Description

BACKGROUND OF THE INVENTION Field of the Invention [0001] The present invention relates to an apparatus for displaying an accident location of a diving operator using hydraulic pressure and conductivity,

The present invention relates to a method and apparatus for automatically detecting an emergency situation by hydraulic pressure and conductivity when an emergency situation occurs to an underwater worker such as a sea lion or a diver using water pressure and conductivity to cause the buoy to be automatically inflated, To an accident location display device for a diving operator.

This will be explained in more detail. If the sensing value (measured value) is larger than the respective set pressure of water pressure and conductivity, the emergency situation is automatically detected And to provide a device for indicating an accident location of a diving operator using hydraulic pressure and conductivity to automatically inflate the buoy and inform the outside of the risk.

Underwater diving workers (diving women, divers, etc.) carry out work by going back and forth between water surface and water in a certain period of time depending on the type of work. The average time for a general worker to stay in the water is about 15 minutes when wearing an oxygen tank, and about 40 seconds to 2 minutes when an oxygen free worker is working.

Underwater workers working underwater are very difficult to find near by due to the digging when an accident occurs due to the nature of the work environment. Therefore, it is common to escape the accident situation by themselves or to request help from the surrounding area in an aggressive manner.

In case of an accident, there is a method to send a rescue signal to a fellow worker in the water and to indicate the occurrence of an accident on the water surface.

Considering the characteristics that the person's visual and auditory discrimination ability is degraded in the water in case of notifying or reporting an accident in the water, it is very difficult to search the exact point of accident, and therefore it takes a lot of time to search and check the point of accident and accident do.

In order to overcome this situation (it takes much time to search and identify accident and accident points), there is a problem to carry communication equipment for communication between workers, and a method of marking using flags may be considered However, due to the nature of sea and seabed topography, it is not easy to identify and distinguish specific objects.

The relatively simple and inexpensive use of the dive operator in the work area by accident signs on the surface, such as the deployment of the buoy. An indication of an accident may include an accident manifesting itself by an accident manifestation device, or a method of automatically displaying an accident according to a pre-set electronic program procedure.

Whichever way you mark an accident, a common main requirement is to be able to clearly indicate the location of the accidenter.

This is to clearly distinguish whether the accident is underwater or not exposed to water, which is impossible to breathe, and there should be no error (malfunction) in the signal indication, which is one of the main characteristics of the warning signal device.

Frequent errors (malfunctions) signals cause the device to become unreliable, which causes the user to avoid using them. In addition, the mistake of the structure may cause the rescuers to overlook this actual danger situation in actual risk situations. .

As a conventional device for the safety of the submersible (underwater) worker working underwater, there are domestic devices such as the public new utility announcement number room 1985-0000181 (underwater assistance device), the public utility new announcement number room 1989-0005063 (Diving equipment), Japanese Laid-Open Patent Publication No. 10-1998-0841951 (diving equipment), and Japanese Patent Laid-Open No. 10-1353962 (air suctionable teak) Japanese Patent Application Laid-Open No. 2005-263116, Japanese Patent Laid-Open Publication No. 2010-519122, and Japanese Patent Application Laid-Open No. 2001-097280 are known.

As a conventional domestic apparatus, the public utility model number 1985-0000181 (underwater breathing aid apparatus) forms a compartment inside a box floated on water, stores air tubes of rubber in both compartments on the left and right sides, It is equipped with air supply air pump to compress the air into the tube by the pump, and then the air supply conduit attached to the air tube is inserted into the mouth, so that it can work by diving for a comparatively long time while breathing in water. , The air is put into the air tube by a manual air compression pump and then used again. However, since the structure is complicated and the weight is heavy, it can not be easily manufactured (produced) There is a problem that a process of injecting air by an underwater worker can not be easily carried out.

