[0067] The following description is used to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are only examples, and those skilled in the art may think of other obvious variations.

[0068] Reference Figure 1 As shown, a comprehensive control method based on real-time monitoring of digital construction sites includes:

[0069] Obtain the coverage area that needs to be managed and controlled on the construction site, and obtain the monitoring distribution architecture that has been set up in the coverage area. The monitoring distribution architecture consists of monitoring points and monitoring equipment, and the monitoring equipment is set up at the monitoring points;

[0070] Obtain at least one key area of ​​the construction site in the coverage area of ​​the management and control service;

[0071] Calculate the monitoring duplication of the monitoring distribution architecture, and determine whether the monitoring duplication is greater than a first preset value. If not, do not perform any processing. If yes, deduplicate the monitoring distribution architecture.

[0072] The parts of the coverage area of ​​the management and control service other than the key areas are summarized as non-key areas;

[0073] Identify blind spots in key areas of management and control services to obtain the first coverage blind spot;

[0074] Identify blind spots in non-critical areas of management and control services to obtain the second coverage blind spot;

[0075] Adding new monitoring points and new monitoring equipment in the first coverage blind area and the second coverage blind area to obtain at least one additional plan;

[0076] Calculate the additional costs of the additional plans, and select the additional plan with the smallest additional cost as the target additional plan;

[0077] The newly added monitoring points and newly added monitoring equipment of the target additional plan are merged into the monitoring distribution architecture to obtain the monitoring distribution optimization architecture;

[0078] Use the monitoring equipment added in the monitoring distribution optimization architecture to monitor, and provide management and control services when abnormalities occur in the monitoring screen.

[0079] In this solution, the digital construction site is comprehensively controlled, and comprehensive control mainly relies on comprehensive monitoring. The construction involved in different locations in the construction site is different. The construction in some places is simple, involving fewer people and fewer dangers. Therefore, there is no need to conduct too much monitoring for such places. It is only necessary to ensure monitoring coverage. The monitoring viewing angle is not required to be high. However, for construction with higher complexity or higher risk, in order to ensure the quality of construction and prevent construction personnel from performing dangerous operations, it is necessary to ensure that these locations can be monitored from multiple angles, so that there will be no blind spots when monitoring the construction at these locations. Therefore, in this solution, the key areas are formed, and the rest of the coverage area is regarded as non-key areas, and different degrees of monitoring are supplemented for the key areas and non-key areas;

[0080] In addition, the monitoring equipment originally set up on the construction site needs to be analyzed, because there may be many overlapping parts between these monitoring equipment. Therefore, the efficiency of the use of monitoring equipment needs to be improved. That is, the monitoring equipment can be reduced to control costs. The addition of monitoring equipment will occur after deduplication. If deduplication does not occur, additional monitoring equipment will be added.

[0081] Obtaining the monitoring distribution architecture that has been set up in the coverage area includes the following steps:

[0082] The monitoring equipment is identified in the coverage area. When the monitoring equipment is identified, the location of the monitoring equipment is obtained as the monitoring point. The layout of all monitoring points and monitoring equipment constitutes the monitoring distribution architecture.

[0083] Reference Figure 2 As shown, in the coverage area of ​​the management and control service, obtaining at least one key area of ​​the construction site includes the following steps:

[0084] Evenly divide the coverage area of ​​the management and control service into at least one area to be identified;

[0085] Obtain the time percentage of construction workers appearing in the area to be identified, and obtain the average number of construction workers appearing in the area to be identified;

[0086] Obtaining the process difficulty of the construction steps in the area to be identified, and obtaining the danger level of the construction steps in the area to be identified;

[0087] Accumulate the average number of people in at least one area to be identified to obtain the total number of people;

[0088] Accumulate the process difficulty of at least one area to be identified to obtain a total difficulty;

[0089] Accumulating the danger level of at least one area to be identified to obtain a total danger level;

[0090] Use the key coefficient formula to calculate the key coefficient of the area to be identified;

[0091] The to-be-identified region whose key coefficient is greater than the second preset value is regarded as the key region;

[0092] The key coefficient formula is as follows:

[0093]

[0094] Among them, A is the key coefficient of the area to be identified, a is the time proportion of the area to be identified, b is the average number of people in the area to be identified, B is the total number of people, c is the process difficulty of the area to be identified, C is the total difficulty, d is the danger level of the area to be identified, and D is the total danger.

