Disclosure of Invention
Aiming at the defects of the prior art, the invention provides a dynamic monitoring management system and a dynamic monitoring management method related to a risk source crossing process, which rely on an advanced laser monitoring technology, improve the current subway monitoring technology, utilize BIM and GIS technologies to realize real-time monitoring of a crossing area, realize dynamic demonstration and real-time analysis of the risk source crossing process by establishing a data platform for analysis and processing, greatly improve the identification, extraction, monitoring, processing and the like of risk source control, and are also beneficial to the informatization management of risk crossing.
The dynamic monitoring management system comprises a supervision platform and a real-time environment data fusion platform, wherein the supervision platform is used for fusing model data of at least one risk sub-source obtained by a BIM platform and peripheral real-time environment data of the risk sub-source peripheral environment of the GIS platform. Real-time space data of the shield machine can be acquired, and a monitoring scheme can be provided for a monitoring platform without a measuring point and an early warning scheme can also be provided for a health monitoring platform through the real-time space data; the GIS platform can also provide the spatial position data that are used for describing the geographical position relation between the risk sub source, and the supervision platform of being convenient for can be to the concentrated management and control of the risk sub source in the shield construction.
In the prior art, a GIS platform continuously acquires surrounding real-time environment data. In the crossing process of the shield tunneling machine, the monitoring data of the risk source is dynamic change; a measuring point-free monitoring platform belongs to energy consumption equipment, and the acquired monitoring data have discontinuity in time. In the invention, intermittent monitoring data can reflect continuous change of the risk neutron source; the continuous data of the GIS platform can only reflect the transient changes in the shield operation area in a very short time interval. In the monitoring platform, intermittent monitoring data and continuous data of the GIS platform are correlated with each other in a time-off mode (without fitting on a time axis) so as to obtain the deformation of the risk sub-source relative to the previous acquisition time of the untested monitoring platform. The invention does not adopt a time axis, but utilizes discontinuous monitoring data as heartbeat rhythm to fit or process continuous data of the GIS platform, so that the invention can be separated from precise timing systems such as GPS and the like. And while the operation scale is reduced to the order of magnitude of the number of discontinuous monitoring data, the abnormal point of the step change of the monitoring data can be evaluated based on continuous data. For underground construction equipment, deviation from GPS timing means that excavation efficiency is improved by times, and also means that navigation limitation of a gyroscope is separated.
In the prior art, the GIS platform can continuously acquire surrounding real-time environment data. However, in the crossing process of the shield machine, the monitoring data of the risk neutron source also dynamically changes, and a monitoring platform without a measuring point belongs to energy consumption equipment, and is difficult to monitor the risk neutron source in real time, so that the acquired monitoring data is discontinuous in time, the comprehensive evaluation of the discontinuously acquired monitoring data and the continuously acquired surrounding real-time environment data has hysteresis, and the hysteresis possibly misses the time for correcting the construction parameters, and even can cause the deformation of the risk source to be uncontrollable. Therefore, the method can reduce the hysteresis of data evaluation, can directly reflect the dynamic change process of the risk neutron source in the shield crossing process, is favorable for finding that the risk neutron source possibly has deformation in the shield crossing process, adopts a coping scheme in advance and prevents the deformation which is possibly substantially damaged from continuously evolving; the GIS platform can also provide the spatial position data that are used for describing the geographical position relation between the risk sub source, and the supervision platform of being convenient for can be to the concentrated management and control of the risk sub source in the shield construction.

Detailed Description
This is described in detail below with reference to fig. 1-2.
The BIM (Building Information Modeling) is a datamation tool applied to engineering design, construction and management, and is used for sharing and transmitting all life cycle processes of project planning, operation and maintenance by integrating datamation and informatization models of buildings, so that engineering technicians can correctly understand and efficiently respond to various Building Information, a foundation for cooperative work is provided for design teams and all parts of construction main bodies including buildings and operation units, and the BIM plays an important role in improving production efficiency, saving cost and shortening construction period.
