Description

Technical Field

[0001] The invention relates to the technical field of measuring equipment, and in particular to a project cost measuring equipment. Background Art

[0002] With the rapid development of bridge engineering, the quality of bridge piers, as an important part of bridge structure, is directly related to the overall safety and stability of bridges. Especially for bridge piers used in water environments such as rivers and oceans, their surfaces are exposed to the influence of water flow and tides for a long time, and are easily eroded by river and sea water. There may even be marine organisms (such as shellfish and algae) attached to the surface of the bridge piers, causing the surface of the bridge piers to gradually corrode or deform irregularly. Therefore, irregular detection of the distance between two adjacent bridge piers to judge the quality of the bridge piers has become an indispensable task in bridge safety monitoring.

[0003] Traditionally, laser rangefinders are widely used to detect the distance between bridge piers due to their advantages such as simple operation, high measurement accuracy, and fast response speed. However, the working principle of laser rangefinders relies on the emission and reflection of laser beams. When the surface of bridge piers is smooth and flat, relatively accurate measurement results can be obtained. However, when the surface of bridge piers becomes rough due to erosion by river water and sea water, or when marine organisms are attached to the surface of bridge piers, the reflection performance of the laser beam will be significantly affected, resulting in a decrease in measurement accuracy. Specifically, corrosion on the surface of bridge piers and attachment of marine organisms will cause scattering and absorption of laser beams, and part of the reflected signal will be weakened or lost. The rangefinder cannot correctly identify the true surface position of the bridge piers, thus affecting the accuracy of the measurement results. Summary of the invention

[0004] The invention provides an engineering cost measurement device to solve the problem that the existing measurement device cannot accurately measure the distance between two bridge piers.

[0005] A construction cost measurement device of the present invention adopts the following technical solution:

[0006] A construction cost measurement device comprises a transmitter, a positioning module and an adjustment module.

[0007] The positioning module is used to position the transmitter on the first pier. The transmitter can emit laser to any position of the second pier. The laser can be reflected by the second pier and return to the transmitter again. The transmitter can analyze the detection distance between the first pier and the second pier based on the received laser. The adjustment module can adjust the position of the transmitter on the first pier. The adjustment module can also adjust the angle between the laser emitted by the transmitter and the horizontal plane.

[0008] Furthermore, it also includes an analysis module and a repair module. The analysis module can obtain a reference distance between the first pier and the second pier based on the construction data of the pier. The analysis module can also analyze the detection distance based on the reference distance. If the analysis result belongs to the first target type, the repair module can execute a first repair procedure on the surface of the second pier. The repair module can also execute a second repair procedure on the transmitter.

[0009] Further, the adjustment module can adjust the position of the transmitter on the first pier according to the first adjustment logic when the result of the analysis by the analysis module belongs to the first target type.

[0010] Furthermore, the first adjustment logic includes:

[0011] Taking the position where the transmitter first emits the laser as a reference, a cross coordinate system is established on the first bridge pier;

[0012] The transmitter is regulated to fire multiple lasers in each quadrant.

[0013] Furthermore, based on the detection distance obtained after the position of the transmitter on the first bridge pier is adjusted, the analysis module can formulate a repair range of the first repair program on the surface of the second bridge pier.

[0014] Furthermore, the first repair procedure includes:

[0015] If the reference distance is greater than the detection distance, a cleaning procedure is performed on the repaired area on the surface of the second pier;

[0016] If the reference distance is smaller than the detection distance, a patching procedure is performed on the repair range of the second pier surface.

[0017] Further, the cleaning procedure includes:

[0018] Based on the architectural data of the bridge piers, initial roughness of the surfaces of the first bridge pier and the second bridge pier is obtained;

[0019] obtaining the actual roughness of the surface of the first pier;

[0020] Predicting a first roughness that the surface of the second bridge pier should have based on the actual roughness of the surface of the first bridge pier and the initial roughness of the surface of the first bridge pier;

[0021] The actual roughness of the surface of the second pier is cleaned to the first roughness.

[0022] Further, the fixes include:

[0023] Based on the architectural data of the bridge piers, initial roughness of the surfaces of the first bridge pier and the second bridge pier is obtained;

[0024] obtaining the actual roughness of the surface of the first pier;

[0025] Based on the actual roughness of the first bridge pier surface and the initial roughness of the first bridge pier surface, predicting the second roughness that the second bridge pier surface should have;

[0026] The actual roughness of the second pier surface is repaired to the second roughness.

