DETAILED DESCRIPTION

[0033] Embodiment 1, as Figure 1-Figure 2 As shown, a geographic information land area measurement device proposed by the present invention includes a plurality of measurement units 1 used in series; the measurement unit 1 includes a support column 101, a connection storage cylinder 102, a guide belt 103, a laser measurement assembly, a guide piece 105 and a data collector 106; the support column 101 is used for fixing and height adjustment; the connection storage cylinder 102 is located on the support column 101; one end of the guide belt 103 is stored in the connection storage cylinder 102, and the other end is connected to the adjacent connection storage cylinder 102; the laser measurement assembly is located at the upper and lower ends of the connection storage cylinder 102, including a laser emitting element 104 and a laser receiving element 107; a plurality of guide pieces 105 are arranged along the guide belt 103, and the position is adjustable, and an upper and a lower guide window 10504 for the laser to pass through is arranged thereon, which guides the laser emission routes of the upper and lower laser emitting elements 104 respectively; the laser measurement assembly at the upper end of the data collector 106 is used to collect and summarize the area-related data between adjacent measurement units 1.

[0034] It should be further explained that the bottom of the support column 101 is provided with a tip, and the top is provided with a telescopic end; when in use, the appropriate measurement point position and number are selected along the edge of the land, and the corresponding number of measurement units 1 are inserted into the ground at the corresponding measurement points in sequence using the tip. The telescopic end can be set to be electrically controlled, and the position of the connecting storage tube 102 is adjusted by telescoping, so that the guide belt 103 is level with the ground, and the laser is also emitted horizontally, thereby reducing measurement errors.

[0035] It should be further explained that the data collector 106 includes a positioning module, an angle data collection module, a length data collection module, a land simulation module, a measurement and analysis module, and a data transmission module; by laser ranging, the data (length and angle) of each side of the divided land is collected in sequence, and the land simulation map and the area of ​​each divided land can be obtained, and the total land area can be obtained after accumulation. The staff directly receives the summary data and map through the terminal. The land area measurement is accurate and convenient, and the display effect is intuitive.

[0036] like Figure 3 As shown, the connection storage cylinder 102 includes a hollow cylinder 10201; a group of openings 10203 and multiple groups of connectors 10202 are set on the side wall of the cylinder 10201, a circle of laser receiving components 107 are set at the upper and lower ends of the cylinder 10201, and a movable laser emitting component 104 is also set, and the inside of the cylinder 10201 is connected to the tail end of the guide belt 103; the head end of the guide belt 103 passes through the cylinder 10201 through the opening 10203; after the measurement unit 1 is fixed, the guide belt 103 is stretched to the adjacent measurement unit 1, and the guide belt 103 is fixed by the connector 10202. After the land is divided and surrounded by multiple guide belts 103, the divided areas can be measured in sequence by laser.

[0037] It should be further explained that a belt winding shaft 10204 is arranged inside the cylinder 10201 ; the middle part of the belt winding shaft 10204 is wound around the tail of the guide belt 103 , and both ends extend into the installation sleeve 10206 respectively, and are connected to the installation sleeve 10206 through a torsion spring 10205 .

[0038] The torsion spring 10205 is stretched when the guide belt 103 is pulled out, and assists the guide belt 103 to reset after use. The guide belt 103 is stored in the cylinder 10201 for easy storage and small space occupation.

[0039] like Figure 4-Figure 5 As shown, a plurality of mounting holes 10301 for mounting the guide member 105 are arranged on the guide belt 103; at least two groups of guide members 105 are arranged, including a sleeve 10501; the sleeve 10501 is slidably sleeved on the guide belt 103 through a sliding channel 10502, a clamping rod 10507 is arranged in the middle of the sleeve 10501 and slides through the sliding channel 10502 and the mounting hole 10301, and a mounting ring 10503 is arranged at the end; a limit seat 10505 is arranged at one end of the clamping rod 10507, and a reset spring 10508 is sleeved at the same time; the reset spring 10508 is located between the limit seat 10505 and the sleeve 10501; a guide window 10504 is arranged in the mounting ring 10503, and a circle of distance sensors is arranged on the outer periphery.

[0040] It should be further explained that the mounting holes 10301 are matched in pairs one above the other and multiple groups are arranged at equal intervals on the guide belt 103 ; and two groups of clamping rods 10507 are correspondingly arranged on each group of sliding sleeves 10501 .

[0041] After the guide belt 103 is pulled out to connect with the adjacent cylinder 10201, the clamping rod 10507 can be pressed to make it withdraw from the sliding channel 10502. The sliding sleeve 10501 can adjust the position and spacing of the two sets of guide members 105. Finally, the clamping rod 10507 is clamped on the corresponding mounting hole 10301. Since two sets of mounting holes 10301 are provided one above the other, it is convenient for the sleeve 10501 to remain vertical. Since two sets of guide members 105 are provided, it is convenient to determine the measurement route of the laser. During measurement, the laser needs to pass through the two sets of guide windows 10504 in sequence. The distance sensor determines whether it passes through the center position, so that the measurement route of the laser is accurate and controllable.

