[0002] In order to ensure the safety and stability of highway tunnel construction, it is necessary to monitor and warn the highway tunnel construction site. Generally, monitoring and warning of highway tunnel construction sites are completed by multiple managers.

Together with the embodiments of the present invention, they are used to explain the present invention and do not constitute a limitation of the present invention. In the accompanying drawings:

[0091] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0092] The embodiment of the present invention provides a highway tunnel construction early warning method based on BIM, such as Figure 1 As shown, including:

[0093] S1. Identify the events to be warned in the BIM model of the highway tunnel construction site;

[0094] S2. Warning the event to be warned to the warning object of the event to be warned;

[0095] S3. When the warning object views the BIM model, the event development information of the event to be warned in the BIM model is continuously tracked;

[0096] S4, a tracking perspective template for generating event development information;

[0097] S5. Based on the tracking perspective template, guide the warning object to track and view the event development information.

[0098] In the above technical solution:

[0099] The BIM model is a three-dimensional simulation model of the highway tunnel construction site based on BIM technology, which includes the location of workers, construction equipment, and monitoring information of various monitoring sensors (such as gas sensors, temperature and humidity sensors, etc.) at the highway tunnel construction site.

[0100] Events to be warned are warning events that require safety or abnormal warnings at highway tunnel construction sites, such as the presence of harmful gases at highway tunnel construction sites; events to be warned have warning targets, who are generally management personnel at highway tunnel construction sites; warning targets of events to be warned are notified of the events to be warned, and the warning targets can be notified of the warnings.

[0101] When the warning object views the BIM model, the event development information of the event to be warned in the BIM model is continuously tracked. The event development information is information that reflects the event development of the event to be warned. For example, if the event to be warned is the appearance of harmful gases in the construction site of a highway tunnel, the event development information includes the appearance location and concentration changes of the harmful gases.

[0102] Generate a tracking perspective template for event development information. The tracking perspective template is a perspective template for the system to use to guide the warning object to track and view event development information. Based on the tracking perspective template, the warning object is guided to track and view event development information, and the warning object can learn about the development of the event to be warned.

[0103] This application introduces a BIM model to automatically identify events to be warned in the BIM model of the highway tunnel construction site. When identified, an alert is issued to the warning object, eliminating the need for management personnel to manually monitor and warn the highway tunnel construction site, reducing labor costs and improving monitoring and warning efficiency. Secondly, it automatically and continuously tracks the event development information of the events to be warned in the BIM model, and based on the tracking perspective template, guides the warning object to track and view the event development information, helping the warning object to timely and comprehensively understand the event development of the events to be warned, further improving the monitoring and warning efficiency.

[0104] In one embodiment, the tracking perspective template for generating event development information includes:

[0105] Sorting each information item in the generated event development information according to the order in which the information is generated to obtain an information item sequence;

[0106] Divide the first i information items in the information item sequence into N information item sets; wherein the information type set of each information item in each information item set matches a standard information type set;

[0107] N first viewing perspectives are created in the BIM model; wherein each first viewing perspective corresponds to each information item set one by one, a first display area of ​​all information items in the corresponding information item set is included in the first viewing perspective visible range of each first viewing perspective, and the shortest distance between the first display area and the range boundary of the first viewing perspective visible range falls within the first standard distance interval;

[0108] Generate a perspective switching rule for each first viewing perspective; wherein the perspective switching rule is to sequentially switch each first viewing perspective corresponding to each information item set according to the sequence position of each earliest generated information item in each information item set in the information item sequence;

[0109] Generate a first sub-template based on each first viewing perspective, each set of information items corresponding to each first viewing perspective, and a perspective switching sequence;

[0110] Ki second viewing perspectives are created in the BIM model; wherein each second viewing perspective corresponds to the last Ki information items in the information item sequence; wherein K is the total number of information items, Ki ≥ T, and T is the number threshold; within the second viewing perspective visible range of each second viewing perspective, a second display area of ​​the corresponding information item and an information change prediction area of ​​the corresponding information item are included, and the shortest distances of the second display area and the information change prediction area from the range boundary of the second viewing perspective visible range are both within the second standard distance interval;

[0111] generating a perspective-keeping rule for each second viewing perspective;

[0112] generating a second sub-template based on each second viewing perspective, each information item corresponding to each second viewing perspective, and a perspective maintaining rule;

[0113] A tracking viewpoint template is generated based on the first sub-template and the second sub-template.

[0114] In the above technical solution:

[0115] N is a positive integer; different information items can exist in different information item sets; the information type set of each information item in each information item set has all the information types of each information item in the information item set; a standard information type set is pre-set, and the standard information type set has the information types of information items that need to be displayed under the same viewing perspective, for example: the information types in the standard information type set are the occurrence locations and changing concentrations of multiple harmful gases in the same construction area in a highway tunnel construction site; the first i information items are divided into N information item sets, so that the information type set of each information item in each information item set matches a standard information type set, so that when creating a one-to-one corresponding first viewing perspective for each information item set, the information item has a first display area in the BIM model, and the first viewing perspective visible range of each first viewing perspective contains the first display area of ​​all information items in its corresponding information item set, and the information items that need to be displayed under the same viewing perspective can be displayed under the same first viewing perspective.

