Description

Technical Field

[0001] The invention belongs to the technical field of daylighting measurement, and in particular relates to an indoor daylighting measurement device and a measurement method. Background Art

[0002] In order to test the natural lighting conditions of buildings and determine measures to maintain and improve lighting to ensure visual working requirements and energy conservation, GB / T 5699-2017 "Methods for measuring lighting" specifies the test methods for lighting. In this standard, the indoor illuminance measurement points are arranged in a rectangular grid (specified spacing of 0.5m, 1m, 2m, and 4m).

[0003] In actual measurement, when there are fewer measuring points, the instrument can be fixed at the point to be measured for automatic measurement. When there are more measuring points, the operator generally holds a light meter and measures and records each point one by one according to the rectangular layout. For large-area lighting, such as curtain walls and skylights, it is necessary to arrange dozens of points or even more. If the instrument is arranged point by point for automatic measurement, a large number of instruments are required; if the operator measures point by point, the operation process is time-consuming and laborious. At the same time, considering the interference of indoor furnishings and operators on the light receiver, the accuracy of the handheld light meter measurement method is limited. Summary of the invention

[0004] The invention provides an indoor lighting measurement device and a measurement method, the purpose of which is to solve the shortcomings of the prior art and to be able to measure the indoor lighting of large spaces and irregular buildings.

[0005] The technical solution adopted by the present invention to solve its technical problem is:

[0006] An indoor lighting measurement device comprises: a vertical lifting support rod connected to a base below and a central platform above;

[0007] The central platform is a regular octagonal platform, and each of the eight sides is connected to a telescopic measuring arm, and the adjacent telescopic measuring arms are at an angle of 45 degrees.

[0008] The central measuring disc is pivoted above the central platform;

[0009] The two ends of the support rod are respectively hinged on the peripheral measuring plate and the telescopic measuring arm;

[0010] Illuminance sensors are provided at the exact center of the central measuring disk and the peripheral measuring disk.

[0011] A laser rangefinder is built into the same half area of ​​one side of each measuring disc; and the side of each peripheral measuring disc containing the laser rangefinder is arranged facing the central platform.

[0012] Travel wheels are installed under the base.

[0013] The central measuring disk and the peripheral measuring disk are regular octagonal tables of the same size.

[0014] The indoor lighting measurement method using the indoor lighting measurement device comprises the following steps:

[0015] a: Indoor measurement area mapping: Place the device indoors, rotate the central measuring disk, and use its laser rangefinder to measure the indoor area to determine the boundary of the area to be measured;

[0016] b: Grid division: including:

[0017] b1: Select the measuring point interval;

[0018] b2: divide the measuring points into grids at the selected measuring point interval and complete the point arrangement;

[0019] b3: Determine whether the distance between the surrounding measuring points and the boundary meets the specification requirements. If not, repeat b1: Select the measuring point interval;

[0020] c: Determination of basic points and their subsidiary measuring points: Determine each basic measuring point and its subsidiary measuring points;

[0021] d: Measurement route planning: mark the location coordinates of basic measurement points and plan the measurement route;

[0022] e: Device adjustment: adjust the horizontal height to the level required by the specification by lifting and lowering the vertical lifting support rod, adjust the distance between measuring points to the selected measuring point interval in the above step b1 by extending and retracting the telescopic measuring arm in sections, and adjust the peripheral measuring disk to the same level as the central measuring disk by lifting and lowering the supporting rod;

[0023] g: Start measuring: The illumination sensors of the central measuring disk and the peripheral measuring disks perform lighting measurement;

[0024] h: fold the telescopic measuring arm;

[0025] i: proceed to the next basic point;

[0026] j: Adjust the device and repeat the operation in e;

[0027] k: Continue measuring and repeat the operation of g;

[0028] l: Repeat steps h, i, j, and k until all measuring points are measured.

[0029] Further, the step e comprises:

[0030] The central measuring disk and the peripheral measuring disk rangefinders perform relative measurement, and the peripheral measuring disk is fine-tuned. When the values ​​of the two rangefinders are consistent, it indicates that the peripheral measuring disk and the central measuring disk are at the same level.

[0031] Beneficial effects:

[0032] 1: The present invention provides a device that can measure indoor lighting at multiple points simultaneously, and can measure up to 9 points at a time, which greatly improves the efficiency of indoor lighting testing.

