Description

  The present invention relates to a victim search and rescue support system, a victim search and rescue support method, a rescue tag, a life preserver, a remote management system, a remote management method, and a management tag, for example, a person or a mountain thrown from a ship to the sea due to an accident or the like. It is suitable to be applied to search and rescue victims such as those who are lost at an early stage, or to grasp and manage the position, movement, etc. of livestock such as cattle and other various items from a distant position. is there.

  Conventionally, for example, when a person is thrown into the sea due to an accident or fall of a ship at sea, it is possible to immediately go to rescue when a sailor etc. notices it, but when a sailor etc. does not notice it Rescue may be significantly delayed. In addition, if the ship capsizes, rescue may be significantly delayed unless the crew can give a distress signal.

  In preparation for such a case, conventionally, a disaster rescue support system using GPS signals (see Patent Document 1) and a search system using GPS signals (see Patent Document 2) have been proposed. The distress rescue support system of Patent Document 1 includes a mobile terminal that transmits accident occurrence information, position information, and time information in the event of a accident, a host computer that manages this mobile terminal, and these mobile terminals. And a communication means for linking the host computers. Then, the accident occurrence information is transmitted to the host computer as the first wave at the same time when the portable terminal is activated, and the position information is transmitted to the host computer as the second wave after receiving the positioning information (GPS signal) by the positioning satellite, and the time information is transmitted. Is included in the 1st and 2nd waves as the accumulated time since the mobile terminal was activated, and is transmitted to inform the rescue agency of the occurrence of the accident, request for search and rescue activities, and provide the location information of the victims. And so on. In this disaster rescue support system, it is described that a portable terminal is provided in a life jacket worn by a victim as an example in the case of a marine accident. Further, the search system of Patent Document 2 is mounted on a search target person, and a search target module that transmits at least the position information acquired from the GPS system to the surroundings and a peripheral area of the search target module in a two-dimensional manner at predetermined intervals. While receiving the signals that are distributed and sent from the search target module, multiple relay modules that build a network with other distributed modules by a relay method, and signals that are transmitted from multiple relay modules And a computing device that receives any one of them, computes the network construction state based on the positional relationship between the search target module and the relay module from the received signal, and acquires the location information of the search target module via the network, Rescue the person to be searched. In this search system, as an example in the case of assuming a marine accident, it is described that the search object module is provided in a life jacket worn by a victim.

  On the other hand, when grazing livestock such as cattle on a grazing land, a grazing livestock remote management system is known as a system for grasping the position of the livestock in real time from a position distant from the grazing livestock (see Patent Document 3). .. In this grazing livestock remote management system, for example, a cow is attached with a collar and grazing on a pasture. This collar is a GPS receiver that receives radio waves from GPS satellites and outputs data such as the current position, and the desired data is extracted from the data from this GPS receiver and is preset in the extracted data. A position data generator that sends out a moving position signal (cow position data) to which a cow identification code is added, a wireless device that transmits cow position data from this position data generator, and a power supply unit that supplies power to these ing. The power supply unit supplies power to the GPS receiver once every 10 to 20 minutes. Therefore, the cow radio data is transmitted every 10 to 20 minutes from the collar radio. On the monitoring center side, the position of itself is obtained based on the radio waves from the GPS satellites, and the cow position data is received, and the image processing device of the monitoring center is based on the difference with the position of the cow that matches the reception time of the cow position data. Then, the position of each image of the map of the pasture is moved on the screen, and a point image based on the cow position data is displayed on the map.

  However, the disaster rescue support system of Patent Document 1 not only becomes a large-scale system because it requires a communication satellite, a satellite earth station, and a network management station as communication means for linking the portable terminal and the host computer. It is considered that the power consumption of GPS receivers and communication devices of portable terminals is large. Therefore, in order to enable the portable terminals to be used for a long period of time, a heavy battery with a large capacity has to be used, and the user needs to use a heavy battery. There is a problem that the burden is heavy. Further, the search system of Patent Document 2 is considered not only to have a complicated system, but also to consume a large amount of power such as the GPS receiver and communication device of the search target module, thus making the search target module usable for a long period of time. Therefore, there is no choice but to use a heavy battery having a large capacity, and there is a problem that the burden on the user is heavy.

