The present invention relates to an observation support system for supporting a reference point surveying operation using a positioning system (global positioning system), and a recording medium therefor.

[0002]

2. Description of the Related Art On-site observation work in GPS surveying is as follows.
To install a plurality of GPS antennas and receivers at a plurality of measurement points (given points whose coordinate values are already known and new points whose coordinate values are to be obtained), and receive radio waves transmitted from artificial satellites. . Before and after the GPS observation at such a site, observation planning work and result creation work are performed indoors using software.

[0003] For example, prior to on-site observation, information taking into account the movement of an artificial satellite is obtained, and as shown in FIG. 1, one observation (one session) performed in the same time period and a certain period of time. It is necessary to secure a time zone in which radio waves from four or more satellites can be received. In this case, the satellite arrangement state (PDOP) also needs to be dispersed to some extent. In Japan, many points are located in mountainous areas, and there are many obstacles (called "curtains") that block satellite radio waves around the stations, as shown in FIG. Therefore, before the on-site observation, it is necessary to investigate the shape of the obstacle and calculate the observable time zone satisfying the above conditions.

[0004] For the on-site observation work, in addition to the above-mentioned reception conditions, it is necessary to set a correct average chart in advance and to plan a session in consideration of the set average chart.
A limited number of GPs corresponding to the planned sessions
The S antenna and the receiver must be placed at the required measuring point at the required time.

[0005] Further, even after the on-site observation, the work of creating a result is performed using the data acquired by receiving the satellite radio wave.
For example, in the baseline analysis for calculating a three-dimensional vector, there is a unique calculation procedure that requires specialized knowledge, such as a session and a measurement point for starting the calculation and a rule for setting a start point and an end point for each vector.

[0006] Such an observation plan and result creation work before and after the GPS site observation is an indoor work using software. In order to carry out the above-mentioned work while satisfying various rules with commercially available general software, it takes a great deal of time for various inputs, settings, calculation times, and the like. Since efficient human resources (experts) are required, work cannot be carried out efficiently.

[0007]

For example, an existing drawing is pasted, and the existing coordinate values in the drawing are set by performing rotation or scale reduction in software, and coordinate values of other points in the drawing are calculated.

[Overview of Work Process] In general, the reference point surveying operation using GPS (GPS surveying) can be roughly classified into:
There are the following three items: (1) Observation planning work before observation, (2) Actual observation work on site, (3) Result creation work using observation data (various calculations, etc.).

In GPS surveying, the observation work performed on site is to install a plurality of GPS antennas and receivers at a plurality of measurement points and receive radio waves transmitted from artificial satellites. Here, the measuring point includes a given point whose coordinate value is already known and a new point whose coordinate value is to be obtained, and the number of GPS antennas and receivers that can be simultaneously arranged at each measuring point is basically Is determined by the number of observers. G like this
Since there are several rules for PS observation, it is necessary to confirm whether these rules are satisfied in the observation planning work before observation in (1). For example,
In the observation planning work of (1), it is necessary to pay attention to the following points.

In one session, as described above, radio waves transmitted from four or more satellites located at an elevation angle of 15 degrees or more can be received for a predetermined time, and the satellite arrangement state (PDOP) is changed. There is a condition that it must be dispersed to some extent. In addition, it is necessary to investigate the shape of the curtain (obstacle) in advance and calculate an observable time zone satisfying this condition.

Before on-site observation, it is necessary to establish a plurality of sessions according to the number of measurement points to be observed and the number of GPS antenna receivers that can be used simultaneously. In this case, at the time of inspection calculation for producing results after on-site observation, a three-dimensional vector (d
In consideration of obtaining the difference and the difference between (x, dy, dz), a session plan that satisfies a predetermined condition such as observing at least one side of each session overlapping with the side of another session is required. There must be. Further, it is desirable that an arrangement schedule of these GPS receivers be drafted in advance.

In the result creation stage, a three-dimensional net average calculation is performed using the three-dimensional vector group and the given point coordinates in order to obtain a new point coordinate which is the final result. In the figure, if there is a “missing” of a vector for which the three-dimensional network average cannot be calculated, inconvenience will occur in the calculation of the final result. It is necessary to keep.

After the on-site observation, the work of creating the result of (3) is performed using the data acquired by receiving the satellite radio wave.
Some rules also occur in each of these operations.
For example, in the baseline analysis for calculating a three-dimensional vector, the order of calculations such as which measurement point in which session should be started, or the start point / end point of each vector, and calculation of a certain vector or session There are unique rules such as sending calculation results such as passing results (coordinate values) to adjacent vectors and sessions and calculating.

According to one embodiment of the present invention, in the operation (1) described above, various kinds of plan information are automatically registered or generated based on the observation plan.
Not only the on-site observation work in (2), but also the work of creating results such as baseline analysis and three-dimensional net average calculation in (3) (baseline analysis, three-dimensional net average calculation, etc.), and automatic calculation of various work rules Can be realized.
FIG. 4 is a diagram showing main steps of the observation support system according to one embodiment of the present invention. The steps in this system are:
Large, observation plan stage ST1, on-site observation stage S
It can be divided into T2 and result creation stage ST3,
Each stage corresponds to each of the operations (1) to (3).

Referring briefly to FIG. 4, the observation system according to one embodiment of the present invention includes an observation plan stage S
At T1, curtain information is generated based on obstacle observation data, and curtain information and observation point information (DB1)
, Generating average map information (DB2) according to a predetermined rule based on the observation condition information, observation point information and average map information, according to a predetermined rule.
And generates GPS receiver deployment schedule information according to a predetermined rule based on the GPS receiver usage conditions and session plan information, and generates the schedule information (DB4).
To the GPS receiver. In the result creation stage ST3, various plan information (DB1 to DB4) and GPS
Baseline analysis calculation is performed according to a predetermined rule based on the receiver observation data (ST2).

In the first observation plan stage ST1, scheduled observation points (stations) are determined before on-site observation, and attribute data (point attributes) at each measurement point, average map data representing connections between points, and Session configuration data representing the configuration of a session, which is one observation range performed in a time zone, and receiver location data representing the location of a GPS receiver assigned to each measurement point for each session are created. Attribute database DB1 and average map database DB provided in different storage areas (or storage media)
2. Stored and registered in the session database DB3 and the receiver arrangement database DB4.

In the next on-site observation stage ST2,
By referring to various data registered in these databases DB1, DB3, and DB4, actual observation work is sequentially performed according to a work plan indicated by the information content. Then, the result creation work is started in the result creation stage ST3, and the observation data acquired in the stage ST2 is processed and various calculations are performed while referring to the session-related data registered in the databases DB1 to DB3.

FIGS. 5 and 6 are functional block diagrams showing schematic functions of the observation support system according to one embodiment of the present invention. As described above, the on-site observation work in the GPS survey consists in installing a plurality of GPS antennas and receivers at a plurality of measurement points and receiving radio waves transmitted from artificial satellites. Here, the measuring point includes a given point whose coordinate value is already known and a new point whose coordinate value is to be obtained, and the number of GPS antennas and receivers that can be simultaneously arranged at each measuring point is basically Is determined by the number of observers. As described above, since there are several rules for GPS observation, it is necessary to confirm whether these rules are satisfied in the observation planning stage before observation.

Therefore, in the observation planning stage ST1, the host computer 1 is first used to execute a scheduled GPS observation as shown in a functional block B1.
Set observation conditions such as the number of the receiver owned by the observer and the scheduled date and time of observation. In addition, as shown in a functional block B2, the coordinate data (point data) of the planned measurement point is read by a method such as reading data of a point planned as a measurement point for GPS observation using the tablet 12 or the like. Generate. The printer 13 can print out a “coordinate conversion calculation” using the point data. The coordinate conversion calculation includes, for example, a coordinate system (Vessel) unique to Japan.
And a coordinate value converted between a coordinate system (WGS84) common to the world.

The coordinate data (point data) of these scheduled points
Is added with a point attribute including an eccentric attribute in a functional block B3, and is registered in the point attribute database DB1 of the external storage device 4. Here, the point attribute is an attribute when performing various calculations, for example, “base station” for performing baseline analysis, “BLH fixed”, “known point”, “new point” for performing assumed network calculation. , "Node" and "eccentric point" for performing eccentricity calculation.

