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

The detailed description, which will be given below with reference to the accompanying drawings, is intended to explain exemplary embodiments of the present invention and is not intended to represent the only embodiments in which the present invention may be practiced.

In the drawings, parts irrelevant to the description may be omitted, and the same reference numerals may be used for the same or similar elements throughout the specification.

In an embodiment of the present invention, the expression “at least one” may indicate one of the words listed together or a combination of two or more.

For example, "at least one of A and B" may include only one of A or B, and may include both A and B.

1 illustrates a configuration of a shipyard safety management system according to an embodiment of the present invention.

Referring to Figure 1, the shipyard safety management system of the present invention safety management control unit 100, weather information collection unit 200, day job information collection unit 300, dangerous area information collection unit 400, accident probability calculation The unit 500, the worker terminal 600 and the work manager terminal 700 may be included.

The weather information collecting unit 200 may collect weather information.

The weather information may include at least one of outdoor temperature, indoor temperature, wind speed, wind direction, wave height, wave frequency, noise, vibration, and rainfall.

By collecting information on the current weather situation in real time, the current weather information can be continuously stored in the weather information storage unit (220 of FIG. 2) by time zone.

Current weather information, stored for a long time, is itself data that can verify the accuracy of future weather forecasts.

Based on the weather information on the current weather conditions, it is possible to make future weather forecasts by combining the forecasts received through the weather forecasts of various institutions.

In addition, the weather forecast of an institution can also provide statistics based on accumulated weather information.

These statistics can be used to predict weather with higher probability.

In addition, such weather information may be continuously updated.

Measure the current weather in real time and predict the future weather to be sent to at least one of the safety management control unit 100, accident probability calculation unit 500 and dangerous area information collection unit 400 to be useful for promoting worker safety. Can be.

In addition, the current weather information and the future weather forecast for the purpose of the work to send to the worker terminal 600 and the task manager terminal 700, if rain or wind is expected to work in advance to prepare for the worker You can prepare.

Therefore, the current and future weather information can be sent from the weather information collection unit 200 to the worker terminal 600 and the work manager terminal 700.

In addition, by sending the weather information including the current and future weather conditions to the accident probability calculation unit 500 calculates the probability of accident in real time so that workers and task managers can know the worker terminal 600 and the task manager The probability of accident can be sent to the terminal 700.

When the probability of an accident exceeds the predetermined accident probability threshold in the safety management control unit 100, the operation interruption command or the operation prohibition command may be sent to the worker terminal 600 and the operation manager terminal 700.

In this case, the output unit provided in the operator terminal 600 or the output unit provided in the work manager terminal 700 may be output.

The output method may be a method of sounding a warning siren or outputting a warning sound or a method of outputting a warning message on a screen.

The day job information collection unit 300 may collect information on the day job to be performed for the day in the day by day process management system for each line of the worker that is generally installed in the shipyard.

The same day work for each worker is assigned a unique serial number can be managed in the day job information collection unit 300.

When all the information on the day job is collected in the day job information collection unit 300 and delivered to the safety management control unit 100, the safety management control unit 100 sends this information to the accident probability calculation unit 500.

The accident probability calculation unit 500 may store information on which worker performs all the work in the shipyard and use this information to calculate the probability of each task.

There may be vulnerable work for each worker, and if a worker has suffered a slight sliding accident in the past, the worker may have a high probability of accidents in the work in the fall hazard area.

Analyzing accidents with a high probability of accidents by worker can be very effective in preventing accidents.

When calculating the probability of an accident, this can be considered if each task is adjacent or likely to affect it.

For example, if a crane is hoisting over a worker who is welding a ship, and the heavy material passes from above while the worker is working, the probability of accidents for the welding worker may be higher during that time.

Also, if the wind speed is suddenly increased while the crane is hoisting, the probability of an accident may be higher.

The dangerous area information collecting unit 400 may predict the dangerous area in real time.

Prediction of dangerous zones can be made by predicting dangerous zones when the probability of accident exceeds the preset probability when working in the dangerous zone.

For example, a dangerous zone due to heavy lifting may statistically calculate the probability of an accident due to heavy lifting of the worker who was actually working below when lifting the heavy lifting, and then calculate the statistics for the past 10 years If the probability is more than 1 percent, the area may be predicted as a risk zone due to heavy lifting.

