Description

Technical Field

[0002] Traditional measuring instruments mainly rely on manual operation to achieve a horizontal state during leveling operations. During this process, operators usually need to use auxiliary tools such as level bubbles and adjustment feet to carefully observe and manually adjust the screws on the instrument base or bracket to center the bubble in the level bubble, thereby judging and meeting the requirements of the instrument level. This manual leveling method not only requires the operator to have certain experience and skills to accurately identify and respond to the slight deviation of the level bubble, but also requires repeated adjustments and calibrations under complex and changing environmental conditions, such as uneven ground or when affected by wind, to ensure the accuracy and reliability of the measurement results.

[0051] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments. It should be noted that the embodiments and features in the embodiments of the present application can be combined with each other without conflict.

[0052] According to one aspect of the present invention, Figure 1-3 As shown, a remote leveling control system for measuring instruments is provided. First, through the light intensity acquisition module, air acquisition module, grayscale acquisition module, coordinate acquisition module, size acquisition module and humidity acquisition module in the data acquisition unit, the light intensity around the leveling device, the concentration of particulate matter in the air, the grayscale value on the captured image, the coordinates of the center point of the foot screw 5, the level 8 and the internal bubble, the circumference of the transmission gear 4 and the humidity information data around the device are respectively collected in real time.

[0053] Then, the collected information data is transmitted and stored, and the information data is acquired and analyzed in real time through the data processing unit to obtain the analysis results, and according to the analysis results, the control command signal is issued to the intelligent control unit through the signal sending module, and the camera control module and the automatic leveling module are used to control the camera image quality of the real-time camera unit and the flatness of the mounting platform 9. In addition, when the analysis result is abnormal, an alarm is sent to the background terminal through the abnormal alarm module.

[0054] Afterwards, the data receiving module in the remote monitoring unit can receive the video of the real-time camera unit and the analysis results of the data processing unit in real time, and display the received information data on the background terminal display screen through the data display module.

[0055] The analysis and judgment module can obtain the light intensity, particle concentration and gray value information data of the surrounding of the leveling device from the data acquisition module, and obtain the camera image index through the analysis of the above acquired data. If:

[0056]

[0057] If photo<1+δ, it means that the camera image is clear.

[0059]

[0060] Then, by comparing the distances between the bubble in the level 8 and each foot screw 5, the foot screw 5 to be leveled first is selected:

[0061] DT=max{dt1,dt2,…,dt s}

[0062] Among them, dt k is the priority index of the kth foot screw 5 to be leveled, is the abscissa of the kth foot screw 5, x1 is the abscissa of the bubble in the level 8, is the ordinate of the kth foot screw 5, y1 is the ordinate of the bubble in the level 8, x0 is the abscissa of the center point of the level 8, y0 is the ordinate of the center point of the level 8, and DT is the priority leveling foot screw 5.

[0064]

[0065] The analysis and judgment results obtained by the analysis and judgment module are used to send a control command signal to the intelligent control unit. Then, the automatic leveling module drives the transmission gear 4 to rotate by controlling the driving motor 3. Under the action of the mutual meshing of the transmission gear 4 and the foot screw 5, the foot screw 5 that is first leveled is regulated. At the same time, according to the number of rotations obtained by the analysis, the transmission gear 4 is controlled to rotate, so that the bubble in the leveler 8 is centered, thereby realizing the control of the flatness of the mounting platform 9, wherein N is the number of rotations of the transmission gear 4, H is the height of the mounting platform 9 that rises or falls when the foot screw 5 rotates one circle, α is the preset conversion coefficient, C is the circumference of the transmission gear 4, μ is the friction coefficient between the transmission gear 4 and the foot screw 5, t is the data collection time, wet i is the humidity around the device to be leveled at the i-th second, wet max is the maximum humidity monitored within time t, wet min is the minimum humidity monitored within time t, is the abscissa of the kth foot screw 5, x1 is the abscissa of the bubble in the level 8, is the ordinate of the kth foot screw 5, y1 is the ordinate of the bubble in the level 8, x0 is the abscissa of the center point of the level 8, and y0 is the ordinate of the center point of the level 8.
