Description

[0002] Disaster forecasting warning systems using satellite communications [

[0001] The present invention relates to a disaster prediction alarm system using satellite communication in a communication field, and more particularly to a system and method for detecting various disasters using satellite communication, that is, GPS (Global Positioning System) And more particularly, to a disaster prediction alarm system using satellite communication for delivering a disaster warning signal to a terminal device.

In recent years, various disasters have occurred frequently due to global warming phenomenon, environmental pollution, and so on. As a result, there is a growing interest in disaster prevention in each country.

In particular, it is spurring research and development on systems that can detect and prevent various disasters such as earthquakes, tsunamis, fires, typhoons, floods, heavy rains or landslides in advance.

The current weather forecasting system that monitors abnormal weather forecasts forecasts for a wide range of areas through meteorological satellites, while detailed weather information is not delivered to local places such as mountain valleys and riverside amusement parks. In reality, Remains.

For example, when a disaster such as a mountainous valley landslide occurs, the management office receives a primary weather report from the central control agency and delivers it again, so it can not prepare for floods occurring within a short time.

As part of such disaster prevention systems, the conventional disaster alarm system is a system in which disaster alert systems such as the central government or the local government disaster prevention agencies are operated by various disaster observation stations observing rainfall, snowfall, earthquake, wind speed or landslide And the results were used to judge the likelihood of a disaster, the occurrence of a disaster, and the extent of the disaster, and then alarmed through media such as newspapers and broadcasts.

However, due to the fact that the person visited the expected spot of the disaster and confirmed it by using the equipment that detects the various disaster factors at the spot, it is possible to identify the disaster factors only in some places where disaster is expected due to budget and manpower shortage. It is impossible to precisely detect minute changes such as terrain that predicts a disaster, and thus it has been difficult to prevent disasters in advance.

Korean Patent Registration No. 10-0589662 (2006.06.07), "Disaster warning system and method using GPS" has been disclosed as a prior art that partially alleviates such a problem.

The disclosed system and method measures a relative position of a specific position relative to a preset reference position in real time using a GPS receiver, calculates a displacement of the specific position using the measured coordinates, It is determined that a disaster will occur and a disaster alarm message is transmitted from the disaster planning coordinates to a terminal within a predetermined radius, thereby accurately estimating a disaster occurrence location using GPS and promptly delivering a disaster alert to the residents.

However, in the case of the registered patent, since the image acquiring unit is fixed and fixed so as to face only a specific point, there arises a problem that when the interferer appears around the image acquiring unit according to the environmental change, the desired imaging point can not be accurately photographed.

If such a phenomenon occurs, accurate imaging is difficult, and accurate and sufficient disaster forecasting can not be made in case of an emergency. Therefore, it is possible to cause an unexpected human accident as well as a facility accident or natural disaster when a disaster occurs.

In other words, if forecasts were possible, you would have missed all of the talents that could have been prevented, resulting in a big loss.

However, it should be understood that the embodiments according to the concept of the present invention are not intended to limit the present invention to specific modes of operation, but include all modifications, equivalents and alternatives falling within the spirit and scope of the present invention.

In the following description, a plurality means at least one.

The present invention includes the structure of the above-mentioned Japanese Patent No. 0589662 as it is and improves the structure of the image acquiring unit 13 (refer to Fig. 1) to enable rapid and accurate peripheral photographing without being constrained by the interferer. . Therefore, the configurations of Figs. 1 to 5, which will be described below, refer to the content of the above-mentioned registered patent as it is.

1, a disaster warning system using satellite communication (hereinafter referred to as GPS) is fixedly installed at a specific location P where a disaster is expected to occur, and is transmitted from a GPS satellite 11 A position measuring unit 12 for receiving the GPS signal from the position measuring unit 12 and measuring and transmitting relative coordinates of the specific position P with respect to a preset reference position P0 in real time, A displacement calculator 14 for calculating a displacement of the specific position P in real time by using the coordinates of the specific position P to be compared with the predetermined displacement P, The comparison unit 15 compares the calculated displacement with the predetermined threshold to determine whether the position of the corresponding terminal among the plurality of all terminals 40 registered in the predetermined position P is within a predetermined radius, (42) A message generating unit 17 for generating a disaster alert message suitable for the detected first terminal 42 and the emergency alert message through a predetermined communication network 30 to the detected first terminal 42 (Not shown).

