Description

[0001] INTELLIGENT UNDERWATER DANGER DETECTION SYSTEM COMPRISING SMART DIVING SUIT [0002]

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to an intelligent underwater risk sensing system including a smart wetsuit, and more particularly, to a smart wetsuit including a human body signal sensing sensor and an intelligent underwater risk sensing system for informing a diver underwater risk through a sensor signal .

Due to the continued growth of the leisure sports industry, scuba diving has also been on the rise since 1968 when it was deployed from the military to the private sector. In the early days, it was difficult to popularize it due to expensive equipment. However, due to the development of the Internet, a large number of clubs have been created and the related population has started to increase and it is estimated that it is in the range of 30 ~ 350 thousand.

In addition, due to the increase in college diving clubs, the University Diving Association has been launched in 2015, and young delegates are actively involved. In addition to the diving association, there are various educational programs such as expansion of related education programs, The diving population is expected to increase steadily.

At the government level, the "Law on the Promotion of Leisure under the Sea" will be launched in 2014 to provide legal basis for the underwater leisure industry. In addition, in order to expand the base of underwater leisure, a national skin scuba experience program, Leisure festivals and so on.

As mentioned above, the marine leisure industries are being actively fostered by the Ministry of Maritime Affairs and Fisheries, and the diving sector is considered as the most promising field in the industry. Also, considering that the increase in the leisure sports population led to the rapid growth of the leisure sports equipment market, the diving equipment market is expected to grow in the future as well, and it is necessary to develop diving equipment or rescue system to secure safety.

Because of the nature of underwater work, diver workers are more isolated from the outside than working in groups. In addition, since it works in water such as ocean or river, activity is not free, and breathing depends on oxygen cigarette, so brain activity is lowered and it is difficult to cope with surrounding danger factors (lack of oxygen, dangerous marine life, fast bird). Therefore, there is a need to apply safety equipment or advanced equipment to the wetsuit for safety of underwater divers and safer underwater activities.

The diving equipment sector is growing along with the leisure industry, which has been growing for several years. Therefore, the development of high-tech wetsuits considering the safety of divers are active in this market trend.

Domestic diving accidents have caused a total of 102 deaths in the past seven years. In Korea, the number of deaths per 10,000 diabetics is 0.56, which is two to three times higher than that of developed countries such as the United States and Japan. The analysis of the causes of diving accidents (2000 ~ 2013) by domestic year is classified into 7 major causes such as diver error, lack of education, environmental factors, safety accident, and ship collision (Marine Police Internal Affairs - 2014).

Among them, 19.3% were accidental accidents and 1.93% were underwater environmental factors. As a result of combining the results of the diving accidents by the above-mentioned period, it is estimated that 281 deaths occurred in 310 of the accidents, and most of them died when the diving accident occurred. Therefore, there is a desperate need for accident prevention. However, the diversity of the marine environment is diverse and there are many times when the diver threatens to cope with it, so prevention through education is limited.

Therefore, in order to cope with the diving accident, it is necessary to provide a supplementary measure to quickly detect and cope with the diver's life, and it is the most realistic way to install the diving equipment.

Although it is difficult to find in Korea now, underwater radio communication equipment has been developed and marketed in developed countries such as USA and Europe. Nautilus's lifeline radio is available for connection to neighboring boats through international distress channel, And transmits the rescue request message to the boats within a short time.

Another product is SOYE's ENOS, which consists of a portable GPS positioning system, a monitor and a transmitter, allowing the diver to be located on the surface of the boat.

However, the above products belong to expensive diving equipment. Underwater wireless communication technology is not reliable due to frequent malfunction due to wave and water temperature.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, an intelligent underwater danger detection system including a smart wetsuit according to an embodiment of the present invention will be described in detail with reference to the drawings.

1 is a conceptual diagram of an intelligent underwater danger detection system including a smart wetsuit according to an embodiment of the present invention.

2 is a functional block diagram of an intelligent underwater risk detection system according to an embodiment of the present invention.

1 and 2, an intelligent underwater risk sensing system according to an embodiment of the present invention includes a smart wetsuit 100, a float 200, and a communication linking the smart wetsuit 100 and the float 200, And a cable 300.

The smart wetsuit 100 is a garment to be worn at the time of diving, and when the human body comes into contact with water, heat is absorbed more quickly than the human body in the air. For this reason, the wet suit is a device that must be worn for the purpose of maintaining the temperature of the human body in the water constantly and is worn for the purpose of physically protecting the human body from rough environment. The wet suit will form a thin film between the body and the wet suit, preventing cold water from escaping the body heat.

The smart wetsuit 100 according to an embodiment of the present invention includes a human body signal sensing sensor 110 as well as a function inherent to such a wet suit, so that the heart rate, blood pressure, or body temperature of the diver is checked in real time.

2, the smart wetsuit 100 includes a human body signal detection sensor 110 and a controller 120. [ The controller 120 receives a signal from the human body signal sensing sensor 110 to determine the presence or absence of a diver and sends a rescue signal to the float 200 on the water surface when a human body abnormality occurs in the diver.

The controller 120 may be implemented in a chip form, and may include a memory or the like. In particular, it is integrally formed with the battery 120 that supplies power to the controller 120 and the human body signal detection sensor 110, and can be waterproofed so as not to be exposed to water.

The controller 120 will be described in detail below.

