Description

Improved measuring device and method for raised floor units This invention relates to an improved measuring device and method for a raised floor unit; particularly to an improved measuring device and method for a raised floor unit capable of measuring the side length and squareness of the floor unit, and further capable of measuring the height of the four legs. Raised floors are now widely used in computer rooms, clean rooms, and other similar spaces. A raised floor typically consists of at least four legs, at least four crossbeams, and at least one floor unit. It provides a highly flat surface above the floor, facilitates the installation of piping, and allows for easy control of cleanliness levels. The floor unit is a crucial structural element of the entire factory building. However, conventional methods for measuring floor units mostly rely on manual measurement, which is both time-consuming and costly. To address the aforementioned issues, the inventors in this case disclosed various measuring devices in Republic of China patents M659935, M658755, and M658754. However, none of the aforementioned three patents included a measuring device or method for the squareness of floor units, thus leaving room for improvement. In view of this, the inventor pondered deeply, conducted active research, and combined his many years of experience in related product research with continuous experimentation and improvement, finally developing this invention. The purpose of this invention is to provide an improved measuring device for raised floor units that can measure the side length and squareness of floor units. The structure of the present invention achieving the above-mentioned objective includes: a first platform; a clamping mechanism disposed on the first platform for clamping a floor unit on the first platform; the clamping mechanism having a front positioning structure and a left positioning structure to define a front reference line and a left reference line that are perpendicular to each other; a first side length measuring device disposed on the left side of the first platform; a second side length measuring device disposed on the left side of the first platform; a third side length measuring device disposed on the rear side of the first platform; a fourth side length measuring device disposed on the rear side of the first platform; a fifth side length measuring device disposed on the right side of the first platform; and a sixth side length measuring device disposed on the right side of the first platform. Side-top; a side length measurement method, the error data of the side length is obtained by subtracting the measurement information obtained by the third side length measuring device and the fourth side length measuring device, and the error data of the side length is obtained by subtracting the measurement information obtained by the fifth side length measuring device and the sixth side length measuring device; a squareness measurement method, the squareness of the left edge is obtained by subtracting the measurement information of the second side length measuring device from the measurement information of the first side length measuring device, the squareness of the rear edge is obtained by subtracting the measurement information of the fourth side length measuring device from the measurement information of the third side length measuring device, and the squareness of the right edge is obtained by subtracting the measurement information of the sixth side length measuring device from the measurement information of the fifth side length measuring device. Preferably, the clamping mechanism has two front fixed roller seats and two rear sliding roller seats. The two rear sliding roller seats push the floor unit to the two front fixed roller seats, so that the front edge of the floor unit overlaps with the front reference line. The error data of the side length is obtained by subtracting the measurement information obtained by the third side length measuring instrument and the fourth side length measuring instrument, which can reduce the error caused by possible poor squareness. Preferably, the clamping mechanism has two left fixed roller seats and one right sliding roller seat. The right sliding roller seat pushes the floor unit to the two left fixed roller seats, so that the left edge of the floor unit overlaps with the left reference line. The error data of the side length is obtained by subtracting the measurement information obtained by the fifth side length measuring instrument and the sixth side length measuring instrument, which can reduce the error caused by possible poor squareness. Preferably, the floor unit is first pushed to the two front fixed roller seats using two rear sliding roller seats, so that the front edge overlaps with the front reference line. Then, the floor unit is pushed to the two left fixed roller seats using one right sliding roller seat, so that at least