which results in the failure to detect and alarm in time when someone or other animals fall into the water, and there are still safety hazards. Summary of the invention

[0004] In order to overcome the shortcomings of the prior art, the present invention provides a method for using a water surface wave detection and warning device to solve the problem that people sometimes forget to put the alarm back into the water after swimming, resulting in failure to detect and alarm in time when people or other animals fall into the water, and there is still a safety hazard.

[0005] In order to solve the above technical problems, the present invention provides the following technical solutions: a method for using a water surface wave detection and early warning device, the detection and early warning device comprising a detector, the detector having an awake state and a dormant state, when the detector is in the awake state, the detector has an alarm mode and a swimming mode, the detector comprising a first MCU, a timing module, an acceleration sensor, an alarm indicator light, a swimming indicator light, a wake-up indicator light and a first alarm module, the first MCU being electrically connected to the timing module, the acceleration sensor, the alarm indicator light, the swimming indicator light, the wake-up indicator light and the first alarm module, the acceleration sensor being used to detect the magnitude of the shaking acceleration of the detector, and the method for using the detector comprising the following steps:

[0006] 1. Wake-up detector: shake the detector quickly several times by hand. When the acceleration sensor detects that the acceleration value is greater than the set first threshold value X times within the first specified time, the wake-up indicator light turns on.

[0007] 2. Adjust the detector to the alarm mode or swimming mode: shake the detector quickly several times by hand. When the acceleration sensor detects that the acceleration value is greater than the set first threshold value Y times within the second specified time, the alarm indicator light or swimming indicator light will light up;

[0008] When the swimming indicator light is on, the alarm indicator light is off, the detector is in swimming mode, the detector is in water, people go swimming, and the acceleration sensor detects that the acceleration value is greater than the set second threshold and less than the set first threshold, the first alarm module does not start the alarm, and the timing module starts the timing;

[0009] When the alarm indicator light is on, the swimming indicator light is off, the detector is in alarm mode, and can perform normal detection and alarm work. The detector is in water. When a person or animal falls into the water, the acceleration sensor detects that the acceleration value is greater than the set second threshold and less than the set first threshold, the first alarm module starts the alarm;

[0010] Among them, when the timing module completes the timing, the alarm indicator light lights up, the swimming indicator light goes out, and the detector switches from the swimming mode to the alarm mode. When the acceleration sensor detects that the acceleration value is greater than the set first threshold value Y times within the second specified time, the alarm mode and swimming mode of the detector can be switched between each other.

[0011] Preferably, the detection and early warning device also includes a receiver, which includes a second MCU, a second alarm module, a power module and a second radio frequency module, the power module is electrically connected to the second MCU, the second MCU is electrically connected to the second alarm module and the second radio frequency module, the detector also includes a first radio frequency module electrically connected to the first MCU, when the first alarm module activates the alarm, the first radio frequency module signal is connected to the second radio frequency module, and the second alarm module activates the alarm.

[0012] Preferably, the first designated time and the second designated time are 4 seconds to 6 seconds, X is 7-10, and Y is 3-5.

[0013] Preferably, the detector comprises a shell, a battery and a circuit board are sealed inside the shell, the battery is electrically connected to the circuit board, and the first MCU, timing module, acceleration sensor and first alarm module are integrated on the circuit board.

[0014] Preferably, a solar panel is provided on the top surface of the housing, and the solar panel is electrically connected to the circuit board.

[0015] Preferably, a vertical rod is fixedly mounted on the bottom surface of the shell, and the interior of the vertical rod is hollow and filled with resin.

[0016] Preferably, the acceleration sensor is a three-axis acceleration sensor unit, and its model is L IS2DW12TR.

[0017] Preferably, the first alarm module and the second alarm module are both buzzers.

[0018] Compared with the prior art, the present invention can achieve the following beneficial effects:

[0019] (1) When people need to swim, they pick up the detector in the swimming pool and shake the detector quickly and manually so that the acceleration of the detector is greater than the set first threshold value for multiple times within the set time. The acceleration sensor senses it and sends a signal to the first MCU. The first MCU controls the swimming indicator light module to start. When the swimming indicator light is on, the program sets that when a person swims, waves are generated so that even if the acceleration sensor of the detector detects that the acceleration is greater than the second threshold value, it will not send a signal to the first MCU, thereby not triggering the first alarm module to alarm. In this way, after shaking the detector to put it in the swimming mode, the detector can be directly placed in the swimming pool, thereby avoiding the existing trouble of people taking the alarm out of the swimming pool after swimming, and preventing people from forgetting to put the alarm back into the water after swimming, which results in the failure to detect and alarm in time when people or other animals fall into the water, and there is still a safety hazard problem.

