TECHNICAL FIELD OF THE INVENTION
The present invention relates to a multipoint observation system for observing a plurality of observation points having different observation point types in a surveying operation using a total station.
[0002]
[Prior art]
In the surveying work using the total station, since the observation conditions change depending on the type of observation point, first observe the basic point, briefly output the calculation report at the office, and then return to the same site again. It is necessary to go out and observe. When the observation point is an auxiliary reference point (polygonal point / traversal point) and when it is a boundary point, not only the observation method is different, but also the observation data is described, as described in the Ministry of Construction's Public Survey Work Rules. It is necessary to output a notebook having different formats, a multipoint observation notebook and a boundary point observation notebook. In the related art, the surveying work is performed in the following procedure.
[0003]
(A) First, multipoint observation is performed, and a multipoint observation notebook is created by the host computer, and traverse calculation of the multipoint is performed to calculate coordinates of the multipoint. Specifically, for example, in FIG.
1. Going to the site, the total station is set at the reference point P11, and the polygonal point P12 is observed twice.
2. By moving the total station to the observed polygon point P12 and observing the next polygon point P13, all the polygon points P11 to P14 are observed.
3. Return to the office, transfer the observation data to the host computer and output the observation notebook, and then perform traverse calculation to determine the coordinate values of the polygonal points.
[0004]
(2) After that, the boundary point and the protruding point are again observed at the site, the boundary point observation notebook is created by the host computer, and the radiation traverse calculation is performed to calculate the coordinates of the boundary point and the protruding point. In particular,
4. Returning to the site again, a total station is sequentially installed at all of the previously observed polygonal points P11 to P14 to observe the boundary points P21 to P24b and the projecting points Q21 to Q24. The protruding point is set to a point where the boundary point can be seen when there is a boundary point that cannot be seen from the place where the total station is installed, and the protruding point is observed.
5. When the observations of P21 to P24b and the protruding points Q21 to Q24 are completed, return to the office, transfer the respective observation data to the host computer, output the respective observation notebooks, and then perform the radiation traverse calculation to determine the boundary. Determine the coordinate values of the point and the projecting point.
[0005]
(3) When the protruding point is observed, the boundary point is observed again at the site, and the coordinates of the boundary point are calculated by the host computer. In particular,
6. When the protruding point was observed last time, the user goes to the site again and installs a total station at all the protruding points previously observed to observe all the boundary points P31a to P34c which were not observed before.
7. Return to the office, transfer the observation data to the host computer and output the observation notebook, and then calculate the radiation traverse to determine the coordinate values of the boundary points.
[0006]
(4) Observe the current state point again at the site and calculate these coordinates. In particular,
8. Return to the site again, install the total station at the previously observed polygonal points, and observe the current points P41a to P44c where the current features (such as utility poles and guardrails) are located.
9. When the observation of all existing features is completed, return to the office, transfer the observation data to the host computer, find the coordinates of the existing features, and create a current plan using CAD etc. based on the observation data acquired so far. create.
[0007]
As described above, in the conventional technology, it is necessary to separately observe a polygonal point, a boundary point, a protruding point, and an existing point, and it is necessary to go to the same site many times. Due to the fact that it must be installed, there is a drawback that it takes a lot of time for on-site observation work and creation of an observation book, and the work efficiency is extremely poor.
[0008]

BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, a preferred embodiment of the present invention will be described in detail with reference to the drawings. The following embodiments are merely examples, and various modifications can be made without departing from the spirit of the present invention.
[0016]
[Outline of the system]
FIG. 2 is a functional schematic diagram of the multipoint observation system according to one embodiment of the present invention. In this system, the field computer FC organizes and collectively collects data for each instrument point while organizing the observation point type information such as “polygonal points”, “boundary points”, “projection points”, and “current points”. To observe. Observation data of each observation point obtained by observation is accompanied by observation point type information, and is transferred from the field computer FC to the host computer HC after the collective observation. After the transfer of the observation data, the host computer HC discriminates the acquired observation data on the basis of the observation point type information, and obtains a “polygonal notebook”, a “boundary notebook”, a “project notebook”, It is output in separate observation lists, such as "Status map".