As described above, 1 performed in the same time zone
In one observation (one session), radio waves from four or more satellites can be received for a certain period of time in consideration of the movement of artificial satellites, and the satellite arrangement (PDOP) is dispersed to some extent. It is necessary to secure the time zone in which it is. In addition, in Japan, many points are located in mountainous areas, and there are many curtains around the measuring point that block satellite radio waves. It is necessary to calculate a suitable time zone. If the observable time zone cannot be calculated from the curtain information, eccentric observation and eccentricity calculation are required.

For this reason, before the on-site observation, in order to generate curtain (obstacle shape) information and to calculate eccentricity, the total station 10 is used to set the horizontal angle and the altitude angle (over 360 degrees) of each scheduled measurement point. Obstacle data) and TS observation data on the horizontal angle and altitude angle (TS eccentricity observation data) between two measurement points are acquired. Alternatively, for generating curtain information, the digital camera 11 is used to acquire sky image data of a 360-degree field of view at each measurement point. In this case, it is preferable to use a digital camera using a fish-eye lens that can capture a 360-degree sky image at a time as the digital camera 11. In the functional block B4, the curtain information is automatically generated from the TS observation data or the image data acquired before the observation, and registered in the curtain information storage area of the external storage device 4. The "curtain information" can be printed out from the printer 13.

After the GPS site observation, in order to obtain a new point coordinate as a final result, when performing a three-dimensional network average calculation using the three-dimensional vector group and the given point coordinates, the three-dimensional vector group is expressed. If the “average diagram” includes “missing” of a vector for which the three-dimensional network average cannot be calculated, inconvenience occurs in calculating the final result. Therefore, it is necessary to prepare an average map without such omissions before the on-site observation, and to make a session plan based on the average map. When making a session plan, a three-dimensional vector (dx,
Since it is necessary to take into account the calculation of the difference and the difference between the dy, dz), correct session settings must be set so that at least one side of each session can be observed overlapping with the other session. Plan ahead.

In the function block B5, such average map data and session plan information are transferred to the function blocks B1 to B5.
It is automatically generated based on the observation condition data, point data, point attribute data, and curtain information obtained in B4, and is stored and registered in the average map database DB2 and the session database DB3 of the external storage device 4. The session plan information generated here includes a session shape, a detailed scheduled observation date and time, and is sent from the printer 13 to various session plan graphs in a graph format (for example, “number of satellites and PDO”).
P "," elevation angle "," azimuth "," number of satellites "," satellite ",
"Skyplot", "PDOP", "HDOP",
“VDOP”, “GDOP”, “TDOP”, etc.).

As a consideration before the GPS in-situ observation, depending on the number of measurement points to be observed and the number of GPS receivers that can be used at the same time, it is necessary to form a plurality of sessions,
It is necessary to plan the arrangement schedule of the S antenna receiver in advance. Therefore, in the function block B6, G
Based on observation conditions such as a PS receiver number and session plan information, schedule information indicating an arrangement schedule of the GPS receiver is automatically generated, and stored and registered in the receiver database DB4 of the external storage device 4. The schedule information reflects the contents of the point attribute / session [DB1, DB3], and the printer 13 can print out a "schedule table" or the like based on the schedule information.

In the next on-site observation stage ST2,
The schedule information [DB obtained in the function block B6
4] is automatically registered in the GPS device 9, the GPS device 9 is arranged and operated in accordance with the registered schedule information,
At each station, observation data is acquired by receiving satellite radio waves (type of radio waves from artificial satellites = L1 band, L2 band).

After the site observation, the result creation stage ST
In step 3, various operations for creating results are performed using observation data acquired by receiving satellite radio waves. Some rules also occur in each of these operations. For example, in the baseline analysis for calculating a three-dimensional vector, the order of calculation such as what measurement point in which session should be started, or what the start point / end point should be in each vector, and calculation of a certain vector or session There are unique rules such as sending calculation results such as passing results (coordinate values) to adjacent vectors and sessions and calculating.

For this reason, in the result creation stage ST3,
In addition to handing over the information registered and generated based on the observation plan to the on-site observation work, as shown in functional blocks B7 to B10, results creation work such as baseline analysis and three-dimensional net average calculation (baseline analysis, three-dimensional Network average calculation, etc.)
A mechanism for automatically calculating various work rules is also realized.

That is, in the function block B7,
Observation data from the GPS device 9, point attribute data [DB1] from the function block B3, average map data and session information (session plan information) from the function block B5
Baseline analysis calculation is automatically performed based on [DB2, DB3]. From the printer 13, the observation data and the baseline analysis results (coordinates) describing the observed raw information [point number (No), antenna height, observed satellite status, etc.) are obtained from the observation data and the baseline analysis results. Various drawings can be printed out in addition to the “observation book” in which values, vectors, etc. are described.

In the function block B8, the function block B7
Inspection calculation is automatically performed based on the baseline analysis result obtained in step (1), and an “inspection calculation book” is output from the printer 13 by the inspection calculation. In the function block B9, the results of the baseline analysis and the point attributes from the function blocks B7 and B2,
In addition, an eccentricity calculation is performed based on the TS eccentricity observation data regarding the horizontal angle and the altitude angle between the two measurement points obtained by the eccentricity observation of the total station 10, and the eccentricity calculation book and the eccentricity calculation book are printed by the printer. 13 is output.

In the function block B10, the function block B
The three-dimensional network average calculation is performed based on the base line analysis results and the point attributes from 7 and B2, and further, the functional block B11 performs the quality management calculation based on the result of the three-dimensional network average calculation. By the three-dimensional network average calculation and the quality control calculation in the functional blocks 10 and B11, the "three-dimensional network average calculation report", "result table", "quality control table", and "quality control calculation book" are respectively sent from the printer 13. Is output.

In the following step M 3, curtain information automatically generated from TS observation data or image data from the total station 10 or the digital camera 11 is registered in the curtain information storage area of the external storage device 4.
Also, in step M4, a session plan is executed according to a predetermined rule, and average map data is created based on the arrangement state and point attributes of the points to be observed. In consideration of this, the shape and observation date and time of all sessions are calculated, and session plan information is automatically created.

After the creation of the average chart data and the session plan information in step M4, a schedule creation operation is performed in step M5. In this schedule creation work, how to arrange the limited number of GPS receivers (GPS devices 9) is determined in accordance with the shape of the session, and automatic setting is performed for each receiver. Observation information is set. By this operation, schedule information for instructing the arrangement and operation of the GPS receiver (GPS device 9) is automatically created.

Next, in the on-site observation stage ST2 (outdoor work), in step M6, schedule information is automatically registered in the GPS device 9, and the GPS device 9 is arranged at each measurement point according to the registered schedule information. Perform GPS in-situ observations. In this case, it is determined in step M7 whether or not eccentric observation is necessary. If it is determined that eccentric observation is necessary, eccentric observation by the total station (TS) 10 is performed in step M8. In this eccentric observation, a place where it is impossible to acquire radio waves from the satellite is referred to as an “eccentric point”, and a temporary measurement point is set as an “eccentric point” in the vicinity, and GPS observation is performed at this eccentric point Do. In this case, TS

There are a hypothetical net average calculation in which values are fixed and a practical net average calculation in which all given points are fixed and calculated. further,
In step M13, an accuracy management calculation for verifying the accuracy of the given point is performed using the existing coordinate values of each given point and the result calculated by the three-dimensional net average calculation.

Here, if a good result is not obtained in each of the processes in steps M10 to M13 (NG), the process returns to step M10 and the processes in steps M10 to M13 are executed again. If a good result is not obtained, it is also possible to return to step M12 and start over from the three-dimensional network average calculation. If a good result is not obtained in each of the processes of Steps M10 to M13 (NG), the process may return to Step M3 of the observation planning stage ST1 and start over from the planning stage as necessary.

(1) Curtain Information Registration System A “curtain” is an obstacle that exists between an artificial satellite and a GPS antenna and blocks radio waves transmitted from the satellite, and is mainly used for structures such as buildings and the like. For example, forests. G
In PS surveying, confirm the location of the curtain in advance,
Observation must be made in consideration of the time zone during which satellite radio waves are not cut off. However, at present, it is necessary to manually input the curtain shape (azimuth angle, altitude angle) observed at the total station or the like. Therefore, when observing the same point at another time, input the curtain shape again or use the previous curtain. If the shape does not remain, it is necessary to go to the site and observe again using the total station. Therefore, there is a problem that such a method by manual input is inefficient and that the curtain information once registered cannot be separately reused for another work.

