Example 2
As shown in fig. 7, exemplary embodiments of the method for locating railroad tie positions of the present invention comprises the steps of:
s101) when the railway track is positioned at the starting point of the railway track, the railway track sleeper position measuring device 100 positions the kilometer post to the starting point;
s102) the railway line sleeper position measuring device 100 starts to measure along the railway line, moves the kilometer post forwards, marks the center position of the sleeper 10 when the sleeper 10 is detected, and marks the corresponding kilometer post;
s103) when the obstacles 16 exist between the sleepers 10, marking the obstacles between the two sleepers 10 and marking corresponding kilometer marks;
s104) when detecting that the joint 17 exists between the two rails 13, marking a rail joint mark between the two corresponding sleepers 10 and marking a corresponding kilometer post;
s105) repeating steps S102) to S104) until the railway line measurement is finished, and forming a data file of the correspondence relationship between the tie 10 and the kilometer post.
The railroad track tie position measuring apparatus 100 further includes a measuring module 1, and a measuring wheel 2, a magnet sensing switch 3, a th proximity switch 4, and a second proximity switch 5 connected to the measuring module 1. in step S102), when the magnet sensing switch 3 and the th proximity switch 4 detect a spike 11 on a tie 10 while the second proximity switch 5 detects the tie 10, the measuring module 1 judges that the tie 10 is detected, marks the railroad track mileage measured by the measuring wheel 2 as a metric scale of the corresponding tie 10, and forms railroad track data for guiding the operation of the track tamping vehicle.
As shown in fig. 10, a schematic diagram of the principle of measuring the tie position using the railroad track tie position measuring device 100 of the present embodiment, to accurately determine the position of ties 10, it is assumed that three probes (i.e., the magnet sensing switch 3, the th distance proximity switch 4, and the second distance proximity switch 5) measure the high level simultaneously and the level width corresponds to the physical size , in order to further increase the accuracy of the detection by steps, the railroad track tie position measuring device 100 may also include more probes, and the tie position measuring device 100 may include three probes simultaneously measure the high level at the marking point A, C, D, E, F and the width corresponds to the physical size , so that it is possible to mark its specific position on the corresponding kilometer marker, while at the marking point B, the th distance proximity switch (probe 2)4 detects a high level width greater than the physical width, for detection with an error, the result of the proximity switch (probe) 3 and the second distance proximity switch probe (probe 3) is combined, the intelligent measurement result of the proximity switch 355 is filtered, and the tie position measuring data is filtered at the marking point 3515, the marking point B, the tie position measuring device 3510, thus the tie position measuring device detects the tie position of the tie 10 directly at the marking point B, and the tie position measuring device 3510, and the tie position measuring device is filtered by the magnetic track marking point B, thus the magnetic track marking device 355, which is not satisfied with the magnetic track marking point B, the magnetic sensing device 3510.
In step S102), when the magnetic inductive switch 3 and the -th proximity switch 4 respectively detect a sensing signal indicating the presence of the spike 11, and the level width of the sensing signal corresponds to corresponding to the dimension of the spike 11 along the length direction of the railway track, and the second proximity switch 5 detects a sensing signal indicating the presence of the tie 10, and the level width of the sensing signal corresponds to corresponding to the dimension of the tie 10 along the length direction of the railway track, the measuring module 1 determines that the tie 10 is detected, and when the measuring module 1 detects the tie 10, obtains the center point of the tie 10 along the length direction of the railway track, and scales the data of the center point onto the corresponding kilometer scale position information, which indicates that ties 10 exist at the center point, and the center points of two adjacent ties 10 are the position for inserting the railway track tamping vehicle.
In step S103), when the measuring module 1 detects that there is an obstacle 16 between the sleepers 10, the data of the obstacle 16 is calibrated to the corresponding kilometer sign position information, and an obstacle mark indicating that the position prohibits the tamping vehicle from tamping and inserting.
In step S104), when the measuring module 1 detects that there is a joint 17 between two rails 13, the data of the joint 17 is calibrated to the corresponding kilometer sign position information, and a rail joint mark is added to indicate that the position is a rail joint.
Between step S102) and step S105), a step further includes the steps of:
when the measuring module 1 detects that the non-line feature 18 exists between the two steel rails 13, the data of the non-line feature 18 is calibrated to the corresponding kilometer sign position information, and a non-line feature mark is added to indicate that the position is the non-line feature 18, so that the non-line feature 18 can provide kilometer sign synchronous point information for the next railway line measurements.
In step S102), when the railroad track tie position measuring device 100 measures the railroad track, the processing unit 6 synchronizes the map of correspondence between the tie 10 of the virtual actual railroad track and the kilometer post for the operator to review and review the data, and when the railroad track measurement is completed, a complete database operation file is formed.
In step S102), when the measuring module 1 does not measure the center point of the tie 10 and a certain position of the railway line requires the center point position information of the tie 10, the center point mark of the tie 10 is manually added by the processing unit 6.
In step S105), the measurement module 1 analyzes and calculates the measured railroad track data to obtain distance data including an average distance, a minimum distance and a maximum distance between 2 to X sleepers 10, where X is greater than or equal to 3 and less than or equal to N, and N is the number of sleepers of a certain continuous measurement section of the railroad track.
