Description

Bridge disaster management system in consideration of deterioration degree {MANAGEMENT SYSTEM FOR DISASTER OCCURRENCE OF BRIDGE CONSIDERING DETERIORATION}

The present invention relates to a bridge disaster management system, and more particularly, a single disaster caused by individual disaster factors such as strong wind, earthquake, snowfall, etc., which causes a bridge disaster, a composite disaster in which multiple disaster factors work in combination, and one In determining the impact of a disaster on bridges by various disasters, such as interlocking disasters that trigger other disasters, the bridge is considered in consideration of not only the type of disaster but also the degree of deterioration of each bridge and the degree of disaster accumulated in each bridge. After calculating the disaster situation to be experienced directly, the scenario that can respond to the calculated disaster situation is extracted and transmitted to the bridge manager or the public around the bridge to the communication network, etc. The bridge disaster management system considering the degree.

Recently, due to industrial development and urban expansion, construction of various structures such as bridges, tunnels, high-speed railways, dams, and high-rise buildings has been actively performed, and abnormal displacements such as deformation, cracking, collapse, and leakage of various structures are thereby achieved. B. Increasingly, cases of damage by the public are increasing due to natural disasters such as aging, typhoons, and floods.

In Korea, we have also experienced disasters caused by the deterioration of structures, such as the collapse of Sampoong Department Store and Seongsu Bridge. Therefore, the desire to protect their safety from the damage case is increasing, and even if the damage is not devised, a method for continuously checking the safety of various structures is being devised.

In general, a variety of measuring instruments, such as accelerometers, sag meters, inclinometers, strain gauges, thermometers, wind directions, are used to determine if there is an abnormality in large structures such as bridges, tunnels, high-speed railways, dams and tall buildings. • Anemometer, seismograph, etc. are used, and the data measured from each measuring instrument are made into a database and used as basic data for determining the abnormality of various structures.

However, even in the case of such a structure, especially a bridge, if there is an abnormality by using various equipments, if the disaster such as a strong wind, an earthquake, or snowfall occurs, it is possible to accurately grasp the extent of the disaster that the structure suffers in the event of a disaster. Frequently, it is difficult to do so, which causes frequent loss of structures such as bridges, and unexpected damages to citizens who have vaguely trusted the robustness of such structures and used them as usual.

Therefore, in the case of such a structure, especially a bridge, it is important to provide information about disasters such as strong winds, heavy rain, earthquakes, or snowfall, even though it is most important to quickly determine the disaster situation that can quickly determine the degree of disaster that the structure is experiencing. Relying only on weather information, there was a problem that it is difficult to respond quickly.

In addition, weather information is only a simple forecast. In recent years, when weather events occur frequently due to abnormal weather such as heavy rainfall or heavy snowfall, local disasters are terminated after each disaster. It is not practically helpful to the residents who directly experience the weather phenomenon caused by such abnormal weather, such as news indicating that the response is insufficient.

Therefore, even if the quick judgment on the disaster situation is an impediment to prevent further damage, attempts have not been made actively. In addition, even though the disasters occurring in each region are different, there is a problem that proper disaster determination and rapid response cannot be made because the regional differences and in particular, the structures are not considered to be seasonally weak.

In addition, in the case of a bridge with a lot of traffic, if the judgment of the disaster situation is delayed, it will lead to a catastrophic disaster. However, due to human limitations, it may take a long time to accurately grasp all situations. This is a very big problem in estimating the direction and scale of necessary measures such as securing recovery relief items or input of recovery relief equipment in accordance with rapid situation identification.

The most important thing in identifying a disaster is information about the location or object where the disaster occurred. In the event of a quick and accurate identification of the location or structure of a disaster, the response to the disaster can be made quickly, and even when the magnitude of the disaster is not quickly communicated, the dispatch of disaster management personnel to the site is quick. This allows for quick follow-up.

