Description

A fire monitoring system and method that can automatically notify in real time {A FIRE MONITORING SYSTEM OF AUTOMATIC NOTIFICATION IN REAL TIME AND METHOD THEREOF}

The present invention relates to a fire monitoring system and method capable of real-time automatic notification, and more particularly, a fire monitoring system capable of effectively improving an initial response speed to a fire site by transmitting a fire risk signal in real time to personnel capable of dispatching a field. And a method.

The dangerous area fire monitoring system is characterized by detecting wind direction and wind speed and updating data approximately every 10 minutes with an IoT platform server (hereinafter, also referred to as “KEPCO branch”). At this time, when a danger signal is detected in a certain place, employees at KEPCO's regional branch offices near the site where the danger signal occurred, and the staff at the local branch of KEPCO confirm it, and request a response person (hereinafter referred to as “site staff”) to be dispatched to the site.

Specifically, since the KEPCO server linked to the server collecting disaster disaster signals uses a closed network for strong security, communication is limited because it is a one-way transmission method that transmits data to the outside using SMS (Short Message Service). . In other words, the closed network KEPCO server only transmits messages to the KEPCO branch office, and it is difficult to communicate with on-site staff in connection with on-site dispatch, which causes a serious situation in which the communication process is delayed in situations where on-site dispatch is impossible. . In addition, since the received signal is updated every 10 minutes, if a fire occurs immediately after the update, an abnormal signal is discovered after a certain period of time has passed at the branch of KEPCO. For this reason, if the on-site response is delayed even a little in the process of delivering the branch employee to the on-site employee, there is a problem that serious property damage or personal injury may be caused.

In other words, since the conventional fire monitoring system uses the one-way transmission method of KEPCO, the fire situation is shared only to volunteers who are requested to be dispatched to the field, so there is a limit to more rapid on-site response.

Therefore, it is necessary to develop a system that can quickly respond to the site by overcoming the limitations of KEPCO and sharing a danger signal with personnel who can be dispatched near the fire site.

The present invention was conceived to cope with the above-described technical problems, and an object of the present invention is to substantially compensate for various problems caused by limitations and disadvantages in the prior art. It is to provide a fire monitoring system and method including an automatic notification function that can effectively improve the on-site response speed by transmitting a disaster risk signal.

In order to solve the above-described problem, a fire monitoring system according to an embodiment of the present invention includes: an IoT platform server for monitoring an event in real time through a flame detector and a weather data collector; And a plurality of application servers that receive an on-site dispatch request message for an event from the IoT platform server in the form of SMS and are connected through a mesh network, wherein the application server is limited to the participant's device receiving the security authentication link. The SMS can be delivered sequentially between participants based on a predetermined priority.

In addition, the SMS includes fire information including an address of a fire occurrence point, a time of the fire, and a real-time image for confirming the fire occurrence site, and the fire information may be confirmed by at least one of text and URL.

In addition, the SMS may further include a user interface for selecting whether or not the on-site response personnel can be dispatched.

In addition, the predetermined priority may be determined based on the order of participants located in a short distance from the fire occurrence point.

In addition, the predetermined priority may be determined based on the order of participants with a fast response speed or the order of participants with a fast on-site dispatch based on current traffic conditions.

In addition, when the application server receives a response from the user interface that the participant is not allowed to go to the field, the application server may deliver the SMS to the next participant based on a predetermined priority.

In addition, the IoT platform server may include a fire determination unit, and the fire determination unit may calculate a fire risk level capable of confirming a risk stage of a fire by comparing the flame data and meteorological data collected from the flame detector and the meteorological data collector.

In addition, the fire risk is the following equation (Equation) [C] X [H] / ([C] + [H]) + [W] (where C is temperature (°C), H is humidity (%) , W represents the wind speed (m/sec)).

In addition, the fire risk is in the form of a pie-type instrument panel divided into three stages based on a predetermined numerical range, and the IoT platform server is displayed on the display unit, and the pie-type instrument panel can display the risk level in different colors for each stage. .

Hereinafter, a fire monitoring system capable of automatic notification in real time will be described with reference to FIG. 1.

1 is a block diagram of a fire monitoring system according to an embodiment of the present invention.