The float 200 receives a structural signal transmitted from the controller 120 through the buoy 210 and the communication cable 300 and transmits the structural signal of the diver to the wireless communication unit 220 for wirelessly transmitting the distress signal of the diver. A light emitting unit 230 that receives and emits light, and an acoustic unit 240 that receives the structural signal of the diver and emits the acoustic signal.

The buoy 210 is a structure that styrofoam or enclosed space is filled with air to withstand the weight of hundreds of kilograms and floats on the surface at all times. The shape of buoys can be formed into a structure that is most influenced by buoyancy at the water surface in general.

The wireless communication unit 220 includes various communication modules such as 3G, 4G, Wibro, WiFi, bluetooth, and Zigbee, but is not limited thereto. The communication modules constituting each wireless communication unit 220 mainly mean a transmission module, and may include a reception module. Further, the wireless communication unit 220 may be operated by its own power source, and may be connected to the power source generating unit to use wave power, wind power, and solar power as a power source.

The light emitting unit 230 may use a low power light source such as an LED, and the power source of the LED light may be supplied using its own power source or various renewable energy sources. However, the present invention is not limited thereto.

The acoustic unit 240 may be a speaker that outputs sounds ranging from several tens to several hundreds of dB up to a long distance. In order to prevent interference of frequencies, it is preferable to output sound so as to have a wavelength range different from that of the wave sound.

The controller 120 according to an embodiment of the present invention receives a signal from the human body signal sensor 110, which is checked whether the heart rate, blood pressure, or body temperature is abnormal, and determines whether or not the diver is abnormal. If an abnormality of the diver is found, the structural signal is transmitted to the float 200 through the communication cable 300.

3 is a functional block diagram of a controller according to an embodiment of the present invention.

As shown in FIG. 3, the controller 120 includes a user interface 121, a timer 122, and a wired port 123.

The user interface 121 allows the diver to input an abnormality occurrence reference heart rate, blood pressure, or body temperature. Generally, the normal heart rate varies slightly with age depending on sex. For men, 70-76 times per minute is normal, and for women, 73-78 times per minute is normal. The diver's normal heart rate may vary depending on the sex and age of the diver, so that the abnormal heart rate may vary for each diver. Therefore, in order to finely classify the abnormality occurrence criteria, the diver's normal heart rate is input, You can set it yourself. The blood pressure and the body temperature can also be input by themselves through the user interface 121, which is a reference for the blood pressure and the abnormal body temperature, which are standards for the abnormal blood pressure of the user.

The timer 122 determines the duration of the abnormality occurrence reference heart rate, blood pressure, or body temperature of the diver. Even if an abnormal symptom is caught in the diver, it may return to the stable state soon. In this case, the actual controller 120 does not need to transmit the rescue signal because the abnormality reference heart rate, blood pressure, or body temperature lasts for a short time.

If the diver is not present for a predetermined period of time or if the diver is not recovering to a normal state, the controller 120 determines the measured duration at the timer 122 to generate a rescue signal and send it to the float 200 Can be transmitted.

The wired port 123 transmits a structural signal generated by the controller 120 to the float 200 connected to the communication cable 300. The wired port 123 may be, but is not limited to, an Ethernet wired communication port that supports RS232, a COM port. The wired port and connection area are configured to be waterproof.

The controller 120 may also selectively control the wireless communication unit 220, the light emitting unit 230, or the acoustic unit 240 of the float 200 according to the degree of abnormality of heart rate, blood pressure, or body temperature of the diver. For example, if the diver's heart rate is rapidly rising, but the body temperature or blood pressure is normal, it is possible to control the alarm to sound only in the acoustic part so that a person at a distance from the diver diving area can recognize it. When both of the heart rate signals are captured, a warning is generated due to the capture of an abnormal symptom of the diver in the wireless communication unit 220, the light emitting unit 230, and the acoustic unit 240.

4 is a functional block diagram of a float according to an embodiment of the present invention.

4, the float 200 according to the embodiment of the present invention includes not only the wireless communication unit 220, the light emitting unit 230, and the acoustic unit 240 described above, but also the reel A reel 250, and a motor 260 for rotating the reel.

The controller 120 rotates the motor 260 to wind the communication cable 300 on the reel when the heart rate, blood pressure, or body temperature of the diver is detected.

The input port 270 is connected to the communication cable 300 and may be the same kind of port as the wired port 123 of the controller 120 described above.

The controller 120 controls the rotation speed of the motor 260 according to the diver's heart rate, blood pressure, or abnormality degree. For example, if it is determined that an abnormality has occurred in the heart rate and blood pressure of the diver, the rotation speed of the reel 250 can be controlled quickly.

The intelligent underwater risk sensing system according to the present invention continuously detects the heart rate, blood pressure or body temperature by the human body signal sensor 110 included in the smart wetsuit 100 to which the diver wears, A structure signal of the diver is transmitted to the float 200 in the case where it is out of the standard and the float 200 requests the structure using the wireless communication unit 220, the light emitting unit 230 or the acoustic unit 240, The reel 250 included in the float 200 and the motor 260 for rotating the reel 250 are rotated so that the communication cable 300 is wound up to raise the diver to the water surface.

This intelligent underwater risk detection system allows the diver to automatically determine anomalous signs without requesting any other manipulation or structural signal request, and can request a rescue request or move on the surface of the water, thus preparing for a diver's safety accident.