Notice The utility model announcement number 1989-0005063 (the supply device of the diving part) connects the air conduit to the submersible helmet and the diving part which makes the float and the diver float on the sea water, The upper part of the unit is provided with an air supply chamber in which a plurality of diaphragms are overlapped and a water separator for separating air and water so that the sea water does not flow into the air conduit even when the waves are struck, And it is merely an air supply device that allows air to be supplied to the diver.

Open No. 10-1998-0841951 (a diving apparatus) is characterized in that a water permeation preventing cap is assembled to the upper end of a hollow pipe coupled in the middle of the port, a flexible hose is connected to a lower end of the hollow pipe, A mask is connected to the lower end of the diaphragm, and the operator performs the operation while wearing the mask. This is also an air supply device for supplying air to the diver.

Japanese Patent Application Laid-Open No. 10-1353962 (air suctionable teak) is provided with a teak (middle part) in the middle of an air supply pipe so that the upper end of the air supply pipe is exposed to the upper side of the water surface by teak A hose with a mouse is connected to the tip, and the operator performs work while hitting the mouse by asking.

These conventional devices have a problem in that when a safety accident occurs, such a situation can not be notified to the outside.

Japanese Unexamined Patent Application Publication No. 2005-263116 (Bio-information Monitoring Device) monitors the worker's bio-cycle according to the depth of dive and the diving time of an operator working in the deep sea of low temperature, The device will inform you of the dangerous situation.

Japanese Patent Publication No. 2010-519122 discloses a method for detecting a diving state (diving time, etc.) of a wearer in a state wearing (wearing) a life jacket, (Float) as a prime minister.

Japanese Unexamined Patent Application Publication No. 2001-097280 (diver safety observer monitoring device) is provided with a sound informing device for notifying a diver that an abnormality has occurred in a buzzer sound, And a communication device including an ultrasonic transmission / reception unit for acquiring biometric information of a diver using a diving operation monitoring switch such as a body temperature sensor and notifying occurrence of an abnormal state of the diver's body.

These conventional devices are limited in their cognitive functions since they are intended to measure the body function or depth of water of an underwater worker not by hydraulic pressure and conductivity (fresh water or seawater) but to operate a life preserver or a notification device.

The present invention has been made to solve the above-mentioned problems and disadvantages, and to further improve the water pressure and the conductivity by the registered patent application No. 10-1644382 (Emergency situation detection and notification device for underwater workers) And to provide an accident location display device for a submerged worker.

Figs. The hydraulic pressure sensing device 100 and the microcomputer 200 are excerpted from the accident location display device circuit 1-1 of the position display device 1. [

Hereinafter, the structure and operation principle of the diving operator accident location display device 1 using the hydraulic pressure and the conductivity according to the present invention will be described.

1 and 2A and 2B, the dive operator accident position display device 1 using the hydraulic pressure and the conductivity according to the present invention is constructed in such a manner that the water pressure is applied to the surface of the buoy storage bag 400 in which the buoy 500 is housed, The water pressure switch device 10 of the sensing device unit 100 is installed so that the water pressure switch device 10 is exposed to the outside.

The buoy storage bag 400 is generally formed in a rectangular shape (rectangular parallelepiped shape or cuboid shape), and a buoy 500 and various devices (not specifically shown) are formed inside the buoy storage bag 400 A part of the buoy 500 is integrally formed on a part of the inner surface of the buoy storage bag 400 and the buoy storage bag 400 is opened by opening the inlet (not specifically shown) of the buoy storage bag 400, (500) is exposed to the outside of the buoy storage bag (400) and can be fully expanded.

The water pressure sensing device unit 100 installed on the surface of the buoy storage bag 400 is installed such that the water pressure switch device 10 is exposed to the outside of the buoy storage bag 400. The water pressure switch device 10 has a circular shape Or a rectangular shape (shape), but it can be optimized in consideration of the characteristics of the wearer (user).

The buoy 500 installed in the buoy storage bag 400 is formed in the shape of a circle or a rectangle (square or rectangular) as illustrated in FIG. 3C, So that at least 8 kg of buoyancy can be provided.