[0020] (2) Through the timing module, even if people forget to switch the detector from the swimming mode to the alarm mode after swimming, after the timing module is completed, a signal can be sent to the first MCU, and the first MCU controls the alarm indicator light module to start, the alarm indicator light lights up, and the program setting automatically switches to the alarm mode.

[0027] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained in conjunction with specific embodiments below. However, the following embodiments are only preferred embodiments of the present invention, not all of them. Based on the embodiments in the implementation mode, other embodiments obtained by those skilled in the art without making any creative work all belong to the protection scope of the present invention.

[0028] like Figure 1 and Figure 2 As shown, the present invention provides a method for using a water surface wave detection and early warning device, the detection and early warning device includes a detector 1, the detector 1 has an awake state and a dormant state, when the detector 1 is in the awake state, the detector 1 has an alarm mode and a swimming mode, the detector 1 includes a first MCU, a timing module, an acceleration sensor, an alarm indicator light, a swimming indicator light, a wake-up indicator light and a first alarm module (here can be set as a buzzer), the first MCU is electrically connected to the timing module, the acceleration sensor, the alarm indicator light, the swimming indicator light, the wake-up indicator light and the first alarm module, the acceleration sensor is used to detect the shaking acceleration of the detector 1, and the method for using includes the following steps:

[0029] 1: Wake up the detector 1: shake the detector 1 quickly several times. When the acceleration sensor detects that the acceleration value is greater than the set first threshold value X times within the first specified time, the wake-up indicator light is on. Similarly, when the detector 1 is in the wake-up state, shake the detector quickly. The acceleration sensor detects that the acceleration value is greater than the set first threshold value X times within the first specified time. At this time, the wake-up indicator light goes out and the detector 1 switches to the sleep state.

[0030] 2. Adjust the detector 1 to the alarm mode or swimming mode: by holding the detector 1 and shaking it quickly for several times, when the acceleration sensor detects that the acceleration value is greater than the set first threshold value Y times within the second specified time, the alarm indicator light or swimming indicator light will light up;

[0031] When the swimming indicator light is on, the alarm indicator light is off, the detector 1 is in the swimming mode, the detector 1 is in the water, people go swimming, and the acceleration sensor detects that the acceleration value is greater than the set second threshold value and less than the set first threshold value, the first alarm module does not start the alarm, and the timing module starts the timing;

[0032] When the alarm indicator light is on, the swimming indicator light is off, the detector 1 is in the alarm mode, and can perform normal detection and alarm work. The detector 1 is in the water. When a person or animal falls into the water, the acceleration sensor detects that the acceleration value is greater than the set second threshold and less than the set first threshold, the first alarm module starts the alarm;

[0033] When the timing module completes the timing, the alarm indicator light turns on, the swimming indicator light turns off, and the detector 1 switches from the swimming mode to the alarm mode. When the acceleration sensor detects that the acceleration value is greater than the set first threshold value Y times within the second specified time, the alarm mode and the swimming mode of the detector 1 can be switched to each other;

[0034] The first designated time and the second designated time are 4 seconds to 6 seconds, X is 7 to 10, and Y is 3 to 5;

[0035] Here, the first specified time X times is 8 times within 5 seconds, the second specified time Y times is 3 times within 5 seconds, the first threshold is 1.5g (the wind and the waves caused by people and other animals falling into the water will not cause the detector 1 to have such a large acceleration value), the second threshold is 0.2g, and the timing time of the timing module is 1h.

[0036] When people buy the detector 1 and need to use it (the detector 1 is in a dormant state at this time), they hold the detector 1 and shake it quickly, so that the acceleration of the detector 1 exceeds 1.5g 8 times within 5 seconds. The acceleration sensor senses it and sends a signal to the first MCU. The first MCU controls the wake-up indicator to light up, so that the detector 1 is converted from the dormant state to the awake state, and then it is placed in the swimming pool;