In addition, although the same hoisting operation, the probability of accident is 0.5% when the wind speed is 1km / sec, so the lower section of the hoisting operation can be predicted as not a dangerous area, but when the wind speed exceeds 10km / sec, the statistical accident probability is 1.1. As a percentage, the lower section of the hoisting operation can be predicted as a hazardous area.

By strengthening the criteria for hazardous areas, no matter how light the lifting material is, the area below the predetermined area may be set as a dangerous area unconditionally when the lifting material is being worked on.

When the danger zone is predicted, the danger zone information may be sent to at least one of the accident probability calculation unit 500, the worker terminal 600, and the work manager terminal 700.

The safety management control unit 100 may warn the worker by sending a danger zone warning signal to the worker terminal 600 within the danger zone or within a certain distance from the danger zone.

In addition, by sending to the task manager terminal 700 carried by the task manager of the worker who is in the danger zone or within a certain distance from the danger zone, the task manager can also cope with the dangerous situation.

The safety management control unit 100 receives the weather information from the weather information collection unit 200 when the prediction of the danger zone in the dangerous area information collection unit 400, and receives the same day work information from the day work information collection unit 300 The dangerous zone information collection unit 400 may be sent to the dangerous zone information collection unit 400, and the dangerous zone information collection unit 400 may predict the dangerous zone using the weather information and the same day work information received from the safety management control unit 100.

In addition, the dangerous area information collecting unit 400 can analyze the accident case calculation unit 500 information about the company accident case, ostrich ship accident case and construction site accident case to more accurately predict the danger zone. .

For example, within a certain distance of a worker working with flammable materials, it may be set as a fire hazard zone, and a high wind speed may widen the danger zone.

In addition, where the accident frequently occurred in the past, the area of danger area can be made larger.

For example, the dangerous area information collecting unit 400 uses the standard of the accident rate calculation unit 500 of the case probability storage unit of the case probability storage unit 540 of FIG. Can be set to more than%.

However, the dangerous area information collecting unit 400, if the statistical accident probability of the area is more than 3 percent, frequent accidents, even if the probability of accidents in the surrounding area is less than 1 percent, 10 Areas within meters can be predicted as danger zones, resulting in a wider estimate of the area of danger zones.

This setting allows for more complete operator safety management.

When the dangerous zone information is sent to the accident probability calculation unit 500, the dangerous zone information may be used so that the accident probability is more accurately calculated.

The accident probability calculation unit 500 may calculate the accident probability by combining various information in the shipyard, including weather information, day work information, and danger zone information.

The accident probability calculation unit 500 may notify the worker in operation of the accident probability in real time.

In addition, such an accident probability can also be sent to the task manager terminal 700 to allow the task manager to manage a worker who ignores or inadvertently continues to work even if the probability of accident increases.

As reference information for calculating the probability of an accident, we can refer to an accident case in a shipyard in which a shipyard safety management system according to the present invention is installed.

In addition, the accident probability calculation unit 500 may be used to calculate the probability of accident by receiving information from other shipyard accident cases or announcements or newspapers of other shipyards.

For example, the probability of accident can be calculated by combining the recently developed big data technology with artificial intelligence technology.Refer to the weather information, the worker who worked on the quay at the wind speed of 20km / sec in Gyeongsangnam-do, If the accident occurred in another shipbuilder by the shipbuilder, such cases are automatically obtained through at least one keyword of shipyard, anti-slip, seawall, sea, and fall and added to existing statistics. The accident probability calculation unit 500 may calculate a higher probability of accident under the same condition.

In addition, it is possible to refer to the accident cases of the construction site of another construction company.

By accumulating these accident cases continuously, the predicted accuracy of accident probability can be increased.

2 illustrates a configuration of the weather information collecting unit 200 according to an embodiment of the present invention.

Referring to FIG. 2, the weather information collecting unit 200 of the present invention includes a weather information transmitting unit 210, a weather information storing unit 220, an outdoor temperature prediction unit 230 for each time zone, and an indoor temperature prediction unit for each time zone 240. ), A time zone wind and wind prediction unit 250, a time zone wave prediction unit 260, a time zone noise and vibration prediction unit 270 and a time zone rainfall prediction unit 280.