  Further, in the grazing livestock remote management system of Patent Document 3, since the GPS receiver is supplied with power once every 10 to 20 minutes, the power consumption of the GPS receiver can be reduced. Since the position data generator and the wireless device are always supplied with power while the power of the main unit is on, it is considered that the battery of the power supply needs to have a considerably large capacity, so the power supply is inevitable. The weight of the part is inevitably large, and therefore the weight of the collar is considered to be considerably large. For this reason, the cattle will be heavily burdened and there is a high possibility of giving unnecessary stress. In addition, even if such a large-capacity battery is used, the GPS receiver, the position data generator, and the entire wireless device consume a large amount of power, so that the battery must be frequently replaced, which is troublesome. It is thought to hang.

  Therefore, the problem to be solved by the present invention is to remotely and accurately grasp the position, movement, etc. of a victim in distress due to an accident in the sea, mountains, etc., and to save lifesaving equipment used by the victim. The power consumption of the rescue tag attached to the victim can be significantly reduced, which reduces the weight of the battery attached to the rescue tag and reduces the weight of the rescue tag and the frequency of battery replacement. It is an object of the present invention to provide a victim search and rescue support system, a victim search and rescue support method, and a rescue tag and a life preserver used therefor.

  Another problem to be solved by the present invention is to remotely and accurately grasp and manage the position and movement of livestock such as cattle grazing on a pasture, and more generally various managed objects in near time. In addition, it is possible to significantly reduce the power consumption of the asset tag attached to the object to be managed, thereby reducing the capacity of the battery attached to the asset tag and reducing the weight of the asset tag and the battery. When the object to be managed is an organism such as livestock such as cattle, which can significantly reduce the frequency of replacement, there is no risk of giving unnecessary stress to the remote management system and remote management method and It is to provide the management tags used.

In order to solve the above problems, the present invention provides

The communication device is turned off, and then the communication device is turned on to transmit the position information from the communication device at the time t ₃ or time t ₄ before and after the time t ₃ , and then the communication device is turned off at the time t ₅ , and then the communication device is turned off. At time t ₆ , the power source is put into a sleep state and this sleep state is continued until time t ₇ , and the time from time t ₁ to time t _{6 is} within 10 minutes, and from time t ₁ to time t ₇ It is a victim search and rescue support system configured to perform repeated operations.

The configurations of the GPS receiver, the communication device, the processing device, and the power source, which are the components of the rescue tag, are not particularly limited, and may be configured by individual elements, or any two or more of them may be integrally configured. You can choose it according to your needs. For example, the communication device and the processing device may be integrated into one chip. In this victim search and rescue support system, the GPS receiver is used in a cold start state. In this victim search and rescue support system, from the viewpoint of suppressing the power consumption of rescue tag, rescue tag is preferably the power is turned on at time t _1, the time from the time t ₁ within 10 milliseconds At t ₂ , the GPS receiver is turned on to start measurement, and at time t ₃ immediately after the first position information is acquired from the GPS signal, the GPS receiver is turned off, and the time t ₃ or the time t ₃ is reached. the positional information transmitted from the communication device before and after the time t ₄ as an on said communication device, the communication device is turned off at time t ₅ within 5 seconds from the time t ₃ or the time t _4, the time the power to continue the sleep state time t ₇ to more than one second as a sleep state from t ₅ to time t ₆ within one second, the time from the time t ₁ to the time t ₆ and within 5 minutes, the The operation is repeated from time t ₁ to time t ₇ .

Evacuation centers, etc.) or mounted on aircraft such as helicopters. Then, for example, after the position information transmitted from the communication device of the rescue tag is received by the relay device, the position information is transmitted from the relay device to a search and rescue organization that searches and rescues the victim. The search and rescue organizations are, for example, fishery cooperative associations, Coast Guard, police, etc. on water, and police, mountain rescue teams, etc. on land. Especially when the victim is a water victim, the location of the victim often changes due to the flow of water, etc., so even if the search is performed based on the location information first transmitted from the communication device, it will be discovered. It may take some time to get there. In order to prepare for such a case, it is preferable that the search / rescue agency receives the position information transmitted from the communication device of the rescue tag at the time when the relay device mounted on the ship received, and the vicinity of the disaster site at the time. From the weather information (wind direction, wind speed, etc.) and water flow information (flow direction, flow speed, etc.), the position of the rescue tag attachment target at any time after that time is predicted by computer simulation, and a search and rescue team is formed. Send. By doing so, it is possible to shorten the time required to search for a victim, and to rescue the victim quickly. Victims include not only those who have been distressed by accidents in the sea or mountains, but also, for example, elderly people who are wandering due to dementia and the like, and children who have lost their way.

