Description

Technical Field

[0001] The present invention relates to the technical field of construction site management, and in particular to an intelligent management system for a construction site based on an Internet of Things cloud platform. Background Art

[0002] The construction industry combines the industrial Internet platform with 5G+ Internet of Things technology as the main technology, and combines new technologies such as big data, artificial intelligence, BIM, GIS, digital twins, etc. to provide construction companies with engineering project management for the entire construction process, smart construction site management, and BIM-based integrated design and construction management applications, empowering the company's building design, construction, management and other processes.

[0003] However, in the existing technology, the construction site is unable to conduct risk warnings from both the overall and local directions. In addition, when issuing local risk warnings, it is impossible to conduct safety analysis on the power control on site, and the power control and power usage are not combined for synchronous analysis, resulting in low efficiency in power safety monitoring and control. At the same time, it is impossible to conduct operational safety analysis on mechanical equipment on the construction site, so that the mechanical operation points on site cannot be planned, and potential risks cannot be warned in time, resulting in low efficiency in safety management of the construction site.

[0004] In view of the above technical defects, a solution is now proposed. Summary of the invention

[0005] The purpose of the present invention is to solve the above-mentioned problems and to propose an intelligent management system for construction sites based on the Internet of Things cloud platform.

[0006] The purpose of the present invention can be achieved through the following technical solutions:

[0007] An intelligent management system for a construction site based on an Internet of Things cloud platform, comprising an intelligent management platform, wherein the intelligent management platform is communicatively connected to an overall risk warning unit and a local risk warning unit;

[0008] The overall risk warning unit is used to carry out overall risk warning for the construction site, conduct overall risk analysis for the real-time operating construction site, obtain the construction period of the construction site according to the on-site construction progress, obtain the overall risk warning coefficient of the construction site during the construction period, generate an overall high-risk warning signal or an overall low-risk warning signal based on the overall risk warning coefficient comparison, and send it to the intelligent management platform;

[0009] The local risk warning unit is connected to the power safety analysis unit, the mechanical operation analysis unit and the construction site analysis unit. The power safety analysis unit is used to conduct safety analysis on the power control equipment in the construction site and conduct reasonable analysis and control based on the current power usage of the construction site.

[0010] The mechanical operation analysis unit is used to perform mechanical operation analysis on mechanical equipment in the construction site, and the construction site analysis unit is used to perform operation safety analysis on the construction site.

[0011] As a preferred embodiment of the present invention, the operation process of the power safety analysis unit is as follows:

[0012] According to the electricity usage of the construction site in the current period, regional screening is performed, and the screening is divided into power-consuming areas and non-power-consuming areas. During the on-site construction process, power outages in the power-consuming areas and power supply in the non-power-consuming areas are set as area conversion operations; the maximum extendable time for a single action of electrical machinery and equipment in the power-consuming areas within the construction site is obtained; if the maximum extendable time for a single action of electrical machinery and equipment in the power-consuming areas within the construction site does not exceed the maximum extendable time threshold, the current action execution is set as a power-off risk action; if the maximum extendable time for a single action of electrical machinery and equipment in the power-consuming areas within the construction site exceeds the maximum extendable time threshold, the current action execution is set as a power-off controllable action.

[0013] As a preferred implementation of the present invention, a floating frequency of the time it takes for the electric machinery and equipment in the non-electricity area of ​​the construction site to complete the operation without electricity is obtained. If the floating frequency of the time it takes for the electric machinery and equipment in the non-electricity area of ​​the construction site to complete the operation without electricity exceeds a floating frequency threshold, the current action execution device is defined as an action with uncontrollable operation duration; if the floating frequency of the time it takes for the electric machinery and equipment in the non-electricity area of ​​the construction site to complete the operation without electricity does not exceed the floating frequency threshold, the current action execution device is defined as an action with controllable operation duration;

[0014] When a zone change operation is required in a construction area, when the current power-consuming area executes a power-off risk action or the non-power-consuming area executes an action with uncontrollable operating duration, a safety analysis is performed on the power control end. When the power control end receives the zone change operation instruction, it is necessary to distribute and send instructions to all construction personnel in the power-consuming area or the non-power-consuming area, and after receiving the action execution end instructions from all construction personnel, the power control end executes the zone change operation. If the zone change operation must be executed immediately, the construction personnel who have not sent the action execution end instruction will be paused after the single action is completed or the action to be executed will be paused.

