The tip 3a, which is the lower end of the, is formed by the driving head 32. A pole accommodating portion 3s is formed in a substantially cylindrical space inside the main body 3 of the upper main body 30 portion. In the pole accommodating portion 3s, a GPS device 5 that constitutes a point positioning means in the surveying device 1 is provided. The possessed pole 6 is fitted in such a manner that the axis CL2 of the pole 6 is aligned with the axis CL1 of the pile 2 and is oriented in the vertical direction. The GPS device 5 has a receiving antenna 5a,
The antenna center C0 of the receiving antenna 5a is set at a position separated from the lower end of the pole 6 by a predetermined distance. Therefore, the main body 3 of the pile 2 can support the pole 6 in such a manner that the receiving antenna 5a of the GPS device 5 is held at a position where the antenna center C0 forms a predetermined height H2 from the tip 3a. There is. A receiver 51 is connected to the receiving antenna 5a via a cable or the like, and the receiver 51 receives the positioning signal S by causing the receiving antenna 5a to receive positioning signals S from a plurality of satellites.

Is formed such that the upper end portion of the upper body 30 projects radially outward from the portion of the upper body 30 other than the flange portion 31. A hole communicating with the pole accommodating portion 3s is formed in the center of the flange portion 31. Therefore, the pole 6 of the GPS device 5 has a hole formed in the center of the flange portion 31. It can be inserted into and removed from the pole housing portion 3s via the pole housing portion 3s.

On the other hand, as described above, the placing head 32 provided at the lower end of the main body 3 has the screw 3 as shown in FIG.
It is attached to the main body 3 in a detachable manner via b or the like, and inside the placing head 32, an element accommodating portion 32s is formed in a space shape as a memory element accommodating portion. . The element accommodating portion 32s accommodates the storage element 7 as a storage unit that can store the point information INF, which is the position information of the point where the main body 3 is placed, in the form fixed and arranged via the cushioning material 8. Therefore, the memory element 7 is detachably attached to the main body 3 in a form arranged below the pole housing portion 3s.

As shown in FIG. 2, the memory element 7 has a tray 9 made of a magnetically transparent resin material formed in a shallow container shape, and a groove 9s is formed inside the tray 9. ing. In the groove 9s, a magnetostrictive strip 10 made of a thin plate-shaped amorphous metal magnetostrictive material (amorphous or the like) is not adhered to the tray 9 (that is, the magnetostrictive strip 10). Is housed and held in the groove 9s so that it can be mechanically vibrated, and a hard ferromagnetic material (magnetic stainless steel, nickel, ferrite, etc.) is provided on the upper side of the magnetostrictive strip 10 (that is, on the pole housing 3s side). )
A plate 11 formed by a plate shape covers the groove 9s in which the magnetostrictive strip 10 is accommodated, and the tray 9
It is provided by being joined to. The plate 11 is adapted to provide a magnetic bias to the magnetostrictive strip 10 when it is magnetized.
Can be magnetized to form a plurality of magnetic patterns. Therefore, the memory element 7 uses the plate 11 provided on the pole accommodation portion 3s side as an input / output portion, and the information formed by the groove 9s and the magnetostrictive strip 10 connected to the plate 11 via the upper surface 11a thereof. The storage unit can store and store unique spot information INF, and the spot information INF is formed in a predetermined magnetic pattern that differs depending on the magnetization of the plate 11.

On the other hand, on the pole 6 of the GPS device 5,
As shown in FIG. 1, an electromagnetic read / write head 12 is attached to the lower end of the pole 6 so that the point information INF stored in the storage element 7 can be read and written, that is, storage means on the pile 2 side. The GPS device 5 and the read / write head 12 are electrically connected to each other via the input / output device 13 which is position information input / output means. There is. As shown in FIG. 1, the input / output device 13 has a main control unit 15, and the main control unit 15 includes a coordinate information writing unit 16 and a D / A conversion unit 1.
7, an output unit 19, a coordinate information reading unit 20, an A / D conversion unit 21, an input unit 22 and the like are connected. The input unit 2
A receiver 51 of the GPS device 5 is connected to 2.

