In describing the present invention, if it is determined that a detailed description of a known technology related to the present invention may unnecessarily obscure the gist of the present invention, the detailed description will be omitted. Hereinafter, preferred embodiments according to the present invention will be described in detail with reference to the accompanying drawings. In the drawings, the same reference numerals are used to indicate the same or similar components.

1 is a network configuration diagram for explaining a construction site safety management system according to an embodiment of the present invention.

Referring to FIG. 1 , the construction site safety management system includes a construction site safety management server 100 , a worker terminal 200 , and a manager terminal 300 . The construction site safety management server 100 includes an education completion information database 110 , a certification database 111 , a career information database 112 , a worker database 113 , and a health checkup database 114 .

The construction site safety management server 100 receives and stores worker profile information from the worker terminal 200 through communication with the worker terminal 200 . In this case, the worker profile information may include personal information, career history, education history, health examination history, and the like.

First, the construction site safety management server 100 provides the training completion information registration procedure to the worker terminal 200 before the worker goes to work, and receives the training completion information through the training completion information registration procedure.

In this case, the education completion information may include a name, a date of birth, a registration number, a completion date, a photograph of the completion certificate for each education completion certificate, and the like. The above education certificate is a certificate issued after completing the education on construction site safety management, and may include a basic health certificate and the like.

When issued by an education completion issuing organization, the education completion certificate may be issued by inserting a verification code for determining whether authenticity is authentic. That is, when printed by the education completion issuing organization, pixel spaces of different sizes corresponding to the authenticity identification code are output and issued together.

As described above, when the education completion certificate is issued by the education completion issuing organization, the authenticity determination code inserted into the education completion certificate is received from the education completion issuing organization server and stored in advance. Accordingly, the construction site safety management server 100 may determine the authenticity of the education completion certificate by using the authenticity determination code received from the education completion issuing organization server.

Because the pixel space of different sizes inserted in the above education certificate is set to a color similar to the background screen of the education certificate (that is, a color corresponding to a value whose RGB value is above or below a certain value), the user's Although it is invisible to the naked eye, when the pixel is analyzed in the process of the construction site safety management server 100 scanning to determine the authenticity of the training certificate, the pixel space corresponding to the authenticity determination code can be extracted because the pixel values are different. .

Therefore, the construction site safety management server 100 extracts a plurality of pixel spaces from the education certificate in the process of scanning and analyzing the education certificate, and then generates the authenticity determination code using the binary value indicated by the dotted dots in the plurality of pixel spaces. can do.

For example, when the construction site safety management server 100 extracts 1 pixel space composed of 4 dots and 6 pixel spaces composed of 8 dots, it recognizes the pixel space composed of 4 dots as 1, and 8 By recognizing the pixel space made up of dots as 0, it is possible to generate the authenticity determination code "1000000".

As another example, when the construction site safety management server 100 extracts 2 pixel spaces composed of 6 dots and 3 pixel spaces composed of 8 dots, the pixel space composed of 6 dots is recognized as 1, and 8 A pixel space made up of dots is recognized as 0, and the authenticity determination code "11000" is generated.

Then, the construction site safety management server 100 may determine the authenticity of the education certificate by comparing the authenticity determination code and the previously received authenticity determination code.

As described above, the construction site safety management server 100 determines the authenticity of the training completion certificate and calculates the effective time and training time for each training using the training completion information recorded on the training completion certificate, and then lists the training types for each worker. And the authentication time is stored in the education completion information database (110).

In this case, if the accumulated training time corresponding to the worker exists in the training completion information database 110, the accumulated training time is updated by reflecting the training time in the accumulated training time.

Then, the construction site safety management server 100 generates a worker training list, and provides the worker training list to the worker terminal 200 .

In this case, the worker training list may include a manager, company, site, date, name, date of birth, whether newcomer training has been completed, effective period, whether to go to work, a list of required training, whether or not required training has been completed.

Then, the construction site safety management server 100 receives the attendance authentication information from the worker terminal 200, and after the training of the worker is carried out according to the worker training list from the manager terminal 300, the training proof photo and training proof information Receive a training completion confirmation request message including

At this time, the attendance certification information may include the name of the worker and the name of the supervisor, and the training proof information includes the training category, training target, work type name, training date, training location, training time, training manager (manager, etc.), training content and the like.