A GIS (Geographic Information System) belongs to a specific spatial Information System, and can collect, analyze, calculate, and relate Geographic distribution data of each space with the support of the current computer Information technology. The GIS data is the most basic content, and can collect, manage and maintain the spatial geographic information of the urban building.
There is no alternative between BIM and GIS, but rather a complementary relationship. The appearance of GIS lays a foundation for the intelligent development of cities, the appearance of BIM is attached to the overall information of urban buildings, and the combination of the two creates a virtual city model attached with a large amount of city information, which is the foundation of the smart cities. Generally, the BIM is used to integrate and manage all stage information of the building itself, and the GIS is used to integrate and manage the external environment information of the building. The BIM information in the micro field and the GIS information in the macro field are exchanged and combined, so that the intelligent city building can play an irreplaceable role. In the invention, the monitoring platform is a platform which is integrated by a BIM platform and a GIS platform and is used for simulating the dynamic change of a risk sub source when a shield tunneling machine passes through a risk sub source.
The 3D measuring point-free technology can provide point cloud data with certain adoption density of effective measuring range, has higher measuring precision and extremely high data acquisition efficiency, and the sampled point cloud is massive and has tens of millions of orders of magnitude, thereby forming a discrete three-dimensional model data field based on the point cloud. The three-dimensional measuring point-free technology appears in the 90 s of the 20 th century, and is a measuring technology capable of quickly acquiring the three-dimensional coordinates of the surface of a target object under the condition of not contacting the target object, and mass three-dimensional data of the surface of the target object acquired by the three-dimensional measuring point-free technology is called point cloud. The method replaces the traditional single-point space coordinate acquisition mode of mapping with a mode of acquiring the three-dimensional coordinates of the surface of the target body in a massive and automatic mode. The three-dimensional non-measuring point technology is mainly applied to high-precision reverse three-dimensional reconstruction of a target body, tens of thousands of measuring points and even hundreds of thousands of measuring points are often needed for high-precision reverse three-dimensional modeling of the target body, the requirement of the traditional measuring means on the number of the measuring points cannot be met, and the problem is solved due to the appearance of the three-dimensional non-measuring point technology. In recent years, with the continuous development of the technology, instruments are more and more portable, the operation is more and more convenient, the application is continuously popularized in various fields, and the ground three-dimensional non-measuring point technology is also gradually applied to deformation monitoring. As a new deformation monitoring technical means, the ground three-dimensional measuring-point-free technology has unique technical advantages: monitoring points are not needed to be arranged on the deformation body, so that the work of arranging and maintaining the monitoring points is avoided; the surface three-dimensional coordinates of the deformation body can be obtained without contacting the deformation body; the field industry obtains the point cloud quickly; the point cloud density is high, and complete detail characteristics and deformation of the surface of the deformation body can be obtained after relevant processing; although the precision of the single-point positioning is not high in the traditional technical means at present, the point position precision after the surface of the target object is modeled is very high and can reach 1-2 mm. The method for monitoring the deformation of the ground surface of the mining area by using the ground three-dimensional measuring point-free technology is a hotspot of research in the field of mining subsidence at present. When the three-dimensional measuring point-free technology is used for monitoring a surface mining subsidence area, the traditional linear main section monitoring point data is replaced by planar or strip scanning point cloud data, so that the acquisition of field data information is greatly enriched, and the mining area surface deformation monitoring result is more specific; a plurality of monitoring points need to be buried underground in the traditional monitoring means, the monitoring points are difficult to maintain in a long observation period due to mining on the earth surface of a mining area, data of the monitoring points in the later period are lost after the monitoring points are damaged, the monitoring points do not need to be buried underground in a three-dimensional non-measuring point technology, the data acquisition efficiency of monitoring deformation of the earth surface of the mining area is greatly improved, and the monitoring effect is enhanced.
