A specific safety management method of the safety management system 1000 will be described in detail below.

3 is a flowchart illustrating a method for managing safety of urban facilities according to an embodiment of the present invention.

First, the main server 100 receives the state information of urban facilities in real time from the safety management device 200 installed in the urban facilities (S110).

As described above, each of the plurality of urban facilities may be equipped with the safety management device 200 . The safety management device 200 may generate state information of city facilities. The sensor unit 230 of the safety management device 200 detects information about the climate around city facilities, information about the ground on which city facilities are installed, the degree of impact applied to city facilities in real time, the degree of tilt of city facilities, etc. and may be generated, and information on aging of urban facilities may be stored in the storage unit 240 of the safety management device 200. If the safety management device 200 includes a photographing unit, the photographing unit may generate real-time images of city facilities.

The control unit 210 of the safety management device 200 controls information on the climate around urban facilities, information on the ground on which the urban facilities are installed, and aging of the urban facilities from the sensor unit 230, the storage unit 240, and the photographing unit. Information about the city, the degree of impact applied to the city facility in real time, the degree of tilt of the city facility, and the real-time image of the city facility can be received, and state information of the city facility can be generated using this information. The main server 100 may receive state information of the corresponding city facility from the safety management device 200 in real time.

Subsequently, the main server 100 transmits the state information of each of the plurality of urban facilities to the main display unit 110 in real time so that the state information of each of the plurality of urban facilities including the city facilities is displayed on the map on the main display unit 110. Do (S120). The main server 100 may receive state information from each of the plurality of safety management devices 200 installed in each of a plurality of urban facilities, and may generate a map on which the state information is displayed using the received plurality of state information. .

For example, the main server 100 may generate a 2D or 3D map, and display locations of a plurality of urban facilities as markers corresponding to locations on the map. In addition, state information of each displayed urban facility may be displayed together on a map. The main server 100 may transmit data to the main display unit 110 so that the main display unit 110 displays such a map, and the main display unit 110 displays a map displaying location and status information of a plurality of urban facilities, can be provided to the manager.

Subsequently, the main server 100 determines the risk level of the urban facilities by using the state information of the urban facilities (S130). The risk level may be a level indicating a degree to which the safety state of the corresponding urban facility becomes unsafe. For example, the risk level may include 5 levels of 1 to 5, and the highest level 1 may mean a dangerous state farthest from a safe state. And, the lowest grade 5 may mean the safest state closest to the safe state. In this way, when the risk level is divided into a total of 5 levels, level 5 means a safe state, level 4 means a state requiring management, level 3 means a warning state, level 2 means a dangerous state, and level 1 means an emergency state.

The main server 100 may receive state information of the corresponding urban facility from the plurality of safety management devices 200 mounted on each of the plurality of urban facilities, and determine the risk level of each of the plurality of urban facilities by using the state information. can At this time, in determining the risk level, the main server 100 may calculate a predetermined score for the city facility and determine the risk level of the city facility based on the predetermined score.

Specifically, the predetermined score may be determined by the following equation including variables for each of the climate around the urban facilities, the ground on which the urban facilities are installed, the degree of deterioration of the urban facilities, and the real-time state of the urban facilities.

Equation) P = A * x + B * y + C * z + D * r

In the above formula, P means a predetermined score, A * x means a variable for the climate around the urban facility, B * y means a variable for the ground on which the city facility is installed, and C * z is the value of the urban facility It means a variable about the degree of deterioration, and D * r can mean a variable about the real-time state of urban facilities. Therefore, P, which means a predetermined score, is a variable for the climate around the urban facility (A * x), a variable for the ground on which the urban facility is installed (B * y), and a variable for the degree of deterioration of the urban facility (C * z) and the variable (D * r) for the real-time state of urban facilities.

