Abstract

PROBLEM TO BE SOLVED: To provide a mountain stream area surveying tag system which lightens the work load on a person surveying and improves the survey accuracy at a survey point by simplifying the searching work for a survey tag to determine the position of the surveying point in a mountain stream area. SOLUTION: A modem modulates a searching position code inputted through a keyboard 10b of a searching unit 2 to a searching signal, which is then wirelessly transmitted by a transmitter-receiver. A transmitter-receiver in a surveying tag 1 receives the searching signal transmitted from the searching unit 2, and a modem demodulates this signal to a searching position code which is then compared with a true point code stored in a true position code memory. When both codes are identified, a high brightness lamp 5 blinks on the tag 1, together with a large volume sound produced by a powerful sound buzzer 6. If a person surveying recognizes both the blinking of the lamp and the buzzer sound, he can recognize the installed location of the tag 1 to determine a surveying point.

Description

Detailed Description of the Invention

[0001]

TECHNICAL FIELD The present invention relates to a mountain stream survey tag system including a search device for searching a survey tag used for determining the position of a survey point in a mountain stream.

[0002]

2. Description of the Related Art Conventionally, an organization that manages a river confirms the secular change of the river and prepares materials for river measures. In the work of confirming the secular change of rivers, the river topography is surveyed approximately every 1 to 3 years, and a river cross section is created based on the survey data, and the secular change of the river topography is judged from the river cross section. ing. In the surveying work to create the river cross section, the kilometer post (surveying tag) that is the reference point (base point) of the surveying point is searched and confirmed, and the surveying point determined based on the kilometer post is measured. Survey data is obtained.

Here, the kilopost is a distance marker such as a white pile or a tack-shaped marker (hereinafter referred to as a "tack-shaped marker") installed on the left bank and the right bank of the riverbed, and along the river basin. It is installed from the downstream side to the upstream side at intervals of about 200 m. Specifically, rod-shaped white stakes are installed at surveying points in the basin where the riverbed is relatively flat, and it is difficult to install white stakes in the basin where the riverbank is a steep cliff wall. Tack-shaped markers are installed instead of piles.

[0004]

However, since the above-described surveying work is performed at long intervals of about one to three years, there is a possibility that the topography and landscape of the river basin may change during that period. Especially in mountainous river basins in the upper reaches of rivers, the effects of wind, rain, and snow are unimaginable, and as a result,
The river may increase and a large amount of sediment may flow out. For this reason, there is a problem that in the mountain stream, the kiloposts such as white stakes are buried in the collapsed trees and runoff and the location is unknown. If the location of a kilopost is unknown in this way, it is not possible to determine the exact surveying point that is being surveyed every year.Therefore, the surveying work must be performed with the surveying point unclear, and the surveying data will be inaccurate. Therefore, there was a problem that the reliability of the river cross section was reduced.

Further, even if the river topography has not changed significantly, if the kilometer posts such as white piles are covered with the surrounding vegetation, the surveyor must enter into them and search for the kilometer posts. There is a problem that it requires a lot of labor. Moreover, since the tack-shaped markers installed on the cliff walls of mountain mountain rivers are much smaller than the white piles, they are harder to find than the white piles. For this reason, the surveyor may climb the cliff wall to search for and check the tack-shaped marker, and in such a case, there is a risk of accidentally falling from the cliff wall, and much labor and cost are required. There was a problem that it was necessary.

The present invention has been made to solve the above-mentioned problems, and simplifies the work of searching for a surveying tag for determining the position of a surveying point in a mountain stream and reduces the work load on the surveyor. It is an object of the present invention to provide a mountain stream stream survey tag system that can reduce the amount of noise and further improve the survey accuracy at the survey point.

Next, the processing executed by the surveying tag 1, the searcher 2, and the portable PC 40 configured as described above, and the surveying method using these devices 1, 2, 40 will be described. The processing in the survey tag 1 described below is executed by the control program 12a described above, and the processing in the searcher 2 is executed by the control program 22a described above.

First, the surveying device 2 searches for surveying tags 1 and 1 installed at a desired surveying point S among a plurality of surveying points S set at intervals of about 200 m in the river K. In the search step of the survey tag 1, first, when the keyboard 10b of the searcher 2 is operated to input the search position code, the search position code is temporarily stored and held in the RAM 23. After that, when the confirmation button 10a is pressed, the search position code is modulated into a search signal by the modem 28, and this search signal is wirelessly transmitted from the transceiver 27 through the antenna 8 for about 2 seconds.