The risk source refers to the existing structures (such as overpasses, roads, railways and the like) on the ground surface, the existing underground spaces (such as underground shopping malls), the existing tunnels (such as subway tunnels), the existing municipal pipelines (such as urban gas pipeline tunnels) and the like. In cities, there are several risk sub-sources, so the combination of several risk sub-sources is the risk source referred to in this invention.
Example 1
The embodiment discloses a dynamic monitoring management system related to a risk source crossing process, which can acquire dynamic data of at least one risk sub-source influenced by the crossing construction of a shield machine in different periods in the crossing process of the shield machine and/or peripheral real-time environment data of the at least one risk sub-source in different periods in the crossing process of the shield machine in real time, and perform construction dynamic informatization monitoring on the at least one risk sub-source based on the dynamic data and/or the peripheral real-time environment data.
The management system includes: the system comprises a non-measuring point monitoring platform 200, a BIM platform 700, a GIS platform 800 and a supervision platform 100.
The non-measuring point monitoring platform 200 can collect monitoring data of at least one risk sub source in different periods in the process of crossing of the shield tunneling machine under the condition that a monitoring point is not set for the at least one risk sub source and the condition that the at least one risk sub source is not contacted. For example, the unterminated monitoring platform 200 may employ unmanned aerial vehicle, GPS, radar remote sensing monitoring, and laser scanning technologies.
And the GIS platform 800 is used for acquiring the peripheral real-time environment data of the at least one risk sub-source in real time. The peripheral real-time environment data comprises real-time space data between the risk sub source and the shield tunneling machine and space position data of the geographical position relation between the risk sub sources.
And the supervision platform 100 is provided with a communication interface and is used for being in communication connection with the untested monitoring platform 200 and the BIM platform. The supervision platform 100 mainly compares the static data in the BIM platform with the monitoring data acquired by the untested point monitoring platform 200 to acquire deformation data of the risk neutron source. Therefore, the supervision platform can perform dynamic informatization management on shield construction based on at least one deformation data obtained from the risk sub-source.
It includes a supervisory platform 100 and a untested monitoring platform 200. The transmission of deformation data is realized by the non-measuring point monitoring platform 200 and the BIM platform 700 in a wireless mode. Both the BIM platform and the GIS platform may be installed on a computing device. The supervisory platform 100 may also be installed on the same computing device for fusing model data of at least one risk sub-source and ambient real-time environment data of its ambient environment. The monitoring platform is a platform for simulating dynamic change of a risk sub source when the shield tunneling machine passes through the risk sub source, and data of the BIM platform 700 and data of the GIS platform 800 are fused.
On the one hand, the no-measuring-point monitoring platform 200 belongs to energy consumption equipment and is difficult to monitor a risk neutron source in real time, so that the acquired monitoring data are discontinuous in time, but how to effectively acquire the monitoring data under the condition of time discontinuity and use the monitoring data for dynamic monitoring of the risk neutron source is the technical problem to be solved by the invention. On the other hand, in the traversing process of the shield tunneling machine, the spatial position relationship between the shield tunneling machine and the risk sub-source is dynamically changed in time, and the actual morphological data of the risk sub-source is also dynamically changed, so that the monitoring data can only be part of the actual morphological data which is intermittently acquired by the non-measured point monitoring platform 200, and how to simulate the actual dynamic change process of the risk sub-source as truly and effectively as possible through the monitoring data is another technical problem to be solved by the invention. Moreover, in the shield crossing process, for example, when the risk neutron source is an overpass (such as a three-element bridge, belonging to a traffic road leading to a capital airport), the load of passing vehicles attached to the overpass is dynamically changed, so that the deformation of the risk neutron source is also caused, and therefore, how to dynamically monitor the deformation caused by the surrounding environment data is another technical problem which needs to be solved urgently.