  The rescue tag is stored in a container, especially a closed container, preferably a waterproof container in order to prevent damage or flooding, and the container is built in the rescue tag wearing target or the rescue tag wearing target. Attached to the outside, for example.

  The rescue tag attachment target may be basically any object, but examples thereof include a life preserver, mountaineering equipment, and a victim. The life preserver is, for example, a life jacket, a life buoy, a life boat, or the like. Mountaineering products are, for example, waist bags, jackets, jumpers, rainwear, rucksacks and the like. The parts and method of attaching the rescue tag to life preservers, mountaineering equipment, victims, etc. are selected as necessary.

If necessary, the power of the rescue tag 20 housed inside the capsules 14e, 15b can be turned on / off by a switch attached outside the capsules 14e, 15b.

  As will be described in detail later, the rescue tag 20 has a GPS receiver, a processing device (processor), and a communication device, and receives GPS signals transmitted from a plurality of GPS satellites 30 forming the global positioning satellite system by the GPS receiver. The processing device acquires the position information (latitude, longitude) of the rescue tag wearing target 10 from this GPS signal, and transmits the position information thus acquired to the outside by the communication device. The position information thus transmitted from the communication device of the rescue tag 20 is received by the repeater 40 and recorded in the built-in memory (not shown). The repeater 40 may basically be any type as long as it has the functions of receiving, recording and transmitting position information. The relay device 40 can use wireless equipment mounted on various ships such as fishing boats, passenger ships, excursion ships, and surveillance ships of the Fisheries Agency on the water, or can be installed separately. The wireless equipment provided in the facility (fishery cooperative, mountain facility, etc.) can be used, or it can be provided separately. The repeater 40 is installed in a mountain hut, an evacuation center, etc. in the mountains. The position information recorded in the memory of the repeater 40 is transmitted to the search / rescue agency 50 wirelessly or by wire and received by the search / rescue image display device provided in the search / rescue agency 50. Then, the image of the search area and the position of the rescue tag wearing target 10 in the search area are displayed on the screen of the image display device. If necessary, map information provided on the Internet can be displayed on the screen of the image display device, and the position of the rescue tag attachment target 10 may be displayed on the map information. The search and rescue organization 50 is a fishery cooperative association, the Coast Guard, the police, etc. on the sea, and the police, etc. on the land. As the GPS satellite 30, most preferably, a quasi-zenith satellite of the quasi-zenith satellite system "MICHIBIKI" capable of obtaining a positioning accuracy of several cm at the maximum is used, but the GPS satellite 30 is not limited to this.

  FIG. 4 shows details of the rescue tag 20. As shown in FIG. 4, the rescue tag 20 has a GPS receiver 22, a processing device 23, a communication device 24, a battery 25 constituting a power supply, a power supply regulator 26, and a power supply regulator 27 on a substrate 21. Although illustration is omitted, the GPS receiver 22 is provided (or connected) with an antenna, and the GPS signal can be received by this antenna. Although not shown, the communication device 24 is also provided (or connected) with an antenna so that a signal can be transmitted by this antenna. The GND terminal of the processing device 23, the GND terminal of the power supply regulator 26, and the GND terminal of the power supply regulator 27 are connected to the negative electrode of the battery 25, and the VCC terminal of the processing device 23, the VCC terminal of the power supply regulator 26, and the VCC terminal of the power supply regulator 27 are connected to each other. It is connected to the positive electrode of the battery 25 via the switch 28. When the switch 28 is closed, the voltage of the battery 25 is applied between the GND terminal and the VCC terminal of the processing device 23, between the GND terminal and the VCC terminal of the power supply regulator 26, and between the GND terminal and the VCC terminal of the power supply regulator 27, respectively. . A voltage regulated by the power supply regulator 26 is applied between the GND terminal and the VCC terminal of the GPS receiver 22, and the stabilized voltage is applied. Further, between the GND terminal and the VCC terminal of the communication device 23, a voltage that is stepped up or down and stabilized by the power supply regulator 27 is applied. The supply of electric power to the power supply regulator 26 and the power supply regulator 27, that is, the supply of electric power to the GPS receiver 22 and the communication device 24 is controlled by a control signal sent from the CTR terminal of the processing device 23. . The switch 28 connected to the battery 25 can be turned on / off manually with a button or the like. The switch 28 may be omitted and the battery 25 may be attached and the power may be turned on at the same time. It is controlled by a control signal sent from the CTR terminal of the processing device 23. Details of this control method will be described later. The data input / output terminals RD and SD of the GPS receiver 22 are connected to the data input / output terminals RD and SD of the processing device 23, respectively. The data input / output terminals RD and SD of the communication device 24 are connected to the data input / output terminals RD and SD of the processing device 23, respectively. The number of the batteries 25 may be one or plural, may be a primary battery or a secondary battery, and is selected as necessary depending on the use of the rescue tag 20. In applications where importance is attached to the lightness of the rescue tag 20, for example, three or four AA batteries are used as the battery 25, and the rescue tag 20 has low power consumption, so that the rescue tag 20 can be used for a long period of time even in this case. You can continue to use.

