Description

Technical Field

[0001] The present application relates to the technical field of hoisting construction, and in particular to a BIM-based steel structure factory building hoisting construction safety monitoring method, system and terminal. Background Art

[0002] With the acceleration of my country's industrialization and urbanization, the types and number of steel structure workshops are increasing. According to statistics, steel structure buildings account for nearly 5% of the entire construction industry in my country, among which the largest type of steel structure building is steel structure workshops.

[0003] In recent years, facing the increasingly competitive and declining profit in the construction market, many construction companies have excessively pursued economic benefits, put the basic principles of "quality-oriented" and "safety first" behind their minds, lacked attention to the construction methods and construction process of steel structure workshops, and insufficient consideration of the impact of various factors on the structure during the construction process. As a result, after the construction of the steel structure workshop is completed, its stress and deformation state are greatly different from the design, which greatly increases the unsafe hidden dangers of the structure. Therefore, how to quickly complete a steel structure workshop that meets the standards and requirements while ensuring construction safety has become a research topic that steel structure workshop construction companies and managers pay close attention to.

[0004] At present, when hoisting construction is carried out on steel structure workshops, due to the limitations of operator experience and non-standard operation of construction workers, the hoisting of the same component may require multiple times to complete, and hoisting errors are prone to occur, thus affecting the progress of the hoisting construction. Summary of the invention

[0005] In order to improve the progress of hoisting construction, the present application provides a BIM-based steel structure plant hoisting construction safety monitoring method, system and terminal.

[0006] In the first aspect, the present application provides a BIM-based steel structure factory building hoisting construction safety monitoring method, which adopts the following technical solutions: A BIM-based steel structure plant hoisting construction safety monitoring method, comprising: Construct the BIM model of the steel structure workshop; According to the current hoisting node, selecting a BIM model segment corresponding to the current hoisting node from the BIM model; Extracting standard lifting parameters according to the BIM model segment; During the hoisting construction, the actual hoisting parameters of the current hoisting node are obtained in real time; Determining whether the actual lifting parameters match the standard lifting parameters; If not, output adjustment prompt information.

[0007] By adopting the above technical solution, after the BIM model of the steel structure factory is constructed, the corresponding BIM model end can be selected from the BIM model according to the current lifting node, and then the lifting standard parameters can be extracted; then during the lifting construction, the actual lifting parameters of the current lifting node are obtained, and the actual lifting parameters are compared with the lifting standard parameters. If the two match, it means that the lifting construction is correct; if the two do not match, adjustment prompt information can be output to enable the construction personnel to make adjustments according to the lifting standard parameters; since the construction personnel can make adjustments according to the lifting standard parameters during the lifting construction, the progress of the lifting construction is improved.

[0008] Optionally, the standard lifting parameters include the component information required for the current lifting node and the standard lifting operation record; the actual lifting parameters include the actual component information of the current lifting node and the actual lifting operation record; The step of judging whether the actual lifting parameters match the standard lifting parameters comprises: Determine whether the actual component information of the current hoisting node matches the component information required for the current hoisting node; If yes, continue to determine whether the standard hoisting operation record matches the actual hoisting operation record; If not, output adjustment prompt information.

[0009] By adopting the above technical solution, it is possible to confirm whether the actual components of the current lifting node are consistent with the required components, thereby avoiding rework and delays caused by incorrect or misused components, and ensuring that the correct components are used at each lifting node. By comparing the standard lifting operation records with the actual operation records, it can be ensured that the lifting process is strictly carried out in accordance with the established process, reducing human errors and negligence, thereby improving construction accuracy.

[0010] Optionally, the hoisting construction safety monitoring method further includes: Before hoisting, collect image information of construction workers who are about to enter the pre-set hoisting area; Based on the image information, determining whether the construction personnel are wearing safety protection equipment; If not, output the entry denial information; If yes, then receive the construction worker's sign-in information; Based on the sign-in information, retrieve the personnel attribute information pre-associated with the sign-in information; Based on the personnel attribute information, corresponding security inquiry information is output.

[0011] By adopting the above technical solution, the safety of construction personnel entering the hoisting area and the safety of hoisting construction can be improved.