In one embodiment of the present invention, by constructing a system for automatically registering curtain information, G
In the PS observation planning stage, the curtain information can be efficiently created, and the created curtain information can be reused. FIG. 9 is a functional block diagram showing a schematic function at the stage of curtain information registration according to one embodiment of the present invention, and mainly shows the function of the functional block B4 in the functional block diagrams of the entire system shown in FIGS. Corresponding.

In short, referring to FIG. 9, in the curtain information registration system according to one embodiment of the present invention, the APA survey data from the file or the total station 10 or the sky image data from the digital camera 11 or the bitmap file Are acquired as obstacle observation data (CB1, CB2, CB4), and curtain information of the observation scheduled point is automatically generated based on the acquired obstacle observation data. In the case of APA survey data, each observation point of the direction angle and the altitude angle is automatically developed on the curtain registration screen as a shape change point of each curtain. In the case of sky image data, it is displayed on the curtain registration screen,
The curtain information is registered by pick input with the image data as a background.

In one embodiment of the present invention, the horizontal angle and the altitude angle of a predetermined point are obtained by surveying, and the already-observed data (the surveying data in the APA format) in a format common to each user is transmitted to the communication interface (shown in FIG. ), And is stored and registered in a file provided in a predetermined area (medium) of the external storage device 4 of the host computer 1 in advance. When the survey data of the scheduled observation point (measurement point) is registered in this file, the already-observed data of the planned point is directly read from this file as shown in a function block CB1.

Alternatively, TS observation data (APA format) relating to the horizontal angle and the altitude angle of the observation point is acquired by the total station 10 and, as shown in the function block CB2, the T
S observation data is directly received and taken into the system.

The previously-observed data or the TS observation data in the predetermined format (APA format) obtained in the functional blocks CB1 and CB2 are used in the functional block CB3.
Observation point of the already observed data or total station 10
By setting the installation point as a GPS observation point (measurement point) and developing each observation point as a shape change point of each curtain, it is automatically developed as a curtain shape. Therefore, since the curtain information is generated only by the operator reading the APA data, the curtain information creation operation can be performed very efficiently. Note that the function block CB3 can be edited as needed. In addition, even when the same point is separately observed, the data in the APA format can be reused.

In one embodiment of the present invention, a curtain registration function on image data can be provided in addition to using already observed data or TS observation data in APA format. For example, a digital camera 1 with a fisheye lens
For each observation point (measurement point), 36
Sky image data in a bitmap format (for example, BMP) extending over 0 degrees is acquired, and a curtain shape can be created using this image data. In this case, in the functional block CB4, the digital photographing data of the sky image is fetched from the digital camera 11 or the bitmap file and displayed on the curtain registration screen of the display 6.

Next, as in the functional blocks CB5 to CB7, the image scale is changed and the azimuth (angle) is changed as necessary.
Is changed or the image is inverted vertically and horizontally. That is, since the image data is image data captured by a fisheye lens, various operations can be performed on the image. For example, in order to finely adjust a correct direction, rotation of an azimuth axis with respect to the image is possible. In order to replace the line of sight with a correct line of sight, it is also possible to flip the image vertically and horizontally.

After performing the required image operations as described above,
As in the function block CB8, on the image data,
By picking a curtain (obstacle) with image data as a background without being aware of the direction angle or altitude angle, curtain information in a bitmap format is created and stored / registered in a predetermined storage area of the external storage device 4. can do. Further, by storing the curtain information in the bitmap format, it becomes possible to immediately cope with a case where it is necessary to separately observe the same point.

FIGS. 10 to 14 are flowcharts showing the curtain information registration processing executed in the curtain information registration system according to one embodiment of the present invention. In this curtain information registration process, in the first step C1, "A
"PA" registration, "Editor" registration or "Image" (BMP)
The process is started by selecting one of the registration methods from the registration, and a curtain information registration screen is displayed on the display 6. Here, if "editor" registration (editor) is selected in step C1, step C2
To "C4" registration processing is executed, and "APA"
If registration (APA) is selected, steps C11 to C20
"APA" registration processing (FIG. 11) is executed, and "image"
If (BMP) registration is selected, steps C31 to C48
Is performed (FIG. 12 and FIG. 13).

["Editor" registration processing] For the previously observed data or TS observation data in the APA format,
If "editor" registration is selected in step C1, curtain information registration work is performed on the editor using, for example, a curtain registration program of Trimble (Trimble). For example, while viewing the output paper of the TS observation data, Azimuth and elevation can be manually entered. That is,
When the station number is selected in step C2 and the editor is started in step C3, in step C4 curtain information relating to the station of the registered number is entered in accordance with a predetermined editor program (for example, the above-described trimble program). It is created and stored / registered in a predetermined storage area of the external storage device 4.

Then, in step C5, it is determined whether or not curtain information is registered for another station number data or another kind of observation data, and curtain information is registered for another station number data or another kind of data. If (YES), the process returns to step C2 or step C1, and if another data is not registered (NO),
This curtain information registration processing ends.

["APA" registration process] When "APA" registration is selected in step C1 for the already-observed data or TS observation data in the APA format, the station number is selected in step C11 (FIG. 11). In step C12, a method of acquiring observation data is determined. Here, in the case of already-observed data, the process proceeds to step C13,
The external storage device 4 is driven to select an observation data file. If the observation data file is stored in the total station 10, the process proceeds to step C14 to perform communication setting (RS232C) with the total station 10. In the following step C15, predetermined observation data registered in the file or new observation data from the total station 10 is loaded into the system, and the read observation data is displayed on the curtain registration screen of the display 6. Curtain information is generated by automatically developing the curtain shape using the next observation data measurement point as the curtain shape change point.

Next, in step C16, step C
In step C17, it is determined whether or not to edit the curtain shape obtained in step 15, and if so, the editing mode is determined. In the case of single editing, single editing is performed in step C18. In the case of continuous editing, after performing continuous editing in step C19, the process proceeds to step C20.
If it is determined in step C16 that the curtain shape is not edited, the process immediately proceeds to step C20.

In step C20, curtain information representing the curtain shape of the measurement point is stored and registered in a predetermined storage area of the external storage device 4. In the next step C21 (FIG. 10), another number or another type of data is stored. It is determined whether or not (curtain information) is to be registered. If another number or another type of data is to be registered (YES), step C2 is performed.
Returning to step 1 or step C1, if another data is not to be registered (NO), the curtain information registration processing is terminated.

[“Image” Registration Process] Digital Camera 11
When the sky image data of 360 degrees from is read and the “image” registration is selected in step C1, the station number is selected in step C31 (FIG. 12), and in the next step C32, of the read image data, The corresponding image data is selected and displayed on the curtain registration screen of the display 6. In the next step C33, it is determined whether or not the image data has a scale. If there is a scale, the image data is converted to a standard scale in step C34. If not, the current scale is maintained (step C35). In a succeeding step C36, it is determined whether or not the azimuth axis (angle) is changed in the image data. If there is a change in the azimuth axis (angle), the image data is converted into a standard azimuth axis (angle) in step C37. If not, the current azimuth axis (angle) is maintained (step C
38).

Further, in step C39, it is determined whether or not the image data is vertically inverted. If the image data is vertically inverted, the image data is converted to the standard state in step C40. If not, the current state is maintained (step C39). C41). Subsequently, in step C42 (FIG. 13), it is determined whether or not the image data has left / right inversion. If there is left / right inversion, the image data is converted to the standard state in step C43. If not, the current state is maintained. (Step C44).

As described above, when the image data is reset to the standard state, the editing mode of the image data is selected in step C45. In the case of the continuous mode, the continuous mode editing is performed in step C46. Is Step C4
In step 7, single mode editing is performed. In the editing operation in any of steps C46 and C47, curtain information in a bitmap format can be created by picking and inputting a curtain (obstacle) with the image data as a background.
Then, in step C48, the created curtain information is stored and registered in a predetermined storage area of the external storage device 4.

In the next step C49 (FIG. 10),
It is determined whether or not to register another number or another type of data (curtain information). If another number or another type of data is to be registered (YES), the process returns to step C31 or step C1 to register another data. If not (NO), the curtain information registration process ends.

FIG. 15 shows an example of a curtain information registration screen displayed on the display 6 at the time of curtain information registration processing. FIG. 15A shows the registration of an observation data file and APA observation data from the total station 10 in “APA”. FIG. 15B shows an example in which image data from the digital camera 11 is registered as an “image”.

