Description

Fire risk assessment method and device using Internet of Things beacons at construction sites

The present invention is to determine whether sufficient fire extinguishing equipment and fire watchers are arranged when performing tasks such as welding, cutting, and chemical substances that have a risk of fire during construction work, and in more detail, equipment capable of generating fire It is to quantitatively calculate the fire risk by attaching beacon sensors to materials, chemicals, and equipment and personnel that extinguish fires, marking them on construction drawings, and analyzing their mutual influence.

A number of safety accidents occur during construction work, and the damage caused by a double fire leads to serious disasters.

The cause of these fires occurs during operations that create fires around burning materials or chemicals. For example, flames are scattered due to pipe cutting work for facility piping in a specific underground area, and then the chemicals in the vicinity are ignited and then spread to urea foam, which is an insulation material for the ceiling, where toxic gas is generated and then spread to the entire basement. Damage occurs.

In order to prevent such fires, fire extinguishers or fire extinguishing equipment are placed near fire-hazardous work.

In addition, fire watchers are placed in fire-hazardous work sites, and fire watchers manage fire extinguishers, etc. to prevent fires from occurring.

The safety managers of construction companies are arranged for each floor or tool (zone) to perform safety accident and fire prevention activities while going around the site.

In addition, daily risk assessments, hazardous risk prevention plans, and safety management to prevent safety accidents are carried out by construction companies and partners.

After the construction is completed, various fire extinguishing and evacuation facilities (detectors, alarms, broadcasting, sprinkler, smoke duct facilities, etc.) are provided in the event of a fire, but fire extinguishing facilities are not yet installed during construction and only simple equipment such as fire extinguishers can be used. City workers and construction sites suffer great damage.

The causes of fire and problems according to the characteristics of the construction site are as follows.

Since workers work while moving the work place during construction, it is difficult to manage fire extinguishers because they must move together with the fire extinguisher.

There are cases in which the fire extinguisher of the worker group monitoring the fire risk is not aware of, ignores, or misunderstands the absence of a fire extinguisher in spite of a fire hazard operation.

The safety manager in charge of the safety of the construction company goes around the construction site and checks the safety, so it is not always located at the fire work location.

When working at night and late at night to meet the construction period, it becomes more dangerous at night because it is difficult to work like the daytime of safety managers.

During periods when the number of fire-hazardous work, such as interior construction, is large, the number of personnel managing safety is small, and fire monitoring may not be possible on a one-to-one basis.

During the finishing and interior construction periods, fire risk work is carried out at several locations on each floor at the same time, making it difficult to manage fire prevention.

Materials with high fire risk, such as chemicals, must be moved and stored in a separate management place after completion of work, so a lot of time and manpower are spent to check them.

Deploying a large number of safety managers increases labor and construction costs, and there is a difficulty in hiring safety managers.

Fire extinguisher performance checks or manufacturing periods are long, so it may not work properly.

The conventional manpower-centered fire monitoring method has a work place and time in which no manpower is assigned, and there is a problem such as neglect or misunderstanding even when the manpower is disposed.

Therefore, as one of the methods to solve the above problems and characteristics, there is a need for a plan to increase the efficiency of fire management by utilizing the Internet of Things recently introduced as a new technology.

Therefore, in the present invention, as a level at which experts can evaluate the fire risk at a specific work place all day, using the Internet of Things, the type and quantity of fire-generating equipment or chemical substances, the type and quantity of fire extinguishing equipment to extinguish a fire, and a fire watchdog, Together with the safety manager, we intend to analyze the number and distribution of workers in the vicinity who evaluate the degree of fire damage in real time for the entire area of the site. As a result, the situation room at the site can quantitatively know which workplace is the most dangerous and what is lacking, so that the risk of fire can be reduced through countermeasures and measures.

Fire-producing materials include oxygen cylinders, oxygen cutters, rotary saw cutters, electric welding machines, petroleum hot air fans, lignite stoves, flammable materials such as thinners and paints, explosive materials, combustible materials, insulation materials such as styrofoam, urea foam insulation, nonwoven fabrics, waterproof work materials, There are combustible materials, wood/plywood, electric heaters, electric short circuits, electric appliances, gas leaks, etc.