Since the surveying instrument 1 and the piles 2 and the like constituting the surveying instrument 1 have the above-mentioned configuration, the surveying instrument 1
When performing survey work using the
As soon as the pile 2 is installed at the measurement point Pn, the position (Xn, Yn, Zn) of the measurement point Pn is set as the position data DAT1.
And the position (Xn,
Yn, Zn) point information INF that is position information indicating the value of
To memorize. At this time, the measurement point Pn is the position of the tip 3a of the main body 3 of the pile 2 which is buried at the position corresponding to the depth H1 below the ground surface 39a.
Since the pile 2 is set in the survey site 39, first, the pile 2 is driven so that the tip 3a of the pile 2 is located at the predetermined depth H1. That is, at an arbitrary point where positioning is desired, a predetermined depth H1 from below the ground surface 39a.
Is defined as a measurement point Pn.

Therefore, first, as shown in FIG.
The main body 3 of the pile 2 is mounted at the position where the measuring point Pn is desired to be set, and the driving head 32 is mounted on the lower side of the upper main body 30.
In a state where the memory element 7 is arranged in the second element housing portion 32s, it is driven by hammering it from the ground 39a into the ground 38 with a hammer 37 or the like. It should be noted that the mark 3 is provided on the outer periphery of the body 3 at a position forming a distance H1 in the axial direction from the tip 3a.
By marking p (shown in FIG. 4 (a)), it is easy to adjust the driving depth of the main body 3 so that the tip 3a is buried at a position having a depth H1 from the ground 39a. I can. Further, the storage element 7 is the element housing portion 32s of the driving head 32.
Since it is disposed inside together with the cushioning material 8, it is not destroyed by impact during driving. In this way, at the position where the main body 3 of the pile 2 is placed, the measuring point Pn is arranged by the tip 3a of the main body 3 at a position forming the depth H1 below the ground 39a at the pile placing position. The pole accommodating portion 3s is formed and arranged at the measurement point Pn with the axis CL1 oriented vertically.

Therefore, the pile 2 is driven at an arbitrary point in this way, and the position having the depth H1 from the driving point is measured at the measurement point Pn.
As shown in FIG. 3 (b), the GPS is set in the pole accommodating portion 3s of the main body 3 prepared at the measurement point Pn.
The pole 6 of the device 5 is fitted. Then, the GPS device 5
Is a shape in which the axis CL2 of the pole 6 is aligned vertically with the axis CL1 of the pile 2 and the antenna center C0 of the receiving antenna 5a is at a predetermined height H from the position of the tip 3a of the pile 2.
It is supported by the main body 3 while being held in the two positions. That is, the GPS device 5 is installed at the measurement point Pn. Here, the receiver 51 is connected to the receiving antenna 5a, and the read / write head 12 mounted on the lower end of the pole 6 is connected.
When the GPS device 5 is electrically connected via the input / output device 13, the preparation for the surveying work by the surveying device 1 is completed.

Thus, as shown in FIG. 3B, the pile 2
When the pole 6 of the GPS device 5 is inserted into and supported by the main body 3 of the vehicle, the read / write head 12 attached to the lower end of the pole 6
Has a shape which faces the storage element 7 mounted on the tip 3a of the main body 3 in a non-contact manner. That is, in this state, the storage element 7
Is prepared by the input / output device 13 so that the point information INF can be read and written from the read / write head 12. In this way, the survey preparation work at the measurement point Pn is simply performed by the pole 6
The receiving antenna 5a is retained, the storage element 7 and the read / write head 1 are simply inserted into the pole housing portion 3s of the main body 3.
The opposing arrangement with 2 can be easily performed at the same time.

Next, the receiving antenna 5 is received by the receiver 51.
A is made to receive the positioning signals S from a plurality of orbiting satellites for surveying. Then, the GPS device 5 analyzes and calculates the plurality of positioning signals S received by the receiving antenna 5a by the receiver 51, and thereby the positions of the plurality of satellites and the positions of the positioning signals S received with each of the satellites. The current position of the antenna center C0 can be obtained based on each distance between them. At this time, since the antenna center C0 is located at a position having a predetermined height H2 in the vertical direction from the tip 3a of the pile 2, the height from the coordinate values on the X, Y, and Z axis systems that represent the current position of the antenna center. H
The coordinate value obtained by subtracting 2 is the coordinate position (Xn, Y
n, Zn). Therefore, the GPS device 5
The position (Xn, Yn, Zn) of the measurement point Pn is detected as position data DAT1.