Further, the present invention may further include an image acquisition unit 13 for acquiring and transmitting a peripheral image of the specific position P in real time, and a display unit 19 for displaying the obtained peripheral image.

The reference point receiver 10 is a device for receiving GPS satellite signals transmitted from the GPS satellites 11 and sets a reference position with respect to the position coordinates of the position measurement unit 12. [

Also, the second terminal 41 indicates a terminal not within the predetermined radius range among the all registered terminals 40 previously registered.

Further, the database 20 stores registration information of all the registered terminals 40 and information on users of each terminal.

The position measuring unit 12 may be fixed at a position P where a disaster such as a landslide, a heavy snowfall, heavy rains, a tsunami, or an earthquake is expected.

Preferably the ground surface can be located on a sloping slope.

The position measuring unit 12 receives the GPS satellite signal transmitted from the GPS satellite 11 and measures the relative position with respect to the reference position P0 of the reference point receiver 10 and outputs it as coordinates.

Preferably, the position measuring unit 12 is a GPS receiver.

The position coordinates may be, for example, three-dimensional coordinates that are (x, y, z) coordinates displayed in two dimensions or space, which are (x, y) coordinates displayed on a plane.

The reference point receiver 10 is fixedly disposed on a stable ground while maintaining a proper distance from the position measuring unit 12. [

The reference point receiver 10 and the position measuring unit 12 each include a wireless modem for mutual communication.

Although only one of the position measuring units 12 is shown in the figure, in another embodiment, more than two position measuring units 12 may be provided depending on the area or size of a place where a disaster occurs.

The position measuring unit 12 transmits the coordinate data of the specific position P measured as described above to the displacement calculator 14 through various communication paths.

Preferably, an RS-422 communication path can be used.

Meanwhile, the reference point receiver 10 also transmits data information including coordinates of the reference point position P0 to the displacement meter section 14 through various communication paths.

Preferably, TCP / IP can be used.

The displacement calculator 14 calculates the displacement of the specific position P at which the position measuring unit 12 is installed using the data transmitted from the position measuring unit 12 and the reference point receiver 10.

More specifically, the displacement calculator 14 receives the coordinate data of the specific position P transmitted in real time from the position measuring unit 12, and outputs the coordinate data of the specific position P, And calculates how much the specific position P has moved.

For example, assuming that the coordinates of the specific position P at which the position measurement unit 12 is initially set are (X, Y, Z) (assuming three dimensions) as a position relative to the reference position P0, If the specific position P changes to (x, y, z) relative to the reference position P0 due to a disaster such as an earthquake or a landslide, the displacement displacement data of the specific position P is Is obtained by the following equation (1).

[Formula 1]

Moving Displacement =

The comparator 15 compares the measured displacement of the specific position P with a preset threshold value.

That is, the comparing unit 15 compares the predetermined position with a predetermined threshold value to determine the degree to which the displacement of the specific position P has moved.

Here, the threshold value of the present invention is a value for determining whether a disaster occurs at the specific position P or not.

That is, if the displacement of the specific position P exceeds the threshold value, it means that the specific position P has changed much due to an earthquake, a landslide, or the like, and it is determined that the possibility of a disaster is very high.

The terminal detector 16 determines that a disaster is likely to occur when the computed displacement of the specific location P is greater than the preset threshold value and searches the DB 20 for a plurality of all registered terminals 40 Of the first terminal 42 existing within a certain radius from the specific position P where the disaster is expected to occur.

The terminal detection unit 15 of the present invention will be described in more detail.

FIG. 2 is a schematic block diagram showing the operation of the terminal detection unit 16 according to the present invention.

2, the terminal detection unit 16 of the present invention includes a coordinate request unit 161 for requesting the position coordinates of the corresponding terminal 40 to all the registered terminals 40, And a coordinate receiving unit 162 for receiving the position coordinates.

The coordinate request unit 161 requests the entire terminal 40 for the coordinates of the corresponding terminal 40 using the information data of the entire terminal 40 registered in the DB 20. [

The entire terminal 40 includes a GPS chip 401 and a coordinate measuring unit 402 and receives a GPS signal from a GPS satellite and measures coordinates of the GPS receiver 401 at a predetermined period.

