Currently fishing boats are required to have life jackets (life jackets) for the number of crew. Even if you wear lifejackets, if you do not rescue the distress quickly, it may lead to hypothermia accidents, so it is the most important point of the rescue to quickly recognize the distress accident. However, since the current lifeboat agreements for ships are thick and limited in activity, fishing companies are not usually able to wear lifejackets and there is no disaster rescue system using IT technology. There is a trend.

In the case of distress at sea, especially at night, the distance of searchlights is several hundred meters, and it is difficult to find the location of the distress due to bad weather or sea current movement.

In order to solve the difficulties of location detection in sea rescue, there have been many developments of personal distress rescue devices that can be tracked using GPS.

However, the current GPS receiver system receives satellite signals every few seconds, so the GPS receiver standby power is consumed considerably in the distress rescue terminal.

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

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

Preferably, according to one embodiment of the present invention, in the power off state, when the minimum power is supplied to the sensor unit 120 and the control unit 170, the moisture or salt concentration detected in the sensor unit 120 The controller 170 determines power supply. In addition, the controller 170 determines and controls the SOS mode according to whether or not to exceed or exceed a preset value of the power supply determination and the detected result value as follows.

The setting input unit 130 inputs a power on / off setting and an SOS on / off setting. The power on / off setting and the SOS on / off setting can be made using a button. Preferably, the on / off setting may use one button or two buttons.

The entry / exit report setting / release button is a setting button for wirelessly reporting the departure / and / or entry to the main device of the external reporting station.

Referring to FIG. 2, the GPS receiver 140 calculates a position coordinate by receiving a GPS satellite signal. Preferably, although not shown, it comprises a GPS receiving antenna for receiving GPS satellite signals and a GPS module for calculating position coordinates from the received signals. Since the GPS consumption unit 140 consumes a large number of satellite signals at intervals of several seconds, typically 1 to 2 seconds, the present invention reduces the power consumption of the GPS receiver 140 by discharging the battery of the distress position transmitter 10. Reduced consumption In the present invention, the GPS receiver 140 transmits a signal to the GPS satellites based on the latest position coordinates stored in the memory to receive the satellite signals from the GPS satellites so that the position coordinates can be found more quickly.

The RF communication unit 150 of FIG. 2 wirelessly transmits the distress signal to the outside and receives the radio signal from the outside. Although not shown, the RF communication unit 150 includes an RF receiving part for receiving a wireless signal from the outside and an RF transmitting part for transmitting the wireless signal to the outside. The RF communicator 150 may wirelessly transmit the distress signal generated by the controller 170 and may receive a wireless signal transmitted from an external server system although not shown. In the present invention, unless the server or external or external server or external server system is contrary to the contents, the main device or system, such as a land declaration, or / sea vessels and / and ships transmitting and receiving main device or system is applicable thereto. In the present invention, the RF communication unit 150 transmits a radio signal to such an external or external server system, and receives a radio signal from the outside. Therefore, the external wireless transmission through the RF communication unit 150 in the present invention can receive the signal of the distress in the surrounding vessels in conjunction with the vessel / fishing vessel position transmitter, such as AIS.

Preferably, the RF communication unit 150 may transmit data including time information synchronized with the external server system to enable location tracking in the external server system. For example, transmission is performed using a time division multiplexing (TDM) method. In addition, preferably, by receiving a radio signal transmitted from an external server system and carrying at least a portion of the time or / and registration information, it is possible to enable location tracking when synchronized or asynchronous with the external server system.

The memory unit 160 stores data including setting registration information and position coordinates calculated from the GPS receiver 140. The setting registration information is configured to be inputable through an application on an external computer such as a PC to which the distress position transmitter 10 is connected or through the distress position transmitter 10. Preferably, the distress location transmitter 10 is configured to input setting properties via an application on a wired or wireless, preferably wired, connected external computer terminal. The setting registration information includes a user ID and the like. Further, preferably, the setting registration information also includes a unique ID of the distress position transmitter 10. In one preferred embodiment, the unique ID of the distress location transmitter 10 and / or the setting input user ID of the setting registration information stored in the memory unit 160 is included when the distress signal or location information is generated by the controller 170. Will be sent to the outside. The memory unit 160 stores the latest position coordinates calculated by the GPS receiver 140.