(2) Session Planning System Before the observation of the GPS survey, as described above, an average map is prepared, and a plurality of sessions are performed according to the number of observation points to be observed and the number of GPS receivers. Or cross,
It is necessary to observe one or more sides of each session so as to overlap with the sides of other sessions. In one embodiment of the present invention, an average map automatic creation function for automatically creating an average map in consideration of the arrangement information of given points and new points, all conditions and date and time are taken into account in consideration of various conditions and existing information. A session plan creation system with various functions, such as a session automatic creation function that automatically calculates all data in a batch, and a public survey work regulation check function that easily checks whether each piece of information created in an observation plan meets each standard of the work regulation. Can be built.

FIG. 15 is a functional block diagram showing a schematic function in a session plan creation stage according to one embodiment of the present invention. Mainly, a functional block B5 in the functional block diagram of the whole system shown in FIGS. Corresponding to the function of. In this example, the session plan creation system includes an average chart creation processing unit (SB1, SB2), a session creation processing unit (SB3 to SB5), and a work rule restriction check processing unit (SB6). Briefly referring to FIG. 15, the session plan creation system according to one embodiment of the present invention is based on the coordinate information and the attribute information of the observation point.
According to a predetermined rule, average map information is generated in consideration of the arrangement information of a given point and a new point (SB1). Next, based on the observation condition information, the coordinate information and the attribute information of the observation point, and the generated average map information, the shape and observation time (date and time) of the session in consideration of various conditions and existing information are represented according to a predetermined rule. The session plan information is generated (SB3). Also, the generated session plan information
It is checked whether or not a predetermined check criterion according to the survey work rules is satisfied (SB6).

In the average map creation processing section, an average map is automatically created in the function block SB1 based on point coordinates and point attributes in consideration of arrangement information of given points and new points. The created average map is edited by the function block SB2 as necessary, and can be made a more efficient average map.

In the session creation processing unit, in the function block SB3, the shapes and the dates and times of all sessions are automatically and collectively taken into consideration in consideration of various conditions such as point coordinates, point attributes, average maps, curtain information and existing information. Created. The shape and date and time of the created session are edited as necessary in the function blocks SB4 and SB5, respectively, so that an optimal session can be obtained.

In a function block SB6 comprising a work rule limit check processing section, an average map prepared in an observation plan,
It checks whether the session information, etc., meets the various standards defined in the work rules. Note that this check function is a simple standard function, and in actuality, it is necessary to specifically adjust it in principle according to the contents of observation.

[Average Chart Creation Processing] FIG. 16 is a flowchart showing an average chart creation processing executed in the session plan creation system according to one embodiment of the present invention. When the average chart creation processing flow is started by operating the operator of the input operation device 5, in a first step S1, it is checked whether or not a measurement point is set. The process proceeds to S2, and if not, the average map creation process is canceled in step S3 and the process ends. In step S2, it is determined whether or not to automatically create an average chart.
Otherwise, the process proceeds to step S5 to create a manual.

As is well known, the coordinate value of the new point, which is the final result of the GPS survey, is obtained by the 3
It can be obtained by performing an average calculation (three-dimensional net average calculation) using the coordinate values of the dimensional vector group and the given point. In this case, the three-dimensional vector group and the average diagram representing the connection need to be determined before observation and approved by the observing ordering organization. However, not only is it necessary for an expert to consider each point arrangement, but it is extremely inefficient.

For example, four points A, indicated by ●,
When two new points C and D represented by B, E, F and ○ are set and the connection between the measurement points A to F is configured as shown in the average diagram of FIG. The average chart is appropriate without any inconvenience, but in the average chart of FIG.
There is an omission (dashed line) in the connection of the three-dimensional vector group between D, and the setting is such that a vector cannot be generated. When an observation is performed based on an erroneous average map as shown in FIG. 17 (2), a base line connecting the new points C and D cannot be obtained. Is required.

In one embodiment of the present invention, when the process proceeds to step S4, the existing average information such as the arrangement information of the given point and the new point (measurement point) is considered, and the average map automatic creation processing program executes
An average map automatic creation process is executed according to a predetermined rule set in advance. Here, existing information used for automatic creation of an average map includes plane coordinates of a given point and a new point, a point attribute at the time of baseline analysis, a point attribute at the time of eccentric observation, a point attribute at the time of calculating a net average, and the like. Rules for creating a diagram include (1) connect from a point having a short distance, (2) do not connect when crossing, (3) do not connect between given points, and so on.

Therefore, in step S4, according to the average diagram creation rules (1) to (3) and the like, FIG.
An appropriate average chart as in (1) is automatically created. FIG.
8 shows an example of an average map automatic creation screen displayed on the display 6.

On the other hand, if the process has proceeded to step S5, the starting point number is selected in step S5, the ending point number is selected in the next step S6, and one base line in the average diagram is determined. Create manually.

When the average chart is automatically created in step S4, it is determined whether or not to edit the average chart in the next step S7. If the average chart is edited, the process proceeds to step S8 to start the editing work. Proceeds to step S9. Also,
Also in the case of manual creation, in step S6, 1
The process proceeds to step S8 each time the baseline is determined.

In step S8, it is determined whether or not to add a base line. If a base line is to be added, steps S5 and S6
And the base line is sequentially determined by selecting the start and end point numbers. If it is determined not to add a baseline, it is further determined in step S10 whether or not the baseline is to be deleted. To delete the baseline, a predetermined baseline is deleted in step S11, and the process proceeds to step S9. If not, go directly to step S9 from step S10.

At step S9, it is asked whether to save the created average map data. If so, the average map data is stored in a predetermined storage area (or recording medium) of the external storage device 4 at step S12. After the storage, the average map creation process is terminated. If the average chart data is not stored (discarded), the cancel processing is performed in step S3, and then the average chart creation processing ends.

[Session Creation Processing] FIGS. 19 to 23
5 is a flowchart showing a session creation process executed in the session plan creation system according to one embodiment of the present invention. First step S of this processing flow
At 21, it is checked whether or not a measurement point has been set. If a measurement point has been set, the process proceeds to step S22. If not, the session creation process is canceled at step S23 (FIG. 20) and the process ends. . In step S22, it is determined whether or not a session is to be automatically created.
4 to S30 (FIGS. 19 and 20); otherwise, the process proceeds to step S31 (FIG. 21) to create a manual.

In step S24, it is determined whether or not there is a given point.
If there is a given point, the presence or absence of an average map is determined in the next step S25. If there is an average map, the process proceeds to step S26, where a search point number is selected, and in step S27, a session automatic creation process is executed. Step S24,
If there is no point or average chart in S25, the process returns to step S22 to determine again whether to automatically create a session.

The shape of the session plays an important role in checking its observations and performing three-dimensional net average calculation.
(1) All connections (baseline) in the session always include all connections (baseline) in the average diagram. (2) Each session must be
It must be created according to basic shape rules such as making the baseline overlap with another session and making it adjacent.

For example, it is conceivable to set a session as shown in FIG. 24 corresponding to each of the average diagrams shown in FIG. 17, but in the session setting as shown in FIG. Since no interim observation occurs, no vector can be generated. Therefore, it is necessary to draft a correct session setting as shown in FIG.

In addition, the average shape shown in FIG. 25 (0) is compared with the session shape 1 shown in FIG.
Does not include the connection (base line) CD of the average diagram. Therefore, when the observation is performed in the session shape 1, since no observation occurs at the base line connecting the new points C and D, no vector is generated, which causes inconvenience to the three-dimensional network average calculation.
Also, in the session shape 2 shown in FIG.
The session Sa (dotted line), the second session Sb (double line), and the third session Sc (dotted line) include the connection (base line) of the average diagram, but the three sessions Sa to
Since all Sc do not have a baseline that overlaps with other sessions, check calculations cannot be performed.

As for the condition of the basic rule (2) adjacent to another session (baseline overlap), it is necessary to perform a check calculation such as a one-round error check and an overlap baseline difference check when checking the accuracy of observation data. Therefore, it is necessary to observe each session so that the baseline of the other session is always overlapped and adjacent.

In the check for calculating the result, in the one-round difference check, when the base line of the outer periphery of the session is closed and the circuit is made one round, each axis value dx, dy,
It is checked that the total value (difference in difference) of dz is equal to or less than a predetermined allowable value, and when closing the outer periphery, the overlapping portion with another session uses the baseline of another session. Also,
In the overlap baseline difference check, each axis difference dx, dy, d of each point observation data between baselines overlapping with another session.
It is checked that z is below a predetermined tolerance. Therefore, between adjacent sessions, as shown by the double line in FIG. 26, it is necessary to plan a session shape such that the sides are observed with overlapping.