The terminal 40 transmits its positional coordinate to the coordinate receiving unit 162 in response to the coordinate request of the coordinate requesting unit 161 of the terminal detecting unit 16.

Accordingly, the terminal detector 16 grasps the respective position coordinates of all the terminals 40 registered in the DB 20, and detects the position of the first terminal P existing within a predetermined radius from the specific position P, The terminal 42 is detected.

Referring again to FIG. 1, the message preparation unit 17 prepares a disaster alert message associated with each of the detected terminals 42.

That is, the message preparation unit 17 implements a disaster alert message so as to be suitable for transmission to each terminal 40 using the DB 20 in which the approval data for each terminal 42 is stored.

For example, the entire terminal 40 may be an Internet, a mobile phone, a PDA (personal digital assistant), or the like. More specifically, if the terminal is a mobile phone, the entire terminal 40 may be written as a text message.

The generated emergency alert message is transmitted to each of the first terminals 42 via the predetermined communication network 30 by the transmitter 18.

The message transmission may be implemented using a Unified Messaging System (UMS) or a Location Based Service (LBS) system.

However, message transmission using such a system is merely an embodiment of the present invention, and a technique such as SMS (Short Message Service) may be used.

For example, the transmission of alert messages can be implemented in various forms, such as voice, fax, and e-mail, using a public switched telephone network (PSTN).

These various types of messages can be integrated in a single mail box, and can be accessed through various communication media such as PCs, telephones, faxes, mobile phones, and the like.

In addition, personal messages can be checked at any time and place, managed over the Internet, and can be faxed using fax conversion technology using e-mail systems, And can be delivered to the recipient via voice mail and voice mail.

In this way, the alert message can be transmitted over various communication networks 30.

The entire terminal 40 may be a computer connected to the Internet, a general telephone connected to a wired / wireless communication network, a cellular phone, or an automatic call sender (ACS) system.

In an embodiment of the present invention, the emergency alarm system of the present invention includes a display unit 19 for displaying the displacement displacement data of the specific position P calculated by the displacement calculator 14, And an image acquisition unit 13 for acquiring and transmitting an image for a predetermined area around the image pickup device.

The displacement calculator 14 calculates the displacement of the specific position P using the position coordinate value of the specific position P transmitted in real time from the position measuring unit 12 and outputs it to the display unit 19 ).

At this time, the display unit 19 may display the surrounding image of the specific position P transmitted by the image obtaining unit 13 together or separately.

The image acquiring unit 13 is an apparatus for acquiring a peripheral view of a specific position P provided with at least one position measuring unit 12 as an image or an image and captures an image of the object within a certain area.

Although not shown in the drawing, a control unit (not shown) may be provided for controlling the overall operation of the image acquiring unit 13 and adjusting the range and angle of an image to be photographed.

Here, the image acquiring unit 13 may be an apparatus capable of photographing an image.

More preferably, it is, for example, an infrared camera or a CCD camera, but is not limited thereto.

3 is a diagram showing an image and moving displacement data at a specific position displayed on the display unit according to an embodiment of the present invention.

3, the displacement displacement data of the specific position P calculated by the displacement measurement section 14 and the image of the periphery of the specific position P acquired by the image acquisition section 13 are displayed on the display section 19, Lt; / RTI >

In FIG. 3, displacement data according to the amount of rainfall is displayed as one embodiment, and a surrounding image for a specific position P is displayed.

3A is an image for the reference point receiver 10 installed at the reference position P photographed by the image obtaining section 13 and at least one position measuring section 12 provided at the specific position P. FIG.

3 (b) is a graph showing movement displacement data of a specific position according to the amount of rainfall.

Meanwhile, in another embodiment of the present invention, image and moving displacement data for the specific position P may be displayed through a geographic information system (GIS).

The Geographic Information System (GIS) allows users to receive results in the form of maps of any kind through query or analysis of relational databases.

Because many types of data have important geographical features, GIS is used in diverse areas such as weather forecasting, sales analysis, population forecasting and land use planning.