To this end, the inventors of the present invention introduced a GIS platform. The GIS platform 800 can input the ambient real-time environmental data of the source of risk to the supervision platform 100 during the shield tunneling construction process. The supervision platform 100 is in communication connection with the GIS platform. When the real-time environmental data of the surroundings is received, the monitoring platform 100 can match at least one deformation setting threshold value corresponding to the deformation data for evaluating the at least one deformation data based on the real-time environmental data of the surroundings. The deformation data may be a sedimentation value, a rate of change of sedimentation value over time, a rate of tilt, a rate of change of tilt over time. In the case that the deformation data exceeds the deformation setting threshold, the monitoring platform 100 can send an early warning instruction to the health monitoring platform 300 and/or can send an instruction for adjusting the acquisition scheme of the acquired monitoring data to the unterminated monitoring platform 200 to the monitoring platform 100.
The surrounding environment data acquired by the GIS is acquired in real time, and the deformation data of the risk sub-source is closely related to the surrounding environment data. The supervision platform 100 can monitor the construction dynamic informatization of the risk neutron source in different shield tunneling machine crossing periods by combining the monitoring data obtained discontinuously by the non-measuring point monitoring platform 200 and the surrounding environment data obtained continuously by the GIS platform. The monitoring data is acquired by the non-measuring point monitoring platform 200 when at least one risk sub-source is monitored in the process of traversing the shield tunneling machine. During the traversing process of the shield tunneling machine, the risk source can generate deformation (such as inclination, section deformation, settlement and the like), and at the moment, the deformation can be measured through the non-measuring point monitoring platform 200. The inclination, the section deformation and the settlement can be expressed by three-dimensional coordinates through the point cloud of the measuring risk sub-source. The static data is original 3D data of a risk sub-source in the process of not performing shield crossing, and can be imported into the BIM platform through software Creo, CAD and the like. The supervision platform 100 acquires the monitoring data collected by the untested monitoring platform 200 through a communication input interface of the supervision platform. The monitoring platform 100 can acquire the monitoring data when the GIS acquires the surrounding real-time environment data. The supervision platform 100 generates a comparison result based on comparison between the monitoring data and the static data, so that the supervision platform 100 can dynamically manage and control the risk neutron source. The strength of the monitoring means of the invention is provided by the surrounding real-time environment data, which has the following advantages: 1. the non-measuring point monitoring platform 200 can acquire discontinuous monitoring data of the risk neutron source in an energy-saving manner to acquire deformation data, for example, the monitoring frequency of the non-measuring point monitoring platform 200 can be adjusted, and when the surrounding environment data has no great influence, the monitoring frequency can be reduced to reduce the energy consumption of the non-measuring point monitoring platform 200; 2. the GIS platform can also provide spatial position data for describing the geographical position relationship between the risk neutron sources, so that the supervision platform 100 can intensively manage and control the risk neutron sources in the shield construction.
Preferably, the peripheral real-time environment data includes real-time spatial data between the risk source and the shield machine continuously acquired by the GIS platform 800. The position relation between the shield cutterhead and the risk sub-source can be defined as follows: firstly, in a space mathematical model, integrally translating a risk sub-source to the position above a tunnel to be preset to form a first virtual risk sub-source; then, translating the risk sub-source in a mode that the geometric center or the gravity center of the risk sub-source coincides with the axis of the preset tunnel to form a second virtual risk sub-source, so that the preset tunnel can penetrate through the second virtual risk sub-source; secondly, in the process of moving the cutter head, if the cutter head moves into the second virtual risk sub-source, the shield cutter head can be described as passing through the risk sub-source (a second construction stage); if the cutterhead does not move into the second virtual risk sub-source, then the shield cutterhead can be described as not passing through the risk sub-source (the first construction stage); if the cutterhead has moved out of the second virtual risk sub-source, it can be described that the shield cutterhead has passed through the risk sub-source (third construction stage). The first, second and third construction stages may all be directly reflected by real-time spatial data. The monitoring platform 100 matches the real-time spatial data to obtain a corresponding first deformation setting threshold of the deformation data. The first deformation setting threshold is mainly used for determining whether to adjust the monitoring force, such as adjusting the monitoring frequency. In the case that the deformation data exceeds the first deformation setting threshold, the supervision platform 100 can issue an instruction to the untested monitoring platform 200 to adjust the interval at which the untested monitoring platform 200 collects the monitoring data. Therefore, the non-measuring point monitoring platform 200 can intermittently acquire monitoring data in a manner of implementing different monitoring strengths on at least one risk neutron source at different crossing periods of the shield machine, so that the supervision platform 100 can acquire deformation data in a manner of intermittently comparing the monitoring data with static data after the monitoring strength is adjusted, and perform construction dynamic informatization monitoring on the risk neutron source at different shield machine crossing periods based on the deformation data acquired after the monitoring strength is adjusted.