However, the reporting system of the disaster situation up to now has been focused on collecting and storing it centrally through voice and document report through the telephone or fax of the victim, and then analyzing it through statistics. However, the reality is that the judgment on this depends entirely on human judgment.

As a result, it is possible to determine the types and types of disasters occurring more quickly, and to appropriately deal with the disasters that the structures have to suffer according to the seasons of each region, and to consider the degree of deterioration of the damaged structures due to the lapse of the manufacturing period. There is still a need for a new disaster management system that goes beyond abstract disaster determination, such as forecasting, to quickly assess and take action on the actual degree of disaster that the structure, in particular the bridge, will be experiencing.

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

1 is a block diagram of a bridge disaster management system considering the degree of deterioration according to the present invention.

Referring to Figure 1, the bridge disaster management system in consideration of the degree of deterioration according to the present invention, to obtain the environmental information of the bridge to measure the individual disaster factors affecting the structure, such as bridges and a plurality of transmission through the wired and wireless communication network Disaster factor measurement module 100 consisting of sensors and the environmental information around the bridge obtained from a plurality of sensors constituting the disaster factor measurement module by collecting the disaster factor and the type of disaster from the combination of the extracted disaster factor Disaster type determination server 200 and judging by the disaster factor measurement module, and the bridge status information based on the seasonal characteristics of the area where the bridge is installed and the time when the disaster factors are extracted and continuously updated and stored Bridge deterioration management server 300 for storing the data of the degree of deterioration of the bridge and repetitive in the area where the bridge is installed In the region and season in which the disaster type and the bridges are determined based on the accumulated disaster information management server 400 for storing the accumulated disaster information on the bridges and the disasters accumulated in the bridges as cumulative disaster information. Based on the degree of deterioration of the bridge and the cumulative disaster information applied to the bridge repeatedly, the disaster situation to be applied to the bridge by the current disaster factor is calculated, and then the corresponding scenario set according to the calculated disaster situation is extracted It is configured to include a bridge disaster management server 500 for sending out an alarm.

The disaster factor measurement module 100 is composed of a plurality of sensors for obtaining environmental information around the bridge installed in each area to determine whether a disaster occurs in the structure, such as a bridge. Accordingly, the disaster factor measurement module 100 is fog, snow, ice, strong wind, earthquake around the structure. It is preferable that the sensor group is provided with a sensor group capable of providing weather information such as tsunamis, lightning strikes and heavy rains, or natural phenomena applied to the structure or state information on artificial disasters such as fire, traffic accidents, structure destruction, terrorism, and the like. At this time, the term "bridge" in this specification does not simply mean a bridge, but is used to mean including various structures installed in each region.

As described above, in order to obtain various environmental information around the bridge, the disaster factor measuring module 100 includes various types such as wind direction, wind speed sensor, precipitation sensor, temperature humidity sensor, road surface sensor, fog sensor, snow sensor, and earthquake sensor. It is configured to include a sensor, in addition, it is preferable to further comprise a variety of sensor groups for measuring the factors causing climate change or natural disaster that may affect the bridge.

Hereinafter, the sensors constituting the disaster factor measurement module 100 will be described. However, the sensors are not limited to some of these sensors, and each of the sensors is not limited to the details described below, but also various other types. Of course it can.

The wind direction wind speed sensor is provided to prevent the overturning of a large vehicle by observing the occurrence of gusts or the like around the road or the bridge, the measurement range of the wind direction wind speed sensor is 0 ~ 365 °, wind speed 0 ~ 60m / s, the maximum surviving wind speed is 100 m / s, the accuracy is ± 3 ° wind direction and ± 0.3 m / s wind speed can be used.

In addition, the precipitation sensor is measured by using a contact circuit configuration impedance detection method, and is used to measure the amount of precipitation that falls in a certain section of the specific area (region) in which the structure exists.