In GIS, geographical information is clearly depicted in the form of geographical coordinates (such as latitude and longitude or lattice coordinates of a country), or in an implicit form such as street address, zip code, and location of the forest.

4 is an exemplary view of a disaster alert message through a mobile phone according to an embodiment of the present invention.

As described above, when the displacement of the specific position P calculated by the displacement measurement section 14 is larger than a preset threshold value, disaster occurrence is expected, so that the terminal detection section 16 detects a constant Detects a first terminal (42) existing within a radius of the first terminal (42), and the message preparation unit (17) creates a disaster alarm message suitable for each detected first terminal (42).

FIG. 4 illustrates an example of transmitting a disaster alert message to be transmitted to a mobile phone widely used by the general public according to an embodiment of the present invention.

At this time, the mobile phone has previously been approved and related information for transmission is stored in the DB 20 in advance.

Accordingly, the message creating unit 17 can create a disaster alert message suitable for the mobile phone using the mobile phone related information stored in the DB 20. [

The generated emergency alert message is transmitted to the mobile phone by the transmitter 18, and a disaster alert message is displayed on the display window of the mobile phone as shown in FIG.

5 is a flowchart illustrating an emergency alert method implemented in the GPS emergency alert system of the present invention.

Referring to FIG. 5, after various GPS receivers are initialized (S400), reference point coordinates are set from the reference point receiver 10 (S402), and GPS satellite signals transmitted from the GPS satellites are received And measures the relative coordinates of the specific position P with respect to the coordinates of the preset reference position P0 in real time (S404).

At this time, the coordinates may be two-dimensional or three-dimensional coordinates.

The displacement of the specific position P with respect to the reference position P0 is calculated using the coordinates of the specific position P (S406).

The displacement can be calculated for each of X, Y (or X, Y, Z) directions.

Next, it is determined whether the calculated displacement of the specific position P is greater than a preset threshold (S408).

If the displacement of the specific position P is not greater than the threshold value, the coordinates of the specific position P are continuously measured (S404). If the displacement is larger than the threshold value, The first terminal 42 existing within a predetermined radius from the coordinates of the specific position P among the entire registered terminals 40 is detected at step S410.

That is, since there is a disaster risk within a certain radius from the coordinates of the specific position P, the entire terminal 40 stored in the DB 20 to notify the user of the first terminal 42 within the radius, And detects the position of the first terminal 42 within the radius.

Next, a disaster alarm message to be transmitted to each of the first terminals 42 is generated (S412).

The disaster alert message is prepared to be suitable for transmission to the detected first terminals 42. The approval data for each first terminal 42 is stored in advance in the DB 20. [

The generated emergency alert message is transmitted to each of the first terminals 42 (S414).

The message transmission may be implemented using an UMS or LBS system.

Here, the displacement displacement data of the specific position P calculated in the step S406 can be displayed on the predetermined display unit 19. [

An image of the periphery of the specific position P may be acquired and displayed on the display unit 14 together with or separately from the movement displacement data.

The display unit 14 may be implemented as an LCD or other display.

Thereby, the manager can directly visually confirm the movement state and the movement displacement of the specific position (P) through the screen of the display section (14).

6 and 7, the position of the image acquiring unit 13 is configured to be variable so that even if an interferer appears due to an environmental change, the present invention avoids this, And can be configured to be capable of transmission.

At this time, the image acquiring unit 13 may be mainly a camera, especially a vision camera.

For example, referring to FIGS. 6 and 7, a 'U' shaped pedestal 510 having an open top is fixed to a mounting surface 500 on which the image acquiring unit 13 is installed.

The pedestal 510 is hollow and the stepped pedestal 512 is formed on the opened top surface in the circumferential direction.

The stepped surface of the stepped surface 512 is formed to be inwardly lowered, and has a stepped shape.

A plurality of lower ball grooves 514 are formed in the stepped surface 512 so as to be spaced apart in the circumferential direction.

The rotation base 520 is mounted on the stepped surface 512. The rotation base 520 is formed in a disk shape and has an upper ball groove 524 corresponding to the lower ball groove 514 ) Are formed at a plurality of intervals.

At this time, the upper ball groove 524 is recessed in a direction opposite to the lower ball groove 514.