Preferably, the management system includes a health monitoring platform 300, which is primarily used for early warning. Health monitoring platform 300 is communicatively coupled to administration platform 100. The supervision platform 100 matches the corresponding second distortion setting threshold of the distortion data by means of the real-time spatial data. The second deformation sets a threshold value for whether to warn. The monitoring platform 100 sends an early warning instruction to the health monitoring platform 300 when the deformation data acquired after the monitoring force is adjusted is greater than the second deformation setting threshold corresponding to the deformation data. The health monitoring platform 300 can perform construction dynamic informatization early warning on a risk neutron source in different shield tunneling machine crossing periods based on deformation data under the condition that the monitoring platform 100 obtains the deformation data in a mode of discontinuously comparing the monitoring data after the monitoring force is adjusted with the static data.
Furthermore, preferably, the ambient real-time environmental data includes real-time spatial data between the risk source and the shield tunneling machine. The frequency of collecting the monitoring data of the untethered monitoring platform 200 is set based on the spatial data. For example, the untested monitoring platform 200 can have the second measurement frequency when the shield is passing through to the at-risk sub-source be greater than the first measurement frequency when the shield is not passing through to the at-risk sub-source. And/or the laser measurement unit 100 is capable of a second measurement frequency when the shield is passed down to the risk sub source that is greater than a third measurement frequency when the shield has passed through the risk sub source. The mode is mainly used for the non-measuring point monitoring platform 200 to implement different monitoring strength on the risk sub-source at different construction stages of the shield. For example, the risk source is a ground structure, and according to the mode, the method can be used for monitoring the settlement displacement of the structure when the shield is penetrating to the structure in a targeted manner, and specifically comprises the following steps: the change rate of the settlement displacement of the structure along with the time when the shield penetrates to the structure is larger than that of other construction stages, so that the measurement frequency is improved, the settlement rule can be effectively drawn according to the recorded data, and guidance for adjusting construction parameters such as cutter torque adjustment, tunneling speed adjustment, support increase and the like is provided for field construction; and secondly, too many measuring personnel are required to be configured on site to measure the structure, so that the measurement engineering personnel can be scheduled and dispatched according to the measurement frequency setting of the invention, and the human resource cost is saved.
