This device can calculate the distance between the target object and the rangefinder by emitting a laser beam and receiving the reflected signal.

[0035] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0036] In one embodiment, as shown in FIG. 1 , a multifunctional intelligent laser rangefinder is provided, including: a laser rangefinder module 101 and an intelligent computing module 102 .

[0037] Among them, the intelligent calculation module 102 is a module used by the multifunctional intelligent laser rangefinder to realize the intelligent calculation function. After obtaining the measured value, the clearance distance between the tree and the transmission line can be calculated through the module. The clearance distance acquisition request is a request initiated by the user to calculate the clearance distance between a certain tree, that is, the target tree, and a certain transmission line, that is, the target transmission line. The request scene mode refers to the scene corresponding to the triggered clearance distance acquisition request. In this embodiment, the acquisition of the clearance distance can include a variety of scenes, for example, it can include: the scene of obtaining the clearance distance of wind-deflected trees, the scene of obtaining the clearance distance of wind-deflected trees on the slope, the scene of obtaining the distance of fallen trees on the slope, etc. Specifically, when the user needs to obtain the clearance distance between the target tree and the target transmission line, the clearance distance acquisition request can be initiated by inputting the request scene mode through the multifunctional intelligent laser rangefinder. At this time, the multifunctional intelligent laser rangefinder can respond to the above clearance distance acquisition request to obtain the request scene mode matching the clearance distance acquisition request.

[0038] The laser ranging module 101 is a module used by the multifunctional intelligent laser rangefinder to realize the laser ranging function. When obtaining the clearance distance between the target tree and the target power transmission line, the laser ranging module 101 needs to be used to measure the corresponding distance data to complete the calculation of the clearance distance. The distance data to be measured can be obtained according to the requested scene mode, and at least include the following parts: the horizontal distance between the placement position of the multifunctional intelligent laser rangefinder and the target tree, that is, the first horizontal distance, the horizontal distance between the placement position of the multifunctional intelligent laser rangefinder and the target power transmission line, that is, the second horizontal distance, the line height of the target power transmission line, and the height information of the target tree, for example, the tree height, tree base height and tree top height of the target tree, etc.

[0039] After the laser ranging module 101 completes the distance data measurement required for the clearance distance, the intelligent calculation module 102 can further use the above distance data to calculate the clearance distance corresponding to the requested scene mode. Specifically, the intelligent calculation module 102 can pre-store a variety of calculation formulas for calculating the clearance distance, and each calculation formula is used to calculate the clearance distance of different scene modes. The target clearance distance calculation formula refers to the clearance distance calculation formula that matches the requested scene mode corresponding to the clearance distance acquisition request.

[0040] For example, the three scenarios of obtaining the clearance distance of wind-biased trees, obtaining the clearance distance of wind-biased trees on slopes, and obtaining the distance of fallen trees on slopes with wind-biased trees correspond to different clearance distance calculation formulas. When the user selects the clearance distance of wind-biased trees as the request scenario mode, the intelligent computing module 102 can use the clearance distance calculation formula corresponding to the request scenario mode as the target clearance distance calculation formula, thereby using the target clearance distance calculation formula, and the first horizontal distance, the second horizontal distance, the conductor height, and the height information measured by the laser ranging module 101 to calculate the clearance distance between the target tree and the target power transmission line. For example, the intelligent computing module 102 can substitute the first horizontal distance, the second horizontal distance, the conductor height, and the height information measured by the laser ranging module 101 into the target clearance distance calculation formula to obtain the clearance distance between the target tree and the target power transmission line.

[0041] The multifunctional intelligent laser rangefinder comprises: a laser rangefinder module 101 and an intelligent calculation module 102; wherein: the intelligent calculation module 102 is used to respond to a clearance distance acquisition request triggered by a user and obtain a request scene mode matching the clearance distance acquisition request; the clearance distance acquisition request is used to obtain the clearance distance between the target tree and the target power transmission line; the laser rangefinder module 101 is used to measure the first horizontal distance between the multifunctional intelligent laser rangefinder and the target tree, the second horizontal distance between the multifunctional intelligent laser rangefinder and the target power transmission line, the wire height of the target power transmission line and the height information of the target tree; the intelligent calculation module 102 is also used to obtain a target clearance distance calculation formula matching the request scene mode from a plurality of clearance distance calculation formulas stored in advance; and the clearance distance between the target tree and the target power transmission line matching the request scene mode is obtained by using the target clearance distance calculation formula, the first horizontal distance, the second horizontal distance, the wire height and the height information. The multifunctional intelligent laser rangefinder provided in the present application can obtain the scene mode corresponding to the clearance distance acquisition request through the intelligent computing module 102 when receiving the clearance distance acquisition request triggered by the user, and can obtain the first horizontal distance between the multifunctional intelligent laser rangefinder and the target tree, the second horizontal distance between the multifunctional intelligent laser rangefinder and the target transmission line, the line height of the target transmission line and the height information of the target tree through the laser ranging module 101, so that the clearance distance between the target tree and the target transmission line that matches the requested scene mode is obtained by the intelligent computing module 102 using the target clearance distance calculation formula that matches the requested scene mode, as well as the above-mentioned first horizontal distance, second horizontal distance, line height and height information. In this way, the clearance distance between the target tree and the transmission line can be directly output by the multifunctional intelligent laser rangefinder without the need for the user to manually calculate the clearance distance based on the distance measurement result, thereby improving the accuracy of obtaining the clearance distance.