The dive operator accident location display device 1 using the hydraulic pressure and the conductivity according to the present invention is structured such that the hydraulic pressure sensing device 100, the microcomputer 200, and the gas filling part 200, as illustrated in FIGS. 3A and 3B, (Electrically) formed by a circuit diagram (1-1) of an accident location display device as illustrated in FIG. 4.

The hydraulic pressure sensing device 100 includes the hydraulic pressure switch 10, the conductivity measuring device 30, and the sensor input circuit 110.

5A and 5B, the water pressure switch 10 is installed on one side of the buoy storage bag 500, but the buoy 400 and the buoy storage bag 500 are integrally bonded to each other It is preferable to install it on one surface.

The hydraulic pressure switch device 10 is formed as follows.

5A and 5B illustrate different embodiments in which a bottom surface of a pressure switch case 12 having an open upper portion is fixed (attached) to an outer surface of a buoy storage bag 500. [

5A is a state in which the bottom surface of the pressure switch case 12 is fixed (attached) to the outer surface of the buoy storage bag 500 by an adhesive means such as an adhesive 17.

5B shows an example of another embodiment in which the bottom surface of a pressure switch case 12 having an open upper portion is fixed to the outer surface of the buoy storage bag 500. The bottom surface of the pressure switch case 12 Holes are formed in the center portion and the buoy storage bag 500 and the bolts 20 are inserted into the bolts 20 having the threaded portions formed on the outer surface thereof and the center line of the bolt holes 20-1, And the bolts 20 are inserted into the buoy storage bag 500 and the pressure switch case (not shown) by inserting the nuts 21 in the pressure switch case 12 into the holes in the outside of the buoy storage bag 500, 12 at the center of the bottom surface.

5A and 5B, the bottom surface of the pressure switch case 12 having an open upper portion is fixed to the outer surface of the buoy storage bag 500, The outer surface of the side plate of the pressure switch case 12 and the inner surface of the side plate of the diaphragm 11 are hermetically sealed with the diaphragm 11 formed of rubber or soft synthetic resin, The frame 11 has an annular groove 11-1 at the edge of the upper plate so that the diaphragm 11 can smoothly operate the upper plate.

5A) of the pressure switch case 12 or the upper end (FIG. 5B) of the bolt 20 protruding to the upper side of the nut 21 in the pressure switch case 12 is provided with various electronic parts The circuit board 15 was fixed and a pressure switch 14 was installed at the center of the upper side (upper surface) of the circuit board 15.

The diaphragm 11 integrally fixes the pressure plate 13 having an inverted conical shape on the bottom surface (inner surface) of the upper plate (flat plate) The central pointed portion of the pressure plate 13 turns on / off the pressure switch 14 when the upper plate (flat plate) of the diaphragm 11 is pressed by the water pressure or the pressure is released (downward or upward) .

The water pressure is indicated by the atmospheric pressure, which increases in proportion to one atmospheric pressure every 10 m. 1 atmospheric pressure is 1.033227kgf / ㎠, and at a depth of 10m depth, it receives pressure of 2.06kg per 1cm2.

In the pressure switch device 10 of the present invention, it is preferable that the diameter of the diaphragm 11 is approximately 6 cm, which is 3 cm x 3 cm x 3.14 = 28.26 cm 2 in terms of area. If the pressure switch device 10 is located at a depth of 10 m, the total water pressure of the sensor becomes 2.06 × 28.26 = 58.21 cm 2, where the pressure of 29.19 kg is subtracted from the pressure of 1.033227 kgf / do.

In the diving operator accident location display device 1 using the hydraulic pressure and the conductivity according to the present invention, it is preferable to set the operation start water depth to 0.5 to 1.5 m. The reason is that the depth of 1m can be observed with the naked eye, and when the diving worker is resting periodically with Taekwag, the water depth based on the waist is about 0.5m and 100% tolerance is applied to the water depth of 0.5m So that the operation start water depth is preferably 0.5 to 1.5 m.

