Description

Distress location transmitter provided in a life jacket and a distress rescue system using the same {EMERGENCY POSITION TRANSMITTER WITH LIFESAVING CLOTHES AND ACCIDENT RESCUE SYSTEM USING IT}

The present invention relates to a distress location transmitter provided in a life jacket and a distress rescue system utilizing the same.

Currently, it is mandatory for fishing boats to provide life jackets (life jackets) according to the number of people on board. Even if a lifejacket is worn, failure to quickly rescue a person in distress can lead to a hypothermic accident. Therefore, recognizing the fact of a marine accident and quickly dispatching the victim can be said to be the most important point in marine rescue. However, because the marine lifejackets currently in use are thick and have many restrictions on activities, which hinders fishing, fishermen are unable to wear lifejackets on a regular basis, and since a disaster rescue system using IT technology has not been established, domestic marine accidents increase every year. There is a trend.

In case of distress at sea, especially at night, the identification distance of searchlights is short (hundreds of meters) and it is difficult to determine the location of the person in distress due to bad weather or moving ocean currents, making rescue rates for drowning accidents and searches for missing persons very difficult.

In order to solve the difficulty of determining location in marine rescue, etc., a lot of development is being conducted on personal distress rescue devices that can track location using GPS.

However, a typical GPS reception system currently receives satellite signals at intervals of several seconds, so a significant amount of GPS reception standby power is consumed in the distress and rescue terminal.

Accordingly, in cases where it is difficult to determine the location at night or when it takes a long time to arrive at a distress rescue due to movement of ocean currents, a problem occurs in which the distress rescue terminal does not have sufficient remaining battery power.

Additionally, when a person in distress is submerged in water, a wireless signal containing location information is not transmitted, making it difficult to determine the location of the person in distress.

In addition, because conventional marine lifejackets were thick and had many restrictions on movement, which hindered operations, accidents involving failure to wear lifejackets frequently occurred.

The present invention is intended to solve at least one of the problems described above, and provides a distress location transmitter installed in a life jacket that can transmit a distress signal for a long time by dramatically reducing the consumption of GPS reception standby power, and a distress rescue system using the same.

In addition, by mounting a distress location transmitter on a slim, high-buoyancy lifejacket according to one aspect, a distress location transmitter provided in a life jacket that does not interfere with fishing activities and is convenient to wear, and a distress rescue system using the same are provided.

Shows a block diagram, Figure 3 shows a schematic block diagram according to another embodiment of the distress location transmitter of Figure 1, and Figure 4 shows a schematic block diagram according to another embodiment of the distress location transmitter of Figure 1 It represents degrees.

Looking at an embodiment of the present invention with reference to FIG. 1, it relates to a distress location transmitter (10) provided in a high-buoyancy rescue suit (30) in which a storage space (31) is formed. The high-buoyancy rescue suit 30 shown in FIG. 1 can be modified into various embodiments. For example, the high-buoyancy rescue suit 30 has a storage space 31 formed on one upper side, and the distress location transmitter 10 can be stored in the storage space 31. Also, preferably, the high-buoyancy rescue suit 30 is made of multiple layers of low-density polyethylene foam resin to make it slim, highly buoyant, and excellent in winterization. Also, preferably, high-brightness reflective fabric is attached in the form of a strip on the back or/and front to facilitate identification by lighting at night.

Referring to FIGS. 2 to 4, the distress location transmitter 10 in FIG. 1 includes a power supply unit 110, a sensor unit 120, a setting input unit 130, a GPS receiver 140, an RF communication unit 150, and a memory unit. It includes (160) and a control unit (170).

The power supply unit 110 supplies power. Preferably, the power supply unit 110 includes a battery or a rechargeable battery.

More preferably, the power supply unit 110 includes a charging interface, and even more preferably can be charged using a general mobile phone charger. Also, preferably, the charging interface can be waterproofed by an openable and closed waterproof case.

The sensor unit 120 detects moisture or salt concentration. The salt concentration is detected by measuring the concentration of chlorine ions or other salts in the liquid in contact with the sensor unit 120.

Preferably, according to one embodiment of the present invention, in a power-off state, minimum power is supplied to the sensor unit 120 and the control unit 170, and when moisture or salt concentration is detected in the sensor unit 120. The control unit 170 determines whether to apply power. And the control unit 170 determines and controls the SOS mode according to the power application decision and whether the detected result value is above or beyond a preset value, as follows.

