Description

Technical Field

[0001] This application relates to the field of construction safety monitoring, and in particular, to a method and system for building construction safety monitoring. Background Art

[0002] During the building construction process, due to the complex construction environment, diverse construction techniques, and the involvement of numerous personnel and large-scale mechanical equipment, there are many potential safety hazards. Therefore, it is necessary to effectively monitor the safety during the building construction process. Among them, the safety monitoring of the staff is of utmost importance.

[0003] Currently, the safety monitoring of the staff often relies on regular manual inspections. That is, when the monitoring personnel observe problems such as non-standard operations of the staff, they can detect abnormal situations. However, since the inspectors need to continuously conduct inspections and cannot always observe a single location, it is easy for abnormal operations to exist for a certain period of time before being discovered, resulting in untimely monitoring and safety accidents, and there is still room for improvement.

[0069] Figure 2 is a module flowchart of a building construction safety monitoring method. DETAILED DESCRIPTION OF THE EMBODIMENTS

[0070] In order to make the purpose, technical solution and advantages of the present application clearer, the following Figure 1 - Figure 2 and embodiments are used to further elaborate on the present application. It 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.

[0071] The following further describes the embodiments of the present application in detail with reference to the accompanying drawings of the specification.

[0072] The embodiments of the present application disclose a building construction safety monitoring method. Referring to Figure 1 , the method flow of the building construction safety monitoring method includes the following steps:

[0073] Step S100: Obtain the component reading positions and component numbers of the positioning components set on the limbs and head of the staff.

[0074] The positioning component is a module component that can transmit real-time position information in space, such as a position sensor. By setting the positioning components on the limbs and head of the staff, the approximate position of the staff can be determined, facilitating subsequent analysis. Among them, the positioning components 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.

[0075] Step S101: Determine the component monitoring personnel and the personnel's own parameters corresponding to the component number according to the preset personnel matching relationship.

[0076] The component monitoring personnel are the personnel currently conducting the monitoring. Different personnel have different corresponding component numbers, so the personnel can be determined through the component number. The personnel's own parameters are the parameter values of the personnel corresponding to the component number. These parameters include height, body shape, etc. That is, an effective human model of the staff can be constructed through the personnel's own parameters. The personnel matching relationship among the three is determined by the management personnel obtaining and inputting the information of each staff member in advance.

[0077] Step S102: Conduct posture simulation according to the personnel's own parameters and the reading positions of each component to determine the personnel's working posture.

[0078] The personnel's working posture is the current posture of the staff. The positions of the next positioning components of different personnel are different, and the corresponding postures are also different. Therefore, the personnel's posture can be determined by inputting the component reading position into the corresponding human model. The method of determining the personnel's posture through the positions of the limbs and head can refer to VR technology, which is a conventional technical means for those skilled in the art and will not be elaborated here.

[0079] Step S103: Determine the task executed by the personnel in the preset task database according to the current time point and the component monitoring personnel.

[0080] The task executed by the personnel is the task currently being executed by the component monitoring personnel, including building steel frames, etc. The task database stores the task information of each staff member who is currently working.

[0081] Step S104: Determine the set of dangerous postures corresponding to the task executed by the personnel according to the preset posture matching relationship.

[0082] The set of dangerous postures is a set composed of postures that can be recognized as dangerous when the staff has inaccurate postures when performing the current task executed by the personnel. Since different personnel need to perform different operations when executing tasks, the corresponding sets of dangerous postures are also different. The posture matching relationship between the two is determined by the staff through multiple tests in advance and will not be elaborated here.

[0083] Step S105: Determine whether the working posture of the personnel is in the set of dangerous postures.

[0084] The purpose of the determination is to effectively monitor the current posture of the staff member to determine whether there are potential safety hazards.

[0085] Step S1051: If the working posture of the personnel is in the set of dangerous postures, an abnormal operation signal is output.