[0015] As a preferred embodiment of the present invention, when the current power consumption area executes a controllable power-off action or the non-power consumption area executes a controllable operation time action, a safety analysis is performed on the power consumption end, and when the power control end executes the area change operation, a pause command is sent to the power consumption end, and the interval time floating span between the moment when the power consumption end in the construction area receives the pause command and the moment when the power control end executes it is obtained. If the interval time floating span between the moment when the power consumption end in the construction area receives the pause command and the moment when the power control end executes it exceeds the interval time floating span, it is determined that the operating efficiency of the power consumption end is affected and the execution efficiency of the power control end is reduced, and a power change control signal is generated and sent to the administrator terminal.

[0016] As a preferred embodiment of the present invention, the operation process of the mechanical operation analysis unit is as follows:

[0017] The locations of mechanical equipment in the construction site are marked as mechanical operating points, and mobile points and fixed points are divided according to the operating characteristics of the mechanical equipment. The operating actions of the mechanical equipment are analyzed, and the operating actions that directly act on the mechanical parts and cause the movement of the mechanical parts are marked as executing the main actions; the additional actions generated by the mechanical parts receiving kinetic energy during the operating actions of the mechanical equipment are marked as executing external actions.

[0018] As a preferred embodiment of the present invention, the operation area of ​​the current mechanical device performing the main action and the maximum operation area of ​​the corresponding adjacent mechanical device performing the external action at the adjacent mechanical operation point are obtained, and the intersection of the action trajectories of the corresponding mechanical parts of the two mechanical devices are obtained according to the operation area, and marked as collision intersections, and the number is not unique;

[0019] After obtaining different operating frequencies set for the corresponding machines at adjacent mechanical operating points in the construction area, the shortening speed of the corresponding straight-line spacing of the mechanical parts of the adjacent mechanical equipment when the mechanical parts have not reached the collision intersection and the single maximum reduction span of the minimum peak of the corresponding straight-line spacing of the mechanical parts when the mechanical parts of the adjacent mechanical equipment have not reached the collision intersection are obtained; and the shortening speed of the corresponding straight-line spacing of the mechanical parts when the mechanical parts of the adjacent mechanical equipment have not reached the collision intersection and the single maximum reduction span of the minimum peak of the straight-line spacing of the mechanical parts when the mechanical parts of the adjacent mechanical equipment have not reached the collision intersection are compared with the straight-line spacing shortening speed threshold and the single maximum reduction span threshold, respectively.

[0020] As a preferred embodiment of the present invention, if the shortening speed of the straight-line spacing of the corresponding mechanical parts when the mechanical parts of adjacent mechanical equipment have not reached the collision intersection exceeds the straight-line spacing shortening speed threshold, or the single maximum reduction span of the minimum peak of the straight-line spacing of the corresponding mechanical parts when the mechanical parts of adjacent mechanical equipment have not reached the collision intersection exceeds the single maximum reduction span, a mechanical operation risk signal is generated and sent to the intelligent management platform; if the mechanical operation points of the adjacent mechanical equipment are fixed points and fixed points, the operating frequency or operating time of the adjacent mechanical equipment is set, and the points of the same type of mechanical equipment in the construction area are staggered.

[0021] As a preferred embodiment of the present invention, after receiving the mechanical operation risk signal, the intelligent management platform controls the adjacent mechanical equipment. If the mechanical operation point of the adjacent mechanical equipment is a mobile point or a fixed point, the mechanical equipment at the mobile point is reset according to the construction needs of the construction site. At the same time, if the point reset cost exceeds the set threshold or the remaining workload of the mobile point does not exceed the set threshold, the operating frequency of the mechanical parts of the adjacent mechanical equipment is set to stagger the overlapping of the operating trajectories, and at the same time, the operation of the adjacent mechanical equipment is monitored in real time.

