Description

Position tracking life jacket minimizing battery power consumption}

The present invention relates to a life jacket (life jacket) that prevents the wearer from drowning during distress on the water, and more specifically, to enable rapid rescue by automatically transmitting a wireless signal upon receipt, but the power of the battery is consumed before obtaining It relates to a life jacket for location tracking that minimizes the power consumption of the battery, which prevents accidents in which the function is not implemented due to insufficient power of the battery.

Life jackets (life jackets) are worn by a person in an emergency on the water, and are used for the purpose of allowing them to rise above the water without drowning.

The general life jacket simply plays a passive role in preventing the wearer from sinking in the water, but does not actively help the user in an emergency situation to be rescued early.

Since it is very difficult to find a victim drifting while wearing a life jacket in the open sea during a water distress, technologies in which various functions are grafted into a life jacket are being introduced so that the victims in an emergency situation can be easily rescued.

For example, conventional techniques such as “life vests having a location tracking function” and “rescue vests for emergency rescue with location tracking” have been applied to the life jackets to The life jacket is equipped with a function of tracking a location or transmitting a rescue signal in distress through wireless communication.

Due to the limitation of battery capacity, most life jackets are operated by the wearer to track location and transmit distress signals.

However, it is difficult to expect a victim who is embarrassed by a water distress to check whether the life jacket has the function of tracking the location and transmitting the distress signal, and to allow it to be implemented.

Therefore, it is desirable that location tracking and the transmission of distress signals are automatically performed in distress.

In order for location tracking and transmission of distress signals to be performed automatically during distress, the sensor must detect distress and the controller must be able to operate by receiving the signal from the sensor.

The power consumed by the sensor operating to detect distress is less than the power consumption of GPS for location tracking and the power consumption of the communication module that transmits the distress signal, and the controller is inactive before receiving the signal from the sensor. It can consume, but the power consumption cannot be ignored because the sensor and the controller are always operating, so you have to check the condition of the battery installed in the life jacket and replace or charge it from time to time.

The present invention was conceived to solve the problem of shortening the life of the battery due to the constant operation of the distress detection sensor in the life jacket that automatically transmits the location tracking and distress signal during a water distress. When a life jacket is obtained, the sensor Provides a life jacket for location tracking that minimizes the power consumption of the battery, which prevents accidents that fail to perform the functions of location tracking and rescue signal transmission during distress due to insufficient battery capacity by operating the controller and the like. It is aimed at.

As shown in the drawing, the life jacket according to the present invention includes a main body 10, an ingestion sensor 20, a battery BT1, a power supply module 30, an inflatable body 40, an expansion sensor 50, and a structure A signal generator 60, GPS 70, communication module 80, controller 90, etc. are included.

The main body 10 includes an inner skin and an outer skin, and a buoyancy member that is embedded between the inner and outer skin to provide buoyancy.

The buoyant member of the body 10 interferes with the activity of the wearer of the body 10.

Therefore, the present invention reduces the amount of buoyancy members built into the body 10 in order to increase the activity of the wearer of the body 10 before obtaining, and the inflatable body 40 that provides buoyancy by being expanded by automatically or manually operating during distress. Is provided in the main body 10.

The inflatable body 40 may be composed of a tube and a gas injected into the tube. Here, the gas may be manually blown by the wearer and injected into the tube, and the compressed gas (eg, CO2) may be discharged and injected into the tube by manually or automatically operating the gas.

The inflatable body 40 may be composed of a material that is foamed by a chemical reaction. For example, the inflatable body 40 is made of components such as a foaming resin, a foaming accelerator, and a material for accelerating reaction (e.g., CO2, H2O), and upon receipt, these components are manually or automatically mixed and chemically reacted to foam ( Can expand).

The inflatable body 40 is embedded in the packaging pack 41, the packaging pack 41 has an opening 42 formed therein for interior and replacement of the inflatable body 40, and the opening 42 is an opening and closing member 43 , 44).

In order to monitor whether the inflatable body 40 is inflated, the opening and closing members 43 and 44 are provided with an expansion sensor 50. When the opening/closing members 43 and 44 are opened due to the expansion of the inflatable body 40, the expansion detection sensor 50 detects this and transmits it to the controller 90.

The ingestion detection sensor 20 detects the ingestion of the body 10, that is, the water distress of the victim,

The power supply module 30 allows the power of the battery to be output when the ingestion detection sensor 20 detects ingestion, so that the controller 90, the communication module 80, the GPS 70, etc. are activated and operated. do.

Referring to FIG. 2, the power supply module 30 is composed of a first transistor (Q1), a second transistor (Q2), ingestion detection sensors (J1, J2) and peripheral devices thereof.

The first transistor Q1 is connected to the output line of the battery BT1 and causes the power of the battery BT1 to be output or cut off the output through a turn-on/turn-off operation. That is, when the first transistor Q1 is turned on, the power of the battery BT1 is output and supplied to the controller 90, the communication module 80, and the GPS 70, and when the first transistor Q1 is turned off, the battery (BT1) power is not output.

The acquisition detection sensors J1 and J2 are connected to the output line of the battery BT1 and the base terminal side of the second transistor Q2.