The meteorological information transmitting unit 210 stores the meteorological information stored in the meteorological information storage unit 220, the safety management control unit 100, the accident probability calculating unit 500, the worker terminal unit 600, and the task manager terminal unit 700. You can send to at least one of the.

The accident probability calculation unit 500 that receives the weather information may use the weather information when calculating the probability of accident.

When receiving the weather information from the worker terminal (600 of FIG. 1) or the work manager terminal (700 of FIG. 1), the weather information is sent to the worker terminal (600 of FIG. 1) or the work manager terminal (700 of FIG. 1). The confirmed worker or work manager can prepare the work according to the weather situation or prepare appropriately on site.

For example, if a lot of rain is expected, workers or work managers can prepare to avoid flooding where there is a risk of flooding.

The weather information storage unit 220 is an outdoor temperature prediction unit 230 by time zone, an indoor temperature prediction unit 240 by time zone, a wind speed and wind prediction unit 250 by time zone, a wave prediction unit 260 by time zone, and a time zone Information may be received and stored from at least one of the noise and vibration prediction unit 270 and the hourly rainfall prediction unit 280.

The outdoor temperature prediction unit 230 for each time zone may collect information on the external temperature.

Such information is obtained using outdoor weather forecasts and temperature sensors installed throughout the shipyard to obtain outdoor temperature information through wired or wireless communications.

The combination of such information may store the current outdoor temperature and the future outdoor temperature prediction time in the weather information storage unit 220.

Accumulation of such outdoor temperature information is very important because it is possible to improve the accuracy by continuously checking the error of the outdoor temperature prediction value.

The stored time zone outdoor temperature prediction value may be updated by re-prediction by the time zone outdoor temperature prediction unit 230 in real time.

Time zone indoor temperature prediction unit 240 may collect information about the temperature of the room.

The indoor space where the work is performed may include various spaces such as the inside of the ship's block, the cargo hold of the LNG carrier on the quay wall, and the inside of the engine room being inspected for delivery.

Receives information on the current indoor temperature from the temperature sensor of each space, and estimates the future indoor temperature by various information including the number of workers in the future work, whether the fire is handled, the amount of ventilation per hour and the temperature of the ventilated outdoor air. It can be calculated and stored in the weather information storage unit 220.

It is very important for the operator to know the temperature and forecast of the workspace at work.

If the temperature is too hot or cold, the worker's concentration decreases and the probability of accident increases.

The hourly wind speed and wind direction prediction unit 250 may collect information on the wind speed and the wind direction.

Various ships may be equipped with various sensors for detecting wind speed and direction.

There may be various large structures such as goliath cranes, offices, quay walls, material stockyards and large ships in the shipyard.

Therefore, the Korea Meteorological Administration can receive real-time information on the wind speed and direction of the area where the shipyard is located.

Due to the large structures scattered throughout the shipyards, the direction and speed of the wind change, so the wind direction and wind speed of the yard's workplace can be measured and predicted separately.

Among the various tasks performed in the shipyard, there are many tasks that become dangerous when the wind speed is excessive.

For example, when lifting and moving a relatively light and bulky object during hoisting, it is heavily influenced by wind.

In addition, during the welding operation, welding sparks may be blown to a considerable distance by the wind, which requires special attention because fires often occur in shipyards.

In addition, since the wind is also affected by the change in temperature, wind speed and wind direction can be predicted for each time period in consideration of these factors.

The prediction of the wind speed and the wind direction is sent to the weather information storage unit 220 and stored together with the current wind speed and wind direction.

These estimates should be updated in real time and monitored for increasing probability of accidents.

The hourly wave prediction unit 260 may detect the current wave.

In order to detect the current wave height and frequency, a buoy at a specific point may be used, and various sensing devices for detecting the wave may be used.

The height and frequency of the wave should be set as far away as possible from the shipyard's workshop, and the more accurate the forecast will be from detecting a wider range of ocean waves, but it can be costly, so work mainly on yard workshops, docks, and quay walls. Waves located within a distance of 500 m from this space can be measured.

Measuring and predicting waves can be very important.

For example, when the ship is docked on the quay, the shaking of the ship may be the biggest obstacle in the work of maintaining accuracy.

Therefore, if the ship knows that the ship will be greatly shaken in advance and the time is avoided, the work efficiency can be increased and the safety of the worker can be achieved.