[0022] As a preferred embodiment of the present invention, the operation process of the construction site analysis unit is as follows:

[0023] Obtain the proportion of time periods when the on-site road transportation speed continues to decrease during the period of increased rainfall in the area where the construction site is located, and the proportion of time periods when the frequency of mechanical equipment operation and maintenance increases during the period of increased rainfall in the area where the construction site is located; obtain the peak increase span of the overlapping time periods when the on-site road transportation speed continues to decrease and the period when the frequency of mechanical equipment operation and maintenance increases during the operation of the construction site; obtain the operation analysis coefficient of the area where the construction site is located through analysis; compare the operation analysis coefficient of the area where the construction site is located with the operation analysis coefficient threshold.

[0024] As a preferred embodiment of the present invention, if the operation analysis coefficient of the area where the construction site is located exceeds the operation analysis coefficient threshold, a regional operation high impact signal is generated and the regional operation high impact signal is sent to the intelligent management platform; if the operation analysis coefficient Y of the area where the construction site is located does not exceed the operation analysis coefficient threshold, a regional operation low impact signal is generated and the regional operation low impact signal is sent to the intelligent management platform.

[0025] Compared with the prior art, the present invention has the following beneficial effects:

[0026] 1. In the present invention, an overall risk warning is carried out on the construction site, and the overall risk analysis of the construction site is used to determine whether the current operation safety of the construction site meets the requirements, thereby ensuring the intelligent management efficiency of the construction site, and accurately evaluating the data collected through the Internet of Things.

BRIEF DESCRIPTION OF THE DRAWINGS

[0029] In order to facilitate understanding by those skilled in the art, the present invention is further described below with reference to the accompanying drawings.

[0030] Figure 1 It is the overall principle block diagram of the present invention;

[0031] Figure 2 This is a principle block diagram of the local risk warning unit in the present invention. DETAILED DESCRIPTION

[0032] In order to enable those skilled in the art to better understand the scheme of the present invention, the technical scheme in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. 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.

[0033] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present invention. The appearance of the phrase in various places in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0034] Example 1

[0035] See also Figure 1 As shown, an intelligent management system for a construction site based on an Internet of Things cloud platform includes an intelligent management platform, wherein the intelligent management platform is communicatively connected to an overall risk warning unit and a local risk warning unit;

[0036] The intelligent management platform generates an overall risk warning signal and sends it to the overall risk warning unit. After receiving the overall risk warning signal, the overall risk warning unit issues an overall risk warning for the construction site. Through the overall risk analysis of the construction site, it is determined whether the operation safety of the current construction site meets the requirements, thereby ensuring the efficiency of intelligent management of the construction site and accurately evaluating the data collected through the Internet of Things.

[0037] An overall risk analysis is conducted on the construction site in real-time operation. The construction period of the construction site is obtained according to the on-site construction progress. The average time of advance decision notification for the temporary increase in the amount of actual operation actions of the mechanical equipment at the construction site and the preset operation actions during the construction period is obtained. The average time of advance decision notification for the temporary increase in the amount of actual operation actions of the mechanical equipment at the construction site and the preset operation actions during the construction period is marked as TFS; wherein the operation action is represented by the operation of the mechanical equipment. It is understandable that the average time of advance decision notification reflects the sudden increase in the workload of the mechanical equipment, and sudden work has high hidden dangers in the actual production process.

[0038] The reciprocating floating frequency of the environmental parameters corresponding to the location of the construction site during the construction period is obtained, and the reciprocating floating frequency of the environmental parameters corresponding to the location of the construction site during the construction period is marked as WFP; wherein the environmental parameters are represented by parameters such as short-term rainfall and maximum wind force value; the overlapping duration of the peak period of material transportation volume at the construction site during the construction period and the peak period of the proportion of manual construction area are obtained, and the overlapping duration of the peak period of material transportation volume at the construction site during the construction period and the peak period of the proportion of manual construction area are marked as CDS;

