[0027] Example

[0028] The specific embodiments of the present invention are as follows Figures 1 to 5 As shown, a multifunctional indoor building measurement method comprises a group of first distance measuring sensors arranged in parallel along a straight line to form a distance measuring scanning array. The distance measuring scanning array is translated in a direction parallel to the building plane. During the process, each first distance measuring sensor obtains the distance between the first distance measuring sensor and the building plane to be measured as the first distance data. At the same time, the real-time position of the translation of the distance measuring scanning array is monitored by the second distance measuring sensor and the second distance data is obtained. The angle data of the distance measuring scanning array relative to the horizontal plane is obtained by the angle measuring instrument. Then, the first distance data, the second distance data, and the angle data are collected by the controller.

[0029] The first distance measuring sensors are oriented in parallel and are arranged at equal intervals, and the orientation of the first distance measuring sensors is perpendicular to the arrangement direction of the first distance measuring sensors.

[0030] The arrangement direction of each first ranging sensor in the ranging scanning array is perpendicular to the translation direction of the ranging scanning array, and the orientation of the first ranging sensor is perpendicular to the translation direction of the ranging scanning array.

[0031] In this embodiment, the first distance measuring sensor is the first laser distance sensor 2. The second distance measuring sensor is the second laser distance sensor 7, which is relatively fixed to the ground. The orientation of the second laser distance sensor 7 is parallel to the translation direction of the distance measuring scanning array, and a target relatively fixed thereto is provided on one side of the distance measuring scanning array, and the second laser distance sensor 7 faces the target. When the distance measuring scanning array translates, the second laser distance sensor 7 measures the real-time position of the target and uses it as the second distance data.

[0032] In addition to laser distance sensors, the first distance measuring sensor and the second distance measuring sensor may also be other types of distance sensors.

[0033] Before measuring the building plane, the ranging scanning array is rotated by a certain angle relative to the horizontal plane so that the ranging point of each first ranging sensor on the ranging scanning array can fall on the building plane to be measured. The rotation axis of the ranging scanning array is parallel to the translation direction of the ranging scanning array.

[0034] When the ranging scanning array is translated, one end of the ranging scanning array is guided by the guide rail 65, and the other end of the ranging scanning array is supported on the plane of the building to be measured by the running wheels 9.

[0035] The angle measuring instrument is a gyroscope 3, and the positions of the gyroscope 3 and the distance measuring scanning array are relatively fixed.

[0036] The present measurement method is implemented by a multifunctional indoor building measurement instrument, which includes a translation distance measurement mechanism 6, which is connected to a mounting frame 1 through a rotating support 5, and a plurality of first laser distance sensors 2 arranged along a straight line are arranged on the mounting frame 1, and the arrangement direction of each first laser distance sensor 2 is perpendicular to the moving direction of the translation distance measurement mechanism 6. A gyroscope 3 is also provided on the mounting frame 1, and the first laser distance sensor 2, the translation distance measurement mechanism 6 and the gyroscope 3 are all electrically connected to a controller.

[0037] The rotating shaft of the rotating support 5 can be a bolt, and the angle thereof can be locked by tightening the bolt and the nut.

[0038] The mounting frame 1 is provided with a sensor guard plate 4, which is located on both sides of the first laser distance sensor 2. In this embodiment, a strip of U-shaped channel steel is installed on the mounting frame 1, the first laser distance sensor 2 is located on the inner side of the U-shaped channel steel, and the two side walls of the U-shaped channel steel constitute the sensor guard plate 4. The sensor guard plate 4 can reduce the probability of the first laser distance sensor being hit and causing a decrease in measurement accuracy, thereby ensuring the stability of performance.

[0039] In this embodiment, the mounting frame 1 adopts a straight strip profile structure. The mounting frame 1 includes at least two mounting frame modules 11 that can be folded with each other, and each mounting frame module 11 is provided with a first laser distance sensor 2 and a gyroscope 3. In this embodiment, the mounting frame 1 is composed of two mounting frame modules 11, one end of which is rotatably connected to the translation distance measurement mechanism 6 through a rotating support 5. One side of the adjacent mounting frame modules 11 is hinged by a hinge 12, and the other side is connected by a locking plate 13. Specifically, both ends of the locking plate 13 are provided with through holes for screws to pass through, and the screws at both ends pass through the through holes at both ends of the locking plate 13 and are threadedly connected to the corresponding mounting frame modules 11, thereby locking the relative positions of the adjacent mounting frame modules 11. The foldable mounting frame modules 11 make the measuring instrument convenient to carry and store, and when unfolded, the relative positions of the adjacent mounting frame modules can be locked by the locking plate to prevent shaking.