[0033] 2: The present invention can adapt to different measurement point location layouts, reduce the impact of indoor furnishings, and adapt to irregular indoor buildings through the setting of basic points and their attached points, measurement path planning, and the setting of retractable and telescopic measuring arms.

[0034] 3: The setting of the support rod of the present invention eliminates the influence of the deflection of the end of the telescopic measuring arm. By using the corresponding measurement of two laser rangefinders arranged opposite to each other, the measuring tray can be adjusted to the level easily and quickly while ensuring the measuring interval.

[0035] Therefore, under the framework of GB / T 5699-2017, the present invention can conveniently and quickly measure indoor lighting in large spaces and irregular buildings. BRIEF DESCRIPTION OF THE DRAWINGS

[0048] The traveling mechanism 2 is composed of a base 201 and traveling wheels 202 installed below the base 201 .

[0049] The measuring mechanism includes a central measuring disk 301 and a peripheral measuring disk 302 .

[0050] The vertical lifting support rod 101 is vertically connected to the base 201 below and the central platform 102 above. The vertical lifting support rod 101 can be raised or lowered by the mechanism of the prior art to adapt to the standard surface height of different types of building lighting measurement.

[0051] The central platform 102 is a regular octagonal platform, and each of the eight sides is connected to a telescopic measuring arm 103, and adjacent telescopic measuring arms 103 are at an angle of 45 degrees. The telescopic measuring arms 103 can be segmented and telescopic with existing technical mechanisms to facilitate the arrangement of different measuring point spacings.

[0052] The central measuring disk 301 and the peripheral measuring disk 302 are regular octagonal tables of the same size.

[0053] The central measuring disk 301 is pivoted directly above the central platform 102 , so it can rotate relative to the central platform 102 .

[0054] Both ends of the support rod 104 are hinged to the peripheral measuring disk 302 and the telescopic measuring arm 103 respectively.

[0055] like Figure 1 , Figure 2 , Figure 3 As shown:

[0056] The exact centers of the central measuring disk 301 and the peripheral measuring disk 302 are both illuminance sensors 303 .

[0057] A laser distance meter 304 is built into the same half of one side of the measuring disk, for example Figure 3 The central measuring disk 301 has a laser rangefinder 304 built into the left half of one side thereof. Similarly, the peripheral measuring disk 302 has a laser rangefinder 304 built into the left half of one side thereof.

[0058] The side of each peripheral measurement disk 302 containing the laser rangefinder 304 is arranged facing the central platform 102 .

[0059] Indoor lighting measurement method using the above-mentioned indoor lighting measurement device:

[0060] The steps include:

[0061] a: Surveying and mapping of the indoor area to be measured; b: Grid division; c: Determination of basic points and their subsidiary points; d: Determination of the measurement route; e: Proceed to the first basic point; f: Adjustment of the device; g: Start measurement; h: Folding in the telescopic measuring arm; i: Proceed to the next basic point; j: Adjustment of the device; k: Continue measurement; l: Repeat operations h, i, j, k until all measurement points are measured.

[0062] a: Indoor measurement area mapping: The device of the present invention is placed indoors, the central measuring disk 301 rotates, and the laser rangefinder 304 measures the indoor measurement area to be measured, thereby determining the boundary to be measured;

[0063] b: Grid division: including:

[0064] b1: Select the measuring point interval;

[0065] b2: divide the measuring points into grids at the selected measuring point interval and complete the point arrangement;

[0066] b3: Determine whether the distance between the surrounding measuring points and the boundary meets the specification requirements. If not, repeat b1: Select the measuring point interval;

[0067] c: Determination of basic points and their subsidiary measuring points: Determine each basic measuring point and its subsidiary measuring points;

[0068] d: Measurement route planning: mark the location coordinates of basic measurement points and plan the measurement route;

[0069] e: Device adjustment: adjust the horizontal height to the level required by the specification by lifting and lowering the vertical lifting support rod 101, adjust the measuring point spacing to the selected measuring point spacing in the above step b1 by segmented extension and retraction of the telescopic measuring arm 103, and adjust the peripheral measuring disk 302 to the same horizontal state as the central measuring disk 301 by lifting and lowering the supporting rod 104.

