Description

Method and Apparatus for Safety Management through Creation of Working Daily Report using Individual Location Information of Workers in Construction Site}

The present invention is to prevent safety accidents that occur during construction at construction and industrial construction sites, and more specifically, by generating real-time work daily information from the location information of the workers of a number of partners in the temporary civil engineering construction electrical equipment environment plant, Is about preventing disasters by analyzing unsafe work.

At the construction site, each supplier prepares a work daily report for today's work to indicate the plan, or a major construction type supplier prepares a weekly schedule to establish a construction plan for a wider period.

However, only a few of the dozens or hundreds of suppliers of civil engineering, construction, electricity, equipment, environment, and plants participating in the construction are preparing work schedules or schedules.

Work daily reports and schedules are also written in A4 format Excel or word processor and printed on paper. This is because it is difficult for all suppliers to have facilities such as offices, PCs, and printers to prepare work plans, and it takes a lot of time and effort to prepare and submit documents.

Accordingly, it is difficult to comprehensively grasp the entire work contents of many workers.

In particular, since work is performed according to the type of construction divided into electrical facilities, etc., the risk of safety disasters due to mutual interference or conflict inconsistency exists, and effective management for this is insufficient.

Therefore, if it is possible to efficiently grasp the contents of all work performed in the field and systematically analyze problems such as inconsistency or collision between works, it will be possible to reduce safety accidents by taking countermeasures.

In order to solve the above problems, in the present invention, in the present invention, a safety standard regarding what state of the work should be performed and in what order the work should be performed, and after grasping the work contents of workers in the field in real time, safety We try to prevent disasters by analyzing work that exceeds the standard.

In order to solve the above technical problem, the present invention

Evaluate the risk of equipment, materials, construction methods, and construction order necessary for suppliers to work.

Define what other dangerous tasks are in the same workspace.

By analyzing the effects of the preceding work and the effects of the subsequent work, comprehensively analyzes in time series whether the current work is safe when the preceding work is in a certain state.

In order to determine whether a specific task is dangerous, a risk assessment standard is established through objective data standards, laws, regulations, cases, expert opinions, etc.

Standards for safety facilities (height, strength, size, installation time, retention period, dismantling time), and work conditions (temperature, humidity, wind, toxic gas, lighting, electric shock, pressure, etc.) , The condition of the difference between the schedule of the preceding work (the condition that the preceding work must be completed), and the condition of the difference between the schedule of the subsequent work (the condition that the following work must follow) are included. These data are classified by work by work type and converted into DB.

The method of collecting work information is to determine what kind of work a specific worker is from from the company to which the worker belongs, the scope of the work contract, the work scope, the work classification system, and the name of the work.

And it analyzes what kind of work is currently being performed in a specific place by grasping what kind of work the worker is currently working in from the location information.

Alternatively, information about where and what workers are currently working on is collected from the smartphone from the work team leader or class manager by morning, afternoon or hour.

When the work details for each worker or company are identified as described above, the control unit generates a real-time work daily report or a schedule for the current construction work by synthesizing the work contents for each dong, floor, zone, and room location.

In addition, the control unit analyzes the work exceeding the safety standard by comparing the work daily report, the process table, and the safety standard database.

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

Temporary civil engineering, construction, electrical equipment, and environmental plant construction is subdivided by level of activity task of large construction type, heavy construction type, small construction type, and safety standards for each operation are prepared. In accordance with this standard, objective and systematic safety standards are established for which conditions or order of work is dangerous.

The company, type of work, type of work, workable space, and work details related to workers are made into a database to form worker's job type information.

From the worker's access and location information (iris recognition, hand blood vessel, RFID, beacon, etc.), it identifies the location, location, and space of the worker.

From the job type information and location information, after grasping what work is currently being performed in a certain place, a work daily report or a schedule is comprehensively composed.

It analyzes in real time what work in a certain place is dangerous by exceeding the safety standard through the comparison of the work content of the work daily report or the schedule with the safety standard.

According to the present invention, it is possible to analyze dangerous jobs in real time for all jobs in the field as described above.

In the past, work plans were generally prepared from work schedules or schedules on a daily basis, but changes or cancellations of plans, changes in work order, initiation of work not in the plan, spaces not in the plan, work at places, and work not in the plan The safety risk increased according to workers' dispatch and input of work.