The construction site safety management server 100 authenticates attendance by using the attendance authentication information in the training completion confirmation request message, extracts the training proof information, and then uses the training proof information to train each worker stored in the training completion information database 110 Update the type list and accumulated time.

That is, the construction site safety management server 100 calculates the effective time and training time for each training by using the training proof information, updates the training type list for each worker using the training type, and calculates the accumulated time using the certification time. It is updated and stored in the training completion information database 110 for each worker.

In addition, the construction site safety management server 100 provides a certification acquisition information registration procedure to the worker terminal 200, receives certification acquisition information through the certification acquisition information registration procedure, and stores certification acquisition information for each worker in the certification database 111 save to

At this time, the certificate acquisition information includes required information and optional information for each certificate, and the required information includes title, name, nationality, resident registration number, address, nationality, issuance date, aptitude test, expiration date, holding license, and proof photo, The selection information may include an insurance policy, a business registration certificate, an equipment registration certificate (eg, a result of a non-destructive inspection of a crane, a pump car, etc.), a photographic evidence, and the like. The above certificate is a certificate issued after the technology available at the construction site is certified through testing, and may include a machine pilot.

When the above certificate is issued by an organization in charge of testing a technology available at a construction site, a verification code for authenticity may be inserted and issued. That is, when a certificate is issued by an institution, pixel spaces of different sizes corresponding to the authenticity identification code are output and issued together.

As described above, when the certificate is issued, the authenticity determination code inserted into the certificate is received from the certification test hosting organization server and stored in advance. Accordingly, the construction site safety management server 100 may determine the authenticity of the certification by using the authenticity determination code received from the certification test hosting organization server.

Because the pixel space of different sizes inserted in the above certificate is set to a color similar to the background screen of the certificate (that is, the color corresponding to the RGB value of the background screen being above or below a certain value), it is not visible to the user. Although it is invisible, when the construction site safety management server 100 analyzes the pixels to determine the authenticity of the photographic evidence such as certification, the pixel space corresponding to the authenticity determination code can be extracted because the pixel values are different.

Therefore, the construction site safety management server 100 extracts a plurality of pixel spaces from the photographic evidence such as qualifications in the process of scanning and analyzing the photographic evidence, such as certification, and then uses the binary value indicated by the dotted dots in the plurality of pixel spaces. Thus, the authenticity determination code can be generated.

For example, when the construction site safety management server 100 extracts 1 pixel space composed of 4 dots and 6 pixel spaces composed of 8 dots, it recognizes the pixel space composed of 4 dots as 1, and 8 By recognizing the pixel space made up of dots as 0, it is possible to generate the authenticity determination code "1000000".

As another example, when the construction site safety management server 100 extracts 2 pixel spaces composed of 6 dots and 3 pixel spaces composed of 8 dots, the pixel space composed of 6 dots is recognized as 1, and 8 A pixel space made up of dots is recognized as 0, and the authenticity determination code "11000" is generated.

Then, the construction site safety management server 100 may determine the authenticity of the certificate by comparing the authenticity determination code and the previously received authenticity determination code. As described above, the construction site safety management server 100 stores certification acquisition information for each worker in the certification database 111 after the authenticity of the certification is determined.

Therefore, the construction site safety management server 100 uses the certificate acquisition information for each worker stored in the certificate database 111. If the remaining period until the expiration of the validity period of the certificate or each valid period of the equipment registration certificate is less than a specific period, the worker terminal 200 ) can provide a notification message about the expiration of the validity period of the certificate.

In addition, when the construction site safety management server 100 receives a past career registration request message including career information from the worker terminal 200, it extracts career information from the past career registration request message and then stores career information for each worker in the career information database. Save to (112). In this case, the career information may include the number of working days, the type of work, the ordering party (eg, company), the type of the project (eg, civil engineering, architecture, plant, etc.), manager, detailed work type, and the like.

After that, when the construction site safety management server 100 receives the career person search request message from the manager terminal 300, it extracts the worker from the career information database 112 according to the career person search request message, and then guides the career person including the career information provide a message. In this way, the construction site safety management server 100 provides the career information together so that the operator can refer to the worker's project arrangement based on the career information.

If the construction site safety management server 100 is employed by the operator and participates in the project, the worker checks the career and updates the career information for each worker stored in the career information database 112 .