Next, the date and time of the session also has a great effect on various results. As described above, in the case of GPS surveying, it is necessary to acquire radio waves transmitted from satellites (four satellites or more) having an elevation angle of 15 degrees or more for a certain period of time. In addition, the satellite constellation state (PDOP) at that time also needs to be dispersed.
For this reason, usually, the optimum observation date and time is determined in consideration of each condition for each session. In addition, since indexing is performed for each session, adjustments must be manually performed according to whether the date and time of another session do not overlap, etc.
It takes a lot of work time including various checks.

In one embodiment of the present invention, step S27
In, the session automatic creation processing program,
Various conditions such as scheduled observation date and time (scheduled start and end date and time), observation time, minimum number of satellites, minimum elevation angle, PDOP, number of receivers, etc., plane coordinates, attributes for baseline analysis, attributes for eccentric observation, Considering the existing information such as the attribute at the time of calculating the network average and the average map base line, according to the preset rules,
The shape and the date and time of all sessions are automatically calculated in a lump and a session is automatically created.

The rules for creating a session are (1)
Connect the baseline of the average map, (2) connect from a point with a short distance, (3) do not connect when crossing, (4) determine the session shape by the number of receivers from the existing selection point (for example, (5) In the next session, the session where the overlapping baseline exists is determined, and this is repeated. (6) After the shape is determined, the time zones satisfying various conditions are determined in session units. And so on.

Therefore, in step S27, according to the session creation rules (1) to (6) and the like,
Session plan data having an appropriate shape and an optimal date and time as shown in FIG. 24 (1) and FIG. 26 is automatically created. FIG. 27 shows an example of a session automatic creation screen displayed on the display 6. By such a session automatic creation process, the session is automatically calculated only by the user selecting a measurement point (point) of the start session, and the creation of session plan data can be advanced in a short time without an expert. Become. Also, there is no missing check.

When the session plan data is automatically created in step S27, it is determined in the next step S28 (FIG. 20) whether or not to edit the session plan data. If so, the process proceeds to step S31 (FIG. 21). Proceed to editing work, otherwise proceed to step S29. If the process proceeds to step S29, it is asked whether to save the created session plan data. If so, the session plan data is stored in a predetermined storage area (or recording medium) of the external storage device 4 in step S30. After that, the session creation processing ends. If the session plan data is not to be saved (discarded), the session process is terminated after canceling in step S23.

If it is determined in step S22 (FIG. 19) that the session is to be manually created, and if it is determined in step S28 (FIG. 20) that the session plan data is to be edited, the process proceeds to step S31 (FIG. 21). Press to enter manual editing / editing. First, step S3
In step 1, it is determined whether a new session is created or an already created (existing) session is edited. If a new session is created, the process jumps to step S32, and if an existing session is edited, the process proceeds to step S33.

When a session is selected in step S33, it is determined in the next step S34 whether or not the session is to be deleted. To delete the session, the session is deleted in step S35, and the process proceeds to step S36. The process proceeds directly from step S34 to step S36. In step S36, the session is displayed on the display 6.
It is determined whether or not to display the details in the upper part. If the details are to be displayed, the detailed display processing is performed in step S37, and the process proceeds to step S38.
Proceed to 8. In step S38, session editing is performed, and if the editing result is good, step S29 (FIG. 20)
Otherwise, discard the session and manually create a new session in step S32
Proceed to.

Steps S32 and S39 to S53 are processing steps for manually creating a new session. First, it is determined in step S32 whether or not various conditions are to be changed. If the conditions are to be changed, step S3 is performed.
In step 9, the conditions are changed and the process proceeds to step S40. Otherwise, the process immediately proceeds to step S40. In step S40, it is determined whether or not to change the constituent point (measurement points constituting the session). If the constituent point is to be changed, step S41 is performed.
And the process proceeds to step S42. Otherwise, the process immediately proceeds to step S42. In step S42, it is determined whether or not to change the configuration baseline (baseline constituting the session). If the baseline is to be changed, the baseline is changed in step S43 and the process proceeds to step S44. If not, the process immediately proceeds to step S44. move on

In step S44, it is determined whether or not to recalculate the observation-good time. If this time is to be recalculated, the observation-good time is recalculated in step S45, and the process proceeds to step S46. Immediately follows step S46
Proceed to. In step S46, it is determined whether or not the observation time is to be determined. If the observation time is to be determined, the observation time is input in step S47. After confirming the input, the flow proceeds to step S48. Otherwise, the flow immediately proceeds to step S48. In step S48, it is determined whether or not to confirm the edited session.
After the confirmation processing of the session is performed in step S50
(FIG. 23), otherwise immediately go to step S
Go to 50.

In step S50, the time of good observation is recalculated for all sessions, and it is determined whether or not processing for distributing all sessions to good time of observation is performed.
When these processes are performed, a date and time search is set in step S51 to recalculate the observation good time of all sessions and to distribute all sessions to the observation good time.
When it is determined in step S50 that such processing is not performed, and after the recalculation and distribution processing in step S51, it is determined in step S52 whether or not the names of the sessions are rearranged. Step S when rearranging
After sorting the session names in 53, step S2
Go to step S9, otherwise go to step S29 immediately.

In step S29, it is asked whether to save the session plan data manually created in steps S32 and S39 to S53, and if so, the session plan data is externally stored in step S30. Predetermined storage area (or recording medium) of device 4
After that, the session creation processing ends. If the data is not to be saved (discarded), the session creation processing is terminated after the cancellation processing in step S23.

[Work Rule Restriction Check Processing] In public surveying, a large number of standards are set for each work. Unless the work rules are well understood, various restriction conditions resulting from the work rules cannot be understood. It is not possible to correctly judge whether observations can be made as they are according to the observation plan. In other words, in the normal observation planning method, there is no mechanism to consider each standard of the work rules, so the user needs to perform a restriction check on each work process of the observation plan to see if various restriction conditions have been cleared. However, such a check requires a great deal of expertise and a great deal of time.

In one embodiment of the present invention, it is checked whether each information prepared in the observation plan satisfies each standard of the work rules. However, the checking function according to the following embodiment is merely a simple checking function. For more strict checking, it is preferable, in principle, to coordinate with a public surveying ordering organization, and it is necessary.

FIG. 28 is a flowchart showing a work rule restriction check process executed in the session plan creation system according to one embodiment of the present invention. When this processing flow starts, for example, the input screen on the display 6 is displayed, and the survey type is selected in the first step S61 using the input operation device 5, and the check item is selected in the next step S62. In this survey type, for example,
There are "1st grade control point survey"-"4th grade control point survey", etc.
Each class has different limits. Check items include, for example, “number of known points”, “distance between known points”, “distance between new points”, “number of routes”, “route length”, “distance between nodes”,
"Eccentric distance", "Azimuth distance", "Number of sides of unit polygon", "Route figure", "Number of satellites", "Minimum observation time",
There are "data acquisition interval", "elevation angle", "duplicate session", and the like. FIG. 29 shows an example of a work rule restriction check screen displayed on the display 6 during the work rule restriction check process.

In the next step S63, a check calculation is executed for the input check items according to the check rules according to the restriction conditions of the work rules corresponding to the survey type. For example, a check rule corresponding to the above-described check item is as follows: (1) “known points” = check the total number of given points,
(2) “Distance between known points” = check the distance between given points with the baseline using the average map, (3) “Distance between new points” = check the distance between new points with the baseline using the average map, (4) "Number of routes"
= Check the number of routes (shortest sides) between known points on the baseline using the average map. (5) "Route length" = Check the route length (shortest sides) between known points on the baseline using the average map. , (6)
"Inter-node distance" = check the node distance with the baseline using the average map; (7) "eccentric distance" = check the distance between the eccentric point and the azimuth mark with the attribute of the point; (8) "azimuth mark distance""=
Check the distance between the eccentric point and the azimuth mark in the point attribute,
(9) “number of sides of unit polygon” = check the number of outermost sides connecting points using the average map. (10) “route figure” =
Check the new point position at the outermost periphery connecting the points using the average map, (11) "Number of satellites" = Check the number of satellites entered under conditions, (12) "Minimum observation time" = Minimum observation time under conditions entered (13) “Data acquisition interval” = Check the data acquisition interval entered as a condition, (14) “Elevation angle” = Check the condition elevation angle (altitude angle), (15) “Duplicate session” = Check if there is an adjacent session in all sessions.