[0042] In one embodiment, the request scene mode includes: a first request scene mode for measuring the clearance distance of wind-biased trees on horizontal land; the height information of the target tree includes: the tree height of the target tree; the intelligent computing module 102 is further used to use the first clearance distance calculation formula as the target clearance distance calculation formula when the request scene mode is the first request scene mode; obtain the clearance distance matching the first request scene mode through the first clearance distance calculation formula, the first horizontal distance, the second horizontal distance, the wire height and the tree height; the first clearance distance calculation formula is: ;in, Indicates the clearance distance that matches the first requested scene mode, Indicates the second horizontal distance, Indicates the first horizontal distance, Indicates the height of the wire, Indicates the height of the tree.

[0043] In this embodiment, the request scene mode matched with the clearance distance acquisition request may be the first request scene mode, which can be used to calculate the clearance distance of wind-biased trees on horizontal land, that is, to calculate the clearance distance of wind-biased trees on horizontal land, which refers to the distance between the tree and the power transmission line or power equipment when the tree is outside the wire and is not in the same vertical plane as the wire. This distance needs to meet the requirements of safety regulations to prevent the tree from falling in strong winds or the wind-biased trees from meeting the safety distance requirements of nearby power facilities, resulting in discharge accidents.

[0044] The first clearance distance calculation formula is used to calculate the clearance distance of wind-biased trees on horizontal land. This calculation formula can be calculated using the following calculation formula:

[0045]

[0046] in, represents the clearance distance matched by the first requested scene mode, i.e., the wind-biased tree clearance distance between the target tree and the target transmission line on the horizontal land, Indicates the second horizontal distance, Indicates the first horizontal distance, Indicates the height of the wire, Indicates the height of the tree.

[0047] In this embodiment, when the requested scene mode is the first requested scene mode, the calculation formula used may be: ,in, Indicates the clearance distance that matches the first requested scene mode, Indicates the second horizontal distance, Indicates the first horizontal distance, Indicates the height of the wire, Represents the tree height. Through this formula, the wind-induced tree clearance distance calculation between the target tree and the target transmission line on the horizontal land is realized, thereby improving the accuracy of the wind-induced tree clearance distance calculation between the target tree and the target transmission line on the horizontal land.

[0048] In one embodiment, the request scene mode includes: a second request scene mode for measuring the clearance distance of a wind-bent tree falling on horizontal land; the height information of the target tree includes: the tree height of the target tree; the intelligent calculation module is further used to use the second clearance distance calculation formula as the target clearance distance calculation formula when the request scene mode is the second request scene mode; obtain the clearance distance matching the second request scene mode through the second clearance distance calculation formula, the first horizontal distance, the second horizontal distance, the wire height and the tree height; the second clearance distance calculation formula is: ;in, Indicates the clearance distance that matches the second requested scene mode, Indicates the second horizontal distance, Indicates the first horizontal distance, Indicates the height of the wire, Indicates the height of the tree.

[0049] In this embodiment, the request scene mode that matches the clearance distance acquisition request may be the second request scene mode, which can be used to calculate the distance of wind-deflected trees falling on horizontal land, that is, to calculate the clearance distance after wind-deflected trees on horizontal land fall. This distance refers to the distance between the tree and the nearest point of the power transmission line or power equipment after the tree is tilted or fallen due to wind force or human felling on the side of the tree. This distance also needs to meet the requirements of safety regulations to prevent the tree from falling in strong winds or the wind-deflected trees from meeting the safety distance requirements of nearby power facilities, resulting in discharge accidents.