The water pressure when the operation start water depth of the diving operator accident location display device 1 is set to 1 m can be calculated as follows.

Assuming that the weight of 1 ml of water is 1 g, the total weight of water having a depth of 1 m and an area of 28.26 cm 2 is 28.26 cm 2 x 1 m = 2826 g. That is, the weight applied to the diaphragm 11 at a water depth of 1 m is 2826 g, which increases or decreases in proportion to the water depth.

The pressure applied to the diaphragm 11 presses the diaphragm 11 downward and the pressure plate 13 attached to the diaphragm 11 is also pushed downward.

When the pressure plate 13 is pushed (downward), the pressure switch 14 provided on the lower side of the pressure plate 13 is pressed and the pressure switch 14 is turned on. The operating pressure is determined by the tensile force and diameter of the diaphragm 11 and the elastic force of the spring (not specifically shown) of the pressure switch 14.

A conductivity meter 30 is provided on the side surface of the pressure switch case 12 installed on the outer surface of the buoy storage bag 500.

The conductivity measuring apparatus 30 is configured such that a pair of conductive electrode terminals 31 are mounted on the side surface of the pressure switch case 12 so as to be spaced apart from each other and spaced apart without covering the diaphragm 11, (Spaced apart from each other at an interval of preferably 5 to 8 cm) on the lower side of the side surface.

Preferably, the pair of conductive electrode terminals 31 are formed of stainless steel or platinum-gold electrodes usable in both fresh water and seawater, and the conductive electrode terminals 31 are formed in a circle having a diameter of 4 to 10 mm.

Each conductive electrode terminal 31 is electrically connected to the input sensor SEN 111 of the sensor input circuit 110 which is staked on the circuit board 15 inside the pressure switch case 12. [

The input sensor SEN 111 uses both the pressure switch device 10 and the conductivity measuring device 30 so that the pressure switch device 10 and the conductivity measuring device 30 The outputs are connected in series.

FIG. 6A is a diagram illustrating a portion related to the sensor input circuit 110 among the hydraulic pressure sensor unit 110. FIG.

The conductivity varies greatly depending on the state of the place where the diving operator is located. In addition, when the diving operator accident position indicating device 1 according to the present invention is stored, the conductivity may be exposed to high humidity.

In some products, it is not possible to exclude cases in which the device is operated due to sensor error, making it impossible to reuse or operating in a normal state to cause safety accidents.

Therefore, in the diving operator accident location display device 1 according to the present invention, a sensor comparator (U2: comparator comparator) is used to measure the conductivity, thereby eliminating the sensor error due to unbalanced conductivity.

In the diving operator accident location display device 1 according to the present invention, the sensor input circuit 110 of FIG. 6A has two main characteristics.

This includes a power supply portion for supplying a voltage to a voltage comparator U2 (comparator comparator) centered on the transistor Q2, a voltage comparator U2 for measuring the conductivity and supplying power to the microcomputer 200, ) Circuit.

The sensor input circuit 110 illustrated in FIG. 6A will now be described in more detail.

When a resistance value which is a reverse value of the conductivity is input to the input sensor 111, a current flows through the base of the transistor Q2. When a current flows through the base of the transistor Q2, a voltage appears at the emitter of the transistor Q2, Is the base voltage 0.66V.

For safe operation of the voltage comparator (U2: comparator comparator), a voltage of at least 1V is required, and the sensor input circuit 110 is designed to have a voltage of 4.5V.

In order to set the emitter voltage of the transistor Q2 to 4.5 V, a base voltage of 4.5 V + 0.66 V = 5.16 V is required. The resistance value of the sensor whose base voltage of the transistor Q 2 is 5.16 V is 9 V × 1 M / 5.16 V (R18) = 1.74 M OMEGA, and 1.74 M OMEGA - 1 M OMEGA (R18) - 400 OMEGA (R17) = 340 KM.