In addition, the construction site safety management server 100 generates a list of workers using the worker information for each worker stored in the worker database 113 and the health checkup object stored in the health checkup database 114, and then the hospital server ( (not shown) provides a health check-up reservation message for reserving a health check-up for workers on the worker list. In this case, the list of workers may include the type of examination for each worker, the date of the next examination, the scheduled examination institution, the desired examination reservation date, and the like.

Thereafter, the construction site safety management server 100 recognizes the examination result document issued by the hospital server (not shown), generates the examination result from the examination result document, and then stores the examination result for each worker in the worker database 113 . Save.

In one embodiment, when the construction site safety management server 100 receives the examination result document issued by the hospital server from the manager terminal 300, it recognizes the examination result document using OCR technology and then corresponds to a predetermined item The contents are extracted and stored in the worker database 113 .

Referring to FIG. 2 , the construction site safety management system includes a construction site safety management server 100 , a manager terminal 300 , and a meteorological agency server 400 . The construction site safety management server 100 includes an accident risk assessment database 120 , a risk assessment standard model 121 , a risk assessment database 122 , a site risk characteristic prediction model 123 , and an accident case database 124 . .

The construction site safety management server 100 generates a risk assessment result for each work type based on the accident risk assessment database 120 and the risk assessment standard model 121 .

The accident risk assessment database 120 stores the accident frequency ratio for each construction type, the accident intensity ratio for each construction type, and detailed information for each accident. In this case, detailed contents for each disaster may include process, cause, accident type, unit work, number of injured persons (death/injury), site location, type of construction, construction amount, and rate of completion. The risk assessment standard model 121 above stores risk factors for each type of work and safety measures for each risk factor.

First, the construction site safety management server 100 corresponds to the keyword in the accident risk assessment database 120 when receiving a keyword corresponding to each of the construction site situation (ie, construction scale, construction type, completion rate, climate, etc.) and work content The accident frequency ratio by construction type, accident intensity ratio by construction type, and detailed contents for each accident are extracted. The above keywords may be determined as a process, an accidental person, an accident type, a unit work content, and the like.

Then, the construction site safety management server 100 calculates a risk assessment result for each work type using the accident frequency ratio for each work type and the accident intensity ratio for each work type.

In this case, the construction site safety management server 100 may calculate the risk evaluation result for each work type through the AI engine or may calculate it through the following [Equation 1] to [Equation 6]. Hereinafter, a process of calculating the risk assessment result for each type of work through [Equation 1] to [Equation 6] will be described.

In [Equation 1], the accident frequency ratio for each work type (Danger_fre_rate) is calculated by the following [Equation 2], and the accident intensity ratio by construction type (Danger_str_rate) is calculated by the following [Equation 3], The weight (Danger_W) determined according to the time of occurrence of each type of accident is assigned a higher weight as the time of occurrence of the accident is closer to the present time for cases where the time of accident does not exceed 3 years from the current time. A predetermined weight (eg, “1”) is assigned to cases in which α is more than 3 years from the present time.

[Equation 2]

Danger_fre_rate = (part_victim / total_victim) × 100

Danger_fre_rate: Accident frequency ratio by construction type,

part_victim: Accident index by construction type,

total_victim: Total disaster index

In [Equation 2], the disaster index (part_victim) and the total disaster index (total_victi) for each work type may be determined by the detailed contents (ie, the number of victims) for each disaster extracted from the risk assessment database 122 .

[Equation 3]

Danger_str_rate

= (part_dead_people_rate × 3) + part_injured_people_rate

Danger_str_rate: Accident intensity ratio by construction type,

part_dead_people_rate: Calculated by [Equation 4] as the death rate by type of work,

part_injured_people_rate: Calculated by [Equation 5] as the rate of injured people by type of work

part_dead_people_rate: rate of deaths by type of work;

part_dead_people: number of deaths by type of work,

total_dead_people: total number of deaths

In [Equation 4], the number of fatalities by type of work (part_dead_people) and the total number of deaths (total_dead_people) may be determined by the details of each disaster extracted from the risk assessment database 122 (ie, deaths among the number of casualties).

[Equation 5]

part_injured_people_rate

= (part_injured_people / total_injured_people) × 100

part_dead_people_rate: Percentage of casualties by type of work;

part_dead_people: number of injured by type of work;

total_dead_people: total number of wounded

In [Equation 5], the number of injured persons (part_dead_people) and the total number of injured persons (total_dead_people) by type of work in [Equation 5] may be determined by the details of each disaster extracted from the risk assessment database 122 (that is, the number of injured among the number of casualties).