[How to operate the search and rescue support system for victims]
The rescue tag 20 is attached to the rescue tag attachment object 10. The mounting method of the rescue tag 20 is appropriately selected according to the rescue tag mounting target 10, such as the method shown in FIGS. 2 and 3.

  The power of the rescue tag 20 (main body) may be turned on / off by the victim or may be automatically set. For example, when a distressed person with a life jacket wearing the rescue tag 20 is thrown out from a ship at sea, the distressed person closes the switch 28 to turn on the power of the rescue tag 20 (main body). Alternatively, an acceleration sensor or the like detects a shock when a victim in a life jacket wearing the rescue tag 20 is thrown from the ship at sea, and the switch 28 is turned on by the detection signal, or the life jacket is in seawater. It is possible to automatically turn on the switch 28 by detecting the landing of water by utilizing a chemical reaction when it comes into contact with, and turning on the switch 28 by the detection signal. When the switch 28 is turned on in this way, the processing device 23 is turned on, and the operation of the victim search and rescue support system is started. Specifically, the control signal sent from the CTR terminal of the processing device 23 controls the power on / off of the GPS receiver 22 and the communication device 24.

FIG. 5 shows the on / off timings of the power supplies of the GPS receiver 22, the processing device 23, and the communication device 24. As shown in FIG. 5, the power is turned on at time t ₁ . The GPS receiver 22 is turned on and measurement is started in a cold start state within 10 milliseconds from the time t ₁ , preferably within 5 milliseconds, for example, at time t ₂ . When the measurement is started, the GPS signal is acquired. The acquired GPS signal is sent to the processing device 23, and the position information of the rescue tag attachment target 10 is obtained. The GPS receiver 22 is turned off at time t ₃ immediately after the first position information is acquired from the GPS signal. At time t ₃ , the communication device 24 is turned on, and the position information acquired by the processing device 23 is transmitted from the communication device 24. The communication device 24 is turned off at time t ₅ within 5 seconds from time t ₃ . A sleep state is set at a time t ₆ within 10 milliseconds from the time t ₅ , preferably within 5 milliseconds, for example, and this sleep state is continued for 1 second or longer, preferably 1 minute or longer until a time t ₇ . Then, the time from time t ₁ to time t ₆ is set within 10 minutes, preferably within 5 minutes, more preferably within 1 minute, and the operation from time t ₁ to time t ₇ is repeated. These operations are executed according to a predetermined program incorporated in the processing device 23. An example of the time from time t ₁ to time t ₇ is 15 minutes or more and 25 minutes or less, for example, 20 minutes, but the time is not limited to this.

  The position information of the rescue tag wearing target object 10 transmitted from the communication device 24 as described above is transmitted to the relay device 40, and is transmitted from the relay device 40 to the image display device of the search and rescue organization 50. The position information of the rescue tag attachment target 10 may pass through a plurality of relays 40, or may further pass through a telecommunication line (wireless or wired) such as the Internet from the relays 40. Alternatively, the position information of the rescue tag wearing target 10 may be directly transmitted from the communication device 24 to the image display device of the search and rescue organization 50. The position information thus received by the image display device of the search and rescue organization 50 is displayed on the image of the search area displayed on the screen of the image display device. If necessary, it is possible to pay attention to a specific rescue tag attachment target 10 and check the movement trajectory of the rescue tag attachment target 10 within the search area. Preferably, the position of the rescue tag attachment target 10 is shown on the map. Then, the position information of the rescue tag wearing target 10 is transmitted to the search and rescue team 60. The search and rescue corps 60 board a ship, board an aircraft such as a helicopter, or board an automobile.