one point on the left edge overlaps with the left reference line. The first to sixth squareness measurement information can be obtained by measuring the first to sixth squareness measurement information using the first to sixth side length measuring instruments. Subtracting the measurement information of the second side length measuring instrument from the measurement information of the first side length measuring instrument yields the squareness of the left edge corresponding to the right edge. Subtracting the measurement information of the fourth side length measuring instrument from the measurement information of the third side length measuring instrument yields the squareness of the rear edge corresponding to the front edge. Subtracting the measurement information of the sixth side length measuring instrument from the measurement information of the fifth side length measuring instrument yields the squareness of the right edge corresponding to the left edge. Preferably, before measuring the squareness, a standard block is first pushed to the two front fixed roller seats using the two rear sliding roller seats, so that the front edge of the standard block overlaps with the front reference line. Then, the standard block is pushed to the two left fixed roller seats using the right sliding roller seat, so that the left edge of the standard block overlaps with the left reference line. The measurements of the first side length measuring device to the sixth side length measuring device are then zeroed. Finally, the two rear sliding roller seats, the right sliding roller seat, and the first side length measuring device to the sixth side length measuring device are returned to their original positions to facilitate subsequent measurement of the squareness of the floor unit.

[Figure 17] is a schematic diagram of the present invention, which includes a floor sensor and an automatic floor barcode scanner. As shown in Figures 1-17, the improved measuring device 100 for raised floor units of the present invention includes: a first platform 1; a clamping mechanism 2 disposed on the first platform 1 to clamp a floor unit 101 on the first platform 1; the clamping mechanism 2 has a front positioning structure 21 and a left positioning structure 22 to define a mutually perpendicular front reference line L11 and a left reference line L12; a first side length measuring device to a sixth side length measuring device 31, 32, 33, 34, 35, 36 are located on the same plane and arranged on the left, rear, and right sides of the floor unit 101; a side length measuring means and a squareness measuring means can respectively measure the side length and squareness of the floor unit through the clamping mechanism 2 in different clamping methods. This will be described in detail below. This invention can be used to measure, for example, honeycomb floor units (not shown in the figure), grid floor units (not shown in the figure), window floor units (not shown in the figure), blind floor units (hereinafter referred to as blind plates, this invention takes blind plates as an example) and other types of floor units 101. The first platform 1 can be a steel frame structure, which is simply illustrated as a flat plate in Figures 2-9 and Figure 17. As shown in Figures 1 and 2, the front positioning structure 21 of the clamping mechanism 2 can be composed of two front fixed roller seats 211. The two front fixed roller seats 211 form the front reference line L11. In addition, the left positioning structure 22 can be composed of two left fixed roller seats 221, and the two left fixed roller seats 221 form a left reference line L12 perpendicular to the front reference line L11. As shown in Figure 3, the clamping mechanism 2 may further include a rear pushing mechanism 23 and a right pushing mechanism 24. The rear pushing mechanism 23 may be composed of two rear sliding roller seats 231, and the right pushing mechanism 24 may be composed of a right sliding roller seat 241. These mechanisms can push the floor unit 101 from the rear and right sides respectively, causing the front edge 1011 and left edge 1012 of the floor unit to rest against the two front fixed roller seats 211 and the two left fixed roller seats 221, thereby fixing the floor unit 101 for measurement. After measurement, the rear pushing mechanism 23 and the right pushing mechanism 24 can be returned to their original positions for easy replacement of the tested floor unit 101. As shown in Figures 3-5, the two front fixed roller seats 211 and the two left fixed roller seats 221 have the same structure. Taking the front fixed roller seat 211 as an example, it can be composed of a base 2111 and a rotatable roller 2112 disposed on the base. The rear sliding roller seat 231 and the right sliding roller seat 241 have the same structure. Taking the right sliding roller seat 241 as an example, it can be composed of a slide rail base 2411 with a slide rail 2412 on the top, a sliding