Referring to FIG. 1, a fire monitoring system 1000 capable of automatic notification in real time includes an IoT platform server 100 and an application server 200.

The fire monitoring system 1000 capable of automatic notification in real time effectively improves the on-site response speed by exchanging messages between on-site dispatchers using a mesh network for the purpose of rapid on-site response according to fire risk detection. It is a capable system. Referring to FIG. 1, a fire monitoring system 1000 capable of automatic notification in real time is connected through a network communication network with an IoT platform server 100 that automatically notifies a call message for on-site dispatch by monitoring a fire situation in real time. It may be composed of at least one application server 200 for sending and receiving SMS for on-site response.

The IoT platform server 100 includes temperature, humidity, and wind direction from meteorological data collectors such as thermometers, hygrometers, wind vanes and anemometers attached to switch poles (hereinafter referred to as "telegraph poles"), flame detectors that detect sparks or flames, and cameras. , Weather data such as wind speed and flames are monitored in real time. It is characterized in that the fire risk is determined based on the monitoring result, and SMS is automatically notified to the participant's application located near the fire occurrence point when the fire risk level is higher than the pre-stored fire risk level in the server. In this case, it is preferable that the SMS transmitted by the IoT platform server 100 to the participant's application is the first SMS transmitted. That is, the first SMS is transmitted from the IoT platform server 100 to the application server 200, but when the corresponding SMS is transmitted to the other application server 200 as necessary, the SMS is transmitted using a mesh network. That is, it is preferable to understand that the IoT platform server 100 does not intervene in the SMS delivery when the first transmitted SMS is transmitted to the other application server 200 again.

The application server 200 refers to an app that is connected to a mesh network (hereinafter, also referred to as “mesh network”) and receives SMS for quick on-site response. The application server 200 is characterized in that it is installed limited to field responders (hereinafter, referred to as “participants” of the fire monitoring system) who have received the security authentication link LI from the IoT platform server 100. The security authentication link (LI) is an app installation link provided to use the service to participate in the fire monitoring system, and has an effect of preventing the installation of users who are not related to the fire monitoring system. Accordingly, only a person who has received the security authentication link (LI) can participate in the fire monitoring system 1000 according to an embodiment of the present invention, and only one security authentication link (LI) is provided per person. It is done.

In addition, the participant of the fire monitoring system 1000 is characterized in that at least one person is a field response manpower of the KEPCO branch located in a specific area, and when there are two or more, they are connected through a mesh network to transmit and receive SMS. Therefore, the plurality of application servers 200 connected to the mesh network within the fire monitoring system 1000 are SMS (hereinafter referred to as'request information for site dispatch (IN)) to know whether the application server 200 can be dispatched to the site. Also known as'). Accordingly, if the on-site response is not possible, when an SMS (hereinafter, referred to as'impossible message') indicating that on-site dispatch is impossible is transmitted to the other application server 200, the other application server 200 receiving the impossible message is sent back on-site. You will check the answer as to whether it is possible or not. At this time, if the other application server 200 also responds that it is impossible to go to the site, a process of delivering an SMS indicating whether the site is possible to be dispatched to another application server 200 is performed, and possible applications among a plurality of application servers The above process is repeated until the server 200 appears. In this case, it is preferable to understand that the SMS is delivered based on a predetermined priority. A database for a predetermined priority (hereinafter, also referred to as a “priority DB”) is stored in each application server 200 by default. More details will be described later.

In addition, a participant of the fire monitoring system 1000 is characterized in that it is possible to determine whether a field response is possible according to the occurrence of a fire. In this case, when there are two or more participants, it is characterized in that they respond to the occurrence of a fire based on a predetermined priority for on-site response between the participants. At this time, the priority is based on determining the person in charge (ie, participants) for each area within a region, and then determining the participant located in a short distance from the fire occurrence point. Accordingly, when the fire occurrence point is changed, the priority may be changed based on the changed fire occurrence point. Specifically, when a fire breaks out at point A, the priority for dispatching the site is determined in the order of participant 1, participant 2, and participant 3 located at a close distance from point A, and the fire occurs at point B far from point A. When it occurs, priority for dispatching to the site can be determined in the order of Participant 3, Participant 2, and Participant 1, centering on point B. At this time, the distance between the fire occurrence point and the participant is characterized by being calculated using the GPS of the application installed by the participant. Meanwhile, since FIG. 1 exemplarily shows that SMS is transmitted between applications APP based on priority, the transmission order may be changed.

