Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an installation position information indicator, an installation position information indicator device, and an installation position information indicator which are suitable for indicating the position of a land or a road, various information about a site, and the like. Pile and installation location information marking foundation stone unit.

[0002]

2. Description of the Related Art Conventionally, an installation position information indicator for indicating installation position information (for example, the position of a land or a road, various information about a site, etc.) that is information related to the installation position has been used. Specific examples of the installation position information indicator include a position indicating pile and a surveying pile. In other words, in order to specify points for surveying, construction, etc., and reference points for forming the national axis, etc., piles etc. are driven into those points, and those points It was done so as to clearly indicate the position. Further, when conducting a land ownership survey or the like, a surveying pile as disclosed in, for example, Japanese Utility Model Laid-Open No. 2-118815 is used as a position indicating member. This survey pile is driven into the ground, and a cap that is exposed to the ground is attached to the head of the pile body that is in the shape of an elongated rod, and the land number and the distance from the reference point of the land on the outer surface of this cap. The marking plate with the information of is attached with nails. Further, conventionally, a foundation stone on which a date when the construction of the building was started is engraved is installed in a building such as a building for the purpose of being a monument or an ornament. However, recently, not only the date on which the foundation stone was started, but also the three-dimensional position (ie, latitude,
It has been proposed that the longitude and altitude) or the name of the owner of the site where the foundation stone is installed be stamped and recorded so that the foundation stone also records information on the site where the foundation stone is installed. Because the information about the site is recorded and marked on the foundation stone, the buildings are destroyed by the earthquake or war, and the real owner's correspondence to each site or the property owners own each property. Even if it becomes difficult to visually discriminate the three-dimensional position or range of the site, the site is searched for the foundation stone and the information recorded on the foundation stone for the site. This is because by reading, it is possible to determine the correspondence of the true owner to each site, or the three-dimensional position and range of the site owned by each site owner. Such a recently proposed foundation stone is an example of the above-mentioned installation position information indicator because it indicates information about the site where the foundation stone is installed.

[0003]

However, since all the conventional position indicating piles and the like are formed in the same shape, the position of the point where the piles are struck is only seen by looking at the piles. It is not possible to recognize the installation position information such as pile information such as the construction purpose, etc. (that is, the position, purpose, etc. of the pile must be recognized one by one with reference to the topographic map or the survey map already created. It did not happen.) Further, according to the survey pile as disclosed in Japanese Utility Model Laid-Open No. 2-118815, if the pile head is filled with fallen leaves or snow, the information attached to the marking plate cannot be confirmed. Further, in the conventionally-established foundation stone, when a building or the like is destroyed by an earthquake or a war, a rubble due to the destruction is deposited on the premises, and an obstacle such as the rubble is recently proposed. Since the foundation stone is covered up, even if the foundation stone is searched for, the rubble above the foundation stone must be removed in order to read the engraved record of the foundation stone. Therefore, the engraved record of the foundation stone is read. It is difficult.

In view of the above circumstances, the present invention has an installation position information indicating device, an installation position information indicating device, an installation position information indicating pile, and an installation position information indicating fixed stone capable of easily confirming the installation position information. The purpose is to provide a unit.

The three-dimensional position such as height is accurately grasped by conducting surveys in advance. Then, at the reference points PT, in order to clearly indicate the position of the reference points PT, the driving piles 1 as the installation position information marking piles are driven. As shown in FIG. 1 and FIG.
The pile main body 2 has a pile main body 2 as an installation main body formed of a material such as plastic that can transmit magnetism.
Has a tapered tip. Therefore, at the lower part of the pile body 2 in FIG. 2, the pile impact point indicating portion 11 is aligned with the axial center TL1 of the pile body 2 extending vertically in FIG.

It is installed in the form cast in 2. And the pile body 2
Inside, the lid mounting hole 12 is formed so as to open toward the upper side of the pile main body 2 (the surface opposite to the pile striking point indicating portion 11).