The risk evaluation grade for each type of work calculated through [Equation 1] to [Equation 5] above may be as shown in [Table 1] below.

[Table 1]

As described above, when the construction site safety management server 100 determines the risk assessment grade for each work type based on the accident risk assessment database 120 , the risk factor corresponding to the risk assessment grade for each work type in the risk assessment standard model 121 . and safety measures for each risk factor are extracted.

Thereafter, the construction site safety management server 100 generates risk assessment result data by using the risk assessment grade, risk factors, and safety measures for each risk factor, and then stores the risk assessment result data in the risk assessment database.

After generating the risk evaluation result data through the above-described process, the construction site safety management server 100 predicts the risk by reflecting the risk evaluation result data, site information, and the risk evaluation index for each construction cycle based on the site risk characteristic prediction model create data

The above site information may include site address, construction type, construction scale (amount), construction period, master schedule by construction period/building permit information: site location, actual construction start date, main use code name, and the like.

At this time, the site risk characteristic prediction model 123 is the site location, construction type, construction scale, weather, process progress, delay, patrol data by construction type (Patrol Data), accident type patrol data (Patrol Data), compared to all workers The percentage of safety scores for each field worker and work team is stored.

[Equation 6]

ConstructionPeriod_Danger_value = PastPart_Danger_value + weight

ConstructionPeriod_Danger_value: Risk assessment index for each construction cycle,

PastPart_Danger_value: Risk assessment index by past construction type,

weight: site risk characteristic weight

The fixed factors include a site location, a construction type, and a construction scale, and the variable factors include weather information received from the Meteorological Administration server 400 , progress and delay in comparison with a predetermined schedule.

Site nonconformities refer to site nonconformities pointed out by the manager who manages the site. For example, field nonconformities may include non-tightening of safety hooks. As described above, the risk assessment index for each construction cycle is changed by changing the site risk characteristic weight according to fixed factors, variable factors, and site nonconformities.

3 is a network configuration diagram for explaining a construction site work management system according to another embodiment of the present invention.

Referring to FIG. 3 , the construction site work management system includes a construction site work management server 100 and an inspector terminal 500 , and the inspector terminal 500 includes a manager terminal 300 and a monitoring group terminal 600 . . The construction site work management server 100 includes a work permit database 130 and a site subscriber database 131 . 3 may further include a drone (not shown).

The drone captures the monitoring target of the construction site according to the control signal received from the construction site work management server 100 , and then generates scan information and images for the monitoring target and provides it to the construction site work management server 100 . For example, the drone scans a "safety railing" to be monitored for a construction phenomenon, and then provides scan information and an image to be monitored to the construction site work management server 100 .

To this end, the drone irradiates light to the monitoring target of the construction site in the process of scanning the construction site according to the control signal received from the construction site work management server 100 to photograph the monitoring target, and then scans information about the monitoring target and A monitoring target image is generated and provided to the construction site work management server 100 . In this case, the monitoring target may include a helmet of the worker, construction materials, and the like.

In one embodiment, when light is applied while the drone scans the monitoring target when the monitoring target is made of metal, dotted dots of different depths and widths reflect the applied light.

In this case, since the depth and width of the halftone dots formed on the monitoring target are different from each other, the amount of reflected light will be different. Accordingly, the drone provides scan information including information on reflected light on the monitoring target and the monitoring target image to the construction site work management server 100 by using information on the reflected light from the monitoring target.

In another embodiment, when the monitoring target has a pattern generated through the printing process, the drone scans the monitoring target to generate a monitoring target image, and then provides the monitoring target image to the construction site work management server 100 .

In this case, a plurality of halftone dots corresponding to the monitoring code may be inserted in the monitoring target image with a color similar to the pattern of the monitoring target. That is, a plurality of halftone dots corresponding to the monitoring code may be inserted in the monitoring target image as pixel values corresponding to a specific value or more or a specific value or less than the pixel value of the pattern of the monitoring target.

Accordingly, the construction site work management server 100 may extract a plurality of halftone dots by analyzing the pixels of the monitoring target image, and then generate a monitoring code using binary values corresponding to the plurality of halftone dots.

The construction site work management server 100 includes a work permit database 130 and a site subscriber database 131 .

The construction site work management server 100 provides a work permit work procedure to the manager terminal 700 based on worker data. In this case, the work permit database 130 includes a checklist for each work permit, and the on-site subscriber database 131 stores the name and affiliation of each work group leader and the name and affiliation of each worker.