base 2413 slidably mounted on the slide rail base, a rotatable roller 2414 mounted on the sliding base, and a pneumatic cylinder 2415 that drives the sliding base 2413 to move closer to or away from the floor unit 101 along the slide rail 2412 of the slide rail base 2411. With this structure, friction damage to the perimeter of the floor unit 101 can be avoided when the clamping mechanism 2 pushes the floor unit 101. The first to sixth side length measuring devices 31, 32, 33, 34, 35, and 36 have the same structure. Taking the fifth side length measuring device 35 as an example, it can have: a side length base 351, fixed on the first platform 1, with a slide rail 352 on the side length base; a side length displacement gauge 353, slidably mounted on the slide rail of the side length base; and a side length pneumatic cylinder 354, which drives the side length displacement gauge to move closer to or away from the floor unit along the slide rail. The front edge 1011 of the floor unit 101 overlaps with the front reference line, serving as the primary reference for measurement. Therefore, it is not necessary to install a side length measuring device on the front side. Measurements can be completed simply by installing the first to sixth side length measuring devices 31, 32, 33, 34, 35, and 36 on the left, rear, and right sides of the floor unit. For example, the first side length measuring device 31 measures the left edge of the floor unit near the front; the second side length measuring device 32 measures the left edge of the floor unit near the rear; the third side length measuring device 33 measures the rear edge of the floor unit near the left; the fourth side length measuring device 34 measures the rear edge of the floor unit near the right; the fifth side length measuring device 35 measures the right edge of the floor unit near the front; and the sixth side length measuring device 36 measures the right edge of the floor unit near the rear. The improved measuring device 100 of the raised floor unit may further include a controller. The controller may be, for example, a computer or a programmable logic controller (PLC) (not shown in the figure), for controlling the clamping mechanism 2, the first side length measuring devices to the sixth side length measuring devices 31, 32, 33, 34, 35, 36 and other components. The side length measurement method can be a program code recorded in the controller, which obtains the lengths of the front edge 1011, left edge 1012, rear edge 1013, and right edge 1014 of the floor unit based on the measurement results of the third to sixth side length measuring devices 33, 34, 35, and 36. Based on this structure, the present invention further discloses an improved measurement method for a raised floor unit. The improved measurement method for a raised floor unit of the present invention includes at least the following steps (S10) to (S15). The present invention uses a clamping mechanism 2 to clamp the floor unit 101, so it can be used to measure floor units of various different sizes and specifications. Therefore, when measuring floor units of the same size and specification, a zeroing operation can be performed first using a sample plate that conforms to the standard size. S10) A clamping mechanism 2 is used to make the front edge 1011 of a floor unit 101 overlap with a front reference line L11. In step S10), the floor unit 101 can be pushed by two rear sliding roller seats 231, so that the front edge 1011 of the floor unit 101 rests on two front fixed roller seats 211, thereby making the front edge 1011 overlap with the front reference line L11. S11) A third side length measuring device is used to measure the position of the rear edge 1013 of the floor unit 101 near the left side to obtain a first side length measurement information, and a fourth side length measuring device 34 is used to measure the position of the rear edge 1013 of the floor unit 101 near the right side to obtain a second side length measurement information. As shown in FIG6, step S11) can be completed by using the side length pneumatic cylinders of the third to fourth side length measuring devices 33 and 34 to drive the side length displacement gauge close to the floor unit. S12) The length of the left edge 1012 of the floor unit is obtained by means of the first side length measurement information and the front reference line, and the length of the right edge 1014 of the floor unit is obtained by means of the second side length measurement information and the front reference line; the clamping mechanism 2, the third side length measuring device 33 and the fourth side length measuring device 34 return to the origin (as shown in Figure 3). S13) The clamping mechanism 2 is used to make the left edge 1012 of the floor unit 101 overlap with a left reference line L12. In step S13), the floor unit 101 can be pushed by the right sliding roller seat 241 so that the left edge 1012 of the floor unit 101 