[0027] Further, the repair module can also execute a second repair procedure on the transmitter, and the second repair procedure includes:

[0028] If the reference distance is greater than or less than the detection distance, increase the power of the laser emitted by the transmitter.

[0029] Furthermore, the second repair procedure also includes:

[0030] Get the transmission power of the laser emitted by the transmitter;

[0031] If the analysis result of the analysis module on the reference distance and the detection distance belongs to the first target type, the power of the laser received by the transmitter is obtained;

[0032] Based on the transmitted power and the received power, it is proposed to increase the amount of power of the laser emitted by the transmitter.

[0033] The beneficial effects of the present invention are as follows: the present invention provides an engineering cost measurement device, which includes a transmitter, a positioning module and an adjustment module. When measuring the distance between bridge piers, the positioning module is used to position the transmitter on the first bridge pier. The transmitter can emit a laser to any position of the second bridge pier. The laser is reflected by the second bridge pier and returns to the transmitter again. The transmitter can analyze the detection distance between the first bridge pier and the second bridge pier based on the received laser. In order to improve the accuracy of the detection distance between the first bridge pier and the second bridge pier, the adjustment module adjusts the position of the transmitter on the first bridge pier, that is, replaces the detection point. The adjustment module can also adjust the angle between the laser emitted by the transmitter and the horizontal plane to prevent the situation where there is an angle between the laser and the horizontal plane, thereby improving the accuracy of the detection distance between the first bridge pier and the second bridge pier.

[0034] Furthermore, the reference distance between the first pier and the second pier is obtained through the analysis module. Since the first pier is the location where the transmitter is set, the condition of the surface of the first pier can be directly observed. There is a distance difference between the second pier and the first pier, and direct observation cannot accurately determine the condition of the surface of the second pier. At this time, the reference distance and the detection distance are analyzed by the analysis module. If the reference distance and the detection distance meet the first target type, there may be defects on the surface of the second pier. At this time, the first repair procedure is executed on the surface of the second pier through the repair module. At the same time, the repair module can also execute the second repair procedure on the transmitter. After the repair module repairs the surface of the second pier and the transmitter, the accuracy of distance detection between the first pier and the second pier can be improved in subsequent measurements.

In addition, the mutual coupling or direct coupling or communication connection shown or discussed can be an indirect coupling or communication connection through some interfaces, devices or units, or it can be an electrical, mechanical or other form of connection.

[0041] like Figure 1 As shown, an embodiment of the present invention provides a construction cost measurement device, which includes a transmitter 110, a positioning module and an adjustment module.

[0042] The transmitter 110 can emit laser light, and the laser light can be irradiated in any direction. The power of the laser light emitted by the transmitter 110 can be adjusted, thereby increasing the applicable range of the transmitter 110 .

[0043] The positioning module is used to position the transmitter 110 on the first bridge pier. The transmitter 110 can emit laser to any position of the second bridge pier. The laser can be reflected by the second bridge pier and return to the transmitter 110 again. The transmitter 110 can analyze the detection distance between the first bridge pier and the second bridge pier based on the received laser.

[0044] Specifically, the transmitter 110 is positioned on the first pier through the positioning module. When the transmitter 110 is installed on the first pier, the transmitter 110 can emit a laser to the second pier, wherein the first pier and the second pier are different piers on the same bridge. When measuring the distance between the first pier and the second pier, the transmitter 110 is positioned on the first pier. Further, the positioning module includes a positioning plate 130, and the positioning plate 130 can be fixedly installed on the first pier. The transmitter 110 is installed on the positioning plate 130. By installing the positioning plate 130, the transmitter 110 can be positioned on the first pier, and then the transmitter 110 is used to emit a laser to the second pier. Further, the first pier is a pier that is convenient for observing and installing the transmitter 110. When installing the transmitter 110, ensure that the surface of the first pier is flat. When the transmitter 110 transmits a laser to the second pier, the laser can be reflected by the second pier and return to the transmitter 110 again. The transmitter 110 can analyze the detection distance between the first pier and the second pier based on the received laser. The staff can judge the status of the second pier based on the detection distance between the first pier and the second pier, such as whether the surface of the second pier is eroded by water flow or impurities are attached to the surface of the second pier.