[0017]
To explain the observation method more specifically, when observing using the total station, the polygonal points are “polygonal points”, the boundary points are “boundary points”, the protruding points are “protruding points”, and the current point is “current state”. Select the type of point you want to observe at one instrument point (auxiliary reference point, polygonal point, traversal point) like "point" and observe all points you want to observe from the instrument point at once .
[0018]
For example, a total station is installed at a certain reference point (for example, P11 (FIG. 1)), and this reference point is used as an instrument point. First, “polygonal point”, “boundary point”, “projection point”, and “current point” A half-pair observation is performed at the point indicated. When the first half-pair observation is completed, the telescope of the total station is turned over, and the remaining half-pair observations are performed only at the observation points designated as “polygonal points” and “projection points”, and a total of one pair of observations is performed. Observation of
[0019]
When the first pair of observations is completed, the process proceeds to the second pair of observations, in which only the points designated as “polygonal points” are observed. In this way, when all the points to be observed from the instrument point are observed at once and the observation from one instrument point is completed, the total station is moved to the next instrument point [for example, P12 (FIG. 1)]. And repeat the same observation work. Such collective observation work for each instrument point is sequentially performed, and all observation data from all planned instrument points [for example, P11 to P14, Q21 to PP24 (FIG. 1)] are acquired.
[0020]
Observation data by collective observation for each instrument point is accompanied by observation point type information corresponding to instructions such as "polygonal point", "boundary point", "projection point" and "current point", and is stored in the memory of the field computer FC. Recorded in. When all the observation work is completed, the operation returns to the office and transfers the observation data to the host computer HC. The observation data taken into the host computer HC is separated into different observation points based on the instrument point information and the observation point type information (“polygonal point”, “boundary point”, “projection point”, “current point”). It is output in a book.
[0021]
FIG. 2 shows an example of a system block diagram of a total station that can be used in the multipoint observation system according to one embodiment of the present invention. In this example, the total station TS (FC) includes a control unit including a central processing unit (CPU) 1, a main memory (RAM) 2, a read-only memory (ROM) 3, a static RAM (SRAM) 4, an IC card drive 5, and the like. An operation unit having front and rear keyboards 6 and 7, a display unit having front and rear displays (for example, LCD displays) 8 and 9, and an observation unit having distance measurement and angle measurement systems 10 and 11. And also has the function of the field computer FC of FIG.
[0022]
The CPU 1 controls each section of the system based on a total station control program stored in the ROM 3 to the IC card (set in the drive 5) together with the main memory 2 for storing data under calculation and the like. The CPU 1 also controls a guidance screen for setting an observation condition according to the observation point type. When the observation condition is set, the CPU 1 can monitor the progress of the observation according to the set observation condition. it can.
[0023]
The ROM 3 stores a program such as a calculation program necessary for functioning as a total station, and can be configured to be updatable using, for example, a flash ROM. The SRAM 3 is a memory for storing observation data obtained by total station observation, and the IC card drive 5 is provided to enable use of an attached program for adding various additional functions as needed by the IC card. It is.
[0024]
The front keyboard 6 and the front display 8 are arranged on the front side of the total station housing, and the opposite keyboard 7 and the opposite display 9 are arranged on the rear side of the total station housing. A predetermined key of each of the keyboards 6 and 7 uses a display screen to designate an observation point type indicating an observation point type such as “polygonal point”, “boundary point”, “projecting point”, or “current point”. , And an operation function for giving control instructions such as “recovery completed”, “YES”, “NO”, “end”, and “plane data transmission”. The displays (LCD displays) 8 and 9 display operation guide information according to the type of observation point, various data necessary for observation work, and the like, and do not match observation conditions set according to the type of observation point. When the progress status is reached (for example, when there is an observation omission at the end of the observation), an error is displayed to alert the operator. The front and rear keyboards 6 and 7 can be remotely operated by a remote controller (remote controller) 12.
[0025]
Further, the distance measuring system 10 measures a distance by emitting a transmitting light from a sight (not shown) and entering a receiving light, and the angle measuring system 11 measures a vertical angle and a horizontal angle of the sight. Having. Note that the total station further includes a tilt sensor control unit that corrects the angle horizontally if the total station body is set within the horizontal allowable range, and displays an error on the displays 8 and 9 when the total station main body is out of the horizontal allowable range. be able to.
