Description
Technical Field
[0001] This application relates to the technical field of photometric detection equipment, and in particular to an indoor light detection device. Background Technology
[0002] In the construction industry, indoor luminosity is a crucial indicator of building lighting quality, directly impacting people's visual experience, work efficiency, and physical and mental health. With the continuous development of the construction industry, the demand for accurate indoor luminosity measurement is increasing. Accurate luminosity measurement provides a scientific basis for building design, optimizes building lighting layout, improves energy efficiency, and helps ensure the quality of the living and working environment for indoor occupants. For example, in office buildings, appropriate luminosity can reduce employee visual fatigue and improve work efficiency; in residential buildings, good lighting can create a comfortable living atmosphere.
[0003] In traditional indoor photometric testing, the common method is for manual, handheld photometers to perform single-point measurements. The testing personnel need to carry the instrument to different locations indoors to take measurements one by one, recording the photometric data at each point. Another common approach is to install multiple photometric sensors at fixed locations indoors, transmitting data to a monitoring center via wired or wireless means. Yet another method uses portable photometric testing equipment for mobile testing indoors, but this requires manual operation and data recording by the testing personnel. While these methods can meet the needs of indoor photometric testing to some extent, they have some problems in practical applications.
[0004] Traditional indoor photometric measurement methods have significant drawbacks. Manual, handheld measurement is inefficient, requiring substantial manpower and time, and the results are easily affected by human factors, making it difficult to guarantee accuracy and consistency. While fixed-location sensor installation allows for real-time monitoring, the limited sensor placement prevents comprehensive coverage of all indoor areas, potentially leading to blind spots in the data. Portable detection devices offer some flexibility, but still require manual operation, and accurately determining the location of detection points and planning the detection path during measurement is challenging, resulting in inaccurate and incomplete results. Utility Model Content
[0005] To address the issue that traditional photometers require manual handheld operation when measuring indoor photometry, and that the subjective judgment used to determine the location of the measurement point leads to inaccurate results.
[0006] This application provides an indoor light intensity detection device, which adopts the following technical solution:
[0007] An indoor illumination detection device includes a photometer, a mounting base, a base, and a height adjustment mechanism arranged sequentially from top to bottom. The mounting base has a mounting slot on its top that matches the photometer, allowing the photometer to be detachably installed in the slot. A main control module is installed in the mounting base. At least one ranging module for detecting the static distance between the photometer and the walls of the building under test is installed on the side wall of the mounting base. The main control module and each ranging module are fixed to the side wall of the mounting base from different horizontal directions, centered on the mounting base. A motion attitude sensor for monitoring the attitude data of the photometer is installed in the mounting base. The base has a yaw adjustment mechanism for adjusting the yaw attitude of the mounting base. The output end of the yaw adjustment mechanism is fixed to the center of the bottom of the mounting base, and the height adjustment mechanism is fixed to the bottom end of the base. The height adjustment mechanism is used to drive the base to rise and fall vertically to adjust the distance between the photometer and the detection point. A moving part is installed at the bottom of the height adjustment mechanism, and a drive mechanism is installed on the height adjustment mechanism. The output end of the drive mechanism is fixedly connected to the moving part. A data acquisition device for acquiring basic data of the building under test is also installed on the height adjustment mechanism. The motion attitude sensor, data acquisition device, photometer, yaw adjustment mechanism, ranging module and drive mechanism are all electrically connected to the main control module. The main control module is used to receive data from each component and control the working status of each component.
[0008] By adopting the above technical solution, the photometric detector can be detachably installed in the mounting slot on the top of the mounting base, facilitating replacement and maintenance. The ranging module mounted on the side wall of the mounting base can detect the static distance between it and the walls of the building under test. The main control module and each ranging module are fixed to the side wall of the mounting base from different horizontal directions, enabling more comprehensive detection. Combined with the photometric detector's attitude data monitored by the motion attitude sensor, it helps to accurately determine the detection position and path. The yaw adjustment mechanism can adjust the yaw attitude of the mounting base, expanding the detection range. The height adjustment mechanism drives the base to rise and fall vertically, adjusting the distance between the photometric detector and the detection point to adapt to different height detection needs. The moving parts and drive mechanism allow the device to move autonomously to each detection point without manual operation, improving detection efficiency. The data acquisition device can obtain basic data of the building under test, providing more information for detection. All components are electrically connected to the main control module, facilitating automated control and data transmission, avoiding the low efficiency and detection limitations of manual hand-held detection in traditional indoor photometric detection methods. This system addresses issues such as significant human influence, enabling more accurate and comprehensive detection of indoor lighting conditions. In practical applications, after the data acquisition device collects basic data of the building under test, the main control module calculates and determines the detection points and paths based on this data. Then, it controls the drive mechanism to move the moving parts along the detection path to the detection points for testing. Before detection, the motion attitude sensor transmits the current mounting base's attitude data to the main control module. The main control module determines whether the yaw angle of the mounting base and the ranging modules fixed on it has changed based on the mounting base's attitude data. If a yaw angle change occurs, the main control module controls the yaw adjustment mechanism in the base to adjust the mounting base's yaw angle. This allows each ranging module to more accurately measure its static distance from each wall, enabling the main control module to determine whether the photometric detector is at the target detection position based on the static distance detected by each ranging sensor. This achieves fully automatic detection while ensuring accuracy.
[0009] Preferably, the base has a snap-fit block at its bottom end, and the height adjustment mechanism includes an adjustment rod, a mounting plate, a tripod, and a connecting seat. A fixing block is installed at one end of the adjustment plate, and a snap-fit groove matching the snap-fit block is opened on the fixing block. An adjustment component is installed inside the mounting plate, and the adjustment rod passes through the mounting plate and cooperates with the adjustment component. The adjustment component can drive the adjustment rod to move along its axial direction to achieve height adjustment. The top ends of each leg of the tripod are evenly distributed and hinged to the mounting plate along the circumference of the mounting plate, and the other end of each leg is detachably installed on the connecting seat.