[0045] The adjustment module can adjust the position of the transmitter 110 on the first bridge pier, and the adjustment module can also adjust the angle between the laser emitted by the transmitter 110 and the horizontal plane.

[0046] Specifically, when detecting the distance between the first bridge pier and the second bridge pier, the position of the transmitter 110 on the first bridge pier is adjusted by the adjustment module, and the transmitter 110 can obtain multiple sets of detection distances. After recording and analyzing the multiple sets of detection distances, the state of the second bridge pier can be accurately obtained, or the detection distance between the second bridge pier and the first bridge pier can be accurately obtained. The adjustment module can also adjust the angle between the laser emitted by the transmitter 110 and the horizontal plane. When the transmitter 110 emits a laser to the second bridge pier, the adjustment module adjusts the angle between the laser emitted by the transmitter 110 and the horizontal plane to zero degrees. It can be understood that the adjustment module ensures that the laser emitted by the transmitter 110 is parallel to the horizontal plane, thereby improving the accuracy of the detection distance between the first bridge pier and the second bridge pier. Further, the adjustment module includes a level meter, which is arranged on the transmitter 110. By adjusting the position of the transmitter 110 on the first bridge pier, it is ensured that the laser emitted by the transmitter 110 is in a horizontal state. Furthermore, the adjustment module further includes a control frame 120 , which can be installed on the positioning plate 130 . Under the action of the control frame 120 , the transmitter 110 can slide arbitrarily on the positioning plate 130 .

[0047] The present invention provides an engineering cost measurement device. When measuring the distance between bridge piers, a positioning module is used to position a transmitter 110 on a first bridge pier. The transmitter 110 can emit a laser to any position of a second bridge pier. The laser is reflected by the second bridge pier and returns to the transmitter 110 again. The transmitter 110 can analyze the detection distance between the first bridge pier and the second bridge pier based on the received laser. To improve the accuracy of the detection distance between the first bridge pier and the second bridge pier, an adjustment module adjusts the position of the transmitter 110 on the first bridge pier, that is, replaces the detection point. The adjustment module can also adjust the angle between the laser emitted by the transmitter 110 and the horizontal plane to prevent the situation where there is an angle between the laser and the horizontal plane, thereby improving the accuracy of the detection distance between the first bridge pier and the second bridge pier.

[0048] In one embodiment, a construction cost measurement device also includes an analysis module and a repair module. The analysis module can obtain a reference distance between a first pier and a second pier based on the construction data of the piers. The analysis module can also analyze the detection distance based on the reference distance. If the analysis result belongs to the first target type, the repair module can execute a first repair procedure on the surface of the second pier. The repair module can also execute a second repair procedure on the transmitter 110.

[0049] Specifically, the construction data of the pier includes construction drawings. When building a bridge, the construction is based on the construction drawings. The reference distance between the first pier and the second pier is marked on the construction drawings. When the first pier and the second pier do not have surface erosion, impurity adhesion, etc., the detection distance between the first pier and the second pier should be equal to the reference distance. When the transmitter 110 acquires the detection distance between the first pier and the second pier multiple times, the analysis module can analyze the detection distance based on the reference distance. If the analysis result belongs to the first target type, the repair module can perform a first repair procedure on the surface of the second pier, and the repair module can also perform a second repair procedure on the transmitter 110. Specifically, the first target type is that the detection distance is not equal to the reference distance. When the analysis result belongs to the first target type, it proves that the second pier may have surface erosion, impurity adhesion, etc. At this time, the repair module can perform the first repair procedure on the surface of the second pier to ensure that there is no erosion and impurity adhesion on the surface of the repaired second pier, so as to facilitate the subsequent measurement of the accurate detection distance between the first pier and the second pier. At the same time, the repair module can also execute a second repair program on the transmitter 110. After the second repair program adjusts the transmitter 110, it ensures that the laser emitted by the transmitter 110 can be received by the transmitter 110 again after being reflected by the surface of the second bridge pier, thereby preventing the situation where the laser emitted by the transmitter 110 cannot be received by the transmitter 110 again after being reflected by the surface of the second bridge pier.

[0050] In one embodiment, the adjustment module can adjust the position of the transmitter 110 on the first pier according to the first adjustment logic when the result of the analysis by the analysis module belongs to the first target type.