In step S63, it is checked whether various information such as an average map and session information prepared in the observation plan satisfy various standards defined in the work rules.
In step S64, the result of the check calculation is, for example,
As shown in FIG. 29, it is displayed on the display 6.
In the next step S65, it is determined whether or not to display the calculation result in detail. In the case of the detailed display, the detailed display process is performed in step S66, and the process proceeds to step S67. Otherwise, the process directly proceeds to step S67. . Then, in a step S67, it is determined whether or not to print the calculation result,
When printing, the calculation result is printed out from the printer 13 in step S68, and this work rule restriction check processing is ended. Otherwise, the processing is immediately ended.

(3) Schedule Creation System In GPS surveying, the number of GPS antennas and receivers (GPS devices) that can be prepared for a planned session is limited. Corresponding to the drafted session plan at the required time at the required measuring point. In one embodiment of the present invention, a function of determining an arrangement schedule of a plurality of GPS devices and a timer for setting automatic observation information of each GPS device in accordance with session plan data created in a session plan creation stage. A schedule creation system having functions and the like can be constructed.

FIG. 30 is a functional block diagram showing a schematic function in a schedule creation stage according to one embodiment of the present invention. Mainly, a functional block B6 in the functional block diagram of the whole system shown in FIGS. Corresponds to the function. In this example, the session plan creation system includes a receiver arrangement creation block KB1, a timer registration block KB2, and a schedule table printing block KB6. Briefly referring to FIG. 30, the schedule creation system according to one embodiment of the present invention is based on the observation condition information, the coordinate information of the observation point, and the attribute information.
When the session plan information indicating the shape of the session and the observation time is generated, the GPS plan information is generated according to a predetermined rule based on the usage conditions of the GPS receiver and the session plan information.
Schedule information relating to the arrangement and operation of the receiver is generated (KB1). The created schedule information (timer information) is transferred to the GPS receiver 9 (KB2).
Based on the schedule information, a schedule table representing an observation schedule is created for each session or each GPS receiver (KB2).

In the receiver arrangement creation block KB1, how the plurality of receivers (GPS devices) 9 are arranged based on the session information such as the shape and date and time of the session created in the session plan creation stage. It is planned whether to go, schedule information (receiver arrangement information) corresponding to this is generated, and handed over to the timer registration block KB2 together with the session information.

In the timer registration block KB2, timer information relating to the automatic observation time of each receiver is generated based on the session information and the receiver arrangement information, and is transferred to each of the plurality of receivers (GPS devices) 9. And
Each GPS device 9 automatically registers the transferred timer information.

In the schedule table printing block KB3,
A print instruction such as a schedule table based on the schedule information (receiver arrangement information) handed from the receiver arrangement creation block KB1 is issued. In response to this instruction, the printer 13
Prints a schedule table or the like based on schedule information (receiver arrangement information).

[Receiver Arrangement Processing] FIG. 31 and FIG.
5 is a flowchart illustrating a receiver arrangement process executed in the schedule creation system according to one embodiment of the present invention. In the first step K1 of this processing flow,
It is determined whether or not a session has been set. If a session has been set (YES), the process proceeds to step K2. If not, a cancel process is performed in step K3, and the receiver arrangement process ends. In step K2, it is checked whether or not the receiver number has been registered. If the receiver number has been registered (YES), the process proceeds to step K4. If not, the process proceeds to step K3 where the cancellation process is performed. finish.

When the process goes to step K4 after passing YES in both steps K1 and K2, it is determined whether or not the receiver arrangement plan is automatically created.
The process proceeds to step 9; otherwise, the process proceeds to step K10 to create a manual. At step K5, the available receivers (GPS
When the number of the (device) is selected, in the next step K6, a receiver arrangement automatic creation process for automatically and optimally arranging the receiver of the selected number is executed.

When the GPS receiver is arranged in the session, the distance between the measuring points may reach several kilometers, and so the GPS receiver is efficiently arranged in consideration of the travel time between the measuring points. It is necessary to determine the receiver arrangement schedule. For example, as shown in the upper part of FIG. 33, four sets (units) of GPS receivers R for seven measurement points A to G are provided.
When 1 to R4 are ready, the receivers R1 to R4 can be arranged in a session schedule as shown in the lower part of FIG.

That is, first, in the first session Sa,
The receivers R1 to R4 are arranged as indicated by solid lines at the four measurement points A to D, receive satellite radio waves, and perform GPS observation. Next, after observation in the first session Sa, only the two receivers R1 and R2 arranged at the previous measurement points A and B are moved to the measurement points E and F, and the four measurement points C to F Is formed, and the satellite signals are received and observed by the four receivers R1 to R4. Further, after the observation in the second session Sb, the receiver R4 arranged at the measurement point D in the first and second sessions Sa and Sb is moved to the measurement point G, and the third session including the three measurement points EG is performed. Sc is formed, and satellite radio waves are received and observed by the three receivers R1, R2, and R4.

Here, the first and second sessions Sa, S
Focusing on the relationship between b, for example, as shown in FIG. 34 (1), the receiver R1 used at the measurement point A in the first session Sa is used as a new measurement point E in the second session Sb. It is an inefficient story. In this case, as shown in FIG. 34 (2), the receivers R1 and R2 located at the measurement points A and B are changed to the measurement points F and
As used in E, it is preferable that both the receivers R1 and R2 move from the measurement points A to F and B to E with a short point-to-point distance.

The arrangement plan of the GPS receivers seems to be simple in the extremely simplified session examples as shown in FIGS. 33 and 34. However, the actual target sessions have many and many shapes. Since it is not such a simple form, it takes a long working time to manually determine such an arrangement plan.

In one embodiment of the present invention, in step K6, the optimum arrangement of the GPS receivers is automatically calculated in consideration of the distance between the constituent points in the previous and subsequent sessions. That is, the plane (x, y) of the session composing point is used as existing information.
Using the coordinates, in accordance with a predetermined receiver arrangement rule, the optimum arrangement calculation is performed so that the GPS receiver can be moved in the shortest time, considering the distance between the measurement points of the session constituent points. This receiver arrangement rule is, for example, as follows: (1) Determine the arrangement of the receivers for each of the stations forming the observation start session, and (2) set the points with the constituent points of the next session. The arrangement giving the shortest movement of the receiver is determined based on the distance, and the operation of (2) is repeated after (3).

As described above, in step K6, the optimal arrangement of the GPS receiver is automatically calculated by the automatic receiver arrangement function, and the receiver arrangement data is created. FIG. 35 shows an example of a receiver automatic arrangement screen displayed on the display 6. Therefore, the user must select the GP to use.
The optimum arrangement is automatically calculated only by selecting the S receiver, so that the receiver arrangement plan can be advanced in a short time.

When the receiver arrangement data is automatically created in step K6, it is determined in next step K7 whether or not to edit the receiver arrangement data.
Proceed to step 10 (FIG. 32) to enter the editing operation, otherwise proceed to step K8. In step K8, it is asked whether to save the created receiver arrangement data. If so, in step K9, the receiver arrangement data is stored in a predetermined storage area (or recording medium) of the external storage device 4. After the storage, the receiver arrangement processing ends. Also,
When the receiver arrangement data is not stored (discarded), the cancel processing is performed in step K3, and then the receiver arrangement processing ends.

If it is determined in step K4 that the receiver layout is to be manually created, and if it is determined in step K7 that the receiver layout data is to be edited, the process proceeds to step K10 (FIG. 32) to manually create / edit the receiver layout. to go into. First, in step K10, a session is selected, in the next step K11, a station number is selected, and in the next step K12, the number of the GPS receiver to be arranged is selected to arrange the receivers.

Subsequently, at step K13, it is determined whether or not the GPS receiver is of "4600LS" type.
In the case of this type of GPS receiver, the process proceeds to step K15 after the process of step K14, and otherwise proceeds directly to step K15.

In step K14, "antenna height" representing the height from the observation point to the antenna is input, and a measurement method is selected. This is because the “4600LS” receiver needs to simultaneously set antenna information as timer information to be described later. Therefore, in this embodiment, a mechanism for prompting an antenna-related setting is adopted. The height up to the phase center portion in consideration of the correction value is called “vertical height”. Also, as the selected measurement method, for example, three types of methods are prepared, and there are a method of measuring the vertical height and the bottom of the antenna, and a method of obliquely measuring by hooking on a hook next to the antenna.