The method to achieve the purpose is to install beacons on equipment and chemical substances to determine location information, to specify whether it is a fire-causing or to extinguish a fire by specifying the properties of equipment and substances, and to prevent the fire suppression. The risk of fire is assessed by grasping the lights and analyzing whether the equipment is in operation.

Looking at whether it is possible to achieve this purpose through the contents of the existing patents, it is as follows.

Application No. 10-2013-0066108, application date June 10, 2013, In the safety management system and method for building construction using a portable terminal, use wireless communication in the field to identify the user of the terminal and the location of the terminal After transmitting the information and job information, it proceeds to check whether the confirmation button is pressed.

The safety instructions and action result report are composed of contents that deliver instructions from managers and requests from workers. Therefore, it is not possible to calculate even the fire risk because it is not known where and how much of the cutting machine, welding machine, and chemicals are.

In the application number 10-2016-0051916, application date April 28, 2016, the risk assessment device and method for chemical substances and the cited invention set the risk level according to the leakage of chemical substances, and the risk of accidents according to the temperature of the chemical process. It proceeds to evaluate.

Only by identifying the location of the above chemicals and the risk level and temperature, the cause of fires such as equipment and chemicals that occur in the workplace at the construction site cannot be identified, and the fire extinguishing ability cannot be evaluated.

Application No. 10-2014-0165609, filing date November 25, 2014 In the smart safety management service system, a beacon is installed in a dangerous place and when the user terminal approaches, the administrator transmits a message warning of danger.

With only the location measurement method that is dangerous when the user approaches a specific location, the cause of fire such as equipment and chemical substances that occur in the workplace of the construction site cannot be identified, and the fire extinguishing ability cannot be evaluated.

Application No. 10-2007-0010511, filing date February 1, 2007, In the system and method for providing a service using location information, a GPS receiving module capable of grasping the location information and an RF transmitting and receiving means using a Zigbee wireless network-based frequency It is provided so that the progress in a certain area such as a golf course can be grasped in real time.

A plurality of portable terminal modules including a GPS receiving module to generate a location signal indicating a location of itself and to display message information; And a management system module that receives the location signal using ZigBee wireless communication, displays the location of each portable terminal module, and generates message information according to a distance between the portable terminal modules.

In addition to displaying the location of each of the portable terminal modules according to the position signal of each of the portable terminal modules, a distance between the portable terminal modules is calculated by comparing and calculating the distance between each of the portable terminal modules to any one of a preset distance from 500m to 1000m If it is adjacent within, it generates and transmits the message information to be transmitted to the corresponding portable terminal module.

By identifying the location of the terminal and transmitting a message when the distance between the terminals is close, the cause of fire such as equipment and chemicals that occur in the workplace of the construction site cannot be identified and the fire extinguishing capacity cannot be evaluated.

The direction to solve this problem is to use equipment and systems together from manpower-oriented monitoring in order to manage fire risk work of the entire construction site by a small number of personnel.

Fire-hazardous equipment or chemicals and fire extinguishers must be accurately identified in real time to ensure they are always attached.

There is a need for a method to efficiently monitor fires not only during the daytime work from 7 to 5 in the morning, but also during the particularly vulnerable night and late night work hours.

It is also important to increase the prevention capability in advance so that a fire does not occur during construction from the point that the conventional technology is focused on finding and evacuating fire extinguishers after a fire.

The present invention was invented to solve the problems related to the prior art as described above, and after grasping the location and quantity of objects (materials), people, and walls at a specific location on a construction site through IoT Analyzes the risk of fire and the ability to contain the fire from the ability of the company to analyze the dangerous work place. Accordingly, fire management through quantitative analysis from fire management by manpower prevents fire from occurring.