[0051] Specifically, when the transmitter 110 is used for the first time to obtain the detection distance between the first pier and the second pier, after the analysis module analyzes the detection distance based on the reference distance, if the analysis result belongs to the first target type, it proves that the second pier may have surface erosion, impurity adhesion, etc. At this time, in order to clarify the specific condition of the surface of the second pier, the adjustment module adjusts the position of the transmitter 110 on the first pier according to the first adjustment logic. After the position of the transmitter 110 on the first pier is adjusted, the detection distance is analyzed multiple times to clarify the specific condition of the surface of the second pier, so as to facilitate the repair module to execute the first repair procedure on the second pier.

[0052] In one embodiment, the first adjustment logic includes: establishing a cross coordinate system on the first bridge pier based on the position where the emitter 110 emits the laser for the first time; and regulating the emitter 110 to emit the laser multiple times in each quadrant.

[0053] Specifically, when the transmitter 110 is used for the first time to obtain the detection distance between the first bridge pier and the second bridge pier, after the analysis module analyzes the detection distance based on the reference distance, if the analysis result belongs to the first target type, it proves that the second bridge pier may have surface erosion, impurity adhesion, etc. At this time, a cross coordinate system is established on the first bridge pier based on the position where the transmitter 110 first emits the laser, wherein the reference position is the zero point of the cross coordinate system, and the surface of the first bridge pier is divided into four quadrants, namely the first quadrant, the second quadrant, the third quadrant, and the fourth quadrant. The transmitter 110 is regulated to emit multiple lasers in each quadrant, and at the same time, the transmitter 110 is regulated to emit multiple lasers on the coordinate axis to ensure that after the transmitter 110 is used multiple times to obtain the detection distance, the specific surface condition of the second bridge pier can be measured.

[0054] In one embodiment, based on the detection distance obtained after the position of the transmitter 110 on the first bridge pier is adjusted, the analysis module can formulate a repair range of the first repair procedure on the surface of the second bridge pier.

[0055] Specifically, after using the transmitter 110 for multiple times to obtain the detection distance, there are some detection distances that are equal to the reference distance, and some detection distances that are not equal to the reference distance. The analysis module can analyze the detection distance and the reference distance obtained each time, and mark the position where the analysis result belongs to the first target type. By analyzing multiple marked points, the range of water erosion or impurity attachment on the surface of the second pier is determined, thereby clarifying the range of the second pier surface that needs to be repaired by the first repair procedure, and further improving the speed of repairing the second pier surface.

[0056] In one embodiment, the first repair procedure includes: if the reference distance is greater than the detection distance, then executing a cleaning procedure on the repair range of the second pier surface; if the reference distance is less than the detection distance, then executing a patching procedure on the repair range of the second pier surface.

[0057] Specifically, when the first target type is that the detection distance is not equal to the reference distance, the first target type is that the detection distance is greater than the reference distance, or the first target type is that the detection distance is less than the reference distance. Based on the difference between the detection distance and the reference distance, the repair range of the second pier surface can be defined as depression and protrusion. Further, when the reference distance is greater than the detection distance, it indicates that there is a protrusion on the second pier surface, and when the reference distance is less than the detection distance, it indicates that there is a depression on the second pier surface. When there is a protrusion on the surface of the second pier, a cleaning procedure is performed on the second pier surface, and when there is a depression on the second pier surface, a repair procedure is performed on the second pier surface.

[0058] In one of the embodiments, if the second pier undergoes irregular settlement, the measured distance between the first pier and the second pier obtained by the transmitter 110 is also different from the reference distance. At this time, the analysis result of the analysis module belongs to the first target type. The adjustment module adjusts the position of the transmitter 110 on the first pier according to the first adjustment logic. After multiple measurements, the detection distance between the first pier and the second pier changes regularly in the vertical direction, which proves that the second pier has undergone irregular settlement. At this time, the analysis module can analyze the settlement mode of the second pier through the detection distance obtained multiple times by the transmitter 110. The analysis module can transmit the analysis results to the staff, and the staff can carry out targeted processing on the second pier.

[0059] In one embodiment, the cleaning procedure includes: obtaining the initial roughness of the surfaces of the first pier and the second pier based on the construction data of the pier; obtaining the actual roughness of the surface of the first pier; predicting the first roughness that the surface of the second pier should have based on the actual roughness of the surface of the first pier and the initial roughness of the surface of the first pier; and cleaning the actual roughness of the surface of the second pier to the first roughness.