According to the present invention, it is possible to analyze safety risks based on the existing work plan (Muniday work day, weekly schedule) and by configuring all currently ongoing work in the field in real time, so that safety accidents do not occur.

Hereinafter, a safety analysis device and method through real-time generation of a working daily report using worker location information according to the present invention will be described in detail.

FIG. 1 is a block diagram showing the configuration of a safety analysis server 20 and a terminal 10 for analyzing safety risks by generating a working daily report using worker location information according to an embodiment of the present invention.

Referring to FIG. 1, the safety analysis server 20 through generation of a work daily report using worker location information according to the present embodiment receives and determines worker location information, and provides a function to the terminal 10. The terminal 10 is responsible for the function of inputting and querying worker location information.

2 is a diagram showing the device configuration of the safety analysis server 20 that analyzes safety risks by generating a work daily report using worker location information according to an embodiment of the present invention.

Referring to FIG. 2, the functional configuration of the safety analysis server 20 according to the present embodiment is a control unit 21, a safety standard database 22, a worker information database 23 and a work daily report database 24, and a safety analysis database. (25) and drawing (26).

The control unit 21 stores the safety standards of the work of the safety analysis server 20 in the safety standard database 22, and stores worker information in the worker information database 23.

In addition, the work details are read from the work daily report database 23, the drawings in the drawing 26 are read, a work daily report or a schedule is created (24), and then compared with the safety standards and stored in the safety analysis database 25. And it is responsible for the function of transmitting the result of the safety analysis (25) to the terminal (10).

The safety standards database 22 stores safety standards for specific tasks. For example, the name of the job is to clean the septic tank, and the safety standards and rules are to measure the concentration of oxygen and harmful gases, perform ventilation, and wear an air respirator or oxygen mask.

When the concentration of hydrogen sulfide reaches 20~30ppm, the olfactory nerve cells become fatigued, and if the concentration exceeds 700ppm, the oxidative capacity in the blood is exceeded, and the neurotoxic effect occurs by attacking the nerve cells.

The safety standard database 22 also stores conditions of a preceding operation or a condition of a subsequent operation for a specific operation. For example, in the work of a specific equipment type, it is important whether the valve is closed in the preceding work.

If the valve is not temporarily opened and closed, it is the case that an explosion or piping bursts during work in a subsequent construction type.

As a condition for subsequent work, if a specific work is spraying insulation on a material with high fire risk, a refractory material covering the painting material should be followed. If subsequent work is not undertaken or follows late, the insulation coating is greatly exposed, increasing the risk of fire.

Set the schedule difference or process rate difference between the current work of spraying insulation and the subsequent work of applying refractory materials. Since this difference may vary depending on the number of floors and area, it is desirable to set it in consideration of site characteristics.

The worker information database 23 stores information about a worker's job, including a company, a type of work, a job type, and a workable area (space). For example, worker A is a waterproof work worker in the basement section.

The work daily report database 24 analyzes which work is being performed at what time and at what place from the location information of the worker and the worker information, and then shows what work is comprehensively performed at what spatial location from the information of multiple workers. Save the analyzed work day or schedule information.

The safety analysis database 25 is a result of the control unit 21 analyzing the safety risk of each job through a comparative analysis between each job in the work day report 24 or group work at a specific space location and the safety standard 22 Save it.

For example, if piping work including thinning and pipe cutting (welding flame) and ceiling insulation work using highly flammable polyurethane materials are carried out in the machine room on the first basement floor, a quantitative analysis of the content that the possibility of fire is high. This is the result of risk analysis.

The drawing 26 stores a drawing indicating the construction status of the current construction underway, a zoning diagram, and a workable space within the contract scope of each partner company. The drawings are used to indicate the location of workers, analyze safety risks, and display analysis results.

For example, it is used to indicate whether the wall of the machine room on the first basement floor has been constructed, what workers are working in the machine room, and what kind of work risks are present.

3 shows an additional functional configuration of the safety standard database 22 according to an embodiment of the present invention.

3, the work classification system 221, the work list 222, the safety standard 223, the accident case 224, and the safety measures 225 information of the safety standard database 22 according to the present embodiment. Save it.

The work classification system (221) is a work breakdown structure (WBS) that has temporary construction, earthworks, construction work, electrical work, facility construction, and others as major construction types and classified as medium construction types and small construction types. This work breakdown system has codes and names, and has been written and used in the industry.