rests against the left fixed roller seat 221, thereby making the left edge 1012 overlap with the left reference line L12. S14) A fifth side length measuring device 35 measures the position of the right edge 1014 of the floor unit near the front to obtain a third side length measurement information, and a sixth side length measuring device 36 measures the position of the right edge 1014 of the floor unit near the rear to obtain a fourth side length measurement information. As shown in FIG7, step S14) can be completed by using the side length pneumatic cylinders of the fifth to sixth side length measuring devices 35 and 36 to drive the side length displacement gauge close to the floor unit. S15) The length of the front edge 1011 of the floor unit is obtained by the side length measurement method based on the third side length measurement information and the left baseline, and the length of the rear edge 1013 of the floor unit is obtained based on the fourth side length measurement information and the left baseline; the clamping mechanism 2, the fifth side length measuring device 35 and the sixth side length measuring device 36 return to the origin (as shown in Figure 3). As described in steps S10) to S15), when measuring the length of the front edge 1011 and the rear edge 1013 of the floor unit 101, the left edge 1012 and the left reference line L12 are used as the basis. When measuring the length of the left edge 1012 and the right edge 1014 of the floor unit 101, the front edge 1011 and the front reference line L11 are used as the basis. This can reduce the error caused by possible poor squareness and thus obtain a more accurate side length of the floor unit 101. Furthermore, when measuring the side length, the floor unit is first pushed to the front fixed roller seat 211 by the two rear sliding roller seats 231, so that the front edge 1011 overlaps with the front reference line L11. The error data of the side length can be obtained by subtracting the measurement information obtained by the third side length measuring instrument 33 and the fourth side length measuring instrument 34. Then, the rear sliding roller seat 231, the third side length measuring instrument 33 and the fourth side length measuring instrument 34 are returned to the origin. Then, the floor unit is pushed to the left fixed roller seat 221 by the right sliding roller seat 241, so that the left edge 1012 overlaps with the left reference line L12. The error data of the side length can be obtained by subtracting the measurement information obtained by the fifth side length measuring instrument 35 and the sixth side length measuring instrument 36. Then, the right sliding roller seat 241, the fifth side length measuring instrument 35 and the sixth side length measuring instrument 36 are returned to the origin to facilitate subsequent measurements. For example, consider a floor unit with a standard size of 600x600mm. Before measurement, a sample board with four sides of 600x600mm is zeroed, and then the measurement begins. Taking a floor unit under test as an example, if the measurement information obtained by the third side length measuring device 33 and the fourth side length measuring device 34 are 0.05 and -0.05 respectively, and 0.05-(-0.05)=0.1mm, then the side length of this side of the floor unit under test is 600-0.1=599.9mm. The side length of the other side is measured using the same side length judgment method. For example, a tolerance range of 600x600±0.1mm can be used to determine whether the side length of the floor unit under test is qualified. Both sides must be qualified. This invention ensures the quality of the floor unit shipment. Therefore, before measurement, it is assumed that the floor unit under test is not necessarily square. Consequently, there is a possibility that the left edge 1012 of the floor unit 101 may not be perpendicular to the front edge 1011. If the left edge 1012 of the floor unit 101 is perpendicular to the front edge 1011, then the front edge 1011 and left edge 1012 of the floor unit 101 will overlap with the front reference line L11 and the left reference line L12, respectively. Therefore, the clamping mechanism 2 is designed such that when positioning the floor unit, at least one point on the left edge 1012 of the floor unit 101 overlaps with the left reference line L12, thereby facilitating the measurement of the squareness of the floor unit. The squareness measurement method can be a program code recorded in the controller, which obtains the squareness of the left side edge 1012, rear side edge 1013, and right side edge 1014 of the floor unit 101 based on the measurement results of the first side length measuring device to the sixth side length measuring device 31, 32, 33, 34, 35, and 36. According to this structure, the improved measurement method for the floor unit of the raised floor of the present invention can further include the following steps (S20) to (S22). S20) First, the floor