[0060] Specifically, when building a bridge, construction is performed based on architectural drawings, and the architectural drawings indicate requirements for the initial surface roughness of the first pier and the second pier. Then, the initial surface roughness of the first pier and the second pier is obtained by reading the architectural drawings.

[0061] Furthermore, the actual roughness of the surface of the first pier is obtained. Specifically, the actual roughness of the surface of the first pier is obtained by using a stylus method. The stylus method is to use a probe with a needle tip to slowly move across the surface of the first pier. When the needle tip of the probe moves with the ups and downs of the surface of the first pier, a displacement sensor can be used to accurately detect the vertical displacement change of the needle tip, thereby obtaining the actual roughness of the surface of the first pier.

[0062] Further, after the first pier and the second pier are constructed, the roughness of the surface of the first pier may change with the passage of time. The natural environment in which the first pier and the second pier are located remains the same, and the roughness of the surface of the second pier changes at the same time. Based on the actual roughness of the surface of the first pier and the initial roughness of the surface of the first pier, the change amount of the surface roughness of the first pier within the preset time period can be determined, wherein the preset time period is the time interval between the detection and the construction. According to the actual roughness of the surface of the first pier, the initial roughness of the surface of the first pier and the length of the preset time period, a related coordinate system can be established. The roughness loss amount of the surface of the first pier increases with the increase of the preset time period, and when there is no interference of the external environment on the second pier, the surface roughness of the second pier should be consistent with the surface roughness of the first pier, then the actual roughness of the surface of the second pier should be consistent with the actual roughness of the surface of the first pier in an ideal state. At this time, the first roughness of the surface of the second pier is predicted, and the first roughness of the surface of the second pier is predicted to be equal to the actual roughness of the surface of the first pier, wherein the first roughness is the actual roughness of the surface of the second pier.

[0063] Furthermore, when cleaning the surface of the second pier, impurities attached to the surface of the second pier will affect the roughness of the surface of the second pier. When the actual roughness of the surface of the second pier is cleaned to the first roughness, the accuracy of the detected distance obtained can be improved when the transmitter 110 is used to obtain the detected distance between the first pier and the second pier. Furthermore, a high-pressure water gun can be used to clean the impurities on the surface of the second pier.

[0064] In one embodiment, the repair procedure includes: obtaining the initial roughness of the surfaces of the first pier and the second pier based on the construction data of the pier; obtaining the actual roughness of the surface of the first pier; predicting the second roughness that the surface of the second pier should have based on the actual roughness of the surface of the first pier and the initial roughness of the surface of the first pier; and repairing the actual roughness of the surface of the second pier to the second roughness.

[0065] Specifically, when building a bridge, construction is performed based on architectural drawings, and the architectural drawings indicate requirements for the initial surface roughness of the first pier and the second pier. Then, the initial surface roughness of the first pier and the second pier is obtained by reading the architectural drawings.

[0066] Furthermore, the actual roughness of the surface of the first pier is obtained. Specifically, the actual roughness of the surface of the first pier is obtained by using a stylus method. The stylus method is to use a probe with a needle tip to slowly move across the surface of the first pier. When the needle tip of the probe moves with the ups and downs of the surface of the first pier, a displacement sensor can be used to accurately detect the vertical displacement change of the needle tip, thereby obtaining the actual roughness of the surface of the first pier.

[0067] Further, after the first pier and the second pier are constructed, the roughness of the surface of the first pier may change with the passage of time. The natural environment in which the first pier and the second pier are located remains the same, and the roughness of the surface of the second pier changes at the same time. Based on the actual roughness of the surface of the first pier and the initial roughness of the surface of the first pier, the change amount of the surface roughness of the first pier within the preset time period can be determined, wherein the preset time period is the time interval between the detection and the construction. According to the actual roughness of the surface of the first pier, the initial roughness of the surface of the first pier and the length of the preset time period, a related coordinate system can be established. The roughness loss amount of the surface of the first pier increases with the increase of the preset time period, and when there is no interference from the external environment on the second pier, the surface roughness of the second pier should be consistent with the surface roughness of the first pier, then the actual roughness of the surface of the second pier should be consistent with the actual roughness of the surface of the first pier in an ideal state. At this time, the second roughness of the surface of the second pier is predicted, and the second roughness of the surface of the second pier is predicted to be equal to the actual roughness of the surface of the first pier, wherein the second roughness is the actual roughness of the surface of the second pier.