Example 2
As shown in FIG. 2, the present embodiment arranges several different types of untested point monitors for the risk sub-source. The laser scanning groups of at least three non-measuring point monitors are arranged in an L shape. The arrangement density of the untested monitors in the short edge group is greater than that of the untested monitors in the long edge group. And the untested monitors of the short edge group are arranged along the long axis direction of the risk sub-source, and the untested monitors of the long edge group are arranged along the short axis direction of the risk sub-source. For example, the untethered monitors of the long edge group are laser scanners, while the untethered monitors of the short edge group are drones. On the basis of the measurement principle of the laser scanners, the laser scanners of the short-edge group acquire deformation data in the vertical direction of the risk sub-source, and the unmanned aerial vehicles of the long-edge group acquire deformation data in the short-axis direction of the risk sub-source, and then determine the inclination rate of the risk sub-source based on a mathematical principle (such as the pythagorean theorem). However, since the systematic errors of two different sets of untested monitors are different, the deviation of the tilt rate from the actual value is increased, and the engineer tends to set the tilt rate alarm threshold value to be smaller. Therefore, the probability that the inclination rate measured by the method exceeds the inclination rate alarm threshold value and the actual inclination rate does not exceed the alarm threshold value is greatly improved, so that the inclination rate measured by the method has the advantage of early warning, and engineering personnel are reminded to correct engineering parameters early so as to prevent the actual inclination rate from really exceeding the alarm threshold value or the safety threshold value. And when the scale is measured to reduce the arrangement amount of the short side of the risk sub-source, abnormal data can be recorded based on the small-density measurement data of the long side group and the large-density measurement data of the short side group, and the non-measuring point detector is further arranged at the position where the abnormal data appears in an encrypted manner, so that the non-measuring point scanner can further acquire the measurement data at the position in a targeted manner according to the L-shaped unevenness, the acquired inclination rate is closer to the actual value while having a systematic large deviation with the actual value, and reference is provided for correcting construction parameters of engineers to prevent overdressing.
Example 3
The embodiment discloses a dynamic monitoring management system related to a risk source traversing process. A preferred system is shown in figure 1.
Preferably, at least one laser scanner of the unterminated monitoring platform 200 is placed around the at-risk-source based on the geometric characteristics of the at-risk-source. For example, the risk source is a ground structure, and a contour line formed by projection of the ground structure on the ground surface is used as a geometrical feature of the ground structure. As shown in fig. 2, the contour line of a structure on the ground is approximately L-shaped. The arrangement mode of the laser scanner can scan six sides of the L-shaped structure to obtain a plurality of point clouds. The point cloud of each side is divided as a section, and the point cloud of each section is divided into a plurality of areas. For example, a point cloud is divided into a plurality of square grid regions, and a coordinate system is defined for the point cloud in each square grid region (x-axis is horizontal direction, z is vertical direction, and y is normal direction of the risk sub-source), then the coordinates of any ith point cloud are:
Pi＝(xi，yi，zi)，i＝1,2…n
the boundary of the region may be defined by xmAnd ymTwo parameters are determined:
xm≤xi≤xm+dx
zm≤zi≤zm+dz
in the formula (d)xAnd dzRespectively the length and width of the square grid.
And converting the point cloud in each area into a characteristic point, so that the point cloud acquired by the laser scanner (600) can form at least one characteristic point according to the geometric characteristics of the risk sub-source. Feature point coordinates P in any one region*＝(x*，y*，z*) It can be calculated as follows:
x*＝xm+dx/2
y*＝1/n·∑yi
z*＝zm+dz/2
wherein at least one characteristic point is used for constructing a scanning section of a risk-neutron sourceThe displacement data of the scanning section can be used as deformation data. For example, as shown in fig. 2, these may form 6 scan sections. Displacement data (p) of these cross sectionsiWill vary with time, resulting in P*Also varies with time, and thus these P*The formed set will also vary with time, P*The change of the formed set is defined as displacement data) may be used as the deformation data.
Preferably, the second three-dimensional coordinates of the point cloud are obtained as follows:
s1: at least three criterion points are set in a safe region of the risk sub-source. According to geometrical principles, at least three standard points can be used to form an absolute coordinate system. The absolute coordinate system is obtained by performing elevation control measurement, plane control measurement and three-dimensional control measurement on at least three standard points before shield construction. The elevation control measuring method comprises a leveling measuring method and an electromagnetic wave distance measurement triangulation elevation measuring method. The plane control measurement comprises corner measurement, wire measurement, GPS measurement, triangulation measurement and trilateration. The three-dimensional control measurement method comprises the combination of GPS measurement and corner measurement, wire measurement, leveling measurement and electromagnetic wave distance measurement triangulation elevation measurement. At least three prisms are arranged outside the safe area of the risk sub source to be used as standard points 400, wherein the standard points 400 are arranged to cover the whole foundation pit, for example, four standard points 400 are shown in fig. 2. According to the geometrical principle, each prism can determine the coordinates of one standard point 400, so that at least three standard points 400 are required to form an absolute coordinate system.