Specifically, in the variable (A * x) for the climate around urban facilities, x may be a value representing the climate around the urban facilities, for example, precipitation per hour, wind strength, etc., and A is the climate value for x. may be a weight for

And, in the variable (B * y) for the ground where urban facilities are installed, y is a value representing the degree of danger of the ground where urban facilities are installed. It may be a value indicating the degree of tilt of the ground, the degree of vibration applied to the ground when an earthquake or the like occurs. And, B may be a weight for y, which is a value for the ground.

In addition, in the variable (C * z) for the degree of deterioration of urban facilities, z is a value for the degree of deterioration of urban facilities, the period from the installation of urban facilities to the point of risk rating calculation, and the repair history of urban facilities , it may be a value indicating a result value when the safety state of urban facilities is checked. And, C may be a weight for z, which is a value for aging.

And, in the variable (D * r) for the real-time state of urban facilities, r is a value for the real-time safety state of urban facilities, the angle of inclination based on the axis perpendicular to the sea level of the city facility, and transmitted to the city facility in real time. It may be a value indicating the intensity of the impact, the degree of risk of the urban facility calculated based on the real-time image of the urban facility, and the like. And, D may be a weight for r, which is a value for the real-time safety state of urban facilities.

In this case, the sum (A+B+C+D) of all weights A, B, C, and D for each of the variables x, y, z, and r may be 1. However, it is not limited thereto, and the sum of all weights A, B, C, and D (A+B+C+D) may be less than or greater than 1, which may be changed by the manager of the main server 100.

The weight A for x, the weight B for y, the weight C for z, and the weight D for r will be described in detail. The weights A, B, C, and D can be changed under various conditions.

Specifically, each of the weights A and B may be changed according to a value z for the degree of deterioration of urban facilities. For example, the value z for the degree of obsolescence and the weights A and B, respectively, may have a proportional relationship. That is, when the value z for the degree of deterioration of urban facilities increases, the weight A and the weight B increase, resulting in the reflection ratio of x, the value for the climate around the urban facility, and y, the value for the degree of danger of the ground on which the urban facility is installed. The reflection ratio of can be increased. Conversely, when the value z for the degree of deterioration of urban facilities decreases, the weight A and B decrease, resulting in the reflection ratio of x, the value of the climate around the urban facility, and y, the value of the degree of danger of the ground on which the urban facility is installed. The reflection ratio of can be reduced. This may be a condition considering that as the degree of deterioration of urban facilities increases, they may be more affected by the climate around the urban facilities or the degree of risk of the ground on which the urban facilities are installed.

In addition, the weight D may be changed by x, which is a value for the climate around the urban facility. For example, a value x and a weight D for the climate surrounding an urban facility may have a proportional relationship. That is, when x, the risk value for the climate around urban facilities, increases, the weight D may also increase, so that the reflection rate of r, which is a value for the real-time safety state of urban facilities, may increase. Conversely, when x, the risk value for the climate around urban facilities, decreases, the weight D is also reduced, so that the reflection ratio of r, which is a value for the real-time safety state of urban facilities, may decrease. This may be a condition considering that when the climatic conditions around urban facilities, such as earthquakes and precipitation, become poor, the possibility that the urban facilities may tilt due to the climatic conditions or an impact on the urban facilities may increase. .

The main server 100 may calculate a predetermined score for a city facility by the above formula, and may assign a higher risk grade when the predetermined score is higher. The numerical value of the predetermined score dividing the first to fifth grades may be set by the manager of the main server 100 .

Subsequently, the main server 100 transmits information on the risk level to the main display unit 110 so that the risk level is displayed on the map on the main display unit 110 (S140). The main server 100 may calculate a risk level for each of a plurality of urban facilities, and transmit related information to the main display unit 110 so that the main display unit 110 displays information on the risk level on the map. . The main display unit 110 may display marks of a plurality of urban facilities at corresponding locations on a map so that a manager can easily identify the locations of the plurality of urban facilities. In addition, the main display unit 110 may display the risk level of the corresponding urban facility adjacent to the mark of the city facility displayed on the map. The risk level may be displayed in various ways, and for example, the risk level may be displayed in the form of numbers. Alternatively, the risk level may be displayed with light sources of different colors corresponding to each level. For example, level 5, which is the lowest risk level, is a green light source, level 4, which requires management, is a yellow light source, level 3, a warning level, is an orange light source, and level 2, a dangerous state, is a red light source. As a light source of, emergency level 1 can be displayed on the map as a light source that flickers at regular intervals.

