Description

  The present invention relates to a safety degree determination program, a safety degree determination method, and a safety degree determination device.

  At the site of work at height, the worker wears safety equipment and performs work so that the fall and fall of the worker can be avoided as much as possible. In the past, the use of safety belts was entrusted to workers, but in recent years there is known a technology for collecting and managing the use conditions of the safety belts of each worker by a sensored safety belt having a communication function . For example, the safety band with sensor determines whether the hook is in use or not and transmits it to the management server. The management server specifies an operator whose hook is disengaged according to the information received from each worker's safety band with a sensor, and outputs an alarm or the like.

  Hereinafter, embodiments of a safety degree determination program, a safety degree determination method, and a safety degree determination device disclosed in the present application will be described in detail based on the drawings. The present invention is not limited by this embodiment. Moreover, each Example can be combined suitably within the range without contradiction.

[overall structure]
FIG. 1 is a diagram illustrating an example of an entire configuration of a system according to a first embodiment. As shown in FIG. 1, this system includes a safety belt 1 worn by a worker working at a high place, a smartphone 3 carried by the worker, and a sensor 5 worn by the worker on a part of the body; The management terminal 7 possessed by the on-site supervisor and the security level determination device 10 providing the cloud service are connected in a wirelessly communicable manner. Here, the worker wears one or more safety belts 1 and works at a high place, and the on-site supervisor manages the work content of the worker, the progress, and the safety of each worker. Although an example in which the safety band 1 and the sensor 5 are separate housings will be described, the present invention is not limited to this. The safety band 1 may have the sensor 5.

  Here, an example of a site where each worker works will be described. FIG. 2 is a diagram illustrating an example of a work site according to the first embodiment. As shown in FIG. 2, in this embodiment, as an example, construction of a 31-storey building and the like will be described as an example. In such constructions, anchors such as pipes and columns are used to construct scaffolds for workers to work with. In the example of FIG. 2, a scaffold is comprised by 17 pipes from the 1st pipe (P1) to the 17th pipe (P17). Then, each worker climbs while changing the safety band 1 from the ground to the work place. For example, the worker moves from the ground to the work place while changing the safety band 1 to each of the pipes P1, P2, P6, P7, P8, P12, P13, P14, and P15.

  Returning to FIG. 1, the safety band 1 is a determination function such as a sensor that determines whether or not it is safely attached to a support or a fixed object such as a scaffold or a column fixed to a work site, and the determination result It is an example of a safety hook etc. which have a transmitting function which transmits attachment information to safety degree judging device 10.

  For example, the safety band 1 suppresses the determination function, the tension sensor, and the transmission function when stored in the storage unit held by the worker. In addition, the safety band 1 transmits an on signal to the safety degree determination device 10 when the hook portion is attached to the work site, and the safety degree determination device when the hook portion is not attached to the work site Send to 10

  The smartphone 3 is an example of a communication device having a near field communication such as Bluetooth (registered trademark) or a wireless communication function. For example, when the smartphone 3 receives a warning signal, a warning message, and the like from the safety degree determination device 10, the smartphone 3 reports a warning by vibration, voice, and the like.

  The sensor 5 is an example of a measuring device that senses environmental information related to the work environment in which the worker is working and transmits the sensed information to the safety degree determination device 10. For example, the sensor 5 measures the position information (coordinates) of the worker, the height at which the worker is located, acceleration data of the worker, and the like, and transmits the measured data to the safety degree determination device 10. Note that various types of sensing and the like can adopt a known method such as GPS (Global Positioning System), and the transmission interval can be arbitrarily set, but for example, transmission is performed every one second.

  The management terminal 7 is an example of a computer device used to manage a work plan of a work site, information on workers, work time, progress, etc., and is, for example, a tablet terminal or a smartphone. The management terminal 7 receives and displays each information such as a warning, a management screen, and a work progress from the safety degree determination apparatus 10, and notifies the on-site supervisor of the information.

  The safety degree determination device 10 is an example of a computer device that transmits and receives various information by wireless communication of another device, and integrates and manages attachment information and environment information of each worker, and manages past work history and the like.

  In such a system, the safety degree determination device 10 is provided with a safety band 1 having a transmission function for transmitting attachment information indicating whether the worker is attached or not attached to the work site, and the position information of the safety band The history information including the attachment information in the position information is acquired. Then, the safety degree determination device 10 specifies the length of time during which the safety band 1 is not attached among the history information. After that, the safety degree determination device 10 determines the degree of safety of the worker based on the length of time allowed for a state where the safety band 1 is not attached at the work site and the length of time.