Then, the main controller 15 of the input / output device 13
Reads the position data DAT1 detected by the GPS device 5 from the input unit 22. Then, the main control unit 15 operates the coordinate information writing unit 16, causes the D / A conversion unit 17 to convert the position data DAT1 into a write signal SP1, and causes the output unit 19 to output the write signal SP1. The read / write head 12 is controlled and operated. Then, the read / write head 12 generates a magnetic field according to the write signal SP1. At this time, the read / write head 12 has the main body 3
Since the storage element 7 and the storage element 7 are arranged so as to face each other with the storage element sandwiched therebetween, the plate 11 of the storage element 7 is magnetized by the magnetization pattern generated by the read / write head 12.
As a result, the storage element 7 stores the position data DAT1 detected by the receiver 51 in advance in such a manner that the plate 11 serves as an input unit and the groove 9s and the magnetostrictive strip 10 serve as an information storage unit. Remember in shape.

In this way, the measuring point Pn is set by the main body 3 of the pile 2 placed at an arbitrary point, and the GPS device 5 installed at the measuring point Pn using the pile 2 sets the measuring point Pn. The position (Xn, Yn, Zn) of the measuring point Pn at the placement position can be directly measured by using GPS, and the position (Xn, Y) of the detected measuring point Pn can be easily detected.
position data DAT1 representing (n, Zn)
The data can be stored in the storage element 7 in the form of NF at once. That is, in this state, the pile 2 is the point information INF of the measuring point Pn where the tip 3a is located by the storage element 7 provided in the driving head 32 forming the tip 3a of the main body 3.
Is stored and stored at the measuring point Pn.

Therefore, until the pole 6 of the GPS device 5 is removed from the pole accommodating portion 3s of the pile 2 thus installed and the pile 2 is required again, as shown in FIG. 3 (c). Then, the pole accommodating portion 3s is covered with the cap 4. Then, the main body 3 of the pile 2 is in a state where mud or the like does not accumulate on the pole accommodating portion 3s and the pole 6 can be immediately inserted by removing the cap 4, and as described above, the pile 2 Is stored at the measurement point Pn in a state in which the point information INF of the measurement point Pn on which is placed is stored.

Thus, in this way, the main body 3 of the plurality of piles 2 is driven in the survey site 39, and the piles 2 are supported by the receiving antenna 5a provided on the pole 6 supported by the main body 3.
The coordinate position (Xn, Yn, Zn) is determined with the position forming the point Hn below the ground surface 39a at the point where is set, and the determined coordinate position (Xn, Yn, Zn) is determined as the point information INF. A large number of piles 2 are installed in a state of being stored in the storage element 7 as. Then, when the pile 2 is required during the surveying work, a specific pile 2 is selected, and the position (Xn, Yn, Zn) of the measurement point Pn indicated by the pile 2 is stored in the storage element 7.
Can be easily read from.

For this purpose, the cap 4 is removed from the main body 3 of the required pile 2, and the pole accommodating portion 3s opened by this is opened.
Then, the pole 6 provided with the receiving antenna 5a of the GPS device 5 is fitted and supported again. In this state, the input / output device 1
The coordinate information reading unit 20 is operated by the main control unit 15 via the control unit 3. Then, the coordinate information reading unit 20 operates the read / write head 12 to generate a magnetic field. At this time,
That is, in the fitted state of the pole 6, the read / write head 12
As described above, the storage element 7 arranged at the position opposite to the storage element 7 is magnetized in the magnetization pattern corresponding to the position data DAT1 of the measurement point Pn.
In the groove 9 s, a magnetic bias corresponding to the magnetization pattern is applied in the groove 9 s, so that the magnetic field generated by the read / write head 12 resonates with a predetermined vibration characteristic as described above.

