Description

Technical Field

[0001] The utility model relates to the technical field of falling into water detection, in particular to an intelligent life jacket. Background Art

[0002] Current smart life jackets mostly come in the following forms: They integrate communication and positioning technologies, transmitting a person's current location information to rescuers via 4G / 5G, AIS communication, or Beidou short message communication. Regardless of the type of smart life jacket, one of its core functions is to automatically trigger an alarm when a person falls into the water. Conventional smart life jackets with water-fall alarms use a single contact-type water immersion sensor consisting of two metal contacts. This sensor uses the conductivity of water to detect water immersion and trigger an alarm based on the contact between the metal and the liquid. However, in actual use, it is impossible to determine whether a person has actually fallen into the water. A small amount of water accumulation between the two electrodes will cause the water-fall device to sound an alarm. This is especially true for life jackets, which are often used on water and inevitably come into partial contact with water. If the water-contacted area happens to be located at the sensor location on the life jacket, it is easy to mistakenly determine that the person is currently in the water and trigger an alarm.

[0037] See Figure 2 and Figure 3 The present invention also provides an intelligent life jacket, including a life jacket body, on which a controller U1 and a plurality of water-falling triggering electrode sheets are provided. The plurality of water-falling triggering electrode sheets are electrically connected to the controller U1 respectively, and the plurality of water-falling triggering electrode sheets are respectively distributed at the upper two ends of the front side of the life jacket body, the lower two ends of the front side of the life jacket body, the upper two ends of the back side of the life jacket body, and the lower two ends of the back side of the life jacket body.

[0038] From the above description, it can be seen that the beneficial effects of the present invention are:

[0039] The utility model provides an intelligent life jacket, in which the above-mentioned water-falling triggering electrodes are distributed at various positions of the life jacket body, including the upper two ends of the front side of the life jacket body, the lower two ends of the front side of the life jacket body, the upper two ends of the back side of the life jacket body, and the lower two ends of the back side of the life jacket body. Therefore, the water immersion status of different areas of the life jacket can be accurately located through trigger signals at different positions, and this status can be identified and processed, thereby solving the problem that "when the life jacket is partially in contact with water and the water-contacted area happens to be located at the sensor position of the life jacket, it is easy to mistakenly judge that the current person is in the water state and activate the alarm."

[0040] Furthermore, the life jacket body is also provided with a water-falling alarm device, the output end of the controller U1 is electrically connected to the serial signal input end of the water-falling alarm device, and the output ends of the plurality of water-falling trigger electrode sheets are respectively electrically connected to the switch signal input end of the water-falling alarm device.

[0044] From the above description, it can be seen that the water-fall alarm function is realized through the above circuit design.

[0045] Please refer to Figure 1 , the first embodiment of the present utility model is:

[0046] A water-triggering electrode sheet 10 for a smart life jacket comprises a first insulating substrate 3, a first electrode 1, a second electrode 2, and a second insulating substrate 4. The first and second electrodes 1 and 2 are both sheet-shaped and spaced apart on the first insulating substrate 3. Each of the first and second electrodes 1 and 2 is 0.2 cm thick, forming a thin sheet. This sheet is flexible, adaptable to various surfaces, and exhibits excellent electrical conductivity, making it ideal for flexible devices such as smart life jackets. Both the first and second insulating substrates 3 and 4 are made of plastic.

[0047] The second insulating substrate 4 is covered on the first electrode 1 and the second electrode 2 and together with the first insulating substrate 3 covers the first electrode and the second electrode. The distance between the exposed portion of the first electrode 1 and the exposed portion of the second electrode 2 is not less than 1 cm so that the first electrode and the second electrode are not conductive in a water mist environment.

[0048] This embodiment uses the resistance and conduction state between two electrodes as a trigger signal, leveraging the conductivity of water. When water is present between the two electrodes, it is equivalent to a conduction state. Specifically, thin-film conductive materials are used as electrode sheets. These materials are flexible, adaptable to various surface shapes, and exhibit excellent conductivity, making them ideal for flexible devices such as life jackets. Figure 1 In the figure, electrodes A and B are made of conductive materials. The two electrodes are extended to the connecting line, which is attached to the bottom plastic substrate. In the extension line area, the extension lines of electrodes A and B are covered with plastic substrate to ensure that the distance between the exposed areas of electrodes A and B is 1 cm, ensuring that there is no connection between electrodes A and B in a water mist environment.

[0049] Please refer to Figures 2 to 5 , the second embodiment of the present utility model is:

[0050] The present utility model also provides an intelligent life jacket, including a life jacket body, on which a controller U1 and a plurality of water-falling triggering electrode sheets are provided. The water-falling triggering electrode sheets are the water-falling triggering electrode sheets in Example 1. The plurality of water-falling triggering electrode sheets are electrically connected to the controller U1 respectively, and the plurality of water-falling triggering electrode sheets are respectively distributed at the upper two ends of the front side of the life jacket body, the lower two ends of the front side of the life jacket body, the upper two ends of the back side of the life jacket body, and the lower two ends of the back side of the life jacket body.

[0051] The life jacket body is also equipped with a water fall alarm device. The output of the controller U1 is electrically connected to the serial signal input of the water fall alarm device, and the outputs of the plurality of water fall triggering electrode sheets are electrically connected to the switch signal input of the water fall alarm device. In this way, data exchange with the water fall alarm device is achieved.