[0026]
In a multi-point type observation operation described later, the operator turns the total station supported by a support device (not shown) in the vertical and horizontal directions to perform collimation with the sight, and operates the operation buttons and the like on the keyboards 6 and 7. The necessary observation data can be automatically created by the CPU 1 from the observation data only by performing the instruction operation. The obtained observation data and the like are stored in the SRAM 4 and displayed on the displays 8 and 9 as needed, and the necessary observation data and the like can be output to the host computer HC via the communication port. .
[0027]
[Types of observation points and observation conditions]
Here, the types of observation points are briefly described as follows:
(1) Polygonal points = also referred to as auxiliary reference points and traverser points: points that are obtained supplementarily from reference points determined by the GSI, and are also points for installing instruments (total stations).
(2) Boundary point = a point that constitutes a boundary line such as land (point between land and land).
(3) Projection point = When a point to be observed cannot be collimated with the instrument (total station) installed at a polygonal point, this is the point where the point was protruded supplementarily. Observe points that cannot be observed from points.
(4) Current point = This is a point for creating a current topographic plan view, and is a point for observing the shape and the like of structures such as telephone poles and guardrails.
[0028]
Regarding the observation conditions of each observation point, as described in the Public Survey Work Rules of the Ministry of Construction, when observing by public survey at the site, for example, the observation point is an auxiliary reference point (polygonal point). In the case of a boundary point, the observation method differs as shown in (a) and (b) of FIG. 4 (1), and it is necessary to output the notebook separately. Therefore, it is necessary to separately observe the polygonal points and the boundary points according to the respective observation methods. As already described, if the total stations are installed at the same reference point (polygonal point, traversal point) and the observation is performed separately from the observation point type, the work efficiency is extremely poor.
[0029]
In the observation method according to the present invention, as shown in FIG. 4 (2), observation conditions are set in advance, polygonal points and boundary points are collectively observed for each instrument point according to the observation conditions, and the observation result is obtained. Based on observation point type information such as polygon points and boundary points, the data can be divided into a multi-point notebook and a boundary point notebook and output. Here, a comparatively simple example of observation work will be given. For example, when a polygonal point and a boundary point are collectively observed at a certain instrument point, the observation operation is performed as in the following (1) to (4):
[0030]
(1) First pair observation (first half = polygonal point + boundary point; second half = polygonal point):
First, observation of polygon points and boundary points is started in the positive direction of the total station. In this case, by operating the switches on the keyboards 6 and 7, observation point type information “polygonal point” is added for polygonal points, and observation point type information “boundary point” is added for boundary points. When the total station normal direction observation is completed, the total station is reversed and the second observation is performed on the polygonal points. When one pair of observations of the polygonal point is completed by these observations, the operator is asked whether or not to perform one pair of accuracy calculations by pressing the “end of the pair” switch, so that the “YES” switch is operated. To calculate the accuracy, or press the "NO" switch to go through this calculation process.
[0031]
(2) Second pair observation (multiple points):
At the end of the second polygonal point observation (reverse direction), the total station is collimating the rear viewpoint, so the horizontal angle is set to, for example, 270 degrees, and the second pair [third (reverse direction) and Fourth (positive direction)].
[0032]
(3) When the second pair (third and fourth) observation of the polygon points is completed, press the “end” switch. The total station monitors the progress of the observation in accordance with the observation conditions set in accordance with the observation point type. If the observation is forgotten, the displays 8 and 9 indicate "There is unobserved data." An error message is displayed and the observation leak is reported to the operator. In this case, the observation work may be added only to the observation point specified by the error message. After that, the accuracy calculation for two pairs (or one pair) is performed, and the observation work is completed.
(4) When the "plane data transmission" switch is operated after the observation work is completed, the observation data is output to the host computer HC through the communication port. In the host computer HC, the observation data of the polygonal points are accompanied by the polygonal point type information “polygonal points”, and the observation data of the boundary points are appended with the boundary point type information “boundary points”. The books are sorted and recorded in a predetermined storage area.