The temperature and humidity sensor is a basic element of the road condition, the measuring range is -50 ℃ ~ +60 ℃ temperature, 0 ~ 100% humidity, accuracy is ± 2 ℃, humidity is ± 2% . In addition, the temperature and humidity sensor may use a shield (simple white) ventilation type.

The fog sensor is a sensor for measuring the visible distance, density, rainfall, snowfall due to the fog of the road. Here, the fog sensor is measured by the back scattering (back scattering) method, it is installed at a height of 4 ~ 6m outside the road. The operation principle is to detect a scattered electrical signal of the fog particles passing through the detection unit by firing a laser, the electrical signal changes according to the amount of the detected fog, and calculates the calculated visible distance using the changed electrical signal. On the other hand, the fog sensor calculates the amount of each observation by observing the visible distance, density, rainfall, snowfall, fog, size of the raindrops, speed, etc., especially in the case of localized heavy rain, and can also determine the type of rain In addition, maintenance costs are low and management can be facilitated.

The road surface sensor is a sensor for measuring the state of the road surface, the snow amount sensor is measured by using a tipping bucket type (tipping bucket type) for 1 pulse per 0.5mm of rainfall, 1 ~ 100㎜ / 1hour ± 1 Has a precision of%. Here, the road surface sensor is measured in a non-contact double method, it is installed in the tower of the height of 4 ~ 6m on the outside of the road. The operation principle transmits an infrared laser to receive a reflection value reflected from the road surface, converts the received reflectance into an electrical signal value, and measures the road surface state using the converted voltage value. On the other hand, by not embedding the road surface sensor on the road, the installation and operation is simple, and the maintenance cost can be reduced and easy to manage. The road sensor is designed to operate at -40 ° C to + 60 ° C.

The seismic sensor may be configured to include a variety of vibration measuring unit including an acceleration sensor.

The disaster type determination server 200 receives a measurement value transmitted from the sensors of each region constituting the disaster factor measurement module through a wired / wireless communication network, and is determined in advance that the measured values of the received sensors will affect the bridge. In case of exceeding the range, the disaster factor collection unit 210 storing the disaster factor for the area and the measured value determined as the disaster factor in the disaster factor collection unit are applied to the bridge installed in the area. The disaster is a single disaster judgment unit 220 that judges the disaster as a single disaster, and when the measured value determined as the disaster factor in the disaster factor collection unit is two or more in the same area, the disaster applied to the bridge installed in the area as a composite disaster. The composite disaster determination unit 230 to determine, and the measured value determined as a disaster factor in the disaster factor collection unit is two or more in the same area and the two or more If the disaster factor is a continuous disaster factor triggered after the occurrence of one disaster factor is configured to include an interlocked disaster determination unit 240 to determine the interlocked disaster.

At this time, the disaster factor collection unit 210 measures the value indicating the environmental information (wind speed, precipitation, temperature, road surface conditions, fog, snowfall, earthquake, etc.) around the bridge transmitted from the disaster factor measurement module 100 It is preferable to be configured to receive the data via a wired or wireless communication network in real time and store it in a database.

The disaster factor collection unit 210 compares the measured value stored in the database with a preset range of reference values, that is, a range of poor environmental information that can be determined as a disaster, and the measured value is preset. If the threshold is exceeded, it is configured to determine that a disaster factor has occurred in the area.

At this time, the range of the reference value for determining the disaster factor can be set in various ways in consideration of the regional characteristics of the bridge is installed, the administrator can also change the range of the reference value according to the season.

In other words, in the case of bridges installed in areas with high flow rates and rapid changes in flow rate, the range of reference values for precipitation is reduced, and for bridges installed in areas with weak ground, the range of reference values for earthquake vibration is reduced. It is desirable to be configured so that various settings can be made according to the characteristics of the region.

