Description

Technical Field

[0001] The present invention relates to the field of illuminance technology testing, and particularly to a street lamp illuminance measuring device and a control method thereof. Background Art

[0002] The measurement of street lamp illuminance is generally carried out according to two methods, namely central point layout and four-corner point layout, in the national standard "Illumination Measurement Method" (GB / T 5700 - 2008). In the traditional manual measurement method, the area is first divided and points are laid out on the road surface, and the illuminance is measured point by point. Finally, the test results are summarized. Since the number of illuminance measurement points is generally dozens, it takes at least 1 to 2 hours to complete one test, resulting in low test efficiency. In addition, the large time span of point-by-point measurement causes large measurement errors.

[0003] In the related art, an illuminance meter or a luminance meter is installed on a vehicle or a trolley. By moving the vehicle or the trolley at a certain speed, the illuminance or luminance of the road surface can be quickly collected. This method shortens the measurement time, but the test standard requires that the illuminance meter should be close to the road surface, and this method is difficult to meet the requirements. Moreover, it is difficult to ensure that the vehicle travels along the established track during driving, and it is easy to deviate from the route, resulting in measurement errors.

[0004] In the related art, it is proposed to use the roadbed as a reference, and an infrared sensor is used to detect the distance from the roadbed vehicle to ensure the driving path. However, the roadbed often has gaps or is blocked by greenery, garbage, etc., which block the infrared sensor, resulting in the inability to ensure that the vehicle travels along the established path.

[0037] The embodiments described in the embodiments of this application should not be regarded as limitations to this application. All other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of this application.

[0038] In the following description, reference is made to "some embodiments", which describe subsets of all possible embodiments. However, it can be understood that "some embodiments" can be the same subset or different subsets of all possible embodiments, and can be combined with each other without conflict.

[0039] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those of ordinary skill in the technical field to which this application belongs. The terms used herein are only for the purpose of describing the embodiments of this application and are not intended to limit this application.

[0040] The embodiment of the present invention provides a street lamp illuminance measuring device. Refer to Figure 1 , including: two tracks 110, a running mechanism 120, a plurality of illuminometers 130, and a processing component (not shown in the figure). The running mechanism 120 includes a crossbar 122, a driving component (not shown in the figure), and two pulleys 121. The two pulleys 121 are respectively arranged at both ends of the crossbar 122 through the driving component. The two pulleys 121 of the running mechanism 120 are respectively placed on the two tracks 110, so that the crossbar 122 and the two tracks 110 form an H shape. The running mechanism further includes a connecting component for connecting the illuminometers 130 and arranging the illuminometers 130 on the running mechanism. The connecting component includes a fixing ring 123 and a connecting rod 124. A plurality of fixing rings 123 are sleeved on the crossbar. Two connecting rods 124 are connected to each fixing ring 123. The first end of the connecting rod 124 is connected to the fixing ring 123, and the second end of the connecting rod 124 is connected to the fixing ring 123, thereby forming a structure in which the illuminometers 130 are symmetrically arranged on both sides of the crossbar 122. This structure of arranging the illuminometers 130 on both sides of the crossbar 122 can improve the acquisition efficiency.

[0041] Refer to Figure 2, the central point layout method is adopted to test the street lamp illuminance. The measurement area is set between street lamp 1 and street lamp 2. The measurement area is equally divided into 16 * 7 small areas. The center of each small area is a data collection point, with a total of 16 * 7 data collection points. The 7 data collection points in the first column are aligned with street lamp 1, and the 7 data collection points in the last column are aligned with street lamp 2. Two tracks are respectively placed on both sides of the measurement area. Initially, align the crossbar with dashed line 1 and adjust the position of the fixed ring on the crossbar so that the illuminometer is located at the data collection point. During operation, the processing component controls the movement of the operating mechanism and controls the illuminometer to collect data simultaneously when the crossbar moves to the positions of dashed line 1, dashed line 2, dashed line 3, dashed line 4, dashed line 5, dashed line 6, dashed line 7, and dashed line 8. The processing component calculates the average illuminance according to the following formula:

[0042]

[0043] Among them, n1 represents the number of small areas in the row of the measurement area, n2 represents the number of small square areas in the column of the measurement area, and E i represents the measured illuminance at the i-th data collection point, and the illuminance unit is lux. In this embodiment, the value of n1 is substituted with 16, and the value of n2 is substituted with 7.

