[0016] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0017] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art in the technical field of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0018] like Figure 1 and Figure 2 As shown, a venue drowning prevention receiving system includes a receiver and a wearable module, and the receiver is divided into an entry receiver 1, a signal receiver 2, an exit receiver 3 and a main controller 4. In addition, in this embodiment, there can be one or more signal receivers 2, such as: if arranged according to the standard swimming pool with a length of 50M and a width of 21M, two signal receivers 2 are required. If a single swimming pool or swimming pool has multiple swimming pools, more signal receivers 2 are required to form an electronic fence for the entire venue, covering the entire venue and being responsible for receiving the entire signal.

[0019] The entry receiver 1 senses the entry signal sent by the wearable module; after entering the venue, the signal receiver 2 receives the on-site signal sent by the wearable module, and sends the on-site signal to the main controller 4. The main controller 4 compares the on-site signal with the set value, and chooses whether to alarm according to the comparison result. The exit receiver 3 receiving module senses the exit signal sent by the wearable module, and signals are transmitted between the entry receiver 1, the signal receiver 2, the exit receiver 3 and the main controller 4.

[0020] In this embodiment, there are multiple signal receivers 2, and the entry receiver 1, signal receiver 2 and exit receiver 3 are arranged in series. Since signals are transmitted and received interactively among the entry receiver 1, signal receiver 2 and exit receiver 3, the entire system will not crash due to a single signal receiver 2 being off.

[0021] The receiver is provided with a mainboard, multiple connection ports, a TYPE-C interface, an RJ45 network cable input port and an RJ45 network cable output port, and the multiple connection ports, the TYPE-C interface, the RJ45 network cable input port and the RJ45 network cable output port are all electrically connected to the mainboard. Figure 3 As shown in the figure, different ports can be connected to different modules, as follows:

[0022] TYPE-C interface: responsible for the power supply of the entire receiver, through the connection of the gallium nitride charger and the TYPE-C interface, 12V voltage is supplied through the PD protocol.

[0023] RJ45 network cable port input: responsible for connecting to the previous signal receiver 2 with a Category 6 network cable, and responsible for data exchange between the previous receiving end and the current base station.

[0024] RJ45 network cable port output: responsible for transmitting the data of the current signal receiver 2 to the next signal receiver 2 via a Category 6 network cable.

[0025] Power button port: Connect a self-locking button with a power indicator light to control the power on and off of the entire receiver.

[0026] Screen port: connected to the screen module 51, and then the interactive information after data processing is transmitted to the screen for display, so as to facilitate interaction with people.

[0027] Alarm port: connect to a module that can make sounds, such as a buzzer or a speaker; used to send a prompt sound on the entry and exit receiver 3 to let the user know that his wearable device has entered or left the venue's drowning prevention receiving system. Also, send a sound alarm when a person is drowning.

[0028] Alarm light port: connected to the indicator light module 53 that can change color, and cooperate with the alarm light to form an audible and visual alarm, so that users and venue staff can understand the current status through vision and hearing.

[0029] Reset button port: A non-self-locking reset button 52 is connected to the port to handle the restart of the receiver and signal restoration in an abnormal state.

[0030] Receiving module port 11: The module connected to channel 1 is responsible for receiving signals from wearable devices entering channel 1.

[0031] Receiving module port 12: The module connected to channel 2 is responsible for receiving signals from wearable devices entering channel 2.

[0032] Receiving module port 13: The module connected to channel 3 is responsible for receiving signals from wearable devices entering channel 3.

[0033] Receiving module port 14: The module connected to channel 4 is responsible for receiving signals from wearable devices entering channel 4.

[0034] In this embodiment, the connection ports are: a power button port, a screen port, an alarm light port, an alarm port, and multiple receiving module ports, and the connection ports are connected to corresponding modules.

[0035] In this embodiment, the screen port is connected to a screen, the alarm light port is connected to an alarm light, and the alarm port is connected to a sound alarm.

[0036] The overall working process of the utility model is described in detail below:

[0037] The receiver can be divided into an entry receiver 1, a signal receiver 2, an exit receiver 3 and a main controller 4, that is to say, the main controller 4 itself contains the function of a receiver, and the receiver, signal receiver 2, exit receiver 3 and main controller 4 are all provided with a receiver mainboard. According to different functions, the modules connected to the receiver, signal receiver 2, exit receiver 3 and main controller 4 are different, such as: the signal receiver 2 is not equipped with a sound alarm module, while the main controller 4 is equipped with a sound alarm module. Similarly, in the actual process, the different functions of the entry receiver 1, signal receiver 2, exit receiver 3 and main controller 4 can be set according to the needs of the site.