[0012] Optionally, after retrieving the personnel attribute information pre-associated with the sign-in information, the method further includes: Determining whether the personnel attribute information corresponding to the construction personnel is unique; If yes, directly output the corresponding security inquiry information; If not, obtain the construction status corresponding to the current construction personnel; Based on the construction status, determining current personnel attribute information; Based on the current personnel attribute information, corresponding security inquiry information is output.

[0013] By adopting the above technical solution, by judging whether the personnel attribute information of the construction personnel is unique, it can be ensured that each construction personnel is authenticated and authorized, thereby preventing unauthorized personnel from entering the construction site and reducing safety risks; for construction personnel who pass the uniqueness verification, the corresponding safety inquiry information is directly output, and personalized safety reminders can be given according to their personal characteristics and responsibilities to improve safety awareness.

[0014] Optionally, the specific steps of obtaining the construction status corresponding to the current construction personnel include: Identify construction identification information on the safety protection equipment in the image information; According to the construction identification information, the associated construction status is searched from a preset construction identification library, which is the current construction status.

[0015] By adopting the above technical solution, through image recognition technology, the construction identification information on the safety protection equipment can be quickly captured and identified, so as to provide instant feedback on the current construction status.

[0016] Optionally, the hoisting construction safety monitoring method further includes: After the sign-in time is over, the construction type of the personnel attribute information corresponding to the construction personnel entering the hoisting area is counted; Determine whether the construction types are complete; If not, continue to determine whether the missing construction type is a necessary type; If so, a temporary operation instruction is sent to the construction personnel corresponding to the non-essential type who lacks the personnel attribute information corresponding to the construction type.

[0017] By adopting the above technical solution, the sign-in time ends, indicating that the construction personnel have finished entering the site; at this time, the types of personnel attribute information corresponding to the construction personnel entering the lifting area can be counted to determine whether the types are complete. If not, it is possible to continue to determine whether the missing types are necessary types. If so, a temporary operation instruction can be sent to the construction personnel corresponding to the non-essential types of the construction status corresponding to the missing types; thereby, temporary conversion of the construction status can be achieved, thereby avoiding delays in the construction period and further improving the lifting efficiency.

[0018] Optionally, after outputting the corresponding security inquiry information, the following steps are included: Obtain feedback from construction personnel; According to the feedback information, judging whether the hoisting can be carried out normally; If not, output the hoisting adjustment information.

[0019] By adopting the above technical solutions, according to the feedback from the construction workers, the management can flexibly adjust the lifting plan or operation method to adapt to the actual situation on site and ensure the safe progress of the lifting operation.

[0020] Optionally, after outputting the access denial information, the output includes: Count the number of times the entry denial information is output within the sign-in time; Determining whether the output times exceed a preset times threshold; If so, output the correction information.

[0021] By adopting the above technical solution, if the number of times the entry refusal information is output exceeds the number threshold, it means that the safety protection information of the entire construction team is relatively weak, and therefore rectification information needs to be output for rectification.

[0022] In the second aspect, the present application provides a BIM-based steel structure plant hoisting construction safety monitoring system, which adopts the following technical solutions: A BIM-based steel structure plant hoisting construction safety monitoring system, including: Model building module, used to build the BIM model of the steel structure workshop; A parameter extraction module is used to select a BIM model segment corresponding to the current lifting node from the BIM model according to the current lifting node, and extract the lifting standard parameters from the BIM model segment; A parameter acquisition module is used to obtain the actual lifting parameters of the current lifting node in real time during the lifting construction; A judgment module, used to judge whether the actual lifting parameters match the standard lifting parameters; The information output module is used to output adjustment prompt information.

[0023] By adopting the above technical solution, after the BIM model of the steel structure factory is constructed, the corresponding BIM model end can be selected from the BIM model according to the current lifting node, and then the lifting standard parameters can be extracted; then during the lifting construction, the actual lifting parameters of the current lifting node are obtained, and the actual lifting parameters are compared with the lifting standard parameters. If the two match, it means that the lifting construction is correct; if the two do not match, adjustment prompt information can be output to enable the construction personnel to make adjustments according to the lifting standard parameters; since the construction personnel can make adjustments according to the lifting standard parameters during the lifting construction, the progress of the lifting construction is improved.