Also, preferably, the memory unit 160 stores the movement route calculated from the stored position coordinates. At this time, the calculation of the movement route is made by the controller 170, and as a result, the movement route is updated and stored. The storage of the movement route is preferably stored with the time information. The stored movement path may be downloaded from an external computer connected to the distress position transmitter 10 when necessary. In addition, the memory unit 160 may store the distress signal transmission record and the movement route for a certain period of time, and preferably, the entrance and exit record may be stored for a predetermined period of time, and may be downloaded and connected to an external computer if necessary.

The controller 170 of FIG. 2 controls each component. In addition, the controller 170 determines and controls the SOS mode when a result value detected by the sensor unit 120 exceeds or exceeds a preset value or when an SOS on setting input from the setting input unit 130 is input. The preset value contrasted with the result value detected by the sensor unit 120 is preset and stored in the memory unit 160. For example, when the result detected by the sensor unit 120 relates to moisture detection, whether the sensor unit 120 is immersed in water such as seawater or fresh water for a predetermined time or more 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 several tens of seconds, or more. In addition, if the result detected by the sensor unit 120 relates to the salinity concentration, for example, it may be determined whether the SOS mode based on the salinity concentration range of seawater. In addition, in the case of the salt concentration, for example, it may be based on the concentration of the chloride ion, or 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 supply unit 110 to the GPS receiver 140 when determining the SOS mode. The GPS receiver 140 receives the satellite signal at a first predetermined interval according to the power supply control to calculate the position coordinates. As a result, the operation period or the interval of the GPS receiver 140 is controlled according to the power supply control from the controller 170 to the GPS receiver 140, and accordingly, the GPS satellite signal is continuously continuously maintained at intervals of several seconds, for example, 1 to 2 seconds. It is possible to reduce excessive power consumption by receiving. In addition, the control unit 170 stores the latest position coordinates received by the GPS receiver 140 in a memory, so that the GPS receiver 140 may receive the latest GPS satellite signal and use the same to calculate the position coordinates. Accordingly, the first interval for controlling power supply from the controller 170 to the GPS receiver 140 may be lengthened if there is no or slight variation with the latest position coordinate stored in the memory. For example, since there is little or no change in position during distress distressing due to small currents or waves, by increasing the first interval, it is possible to minimize battery consumption and to continuously transmit distress signals until distress rescue. In the present invention, the first interval and the following second to sixth intervals, etc. are merely for distinguishing the time intervals, and are irrelevant to whether the intervals are identical or not.

The control unit 170 also generates a distress signal including a latest position coordinate among the calculated position coordinates and the position coordinates stored in the memory unit 160 and the setting registration information stored in the memory unit 160 to generate an RF communication unit. Control to wirelessly transmit at a second predetermined interval through the 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, the GPS receiver 140 may shorten the second interval from the first interval in order to reduce power consumption in satellite signal reception and position coordinate calculation, and to increase the number of radio transmissions of the distress signal. When the second interval is shorter than the first interval, the latest position coordinates stored in the memory unit 160 may be more recent than the latest position coordinates calculated by the GPS receiver 140. At least a part of the setting registration information stored in the memory unit 160 preferably includes the unique ID of the distress location transmitter 10 and / or the setting input user ID. As a result, a distress signal including a distress position and information for identifying a distress person is generated and transmitted. For example, the distress position transmitter 10 unique ID or the user ID has already been reported to the relevant authority, and the data is used to identify the user.

In addition, the controller 170 stops the operation of the GPS receiver 140 by stopping the power supply of the GPS receiver 140 when it is not in the SOS mode, or controls the power supply from the power supply unit 110 to the GPS receiver 140. The GPS receiver 140 receives the satellite signal at a third predetermined interval longer than the first interval at the time of SOS mode determination to calculate the position coordinates.

In the case of the non-SOS mode, the power supply to the GPS receiver 140 may be interrupted to stop the operation of the GPS receiver 140 to minimize power consumption. This method is advantageous when the distress location transmitter 10 is used purely for distress rescue. In addition, it is suitable for fishermen who avoid location tracking due to exposure of fisheries location, etc., and the battery use time is long.