  In particular, when the target 10 to be attached with the rescue tag is a life jacket, a life buoy, a lifeboat, etc., the rescue tag 20 is attached when the victim with the life jacket is at sea or the rescue tag 20 is attached. When a victim is caught in a life buoy or a lifeboat or is on board, it is first transmitted from the communication device 24 of the rescue tag 20 depending on the weather conditions such as wind direction and wind speed, the direction of the ocean current, the flow velocity, etc. The position of the rescue tag wearing target 10 transmitted to the search / rescue organization 50 via will be displaced. Therefore, in the search and rescue organization 50, the time when the position information transmitted from the communication device 24 of the rescue tag 20 is received by the relay 40 of the ship, the weather information (wind direction, wind speed, etc.) near the disaster site at that time, and The position of the rescue tag attachment target 10 at any time after the time is predicted by computer simulation from the information on the flow of seawater (direction of tide, flow velocity, etc.). Then, the latest position information of the rescue tag wearing target 10 thus predicted is transmitted to the search and rescue team 60. By doing so, it is possible to shorten the time required to search for a victim, and to rescue the victim quickly.

  FIG. 6 shows an example of the overall configuration of the victim search and rescue support system assuming that a victim 70 with a life jacket wearing the rescue tag 20 is drifting over the sea. As shown in FIG. 6, in this example, a quasi-zenith satellite of the quasi-zenith satellite system “Michibiki” is used as the GPS satellite 30. The latitude / longitude information sent from the quasi-zenith satellite is received by the GPS receiver 22 of the rescue tag 20. The reach of radio waves transmitted from the rescue tag 20 attached to the life jacket worn by the victim 70 is indicated by a circle. A search patrol vessel 80 is sailing over the sea, and a search helicopter 90 is flying over the sky. When the patrol boat 80 enters the radio wave range, the latitude and longitude information transmitted from the rescue tag 20 attached to the life jacket attached to the victim 70 is received by the antenna and the receiving terminal mounted on the patrol boat 80. Will be displayed on the display. Similarly, when the helicopter 90 enters the radio wave range, the latitude and longitude information transmitted from the rescue tag 20 attached to the life jacket attached to the victim 70 is received by the antenna and the receiving terminal mounted on the helicopter 90. Received and displayed on the display. In this way, since the position of the life jacket and hence the position of the victim 70 is known, the patrol boat 80 and the helicopter 90 can be rushed to that position, and the victim 70 can be rescued quickly.

  As an example, a specific example of a victim search and rescue support system for performing search and rescue of a victim who has fallen into the sea will be described.

1. In addition to the rescue tag 20, a crew member of the ship attaches a life jacket to which a salt sensor is attached. As will be described later, the rescue tag 20 has a signal transmission confirmation button for confirming that a signal is transmitted from the communication device 23, a transmission button forcibly closing the switch 28, and a survivor being alive. A survival signal button for notifying the user, a speaker for playing a message transmitted to the GPS receiver 22, and the like are connected.
2. When an occupant or the like falls into the sea, the salt sensor attached to the life jacket comes into contact with seawater and senses the salt, and an electric output is generated from the salt sensor. switch 28 is closed, the operation of the time t ₁ ~t ₇ is started. In this way, the GPS receiver 22 acquires position information (latitude / longitude information), and this position information is transmitted from the communication device 24 together with the rescue signal (or rescue signal). A transmission button forcibly closing the switch 28 of the rescue tag 20 is attached to the rescue tag 20 in case the location information or the like is not transmitted from the communication device 24 for some reason. If not, click this send button.
3. The position information or the like transmitted from the communication device 24 is transmitted to a computer (personal computer) or a smartphone on the ship side and notified by a buzzer or the like.
4. The location information of the victim (occupant, etc.) is displayed on the Google map on the display of the computer or smartphone to which the location information is transmitted. The position information displayed on the Google map includes latitude, longitude, crew number, and the like.
5. A message is transmitted to the GPS receiver 22 of the rescue tag 20 that the rescue signal is confirmed from the computer or the smartphone. The message transmission may be, for example, that a rescue signal has been received, that the search vessel is about to rescue, or how many minutes later it will arrive at the scene.
6. When it takes a long time to search for a victim, a safety confirmation message is sent from the search vessel to the GPS receiver 22 of the rescue tag 20, and the speaker confirms the safety.
7. The victim who hears the safety confirmation message presses the survival signal button. When the survival signal button is pressed, a survival signal is sent to the computer or smartphone to inform that the victim is alive.

