Description

Technical Field

[0001] The present application relates to the field of measurement technology, and in particular to an automatic steering prism and a measuring device. Background Art

[0002] A prism is a common detection element, often used in conjunction with a total station to form a non-contact measurement device for detecting three-dimensional coordinate information at any location in space. In industry, workers attach a prism to the device under test and use the total station to emit a laser signal toward the prism. The difference between the laser signal reflected by the prism and the laser signal emitted by the total station is used to determine the degree of deformation of the workpiece structure.

[0003] In related technologies, when monitoring structural deformation in narrow and long areas like tunnels or in complex spatial scenarios, a single total station cannot meet the monitoring requirements. Two or more total stations are required for joint testing. Each total station has a different orientation and emits laser beams in different directions. However, conventional prisms can only reflect laser beams from a fixed direction and cannot reflect laser beams emitted from different directions by different total stations, making multi-station joint testing inconvenient. Utility Model Content

[0004] Based on this, it is necessary to provide an automatic steering prism and a measuring device to address the problem that the current prism is inconvenient for multi-station joint testing.

[0008] Laser detectors, each of the plurality of outer surfaces being provided with the laser detectors, the outer surface where the laser detectors are located being different from the outer surface where the prisms are located;

[0009] A drive assembly is communicatively connected to the laser detector and is used to drive the polyhedron to rotate according to the detection results of the laser detector. The drive assembly can drive the polyhedron to rotate around a first rotation axis and a second rotation axis respectively, and the second rotation axis is perpendicular to the first rotation axis and both pass through the intersection.

[0010] In one embodiment, the driving assembly includes a controller and a first driving member, and the first driving member and each of the laser detectors are respectively in communication with the controller;

[0011] The controller is used to control the action of the first driving member according to the detection result of the laser detector; the output end of the first driving member is connected to the polyhedron and can drive the polyhedron to rotate around the first rotation axis.

[0012] In one embodiment, the drive assembly includes a second drive member, and the controller is in communication with the second drive member;

[0013] The controller is used to control the action of the second driving member according to the detection result of the laser detector;

[0014] The output end of the second driving member is connected to the first driving member and can drive the first driving member to rotate around the second rotation axis.

[0015] In one embodiment, the automatic steering prism includes a bracket and a connecting shaft, the first driving member is disposed on the bracket, the polyhedron is connected to the output end of the first driving member via the connecting shaft, and the first driving member is capable of driving the connecting shaft to drive the polyhedron to rotate around the first rotation axis;

[0016] The output end of the second driving member is connected to the bracket, and the second driving member can drive the bracket to rotate around the second rotation axis.

[0017] In one embodiment, the support comprises:

[0018] Two support members, the two support members are respectively arranged at intervals on both sides of the polyhedron along the extension direction of the first rotation axis, the two sides of the polyhedron are rotatably connected to the two support members via a corresponding connecting shaft, and the first driving member is connected to any one of the connecting shafts;

[0019] The base is spaced apart on one side of the polyhedron along the extension direction of the second rotation axis, the two ends of the base are respectively connected to the two support members, the base is connected to the second driving member, and can rotate around the second rotation axis under the drive of the second driving member.

[0020] In one embodiment, the automatic steering prism includes a pillar, which is arranged on the side of the base away from the polyhedron along the extension direction of the second rotation axis. A accommodating cavity is provided in the pillar, and the second driving member is provided in the accommodating cavity. An opening is provided on the side of the pillar close to the base, and the output end of the second driving member is connected to the base through the opening.

[0021] In one embodiment, the automatic steering prism includes a mounting base, which is arranged on the side of the pillar away from the polyhedron. The mounting base is provided with at least one mounting hole, and a fastener is passed through the mounting hole. The fastener is used to fix the mounting base on the object to be measured.

[0022] In one embodiment, the automatic steering prism includes a power supply assembly, and the power supply assembly includes a battery pack and a wind turbine generator;

[0023] The battery pack is electrically connected to the driving component and is used to provide the driving component with required electricity. The wind turbine is electrically connected to the battery pack and can charge the battery pack.