In step K15, it is determined whether or not a receiver is to be arranged at another measuring point of the session. If it is necessary to arrange the receiver, the flow returns to step K11 to return to step K1.
By repeating the processing of 1 to K15, the GPS receivers are sequentially manually arranged at the respective measurement points of the session. When the receiver arrangement is no longer necessary, the process proceeds to step K16, where it is determined whether or not the receiver is to be arranged at another session configuration point. If the receiver arrangement is necessary, the process returns to step K10. By repeating the processing of steps K10 to K16, the GP for the constituent points of each session
The arrangement of the S receiver is sequentially determined manually.

If it is determined in the next step K16 that there is no need to arrange receivers at other session constituent points, the process proceeds to step K8 (FIG. 31), and receiver arrangement information (manually created in steps K10 to K16) You will be asked if you want to save the schedule information), and if you want to save it,
After storing the session plan data as schedule information in a predetermined storage area (or recording medium) of the external storage device 4 in step K9, the receiver arrangement processing ends. If the data is not to be saved (discarded), the cancel processing is performed in step K3, and then the receiver arrangement processing ends.

[Timer Registration Processing] In GPS surveying, it is necessary to use at least two or more GPS receivers in one session, so that at least two persons are required to manage the status of each receiver. In the case of performing nighttime observation with a smaller number of people, a timer is often set for each GPS receiver to perform automatic observation. As described above, when performing automatic observation in GPS surveying, generally, a timer is manually set for each GPS receiver. However, when manually setting each receiver, the timer information is set for each session. You must register. That is, it is necessary to manually set observation plan information for each session for each receiver. Further, in some receivers, the timer setting screen is displayed in English, so that the efficiency is extremely low and an operation error is likely to occur.

In one embodiment of the present invention, each GP is determined from existing session information (configuration point, observation date and time, session name, etc.) and receiver arrangement information (schedule information).
Timer information for performing automatic observation is generated for each S receiver, and the timer information is transmitted to each GP by the timer transfer function.
It is transferred to the S receiver and registered automatically. Therefore, the user connects the GPS receiver (GPS device) and the host computer via communication means such as RS232C,
Observation preparation work can be efficiently performed simply by performing the work of transferring the timer information. FIG. 36 is a flowchart showing a timer registration process executed in the schedule creation system according to one embodiment of the present invention.

In the first step K21 of this processing flow, it is checked whether or not a session has been set, and if a session has been set (YES), the process proceeds to step K2.
If not, end processing is performed in step K23 and the timer registration processing is immediately ended. Step K22
Then, it is checked whether or not the GPS receiver (GPS device) 9 is prepared so that it can be arranged.
The process proceeds to step S4, but if not, the process ends through step K23.

In step K24, a session scheduled to be observed is selected from the set sessions, and in the next step K25, the number of the receiver to be registered in the timer is selected from the GPS receivers ready for placement, and the process proceeds to step K25. Go to K26. In step K26, it is checked whether or not there is a change in the communication settings for the GPS receiver whose number has been selected. If there is a change, the process proceeds to step K27, the communication settings are changed, and then the process proceeds to step K28. K
Proceed to 28. In step K28, the session information such as the configuration point of the session, the observation date and time, and the session name, and the timer information for automatic observation generated from the receiver arrangement information (schedule information) are transferred to the GPS receiver. FIG. 37 shows an example of a timer registration screen displayed on the display 6 during the timer registration process.

After the transfer of the timer information, the next step K
At 29, it is determined whether or not there is a transfer to the other GPS receiver of the session, and if there is a receiver to be transferred by the timer, the process returns to step K25 to repeat the processing of steps K25 to K29, and The timer information is sequentially transferred manually to each receiver. If the timer transfer is no longer necessary, the process proceeds to step K30, where it is determined whether or not timer information has been transferred for another session. If so, the process returns to step K24 to perform the processes of steps K24 to K30. Repeatedly, the timer information is sequentially transferred and registered to the GPS receiver to be arranged for each session. Then, in step K30, when it is determined that the timer transfer is not necessary for another session, the timer registration processing ends.

[Scheduling Table Print Processing] In the GPS survey, after the observation plan is completed, before the observation is actually performed on site, an observation schedule table is prepared which summarizes the observation date and time of the session, the receiver number used, and the like. I do. In order to create such a schedule, the movement information of each GPS receiver and the information of each session observation time are generally expressed by:
It is created by hand and is very inefficient.

In one embodiment of the present invention, the system is provided with a schedule table creation function, and existing session information (configuration point, observation date and time, session name, etc.) and receiver arrangement information (including antenna height and measurement method) are provided. In consideration of the above, a schedule table can be automatically created for each session or each GPS receiver. Therefore, this table creation function allows the user to efficiently proceed with the work of creating a schedule table and the like.

FIG. 38 is a flowchart showing a printing process of a schedule table or the like executed in the schedule creating system according to one embodiment of the present invention. In the first step K31 of this processing flow, it is checked whether or not a session has been set. If a session has been set (YES), the flow proceeds to step K32; otherwise, the end processing is performed in step K33 and the schedule is immediately set. The printing process for the table etc. ends. In step K32, it is determined whether to print the schedule table in units of GPS receivers (GPS devices) or in units of sessions. If the schedule is in units of receiver, the process proceeds to steps K34 to K35. Go to -K37.

When a desired receiver is selected in step K34, a printing process for each selected receiver is executed in step K35. When a desired session is selected in step K36, print processing is executed in units of the selected session in step K37. Then, after executing the processing of steps K35 and K37, the printing processing of the schedule table etc. is ended. FIG. 39 shows an example of a schedule table output from the printer 13 by a print processing such as a schedule table.

(4) Baseline Analysis Calculation System In the GPS survey, after the site observation, the work of creating the result is performed using the data acquired by receiving the satellite radio wave.
Some rules also occur in each work in the output creation stage. For example, in the baseline analysis for calculating a three-dimensional vector, the order of calculation such as what measurement point in which session should be started, or what the start point / end point should be in each vector, and calculation of a certain vector or session There are unique rules such as sending calculation results such as passing results (coordinate values) to adjacent vectors and sessions and calculating.

In one embodiment of the present invention, information registered and generated based on an observation plan is transferred not only to on-site observation work but also to a result creation work such as baseline analysis, and various work rules are automatically set. It is possible to construct a baseline analysis calculation system that realizes a mechanism of calculating by the above.
In this baseline analysis calculation system, after reading the observation data, the analysis can be immediately performed by the analysis plan information automatic generation function, so that even a non-expert user can efficiently proceed with the result creation work.

FIG. 40 is a functional block diagram showing a schematic function at a baseline analysis calculation stage according to an embodiment of the present invention. Mainly, a functional block B7 in the functional block diagrams of the whole system shown in FIGS. Corresponding to the function of. Briefly referring to FIG. 40, the baseline analysis calculation system according to one embodiment of the present invention
Obtained from the receiver 9, performs matching processing with the existing session information (AB1), and generates analysis plan information (representing the setting state of the analysis calculation) according to the result of the matching processing (AB)
3, AB4). In other words, after the matching process, considering the existing observation plan information such as the attribute of the measurement point (point attribute), the shape of the session or the observation time (date and time), the setting of the reference station in each session, the analysis order of the session, and the Automatically calculates analysis plan information such as the order of the baseline to be analyzed and the baseline direction.

In the functional block AB1, the observation data (GPSL1, L2) acquired by the GPS device 9 is received, and the data (internal processing / station number, Perform matching processing (such as observation time). With this matching process, the order of analysis and the like can be determined by applying observation data to the session shape created at the planning stage. In the next edit block AB2, the observation data and / or the session plan data are edited as necessary. For example, if there is no observation plan or observations are made using a method different from the observation plan, a session shape is created and edited, and both data are matched.

When the observation and plan data are matched by the processing of the functional blocks AB1 and AB2, the functional block AB
At 3, the analysis plan information for setting analysis calculation conditions such as the analysis order of the session and the baseline, the reference station of each session (for example, the setting of the reference station in each session, the analysis order of the session, the analysis order of the baseline for each session, Base line direction), and the analysis plan information is stored in the function block A.
Edit in B4 if necessary. And the functional block A
At B5, an automatic baseline analysis calculation is executed based on the analysis plan information.