Next, when the main server 100 needs to take action on the city facilities based on the risk level, it transmits information on the state of the city facilities and the risk level to the external server (S150).

The main server 100 can check the risk level of each of the plurality of urban facilities in real time, and when the risk level changes, it can take necessary measures for the corresponding urban facility. For example, when the level of urban facilities is changed from level 5, which is a safe state, to level 4, which requires management, the main server 100 has safety assigned to the city facility so that a safety manager can be directly dispatched to the city facility. The manager's terminal, can deliver information about the state of the city facility and the risk level.

For another example, the main server 100 is an external server operated by a fire department, police station, local government, etc., when the grade of an urban facility is changed to a dangerous grade 2 or an emergency grade 1, and the state information of the corresponding city facility. and information on the risk level can be delivered. The main server 100 can deliver status information, such as specific risk conditions of first-class or second-class urban facilities and real-time captured images, to situation solving organizations such as fire departments, police stations, and local governments, and thus, immediate damage caused by urban facilities. can reduce

According to an embodiment, when the urban facility is in a repair state, the main server may transmit a signal to the main display unit so that the repair state of the urban facility can be displayed on a map displayed by the main display unit. Specifically, repairs may be made to a specific urban facility among a plurality of urban facilities. A manager who directly visits an urban facility may input a repair start state to a safety management device installed in the urban facility, and the safety management device may transmit a signal that repair has started to the corresponding city facility to the main server.

The main server transmits information on the repair status to the main display unit so that a mark indicating the repair status (for example, a triangle mark) can be displayed adjacent to the mark of the corresponding urban facility where repair has started on the map displayed by the main display unit. can Accordingly, the manager of the safety management system can easily check urban facilities that have been repaired and are in a state of repair on the map displayed on the main display unit.

According to an embodiment, the main server may transmit information about the repair level to the main display unit so that the repair level of urban facilities in a repair state is displayed on a map. Specifically, urban facilities may be repaired, and a safety management device installed in the urban facility where repair has started may transmit the degree of repair of the urban facility to the main server in real time. For example, the safety management device may receive information about the start time of repair and the time required for repair from a manager directly performing the repair. In this case, the safety management device may calculate the degree of repair by using the repair start time and the time required for repair. The safety management device may calculate that 50% of the repair has been completed at 14:00 when the repair started at 13:00 and the time required for the repair is input as 2 hours. As another example, the safety management device may receive an input of the degree of repair from a manager directly performing the repair. If there are 4 steps required for repair, the manager can input the progress of the repair to the safety management device according to the progress of the repair steps, and the safety management device determines the degree of repair based on the entered repair progress. can be calculated.

The safety management device may transmit information on the degree of repair to the main server in real time, and the main server may display the degree of repair on the main display unit as well. The main display unit is adjacent to the mark of the urban facility being repaired on the map and shows the degree of repair, for example, in percent (%), or a long bar is filled in according to the degree of repair on the map. can be displayed

According to an embodiment, when the urban facility is in a repair state, the main server may determine the repair priority of the urban facility based on the risk level of the urban facility.

Specifically, a plurality of urban facilities may have respective risk levels. Some of the plurality of urban facilities may be in a state of repair, and corresponding urban facilities in a state of repair may have respective risk levels. Urban facilities in a state of repair may be prioritized for repair based on a risk level of each of the urban facilities. Among urban facilities in a state of repair, urban facilities with a high risk level may have a high repair priority, and among urban facilities in a state of repair, urban facilities with a low risk level may have a low priority for repair. If the risk level is high, the repair priority is also high, so that urban facilities with a high risk level can be repaired more quickly.