[0116] The first visible range of the first viewing perspective refers to the visible range of the first viewing perspective on the BIM model; the first standard distance interval can be 5 cm to 10 cm, and the shortest distance between the first display area and the range boundary of the visible range of the first perspective is constrained to fall within the first standard distance interval, so that the first viewing perspective is used to view the information items in the corresponding information item set for display. The viewing angle utilization rate is higher, avoiding waste in viewing angle utilization.

[0117] A first sub-template is generated based on each first viewing perspective, each information item set corresponding to each first viewing perspective, and a perspective switching sequence; when using the first sub-template, the BIM model is viewed from each first viewing perspective in sequence according to a preset perspective switching speed (which can be set in advance by technical personnel), and each time a first viewing perspective is switched to, each information item in the information item set corresponding to the first viewing perspective switched to is controlled to be displayed on the BIM model.

[0118] The generation process of the perspective switching rule means that: each information item set corresponding to the first viewing perspective has an earliest generated information item, the sequence position of this earliest generated information item in the information item sequence is determined, and it is associated with the first viewing perspective corresponding to the information item set where the earliest generated information item is located. The perspective switching rule is to switch each first viewing perspective in the order of the sequence position associated with each first viewing perspective. The purpose of this is to enable the warning object to give priority to viewing the development of other events (other information items in the information item set where the earliest generated information item is located) under the first viewing perspective where the development of the event that occurred first (the earliest generated information item) is located when using the first sub-template; T is the number threshold, which can be set in advance by the technical staff.

[0119] The second viewing perspective visible range of the second viewing perspective refers to the visible range of the second viewing perspective in the BIM model; the information change prediction area of ​​the information item refers to the area that will change the display when the information item changes, for example: the information item is a harmful gas distribution area, and the new diffusion area of ​​the harmful gas can be predicted based on the wind direction, wind speed, etc. in the area, and the new diffusion area is the information change prediction area; the second standard distance interval can be 3 cm to 12 cm; the shortest distances between the second display area and the information change prediction area and the range boundary of the second viewing perspective visible range are constrained to fall within the second standard distance interval, and similarly, this is also to improve the utilization rate of the second viewing perspective.

[0120] The perspective keeping rule refers to the rule of keeping the viewing screens of each second viewing perspective displayed simultaneously; a second sub-template is generated based on each second viewing perspective, the one-to-one corresponding information items of each second viewing perspective and the perspective keeping rule. When the second sub-template is used, the viewing screens of each second viewing perspective are displayed to the warning object at the same time, and each time a viewing screen of a second viewing perspective is displayed, the viewing screen contains the information item corresponding to the second viewing perspective.

[0121] A tracking viewpoint template is generated based on the first sub-template and the second sub-template. When the tracking viewpoint template is used, the first sub-template is used first, and then the second sub-template is used.

[0122] When the embodiment of the present invention generates a tracking perspective template for event development information, it first divides the front information items in the information item sequence into information item sets, creates first viewing perspectives corresponding to each information item set and perspective switching rules for each first viewing perspective, so that the warning object can sequentially understand the earlier event development of the event to be warned in the case of perspective switching; secondly, creates second viewing perspectives corresponding to the back information items in the information item sequence and perspective keeping rules for each second viewing perspective, so that the warning object can simultaneously understand the latest event development of the event to be warned while maintaining multiple perspectives at the same time; in this way, it helps the warning object to understand the early change process of the event to be warned, understand important factors such as the cause of the event, and fully understand the latest situation of the event to be warned in the later stage, make decisions on response strategies, etc., which is particularly applicable, improves the experience of the warning object and its work efficiency, and improves the rationality of the generation of tracking perspective templates.

[0123] In one embodiment, before identifying the events to be warned in the BIM model of the highway tunnel construction site, the method further includes:

[0124] Identify the need for additional information on the BIM model;

[0125] Based on the needs for information supplementation, formulate information supplementation collection tasks;

[0126] Sending information supplementary collection task orders to various information collection terminals in the highway tunnel construction site;

[0127] When each information collection terminal transmits back the supplementary collection information obtained by executing the information supplementary collection task, the supplementary collection information is represented in the BIM model.

[0128] In the above technical solution:

[0129] The information supplement demand refers to the situation information of the monitored highway tunnel construction site that is temporarily missing in the BIM model; the information supplement collection task is to control the various information collection terminals in the highway tunnel construction site to supplement the collection of the temporarily missing situation information indicated by the information supplement demand; the information supplement collection task command is sent to the various information collection terminals in the highway tunnel construction site, and each information collection terminal executes the information supplement collection task and obtains the supplementary collection information and then transmits it back, and the supplementary collection information is represented in the BIM model.

[0130] The embodiment of the present invention identifies the information supplementation needs of the BIM model, automatically formulates and issues corresponding information supplementation collection tasks, and represents the supplementary collection information in the BIM model, thereby improving the comprehensiveness of BIM model construction and improving the comprehensiveness of subsequent identification of information to be warned.