[0086] When the working posture of the personnel is in the set of dangerous postures, it indicates that there are potential safety hazards in the current posture of the staff member. At this time, an abnormal operation signal is output to identify this situation, so that the management personnel can know this situation in a timely manner, and thus can eliminate the potential safety hazards in a timely manner to reduce the possibility of safety accidents occurring during the construction process.

[0087] Step S1052: If the working posture of the personnel is not in the set of dangerous postures, a normal operation signal is output.

[0088] When the working posture of the personnel is not in the set of dangerous postures, it indicates that there are no potential safety hazards during the operation of the staff member. At this time, a normal operation signal is output to identify this situation.

[0089] The steps for posture simulation based on the personnel's own parameters and the reading positions of each component to determine the working posture of the personnel include:

[0090] Step S200: Perform posture simulation based on the personnel's own parameters and the reading positions of each component to determine the possible postures of the personnel.

[0091] The possible postures of the personnel are the postures that can represent the posture situation of the staff member obtained after simulating the limbs and head of the personnel.

[0092] Step S201: Count based on the possible postures of the personnel to determine the possible number of postures.

[0093] The possible number of postures is the total number of the determined possible postures of the personnel.

[0094] Step S202: Determine whether the possible number of postures is one.

[0095] The purpose of the determination is to know whether the actual posture of the personnel can be determined more accurately.

[0096] Step S2021: If the possible number of postures is one, determine the possible posture of the personnel as the working posture of the personnel.

[0097] When the possible number of postures is one, it means that the user has only one posture. At this time, it can be determined as the working posture of the personnel.

[0098] Step S2022: If the number of possible postures is not one, define the previously determined personnel operation posture as the previous operation posture.

[0099] When the number of possible postures is not one, it indicates that there are multiple postures that may be the actual posture of the staff. Therefore, defining the previous operation posture facilitates the analysis of the current actual posture situation of the personnel.

[0100] Step S203: Determine the change possibility parameter based on the previous operation posture and the possible postures of the personnel.

[0101] The change possibility parameter is the possibility parameter for the staff to change from the previous operation posture to the possible posture of the personnel. The larger this value, the higher the possibility for the staff to change from the previous operation posture to the possible posture of the personnel. The determination of the change possibility parameter can refer to Step S300 - Step S303.

[0102] Step S204: Determine the change possibility parameter with the largest value according to the preset sorting rule, and determine the possible posture of the personnel corresponding to this change possibility parameter as the personnel operation posture.

[0103] The sorting rule is a method set by the staff to sort the magnitudes of values, such as the bubble sort method. Through the sorting rule, the change possibility parameter with the largest value can be determined, that is, the corresponding possible posture of the personnel at this time has the highest possibility of being the actual posture of the staff. Therefore, it can be determined as the personnel operation posture.

[0104] The steps of determining the change possibility parameter based on the previous operation posture and the possible postures of the personnel include:

[0105] Step S300: Establish a historical interval with a width of the preset historical duration on the preset time axis with the current time point as the rear endpoint.

[0106] The time axis is an axis formed by combining each time point. This axis points from the time points that have passed to the time points that have not yet been reached. Among them, the time points that have passed are on the left side of the axis, and the left side is defined as the front; the historical duration is a fixed duration set by the staff, that is, the duration between the start of the construction of this work item and the current time point. By constructing the historical interval, it is convenient to obtain the data after the construction of this project.

[0107] Step S301: Determine the task execution period according to the tasks performed by the personnel in the historical interval, and define the time points when the personnel operation posture is consistent with the current previous operation posture in a single task execution period as similar time points, and define the personnel operation posture determined after the similar time points as the similar subsequent posture.

[0108] The task execution period is the operation period when performing tasks of the same type as the current task in the historical interval. Similar time points are defined to distinguish the time points with the same posture of the remaining staff from that of the current staff, facilitating subsequent analysis. At the same time, similar subsequent postures are defined to identify the subsequent postures of personnel with the same actions, facilitating subsequent analysis.