Therefore, of the periphery of the pile main body 2, the pile main body 2
As shown in FIGS. 1 and 2, a side surface 6 that is embedded in the ground 62 and is in contact with the ground 62 is formed on the lower side of the ground.

Further, in the lid mounting hole 12 of the pile main body 2,
As shown in FIGS. 1 and 2, a lid 3 is attached. That is, the lid 3 is provided with a pillar portion 3f, and the lid 3 can open and close the lid mounting hole 12 formed in the pile body 2 by the pillar portion 3f. The length of the pillar portion 3f is shorter than the depth of the lid mounting hole 12. In addition, a hub portion 3e, which is a disc-shaped display portion, is integrally provided with the pillar portion 3f on the upper portion of the lid 3, and the hub portion 3e has the same size as the upper surface of the pile body 2. Is formed in. Then, on the upper surface of the hub portion 3e,
As shown in FIG. 1, two center lines 13a and 13b indicating the center of the hub portion 3e are written in such a manner that an intersection point XP of the center lines 13a and 13b is formed at the center of the upper surface of the hub portion 3e.

It is stored and stored in the form of a circle. The magnetic pattern MP is set in a form corresponding to a predetermined magnetic code KD, and the magnetic code KD is used for the pile information INF (that is, the driving position and the driving purpose of the driving pile 1). ) Is converted into a plurality of numerical values corresponding to the pile information INF and is set. Therefore, even if the pile information INF is converted into a magnetic code KD having an arbitrary numerical value, one pile information INF has one magnetic code K.
If D is set so as to correspond to one magnetic pattern MP, one magnetic code KD (that is, pile information INF) always corresponds, and a plurality of magnetic codes KD (that is, multiple pile information INF). ) Does not correspond.

The space between the pile body 2 and the storage element 5 in the element storage space 12a may be filled with a filling material such as resin (not shown).

Then, the pile information I stored in the storage element 5
The NF can be easily read and decoded by the information reading device 7 as a reading device that can read the magnetic pattern MP of the plate 23. As shown in FIG. 1, the information reading device 7 that constitutes the installation position information marking device together with the driving pile 1 has a main control unit 31, and the main control unit 31 is provided with a bus wire 31a.

2 connected to both.

Since the driving pile 1 and the information reading device 7 are configured as described above, the driving pile 1 is installed at each reference point PT as follows. First, the lid 3 is attached to the pile body 2. Then, the pillar portion 3f of the lid 3 is inserted into the lid mounting hole 12 provided in the pile main body 2,
The hub portion 3e of the lid 3 is attached to the upper surface of the pile main body 2 (pile driving point indicating portion 1
It is attached so as to cover the surface opposite to 1). So lid 3
2 is adjusted so that the pile striking point indicating portion 11 is in contact with the reference point PT, and the pile body 2 is straightened as shown by the chain double-dashed line in FIG. It is driven vertically downward (direction of arrow F in FIG. 2) and
As shown by the solid line, the ground 62 is installed so as to vertically penetrate. Then, as shown in FIG. 2, the pile main body 2 with the lid 3 attached thereto has the pile impact point indicating portion 11, the intersection point XP, and the reference point PT, which are the axis T of the pile main body 2 extending in the vertical direction.
It is vertically mounted so as to match L1.

While the pile main body 2 with the lid 3 attached thereto is vertically mounted at each reference point PT, each pile information INF (INF1 to INF1 to INF1 to INF1 to INF1 to A predetermined magnetic pattern MP (MP1 to MP4) corresponding to INF4) is applied to the groove 21s and the magnetostrictive strip 22 connected to the plate 23.
Each pile information INF (I
Magnetization work for storing and storing NF1 to INF4) is performed. The magnetizing work may be performed at the construction site 61, a factory, or the like.