[0038] In this embodiment, the multiple connections of the signal receiver 2 are to ensure that an effective electronic fence can be formed in the entire venue to receive signals.

[0039] Among the receivers, only the entry receiver 1, the exit receiver 3 and the main controller 4 have the function of sound alarm. The main controller 4 can independently control the alarm including sound and light alarm, while the sound alarm of the entry receiver 1 and the exit receiver 3 is a prompt tone to remind the user of the entry and exit of the wearable module worn by the user. The signal receiver 2 is not equipped with a sound alarm module.

[0040] The entire system needs to be fully equipped with an entry receiver 1, an exit receiver 3, and a main controller 4 to build an anti-drowning system. The function of the signal receiver 2 is to ensure the signal coverage of the venue's signal electronic fence. N signal receivers 2 can be configured according to the size of the venue, but the entry receiver 1, the exit receiver 3, and the main controller 4 can only be configured with 1 each. The failure of N signal receivers 2 will not affect the overall operation of the system, but will only affect the strength of the electronic fence signal coverage; all receivers use the same receiver mainboard, but the modules and internal algorithm programs are different.

[0041] When the system of the utility model is set up in the swimming place, the personnel put on the wearable module and enter the place:

[0042] 1. Entry: The personnel put on the wearable module, which is usually worn on the head. The wearable module is equivalent to a signal transmitter. The wearable module will send out a corresponding signal. The entry receiver 1 receives the corresponding signal and makes a sound to remind the personnel to enter the venue.

[0043] 2. Inside the venue: After the personnel put on the wearable module and complete the entry, the signal receiver 2 and / or the main control module can receive the signal sent by the wearable module. During the swimming process, since water is a polar molecule, its positive and negative charge centers do not overlap, and thus the direction can change under the action of the electric field in the electromagnetic wave. Once the frequency of the electromagnetic wave is close to the inherent multiple vibration frequencies of the water molecules, the water molecules can absorb most of the energy in the electromagnetic wave and convert it into their own vibrations. The commonly used communication electromagnetic wave frequencies are almost all within the absorption frequency range of water molecules, resulting in very fast attenuation of electromagnetic waves in water. Taking advantage of the fact that wireless communication underwater is very difficult, the signal transmitted by the wearable device is passed through the algorithm inside the signal receiving system of the venue to determine whether the swimmer is drowning.

[0044] In addition, in places such as swimming pools and swimming pools, there is water vapor all year round. Due to the interference characteristics of water, we cannot use traditional rubber stick antennas as the antenna of our signal receiver 2, because the rubber stick antenna has single-line directivity, and the influence of water vapor will inevitably destroy the stability of the system.

[0045] Therefore, in the present invention, an omnidirectional mushroom head is used as a receiving antenna. Generally, when there is no drowning, the signal receiver 2 and / or the main control module can receive the signal sent by the wearable module continuously or at short intervals. If drowning occurs, when the signal receiver 2 and / or the main control module does not receive the signal sent by the wearable module for more than a certain period of time, the main control module controls the module that can sound, such as a buzzer or a speaker, to send a prompt sound on the entry and exit receiver 3 to let the manager know that the person is drowning.

[0046] At the same time, the alarm light port is connected to an indicator light module that can change color, which cooperates with the alarm light to form an audible and visual alarm, allowing users and venue staff to understand the current status through vision and hearing.

[0047] 3. Leaving: The wearable module will send out a corresponding signal, and the exit receiver 3 will receive the corresponding signal. At the same time, after receiving the signal, the exit receiver 3 will record the exit of the wearable module.

[0048] In the present invention, the receiver is divided into an entry receiver 1, a signal receiver 2 and an exit receiver 3. The three receivers are responsible for signal reception at different stages. The entry receiver 1 is responsible for signal reception and processing when the wearable module enters the venue, the signal receiver 2 is responsible for signal reception and processing when the wearable module is in use on the venue, and the exit receiver 3 is responsible for signal reception and processing when the wearable module leaves the venue. The entry receiver 1, the signal receiver 2 and the exit receiver 3 will mutually transmit the received signals, and all the receivers are electrically connected in series, and the entire system will not collapse due to the hanging of a certain signal receiver 2. Therefore, the present invention as a whole has the replaceability of the signal receiver 2, and has high stability, which can largely ensure the safety of swimmers.

[0049] The present utility model is not limited to the above-mentioned optional implementation modes. Anyone can derive other various forms of products under the inspiration of the present utility model. However, no matter what changes are made in the shape or structure, all technical solutions that fall within the scope defined by the claims of the present utility model fall within the protection scope of the present utility model.