[0068] Furthermore, when the surface of the second pier is repaired, after the depression on the surface of the second pier is repaired, the newly added material will affect the roughness of the surface of the second pier, so that the actual roughness of the surface of the second pier is less than the second roughness. During the repair process, the actual roughness of the surface of the second pier is adjusted to be equal to the second roughness by grinding. When the transmitter 110 is subsequently used to obtain the detection distance between the first pier and the second pier, the accuracy of the obtained detection distance can be improved.

[0069] In one embodiment, the repair module can also execute a second repair procedure on the transmitter 110 , and the second repair procedure includes: if the reference distance is greater than or less than the detection distance, increasing the power of the laser emitted by the transmitter 110 .

[0070] Specifically, when the reference distance is greater than or less than the detection distance, there are depressions or protrusions on the surface of the second pier. At this time, the roughness of the surface of the second pier will change. If the power of the laser emitted by the transmitter 110 is not adjusted, the laser emitted by the transmitter 110 may not be received by the transmitter 110 after being reflected by the surface of the second pier. At this time, the power of the laser emitted by the transmitter 110 is increased to ensure that the laser emitted by the transmitter 110 is received again by the transmitter 110 after being reflected by the surface of the second pier.

[0071] In one embodiment, the second repair procedure also includes: obtaining the emission power of the laser emitted by the transmitter 110; if the analysis result of the analysis module on the reference distance and the detection distance belongs to the first target type, then obtaining the power of the laser received by the transmitter 110; based on the emission power and the receiving power, it is planned to increase the amount of power of the laser emitted by the transmitter 110.

[0072] Specifically, the emission power of the laser emitted by the transmitter 110 is obtained, wherein the emission power of the laser emitted by the transmitter 110 is read by a power meter, wherein the power meter is integrated on the transmitter 110, and the real-time power of the laser emitted by the transmitter 110 can be displayed on the power meter.

[0073] Furthermore, the laser emitted by the transmitter 110 can be received by the transmitter 110 again after being reflected by the second bridge pier, wherein the power meter on the transmitter 110 can detect the power of the laser received by the transmitter 110. If the analysis result of the reference distance and the detection distance by the analysis module belongs to the first target type, the power of the laser received by the transmitter 110 is obtained, wherein the power of the laser received by the transmitter 110 is read by the power meter.

[0074] Furthermore, after the transmitter 110 emits the laser, the laser moves for a period of time and reaches the surface of the second bridge pier. The laser will be reflected on the surface of the second bridge pier. During the laser reflection process, the power of the laser will be lost. The emitted laser will run for a period of time again before being received by the transmitter 110. In addition, during the operation of the laser, the laser will contact with particles in the air, which will also cause the power of the laser to decrease, resulting in a difference between the emission power and the reception power of the laser. Based on the emission power and the reception power, it can be clearly understood how much power loss occurred after the transmitter 110 irradiated the surface of the second bridge pier. After multiple uses of the transmitter 110 to emit the laser to the second bridge pier, when there are different conditions on the surface of the second bridge pier, when the transmitter 110 emits the laser at a fixed emission power, the laser emitted by the transmitter 110 is reflected by the surface of the second bridge pier, and the power amount received by the transmitter 110 again will change. It is easy to understand that when there are different conditions on the surface of the second bridge pier, the difference between the emission power and the reception power of the transmitter 110 is different.

[0075] Furthermore, if the power of the laser emitted by the transmitter 110 is increased without limit without considering the loss of the laser, it is easy to accelerate the aging and loss of the relevant components inside the transmitter 110, thereby reducing the overall service life of the transmitter 110. When increasing the emission power of the transmitter 110, it is necessary to ensure that the laser emitted by the transmitter 110 can be received by the transmitter 110 again after being reflected by the second bridge pier. Therefore, when the amount of increasing the power of the laser emitted by the transmitter 110 is proposed, the emission power of the transmitter 110 is slowly adjusted until the laser emitted by the transmitter 110 is just received by the transmitter 110 again after being reflected by the surface of the second bridge pier, thereby preventing the situation where the laser emitted by the transmitter 110 cannot be received by the transmitter 110 again after being reflected by the surface of the second bridge pier. At the same time, it is avoided that the laser emission power of the transmitter 110 is increased without limit, thereby improving the service life of the transmitter 110.

[0076] The technical features of the above embodiments may be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