  For example, the safety degree determination apparatus 10 compares the worker's past work history, the work novice's work history, the reference information such as the work history of the skilled person (reference value), and the current work history of the worker, It is determined whether or not the off-time of the safety band 1 different from normal is occurring. Then, when the safety degree determination device 10 detects the off state of the safety band 1 different from the normal state, the safety degree determination device 10 determines that the worker is in a high risk work state. Thereafter, the safety degree determination apparatus 10 transmits a warning to the smartphone 3 of the corresponding worker or the other smartphone 3 in the vicinity of the corresponding worker.

  As described above, the safety degree determination apparatus 10 can identify a worker who is performing a task different from a normal task by using another objective index, and thus detects a worker with a high task risk. can do.

[Function configuration]
Subsequently, the functional configuration of each device shown in FIG. 1 will be described. The safety band 1 has the same function as the known safety band 1 having a communication function, the smartphone 3 has the same function as a general communication device, and the sensor 5 is a general sensor and The management terminal 7 has the same function and has the same function as a general computer device, so the detailed description will be omitted. Here, the safety degree determination device 10 having a function different from a general function will be described.

  FIG. 3 is a functional block diagram of the functional configuration of the safety degree determination device 10 according to the first embodiment. As shown in FIG. 3, the safety degree determination device 10 includes a communication unit 11, a storage unit 12, and a control unit 30.

  The communication unit 11 is a processing unit that controls communication between other devices, and is, for example, a communication interface or a wireless interface. For example, the communication unit 11 receives the attachment information from the safety band 1 of each worker, receives the environment information from the sensor 5, and transmits a warning to the smartphone 3 or the management terminal 7.

  The storage unit 12 is an example of a storage device that stores programs and data, and is, for example, a memory or a hard disk. The storage unit 12 includes a pipe structure DB 13, a worker DB 14, a history information DB 15, a past history DB 16, a beginner technology DB 17, and a model technology DB 18.

  The pipe structure DB 13 is a database that stores information on fixed objects created at the work site. Specifically, the pipe structure DB 13 stores information on pipes used by a worker for movement.

  FIG. 4 is a diagram showing an example of information stored in the pipe structure DB 13. As shown in FIG. 4, the pipe structure DB 13 stores “pipe name, start point, end point, distance” in association with one another. The “pipe name” is an identifier for identifying a pipe. The "start point" is position information indicating the start position of the pipe, and the "end point" is position information indicating the end position of the pipe. "Distance (length)" is information indicating the length of the pipe. The example of FIG. 4 shows that the pipe P1 having a length of 10 m is installed at the positions of "35.4 / 139/0" to "35.4 / 140/5". The information stored here is updated by a manager or the like.

  The worker DB 14 is a database that stores information on workers. FIG. 5 is a diagram showing an example of information stored in the worker DB 14. As illustrated in FIG. 5, the worker DB 14 stores “device ID, worker ID, worker name, years of experience, contact information” in association with one another. The “device ID” is an identifier for identifying the safety band 1 used by the worker. The “worker ID” is an identifier for identifying a worker. The “worker name” is the name of the worker, and the “year of experience” is the year of experience of the worker. The “contact information” is a contact information of the worker, and is, for example, an email address, a telephone number, an SNS (Social Networking Service) ID, a Bluetooth (registered trademark) ID, or the like.

  In the example of FIG. 5, Patent Taro who has 30 years of experience uses the safety band 1 of “D1”, and indicates that the contact is “XXX”. In addition, "sensor ID" which identifies the sensor 5 which a worker carries can also be matched and memorize | stored.

  The history information DB 15 is a database for storing past information acquired from the worker's safety band 1 and the sensor 5. FIG. 6 is a diagram showing an example of information stored in the history information DB 15. As shown in FIG. As shown in FIG. 6, the history information DB 15 displays “No, worker ID, pipe name, GPS of start time, GPS of end time, hook status, start time, end time, required time, movement distance, “Remark” is stored in association with it.

  “No” is an identifier for identifying a record (information) of history information, “worker ID” is an identifier for identifying a worker, and “pipe name” is a pipe through which the worker passed when moving It is an identifier to identify. “GPS at start time” is position information of the change start time of the hook state, and “GPS at end time” is position information of the change end time of the hook state. The “hook state” is information indicating whether or not the safety band 1 is properly attached to a pipe or the like. “On” is stored when normally attached, and “off” is stored when not normally attached. Ru.