The water intake sensor (J1, J2) has a very large resistance value that can be seen indefinitely so that the power of the battery BT1 is not output, and when water is in contact with the inlet, it has a resistance value of about 50K ohms, and the battery ( BT1) power is output.

Upon receipt, the resistance values of the receipt detection sensors J1 and J2 are lowered, so that the output power of the battery BT1 is applied to the first transistor Q1 and the second transistor Q2. Power of the battery BT1 is directly applied to the first transistor Q1 connected to the output line, and the second transistor is applied through the resistor R2.

In addition, when the resistance value of the access sensor (J1, J2) is lowered by access, the power of the battery BT1 is applied to the capacitor C1 and the resistance R3 at the base terminal side of the second transistor Q2. A voltage is applied to the base terminal of the second transistor Q2, which is an NPN transistor, so that the second transistor Q2 is turned on.

When the second transistor Q2 is turned on, the voltage of the gate terminal of the first transistor Q1, which is a FET connected thereto, becomes LOW, so that the first transistor Q1 is turned on, and then the power of the battery is turned on. The driving power supply VIN is supplied to the controller 90 through the transistor Q1.

The controller 90 receiving the driving power of the battery BT1 is activated to supply power to the communication module 80, GPS 70, etc., and also supply the voltage POWER1 to the base terminal of the second transistor Q2. Thus, the turn-on state of the second transistor Q2 is maintained. In other words, even if the function of the ingestion detection sensors J1 and J2 is released (ie, the resistance value becomes infinite), the turn-on state of the second transistor Q2 is maintained.

The expansion sensor 50 detects the opening and closing of the opening 42 of the packaging pack 41 containing the inflatable body 40.

The packaging pack 41 is provided with an opening and closing member for opening and closing the opening 42. As the opening and closing member, male and female Velcro tapes 43 and 44 or snap buttons 45 and 46 may be used.

And if the male and female Velcro tapes 43 and 44 use a conductive Velcro tape containing conductive yarn, as shown in the circle of Fig. 3A, the expansion sensor 50 is attached to the opening and closing members 43 and 44. Conductive yarn is contained, and the female (or male) velcro tape 43 is separated into two to act as a pair of connection terminals 51A, 52A, and the male (or female) velcro tape 44 is connected to the line It can also be made to act as (53A).

3B, the expansion sensor 50 includes a pair of female snap buttons 45 connected to the controller 90, a male snap button 46 fastened to the female step button 45, A pair of female snap buttons 45 and a pair of male snap buttons 46 may be composed of a connection line 55 electrically connecting them. Here, the connection line 55 may be a conductive yarn.

Male and female Velcro tapes 43 and 44 for opening and closing the opening 42 of the packaging pack 41 or male and female snap buttons 45 and 46 are attached (fastened) to each other, that is, the packaging pack 41 When the opening is closed, the expansion sensor 50 is shorted and a low voltage is applied, and the male and female Velcro tapes 43 and 44 or the male and female snap buttons 45 and 46 are separated from each other, that is, the packaging pack 41 When the opening of) is open, the expansion sensor 50 is open and a high voltage is applied.

The compressed gas cylinder 40 is mounted inside the main body 10 (possibly externally) and discharges gas into the main body 10, and the main body 10 functions as a packing pack 41. can do. The body 10 has a folded portion (indicated by a dotted line in Figs. 4A and 4B). When carbon dioxide is discharged from the compressed gas cylinder 40 and the body 10 is expanded, the folded portion is unfolded, and the folded portion of the body 10 can be said to serve as the opening 42 of the packaging pack 41.

As shown in FIGS. 4A and 4B, male and female Velcro tapes 43, 44 and snap buttons 45, 46 are provided on both sides of the folded portion of the main body 10, so that the folded portion of the main body 10 They are unfolded and separated from each other, and when these 43 and 44 or 45 and 46 are separated from each other, the expansion sensor 50 detects this and transmits it to the controller 90.

The rescue signal generator generates a rescue signal (e.g., SOS signal) in distress, the GPS 70 receives a signal from an artificial satellite to obtain location information, and the communication module 80 transmits rescue signals and location information to the surroundings. Spread.

When the power of the battery BT1 is supplied through the power supply module 30, the controller 90 is activated to start the operation.

The activated controller 90 applies power to the base terminal of the second transistor Q2 to maintain the turned-on state, and determines whether the inflatable body 40 is expanded from the voltage applied to the expansion sensor 50.

When it is determined from the expansion sensor 50 that the inflatable body 40 is inflated, the controller 90 supplies power to the GPS 70 to receive location information because the life jacket wearer is in distress. Then, power is supplied to the rescue signal generator to generate rescue signals, and power is supplied to the communication module 80 to wirelessly transmit location information and rescue signals.

When the controller 90 determines that the inflatable body 40 is not inflated by the expansion sensor 50, the inflatable body 40 is not operated or the victim operates the inflatable body 40 even in a distress state. Assuming that it is not inflated, an alarm sound or a guide sound is output to inform the wearer that the inflatable body 40 is to be operated, and if the inflatable body 40 is not inflated for a certain time after that, it is not obtained due to distress. It is determined that the base terminal of the second transistor Q2 is made low to turn off the second transistor Q2, and accordingly, the first transistor Q1 is turned off, thereby stopping the power output of the battery BT1.