[0040] The first laser distance sensors 2 are oriented in parallel and are arranged at equal intervals.

[0041] One end of the mounting frame 1 away from the translation distance measuring mechanism 6 is rotatably connected with a running wheel 9. In this embodiment, the rotation axis of the running wheel 9 coincides with the center line of the mounting frame 1. The running wheel 9 is used to contact the wall or the ground, and plays a role in supporting and stabilizing the mounting frame 1.

[0042] Each mounting frame module 11 of the mounting frame 1 is provided with a handle 8. The handle 8 is located at one side of the mounting frame module 11. By operating the handle, it is convenient for personnel to move the mounting frame 1.

[0043] The translation distance measurement mechanism 6 includes a guide rail 65 and a slider 63 that slide with each other, and the slider 63 and the rotating support 5 are both installed on the moving seat 61. A second laser distance sensor 7 is provided at one end of the guide rail 65, and the second laser distance sensor 7 is electrically connected to the controller. A target is provided on the moving seat 61, and the laser emission end of the second laser distance sensor 7 faces the target. When the moving seat 61 moves relative to the guide rail 65, the position data of the moving seat 61 in the X-axis direction can be obtained through the second laser distance sensor 7.

[0044] The translation distance measuring mechanism 6 also includes a horizontally arranged support plate 64, and the second laser distance sensor 7 is connected to the support plate 64. The guide rail 65 is installed on the upper surface of the support plate 64, and at least one pair of two rollers 62 are rotatably connected to the moving seat 61, and the rollers 62 are pressed on the support plate 64. A plurality of support legs 66 are connected to the bottom of the support plate 64. The height of each support leg 66 can be adjusted separately to ensure that the guide rail 65 is arranged horizontally.

[0045] When in use, the translation distance measuring mechanism 6 is first placed on the ground, and after adjusting the horizontality of the guide rail 65, the angle of the mounting frame 1 relative to the horizontal plane is adjusted by rotating the support 5 according to the index to be measured, so that the distance measuring point of each first laser distance sensor 2 on the distance measuring scanning array can fall on the plane of the building to be measured (wall or ground). When it is necessary to measure the wall, the guide rail 65 is set to be parallel to the bottom of the wall, and the running wheel 9 is placed against the wall. Figure 4 When the ground needs to be measured, the walking wheel 9 is pressed on the ground, as shown in FIG. Figure 5 As shown. Start each laser distance sensor, and then let the mobile seat 61 drive the mounting frame 1 to move horizontally. During this process, each first laser distance sensor 2 continuously measures the distance data between it and the wall / ground and uses it as the first distance data, while the second laser distance sensor 7 continuously measures the moving distance of the mobile seat 61 and uses it as the second distance data. The gyroscope 3 obtains the angle data of the distance measurement scanning array relative to the horizontal plane in real time. The controller collects the data of each laser distance sensor and the gyroscope, and uploads the data to the software for processing and calculation.

[0046] The controller can be connected to a smart terminal such as a computer or a mobile phone via a data cable, or it can be connected to the smart terminal via wireless network communication. After the smart terminal receives the data, it can process it through software.

[0047] The measurement process only requires one person to operate, which can reduce the number of measurement personnel and has low requirements on the professional measurement level of personnel, which is conducive to reducing labor costs; the structure is simple and the production cost is low, which can be controlled below 10,000 yuan; the measurement accuracy is high and the probability of measurement error is low; it can realize simultaneous measurement of multiple indicators, which is conducive to the subsequent simultaneous calculation of corresponding data through software, and the measurement efficiency is high.

[0048] The present invention has been described above in conjunction with the best embodiments, but the present invention is not limited to the embodiments disclosed above, but should cover various modifications and equivalent combinations based on the essence of the present invention.