[0010] By adopting the above technical solution, the locking block at the bottom of the base engages with the locking groove of the fixing block on the adjustment plate, achieving a stable connection between the base and the height adjustment mechanism. The adjustment component installed inside the mounting plate can drive the adjustment rod to move axially, easily adjusting the height of the photometric detector to adapt to the height requirements of different detection points and improve detection accuracy. The tops of each leg of the tripod are hinged at equal intervals along the circumference of the mounting plate, and the other end of each leg can be detachably mounted on the connecting seat. This ensures the overall stability of the device and facilitates installation and disassembly in different indoor environments, improving the flexibility and adaptability of the device.
[0011] Preferably, the connecting base includes a base and support arms fixed to the side wall of the base corresponding to each leg of the tripod. Each leg is detachably mounted on the corresponding support arm. The drive mechanism includes a drive control unit and a forward drive motor and a steering drive motor electrically connected to the drive control unit. The drive control unit is mounted in the base and electrically connected to the main control module. The moving component includes a wheel cover and a travel wheel mounted in the wheel cover. The steering drive motor is mounted on the support arm, and a transmission shaft is fixedly mounted on the output end of the steering drive motor. The transmission shaft is fixedly connected to the wheel cover. The forward drive motor is mounted in the wheel cover, and the output shaft of the forward drive motor is fixedly connected to the travel wheel.
[0012] By adopting the above technical solution, the base and support arm structure of the connecting seat facilitates the installation of each leg of the tripod, and the legs are detachable, making it convenient for the assembly and disassembly of the device, as well as for carrying and transportation. The drive control unit is electrically connected to the main control module. Under the control of the main control module, the drive control unit can uniformly control the forward drive motor and the steering drive motor. The forward drive motor can drive the travel wheels to rotate, enabling the device to move forward or backward. The steering drive motor drives the wheel cover to rotate through the transmission shaft, realizing the steering of the device. This allows the device to be flexibly moved to different indoor locations for light detection, avoiding the problems of low efficiency of manual handheld detection and the susceptibility of detection data to human factors in traditional detection methods. It also solves the problem that sensors installed in fixed positions cannot fully cover the indoor area, improving the accuracy and comprehensiveness of the detection.
[0013] Preferably, the connecting seat further includes a support rod disposed between the base and each support arm. The support rod includes a fixed rod and a telescopic rod. The telescopic rod is slidably sleeved on the outer periphery of the fixed rod along the axial direction of the fixed rod. A telescopic motor is fixedly installed on the side of the fixed rod near the base. A telescopic shaft is fixedly installed on the output shaft of the telescopic motor. A telescopic cylinder is installed on the inner wall of the fixed rod near the base. The telescopic cylinder is slidably installed in the fixed rod and threadedly connected to the telescopic shaft. A guide groove penetrating the side wall of the fixed rod is opened along the axial direction of the fixed rod. A guide block corresponding to the guide groove is provided on the inner wall of the fixed rod and slides with the guide groove. The guide block passes through the guide groove and is fixed to the telescopic cylinder.
[0014] By adopting the above technical solution, the telescopic motor drives the telescopic shaft to rotate, which in turn drives the telescopic cylinder, which is threadedly connected to it, to slide within the fixed rod. The guide block slides along the guide groove to ensure the linear movement of the telescopic cylinder, thereby causing the telescopic rod to slide axially along the fixed rod, achieving adjustment of the support rod length. This allows the connecting seat to flexibly adjust the distance and position between the support arm and the base according to actual testing needs, enhancing the adaptability and stability of the indoor illumination detection device. It can better adapt to different indoor environments and the layout of testing points, thus improving the accuracy and comprehensiveness of illumination detection.
[0015] Preferably, the adjustment assembly includes an adjustment gear and a lifting motor installed in the adjustment plate. A motor mount is installed on the side wall of the mounting plate, the lifting motor is installed in the motor mount, and the output shaft of the lifting motor is fixed to the adjustment gear. An adjustment rack is provided on the adjustment rod along the axial direction of the adjustment rod, and the adjustment gear meshes with the adjustment rack. The lifting motor is fixedly installed in the mounting plate, and the adjustment gear is rotatably installed in the mounting plate. The lifting motor is electrically connected to the drive control unit. A support base is fixedly installed at the bottom end of the mounting plate. A limit strip is fixedly installed on the outer wall of the adjustment rod along the axial direction of the adjustment rod. A slot adapted to the limit strip is provided at the mounting plate and the support base where the support rod is installed. The mounting plate also includes a bearing platform, and a data acquisition device is installed on the bearing platform. The data acquisition device is located on the opposite side of the lifting motor. A protective cover is also provided on the outer periphery of the data acquisition device, and the protective cover is installed on the bearing platform.
[0016] By adopting the above technical solution, the lifting motor drives the adjusting gear to rotate. The meshing of the adjusting gear with the adjusting rack on the adjusting rod drives the adjusting rod to move axially, enabling convenient adjustment of the height of the height adjustment mechanism. This allows for flexible adjustment of the distance between the photometer and the detection point to meet the illumination detection needs of detection points at different heights. Simultaneously, the support base fixedly installed at the bottom of the mounting plate provides stable support for the bottom of the adjusting rod. Combined with the limiting strip on the outer wall of the adjusting rod and the slots at the mounting plate and support base, this effectively restricts the circumferential rotation of the adjusting rod during movement, ensuring that the adjusting rod always rises and falls smoothly along the axial direction, avoiding any impact on detection accuracy due to shaking. The data acquisition equipment is installed on the support platform of the mounting plate. This installation facilitates the collection of basic data from the building under test. The data acquisition equipment is located opposite the lifting motor to prevent tilting of the entire device's center due to its installation. Furthermore, it effectively avoids the impact of vibration and electromagnetic interference generated by the lifting motor on the data acquisition equipment, ensuring the accuracy and stability of the data acquisition. The protective cover around the data acquisition equipment provides good protection against damage from external factors such as collisions and dust during movement or use, extending the equipment's service life and further ensuring the reliability of the data acquisition function during long-term use.