However, depending on the construction, some items may be missing or added. Hotel construction and office construction, apartment construction, factories, etc. may have different types of work classification system. The work breakdown structure 221 is similar to the cost breakdown structure (CBS), but is a system for classifying construction work.

The work list 222 is a list in which work is divided by line by floor and room based on the work classification system 221. RC construction is carried out in units of floors, so from the classification system of reinforced concrete construction 303, it is divided into zones for each floor, such as 5 basement levels, 4 basement levels to 50 floors above ground.

Also, the task list is composed of detailed tasks at the bottom. The 10th floor RC construction is composed of column reinforced column frame slab form, slab reinforced concrete electrical equipment work.

The safety standard 223 stores safety standards for specific tasks. It stores the contents of the safety standards of the work itself and the standards for predecessor work, follow-up work, and spatial work in the top, bottom, left and right.

The accident case 224 is a database that systematically organizes cases of accidents that occurred during construction in the past. Accident cases include the work classification system, causes, and countermeasures. Accident cases are used as analysis data of the degree of risk, consequences, and countermeasures compared to accident cases when similar construction is planned or in progress at the site.

The safety measures 225 stores information on how to take measures when the risk of a specific work is evaluated, related regulations, quantitative figures, and other site cases. Safety measures are prepared by safety managers and construction experts in each field. The above countermeasure information is used by construction officials to quickly and accurately establish professional solutions.

4 is a flowchart of a method for generating a real-time work daily report using worker location information according to the present invention.

Referring to FIG. 4 according to an embodiment, a safety expert, a contractor, and a partner prepare safety standards for each work (S10).

When the safety standard is created, it is systematically stored in the safety standard database 22 (S20). Here, as the system, a work breakdown system suitable for the construction characteristics of the site may be prepared, or a conventional civil construction electrical equipment construction type code may be used.

It includes a method of unifying the name of the work, creating a list in advance, and then selecting and inputting the work in progress in order to more quickly and accurately create the work in progress.

It also stores worker information including the worker's company, job type, work type, position, and equipment used (S30).

In addition, a worker location sensor is installed in the field so that the location information of the worker can be identified (S40). Location information sensors include beacons and RFID.

Now, when construction begins, the location information of each worker is identified (50). For example, if it is determined that worker A (waterproofing work) is in the machine room on the first basement floor, it is determined that worker A is performing waterproofing work. If the grasp of the work content is unclear or it is judged that it is necessary to check, you can contact the worker's team leader or inquire directly to the worker.

The control unit 21 comprehensively configures the work content (work daily report, schedule) for each building, floor, zone, area, room, and part (S60). For example, if it is analyzed that worker A (waterproofer) and worker B (facility plumber) are in the machine room on the first basement floor, it is analyzed that the current waterproofing work and plumbing work are currently in progress in the machine room on the first basement floor.

Another way is that the team leader of the work team can select the team members and designate the work location and time. For example, 5 people worked for waterproofing work, and 2 people in 1 team were put into the machine room on the 1st basement floor, and 3 people in the 2nd basement water tank waterproofing work. You can write worker information using a smartphone.

Next, the control unit 21 analyzes the task exceeding the safety standard by comparing the work daily report content (S60) and the safety standard (S20) (S70).

For example, if B is not input in a series of tasks that must be carried out in sequence with ABC, but workers are preparing to work in order to do C work in the corresponding place, it is judged that this is a violation of safety standards and may lead to safety disaster. .

And the control unit 21 outputs the safety analysis result (S70) to the terminal 10 (S80).

For example, the control unit reconfirms the situation at the site or issues an order to suspend construction, and sends a warning message to the construction company manager, the manager of the partner company, the team leader, the safety manager, and the safety monitoring team. Accordingly, the person in charge proceeds to the process of establishing countermeasures after checking the site situation.

As described above, according to the present invention, it is possible to analyze in real time the contents and risks of work being carried out in the field based on the original work plan. Accordingly, it is possible to grasp the location and contents of dangerous work in real time, and prevent or take immediate action, so that a safety disaster does not occur.

According to the present invention, the entire process is composed by comprehensively analyzing all the work in all locations and spaces in construction and industrial sites from the location information of the worker, and exceeding the safety standard through comparison with the safety standard database systematically established in advance. You can manage what you do.