When the magnetizing work for magnetizing the storage elements 5 to the predetermined magnetic patterns MP corresponding to the respective pile information INF is completed, the storage elements 5 respectively magnetized to the predetermined magnetic patterns MP are set to the predetermined pile information. INF (INF1 to I
Each reference point PT (PT1 to display NF4)
To PT4, etc.) are respectively stored in the element storage space 12a of the pile body 2 of each driving pile 1. That is, in the driving pile 1, as described above, by closing and opening the upper part of the lid mounting hole 12 provided in the pile body 2, the element storage space 12a can be opened and closed with respect to the outside. The lid 3 is provided to obtain the element storage space 12a in which the storage element 5 can be easily stored only by mounting the lid 3 in the lid mounting hole 12 or removing the lid 3 from the lid mounting hole 12. Can be opened and closed. Therefore, when the storage element 5 is stored in the driving pile 1, the lid 3 mounted in the lid mounting hole 12 of the pile body 2 is removed from the pile body 2 to open the lid mounting hole 12, and thus opened. The storage element 5 in the lid mounting hole 12
Just insert the lid, and attach the lid 3 to the lid attachment hole 12 again,
The storage element 5 can be easily stored in the element storage space 12a. In this way, each reference point PT (PT1 to P
Each of the storage elements 5 magnetized in the magnetic pattern MP (MP1 to MP4) corresponding to the predetermined pile information INF is stored in the element storage space 12a of the pile main body 2 of each of the driving piles 1 driven in (T4 etc.). By doing so, the driving position (three-dimensional position of each reference point PT) and the driving position of each driving pile 1 driven at each reference point PT (PT1 to PT4, etc.) Pile information INF (I
NF1 to INF4) can be stored.

On the other hand, the pile information INF stored in the driving pile 1 driven at each reference point PT is read and decoded by the information reading device 7 as follows, and the information is easily read. The pile information INF can be recognized. First,
An operator (not shown) positions the transmission / reception antenna 39 of the information reading device 7 in the vicinity of the driving pile 1, and then inputs a command to start the reading work via the input unit 32 of the information reading device 7. The input command is transmitted to the main control unit 31 via the bus line 31a, and the main control unit 31 receives the command to start the reading work and causes the magnetic field generation control unit 36 to generate a magnetic field. The resonance detector 42 is caused to detect resonance. That is, the magnetic field generation controller 36 controls the frequencies HZ1 and H
, ACZn of a plurality of frequencies HZ such as ZZn, ..., HZn, in order of frequency HZ1, HZ2 ,.
It is generated intermittently at a predetermined interval via the transmitting / receiving antenna 39. On the other hand, the plate 23 of the storage element 5 stored in the driving pile 1 has the predetermined pile information I as described above.
An alternating magnetic field having a predetermined frequency HZ corresponding to the magnetic pattern MP (that is, a frequency HZ forming the predetermined magnetic pattern MP), which is magnetized by the magnetic pattern MP corresponding to NF and is transmitted to the plate 23 by the transmitting / receiving antenna 39. Is generated, the magnetostrictive strip 22 resonates and vibrates with the alternating magnetic field of the frequency HZ corresponding to the magnetic pattern MP to generate a magnetic field due to the resonant vibration of the magnetostrictive strip 22. The magnetic field thus generated is applied to the pile main body 2 of the driving pile 1.
And, it passes through the lid 3 and reaches the transmission / reception antenna 39, and induces an induced voltage in the transmission / reception antenna 39 (that is, the coil). From the transmitting / receiving antenna 39, the specific frequency HZ
When an alternating magnetic field with a frequency other than 1, HZ2, ..., HZn is generated, the magnetostrictive strip 22 does not resonate and vibrate, so that the magnetostrictive strip 22 does not generate a magnetic field and an induced voltage is applied to the transmitting / receiving antenna 39. Does not happen.

