Description

Engineering measurement paying-off method and system

Technical Field

The invention relates to the technical field of constructional engineering, in particular to railway engineering measurement, and particularly relates to an engineering measurement paying-off method and system.

Background

The engineering paying-off is a technical process for projecting horizontal and vertical lines and oblique lines on a design drawing to an actual construction engineering object. The method is a basic projection form of geometric figures in construction and dismantling, has the advantages of simple operation, short steps, rapid projection and the like, and is an important tool and a technical means for rapidly and accurately analyzing and projecting in construction and dismantling. The engineering paying-off implementation can enable the entity to keep consistent with the design drawing, and not only can the line in the design drawing be projected onto the entity, but also the mark on the drawing can be projected onto the entity. The implementation steps comprise:

(1) Precondition of line: the positioning is accurate, and the positions of the rod, the column and the wall surface are accurate;

(2) Positioning lines:

drawing a horizontal line on a physical positioning point by using a pencil through a level gauge, measuring the length of the horizontal line according to the distance between the positioning lines on a design drawing, and finally forming a complete horizontal line body; then, drawing one (or two) horizontal lines to form grid lines, wherein the distance between the grid lines is consistent with the distance between the positioning lines on the design drawing; immediately after that, diagonal lines are drawn.

(3) Positioning and marking: marking the position of the positioning grid on the entity, and marking by using a engraving die or diamond; then positioning the relative positions of the beams, the wall surface columns and the rods on the horizontal line, and marking the relative positions on the entity; thirdly, marking the end point coordinates of the beams, the wall surface and other columns and rods on the entity according to the specific requirements on the design drawing; finally, the horizontal line and the oblique line are marked on the entity.

The prior art generally uses total stations for construction lofting measurements, such as rubbing total station GTS-2002 or south total station NTS-332R, etc., however, the current total station has various defects, such as:

(1) Because the hand calculation of the polynomial, the power of the square and the data related to one coordinate are large, and almost several hours are spent, the current total station cannot calculate the moderation curve offset;

(2) The reference arc and reference line functions can obviously improve paying-off efficiency, particularly can bypass some barriers, and have the advantages of less input coordinates and less number of times of rod moving by rod running staff, however, the rubbing total station GTS-2002 has no reference arc function, and the southern total station NTS-332R has no reference line function;

(3) The existing total station adopts Excel programming and Cassie European programming, so that some fatal BUG exists, for example, input arc radius cannot be forbidden to be smaller than 0, and Cassie European cannot assist measurement through display graphics;

(4) The existing total station is inconvenient to input and check data by using personnel, and the input data cannot be automatically converted into data types directly participating in computer recognition calculation;

(5) A large radius total station cannot use a reference arc. Such as the comes total station TS09 plus, the highest supporting radius is 9999.9999 meters, while the arc of the basic station of the suburban station of the jingtang railway is 10007.7550m, so the reference arc function of the total station cannot be used in this case.

(6) The current total station has no proper prompting and alarming function, for example, when the offset is close to 0 or equal to 0 (namely, a prism rod just stands on a designed line and has no corresponding prompting, the paying-off efficiency is low, for example, the direction of the offset is not displayed, the relation between an arc and a circle has no text prompting, and the relation between the arc and the circle has signs only and needs manual conversion, so that the efficiency of a person looking a mirror for commanding a running rod person to move the prism rod is low;

(7) The method is characterized by lacking the functions of optimal circular arc graphical selection, auxiliary switching from a paying-off mode to a paying-off mode by a starting and ending point coordinate exchange function, line internal industry pretreatment, azimuth angle display function (for error checking), graphic display position relation function (for error checking, convenient for commanding a running staff to move positions), line storage function (which is beneficial to paying-off for a plurality of times, line switching and error checking after the fact is facilitated), parallel line function (as long as the line is parallel to the line and has a deviation distance knowing function, the function of inputting a line coordinate and can be used for paying off a plurality of parallel lines, and the specific application is that a building is paying off a plurality of parallel axes) and line dragging function.

(8) The mobile phone Bluetooth cannot be connected with the total station, the total station measurement cannot be controlled at the mobile phone end, the measurement coordinates cannot be automatically acquired and calculated, and figures and characters cannot be output, so that the measurement speed and accuracy are reduced.