The settings input unit 130 inputs power on/off settings and SOS on/off settings. Power on/off settings and SOS on/off settings can be made using buttons. Preferably, the on/off setting can be done using one button, or two buttons can be used.

Preferably, according to one embodiment of the present invention, the setting input unit 130 generates a power-on command when the SOS on setting button is pressed for more than a preset time in a power-off state. At this time, the control unit 170 determines and controls the SOS mode according to the power-on command and SOS on setting.

Also, preferably, in one embodiment of the present invention, although not shown, the setting input unit 130 further includes an entry/exit port report setting/release button. The port entry/exit report setting/release button is a setting button for wirelessly reporting port departure or/and entry to the external reporting station.

Referring to FIG. 2, the GPS receiver 140 receives GPS satellite signals and calculates location coordinates. Preferably, although not shown, it includes a GPS receiving antenna that receives GPS satellite signals and a GPS module that calculates location coordinates from the received signals. Since the GPS receiver 140 consumes a lot of power when receiving satellite signals for several seconds, usually at intervals of 1 to 2 seconds, the present invention reduces the power consumption of the GPS receiver 140 to save the battery of the distress location transmitter 10. It reduces consumption. In the present invention, the GPS receiver 140 transmits a signal to a GPS satellite based on the latest location coordinates stored in memory and receives satellite signals from the GPS satellite, thereby enabling the location coordinates to be found more quickly.

The RF communication unit 150 in FIG. 2 wirelessly transmits a distress signal to the outside and receives a wireless signal from the outside. The RF communication unit 150, although not shown, consists of an RF receiving part that receives wireless signals from the outside and an RF transmitting part that transmits wireless signals to the outside. The RF communication unit 150 may wirelessly transmit a distress signal generated by the control unit 170 and, although not shown, may receive a wireless signal transmitted from an external server system. In the present invention, the server or external or external server or external server system may be a main device or system such as a reporting station on land, or/a transmitting/receiving main device or system of a ship or/and ship at sea, unless it is contrary to its contents. The RF communication unit 150 in the present invention transmits a wireless signal to an external or external server system and receives a wireless signal from the outside. Therefore, in the present invention, external wireless transmission through the RF communication unit 150 is linked with a ship/fishing vessel location transmitting device such as AIS, so that the distressed person's signal can be received from surrounding ships.

Preferably, the RF communication unit 150 may transmit data including time information synchronized with an external server system to enable location tracking in the external server system. For example, it is transmitted using the TDM (Time Division Multiplexing) method. Also, preferably, a wireless signal transmitted from an external server system is received and returned including at least part of the time and/or registration information, thereby enabling location tracking when synchronized or unsynchronized with the external server system.

The memory unit 160 stores data including setting registration information and location coordinates calculated from the GPS receiver 140.

The setting registration information is configured so that settings can be input through the distress location transmitter 10 or through an application on an external computer such as a PC to which the distress location transmitter 10 is connected. Preferably, the distress location transmitter 10 is configured to input setting registration information through an application on a wired or wireless, preferably external computer terminal connected by wire. Setting registration information includes user ID, etc. Additionally, preferably, the setting registration information also includes a unique ID of the distress location transmitter 10. In one preferred embodiment, the unique ID of the distress location transmitter 10 and/or the user ID entered among the configuration registration information stored in the memory unit 160 are included when generating a distress signal or location information in the control unit 170. It is transmitted externally. The memory unit 160 stores the latest location coordinates calculated by the GPS receiver 140.

Also preferably, the memory unit 160 stores the movement path calculated from the stored position coordinates. At this time, the movement path is calculated by the control unit 170, and the movement path is updated and stored as a result. The movement route is preferably stored together with time information. The saved movement route can be downloaded from an external computer connected to the distress location transmitter 10 when necessary. Also preferably, the memory unit 160 can store distress signal transmission records and movement routes for a certain period of time, and preferably also stores entry and exit records for a certain period of time, and can be downloaded by connecting to an external computer when necessary.