Further, the resonance detecting section 42 detects the resonance of the magnetostrictive strip 22 of the storage element 5 housed in the driving pile 1, and the resonance is detected by the transmitting / receiving antenna 39 (that is, the coil). ) Is performed by detecting the induced voltage. That is, when the resonance detection unit 42 receives a command from the main control unit 31 to execute the detection of resonance, the resonance detection unit 42 detects the presence or absence of an induced voltage generated in the transmission / reception antenna 39 for each frequency HZ, and detects the presence / absence of an induced voltage in each frequency HZ. The main control unit 31 determines whether or not an induced voltage is generated in the AC magnetic field.
To the pattern detection unit 43 via. The pattern of the frequencies HZ1, HZ2, ..., HZn of the magnetic field generated via the transmission / reception antenna 39 is previously input to the pattern detection unit 43, and the pattern detection unit 43 determines whether or not the induced voltage is generated. By comparing the patterns with each other, the resonant frequency HZ of the magnetostrictive strip 22 can be detected. The detected frequency HZ is transmitted to the code conversion unit 40, and in the code conversion unit 40,
The frequency HZ is converted into a magnetic code KD including a predetermined electric signal. By the way, when the pile information INF is stored in the storage element 5, as described above, the pile information INF is converted into the magnetic code KD, and the plate 23 of the storage element 5 is formed by the magnetic pattern MP corresponding to the magnetic code KD. Were stored by magnetizing. Therefore, the frequency HZ at which the storage element 5 resonates is magnetized by the magnetic pattern MP corresponding to the magnetic code KD, and is a specific frequency corresponding to the magnetic bias pattern corresponding to the magnetic pattern MP. Since each frequency HZ corresponds to a predetermined magnetic code KD, the magnetic code KD when the frequency HZ transmitted to the code conversion unit 40 is converted into the magnetic code KD.
When the pile information INF is recorded in the storage element 5, it coincides with the magnetic code KD converted from the pile information INF.

The magnetic code KD detected by the code conversion section 40 is transmitted to the output section 33 via the main control section 31, and the output section 33 displays the magnetic code KD on the respective magnetic fields by a display or the like (not shown). Code KD
Is converted into a predetermined pile information INF corresponding to and displayed on the outside. By reading the pile information INF displayed in this way from a display or the like (not shown), the driving positions of the driving piles 1 driven to the respective reference points PT (PT1 to PT4, etc.) (tertiary point PT It is possible to easily recognize the original position) and the purpose of placing the driving pile 1 and the like.

Therefore, if the driving pile 1 is used, a predetermined pile information INF corresponding to the predetermined pile information INF is stored in the element storage space 12a of the pile body 2 of the driving pile 1 installed at each reference point PT of the construction site 61. Storage element 5 magnetized to the magnetic pattern MP of
Is stored and the magnetic pattern MP of the storage element 5 is read by the information reading device 7, the pile information INF stored and stored in the storage element 5 can be recognized. Then, the magnetic pattern MP of the storage element 5 is obtained by simply bringing the transmitting / receiving antenna 39 capable of generating an alternating magnetic field close to the pile body 2 in which the storage element 5 is housed in a state where the alternating magnetic field is generated, that is, Even if the transmitting / receiving antenna 39 is not in contact with the transmitting / receiving antenna 39, it can be detected from the outside of the pile main body 2, and therefore the pile information IN corresponding to the magnetic pattern MP
Even if the pile main body 2 and the transmitting / receiving antenna 39 are not in contact with each other, F can be easily read and recognized directly from the outside of the pile main body 2. Therefore, it is not necessary to compare the topographical map and the survey map already created with the pile main body 2 one by one. Further, if the driving pile 1 is used, the element storage space 12a formed by mounting the lid 3 on the pile body 2 removes the lid 3 from the pile body 2 or mounts it on the pile body 2. As a result, the storage element 5 stored in the element storage space 12a is removed from the element storage space 12a in a state where the pile main body 2 is driven into the ground 62. The pile information IN that is taken out and is stored and stored in the storage element 5 instead of the storage element 5.

Can be stored in the element storage space 12a. Therefore, according to the construction procedure, etc., the storage element 5 in which the pile information INF for the next work or the like is stored is stored in the pile main body 2 or the work content is changed due to the influence of weather conditions such as a typhoon. Then, the pile element INF stored in the pile main body 2 can be updated very easily, for example, by storing the storage element 5 in which the pile information INF such as the change content of the work is stored and stored in the pile main body 2.