(9) The method has no functions of paying off and calculating of circular arcs, circles, relaxation curves (paying off), relaxation curves (collecting), paying off surfaces and circle centers, and has limited application scenes.

Therefore, there is a need to develop new engineering survey paying-off methods and systems, add additional functions required in numerous application scenarios, and optimize computing, display, and measurement modes.

A third aspect of the invention provides an electronic device comprising a processor and a memory, the memory storing a plurality of instructions, the processor being for reading the instructions and performing the method according to the first aspect.

A fourth aspect of the invention provides a computer readable storage medium storing a plurality of instructions readable by a processor and for performing the method of the first aspect.

The method, the system, the electronic equipment and the computer readable storage medium provided by the invention have the following beneficial technical effects:

(1) The problem of calculate and alleviate curve offset difficulty is solved, with this APP back, can accomplish in the twinkling of an eye to can be accurate within 1 mm.

(2) The problem that a total station with a partial model does not have a reference line and reference arc function is solved. After the APP is used, the APP can be applied to any total station.

(3) Some of the BUGs, some of the shortages of the cassie programming and BUGs brought about by Excel programming are avoided. For example, the radius of the input arc can be forbidden to be smaller than 0; carxiou cannot assist in the measurement by displaying graphics.

(4) An angle input and computer interaction mode is invented. For example, inputting 10°00'02.34 "(10 degrees 0 minutes 02.34 seconds), there are problems: firstly, the mobile phone is inconvenient to input the symbol of the symbol, and secondly, the data after input is processed, computer "don't know" cannot be used directly for calculation; third, the degree, the fraction and the integer part of the second are 60 scale, and the fraction part of the second is 10 scale and the calculation logic is complex. The method of the invention is convenient for the user to input data and also can be convenient for checking, and the input data can be directly recognized by a computer and participate in calculation after being automatically converted, can be immediately converted into true angle data of the computer and can be converted into data capable of participating in computer calculation.

(5) The problem that the reference arc cannot be used by the large-radius total station is solved. For example, the total station TS09 plus of the Leika has a highest supporting radius of 9999.9999 m, while the arc of the basic station of the suburban station of the Beijing Tang railway is 10007.7550m, and the reference arc function of the total station cannot be used. The arc of the radius can be put by using the arc function of the APP.

(6) When the offset is close to 0, or equal to 0 [ equal to 0, i.e. the prism rod just stands on the designed line ]. When the prism rod exceeds the design line (taking the recorded coordinate data as a reference), the exceeding prompt is prompted, and a specific numerical value is displayed. Because the more exceeded, the less accurate. Offset displays "left and right", circular arcs display "near center of circle", far from center of circle ", they only display signs as compared to a certain model total station or program. This function improves the efficiency with which a person looking at the mirror instructs the pole running person to move the prism pole.

(7) Because the arc calculation process has the root, the mathematical solution can calculate two different circles, and the APP is displayed in an auxiliary mode through the graph, so that a measurer can conveniently and quickly judge which circle should be discarded.

(8) When the linear coordinates are modified, the function of exchanging coordinates is provided, and the coordinates of the starting point and the ending point can be exchanged, so that the function is beneficial to switching from a paying-off mode to a paying-off mode [ when the offset distance and the mileage are both 0, namely, the starting point position is played out ].

(9) The lines can be stored for a plurality of lines, so that the line can be treated in advance, and the speed of paying off in the field is increased.

(10) Besides the function of inheriting the display mileage and offset, the following aspects are optimized: azimuth angle (for error checking) is displayed, position relation is graphically displayed (for error checking, the movement of a running staff person is facilitated), lines are saved (multiple paying-off and line switching are facilitated, error checking after the fact is facilitated), parallel line functions (as long as the parallel line is parallel to the line and the offset distance is known, the parallel line has the function of inputting a line coordinate, and a plurality of parallel lines can be put, and the parallel line is particularly applied to putting a plurality of parallel axes of a building); the line dragging function can be used for putting the line to a 'handy' position, so that paying-off or error checking is facilitated.

(11) The mobile phone Bluetooth is connected with the total station, the total station is controlled to measure at the mobile phone end, then the coordinates obtained by measurement are automatically obtained and participate in calculation, finally characters and graphs are output (the mobile phone, the total station and the coordinate calculation are organically combined, the measurement speed is improved, the occupied time of manually copying the coordinate data is long, errors are likely to occur, after the Bluetooth is used, the obtaining time of each coordinate (XY coordinates average about 20 digits) is about 3-4 seconds, and the accuracy is improved.