And the control unit 170 of FIG. 2 controls each component. In addition, the control unit 170 determines and controls the SOS mode when the result detected by the sensor unit 120 is greater than or exceeds a preset value or when the SOS on setting is input from the setting input unit 130. A preset value compared to the result value sensed by the sensor unit 120 is preset and stored in the memory unit 160. For example, if the result detected by the sensor unit 120 is related to moisture detection, whether the sensor unit 120 is immersed in water such as seawater or fresh water for a predetermined period of time may be a criterion for determining the SOS mode. In this case, the predetermined time may be set in the range of several seconds to tens of seconds, or may be longer. Additionally, if the result detected by the sensor unit 120 is related to salinity concentration, for example, the SOS mode can be determined based on the salinity concentration range of seawater.

Additionally, in the case of salt concentration, for example, it may be based on chlorine ion concentration, or it may be based on the concentration of other salts.

In particular, in one embodiment of the present invention, the control unit 170 controls the power supply from the power unit 110 to the GPS receiver 140 when determining the SOS mode. According to power supply control, the GPS receiver 140 receives satellite signals at a preset first interval and calculates location coordinates. Ultimately, the operation cycle or interval of the GPS receiver 140 is controlled according to the power supply control from the control unit 170 to the GPS receiver 140, and accordingly, GPS satellite signals are usually continuously transmitted at intervals of several seconds, for example, 1 to 2 seconds. Excessive power consumption due to receiving can be reduced. In addition, the control unit 170 stores the latest position coordinates received and calculated from the GPS receiver 140 in memory, thereby allowing the GPS receiver 140 to receive the latest GPS satellite signals and use them to calculate location coordinates. Accordingly, the first interval during which the control unit 170 controls the power supply to the GPS receiver 140 can be long when there is no or insignificant change from the latest location coordinates stored in the memory. For example, in the case of a marine distress with little ocean current or waves, there is little or no change in location, so by lengthening the first interval, battery consumption can be minimized and continuous distress signal transmission can be made possible until distress rescue. In the present invention, the first interval and the second to sixth intervals in the following are only used to distinguish time intervals, and are unrelated to whether the intervals are the same, whether there is a difference in the length of the intervals, or the order of the interval lengths.

The control unit 170 also generates a distress signal including the calculated location coordinates, the latest location coordinates among the location coordinates stored in the memory unit 160, and at least part of the setting registration information stored in the memory unit 160, and sends a distress signal to the RF communication unit. Controls wireless transmission at a preset second interval through (150). The first interval for supplying power to the GPS receiver 140 and the second interval for wireless transmission through the RF communication unit 150 may be the same or different. For example, in order to reduce power consumption in receiving satellite signals and calculating location coordinates in the GPS receiver 140 and increase the number of wireless transmissions of distress signals, the second interval can be made shorter than the first interval. When the second interval is shorter than the first interval, the latest location coordinates stored in the memory unit 160 may be more recent than the latest location coordinates calculated by the GPS receiver 140. At least a portion of the setting registration information stored in the memory unit 160 preferably includes a unique ID of the distress location transmitter 10 and/or a user ID entered as a setting.

Accordingly, a distress signal containing information that can identify the distress location and the person in distress is generated and transmitted. For example, the unique ID or user ID of the distress location transmitter 10 has already been reported to the relevant authorities and becomes data that can identify the user.

In addition, the control unit 170 stops the operation of the GPS receiver 140 by stopping the power supply to the GPS receiver 140 when not in the SOS mode, or controls the power supply from the power unit 110 to the GPS receiver 140. Thus, the GPS receiver 140 receives satellite signals at a preset third interval that is longer than the first interval when determining the SOS mode, and location coordinates are calculated.

In cases other than the SOS mode, power consumption can be minimized by stopping the operation of the GPS receiver 140 by first cutting off the power supply to the GPS receiver 140. This method is beneficial when the distress location transmitter 10 is used purely for distress rescue purposes. In addition, it is suitable for fishermen who avoid location tracking due to concerns about exposure to fishing grounds, etc., and has a long battery life.