[0070] like Figure 4 , Figure 5 As shown:

[0071] The rangefinders of the central measuring disk 301 and the peripheral measuring disk 302 perform relative measurement. Since the laser rangefinder 304 of the central measuring disk 301 is in the left half area, and the laser rangefinder 304 of the peripheral measuring disk 302 is in the right half area, when the side of the central measuring disk 301 with the laser rangefinder 304 is opposite to the side of the peripheral measuring disk 302 with the laser rangefinder 304, the laser rangefinder 304 of the central measuring disk 301 measures the right half area of ​​the peripheral measuring disk 302 without the laser rangefinder 304, and the laser rangefinder 304 of the peripheral measuring disk 302 measures the right half area of ​​the central measuring disk 301 without the laser rangefinder 304.

[0072] The peripheral measuring disk 302 is fine-tuned. When the values ​​of the two distance meters are consistent, it indicates that the peripheral measuring disk 302 and the central measuring disk 301 are at the same level.

[0073] g: Start measuring: the illumination sensors 303 of the central measuring disk 301 and the peripheral measuring disk 302 perform lighting measurement;

[0074] h: folding the telescopic measuring arm 103;

[0075] i: proceed to the next basic point;

[0076] j: Adjust the device and repeat the operation in e;

[0077] k: Continue measuring and repeat the operation of g;

[0078] l: Repeat steps h, i, j, and k until all measuring points are measured.

[0079] like Figure 6 As shown, it is an embodiment of the present invention used in an irregular space:

[0080] a: Indoor measurement area mapping: The device of the present invention is placed indoors, the central measuring disk 301 rotates, and the laser rangefinder 304 measures the indoor measurement area to be measured, thereby determining the boundary to be measured;

[0081] b: Grid division: including:

[0082] b1: Select the measuring point interval;

[0083] b2: divide the measuring points into grids at the selected measuring point interval and complete the point arrangement;

[0084] b3: Determine whether the distance between the surrounding measuring points and the boundary meets the specification requirements. If not, repeat b1: Select the measuring point interval;

[0085] Finally, it was decided Figure 6 26 measuring points shown;

[0086] c: Determination of basic points and their subsidiary measuring points: Determine each basic measuring point and its subsidiary measuring points;

[0087] like Figure 6 , determine A, B, C, and D in the circle as basic measuring points, that is, the test points of the illumination sensor 303 of the central measuring disk 301 of the device, and A, B, C, and D in the box as subsidiary measuring points, that is, the test points of the illumination sensor 303 of the peripheral measuring disk 302 of the device. In this way, point A in a circle is used as a basic measuring point, with 8 subsidiary measuring points; point B in a circle is used as a basic measuring point, with 5 subsidiary measuring points; point C in a circle is used as a basic measuring point, with 5 subsidiary measuring points; point D in a circle is used as a basic measuring point, with 4 subsidiary measuring points.

[0088] d: Measurement route planning: mark the location coordinates of basic measurement points and plan the measurement route:

[0089] The machine moves along the path of the basic points ABCD, as shown by the arrows, and by controlling the extension and retraction of the telescopic measuring arm, 9 points, 6 points, 6 points, and 5 points are measured at ABCD respectively. In this way, all points in the area to be measured can be measured.

[0090] e: Device adjustment: move the base 201 to point A in the circle; adjust the horizontal height to the level required by the specification by lifting and lowering the vertical lifting support rod 101, adjust the measuring point spacing to the selected measuring point spacing in the above step b1 by segmented extension and retraction of the telescopic measuring arm 103, and adjust the peripheral measuring disk 302 to the same horizontal state as the central measuring disk 301 by lifting and lowering the supporting rod 104.

[0091] like Figure 4 , Figure 5 As shown:

[0092] The rangefinders of the central measuring disk 301 and the peripheral measuring disk 302 perform relative measurement. Since the laser rangefinder 304 of the central measuring disk 301 is in the left half area, and the laser rangefinder 304 of the peripheral measuring disk 302 is in the right half area, when the side of the central measuring disk 301 with the laser rangefinder 304 is opposite to the side of the peripheral measuring disk 302 with the laser rangefinder 304, the laser rangefinder 304 of the central measuring disk 301 measures the right half area of ​​the peripheral measuring disk 302 without the laser rangefinder 304, and the laser rangefinder 304 of the peripheral measuring disk 302 measures the right half area of ​​the central measuring disk 301 without the laser rangefinder 304.

[0093] The peripheral measuring disk 302 is fine-tuned. When the values ​​of the two distance meters are consistent, it indicates that the peripheral measuring disk 302 and the central measuring disk 301 are at the same level.

[0094] g: Start measuring: the illumination sensors 303 of the central measuring disk 301 and the peripheral measuring disk 302 perform lighting measurement at 9 points A;