  The “start time” is the time when the change of the state of the hook (safety band 1) is started, and the “end time” is the time when the change of the state of the hook (safety band 1) ends. The "required time" is the time required for moving the pipe, that is, the time when the state of the safety band 1 is maintained. The “moving distance” is a distance traveled by the worker, can be specified by the distance (length) of the pipe, and can also be calculated by the difference of position information by GPS. “Remarks” is information input by the worker of the smartphone 3.

  The first line in FIG. 6 shows that the worker A is working on the 10 m pipe P1 located at “(35.4 / 139/0) − (35.4 / 140/5)” from “8:00:00” to “8: The safety band 1 is turned on until 01:00 ", which indicates that movement has occurred in one minute. The first line corresponds to the start of work. Note that the history information DB 15 can manage the history information by dividing each worker or each work content. For example, the history information DB 15 separately manages the history information of the work S1 (wall painting) of the worker A and the history information of the work S2 (attaching the outer wall), and the history information of the work S1 (wall painting) of the worker B It is possible to manage the history information of the work S2 (attaching the outer wall) separately.

  The past history DB 16 is a database that stores past history information of each worker. Specifically, the past history DB 16 divides the work content of each worker and stores the average value of the past history information. The stored information is the same as that shown in FIG. Here, as an example of the average value, the average value of the required time and the average value of the movement distance correspond.

  The beginner technology DB 17 is a database for storing past history information of an untrained worker (beginner) who is not accustomed to work with a work experience year less than or equal to a threshold, such as three years or less after joining the company. Specifically, the novice technology DB 17 stores the work history of the beginner and the assumed history information by dividing the content into work contents. For example, an average value of past history information of a plurality of beginners can be estimated as a beginner's work history and stored in the beginner technology DB 17. Here, as an example of the average value, the average value of the required time and the average value of the movement distance correspond. The stored information is the same as that shown in FIG. 6 and can also be generated by the administrator or the like or the safety level determination device 10. Also, the work content can be identified by a work content ID or the like.

  The model technology DB 18 is a database that stores past history information of a model worker with a certain technical level, such as a worker whose generated accident is less than or equal to a threshold. Specifically, the model technology DB 18 stores the work history of the model worker and assumed history information by dividing the work content into groups. For example, an average value or the like of past history information of a plurality of model workers can be estimated as a model worker's work history and stored in the model technology DB 18. Here, as an example of the average value, the average value of the required time and the average value of the movement distance correspond. The stored information is the same as that shown in FIG. 6 and can also be generated by the administrator or the like or the safety level determination device 10. Also, the work content can be identified by a work content ID or the like.

  The control unit 30 is a processing unit that controls the entire safety degree determination apparatus 10, and is, for example, a processor. The control unit 30 includes a collection unit 31, a determination unit 32, and a warning unit 35. The collection unit 31, the determination unit 32, and the warning unit 35 are an example of an electronic circuit such as a processor or an example of a process executed by the processor. The collection unit 31 is an example of an acquisition unit, and the determination unit 32 is an example of a specification unit and a determination unit.

  The collecting unit 31 detects the position information of the safety band 1 and the position information from the safety band 1 or the sensor 5 having a transmission function for transmitting attachment information indicating whether the worker is attached or not attached to the work site. It is a processing unit that collects history information including attachment information.

  For example, when the hook status and the position information are received from the safety band 1 or the sensor 5 of the device ID “D1” used by the worker with the worker ID “A”, for example, the collection unit 31 starts the reception time at this time While determining with time, it is determined that the positional information at this time is GPS of start time. Then, the collection unit 31 stores the start time, the hook state, and the GPS at the start time in the history information DB 15 in association with each other.

  Subsequently, when the collection unit 31 receives the changed hook state and the position information from the safety band 1 or the sensor 5, it determines that the reception time at this time is the end time, and the position information at this time is the end time Determined as GPS. Then, the collection unit 31 stores the end time and the GPS of the end time in the history information DB 15 in association with each other.

  Furthermore, the collection unit 31 identifies a pipe name corresponding to the GPS at the start time and the GPS at the end time from the pipe structure DB 13 and stores the pipe name in the history information DB 15 in association with each of the above information. The collection unit 31 also stores the difference between the start time and the end time in the history information DB 15 as the required time. In addition, the collection unit 31 calculates an absolute value of a difference between the GPS at the start time and the GPS at the end time, and stores the absolute value as the movement distance in the history information DB 15.