S2: at least three observation points 500 are arranged in the risk area of the risk sub-source and third three-dimensional coordinates in its absolute coordinate system are acquired. The third three-dimensional coordinate is obtained by measuring the observation point 500 from the known standard point 400, which is also measured by elevation control measurement, planar control measurement, and three-dimensional control measurement before each measurement of the deformation of the hazardous sub-source.
S3: a reference coordinate system determined by the laser scanner 600 is established. Preferably, the reference coordinate system is specified by an internal system in the laser scanner 600, with the position of the laser scanner 600 as the origin of the coordinate system, with certain two mutually perpendicular directions as X and Y axes in the horizontal, and with the vertical direction as the Z axis.
S4: a first three-dimensional coordinate and a point cloud of at least three observation points 500 are scanned using the laser scanner 600. The first three-dimensional coordinates are acquired under a reference coordinate system. The point cloud is a massive collection of points that represent the spatial distribution of the target and the characteristics of the target surface in the same spatial reference system.
S5: according to the coordinate transformation principle, the third three-dimensional coordinates of the at least three observation points 500 in the absolute coordinates are used as a reference, the first three-dimensional coordinates and the point cloud are transformed from the reference coordinate system to the absolute coordinate system, and therefore the second three-dimensional coordinates of the point cloud in the absolute coordinate system are obtained. Since the laser scanner 600 is in the risk area and the coordinate of the reference coordinate system changes with the shield construction, the first three-dimensional coordinate (in the reference coordinate system) of the observation point 500 also changes, the third three-dimensional coordinate (in the absolute coordinate system) of the observation point 500 is used as a reference, the point cloud is transformed from the reference coordinate system to the absolute coordinate system, and the noise points except the risk sub-source point cloud in the absolute coordinate system are deleted. The point cloud of the invention is firstly obtained in a reference coordinate system, and then the point cloud is transformed into an absolute coordinate system based on the association of the reference coordinate system and the absolute coordinate system by the observation point 500. In this way, the point cloud can be compared with the static data of the corresponding risk sub-source in the BIM platform (the static data is established in the absolute coordinate system), so that the coordinate change in the absolute coordinate system can directly form deformation data, so that a comparison result can be formed with the static data; secondly, in different shield tunneling construction stages, the acquisition frequency of the point cloud is set based on spatial data, specifically: the change rate of the settlement displacement of the structure along with the time when the shield penetrates to the structure is larger than that of other construction stages, so that the measurement frequency of the point cloud is improved, the measurement time is shortened, the settlement rule of the structure can be conveniently drawn according to the measurement data, and guidance for adjusting construction parameters such as cutter torque adjustment, tunneling speed adjustment, support increase and the like is provided for field construction.
Preferably, the laser scanner 600 is arranged in such a way that it can scan the entire area of the risk sub-source as well as the observation point 500. For example, as shown in fig. 3, the laser scanners 600 are arranged on six sides of the "L" type risk sub source in a substation manner, each laser scanner 600 is responsible for scanning a part of the risk sub source, and each laser scanner 600 can also scan the observation point 500 at the same time. After the scanning of the risk sub-source and the observation point 500 is completed, the partial point clouds obtained by each laser scanner 600 can be unified to the reference coordinate system by using the observation point 500 as a splicing point, so that the complete point cloud of the risk sub-source can be obtained. Preferably, the processing of the point cloud can be introduced into a point cloud post-processing platform, such as any one of Cylone, polyporks, Realworks, surfey, and geotag. For example, the third three-dimensional coordinate of the observation point 500 in the absolute coordinate system is imported into the point cloud post-processing platform as the first set of data; and importing the first three-dimensional coordinates of the observation point 500 in the reference coordinate system and the point cloud of the risk sub-source into a point cloud post-processing platform as a second group of data. And splicing the two groups of data by using a point cloud splicing function of the point cloud post-processing platform, wherein the observation point 500 is used as a splicing control point during splicing, a coordinate system of the first group of data is used as a spliced reference coordinate system, and the point cloud of the risk sub-source is registered to an absolute coordinate system.