[0050] The second clearance distance calculation formula is used to calculate the clearance distance after a wind-blown tree falls on horizontal land. This calculation formula can be calculated using the following calculation formula:

[0051]

[0052] in, Indicates the clearance distance matched by the second requested scene mode, that is, the wind-induced tree-falling distance between the target tree and the target transmission line on the horizontal land, Indicates the second horizontal distance, Indicates the first horizontal distance, Indicates the height of the wire, Indicates the height of the tree.

[0053] In this embodiment, when the requested scene mode is the second requested scene mode, the calculation formula used may be: ,in, Indicates the clearance distance that matches the first requested scene mode, Indicates the second horizontal distance, Indicates the first horizontal distance, Indicates the height of the wire, Represents the tree height. Through this formula, the calculation of the wind-induced tree-falling distance between the target tree and the target transmission line on the horizontal land is realized, thereby improving the accuracy of the calculation of the wind-induced tree-falling distance between the target tree and the target transmission line on the horizontal land.

[0054] In one embodiment, the request scene mode includes: a third request scene mode for measuring the clearance distance of wind-biased trees on a slope; the height information of the target tree includes: the treetop height of the target tree; the intelligent computing module 102 is further used to use the third clearance distance calculation formula as the target clearance distance calculation formula when the request scene mode is the third request scene mode; obtain the clearance distance matching the third request scene mode through the third clearance distance calculation formula, the first horizontal distance, the second horizontal distance, the wire height, the tree height and the tree base height; the third clearance distance calculation formula is: ;in, Indicates the clearance distance that matches the third requested scene mode, Indicates the second horizontal distance, Indicates the first horizontal distance, Indicates the height of the wire, Indicates the height of the tree top.

[0055] In this embodiment, the request scene mode that matches the clearance distance acquisition request may be the third request scene mode, which can be used to calculate the clearance distance of wind-slanted trees on slopes, such as side slopes and slopes, that is, to calculate the clearance distance of wind-slanted trees on slopes. This distance refers to the distance between trees and power transmission lines or power equipment when the trees grow on the slope and are outside the wires and are not in the same vertical plane as the wires. The particularity of the slope makes the clearance distance of its trees different from that of flat ground. The clearance distance of trees needs to include the slope in the calculation scope to comprehensively calculate the accurate clearance distance of trees to meet the requirements of safety regulations.

[0056] The third clearance distance calculation formula is used to calculate the clearance distance of wind-biased trees on the slope. This calculation formula can be calculated using the following calculation formula:

[0057]

[0058] in, represents the clearance distance matched by the third request scene mode, that is, the wind-biased tree clearance distance between the target tree and the target transmission line on the horizontal land, Indicates the second horizontal distance, Indicates the first horizontal distance, Indicates the height of the wire, Indicates the height of the tree top.

[0059] In this embodiment, when the requested scene mode is the third requested scene mode, the calculation formula used may be: ,in, Indicates the clearance distance that matches the first requested scene mode, Indicates the second horizontal distance, Indicates the first horizontal distance, Indicates the height of the wire, The formula is used to calculate the wind-induced tree clearance distance between the target trees on the slope and the target transmission line, thereby improving the accuracy of the wind-induced tree clearance distance calculation between the target trees on the slope and the target transmission line.

[0060] In one embodiment, the request scene mode includes: a fourth request scene mode for measuring the clearance distance of wind-bent trees and fallen trees on a slope; the height information of the target tree includes: the tree height of the target tree and the tree base height of the target tree on the slope; the intelligent computing module 102 is further used to use the fourth clearance distance calculation formula as the target clearance distance calculation formula when the request scene mode is the fourth request scene mode; the clearance distance matching the fourth request scene mode is obtained by using the fourth clearance distance calculation formula, the first horizontal distance, the second horizontal distance, the wire height, the tree height and the tree base height; the fourth clearance distance calculation formula is: ;in, Indicates the clearance distance that matches the fourth requested scene mode, Indicates the second horizontal distance, Indicates the first horizontal distance, Indicates the height of the wire, Indicates the height of the tree, Indicates the tree base height.

[0061] In this embodiment, the request scene mode that matches the clearance distance acquisition request may be the fourth request scene mode, which can be used to calculate the distance of wind-biased trees on the slope after they fall, that is, to calculate the clearance distance after wind-biased trees on the slope fall. This distance refers to the distance between the nearest point of the tree and the nearby power facilities when the tree falls due to wind force or human felling. The clearance distance of wind-biased trees on the slope also needs to include the slope in the calculation scope to comprehensively calculate the accurate tree clearance distance to meet the requirements of safety regulations.