<Example 1>
A commercially available GPS receiver (corresponding to GPS-125A-077) as the GPS receiver 22 and Arduino Pro of open source hardware as the processing device 23 are provided on a rectangular printed circuit board having a size of about 76 mm × 50 mm as the substrate 21. Mini 3.3V (consumption current about 25mA), commercially available construction design certification acquired as communication device 24 920MHz band LoRa module ES920LR (consumption current about 40mA), and power supply regulators 26 and 27 commercially available output voltage 3.3V regulator NJM2884U1 As the battery 25, a rescue tag 20 equipped with a battery 25 having an output voltage of 4.5 V in which three commercially available AA batteries having a nominal voltage of 1.5 V are connected in series was used. This output voltage of 4.5V was stepped down to 3.3V by NJM2884U1-33. The battery capacity is considered to be about 2000 mAh. The weight of this rescue tag including the protective cover made of plastic is about 110 g, and even if the rescue tag is attached to the life jacket, the weight does not increase so much, and it is considered that the person wearing the life jacket will not be burdened. In the power supply time chart shown in FIG. 5, the power supply was turned on in the cold start state at time t ₁ . The time from t ₁ to t ₂ was several microseconds, the time from t ₂ to t ₃ was 1 to 50 seconds, the measurement was completed at time t ₃ , and the communication device 23 was turned on. Begin transmission time t ₃ after 1 msec, if it can not be the case where can be sent to end the communication within one second after the start of communication, the communication device from time t ₃ to time t ₅ after several milliseconds 24 was turned off. After that, the managed tag enters the sleep state from time t ₆ one microsecond after time t ₅ . At time t ₇ , the power was turned on again. To perform an acceleration test, the time from t ₁ to t ₇ and about 30 to 90 seconds (average about 1 minute), it was repeated the process from t ₁ to t _7.

  The position information was actually acquired by this victim search and rescue support system for the performance confirmation test of this victim search and rescue support system. Specifically, a relay station is installed on the veranda on the third floor of a detached house, and a subject wearing the rescue tag 20 on his / her body can freely walk in a large park having multiple facilities (buildings) near the detached house. I acquired location information until I returned to the detached house again, sometimes around 1 km away from the detached house. As a result, it was possible to obtain the change of the position information with the walking of the subject one after another, and to accurately obtain the movement trajectory.

  From the results of the above acceleration test, it is about 200 days when the position information is acquired and transmitted once an hour until the battery becomes dead and the rescue tag 20 cannot be used. After installing the rescue tag 20 and starting the operation of the rescue tag 20, it is possible to use the rescue tag 20 with three AA batteries for a long period of about 200 days without replacing the battery in the middle. This is extremely surprising considering that conventional general management tags can be used only for a period of less than one month.

<Example 2>
The rescue tag 20 similar to that in Example 1 was used. The rescue tag 20 was housed in a plastic capsule in order to obtain waterproofness, and the capsule was attached to a commercially available life jacket. The power supply time chart of the management tag 120 is the same as that in the first embodiment. However, the time from t ₁ to t ₇ was set to 20 minutes.

  In the sea of Nagasaki Prefecture, I had a diver with the above-mentioned life jacket drop from a ship into the sea. As a result, the rescue tag 20 attached to the life jacket can acquire the diver's position information on the sea in near-time within a practical range, and the effectiveness of the search and rescue support system for victims was verified.