Additionally, power consumption in the GPS receiver 140 can be reduced by supplying power to the GPS receiver 140 in another way, but making the power supply interval to the GPS receiver 140 longer. The reason why the third interval is longer than the first interval in this embodiment is that the distress location transmitter 10 must be maintained so that power can be supplied from the battery even in unexpected emergencies. In other words, when not in SOS mode, power consumption is kept to a minimum to ensure that a distress signal can be sufficiently transmitted in SOS mode situations. The latter method may be useful in allowing the distress location transmitter 10 to monitor location information for purposes other than distress rescue. In addition, in the event of an emergency, the location of a person in distress who was unable to send an SOS can be roughly identified and the search area can be narrowed by estimating the point of disappearance. Therefore, it can be used by Coast Guard vessels to confirm the location of suppression agents such as Chinese fishing boats, or by making a front line such as double fishing boats. When moving, it may be suitable for checking information on deviating fishing boats behind the leading fishing boat. For example, although not shown, it may be useful when periodically or intermittently monitoring the location of the distress location transmitter 10 from an external server system or when monitoring within a fishing boat fleet group. In the latter method, for example, the third interval may range from minutes to tens of minutes. Or it may be a longer time interval. For example, in the case of operation, the time interval may be longer. In some cases, an interval of several tens of seconds longer than the first interval is possible. Preferably, in cases other than SOS mode, for example, when location information is transmitted wirelessly for reporting ports of entry, etc., power is supplied to the GPS receiver 140 at intervals of tens of seconds or more to calculate location coordinates. You can.

When power is supplied from the control unit 170 to the GPS receiver 140 at the third interval, the control unit 170 selects the latest location coordinates among the calculated location coordinates and the location coordinates stored in the memory unit 160 and the memory unit 160. Location information including at least part of the stored setting registration information is generated and controlled to be wirelessly transmitted through the RF communication unit 150 at a preset fourth interval that is longer than the second interval. The third interval for supplying power to the GPS receiver 140 and the fourth interval for wireless transmission through the RF communication unit 150 may be the same or different. In addition, at least a portion of the setting registration information stored in the memory unit 160 preferably includes a unique ID of the distress location transmitter 10 and/or a user ID entered as a setting.

In addition, according to another embodiment of the present invention, when transmitting a distress signal or transmitting location information, the control unit 170 receives and calculates the location coordinates from the GPS receiver 140 and the memory unit 160. If there is no coordinate change between the latest location coordinates stored in the , or the coordinates are below a predetermined standard, power is supplied to calculate the location coordinates by receiving satellite signals from the GPS receiver 140 at an interval longer than the first interval or at an interval longer than the third interval. Control and control to wirelessly transmit a distress signal or location information including the calculated location coordinates at an interval longer than the second or fourth interval. That is, by comparing the latest location coordinates calculated by the GPS receiver 140 with the latest location coordinates previously stored in the memory unit 160, if there is no change in the coordinates of the location coordinates or the coordinates are below a predetermined standard, the GPS reception interval is lengthened to reduce power consumption. It can be minimized. Additionally, power consumption can be reduced by lengthening the interval between wireless transmission of distress signals or location information. Implementation of these functions in the control unit 170 may be implemented by a preset program, and a detailed description of the configuration of such a program will be omitted since it can be easily implemented by a programmer based on the above description. do.

Preferably, in one embodiment, the change between position coordinates is determined to narrow the third interval or/and the fourth interval when the speed increases, and the third interval or/and the fourth interval when the speed decreases. 4 The interval can also be controlled to be long and variable.

Also, preferably, according to another embodiment of the present invention, when determining the SOS mode, the control unit 170 receives satellite signals from the GPS receiver 140 at gradually longer intervals from the first interval and provides the location coordinates. The power supply is controlled to calculate, and the distress signal including the calculated position coordinates is controlled to be transmitted wirelessly at intervals that gradually become longer from the second interval.

According to this embodiment, distress signals are sent frequently in the early stages of the SOS mode situation, but the time interval becomes longer as time goes by, thereby reducing battery consumption and continuously sending distress signals including location information until the final rescue situation. It is intended to be so.

Let's look at another embodiment of the present invention. There are cases where the GPS receiver 140 cannot receive GPS satellite signals. For example, if there is an object that interferes with satellite signal reception on top of the distress location transmitter 10, or if the user disables the setting of the GPS mode that calculates the GPS location to reduce standby power for GPS reception, the arrival time or arrival time of the RF signal is changed. This is the case when RF mode is set to track location by time difference. In this case, when determining the SOS mode, the control unit 170 generates a distress signal including the current time and at least part of the setting registration information stored in the memory unit 160 and controls the signal to be transmitted wirelessly through the RF communication unit 150. .