[0024] In one embodiment, a plurality of the outer surfaces are connected to each other to form a polyhedron, and the outer contour of each outer surface is a polygon.

[0025] In the automatic steering prism of this embodiment, when the polyhedron is in its initial state, the i-th total station emits a laser beam toward the polyhedron, so that the i-th laser detector among the multiple laser detectors receives the laser beam. The i-th laser detector receives the laser beam and transmits the detection result to the drive assembly. Based on the received data, the drive assembly simultaneously drives the polyhedron to rotate about the first and second rotation axes, so that the polyhedron drives the outer surface of the prism to the position of the outer surface where the i-th laser detector was located in the initial state. At this point, the prism is able to receive the laser beam emitted by the i-th total station and reflect the laser beam back to the i-th total station (in a direction opposite to the emission direction). The i-th total station and the prism can then cooperate to monitor the structural deformation of the object to be measured. The drive assembly then drives the polyhedron to rotate about the first and second rotation axes, returning the polyhedron to its initial state. By sequentially arranging i from 1 to N, where N is the total number of total stations, the above-described method can be used to monitor the structural deformation of the object to be measured in multiple different directions by cooperating with each total station and the prism.

[0026] The present application also proposes a measuring device, comprising the aforementioned automatic steering prism and a plurality of laser transceiver devices, wherein the plurality of laser transceiver devices are respectively located at different positions around the periphery of the automatic steering prism, and each of the laser transceiver devices is capable of emitting a laser beam toward the automatic steering prism and receiving the laser beam reflected by the automatic steering prism.

[0027] In the measuring device of this embodiment, when the polyhedron is in its initial state, the i-th laser transceiver device emits a laser beam toward the polyhedron, so that the i-th laser detector among the multiple laser detectors receives the laser beam. The i-th laser detector receives the laser beam and transmits the detection result to the drive assembly. Based on the received data, the drive assembly simultaneously drives the polyhedron to rotate about the first and second rotation axes, so that the polyhedron drives the outer surface of the prism to move to the position of the outer surface where the i-th laser detector was located in the initial state. At this point, the prism is able to receive the laser beam emitted by the i-th laser transceiver device and reflect the laser beam back to the i-th laser transceiver device (in a direction opposite to the emission direction). The i-th laser transceiver device and the prism can then cooperate to monitor the structural deformation of the object to be measured. The drive assembly then drives the polyhedron to rotate about the first and second rotation axes, restoring the polyhedron to its initial state. Among them, by taking i from 1 to N in sequence, where N is the total number of laser transceiver devices, the above method can be used to monitor the structural deformation of the object to be measured in multiple different directions by cooperating with each laser transceiver and prism in sequence.

[0028] This application also proposes a measurement method, which measures the structural deformation of an object using the above-mentioned measuring device, including the following steps:

[0029] When the polyhedron is in an initial posture, the i-th laser transceiver device transmits a laser beam to the polyhedron so that the i-th laser detector receives the laser beam;

[0030] The driving assembly receives the detection result of the i-th laser detector and controls the polyhedron to rotate to an i-th posture; when the polyhedron is in the i-th posture, the outer surface where the prism is located is located at an i-th position, and the i-th position is the position of the outer surface where the i-th laser detector is located when the polyhedron is in the initial posture;

[0031] Then, the driving component controls the polyhedron to return to the initial posture;

[0032] Wherein, i is 1 to N in sequence, and N is the total number of the laser transceiver devices.