[0109] Step S302: Count according to each identical similar subsequent posture to determine the single subsequent quantity, and perform a summation calculation based on all the single subsequent quantities to determine the overall subsequent quantity.

[0110] The single subsequent quantity is the number of times a same similar subsequent posture appears, and the overall subsequent quantity is the sum of all single subsequent quantities.

[0111] Step S303: Calculate based on the single subsequent quantity and the overall subsequent quantity to determine the subsequent proportion, and calculate based on the subsequent proportion to determine the possible change parameters of the possible postures of the personnel consistent with the similar subsequent posture.

[0112] The subsequent proportion is the ratio of the number of times a similar subsequent posture appears to the number of times all similar subsequent postures appear, which is determined by dividing the single subsequent quantity by the overall subsequent quantity. The possible change parameters can be obtained by multiplying the subsequent proportion by a preset fixed parameter to effectively predict and analyze the change situation of the posture.

[0113] After determining the possible change parameters, the building construction safety monitoring method further includes:

[0114] Step S400: Determine whether there are at least two possible postures of personnel with the same and maximum possible change parameter values.

[0115] The purpose of the determination is to find out whether there are multiple possible postures of personnel that meet the requirements, so as to determine the unique working posture of the personnel.

[0116] Step S4001: If there are no at least two possible postures of personnel with the same and maximum possible change parameter values, then determine the possible posture of the personnel corresponding to the maximum possible change parameter as the working posture of the personnel.

[0117] When there are no at least two possible postures of personnel with the same and maximum possible change parameter values, it means that there is only one possible posture of the personnel that meets the requirements. At this time, it can be determined as the working posture of the personnel.

[0118] Step S4002: If there are at least two possible postures of personnel with the same and maximum possible change parameter values, then define the possible posture of the personnel corresponding to the maximum possible change parameter as the alternative possible posture.

[0119] When there are at least two possible postures of personnel with the same and maximum values of the variable possible parameters, it indicates that there are multiple possible postures of personnel that meet the requirements. At this time, they are defined as alternative possible postures for subsequent analysis.

[0120] Step S401: Define the previous determined personnel operation posture of the previous operation posture as the initial operation posture, and analyze in the historical interval according to the initial operation posture and the previous operation posture to determine the prediction selection rate of each alternative possible posture.

[0121] Defining the initial operation posture to identify the posture of this staff member between the previous operation postures is convenient for subsequent analysis; the prediction selection rate is the likelihood degree value of the alternative possible posture obtained according to the changes of the initial operation posture and the previous operation posture. The determination method of this prediction selection rate can refer to the method of steps S300 - S303, that is, analyze using the specific changes of personnel with the same posture changes.

[0122] Step S402: Determine the prediction selection rate with the maximum value according to the sorting rule, and determine the alternative possible posture corresponding to this prediction selection rate as the personnel operation posture.

[0123] Through the sorting rule, the prediction selection rate with the maximum value can be determined, that is, at this time, the corresponding alternative possible posture has the highest possibility as the posture of this personnel in the actual situation. Therefore, it can be determined as the personnel operation posture.

[0124] If the personnel operation posture is not in the dangerous posture set, the building construction safety monitoring method further includes:

[0125] Step S500: Determine the same operation period according to the component monitoring personnel and the personnel performing tasks in the historical interval.

[0126] The same operation period is the operation period when the current component monitoring personnel perform the tasks of the current personnel performing tasks.

[0127] Step S501: Combine the personnel operation postures within the same operation period to construct a personnel posture set.

[0128] The personnel posture set is the set composed of all the personnel operation postures that this personnel has shown within the same operation period.

[0129] Step S502: Determine whether the current personnel operation posture is in the personnel posture set.

