Description

Indoor fire prevention notification system and its method {SYSTEM AND METHOD FOR ALARMING INDOOR FIRE PREVENTION}

The present invention relates to an indoor fire prevention notification system and method thereof, and more particularly, to collect sensing information from a plurality of fire detection sensors according to a preset collection period, and to generate abnormalities in fire in the sensing information of a specific fire detection sensor. When a symptom is detected, by changing the collection period to quickly collect more sensing information, and by monitoring that another abnormal symptom is detected in each of the collected sensing information, the occurrence of a fire is predicted and notified in advance. In addition, if it is determined that a fire has occurred as a result of the above monitoring, fire occurrence notification and escape routes are promptly provided to the user terminal to prevent the occurrence of fire. It relates to an indoor fire prevention notification system and a method that can be minimized.

Due to the recent development of industrial technology and construction technology, most of the buildings are getting higher and higher density, and if a disaster such as a fire occurs, there is a problem that not only property damage but also life damage may increase rapidly.

Accordingly, in areas where human and property damage is expected to be large due to fire, such as public institutions, apartments, subways, schools, factories, airports, etc., fire detection is used to detect fires and promptly respond to them. The need for systems is gradually increasing.

In particular, in order to minimize the damage caused by fire, it is very important to prevent fire by predicting and taking action in advance. In the event of a fire, it is very important to quickly respond to it and at the same time in the area where the fire occurred. It is also an important factor to provide safe escape routes for those who are located in the city.

In addition, another important element of the fire detection system is to accurately detect the occurrence of fire and reduce misinformation about the occurrence of fire, thereby minimizing the inconvenience of people or managers located in the area.

However, in the conventional fire detection system, the administrator directly monitors CCTV images transmitted in real time from a plurality of CCTVs installed in a plurality of areas in a building, and the user directly performs a fire alarm according to the monitoring result. There is a problem that the manager must perform the above monitoring and a separate manpower is required.

In order to solve this problem, recently, various fire detection sensors such as flame sensor, smoke sensor, temperature sensor, etc. have been installed to automatically detect the occurrence of fire based on sensing information received from each sensor. A fire detection system using a fire detection sensor that provides automatic notification to fire response organizations has been developed and is being commercialized.

However, in the case of a fire detection system using a conventional fire detection sensor, it is not intended to prevent fire by predicting the occurrence of fire in advance, but to detect the occurrence of fire using sensing information received from the plurality of fire detection sensors. It already has a structure in which damage from fire is bound to occur.

In addition, the conventional fire detection system using a fire detection sensor considers that a fire has occurred when more than a temperature value set in advance by the fire detection sensor is detected, a flame is detected, or smoke is detected. If not, there is a problem of causing unnecessary dispatch of fire response agencies or unnecessary evacuation of people located in the area.

That is, the conventional fire detection system using a fire detection sensor has a problem that may cause discomfort for people, since misinformation about the occurrence of a fire may occur frequently.

Accordingly, in the present invention, sensing information is collected from a plurality of fire detection sensors including an overcurrent detection sensor, a smoke detection sensor, a temperature sensor, and a camera sensor according to a preset collection period, so that a fire occurs in a specific fire detection sensor. When an abnormal symptom is detected, the collection period for each fire detection sensor is shortened to collect a lot of sensing information, and the collection period is shortened to monitor the collected sensing information in a complex manner to accurately predict the occurrence of fire. As a notification, it is possible to prevent the occurrence of a fire in advance, and at the same time, it is possible to prevent misinformation about the occurrence of a fire, and when it is determined that a fire has occurred, the user's terminal will be notified of the fire occurrence and the farthest It is intended to propose a method to minimize the damage to property and human life due to fire by providing an escape route that guides the user to the nearest exit among the distant exits in augmented reality, virtual reality, or a combination thereof.

That is, the present invention does not simply detect the occurrence of fire using only individual sensing information of the fire detection sensor, but varies the collection period of the sensing information according to whether abnormal symptoms are monitored through a plurality of fire detection sensors, By collecting more sensing information for the plurality of fire detection sensors and detecting the occurrence of complex abnormalities in the collected sensing information, the occurrence of fire can be accurately predicted in advance so that fire can be efficiently prevented. will be.