  According to the victim search and rescue support system according to the first embodiment, the following various advantages can be obtained. That is, the position information in the search area can be acquired in a practical range in near time simply by mounting the rescue tag 20 on the rescue tag mounting target 10. Therefore, the position, movement, and the like of the rescue tag wearing target 10 can be grasped within a sufficiently practical range, and the victim or the rescue tag wearing target 10 to which the rescue tag wearing target 10 is mounted is mounted. It is possible to quickly search for a victim who is caught in a lifebuoy, a lifeboat, or boarded, so that rescue can be performed quickly. Further, since the power consumption of the rescue tag 20 can be significantly reduced, even if the battery 25 having a small capacity is used, the rescue tag 20 can be continuously used for a long time, and the battery 25 can be replaced. The frequency can be greatly reduced. Further, since the battery 25 having a small capacity can be used, the weight of the battery 25 can be reduced, and the weight of the rescue tag 20 can be reduced. Therefore, even if the rescue tag 20 is attached to a life jacket, a waist bag, a rucksack or the like worn by a person, or a necklace or the like worn around a person's neck, there is almost no burden and there is no risk of giving unnecessary stress.

<Second Embodiment>
[Remote management system]
FIG. 7 shows the overall configuration of the remote management system according to the second embodiment.

  As shown in FIG. 7, in this remote management system, the management tag 120 is attached to the managed object 110. There is one or more managed objects 110, and when there are multiple managed objects 110, one management tag 120 is attached to each managed object 110. An identification code is given to each management tag 120, and the managed object 110 to which the management tag 120 is attached can be identified by this identification code. The managed object 110 is a living thing represented by livestock such as cattle, various kinds of articles, and the like. The position and method of attaching the management tag 120 to the managed object 110 can be appropriately selected according to the type and property of the managed object 110. For example, when the managed object 110 is a livestock such as a cow, the management tag 120 is preferably attached to a collar fitted on the neck of the livestock, and may be attached separately to the collar or provided integrally with the collar. There may be cases where The management tag 120 is configured similarly to the rescue tag 20. That is, the management tag 120 has a GPS receiver, a processing device (processor), and a communication device, receives GPS signals sent from a plurality of GPS satellites 130 constituting the global positioning satellite system by the GPS receiver, and in the processing device. The position data of the managed object 110 is acquired from this GPS signal, and the position data thus acquired is transmitted to the outside by the communication device. In this way, the position data transmitted from the communication device of the management tag 120 is received by the repeater 140 and recorded in the built-in memory (not shown). One or more repeaters 140 are installed so as to cover the entire management area. Then, the position data recorded in the memory of the repeater 140 is transmitted to the management center 150 wirelessly or by wire and received by the management image display device provided in the management center 150. Then, the image of the management area and the position of the managed object 110 in the management area are displayed on the screen of the image display device. The GPS satellite 130 is most preferably a quasi-zenith satellite of the quasi-zenith satellite system "MICHIBIKI" that can obtain a positioning accuracy of several cm at the maximum, but is not limited to this.

[How to operate the remote management system]
The management tag 120 is attached to one or more managed objects 110 to be remotely managed. For example, when the managed object 110 is a livestock such as a cow, the management tag 120 is attached to a collar or the like fitted around the neck. The method of attaching the management tag 120 is not particularly limited, but for example, the management tag 120 is fixed to the upper part or the lower part of the collar when worn on the neck of livestock by a band or the like. When the managed object 110 is an article, the management tag 120 is attached to the article directly or in a packaging box in which the article is packed. Alternatively, the management tag 120 may be simply put in the packaging box in which the articles are packed.

  The switch 28 is closed and the power of the management tag 120 (main body) is turned on. Thereby, the processing device 23 is turned on and the operation of the remote management system is started. Specifically, the control signal sent from the CTR terminal of the processing device 23 controls the power on / off of the GPS receiver 22 and the communication device 24.

The timing of turning on / off the power supplies of the GPS receiver 22, the processing device 23, and the communication device 24 is as described in the first embodiment (see FIG. 5). For example, when the managed object 110 is a cattle grazing, the time from time t ₁ to time t ₇ is, for example, 25 minutes or more and 35 minutes or less, for example, 30 minutes, but is not limited to this. Absent.

