The present invention relates to a slope management monitoring system, and more specifically, to control the operation of the image acquisition device in the data collection device installed in the field when the slope abnormal behavior occurs to capture the image information of the region where slope behavior occurred to the management server It relates to a sloped image transmission system that provides more quickly.

In general, the slope is difficult to grasp the characteristics in the pre-investigation stage for the construction of the slope because the soil and geological characteristics are complex and engineering characteristics are heterogeneous. Therefore, there are many cases in which collapse accidents occur during construction of slopes or after road opening, or sufficient safety cannot be secured due to design conditions and other ground characteristics.

As a result, the prediction of slope behavior and actual behavior are often inconsistent, so one of the methods to solve these problems is to identify slope behavior during and after construction, and take appropriate countermeasures when abnormal signs are found. .

In particular, the safety of slopes is assessed from the perspective of disaster prevention by the maintenance of slopes formed on both sides of the road, and the slopes determined to be at risk of collapse are measured to understand the behavior in advance to minimize damage. Possible measures should be considered.

In recent years, various types of slope management systems have been developed to monitor the behavior of slopes and images on slopes using a measuring device that measures the slope state in real time and an image acquisition device that captures the surveillance image of the slope. It became.

One example of this is Korean Patent Application Publication No. 2004-3487 filed by Korea Institute of Construction Technology.

However, in the conventional real-time unmanned surveillance system for slope management, it is difficult to obtain more detailed image information on the slope as the surveillance image of the slope through the slope monitoring image acquisition device is fixed in a certain direction.

Accordingly, there has been considerable difficulty in determining the initial activity, i.e., the movement of the slope, in the region where the slope is expected to collapse using the image information acquired through the surveillance image acquisition device.

Even if the camera is a camera that can be controlled remotely from the remote management server, such as zooming or rotating the camera, the administrator must always stay in the place where the management server controlling the operation of these devices is located and manually control it remotely through monitoring. Therefore, when the slope surface movement occurs when the administrator is away, since the accurate surveillance image information on the corresponding area cannot be obtained, the initial response to the movement of the slope surface is delayed.

The present invention has been invented to solve the above problems, the control of the image acquisition device in the data collection device installed in the field when the slope of the abnormal behavior occurs to capture the image information of the region where slope behavior occurred to the management server It is an object of the present invention to provide a slope transmission image transmission system that provides more quickly.

It can be provided to the management server.

In particular, even if an administrator who monitors the slope on the management server side is away, the video information about the initial process of the slope movement starts automatically is recorded so that the recorded slope can more accurately predict the slope of the slope. The damage caused by the collapse will be reduced.

It is advantageous to allow for continuous use.

In the embodiment of the present invention, the memory 340 stores identification information of the management server and the data collection device, location information of each sensor installed on the slope, current direction information of the pan / tilt camera, and an operation program.

In the embodiment of the present invention, the memory 340 is composed of a nonvolatile semiconductor such as, for example, an EEPROM or a flash ROM, so that data is preserved even in a state where power is lost.

The memory 340 may be physically composed of two memories, read-only and write / read, but in a preferred embodiment, is composed of a single nonvolatile memory capable of writing / reading.

The controller 350 outputs a camera driving signal according to a camera control signal of the management server 500 input through the video server 320.

In addition, the control unit 350 outputs a camera driving signal according to a camera control signal input from the data collection device 100 through the communication unit 330.

That is, in the embodiment of the present invention, the control unit 350 includes a data analysis unit 351 for analyzing the camera control signal of the management server 500 or the camera control signal of the data collection device 100.

Accordingly, the control unit 350 controls the camera control signal input from the video server 320 through the data analysis unit 351 or the camera control signal of the data collection device input from the communication unit 330. The identification information is compared with the identification information stored in the memory 340 to analyze whether the corresponding camera control signal is a signal requested to the user.

In addition, the control unit 350 includes a driving control unit 352 for outputting a camera driving signal according to the control signal when the analysis result of the data analysis unit 351 is a signal for itself.

Accordingly, the control unit 350 outputs a camera driving signal according to the camera control signal to the camera driving unit 360 through the driving control unit 352 to remotely control the driving of the pan / tilt camera.

In addition, the camera driver 360 operates by rotating the pan / tilt camera 310 to capture a surveillance image of a region where a corresponding sensor is installed according to a camera driving signal of the driving controller 352.

Therefore, the image capturing apparatus 300 having the above configuration captures the surveillance image of the corresponding area and transmits the surveillance image to the management server according to the camera driving signal transmitted from the management server 500 and the data collection apparatus 100.

That is, when the camera driving signal of the management server 500 is input through the video server 320, the control unit 350 analyzes whether the camera driving signal received through the data analyzer 351 is its own signal and In the case of a signal, a driving command included in a camera driving signal is performed.

For example, when the driving command is a horizontal and vertical rotation command for the pan / tilt camera, the driving controller 352 may refer to the current direction information of the pan / tilt camera stored in the memory 340 to refer to the pan / tilt camera 310.

The pan / tilt camera is driven.

For example, when an operating program is programmed to capture an enlarged surveillance image of a corresponding region, the driving controller 352 of the controller 350 may horizontally refer to the current direction information of the pan / tilt camera stored in the memory 340. In response to the vertical rotation command, the pan / tilt camera 310 is rotated and driven, and the lens of the pan / tilt camera 319 is zoomed in to capture a surveillance image of an area in which the corresponding sensor is mounted.

As described above, the operating program stored in the memory to capture the surveillance image of the slope according to the camera driving signal of the data collection device may be variously implemented according to the programmed operating method.

By transmitting the control signal and automatically transmitting the image information of the area where the device on which the slope is generated is installed to the management server, it is possible to respond more quickly to the behavior of the slope on the management server side.

In particular, even if an administrator who monitors the slope on the management server is away, the video information about the initial process of the movement of the slope is automatically recorded, so that the direction of slope collapse can be more accurately predicted through the recorded image information. The damage caused by the collapse of the slope will be reduced.

Meanwhile, according to an additional embodiment of the present invention, the controller 350 of the image capturing apparatus further includes a data processor 353 supporting data communication between the management server 500 and the data collection apparatus 100.

In this embodiment, when the measurement data request signal is input from the management server 500 through the video server 320, the data processor 353 outputs the measurement data request signal to the communication unit 330.

When measurement data corresponding thereto is input from the data collection device 100 through the communication unit 330, the measurement data is output to the video server 320.

Therefore, according to the configuration described above, in the image transmission system of the slope according to the present invention, when a failure occurs in the mobile communication network, which is a communication network between the data collection device and the management server, data communication between the data collection device and the management server is possible through the image acquisition device. By doing so, it is possible to continuously monitor and manage the behavior of the slope on the remote site.
