BEST MODE FOR CARRYING OUT THE INVENTION The present invention will be described in more detail with reference to the drawings.

1 and 2, a marine situation monitoring apparatus 100 according to the present invention includes a main body 110 installed on a ship 10 and fixed to the main body 110 And a binding cable 130 for connecting the flotation device 120 and the main body 110 to each other. Basically, the floating apparatus 120 is fixed to the main body 110 or the ship 10 before the 'unfolding event' occurs, and when the 'unfolding event' occurs, the floating apparatus 120 is separated from the main body 110, And then performs various monitoring operations. Here, the unfolding event is an event that the floating device 120 is separated from the main body 110 and deployed in the air, and can be generated under various conditions by the M-control unit 116 as described below.

The floating device 120 and the main body 110 are interconnected through the binding cable 130 even in the state of being deployed in the air. The binding cable 130 is used to bundle the floating device 120 within a predetermined distance from the main body 110 and to recover the floating device 120 that has completed the monitoring operation to the vessel 10. The maximum flotation height of the flotation device 120 depends on the overall length of the binding cable 130 and is typically from a few tens of meters to several hundred meters and even up to several kilometers. The tensile strength of the binding cable 130, the weight of the lifting device 120, and the like can be factors that determine the maximum lifting height of the lifting device 120.

2, the floating device 120 includes a camera unit 121, a measurement unit 122, an S-communication unit 123, a buoyancy module 124, a propulsion module 125, and an S- The main body 110 includes a floating device expanding section 111, a power supply section 112, a device recovery section 113, an M-communication section 114, a sensor section 115 and an M- .

&Lt; Configuration of floating device > 00

First, the configuration of the floating device 120 will be described. The camera unit 121 of the floating apparatus 120 includes at least one camera 121-1 to perform a monitoring operation to generate an image (including a moving image) photographed in the surroundings. Preferably, the camera of the camera unit 121 is provided in a rotatable or rotary type, or a plurality of cameras are provided in each of the camera units 121 so as to observe different directions. An Infra-Red camera may be provided for shooting at night.

The measuring unit 122 may be equipped with various sensors or measuring means necessary for monitoring the surrounding conditions (wind speed, GPS position information, illuminance, etc.) to measure wind speed, illuminance, etc., or receive GPS signals.

The S-communication unit 123 is a wired and / or network interface that can be connected to a wired and / or wireless network. In the case of a wired protocol, a wired LAN (LAN) and various other wired communication protocols known in the art are possible. In the case of a wireless protocol, any conventional wireless protocol such as a wireless LAN, a mobile communication network, a satellite communication network, and various broadcasting communication networks can be used and a plurality of wireless protocols can be held. When a wired interface is used for communication with the M-communication unit 114 of the main body 110, a method of wiring a communication line (not shown) together with the binding cable 130 can be used. Although the transmission and reception of data is described below as if the transmission and reception of data are performed directly between the S-control unit 127 and the M-control unit 116 or between the S-control unit 127 and the external terminal (not shown) Should be understood as mediated.

The buoyancy module 124 generates buoyancy to float the flotation device 120 into the air and maintains the basic buoyancy, and operates when the flotation device 120 is deployed in the air due to the development event. The manner in which buoyancy module 124 generates buoyancy is possible in any manner known in the art. For example, as in Figures 1 and 2, the buoyancy module 124 has an air bag 124-1 that receives gas to create buoyancy. The airbag 124-1 may be maintained in a gas filled state in advance, or may supply gas in the floating device deployment section 111 in accordance with the deployment event.

The buoyancy module 124 may reduce the amount of gas injected into the airbag 124-1 in order to reduce buoyancy or reduce the buoyancy if necessary, Can be removed.

The propulsion module 125 is not an essential configuration of the present invention. However, it must be provided for the position / attitude control necessary for the monitoring operation of the floating device 120 of the present invention. Basically, a certain wind speed is blown in the air, and since the binding cable 130 is not a rigid body having a constant shape, the buoyancy module 124 alone can not control the position of the float device 120. Therefore, it is indispensable when the floating apparatus 120 wants to photograph a specific place or when it is intended to provide an emergency survivor with an emergency survivor.

The actual configuration of the propulsion module 125 may also be any conventionally known method used for position control of airborne vehicles. For example, the propeller would be an example of a basic propulsion module 125.

The S-control unit 127 controls the overall operation of the flotation apparatus 120 and includes a monitoring control unit 128 and a posture control unit 129 for this purpose.