[0044] Similarly, referring to Figure 3 , the four-corner point layout method can also be used to test the street lamp illuminance. The measurement area is set between street lamp 1 and street lamp 2. The measurement area is equally divided into 16 * 7 small areas. A data collection point is set at the vertex of each small area, with a total of 17 * 8 data collection points. The 8 data collection points in the first column are aligned with street lamp 1, and the 8 data collection points in the last column are aligned with street lamp 2. Two tracks are respectively placed on both sides of the measurement area. Initially, align the crossbar with dashed line 1 and adjust the position of the fixed ring on the crossbar so that the illuminometer is located at the data collection point. During operation, the processing component controls the movement of the operating mechanism and controls the illuminometer to collect data simultaneously when the crossbar moves to the positions of dashed line 1, dashed line 2, dashed line 3, dashed line 4, dashed line 5, dashed line 6, dashed line 7, dashed line 8, and dashed line 9. The processing component calculates the average illuminance according to the following formula:

[0045]

[0046] Among them, n1 represents the number of small areas in the row of the measurement area, n2 represents the number of small square areas in the column of the measurement area, and E θ is the illuminance measured at the four vertices of the measurement area, E0 is the illuminance measured at the data collection points on the four outer sides except the four vertices of the measurement area, and E is the illuminance measured at each data collection point inside the four outer sides. In this embodiment, the value of n1 is substituted with 16, and the value of n2 is substituted with 7.

[0047] It should be noted that the processing component will automatically identify the in-field points, sideline points, and corner points to quickly complete data analysis and calculation.

[0048] It should be noted that the illuminometer can also be connected to the crossbar without the connecting component of the fixing ring and the connecting rod. The illuminometer can also be directly arranged at equal intervals on the upper surface of the crossbar. Symmetrically distributed illuminometers can be arranged on both sides of the crossbar at different times, or a row of illuminometers can be arranged on only one side of the crossbar. When the illuminometer is directly arranged at equal intervals on the upper surface of the crossbar, pulleys with a small diameter can be used to minimize the distance between the crossbar and the ground, thereby reducing the distance between the illuminometer and the ground, which is more in line with the measurement standard. It can be understood that with different setting methods of the illuminometer and the crossbar, the initial position of the crossbar in the measurement area is also different, and the position of the illuminometer when collecting data during the movement is also different.

[0049] According to some specific embodiments of the present invention, referring to Figure 4 , the fixing ring 123 is provided with a tightening mechanism 210. The tightening mechanism 210 can be a combination of a nut and a bolt, or a combination of a bayonet and a card slot. When the tightening mechanism 210 is opened, the position of the fixing ring 123 on the crossbar can be adjusted arbitrarily. When the tightening mechanism 210 is closed, the fixing ring 123 can be fixed on the crossbar, so that the illuminometer 130 will not shake in the horizontal direction, thereby improving the credibility of the measurement result. A rotating component 220 is arranged on the connecting rod 124. The rotating component 220 can only make the connecting rod rotate in the up-and-down direction relative to the ground. The connecting rod 124 is connected to the fixing ring 123 and the bottom support 230 through the rotating component 220. A roller 240 is arranged at the bottom of the bottom support 230. The roller 240 can be retracted into the bottom support 230. When the illuminometer 130 moves to the data collection point, the roller 240 is retracted into the bottom support 230, so that the illuminometer 130 is closer to the road surface, and the measured illuminance value is closer to the road surface illuminance. After the illuminometer 130 finishes collecting data, the roller 240 lifts the bottom support 230 and slides to the next data collection point driven by the crossbar.

[0050] It should be noted that the connecting rod can adopt a telescopic rod such as a lead screw with an adjustable length to adjust the horizontal distance between the illuminometer and the crossbar to adapt to different point layout methods.

