Description

Technical Field

[0001] This invention relates to the field of power equipment foundation pit acceptance measurement technology, and in particular to a method and system for measuring equipment foundation pits based on infrared remote sensing technology. Background Technology

[0002] Before the installation of electrical equipment, the dimensional accuracy of the foundation pit directly affects the safe and stable operation of the equipment. Currently, foundation pit acceptance relies heavily on manual measurement in the pit, which suffers from low efficiency, high safety risks, and difficulty in guaranteeing data accuracy.

[0003] Specifically, the following methods are currently mainly used for foundation pit acceptance: (1) Manual measurement in the pit: Surveyors enter the pit and use tools such as tape measures to measure and record the data manually. However, this method is unsafe, as personnel need to go down into the pit to measure, which poses safety risks such as falls from heights and pit collapse.

[0004] (2) Simple measuring tools are used: such as laser rangefinders, but they cannot simultaneously and accurately measure tilt, diameter, etc. However, this method is inefficient, and manual measurement, recording, and data processing are time-consuming and labor-intensive. Moreover, the accuracy is difficult to guarantee, and manual measurement errors are large when the shape of the foundation pit is irregular. In addition, data management is inconvenient, and the measurement results are mostly paper or scattered electronic records, making it difficult to form a standardized ledger.

[0005] (3) Traditional remote sensing equipment: such as total station, which is expensive and complicated to operate, and is not suitable for rapid on-site acceptance. Summary of the Invention

[0031] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings.

[0032] like Figure 1 As shown, this embodiment of the invention provides a method for measuring equipment foundation pits based on infrared remote sensing technology, including: S1: The measuring device consisting of an infrared laser rangefinder and a gyroscope performs vertical and horizontal measurements at different locations on the equipment foundation pit to be measured, thereby obtaining the depth and diameter data of the equipment foundation pit; S2: Perform data conversion on the depth data and diameter data to obtain multiple depth measurement values ​​and diameter measurement values; S3: Based on the multiple depth measurements and diameter measurements, determine the target depth measurement value characterizing the depth of the equipment pit and the target diameter measurement value characterizing the diameter of the equipment pit.

[0033] In this embodiment, an infrared laser rangefinder and a gyroscope are combined to form a measuring device. This device can be connected to an external controller to transmit measurement data. The controller processes the data, determines the final measurement value, and displays it. The controller can be a fixed unit, such as a server or console, or a handheld terminal device, such as a standalone testing terminal. For details, please refer to [reference needed]. Figure 2As shown, it includes a test host equipped with a communication antenna, a display screen, and a sensor connector for connecting an infrared laser rangefinder sensor. This sensor may contain a tilt sensor, equivalent to a gyroscope. The connector and the test host are connected via a universal adjustable metal tube to facilitate adjustment of the test direction and position. Alternatively, the controller could be a user's mobile phone, etc., and is not limited to any particular type of device. This embodiment significantly improves the safety and efficiency of foundation pit measurement, enabling personnel to measure without entering the pit, significantly reducing operational risks and improving acceptance efficiency. By using infrared remote sensing technology and algorithm models to determine the measured values ​​of the foundation pit, the measurement accuracy is greatly improved compared to manual measurement. Furthermore, the overall measurement process is convenient and quick, and the designed measurement device is lightweight, suitable for rapid deployment and use on-site. In addition, the measurement device and solution of this embodiment have a wide range of applications and can be used to measure equipment foundation pits of different shapes, depths, and locations.

[0034] In one embodiment, a measuring device composed of an infrared laser rangefinder and a gyroscope is used to perform vertical measurements at different locations of the equipment foundation pit under test, including: S101: The first measuring device, composed of the first infrared laser rangefinder and the first gyroscope, performs vertical measurements at different positions of the equipment pit to be measured.

[0035] Specifically, the first measuring device is connected to a mobile device for moving the first measuring device; The first measuring device, composed of a first infrared laser rangefinder and a first gyroscope, performs vertical measurements at different locations on the equipment foundation pit to be measured, including: S102: Control the mobile device to drive the first measuring device composed of the first infrared laser rangefinder and the first gyroscope to perform vertical measurements on the equipment pit at different positions.

