Description

Technical Field

[0001] The present invention relates to the technical field of patrol inspection devices, in particular to a field operation patrol inspection device based on laser point cloud real-time modeling technology. Background Art

[0002] In the process of modern industrialization, electricity plays a vital role in all kinds of work today, that is to say, this society is completely inseparable from electricity. The current improvement of informatization has greatly promoted the advancement of digital technology. The work of safe production risk management and control is combined with modern information technology to obtain a safe production risk management and control system, which fundamentally improves the level and ability of safe production management of power grid enterprises.

[0003] In the research of operator behavior detection and illegal target detection in the complex background of substations, in order to ensure the safe operation of substations, substation illegal target detection based on artificial intelligence has been widely used in substations. In the research of on-site safety intelligent technology, the operation of various equipment in substations involves many dangerous areas, live areas and interval control, and the mistaken entry of personnel will cause serious accidents.

[0004] Existing mining inspection devices usually use a hanging form to inspect on the track. The running track is usually I-shaped and set on the top side wall of the mine. Then the inspection device is started to run on the track through the terminal. Due to environmental reasons in the substation, the shape of this track has parallel, uphill and downhill types. Therefore, the inspection device needs to walk uphill and downhill on this track to complete the inspection in the substation.

[0005] However, due to the harsh environment inside the substation, this I-shaped structure is prone to accumulate a lot of dust and dirt on the top and side walls of the mine tunnel. Over a long period of time, this dust and dirt will easily reduce the friction between the track and the inspection device when it encounters water vapor, causing the inspection device to slip during uphill and downhill operations, posing a safety hazard. Secondly, over a long period of time, dust and dirt will easily solidify into hard impurities when it encounters water vapor. If the hard substances are not cleaned in time, the inspection device will shake on the track, affecting the normal operation of the inspection device. Summary of the invention

After acquiring data from two different sensors, the data is firstly fused, and then a series of preprocessing is required for the data. For the preprocessed data, morphological filtering is used to separate ground points and non-ground points. For the ground points, interpolation calculation is performed, and for the non-ground points, feature points are extracted after thinning; corresponding matching points are searched for in the feature points of the two frames of data, and then registration is performed according to the corresponding matching points. After registration, the interpolated ground points and non-ground points are integrated together to render the scene and complete the modeling;

[0054] Data preprocessing module: In the modeling process, after completing the environmental data collection phase, the collected 3D laser point cloud data and radar data are first preprocessed. The preprocessed fused point cloud data is used for subsequent feature extraction and feature matching processes in the modeling experiment;

[0055] Feature extraction module: based on the feature points extracted from the normal vector and the curvature feature points extracted from the curvature, the two feature points are extracted separately, compared, and the appropriate points are selected for subsequent registration;

[0056] Matching modeling algorithm module: Whenever a frame of data is collected from the environment, the newly collected data is transformed into a coordinate system and matched with the previously collected data. When establishing a baseline map model, a satellite positioning system is used to obtain multiple control points for posture settlement, and the collected color point cloud data is given location information. The point cloud data registration algorithm uses the normal distribution transformation algorithm and the iterative nearest neighbor algorithm.

[0057] The preprocessing of the data preprocessing module includes: conversion of the point cloud data coordinate system, fusion of point cloud and color image data, establishment of spatial index of fused data, elimination of gross errors of point cloud, morphological filtering and thinning of point cloud data.