In step S102), when the railway line has bad measuring conditions and all sleepers 10 cannot be detected, the measuring module 1 manually sets the number of exempt sleepers by using a fuzzy measuring method, and measures sleepers 10 at intervals of sections, when the number of the exempt sleepers manually set is X, sleepers 10 must be detected within the maximum distance of the X sleepers 10, and if no sleeper 10 is detected beyond the maximum distance of the X sleepers 10, the measuring module 1 sends out an alarm signal, when the distance between the current position of the measuring point of the railway line sleeper position measuring device 100 and the position of the measuring point of the upper measured sleepers 10 is between the minimum distance of the X sleepers 10 and the maximum distance of the X sleepers 10, it indicates that there are X sleepers 10 between the two measuring points, and the measuring module 1 averagely places X sleepers 10 between the two measuring points, and then forms a virtual line operation file.
When the railway line is in a poor measuring condition and all the sleepers 10 are not detected, the measuring module 1 manually sets the number of exempt sleepers by fuzzy measurement, and the distance between every two adjacent sleepers 10 is , when the number of the exempt sleepers manually set is X, sleepers 10 must be detected within the maximum distance of X sleepers 10, if the maximum distance of the X sleepers 10 is not detected, the measuring module 1 sends out an alarm signal, when the distance between the current measuring point position of the railway line sleeper position measuring device 100 and the measuring point position of the sleeper 10 measured in the last times is between the minimum distance of the X sleepers 10 and the maximum distance of the X sleepers 10, the measuring module 1 places X sleepers 10 between the two measuring points on average, and then forms a virtual line operation file, if the maximum value of the exempt sleepers is set to be 5 manually, the maximum distance between the sleeper 3025mm distance is within the maximum distance of 395 mm, 56 sleepers 10 can be detected, if the distance between the two measuring points is detected and the track 10 is detected and the virtual line operation file is found to be found, then the distance between the railway line sleeper 10 is found to be a virtual line operation file, if the distance between the track operation file is found to be found by fuzzy measurement error, then the track operation module 10, the virtual line operation file is found to be found by checking if the track operation file, the track operation of the track operation module 10, then the track operation of the track operation module 10.
When all of the railroad track tie data is required, the exact location information for each tie 10 can be measured using precision measurements. In the fuzzy measurement mode, if the position information of the sleeper 10 which is not measured exists, the measurement module 1 extracts and analyzes the information of the measured railway line, automatically calculates and supplements the position information of the missing sleeper 10, or manually supplements the information of the missing sleeper 10. The selection of the manually set maximum no-test sleeper value is usually much smaller than the calculated maximum no-test sleeper number (when the maximum distance of the xth sleeper is greater than the minimum distance of the xth sleeper +1, the minimum value of X-1 is the maximum no-test sleeper number, and the maximum no-test sleeper number in fig. 8 is 22). Therefore, in order to obtain more accurate track line data, the maximum non-measuring number of the sleepers manually set for the track line with larger distance error of the sleepers 10 is usually smaller, and an operator can adjust the setting in real time according to actual conditions.
In a specific railroad track survey process, when 3 probes of the railroad track tie position measuring device 100 measure a high level at the same time (i.e., detect both tie 10 and spike 11), ties 10 can be determined, and when only probes measure either tie 10 or spike 11, a false measurement is possible, data as shown in fig. 8 can be used to deduce and verify whether the measured tie 10 is correctly located, for example, obstacles 16 are detected between ties 10 by probes, if the current location is 2000mm from the previous ties 10, data indicating that the current location is between 3 max and 4 min tie spacing, it cannot be determined whether 3 or 4 ties 10 are placed within the distance, the location is not marked as the tie 10 location, and the railroad track position measuring device 100 generates an alarm signal to remind the operator to verify the data.
In fig. 9, all of the tie 10 information is labeled on the corresponding kilometer scale (or mileage), the barriers 16 between the ties 10 are labeled with the label ①, identifying that tamping is not possible here, and the joints 17 of the rails 13 are labeled with the label ②. when a track tamping vehicle is operating, it is not necessary to measure the barriers 16 and the joints 17 of the rails 13, but rather, the kilometer scale (or mileage) position locating marks ① and the labels ② are used directly, the labels ③ (other labels) are not characteristic of the actual railway line (e.g., a wayside utility pole, or a line mileage mark, etc.), indicating that something is present beside the railway line, its position between some two ties 10, and its role is to provide kilometer scale (or mileage) synchronization points (or reference points) for the next measurements-likewise, every ties 10, and every marking points, can be used as synchronization points.
After the specific measurement by the railroad track tie position measuring device 100, the resulting track file may be:
the method for positioning the sleeper position of the railway track described in the embodiment can accurately measure and position the specific position of the sleeper 10 by using the position height relation of the sleeper 10, the rail nails 11 and the ballast 12, and mark the positions of the barriers 16 and the joints 17 of the steel rails 13. after a track tamping vehicle obtains a position track file of the sleeper 10, automatic tamping operation can be realized.A track sleeper position positioning method of the invention can replace a method of manually stepping on a pick by an operator, automatically give a tamping head descending signal, and realize large-scale engineering machinery automatic operation.A track sleeper position positioning method described in the embodiment can accurately measure an unknown railway track, and after the measurement is completed, obtain a track data file track tamping vehicle to perform specific operation, can accurately position the specific position of the sleeper 10, calculate the moving distance from the current position to the lower operating position, completely replace a related post operator, count the number of the sleepers 10 and the steel rails 13 of the railway track within a distance of , meanwhile, obtain the specific position of the sleeper 10 by measurement, position information of the sleeper 10 is positioned to the lower operating position of the railway track, and finally calculate the number of the track sleeper 10 and form effective track tamping operation data file (after the track tamping operation, and the track tamping operation can be calculated by adopting the track tamping operation method, and the track tamping operation can accurately measure the track tamping operation without the track tamping operation data file, and the track tamping operation can be used for the track tamping vehicle to measure the track tamping operation without the track tamping operation.
