BRIEF DESCRIPTION OF THE DRAWINGS

[0014] Figure 1 It is a flow chart of the construction safety monitoring method.

[0015] Figure 2 It is a module flow chart of the construction safety monitoring method. DETAILED DESCRIPTION

[0016] In order to make the purpose, technical solutions and advantages of this application more clear, the following Figure 1-Figure 2It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0017] The embodiments of the present application are further described in detail below in conjunction with the drawings in the specification.

[0018] The present application discloses a construction safety monitoring method, referring to Figure 1 The method flow of the construction safety monitoring method includes the following steps: Step S100: Obtain the component reading position and component number of the positioning components installed on the limbs and head of the worker.

[0019] The positioning component is a module component that can transmit information about the position in space in real time, such as a position sensor. By setting the positioning component on the limbs and head of the staff, the approximate position of the staff can be determined, which is convenient for subsequent analysis; the positioning components set on the limbs of the staff can be installed on the work clothes respectively, and the positioning component on the head can be installed on the safety helmet; the component reading position is the position point of the positioning component in space, and the component number is the number of the positioning component. Different numbers indicate different corresponding personnel.

[0020] Step S101: Determine the component monitoring personnel corresponding to the component number and the personnel's own parameters according to the preset personnel matching relationship.

[0021] The component monitoring personnel refers to the personnel currently being monitored. Different personnel correspond to different component numbers, so the personnel can be identified by the component number; the personnel's own parameters refer to the parameter values ​​of the personnel corresponding to the component number, and the parameters include height, body shape, etc., that is, the human body model of the staff can be effectively constructed through the personnel's own parameters. The personnel matching relationship between the three is determined by the management personnel who obtains and enters the information of each staff member in advance.

[0022] Step S102: Perform posture simulation based on the personnel's own parameters and the reading positions of each component to determine the personnel's working posture.

[0023] The working posture of the personnel is the current posture of the personnel. The positions of the positioning components under different personnel are different, and the corresponding postures are also different. Therefore, the posture of the personnel can be determined by inputting the component reading position into the model corresponding to the human body. The method of determining the posture of the personnel by the position of the limbs and head can refer to VR technology. It is a conventional technical means for personnel in this field and will not be elaborated here.

[0024] Step S103: Determine the personnel to perform the task in a preset task database according to the current time point and the component monitoring personnel.

[0025] The personnel execution task is the task currently being performed by the component monitoring personnel, including erecting steel frames, etc. The task database stores the operation task information of each staff member who is working.

[0026] Step S104: determining a set of dangerous postures corresponding to a person performing a task according to a preset posture matching relationship.

[0027] The dangerous posture set is a set of postures that can be identified as inaccurate and dangerous when the current personnel are performing the task. Different personnel need to perform different operations when performing tasks, so the corresponding dangerous posture sets are also different. The posture matching relationship between the two is determined by the staff through multiple experiments in advance, which will not be elaborated here.

[0028] Step S105: Determine whether the operator's working posture is in a dangerous posture set.

[0029] The purpose of the judgment is to effectively monitor the current posture of the staff member to determine whether there are any safety hazards.

[0030] Step S1051: If the operator's working posture is in the dangerous posture set, an abnormal working signal is output.

[0031] When a person's working posture is in a set of dangerous postures, it means that there is a safety hazard in the current posture of the worker. At this time, an abnormal operation signal is output to identify the situation so that the management personnel can be informed of the situation in time, so that the safety hazard can be eliminated in time to reduce the possibility of safety accidents during the construction process.

[0032] Step S1052: If the operator's working posture is not in the dangerous posture set, a normal working signal is output.

[0033] When the personnel's working posture is not in the dangerous posture set, it means that there is no safety hazard in the staff's working process. At this time, a normal working signal can be output to identify the situation.

[0034] The steps of performing posture simulation based on the personnel's own parameters and the reading positions of each component to determine the personnel's working posture include: Step S200: Perform posture simulation based on the person's own parameters and the reading positions of each component to determine the person's possible posture.

[0035] The possible posture of the personnel is a posture that can be obtained by simulating the limbs and head of the personnel and can represent the posture of the personnel.

[0036] Step S201: Counting possible postures of a person to determine the possible number of postures.

[0037] The possible number of postures is the total number of possible postures of the person determined.

[0038] Step S202: Determine whether the possible number of postures is one.

[0039] The purpose of the judgment is to find out whether the actual posture of the person can be determined more accurately.

[0040] Step S2021: If the number of possible postures is one, the possible posture of the person is determined as the working posture of the person.

[0041] When the possible number of postures is one, it means that the user has only one posture, and it can be determined as the personnel working posture.

[0042] Step S2022: If the possible number of postures is not one, the previously determined working posture of the personnel is defined as the preceding working posture.

