Description

Extension alarm device for a ship and monitoring method

The present invention relates to a communication device for ships, and more particularly, to an extended warning device for ships and a monitoring method thereof.

In a conventional vessel alarm monitoring system, when an abnormality is detected from a sensor mounted on various equipment in a vessel, the status of various equipments captured by a nearby CCTV (Closed Circuit Television) is displayed on the monitor of the upper system. System. After that, the upper system transmits digital and analog output signals to the lower system through the communication relay and through the communication line of the field bus, and the lower system outputs to the drive system of various facilities according to the communication command of the upper system to prepare for abnormal situation. do.

At this time, the CCTV (Closed Circuit Television) system transmits the image information captured by the CCTV camera to a certain number of recipients, and acquires and monitors the information desired by a certain number of users through the transmitted image information. It's a television system that displays images so that you can observe the area.

The CCTV system can store the displayed image according to the use, and the transmission and reception of the image is connected by wire or wireless, and it is called as a closed circuit television because it cannot be arbitrarily received by users other than the recipient.

3 is a functional block diagram of an extended alarm apparatus according to an embodiment of the present invention.

Referring to FIG. 3, the extended alarm device 200 according to the present embodiment includes a communication unit 310, an alarm sound output unit 320, a display unit 330, an input unit 340, and a storage unit 350. .

The communication unit 310 receives alarm information including a location of a specific point when an abnormality occurs at a specific point of the ship, and receives a surveillance camera image from a surveillance camera installed within a predetermined distance from the location of the specific point.

Here, the alarm information is data generated by monitoring an abnormality of the vessel in an alarm monitoring system and generating an abnormality in the vessel. According to this embodiment, the alarm information includes the position of the specific point where the abnormality occurred. For example, if a vessel is divided into three sections, the first region, the second region, and the third region, and if a fire occurs in the second region, the Alarm Monitoring System may identify identification information of the second region, The IP address and the like of the surveillance camera located in the second region can be included in the alarm information.

In addition, the communication unit 310 performs one or more of video communication and voice communication between the extended alarm devices 200. This is to transmit and receive the video and audio packets between the extended alarm device 200 using a wireless LAN network installed in the vessel, a plurality of extended alarm devices 200 of the group communication that participates in one or more of the same video and voice communication You can also communicate in a manner.

When the alarm information is received from the alarm monitoring system, the alarm sound output unit 320 outputs an alarm sound through a speaker. This may warn that an abnormality has occurred in the vessel in the area where the extended alarm device 200 is located.

When an abnormality occurs at a specific point of the ship, the display unit 330 displays the surveillance camera image received from the surveillance camera installed within a predetermined distance from the location of the specific point. In addition, the display unit 330 may display an input menu required for the user to select a specific surveillance camera.

The input unit 340 receives one or more identification information of the surveillance cameras installed within a predetermined distance from the location of the specific point. The identification information of the surveillance camera may be specified by an IP address of the surveillance camera, an identification number assigned to each surveillance camera, and the like. In addition, the input unit 340 may receive a user ID and password from the user in order to allow only the authorized user to access the extended alarm device 200.

The input unit 340 is implemented with a button, a keyboard, a touch panel, and the like. In this case, the touch panel refers to a device capable of contacting a person's hand or an object with a character or a specific position displayed on the screen by an image display device without using a keyboard, and identifying the position and performing specific processing by the stored software. . Therefore, when a character or picture information previously displayed is touched by the extended alarm device equipped with the touch panel by hand, the user selects what is selected according to the position of the screen displayed by the extended alarm device 200 in contact. And the computer can process the corresponding command.

The storage unit 350 may be accessed in a ROM (Read Only Memory), EPIROM (EEPROM: Electrically Erasable and Programmable Read Only Memory), in which unique data, operation programs, and the like are stored, or accessed through a touch panel. It consists of a random access memory (RAM) in which input data is stored.

In the present embodiment, the storage 350 may store the surveillance camera image displayed on the extended alarm device 200 as a record. In this case, the extended alarm device 200 may classify the surveillance camera image based on at least one of the position and the shooting time (date and time) of the surveillance camera and store the image for each folder.

Each step described below is performed by each internal component of the extended alarm device 200, but will be collectively described as the extended alarm device 200 for the convenience of understanding and explanation.

In operation 410, the expansion alarm device 200 receives alarm information including the location of a specific point from the alarm monitoring system 210 when an error occurs at a specific point of the ship. For example, when a fire occurs in the second area, alarm information including identification information specifying the second area is received.

In operation 420, the extended alarm device 200 outputs an alarm sound using an alarm output device such as a speaker. Step 420 is located above the following steps, but does not have to be executed first. That is, the alarm sound output of step 420 may be executed simultaneously with or after any of the following steps.

In operation 430, the extended alarm device 200 receives identification information of one or more of the monitoring cameras 212 installed within a predetermined distance from a location of a specific point. For example, if three surveillance cameras 212 are installed on a vessel, input menu panels for the first, second, and third cameras are displayed, and the user can select one or more of them.

In operation 440, the extended alarm device 200 receives a desired surveillance camera image and displays the image on a screen. When a particular surveillance camera 212 is selected, the surveillance camera 212 transmits the surveillance camera image to the web transmitter 220 via a LAN. Thereafter, the web transmitter 220 converts the surveillance camera image into digital data, and the converted digital image data is received by the extended alarm device 200 through the switching hub 230.

In operation 450, the extended alarm device 200 performs image communication with another extended alarm device 200. In this case, the video communication may be performed in various ways. A plurality of persons in charge may perform a group conference using the group communication of the extended alarm device 200 to suppress the fire.

In addition, the person who receives the surveillance camera image of the area where the fire has occurred can share the received surveillance camera image and discuss fire suppression measures by using the extended alarm device 200 with the person in charge located in another area.

It will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the spirit or scope of the invention as defined in the appended claims. It will be understood that the invention may be varied and varied without departing from the scope of the invention.