As such, when there is only one disaster factor determined in the disaster factor collection unit 210 in one region, the single disaster determination unit 220 determines the disaster applied to the corresponding bridge as a single disaster, and the disaster factor is one When two or more overlap in an area, the composite disaster determination unit 230 determines that the disaster applied to the bridge is a composite disaster. In this case, whether or not the area where the disaster factors overlap is one area is to determine whether or not the disasters applied to the bridge overlap, it is preferable to determine based on the installation location of the bridge.

To this end, the disaster factor collection unit 210 is preferably configured to receive and store the measured value transmitted from the disaster factor measurement module 200 with a unique identification number of each region.

In addition, when there are two or more overlapping disaster factors in a region, the interlocked disaster determination unit 240 determines the type of the disaster factor, and if there is a disaster factor triggered by the cause after the occurrence of one disaster factor, the interlocked disaster Will be judged.

As described above, when it is determined that two or more disaster factors overlap in one bridge in the composite disaster determination unit 230 or the interlocked disaster determination unit 240, the impact on the bridge is greater than that of a single disaster. Therefore, it is preferable that the bridge disaster management server 500 is configured to give a large weight during the disaster situation calculation so that it can be recognized as more emergency disaster situation.

The bridge degradation management server 300 stores a list of structures, such as bridges installed in each region by region, and a bridge management unit 310 for each region for integrated management of the deterioration degree of each structure by region, and each structure repeatedly each season. It includes a seasonal bridge management unit 320 for integrated management of the disasters and the resulting degradation of each structure by seasons, and a degradation modeling unit 330 for modeling and managing the degree of degradation of each structure.

At this time, the regional bridge management unit 310 stores the same structure as the bridge installed in each region for each region that can be affected by similar environmental information, wind speed, precipitation, temperature, road surface conditions, snowfall, earthquake experienced by each region It is configured to manage the overall degree of deterioration by integrating the effects of disaster factors such as Accordingly, the structure of the bridge, such as a bridge installed in the area after the typhoon has been applied to the same effect by the strong wind and precipitation, so that the overall deterioration state is updated and stored to manage the degree of degradation of the bridge.

In addition, the bridge management unit 310 for each region is commonly applied to the characteristics of the region in the case of the structure installed in the area such as the shore or mountain foot, that is, the degree of deterioration due to air or waves containing salt in the case of the structure installed on the coast In the case of the structure installed at the foot of the mountain, by applying the degree of deterioration due to rapids or landslides due to heavy rain in common, the regional characteristics of the structure installed can be considered in determining the degree of deterioration of the structure.

In addition, the regional characteristics are managed by the regional bridge management unit 310 can be considered steadily in determining the type of disaster that the current bridges, etc., or to calculate the disaster situation can be more quickly determine the actual disaster situation.

The seasonal bridge management unit 320 is cumulative management of the type of damage and damage caused by each season and the resulting deterioration of each structure, so that in preparation for the occurrence of disaster in advance in consideration of the disaster that is expected to be repeated again in the season. do. In addition, it is possible to predict a disaster that can be continued in the future considering the current season, even if the bridge determines the current disaster situation, so that it is possible to cope more quickly in an urgent situation such as a compound disaster or a linked disaster.

Unlike the regional bridge management unit 310 or the seasonal bridge management unit 320 that manages a plurality of structures by region or by season, the degradation modeling unit 330 continuously manages the individual deterioration degree of each structure itself. It is possible to manage the degree of deterioration by accumulating and storing the damage of each structure by the time of installation and the damage caused by the individual natural or artificial disasters that the structure directly suffered.

To this end, the deterioration modeling unit 330 generates a network model for each bridge for causality connecting the resulting deterioration triggering events experienced by the bridge for each bridge, and then deterioration triggering event occurs in each bridge. It is preferable to be configured to manage the degree of degradation of each bridge by updating the degree of degradation of the bridge by individually calculating the degree of degradation accordingly.