In addition, the power is supplied to the GPS receiver 140 in another manner, and the power supply interval to the GPS receiver 140 is longer, thereby reducing power consumption of the GPS receiver 140. The reason why the third interval is longer than the first interval in this embodiment is that the distress position transmitter 10 must be maintained to supply power from the battery even in an unexpected emergency. In other words, in the non-SOS mode, the power consumption is kept to a minimum so that the distress signal can be sufficiently transmitted in the SOS mode. The latter method may be useful for distress position transmitter 10 to monitor location information in addition to the purpose of distress rescue. In addition, it is possible to narrow down the search range by estimating the missing point by roughly identifying the location of the distress who failed to send SOS in case of emergency. In case of movement, it may be suitable for confirming the information of the trailing fishing boat from the leading fishing boat. For example, although not shown, the external server system may be useful for periodically or intermittently monitoring the position of the distress position transmitter 10 or monitoring the position within the fishing vessel tip group. In the latter method, for example, the third interval may range from several minutes to several tens of minutes. Alternatively, the time interval may be longer than that. For example, when the vehicle is in 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, when not in the SOS mode, for example, in the case of wirelessly transmitting the location information for entry and exit reporting, etc., the position coordinates may be calculated by supplying power to the GPS receiver 140 at intervals of several tens of seconds or more. Can be.

When the controller 170 supplies power to the GPS receiver 140 at a third interval, the controller 170 may be configured to provide the latest position coordinates and the memory unit 160 among the calculated position coordinates and the position coordinates stored in the memory unit 160. By generating the location information including at least a portion of the stored setting registration information to control the wireless transmission at the fourth predetermined interval longer than the second interval through the RF communication unit 150. 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 position transmitter 10 and / or a setting input user ID.

In addition, according to another embodiment of the present invention, in the case of transmitting a distress signal or transmitting location information, the controller 170 receives the position coordinates calculated by the GPS receiver 140 and the memory unit 160. If there is no change in coordinates between the latest position coordinates stored in or less than a predetermined reference, the GPS receiver 140 receives a satellite signal at an interval longer than the first interval or at an interval longer than the third interval, and supplies power to calculate the position coordinate. The wireless terminal may be configured to wirelessly transmit the distress signal or the position information including the calculated position coordinates at intervals longer than the second or fourth intervals. That is, by comparing the latest position coordinates calculated by the GPS receiver 140 with the latest position coordinates pre-stored in the memory unit 160, if there is no change in coordinates of the position coordinates or is below a predetermined reference, power consumption is increased by increasing the GPS reception interval. It can be minimized. In addition, it is possible to reduce the power consumption by longer intervals for transmitting the distress signal or location information wirelessly. The implementation of such a function in the controller 170 may be implemented by a preset program, and a detailed description of the configuration of such a program may be easily implemented by a programmer based on the above description, and thus will be omitted. do.

Preferably, also in one embodiment, the third interval or / and the fourth interval is narrowed when the speed is increased by judging the change between the positional coordinates, and the third interval or / and the third when the speed is slowed. It is also possible to variably control four intervals.

In addition, preferably, according to another embodiment of the present invention, the control unit 170 receives the satellite signal from the GPS receiver 140 at intervals that gradually increase from the first interval when determining the SOS mode to determine the position coordinates. The power supply is controlled to calculate and wirelessly transmits the distress signal including the calculated positional coordinates at intervals that gradually increase from the second interval. According to this embodiment, the distress signal is frequently sent at the beginning of the SOS mode situation, but by increasing the time interval later, the distress signal including location information can be continuously transmitted to the last rescued situation while reducing battery consumption. It is to ensure that.

Look at another embodiment of the present invention. The GPS receiver 140 may not receive a GPS satellite signal. For example, when there is an object on the upper part of the distress position transmitter 10 that prevents satellite signal reception, or when the user cancels the GPS mode for calculating the GPS position to reduce the GPS reception standby power, the arrival time or arrival time of the RF signal is reached. This is the case when the RF mode which performs position tracking by time difference is set. In this case, when determining the SOS mode, the control unit 170 generates a distress signal including a current time and at least a part of the setting registration information stored in the memory unit 160 to control the wireless transmission through the RF communication unit 150. .