In the present embodiment, the storage element 5 accommodated in the element accommodating space 12a of the pile body 2 is capable of vibrating in the alternating magnetic field when an alternating magnetic field having a predetermined frequency HZ is generated. INF is stored in the information reading device 7
Is the presence or absence of vibration of the storage element 5 at each frequency HZ, that is, the magnetic pattern MP is detected from the outside of the pile body 2 in a non-contact manner, and the pile information INF stored in the storage element 5 is detected.
However, the storage element 5 and the information reading device 7 are configured such that the pile information INF of the storage element 5 stored in the element storage space 12a can be recognized from the outside without contact. If so, it need not be limited to this. For example, the storage element 5 is constituted by a transmitter or the like which transmits a signal of a predetermined frequency at a predetermined interval in correspondence with a predetermined pile information INF, and the information reading device 7 is configured to output a signal emitted from the transmitter. It may be configured by a receiver or the like capable of receiving and analyzing the frequency HZ and transmission interval of the signal and the like so that the information reading device 7 recognizes the pile information INF emitted by the transmitter.

In addition to being stamped and recorded on a, the site tag YJH is also magnetically recorded on the recording tag 210. Recording tag 21
The site information YJH magnetically written at 0 can be read using the information reading device 225 as follows. That is, first, the transmitting / receiving antenna 233 of the information reading device 225 is located near the foundation stone unit 203. Next, an operator (not shown) inputs a command to start the reading work via the input unit 227 of the information reading device 225. The input command is transmitted to the main control unit 226 via the bus line 226a, and the main control unit 226
Upon receiving the command to start the reading operation, the magnetic field generation control unit 2
31 causes the magnetic field to be generated, and the resonance detection unit 235
To detect resonance. That is, the magnetic field generation controller 231
Generates an AC magnetic field at a predetermined frequency YH1 (that is, a frequency having the same value as the mechanical resonance frequency of the magnetostrictive strip 213) through the transmitting / receiving antenna 233 in a single stroke, and then at a predetermined time interval YT1. For a period of time, the generation of the magnetic field is stopped, and thereafter, an alternating magnetic field of a predetermined frequency YH2 (that is, a frequency twice the frequency YH1) is generated in a single stroke, and then the generation of the magnetic field is stopped for a time interval YT1. After that, the predetermined frequency YH3 (that is, the frequency YH3
After generating an alternating magnetic field having a frequency of three times H1) in a form of a blow, the generation of the magnetic field is stopped for a time interval YT2, and thereafter, the frequencies YH4, YH5, YH6 ,. A magnetic field having a harmonic overtone frequency) is generated in a single stroke with a time interval YT1.