In this case, as a means for modeling the deterioration degree of each structure such as a bridge in the deterioration modeling unit 330, a failure mode caused by a combination of event tree analysis and element destruction representing a causal relationship is used. Proof of fault tree analysis, Markov Chain with extreme distribution of Markov Model, f (x), in which future modifications can be minimized by random processes where the future process is determined only by the current state. Markov Chain Monte Carlo Method (MCMC), which generates random numbers and simulates Monte-Carlo, Markov Chain alternately samples different sets of input variables, and improves the Metropolis method Reversible Jump MCMC, which allows input of discrete and continuous data. There are a variety of tools that are commonly used for modeling deterioration, such as Bayesian Belief Networks (BBNs), which can accurately correlate correlations. It is possible to be done.

The cumulative disaster information management server 400 is a regional disaster information management unit 410 for accumulating and storing the disaster information experienced by each region so that the impact of the cumulative disaster information can be considered in calculating the current disaster situation; It is configured to include a damage bridge management unit 420 to store the repair situation of the bridge that was directly damaged by the past disaster for each bridge to predict the damage caused by the additional disaster.

At this time, the regional disaster information management unit 410, such as the typhoon damage suffered continuously in recent years, to reflect the impact of repeated disasters in the same area to determine the degree of danger of the current disaster, during the past disasters It is desirable to store recent disasters that are not sufficiently resolved as cumulative disaster information so that they can be used as data for disaster situation calculations in the bridge disaster management server 500.

The bridge disaster management server 500 estimates the degree of damage to the bridge based on the disaster type determined by the disaster type determination server based on the surrounding environment information of the bridge transmitted from the disaster factor measurement module, and sets the grade of the disaster situation. And a disaster criterion database 510 for generating and storing corresponding scenarios of managers and citizens suitable for each disaster situation in advance, and the disaster type determined by the disaster type determination server and the degree of degradation stored in the bridge degradation management server. And a disaster situation calculator 520 that calculates a grade of a disaster situation to be applied to the bridge based on the accumulated disaster information stored in the cumulative disaster information management server, and a disaster situation grade of each bridge determined by the disaster situation calculator. Corresponding scenario extracting unit 530 which extracts a corresponding correspondence scenario from the disaster criterion database. And converting the corresponding scenarios and the grades of the disaster situation extracted into the form of a message, and then transmitting the alarms by transmitting them to the communication terminals of the administrators or residents in the vicinity of the bridge using a wired / wireless communication network. It is configured to include an alarm sending unit 540.

In this case, the disaster criteria database 510 may simply be configured to store only disaster types such as single disasters, complex disasters, or interlocked disasters, and to store corresponding scenarios for each type of disaster, but may be configured to have a structure in which structures such as bridges are installed. Depending on the characteristics, the type of the structure, the installation period, and the type and frequency of other recently accumulated disasters, the degree of endurance can be different. In order to recognize the higher level disaster situation and the newly installed structure as the lower level disaster situation, set the class of the disaster situation reflecting the above-mentioned matters, and then respond to the appropriate situation for each class of disaster situation. Is preferably configured to match and store the class of each disaster situation.

In addition, the corresponding scenario stored in the disaster reference database 510 is preferably configured to set and store specific response scenarios such as an emergency shelter or an alternative road for each structure in consideration of the characteristics of the area in which the structures such as bridges are installed. .

The disaster situation calculator 520 calculates a grade of the disaster situation that the structure will actually suffer based on the type of disaster applied to each structure, the degree of deterioration of the structure, and the accumulated disaster information accumulated in the structure. Higher levels are imposed on composite or interlocked disasters than disasters, and the higher the degree of deterioration, the less resistance to disasters is to be impaired. It is configured to calculate the overall degree of disaster as it is charged.

At this time, due to the seasonal nature of the summer when the damage from heavy rain, rainy season and typhoon is concentrated for one to three months, the ground is inevitably weakened during the relevant period. In the winter, the load supporting heavy snow is inevitably increased.In winter, the weight of the disaster is greater than the type of disaster or the cumulative disaster information. It is preferably configured to calculate the disaster situation by weighting at least one item among the disaster type, deterioration degree, or cumulative disaster information in consideration of seasonal characteristics such as determining the grade of the situation.