[0039] Substituting the above data into the formula, we can obtain the overall risk warning coefficient G of the construction site during the construction period, where the formula is: , where fg1, fg2, and fg3 are the preset proportional coefficients corresponding to the average duration of advance decision notification, the reciprocating floating frequency of environmental parameters, and the overlapping duration of time periods, respectively, and fg1>fg2>fg3>1, and β is the error correction factor, which is 0.98;

[0040] Compare the overall risk warning coefficient G of the construction site during the construction period with the overall risk warning coefficient threshold:

[0041] If the overall risk warning coefficient G of the construction site during the construction period exceeds the overall risk warning coefficient threshold, the overall risk analysis of the construction site during the construction period is determined to be abnormal, and an overall high-risk warning signal is generated and sent to the intelligent management platform. After receiving the overall high-risk warning signal, the intelligent management platform re-plans the working period of the current construction site and conducts real-time supervision of the site;

[0042] If the overall risk warning coefficient G of the construction site during the construction period does not exceed the overall risk warning coefficient threshold, the overall risk analysis of the construction site during the construction period is determined to be normal, and an overall low-risk warning signal is generated and sent to the intelligent management platform;

[0043] Example 2

[0044] After receiving the overall low-risk warning signal, the intelligent management platform generates a local risk warning signal and sends the local risk warning signal to the local risk warning unit. Figure 2 As shown, the local risk warning unit is communicatively connected with the power safety analysis unit, the mechanical operation analysis unit and the construction site analysis unit. After receiving the local risk warning signal, the local risk warning unit generates a motor safety analysis signal, a mechanical operation analysis signal and a construction site analysis signal, and sends them to the power safety analysis unit, the mechanical operation analysis unit and the construction site analysis unit respectively;

[0045] After receiving the power safety analysis signal, the power safety analysis unit conducts a safety analysis on the power control equipment in the construction site, performs reasonable analysis and control based on the power usage of the current construction site, ensures the efficiency of power control, and avoids the risk of power accidents caused by inaccurate power usage due to untimely cross-regional communication during the construction process; judges whether the power safety of the current construction site meets the demand based on the combined analysis of power control and power usage;

[0046] Perform regional screening based on the electricity usage of the construction site in the current period, and divide the areas into power-consuming areas and non-power-consuming areas. During the on-site construction process, power outages in power-consuming areas and power supply in non-power-consuming areas are set as area conversion operations; obtain the maximum extendable time for a single action of electrical machinery and equipment in the power-consuming areas of the construction site. If the maximum extendable time for a single action of electrical machinery and equipment in the power-consuming areas of the construction site does not exceed the maximum extendable time threshold, the current action is set as a power-off risk action, such as high-pressure air conditioning, nighttime lighting and other construction; if the maximum extendable time for a single action of electrical machinery and equipment in the power-consuming areas of the construction site exceeds the maximum extendable time threshold, the current action is set as a power-off controllable action, such as equipment power control and other actions;

[0047] The floating frequency of the time it takes for the electric machinery and equipment to complete operations without electricity in the non-electricity area of ​​the construction site is obtained. If the floating frequency of the time it takes for the electric machinery and equipment to complete operations without electricity in the non-electricity area of ​​the construction site exceeds the floating frequency threshold, the current action execution device is defined as an action with uncontrollable operation duration, specifically, actions such as equipment circuit maintenance; if the floating frequency of the time it takes for the electric machinery and equipment to complete operations without electricity in the non-electricity area of ​​the construction site does not exceed the floating frequency threshold, the current action execution device is defined as an action with controllable operation duration, such as non-electricity powered transportation of the equipment, which can be stopped at any time;

[0048] When a zone change operation is required in a construction area, when the current power-using area performs a power-off risk action or the non-power-using area performs an action with uncontrollable operation duration, a safety analysis is performed on the power control end. When the power control end receives a zone change operation instruction, it is necessary to distribute and send instructions to all construction personnel in the power-using area or the non-power-using area, and after receiving the action execution end instructions of all construction personnel, the power control end performs the zone change operation. If the zone change operation must be performed immediately, the construction personnel who have not sent the action execution end instruction will be paused after the single action is completed or the action to be executed is paused; the power control end indicates the main power switch, etc.