[0017] Preferably, each of the outriggers is provided with a first pitch adjustment mechanism. Each outrigger includes an inner rod and an outer rod, with the outer rod slidably sleeved on the outer periphery of the inner rod. The first pitch adjustment mechanism includes an adjustment cylinder, a pitch adjustment motor, and an adjustment shaft fixedly installed at the output end of the pitch adjustment motor. The pitch adjustment motor is installed at the end of the inner rod away from the mounting plate. The adjustment cylinder is slidably installed in the inner rod and threadedly connected to the adjustment shaft. The inner rod has a guide rail along its axial direction. A guide block that slides with the guide rail is fixedly installed on the inner wall of the end of the outer rod away from the mounting plate. The guide block passes through the guide rail and is fixed to the adjustment cylinder.
[0018] By adopting the above technical solution, when the pitch angle of the outrigger needs to be adjusted, the pitch adjustment motor is activated to drive the adjustment shaft to rotate. Since the adjustment cylinder is threadedly connected to the adjustment shaft and slidably installed in the inner rod, the rotation of the adjustment shaft causes the adjustment cylinder to move axially within the inner rod. Furthermore, because the guide block passes through the guide rail and is fixed to the adjustment cylinder, and the outer rod is slidably sleeved on the outer circumference of the inner rod, the movement of the adjustment cylinder causes the outer rod to slide relative to the inner rod, thereby achieving a change in the length of the outrigger. Controlling the change in the length of a single outrigger enables adjustment of the pitch angle. This adjustable outrigger structure allows for flexible adjustment of the device's posture and stability according to different indoor ground conditions and testing requirements, ensuring that the photometric meter is in a suitable testing position in various environments. This improves the accuracy and adaptability of indoor illumination testing and avoids deviations in test data caused by uneven ground or other factors.
[0019] Preferably, the upper part of the base has a receiving groove, and the yaw adjustment mechanism is installed in the mounting groove. The yaw adjustment mechanism includes a rotation control unit and an angle servo mechanism. The rotation control unit is electrically connected to the angle servo mechanism, and the output shaft of the angle servo mechanism is coaxial with the base. A limiting platform is provided on the side wall of the upper part of the receiving groove. A wireless charging transmitting coil is installed on the limiting platform. The wireless charging transmitting coil is electrically connected to the rotation control unit. A charging interface is also provided on the base. The charging interface is electrically connected to the rotation control unit. A connecting piece that mates with the output shaft of the angle servo mechanism is fixed at the center of the bottom of the mounting base. A fixing groove is provided on the bottom of the mounting base around the connecting piece. A wireless charging receiving coil that matches the wireless charging transmitting coil is installed in the fixing groove. The wireless charging receiving coil is electrically connected to the main control module.
[0020] By adopting the above technical solution, during the actual operation of the indoor light detection device, the rotation control unit of the yaw adjustment mechanism controls the angle servo mechanism. Since the output shaft of the angle servo mechanism is coaxial with the base and engages with the connecting piece at the center of the bottom of the mounting base, the yaw attitude of the mounting base can be precisely adjusted. This makes the static distances detected by each ranging module between itself and each wall more accurate, thus determining whether the photometric meter is at the target detection position and improving detection accuracy. Simultaneously, the wireless charging transmitting coil on the upper limiting platform of the receiving slot matches the wireless charging receiving coil in the fixed slot at the bottom of the mounting base, enabling wireless charging during device operation. This avoids the inconvenience of frequently plugging and unplugging charging cables, improving the ease of use of the device. Furthermore, the charging interface on the base can serve as a backup charging method. Even if wireless charging fails, the device can still be charged through the charging interface, ensuring continuous and stable operation and providing reliable support for indoor light detection work.
[0021] Preferably, the side wall of the mounting base has a snap-fit slot that matches the main control module and each ranging module. A magnetic female terminal is installed at the bottom of each snap-fit slot, and each magnetic female terminal is electrically connected to the main control module. A magnetic male terminal that matches the magnetic female terminal is installed at the bottom of each ranging module, and each magnetic male terminal is electrically connected to the corresponding ranging module, so that each ranging module can be mechanically fixed and electrically connected to the magnetic female terminal on the side wall of the mounting base through the corresponding magnetic male terminal.
[0022] By adopting the above technical solution, the side wall of the mounting base has slots that match each ranging module, and a magnetic female terminal is installed at the bottom of the slot. The magnetic female terminal is electrically connected to the main control module. Each ranging module has a magnetic male terminal installed at its bottom, and each magnetic male terminal is electrically connected to its corresponding ranging module. This allows the ranging modules to quickly achieve mechanical fixation and electrical connection through the magnetic male terminal and the magnetic female terminal on the side wall of the mounting base. During installation, simply align the magnetic male terminal of the ranging module with the magnetic female terminal at the bottom of the slot and insert it. A stable connection is achieved under magnetic force, and an electrical signal transmission channel is automatically established. No additional bolt fixing or wiring soldering is required, greatly simplifying the installation and removal process of the ranging modules. This allows users to flexibly increase or decrease the number of ranging modules or adjust their installation position according to actual detection needs, improving the assembly efficiency and usage flexibility of the device. When it is necessary to replace or maintain a ranging module, the magnetic connection can be easily separated by gently pulling it out. This convenient and labor-saving operation avoids the damage that may be caused to the device during disassembly using traditional mechanical connection methods, thus extending the service life of the device.
[0023] Preferably, a touch switch is installed on the inner wall of each wheel cover, and the touch switch is electrically connected to the drive control unit.