[0043] When the possible number of postures is not one, it means that there are multiple postures that may be the actual postures of the staff, so the previous operation posture is defined to facilitate the analysis of the current actual posture situation of the personnel.

[0044] Step S203: Determine possible parameters of the change according to the previous operation posture and the possible posture of the personnel.

[0045] The possible change parameter is the possibility parameter of the worker changing from the previous working posture to the possible posture of the personnel. The larger the value is, the higher the possibility of the worker changing from the previous working posture to the possible posture of the personnel. The determination of the possible change parameter can refer to steps S300-S303.

[0046] Step S204: determining the possible change parameter with the largest value according to a preset sorting rule, and determining the possible posture of the person corresponding to the possible change parameter as the working posture of the person.

[0047] The sorting rule is a method set by the staff to sort the size of the values, such as the bubble method. The sorting rule can be used to determine the possible parameter with the largest numerical change, that is, the corresponding possible posture of the person at this time is most likely to be the posture of the staff in actual situation, so it can be determined as the working posture of the person.

[0048] The steps of determining possible parameters of the change based on the previous operation posture and the possible posture of the personnel include: Step S300: establishing a history interval with a width of a preset history length on a preset time axis with the current time point as the rear end point.

[0049] The time axis is a coordinate axis formed by the combination of various time points. The coordinate axis points from the time points that have passed to the time points that have not yet arrived, where the time points that have passed are on the left side of the coordinate axis, and the left side is defined as the front; the historical duration is the fixed duration set by the staff, that is, the duration between the construction of the work project and the current time point. By constructing the historical interval, it is convenient to obtain data after the construction of the project.

[0050] Step S301: Determine the task execution period according to the personnel performing the task in the historical interval, and define the time point when the personnel's working posture is consistent with the current preceding working posture in a single task execution period as a similar time point, and define the personnel's working posture determined after the similar time point as a similar subsequent posture.

[0051] The task execution period is the working period when the same task as the current task is executed in the historical interval. Similar time points are defined to distinguish the time points of the same posture of other staff members as the current staff member, which is convenient for subsequent analysis. At the same time, similar subsequent postures are defined to identify the subsequent postures of personnel with the same action, which is convenient for subsequent analysis.

[0052] Step S302: Counting is performed according to each identical similar post-sequence posture to determine the number of monomer post-sequences, and summing up all monomer post-sequence numbers to determine the overall post-sequence number.

[0053] The number of monomer post-orders is the number of times the same similar post-order posture appears, and the overall post-order number is the sum of all monomer post-order numbers.

[0054] Step S303: Calculate the post-sequence ratio according to the number of individual post-sequences and the number of overall post-sequences, and calculate the possible parameters of the possible posture changes of the person consistent with the similar post-sequence posture according to the post-sequence ratio.

[0055] The post-sequence ratio is the ratio of the number of times a similar post-sequence posture appears to the number of times all similar post-sequence postures appear, and is determined by dividing the number of single post-sequences by the number of overall post-sequences. The possible change parameters can be obtained by multiplying the post-sequence ratio by the preset fixed parameters, so as to effectively predict and analyze the changes in posture.

[0056] After the possible parameters of change are determined, the construction safety monitoring method also includes: Step S400: Determine whether there are at least two possible postures of a person with the same and maximum possible change parameter values.

[0057] The purpose of the judgment is to find out whether there are multiple possible personnel postures that meet the requirements, so as to determine the unique personnel working posture.

[0058] Step S4001: If there are not at least two possible personnel postures with the same value of possible variation parameters and the largest possible personnel posture, the possible personnel posture corresponding to the largest possible variation parameter is determined as the personnel working posture.

[0059] When there are not at least two possible personnel postures with the same and largest possible change parameter values, it means that there is only one possible personnel posture that meets the requirements, and it can be determined as the personnel working posture.

[0060] Step S4002: If there are at least two possible human postures with the same possible change parameter value and the largest possible human posture, the possible human posture corresponding to the largest possible change parameter is defined as an alternative possible posture.

[0061] When there are at least two possible personnel postures with the same and largest possible change parameter values, it means that there are multiple possible personnel postures that meet the requirements. At this time, they are defined as candidate possible postures for subsequent analysis.

[0062] Step S401: defining the previously determined working posture of a person as an initial working posture, and analyzing the initial working posture and the previous working posture in a historical interval to determine the predicted selection rate of each candidate possible posture.

[0063] The initial working posture is defined to identify the posture of the worker between the previous working postures, so as to facilitate subsequent analysis; the predicted selection rate is the possibility value of the alternative possible postures obtained according to the changes in the initial working posture and the previous working posture. The method for determining the predicted selection rate can refer to the method of steps S300-S303, that is, the specific changes of the personnel with the same posture changes are used for analysis.

[0064] Step S402: Determine the predicted selection rate with the largest value according to the sorting rule, and determine the candidate possible posture corresponding to the predicted selection rate as the personnel working posture.