[0130] The purpose of the determination is to know whether the posture of the current operating personnel conforms to the historical operation postures of this personnel to judge whether there is a situation of personnel substitution. Among them, the substitution situation is when personnel with different heights and images wear work clothes and safety helmets that do not belong to themselves.

[0131] Step S5021: If the current personnel operation posture is within the personnel posture set, output a normal operation signal.

[0132] When the current personnel operation posture is within the personnel posture set, it indicates that the staff's posture is relatively correct. At this time, output a normal operation signal to identify this situation.

[0133] Step S5022: If the current personnel operation posture is not within the personnel posture set, output a special mark signal, and construct a detection interval with a preset detection duration on the time axis with the current time point as the front end point.

[0134] When the current personnel operation posture is not within the personnel posture set, it indicates that the staff has abnormal actions. At this time, output a special mark signal to identify this situation for subsequent analysis; the detection duration is a fixed value set by the staff, and constructing the detection interval facilitates the acquisition and analysis of data within the detection duration.

[0135] Step S503: Determine whether a special mark signal is output within the detection interval.

[0136] The purpose of the determination is to find out whether there are still abnormal actions within the detection interval.

[0137] Step S5031: If no special mark signal is output within the detection interval, output a normal operation signal.

[0138] When no special mark signal is output within the detection interval, it indicates that there are no abnormal actions within the detection interval, that is, the personnel operation posture that was not within the personnel posture set before was an accidental operation by the staff and does not require extra attention. At this time, output a normal operation signal.

[0139] Step S5032: If a special mark signal is output within the detection interval, output a personnel replacement signal.

[0140] When a special mark signal is output within the detection interval, it indicates that actions that do not conform to the habits of this personnel occur multiple times in a short period, that is, there is a high possibility of personnel substitution. Therefore, output a personnel replacement signal so that the management personnel can learn of this situation in a timely manner for subsequent management.

[0141] It also includes a step for determining the detection duration, and this step includes:

[0142] Step S600: Count according to the personnel replacement signals corresponding to the current component monitoring personnel in the historical interval to determine the number of replacements.

[0143] Instead of the total number of times of shift substitution for the person being monitored currently in historical situations, it can be determined by counting one by one the person substitution signals corresponding to this person in the historical period.

[0144] Step S601: Calculate according to the substitution times and a preset severe duration to determine an extended duration.

[0145] The severe duration is a fixed value duration set by the staff, and the extended duration is the duration extended for different persons, which is determined by multiplying the substitution times by the severe duration.

[0146] Step S602: Perform a summation calculation according to the extended duration and a preset reference duration to determine a detection duration.

[0147] The reference duration is a fixed value duration set by the staff. The detection duration can be determined by adding the extended duration and the reference duration. At this time, it can be ensured that the longer the detection duration corresponds to the person with more substitution times, that is, the more strict the detection of the shift substitution situation is.

[0148] After the component reading position is determined, the building construction safety monitoring method further includes:

[0149] Step S700: Determine the operation range area corresponding to the person's task execution according to a preset area matching relationship.

[0150] The operation range area is the area range where the staff needs to be when performing the current person's task execution. Different person task executions correspond to different operation range areas, and the area matching relationship between the two can be determined and input by the staff in advance.

[0151] Step S701: Determine whether all the component reading positions are within the operation range area.

[0152] The purpose of the determination is to know whether the staff has left the work area without permission.

[0153] Step S7011: If all the component reading positions are within the operation range area, perform pose analysis according to the component reading positions.

[0154] When all the component reading positions are within the operation range area, it means that the staff to be monitored is working normally, and at this time, the pose situation can be analyzed normally.

[0155] Step S7012: If not all the component reading positions are within the operation range area, output a signal of unauthorized departure.

[0156] When the component reading positions are not all within the operation range area, it indicates that the staff has left the working range without permission. At this time, an unauthorized departure signal is output to identify this situation, so that the management personnel can know this situation in time and facilitate subsequent handling of this situation.