  For example, the collection unit 31 can identify the time zone in which the safety zone 1 is off or on based on the safety zone 1 or the attachment information received from the sensor 5 or the like. FIG. 7 is a diagram for explaining the attachment information. As shown in FIG. 7, the safety band 1 transmits ON information to the safety degree determination device 10 when attached to the pipe P1, and transmits OFF information to the safety degree determination device 10 when removed from the pipe P1.

  Therefore, the collection unit 31 can calculate the length of time during which the safety band 1 is off from the difference between the time when the safety band 1 is turned off and the time when the safety band 1 is turned on. Similarly, the collection unit 31 can calculate the distance traveled by the worker with the safety band 1 turned off from the difference between the position information when the safety band 1 is turned off and the position information when the safety band 1 is turned on.

  As described above, each time the information is received from the safety band 1 or the sensor 5, the collection unit 31 generates history information and stores the history information in the history information DB 15. The end time GPS is stored as the start time GPS of the next record, and the end time is stored as the start time of the next record.

  Determination unit 32 has initial determination unit 33 and standard determination unit 34, selects a reference work history, compares the current work history of the worker with the reference work history, and It is a processing unit that determines safety.

  The initial determination unit 33 is a processing unit that determines the safety of the worker by comparing the history information of the worker with the beginner technology for a predetermined number of days after the start of the work at the work site. That is, the initial judgment unit 33, when working at a new work site and unfamiliar at a work site, has a past history and work of the corresponding work content stored in the beginner technology DB 17 for a predetermined period such as two days from the start of the work. The worker's safety is determined by comparing with the person's history information.

  For example, when the initial determination unit 33 accumulates the history information of the worker A who is performing work content S1 (work S1) for a predetermined time (for example, one hour), the predetermined time of the past history of the beginner corresponding to the work content S1 The minutes are extracted from the beginner technology DB 17. Then, the initial determination unit 33 compares the history information of the worker A with the past history of the beginner technology, and when the total time of OFF of the safety band 1 is longer than the history information of the worker A, the worker A Is determined to be a high-risk work state. That is, the initial determination unit 33 determines that the safety of the worker A is dangerous if the time when the worker A turns off the safety belt 1 is longer than the beginner on average.

  As another example, the initial determination unit 33 can also determine by focusing on each record in which the hook state is off. For example, the initial determination unit 33 specifies the required time (off time) in which the safety band 1 is off in the pipe P1 from the history information of the worker A, and specifies the corresponding past history from the beginner technology DB 17. Then, when the off time of the history information of the worker A is longer, the initial determination unit 33 can also determine that the worker A is in a high risk work state. That is, when the off time of the worker A is long for a certain pipe, the initial determination unit 33 determines that the safety of the worker A is dangerous because the possibility of working with the pipe off is high.

  Further, the initial determination unit 33 specifies the movement distance when the safety band 1 is off in the pipe P1 from the history information of the worker A, and specifies the corresponding past history from the beginner technology DB 17. Then, when the movement distance of the worker A is longer, the initial determination unit 33 can also determine that the worker A is in a high risk work state. That is, when the movement distance of worker A in the off state is long with respect to a certain pipe, the initial determination unit 33 determines that the safety of worker A is dangerous because the possibility of working with it off is high. Do.

  Other than these, the initial determination unit 33 can also determine the past history etc. by converting it into a graph. Specifically, the initial determination unit 33 extracts the past history of the beginner from the beginner technology DB 17, and reads a record in which the hook state is off from the past history of the beginner. Subsequently, the initial determination unit 33 plots “moving distance (Δd), required time (Δt), altitude (GPS altitude)” of each read record as a data pair (measurement point data) on a graph.

  FIG. 8 is a diagram for explaining an example of determination of safety. As shown in FIG. 8, the initial determination unit 33 plots each measurement point data (black circle) extracted from the past history of the beginner. Similarly, the initial determination unit 33 extracts the history information of the worker A from the history information, and reads the record in which the hook state is off. Subsequently, the initial determination unit 33 plots “moving distance (Δd), required time (Δt), altitude (GPS altitude)” of each read out record as measurement point data (white circle) on a graph.