Since the waves can come from the distant sea to the near sea, measuring the waves in the distant sea can predict the waves occurring in the near sea.

The hourly noise and vibration prediction unit 270 may detect and predict vibrations generated when an earthquake or other work passes or heavy equipment such as a transporter or a crawler crane.

In addition, there are various noises in shipyards, which can pose a significant threat to the safety of other operations.

There is a risk of hearing loss due to long-term noise, and it may be difficult to communicate with workers in a noisy place, resulting in an accident.

Sound meter can be installed at each shipyard to receive the data.

In addition, it is possible to obtain a movement plan of heavy equipment in advance to predict the noise and vibration expected to occur when moving by floor conditions for each heavy equipment.

However, it is very difficult to predict the occurrence of an earthquake. At this time, it is possible to use the forecast of the Meteorological Agency, or to calculate the time to reach the shipyard if an earthquake is detected by the surrounding seismograph.

If the earthquake is high, the probability of accidents for all jobs in the yard can rise dramatically, especially in heights, which can be more dangerous.

Rainfall prediction unit 280 for each time zone may measure or predict the amount of rain falling per hour in the shipyard, or may utilize weather forecast for the forecast.

Figure 3 illustrates the configuration of the day job information collecting unit according to an embodiment of the present invention.

Referring to FIG. 3, a day job information collection unit 300 according to an embodiment of the present invention may include a day job information transmitter 310 and a day job information storage unit 320.

The day job information transmission unit 310 calculates the accident probability calculation unit for a variety of information about the job, such as the job number of the planned job to be made on the day and the worker, the line and location of the job, the movement path and travel time for the work, rest time ( 500 of FIG. 1.

The accident probability calculation unit 500 of FIG. 1 receives work information that is made on the day, and calculates an accident probability by work number.

The day job information storage unit 310 may store a variety of information about the job, such as the job number and the worker, the line and location of the job, the movement path and movement time, the break time for the job to be made on the day.

The day job information storage unit 310 may include a method of receiving and storing information on a job having an input device, and a job management system in a shipyard exists separately to receive and store necessary information about a job from the job management system. It may be a way to.

In order to receive information about a job from a separate job management system, the day job information storage unit 320 may include a day job information receiver (not shown).

4 illustrates a configuration of the dangerous area information collecting unit 400 according to an embodiment of the present invention.

Referring to FIG. 4, the dangerous zone information collecting unit 400 according to an embodiment of the present invention includes a dangerous zone information transmitting and receiving unit 410, a dangerous zone information storing unit 420, and a strong wave urban dangerous zone predicting unit 430. Danger Zone Prediction (440), Fire Danger Zone Prediction (450), Fall Danger Zone Prediction (460), Strong Wind Danger Zone Prediction (470) and Low Oxygen Danger Zone Prediction (480) ) May include one or more of the following.

The dangerous zone information transmitting / receiving unit 410 may send the dangerous zone information to at least one of an accident probability calculating unit (500 of FIG. 1), an operator terminal (600 of FIG. 1), and a task manager terminal (700 of FIG. 1). .

Prediction section 430 for strong urban danger zone, Prediction zone 440 due to heavy wounds, Fire zone prediction zone 450, Fall zone prediction 460, Strong wind danger zone prediction section ( 470) and various dangerous zone information predictable by at least one of the hypoxic dangerous zone prediction unit 480 may be stored in the dangerous zone information storage unit 420, and continue to be stored in the dangerous zone information storage unit 420 if necessary. By using the accumulated danger zone information, the problem prediction can be identified and corrected by examining whether the prediction of the danger zone is accurate.

In addition, various information is required to predict the danger zone. The weather information collected and predicted through the weather information collecting unit (200 of FIG. 1) is transmitted to the danger zone information storage unit 420 through the danger zone information transmission / reception unit 410. Stored.

The stored weather information includes a strong wave hazard prediction section 430, a danger zone prediction section 440 due to heavy goods rights, a fire occurrence zone prediction section 450, a fall danger section prediction section 460, and a strong wind speed hazard. The area predictor 470 and the hypoxic danger zone predictor 480 may be used as information for predicting a danger zone.

In addition, work information collected by the day's work information collecting unit (300 of FIG. 1) may be necessary to predict the danger zone.

For example, if the welding sparks are splashed by welding, the surrounding area may be a fire hazard area.