(12) The arc-placing function solves the problem that the reference arc function of the Leka total station cannot be amplified to the radius of 10000 meters. The arc radius of the platform of the suburban station is about 10007 meters, so that the reference arc line of the picnic station cannot be directly inferred. And through the display and the switching of the graph, the paying-off is assisted.

(13) In the rounding function, the offset distance is not simply displayed positive or negative, but "close, or far, and good" is displayed according to the situation. The circle can be stored, the coordinates do not need to be input again when paying off for many times, the coordinates are checked correctly once, and 100% of the coordinates defined next time can be ensured to be correct. Meanwhile, circles with different concentric radiuses can be measured, and only the offset distances are consistent.

(14) The pay-off and pay-off relaxation curve provides a function of calculating coordinates of mileage back calculation and has a function of calculating coordinates of left and right piles; the relaxation curve can be collected and collected, a straight line and an arc nearby the relaxation curve can be simultaneously placed, a keyword of a straight line section reminds the straight line section, a keyword of a keyword close to the center of a circle and far from the center of a circle reminds the arc section, the relaxation curve section reminds a keyword of a left deviation and a right deviation, and the keyword can improve the speed of a measurer who 'looks at a mirror' to command a running staff, because the measurer does not need to think about the rod on the straight line section, the arc or the relaxation curve again. The position of the measuring point is displayed graphically, so that a measurer can conveniently meet the ground of a professional construction team, and the measurer can conveniently arrange bricks and lay the ground, retract according to arrangement limit, and have ultrahigh outer rail and the like.

(15) The 'placing surface' solves the problem that the design elevation of a certain stone is difficult to solve by the two-way Fang Po of the platform surface of the high-speed railway (namely, placing slopes along the track direction and along the direction vertical to the track respectively). The circle center coordinate is calculated, so that the problem of measuring the circle center of the existing cylinder of the old railway station house is solved. The stored coordinates function of this function can also be used to collect terrain coordinates. After the mobile phone app is stored, the mobile phone app can be directly shared with other carriers for reprocessing through third party software such as WeChat, QQ and the like. The problem that some old total stations are not properly driven in connection with a computer, or data wires are lost or damaged, and data transmission is unsmooth, data transmission is slow, and the special U disk is not recognized is solved.

Detailed Description

The following describes in further detail the embodiments of the present invention with reference to the drawings and examples. The following examples are illustrative of the invention and are not intended to limit the scope of the invention.

As shown in fig. 1, the present embodiment provides an engineering measurement paying-off method, including:

As a preferred embodiment, the measurement options of the S2 include: put straight line, put the circular arc, put circle, put lofting relaxation curve, put and gather relaxation curve.

As a preferred embodiment, for straight line, the engineering survey pay-off application includes:

Wherein, the 1 meter line parallel to the building axis refers to the positioning of the building by the building axis in the actual lofting process, and objects such as posts which often obstruct the paying-off are arranged on the axis. Therefore, translating the building axis out of 1 meter tends to bypass these obstacles, commonly known as "1 meter lines"; the lines of 0.5m, 0.3m and 0.2m … … are called 1 meter, because 1 meter is an integer, the calculation is convenient, and the error checking is also convenient after the fact.

Compared with the function of linear setting of a theodolite, the function of linear setting of the engineering measurement paying-off application program has the advantages that:

(1) the total station is not required to be arranged right above the straight line, so that the interference of obstacles on the straight line can be avoided.

(2) The station moving is more convenient, if the straight line is overlong, the station moving is needed, and the total station is only needed to be erected at a place which is in sight with the straight line and the rear view point, so that a measurer can select more measuring positions, and the measuring is more convenient.

Compared with the function of dotting and putting straight lines by using a total station, the engineering measurement paying-off application program has the advantages that:

(1) the original data is only required to be input once, and the control point (except for the places with barriers) can be almost arbitrarily encrypted in the middle.

(2) If a plurality of straight lines parallel to each other are required. Only one coordinate is input, and the offset distance is known. For example, as shown in fig. 2 (a), the building axis, namely the axis a and the axis B, need to be placed, and only the coordinates of the head and the tail on the axis a and the distance between the axis a and the axis B (for example, 6 meters are input into a side pile), and then the axis B is selected to be on the left side or the right side of the axis a. The input of less coordinates can reduce errors and save time.