  The position data of the managed object 110 transmitted from the communication device 24 as described above is transmitted to the relay device 140, and is transmitted from the relay device 140 to the image display device of the management center 150. The position data of the managed object 110 may pass through a plurality of relays 140, or may further pass from the relay 140 through a telecommunication line (wireless or wired) such as the Internet. Alternatively, the position data of the managed object 110 may be directly transmitted from the communication device 24 to the image display device of the management center 150. The position data thus received by the image display device of the management center 150 is displayed on the image of the management area displayed on the screen of the image display device. If necessary, a particular managed object 110 can be focused on and the movement trajectory of this managed object 110 within the management area can be investigated. Preferably, the position of the managed object 110 is shown on the map.

  FIG. 8 shows an example of acquiring position data (longitude, latitude) of cows by this remote management system when the above management tags are attached to the collars of 100 cows in a ranch and grazing is performed. In FIG. 8, + marks indicate the position of each cow. FIG. 9 shows an example of tracking the movement locus of one cow selected from 100 cows within a certain time of day. Preferably, the position of the cow is shown on the map.

<Example 3>
The rescue tag 20 used in Example 1 was used as the management tag 120. The weight of the management tag 120 including the plastic protective cover is about 110 g, and the weight does not increase much even if it is attached to the cow's collar. Therefore, even if the collar is attached to the cow's neck, the cow is not considered to be burdened. .. The power supply time chart of the management tag 120 is the same as that in the first embodiment. To perform an acceleration test, the time from t ₁ to t ₇ and about 30 to 90 seconds (average about 1 minute), it was repeated the process from t ₁ to t _7.

  It is considered to be practical enough for users such as ranchers and dairy farmers of this remote management system to be able to acquire position data once every several hours. From the results of the test, the period until the battery runs out and the management tag 120 cannot be used once per hour is calculated to be about 200 days when the position data is acquired and transmitted. Since the management tag 120 can be used for a long time of about 200 days with three AA batteries without having to replace the battery in the middle after the management tag 120 is attached and management is started, It is quite surprising, given that, at best, it can only be used for a period of less than one month.

<Example 4>
The rescue tag 20 used in Example 1 was used as the management tag 120. The power supply time chart of the management tag 120 is the same as that in the first embodiment. However, the time from t ₁ to t ₇ was set to two types, 1 minute (when performing an acceleration test) and 20 minutes.

At a farm in Nemuro City, Hokkaido, this management tag 120 was attached to the collar of 10 cows for grazing, and the position data (longitude, latitude) of the cows was acquired by this remote management system. As a result, the cow position data could be obtained accurately in near time. The time until the management tag 120 becomes unusable due to running out of battery is 3 days if the time from t ₁ to t ₇ is 1 minute, and 60 days if the time from t ₁ to t ₇ is 20 minutes. there were.

  With the remote management system according to the second embodiment, the following various advantages can be obtained. That is, it is possible to acquire the position data in the management area in a practical range in near time simply by mounting the management tag 120 on the managed object 110 to be remotely managed. Therefore, the position and movement of the managed object 110 can be grasped within a sufficiently practical range, and the managed object 110 can be managed well. Further, since the power consumption of the management tag 120 can be significantly reduced, even if the battery 25 having a small capacity is used, the management tag 120 can be continuously used for a long time, and the battery 25 can be replaced. The frequency can be greatly reduced. Further, since the battery 25 having a small capacity can be used, the weight of the battery 25 can be reduced, and the weight of the management tag 120 can be reduced. Therefore, for example, even if the management tag 120 is attached to the collar of livestock such as a cow, the weight of the collar is not increased so that the burden on the livestock is scarce and unnecessary stress is not applied. In addition, if the managed object 110 is a container or the like, there is a case in which it is sufficiently practical to obtain and transmit the position data once a day, for example, and the labor of replacing the battery 25 can be saved for a longer period of time. Therefore, it is possible to contribute to reduction of running cost and labor cost.

  Although the embodiments and examples of the present invention have been specifically described above, the present invention is not limited to the above-described embodiments and examples, and various modifications based on the technical idea of the present invention. Is possible.

  For example, the numerical values, configurations, structures, shapes, etc. mentioned in the above-described embodiments and examples are merely examples, and different numerical values, configurations, structures, shapes, etc. may be used as necessary.

  Further, in the above-described embodiment, the power supply can be turned on / off by the switch 28. However, the switch 28 is omitted and the battery 25, the processing device 23, the communication device 24, and the power supply regulator are omitted. 26 and 27 may be always connected.