Accordingly, the fire monitoring system 1000 may quickly determine whether a participant can be dispatched based on a predetermined priority because it may be impossible to respond on-site by a participant working in a place adjacent to the fire. There is an effect on the composition that can be prepared.

In the fire monitoring system 1000 of the present invention, since a plurality of application servers 200 are connected through a mesh network, even if a separate authentication server does not exist, only authenticated participants can monitor fire and respond on-site. A more detailed description related thereto will be described later.

In addition, the application server 200 is characterized in that it receives from the IoT platform server 100 a short message service (SMS), which is a message for calling, from the IoT platform server 100. In this case, the SMS is automatically notified to the participant corresponding to the area to which the fire occurred, and when the on-site response of the selected user is impossible, the SMS is sequentially transmitted based on the above-described priority.

SMS is characterized by including a URL (Uniform Resource Locator) with a user interface (UI) for selecting the address of the fire location, the time of the fire, and a real-time video that can check the fire site, and whether or not the site can be dispatched. It is done.

Meanwhile, in the present specification, the application server 200 may be referred to as an application or an application or an app for convenience of description.

Hereinafter, the IoT platform server 100 and the application server 200 of the present invention will be described in detail with reference to FIGS. 2 to 6.

2 is a block diagram of an IoT platform server according to an embodiment of the present invention. 3 is a block diagram of an application server according to an embodiment of the present invention. 4A is an exemplary view showing a dashboard according to an embodiment of the present invention. 4B is an exemplary screen diagram for statistical items according to an embodiment of the present invention. 5A to 5B are exemplary screen views illustrating a method of responding to request information for dispatching a fire site according to an embodiment of the present invention. 6 is an exemplary view illustrating a method of distributing an SMS and distributing personnel in charge of each area in a dangerous area according to an exemplary embodiment of the present invention.

Referring to FIG. 2, the IoT platform server 100 includes a monitoring unit 110, a fire determination unit 120, a collection unit 130, a message transmission unit 140, a control unit 150, and a display unit 160. Includes.

Specifically, the monitoring unit 110 collects meteorological data and flame data from meteorological data collectors and flame detectors attached to a plurality of electric poles, and monitors the IoT platform site situation in real time.

The fire determination unit 120 compares the meteorological data and flame data values collected by monitoring with preset values to determine whether a fire has occurred, and determines the degree of danger of the fire. Calculate the fire risk divided by (bottom). Specifically, when the signal collected from the monitoring unit 110 is greater than or equal to a preset value, it is determined that a fire has occurred, and the fire risk may be calculated using the following <Equation 1>.

<Equation 1>

[C] X [H] / ([C] + [H]) + [W]

Here, C is the temperature (°C), H is the humidity (%), and W is the wind speed (m/sec).

As shown in Equation 1 above, the fire risk is calculated based on variables of temperature, humidity, and wind speed and expressed as a numerical value. At this time, the numerical value of the fire risk (hereinafter, also referred to as the'fire risk value') is expressed as a number between 1 and 100, the fire risk'high' has a number between 91 and 100, and the'medium' is 71 to 90. It has a value between, and'lower' is characterized by having a value between 0 and 70. The fire risk value is characterized in that it is displayed on the dashboard of the display unit 160 in the form of a pie-shaped instrument panel as shown in FIG. 4A.

As shown in FIG. 4A, the display unit 160 has a menu area 407 disposed at the top, and an image display area and a map MA showing the locations of electric poles distributed in a specific area on the map MA. The status display area in the form of an icon (405, hereinafter,'status display icon) in the form of an icon connected to each pole displayed in by a line and displaying data collected from each pole (for example, fire status, fire risk, weather data, real-time video data, etc.) ') is placed. The status display area is formed equal to the number of electric poles, and as shown in FIG. 4A, nine status display regions are formed for nine electric poles displayed on the map MA on the dashboard 400.