Thereafter, when the work permit is generated from the manager terminal 300 through the work permit work procedure, the construction site work management server 100 generates a list of work permits using the work permit. In this case, the work permit generated by the manager may include the permit number, date, company name, work type by work type, work place, input number of people, work time, work leader, input device, workers, and the like.

Therefore, the construction site work management server 100 is the work content, work place, input number, work time, work leader, input device, worker, work permit target for each work type of work permit (ie, dangerous work permit, general work permit) , create a list of work permits using the type of permit (ie, special, critical, general), supervisor, inspector, etc. This work permit list table is a table of lists for each type of work permit so that the work permit can be checked intuitively.

In this case, when the construction site work management server 100 generates a work permit list table by the manager, it generates a work permit creation list and stores it in the work permit database 130 . After that, the manager assigns tasks to be checked by himself.

If the construction site work management server 100 receives the work permit checklist generated according to the work permit assignment details, it stores the work permit checklist in the work permit database 130 . In this case, the work permit database 130 includes work permit inspection results, inspectors, inspection time, photos, detailed content, and the like.

At this time, when the construction site work management server 100 receives the work stop request message after the nonconformity is found and the work stop is selected through the nonconformity registration procedure, the work stop request message moves to the work place based on the nonconformity It is possible to provide the drone with a control command for photographing the inspection target corresponding to the details of the

For example, if the details of the non-conformity are “unlocked upper safety ring” and the work place corresponds to “the 4th basement in Building 105”, the construction site work management server 100 is located in Building 105, 4th basement. A control command can be given to the drone to move to the catch well and photograph the upper safety ring.

After that, the construction site work management server 100 receives at least one of scan information (eg, information of reflected light from a building material) and a monitoring target image for a monitoring target from the drone, and then scans information and a monitoring target image Generate a monitoring code using at least one of

That is, when the construction site work management server 100 receives both the scan information and the monitoring target image, since the scan information is information of the monitored reflected light, it determines the binary value indicated by the corresponding halftone dot according to the amount of reflected light. and finally, a monitoring code can be generated through the combination of these binary values.

More specifically, when the scan information received from the drone is the information of the reflected light to be monitored, the construction site work management server 100 refers to the binary value table and refers to the binary value according to the number indicated by the shade value corresponding to the information of the light. to decide

That is, the construction site work management server 100 may determine whether the binary value indicated by the shading value corresponding to the light information is 0 or 1 with reference to the binary value table. Then, the building monitoring device 200 determines the monitoring code by sequentially combining binary values.

For example, in the binary value table, the binary value corresponding to the shade value 24 is stored as 1, the binary value corresponding to the shade value 35 is stored as 0, and the construction site work management server 100 is the information of the light. When the shade value corresponding to is 24, the binary value is determined to be 1, and when the shade value corresponding to the light information is 35, the binary value is determined to be 0, so that the monitoring code "1000000" can be generated.

After that, the construction site work management server 100 determines whether the monitoring target corresponding to the monitoring code is the same as the target for which work stop is requested, and if the determination result is the same, analyzes the monitoring target image to determine the reason for the job stop request After verification, the verification result is provided to the manager terminal 300 . Accordingly, the manager terminal 300 may determine whether to stop the work according to the verification result by the construction site work management server 100 .

In the above embodiment, when the monitoring code indicates the worker's helmet and worker's ID, the construction site work management server 100 uses the worker's ID to link with the worker database 113 to provide a safety history for each worker profile. Update history.

On the other hand, when the construction site work management server 100 receives the monitoring target image, it analyzes the monitoring target image and extracts a plurality of dotted dots of different sizes composed of a plurality of dots. Then, the construction site work management server 100 generates a monitoring code using binary values corresponding to a plurality of halftone dots.

That is, the construction site work management server 100 refers to the binary value table, extracts a binary value according to the number of dots configured with half dots, and then generates a monitoring code through a combination of binary values.

After that, the construction site work management server 100 provides a work termination request message to the manager terminal 300 when the work permit inspection is completed, and after the work termination is registered, the closing contents of the work permit are stored in the work permit database 130 . Save.

The inspector terminal 500 selects a work stop or correction request through the nonconformity registration procedure when nonconformities are found during inspection of a specific work on the work permit list table received from the construction site work management server 100 .