[0058] It also includes an I-shaped track 2, the inspection device body 1 is installed on the I-shaped track 2, a plurality of driving rollers 3 in a rectangular array are installed on the top of the inspection device body 1, and the plurality of driving rollers 3 are rollingly connected on opposite sides of the I-shaped track 2, an auxiliary roller 31 is installed on the top wall of the inspection device body 1 and between the driving rollers 3 at the front and rear ends, the auxiliary roller 31 is rollingly connected on the bottom wall of the I-shaped track 2, a plurality of first cleaning components 4 are arranged on the left and right ends of the inspection device body 1, and are used to clean the dust on the inner side of the I-shaped track 2 during uphill or downhill operations, the first cleaning component 4 includes a rotating member 41 arranged on the left and right ends of the inspection device body 1, a fixing rod 42 is installed on the side of the rotating member 41 away from the I-shaped track 2, a connecting plate 43 is installed on the side of the fixing rod 42 away from the rotating member 41, and a dust box is rotatably connected to the top of the connecting plate 43 44. A quick-disassembly box 441 is provided at the bottom of the dust box 44. A circular cover 45 is installed at one end of the dust box 44 close to the I-shaped track 2. The dust box 44 and the circular cover 45 are connected. A U-shaped connecting block 46 is installed on the side of the circular cover 45 close to the inspection device body 1. A cleaning plate 47 is installed at the end of the U-shaped connecting block 46 away from the circular cover 45. A side plate 48 is installed at the end of the cleaning plate 47 away from the circular cover 45. The cleaning plate 47 and the side plate 48 are both slidably connected on the inner side of the I-shaped track 2. The cleaning plate 47 is located on the opposite side of the inspection device body 1 and is inclined. The cleaning plate 47 is located on the opposite side of the I-shaped track 2 and is slightly inclined outward. The side plate 48 is located on the opposite side of the inspection device body 1 and is inclined. The circular cover 45 is inclined, and one end of the cleaning plate 47 protrudes from the outside of the I-shaped track 2 and extends into the inside of the circular cover 45.

[0059] During operation, when the driving roller 3 and the auxiliary roller 31 drive the inspection device body 1 uphill or downhill, due to the self-gravity of the circular cover 45 and the cleaning plate 47, the cleaning plate 47 and the side plate 48 slide on the inner side of the I-shaped track 2. First, the side plate 48 can clean the dust on the side wall of the I-shaped track 2, and the cleaned impurities will fall on the cleaning plate 47. At the same time, the cleaning plate 47 can clean the dust on the bottom surface of the side where the driving roller 3 contacts the I-shaped track 2. Then, under the pushing pressure of the cleaning plate 47, the dust flows into the inner side of the circular cover 45, and then flows into the dust collection box 44 and the quick-disassembly box 441. It can be cleaned by the staff later. The dust on the I-shaped track 2 can be cleaned under the power of the inspection device body 1 to avoid reducing the friction between the driving roller 3 on the inspection device body 1 and the I-shaped track 2.

[0060] It is worth noting that the cleaning plate 47 provided in the present invention is located on the opposite side of the inspection device body 1 and is inclined, which is conducive to the rapid cleaning of dust on the bottom surface of the I-shaped track 2, so that the dust flows in through the top surface of the cleaning plate 47. At the same time, the cleaning plate 47 provided in the present invention is located on the opposite side of the I-shaped track 2 and is slightly inclined outward, which is conducive to the dust on the top surface of the cleaning plate 47. Under the pressure of movement, the dust can be quickly thrown out from the cleaning plate 47 toward the inner side of the circular cover 45 to prevent the dust from falling on the I-shaped track 2 during the movement of the inspection device body 1, and can also accumulate the dust.

[0063] When the inside of the quick-detachable box 441 is filled with dust, the staff can rotate the rotating plates 443 on both sides outward to allow the clamping block 444 to be separated from the wedge block 442, and then detach the quick-detachable box 441 from the dust box 44 so that the dust in the quick-detachable box 441 can be processed. This makes it convenient for the staff to quickly install or disassemble the quick-detachable box 441, and greatly improves the efficiency of dust processing.

[0074] Embodiment six:

[0075] The technical solution is basically the same as that of the first embodiment, except that Fig. 9 , Fig.12 and Fig.12 As shown, a micro spring (not shown in the figure) is connected between the connecting balance plate 50 and the inspection device body 1, a control rod 501 is rotatably connected to the middle part of the connecting balance plate 50, an artificial twisting cap 502 is installed at the end of the control rod 501 away from the inspection device body 1, a pair of limiting arc parts 503 are installed in the middle part of the connecting balance plate 50, a pair of limiting control parts 504 are installed on the side of the artificial twisting cap 502 close to the connecting balance plate 50, and the pair of limiting control parts 504 are just passed through the pair of limiting arc parts 503, an outer wall of the limiting rod 52 is provided with an avoidance groove on one side relative to the inner disk gear rod 541, the blowing rod 561 and the brush cylinder 57 are fixedly connected by a twisting rod, and a rubber pad is installed on the side of the blower 56 close to the brush cylinder 57.