That is, if the resistance value, which is the inverse of the conductivity, is 340k or less, a voltage of 4.5V is supplied to a voltage comparator (U2: comparator comparator). The voltage comparator U2 (comparator comparator) to which the voltage is supplied, when the value of the input terminal is higher than the value of the + input terminal, the output becomes low to turn on the transistor Q3.

In order for the voltage comparator (U2: comparator comparator) to turn on the transistor Q3, the following condition must be satisfied.

The set value of the conductivity inputted to the input sensor 111 is based on the value of R19 (5.11 MΩ) / R20 (3.92 MΩ) = [conductivity + R3 (27.4 k)] / R4 (1.02 k).

The approximate value is [9V / (5.11 M OMEGA + 3.92 M OMEGA)] 3.92 M OMEGA = 3.91 V, 9 V 3.91 V = 5.09 V, and 5.09 V * 1.02 / 3.91 V = 1.33. 1.33 - 27.4 = 1.06. If the resistance value input from the input sensor 111 is 1.06 M OMEGA or less, it immediately operates.

As described in the formula, by adjusting the value of the resistor R4 (1.02 M OMEGA), the operating conductivity value of the input sensor 111 can be adjusted and used. This means that it is possible to manufacture the motion sensor 111 having a very high new road specific to a specific place.

The transistor Q3 is a PNP type transistor. When the base value is 0V, the transistor Q3 is turned on completely to perform the switching operation. 4.5 V of the battery is output to the collector of the transistor Q3 and charged to the mylar capacitor C2 and then 4.5 V is supplied to the microcomputer 210 of the microcomputer 200 And operates the microcomputer 210 (U1).

6B is a circuit diagram of the microcomputer 200. Fig.

The microcomputer 210 U1 measures the sensor input time and drives the solenoid 310 for punching the cartridge 320 for deploying the buoy 500 and measures the battery voltage and an LED .

The microcomputer unit 200 includes driving circuits R9 and R14 of the microcomputer U1, battery check circuits C4, R10 and R11, solenoid output circuits R12, R13, Q4 and D3, , Q5, and L1).

 When the input sensor 111 is activated and a voltage is supplied to the microcomputer unit 200, the microcomputer unit 200 measures the battery voltage. The battery voltage is measured using the analog terminal (terminal 10) of the microcomputer 210 (U1).

First, the battery voltage is divided at the battery check circuits C4, R10, and R11. The divided voltage is [battery voltage / (R10: 220 k? + R11: 100?)] X (R11 100 k?). When the battery voltage is 4.5 V, the divided voltage is (4.5 V / 330 k?) X 100 k? = 1.36 V, and when the battery voltage is 4.0 V, the divided voltage is 4.0 V / In the microcomputer 210 (U1), if the divided voltage is 1.21 V or less, the battery low voltage is judged.

When the battery voltage is measured, the battery status is displayed according to the result of the measurement. When the battery voltage is higher than 4.0 V (split voltage 1.21 V), LED (230, LED, LED) flickers a predetermined number of times (for example, twice) It is determined that the battery is low voltage and the LED (230, L1, LED) is turned off a predetermined number of times (for example, 30 times) and the operation is stopped.

When the display of the battery status using the LED (L1: LED) is finished, the time is measured. If the measured value is equal to or higher than the set value, the buoy 500 for accident indication and maintenance is developed.

The expansion of the buoy 500 drives the solenoid 310 of the cartridge unit 300 to forcibly open the cartridge 320 to the punching pin of the solenoid 310 (Carbon dioxide) that is filled in the gas.

 Since the time setting value of the microcomputer 210 (U1) can be set from several seconds to several tens of minutes, it is possible to customize each user and each place of use. When the operation time of the input sensor 111 is less than the set value, the microcomputer 210 (U1) is reset and initialized.

This operation means that the diving operator is able to repeatedly perform the water and water repeatedly within the set time of the sensor operation.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is evident that many alternatives, modifications and variations will be apparent to those skilled in the art.