If the inspector's terminal 500 is selected to stop work after finding nonconformities, it provides a work stop request message to different inspector terminals. provided to the terminal.

After receiving the work permit work procedure from the construction site work management server 100 , the manager terminal 300 generates a work permit through the work permit work procedure. At this time, the manager terminal 300 generates a work permit by inputting the permit number, date, company name, work type by work type, work place, input number of people, work time, work leader, input device and workers through the work permit work procedure. can

The inspector terminal 500 performs inspection based on the work permit list table received from the construction site work management server 100 .

First, the inspector terminal 500 inputs a detailed check list, photos, and inspection results through the inspection result input procedure for each inspection target item by work type based on the work permit. Thereafter, the inspector terminal 500 may provide any one of a job approval request message, a job stop notification message, and a job partial supplement request message to different manager terminals according to the inspection result.

For example, the inspector's terminal 500 may provide a job approval request message to the inspection result "when it is good", the corresponding work type manager terminal and the worker terminal.

As another example, the inspector's terminal 500 may provide a work stop notification message to the process manager terminal and the worker terminal when the inspection result is “defective”.

As another example, the inspector's terminal 500 may provide a partial task supplementation request message to the process manager terminal and the worker terminal when the inspection result "when supplementing other".

4 is a network configuration diagram for explaining a construction site communication service providing system according to another embodiment of the present invention.

Referring to FIG. 4 , the construction site communication service providing system includes a construction site safety management server 100 and an inspector terminal 500 , and the inspector terminal 500 includes a manager terminal 300 and a monitoring group terminal 600 . do. According to an embodiment, the construction site safety management server 100 of FIG. 4 may further include a drone (not shown).

The drone captures the monitoring target of the construction site according to the control signal received from the construction site work management server 100 , and then creates a monitoring target image and provides it to the construction site safety management server 100 .

To this end, in the process of scanning the construction site according to the control signal received from the construction site work management server 100, the drone irradiates light to the monitoring target of the construction site to photograph the monitoring target, and then scans information about the monitoring target. After creation, the monitoring code is extracted according to the scan information.

In one embodiment, when light is applied in the process of scanning the monitoring target when the monitoring target is made of metal or plastic, the dotted dots of different depths and widths reflect the applied light.

In this case, since the depth and width of the halftone dots formed on the monitoring target are different from each other, the amount of reflected light will be different. Therefore, the drone extracts the monitoring code by using the information of the light reflected from the monitoring target.

More specifically, the drone determines a monitoring code by sequentially combining binary values after determining a binary value according to a number indicated by a shadow value corresponding to light information by referring to a binary value table.

That is, the drone can determine whether the binary value indicated by the shading value corresponding to the light information is 0 or 1 by referring to the binary value table, and determines the monitoring code by sequentially combining the binary values.

For example, in the binary value table, the binary value corresponding to the shade value of 24 is stored as 1, the binary value corresponding to the shade value 35 is stored as 0, and the drone has a shade value of 24 corresponding to the light information. In the case of , the binary value is determined as 1, and when the shadow value corresponding to the light information is 35, the binary value is determined as 0 to generate the monitoring code "1000000".

Then, the drone creates a work site image by taking a picture of the work site including the monitoring target, and then inserts dotted dots of different sizes corresponding to the monitoring code into the work site image and provides it to the construction site safety management server 100 do.

Therefore, if the construction site safety management server 100 corresponds to a predetermined disaster type, the work site image is analyzed to extract the monitoring code, and the monitoring code indicates the worker's helmet and worker's ID. It is possible to update the safety history history in the star profile.

The construction site safety management server 100 provides the unsafe behavior input procedure for each worker stored in the worker database 113 to the inspector terminal 500 . At this time, the unsafe behavior input procedure for each worker is a procedure to input the unsafe behavior of the worker when a behavior corresponding to a predetermined unsafe behavior is found among the actions of the worker working at the construction site. The predetermined unsafe behavior means an action capable of increasing the probability that a disaster type will occur based on the disaster type.

That is, in the unsafe behavior input procedure, suppliers, work teams, workers, accident types, details, photos, etc. can be entered, and the type of accident (e.g., electric shock, crushed, caught, fell, fell, collapsed, If hitting an object, bumping, unbalanced and excessive motion, oxygen deprivation, cutting/cutting/cutting, fire explosion) is selected, a list of unsafe behaviors corresponding to the type of accident is provided, and the list of unsafe behaviors of workers At least one unsafe safety action may be selected.