A cloud ball 530 is inserted between the upper ball groove 524 and the lower ball groove 514.

Therefore, the rotating base 520 can be smoothly rotated on the upper surface of the pedestal 510.

A driven shaft 540 protrudes from the center of the lower end surface of the rotating base 520 and a driven gear 542 is integrally formed with the driven shaft 540.

A drive gear 552 is coupled to the driven gear 542 and a drive shaft 550 protrudes from the center of the drive gear 552. The drive shaft 550 is connected to the rotation axis of the drive motor 560, In other words, it is connected to the motor shaft.

At this time, the driving motor 560 is fixed on the inner bottom surface of the pedestal 510.

Therefore, when the drive motor 560 rotates, the drive gear 552 rotates to rotate the driven gear 542, so that the rotation base 520, which is integrally formed with the driven shaft 540, As a rotation center.

Here, the drive motor 560 is a step motor that reciprocally rotates within a certain angle, and the drive gear 552 and the driven gear 542 are spur gears.

7, a pair of rotation guide holes 570 having a substantially semicircular shape in the circumferential direction are formed on the rotation base 520, and guide rods 580 are inserted into the rotation guide holes 570 Loses.

The upper end of the guide rod 580 is partially exposed through the rotation guide hole 570 and the lower end thereof is integrally fixed to the bottom surface of the pedestal 510.

Accordingly, even if the rotation base 520 rotates and reciprocates, the guide rod 580 is guided while being inserted into the rotation guide hole 570, so that the rotation base 520 is smoothly rotated Thereby making it possible to reciprocate.

Further, a fixing bracket 590 is fixed to one side of the upper surface of the rotating base 520, and one end of the flow guide 592 is fixed to the fixing bracket 590.

In this case, one end of the flow guide 592 is integrally fixed to the fixing bracket 590 and extends in a arc shape, and has an arc-shaped guide hole 594, .

A tightening knob 596 is fastened to one side of the image acquiring unit 13 so that the tightening knob 596 is tightened through the guide hole 594 and can not pass through the guide hole 594. [ And has a hooked head.

That is, the head of the tightening knob 596 has a larger diameter than the guide hole 594.

A shaft 610 is fixed to the rear end of the image acquiring unit 13 and the shaft 610 is fixed to the shaft bracket 620. A rotary motor 630 is fixed to the shaft bracket 620, The motor shaft of the rotation motor 630 is connected and fixed to the shaft 610.

Accordingly, when the rotation motor 630 rotates, the shaft 610 rotates so that the image acquiring unit 13 can rotate with a certain radius with respect to the shaft bracket 620 with the shaft 610 as a rotational center .

At this time, since the tightening knob 596 is hooked on the guide hole 594, the image acquiring unit 13 is rotated along the flow guide 592.

Therefore, the image can be stably rotated, the angle of photographing of the image acquiring unit 13 can be adjusted, and multi-directional photographing is possible, and even if an interferer appears, it can be avoided and captured.

Particularly, it is more preferable that the rotation motor 630 is further provided with an encoder to finely adjust the rotation angle. For this purpose, a controller C may further be provided on the image acquisition unit 13.

The shaft bracket 620 is firmly fixed to the bent end portion 602 through the bolt B and the bent end portion 602 is bent at the upper end of the vertical post 600, Is firmly fixed to the upper surface of the rotating base 520.

Consequently, the image acquiring unit 13 can rotate and adjust the angle so that the photographing range becomes as wide as that, and the avoidance photographing is easy even when the interferer appears.

For example, when the image pickup section 13 is in front of the image pickup section 13, the controller C rotates the drive motor 560 for image pickup.

Then, the rotary base 520 is rotated and moved to a position where it can be taken out of the area covered with the grass.

When the position is fixed in this state, the rotation motor 630 operates to precisely adjust the imaging angle.

After the adjustment is completed in this manner, the image capturing is started and the captured information is transmitted.

Therefore, even if an interferer appears, it is possible to take an avoidance picture and to perform an effective disaster prevention function.

In some cases, if the ball 510 is deformed by using a ball screw or by using a cylinder so as to raise and lower the pedestal 510 itself, it is expected that it will have a more perfect shooting function.