[0024] By adopting the above technical solution, a touch switch is installed on the inner wall of the wheel cover and electrically connected to the drive control unit. In actual operation, the operator can easily control the drive control unit by touching the touch switch, thereby controlling the forward movement and turning of the moving parts, realizing the flexible movement and positioning of the indoor light detection device. This avoids the traditional complex control method, improves the ease of operation and efficiency of the detection device, and enables more efficient completion of indoor light detection work.
[0025] Preferably, a second pitch adjustment mechanism is provided between each of the support arms and the corresponding moving component mounted on the support arm. The second pitch adjustment mechanism includes an adjustment arm and an adjustment wedge. The adjustment arm is hinged to the end of the support arm away from the moving component. The adjustment wedge is mounted on the wheel cover with its wedge surface facing the support arm. The wedge surface of the adjustment wedge has a limiting groove that matches the shape of the wedge surface. The adjustment arm includes an inner cylinder and an outer cylinder. The outer cylinder is slidably sleeved on the outer circumference of the inner cylinder along the axial direction of the inner cylinder. A connecting rod for connecting the two adjustment arms is provided between the outer cylinders of the two corresponding adjustment arms of each support arm. A wedge rod is hinged at the midpoint of the connecting rod. The free end of the wedge rod abuts in the limiting groove. The drive shaft passes through the adjustment wedge and is fixedly connected to the output end of the steering drive motor. The outrigger is detachably mounted on the outer cylinder of the adjustment arm.
[0026] By adopting the above technical solution, the second pitch adjustment mechanism enables the moving component to adjust its pitch angle on the support arm, adapting to different indoor ground conditions and allowing the device to maintain stable movement and detection posture even in complex ground environments. The inner and outer cylinder structures of the adjustment arm, as well as the cooperation of the connecting rod, wedge rod, and adjusting wedge block, can flexibly change the pitch angle of the moving component, preventing the device from tipping over or inaccurate detection data due to uneven ground. Simultaneously, the outriggers are detachably mounted on the outer cylinder of the adjustment arm, facilitating assembly and adjustment of the device according to actual detection needs, improving the device's adaptability and flexibility. This allows for more comprehensive and accurate indoor illumination detection. Furthermore, the second pitch adjustment mechanism is driven by the rotation of a steering drive motor; that is, the rotation of the steering drive motor not only drives the travel wheels to change the direction of movement but also adjusts the pitch angle of the photometric meter.
[0027] In summary, this application includes at least one of the following beneficial technical effects:
[0028] 1. By utilizing moving parts, a drive mechanism, and a height adjustment mechanism, the device can automatically move and adjust its height, avoiding manual hand operation, improving detection efficiency, and reducing manpower and time consumption;
[0029] 2. By detecting the static distance to the wall through the ranging module and monitoring the attitude data through the motion attitude sensor, combined with the basic data obtained by the data acquisition equipment, the location of the detection point can be accurately determined and the detection path can be reasonably planned, avoiding blind spots in the detection data and improving the accuracy and comprehensiveness of the detection results;
[0030] 3. The yaw adjustment mechanism can adjust the yaw attitude of the mounting base, thereby adjusting the detection direction of the photometer, enabling a more comprehensive detection of the lighting conditions in different directions indoors. Attached Figure Description

[0045] Example 1:
[0046] This application discloses an indoor light detection device.
[0047] Reference Figure 1 and Figure 2The indoor light detection device provided in this application includes a photometer 1, a mounting base 2, a base 3, and a height adjustment mechanism 4 arranged sequentially from top to bottom. The top of the mounting base 2 has a mounting groove 21 that matches the photometer 1. The photometer 1 can be detachably installed in the mounting groove 21 for easy replacement and maintenance. A main control module 5 is installed in the mounting base 2, and at least one ranging module 6 is installed on the side wall of the mounting base 2. Each ranging module 6 is electrically connected to the main control module 5. The main control module 5 and each ranging module 6, centered on the mounting base 2, measure light from different horizontal directions. Fixed to the side wall of mounting base 2, forming a layout where the components are horizontally dispersed yet tightly integrated with mounting base 2, collectively forming part of the overall structure. This allows for the detection of static distances between the device and the wall. The output ports of each ranging module 6 are electrically connected to the input / output ports of the main control module 5, transmitting the detected static distances between the device and the walls of the building in real time to the main control module 5. Motion attitude sensors are also installed in mounting base 2. The system monitors the attitude data of the photometer 1. The motion attitude sensor is electrically connected to the main control module 5 to transmit the collected attitude data of the photometer 1 to the main control module 5. The main control module 5 can determine whether the photometer 1 has experienced a change in yaw or pitch angle based on the attitude data monitored by the motion attitude sensor. The base 3 is equipped with a yaw adjustment mechanism 10, which can adjust the yaw attitude of the mounting base 2. The input port of the yaw adjustment mechanism 10 is electrically connected to the output port of the main control module 5. The main control module 5 determines whether the photometer 1 is currently yawing based on the motion attitude sensor. When the angle changes, the yaw adjustment mechanism 10 controls the yaw angle of the photometer 1 to adjust to the target yaw state; the height adjustment mechanism 4 is fixed to the bottom of the base 3 and can drive the base 3 to rise and fall in the vertical direction, thereby adjusting the distance between the photometer 1 and the detection point. The bottom of the height adjustment mechanism 4 is equipped with a moving part 8, and a drive mechanism is installed on the height adjustment mechanism 4. The input port of the drive mechanism is electrically connected to the output port of the main control module 5, and the output end of the drive mechanism is fixed to the moving part 8, so that the main control module 5 of the drive module can drive the moving part 8 to move.The height adjustment mechanism 4 is also equipped with a data acquisition device 7 for collecting basic data of the building under test. The output port of the data acquisition device 7 is electrically connected to the input port of the main control module 5, so that the data acquisition device 7 can transmit the collected basic data of the building under test to the main control module 5 in real time. The main control module 5 can calculate and determine the corresponding detection points and detection paths based on the basic data of the building under test, and then control the drive component to drive the moving component 8 to move according to the detection path. In practical applications, after the data acquisition device 7 collects the basic data of the building under test, the main control module 5 calculates and determines the detection points and detection paths of the building under test based on the basic data, and then controls the drive mechanism to drive the moving component 8 to move according to the detection path. The path moves to the detection point for detection. Before detection, the motion attitude sensor detects and transmits the attitude data of the current mounting base 2 to the main control module 5. The main control module 5 determines whether the yaw angle of the current mounting base 2 and the ranging module 6 fixed on the mounting base 2 has changed based on the attitude data of the mounting base 2. If the yaw angle changes, the main control module 5 controls the yaw adjustment mechanism 10 in the base 3 to adjust the yaw angle of the mounting base 2, so that each ranging module 6 can more accurately measure its static distance to each wall. This allows the main control module 5 to determine whether the photometric detector 1 is at the target detection position of the detection point based on the static distance detected by each ranging sensor, thus achieving fully automatic detection while ensuring detection accuracy.
