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. Therefore, the read / write head 12 does not have to be capable of reading / writing the spot information INF to / from the storage element 7 as 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. 32s
Although the example in which the memory element 7 is arranged is described above, 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 does not 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. Furthermore, in the embodiment, an example in which the surveying device 1 is configured so that the spot positioning means is the GPS device 5 has been described. However, in the surveying device 1, the spot positioning device indicates the current position of the spot positioning device. It suffices that the pile 2 be able to perform positioning detection in a form corresponding to the current position of the positioning point Pn formed by its driving. Therefore, if the point positioning means has a pole such as the pole 6, May be used. Further, in the embodiment, 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, Z) of the measurement point Pn is set.
n) is detected, and the example in which the surveying instrument 1 is used so as to store the value as the spot information INF in the storage element 7 has been described. Of course, 2 may be set, the position of the point may be stored in the storage element 7, and may be used later to read out the point information INF if necessary.

[0026]

As described above, according to the present invention, the pole accommodating portion 3s is formed in the body 3 having the driving portion such as the driving head 32 provided at the lower end of the tip 3a and the like, and the body 3 is formed.
Is provided with a storage means such as a storage element 7 capable of storing position information such as point information INF of a point such as a measurement point Pn on which the main body 3 is placed, and the storage means is provided on the pole accommodating portion 3s side. The pole accommodating portion 3 has a surveying pile such as a pile 2 including an input / output portion such as a plate 11 and an information storage portion such as a groove 9s connected to the input / output portion and a magnetostrictive strip 10.
A point positioning means such as a GPS device 5 having a pole 6 that can be fitted in s is provided so that the current position of the point positioning means can be detected and the read / write head 12 is connected to the pole 6 and an input / output unit of the storage means. Since the point positioning means and the read / write head 12 are electrically connected to each other via the position information input / output means such as the input / output device 13, the surveying device 1 is configured. When the point positioning means in the state where the pole 6 is fitted in 3s is caused to detect the current position of the point positioning means, the detected position data DAT1
The location information such as is the location information I of the location where the survey pile was placed.
It corresponds to position information such as NF. Further, since the point positioning means is electrically connected to the read / write head 12 via the position information input / output means, the position information detected by the point positioning means is transferred to the read / write head 12 by the position information input / output means. It can be transmitted as an electrical signal. Then, at this time (that is, the pole 6 is the pole housing portion 3
Since the read / write head 12 faces the input / output section of the storage means, the position of the read / write head 12 is changed from the input / output section to the information storage section of the storage means via the read / write head 12. It is possible to store information. That is, the operation of obtaining the position of the survey pile placing point by using the point positioning means in the state where the pole 6 is fitted in the pole accommodating portion 3s and the operation of storing the position in the storage means of the survey pile are performed at one time. It can be done easily. Similarly to this, in a state where the pole 6 is fitted in the pole housing portion 3s, the position information stored in the storage means can be read from the read / write head via the position information input / output means at any time. Therefore, even if it is not necessary to measure the position of the point where the survey pile is placed through a pole etc. and record the position obtained by the survey in a field notebook or recording device, Information can be recorded on the survey pile itself, and the recorded position information can be easily read out whenever necessary. That is, if the surveying device 1 of the present invention is used, the surveying work can be easily performed, and the position of the piled point can be easily detected at any time, which is very convenient. Therefore, it is possible to carry out surveying work efficiently and with few errors.

Further, in the surveying instrument 1 according to the present invention, when the point positioning means such as the GPS antenna 5 has a GPS antenna such as the receiving antenna 5a provided on the pole 6, the surveying instrument 1 is constructed, The point positioning means is a pole 6 fitted and supported in the pole accommodating portion 3s.
By causing the GPS antenna provided in the GPS antenna to receive the positioning signals S from a plurality of satellites, it is possible to detect the current position of the point positioning means in a form of obtaining the current position of the GPS antenna. Therefore, when obtaining the position of the point where the survey pile is placed as described above, this can be more easily performed by detecting the current position of the point positioning means using the surveying technology by GPS. . It is preferable that such a GPS antenna is provided at a position as high as possible in view of receiving the positioning signal S from the satellite. Therefore, the GPS antenna is provided on the pole 6 and used, but the pole 6 is used as a survey pile. The GPS antenna can be suitably held at a position having a predetermined height above the ground by the survey pile by being fitted and supported in the provided pole accommodating portion 3s. That is, it is possible to easily enter a preferable reception state, that is, a positioning state, without the trouble of holding the GPS antenna using a tripod or the like.

Further, according to the present invention, the surveying device 1 is used to drive a surveying pile such as the pile 2 at an arbitrary point such as a surveying point Pn, and the pole is accommodated in the pole accommodating portion 3s of the surveying pile. 6 is inserted into the spot, a spot positioning means such as the GPS device 5 is installed, the current position of the spot positioning means is detected by the spot positioning means, and the position data detected by the spot positioning means is detected. The position information of the DAT 1 or the like is set as the position information of the point information INF or the like of the place where the survey pile is set by the read / write head 12 through the position information input / output means of the input / output device 13 or the like. Stored in a storage means such as the storage element 7 of the survey pile,
Along with the position information of the point where the survey pile was placed, since it was configured to be held at that point, the placement of the survey pile and the detection of the position of the point where the survey pile was placed, The storage of the position information representing the position in the storage means is completed by a series of work operations. In addition, it is possible to easily detect the placement point of the survey pile directly at the time of placing the survey pile by the spot positioning means installed so that the pole 6 is fitted in the pole accommodating portion.