The monitoring control unit 128 performs a monitoring operation according to a preset algorithm or an external control command using the camera unit 121 and the measurement unit 122. [ The posture control unit 129 performs posture control using the propulsion module 125 according to a preset algorithm or an external control command.

Hereinafter, the configuration of the main body 110 will be described. 1 and 2 show the main body 110 as a separate device fixed to the ship 10, but the present invention is not limited thereto. For example, the main body 110 may be installed in a device that is basically provided for operating the ship 10, or the main body 110 may include a sensor unit 115, an M-communication unit 114, The same configuration may be used in common.

The floating device expanding unit 111 unlocks the floating device 120 according to the expansion event and expands it into the air.

The floating device 120 is fixed to the main body 110 or the locking device 111-1 provided at one side of the ship 10 before the unfolding event occurs. The locking device 111-1 is not necessarily provided in the main body 110 and may be provided at one side of the ship 10, 111). The floating device deploying unit 111 unlocks the locking device 111-1 at the time of the deployment event and expands the floating device 120 into the air.

In the embodiment in which the buoyancy module 124 includes the airbag 124-1, the floating device deployment portion 111 may have a gas supply portion 111-2 that supplies gas to the airbag 124-1, And causes the gas supply unit 111-2 to supply gas to the airbag 124-1 in accordance with the deployment event. The flotation device 120 is deployed in the air while the release of the locking device 111-1 is completed and the floating device 120 deployed in the air develops a constant It floats up to the height.

The power supply unit 112 is connected to the floating unit 120 through a power cable 112-1 to supply power to the floating unit 120. [ The power cable 112-1 can be wired together with the binding cable 130.

The device recovery unit 113 winds the binding cable 130 according to the 'recovery event' to recover the floating device 120 to the main body 110 or the ship 10. Here, the recovery event is an event for recovering the floating device 120 deployed in the air to the ship 10, and is generated by the M-control unit 116.

The M-communication unit 114 is a wired and / or network interface that can be connected to a wired and / or wireless network and is basically provided for communication with the S-communication unit 123 and the external terminal (not shown) do. Here, the external terminal may correspond to the main communication means of the ship 10 or the like. It should be understood that the M-communication unit 114 is mediated even if data transmission / reception is described as being performed directly between the S-control unit 127 and the M-control unit 116 in the following description.

The sensor unit 115 is for confirming the generation condition of the development event, and corresponds to a pressure sensor and a tilt sensor for determining whether the ship 10 is in an emergency such as rollover. The pressure sensor is provided on one side of the vessel 10 or the main body 110 to measure the pressure. The inclination sensor measures the attitude or inclination of the ship 10 or the main body 110 by a combination of a geomagnetic sensor or the like.

The M-control unit 116 controls the overall operation of the main body 110 of the present invention by controlling the floating unit expansion unit 111, the power supply unit 112, the M-communication unit 114, the device recovery unit 113, Lt; / RTI > (3) monitoring the power supply of the power supply unit 112, (3) starting / stopping the power supply unit 112, (4) Operation start / stop / monitoring of the device recovery unit 113 are included in these basic operations.

In particular, the M-control unit 116 includes an event processing unit 117 to generate and execute the deployment event and the collection event of the present invention. Basically, the development event has a development event according to a user's request and an 'development event according to an emergency situation'.

The deployment event according to the emergency situation is automatically performed in an emergency such as the overturning of the ship 10 and will be described below with reference to FIGS. Explains how to automatically perform deployment events.

[Processing of deployment event according to an emergency situation: Fig. 3]

The floating device 120 in a state where there is no deployment event is fixed to the main body 110 or the ship 10 by the lock device 111-1. The buoyancy module 124 of the flotation device 120 does not need to generate and maintain buoyancy in advance so that the airbag 124-1 of the buoyancy module 124 of Fig. 2 will remain unfilled with the gas. However, it is possible to always maintain a constant buoyancy in accordance with the embodiment of the buoyancy module (124).

The binding cable 130 may be held in a state that it is not fixed to another apparatus, but may be wound on a bobbin (not shown) or the like by the apparatus recovery unit 113.

&Lt; Determination of condition for development event and generation of development event: S303, S305 >

3 is generated in the emergency situation of the ship 10. [ For this, the event processing unit 117 determines the condition using the measured value of the sensor unit 115. [ As described above, the sensor unit 115 may use a pressure sensor, a tilt sensor, or the like, and the event processing unit 117 may measure the sensor unit 115 measurement value (or a change in the measurement value thereof) ) As a development event generation condition.