The menu area 407 includes five categories, for example, a dashboard, an event list, statistics, My Page, and categories for administrators. 4A shows an example of a screen in which a dashboard is selected in the menu area 407. In the event list in the menu area 407, a table consisting of items such as fire status, location, date and time of occurrence, humidity, wind speed, fire risk value, fire status, video attachment (video taken with a camera), etc. You can check the (Table). Here, the video is automatically input in connection with an image server (NVR). However, it is characterized by being applicable only to data within the storage period of the IoT platform server and NVR system. Accordingly, the user can search for desired data for each item in the event list.

In addition, in the statistics item in the menu area 407, a graph in the form of a cumulative bar or a donut indicating the number of events for each event type according to the location of a specific period is shown. Accordingly, referring to FIG. 4B, the horizontal axis represents the type of event and the vertical axis represents the number of events. Event types can include fire occurrence, flame detection, fire risk level, drying alarm and strong wind alarm, and the number of event occurrences according to the event type is displayed on the graph, and detailed information is displayed by selecting the number displayed on the graph. A pop-up window 409 that can be checked is formed, and a list of event occurrences for the entire area is displayed on the pop-up window 409.

In the status display area 405, a pie-type instrument panel 401 in which fire risk values are displayed in upper/middle/lower range, a risk level area 402 that displays fire risk values divided into upper/middle/lower levels, and a weather data icon 403 , You can view the fire status display icon 404, which simply displays the fire status in the form of an icon such as'normal/abnormal/fire risk level/flame detection/network failure' and real-time video collected from the camera attached to each pole. It includes a real-time video view icon (406). Since the pie-type instrument panel 401 displays the fire risk in different colors for each stage, and provides a risk level with an arrow indicating the level of the fire risk level of the pole in the lower center, the user can visualize the degree of fire risk. This can be easily distinguished. In addition, since the fire risk level is displayed in the same color as the fire risk level indicated in different colors, the fire response personnel can more easily grasp the fire risk. When the real-time video view icon 406 is selected, it can be confirmed that the state of the Goseonggan 297 pole is normal through a real-time image in the form of a pop-up window as shown in FIG. 4A, and according to an embodiment, a fire state is displayed due to a network error. In case the fire condition is incorrectly determined by the icon 404, or to double check the fire condition, the user interface that can check the answer to whether it is a fire (Yes) or not (No) is at the bottom of the real-time video screen ( UI) can be provided.

In the event of a fire, the collection unit 130 collects participant information in order to transmit SMS to participants, that is, the on-site response history of the KEPCO branch that participated in the IoT platform server 100.

The message transmission unit 140 transmits the fire information in the form of SMS to a nearby application so that the on-site response personnel (or participants) can dispatch to the site in the event of a fire, but transmits only the participant's app that has received the participant information. It is done. In other words, when it is determined that a fire has occurred by the fire determination unit 120, a message in the form of SMS (hereinafter referred to as “SMS”) to the person in charge (hereinafter referred to as “participant”) located close to the electric pole where the fire occurred. Also referred to as "") is transmitted. At this time, the message is characterized in that it includes a URL including fire information for confirming an address of a fire occurrence point, a fire occurrence time, and a real-time video for confirming the fire occurrence site.

At this time, the message transmission unit 140 of the IoT platform server 1000 transmits a URL containing fire information until a participant who can be dispatched in the event of a fire occurs based on whether the participant responds to the transmitted message and whether it is received. Characterized in that. A detailed description of this will be described later.

The controller 150 may check whether the participant has access to the application, and determine that the participant is in a state in which it is impossible for the participant to go to the site when the message transmission unit 140 is not connected based on the time when the message is transmitted. Accordingly, the message transmission unit 140 may transmit a message to the next participant according to a predetermined priority.

According to another embodiment, even if the participant is connected to the application, if there is no response for a certain period of time, the control unit 150 determines that the participant is in a state in which it is impossible to go to the site, and sends the message to the next participant through the message transmission unit 140. You can send a message.

According to another embodiment, when the location of a participant who has transmitted a message including fire information for on-site dispatch using GPS is not within a preset location range, the control unit 150 is in a state in which the participant is unable to move to the site. It is determined that the message transmission unit 130 can transmit a message to the next participant. In other words, since the person in charge is designated for each area even within one area, a certain signal must be received for each person in charge, but if the person in charge is out of the designated location area, another signal is received, so that the participant is judged to be unable to go to the site. Meanwhile, the location of the person in charge (participant) can also be confirmed through Bluetooth or a beacon.