[0034]
As in this example, for the observation points, classification is performed based on the observation point type information such as “polygonal point”, “boundary point”, “projection point”, and “current point”, so that the combined traversal automatic search is performed. Can be added with a polygonal point search function, and the advantage of smooth search can be obtained. In addition, a boundary point can be searched when winding a boundary point image.
[0035]
[General work flow]
FIGS. 5 to 7 show work flow charts in the multiple point type observation system according to one embodiment of the present invention. In this work flow, observation point type information such as “projection point” and “current point” is used in addition to “polygonal point” and “boundary point” in the above-described example, and observation from a plurality of instrument points is considered. ing.
[0036]
First, the user goes to the observation site as shown in step S1, and in the next step S2, the total station is set at a predetermined reference point [for example, point P11 (FIG. 1)], and observation is started using this as an instrument point. As for the polygonal point, as shown in step S3, the user designates "polygonal point" on the displays 8, 9 by operating predetermined keys on the keyboards 6, 7, and switches the observation method to "polygonal". As in 2), two pairs of multipoint observations are performed, and multipoint observation data obtained by observing each multipoint is accompanied by observation point type information corresponding to “polygon points”.
[0037]
Next, as for the boundary points, as in step S4, the user designates “boundary points” and switches the observation method to “boundary”. For all the boundary points that can be observed, for example, as shown in FIG. Observation point type information corresponding to the “boundary point” is added to the boundary point observation data obtained by performing half-pair observations and observing each boundary point. Here, in the observation of the boundary point, there may be a boundary point that cannot be seen (impossible to collimate) from the place where the total station is installed (instrument point).
[0038]
Therefore, in the next step S5, it is determined whether or not all the boundary points and the current state point have been collimated from the instrument point. When there is an instrument point that cannot be collimated, the process proceeds to step S6, and Set a projecting point at a place where you can see the point and the current point, designate "projecting point", observe this projecting point one pair of times, and observe the projecting point obtained by observing each projecting point. , The observation point type information corresponding to the “projection point” is added. When observing the protruding points, a total station is installed at all protruding points, and a "boundary point" is designated, and the observation work of the corresponding boundary points is sequentially performed. When all the boundary points and the current state points can be collimated, the process goes from step S5 to step S7 (FIG. 6) without setting the protruding point.
[0039]
Next, as in step S7, the observation method is switched to "current" by designating "current point", and for all current features, for example, as shown in FIG. Then, observation point type information corresponding to “current state point” is added to the current state observation data obtained by observing each current state point. Then, when the observation at all the observation points to be observed at the instrument point is completed, it is determined in step S8 whether or not the next instrument point exists. If there is still an instrument point to be observed, the process returns to step S2, and the operations of steps S2 to S7 are repeated. Then, the total station is installed at all the polygonal points and the projecting points, and when all the observation work of steps S2 to S7 is completed, the process proceeds from step S8 to step S9.
[0040]
In step S9, the process returns to the office and transfers all observation data to the host computer HC. In step S10, the observation data taken into the host computer HC is assigned to which observation data is assigned to which observation log based on the conditions set corresponding to the observation point type information added to each observation data. Is determined. After the process of distributing the observation data to each notebook in step S10, the notebook data and the current basic data are created in the next step S11. Based on the notebook data created here, a printing process is performed in steps S11a to S11c, and an observation notebook of polygonal points, boundary points, and projecting points can be printed.
[0041]
Thereafter, the process sequentially proceeds to steps S12 to S14 (FIG. 7) to perform traverse calculation. In step S12, a traverse calculation is performed to determine the coordinate values of the polygonal points. In the next step S13, a radial traverse calculation is performed to determine the coordinate values of the salient points. In step S14, a radial traverse calculation is performed to determine the boundary points. And the coordinate values of the current point are determined. Finally, in step S15, a current state plan view or the like is created by CAD or the like based on the determined coordinate values, and this work flow ends.
[0042]
【The invention's effect】
As described above, according to the present invention, observations are collectively observed for each instrument point while organizing the observation point type information, and the obtained observation data is discriminated into separate observation lists according to the observation point type information. It is not necessary to go to the same site many times for observation, and it is not necessary to set up the total station many times at the same instrument point. The time required for the work and the output of the observation notebook can be shortened, and effects such as being extremely efficient can be obtained.