unit is pushed to the front fixed roller seat 211 by the two rear sliding roller seats 231, so that the front edge 1011 overlaps with the front reference line L11. Then, the floor unit is pushed to the left fixed roller seat 221 by the right sliding roller seat 241, so that at least one point on the left edge 1012 overlaps with the left reference line L12 (as shown in Figure 8). S21) The first side length measuring device 31 measures the position of the left edge of the floor unit near the front to obtain a first squareness measurement information. The second side length measuring device 32 measures the position of the left edge of the floor unit near the rear to obtain a second squareness measurement information. The third side length measuring device 33 measures the position of the rear edge of the floor unit near the left side to obtain a third squareness measurement information. The fourth side length measuring device 34 measures the position of the rear edge of the floor unit near the right side to obtain a fourth squareness measurement information. The fifth side length measuring device 35 measures the position of the right edge of the floor unit near the front to obtain a fifth squareness measurement information. The sixth side length measuring device 36 measures the position of the right edge of the floor unit near the rear to obtain a sixth squareness measurement information (as shown in Figure 9). S22) The squareness measurement means obtains the squareness of the left edge 1012 of the floor unit based on the first squareness measurement information, the second squareness measurement information and the front reference line, obtains the squareness of the rear edge 1013 of the floor unit based on the third squareness measurement information, the fourth squareness measurement information and the front reference line, and obtains the squareness of the right edge 1014 of the floor unit based on the fifth squareness measurement information, the sixth squareness measurement information and the front reference line; the clamping mechanism 2 and the first side length measuring device to the sixth side length measuring devices 31, 32, 33, 34, 35, 36 return to the origin (as shown in Figure 3). As described in steps S20) to S22), when measuring the squareness of the floor unit 101, based on the front edge 1011 and the front reference line L11 and the left edge 1012 and the left reference line L12, the squareness of the left edge 1012, the rear edge 1013 and the right edge 1014 of the floor unit 101 relative to the right edge, the front edge and the left edge can be obtained, and thus the test floor unit can be accurately determined as qualified. Furthermore, before measuring the squareness, the standard block (which can be a 60x60 cm floor unit) is first pushed to the front fixed roller seat 211 using the two rear sliding roller seats 231, so that the front edge 1011 overlaps with the front reference line L11. Then, the standard block is pushed to the left fixed roller seat 221 using the right sliding roller seat 241, so that the left edge 1012 overlaps with the left reference line L12 (the standard block is square, so its left edge can overlap with the left reference line. In contrast, the floor unit to be measured later is not necessarily square, so during positioning, at least one point on the left edge of the floor unit overlaps with the left reference line). The first side length measuring device to the sixth side length measuring device is zeroed. Then, the rear sliding roller seat 231, the right sliding roller seat 241, and the first side length measuring device to the sixth side length measuring device 31, 32, 33, 34, 35, 36 are returned to the origin to facilitate the subsequent measurement of the squareness of the floor unit. Next, subtracting the measurement information from the second side length measuring device 32 from the measurement information from the first side length measuring device 31 yields the squareness of the left edge corresponding to the right edge. Subtracting the measurement information from the fourth side length measuring device 34 from the measurement information from the third side length measuring device 33 yields the squareness of the rear edge corresponding to the front edge. Subtracting the measurement information from the sixth side length measuring device 36 from the measurement information from the fifth side length measuring device 35 yields the squareness of the right edge corresponding to the left edge. Furthermore, the present invention may include a squareness determination method, which can determine whether the squareness of the tested floor unit is qualified, requiring that the left edge, rear edge, and right edge all be qualified. Figure 10 is a schematic diagram of the present invention with a second platform and a four-leg height measuring device. The reinforcing ribs within the bottom frame of the floor unit are omitted in Figure 10 for clarity. As