This method applies a location tracking technique based on a time of arrival (TOA) or a time difference of arrival (TDOA), and measures a radio wave arrival time from a mobile terminal, for example, the distress location transmitter 10 according to the present invention. A positioning algorithm with TOA or TDOA data in a way to measure the distance between the servers is used to track the position of the distress location transmitter 10 in a location service center, such as an external server system. This method can be calculated synchronously or asynchronously by calculating the absolute time from the distress position transmitter 10 to at least three external servers and tracking the position. The synchronous method is the distress position transmitter 10 and the server mutually. In a synchronous system, the distress position transmitter 10 in a synchronous method records an absolute current time and sends a signal to an external server. This signal reaches each server in the vicinity of the distress position transmitter 10. Since the external server and the distress position transmitter 10 synchronize the current time, the external server has an absolute arrival time for the received signal. It can be calculated, using the distance for this time to calculate the position for the distress position transmitter (10).

Alternatively, when the GPS receiver 140 does not receive the GPS satellite signal, the controller 170 may reply to the signal from the external server system received by the RF communicator 150 and set registration information stored in the memory 160. Generates a distress signal including at least a portion of the control to wirelessly transmit through the RF communication unit 150. In the present 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 by at least three servers in the vicinity to calculate the position. An example of such a method is synchronous but asynchronous. In the asynchronous manner, 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, the distress location transmitter 10 immediately sends a response signal to the external server. In this case, preferably, at least three external servers that receive signals from the distress location transmitter 10 are time synchronized. Of course, even if there is no time synchronization between the servers. 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.

In order to examine the position calculation method by the synchronous or asynchronous method, first, the formula for calculating the distance according to the arrival time of the radio wave based on one external server is d (distance) = c (speed of radio wave) × t ( Time).

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

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

Or, using the distance information d1, d2, d3 calculated by the equation d = c × t, three circles having a radius with respect to the distress position transmitter 10 from three external servers and three circles in common There is a method of selecting the intersection area where the distress position transmitter 10 is located. In this method, the entire area where the circle intersects is determined as the position of the distress position transmitter 10 to indicate the position of the distress position transmitter 10 as a result.

In addition, in the non-SOS mode, in the case of wirelessly transmitting the location information, the control unit 170 may include the location information including the current time and at least some of the setting registration information stored in the memory unit 160, or the RF communication unit ( The controller 150 generates location information including reply information about the signal received from the external server system received at 150 and at least a part of the setting registration information stored in the memory unit 160 and wirelessly transmits the information through the RF communication unit 150.

In this embodiment, the server, the external server, and the external server system, although not shown, forms a network with the distress position transmitter 10 as a device or system installed on the ground or / and the ship, and serves as a server for the distress position transmitter 10. If it works, that's enough.

According to the present embodiment, GPS satellite signals are not received in the conventional location tracking devices using GPS, thereby overcoming the problem of accurate location tracking.

In addition, referring to 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 longer than a preset time. Thus, the controller 170 determines and controls the SOS mode according to the power-on command and the SOS on setting.

In another embodiment, in the power off state, when the minimum power is supplied to the sensor unit 120 and the control unit 170 and the moisture or salt concentration is detected at the sensor unit 120, the control unit 170 may determine whether to supply power. do. Thus, the controller 170 determines and controls the SOS mode according to whether or not the power supply is determined and the detected result value is equal to or greater than a preset value.

According to these embodiments, the distress signal may be easily or automatically generated / transmitted even in a sudden distress situation.

5 is a flow chart illustrating a location and SOS transmission process in one embodiment of the distress location transmitter of FIG. 1.

Referring to Figure 5, looks at the position of the distress position transmitter 10 and the SOS transmission process. 5 is shown for illustrative purposes only, and the present invention should not be construed as being limited thereto.

First, basic information is set, and terminal ID, sensor, and battery (Bat.) Are basically set, and then channel is set. When the GPS button is set to the ON state, for example, it waits for about 3 seconds to receive the GPS, and determines whether the SOS button is ON. If the SOS button is not set, it is operated in the position transmission mode to determine whether GPS reception is fixed. When the GPS is fixed, the GPS is synchronized and the TDM slot is allocated, and location information transmission is started at a fourth interval, for example, 5 to 30 minutes. If the GPS is not fixed, receive a signal from the main unit and synchronize it with the main unit. In addition, if the sound wave transmitting unit 180 is provided, it synchronizes with the main apparatus, transmits an acoustic signal, and transmits basic information for the TOA without position information at a fourth interval, for example, 5 to 30 minutes.