That is, the fire prevention notification device 100, when a fire occurrence abnormal symptom is detected by a specific sensor, by varying and setting the sensing information collection period, more data (ie, sensing information) for predicting fire occurrence It is collected so that the occurrence of fire can be accurately predicted.

Thereafter, the fire prevention notification device 100 calculates an increase/decrease pattern for the sensing information collected according to the shortened sensing information collection period, and monitors the trend for the calculated increase/decrease pattern. When an abnormal sign of fire occurrence is detected, it is predicted that a fire will occur, and information about it is transmitted to the manager terminal 400 and the fire response organization 500 so that the relevant area can be quickly identified, thereby preventing the occurrence of a fire. It should be prevented in advance.

Meanwhile, the increase/decrease pattern refers to the amount of change in the sensing information over time, and is calculated by dividing the sensing information accumulated and stored according to the collection period by unit time, and the description of the increase/decrease pattern is shown in FIG. It will be described in detail with reference to.

In addition, the fire prevention notification device 100, as a result of monitoring the trend of the increase/decrease pattern, the increase/decrease pattern rapidly increases by exceeding a preset threshold value, or the sensing information of each sensor is a preset threshold value. If it exceeds, it is determined that a fire has occurred, and a notification is provided to the manager terminal 400 and the fire response organization 500, so that a quick response to the fire can be performed.

In addition, the fire prevention notification device 100 stores the actual map of the room and the location information of the emergency exit in advance, and when it is determined that the fire has occurred, the fire prevention notification device 100 By overlaying the fire occurrence-related information and the escape route on the real map according to the location information of the user with the user terminal 300 of the located user, the escape route is provided in virtual reality or augmented reality, and the escape route is Increase the visibility of people so that they can evacuate quickly.

And, by executing the installed escape route providing application or program, the escape route may be provided from the topic prevention notification device 100. Meanwhile, a method of providing the escape route will be described in detail with reference to FIG. 6.

2 is a diagram illustrating a process of predicting and detecting a fire occurrence based on sensing information received from a plurality of fire detection sensors in an indoor fire prevention notification system according to an embodiment of the present invention.

As shown in FIG. 2, the process of predicting and detecting the occurrence of a fire in advance through the indoor fire prevention notification system 10 according to an embodiment of the present invention is, first, fire detection installed in a plurality of indoor areas. The sensor module 200 collects sensing information from the plurality of fire detection sensors according to a preset sensing information collection cycle and transmits it to the fire prevention notification device 100 (①).

Meanwhile, the sensing information includes location information for a specific area in the room in which the corresponding fire detection sensor module 200 is installed, and each fire detection sensor included in the fire detection sensor module 200 has its own unique Each of the sensing information is collected according to one function, so that the collected sensing information can be transmitted through the fire detection sensor module 200.

On the other hand, when the fire detection sensor is not composed of the fire detection sensor module 200 but is installed independently, the collection and transmission of the sensing information, and the setting of the sensing information collection period are also performed for each of the fire detection sensors. At this time, the newly set sensing information collection period setting information is transmitted to other fire detection sensors adjacent to the fire detection sensor including the fire detection sensor in which the corresponding abnormal symptom is detected.

That is, when an abnormal symptom is detected by a specific fire detection sensor, the fire prevention notification device 100 collects and monitors more data (that is, sensing information) to accurately predict the occurrence of fire in advance and prevent misinformation. The sensing information collection period is shortened so as to be newly set.

Next, the fire prevention notification device 100 calculates and monitors (⑤) an increase/decrease pattern for the sensing information received according to the newly set sensing information collection period, and other than the fire detection sensor in which the abnormal symptom is detected. When another abnormal symptom is detected in the sensing information of other fire detection sensors, by determining that a fire will occur, the occurrence of a fire is predicted in advance (⑥), and the predicted result is determined by the manager terminal 400 or the fire. By notifying (⑦) to the response organization 500, the occurrence of fire can be prevented in advance.

At this time, the fire prevention notification device 100 calculates the increase/decrease pattern by shortening the unit time in order to more closely monitor the abnormal symptoms of the sensing information.

On the other hand, the fire prevention notification device 100, in the case that the abnormal symptom is not detected by the other fire detection sensor as a result of the monitoring, the manager terminal 400 together with the location information on the specific fire detection sensor in which the abnormal symptom was detected. ) To indicate that an abnormal symptom has been detected, so that the relevant area can be identified.