[0095] Key areas are construction locations where the construction process is more complicated or there are certain dangers. Multi-angle monitoring is required at these locations. Because of the obstruction of buildings or debris on the construction site, monitoring from a single angle may not be able to accurately obtain the situation of the construction workers. The identification of key areas is evaluated from three aspects: construction duration, difficulty and danger, and each aspect is presented in the form of a proportion. In this way, the results of the three situations can be superimposed.

[0096] Reference Figure 3 As shown, calculating the monitoring duplication of the monitoring distribution architecture includes the following steps:

[0097] Obtaining the field of view of the monitoring device, and obtaining the monitoring area of ​​the monitoring device in the coverage area based on the field of view of the monitoring device and the coordinates of the monitoring points of the monitoring device;

[0098] Obtaining one of the at least one monitoring area as a target monitoring area;

[0099] Obtain the total area of ​​the overlapping parts of the target monitoring area and the remaining monitoring areas as the overlapping area;

[0100] The overlapping area is divided by the covered area to obtain the monitoring repetition coefficient of the target monitoring area;

[0101] The target monitoring area traverses at least one monitoring area, and the monitoring repetition coefficient of at least one target monitoring area is accumulated to obtain the monitoring repetition degree of the monitoring distribution architecture.

[0102] The monitoring duplication evaluates the overlapping parts of the monitoring in the monitoring distribution architecture. When the overlapping parts are too large, it means that some monitoring devices can be deleted, because most of their monitoring effects can be replaced by other monitoring devices, and the monitoring distribution architecture will be supplemented in the future. Therefore, deletion will not affect the monitoring effect.

[0103] Deduplication of the monitoring distribution architecture includes the following steps:

[0104] A target monitoring area whose monitoring repetition coefficient is greater than a preset coefficient is obtained, and monitoring points and monitoring equipment corresponding to the target monitoring area are removed from the monitoring distribution architecture.

[0105] Reference Figure 4 As shown, blind spot identification is performed in a key area of ​​the management and control service to obtain a first coverage blind spot, including the following steps:

[0106] The longest line segment length that can be included in the monitoring area is used as the preset distance;

[0107] Acquire at least one monitoring device whose distance to the key area is less than a preset distance as a characteristic monitoring device;

[0108] At least one identification point is evenly arranged in the key area;

[0109] Determine whether the recognition point is monitored 360 degrees by the feature monitoring device. If so, the recognition point is used as the target recognition point. If not, no processing is performed.

[0110] When the number of target identification points is less than the preset number, the key area is used as the first coverage blind area.

[0111] The identification of blind spots in critical areas is different from that in non-critical areas. Non-critical areas only need to ensure that they are covered by monitoring, but in critical areas, it is necessary to ensure that the construction process of construction personnel is fully monitored to prevent the construction quality from being affected or safety problems from being caused by monitoring omissions. In order to determine whether a critical area is a blind spot, first, the preset distance is determined. According to the method of obtaining the preset distance, the farthest monitoring distance of the monitoring equipment must be less than the preset distance. Therefore, when the distance to the critical area is greater than the preset distance, the monitoring equipment will not monitor the critical area. Therefore, it does not need to participate in the judgment. At the same time, the critical area is approximated and evaluated using identification points. When most of the identification points can be monitored 360 degrees, it means that the critical area can be approximately regarded as being monitored 360 degrees. Otherwise, it means that there are many areas in the critical area that cannot be monitored 360 degrees and cannot be ignored. Therefore, it is necessary to supplement the monitoring equipment.

[0112] Reference Figure 5 As shown, performing blind spot identification in a non-critical area of ​​the management and control service to obtain a second coverage blind spot includes the following steps:

[0113] Acquire at least one monitoring device whose distance from the key area is less than a preset distance as a calibration monitoring device;

[0114] Evenly divide the non-critical area into at least one sampling area;

[0115] Determine whether the sampling area is monitored by one of the calibration monitoring devices. If so, no processing is performed. If not, the sampling area is used as the second coverage blind area.