[0076] During operation, when it is necessary to replace the brush cylinder 57 and repair the electric heating plate 560 inside the blower 56, the staff turns the manual twisting cap 502 to make the limit control part 504 disengage through the gap between the limit arc parts 503, so that it is convenient for the staff to pull the connected balance plate 50 and the buffer rotating plate 53 connected to it to move outward, and at the same time, the inner disk gear rod 541 slides along the inner side of the avoidance groove on the limit rod 52, so that the staff can disassemble the brush cylinder 57 and the blower 56 and repair the electric heating plate 560 inside the blower 56.

[0077] It is worth noting that the limit control member 504, the limit arc member 503 and the micro spring provided in the present invention cooperate to achieve locking or quick disassembly of the connecting balance plate 50, which is convenient for the later installation of the brush tube 57. It is only necessary to press the connecting balance plate 50 to move along the manual twisting cap 502, and then rotate the manual twisting cap 502 so that the limit control member 504 is squeezed on the limit arc member 503, thereby improving its installation or disassembly efficiency.

[0078] Working principle: This is a mining inspection device. When in use:

[0079] First: during operation, when the driving roller 3 and the auxiliary roller 31 drive the inspection device body 1 uphill or downhill, due to the self-gravity of the circular cover 45 and the cleaning plate 47, the cleaning plate 47 and the side plate 48 slide on the inner side of the I-shaped track 2. First, the side plate 48 can clean the dust on the side wall of the I-shaped track 2, and the cleaned impurities will fall on the cleaning plate 47. At the same time, the cleaning plate 47 can clean the dust on the bottom surface of the side where the driving roller 3 contacts the I-shaped track 2, and then, under the pushing pressure of the cleaning plate 47, the dust flows into the inner side of the circular cover 45, and then flows into the dust collection box 44 and the quick-disassembly box 441, and can be cleaned by the staff later. The dust on the I-shaped track 2 can be cleaned under the power of the inspection device body 1 to avoid reducing the friction between the driving roller 3 on the inspection device body 1 and the I-shaped track 2.

[0080] Second: when the inside of the quick-detachable box 441 is filled with dust, the staff can rotate the rotating plates 443 on both sides outward to make the clamping block 444 break away from the constraint on the wedge block 442, and then detach the quick-detachable box 441 from the dust box 44, so as to deal with the dust in the quick-detachable box 441.

[0081] Third: When the inspection device body 1 is moving, the supporting roller 401 on the rotating part 41 connected thereto rolls on the bottom wall of the I-shaped track 2. At the same time, under the pressure of the reset spring 412, it is conducive to the circular cover 45, the U-shaped connecting block 46 and the cleaning plate 47 to enter the uphill or downhill state on the I-shaped track 2, and at the same time, it does not affect the cleaning of the cleaning plate 47 and the side plate 48 on the inner side of the I-shaped track 2. When the inspection device body 1 is moving, the ball 473 rolls inside the groove 474, and the slider 472 connected thereto can make the first compression spring 471 maintain a balancing force, so that the cleaning plate 47 remains parallel to the bottom surface of the I-shaped track 2 during the uphill or downhill process, and at the same time, the cleaning plate 47 is effectively close to the bottom surface of the I-shaped track 2.

[0082] Fourth: When there are hard impurities on the bottom surface of the I-shaped track 2, the kinetic energy of the driving roller 3 is utilized, and the rotating shaft connected thereto drives the limiting rod 52 to rotate, thereby driving the inner disc gear rod 541 and the driving gear 54 connected thereto to rotate, and then driving the passive gear 55 and the blower 56 to rotate, and the brush on the brush tube 57 can clean the hard impurities on the I-shaped track 2, and then, under the pressure of the blower 56, the air flow flows into the injection port 563 and flows out of the air injection port 571, so as to blow away the hard substances to prevent the substances from hindering the movement of the inspection device body 1, and the present invention is provided with an electric heating plate 560 and a heating wire 562, so that after the dust is cleaned, if there is still some dust on the bottom surface of the I-shaped track 2, it can be blown dry with the cooperation of the electric heating plate 560 and the heating wire 562, so as to facilitate the later cleaning of the dried dust.
