Description
The present invention relates to a fire monitoring technology, and more particularly, by analyzing the video information transmitted in real time through the monitoring system installed in the area that needs to monitor the fire (or disaster) to monitor the occurrence of fire, The present invention relates to a fire monitoring system and a method for monitoring the same so that the monitoring system can be quickly corrected in case of abnormal operation.
In general, a fire prevention system is equipped with a camera or various sensors to monitor the video signal captured from the surveillance camera or the signal detected and input from the sensor, and transmits and alarms the captured video signal and various detection signals, It is to be sent to be monitored.
The fire crime prevention system mainly uses a CCTV method as an unmanned surveillance method, while the overall system configuration is simple and inexpensive, while the video system simply performs an analog video recording function, and the recording medium also uses a VTR. The tape recording time and recycling is also short, irrespective of the specific case, continuous image recording and image quality deterioration and additional functions cannot be extended, and there is a problem that the distance and distance of the remote site are limited.
In other words, the conventional method of storing video signals as described above is to record continuous shooting information on a video tape, which is cumbersome because it requires replacement with a new video tape, and the cost for managing these video tapes is incurred separately. There is a problem.
In addition, the conventional CCTV system has the inconvenience that the user has to play and search the video tape directly in order to retrieve the shooting information of a specific date or time, there is also a problem of degradation of image quality due to the reuse of the video tape and long time recording .
In addition, the conventional CCTV system has a problem that the alternative for securing the shooting information when the system is damaged due to the collapse of the building, such as the monitoring site is not considered.
In addition, the conventional fire security system using CCTV does not properly analyze the video signal captured by the camera, and predicts fire and disaster such as wildfire, smoke, water level rise, landslide, and prevents disaster risks in advance. There is a disadvantage that it is difficult to accurately diagnose the fire crime, such as extremely limited.
Accordingly, the present invention is to improve the conventional problems as described above, while building a surveillance system in conjunction with a digital video recording unit (DVR) installed in the monitoring means and control center installed in the monitoring site, The digital video recorder consists of an intelligent integrated monitoring program that monitors the occurrence of a fire from the video information transmitted from the monitoring means in real time. The objective is to provide a fire monitoring system and its monitoring method that can prevent precautions and, in particular, in the event of a fire, assist in establishing a prompt site identification and countermeasures.
In addition, the present invention is configured to quickly correct the software in the abnormal operation of the monitoring system, by preventing the off time of the video monitoring according to the real-time monitoring to prevent the real-time monitoring function of the fire monitoring system is deteriorated There is another purpose to make it possible.
Fire monitoring system of the present invention for achieving the above object, Surveillance camera for providing real-time video information on the monitoring site; A DVR processing unit connected to the surveillance camera through a communication network and storing and storing the video information provided from the surveillance camera into a digital video signal; To include, The DVR processing unit includes an input unit for capturing the image of the RGB color model in the image information; Equipped with a surveillance application program that extracts the motion region from the image information of the RGB color model inputted from the input unit, filters the extracted motion region image information, and changes the filtered image information to the HIS color model to read a fire occurrence. Fire surveillance micom; An alarm unit controlled by the fire monitoring microcomputer to generate an alarm; And a storage unit for storing the alarm generation history of the alarm unit as well as the image information converted by the fire monitoring microcomputer. .
In addition, the surveillance camera includes a fire detection thermal imaging camera operating in a normal shooting mode or a thermal imaging mode, and an IP camera and a CCTV camera, as well as the general shooting mode or thermal imaging mode of the thermal imaging camera, IP cameras and CCTV cameras are configured to be controlled by the fire surveillance microcomputer through serial communication.
In addition, the fire monitoring micom is driven by an embedded operating system (OS), but when the hardware reset for the embedded operating system (OS) due to abnormal operation of the embedded operating system, the schedule of the hardware reset proceeds The software watchdog application which restores the monitoring application of the monitoring system by software within the time range is installed.
In addition, the software watchdog application monitors whether the monitoring application and the watchdog application of the monitoring system operate normally, but if the process of the watchdog application is not normal, the monitoring application executes the watchdog application. The watchdog application transmits a message to the watchdog application program at regular intervals, and the watchdog application counts a message reception. When the count information exceeds the set number of counts, the watchdog application operates abnormally. After recognizing that the system is forced to reset it and restarting the monitoring application.
On the other hand, the fire monitoring method implemented by the fire monitoring system, the first step of capturing the image information of the RGB color model from the image information, when the image information captured from the scene monitoring camera received at the control center; A second step of extracting a motion region by comparing the image information of the RGB color model captured from the first step with a preset background modeling; A third step of filtering a noise and an unstable area by using a morphology technique in the image information of the motion area extracted from the second step; And converting the image information from which the noise and the unstable region are filtered from the third step into a HIS color model that does not react sensitively to the illuminance conversion, and then determines whether a fire has occurred by using a preset flame color sample. A fourth step of generating an alarm sound if a fire; .
The fourth step may include determining whether the motion region is a flame color through a fuzzy color filter using a preset flame color sample of the image information of the HIS color model; If it is determined that the flame color is defined as a fire suspect area; Generating a two-dimensional histogram and comparing the dynamic characteristic of the flame if it is defined as a fire suspect area from the step; And when the flame color generated in the fire suspect region of the two-dimensional histogram matches the dynamic characteristics of the flame, finally determining the fire to generate an alarm sound, and if not matching, managing the fire suspect region. As shown in FIG.
As described above, the present invention establishes a surveillance system by linking a surveillance means installed at a monitoring site and a digital image recorder (DVR) installed at a control center, while the digital image recorder generates a fire from image information transmitted in real time from the surveillance means. In addition to establishing an intelligent integrated monitoring program that monitors whether there is an abnormality, the system is configured to quickly correct the monitoring system in case of abnormal operation. Through this, it collects the precursor information of the fire through real-time video analysis and predicts the fire. Prevent fire risks in advance, and in particular, in the event of a fire, it is possible to promptly identify the site and establish countermeasures, while preventing off-time of video monitoring due to real-time monitoring. Expect effects to prevent being That would be.