Referring to FIG. 3, the application server 200 includes a receiving unit 210, a display unit 220 and a transmitting unit 230.

The receiving unit 210 receives an SMS including fire information in the form of a URL transmitted from the IoT platform server 100. At this time, the SMS is basically received by the receiver 210 included in the application server 200 of the participant placed close to the fire occurrence point, but if the on-site response of the participant designated for the first on-site response is impossible It is characterized in that the SMS is delivered to the next participant by the transmission unit 230. When SMS is delivered, it is basically delivered based on a predetermined priority, and it is characterized in that it is delivered until a participant who approves the on-site response comes out.

The SMS is displayed on the display unit 220 of the participant's mobile device, as shown in Figs. 5A and 5B, and the participant can check the fire information through the display unit 220, and whether or not to be dispatched to the fire site is possible. You can answer.

Specifically, the participant who has received the SMS from the IoT platform server 100 responds to the request information for checking whether the site can be dispatched for quick response to the site through a user interface (UI). do. Since there may be cases where the personnel in charge closest to the point of fire may not be able to immediately dispatch due to circumstances, the initial response to the request information from the participant is performed by sending the request information on whether or not it is possible to dispatch to the participant. It can effectively improve the speed of response. Here, the response to the request information is characterized by being performed through a user interface (UI) such as an input button of a pop-up window or a messenger window.

For example, as shown in FIGS. 5A and 5B, when the participant selects the message 226 including the URL included in the SMS, “20:31 fire occurs, is it possible to go to the fire site?” The request information IN may be delivered through the pop-up window 225 together with a Yes/No button AN. In addition, as shown in FIG. 5B, a Yes/No button may be included in the message 227 and transmitted, and the participant may select a button (AN) to respond to the request information transmitted by the above two methods. have. Referring to FIG. 5A, as the URL is clicked, a web site of the “disaster disaster monitoring system” containing fire information on the site where the fire occurred is popped up. In the pop-up window 232, location information about the fire site (Bekdogan 278), fire date (2020-05-01), fire occurrence date and time (08:31 PM), real-time video, fire risk level, fire risk level. Characterized in that it includes numerical and meteorological data.

Specifically, referring to FIG. 5B, a message 226 including a URL including fire information received from the IoT platform server 100 is displayed on the display unit 220 in the form of a messenger window. Depending on the embodiment, the application server 200 may include a function of a chatbot (or chatbot) having a structure of "request-response". In this case, after the fire information is transmitted as text as shown in the dotted line message 227, the participant directly responds to the chat window 229 of the application when the request information 228 is transmitted to see if the fire site can be dispatched. After inputting, if the transmission button 230 is selected, an answer may be transmitted 231. At this time, the answer is that all expressions with the same meaning, such as Yes/Yes/Yes/OK/Okay, agree to the on-site dispatch, and all expressions with the same meaning, such as No/No/X/Can't, agree to the on-site dispatch. It can be judged as not.

In addition, according to another embodiment, the message including the request information 228 related to the fire information 227 transmitted in text form may further include a yes/no button. Accordingly, convenience can be increased by the participant performing an answer by selecting a button.

On the other hand, there may be a case where a participant who has received a message for on-site dispatch cannot be on-site. In this case, as shown in FIG. 6, a message is automatically delivered to the next participant according to a predetermined priority (ie, a short distance order from the fire occurrence point). In other words, if the participant who received the message replies that it is possible to go to the site, the message is sent only to the participant, but if the participant who received the message is answered that it is impossible to go to the site, it is sequentially until possible participants come out based on a predetermined priority. A URL containing fire information is delivered. Accordingly, referring to the map MA of FIG. 6, it can be seen that one area has five personnel assigned to each area. In more detail, assuming that on-site employees managed by one KEPCO branch are displayed by area on the map (MA), the on-site employees managed by one KEPCO branch are from the first area (A1) to the 5th area (A5). ), it can be seen that it is assigned to each area divided into 5 areas.