[0048] Reference Figure 2 The photometer 1 is a key component for detecting indoor light intensity. It boasts high-precision detection capabilities, accurately measuring light intensity under various environmental conditions. The photometer 1 typically employs advanced photoelectric conversion technology to convert light signals into electrical signals for processing. Its appearance is generally a regular shape, such as a sphere, facilitating installation in the mounting slot 21 of the mounting base 2. The photometer 1 can utilize commercially available high-precision light sensors, or it can be customized with special functions to meet specific needs. The top of the mounting base 2 has a mounting slot 21 that matches the photometer 1. The size and shape of the mounting slot 21 are designed according to the shape of the photometer 1 to ensure its stable installation. An elastic pad can be installed at the bottom of the mounting slot 21 to cushion and fix the photometer 1, preventing it from shaking during movement.
[0049] Reference Figure 1The main control module 5 and at least one ranging module 6 are mounted on the side wall of the mounting base 2. The main control module 5 is the core of the entire device, employing a high-performance microprocessor with powerful computing and control capabilities. The main control module 5 is electrically connected to various components via wires or onboard circuitry, enabling data transmission and control command delivery. The ranging module 6 detects the static distance between the mounting base 2 and the walls of the building under test. It uses ultrasonic or laser ranging technology, featuring high measurement accuracy and fast response. The transmitting and receiving windows of the ranging module 6 face the wall. The main control module 5 and each ranging module 6 are fixed to the side wall of the mounting base 2 from different horizontal directions, centered on the mounting base 2, ensuring accurate measurement of the distance to the wall in various directions.
[0050] Reference Figure 2 and Figure 3 The installation method of the ranging module 6 and the mounting base 2 is as follows: the side wall of the mounting base 2 is provided with a slot 25 that matches the ranging module 6. A magnetic female end 26 is installed at the bottom of each slot 25. Each magnetic female end 26 is electrically connected to the main control module 5. A magnetic male end 61 that matches the magnetic female end 26 is installed at the bottom of each ranging module 6. Each magnetic male end 61 is electrically connected to the corresponding ranging module 6, so that each ranging module 6 can be mechanically fixed and electrically connected through the magnetic male end 61 and the magnetic female end 26 at the bottom of the slot 25. During installation, simply align the magnetic male end 61 of the ranging module 6 with the magnetic female end 26 at the bottom of the slot 25 and insert it. A stable connection can be completed under the action of magnetic force. At the same time, an electrical signal transmission channel is automatically established. No additional bolt fixing or wire soldering operation is required, which greatly simplifies the installation and removal process of the ranging module 6. It is convenient for users to flexibly increase or decrease the number of ranging modules 6 or adjust their installation position according to actual detection needs, thereby improving the assembly efficiency and usage flexibility of the device. When it is necessary to replace or maintain a distance measuring module 6, the magnetic connection can be easily separated by gently pulling it out. This operation is convenient and effortless, avoiding the damage that may be caused to the device during disassembly using traditional mechanical connections, and thus helping to extend the service life of the device. At the same time, the locking slot 25 provides good positioning for the distance measuring module 6, ensuring that the distance measuring module 6 maintains the preset detection angle after installation, further improving the accuracy of distance detection.
[0051] Reference Figure 2The motion attitude sensor is used to monitor the attitude data of the photometer 1, such as yaw angle and pitch angle. The motion attitude sensor can be a high-precision gyroscope or accelerometer, which can accurately acquire the motion state of the photometer 1 in real time. The motion attitude sensor is installed inside the mounting base 2 and can be connected to the main control module 5 via a data cable, or it can be directly installed on the main control module 5 to realize the data transmission and control command transmission between the motion attitude sensor and the main control module 5. That is, the motion attitude sensor can transmit the detected attitude data to the main control module 5 for analysis and processing in real time.