[0036] Furthermore, a measuring device composed of an infrared laser rangefinder and a gyroscope is used to perform horizontal measurements at different locations of the equipment pit under test, including: S103: The second measuring device, consisting of a second infrared laser rangefinder and a second gyroscope, performs horizontal measurements of the equipment pit under test from different orientations.

[0037] Specifically, the second measuring device is connected to a rotating device for driving the second measuring device to change its orientation; The second measuring device, composed of a second infrared laser rangefinder and a second gyroscope, performs horizontal measurements of the equipment foundation pit under test from different orientations, including: S104: Control the rotating device to drive the second measuring device composed of the second infrared laser rangefinder and the second gyroscope to perform horizontal measurements of the equipment pit to be measured from different directions.

[0038] Based on the above embodiments, it can be seen that the measuring device of this application includes two branches, namely a first measuring device and a second measuring device, and belongs to a measuring device design with dual probes. Specifically, the measuring device in this embodiment has a vertical ranging probe and a horizontal ranging probe. The vertical ranging probe is connected to a first gyroscope, and the horizontal ranging probe is connected to a second gyroscope. Vertical ranging probe: Function: Specifically used for measuring the depth of foundation pits.

[0039] Technical requirements: Use a high-precision infrared laser rangefinder sensor, with a range covering the expected maximum pit depth of 20 meters and an accuracy of ±1cm.

[0040] Operating mode: With feedback and assistance from the connected first gyroscope, the emitted infrared laser beam is ensured to be absolutely perpendicular to the horizontal plane. The measured value is the depth of the pit at that point.

[0041] In practical applications, it can be connected to a mobile device so that the mobile device can move the measuring device to different locations for measurement.

[0042] Horizontal ranging probe: Function: Specifically used to measure the diameter of a foundation pit in the horizontal direction.

[0043] Technical requirements: The same high-precision infrared laser rangefinder is used. The measuring range can be determined according to actual needs, and the accuracy is ±1cm.

[0044] Operating mode: Maintains absolute horizontal position with feedback and assistance from the connected second gyroscope.

[0045] In actual measurements, the measuring device can be connected to a rotating device to allow the measuring device to adjust its direction on the horizontal plane. For example, during measurement, the measuring direction can be adjusted by rotating the device, and then the diameter of the foundation pit in different orientations can be measured.

[0046] In another embodiment, the measuring device is further configured with an accelerometer (IMU); further, the method also includes: S4: During the measurement, the accelerometer data is read in real time, and the angle between the current orientation of the infrared laser rangefinder and the direction of gravity is determined based on the accelerometer data; S5: Determine the adjustment strategy for the position and attitude of the infrared laser ranging sensor based on the included angle and the current measurement mode of the measuring device.

[0047] Specifically, the strategy for determining the attitude adjustment of the infrared laser rangefinder sensor based on the included angle and the current measurement mode of the measuring device includes: S501: When the measuring device is in vertical measurement mode, determine whether the included angle is zero. If it is non-zero, determine the current attitude of the infrared laser ranging sensor based on the included angle, and determine the first adjustment strategy based on the current attitude. S502: When the measuring device is in horizontal measurement mode, determine whether the included angle is 90°. If it is not 90°, determine the current attitude of the infrared laser ranging sensor based on the included angle, and determine the second adjustment strategy in combination with the current attitude.

[0048] For example, in this embodiment, each probe integrates a high-precision MEMS gyroscope and accelerometer (IMU), such as, but not limited to, an MPU6050. During vertical calibration, the processor in the ground control station or the testing instrument reads the IMU data of the vertical probe (first infrared laser rangefinder sensor) in real time, and then calculates the angle between the probe's current vertical test position and the direction of gravity. If the angle is not zero, it indicates that the vertical test angle needs to be adjusted. Therefore, the probe position can be manually adjusted according to the angle, or the ground control station or the testing instrument can dynamically adjust the position of the probe or the moving device according to the angle. If the probe position needs to be adjusted, an angle-adjustable device needs to be added to mount the probe, such as a pan-tilt unit, a motorized universal connector, etc., to keep the probe in a vertical state and accurately complete the vertical measurement.