[0062] Therefore, in the fourth request scene mode, the height of the target tree on the slope needs to be considered, and the height can be represented by the tree base height of the target tree. In this embodiment, in addition to measuring the first horizontal distance between the multifunctional intelligent laser rangefinder and the target tree, the second horizontal distance between the multifunctional intelligent laser rangefinder and the target power transmission line, the wire height of the target power transmission line, and the tree height of the target tree, the laser ranging module 101 also needs to measure the tree base height of the target tree on the slope.

[0063] The fourth clearance distance calculation formula is used to calculate the clearance distance after the wind-bent trees on the slope fall down. This calculation formula can be calculated by the following calculation formula:

[0064]

[0065] in, represents the clearance distance matched by the fourth request scene mode, that is, the wind-induced tree-falling distance between the target tree on the slope and the target transmission line, Indicates the second horizontal distance, Indicates the first horizontal distance, Indicates the height of the wire, Indicates the height of the tree, Indicates the tree base height.

[0066] In this embodiment, when the requested scene mode is the fourth requested scene mode, the calculation formula used may be: ,in, Indicates the clearance distance that matches the first requested scene mode, Indicates the second horizontal distance, Indicates the first horizontal distance, Indicates the height of the wire, Indicates the height of the tree, It represents the height of the tree base. Through this formula, the distance between the target tree on the slope and the target transmission line due to wind deviation and the fallen tree is calculated, thereby improving the accuracy of the distance between the target tree on the slope and the target transmission line due to wind deviation and the fallen tree.

[0067] In one embodiment, the laser ranging module 101 is also used to measure the first horizontal distance and the tree base height of the target tree when the laser beam of the multifunctional intelligent laser rangefinder is focused on the tree base of the target tree; the laser ranging module 101 is also used to measure the tree top height of the target tree when the laser beam of the multifunctional intelligent laser rangefinder is focused on the tree top of the target tree; the tree height of the target tree is obtained according to the tree top height and the tree base height; the laser ranging module 101 is also used to measure the second horizontal distance and the wire height when the laser beam of the multifunctional intelligent laser rangefinder is focused on the target transmission wire.

[0068] In this embodiment, the multifunctional intelligent laser rangefinder also provides a target capture focusing function. When collecting data on a target object, the laser beam of the multifunctional intelligent laser rangefinder can be focused on the target object to perform distance measurement.

[0069] Specifically, when measuring the first horizontal distance between the multifunctional intelligent laser rangefinder and the target tree, and measuring the tree height of the target tree, it is first necessary to focus the laser beam of the multifunctional intelligent laser rangefinder on the tree base of the target tree, that is, the root of the tree, and then the user can press the measurement button. At this time, the laser ranging module 101 of the multifunctional intelligent laser rangefinder can record the horizontal distance and the vertical distance, wherein the horizontal distance can be used as the first horizontal distance, representing the horizontal distance between the multifunctional intelligent laser rangefinder and the target tree, and the vertical distance is used as the tree base height of the target tree.

[0070] Afterwards, it is necessary to focus the laser beam of the multifunctional intelligent laser rangefinder on the top of the target tree, that is, the root of the tree, and then the user can press the measurement button. At this time, the laser ranging module 101 of the multifunctional intelligent laser rangefinder can record the vertical distance, which is used as the treetop height of the target tree, and the difference between the treetop height and the tree base height is used as the tree height of the target tree.

[0071] Similarly, when measuring the second horizontal distance between the multifunctional intelligent laser rangefinder and the target transmission line, and measuring the conductor height of the target transmission line, it is necessary to focus the laser beam of the multifunctional intelligent laser rangefinder on the target transmission line, and then the user can press the measurement button. At this time, the laser ranging module 101 of the multifunctional intelligent laser rangefinder can record the horizontal distance and the vertical distance, wherein the horizontal distance can be used as the second horizontal distance, representing the horizontal distance between the multifunctional intelligent laser rangefinder and the target transmission line, and the vertical distance is used as the conductor height of the target transmission line.

[0072] In this embodiment, a focusing function can also be introduced into the laser ranging module to enhance the effective measurement distance. At the same time, it solves the problem that conventional rangefinders cannot capture target trees or target transmission lines when measuring reflections or bright light during the day, cannot measure target trees or target transmission lines, or have large measurement data errors. At the same time, selective target capture can better shield errors caused by other targets in the same area, thereby improving the ranging information accuracy of target trees or target transmission lines.

