[0030] Next, the disclosed concept of the present invention will be described in detail with reference to the accompanying drawings. What is described here is merely a preferred embodiment of the present invention. Those skilled in the art may conceive of other ways to implement the present invention based on the preferred embodiment, and the other ways also fall within the scope of the present invention. In the following specific description, directional terms such as "upper", "lower", "inner", "outer", "longitudinal", "horizontal", etc. are used with reference to the directions described in the accompanying drawings. The components of the embodiments of the present invention can be placed in a variety of different directions, and the directional terms are for illustrative purposes only and are not restrictive.

[0031] Figure 1 FIG. 1 shows the appearance of a life jacket based on a positioning system according to the present invention, which shows the life jacket from a front angle. Figure 1 As shown, the life jacket consists of a double-layered garment body, a conductive circuit, a power generation system, a positioning system, and an alarm system. The positioning system, conductive circuit, power generation system, and alarm system are attached or fixed to the double-layered garment body. The power generation system utilizes external solar energy to generate electricity and power the positioning system, conductive circuit, and alarm system. The double-layered garment body, serving as the main body of the life jacket, generally has a density lower than that of water. This can be achieved by directly constructing the garment from a material with a lower density than water, or by filling the garment with a large amount of material with a lower density than water.

[0032] The garment body comprises an inner layer that fits the body and an outer layer that is away from the body, and the two layers can be joined together by conventional sewing and / or gluing. A plurality of wires are fixed between the inner and outer layers of the garment body. These wires can be fixed by sewing / gluing threads or fabrics on the inner side of the inner or outer layer of the garment body. The outer layer of the garment body is provided with a plurality of exposed and closable pockets, such as pockets 2, 4, 5, etc. ( Figure 1 4 pockets are shown).

[0033] The surface of the clothing body can be set Figure 1 One or more snap-on elastic bands 3 are shown.

[0034] Conducting circuit such as Figure 2 、 3 As shown, it includes a probe terminal PROBE, a ground terminal GND and at least two conducting sub-circuits ( Figure 24 conducting sub-circuits CN1, CN2, CN3 and CN4 are shown in parallel. The probe terminal PROBE and the ground terminal GND can be electrically connected to each other through any one of the conducting sub-circuits. The above-mentioned conducting sub-circuit includes a first conducting sub-circuit CN1 that is conducted through a water medium and a second conducting sub-circuit CN2 that is manually conducted. The conducting circuit sends a conduction signal through the probe terminal PROBE in the conducting state. The first conducting sub-circuit CN1 has ports that are on the surface of the life jacket and spaced apart from each other. In the absence of water, the two ports of the first conducting sub-circuit are not connected to each other, and the conducting sub-circuit is not connected; when the person falls into the water, the space between the two ports of the first conducting sub-circuit CN1 is filled with (sea) water that can serve as a conductive medium, and the first conducting sub-circuit CN1 is therefore conducted. A switch (such as a push-button switch) for manually controlling the short circuit is set between the two ports of the second conducting sub-circuit CN2. After the person falls into the water, pressing the switch can short-circuit the circuit end of the second conducting sub-circuit CN2 and ground the signal. The switch of the second conducting sub-circuit CN2 can be optionally arranged at Figure 1 One of the multiple pockets shown.

[0035] The power generation system includes a power generation glass 7 fixed to the collar position of the life jacket, a flexible photovoltaic panel 6 covering the outer surface of the front chest, back and shoulder areas of the life jacket, and a power storage device (not directly shown) arranged in at least one pocket, wherein the power generation glass 7 and the flexible photovoltaic panel 6 are electrically connected to the power storage device through independent wires.

[0036] The positioning system includes a positioning track module for locating the coordinate position of the wearer and a transmitter for sending the coordinate position to the outside world. The positioning system can be a positioning system based on the Beidou navigation system or the GPS positioning system. Figure 1 In a preferred embodiment, the positioning system may include a positioning antenna 1. The positioning antenna 1 may be a pop-up antenna 1 that automatically pops out after falling into water.