[0024] In a third aspect, the present application provides a terminal, which adopts the following technical solution: A terminal, comprising: A memory storing a BIM-based steel structure plant hoisting construction safety monitoring program; The processor is used to execute the program stored in the memory to implement the steps of the above-mentioned BIM-based steel structure factory building hoisting construction safety monitoring method.

[0025] In summary, the present application has at least the following beneficial effects: 1. The purpose of constructing the BIM model of the steel structure workshop, extracting the standard parameters for hoisting, and comparing the actual parameters for hoisting with the standard parameters for hoisting is that if the two match, the hoisting construction is correct; if the two do not match, adjustment prompt information can be output to enable construction personnel to make adjustments according to the standard parameters for hoisting; since construction personnel can make adjustments according to the standard parameters for hoisting during hoisting construction, the progress of hoisting construction is improved.

DETAILED DESCRIPTION

[0030] To make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the following will be combined with the appended drawings of the embodiments of the present invention. Figure 1 -Attached Figure 6 , the technical solutions in the embodiments of the present invention are clearly and completely described. Obviously, the described embodiments are part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0031] The first embodiment of the present application discloses a BIM-based steel structure factory building hoisting construction safety monitoring method. Figure 1 As an implementation of the hoisting construction safety monitoring method, the hoisting construction safety monitoring method may include S110-S170: S110, constructing the BIM model of the steel structure workshop; S120, selecting a BIM model segment corresponding to the current hoisting node from the BIM model according to the current hoisting node; S130, extracting hoisting standard parameters according to the BIM model segment; S140, during the hoisting construction, obtaining the actual hoisting parameters of the current hoisting node in real time; S150, determining whether the actual lifting parameters match the lifting standard parameters; S160, if not, outputting adjustment prompt information; S170: If yes, then no response.

[0032] Specifically, the BIM model of the steel structure plant is established through BIM software, and the BIM model is the model after the steel structure plant is built. When the current hoisting node is confirmed, the BIM model segment corresponding to the current hoisting node will be selected from the BIM model. It can be simply understood that the BIM model is split according to the construction steps, and then the BIM model segment of the hoisting step is extracted separately, and then according to the current hoisting node, the BIM model segment corresponding to the hoisting node is further extracted from the BIM model segment of the hoisting step, and then the associated parameters are retrieved, which are the hoisting standard parameters corresponding to this hoisting node.

[0033] The standard lifting parameters include the component information required for the current lifting node, standard lifting operation records, etc.; the required component information includes the component name, quantity, and size; the standard lifting operation records include the component installation position, the model of the applicable lifting tool for the component, the movement trajectory of the component during lifting, etc.

[0034] The actual lifting parameters include the actual component information of the current lifting node, the actual lifting operation records, etc.

[0035] To determine whether the standard parameters of lifting match the actual parameters of lifting, you can first determine whether the actual component information of the current lifting node matches the required component information of the current lifting node; that is, whether the actual component name, quantity, and size are the same as the corresponding required component name, quantity, and size; if so, continue to determine whether the standard operation record of lifting matches the actual operation record of lifting; that is, whether the component installation position, the model of the applicable lifting tool for the component, and the movement trajectory of the component during lifting are the same as the corresponding required component installation position, the applicable lifting tool model, and the lifting movement trajectory. If not, output the adjustment prompt information. It should be noted that during actual lifting, the hoisting machine and the component placement position should be the same as the pre-built hoisting machine and component placement position in the BIM model.

[0036] Reference Figure 2 As another implementation of the hoisting construction safety monitoring method, the hoisting construction safety monitoring method further includes S210-S260: S210, before hoisting, collecting image information of construction workers who are about to enter a preset hoisting area; S220, judging whether the construction workers are wearing safety protection equipment based on the image information; S230, if yes, receiving the construction worker's sign-in information; S240, based on the sign-in information, retrieve the personnel attribute information pre-associated with the sign-in information; S250, outputting corresponding security inquiry information based on the personnel attribute information; S260: If not, output the entry denial information.