[0073] In one embodiment, the multifunctional intelligent laser rangefinder further includes: an angle measurement module, which is used to measure a first angle of a target transmission line when the laser beam of the multifunctional intelligent laser rangefinder is focused on the target transmission line; the angle measurement module is also used to measure a second angle of the target transmission line when the line direction of the target transmission line is deflected and the laser beam of the multifunctional intelligent laser rangefinder is focused on the target transmission line; the intelligent calculation module 102 is also used to obtain the turning angle of the target transmission line according to the difference between the second angle and the first angle.

[0074] In this embodiment, the multifunctional intelligent laser rangefinder includes not only the laser rangefinder module 101 and the intelligent computing module 102, but also an angle measurement module, which is used to measure basic angles such as horizontal angle, depression angle, and elevation angle. The intelligent computing module 102 then performs calculations based on the measured basic angles to obtain slope angles, turning angles, intersection angles, etc.

[0075] The calculation of the turning angle of the target transmission line can be achieved through the following process: first, the laser beam of the multifunctional intelligent laser rangefinder is focused on the target transmission line, and then the angle value of the target transmission line in the current direction can be obtained through the angle measurement module as the first angle of the target transmission line. Afterwards, after the wire direction of the target transmission line is deflected, the laser beam of the multifunctional intelligent laser rangefinder can be focused again on the target transmission line after the wire direction is deflected, and the angle value of the target transmission line in the direction after the wire direction is deflected can be obtained through the angle measurement module as the second angle of the target transmission line.

[0076] After the angle measurement module measures the first angle and the second angle, the intelligent calculation module 102 can further calculate the angle difference between the second angle and the first angle as the turning angle of the target transmission line.

[0077] In this embodiment, an angle measurement module can also be added to the multifunctional intelligent laser rangefinder to obtain the first angle and the second angle of the target transmission line before and after the line direction is deflected, so that the intelligent calculation module 102 obtains the turning angle of the target transmission line according to the angle difference between the second angle and the first angle. In this way, the multifunctional intelligent laser rangefinder is provided with a turning angle measurement function, further improving the functional diversity of the multifunctional intelligent laser rangefinder.

[0078] In addition, the angle measurement module is also used to measure the third angle of the crossed transmission conductor when the laser beam of the multifunctional intelligent laser rangefinder is focused on the crossed transmission conductor associated with the target transmission conductor; the crossed transmission conductor is a transmission conductor that crosses the target transmission conductor; the intelligent calculation module 102 is also used to obtain the crossing angle between the target transmission conductor and the crossed transmission conductor based on the difference between the third angle and the first angle.

[0079] In this embodiment, in addition to calculating the turning angle, the multifunctional intelligent laser rangefinder can also be used to calculate the crossing angle, which can be the angle generated when two transmission lines cross, where the crossing transmission line is a transmission line that crosses the target transmission line.

[0080] Specifically, after obtaining the first angle of the target transmission line through the angle measurement module, the laser beam of the multifunctional intelligent laser rangefinder can be focused on the cross transmission line, and the angle value of the cross transmission line can be obtained by the angle measurement module as the third angle of the cross transmission line. And after the angle measurement module obtains the first angle and the third angle, the intelligent calculation module 102 can be further used to calculate the angle difference between the third angle and the first angle as the cross angle between the target transmission line and the cross transmission line.

[0081] In this embodiment, the angle measurement module can also be used to obtain a third angle of the crossing transmission line that crosses the target transmission line, so that the intelligent calculation module 102 obtains the crossing angle of the target transmission line and the crossing transmission line based on the angle difference between the third angle and the first angle. In this way, the multifunctional intelligent laser rangefinder is provided with a crossing angle measurement function, further improving the functional diversity of the multifunctional intelligent laser rangefinder.

[0082] In one embodiment, as shown in FIG. 2 , a method for obtaining a clearance distance is also provided. The method can be applied to the multifunctional intelligent laser rangefinder as described in any of the above items. In this embodiment, the method includes the following steps:

[0083] Step S201, in response to a clearance distance acquisition request triggered by a user, acquiring a request scene mode that matches the clearance distance acquisition request; the clearance distance acquisition request is used to acquire the clearance distance between a target tree and a target transmission line.

[0084] Among them, the clearance distance acquisition request refers to the request initiated by the user for calculating the clearance distance between the target tree and the target transmission line, and the request scene mode refers to the scene corresponding to the triggered clearance distance acquisition request, for example, it may include: the scene of obtaining the clearance distance of wind-bent trees, the scene of obtaining the clearance distance of wind-bent trees on slopes, the scene of obtaining the distance of fallen trees on slopes due to wind-bent trees, etc.