shown in Figures 10-11, the present invention may also include a second platform 10; the second platform 10 is located next to the first platform 1, and a four-leg height measuring device 41 may be provided on the second platform 10. In this case, after the floor unit 101 has been measured on the first platform 1, the floor unit 101 can be placed on the second platform 10 to measure the four-leg height of the floor unit. Furthermore, the floor unit 101 may consist of a floor body 1015 and a surface material 1016. The floor body 1015 can be made of materials such as aluminum alloy, while the surface material 1016 can be made of various materials. Since some surface materials 1016 have high elasticity, the floor unit 101 can be placed on the second platform 10 with the surface material 1016 facing down and the corner bottom 1017 facing up to prevent deformation of the surface material 1016, which could affect the accuracy of the four-leg height measurement. As shown in Figures 10-12, the four-leg height measuring device 41 is suspended above the four corners of the floor unit 101 to measure the leg height H1 at the four corners of the floor unit 101, thereby obtaining the leg height measurement value. Furthermore, to facilitate the measurement and replacement of the floor unit 101, the second platform 10 may be further provided with: four cantilever support seats 42, which are located on the second platform 10 and on the outside of the four corners of the floor unit 101; four cantilever arms 43, each having a pivot end 431 and a suspension end 432, with the pivot end 431 of the four cantilever arms 43 rotatably mounted on the four cantilever support seats 42, so that the suspension end 432 of the four cantilever arms 43 can swing between the four corners of the floor unit 101 and the outside of the floor unit 101; four swinging pneumatic cylinders 44, which drive the four cantilever arms 43 to swing respectively; and the four-leg height measuring device 41 is located on the suspension end 432 of the four cantilever arms 43. Alternatively, the four-leg height measuring device 41 can use a laser rangefinder 413 or a displacement meter (not shown in the figure) as the measuring device. The following is an example of the laser rangefinder 413. The four-leg height measuring device 41 has a pneumatic cylinder 411, a fixed base 412 and a laser rangefinder 413. As shown in Figures 13-15, the pneumatic cylinder 411 comprises: a cylinder body 4111 fixed to the suspension end 432 of the cantilever, having an internal pneumatic chamber 41111, and having an upper through hole 41112 communicating with the center of the top of the pneumatic chamber 41111, a lower through hole 41113 communicating with the center of the bottom of the pneumatic chamber 41111, an upper air valve 41114 communicating with the top of the pneumatic chamber 41111, and a lower air valve 41115 communicating with the bottom of the pneumatic chamber 41111; and a rod body 41 12. Inserted between the upper through hole 41112, the air pressure chamber 41111, and the lower through hole 41113 of the cylinder body 4111, a baffle 41121 that will not detach from the air pressure chamber 41111 is provided in the middle section of the rod body 4112. When measuring the floor height, the rod body 4112 moves up and down in the air pressure chamber 41111 according to the floor thickness. A laser rangefinder 41122 is provided at the top of the rod body 4112, and a floor fixing plate 41123 is provided at the bottom of the rod body 4112. When the rod body 4112 of the four-legged height measuring device 41 drives the floor fixing plate 41123 to press down, the floor fixing plate 4123 of the four-legged height measuring device 41 presses against the bottom 1017 of the four corners of the floor unit 101. The fixed base 412 is fixed to the top of the pneumatic cylinder 411 and has a receiving space 4121. The laser rangefinder 41122 is disposed in the receiving space 4121, so that the laser rangefinder 41122 can move up and down in the receiving space 4121 of the fixed base 412. The laser rangefinder 413 is located at the top of the accommodating space 4121 of the fixed base 412 and can measure the distance H2 between it and the laser rangefinder 41122. The four-leg height measuring device 41 can operate in conjunction with the single-leg height measuring means. The leg height measuring means obtains the leg height of the four corners of the floor unit based on the measurement results of the four-leg height measuring device 41. The leg height measuring means can be program code recorded in the controller, which obtains the leg height of the four corners of the floor unit based on the measurement results of the four-leg height measuring device; according to this structure, the improved measurement method of the floor unit of the raised floor of the present invention can further include the following steps S30)~S32). S30) First, place the floor unit with the