This method applies a location tracking technique by TOA (Time Of Arrival) or TDOA (Time Difference Of Arrival), and measures the radio wave arrival time from a mobile terminal, for example, the distress location transmitter 10 of the present invention, and connects the terminal to the terminal. A location determination algorithm with TOA or TDOA data as a way to measure the distance between servers is used to track the location of the distress location transmitter 10 in a location service center, for example, an external server system. This method is an algorithm that tracks the location by calculating the absolute time from the distress location transmitter 10 to at least three external servers. It can be calculated synchronously or asynchronously. In the synchronous method, the distress location transmitter 10 and the servers are connected to each other. In a synchronized system, in the synchronous method, the distress location transmitter 10 records the absolute current time and sends a signal to an external server. This signal reaches each server around the distress location transmitter 10, and since the external server and the distress location transmitter 10 synchronize the current time, the external server determines the absolute arrival time for the received signal. can be calculated, and the position of the distress location transmitter 10 is calculated using the distance for this time.

Alternatively, when the GPS receiver 140 cannot receive a GPS satellite signal, the control unit 170 sends response information to the signal from the external server system received by the RF communication unit 150 and the setting registration information stored in the memory unit 160. A distress signal containing at least part of is generated and controlled to be transmitted wirelessly through the RF communication unit 150. In this embodiment, the external server system may be a system including one server or multiple servers, and the signal from the external server system may be a signal from one server or a signal from at least three servers. Preferably, in this embodiment, the signal transmitted through the RF communication unit 150 is received from at least three nearby servers to calculate the location. As an example of this method, synchronous method is possible, but asynchronous method is also possible. In the asynchronous method, time synchronization between all external servers and the distress location transmitter 10 is not necessarily required. The external server records the current time and sends a signal to the distress location transmitter 10, and the distress location transmitter 10 sends a response signal to the external server as soon as it receives the signal. In this case, preferably, at least three external servers receiving signals from the distress location transmitter 10 are time-synchronized. Of course, this is possible even if time is not synchronized between each server. The external server calculates the distance using the time difference between the arrival time of the signal sent from the distress location transmitter 10 and the previously stored signal.

To examine the location calculation method using a synchronous or asynchronous method, first of all, the formula for calculating the distance according to the arrival time of radio waves based on one external server is d (distance) = c (speed of radio waves) × t ( time).

For example, an example of a formula for calculating the location of the distress location transmitter 10 through TOA or TDOA received from at least three external servers is as follows. Here, d1, d2, d3 are the distances between each external server and the distress location transmitter 10, and (x1, y1), (x2, y2), (x3, y3) are the x, y coordinates of each external server. , and (Xm, Ym) are the x, y coordinates of the distress location transmitter 10.

The location coordinates of the distress location transmitter 10 can be obtained by using the d1, d2, and d3 distance information calculated by the equation d = c × t.

Or, using the d1, d2, d3 distance information calculated by the equation d = c There is a method of selecting the intersection area encountered as the location of the distress location transmitter 10. In this method, the entire area where the circle intersects is determined as the location of the distress location transmitter 10 to indicate the location of the distress location transmitter 10 as a result.

In addition, in cases other than the SOS mode, when location information is transmitted wirelessly, the control unit 170 provides location information including the current time and at least part of the setting registration information stored in the memory unit 160, or the RF communication unit ( Position information including response information for the signal from the external server system received at 150 and at least part of the setting registration information stored in the memory unit 160 is generated and controlled to be transmitted wirelessly through the RF communication unit 150.

In this embodiment, the server, external server, and external server system are not shown, but are devices or systems installed on the ground and/or on a ship that form a network with the distress location transmitter 10 and serve as a server for the distress location transmitter 10. It's enough if it works.

According to this embodiment, the problem that accurate location tracking is difficult in conventional location tracking devices using GPS because GPS satellite signals are not received is overcome.

Additionally, looking at another embodiment of the present invention, in the power-off state, the setting input unit 130 generates a power-on command when the SOS on setting button is pressed for more than a preset time. Therefore, the control unit 170 determines and controls the SOS mode according to the power-on command and SOS on setting.