According to an embodiment, as the repair of urban facilities in a state of repair is performed, the risk level of the urban facilities may be lowered. For example, when a grade 1 urban facility is in a state of repair, the risk grade of grade 1 may be lowered to a grade 2 or 3 as the repair progresses. The risk level (for example, level 1) of urban facilities in a state where repairs are started may be lowered to level 5 when all repairs are completed. In this case, the risk level of the urban facility may be changed in response to the degree of repair of the urban facility. That is, when repairs are started (the degree of repair is 0%), the risk level of urban facilities may be Grade 1, and when the repair is completed by 1/4 (the degree of repair is 25%), the risk grade of urban facilities is Grade 2. , and if the repair is 1/2 progress (the degree of repair is 50%), the risk level of the urban facility may be 3, and if the repair is carried out 3/4 (the degree of repair is 75%), the risk of the city facility The grade may be grade 4, and when the repair is completed (the degree of repair is 100%), the risk grade of the urban facility may be grade 5 (safe state).

In this case, when the risk level is changed according to the degree of repair, the repair priority of the corresponding urban facility may be changed as the risk level is changed. That is, an urban facility, which had a high risk level and a high priority for repair when the repair was started, may have a lower risk level as the repair progresses and the priority of the repair may be changed to a lower priority. In this way, as the degree of repair increases, the risk level of urban facilities decreases, and the priority of repair of urban facilities may decrease corresponding to the degree of repair and risk level. Accordingly, a repair priority may be selected by reflecting both the degree of repair and the risk level.

According to one embodiment, the main server may transmit a signal notifying the safety management device of state information of urban facilities to the safety management device based on the risk level. A signal for notifying the state information of urban facilities is a signal for notifying the state information of urban facilities to the surroundings of the urban facilities, and may be a signal capable of notifying the dangerous state of the urban facilities to pedestrians and drivers near the urban facilities.

Specifically, the safety management device may further include at least one of a display unit and a beam projector in addition to the components shown in FIG. 2 . The display unit of the safety management device is an electronic device such as an electronic display board installed in city facilities, and may be configured to display desired information. In addition, the beam projector may be configured to project light onto an area adjacent to city facilities, for example, a ground area adjacent to city facilities, and display various texts, pictures, and the like in the area adjacent to the city facilities.

The main server may transmit a signal for notifying state information of urban facilities to a safety management device when the risk level is higher than a specific risk level, for example, when the risk level is higher than or equal to the second level. Correspondingly, the safety management device may display status information on the display unit or make the beam projector display status information in an area adjacent to the urban facility.

When the risk level of urban facilities increases, the main server may transmit a signal notifying state information of increased visibility to the safety management device. The status information with increased visibility may refer to status information in which the size of the status information being displayed is increased, displayed in a more conspicuous color, or displayed in a flickering manner at regular intervals. For example, when the risk level of urban facilities is 2, the display unit of the safety management device may display state information or the beam projector may project the state information to an adjacent area according to a signal notified by the main server. In addition, when the risk level of urban facilities increases from grade 2 to grade 1, the main server may transmit a signal notifying the state information of increased visibility to the safety management device. Correspondingly, the display unit of the safety management device may display state information with increased visibility than previously displayed state information, or the beam projector may project state information with increased visibility to an adjacent area.

According to an embodiment, the beam projector may increase the range of an adjacent area onto which state information is projected in a direction spaced apart from the urban facility when the risk level of the urban facility increases. When the risk level increases, the beam projector projects the status information from the area where the status information was previously projected (for example, the ground area surrounding the city facility) to the passage area adjacent to the city facility that can enter the city facility. area can be enlarged. As the status information, which was projected only in the area extremely close to the urban facilities surrounding the urban facility, is projected to the passage of the adjacent alley accessible to the city facility as the risk level increases, pedestrians, drivers, etc. It can effectively reduce the possibility of access.