[0037] Specifically, the hoisting area is set in advance according to the construction scope, the entrance and exit of the hoisting area can be on the same side, and gates, image acquisition equipment, card readers, and broadcasters are set at the entrance and exit. When construction personnel need to enter the hoisting area, the image acquisition equipment first collects the image information of the construction personnel, and uses the image recognition algorithm to identify whether the construction personnel are wearing safety protection equipment (including safety helmets, safety clothing, etc.). If not, the broadcaster can broadcast the information of denying entry; the information of denying entry can be "no entry without wearing a safety helmet", etc.

[0038] If the construction worker wears safety protection equipment, the construction worker places the pre-sent card on the card reader, and the card reader reads the information and identifies the construction worker's sign-in information; after successful reading, the construction worker signs in successfully. In other implementations, the card reader can also use a fingerprint identifier.

[0039] The construction worker's name, sign-in information, and personnel attribute information are associated and set. After the sign-in is successful, the associated personnel attribute information can be retrieved according to the sign-in information; the personnel attribute information includes ordinary hoisting workers, safety officers / supervisors, operators / drivers, etc., which are used to characterize different construction types of construction workers.

[0040] After the construction worker successfully signs in, the announcer can output corresponding safety inquiry information based on the personnel attribute information corresponding to the construction worker; for example, if the personnel attribute information corresponding to the construction worker is an operator, the corresponding safety inquiry information may be "whether the lifting equipment is maintained"; if the personnel attribute information corresponding to the construction worker is an ordinary lifting worker, the corresponding safety inquiry information may be "whether the construction specifications are understood"; if the personnel attribute information corresponding to the construction worker is a safety officer, the corresponding safety inquiry information may be "whether the safety supervision specifications are understood".

[0041] Furthermore, when the sign-in time is over, the number of times the entry denial information is output can be counted and the number of outputs can be judged. If the number of outputs exceeds a preset number threshold, rectification information can be output.

[0042] Further, refer to Figure 3 , after S240 and before S250, S310-S350 can be executed: S310, determining whether the personnel attribute information corresponding to the construction personnel is unique; S320, if yes, directly output corresponding security inquiry information; S330, if not, obtaining the construction status corresponding to the current construction personnel; S340, determining current personnel attribute information based on the construction status; S350: Output corresponding security inquiry information based on the current personnel attribute information.

[0043] Specifically, if there is only one piece of personnel attribute information associated with the sign-in information, the corresponding security inquiry information can be directly output; if there is more than one piece of personnel attribute information associated with the sign-in information, it is necessary to obtain the construction status corresponding to the current construction personnel, and then determine the current personnel attribute information corresponding to the construction personnel at this time based on the current construction status, and then output the security inquiry information based on the current personnel attribute information.

[0044] The specific steps to obtain the construction status corresponding to the current construction personnel are: The construction identification information on the safety protection equipment in the image information can be identified through an image recognition algorithm, and then the associated construction status is searched from a preset construction identification library, which is the current construction status.

[0045] The construction identification information can be the color of the safety protection equipment, one color corresponds to one construction status; or the construction status information can be directly displayed on the safety protection equipment, and the method is not limited. The construction status includes supervision, operation, and normal. If the construction status is supervision, the personnel attribute information of the construction personnel at this time is safety officer.

[0046] The construction identification database refers to a database associated with the names of construction personnel, sign-in information, personnel attribute information, and construction status.

[0047] After S320 or S350, feedback information from the construction personnel may be obtained, so as to determine whether the hoisting can be carried out normally according to the feedback information; if not, hoisting adjustment information is output, and if so, no response is given.

[0048] Feedback information includes yes and no. Voice receivers are installed at the entrance and exit of the hoisting area. When the feedback information received is yes, it is correct. When the feedback information received is no, it is necessary to output hoisting adjustment information. Hoisting adjustment information includes "need to overhaul equipment", "need to understand construction specifications", "need to understand safety supervision specifications", etc.