In another embodiment, in a power-off state, minimum power is supplied to the sensor unit 120 and the control unit 170, and when moisture or salt concentration is detected in the sensor unit 120, the control unit 170 determines whether to apply power. do. Accordingly, the control unit 170 determines and controls the SOS mode according to the power application decision and whether the detected result value is above or beyond a preset value.

According to these embodiments, it is possible to easily or automatically generate/transmit a distress signal even in a sudden distress situation.

FIG. 5 is a flowchart showing the location and SOS transmission process in one embodiment of the distress location transmitter of FIG. 1.

Referring to FIG. 5, the location of the distress location transmitter 10 and the SOS transmission process will be examined. Figure 5 is an exemplary illustration for understanding the invention, and the invention should not be construed as limited thereto.

First, basic information is set and the terminal ID, sensor, and battery (Bat) are set as default, and then the channel is set. And when the GPS button is set to ON, for example, it waits for about 3 seconds to receive GPS and determines whether the SOS button is ON. If the SOS button is not set, it operates in location transmission mode and determines whether GPS reception has been fixed. When the GPS is fixed, a TDM slot is assigned by synchronizing with the GPS, and location information transmission is started at a fourth interval, for example, every 5 to 30 minutes. If the GPS is not fixed, it receives the signal from the control device and synchronizes it with the control device. In addition, if the sound wave transmitting unit 180 is provided, it synchronizes with the host device and transmits an acoustic signal, and also transmits basic information for TOA without location information at a fourth interval, for example, every 5 to 30 minutes.

In Figure 5, if the SOS button is ON, the terminal operates in SOS transmission mode. If the GPS is fixed in the SOS transmission mode, it synchronizes with the GPS, allocates a TDM slot, and starts SOS transmission at a second interval, for example, at a period of 10 seconds.

If the GPS is not fixed, it receives a signal from the control panel, synchronizes it with the control panel, and transmits an audio signal. In addition, basic information for TOA without location information is transmitted at a second interval, for example, every 10 seconds.

FIG. 3 shows a schematic block diagram of another embodiment of the distress location transmitter of FIG. 1.

Referring to FIG. 3, according to one embodiment of the present invention, the distress location transmitter 10 further includes a sound wave transmitting unit 180 that transmits a sound wave signal corresponding to a distress signal. By providing a sound wave transmitter 180 to transmit a sound wave signal, even if a user wearing the distress rescue equipment of the present invention is submerged underwater, the user can easily use the fish finder or sonar equipment used in general fishing boats, etc., without a dedicated receiver. It is designed to receive signals and receive distress signals. Depending on the embodiment of the invention, the sound wave signal generated from the sound wave transmitting unit 180 may be an acoustic signal such as a buzzer sound, a sound wave signal that can be received by sonar equipment, an ultrasonic signal for purposes such as shark expulsion, or part or all of them. there is.

In this embodiment, when determining the SOS mode, the control unit 170 generates a sound wave signal corresponding to a distress signal and controls the sound wave signal to be transmitted at a preset fifth interval through the sound wave transmitter 180. The fifth interval may be the same or different from the second interval. Preferably, when the sensor unit 120 detects that the sensor unit 120 is submerged in water, the control unit 170 transmits the sound wave signal more frequently than the second interval or transmits only the sound wave signal instead of wireless transmission through the RF communication unit 150. You can have it sent.

In addition, preferably, in another embodiment of the present invention, the control unit 170 controls the sound wave transmitter 180 to generate a preset shark repellent sound wave signal when determining the SOS mode, and the sound wave transmitter 180 Under the control of the control unit 170, a shark repellent sound wave signal is transmitted at a preset sixth interval. The sixth interval may be the same or different from the fifth interval.

Figure 4 shows a schematic block diagram according to another embodiment of the distress location transmitter of Figure 1.

Referring to FIG. 4, according to an embodiment of the present invention, the distress location transmitter 10 relays distress signals from other distress location transmitters 10 received through the RF communication unit 150 and forms a wireless ad hoc network. It further includes a wireless routing unit 190. According to this embodiment, the transmission and reception rate between the distress location transmitter 10 and the host device on a ship or on land is increased. According to this embodiment, the distress signal is relayed and transmitted to a land base station or ship located in a distant location, thereby increasing the range and can be used as a medium to spread emergency situations. Therefore, it is possible to relay the distress signal in conjunction with the neighboring distress location transmitter 10 or the vessel location transmitter of a nearby vessel, thereby increasing the range, quickly disseminating the situation, and performing rapid rescue.