[0085] Specifically, when the user needs to obtain the clearance distance between the target tree and the target transmission line, the user can initiate a clearance distance acquisition request by inputting a request scene mode through the multifunctional intelligent laser rangefinder. At this time, the multifunctional intelligent laser rangefinder can respond to the above clearance distance acquisition request to obtain a request scene mode that matches the clearance distance acquisition request.

[0086] Step S202, measuring a first horizontal distance between the multifunctional intelligent laser rangefinder and the target tree, a second horizontal distance between the multifunctional intelligent laser rangefinder and the target power transmission line, a height of the target power transmission line, and height information of the target tree.

[0087] The first horizontal distance, the second horizontal distance, the conductor height and the height information are respectively the distance data that need to be measured when calculating the clearance distance between the target tree and the target transmission line. The first horizontal distance refers to the horizontal distance between the placement position of the multifunctional intelligent laser rangefinder and the target tree, the second horizontal distance refers to the horizontal distance between the placement position of the multifunctional intelligent laser rangefinder and the target transmission line, the conductor height refers to the height of the target transmission line, and the height information refers to the height information associated with the tree, such as the tree height, the tree base height and the tree top height, etc.

[0088] After receiving the clearance distance acquisition request, the multifunctional intelligent laser rangefinder can measure the data used to calculate the clearance distance according to the requested scene mode, that is, measure the first horizontal distance, the second horizontal distance, the wire height and the height information.

[0089] Step S203 : acquiring a target clearance distance calculation formula that matches the requested scene mode from a plurality of pre-stored clearance distance calculation formulas.

[0090] The clearance distance calculation formula is a calculation formula used to calculate the clearance distance. Each calculation formula is used to calculate the clearance distance of different scene modes, and the target clearance distance calculation formula refers to the clearance distance calculation formula that matches the request scene mode corresponding to the clearance distance acquisition request. Specifically, the multifunctional intelligent laser rangefinder can further select the target clearance distance calculation formula that matches the request scene mode from the multiple clearance distance calculation formulas stored in the multifunctional intelligent laser rangefinder according to the request scene mode.

[0091] Step S204, using the target clearance distance calculation formula, the first horizontal distance, the second horizontal distance, the wire height and the height information, obtain the clearance distance between the target tree and the target transmission wire that matches the requested scene mode.

[0092] Finally, the multifunctional intelligent laser rangefinder can also use the target clearance distance calculation formula, as well as the measured first horizontal distance, second horizontal distance, wire height and height information to calculate the clearance distance between the target tree and the target transmission line. For example, the multifunctional intelligent laser rangefinder can substitute the measured first horizontal distance, second horizontal distance, wire height and height information into the target clearance distance calculation formula to obtain the clearance distance between the target tree and the target transmission line.

[0093] In the above-mentioned clearance distance acquisition method, a request scene mode matching the clearance distance acquisition request is acquired by a multifunctional intelligent laser rangefinder in response to a clearance distance acquisition request triggered by a user; the clearance distance acquisition request is used to acquire the clearance distance between a target tree and a target power transmission line; the first horizontal distance between the multifunctional intelligent laser rangefinder and the target tree, the second horizontal distance between the multifunctional intelligent laser rangefinder and the target power transmission line, the height of the target power transmission line, and the height information of the target tree are measured; a target clearance distance calculation formula matching the request scene mode is acquired from a plurality of pre-stored clearance distance calculation formulas; and the clearance distance between the target tree and the target power transmission line matching the request scene mode is obtained by using the target clearance distance calculation formula, the first horizontal distance, the second horizontal distance, the height of the line, and the height information. The clearance distance acquisition method provided in the present application can obtain the scene mode corresponding to the clearance distance acquisition request when the multifunctional intelligent laser rangefinder receives the clearance distance acquisition request triggered by the user, and can obtain the first horizontal distance between the multifunctional intelligent laser rangefinder and the target tree, the second horizontal distance between the multifunctional intelligent laser rangefinder and the target transmission line, the line height of the target transmission line and the height information of the target tree, thereby using the target clearance distance calculation formula matching the requested scene mode, and the above-mentioned first horizontal distance, second horizontal distance, line height and height information to obtain the clearance distance between the target tree and the target transmission line that matches the requested scene mode. In this way, the multifunctional intelligent laser rangefinder can directly output the clearance distance between the tree and the transmission line, without the need for the user to manually calculate the clearance distance based on the distance measurement result, thereby improving the accuracy of clearance distance acquisition.