[0052] Reference Figure 2 The base 3 has a receiving groove 31 on its upper part, and the yaw adjustment mechanism 10 is installed in the receiving groove 31. The yaw adjustment mechanism 10 includes a rotation control unit 101 and an angle servo mechanism 102. The input port of the rotation control unit 101 is electrically connected to the output port of the main control module 5, and the output port of the rotation control unit 101 is electrically connected to the input port of the angle servo mechanism 102. The rotation control unit 101 adopts an advanced control algorithm, which can accurately control the rotation angle of the angle servo mechanism 102. The angle servo mechanism 102 has a high-precision positioning capability. The output axis of the angle servo mechanism 102 is collinear with the center line of the base 3. A connector 22 matching the output axis of the angle servo mechanism 102 is fixed at the center of the bottom of the mounting base 2. By fixing the angle servo mechanism 102 to the connector 22 at the bottom of the mounting base 2, the axis of the mounting base 2 and the base 3 can be aligned. The lines are aligned to ensure the rotational accuracy of the mounting base 2, thereby adjusting its yaw attitude. A limiting platform 32 is provided on the upper side wall of the receiving groove 31, on which a wireless charging transmitting coil 33 is installed. The wireless charging transmitting coil 33 is electrically connected to the rotation control unit 101. A charging interface 103 is also provided on the base 3, which is electrically connected to the rotation control unit 101. A fixing groove 23 is provided at the bottom of the mounting base 2 on the outer periphery of the connector 22. A wireless charging receiving coil 24 matching the wireless charging transmitting coil 33 is installed in the fixing groove 23, and the wireless charging receiving coil 24 is electrically connected to the main control module 5. When the mounting base 2 and the base 3 are engaged, the wireless charging transmitting coil 33 and the wireless charging receiving coil 24 sense each other, realizing wireless charging of the device inside the mounting base 2. At the same time, the charging interface 103 can also perform wired charging when necessary, ensuring a stable power supply for the device.
[0053] Reference Figure 2A first power supply 104 can be installed in the base 3. The first power supply 104 can store electrical energy input through the charging interface 103. A second power supply 51 can be installed in the main control module 5. During the operation of the device, the electrical energy of the first power supply 104 can be emitted by the wireless charging transmitting coil 33 through the rotation control unit 101. The main control unit controls the wireless charging receiving coil 24 to provide electrical energy to the main control module 5. The energy can also be stored in the second power supply 51 for convenient use.
[0054] Reference Figure 1 , Figure 8 and Figure 9The height adjustment mechanism 4 is fixed to the bottom of the base 3. The height adjustment mechanism 4 includes an adjustment rod 41, a mounting plate 42, a tripod, and a connecting seat 44. A fixing block 45 is installed at one end of the adjustment rod 41. A snap-fit groove 451 is opened at the top of the fixing block 45. A snap-fit block 34 is provided at the bottom of the base 3. The snap-fit groove 451 and the snap-fit block 34 cooperate with each other to fix the fixing block 45 and the base 3, thereby realizing the installation of the mounting seat 2, the photometer 1, the main control module 5, and the distance measuring module 6 with the height adjustment mechanism 4. The other end of the adjustment rod 41 passes through the mounting plate 42 and cooperates with the adjustment component. An adjustment rack 411 is opened along the axial direction of the adjustment rod 41. The adjustment component includes an adjustment gear 421 rotating in the mounting plate 42 and a lifting motor 422. The lifting motor 422 is mounted on the side wall of the mounting base 2. To ensure the stability of the lifting motor 422, a motor mount 4221 is provided at the mounting location of the lifting motor 422. The lifting motor 422 is installed in the motor mount 4221, which is fixedly connected to the side wall of the mounting base 2 by bolts. This facilitates the installation and removal of the motor and effectively enhances the connection strength between the motor mount 4221 and the mounting base 2, preventing the lifting motor 422 from shifting position due to vibration during operation. The legs 43 of the triangular bracket are hinged to the side wall of the mounting plate 42. Therefore, the installation position of the lifting motor 422 is located between the two legs 43. The output shaft of the lifting motor 422 is fixedly installed with the adjusting gear 421 so that the lifting motor 422 can drive the adjusting gear 421 during operation. When the spur gear 421 rotates, the adjusting gear 421 meshes with the adjusting rack 411 on the adjusting rod 41, so that the rotation of the adjusting gear 421 can drive the adjusting rod 41 to move axially. A support base 423 is fixedly installed at the bottom of the mounting plate 42. The adjusting rod 41 passes through the support base 423 and slides with the support base 423. A limit strip 412 is fixedly installed on the adjusting rod 41 axially. The support base 423 and the mounting plate 42 are provided with a groove 424 that matches the limit strip 412 at the mounting point of the adjusting rod 41. Through the cooperation of the limit strip 412 of the adjusting rod 41 with the groove 424 of the mounting plate 42 and the support base 423, the circumferential rotation of the adjusting rod 41 during the movement can be effectively restricted, ensuring that the adjusting rod 41 always moves smoothly up and down axially and avoiding the effects of shaking. To improve detection accuracy, it is conceivable that, in order to avoid the limiting strip 412 affecting the meshing of the adjusting gear 421 and the adjusting rack 411, the limiting strip 412 can be set at a position other than the adjusting rack 411 on the adjusting rod 41, or at a position symmetrical to the adjusting rack 411 with the axis of the adjusting rod 41 as the axis of symmetry. The top ends of each leg 43 of the tripod are evenly distributed and hinged to the mounting plate 42 along the circumference of the mounting plate 42. The connecting seat 44 includes a base 441 and a support arm 442 fixed to the side wall of the base 441 and corresponding to each leg 43 of the tripod. Each leg 43 can be detachably installed on the corresponding support arm 442, so that the height adjustment mechanism 4 has good stability and adjustability and can adapt to different detection needs.
[0055] Reference Figure 1 and Figure 10 The mounting plate 42 also includes a support platform 425, on which the data acquisition device 7 is mounted. To prevent environmental pollution from affecting the data acquisition accuracy of the data acquisition device 7, a protective cover 71 is provided on the outer periphery of the support platform 425 around the data acquisition device 7. The protective cover 71 is made of materials such as optical glass and polycarbonate (PC). The protective cover 71 is detachably mounted on the support platform. The detachable mounting method can be achieved by snapping the protective cover 71 to the mounting point of the support platform 425. It is conceivable that, in order to avoid the performance of the data acquisition device 7 being affected by excessive temperature during operation, multiple ventilation holes penetrating the support platform 425 are provided within the coverage area of the protective cover 71. The inside of the ventilation holes is covered with a dust filter, which can not only ensure air circulation inside the cover and prevent the normal operation of the data acquisition device 7 from being affected by excessive temperature, but also further block fine particles from entering. It is easy to imagine that the installation of the data acquisition device 7 on the support platform 425 may change the center of gravity of the entire device. Therefore, the installation position of the data acquisition device 7 is located on the opposite side of the installation position of the lifting motor 422. Through the installation of the lifting motor 422 and the data acquisition device 7, a balanced configuration of weight on both sides is formed, which effectively reduces the risk of the device tilting or shaking due to the shift of the center of gravity.