[0049] Further, refer to Figure 4 After the sign-in time is over, the hoisting construction monitoring method may further include S410-S460: S410, counting the construction types of the personnel attribute information corresponding to the construction personnel entering the lifting area; S420, determining whether the construction types are complete; S430, if yes, no response; S440, if not, continue to determine whether the missing construction type is a necessary type; S450, if yes, sending a temporary operation instruction to the construction personnel corresponding to the non-essential type including the missing personnel attribute information corresponding to the construction type; S460, if not, no response.

[0050] Specifically, after the sign-in time is over, the construction personnel entering the lifting area are counted to obtain the construction types in the lifting area, so as to determine whether the construction types are complete. Complete construction types refer to the complete construction types necessary for lifting. If the construction types are incomplete, it is necessary to further determine whether the missing construction types are necessary types; if so, a temporary operation instruction can be sent to the construction personnel corresponding to the non-essential types that contain the personnel attribute information corresponding to the missing construction types.

[0051] For example, hoisting requires three types of construction workers, A, B, and C; among them, A and C are necessary construction workers; B is a non-essential construction worker; therefore, if construction worker A is missing, and the personnel attribute information corresponding to B includes the personnel attribute information of A and the personnel attribute information of B; therefore, a temporary operation instruction can be sent to construction worker B, and construction worker B will wait temporarily; if the personnel attribute corresponding to B is unique, it is necessary to wait for construction worker A to enter the hoisting area.

[0052] The implementation principle of this embodiment is: Collect image information of construction workers who are about to enter the lifting area, and determine whether the construction workers are wearing safety protection equipment based on the image information. If so, receive the construction workers' sign-in information, and retrieve the associated personnel attribute information to determine whether the personnel attribute information is unique. If not, obtain the construction status corresponding to the current construction worker, and then determine the current personnel attribute information based on the construction status, and then output the corresponding safety inquiry information based on the current personnel attribute information; After the sign-in time is over, the construction types of the personnel attribute information corresponding to the construction personnel entering the lifting area are counted, and it is determined whether the construction types are complete. If not, it is further determined whether the missing construction types are necessary types; if so, a temporary operation instruction is sent to the construction personnel corresponding to the non-essential types including the personnel attribute information corresponding to the missing construction types; During hoisting, the actual hoisting parameters of the current hoisting node are obtained in real time, and it is determined whether the actual hoisting parameters match the hoisting standard parameters; if not, adjustment prompt information is output.

[0053] Based on the above method embodiment, the second embodiment of the present application discloses a BIM-based steel structure factory building hoisting construction safety monitoring system.

[0054] Reference Figure 6 As another implementation of the hoisting construction safety monitoring system, the hoisting construction safety monitoring system may further include: The image acquisition module 110 is used to acquire image information of construction personnel who are about to enter a preset lifting area before lifting; The judging module 104 judges whether the construction personnel are wearing safety protection equipment; The information receiving module 106 is used to receive the construction personnel's sign-in information when the judging module 104 judges that it is yes; The information retrieval module 107 is used to retrieve the personnel attribute information pre-associated with the check-in information based on the check-in information; The information output module 105 is used to output corresponding security inquiry information based on the personal attribute information; and is used to output entry denial information when the judgment module 104 judges that it is no.

[0055] Furthermore, the judgment module 104 will also determine whether the personnel attribute information corresponding to the construction personnel is unique; if so, the information output module 105 directly outputs the corresponding security inquiry information; if not, the information receiving module 106 will obtain the construction status corresponding to the current construction personnel; the information retrieval module 107 will determine the current personnel attribute information according to the construction status; the information output module 105 is used to output the corresponding security inquiry information based on the current personnel attribute information.

[0056] Furthermore, the hoisting construction safety monitoring system also includes: A statistics module 108, used to count the construction types of the personnel attribute information corresponding to the construction personnel entering the lifting area; The judgment module 104 is used to judge whether the construction types are complete; if so, no response is given; if not, the judgment module 104 continues to judge whether the missing construction type is a necessary type; The instruction sending module 109 is used to send a temporary operation instruction to the construction personnel corresponding to the non-essential type including the personnel attribute information corresponding to the missing construction type when the missing construction type is a necessary type.