[0094] In one embodiment, a multifunctional intelligent laser rangefinder is also provided, which integrates the measurement functions of wind-biased tree clearance, wind-biased tree clearance on slopes, fallen tree distance on slopes, cross-over distance, turning angle, cross-over angle, etc.; the multifunctional intelligent laser rangefinder has diversified measurement functions, increases the application scenarios of on-site measurement, and can better meet the production measurement needs. Secondly, the multifunctional intelligent laser rangefinder has a capture and focus function to increase the effective measurement distance. The instrument can capture the target and complete the measurement when the wire is reflected or the light is bright during the day. At the same time, it automatically focuses on the selected measurement target to avoid the instrument selecting other targets in the same area to cause measurement errors, thereby improving the measurement accuracy of the instrument. Secondly, the multifunctional intelligent laser rangefinder has functions such as intelligent calculation, that is, after the measuring instrument measures the number, the measurement result can be obtained through the instrument calculation. Intelligent calculation can also reduce the errors introduced by measurement and calculation, and simplify the complexity of measurement and calculation, making the measurement operation simpler, more convenient, efficient and accurate, saving operation time, data calculation time, and improving work efficiency; and while saving manpower and material resources, it can also improve the measurement accuracy of the instrument. At the same time, the instrument can adapt to more people, so that surveyors who cannot calculate can also complete the measurement work smoothly and efficiently.

[0095] Specifically, the multifunctional intelligent laser rangefinder is composed of a combination of hardware and software such as a laser rangefinder module, an angle measurement module, and an intelligent algorithm module. The specific functions of each module include the following:

[0096] 1. Angle measurement module:

[0097] The multifunctional intelligent laser rangefinder is equipped with an angle measurement module, that is, the rangefinder is equipped with basic angle measurements such as horizontal intersection, depression angle, elevation angle, etc., and the slope angle, turning angle, intersection angle, etc. are calculated through the calculation formula of the calculation module.

[0098] 1. Angle measurement:

[0099] The target turns in the original direction , calculate the turning angle. Taking the transmission line as an example, first align the laser beam of the laser rangefinder with the direction of the original transmission line and read the angle , then align the transmission line with the direction of rotation to read the angle , the absolute value of the angle difference between the two is the rotation angle, and the calculation formula is: .

[0100] 2. Cross angle measurement:

[0101] Find the intersection angle when two targets intersect Taking the transmission line as an example, first aim the laser beam of the laser rangefinder at one of the lines to read the angle Then aim the laser beam of the laser rangefinder in the direction of another line to read the angle , the absolute value of the angle difference between the two is the intersection angle, and the calculation formula is: .

[0102] 2. Laser ranging module:

[0103] The multifunctional intelligent laser rangefinder laser distance measurement module is mainly used to measure the vertical distance, horizontal distance, slant distance, etc. of targets such as trees and towers, and then calculate the specific measurement method as follows:

[0104] 1. Select the measurement location:

[0105] Find a location that is an appropriate distance from the target (for example, trees and power lines), make sure the laser rangefinder can see directly at the top of the tree, and then determine the measurement target by selecting the target and focusing.

[0106] 2. Horizontal measurement:

[0107] Aim the laser beam of the laser rangefinder at the base or top of the tree, then press the measurement button and record this distance, the horizontal distance, as HD.

[0108] 3. Tree base measurement:

[0109] Aim the laser rangefinder's laser beam at the base (root) of the tree, then press the measurement button and record this distance as VD1.

[0110] 4. Measure the height of the tree top:

[0111] Aim the laser rangefinder at the top of the tree, measure the distance from the instrument to the treetop, and record this distance as VD2.

[0112] 5. Measuring the height of transmission lines:

[0113] Aim the laser rangefinder at the transmission line, measure the distance from the instrument to the line, and record this distance as VD3.

[0114] 6. Calculate tree height:

[0115] The calculation formula for tree height H is: H=VD2-VD1.

[0116] 7. Calculate the clearance distance between trees and transmission lines:

[0117] The calculation formula for the clearance distance SD between trees and transmission lines is: SD=VD3-VD2.

[0118] Note that when measuring distance, the two targets need to be on the same horizontal plane to ensure that the obtained height is accurate.