If the survey tag 1 corresponding to the transmitted search signal (that is, the search position code) is not present in the vicinity of the searcher 2, the incoming lamp 9 of the searcher 2 does not light up and the incoming buzzer 29 does not ring. . In this case, the confirmation button 1 is pressed until the incoming lamp 9 and the incoming buzzer 29 of the searcher 2 are activated.
While pressing 0a several times, the search signal is wirelessly transmitted, and the peripheral area is circulated. On the other hand, in the surveying tag 1, the intermittent timing reception operation is executed, and the transceiver 1 of this embodiment
In No. 7, the receiving operation is executed for about 20 milliseconds at intervals of about 2 seconds.

If the surveying tag 1 is located in the vicinity of the searcher 2, the search signal transmitted from the searcher 2 is transmitted to the antenna 3 during the receiving operation of the transceiver 17 of the surveying tag 1 for about 20 milliseconds.
It is received via a. The received search signal is demodulated into a search position code by the modem 18 of the survey tag 1,
The control program 12a executed on the CPU 11 compares the actual position code stored in the actual position code memory 14a. When the real point code stored in the real position code memory 14a does not correspond to the search position code, the survey tag 1 does not perform the subsequent processing, and the intermittent timing by the transmitter / receiver 17 until the search signal is received again. The receiving operation is continued.

On the other hand, when the real point code stored in the real position code memory 14a corresponds to the search position code, that is, the surveying tag 1 which is the search target by the searcher 2 receives the search signal. In that case, in the survey tag 1,
The control program 12a activates the high-intensity lamp 5 and the strong sound buzzer 6 and wirelessly transmits a response signal to the searcher 2. When the high-intensity lamp 5 and the strong buzzer 6 are activated, the high-intensity lamp 5 flashes and emits light,
Since a loud buzzer sound is generated from the strong buzzer 6,
If the blinking light emission and the buzzer sound are confirmed by the surveyor, the survey location S can be confirmed by confirming the installation position of the survey tag 1.

Further, in the transmission of the response signal by the surveying tag 1, the real position code (ID code and real point code) stored in the real position code memory 14a is modulated into a response signal by the modem 18, and the response signal is generated. Transceiver 1
The data is wirelessly transmitted from 7 to the searcher 2 via the antenna 3a. The transmitted response signal is received by the transmitter / receiver 27 via the antenna 8 of the searcher 2, demodulated by the modem 28 into an actual position code, and written and stored in the position code holding memory 24a.

Further, in the searcher 2 which has received the response signal,
The operation of the incoming call lamp 9 and the incoming call buzzer 29 is started by the control program 22a, the incoming call lamp 9 is turned on, and a buzzer sound is generated from the incoming call buzzer 29. Therefore, a surveyor having the searcher 2 can recognize that the surveying tag 1 is installed in the vicinity thereof even if the blinking light emission and the buzzer sound from the surveying tag 1 to be searched cannot be confirmed. it can.

The survey tags 1, 1 installed on the right bank R and the left bank L of the survey point S by the flashing light emission of the high-intensity lamp 5 and the loud buzzer sound from the strong buzzer 6 described above, respectively.
If the installation position of is confirmed, the survey point S can be determined. Here, the portable PC 40 is connected to the PC interface 30 of the searcher 2 via the cable 31. When the power of the portable PC 40 is turned on and the survey data editing software 41b is activated, the searcher 2 that has detected the activation of the software 41b causes the control program 22a to move the actual position stored in the position code holding memory 24a. Transfer the code to the portable PC 40.

The transferred real position code is stored in the portable PC 4
0 is analyzed by the survey data editing software 41b, and the survey data (see FIG. 5) at the survey point S corresponding to the actual position code is analyzed by the survey data editing software 41b.
42 is displayed. By the way, when the visibility of the surveying point S is poor, the surveying tags 1 and 1 respectively installed on both banks R and L of the river K may be installed at positions outside the surveying point S.

In such a case, the surveying point S cannot be determined only by confirming the installation positions of the surveying tags 1 and 1. Therefore, in such a case, as shown in FIGS. 6B and 6C, the peripheral map data 62 and the peripheral photograph data 63 of the survey point S displayed on the LCD 42 of the portable PC 40, and the survey tag 1 are displayed. , 1 can be easily determined by comparing with the landscape around the position where 1 is actually installed. Moreover, portable PC
Since the power of the 40 is to be turned on at the time when the installation positions of the survey tags 1 and 1 are confirmed, it is not necessary to carry the portable PC 40 in a constantly operating state, and the burden on the surveyor during patrol is reduced. be able to.