Preferably, at least three criteria points 400 are located in a safe area in a manner that can cover the risk area of the risk sub-source. For example, as shown in FIG. 3, the criterion points 400 are located outside the risk region boundary and arranged at four corners, and can cover the entire risk region of the risk sub-source. According to the principle of coordinate transformation, each observation point 500 is arranged in a perspective view with at least two standard points 400 and at least two laser scanners 600, so that the observation point 500 can associate a reference coordinate system and absolute coordinates. The risk area refers to an influence area on a risk sub-source in the shield construction process. And (4) the shield depth of 1-4 times outside the boundary line of the affected area is a safe area.
Preferably, the system further comprises a health monitoring platform 300. A data interface is provided between the health monitoring platform 300 and the monitoring platform 100, so that the health monitoring platform 300 compares the comparison result with a set safety threshold and can output a corresponding early warning result. Wherein, the health monitoring platform 300 reads the set safety threshold corresponding to the real-time spatial data. For example, health monitoring platform 300 and administration platform 100 may be integrated in one computer. The health monitoring platform 300 can send the early warning result to the collecting APP of the engineering personnel through a wireless protocol or display the early warning result on a large screen of a command center. For example, health monitoring platform 300 is configured as follows: and under the condition that the displacement of the structure is greater than or equal to the set safety threshold of the displacement of the corresponding construction stage, the alarm unit sends out a first alarm signal. And/or the alarm unit sends out a second alarm signal when the change rate of the displacement of the structure is greater than or equal to the set safety threshold of the change rate of the displacement in the corresponding construction stage. For example, when the shield is penetrating below the structure, the monitoring platform 100 reads the maximum settlement displacement and the second displacement change rate corresponding to the second construction stage based on the real-time spatial data acquired by the GIS platform, and uses the maximum settlement displacement and the second displacement change rate as the set safety threshold of the displacement and the displacement change rate of the structure, and if the displacement of the structure measured by the laser measurement party 100 is greater than or equal to the set threshold of the displacement of the corresponding construction stage, the alarm unit sends out a first alarm signal, which may be displayed on a screen of a command center to guide field operation.

This embodiment may be a further improvement and/or a supplement to embodiment 1, and repeated contents are not described again. The preferred embodiments of the present invention are described in whole and/or in part in the context of other embodiments, which can supplement the present embodiment, without resulting in conflict or inconsistency.
Preferably, the ambient real-time environment data comprises spatial location data describing a geographical positional relationship between the risk sub-sources. In a shield tunnel construction project, especially in an urban tunnel construction project, the number of risk sub-sources to be monitored is large, and the distance between the risk sub-sources is generally small. Therefore, in order to enable the command center or the command sub-center to acquire the on-site monitoring data, preferably, the GIS platform includes spatial position data for describing the geographic position relationship between the risk sub-sources for the real-time environmental data around the monitoring platform, and the spatial position data is used for being fused with the deformation data of the risk sub-sources of the BIM sub-module. Therefore, the system can monitor the big data of the risk neutron source in the whole shield construction process in the engineering of constructing the tunnel by one shield. Therefore, the initial three-dimensional space model can be constructed by visually displaying the risk neutron source through the spatial position data and the static data, so that the supervision platform 100 can be used for centralized management and control of the risk neutron source in the shield construction.