[0052] Specifically, the water-fall alarm device includes an adjustment resistor R1, a transistor Q1, a controller U2, a pull-down resistor R2, and a power switch Q2. The output of the controller U1 is electrically connected to the input of the controller U2. The outputs of the multiple water-fall triggering electrode sheets are respectively electrically connected to one end of the adjustment resistor R1 and the gate of the transistor Q1. The other end of the adjustment resistor R1 and the drain of the transistor Q1 are respectively electrically connected to the power supply VBAT. The power supply VBAT is electrically connected to the power input of the power switch Q2. The source of the transistor Q1 is respectively electrically connected to one end of the pull-down resistor R2 and the switch signal input of the power switch Q2. The other end of the pull-down resistor R2 is grounded. Through the above circuit design, the water-fall alarm function is realized.

[0053] The electrode sheets of this embodiment are distributed in the following manner: Figure 2 and Figure 3 As shown, eight electrodes are distributed on the life jacket, with two on the upper and lower back, and two on the upper and lower front. Each electrode is secured to the life jacket by sewing the edge of the plastic substrate. Wires extending from the electrodes connect to a water immersion detection device, which is attached to the life jacket. After the eight electrode extensions are connected to the water immersion detection device, the device's internal circuitry converts the eight water immersion detection signals into switch signals and serial signals, which are then sent to the water fall alarm. When electrodes 1 and 2 are both conducting, it indicates that the person's back is submerged in water, and they are tilted face-up. When electrodes 1 and 3, 5 and 7, 2 and 4, 6 and 8 are all conducting, it indicates that the person is sideways. Similarly, the water immersion status of different areas of the life jacket can be accurately determined by the different electrode immersion states.

[0054] like Figure 4As shown, eight electrodes are connected to the water detection device via connecting cables. U1 is a shift register, which converts the switching signals from electrodes 1 to 8 into a single serial signal that is sent to the waterlogging alarm device. Diodes D1 to D8 are diodes that prevent the switching signals from the electrodes from interfering with each other. When one or more of electrodes 1 to 8 come into contact with water and become conductive, the waterlogging detection switch signal is pulled low, and the corresponding input port of U1 is pulled low, outputting the signal as a serial signal. For example, when electrodes 2 and 4 come into contact with water, they are approximately conductive, and the waterlogging detection switch signal is approximately conductive to GND. The waterlogging alarm device recognizes this input state and turns on power. At the same time, the U1 shift register outputs the signal 10101111 in serial from the 0th bit to the 7th bit through the low state of electrode piece 2 and electrode piece 4, where 0 indicates the low state of electrode piece 2 and electrode piece 4, and 1 indicates that the corresponding electrode piece is not turned on. In this way, this serial signal is sent to the water fall alarm device for identification and processing.

[0055] like Figure 5 As shown, in the overboard alarm device, R1 is a resistor for adjusting the water detection sensitivity, Q1 is a transistor, U2 is the overboard alarm controller, R2 is a pull-down resistor, and Q2 is the power switch for the overboard alarm device. When any of electrodes 1 through 8 contacts water, a water detection switch signal is generated. The water detection switch signal in the overboard alarm device enters a low-resistance state. This signal, connected in series with R1, forms a voltage divider for VBAT. This voltage divider controls the conduction of transistor Q1. R2 is a weak pull-down resistor. When Q1 turns on, the power switch signal transitions from a low-level signal before triggering to a high-level signal, turning the power switch on. At the same time, the controller U2 detects the conduction information of the electrode piece 1 to the electrode piece 8 of the water immersion detection serial signal input, and accurately locates the water immersion status of different areas of the life jacket through the conduction status of different electrode pieces, identifies and processes this status, and solves the problem of "the life jacket is partially in contact with water. When the contact water area happens to be located at the sensor position of the life jacket, it is easy to mistakenly judge that the current person is in a state of falling into the water and activate the alarm."

[0056] In summary, the present invention provides a water-triggering electrode sheet for a smart life jacket, which utilizes a first electrode and a second electrode, both in sheet form, spaced apart on a first insulating substrate. The second insulating substrate covers the first and second electrodes and, together with the first insulating substrate, covers the first and second electrodes. The spacing between the exposed portion of the first electrode and the exposed portion of the second electrode is no less than a preset threshold, ensuring that the first and second electrodes are non-conductive in a water mist environment. This allows the water-triggering electrode sheet to have good flexibility, adapt to surfaces of varying shapes, and exhibit good electrical conductivity, making it very suitable for use in flexible devices such as life jackets. At the same time, the spacing between the exposed portion of the first electrode and the exposed portion of the second electrode is no less than a preset threshold, ensuring that the first and second electrodes are non-conductive in a water mist environment, thereby avoiding false triggering. The utility model provides an intelligent life jacket, in which the above-mentioned water-falling triggering electrodes are distributed at various positions of the life jacket body, including the upper two ends of the front side of the life jacket body, the lower two ends of the front side of the life jacket body, the upper two ends of the back side of the life jacket body, and the lower two ends of the back side of the life jacket body. Therefore, the water immersion status of different areas of the life jacket can be accurately located through trigger signals at different positions, and this status can be identified and processed, thereby solving the problem that "when the life jacket is partially in contact with water and the water-contacted area happens to be located at the sensor position of the life jacket, it is easy to mistakenly judge that the current person is in the water state and activate the alarm."