  Here, the initial determination unit 33 draws a reference curve based on the measurement point data of the beginner, and the operator A's test results are obtained depending on whether the measurement point data of the worker A is inside or outside the reference curve. Determine stability. For example, when the measurement point data of the worker A is equal to or more than the threshold value inside the reference curve, as in the white circle 8-1, the initial determination unit 33 has a short movement distance in the state where the safety band 1 is out. It is judged that the time is short and the safety state is judged. On the other hand, when the measurement point data of the worker A is equal to or more than the threshold outside the reference curve as indicated by the white circle 8-2, the initial determination unit 33 has a long movement distance in the state where the safety band 1 is out It is judged that the time is long, and it is judged as the dangerous state.

  In addition, the initial determination unit 33 can also place more importance on measurement point data having a high altitude. For example, when there are a large number of measurement point data of worker A whose height is less than the threshold outside the reference curve, the initial determination unit 33 determines that the worker's risk is a caution level, and the height is a measurement point at or above the threshold When there is a lot of data, it is possible to judge the worker's risk as the immediate attention level and to classify the level of the risk.

  The initial determination unit 33 can also perform the following processing on measurement point data outside the reference curve. For example, the initial determination unit 33 compares the measurement point data in descending order of altitude. Further, when Δd is separated by a predetermined value or more from the reference curve, the initial determination unit 33 determines that the danger is more dangerous because the moving distance in the state in which the safety band 1 is out is long. Further, when Δt is separated by a predetermined value or more from the reference curve, the initial judgment unit 33 may be taking a break because the time in the state in which the safety belt 1 is out is long, but it may be dangerous during gusts judge.

  The initial determination unit 33 outputs the determination result of each determination method described above to the warning unit 35. The determination methods can be arbitrarily combined.

  The standard determination unit 34 is a processing unit that determines the safety of the worker by comparing the history information of the worker with the past history or the model technology after the work on the work site has passed a predetermined number of days. That is, for the work after getting used to the work site, the standard judgment unit 34 compares the past history of the corresponding work content of the worker stored in the past history DB 16 with the history information of the worker to ensure the safety of the worker. Determine the gender. Similarly, for the work after getting used to the work site, the standard judgment unit 34 compares the model technology of the corresponding work content stored in the model technology DB 18 with the history information of the worker to obtain the safety of the worker. judge.

  For example, the standard determination unit 34 can specify the worker's current physical condition and the like by comparing with the worker's past history. More specifically, when the off time of the worker is long compared to the past history, the standard determination unit 34 can suspect that the physical condition of the current worker is bad, and quickly detects the dangerous state of the worker can do.

  For example, the standard determination unit 34 can determine the technical skill of the worker in addition to the safety of the worker by comparing with the exemplary technique. More specifically, the standard judgment unit 34 can judge that the technical ability of the worker is high when the safety band 1 is off and the working time is short as compared with the exemplary technique. Further, the standard judgment unit 34 can judge that the worker is a prudent worker when the working time is long, although the safety zone 1 is not turned off in comparison with the exemplary technique. In addition, the standard determination unit 34 can determine that the technical ability of the worker is low when the safety band 1 is off for a long time and the operation time is long as compared with the exemplary technique.

  Then, the standard determination unit 34 outputs the determination result of the safety of the worker to the warning unit 35. In addition, since the determination method can use the same method as the initial determination part 33, detailed description is abbreviate | omitted. In addition, even if the work at the work site is before a predetermined number of days, the determination by the standard determination unit 34 can also be executed.

  The warning unit 35 is a processing unit that reports a warning when a dangerous worker is detected. For example, when notified by the initial determination unit 33 or the standard determination unit 34 that the worker A is in danger, the warning unit 35 communicates with the smartphone 3 of the worker at the radius 5 m of the worker A, the management terminal 7 and To notify that worker A is in danger. After that, when the safety of the worker A is not improved, the warning unit 35 works while the worker A who is dangerous around the worker is working on the smartphone 3 of the worker A who is present at a radius of 10 m and the management terminal 7. Inform that it is. In this manner, the warning unit 35 gradually widens the transmission range to notify the surroundings that the worker is in danger.

  In addition, the warning unit 35 can also transmit a warning to the effect that the worker A's smartphone 3 should work with caution when the safety band 1 of the worker A is in the on state. Although the warning can be transmitted when the safety band 1 of the worker A is in the off state, it is preferable that the safety band 1 is in the on state in order to reduce the risk at the time of the warning. In addition, the warning unit 35 can notify the warning by dynamically changing the transmission range or the message content according to the danger level.

