Hereinafter, preferred embodiments of the present invention will be described with reference to the accompanying drawings. Although the present invention has been described with reference to the embodiments shown in the drawings, this is described as one embodiment, whereby the technical spirit of the present invention and its core configuration and operation are not limited.

1 is a schematic perspective view showing a state in which the joint ball monitoring apparatus according to the present invention is installed in the cavity ball.

The joint ball monitoring device according to the present invention is made of underground, such as power lines, water pipes, sewer pipes, heating and cooling pipes, gas pipes, communication lines, power lines, oil pipelines, etc., which are arranged in the cavity 10 installed underground. As shown in the figure, a device for enabling real-time monitoring of the state of), the rail 11 is installed on one side of the cavity 9 in the longitudinal direction of the cavity 9, along the rail 11 It comprises a camera 12 for taking an image while moving, and a sensor 13 installed in the underground buried ship 20 is installed in the hollow ball (10). Reference numeral 15 in the drawing is an antenna 13 for transmitting a signal from the sensor 13.

Specifically, the rail 11 is installed in one side wall or one ceiling of the cavity 20 in the longitudinal direction (the longitudinal direction) of the cavity 10. The camera 12 which captures an image captures the inside of the cavity 10 while moving along the rail 11 to acquire an image. The camera 12 has a function of transmitting the acquired image to the outside of the cavity 9 as described later.

Since the cavity 10 is long in the longitudinal direction but the width is narrow, when the camera is installed in the section of the cavity 9 that needs to be monitored, a large restriction is placed on the area that each camera can shoot. Although the cameras may be densely installed at narrow intervals in order to expand the shooting area, in this case, the cost of installing the camera becomes excessive, so that it cannot be practically applied. In the present invention, since the rail 11 is installed as described above and the camera 12 moves along the rail 11 to acquire an image of the inside of the cavity 10, the entire interior of the cavity is monitored without restriction of the imageable area. While there is no increase in the number of installations of the camera, the effect of being able to economically monitor the common tool 10 is exerted.

In the present invention, as the camera 12, various types of cameras, such as CCTV cameras or web cameras, which are commonly used, can be used without particular limitations. It is desirable to use a camera that can zoom in and out of the scene, because it can be a great help in responding properly to accidents in the common sphere.

2 and 3 show an embodiment of the configuration in which the camera 12 can move along the rail 11 in a perspective view. As shown in FIG. 2, the rails 11 have wheel moving parts on both sides. It is formed to have an I-shaped cross section 110 is formed concave, rolling wheels 111 to move along the wheel moving portion 110 and the connecting frame 112 connecting the both wheels 111 Mounting the camera 12 to the camera mounting portion made, it can be configured to move the camera 12 along the rail 11 by the wheel 111. In addition, as shown in FIG. 3, the rail 11 is formed of a lumber, and an opening 113 having a long slot shape is formed on a lower surface of the ridge, and the wheel 111 is disposed on the shaft 120 of the camera 12. Is installed perpendicular to the shaft 120, the shaft 120 is inserted into the opening 113, the wheel 111 is across the lower surface of the rail material on both sides of the opening 113 and the side surface of the rail material of the rail (11) The camera 12 can be attached to the rail 11 in the state which made cloud movement possible. The wire 120 is wound around the shaft 120, and as the wheel 111 rolls as the wire 122 is wound and unwound, the shaft 120 moves along the opening 113 in the longitudinal direction, thereby providing a camera 12. ) Moves along the rail (11). Although not shown in the drawing, the rail 11 is provided with a power line and a data transmission line for supplying power to the camera 12 and transmitting image data from the camera 12. In addition, the rail 11 may be provided with a plurality of cameras 12 to photograph the abnormal situation using the camera 12 of the closest distance to the sensor that recognizes the abnormal situation, as will be described later.

In the present invention, a sensor 13 is installed in the underground embedding line 20 disposed in the cavity 10. The underground embedding line 20 is disposed in the form of a tube or in the form of an electric wire, as shown in the figure. The sensor 13 is located outside the underground embedding line 20, that is, the outside of the tube or the outside of the wire. It is arranged in plurality at intervals. The type of the sensor 13 is not particularly limited, but may be composed of a temperature sensor for monitoring a fire or the like or a smoke detection sensor for monitoring a smoke or the like. In addition, each of the sensors 13 is provided with individual identification information (identification information) and information on the installation location (for example, the sensor serial number and the corresponding position).