Preferably, the distress location transmitter 10 according to an embodiment of the present invention relays the distress signal in conjunction with a neighboring distress location transmitter or a vessel location transmitter of a nearby vessel, thereby increasing the range and quickly disseminating the situation. Rapid rescue can be performed, but if a nearby vessel is located at a long distance where communication with the main unit is not possible or in a communication shadow area where communication is difficult, it can be configured to communicate with the main unit using a terminal (relay terminal) provided on another vessel. there is. Here, the relay terminal relays communication between the distress location transmitter 10 or a terminal on the ship (or a ship location transmitter) that relays the communication of the distress location transmitter 10 and the main device or a terminal on another ship that relays communication to the main device. Refers to the terminal performing the operation. The relay function of the ship's relay terminal is similar to the function of the distress location transmitter 10 including the wireless routing unit 190 according to one embodiment of the present invention. In other words, the terminal provided on each ship is added with a relay function that can relay communications between the terminal and the main device of other ships, and the distress location transmitter (10) or relay terminal is used to communicate with other ships when the own ship is located in a remote or shaded area. Communication is performed using the ship's relay terminal, and if there is a relay request from another ship, the communication between the other ship's terminal and the main device is relayed.

According to one embodiment of the present invention, we will look at the data transmission format when the distress location transmitter 10 performs a wireless relay function. When the GPS receiver 140 of the distress location transmitter 10 is not activated or is not fixed for a long time, the distress location transmitter 10 is synchronized by a signal from the main device. Preferably, since transmission is performed using TDM multiplexing, the self-transmission timing of terminals within the communication range of the host device is different. For example, the self-transmission timing is divided into 200ms intervals, and at this time, the time slot is set so that the last 1 byte × 200ms of the terminal's own RFID is the self-transmission timing. In other words, if the magnetic RFID is number 01020304, it is transmitted at 04×200ms = 800ms, including the relay RF ID and magnetic RF ID as shown in the table below.

RFID data format Startup code Relay RFID magnetic RFID Error check exit code

This is the RF ID of another terminal when a wireless signal is received from another terminal. Each RFID is, for example, a terminal's unique ID.

Let's look at another embodiment of the present invention. Although not shown, according to this embodiment, the distress location transmitter 10 is provided with a buoyancy rescue case, and a storage space 31 for the high-buoyancy rescue suit 30 and the distress location transmitter 10 are provided inside or outside the buoyancy rescue case. ) is provided with a sturdy string of a certain length connecting the. The buoyancy rescue case is for allowing the distress location transmitter (10), which has fallen into the storage space (31) of the high-buoyancy lifejacket (30), to float to the surface when the distress rescue equipment of the present invention is submerged in water, and is provided with a line of a predetermined length. This connection allows the distress location transmitter 10 to float on the surface of the water, while the user wearing winter clothing is submerged in the water, and the exact location can be found even if the user or the vessel in the water moves over time due to currents, etc. A predetermined length of line wrapped around the inside or outside of the buoyancy structure case is released when the distress location transmitter 10 rises to the surface by the buoyancy structure case and is connected to the storage space 31 of the winter clothing, preferably several tens of meters. It is wound to a length of In addition, preferably, the distress location transmitter 10, which has a predetermined line wrapped around the inside or outside of the buoyancy structure case, is separated into the storage space 31 of the high buoyancy rescue suit 30 and mounted on the user's general clothing and stored in a predetermined manner. A length of string can be connected to regular clothing and used. Accordingly, in the event of a ship accident, a person sinks below the water's surface without wearing a lifejacket, or sinks below the water's surface with the ship despite wearing a lifejacket, which prevents wireless transmission using GPS or causes the user to be washed away by the ocean current below the water's surface. This helps solve the problem of location tracking.

Let's look at another embodiment of the present invention.

Preferably, in another embodiment of the present invention, the control unit 170 sets the periodic received field strength (RSSI) from the host device of the external report received through the RF communication unit 150 in the power-on state to a value greater than or equal to a preset value. If the range gradually becomes smaller, it is judged as departure report mode, and if it gradually becomes larger, it is judged as port arrival report mode. In this embodiment, the external reporting station refers to an onshore reporting station, a sea vessel, patrol boat, or fishing guidance vessel that can receive or/and confirm port of entry reports, and the main unit confirms the port of entry by transmitting/receiving a wireless signal for wireless port of entry reporting. It refers to a transmitting and receiving device that transmits or relays.