On the other hand, the main body 205 of the foundation stone unit 203
The plate 215 of the recording tag 210 inserted in the
As described above, the magnetized plate 21 is magnetized in the magnetized pattern corresponding to the code YKD.
No. 5 gives a magnetic bias of a pattern corresponding to the code YKD to the magnetostrictive strip 213, so that the magnetostrictive strip 213 is in a state capable of causing a predetermined magnetomechanical coupling action to a magnetic field applied from the outside. Has become. That is, when the amorphous magnetostrictive strip 213 is in a predetermined magnetic field, each magnetic domain in the magnetostrictive strip 213 turns in a certain direction, and due to the turning of these magnetic domains, magnetic energy is accumulated in the magnetostrictive strip 213. To be done. In addition, each magnetic domain turns in a certain direction and the magnetostrictive strip 21
Magnetization of 3 causes magnetostriction of the magnetostrictive strip 213, and mechanical energy (elastic energy or the like) due to the distortion is stored in the magnetostrictive strip 213. In addition, the DC magnetic field and the AC magnetic field are applied to the magnetostrictive strip 2.
When added to 13, the magnetic flux acting on each magnetic domain of the magnetostrictive strip 213 increases or decreases. When the magnetic flux acting on each magnetic domain decreases, magnetic energy is released because each magnetic domain tries to return to their original orientation, and at the same time, the magnetization of the magnetostrictive strip 213 weakens, so that the magnetostriction is released.
Mechanical energy is released. Conversely, as the magnetic flux acting on the magnetic domains increases, more magnetic and mechanical energy is stored. The stored and released mechanical energy increases when the frequency of the alternating magnetic field applied to the magnetostrictive strip 213 coincides with the harmonic overtone frequency of the mechanical resonance frequency of the magnetostrictive strip 213, and decreases at other frequencies. . As described above, the magnetostrictive strip 213 emits magnetic energy, and mechanical energy is emitted in the form of magnetic energy to generate an AC magnetic field. The generated AC magnetic field is the frequency of the AC magnetic field applied to the magnetostrictive strip 213. Increases when it coincides with the overtone frequency of the mechanical resonance frequency of the magnetostrictive strip 213, and decreases at other frequencies. In the magneto-mechanical coupling action described above, the magnetostrictive strip 213 is applied to the plate 21.
It is known that this occurs remarkably when it is activated by receiving a magnetic bias from the magnetostrictive strip 2.
Which of the harmonic overtone frequencies of the mechanical resonance frequency of the magnetostrictive strip 213 generates the strong AC magnetic field depends on the pattern of the magnetic bias applied to the magnetostrictive strip 213 by the plate 215. That is, it corresponds to the magnetization pattern of the plate 215. Therefore, from the transmitting / receiving antenna 233 to the frequency Y
As described above, the magnetic fields H1, YH2, YH3, ...
3, these magnetic fields are sequentially applied, so that the magnetostrictive strip 213 causes the specific frequency YHn (one or more of the harmonic frequencies of the mechanical resonance frequency) corresponding to the pattern of the magnetic bias by the plate 215. When a magnetic field having a magnetic field of (1) is applied, resonance vibration occurs due to the magneto-mechanical coupling action, and when a magnetic field having a frequency other than the specific frequency YHn is applied, it hardly vibrates. Therefore, when a magnetic field having a specific frequency YHn is generated from the transmission / reception antenna 233, the magnetostrictive strip 213 resonates and vibrates, and the frequency Y
Immediately after the Hn magnetic field is generated from the transmission / reception antenna 233 in the form of a single blow, during a time interval YT1 in which no magnetic field is generated,
Since the magnetostrictive strip 213 continuously undergoes damped vibration, the damped vibration of the magnetostrictive strip 213 causes the recording tag 2 to move.
10 generates a magnetic field. The magnetic field generated by the damping vibration of the recording tag 210 passes through the main body 205 of the foundation stone unit 203 and reaches the transmission / reception antenna 233, causing an induction voltage in the transmission / reception antenna 233 (that is, the coil). Further, when a magnetic field having a frequency other than the specific frequency YHn is generated from the transmission / reception antenna 233, the magnetostrictive strip 213 hardly resonates and vibrates, so that the recording tag 210 does not generate a magnetic field and is guided to the transmission / reception antenna 233. No voltage is generated.

By the way, as described above, the main control section 226 receives the command to start the reading operation, causes the magnetic field generation control section 231 to perform the sweep generation of the magnetic field, and causes the resonance detection section 235 to detect the resonance. It is done. That is, the resonance detector 235 detects resonance. That is, the resonance detection unit 235 receives the command from the main control unit 226 to execute the detection of resonance, and accordingly, the main control unit 226 determines that
With the passage of time, with reference to the time when the command for generating the magnetic field sweep is transmitted to the magnetic field generation control unit 231, and accordingly, the time when the magnetic field generation control unit 231 generates one blow of the magnetic field of the predetermined frequency YH1 via the transmission / reception antenna 233. The presence or absence of an induced voltage generated in the transmission / reception antenna 233 is detected. When an induced voltage is generated in the transmission / reception antenna 233, since the magnetostrictive strip 213 resonates, the presence or absence of the detected induced voltage with the passage of time is detected by the magnetostrictive strip 213 with the passage of time. The resonance information YGH indicating the presence or absence of resonance is sequentially reported to the main control unit 226.