The sensor 13 communicates with the camera 12 to inform the camera 12 of individual identification information and location information of the sensor 13. Therefore, by obtaining the individual identification information and the position information of the sensor 13 from the sensor 13 around the position of the camera 12, it is possible to know where the camera 12 is located.

On the other hand, the joint ball monitoring device according to the present invention is provided with a wireless communication collection terminal 14 for collecting information from the sensor 13 and the camera 12, storing it and transmitting it to the outside of the joint ball. As illustrated in the figure, the wireless communication collection terminal 14 may be installed on the rail (11).

Next will be described a method for real-time monitoring of the joint ball using the joint ball monitoring device according to the present invention having the configuration as described above.

4 shows a schematic flowchart of a method according to the invention.

In everyday situations, the information about the conditions inside the joint sphere 10 is transmitted to the control center outside the joint sphere 10 through the wireless communication collection terminal 14 through the sensor 13 installed in the underground buried ship 20. . Of course, the information collected and transmitted by the sensor 13 is stored in the wireless communication collection terminal 14.

When the sensor 13 encounters an abnormal situation (for example, a temperature rise due to a fire occurrence) in the cavity, the sensor 13 detects this and recognizes data on the situation by its location information and unique identification. The information is sent to the wireless communication collection terminal 14, and the wireless communication collection terminal 14 transmits abnormal situation data and other information to the control center.

5 shows a schematic diagram showing a state in which the camera 12 moves along the rail 11 to the position of the sensor 13, and as shown in the figure, the camera 12 is transmitted from the sensor 13. The sensor 13 is moved along the rail 11 to the position of the corresponding sensor 13 based on the incoming signal, and photographs an abnormal situation in the common sphere in real time to transmit the captured image to the control center through the wireless communication collection terminal 14. do. If the plurality of cameras 12 are installed on the rail 11, the camera 12 located at the most distance from the sensor 13 moves to the sensor 13.

If an abnormal situation occurs between the sensors 13, the exact position at which the abnormal situation occurs can be known through the distance traveled by the camera 12 from the sensor 13 to the abnormal situation occurrence point. Since the camera 12 receives the positional information from the sensor 13, the position of the sensor 13 can be grasped, and the distance traveled by the camera 12 is the movement wheel of the camera 12 along the rail 11. Since the distance from the sensor 13 to the abnormal situation occurrence point can be calculated by using the number 111 rotated, that is, the number of wheel revolutions, the position of the abnormal situation occurrence point can be accurately known.

In this way, the manager visually manages the situation in real time through the photographed image in the common ward transmitted through the moving camera 12, and when an abnormal situation occurs, it is appropriate to solve the abnormal situation according to a predetermined management guideline. Take action.

FIG. 6 is a schematic diagram showing a hat-hiking method proposed by the present invention in order to efficiently manage an image obtained by photographing in a certain direction while moving the camera 12. As shown in FIG. 6, while photographing at a constant frame rate and moving speed using the camera 12, a hatching process is performed with a predetermined distance between the camera 12 and the facility and the direction information of the known camera. If the underground line is made of pipes, a projection transformation may be used.

On the other hand, in the present invention, when the camera 12 is also provided with a sensor, it is possible to exhibit a sufficient monitoring function even in the area where the sensor can not communicate. FIG. 7 is a schematic diagram showing a state where the camera 12 is located in the communication dead zone of the sensor to perform a monitoring function.

As shown in FIG. 7, when the sensors 13 are installed at intervals, the sensor nodes must be connected to transmit data acquired through the sensors. In FIG. 7, the shaded circle means a communicable area. However, in some cases, the sensor 13 in the middle portion may be in an incapable communication state. In this case, in the present invention, by moving the camera 12 to the sensor communication incapable area and by placing the sensor node together with the camera, it is possible to solve the problem caused by the communication inability.

In general, abnormal situations, such as accidents occurring in communal districts, affect the lives of people and property, depending on whether they are properly addressed early on. As described above, according to the present invention, the local area network senses the situation in the community, and can accurately recognize the location of the accident, and can accurately identify and identify the current situation in real time through the camera, the abnormal situation in the community Monitoring in real time can respond appropriately at the early stage to prevent large accidents. In particular, according to the present invention, as compared to the conventional method in which the worker directly enters the cavity and checks and judges the situation, the management cost is low, and it is possible to prevent fatal accidents such as suffocation due to underground spatial features.

In addition, in the constant management of the community, according to the present invention, there is an effect that the cost, time and the like required for monitoring and management of the community are significantly reduced.