At this time, the fire prevention notification device 100 sets the newly set sensing information collection period as the original sensing information collection period so that the operation of each fire detection sensor can be restored to its original state.

On the other hand, when monitoring the trend of the increase/decrease pattern for the sensing information received according to the variable collection period, the trend of the increase/decrease pattern increases at a rate exceeding a preset threshold, or the sensing information is preset. When the threshold value is exceeded, the fire prevention notification device 100 determines that a fire has occurred in the corresponding area (⑥).

Thereafter, when it is determined that a fire has occurred, the fire prevention notification device 100 notifies (⑦) the monitoring result to the manager terminal 500 and the fire response organization along with the location information of the corresponding area.

On the other hand, the sensing information increase/decrease pattern is calculated when the sensing information accumulated and stored in the chronological order is greater than or equal to a preset number, and means a change amount of sensing information over time, and the accumulated sensing information is unit time. By differentiating with, the calculation is as described above.

The calculated sensing information increase/decrease pattern may predict the occurrence of a fire in advance or detect the occurrence of a fire by monitoring the trend of the change of each sensing information.

4 is a diagram illustrating a method for predicting or detecting a fire occurrence by calculating an increase/decrease pattern of sensing information according to an embodiment of the present invention.

As shown in Figure 4, the method of calculating the sensing information increase or decrease pattern according to an embodiment of the present invention, first accumulates sensing information for each fire detection sensor according to the fire detection sensor module 200 in a database in time order. It is performed by calculating the amount of change in sensing information for each of the stored sensing information.

In other words, the sensing information increase/decrease pattern is set in advance, or after an abnormal symptom is detected in specific sensing information and the sensing information is stored in chronological order as the sensing information collection period is varied. It is calculated by calculating the amount of change in the sensing information accordingly.

When a symptom is detected, it predicts that a fire will occur, and the monitoring result and location information of the corresponding region are provided as a notification to the manager terminal 400 and the fire response organization 500. On the other hand, when calculating the increase/decrease pattern for the collected sensing information by shortening the collection period, the fire prevention notification device 100 further precisely monitors the increase/decrease pattern of the sensing information. It is set so that the increase/decrease pattern can be calculated.

At this time, the abnormal symptom detection refers to a trend in which the calculated increase/decrease pattern is continuously increasing or the calculated increase/decrease pattern rapidly increases (i.e., when the trend changes rapidly). When abnormal symptoms occur in combination in the plurality of fire detection sensors, the fire prevention notification device 100 predicts that the fire will occur.

In addition, the fire prevention notification device 100, in the process of performing the monitoring by newly setting a collection period (i.e., shortening the collection period), the trend of the calculated increase/decrease pattern exceeds a preset threshold and increases rapidly. When it is detected or the sensing information (eg, temperature value) exceeds a preset threshold (eg, 100°C), it is considered that a fire has occurred in the area, and the monitoring result for this is reported to the manager terminal ( 400) and by providing notification to the fire response organization (500).

At this time, the stored sensing information means a numerical value measured by each of the sensors, and when the fire detection sensor is an overcurrent sensor, a temperature sensor, or a chemical substance detection sensor, an overcurrent value, a temperature value, and a chemical substance concentration value Means each.

In addition, when the fire detection sensor is an image sensor and smoke is detected through the image sensor, a smoke part is extracted from the image using a characteristic value for the smoke, and the area of the extracted smoke part is calculated from the image. As a result, the corresponding area is stored in the database 700 as sensing information on the smoke, or the concentration value of the smoke particles in the air detected through a laser sensor is used as sensing information on the smoke, and the database 700 is Can be saved on.

That is, in the present invention, receiving and storing the sensing information on the smoke may be performed through a known image processing technology or various smoke sensors, and there is no limitation on this.

In addition, the fire detection sensor may be stored in the database 700 by setting it as 1 when the fire detection sensor is an odor detection sensor, and when a preset odor is detected, and 0 when other odors are detected.

However, since general odor detection sensors operate to detect odors based on chemical substances in the air, it is sufficient to measure the concentration of harmful chemical substances in the air through the chemical substance detection sensor, so a separate odor detection sensor is not provided. It can be implemented so that prediction about the occurrence of the fire can be performed without.

In addition, the sensing information increase/decrease pattern calculation unit 120 performs a function of calculating an increase/decrease pattern for each sensing information stored in the database 700 in chronological order.