In addition, if heavy lifting operations are being carried out, the lower part may be set as a dangerous area due to heavy lifting.

The strong wave danger zone prediction unit 430 may predict a zone that can fall or be impossible when a person stands when the wave strikes, and when the wave is severe, the work inside the ship that is fixed to the quay is moored. It can be dangerous, so the space inside these ships can be predicted as a danger zone.

In addition, the information about the height and the frequency of the waves from the weather information collection unit 200 may increase the accuracy in the prediction of the strong city danger zone in the strong city danger zone prediction unit 430.

The dangerous area prediction part 440 due to the heavy goods winding can predict in real time the area that becomes dangerous when various cranes installed in the shipyard carry various heavy goods such as ship blocks necessary for the construction of the ship.

In addition, the hourly predictions of the wind speed and the wind direction predicted by the hourly wind speed and the wind direction prediction unit (250 of FIG. 2) may improve the accuracy of the prediction of the dangerous area predicted by the dangerous area prediction unit 440 due to the heavy lifting. have.

The fire hazard zone prediction unit 450 predicts a danger zone where a fire may occur in a shipyard, in particular, in a shipyard, since there are many cases where a fire occurs in a ship working on a quay wall, a large loss occurs.

Regarding the occurrence of a fire, there is a risk of fire if the work is to handle flammable materials or to handle fires such as torch, such as welding.

In addition, when working with electricity on a rainy day, a fire may occur due to a short circuit.

Fall risk zone prediction unit 460 may be a fall risk when working in height, the case of working near the cliff structure or the work on the chief can be said to fall risk.

Dangerous zone prediction unit 470 at the strong wind speed may fly dangerous objects during operation at a strong wind speed, it may be more easily spread in the case of fire.

In addition, when the wind speed is strong, it may be dangerous even at the time of heavy lifting, in which case it may be set to overlap the dangerous zone due to heavy lifting and the dangerous zone at the strong wind speed.

The hypoxic danger zone prediction unit 480 may predict an area where the oxygen concentration falls below the oxygen concentration reference value.

For example, when the worker enters the confined area while working in the airtight area and concentrates on work, a large disaster may occur after the worker's breathing does not consider the oxygen concentration to be dangerous.

In this case, when the oxygen concentration in the closed area is predicted and the oxygen concentration falls below the oxygen concentration standard value according to the worker's work, the operator sets the hypoxic danger zone and outputs it to the worker terminal (600 in FIG. 1). Make sure you have time to leave the confined area.

Can be sent to at least one of 700).

In addition, the probability probability information transmission and reception unit 510 receives the information necessary for calculating the probability of accident in the probability calculation unit 530, that is, the probability information storage unit by receiving a variety of information including the day work information and weather information and dangerous zone information 520 can be stored.

The probability calculation unit 530 may calculate the probability of accident using various pieces of information stored in the accident probability information storage unit 520.

The information used to calculate the probability of accidents can be used in the case of construction accidents in case of the accident of our company and the case of other shipbuilding accidents, in addition to the day work information, weather information and danger zone information.

An example of storing the case of another shipyard as a keyword through newspapers and applying it to calculate the probability of accident was described above.

In addition, since the working environment of the shipyard in which the shipyard safety management system according to the present invention is installed is different from the shipyard in which the accident occurred, the information related to the accident may also be inaccurate. .

The construction site accident case may be collected and stored in the construction site case storage unit 560.

The construction site accident case storage unit 560 collects and stores information published by an injured construction company and media reports in connection with an external communication network such as the Internet, and reviews the stored accident cases to calculate the probability of our accident. If the case is applicable, it can be sent to the accident probability storage unit 520 and stored.

Cases of accidents at the construction site cannot be investigated in detail except the announcements and press reports of the construction company, and the construction site and the shipyard may be different due to the difference in work.

Therefore, the construction site accidents can be referred to with less weight when calculating the probability of accidents than those of other shipbuilding accidents.

For example, if an accident at a construction site was collected through keywords such as oxygen welding, cutting work, and fire when searching the Internet, even if the humidity in the air was about 80 percent, the cutting work was performed by oxygen welding. If so, the calculation of the probability of accident may change by changing existing statistics.

However, as described above, only 50 percent of Ostrich accidents and 20 percent of construction site accidents are considered.