(3) A straight line perpendicular to the current straight line can be put by inputting the coordinates once.

Such as: the start point coordinates are the coordinates of the a-axis/1-axis intersection point, the end point is the coordinates of the a-axis/8-axis intersection point, and the 2-axis is known to be parallel to the 1-axis with a pitch of 6 meters. Then, the user only needs to create a straight line and input the starting point coordinate, the end point coordinate and the mileage 0. After the A shaft is put, the 2 shafts are put, and the axis of the 2 shafts can be put out only by keeping the mileage (m) of the P point equal to 6. As shown in fig. 2 (b).

(2) Corresponding various reminders are added for various conditions in the process of straightening the line, and the method comprises the following steps:

(1) if the prism rod is not placed on a straight line, but left deviation or right deviation occurs, the reminding comprises a deviation direction and a deviation distance. The software will give the prompt directly as shown in fig. 2 (c).

(2) If the prism rod is placed exactly on the straight line, the software will give the prompt directly as shown in fig. 2 (d).

(3) If the prism rod is placed beyond the starting point A or the ending point B, the software directly gives a prompt as shown in the figure 2 (e); otherwise, prompt: normal.

(4) As shown in fig. 2 (f), the azimuth, the AB length between the start point a and the end point B, and the line name are displayed to assist measurement.

(3) Coordinate calculation of a point to be lofted of the total station is performed by filling coordinates by hand or inputting coordinates by Bluetooth, and the method comprises the following steps:

if the total station does not support Bluetooth, the acquired coordinates of the known points are filled in by adopting a manual coordinate filling mode, and then 'calculation' is clicked to obtain a coordinate calculation result of the point to be lofted.

If the total station supports Bluetooth, the coordinates of the known points are obtained by adopting a Bluetooth coordinate input mode, which comprises the following steps: and binding and connecting Bluetooth, wherein after the connection is successful, the status bar displays the name of the total station, meanwhile, a measurement button is added in a page, the total station is controlled to measure by clicking the measurement button, and the measured coordinates are automatically input into a document frame, and then offset distance, mileage and the like are automatically calculated.

(4) Adding, deleting and checking modification of linear line

Clicking on the "straight line" to enter the straight line selection interface, clicking on the float button in the lower right corner, creating a straight line, as shown in fig. 2 (g);

the coordinates of the start and stop points of the straight line prepared in advance and the mileage are input (the mileage does not require that 0 can be input), and a name is given to the straight line (the search is convenient).

Clicking on "confirm" as shown in fig. 2 (h) will see a new card in the line selection page, and record important information about the line in the card.

If the line is also to be edited again, the "card" can be pressed long, as shown in fig. 2 (i), and the modified page is entered and exited.

As shown in fig. 2 (j), here, the relevant data may be modified, or the straight line may be deleted. After deletion, the line selection page no longer has the line.

Clicking the "dustbin" button in the upper right hand corner will delete all lines.

(5) Entering a pay-off page, comprising: clicking on "card" enters the pay-off page.

As a preferred embodiment, for arc discharge, the engineering survey line discharge application will determine the start point, end point and radius of the arc, including:

(1) Determining an applicable scene: the arc is suitable for circular building. Such as posts, railway station arc platforms, circular roads, etc., are unsuitable or incapable of paying out the center of a circle. For example, the arc of a basic platform is designed with the radius r= 10007.7550m at the suburban station of the jingtang railway. Some total stations with reference arcs are not able to calculate such a large radius. It is therefore difficult to put the arc directly with the programs of these total stations themselves. The APP corresponding to the pay-off application program can be successfully solved by using the engineering measurement pay-off application program.

(2) Adding, deleting and checking improvement of arc line

The user prepares the start point, the end point and the radius of the arc and determines whether the center of the arc is on the left or right, as shown in detail in fig. 3 (a).

(3) Paying-off page entering paying-off arc

After creating a curve, clicking the "card" to enter the loft page, as shown in fig. 3 (b).

(4) Adding multiple reminders

As shown in fig. 3 (c), after the coordinates of the measurement points are input, the positional relationship between the measurement points and the circle is displayed by clicking calculation. If not, the method prompts that please get away from the center xxx and please get close to the center xxx.