For example, in the case of a tilt sensor (not shown), (1) the measured value is equal to or greater than the first reference value (or less), (2) the measured value is not equal to or greater than the first reference value, It can be judged as an emergency situation such as overturning. Therefore, it is possible to set more than or equal to the first reference value (or less), a pattern of the change amount, and the like as a developing event condition.

Or in the case of a pressure sensor, it may be attached to one side of the ship 10 to judge an emergency situation by setting the pressure or the pressure change when a large wave or the like is covered as a predetermined condition.

The event processing unit 117 continuously monitors whether the predetermined condition is met while monitoring the measured value of the sensor unit 115 in step S303, and generates an event in step S305 when the predetermined condition is satisfied.

&Lt; Buoyancy module of floating device generates buoyancy: S307 >

When the expansion event is generated in step S305, the event processing unit 117 causes the buoyancy module 124 of the floating device 120 to generate buoyancy. 2, if the buoyancy module 124 has the airbag 124-1, the event processing unit 117 controls the floating device deployment unit 111 to supply the gas to the airbag 124-1 And the gas supply unit 111-2 of the floating device deployment unit 111 supplies gas to the airbag 124-1. As the gas is supplied to the airbag 124-1 at a constant pressure, the floating device 120 is buoyant.

When the air bag 124-1 is filled with the gas at a predetermined pressure to generate the buoyant force, the event processing unit 117 controls the floating device expanding unit 111 to float the floating device 120 into the air. Accordingly, the floating device deploying unit 111 unlocks the locking device 111-1 to allow the floating device 120 to float in the air.

At this time, if the binding cable 130 is wound around the bobbin (not shown) by the device recovery unit 113, the event processing unit 117 controls the device recovery unit 113 to release the bobbin locker, So that the cable 130 is lifted up along the lifting device 120.

Since the deployment event according to the emergency situation is not processed by the user as needed, the monitoring operation to be performed in the air by the floating device 120 must be set in advance.

When the floating device 120 floats in the air, the event processing unit 117 controls the posture control unit 129 of the S-control unit 127 to perform posture control for performing an operation according to a predetermined monitoring algorithm . Accordingly, the posture controller 129 controls the propulsion module 125 to perform posture control according to a predetermined algorithm.

According to the embodiment, instead of the posture control unit 129 receiving the specific posture control algorithm from the event processing unit 117 after the deployment event, the event processing unit 117 notifies the S-control unit 127 that the current state is an emergency state The posture controller 129 may automatically perform a predetermined posture control algorithm for the deployment event according to the emergency situation.

The predetermined algorithm may be a posture in which the coordinates of the main body 110 provided by the event processing unit 117 are rotated along a circular locus having a predetermined distance as a center point. Therefore, when the trajectory deviates from the original trajectory by the wind at the altitude where the flotation apparatus 120 is located, the posture control unit 129 controls the propulsion module 125 to return to the original trajectory.

The S-control unit 127 controls the camera unit 121 and the measurement unit 122 to perform a predetermined monitoring operation on the deployment event according to the emergency situation. The S-control unit 127 performs a monitoring operation to provide a value measured by the measurement unit 122 and an image generated by the camera unit 121 to the M-control unit 116 of the main body 110 or an external terminal .

In accordance with the above-described method, a generation method and a processing method according to an emerging event according to the emergency situation of the present invention are performed. (1) receiving a control command from a user in place of steps S303 to S305 to generate a development event, and (2) expanding S311 and S313 Only in that it performs the requested operation via the control command in the step.

On the other hand, the recovery event is basically performed when the user's control command exists, such as when the emergency situation is canceled or when the user's needs are satisfied.

In the case of the recovery event, the event processing unit 117 controls the device recovery unit 113 to wrap the binding cable 130 in the bobbin to recover the flotation apparatus 120. At this time, the event processing unit 117 may notify the S-control unit 127 of the recovery event so that the propulsion module 125 and the buoyancy module 124 can control to perform operations necessary for the recovery of the floating device 120. [ The recovery device 120 can be controlled to be located directly above the ship 10, so that the recovery operation of the device recovery unit 113 can be performed smoothly.

According to an embodiment, the buoyancy module 124 may further include a tongue (not shown) for slidably supporting the floating device 120 in the air. In this case, the propulsion module 125 of FIG. 2 may not be provided.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is clearly understood that the same is by way of illustration and example only and is not to be construed as limiting the scope of the invention as defined by the appended claims. It will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the present invention.