In addition, when it is determined that the recent disasters that have been repeatedly applied by the cumulative disaster information are the same, since the damages caused by the previous disasters are not recovered, the same disasters may be experienced. If the type of disaster determined in step S is identical to the recent disaster information transmitted from the cumulative disaster information management server 400, it is preferable to impose a greater weight on the cumulative disaster information to calculate the disaster situation.

As such, the response scenario that can appropriately cope with the grade of the disaster situation determined by the bridge disaster management server 500 is immediately transmitted to the manager who is set in advance or to the residents around the structure, so that a quick and proactive response to the disaster is achieved. It will be possible to prevent large damage.

In addition, the bridge disaster management server 500 can more quickly and accurately predict the disaster situation based on the current state of the structure and the past cumulative disaster information as well as the current disaster.

Next, the present invention will be described with reference to FIGS. 2 to 6, which show an actual implementation of the bridge disaster management system considering the degree of deterioration according to the present invention configured as described above.

Figure 2 shows the main screen of the bridge disaster management system according to the present invention, which is part of the gist of the present invention, is basically one of the individual disaster factors affecting the bridge, that is, the wind disaster This is an example to show the procedure corresponding to the occurrence.

3 is a screen of a bridge disaster management server 500 corresponding to a factor of 'strong wind' as a factor influencing the bridge, and according to the risk level of the strong wind according to the individual disaster factors of the strong wind, Correspondence manual is shown to match, the management department instructs in real time to carry out the entire emergency work, the corresponding action is "traffic front control". Of course, if the earthquakes acting as multiple disaster factors occur at the same time, how will two factors, "strong wind" and "earthquake," affect the bridge in parallel, and what should be done? It will be extracted into the response scenario according to the disaster situation stored in the disaster criteria database 510 and can perform the procedure accordingly.

FIG. 4 is a diagram illustrating a process of obtaining a corresponding action from the bridge disaster management server 500 when the grade of “strong wind” in FIG. 3 is determined in four steps. Responses are automatically made according to the current weather conditions, and the corresponding measures (weather weather information, measurement wind speed inspection, traffic front control, route patrol instruction, structure abnormality response instruction, etc.) are variously applied to the terminal of each department. Will be sent.

FIG. 5 is a diagram illustrating an example of a strong wind status report transmitted to the department in charge of response to a disaster occurrence status in the event of a “strong wind” in FIGS. 2 and 3.

FIG. 6 is a schematic diagram of the information system regarding the start time, end time, processing stage, and processing personnel of the business process to be performed when the "strong wind phase 2" occurs. FIG. It is implemented to see the response status in real time.

Bridge disaster management system according to the present invention shown in Figures 2 to 6 has shown to implement a 1: 1 response to how the disaster situation of "strong wind" affects the bridge, as described above, but actually the bridge In addition to the single disaster caused by an individual disaster factor called "strong wind", a number of complex factors such as strong wind and heavy snow, strong wind and earthquake may occur. .

Therefore, in the present invention, it is possible to reliably analyze the effects of such complex weather conditions, and present a dominant response scenario of a composite disaster in which two or more individual disaster factors act on the bridge.

In addition, in a bridge, one disaster factor triggers another disaster factor such as a traffic accident or a structure breakdown caused by a fire, and thus a continuous interlocking disaster may occur. By analyzing, it is possible to present the dominant response scenario of interlocking disasters affecting the bridge by two or more successive disaster factors.

While the present invention has been described in connection with what is presently considered to be the most practical and preferred embodiment, it is to be understood that the invention is not limited to the disclosed embodiments. Anyone with ordinary knowledge in the technical field to which the present invention belongs may make various modifications and imitations without departing from the scope of the technical idea of the present invention.