[0049] When the current power consumption area performs a controllable power-off action or the non-power consumption area performs a controllable operation time action, a safety analysis is performed on the power consumption end. When the power control end performs a regional change operation, a pause instruction is sent to the power consumption end, and the interval time floating span between the moment when the power consumption end in the construction area receives the pause instruction and the moment when the power control end executes the instruction is obtained. If the interval time floating span between the moment when the power consumption end in the construction area receives the pause instruction and the moment when the power control end executes the instruction exceeds the interval time floating span, it is determined that the operation efficiency of the power consumption end is affected and the execution efficiency of the power control end is reduced, and a power change control signal is generated and sent to the administrator terminal. After receiving the signal, the administrator terminal supervises the execution of the regional change operation. The power consumption end is represented by the power-consuming equipment and the execution personnel.

[0050] It can be understood that in the current scenario, the power outage risk action or the uncontrollable operation duration action is given priority, and when the execution of the controllable power outage action or the controllable operation duration action in the non-power consumption area is analyzed, it indicates that there is no power outage risk action or uncontrollable operation duration action;

[0051] After receiving the mechanical operation analysis signal, the mechanical operation analysis unit performs mechanical operation analysis on the mechanical equipment in the construction site to determine whether there is an operation safety risk when multiple mechanical equipment in the construction site are in operation, thereby causing low operation efficiency of the mechanical equipment. At the same time, based on the mechanical operation analysis of the mechanical equipment, the mechanical equipment can be set according to the degree of influence to ensure efficient location planning of the mechanical equipment at the construction site and reduce safety hazards at the construction site.

[0052] The locations of mechanical equipment placed in the construction site are marked as mechanical operation points, and the mobile points and fixed points are divided according to the operating characteristics of the mechanical equipment. The operating actions of the mechanical equipment are analyzed, and the operating actions that directly act on the mechanical parts and cause the mechanical parts to move are marked as the execution of the main actions, such as the movement of the lifting beam of the hoisting machine; the additional actions generated by the mechanical parts receiving kinetic energy during the operation of the mechanical equipment are marked as the execution of external actions, such as the movement of materials due to inertia when the lifting beam of the hoisting machine is called;

[0053] The operating area of ​​the current mechanical equipment performing the main action of the adjacent mechanical operating point and the maximum operating area of ​​the corresponding adjacent mechanical equipment performing the external action are obtained, and the intersection of the action trajectories of the corresponding mechanical parts of the two mechanical equipment are obtained according to the operating area, and they are marked as collision intersections and the number is not unique. After obtaining the different operating frequencies set for the corresponding machines at the adjacent mechanical operating points in the construction area, the shortening speed of the straight-line spacing of the corresponding mechanical parts when the mechanical parts of the adjacent mechanical equipment have not reached the collision intersection and the single maximum reduction span of the minimum peak of the straight-line spacing of the corresponding mechanical parts when the mechanical parts of the adjacent mechanical equipment have not reached the collision intersection are compared with the straight-line spacing shortening speed threshold and the single maximum reduction span threshold respectively: wherein the operating area is represented by the parts of the mechanical equipment moving to the area due to the execution of the action;

[0054] If the shortening speed of the straight-line spacing of the corresponding mechanical parts exceeds the straight-line spacing shortening speed threshold when the mechanical parts of the adjacent mechanical equipment do not reach the collision intersection, or the single maximum reduction span of the minimum peak of the straight-line spacing of the corresponding mechanical parts exceeds the single maximum reduction span when the mechanical parts of the adjacent mechanical equipment do not reach the collision intersection, it is determined that there is a risk in the operation of the corresponding adjacent mechanical equipment in the construction site, and a mechanical operation risk signal is generated and sent to the intelligent management platform. After receiving the mechanical operation risk signal, the intelligent management platform controls the adjacent mechanical equipment. If the mechanical operation point of the adjacent mechanical equipment is a mobile point or a fixed point, the mechanical equipment at the mobile point is reset according to the construction needs of the construction site. At the same time, if the point reset cost exceeds the set threshold or the remaining workload of the mobile point does not exceed the set threshold, the operating frequency of the mechanical parts of the adjacent mechanical equipment is set to stagger the overlapping of the operating trajectories, and the operation of the adjacent mechanical equipment is monitored in real time; if the mechanical operation point of the adjacent mechanical equipment is a fixed point or a fixed point, the operating frequency or operating time of the adjacent mechanical equipment is set, and the same type of mechanical equipment in the construction area is staggered;