[0033] In the measurement method of this embodiment, when the polyhedron is in an initial state, the i-th laser transceiver device among the multiple laser transceiver devices emits a laser beam to the polyhedron, so that the i-th laser detector among the multiple laser detectors receives the laser beam. The i-th laser detector receives the laser beam and transmits the detection result to the driving component. The driving component drives the polyhedron to rotate around the first rotation axis and the second rotation axis at the same time based on the received data, so that the polyhedron rotates to the i-th posture, thereby driving the outer surface where the prism is located to move to the position of the outer surface where the i-th laser detector is located in the initial posture. At this time, the prism can receive the laser beam emitted by the i-th laser transceiver device and can reflect the laser beam (in the direction opposite to the emission direction) back to the i-th laser transceiver device, and then can monitor the structural deformation of the object to be measured through the cooperation of the i-th laser transceiver device and the prism; then the driving component drives the polyhedron to rotate around the first rotation axis and the second rotation axis, so that the polyhedron returns to its initial posture. Here, by sequentially assuming i as 1 to N, where N is the total number of laser transceiver devices, the above-described method can be used to sequentially coordinate each laser transceiver device with a prism to monitor the structural deformation of the object to be measured in multiple different directions. In summary, the measurement method of this embodiment, by disposing prisms and laser detectors on the outer surface of a polyhedron, and by driving the polyhedron to rotate based on the detection results of the laser detector, allows the prism to reflect the laser beam in any direction, facilitating the joint testing of multiple total stations.

[0056] See also Figures 1 to 3 , Figure 1A schematic structural diagram of an automatic steering prism in one embodiment of the present application is shown. An automatic steering prism 100 provided in one embodiment of the present application includes: a polyhedron 110, a prism 120, a laser detector 130, and a drive assembly 140. The polyhedron 110 includes a plurality of outer surfaces 111 connected to each other, and the normals of the plurality of outer surfaces 111 intersect at an intersection point (not shown) inside the polyhedron 110. The distance from each outer surface 111 to the intersection point is equal, at least one outer surface 111 is provided with a prism 120, and the reflection center of the prism 120 coincides with the intersection point. The plurality of outer surfaces 111 are respectively provided with a laser detector 130, and the outer surface 111 where the laser detector 130 is located is different from the outer surface 111 where the prism 120 is located. The driving component 140 is communicatively connected to the laser detector 130 and is used to drive the polyhedron 110 to rotate according to the detection results of the laser detector 130. The driving component 140 can drive the polyhedron 110 to rotate around the first rotation axis 112 and the second rotation axis 113 respectively. The second rotation axis 113 is perpendicular to the first rotation axis 112 and both pass through the intersection.

[0057] In the automatic steering prism 100 of this embodiment, when the polyhedron 110 is in an initial state, an i-th total station (not shown) emits a laser beam toward the polyhedron 110, so that the i-th laser detector 130 among the plurality of laser detectors 130 receives the laser beam. The i-th laser detector 130 receives the laser beam and transmits the detection result to the drive assembly 140. Based on the received data, the drive assembly 140 simultaneously drives the polyhedron 110 to rotate about the first rotation axis 112 and the second rotation axis 113, so that the polyhedron 110 drives the outer surface 111 on which the prism 120 is located to move to the position of the outer surface 111 where the i-th laser detector 130 is located in the initial state. At this point, prism 120 can receive the laser beam emitted by the i-th total station and reflect the laser beam (in a direction opposite to the emission direction) back to the i-th total station. The i-th total station and prism 120 can then cooperate to monitor the structural deformation of the object to be measured. The drive assembly 140 then drives the polyhedron 110 to rotate about the first rotation axis 112 and the second rotation axis 113, restoring the polyhedron 110 to its initial position. By sequentially assuming i as 1 to N, where N is the total number of total stations, the above-described method can be used to sequentially cooperate with each total station and prism 120 to monitor the structural deformation of the object to be measured in multiple different directions.

[0058] To sum up, the automatic steering prism 100 in this embodiment sets the prism 120 and the laser detector 130 through the outer surface 111 of the polyhedron 110. The driving component 140 drives the polyhedron 110 to rotate according to the detection results of the laser detector 130, so that the prism 120 can reflect the laser beam in any direction, which is convenient for the joint testing of multiple total stations.