[Flow of processing]
FIG. 9 is a flowchart showing the flow of processing. As shown in FIG. 9, when the determination section 32 of the safety level determination apparatus 10 is less than a predetermined number of days from the start of work (S101: Yes), the beginner technology is selected (S102), and the predetermined number of days from the start of work is exceeded. (S101: No), the past history or model technology is selected (S103).

  Subsequently, the determination unit 32 generates measurement point data and a reference curve using the data selected in S102 or S103 (S104). Further, the determination unit 32 reads the history information of the worker collected by the collection unit 31 from the history information DB 15 (S105), and generates measurement point data of the worker (S106).

  Thereafter, the determination unit 32 compares the data plots obtained by plotting the measurement point data (S107), and determines whether the measurement point data of the worker is inside the reference curve (S108).

  Then, when it is determined that the measurement point data of the worker is inside the reference curve (S108: Yes), the determination unit 32 determines that the state of the worker is in the safe state (S109).

  On the other hand, when it is determined that the measurement point data of the worker is not inside the reference curve (S108: No), the determination unit 32 determines that the state of the worker is a dangerous state (S110). Then, the warning unit 35 transmits a warning to the workers around the worker who is in a hazardous operation (S111).

[effect]
As described above, the safety degree determination apparatus 10 can detect a worker with a high operation risk without depending on the worker's habit or skill using the qualitative reference index. Further, since the safety degree determination apparatus 10 can determine the safety by dynamically changing the reference index, it is possible to execute the stability following the state of the work, and the determination accuracy can be improved. Further, the safety degree determination apparatus 10 can specify the technical level of the worker, and can provide the management terminal 7 with information useful for the worker's education and the like.

  By the way, although the example which determines a worker's safety was explained in Example 1, it is not limited to this, and it is also possible to detect an operation different from the work schedule or an abnormal operation. Therefore, in the second embodiment, a specific example will be described in which another determination different from the safety is performed using the history information of the worker.

  FIG. 10 is a diagram for explaining an example of setting a work plan by the manager. As shown in FIG. 10, the safety degree determination apparatus 10 can display the pipe structure of the work site as a 3D (three-dimensional) map, and can receive an input of the work plan on the 3D map. In FIG. 10, the safety degree determination apparatus 10 indicates that the two workers each received a work plan for performing wall painting for three hours using the pipes P10 and P11. In addition, the safety degree determination device 10 indicates that the two workers have received a work plan for attaching the outer wall for 5 hours using the pipes P15, P16, and P17.

  Then, the safety degree determination apparatus 10 can review the work plan by comparing the received work plan with the collected history information of the workers. FIG. 11 is a diagram for explaining the identification of an operation having a long operation time. When the history information shown in FIG. 11 is collected, the safety degree determination device 10 uses No. 1 and No. 2 using the pipes P10 and P11. 13 to No. 22 history information is specified, and it is detected that the working time in between is 5 hours or more. Thereafter, the safety degree determination apparatus 10 determines that the work of the worker A is longer than the work plan since the work plan (wall coating) using the pipes P10 and P11 received in advance is five hours per person.

  Then, the safety degree determination apparatus 10 notifies the management terminal 7 or the like that the work using the pipes P10 and P11 takes five hours or more. By doing this, the administrator can review the wall-painting work plan. In addition, the safety degree determination apparatus 10 visually displays the difference between the work plan and the actual work by displaying the actual work time of the worker A and the worker B who performed the wall painting work as a pie chart or the like. The administrator can be notified.

  FIG. 12 is a diagram for explaining the identification of an abnormal operation. Here, an example in which the safety degree determination apparatus 10 collects history information shown in FIG. 12 will be described. Here, an example of displaying all collected history information is illustrated, but the process described later is executed each time a record is stored.

  Specifically, as shown in FIG. When 12 pieces of history information are collected, it is specified that the required time is 60 minutes, which is equal to or more than a threshold (for example, 1 minute), although the hook state is off. In this case, the safety degree determination device 10 determines that there is a possibility that the safety band 1 is not properly installed, and a message such as "Don't you forget to install the safety band 1" , Send to the smartphone 3 of the corresponding worker or the smartphone 3 in the vicinity.