[0056] The cable from the input port of the lifting motor 422 is connected to the output port of the drive control unit 111 via the inside of the tripod leg 43, thus establishing an electrical connection between the drive control unit 111 and the lifting motor 422. This allows the drive control unit 111 to control the operating state of the lifting motor 422. The electrical connection between the lifting motor 422 and the drive control unit 111 can be achieved through the installation method between the tripod leg 43 and the support rod 443, similar to the installation method between the ranging module 6 and the mounting base 2. A magnetic male terminal is installed at the bottom of the leg 43, which is electrically connected to the lifting motor 422. A magnetic female terminal is installed at the fixing point between the support rod 443 and the leg 43, and is electrically connected to the drive control unit 111. The cable length connecting the lifting motor 422 and the drive control unit 111 is greater than the sum of the maximum extension length of the support rod 443, the maximum adjustment length of the outrigger 43, and the maximum range of rotation achieved by the outrigger 43 hinged to the mounting plate 42. This ensures that the cable of the lifting motor 422 will not be damaged by pulling during equipment use. At the same time, the cable length connecting the pitch adjustment motor 121 installed in the outrigger 43, the steering drive motor 112 installed on the support arm 442, and the forward drive motor 113 installed in the wheel cover 81 to the drive control unit 111 is greater than the maximum extension range of the support rod 443. This ensures that the cable will not be damaged by pulling when the support rod 443 is adjusted.
[0057] The transmission of data and control signals between the drive control unit 111 and the rotation control unit 101 and the main control module 5 can be achieved by setting communication units on the main control module 5, the drive control unit 111 and the rotation control unit 101 respectively, and the transmission of data and control signals can be achieved through the communication units.
[0058] Reference Figure 1 and Figure 8 Each leg 43 of the tripod is equipped with a first pitch adjustment mechanism 12. The first pitch adjustment mechanism 12 includes an adjustment cylinder 123, a lifting motor, and an adjustment shaft 122 fixedly installed on the output shaft of the lifting motor. The adjustment cylinder 123 is slidably installed in the inner rod 432 and threadedly connected to the adjustment shaft 122. The adjustment cylinder 123 is installed on the inner wall of the outer rod 431 on the side away from the mounting plate 42. The lifting motor is installed on the inner rod 432 on the side away from the mounting plate 42. A through-hole is formed in the side wall of the inner rod 432 along the axial direction of the inner rod 432. The guide rail 4321 has a guide block 4311 on the inner wall of the outer rod 431 at a position corresponding to the guide rail 4321. The guide block 4311 slides with the guide rail 4321 and passes through the guide rail 4321 and is fixedly connected to the adjusting cylinder 123. The adjusting shaft 122 is rotated by the lifting motor. With the cooperation of the guide rail 4321, the guide block 4311 and the adjusting cylinder 123, the adjusting cylinder 123 slides along the axial direction of the adjusting shaft 122, thereby realizing the lifting and lowering of the support leg 43, and thus realizing the pitch angle adjustment of the photometric detector 1.
[0059] Reference Figure 4 - Figure 6A moving part 8 is mounted at the bottom of the height adjustment mechanism 4, and a drive mechanism is mounted on the height adjustment mechanism 4. The drive mechanism includes a drive control unit 111 and a forward drive motor 113 and a steering drive motor 112 electrically connected to the drive control unit 111. The drive control unit 111 is mounted in the base 441, and the output port of the main control module 5 is electrically connected to the input port of the drive control unit 111 to control the drive mechanism. The output port of the drive control unit 111 is connected to the input port of the steering drive motor 112 and the input port of the forward drive motor 113. The input port of component 3 is electrically connected to control the steering drive motor 112 and the forward drive motor 113. The moving component 8 includes a wheel cover 81 and a traveling wheel 82 installed in the wheel cover 81. A transmission groove 4421 is provided on the support arm 442. The steering drive motor 112 is installed on the support arm 442. A transmission shaft 115 is fixedly installed on the output end of the steering drive motor 112 and is fixedly connected to the wheel cover 81. The forward drive motor 113 is installed in the wheel cover 81 and its output shaft is fixedly connected to the traveling wheel 82. Through the coordinated work of the forward drive motor 113 and the steering drive motor 112, the forward, backward, and steering functions of the device are realized. The height adjustment mechanism 4 is also equipped with a data acquisition device 7 for acquiring basic data of the building under test. The data acquisition device 7 can use a camera, lidar, etc., and can acquire information such as the layout and structure of the building to provide decision-making basis for the main control module 5.
[0060] Reference Figures 4-6 To protect the steering drive motor 112, its installation position can be the lower end of the support arm 442 parallel to the moving part 8. The support arm 442 has a transmission groove 4421 at its top end where the moving part 8 and steering drive motor 112 are located. The moving part 8 is located below the transmission groove 4421 near the free end of the support arm 442. The steering drive motor 112 is located at the other end of the transmission groove 4421. The output shaft of the steering drive motor 112 is fixedly mounted with a drive shaft 114, which is rotatably mounted in the transmission groove 4421. The drive shaft is fixed on the wheel cover 81 of the moving part 8. The drive shaft 115 is rotatably installed in the transmission groove 4421, and the drive shaft 115 is parallel to the drive shaft 114. A transmission toothed belt 117 is installed between the drive shaft 115 and the drive shaft 114. In order to ensure the transmission of power, both the drive shaft 114 and the drive shaft 115 are provided with teeth. The transmission of power is achieved by meshing with the transmission toothed belt 117. In order to ensure the transmission of power by the transmission toothed belt 117, a tensioning wheel is installed on the side wall of the transmission groove 4421. The tensioning wheel meshes with the transmission toothed belt 117 and applies pressure to it so that the transmission toothed belt 117 always keeps in close contact with the drive shaft 114 and the drive shaft 115.