[0051] According to some specific embodiments of the present invention, referring to Figure 5 , the middle of the fixing ring 123 is made of a transparent material and is drawn with a dotted line. This dotted line is on the same straight line as the central axis of the connecting rod. Scale lines are arranged on the crossbar 122. When adjusting the position of the fixing ring 123 on the crossbar 122, the scale lines on the crossbar 122 and the dotted line on the fixing ring 123 can be referred to, so as to accurately and quickly adjust the position of the illuminometer.

[0052] According to some specific embodiments of the present invention, referring to Figure 6, the shape of the track 110 can be convex. Correspondingly, the edge of the pulley 121 is concave and fits with the track 110. Refer to Figure 7 , the shape of the track 110 can be concave. Correspondingly, there is no restriction on the edge of the pulley 121. The pulley 121 can be directly placed into the track 110. The function of the track 110 is to physically limit the movement path of the pulley 121, so that the crossbar can move in the measurement area without deviating from the measurement area.

[0053] It should be noted that, without affecting the sliding of the pulley 121 on the track 110, a pulley 121 with a small diameter can be used to reduce the height of the crossbar from the road surface, so that the shadow of the pulley 121 does not block the illuminometer, and the diameters of the two pulleys are kept the same.

[0054] According to some specific embodiments of the present invention, the illuminometer is built-in with a wireless transmission module. The wireless transmission module can adopt methods such as Bluetooth and wifi. The illuminometer is connected to the processing component through wireless transmission. The processing component is responsible for analyzing the data collected by the illuminometer. Its carrier can be a notebook or a mobile phone, etc. In addition, the processing component can also control the moving speed and other moving conditions of the operating mechanism, as well as control the data collection time of the illuminometer.

[0055] An embodiment of the present invention also provides a control method for a street lamp illuminance measurement device, which is applied to the street lamp illuminance measurement device in the above embodiment. The control method of the street lamp illuminance measurement device includes but is not limited to step 810 and step 820:

[0056] Step 810, control the movement on the track of the operating mechanism.

[0057] Step 820, when the illuminometer on the operating mechanism moves to the data collection point, control the illuminometer to collect data.

[0058] In some embodiments, refer to Figure 2 and Figure 3 , the measurement personnel plan the length of the rectangular measurement area as L and the width as B according to the actual situation. After equally dividing the length L, the number of columns obtained is n1. After equally dividing the width B, the number of rows obtained is n2. At this time, the measurement area is divided into n1×n2 small areas with equal areas. The divided small areas are generally close to squares. Then the measurement personnel can choose the center point layout method or the four-corner point layout method to arrange the data collection points.

[0059] Refer to Figure 2, the surveyor adopts the point layout method of the central point layout. The placement direction of the track is parallel to the connection line between street lamp 1 and street lamp 2. The two tracks sandwich the measurement area in the middle. The crossbar in the street lamp illuminance measurement device is sleeved with n2 illuminometers. Adjust the length of the connecting rod so that the horizontal distance from the center of each illuminometer to the central axis of the crossbar is (L / n1) / 2. Adjust the crossbar to the position of dotted line 1, and then adjust the position of the fixing ring on the crossbar so that each illuminometer coincides with the data acquisition points on both sides of dotted line 1. The distance between each fixing ring is B / n2. The processing component in the street lamp illuminance measurement device can be connected to the upper computer. The surveyor inputs the length L of the measurement area and the number of columns n1 divided into the processing component through the upper computer. The processing component can obtain the first distance between the data sampling points according to the formula L / n1. Of course, the surveyor can also directly input the first distance between the sampling points into the upper computer. After that, the processing component controls the driving component in the operating mechanism to work so that the pulley moves on the track. At the same time when the driving component works, it controls the illuminometers on both sides of the crossbar to collect data. Then the processing component determines the second distance that the operating mechanism moves according to the diameter of the pulley and the number of turns of the pulley movement. When the second distance is an even multiple of the first distance during the pulley movement, it can be determined that the illuminometer moves to the next data acquisition point, and then it controls all the illuminometers to collect data at the same time. When n1 is an even number, the number of times each illuminometer collects data is n1 / 2, otherwise it is the rounded integer of n1 / 2. After the number of times each illuminometer collects data reaches the calculated number of collection times, the processing component controls the driving mechanism to stop working.