In order to achieve the above object and solve the problems of the prior art described above, a fire risk evaluation method and apparatus using a construction site beacon according to the present invention

A beacon is attached to work tools (equipment), chemicals, combustion materials, fire extinguishing equipment, and people in a specific work place, and after identifying the location and quantity through a scanner, it is displayed on the architectural drawing, and the ability to generate fire in the above situation And fire suppression capabilities are calculated by reflecting the site conditions, and the degree of fire risk is analyzed in real time for 24 hours.

In order to quantitatively subdivide and understand the type, quantity, and influence of the fire cause, after setting the fire cause classification system and grade, diversify the types of corresponding beacons, and additionally equip some sensors to understand the capabilities of the fire cause in detail. Make it possible.

According to the present invention, the following effects can be expected.

If beacons are installed on work tools such as welding machines, chemical substances such as thinners, and combustible materials such as insulation materials that cause fire in a specific place such as the electric room on the 5th basement level at the construction site, the location and quantity of the cause of the fire will be affected. You can comprehensively analyze the fire generating ability.

Depending on the type of fire cause, different types of beacons can be attached. For example, in the case of an electric welding machine or oxygen cutting machine with the highest fire risk, the color of the beacon is dark red and the highest level 5 danger is indicated, attached to the welding machine, and additionally equipped with a temperature sensor and a vibration sensor. To be able to grasp. And let the beacon send out these signals. You can also attach a red grade 5 beacon to the thinner barrel.

Accordingly, the fire risk can be quantitatively calculated from the type and quantity of tools and materials that cause the fire, and whether they are in use. For example, if a welding machine is in use, thinner or paint is in close proximity, and burning materials are accumulated, the risk of fire is considered very high.

As a fire extinguisher, fire hydrant, fire extinguisher, fire hydrant, fire watcher, and safety manager installed beacons to extinguish fires in the event of a fire, the location and quantity can also be comprehensively identified. A blue beacon is installed on the fire extinguisher to indicate the grade according to the fire extinguishing performance, and additionally include the date of manufacture, inspection information, etc., send such a signal, and scan the signal.

As a result, the ability to extinguish a fire can be quantitatively calculated from the type and quantity of tools and substances to extinguish the fire, whether they are in use, and the number of people. For example, if one welding machine is in use, one fire watcher and two safety managers are nearby, and there are two fire extinguishers, the fire extinguishing capability can be calculated.

During construction, frames and walls are created over time, and if they are marked on CAD drawings, a practical fire suppression method that reflects the actual structural condition of the site can be derived.

By introducing the concept of working hours as a criterion for evaluating the risk of fire, it is possible to determine whether the power of the welding machine, which is a fire generating tool, is turned on at night or when there is no work at night. In addition, after the work is completed, if the chemical substances that must be moved to the first floor dangerous goods storage remain in the work place on the 12th floor, and there are no workers around and leave work, it can be judged that the dangerous substances are left alone on the 12th floor.

It is possible to prevent problems such as the conventional manpower-centered fire management, conditions in which people cannot continuously monitor the work place, neglect of dangerous tools and materials, non-displacement of fire extinguishers, or insufficient quantity of fire extinguishers due to misunderstandings and errors.

The scale of damage in case of fire can be calculated from the location of the workplace with high fire risk and the number of workers in the vicinity. It is possible to calculate the probability of a fire in the warehouse on the 6th basement level, and to determine the size of the damage by scanning the number of workers in each basement level.

If the fire risk is high, the fire risk can be reduced by increasing the distance between the hazardous materials or by sequentially performing dangerous tasks by quantitatively calculating and comparing the fire generating ability according to the fire hazard tools and materials and the fire fighting ability according to the fire extinguisher and the person. have. In addition, measures can be taken to increase fire suppression capabilities.

By summing the fire-producing capability and suppression capability of a specific site from each site, you can calculate the value of the entire site, so you can determine which site is the most dangerous and if you need help. At the site level, the site level, the construction company level, the municipality, the county, and the administrative unit level can be evaluated, enabling intensive support for vulnerable areas.

As above, fire risk can be quantitatively identified in real time, 24 hours a day, for large-scale construction sites, dozens of construction sites, or construction sites in specific cities and counties, so that the fire does not occur by taking necessary measures.