[0059] In addition, it should be further explained that since the reflection center of the prism 120 coincides with the intersection point in the polyhedron 110, when the driving assembly 140 drives the polyhedron 110 to rotate around the first rotation axis 112 and the second rotation axis 113, the prism 120, driven by the polyhedron 110, only rotates around the first rotation axis 112 and the second rotation axis 113 relative to its own reflection center, that is, the position of the reflection center of the prism 120 remains unchanged during the posture change of the polyhedron 110. Therefore, when the prism 120 reflects the laser beams emitted by total stations in different directions, each laser beam is reflected at the intersection point in the polyhedron 110 and returns in a direction that coincides with and is opposite to the incident direction, thereby avoiding the deviation in the joint test results of the structural deformation of the object by multiple total stations due to the different reflection centers of the prism 120 for laser beams in different directions, thereby improving the accuracy of the joint test results of multiple total stations.

[0060] Finally, since the normals of the multiple outer surfaces 111 of the polyhedron 110 intersect at an intersection inside the polyhedron 110, and the distance from each outer surface 111 to the intersection is equal, the multiple outer surfaces 111 are circumscribed on the same spherical surface with the intersection as the center of the sphere. Therefore, when the polyhedron 110 rotates around the first rotation axis 112 and the second rotation axis 113, when the outer surface 111 of the prism 120 moves to the position of the outer surface 111 where the i-th laser detector 130 is located at the initial posture, the outer surface 111 where the prism 120 is located will coincide with the outer surface 111 where the i-th laser detector 130 is located at the initial posture.

[0061] See also Figure 1 and Figure 2 In some embodiments, the drive assembly 140 includes a controller 141 and a first drive member 142. The first drive member 142 and each laser detector 130 are respectively communicated with the controller 141. The controller 141 is used to control the action of the first drive member 142 according to the detection results of the laser detector 130. The output end (not shown) of the first drive member 142 is connected to the polyhedron 110 and can drive the polyhedron 110 to rotate around the first rotation axis 112.

[0062] In this embodiment, after receiving the detection result of the laser detector 130, the controller 141 controls the first driving member 142 to operate, and the first driving member 142 drives the polyhedron 110 to rotate around the first rotation axis 112, so that the polyhedron 110 automatically rotates around the first rotation axis 112 with high precision.

[0063] In some embodiments, multiple outer surfaces 111 are connected to each other to form a polyhedron shape, and the outer contour of each outer surface 111 is a common polygon such as a pentagon, a hexagon, or a regular pentagon.

[0064] In some embodiments, the polyhedron 110 includes but is not limited to 4 outer surfaces 111 , 6 outer surfaces 111 , 12 outer surfaces 111 , and 20 outer surfaces 111 .

[0065] In some embodiments, the laser detector 130 may receive a red laser beam having a wavelength greater than or equal to 670 nm.

[0066] In some embodiments, the laser detector 130 may be a common laser receiving device such as a silicon photodiode.

[0067] See also Figure 1 and Figure 2 In some embodiments, the driving assembly 140 includes a second driving member 143, and the controller 141 is communicated with the second driving member 143. The controller 141 is used to control the action of the second driving member 143 according to the detection result of the laser detector 130. The output end of the second driving member 143 is connected to the first driving member 142 and can drive the first driving member 142 to rotate around the second rotation axis 113.

[0068] In this embodiment, by setting the output end of the second driving member 143 to be connected to the first driving member 142, the first driving member 142 drives the polyhedron 110 to automatically rotate around the first rotation axis 112 with high precision. The second driving member 143 can drive the first driving member 142 to rotate around the second rotation axis 113, so that the first driving member 142 drives the polyhedron 110 to automatically rotate around the second rotation axis 113 with high precision, thereby realizing the polyhedron 110 automatically rotating around the first rotation axis 112 and the second rotation axis 113 with high precision at the same time, and finally automatically turning the polyhedron 110 towards the total station that emits the laser beam with high precision.

[0069] In some embodiments, the second driving member 143 can be a common rotary driving device such as a rotary cylinder, a rotary motor, etc.