[0037] When people need to swim (assuming that the detector 1 is in the alarm mode here), they pick up the detector 1 in the swimming pool, and manually shake the detector 1 quickly so that the acceleration of the detector 1 exceeds 1.5g three times within 5 seconds. The acceleration sensor senses it and sends a signal to the first MCU. The first MCU controls the swimming indicator light to start. When the swimming indicator light is on, it means that the detector 1 switches from the alarm mode to the swimming mode. At this time, the program is set that when a person swims, waves are generated so that even if the acceleration sensor of the detector 1 detects an acceleration greater than 0.2g (but not reaching 1.5g), it will not send a signal to the first MCU, thereby not triggering the first alarm module to alarm. In this way, after shaking the detector 1 to put it in the swimming mode, the detector 1 can be directly put into the swimming pool, thereby avoiding the existing trouble of people taking the alarm out of the swimming pool after swimming, and preventing people from forgetting to put the alarm back into the water after swimming, which results in failure to detect and alarm in time when people or other animals fall into the water, and there is still a safety hazard problem;

[0038] After people finish swimming, they can also pick up the detector 1 in the swimming pool and quickly shake the detector 1 manually to make the acceleration of the detector 1 exceed 1.5g three times within 5 seconds. The acceleration sensor senses it and sends a signal to the first MCU. The first MCU controls the alarm indicator to start. When the alarm indicator lights up, it means that the detector 1 switches from the swimming mode to the alarm mode. At this time, the program is set that when a person or other animal falls into the swimming pool and generates waves so that the acceleration sensor of the detector 1 detects that the acceleration is greater than 0.2g, the acceleration sensor sends a signal to the first MCU, and the first MCU controls the first alarm module to alarm;

[0039] In addition, through the set timing module, even if people forget to switch the detector 1 from the swimming mode to the alarm mode after swimming, a signal can be sent to the first MCU after a certain period of time (here 1 hour after the start of the swimming mode). The first MCU controls the alarm indicator light to start, and the alarm indicator light lights up, and the program setting automatically switches to the alarm mode.

[0040] like Figure 3 As shown, the detection and early warning device also includes a receiver, the receiver includes a second MCU, a second alarm module (which can be set as a buzzer here), a power module and a second radio frequency module, the power module is electrically connected to the second MCU, the second MCU is electrically connected to the second alarm module and the second radio frequency module, the detector 1 also includes a first radio frequency module electrically connected to the first MCU, when the first alarm module starts the alarm, the first radio frequency module signal is connected to the second radio frequency module, and the second alarm module starts the alarm;

[0041] By setting a receiver, the receiver can be placed indoors or carried with you. When the detector 1 is in the alarm mode, when a person or other animal falls into the swimming pool, the waves are splashed, so that the acceleration sensor in the detector 1 detects that the acceleration is greater than 0.2g, and sends a signal to the first MCU. The first MCU controls the first alarm module to alarm, and transmits the signal to the second RF module through the first RF module. The second RF module then sends a signal to the second MCU, and the second MCU controls the second alarm module to alarm, so as to prevent people from not being able to hear the alarm sound of the detector 1 in the swimming pool when they are indoors, and facilitate people to rescue in time;

[0042] In addition, the receiver also includes a button module and a connection light. By setting the button module, the receiver can be matched with the detector 1, so that the first RF module can transmit the signal to the second RF module. When the connection light is on, it indicates that the receiver and the detector 1 are matched successfully.

[0043] like Figure 4 and Figure 5As shown, the detector 1 includes a shell 11, in which a battery 14 and a circuit board 13 are sealed, the battery 14 is electrically connected to the circuit board 13, the first MCU, the timing module, the acceleration sensor and the first alarm module are integrated on the circuit board 13, and the battery 14 is used to supply power to the circuit board 13, thereby supplying power to the first MCU, the timing module, the acceleration sensor, the alarm indicator light, the swimming indicator light, the wake-up indicator light and the first alarm module.

[0044] like Figure 4 and Figure 5 As shown, a solar panel 12 is disposed on the top surface of the housing 11 , and the solar panel 12 is electrically connected to the circuit board 13 . By arranging the solar panel 12 , the battery 14 can be charged (the specific principle is the prior art), thus avoiding the trouble of replacing the battery 14 .

[0045] like Figure 4 As shown, a vertical rod 15 is fixedly installed on the bottom surface of the shell 11. The interior of the vertical rod 15 is hollow and filled with resin. The vertical rod 15 and the shell 11 can be made of plastic material. By setting the vertical rod 15, the overall center of gravity of the detector 1 can be lowered, so that it can float stably on the water surface, and when the water surface fluctuates, the normal movement of the detector 1 can be guaranteed.

[0046] The acceleration sensor here is a three-axis acceleration sensor unit, which is used to detect the acceleration in the three directions of X-axis, Y-axis and Z-axis in water when a person or an animal falls into the water. Its model can be LI S2DW12TR.

[0047] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