[0049] During horizontal calibration, similar to vertical calibration, the ground control station or testing instrument reads the IMU data of the horizontal probe in real time to determine the angle between the horizontal probe and the direction of gravity, or the angle between the horizontal probe and the horizontal plane. In this embodiment, the angle with the direction of gravity is determined. If the angle is not 90°, it means that the current position of the horizontal probe needs to be adjusted. Therefore, the probe can be adjusted using the method listed in the previous embodiment to ensure that the probe remains horizontal and accurately completes the diameter measurement in the horizontal direction.

[0050] The calibration process described above completely eliminates measurement posture problems caused by improper equipment placement, fundamentally ensuring the accuracy of the measurement reference, that is, ensuring the measurement accuracy of the equipment pit, and minimizing measurement errors.

[0051] Furthermore, when using IMU data for attitude calculation, the specific data can be determined based on the number of data bytes, and the acquired signal value can be obtained by register splicing, etc., to achieve non-contact measurement of parameters such as pit depth and pit wall inclination. The measurement data is processed by the built-in data processing algorithm of the main control (processor in the test instrument or ground control station) to obtain the measurement value.

[0052] After the measurement is completed, the depth and diameter data need to be converted, including: S201: The depth data and diameter data are uniformly converted from the current data format to the target data format, including the decimal data format.

[0053] In this embodiment, the received data is two bytes of ASCII code or hexadecimal data. After distinguishing between endianness, the algorithm converts the data into a decimal value using a data conversion algorithm. Of course, the received data can also be in other formats, but all of them must be converted into decimal values.

[0054] In one embodiment, such as Figure 3 As shown, determining the target depth measurement value characterizing the depth of the equipment foundation pit and the target diameter measurement value characterizing the diameter of the equipment foundation pit based on multiple depth measurement values ​​and diameter measurement values ​​includes: S401: Determine the minimum depth measurement value based on the multiple depth measurement values, and define the minimum depth measurement value as the target depth measurement value characterizing the depth of the equipment pit; S402: Determine the maximum diameter measurement value based on the multiple diameter measurements, and define the maximum diameter measurement value as the target diameter measurement value characterizing the diameter of the equipment pit.

[0055] In other words, in this embodiment, the minimum depth measurement value obtained from multiple measurements is used as the target depth measurement value of the equipment foundation pit. Simultaneously, the maximum diameter measurement value obtained from multiple measurements is used as the target diameter measurement value of the equipment foundation pit.

[0056] As can be seen from the above embodiments, the advantage of this application's solution lies in the fact that the two probes each perform their respective functions, solving the two core problems of depth and horizontal dimensions, with a clear approach. The closed-loop control formed by the combination of a gyroscope and a servo motor ensures the absolute accuracy of the measurement reference, which is the core of high precision. By observing the laser spot, the operator can intuitively judge the condition of the pit wall, providing a user-friendly human-machine interface. Furthermore, the operator can intuitively judge whether the pit wall is vertical by observing the movement of the visible laser spot from the vertical probe on the pit wall. If the spot falls in a straight line, the pit wall is vertical; if the spot deviates, it is tilted. In other words, the beneficial effects of this application's solution include: Safe and efficient: It enables personnel to conduct measurements without entering the pit, significantly reducing operational risks and improving acceptance efficiency.

[0057] High-precision measurement: Improve measurement accuracy through infrared remote sensing technology and algorithm models.

[0058] Easy to operate: The equipment is lightweight and has a user-friendly interface, making it suitable for rapid on-site deployment.

[0059] Highly adaptable: suitable for acceptance scenarios of foundation pits of different shapes and depths.
