4.3 "frock is checked school": the common tool and the sensor tool are calibrated and corrected, and the function is changed to be only suitable for a standard frame type tool, and the common tool and the sensor tool are often used for fine adjustment of a track plate of a high-speed rail project and are not suitable for a screw hole type single-hole tool.
4.4 "communication test": for setting communication parameters between components of system, including setting of display handbook and total station radio station
5 'fine adjustment operation': the method comprises the following functional options of communicating a measuring function, turning to an upper plate, a lower plate, a plate lap plate and the like.
5.1 "fine tuning": including regular measurement and fast measurement modes. All measurement modes support continuous clicking, namely, clicking for several times of measurement, and software continuously executes several times of measurement (in a single-point measurement mode, the number of clicks is equal to the number of clicks of measurement, and continuous measurement can also be realized; in a rapid measurement mode, uninterrupted measurement can be realized by only once point measurement after selection). All measurement modes can be manually stopped with a "stop button". In the measurement mode, the displayed mileage is a continuous mileage.
Note that: the order in which the measurements are performed in the fast measurement mode is: and (3) measuring the tool prism (currently, point 1) of the sensor four times, then automatically converting to once to finish the measurement, and then measuring the point position … … of the sensor four times until clicking to stop. The mode suggests that the adjustment amount of each point of the board is used in millimeter level, which can improve efficiency.
Add the display function, show the handbook data on external display, make things convenient for the accurate adjustment workman to look over the data to in time adjust, work efficiency is accelerated to a certain extent.
5.2 "options": the method is used for setting functions such as calculation mode, operation direction, file name storage, laser opening and closing and the like.
5.2.1 route calculation: the combination of the left and right line planes and the left and right line longitudinal slopes can be selected for use, and a single project single parameter file is suggested, namely, the left line plane and the left line longitudinal slope are placed in a project, and a left-horizontal left-high mode is used. (default left flat left high is recommended) 5.2.2 job direction: the advancing method of the instrument can also be understood as that the direction from the prism to the instrument is from a small mileage to a large mileage or from a large mileage to a small mileage, wherein the former is a large mileage and the latter is a small mileage.
5.2.3 operation step length: i.e. plate length, which is automatically assigned after the plate type is selected at the fine tuning interface.
5.2.4 store filenames: name of file to be stored (the file stores the current stored tuning board information)
5.2.5 Broard filename: the board information can be edited by 'line calculation software' in advance and imported into a manual book for automatically identifying the board type on site, and when no file exists, the corresponding board type needs to be manually switched
5.2.6 Total station laser: for switching the total station laser on or off.
5.2.7 laser of tool: for turning the tool laser on or off (the tool laser is used to adjust the sensor axis).
5.2.7 Manual sighting P1: when the measurement is performed for the first time in error (No. 1 is not aligned, so that the point 1 measured by the software is incorrect), the item can be selected without withdrawing the measurement interface, and the correct point position is realigned to perform the measurement again. Otherwise, the interface of the fine tuning operation needs to be quitted.
5.2.8 number of consecutive measurements: after setting the number of times of continuous measurement, the four-corner measurement mode is automatically switched to.
5.3 "station change": after the station changing, the station changing precision is not enough, so that the difference between the measured plate data of the two stations is too large (2 mm). The automatic measurement and automatic correction lapping value of the supporting instrument and the manual input of the required lapping value are also supported.
5.4 "check": the method is used for checking whether the station change value is reasonable or not after station change lap joint; and the method is also used for checking whether the continuous mileage calculated in fine tuning corresponds to the broken link mileage under the interface. The bubble function is used for reading the LT value of the total station and judging whether the instrument needs to be reset.
5.5 "one plate on top": the method can be used for returning to the upper board, and after the upper board returns, the measurement can be clicked, and the interface jumps to a fine adjustment interface; in addition, the lap joint value and the display value of the previous block can be cleared.
6 "calculation tools": and performing a small tool for calculating five piles and the forward and backward calculation of the mileage coordinates under the current project parameters.
7 "software registration": and registering the software.
8 "exit": the software is exited.