[0131] In one embodiment, after guiding the warning object to track and view the event development information based on the tracking perspective template, the method further includes:

[0132] Determine and mark the locations of multiple on-site personnel affected by the event to be warned from the BIM model;

[0133] Display circled prompt information to the warning object;

[0134] When the warning object starts to perform a circle selection operation in the BIM model to form a circled area, every time at least one new personnel position falls into the circled area at the same time, a warning strategy list for each on-site personnel at each personnel position that falls into the circled area is generated;

[0135] The list of each early warning strategy is set next to the personnel position of the corresponding on-site personnel, and displayed to the early warning object;

[0136] Predicting a new enlarged area of ​​the selected area when at least one new person position simultaneously falls into the selected area;

[0137] Based on the newly expanded area and the warning strategy list, determine the expansion progress and pre-selected warning strategies corresponding to each warning strategy list;

[0138] When the warning object continues to circle the selection operation, if the circled area is expanded to any expansion progress, the pre-selected warning strategy corresponding to the expansion progress reached by the circled area is displayed;

[0139] When the warning object performs a circle selection operation and the expansion progress of the circled area is greater than or equal to the duration threshold, a pre-selected warning strategy corresponding to the expansion progress of the circled area is executed.

[0140] In the above technical solution:

[0141] Being affected by events to be warned means that the occurrence and development of events to be warned may pose threats to the safety of on-site personnel.

[0142] The circle selection prompt information is to prompt the warning object to circle the information of the on-site personnel who need to be warned; after receiving the prompt, the warning object can circle the positions of multiple on-site personnel affected by the event to be warned in the BIM model according to its own judgment.

[0143] There are multiple warning strategies suitable for warning on-site personnel in the warning strategy list, which can be comprehensively determined based on the distance between the current location of the on-site personnel and the location of the event to be warned, the emergency supplies around the current location of the on-site personnel (such as gas masks, fire extinguishers, etc.), the location of the escape exit, etc. For example, if the event to be warned is the generation of harmful gases, the on-site personnel are close to the location of the event to be warned, and there is a gas mask cabinet nearby, then a warning strategy is formulated to go to the gas mask cabinet to get the gas mask and wear it.

[0144] When the warning object starts to perform a circle selection operation in the BIM model to form a circled area, every time at least one new personnel position falls into the circled area at the same time, a warning strategy list for each on-site personnel newly falling into the circled area is generated, and each warning strategy list is set next to the personnel position of its corresponding on-site personnel and displayed to the warning object; the circle selection operation is similar to using a pointer to select a box on a computer desk.

[0145] When predicting the new expanded area of ​​the selected area when at least one new personnel position falls into the selected area at the same time, it can be determined according to the personnel position of the on-site personnel closest to the current selected area in the BIM model and the expansion change direction of the current selected area, that is, the new expanded area is the non-overlapping area between the expanded selected area and the current selected area when the current selected area is expanded to have the next indication that a new personnel position falls into it at the same time.

[0146] Based on the newly expanded area and the warning strategy list, multiple groups of one-to-one corresponding expansion progress and pre-selected warning strategies corresponding to each warning strategy list are determined, the expansion progress is a plurality of progresses in the middle of the expansion of the current circled area to the expanded circled area, the pre-selected warning strategy is the warning strategy in the warning strategy list, the number of expansion progress is consistent with the number of pre-selected warning strategies, when the warning object continues to perform the circle selection operation, the current circled area will be expanded, if the expansion of the circled area reaches any expansion progress, the pre-selected warning strategy corresponding to the expansion progress reached by the expansion of the circled area is displayed, at this time, if the warning object performs the circle selection operation to maintain the expansion progress reached by the circled area (that is, stop continuing to expand the circled area) greater than or equal to the time threshold (the time threshold can be, for example, 3 seconds), the pre-selected warning strategy corresponding to the expansion progress reached by the expansion of the circled area is executed.

[0147] Generally, when the warning object wants to warn the on-site personnel according to the development of the event to be warned, it is necessary to determine the appropriate warning strategy for each on-site personnel one by one, and it is also necessary to issue the warning command one by one; the warning object of the embodiment of the present invention can circle the BIM model, and during the circle selection process, the system will adaptively prompt the on-site personnel of the personnel position newly falling into the circled area with a list of appropriate warning strategies, and the warning object does not need to stop circling, and while expanding the circled area, the pre-selected warning strategy will be displayed to it according to the expansion progress. When the warning object believes that the pre-selected warning strategy displayed to it is appropriate, the warning object only needs to circle the operation to keep the expansion progress of the circled area greater than or equal to the time threshold, and the system will execute the pre-selected warning strategy corresponding to the expansion progress of the circled area; it can quickly, comprehensively and accurately complete the issuance of warning commands to multiple on-site personnel affected by the event to be warned, which is particularly applicable.

[0148] In one embodiment, after guiding the warning object to track and view the event development information based on the tracking perspective template, the method further includes:

[0149] Receive the event processing strategy of the event to be warned input by the warning object;

[0150] Execute incident handling strategies;

[0151] Obtain information on the execution of event handling strategies;

[0152] Calculate the evaluation value of the execution status information;

[0153] Output the evaluation value and execution status information to the warning object;
