Abstract

The invention provides a processing method of open-pit mine slope monitoring plane data based on a measurement robot. The method comprises the following steps: acquiring open-pit mine slope monitoring basic data acquired by the measurement robot, respectively computing residual error and mean square error of a monitoring point azimuth angle and a monitoring point vertical angle; establishing a gross error screening model, and performing gross error rejection on the azimuth angle data and the monitoring point vertical angle data according to the residual error and the mean square error of the azimuth angle and the vertical angle; determining an orienting azimuth correction value according to a monitoring base point K1 and a rear viewpoint K2, and correcting the orienting azimuth of the measured and filtered monitoring point azimuth angle data according to the orienting azimuth correction value so as to obtain the processed monitoring point azimuth angle; determining a fixed side length correction coefficient of the horizontal distance according to the monitoring base point K1 and the rear viewpoint K2, and correcting the fixed side length of the filtered slant distance data of the monitoring point according to the fixed side length correction coefficient of the horizontal distance so as to obtain the processed monitoring point horizontal distance. By use of the method provided by the invention, the precision of the monitoring basic data based on the measurement robot can be effectively improved.

Description

technical field [0001] The invention belongs to the technical field of slope engineering deformation monitoring, and in particular relates to a method for processing plane data of open-pit mine slope monitoring based on a measuring robot. Background technique [0002] After a long period of mining in open-pit mines, the mining depth has been continuously deepened, and the length of the slope has been continuously lengthened. Many mines are already in the process of deep concave mining. Therefore, landslide accidents occur frequently in open-pit mines, which pose a great threat to the safe production of open-pit mines. [0003] Deformation monitoring based on high-precision total stations has been widely used in deformation monitoring due to its low cost, flexible observation, automation and high-precision technical advantages. In addition, the total station with motor drive and program control combines laser, communication and CCD technology to realize the full automation o...

AI Technical Summary

Problems solved by technology

[0004] The above method has the following problems: (1) The Raida criterion is based on the hypothetical gross error screening criterion with a gross error occurrence probability of 0.3%. The slope monitoring based on the measuring robot is affected by factors such as atmospheric refraction and blasting. The probability of data containing gross errors is much greater than 0.3%, so it is not reasonable to use the Raida criterion as the criterion for gross errors

(2) Ignoring the influence of orientation error on the accuracy of monitoring data

(4) Only the meteorological data of the station is used to correct the length of the ranging light path curve, which has a certain representative error