In Fig. 5, if the SOS button is in the ON state, the terminal operates in the 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, a 10 second period. If the GPS is not fixed, it receives a signal from the main unit, synchronizes with the main unit, and transmits an audio signal. In addition, basic information for the TOA is transmitted at a second interval, for example, at 10 second intervals without location information.

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

Referring to FIG. 3, according to one embodiment of the present invention, the distress position transmitter 10 further includes a sound wave transmitter 180 for transmitting a sound wave signal corresponding to the distress signal. By providing a sound wave transmitting unit 180 to transmit a sound wave signal, even if the user wearing the distress rescue equipment of the present invention is locked in the water by a fish detector or sonar equipment that is used in a general fishing boat without a dedicated receiver It is to receive a signal to receive a distress signal. The sound wave signal generated by the sound wave transmitter 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 the purpose of combating sharks, or some or all thereof according to an embodiment of the present invention. have.

In the present embodiment, the control unit 170 generates a sound wave signal corresponding to the distress signal when determining the SOS mode, and controls to transmit at a fifth predetermined interval through the sound wave transmitter 180. The fifth interval may be the same or different than the second interval. Preferably, when the sensor unit 120 is detected as being submerged in water, the control unit 170 transmits a sound wave signal more frequently than the second interval or only a sound wave signal instead of wireless transmission through the RF communication unit 150. You can make a call.

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

4 shows a schematic block diagram of yet another embodiment of the distress location transmitter of FIG.

Referring to FIG. 4, according to an embodiment of the present invention, the distress location transmitter 10 may relay distress signals received from another distress location transmitter 10 received through the RF communication unit 150 to form a wireless ad hoc network. It further comprises a wireless routing unit 190. According to the present embodiment, the transmission / reception rate between the distress position transmitter 10 and the main device of the ship or the land is increased. According to the present embodiment, the distress signal may be relayed to a land base station or a ship located in a distant place, and thus the distress signal may be used as a medium for propagating the communication distance and spreading an emergency situation. Therefore, it is possible to carry out the effect of increasing the communication distance and quick situation propagation and quick rescue by relaying the distress signal in connection with the neighbor distress position transmitter 10 or the vessel position transmitting device of the nearby ship.

Preferably, the distress position transmitter 10 according to an embodiment of the present invention relays distress signals in conjunction with a neighbor distress position transmitter or a vessel position transmitting device of a nearby ship, and increases communication range and rapid situation propagation. It is possible to perform a quick rescue, and if the nearby ship is located in a remote communication area that is unable to communicate with the main device or difficult to communicate with the main device, it may be configured to perform communication with the main device using a terminal (relay terminal) provided in another ship. have. Here, the relay terminal transmits a communication relay between the distress position transmitter 10 or the terminal of the ship (or vessel position transmitting device) relaying the communication of the distress position transmitter 10 and the terminal of another vessel relaying communication to the main apparatus or the main apparatus. Refers to a terminal to perform. The relay function of the ship's relay terminal is similar to that of the distress position transmitter 10 including the wireless routing unit 190 according to one embodiment of the present invention. That is, the terminal provided in each ship is added with a relay function for relaying communication between the terminal and the main device of the other ship, the distress position transmitter 10 or the relay terminal is different when the self-ship is located in a remote or shadowed area The communication is performed using the ship's relay terminal, and when there is a relay request from another ship, the communication between the terminal of the other ship and the main device is relayed.

According to one embodiment of the present invention, 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 position transmitter 10 is not activated or fixed for a long time, the distress position transmitter 10 is synchronized by a signal from the main apparatus. Preferably, since the transmission using TDM multiplexing, the self-transmission timing of the terminals in the communication range of the main apparatus is different. For example, the self transmission timing is divided by 200 ms intervals, and the time slot causes the last 1 byte × 200 ms point of the RF ID of the terminal itself to be the self transmission timing. That is, when the magnetic RF ID is 01020304, the relay RF ID and the magnetic RF ID are transmitted at the point of 04 × 200ms = 800ms as shown in the following table.

Here, the relay RF ID is an RF ID of another terminal when the distress location transmitter 10 receives a radio signal from another terminal when performing the relay function by the wireless routing unit 190. Each RF ID is for example terminal unique IDs.