[0060] Refer to Figure 3, surveyors can also adopt the layout method of the four-corner layout method. The placement direction of the track is parallel to the connection line between street lamp 1 and street lamp 2. The two tracks sandwich the measurement area in the middle. There are n2 + 1 illuminometers sleeved on the cross bar of the street lamp illuminance measurement device. Adjust the length of the connecting rod so that the horizontal distance from the center of each illuminometer to the central axis of the cross bar is (L / n1) / 2. Adjust the cross bar to the position of dotted line 1, and then adjust the position of the fixing ring on the cross bar so that each illuminometer coincides with the data acquisition points on both sides of dotted line 1. The distance between each fixing ring is B / n2. The processing component in the street lamp illuminance measurement device can be connected to the upper computer. The surveyor inputs the length L of the measurement area and the number of columns n1 divided into the processing component through the upper computer. The processing component can obtain the first distance between the data sampling points according to the formula L / n1. Of course, the surveyor can also directly input the first distance between the sampling points into the upper computer. Then the processing component controls the driving component in the operating mechanism to work so that the pulley moves on the track. At the same time when the driving component works, it controls the illuminometers on both sides of the cross bar to collect data. Then the processing component determines the second distance that the operating mechanism moves according to the diameter of the pulley and the number of turns of the pulley movement. When the second distance is an even multiple of the first distance during the pulley movement, it can be determined that the illuminometer moves to the next data acquisition point, and then it controls all the illuminometers to collect data at the same time. When n1 is an even number, the number of times the cross bar moves is n1 / 2 + 1, otherwise it is the integer obtained by rounding n1 / 2. After the number of times each illuminometer collects data reaches the calculated number of acquisitions, the processing component controls the driving mechanism to stop working.

[0061] It should be noted that since the illuminometer adopts a symmetric distribution structure with the cross bar, when the second distance is an even multiple of the first distance, it is determined that the illuminometer moves to the next data acquisition point. When the illuminometers are only distributed on one side of the cross bar or a row of illuminometers are directly arranged on the surface of the cross bar, as long as the second distance is a multiple of the first distance, it is determined that the illuminometer moves to the next data acquisition point. It can be understood that the calculation results of the first distance and the second distance may be infinite decimals. Therefore, the multiple described here is any value within a threshold range.

[0062] It should be noted that some street lamps may be set in the turning area of the road. Then the measurement area can be set as an arc, the track is correspondingly set as an arc, and the control method is adjusted accordingly, that is, when the wheel reaches the arc position, the speeds of the inner and outer wheels will be different, and the calculation of the first distance and the second distance also needs to be calculated according to the distribution of the data acquisition points on the inner and outer sides and the speed of the pulley respectively.

[0063] In the street lamp illuminance measuring device according to the embodiment of the present invention, a physical way of using a track is adopted to define the movement path of the operating mechanism, which will not be affected by obstacles on the road surface and deviate from the measurement area, reducing the probability of the illuminance meter deviating from the data acquisition point, thereby improving the measurement accuracy of the street lamp illuminance. Multiple illuminance meters are arranged on the operating mechanism, which can improve the efficiency of data acquisition. Using a base to place the illuminance meter, and connecting the cross bar with the base to drive the illuminance meter to move can reduce the height of the illuminance meter, which is more in line with the measurement requirements. The street lamp illuminance measuring device does not need to use a distance sensor to detect the moving distance of the operating mechanism, but directly calculates the moving distance of the operating mechanism according to the number of rotation turns of the pulley by the processing component, so that the illuminance meter can accurately reach the data acquisition point to complete data acquisition. The calculation of the moving distance is also not affected by road surface obstacles and does not require a distance sensor to be set, reducing the device cost.

[0064] The above is a specific description of the preferred embodiment of the present invention. However, the present invention is not limited to the above embodiments. Those skilled in the art can make various equivalent deformations or substitutions without departing from the spirit of the present invention, and these equivalent deformations or substitutions are all included in the scope defined by the claims of the present invention.