[0070] See also Figure 1 and Figure 2 In some embodiments, the automatic steering prism 100 includes a bracket 150 and a connecting shaft 160. The first driving member 142 is arranged on the bracket 150. The polyhedron 110 is connected to the output end of the first driving member 142 through the connecting shaft 160. The first driving member 142 can drive the connecting shaft 160 to drive the polyhedron 110 to rotate around the first rotation axis 112. The output end of the second driving member 143 is connected to the bracket 150, and the second driving member 143 can drive the bracket 150 to rotate around the second rotation axis 113.

[0071] In this embodiment, the first driving member 142 is arranged on the bracket 150, and the output end of the second driving member 143 is connected to the bracket 150, so that when the first driving member 142 drives the connecting shaft 160 to drive the polyhedron 110 to rotate around the first rotation axis 112, the second driving member 143 can drive the first driving member 142 to rotate around the second rotation axis 113 with the help of the bracket 150, and then drive the polyhedron 110 connected to the first driving member 142 to rotate around the second rotation axis 113.

[0072] It should be supplemented that the first driving member 142 drives the connecting shaft 160 to rotate around its own central axis, thereby driving the polyhedron 110 to rotate around the first rotation axis 112 . The central axis of the connecting shaft 160 is colinear with the first rotation axis 112 .

[0073] See also Figure 1 and Figure 2 In some embodiments, the bracket 150 includes two support members 151 and a base 152. The two support members 151 are respectively arranged at intervals on both sides of the polyhedron 110 along the extension direction of the first rotation axis 112. The two sides of the polyhedron 110 are rotatably connected to the two support members 151 through a corresponding connecting shaft 160. The first driving member 142 is connected to any connecting shaft 160. The base 152 is arranged at intervals on one side of the polyhedron 110 along the extension direction of the second rotation axis 113. The two ends of the base 152 are respectively connected to the two support members 151. The base 152 is connected to the second driving member 143 and can rotate around the second rotation axis 113 under the drive of the second driving member 143.

[0074] In this embodiment, two support members 151 are respectively arranged at intervals on both sides of the polyhedron 110 along the extension direction of the first rotation axis 112, and the two sides of the polyhedron 110 are respectively rotatably connected to the two support members 151 through a corresponding connecting shaft 160, so that when the first driving member 142 drives the corresponding connecting shaft 160 to drive the polyhedron 110 to rotate, the polyhedron 110 can rotate more smoothly around the first rotation axis 112; by setting the two ends of the base 152 to be connected to the two support members 151 respectively, the base 152 is connected to the second driving member 143, so that the second driving member 143 can rotate around the second rotation axis 113 with the help of the driving base 152, so as to drive the support member 151 connected to the base 152 to rotate around the second rotation axis 113, thereby realizing the rotation of the polyhedron 110 around the second rotation axis 113.

[0075] In some embodiments, two connecting shafts 160 are arranged in a one-to-one correspondence with two support members 151, and each connecting shaft 160 is located between the corresponding support member 151 and the polyhedron 110. Each connecting shaft 160 is connected to the polyhedron 110 at one end and passes through the corresponding support member 151 at the other end, and can rotate around its own central axis relative to the corresponding support member 151.

[0076] See also Figure 1 and Figure 2 In some embodiments, the automatic steering prism 100 includes a pillar 170, which is arranged on a side of the base 152 away from the polyhedron 110 along the extension direction of the second rotation axis. A receiving cavity 171 is provided in the pillar 170, and the second driving member 143 is provided in the receiving cavity 171. An opening is provided on a side of the pillar 170 close to the base 152, and the output end of the second driving member 143 is connected to the base 152 through the opening 172.

[0077] In this embodiment, a support 170 is provided with a receiving cavity 171 in the support 170 , and the second driving member 143 is provided in the receiving cavity 171 , which can protect the second driving member 143 and prevent damage to the second driving member 143 by the external environment.

[0078] In some embodiments, the second driving member 143 can be a common rotary driving device such as a rotary cylinder, a rotary motor, etc.

[0079] See also Figure 1 and Figure 2 In some embodiments, the automatic steering prism 100 includes a mounting base 180, which is arranged on the side of the pillar 170 facing away from the polyhedron 110. The mounting base 180 is provided with at least one mounting hole (not shown), and a fastener 181 is passed through the mounting hole. The fastener 181 is used to fix the mounting base 180 on the object to be measured (not shown).