surface material facing down and the corner bottom facing up. Then, rotate the four cantilever arms 43 on the four cantilever support base 42 so that the four-leg height measuring device 41 is located above the four corners of the floor unit 101 (as shown in Figure 14). S31) The floor fixing piece 41123 of the four-legged height measuring device 41 presses down on the floor unit 101 (as shown in Figure 15). S32) The distance between the laser rangefinder 413 and the laser rangefinder plate 41122 is measured by the laser rangefinder 413 of the four-leg height measuring device 41, and the height of the four corners of the floor unit 101 can be obtained; the floor fixing plate 41123 returns to the origin, and then the four cantilever 43 returns to the origin (as shown in Figure 10). As described in steps S30) to S32), before measuring the leg height, the four-leg height measuring device 41 is placed outside the placement position of the floor unit 101 to facilitate the placement of the floor unit 101; when measuring the leg height, the four-leg height measuring device 41 is placed above the four corners of the floor unit 101 to obtain the leg height of the floor unit; after measuring the leg height, the four-leg height measuring device is returned to its original position to facilitate the replacement of another floor unit. In addition to the aforementioned methods for determining side length and squareness, this invention may also include a method for determining leg height, both of which are program codes recorded in the controller, used to determine whether the tested floor unit meets the tolerance range. Furthermore, this invention may further include a comprehensive determination method to judge whether the tested floor unit is qualified based on its side length and squareness. For example, some tested floor units may happen to form a shape similar to a parallelogram, meaning that both the side length and squareness meet the tolerance range, but the comprehensive determination still does not meet the requirements. As shown in Figure 16, to save manpower, the present invention may further include: a third platform 5, located in front of the first platform 1; a fourth platform 6, located behind the second platform 10; a transport mechanism 7, which further includes: a support frame 71, which erects a transport track 72 above the first platform 1, the second platform 10, the third platform 5, and the fourth platform 6; and at least one gripping mechanism 73, located on the transport track 72, which can move along the transport track 72 and can grip and transport the floor unit 101 between the first platform 1, the second platform 10, the third platform 5, and the fourth platform 6. The side length and squareness of the floor unit are measured on the first platform 1, and the foot height of the floor unit is measured on the second platform 10 with the four corners of the floor unit facing upwards. In this embodiment, two gripping mechanisms 73 are used. When the first gripping mechanism 73 moves the measured floor unit to the second platform 10, the second gripping mechanism 73 simultaneously moves the floor unit to be tested on the third platform 5 to the first platform 1. This not only reduces the standby time of the measurement equipment and thus increases the overall work efficiency, but also facilitates automated operation. As shown in Figure 17, a floor sensor 13 and / or an automatic floor barcode scanner 14 facing the floor unit 101 may also be provided on the first platform 1. The floor sensor 13 is used to activate the aforementioned improved measurement method for the raised floor units only when it senses that a floor unit 101 has been installed on the first platform 1. In addition, a floor code (not shown in the figure) can be set at a predetermined position on the floor unit 101 for each floor unit 101, so as to facilitate the storage of measured information such as side length, squareness, and four-leg height together with the corresponding floor code for subsequent work. The above are embodiments of the present invention, provided for illustrative purposes only, and should not be construed as limiting the scope of the present invention. All variations and designs made in accordance with the listed patent claims should be included within the patent scope of the present invention. 100: Improved measuring device for raised floor units 1: First Platform 2: Clamping mechanism 211: Front fixed roller seat 221: Left side fixed roller seat 23: Rear push mechanism 231: Rear sliding roller seat 24: Right-side propulsion mechanism 241: Right side sliding roller seat 31: First side length measuring device 32: Second side length measuring device 33: Third side length measuring instrument 34: Fourth side length measuring instrument 35: Fifth side length measuring instrument 36: Sixth side length measuring instrument 101: Floor Unit 1011: Front edge 1012: Left edge 1013: Rear edge 1014: Right edge