In this embodiment, the port of entry reporting mode is performed automatically, and is based on the port of entry zone virtually formed on the outskirts of the port on the electronic chart on the main device of the external reporting center or the server system connected to it. This is a method of judging entry into port.

In the departure report mode of this embodiment, location information is periodically transmitted wirelessly until the received electric field strength falls below a preset value or until a signal corresponding to the completion of the departure report is received from the main device of the external reporting station. And in port entry report mode, location information is periodically transmitted wirelessly until a signal corresponding to completion of port entry report is received from the external reporting station's main device. After the received electric field strength falls below a preset value or after receiving a signal corresponding to the completion of the departure report, or more preferably after receiving a signal corresponding to the completion of the departure report, the departure report mode is released, and the port arrival report is completed. After receiving the corresponding signal or after the received electric field strength rises above a preset value, or more preferably after receiving the signal corresponding to the completion of the port entry report, the port entry report mode is controlled to be released.

According to this embodiment, the effectiveness of the distress location transmitter 10 can be increased and the convenience of fishermen in reporting ports of entry and exit can be improved.

Meanwhile, preferably, although not shown, according to another embodiment of the present invention, the setting input unit 130 of the distress location transmitter 10 is provided with an entry/exit port report setting/release button. In this embodiment, the control unit 170 determines the port of entry mode according to the entry and exit port report settings input from the settings input unit 130, periodically transmits location information wirelessly in the port entry and exit mode, and reports the port of entry and exit from the settings input unit 130. Depending on the release input or upon receiving a signal corresponding to the completion of the port of entry report from an external reporting center, it is determined to be in a state other than the port of entry mode and is controlled. In addition, preferably, when a signal corresponding to the completion of the entry/exit port report is received from an external reporting center, it is displayed in the form of audio or/and text or/and a buzzer sound, and the entry/exit port mode is released.

Also preferably, according to another embodiment of the present invention, although not shown, the distress location transmitter 10 is provided with a LOCK key in the setting input unit 130 to prevent inadvertent input of the SOS on setting. . In addition, although not shown, the distress location transmitter 10 is provided with a communication check button in the settings input unit 130, so that it is possible to check the communication performance of the distress location transmitter 10 and/or check whether the current location is within the communication area. there is. In addition, although not shown, the battery remaining amount can be checked by providing a battery remaining amount alarm sound or/and a battery remaining amount LED warning lamp or/and a battery remaining amount LCD window.

The remaining battery capacity can also be displayed in percent on the LCD window.

Let's look at another embodiment of the present invention. According to one embodiment, the storage space 31 of the high-buoyancy rescue suit 30 is formed on one upper side and accommodates the distress location transmitter 10. The high-buoyancy lifesaving suit 30 is provided with a buoyancy filler made of low-density polyethylene foam resin, and the buoyancy filler is formed in multiple layers in a sheet form. Preferably, low-density polyethylene foamed resin, unlike lifejackets that use general PE foam, NBR, EVA, etc. as buoyancy materials, is made by mixing low-density polyethylene with a foaming agent, a mold release agent, and a surfactant and going through melting, curing, foaming, and cooling processes, and then using a high-magnification extrusion method. It is manufactured. Low-density polyethylene foam has excellent buoyancy compared to general buoyancy materials, and is manufactured in a thin sheet form so that even when made in multiple layers, it does not cause inconvenience to the wearer's activities and can be worn without restrictions even during fishing activities. Accordingly, conventional marine lifejackets are thick and have many restrictions on activities, which helps prevent accidents caused by failure to wear lifejackets that interfere with fishing operations.

Also, more preferably, the thickness of each sheet-like filler layered in multiple layers is 0.5 to 1 mm. For example, even if sheets with a thickness of 0.5 to 1 mm are stacked in 4 to 8 layers, they are much thinner than the pad thickness of a typical life jacket of about 2.5 to 3.5 cm, so they do not interfere with activities such as fishing.

Next, we will look at specific embodiments of a distress rescue system using a distress location transmitter provided in a life jacket according to another aspect of the present invention.
