Fig. 1 is a schematic diagram of an anti-drowning device according to an embodiment of the invention. The anti-drowning device includes at least one anti-drowning device 10, a plurality of repeaters 20, a host 30, and at least one life-saving alarm device 40. In this embodiment, Most of the repeaters 20 are four repeaters 21, 22, 23, 24 respectively arranged at the four corners of the swimming pool 90. The anti-drowning device 10 is worn on the swimmer. The figure shows the swimming pool 90 as an example. There are five anti-drowning devices 11, 12, 13, 14, 15 worn by five swimmers respectively. At least one lifesaving alarm device 40 is shown as a bracelet worn by a lifeguard. The host 30 includes A computer device 31, a receiving device 33, and a transmitting device 34. The aforementioned anti-drowning device in this creation is configured in a swimming pool 90, but this creation is not limited to this. The anti-drowning device in this creation can also be configured in an open water area, such as a stream, or any water splashing facility.

FIG. 2 is a schematic diagram of an anti-drowning device according to an embodiment of the invention. As shown in the figure, the anti-drowning device 10 has an identification code (ID), and the anti-drowning device is a one-piece housing 19 sealed and electrically connected It is composed of a battery 11, a Hall switch 12 and a transmitting device 13. When in use, the Hall switch 12 is turned on with a magnetic substance, and the identification code of the anti-drowning device 10 and the corresponding swimmer data are recorded in the computer device 31. At this time, the battery 11 supplies power to the transmitting device 13 so that the transmitting device 13 transmits the first signal S1 with the identification code, wherein the first transmitting device 13 transmits the signal every first time T1.

3 is a schematic diagram of a repeater according to an embodiment of the creation. As shown in the figure, the repeater 20 includes a receiving device 22 and a transmitting device 21, wherein the receiving device 22 receives the first signal S1, and the transmitting device The device 21 transmits a second signal S2 corresponding to the first signal S1. It should be noted that, referring to FIG. 2 together, the signal transmission and reception between the transmitting device 13 and the receiving device 22 is wireless transmission, and the second transmitting device 21 transmits a signal every second time T2. The first time T1 is greater than the second time T2. Preferably, the first time T1 is hundreds to thousands of times the second time T2. In this embodiment, the first time T1 is 1024 times the second time T2.

In addition, when the anti-drowning device 10 is located underwater exceeding a predetermined depth (for example, 30 cm), the first signal S1 sent by the transmitting device 13 will not be received by the receiving device 22 because it cannot pass through this water depth.

Please also refer to FIG. 1 again, most repeaters 20 are connected to the host 30 by signal lines, so that the receiving device 33 receives the second signal S2, that is, the signal transmission and reception between the transmitting device 21 and the receiving device 33 is a wired transmission , And according to the second signal S2, the computer device 31 can obtain the identification code therefrom. And as mentioned above, if the computer device 31 of the host 30 fails to obtain a specific identification code from the received second signal S2 after a predetermined time has elapsed, it can be determined that the specific drowning prevention device 10 is disconnected.

As shown in Figure 1, each repeater 20 of the anti-drowning device of the present creation has a signal receiving range for the anti-drowning device 10, such as the circle and dotted line in the figure. Therefore, the four repeaters 21 in the figure The four signal receiving ranges of, 22, 23, 24 can roughly divide the swimming pool 90 into four management areas 91, 92, 93, 94, that is, the signal receiving range of each repeater 20 for the anti-drowning device 10 Defined as a management area.

When the anti-drowning device of this creation is in use, each swimmer receives an anti-drowning device 10, and records the identification code of the anti-drowning device 10 and the corresponding swimmer data in the computer device 31. The swimmer can put a sheet of anti-drowning device The device 10 is placed in a swimming cap, but the anti-drowning device 10 of this creation is not limited to a sheet-shaped body. For example, the anti-drowning device 10 can be made into a clip body to be clamped on the swimmer’s swimming goggles. , The drowning prevention device 10 can be made into various forms suitable for being worn on swimmers. At this time, the anti-drowning device 10 continuously wirelessly transmits the first signal S1, and the repeater 20 corresponding to the management area where the swimmer is located receives the first signal S1, and sends the second signal S2 to the second signal S2 through the wired signal connection. The host 30, the host 30 can obtain an identification code from the received second signal S2, and determine the management area where the drowning prevention device 10 is located according to which repeater 20 the obtained identification code is sent from, In this embodiment, the host 30 determines the management area of the closest signal receiving range where the drowning prevention device 10 is located, but this creation is not limited to this. Because the signal receiving ranges overlap, the host 30 can also be designed The received second signal S2 is used to further determine which overlap of the management area the drowning prevention device 10 is.

According to the example shown in Figure 1, at a moment, the drowning prevention device 11 is located in the management area 91, the drowning prevention device 12 is located in the management area 92, the drowning prevention devices 13, 14 are located in the management area 93, and the drowning prevention device 15 is located in the management area 94. Take the signal transmission and reception in the management area 91 as an example. As shown in Figure 4, at a time of T1 (=1 second), the drowning prevention device 11 sends out a signal S1, which can be used by a repeater 21 and 22, and because the anti-drowning device 11 is closer to the repeater 21, the repeater 21 will receive the signal S1 before the repeater 22. Furthermore, the repeater 21 will receive the signal S1 at a T2 time (= 1/1024 second) sends the signal S2-1 corresponding to the signal S1 to the host 30, and the repeater 22 sends the signal S2-2 corresponding to the signal S1 to the host 30 at a time of T2 (=1/1024 second). The device 21 receives the signal S1 earlier than the repeater 22, so the host 30 will also receive the signal S2-1 and discard the signal S2-2 before it is transmitted. According to the signal S2-1, the signal S2-1 is obtained. Identification code, at the same time, it is determined that the 11-bit anti-drowning device is in the management area 91. Of course, the host 30 may not discard the signal S2-2, but based on the signals S2-1 and S2-2 to determine that the 11-bit anti-drowning device is in the management area 91 faces in the overlapping area of the repeater 21.

If the swimmer wearing the anti-drowning device 11 drowns, the first signal S1 sent by the transmitting device 13 of the anti-drowning device 11 cannot pass through the depth of the drowning. Therefore, the host 30 fails to pass a predetermined time (for example, 20 seconds). When the identification code of the anti-drowning device 11 can be derived from the received second signal S2, it is determined that the anti-drowning device 11 is disconnected, and the host 30 determines the identification code of the anti-drowning device 11 based on the disconnection before A repeater sends out and determines the management area where the anti-drowning device 11 is drowning. In this example, since the identification code of the anti-drowning device 11 obtained before the disconnection is issued by the repeater 21, the anti-drowning device is determined 11 Drowning occurred in the management area 91.

Furthermore, when it is determined that drowning occurs, the transmitter device 34 of the host 20 will wirelessly send an alarm to the life-saving alarm device 40 worn on the lifeguard. The alarm system includes the disconnected anti-drowning device 11 and the corresponding swimmer. The information and the management area 91 where the drowning occurred are displayed on the life-saving alarm device 40 and a warning sound and light are issued to notify the lifeguard and let the lifeguard know the location of the drowning and the characteristics of the swimmer, and can make immediate and effective Rescue.