[0116] In non-critical areas, it is sufficient to ensure that the location is monitored, because the construction in non-critical areas is simple and the risk is not high. Therefore, there is no need for excessive monitoring. Therefore, the non-critical areas are divided to determine whether each sampling area can be monitored. The calibration monitoring equipment involved in the identification is also determined based on the preset distance. This can reduce the number of calibration monitoring equipment involved in the identification and judgment, thereby improving the detection efficiency.

[0117] Reference Figure 6As shown, adding new monitoring points and new monitoring equipment in the first coverage blind area and the second coverage blind area to obtain at least one additional solution includes the following steps:

[0118] Evenly setting at least one supplementary point in the first coverage blind area and the second coverage blind area;

[0119] Forming at least one supplementary point set, the supplementary point set consisting of i of the at least one supplementary point, where i ranges from 1 to n, and n is the total number of the at least one supplementary point;

[0120] The supplementary points in the supplementary point set are used as new monitoring points, and new monitoring equipment is set at the new monitoring points to form a preliminary plan for additional installations;

[0121] The monitoring distribution architecture is supplemented by using an additional preparation plan to obtain a monitoring distribution supplement architecture;

[0122] Determine whether the monitoring distribution supplementary architecture can perform 360-degree monitoring of the first coverage blind area and monitor the second coverage blind area. If so, the additional preparation plan will be used as the additional plan. If not, no processing will be performed.

[0123] According to common sense, when adding monitoring equipment, it is necessary to add it within the first coverage blind area and the second coverage blind area, and then supplementary points can be used as additional points. At least one supplementary point set constitutes all possible combinations of at least one supplementary point. Therefore, at least one supplementary point set approximately constitutes all possibilities for additions. Therefore, for the preliminary plan for additional installations generated by at least one supplementary point set, after using the preliminary plan for additional installations to supplement the monitoring distribution architecture, it is determined whether the first coverage blind area can be monitored 360 degrees and whether the second coverage blind area is covered by monitoring. Thus, an additional installation plan that meets the monitoring needs can be selected. However, according to common sense, the more new monitoring equipment is added in the additional installation plan, the greater the cost. Therefore, in order to control costs, a low-cost plan is selected for the final addition.

[0124] Calculating the additional cost of the additional plan includes the following steps:

[0125] The cost of the newly added monitoring equipment is obtained, and the cost of the newly added monitoring equipment is multiplied by the number of newly added monitoring equipment in the additional plan to obtain the additional cost of the additional plan.

[0126] Merging the newly added monitoring points and newly added monitoring equipment of the target additional plan into the monitoring distribution architecture to obtain the monitoring distribution optimization architecture includes the following steps:

[0127] The newly added monitoring points and newly added monitoring equipment of the target additional plan are taken as monitoring points and monitoring equipment, and incorporated into the monitoring distribution architecture to obtain the monitoring distribution optimization architecture.

[0128] Furthermore, the present solution also proposes a storage medium on which a computer-readable program is stored. When the computer-readable program is called, the above-mentioned all-round management and control method based on real-time monitoring of digital construction sites is executed.

[0129] It is understandable that the storage medium may be a magnetic medium, such as a floppy disk, a hard disk, or a magnetic tape; an optical medium, such as a DVD; or a semiconductor medium, such as a solid state drive (SSD).

[0130] To sum up, the advantages of the present invention are: by generating key areas and non-key areas, the monitoring distribution architecture is deduplicated, and based on this, the first coverage blind area and the second coverage blind area are generated, and the most economical way is used to supplement the monitoring with different focuses in the first coverage blind area and the second coverage blind area. In this way, it can satisfy the all-round monitoring of key areas and the conventional monitoring of non-key areas, and at the same time, it can effectively control costs. Furthermore, when abnormalities occur in the construction process, they can be discovered in time without omissions, and targeted management and control can be made, which can effectively guarantee the construction quality and at the same time, ensure construction safety.