[0055] After receiving the construction site analysis signal, the construction site analysis unit conducts an operation safety analysis on the construction site, and conducts an on-site operation safety analysis on the environmental impact in the area where the construction site is located, so as to facilitate timely intervention according to weather forecasts and ensure the safe operation efficiency of the construction site;

[0056] The proportion of the time period when the on-site road transportation speed continues to decrease during the period of increased rainfall in the area where the construction site is located, and the proportion of the time period when the frequency of mechanical equipment operation and maintenance increases during the period of increased rainfall in the area where the construction site is located, are obtained, and the proportion of the time period when the on-site road transportation speed continues to decrease during the period of increased rainfall in the area where the construction site is located, and the proportion of the time period when the frequency of mechanical equipment operation and maintenance increases during the period of increased rainfall in the area where the construction site is located, are marked as DL and PL respectively; the peak increase span of the overlapping time period when the on-site road transportation speed continues to decrease and the period when the frequency of mechanical equipment operation and maintenance increases during the operation of the construction site is obtained, and the peak increase span of the overlapping time period when the on-site road transportation speed continues to decrease and the period when the frequency of mechanical equipment operation and maintenance increases during the operation of the construction site is marked as ZJ;

[0057] By formula The operation analysis coefficient Y of the area where the construction site is located is obtained, where a1, a2 and a3 are all preset proportional coefficients, and a1>a2>a3>1, and α is an error correction coefficient. When the rainfall in the area where the construction site is located exceeds the average historical rainfall in the area, the value is 0.9; conversely, when the rainfall in the area where the construction site is located does not exceed the average historical rainfall in the area, the value is 1.1;

[0058] Compare the operation analysis coefficient Y of the area where the construction site is located with the operation analysis coefficient threshold:

[0059] If the operation analysis coefficient Y of the area where the construction site is located exceeds the operation analysis coefficient threshold, the operation analysis of the area where the construction site is located is determined to be abnormal, and a regional operation high impact signal is generated and sent to the intelligent management platform. After receiving the regional operation high impact signal, the intelligent management platform monitors the weather at the construction site in real time and takes corresponding measures in time. For example, measures to reduce the speed of road traffic include draining the road or temporarily laying plates at potholes on the road. Among them, this application uses rain as a weather influencing factor, and factors such as fog are also suitable;

[0060] If the operation analysis coefficient Y of the area where the construction site is located does not exceed the operation analysis coefficient threshold, it is determined that the operation analysis of the area where the construction site is located is normal, and a regional operation low impact signal is generated and sent to the intelligent management platform;

[0061] The above formulas are obtained by collecting a large amount of data and performing software simulation, and a formula close to the actual value is selected. The coefficients in the formula are set by technicians in this field according to actual conditions;

[0062] When the present invention is in use, the overall risk warning unit is used to provide an overall risk warning for the construction site, conduct an overall risk analysis of the construction site operating in real time, obtain the construction period of the construction site according to the on-site construction progress, obtain the overall risk warning coefficient of the construction site during the construction period, generate an overall high-risk warning signal or an overall low-risk warning signal based on the overall risk warning coefficient comparison, and send it to the intelligent management platform; the local risk warning unit is communicatively connected to the power safety analysis unit, the mechanical operation analysis unit and the construction site analysis unit, the power safety analysis unit is used to perform a safety analysis on the power control equipment in the construction site, and perform reasonable analysis and control according to the current power usage of the construction site; the mechanical operation analysis unit is used to perform a mechanical operation analysis on the mechanical equipment in the construction site, and the construction site analysis unit is used to perform an operation safety analysis on the construction site.