[0119] 3. Intelligent algorithm module:

[0120] The intelligent algorithm module of the multifunctional intelligent laser rangefinder can directly obtain the measurement results through the intelligent calculation formula of the instrument through the on-site measurement data. That is, after measuring the basic data on-site according to the measurement and calculation requirements, the clearance of wind-biased trees, the clearance of wind-biased trees on the slope, and the clearance distance of fallen trees on the slope can be calculated. It not only reduces the errors introduced by measurement and calculation, but also simplifies the complexity of measurement and calculation, making the measurement operation simpler, more convenient, efficient and accurate, saving operation time, data calculation time, and improving work efficiency. It also saves manpower and material resources, and can improve the measurement accuracy of the instrument. At the same time, the instrument can adapt to more people, so that surveyors who cannot calculate can also complete the measurement work smoothly and efficiently.

[0121] Specifically, the wind-induced tree clearance distance and fallen tree distance measurement can be achieved through the following process:

[0122] There are two situations for wind-bent trees: one is the measurement of the clearance distance and fallen tree distance of wind-bent trees on horizontal land with a slope of 0°; the other is the measurement of the clearance distance and fallen tree distance of wind-bent trees on a slope or slope, where:

[0123] Wind-induced tree clearance distance: refers to the distance between trees and transmission lines or power equipment when the trees are outside the target (taking transmission lines as an example), that is, the trees are outside the lines and are not in the same vertical plane as the lines. This distance needs to meet the requirements of safety regulations to prevent the trees from falling in strong winds or the wind-induced safety distance from nearby power facilities from not meeting the requirements and causing discharge accidents.

[0124] Wind-deflected tree falling distance: refers to the distance between the tree and the transmission line or power equipment at the closest point after the tree is tilted or fallen due to wind or human felling. This distance needs to meet the requirements of safety regulations to prevent the tree from falling in strong winds or the wind-deflected tree from meeting the safety distance requirements for nearby power facilities, resulting in discharge accidents.

[0125] Slope wind deflection tree clearance: the distance between trees and transmission lines or power equipment when the trees grow on the slope and are outside the conductors and are not in the same vertical plane as the conductors. The particularity of the slope makes the tree clearance distance different from that of flat ground. The tree clearance distance needs to include the slope in the calculation scope and comprehensively calculate the accurate tree clearance distance to meet the requirements of safety regulations.

[0126] The distance between fallen trees due to wind deflection on slopes refers to the distance between the nearest point of trees and nearby power facilities when trees on slopes fall due to wind or human felling. The clearance distance between fallen trees due to wind deflection on slopes also needs to include the slope in the calculation scope to comprehensively calculate the accurate tree clearance distance to meet the requirements of safety regulations.

[0127] The specific implementation may include the following processes:

[0128] (1) Calculation of wind-induced tree clearance distance:

[0129] As shown in Figure 3, the specific calculation formula is as follows:

[0130] .

[0137] VD line: the height of the transmission line.

[0138] (2) Calculation of the distance to fallen trees caused by wind:

[0139] As shown in Figure 4, the specific calculation formula is as follows:

[0148] (3) Calculation of the distance to fallen trees due to wind deflection on slopes:

[0149] As shown in Figure 5, the specific calculation formula is as follows:

[0150] .

[0151] The multifunctional intelligent laser rangefinder provided in this embodiment has an additional angle measurement function, that is, it has added the rangefinder slope angle, corner angle, cross-cross angle and other measurement functions, so that the multifunctional intelligent laser rangefinder has diversified measurement functions, which solves the problem that conventional laser rangefinders have a single measurement function, few application scenarios, and cannot meet production measurement needs. In addition, a target capture focus function is added and the effective measurement distance is increased, which not only solves the defect that conventional rangefinders cannot capture targets, cannot measure targets, or have large measurement data errors when measuring target reflections or bright light during the day, but also selectively captures targets to shield errors caused by other targets in the same area, thereby improving the measurement accuracy of the instrument; and the increase in the effective distance of the rangefinder can meet the measurement of large-span channels, can adapt to more application scenarios and environments, and can better meet production needs. At the same time, functions such as intelligent calculation are added. That is, after the measuring instrument measures the number, the instrument can calculate the data results such as the clearance of wind-biased trees, the clearance of wind-biased trees on the slope, and the distance of fallen trees on the slope. Intelligent calculation effectively reduces the errors introduced by measurement and calculation, improves the measurement accuracy, and also reduces the complexity of measurement and calculation. The multifunctional intelligent laser rangefinder makes the measurement operation simpler, more convenient, efficient and accurate. It not only saves operation time and manpower and material resources, and improves work efficiency, but also can adapt to more people, so that surveyors who cannot calculate can also complete the measurement work smoothly and efficiently, effectively solving the problems of complex measurement and calculation and low measurement accuracy of conventional laser rangefinders.