After the magnetic field generation control unit 231 performs the sweep generation of the magnetic field for a predetermined time and the resonance detection unit 235 detects the resonance for substantially the same time as the sweep generation, the main control unit 226 receives the received signal. The resonance information YGH is transmitted to the frequency detection unit 232. The frequency detection unit 232 includes magnetic field frequencies YH1, YH2, and YH of the magnetic fields generated by the magnetic field generation control unit 231 in the form of a single blow over time.
The pattern of 3, ... Is input in advance. Therefore, the frequency detecting unit 232 detects the resonance frequency YHn of the magnetostrictive strip 213 by comparing and comparing the resonance information YGH indicating the presence or absence of resonance of the magnetostrictive strip 213 with the passage of time with the pattern. It The detected frequency YHn is transmitted to the code conversion unit 230, and the code conversion unit 230 converts the frequency YHn into a code YKD including a predetermined electric signal. By the way, site information Y
When recording JH on the recording tag 210, as described above, the site information YJH is converted into the code YKD, the code YKD is converted into the magnetic head control signal YJS, and a magnetic pattern corresponding to the magnetic head control signal YJS is obtained. Magnetic recording was performed by magnetizing the plate 215 of the recording tag 210. Therefore, the frequency YH at which the recording tag 210 resonates
n is a specific frequency magnetized in a magnetization pattern corresponding to the magnetic head control signal YJS and corresponding to a magnetic bias pattern corresponding to the magnetic head control signal YJS. The frequency YHn corresponds to the magnetic head control signal YJS, and the magnetic head control signal YJS is the code YK.
Since it corresponds to D, the frequency YHn corresponds to the code YKD. That is, the code YKD when the frequency YHn transmitted to the code conversion unit 230 is converted into the code YKD matches the code YKD obtained by converting the site information YJH when the site information YJH is recorded in the recording tag 210. To do.

The code YKD detected by the code conversion section 230 is transmitted to the main control section 226, and the main control section 22.
6 transmits the code YKD to the output unit 229 and outputs it to the outside. The output unit 229 displays the code YKD by a numerical value or the like on a display or the like not shown. Since the displayed code YKD corresponds to the site information YJH recorded in the recording tag 210 as described above, the site information YJH, that is, the three-dimensional position of the residential site 1 is read by reading the code YKD. The start date and time, the owner name, etc. can be known.

The site information YJH can be read from the recording tag 210 described above not only when there is no obstacle on the marking surface 205a side of the foundation stone unit 203, but the foundation stone unit 203. Stamped surface 2

A magnetic field can be exchanged between the recording tags 210 located below the. In other words, the destruction of buildings (not shown),
Even if it becomes difficult to visually determine the correspondence of the true owner to each land due to the accumulation of the rubble 260, the site information YJH can be obtained from the record tag 210 of the foundation stone unit 203 installed. By reading, the correspondence of the true owner to each land can be easily determined. Further, the range of land owned by each owner can be easily determined by reading the site information YJH from the recording tag 210. Further, even if the obstacle existing on the engraved surface 205a side of the foundation stone unit 203 is other than the rubble 260 such as concrete or wood, the thickness of the obstacle from the ground does not exceed the predetermined thickness, and the obstacle If the object transmits electromagnetic waves (for example, a layer of volcanic ash from a volcanic eruption or a layer of earth and sand from a flood), the site from above the obstacle is treated in the same manner as the example of the rubble 260 described above. The information YJH can be read.

When the magnetic field is generated, the recording tag 210 in a state of being closely opposed to the magnetic head 223 is slid in the direction of arrow YA in FIG. 12 to perform magnetic recording in the same manner as the conventional magnetic recording method (note that the result of the magnetic recording is , The contents that were magnetically recorded in the previous recording work were erased and updated.)