  In addition, the safety degree determination device 10 has no. When 32 pieces of history information are collected, the required time is 60 minutes, which is more than the threshold (for example 1 minute), and the movement distance is 100 m, which is more than the threshold (for example 15 m) Identify In this case, the safety degree determination device 10 determines that there is a possibility that the work site is not present, and sends a message such as "Do you work at the work site" on the smartphone 3 of the corresponding worker or the smartphone 3 in the vicinity Send.

  In addition, the safety degree determination device 10 has no. When 43 pieces of history information are collected, No. It is determined that the continuity with the history information of 42 is not correct. For example, the safety degree determination device 10 is No. No. 42 is the history information of the pipe P14. Since 43 is the history information of the pipe P8, it is determined that the movement from P14 to P8 which can not be moved directly is occurring. In this case, the safety degree determination apparatus 10 transmits a message such as "Do you not move by skipping a pipe?" To the smartphone 3 of the corresponding worker or the smartphone 3 in the vicinity.

  Thus, the safety level determination device 10 can also detect an operation different from the operation schedule or an abnormal operation. Therefore, it can be useful for reviewing work plans and identifying workers with low awareness of safety.

  Although the embodiments of the present invention have been described above, the present invention may be implemented in various different modes other than the above-described embodiments. Therefore, different embodiments will be described below.

[environment]
For example, the safety degree determination apparatus 10 can determine the safety after giving a weight to the required time, the movement distance, and the like in which the safety zone 1 is off according to the work environment. For example, on a windy day or a rainy day, the safety degree determination device 10 doubles the required time and the movement distance for the history information in which the safety zone 1 is off and the altitude is higher than the threshold, and data plot (graph) Can also be generated. In addition, on a windy day or a rainy day, it is possible to generate a data plot (graph) by doubling the required time and the movement distance for work (history information) on a scaffold of slippery material. By doing this, the safety degree determination apparatus 10 can make a determination with emphasis on high-level work to be particularly careful in the case of bad weather.

  In addition to the weather, the physical condition of the worker can be received in advance and used. For example, when the physical condition is not good, the safety zone 1 is off and the altitude is a threshold or more for the history information, the required time and the movement distance are doubled to generate a data plot (graph). Note that the threshold described in each embodiment can be arbitrarily set and changed.

[Years of experience]
In addition, the safety degree determination device 10 can determine the safety using different criteria (history information) for each of the years of experience of the worker. As described above, by dynamically changing the determination criteria according to the years of experience of the worker, it is possible to accurately determine the safety based on the determination criteria according to the years of experience.

[pipe]
In the above embodiment, it is possible to clearly separate and manage the footsteps on which the worker walks and the pipes connecting the safety band 1. In that case, the data structure of the pipe structure DB 13 can be processed in the same manner as each of the above-described methods by configuring the scaffold to be specified by the pipe.

[system]
The processing procedures, control procedures, specific names, and information including various data and parameters shown in the above documents and drawings can be arbitrarily changed unless otherwise specified.

  Further, each component of each device illustrated is functionally conceptual, and does not necessarily have to be physically configured as illustrated. That is, the specific form of distribution and integration of each device is not limited to the illustrated one. That is, all or part of them can be configured to be functionally or physically dispersed and integrated in arbitrary units in accordance with various loads, usage conditions, and the like. Furthermore, all or any part of each processing function performed in each device may be realized by a CPU and a program analyzed and executed by the CPU, or may be realized as wired logic hardware.

  The communication interface 10a is a network interface card or the like that controls communication of another device. The HDD 10 b is an example of a storage device that stores programs, data, and the like.

  Examples of the memory 10 c include a random access memory (RAM) such as a synchronous dynamic random access memory (SDRAM), a read only memory (ROM), and a flash memory. Examples of the processor 10 d include a central processing unit (CPU), a digital signal processor (DSP), a field programmable gate array (FPGA), and a programmable logic device (PLD).

  Further, the safety degree determination apparatus 10 operates as an information processing apparatus that executes a service providing method by reading and executing a program. That is, the safety degree determination apparatus 10 executes a program that executes the same function as the collection unit 31, the determination unit 32, and the warning unit 35. As a result, the safety degree determination apparatus 10 can execute a process that performs the same function as the collection unit 31, the determination unit 32, and the warning unit 35. Note that the program referred to in the other embodiments is not limited to being executed by the safety level determination device 10. For example, when the other computer or server executes the program, or when they cooperate to execute the program, the present invention can be applied similarly.