[0080] In this embodiment, by providing a mounting base 180 and fixing the mounting base 180 to the object to be measured with a fastener 181, the automatic steering prism 100 can be fixed at the test position on the object to be measured, thereby facilitating the total station to emit a laser beam to the automatic steering prism 100 to detect the structural deformation of the test position on the object to be measured.

[0081] In some embodiments, the fasteners 181 may be selected from common connectors such as screws and bolts.

The battery pack 191 is electrically connected to the driving assembly 140 and is used to provide the required power to the driving assembly 140. The wind turbine 192 is electrically connected to the battery pack 191, and the wind turbine 192 can charge the battery pack 191.

[0083] In this embodiment, a battery pack 191 is provided to supply power to the drive assembly 140, so that the controller 141, the first drive member 142 and the second drive member 143 in the drive assembly 140 are put into operation; a wind turbine 192 is provided to charge the battery pack 191. On the one hand, the operation of replacing the battery pack 191 is avoided; on the other hand, when the automatic steering prism 100 is set in a tunnel, it is convenient to generate electricity with the help of wind power passing through the tunnel, thereby avoiding multiple wiring in the tunnel to supply power to the battery pack 191, making it more convenient to charge the battery pack 191.

[0084] It should be further explained that the wind turbine 192 can be replaced by battery power supply, external cables, etc., so that charging the battery pack 191 is more convenient in complex scenarios such as tunnels.

[0085] In some embodiments, the battery pack 191 is electrically connected to the controller 141 , the first driver 142 , and the second driver 143 , and is used to provide the required power to the controller 141 , the first driver 142 , and the second driver 143 .

[0086] One embodiment of the present application provides a measuring device (not shown), including the aforementioned automatic steering prism 100, and a plurality of laser transceiver devices (not shown), wherein the plurality of laser transceiver devices are respectively located at different positions around the automatic steering prism 100, and each laser transceiver device is capable of emitting a laser beam toward the automatic steering prism 100, and receiving a laser beam reflected by the automatic steering prism 100.

[0087] In the measurement device of this embodiment, when polyhedron 110 is in its initial state, the i-th laser transceiver (not shown) emits a laser beam toward polyhedron 110, so that the i-th laser detector 130 among the plurality of laser detectors 130 receives the laser beam. The i-th laser detector 130 receives the laser beam and transmits the detection result to the drive assembly 140. Based on the received data, the drive assembly 140 simultaneously drives the polyhedron 110 to rotate about the first rotation axis 112 and the second rotation axis 113, so that the polyhedron 110 drives the outer surface 111 on which the prism 120 is located to the position of the outer surface 111 where the i-th laser detector 130 is located in the initial state. At this point, prism 120 is able to receive the laser beam emitted by the i-th laser transceiver device and reflect the laser beam (in a direction opposite to the emission direction) back to the i-th laser transceiver device. The i-th laser transceiver device and prism 120 can then cooperate to monitor the structural deformation of the object to be measured. The drive assembly 140 then drives the polyhedron 110 to rotate about the first rotation axis 112 and the second rotation axis 113, restoring the polyhedron 110 to its initial position. By sequentially assuming i as 1 to N, where N is the total number of laser transceivers, the above-described method can be used to sequentially cooperate with each laser transceiver device and prism 120 to monitor the structural deformation of the object to be measured in multiple different directions.

[0088] In some embodiments, the laser transceiver device may be a total station.

[0089] See also Figure 4 , Figure 4 A flow chart of a measurement method in one embodiment of the present application is shown. A measurement method provided in one embodiment of the present application measures the structural deformation of an object using the aforementioned measuring device, including the following steps:

[0090] S300 : When the polyhedron 110 is in the initial posture, the i-th laser transceiver device transmits a laser beam to the polyhedron 110 so that the i-th laser detector 130 receives the laser beam.