[0042] like Figure 6 As shown, multiple groups of connectors 10202 are radially arranged along the outer circumference of the cylinder 10201, and each group of connectors 10202 is provided with a T-shaped cross-section groove; a block 10302 matching the groove is provided at the head end of the guide belt 103.

[0043] It should be further explained that the card block 10302 is magnetically connected to the slot wall of the card slot.

[0044] When connecting, the guide belt 103 is stretched to the adjacent cylinder 10201. According to the shape of the edge of the land to be measured, the connector 10202 is selected at a suitable position, and the clamping block 10302 is clamped into the corresponding clamping slot, so that the length direction of the guide belt 103 is perpendicular to the width direction of the clamping block 10302, and the guide belt 103 can be positioned. The direction of the guide belt 103 is the measurement route of the laser.

[0045] like Figure 7 As shown, two sets of slide rails 10208 arranged in a mirrored manner are respectively provided at the upper and lower ends of the cylinder 10201; the two sets of slide rails 10208 are arranged in a ring shape around the cylinder mouth of the cylinder 10201, and a ring-shaped detection groove 10207 is arranged between the two sets of slide rails 10208; multiple groups of laser receiving elements 107 are arranged along the detection groove 10207; and the laser emitting element 104 is slidably set between the two sets of slide rails 10208.

[0046] When multiple measuring units 1 are connected in series, a group of laser emitting elements 104 can emit detection lasers along the direction of the guide belt 103 to the detection slots 10207 of the adjacent cylinders 10201 , and be sensed in place by the laser receiving element 107 .

[0047] It should be further explained that the laser emitting element 104 includes a moving seat 10401 that moves along two sets of upper and lower slide rails 10208; a mounting groove is set at the front end of the moving seat 10401; and the laser emitter 10402 is rotatably set in the mounting groove.

[0048] It should be further explained that moving wheels matching the slide rail 10208 are arranged at the upper and lower ends of the moving seat 10401, which are driven by the driving engine inside the moving seat 10401, and move along the slide rail 10208 as a whole to achieve a 360-degree rotation; a motor is arranged at the front end of the moving seat 10401; the laser emitter 10402 is driven by motor 1 and rotates in the horizontal direction.

[0049] By moving and rotating the laser emitter 10402 , the position and angle of laser emission are adjusted to match the guidance of the guide member 105 , so that the laser measurement route matches the direction of the guide belt 103 .

[0050] It should be further explained that at least three groups of measuring units 1 are required to enclose the land to be measured. The specific number of settings and the connection method can be divided according to the size and shape of the land. Figure 8-Figure 10 As shown, for a piece of land A, multiple methods can be used to measure it. Method 1: Set four groups of measurement units 1, surround its edges into a quadrilateral, obtain the length and angle of each side in turn, and finally get the area data. Method 2: Set five groups of measurement units 1 to divide the land A into four triangles, A1, A2, A3 and A4. Obtain the length and angle of each triangle in turn to obtain a single area data, and then accumulate to obtain the total area data. Method 3: Set five groups of measurement units 1 to divide the land A into two triangles, A1 and A2. Obtain the length and angle of each triangle in turn to obtain a single area data, and then accumulate to obtain the total area data. By setting the appropriate number and series method, the division effect can be closer to the actual situation of the land, thereby obtaining more accurate measurement data.

[0051] Embodiment 2: Based on the geographic information land area measurement device in Embodiment 1, this embodiment proposes a geographic information land area measurement method, and the steps are as follows: S1. Select multiple measurement points based on the shape and size of the land; S2. Use the tip to vertically insert a corresponding number of measuring units 1 on the ground at corresponding measuring points in sequence, and adjust the position of the connecting storage tube 102 by telescoping; S3, the guide belt 103 is extended to the adjacent measuring unit 1, and the connector 10202 is selected at a suitable position according to the edge shape of the land to be measured, and the card block 10302 is inserted into the corresponding card slot so that the length direction of the guide belt 103 is perpendicular to the width direction of the card block 10302, and the guide belt 103 can be positioned; the guide belt 103 divides the land into multiple areas to be measured; S4, press the clamping rod 10507 to make it withdraw from the sliding channel 10502, and slide the sliding sleeve 10501 to adjust the position and spacing of the two sets of guide members 105; finally, clamp the clamping rod 10507 on the corresponding mounting hole 10301; S5. Start measuring. By moving and rotating the laser emitter 10402, adjust the position and angle of laser emission until each group of lasers passes through the center of the two groups of guide windows 10504 in sequence and is finally received by the corresponding laser receiver 107, so that the data (length and angle) of the edge can be obtained. S6. Collect the data of each edge of the divided land in sequence to obtain a land simulation map and the area of ​​each divided area. After accumulation, the total land area can be obtained; the staff directly receives the summary data and map through the terminal.

[0052] The embodiments of the present invention are described in detail above with reference to the accompanying drawings, but the present invention is not limited thereto, and various changes can be made within the knowledge scope of technicians in the relevant technical field without departing from the purpose of the present invention.