For example, when “falling” is selected among the disaster types, the construction site safety management server 100 sets the list of unsafe actions corresponding to “falling” as “1) not wearing a safety belt or not fastening a safety ring when working at heights of 2m or more, 2 ) arbitrarily dismantling safety facilities in the fall danger zone”, etc., can be provided to select at least one unsafe behavior that corresponds to the unsafe behavior of the worker.

For another example, when “clogging” is selected among the types of disasters, the construction site safety management server 100 provides “1) unauthorized entry within the working radius of the equipment” as a list of unsafe behaviors corresponding to “clogging” to protect workers’ safety. At least one unsafe behavior corresponding to the unsafe behavior may be selected.

As another example, the construction site safety management server 100 provides “1) unauthorized entry into a confined space” as a list of unsafe behaviors corresponding to “oxygen deficiency” when “oxygen deficiency” is selected among the types of disasters. At least one unsafe behavior corresponding to the unsafe behavior may be selected.

Then, when the construction site safety management server 100 is corrected by the partner company based on the corrective action form, corrective action information (eg, partner company, work team) from the manager terminal 300 of the inspector terminal 500 , disaster type, and before and after actions) are received and stored in the action database 410 . Conversely, the construction site safety management server 100 provides a procedure for canceling registration of nonconformities when it is determined that the content pointed out as nonconformity is not appropriate.

To this end, when the construction site safety management server 100 receives an image to be monitored from the drone, it analyzes the image to be monitored and extracts a plurality of dotted dots of different sizes composed of a plurality of dots. Then, the construction site safety management server 100 extracts the monitoring code using binary values corresponding to a plurality of dotted dots.

That is, the construction site safety management server 100 refers to the binary value table, extracts a binary value according to the number of dots configured with half dots, and then extracts a monitoring code through a combination of binary values.

More specifically, the construction site safety management server 100 may determine whether the binary value corresponding to the halftone point is 0 or 1 according to the number of points configured with the halftone point by referring to the binary value table. Then, the building monitoring device 200 determines the monitoring code by sequentially combining binary values.

For example, when one halftone dot made of four dots and six halftone dots made of eight dots are extracted from the monitoring target image, the construction site safety management server 100 sets a binary value corresponding to the four dot halftone dots to 1 and creates a monitoring code “1000000” by recognizing a binary value corresponding to a halftone dot consisting of 8 dots as 0.

For another example, when two halftone dots made of 6 dots and 3 halftone dots made of 8 dots are extracted from the monitoring target image, the construction site safety management server 100 returns a binary value corresponding to the halftone dots made of 6 dots. It is recognized as 1 and the binary value corresponding to the halftone dot composed of 8 dots is recognized as 0, and the monitoring code “11000” is generated.

As described above, after generating the monitoring code, when the monitoring code indicates the worker's helmet and worker's ID, the construction site safety management server 100 uses the worker's ID to link with the worker database 113 for each worker You can update your safety history history in your profile.

When the inspector terminal 500 receives the unsafe behavior input procedure for each worker from the construction site safety management server 100, the supplier, the work team, the worker, the accident type, details, photos, etc. are received through the unsafe behavior input procedure for each worker. do.

Provided to the site safety management server (100).

Thereafter, the inspector terminal 500 and the manager terminal 300 generate a safety inspection log using the unsafe behavior and input information collected through the unsafe behavior input procedure. At this time, the inspector terminal 500 and the administrator terminal 300 reflect the unsafe behavior entered by the manager among the inspectors in the safety inspection log of the worker, and the corrective actions entered by the inspector among the inspectors are reflected in the safety inspection log .

In addition, when the manager terminal 300 of the inspector terminals 500 receives details, photos, and safety accident-related contents through the safety reporting procedure from the construction site safety management server 100, it determines whether to adopt a safety report and construction Provided to the site safety management server (100).

Accordingly, the construction site safety briefing server 100 stores the contents of the safety report in the worker database 113 when it is adopted as a safety report, and the contents of the safety report (that is, the site, whether or not to adopt, the type of disaster, details contents, photos, etc.) are stored in the safety newspaper database 411 .

After that, the manager terminal 300 of the inspector terminals 500 generates a corrective action sheet to prevent the occurrence of the corresponding disaster type based on the disaster type matched through the disaster type matching process, and then writes the corrective action to the manager terminal ( 300) is provided.