[0065] The predicted selection rate with the largest value can be determined through the sorting rules, that is, the corresponding alternative possible posture at this time has the highest possibility as the posture of the person in the actual situation, so it can be determined as the working posture of the person.

[0066] If the personnel's working posture is not in the dangerous posture set, the construction safety monitoring method also includes: Step S500: Determine the same operation period in the historical interval according to the component monitoring personnel and the personnel performing tasks.

[0067] The same operating period is the operating period when the current component monitoring personnel performs the same task as the current personnel performs the task.

[0068] Step S501: Combining the working postures of personnel in the same working period to construct a personnel posture set.

[0069] The personnel posture set is the set of all personnel working postures that appear in the same working period.

[0070] Step S502: Determine whether the current working posture of the personnel is in the personnel posture set.

[0071] The purpose of the judgment is to find out whether the posture of the current operating personnel is consistent with the historical working posture of the personnel, so as to determine whether there is a situation where personnel are taking shifts, where the shift taking situation is when personnel with different heights and images wear work clothes and safety helmets that do not belong to them.

[0072] Step S5021: If the current working posture of the personnel is in the personnel posture set, a normal working signal is output.

[0073] When the current working posture of the personnel is in the personnel posture set, it means that the posture of the personnel is relatively correct. At this time, a normal working signal can be output to identify the situation.

[0074] Step S5022: If the current working posture of the personnel is not in the personnel posture set, a special marking signal is output, and a detection interval of a preset detection duration is constructed on the time axis with the current time point as the front end point.

[0075] When the current working posture of the personnel is not in the personnel posture set, it means that the personnel has made an abnormal action. At this time, a special marking signal is output to identify the situation for subsequent analysis. The detection time is a fixed time set by the staff. By constructing a detection interval, it is convenient to obtain and analyze the data within the detection time.

[0076] Step S503: Determine whether a special mark signal is output in the detection interval.

[0077] The purpose of the judgment is to find out whether abnormal actions continue to occur in the detection interval.

[0078] Step S5031: If no special mark signal is output in the detection interval, a normal operation signal is output.

[0079] When no special mark signal is output in the detection interval, it means that there is no abnormal action in the detection interval, that is, the working posture of the personnel who was not in the personnel posture set before was an accidental operation of the staff, and no additional attention is required. At this time, a normal operation signal can be output.

[0080] Step S5032: If a special mark signal is output in the detection interval, a personnel replacement signal is output.

[0081] When a special mark signal is output in the detection interval, it means that actions that are inconsistent with the person's habits have occurred multiple times in a short period of time, that is, there is a high possibility that a person will be replaced on shift. Therefore, a personnel replacement signal is output so that the management personnel can be informed of the situation in time to facilitate subsequent management.

[0082] The step of determining the detection duration is also included, and the step includes: Step S600: Counting the personnel replacement signal corresponding to the current component monitoring personnel in the historical interval to determine the number of replacement times.

[0083] The number of substitutions is the total number of times the currently monitored person has replaced a shift in history, and can be determined by counting the personnel substitution signals corresponding to the person in the historical interval one by one.

[0084] Step S601: Calculate and determine the extension duration according to the number of replacements and the preset severe duration.

[0085] The serious duration is the fixed duration set by the staff, and the extended duration is the extended duration for different personnel, which is determined by multiplying the number of replacements by the serious duration.

[0086] Step S602: performing a sum calculation based on the extended time and the preset reference time to determine the detection time.

[0087] The benchmark duration is a fixed duration set by the staff. The detection duration can be determined by adding the extended duration to the benchmark duration. At this time, it can be ensured that the more times a person takes shift replacements, the longer the corresponding detection time, that is, the more stringent the detection of shift replacements.

[0088] After the component reading position is determined, the construction safety monitoring method further includes: Step S700: Determine the work range area corresponding to the task performed by the personnel according to the preset area matching relationship.

[0089] The operating scope area is the area where the staff needs to be when performing the current personnel task. Different personnel perform tasks corresponding to different operating scope areas. The area matching relationship between the two can be determined and entered in advance by the staff.

[0090] Step S701: Determine whether all component reading positions are within the operating range.

[0091] The purpose of the judgment is to find out whether the staff has left the work area without permission.

[0092] Step S7011: If the component reading positions are all within the operating range, posture analysis is performed based on the component reading positions.

[0093] When the component reading positions are all within the operating range, it means that the staff to be monitored are working normally, and the posture analysis can be carried out normally.

[0094] Step S7012: If the component reading positions are not all within the operating range, a departure signal is output.

[0095] When the component reading positions are not all within the working range, it means that the staff has left the working range without permission. At this time, a departure signal is output to mark the situation so that the management personnel can be informed of the situation in time and facilitate subsequent processing of the situation.