Here, the on-site staff must be on standby at all times for the occurrence of a fire, and in case of a fire, they must promptly answer whether dispatch is possible.However, because dispatches may be impossible due to circumstances, a message is sent to the next participants based on a predetermined priority. It is characterized by that. For example, when a fire occurs in the first area A1, the SMS is first transmitted to the application server 200 of the participant located in the first area A1. At this time, assuming that the participant in the first area (A1) answered that it is impossible to dispatch, the SMS is based on the predetermined priority, from the first area (A1) to the fourth area (A4), the fifth area (A5), and The second area A2 and the third area A3 may be delivered to users located in each area in the order. However, the predetermined priority may be based on a short distance, but depending on an embodiment, the participants with a fast response speed may be in the order of the participants, and the participants with a rapid on-site dispatch may be ordered based on the current traffic situation. That is, it may be changed based on items previously set by the user of the fire monitoring system 1000.

In addition, according to another embodiment, when a participant's response to the request information IN does not respond for a predetermined time or longer, the request information IN is automatically transmitted to the next participant according to a preset priority. . Even in this case, the priority is the same as described above.

7 is a flow chart showing a fire monitoring method according to an embodiment of the present invention.

7 is a method of monitoring a fire in a fire monitoring system 1000 including a plurality of application servers 200 connected through a mesh network and receiving data in one direction from the IoT platform server 100 and the IoT platform server 100 For the purpose of explaining, contents overlapping with the contents described in FIGS. 1 to 6 will be omitted.

First, participant information is received from the collection unit 130 of the IoT platform server (S100). Subsequently, based on the participant information, the security authentication link LI is transmitted to the plurality of application servers 200 through the message transmission unit 140 of the IoT platform server (S200). Subsequently, by monitoring the data collected from the flame detector and the meteorological data collector by the monitoring unit 110 of the IoT platform server in real time, it is determined whether a fire has occurred (S300). At this time, by comparing the flame data and meteorological data collected from the flame detector and the meteorological data collector by the fire determination unit 120 of the IoT platform server, it is possible to calculate a fire risk that can confirm the risk stage of the fire. Subsequently, the message transmission unit 140 of the IoT platform server transmits an SMS for requesting a site dispatch to the application server based on whether a fire has occurred (S400).

Here, the SMS is characterized by including a user interface for selecting whether or not a person responding to the site can be dispatched, and fire information including real-time images for confirming the address of the fire occurrence point, the fire occurrence time, and the fire occurrence site. . In addition, when the participant responds to the SMS for the on-site dispatch request that it is impossible, the SMS is characterized in that it is sequentially delivered to the next participant based on a predetermined priority.

In the conventional fire monitoring system, when the KEPCO server receives a danger signal from the fire area, the KEPCO branch employee checks it and requests a nearby site response personnel to mobilize the site. However, since the KEPCO server uses a closed network for security, there is a limitation of a one-way transmission method that transmits data to the outside using SMS. In other words, the closed network KEPCO server only transmits messages to the KEPCO branch office, and it is difficult to communicate with on-site staff in connection with on-site dispatch, which causes a serious situation in which the communication process is delayed in situations where on-site dispatch is impossible. .

In addition, since the received signal is updated every 10 minutes, if a fire occurs immediately after the update, an abnormal signal is already discovered after a certain period of time has elapsed at the branch of KEPCO. For this reason, if the on-site response is delayed even a little in the process of delivering the branch employee to the on-site employee, there is a problem that serious property damage or personal injury may be caused.

As described above, since the conventional fire monitoring system uses the one-way transmission method of KEPCO, the fire situation is shared only with participants who have requested to be dispatched to the site, so there is a limit to more rapid on-site response.

On the other hand, the fire monitoring system 1000 according to an embodiment of the present invention maximizes the on-site response speed by automatically notifying the possible on-site personnel in the vicinity of the fire-producing site by monitoring whether or not the fire has occurred in real time with a flame detector. There is an effect that can be done.

In addition, the fire monitoring system 1000 according to an embodiment of the present invention can effectively increase the speed of fire response without a separate server by notifying a plurality of applications connected through a mesh network via SMS even when working with a KEPCO server that is a closed network. There is an effect.

In addition, the fire monitoring system 1000 according to an embodiment of the present invention has an effect of preventing serious damage to humans or property damage in advance through rapid on-site response. That is, the present invention has an effect of preventing the spread of fire.