[0061] Reference Figure 6A touch switch 83 is installed on the inner wall of the wheel cover 81. Each wheel cover 81 has a touch switch 83 installed on its side wall. The touch switch 83 is electrically connected to the drive control unit 111. When the photometer 1 is moving and performing photometer detection, if the wheel cover 81 is touched by the operator's manual contact or by an external force that collides with an obstacle, the touch switch 83 is triggered, which can directly control the forward wheel 82 to stop rotating, thus preventing the equipment from continuing to move under unexpected circumstances.
[0062] Reference Figure 6 and Figure 7 The connecting seat 44 also includes a support rod 443 disposed between the base 441 and each support arm 442. The support rod 443 includes a fixed rod 4432 and a telescopic rod 4431. The telescopic rod 4431 is slidably sleeved on the outer periphery of the fixed rod 4432 along the axial direction of the fixed rod 4432. A telescopic motor 131 is fixedly installed on the side of the fixed rod 4432 near the base 441. The input port of the telescopic motor 131 is electrically connected to the output port of the drive control unit 111. A telescopic shaft 132 is fixedly installed on the output shaft of the telescopic motor 131. A telescopic cylinder 133 is installed on the inner wall of the fixed rod 4432 near the base 441. The telescopic cylinder 133 is slidably installed in the fixed rod 4432 and is connected to the telescopic rod 4432. The shaft 132 is threaded. The side wall of the fixed rod 4432 is provided with a guide groove 44321 that passes through the side wall of the fixed rod 4432 along the axial direction of the fixed rod 4432. The inner wall of the fixed rod 4432 is provided with a guide block 44311 that slides with the guide groove 44321 at the corresponding position. The guide block 44311 passes through the guide groove 44321 and is fixed to the telescopic cylinder 133. Under the control of the drive control unit 111, when the telescopic motor 131 is working, the output shaft rotates, which can drive the telescopic cylinder 133 to slide in the fixed rod 4432, thereby driving the telescopic rod 4431 to move along its axial direction, thereby realizing the length adjustment of the support arm 442 to adapt to more detection environments and detection points.
[0063] The implementation principle of this embodiment is as follows:
[0064] This indoor illumination detection device achieves automatic detection of indoor illumination through the coordinated operation of its components. The main control module 5, based on the basic data acquired by the data acquisition device 7 and the distance data measured by the ranging module 6, controls the drive mechanism to move the moving component 8 to the appropriate detection position. The height of the photometer 1 can be adjusted via the height adjustment mechanism 4, and the yaw adjustment mechanism 10 can adjust the yaw attitude of the mounting base 2, enabling the photometer 1 to accurately move to the detection point. The motion attitude sensor monitors the attitude data of the photometer 1 in real time, ensuring the stability and accuracy of the detection process. The photometer 1 transmits the detected illumination intensity data to the main control module 5 for processing and analysis. Compared to traditional indoor photometer detection equipment, this device reduces manpower and time consumption, avoids the influence of human factors on the detection results, and improves detection efficiency and accuracy.
[0065] Example 2
[0066] Reference Figures 11-13 The difference between this embodiment and Embodiment 1 is that a second pitch adjustment mechanism 14 is further provided between each support arm 442 and the corresponding moving part 8 mounted on the support arm 442. The second pitch adjustment mechanism 14 includes an adjustment arm 141 and an adjustment wedge 142. The adjustment arm 141 is hinged to the end of the support arm 442 away from the moving part 8. The adjustment wedge 142 is mounted on the wheel cover 81 with its wedge surface facing the support arm 442. The wedge surface of the adjustment wedge 142 has a limiting groove 1421 that matches the shape of the wedge surface. The adjustment arm 141 includes an inner cylinder. 1412 and outer cylinder 1411. The outer cylinder 1411 is slidably sleeved on the outer periphery of the inner cylinder 1412 along the axial direction of the inner cylinder 1412. A connecting rod is provided between the outer cylinder 1411 of the two adjusting arms 141 corresponding to each support arm 442 to realize the connection of the two adjusting arms 141. A wedge rod 144 is hinged at the midpoint of the connecting rod. The free end of the wedge rod 144 abuts in the limiting groove 1421. The transmission shaft 115 passes through the adjusting wedge block 142 and is fixedly connected to the output end of the steering drive motor 112. The support leg 43 is detachably installed on the outer cylinder 1411 of the adjusting arm 141.
[0067] The implementation principle of this embodiment is as follows:
[0068] When the pitch angle needs to be adjusted, the drive control unit 111 controls the steering drive motor 112 to rotate, thereby driving the wheel cover 81 and the adjusting wedge 142 fixed on the top of the wheel cover 81 to rotate. The wedge rod 144 abuts against the limiting groove 1421 of the adjusting wedge 142. When the adjusting wedge 142 rotates, the wedge rod 144 remains without displacement. The wedge surface characteristics of the adjusting wedge 142 are used to push the wedge rod 144 to move, thereby driving the outer cylinder 1411 of the two adjusting arms 141 to slide along the axial direction of the inner cylinder 1412, realizing the extension and retraction of the overall length of the adjusting arm 141. When the length of the adjusting arm 141 changes, the position of its hinge point with the support arm 442 changes relative to each other, thereby driving the support arm 442 to pitch and rotate around the moving part 8 to adapt to different ground slopes or detection scenario requirements.
[0069] The above are all preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