[0091] S400: The driving component 140 receives the detection result of the i-th laser detector 130 and controls the polyhedron 110 to rotate to the i-th posture. When the polyhedron 110 is in the i-th posture, the outer surface 111 where the prism 120 is located is located at the i-th position. The i-th position is the position of the outer surface 111 where the i-th laser detector 110 is located when the polyhedron 110 is in the initial posture.

[0092] S600: The driving component 140 is then used to control the polyhedron 110 to return to its initial posture, wherein i is 1 to N in sequence, and N is the total number of laser transceiver devices.

[0093] In the measurement method of this embodiment, when the polyhedron 110 is in the initial state, the i-th laser transceiver device among the multiple laser transceivers transmits a laser beam to the polyhedron 110, so that the i-th laser detector 130 among the multiple laser detectors 130 receives the laser beam, and the i-th laser detector 130 receives the laser beam and transmits the detection result to the driving component 140. The driving component 140 drives the polyhedron 110 to rotate around the first rotation axis 112 and the second rotation axis 113 according to the received data, so that the polyhedron 110 rotates to the i-th posture, thereby driving the prism 120 to rotate to the i-th posture. When the outer surface 111 of the polyhedron 110 moves to the initial posture, the position of the outer surface 111 where the i-th laser detector 130 is located, at this time, the prism 120 can receive the laser beam emitted by the i-th laser transceiver device and can reflect the laser beam (in the direction opposite to the emission direction) back to the i-th laser transceiver device, thereby being able to monitor the structural deformation of the object to be measured through the cooperation of the i-th laser transceiver device and the prism 120; then, the driving component 140 drives the polyhedron 110 to rotate around the first rotation axis 112 and the second rotation axis 113, so that the polyhedron 110 returns to its initial posture. Here, by taking i from 1 to N in sequence, where N is the total number of laser transceivers, the above method can be used to monitor the structural deformation of the object to be measured in multiple different directions through the cooperation of each laser transceiver device and the prism 120.

[0094] To sum up, the measurement method in this embodiment sets a prism 120 and a laser detector 130 on the outer surface 111 of the polyhedron 110, and the driving component 140 drives the polyhedron 110 to rotate according to the detection results of the laser detector 130, so that the prism 120 can reflect the laser beam in any direction, which is convenient for the joint testing of multiple total stations.

[0095] In some embodiments, step S300 is preceded by step S200: when establishing the initial posture of the polyhedron 110, the angular coordinate system (αj, βj) of each laser detector 130, where j is sequentially 1 to M, M is the total number of laser detectors 130, the total number of laser detectors 130 is greater than or equal to the total number of laser transceiver devices, the angular coordinate system (αj, βj) represents the position of the outer surface 111 where the jth laser detector 130 is located when the outer surface 111 where the prism 120 is located moves to the initial posture, and the polyhedron 110 needs to rotate an αj angle around the first rotation axis 112 and a βj angle around the second rotation axis 113.

[0096] In this embodiment, an angular coordinate system (αj, βj) is established for each laser detector 130, where j is sequentially 1 to M, M is the total number of laser detectors 130, and the total number of laser detectors 130 is greater than or equal to the total number of laser transceiver devices, so that when the driving component 140 receives the detection result of the i-th laser detector 130, it can control the polyhedron 110 to rotate to the i-th posture according to the angular coordinate system of the i-th laser detector 130, and then drive the outer surface 111 where the prism 120 is located to move to the position of the outer surface 111 where the j-th laser detector 130 is located when the initial posture.

[0097] It should be supplemented that the i-th laser detector 130 refers to any laser detector 130 that receives the laser beam emitted by the i-th laser transceiver device toward the center of the polyhedron 110 .

[0098] In some embodiments, step S200 includes step S100 : setting an automatic steering prism 100 , and arranging a plurality of laser transceiver devices at different positions of the automatic steering prism 100 .

[0099] In some embodiments, after S400 and before S600, step S500 is also included: the laser transceiver receives the laser beam emitted by itself to the polyhedron 110, measures the orientation and distance of the center of the polyhedron 110 relative to itself, and transmits the detection data to a remote control center (not shown).