Therefore, the main controller 15 of the input / output device 13
Activates the coordinate information reading unit 20 to read the vibration characteristic of the magnetostrictive strip 10 via the read / write head 12. That is, the change state of the induced voltage formed by the resonance of the magnetostrictive strip 10 is input to the input unit 22 as an electrical read signal SP2. The main control unit 13 of the input / output device 13 that receives this transmits the read signal SP2 input to the input unit 22 to the A / D conversion unit 21, and converts the read signal SP2 into digital data. Then, the read signal SP2 read by the read / write head 12 has a form corresponding to the point information INF stored in the magnetostrictive strip 10 held in the groove 9s, and thus the coordinate information reading unit 2 as described above.
A signal obtained by converting the read signal SP2 obtained by 0 into digital data is stored in the storage element 7 as the point information INF.
Position data DAT1 stored and held therein, that is, the measurement point P
It corresponds to the position of n (Xn, Yn, Zn). In this way, the input / output device 13 positions the measurement point Pn (Xn, Y) indicated by the predetermined pile 2 arbitrarily selected from the large number of piles 2.
(n, Zn) can be easily read and detected.

Therefore, if the surveying instrument 1 is used, the position where the pile 2 is installed in the surveying site 39, that is, the position (Xn, Yn, Zn) of the surveying point Pn can be easily known. It is not necessary to record and manage the driving positions of the piles 2 using a field notebook or a recording device, and to compare the piles and their positions on the record with the existing piles 2 at the survey site 39, as in the conventional case. . Further, since the recording element 7 is provided with the plate 11 which is an input / output section thereof on the pole accommodation section 3s side, the read / write head 12 is arranged in the pole accommodation section 13 so that the read / write head 12 is The point information INF can be easily rewritten via the connected input / output device 13. Therefore, FIG.
As shown by the dotted line in (c), if only the predetermined area 38m of the ground 38 moves at the survey site 39, and the position of the measuring point Pn indicated by the pile 2 changes accordingly, it is easy to do so. You can rewrite this. Further, even when the work at one site is completed and the pile 2 is diverted to another site, the point information INF stored and stored in the storage element 7 can be easily rewritten. The storage element 7 is
By removing the setting head 32 from the upper main body 30, the setting head 32 can be attached / detached to / from the main body 3. Therefore, it is also possible to store the predetermined point information INF in the storage element 7 in advance and then set at the measurement point Pn. It is possible.

In the above-mentioned embodiment, the storage means for storing the position of the point where the pile 2 is driven is the magnetostrictive strip 10 and the plate 1 held in the groove 9s.
Although the example of the storage element 7 using 1 is described above, the configuration of the storage means is not limited to this, and for example, an IC
It may be an integrated circuit such as a memory or another memory chip. In addition, point information INF to the storage means
The input / output method may be other than the method described in the embodiment. Further, in the embodiment, the driving head 32 is detachably attached to the main body 3 via the screw 3b at the tip 3a which is the lower end of the driving body 3, and the element housing portion of the driving head 32 is attached. The example in which the storage element 7 is arranged in 32s has been described, but the driving head 32 may be integrated with the main body 3 as long as it can function as a driving portion at the lower end of the main body 3. , It doesn't have to be removable. Further, the storage element 7 may be disposed at a position other than that described in the embodiment, and may not necessarily be removable from the main body 3. Further, in the embodiment, the pile 2 is connected to the GPS device 5
Also used together, the pole 6 provided with the receiving antenna 5a is fitted into the pole housing portion 3s, and the read / write head 12 attached to the lower end of the pole 6 and the GPS device 5 are connected via the input / output device 13. Although the example in which it is used is described, the pile 2 is not used only for such a GPS surveying technique, but is applicable to all surveying operations using surveying poles such as the pole 6. Also, in the embodiment,
Using the pile 2, the pile 2 is driven at an arbitrary point to be surveyed, the position of the tip 3a is set as the measurement point Pn, and the position (Xn, Yn, Zn) of the measurement point Pn is detected, and The example in which the value is stored in the storage element 7 as the point information INF has been described, but the pile 2 is placed at a point whose coordinate position is known in advance, and the position of the point is stored in the storage element 7. Of course, you can use it to keep it.