[0037] The alarm system is electrically connected to the probe end of the conduction circuit and the power storage device through independent wires, and can sound an alarm when receiving a conduction signal.

[0038] As can be understood, the life jacket described above can automatically or manually activate various systems within the life jacket and sound an alarm after a person falls into the water. In particular, because the activation circuit includes at least a first activation sub-circuit CN1 that automatically activates upon a person falling into the water and a second activation sub-circuit CN2 that is manually activated, trouble-free use of the life jacket is ensured. The power generation system is a solar-powered system, providing a stable power supply for the life jacket.

[0039] See also Figure 3, which shows a signal amplification circuit for amplifying the output signal of the probe end. The signal amplification circuit includes a first resistor R1 for current protection, a second resistor R3 for voltage protection, a transistor Q1, a first series resistor R2, a second series resistor R4, an operating indicator LED1, and a pin connector H1 with at least three pin holes. The base of the transistor Q1 is connected to the probe end PROBE via the first resistor R1. The emitter of the transistor Q1 is connected to the power supply VCC, and the collector of the transistor Q1 is connected to the second resistor R3, the second series resistor R4, and the pin connector H1 in parallel. The two terminals of the first series resistor R2 are respectively connected to the power supply VCC and the output terminal of the first resistor R1. The input terminal of the operating indicator LED1 is connected to the output terminal of the second series resistor R4, and the output terminal is connected in parallel with the output terminal of the second resistor R3 and then to ground. The three pin holes of the pin connector H1 include a pin hole for ground GND and a pin hole for connecting to the power supply VCC. The power supply terminal VCC is located on an independent power supply or a power storage device and is manually turned on by the user. The working indicator LED1 is arranged on the outer surface of the life jacket.

[0040] According to the present application, the base conduction current of the Q1 transistor is preferably set to the microampere level, the base conduction voltage of the transistor is preferably set to less than 1 volt, and the voltage at the power supply end is preferably set to less than 8 volts.

[0041] In addition, the voltage of the power supply terminal is preferably set to 5V, the base conduction voltage of the transistor is preferably set to 0.7V, and the resistance values ​​of the second resistor R3 and the first resistor R1 are preferably set to 1KΩ.

[0042] Preferably, the resistance value of the second series resistor R4 is preferably set to 240Ω, and the resistance value of the first series resistor R2 is preferably set to 27KΩ.

[0043] exist Figure 2 The four conductive subcircuits shown include, in addition to the first and second conductive subcircuits CN1 and CN2 described above, a third conductive subcircuit CN3 and a fourth conductive subcircuit CN4. The third conductive subcircuit CN3 is configured to test the operating status of the conductive circuit and alarm system. The fourth conductive subcircuit CN4 is an open port, allowing users to add additional functionality to the CN4 port based on their needs, making the life jacket easier to use.

[0044] Combine Figure 1 、 4 The life jacket may further be provided with an ultrasonic rangefinder for measuring the distance between the wearer and the hull, and the ultrasonic rangefinder is configured to send an alarm signal to the alarm system when the distance exceeds a predetermined distance (which can be set to any value within the range of 100-1000m). Figure 4The signal transmission system shown transmits signals. The ultrasonic rangefinder, composed of RXD2 and TXD2, operates in conjunction with the RXD2. It drives a resonant plate at a frequency of 3000-5000 Hz to transmit ultrasonic waves. A pulse signal is applied to the bipolar transistor at a frequency equal to the oscillation frequency of the chip, driving the resonant plate to vibrate. The echo time method measures the time it takes for the ultrasonic wave to travel back and forth to measure the distance. When the transmitter sends a short pulse, a timer starts; when the receiver receives a return pulse, the timer stops immediately. Ultrasonic signals are transmitted with the drowning person as the radius. Rescue vessels, upon receiving the signal, proceed to the rescue and provide feedback to the rescue management center.

[0045] Optionally, a self-sealing strip and a sliding buckle cooperating with the self-sealing strip are provided at the opening of the pocket for arranging the electricity storage device.

[0046] Preferably, reflective strips are attached to at least the outer surface of the life jacket.
