Description

[0001] Emergency sensing apparatus and method therefor [0002]

The present invention relates to a method and an apparatus for detecting an emergency situation that are difficult to predict, such as a forest fire or a landslide, and can be quickly dealt with when an emergency situation occurs unexpectedly.

Conventional technology related to detection of fire is to receive data from video surveillance cameras installed in the relevant surveillance area and data from meteorological observation devices in a remote control room and then to conduct efficient fire surveillance and to take prompt action in case of fire A fire detection system including a fire detection system and a control room terminal using a method for detecting an automatic fire detection system and a control method thereof and a fire detection system using a fire detection system using a thermal image analysis, A CCD camera for capturing a CCD image and transmitting the captured image to a control unit, and a panoramic image correction unit for generating a panorama by correcting temperature and distortion of the thermal image transmitted from the infrared camera, Create image fusion through image image and compositing And there is a method of judging whether or not a fire occurs by analyzing the temperature of the photographing area through this.

In addition, a fire detection system for judging whether or not a fire (forest fire) has occurred by analyzing a video image and a temperature measured from a video camera to be photographed and a thermal camera for detecting heat, and a control method thereof have been used.

Conventional technologies for detecting landslides are as follows.

The Forest Service operates "Landslide Prediction Information" and "Landslide Risk Map". The "Landslide Prediction Information" estimates the amount of rainwater in soil based on past landslide analysis results (tank model) It is practically impossible to set the forecasting standard (tank model) to reflect all the detailed soil characteristics (permeability, groundwater level, etc.) in each region according to the index. Therefore, a localized landslide prediction And "Landslide Risk Map" is based on landslide occurrence history data (2,000 places) of past forests in the past. Using logistic regression analysis, weighted according to the influence of each factor, the probability of landslide occurrence is calculated as 5 The factors that affect landslides are very diverse, but the landslide risk maps are classified into clinical, , Slope inclination, and so on.

Also, according to the conventional technology related to the landslide, an environmental index such as rainfall, wind speed, and illuminance, and a position change value of the branches positioned at predetermined shooting points that can judge occurrence of a landslide are detected, The alert server stores the 'normal' step, the 'alert' step, and the 'advisory' step of the reference value information field corresponding to the value of the ' There is a method of transmitting the detected result to the relevant resident management center.

The area to be monitored is very large because it is necessary to monitor the urgent situation such as forest fires or landslides in a sudden situation nationwide. Therefore, since the number of points to be monitored is very large, the amount of data transmitted to the point for initial response by checking the monitoring information must be minimized, and since a monitoring device must be installed and operated for each monitoring point, Cost should also be minimized. Since an immediate initial response to these surveillance devices is indispensable, a system capable of recognizing the occurrence of a situation more concurrently than a stepwise information delivery system is required.

The present invention relates to an emergency situation detection and alarm message transmission method for promptly coping with an emergency situation that arises unexpectedly, such as a forest fire, a landslide, or the like, that is, a natural disaster situation, And to provide a method for transmitting a minimum amount of sensed data.

According to an embodiment of the present invention, a reference information acquisition unit for acquiring reference information including positional information and monitoring time information of a surveillance target area, a surveillance situation information acquisition unit for acquiring surveillance situation information including image information or situation information of the surveillance target area, An emergency acquiring unit, an emergency situation determiner for determining whether an emergency situation is present based on whether the variation of the monitoring situation information exceeds a preset threshold within a predetermined time in the monitored area using the reference information and the monitoring situation information, And an emergency notification unit for transmitting the location information and the related information of the area when it is determined to be the situation.

The present invention provides a method and apparatus for detecting an emergency situation that is difficult to predict, such as a forest fire, a landslide, and the like, and quickly responds to an emergency situation that occurs unexpectedly, thereby reducing manpower required for monitoring an emergency situation and cost loss There is an effect.

In addition, since the emergency situation detection method employing the simplified emergency state detection method and the minimum detection data information transmission method provided in the present invention is easy to implement and operate at the detection point, maintenance cost and power There is also an effect of reducing consumption.