[0026]

As described above, according to the present invention, the main body 3 is provided with the driving portion such as the driving head 32 provided at the lower end of the tip 3a and the like, and the pole accommodating portion 3s is provided in the main body 3.
And a measuring point P on which the main body 3 is placed.
A storage unit such as a storage element 7 capable of storing position information such as spot information INF of a spot such as n is provided, and the storage unit includes an input / output unit such as a plate 11 provided on the side of the pole housing 3s, Since the survey piles such as the piles 2 are constituted by the information storage units such as the grooves 9s and the magnetostrictive strips 10 connected to the input / output unit, the storage means is installed in the pole storage unit by placing the main body 3 therein. The position information of the point where the main body 3 is placed can be arranged and held in the information storage section via the input / output section in a freely input / output state. Therefore, the main body 3 is stored in the storage means of the survey pile placed at an arbitrary point.
If the position information of the point where the stake is placed is stored, the position of the point where the survey pile is placed can be known only by reading the position information from the storage means. At this time, since the input / output unit of the storage means is provided on the side of the pole housing portion 3s, only the head such as the read / write head 12 of the appropriate information reading means corresponding to the storage means is arranged in the pole housing portion 3s. Thus, it is possible to easily detect the position information of the point where the survey pile is placed. Further, the position of the point where the main body 3 is placed should be easily detected by using a pole such as the pole 6 housed in the pole housing 3s or a receiving antenna 5a of the GPS device 5 provided on the pole. Can be done. Then, the position information indicating the detected position of the main body 3 can be stored in the information storage unit of the storage unit by inputting from the input / output unit. That is, it is possible to easily read and write the position information, that is, change the position information. Therefore, like a conventional survey pile, its placement position is obtained by surveying, the obtained position is recorded in a field notebook or recording device, and the surveying recorded on the field notebook or recording device is performed for each surveying operation. It is not necessary to check the piles and their placement positions with the local survey piles. That is, since the position of each survey pile can be easily found on site, the labor required for survey work can be simplified. Further, it is easy to correct the position information stored in the recording means. As a result, the factors that cause the risk of errors when selecting survey piles and their positions are reduced as much as possible, and the reliability of surveying is improved.

Further, in the present invention, when the storage means such as the storage element 7 is arranged below the pole accommodating portion 3s, a storage means is provided via the main body 3 located at the bottom of the pole accommodating portion 3s. The pole housing portions 3s can be arranged to face each other. At this time, the input / output section of the storage means is provided on the pole accommodating section side as described above. Then, by inserting a pole such as a pole 6 having a head such as the read / write head 12 at the lower end thereof into the pole accommodating portion 3s, the point information INF or the like is transmitted via the input / output device 13 connected to the head. The position information can be input to or output from the input / output unit to the information storage unit. That is, it is possible to easily write or read the position information of the surveying pile setting point in the storage means while the surveying pile is driven and the pole is installed at the surveying pile setting point. . As a result, the position of the survey pile can be more easily and surely grasped, and the position information can be easily rewritten, so that the survey work becomes even more efficient.

Further, in the present invention, when the storage means such as the storage element 7 is detachably provided to the main body 3,
The spot information I is stored in the storage means in a state of being removed from the main body 3.
Positional information such as NF can be stored. That is, before driving the survey pile, the storage means is stored with predetermined position information in advance, and then the storage means is attached to the main body, and the predetermined position corresponding to the position information stored in the storage means is set. It is also possible to drive survey piles. That is, the position information can be read and written without the installation of the survey pile. This will broaden the application of survey piles. Further, as described above, since the position information can be read from and written to the storage element by the information read / write heads other than the read / write head 12 arranged in the pole accommodating portion 3s, the shape of the head is not limited by the pole accommodating portion 3s. Of course, the storage means can be exchanged, and the storage means whose operation state is dull or the deteriorated storage means can be replaced with another storage means.

Further, in the survey pile such as the pile 2 in which the storage means such as the storage element 7 is arranged below the pole accommodating portion 3s in the present invention, the main body is the upper main body in which the pole accommodating portion is formed and the driving portion. Consisting of the driving head 3
The driving portions such as 2 are provided detachably with respect to the upper main body 30 in a form in which a storage element accommodating portion such as the element accommodating portion 32s is formed, and when the storage means is arranged in the storage element accommodating portion, Since the storage means is housed in the storage element housing portion formed inside the driving part and is not exposed to the outside, the impact at the time of placing the survey pile or the survey pile at the placement point for a long time. The retention prevents the risk of damaging the storage means.