FIGS. 41 and 42 are flowcharts showing a baseline analysis calculation process executed in the baseline analysis calculation system according to one embodiment of the present invention. When the observation data from the GPS device (GPS receiver) 9 is read into the system in the first step A1 of this processing flow, the matching process is automatically started. When the automatic matching process is executed in step A2, the reference station is set in each session according to a predetermined calculation rule in consideration of the existing observation plan information (point attributes, session configuration points, session configuration baseline, session observation date and time, etc.). The analysis plan information such as the session analysis order, the analysis baseline order for each session, and the baseline direction is automatically generated.

In the next step A3, it is determined whether or not the matching process is good. If the matching process is good, the process proceeds to step A4, and if not, the process proceeds to step A5. Step A
In step 5, it is searched whether or not there is plan data corresponding to the observation data. If there is no plan data, the process proceeds to step A6 to reset the plan data and returns to the joining process in step A2. On the other hand, if there is plan data, step A5
Then, the process proceeds to step A7, where it is determined whether or not the defective plan data is to be deleted. If there is any data to be deleted, the data is deleted in step A8, and the process returns to the joining process in step A2. If there is no data to delete,
It returns to the joining process of step A2. In this way, the processing of steps A2 to A8 is repeated as appropriate according to the result of the alignment processing. When a good alignment result is obtained in step A3, the automatic alignment processing is terminated in step A4, and the process proceeds to step A9.

In step A9, it is determined whether or not to edit the observation and plan data.
Step A1 after editing observation and planning data at 0
Go to step 1, otherwise go directly to step A11. In step A11, it is determined whether there is a change in the analysis direction in the entire session. If there is a change, in step A12, the changed analysis direction is set, and the process proceeds to step A13 (FIG. 42). If so, the process proceeds directly to step A13. Note that the analysis direction of the entire session includes types such as “clockwise”, “counterclockwise”, and “radial”.

When data matching is completed and the analysis direction is determined, it is determined in step A13 whether or not there is a change in the analysis plan. This analysis plan refers to a function of individually setting and editing analysis plan information (session analysis order, baseline analysis order, reference station of each session, etc.) determined by data matching and analysis direction. Here, if there is a change in the analysis plan, in step A14, the changed analysis plan is set and the process proceeds to step A15. Otherwise, the process directly proceeds to step A15.

In step A15, it is determined whether there is a change in the analysis conditions. These analysis conditions include conditions such as the setting of the altitude angle.
For example, when the set altitude angle is “20 degrees”, observation data acquired at an altitude angle of 20 degrees or less is not used for subsequent calculations. Here, if there is a change in the analysis plan, the changed analysis conditions are set in step A16, and the process proceeds to step A17.
Proceed to. When the analysis direction, the analysis plan, and the analysis conditions are determined in this way, the baseline analysis is performed in step A17.

[Baseline Analysis Process] In general, in the baseline analysis for calculating a three-dimensional vector, the calculation proceeds according to a predetermined rule. For example, in FIGS. 43 (1) and 43 (2),
In the first session Sa, the baseline A-B is analyzed using the measuring point A as a reference station of the whole session, and then the baseline A is analyzed.
The base line BC is analyzed based on the coordinates of the measurement point B, which is the analysis calculation result of -B. Similarly, based on the analysis calculation result of the baseline BC (coordinate of the measurement point C), the baseline CD is changed to the baseline C
Based on the analysis result of -D, the baseline DA is sequentially analyzed.

In the next second session Sb, for example, as shown in FIG. 43A, when the measuring point E is set to the reference station,
The base line EF is analyzed and calculated on the basis of the coordinates of the reference station E. In this setting, since the reference station E analyzes a single positioning value (coordinates), the relationship with the first session Sa (request for coordinates). ) Does not hold (NG). On the other hand, as shown in FIG. 43 (2), when the measurement point C is set as the reference station in the second session Sb, based on the coordinates of the measurement point C which is the calculation result of the baseline BC analyzed in the first session Sa. As a result, the relationship between the first session and the coordinate transfer is established (OK).

In FIG. 43 (3), if the session Sd is analyzed instead of the sessions Sb and Sc, for example, after the baseline analysis of the session Sa, the transfer to the session Sd is not established (NG). Furthermore, even if the second session Sb is analyzed and calculated after the baseline analysis of the first session Sa, the first session S
In the case a, where the base line B → C is to be analyzed, for example, as indicated by an arrow X, the base line C → B is analyzed.
An offer to the session Sb is not established (N
G). Also, in the session Sc, if the base line HE is analyzed next to the base line CG and not the base line GH, for example, as shown by an arrow Y, the transfer to the measurement point H is not established (NG) .

Thus, for example, for the session shape of FIG. 26, as shown in FIG. 44, the given point A with the existing coordinate value is set as the reference station which is the calculation start point of the first session, and A clockwise analysis is performed such that the base line AB around the next measurement point B is analyzed, and the next base line BC is analyzed using the coordinates of the measurement point B on the analyzed base line AB. Calculate with In the baseline analysis in the next second session Sb, the measurement points C already obtained in the analysis in the first session are used.
Is the reference station of the calculation start point, and based on the coordinates of the measurement point C,
The analysis proceeds sequentially from the baseline CD in a clockwise direction.

In other words, when the baseline analysis is performed, the calculation proceeds in principle according to the following rules: (1) The result table coordinates (value on the Bessel ellipsoid) of one measurement point are calculated on the WGS84 ellipsoid. (2) Set the analysis reference station in consideration of the transfer of the calculation result coordinates in session units, and (3) Set the session in consideration of the transfer of the calculation result coordinates. (4) setting the analysis order of the base line in consideration of the transfer of the calculation result coordinates, (5) setting the base line direction in consideration of the transfer of the calculation result coordinates, and the like.

However, in order to proceed with the calculation of the baseline analysis in accordance with such various rules, considerable specialized knowledge is required, and the calculation operation cannot be efficiently promoted. Therefore, in one embodiment of the present invention, step A
In step 2, after the automatic matching process, considering the existing observation plan information (point attributes, session configuration points, session configuration baseline, session observation date and time, etc.), the reference station setting in each session, session Analysis plan information such as an analysis order, an analysis baseline order for each session, and a baseline direction is automatically generated. FIG. 45 shows an example of an analysis plan information automatic generation screen displayed on the display 6.

The calculation rules for the automatic generation of the analysis plan information are, for example, as follows: (1) A station having a point attribute as a reference station is set as a reference station of all sessions, and a session including the point is changed from a session including the point to a session of the session. Determine analysis order. (2) From reference station in session,
The base line direction is determined based on existing selection conditions (clockwise, counterclockwise, radial). (3) An adjacent session is set as a session to be analyzed next, and a station adjacent to the previous session is set as a reference station of the next session. And repeat (2).

Step A17 is performed using such analysis plan information.
When the baseline analysis is performed at, in the next step A18,
It is checked whether the result of the baseline analysis is normal. This check is, for example, normal (eg, “Fix”) or defective (eg, “Float”) on the analysis plan information automatic generation screen of the display 6 for each baseline.
Is displayed, and in the case of a failure, a warning message is displayed during the baseline analysis to prompt the user to select whether or not to continue the baseline analysis. If the result of the analysis is not normal, step A1
Returning to step 5, the processing of steps A15 to A18 is repeated until the analysis result is determined to be good.

If it is determined in step A17 that the analysis result is normal (good), the flow advances to step A19 to determine whether there is another observation data to be analyzed for the baseline. Returning to A1, the processing of steps A1 to A19 is repeated for the observation data. Then, when it is determined in step A19 that there is no observation data, the baseline analysis calculation processing ends.

As described above, in the baseline analysis calculation system, in step A2, the observation plan information such as the point attribute and the shape / date and time of the session is considered by the analysis plan information automatic generation processing executed after the automatic matching processing. Then, the settings of the reference station in each session, the analysis order of the sessions, the analysis baseline order for each session, the baseline direction, and the like are automatically calculated, and the corresponding baseline analysis plan information is automatically generated. In addition, even if the observation plan is not set or the observation is performed by a method different from the observation plan,
By creating and editing session shapes, it is also possible to automatically calculate various analysis plan information. Therefore, since the analysis can be performed immediately after reading the observation data, even a user who is not an expert can efficiently proceed with the result creation work.