On the other hand, as described above, the survey tags 1, 1
When the surveying point S is determined based on the survey line S, as shown in FIG. Is set. When the survey points P1 to P8 are set, a surveying instrument (not shown) is installed at the surveying point S, and the surveyor measures the respective surveying points P1 to P8. Based on this newly measured measurement data,
The survey data stored in the survey database 41a is updated by the survey data editing software 52 of the portable PC 40.

When the measurement process of one survey point S is completed, the above-mentioned confirmation data is created by the survey data editing software 52. This confirmation data is for cable 31
And transmitted to the searcher 2 via the PC interface 30 and modulated by the modem 28 of the searcher 2. The modulated confirmation data is sent to the survey tag 1 corresponding to the actual position code stored in the position code holding memory 24a by the transceiver 27, that is, the survey tag 1 installed at the survey point S where the survey process is completed. It is wirelessly transmitted via the antenna 8.

The transmitted confirmation data is received by the transceiver 17 via the antenna 3a of the survey tag 1, demodulated by the modem 18, and stored in the confirmation data memory 14b of the survey tag 1. In this way, when the confirmation data is stored in the survey tags 1 and 1 installed on both banks R and L of the survey point S, the survey work at the survey point S is completed.

The present invention has been described above based on the embodiments, but the present invention is not limited to the above embodiments, and various improvements and modifications can be made without departing from the spirit of the present invention. Can be easily guessed.

In the present embodiment, the surveying tag 1 which has received the search signal uses the search position code and actual position code memory 14a.
The high-intensity lamp 5 and the high-pitched sound buzzer 6 were immediately actuated when they correspond to the real point code stored in the above. It is not something that can be done.

For example, when the search position code and the actual position code correspond to each other, first, the response signal from the surveying tag 1 is transmitted, and then the confirmation button 10a is pressed by the searcher 2 which has received the response signal. It is also possible to transmit a signal indicating the fact to the surveying tag 1 and activate the above-mentioned units 5 and 6 when the signal is received by the surveying tag 1.

Further, in the present embodiment, the explanation has been given for the mountain stream as the survey point S where the survey tag 1 is installed.
The surveying point where the surveying tag 1 is installed is not limited to the mountain stream region which is the upstream region of the river K, and may be the downstream region of the river K.

According to the mountain stream geodetic survey tag system of the first aspect, when the survey tag receives the search signal from the search device by the search signal receiving means, the position notifying means emits light or voice. Since it will inform you of the installation position, if you use these light emission or voice as a clue,
Even if the terrain of the mountain stream changes with age, the survey tag can be easily found. Moreover,
Since the search device wirelessly transmits the search signal for operating the position notification means of the survey tag by the search signal transmitting means, even if the surveyor who has the search device is far from the installation position of the survey tag, There is an effect that the tag can be operated remotely and the position notification means can be operated reliably.

Therefore, the surveyor does not need to walk around the surveying tag to find the surveying point or climb the cliff wall to search for the surveying point in an area where walking is difficult, such as a mountain stream. Therefore, there is an effect that the work load on the surveyor can be reduced accordingly. Moreover, even if a long time has passed since the last survey, the installation position of the survey tag will not be unknown, so the survey point can be accurately determined and the reliability of survey data can be improved. There is an effect that can be.

According to the mountain stream geodetic survey tag system of claim 2, in addition to the effect of the mountain stream geodetic survey tag system of claim 1, the survey tag is analyzed from the search signal by the code comparison means. The search position code is compared with the actual position code stored in the first storage means, and when the two codes correspond to each other, the position notification means notifies the installation position, while when the two codes do not correspond to each other. The position notification means does not notify.

As a result, since only the surveying tag which is the search target by the surveyor notifies the position by light emission or voice, the surveying tag outside the search target does not execute the reporting operation, and the desired surveying tag can be displayed. It has the effect that it can be discovered accurately. Moreover, since the survey tag that is not the search target does not need to emit light or generate sound, there is an effect that power consumption can be suppressed by suppressing power consumption due to light emission or sound generation.

According to the mountain stream geodetic survey tag system of the third aspect, in addition to the effect of the mountain stream geodetic survey tag system of the second aspect, the survey tag uses the search position code and the actual position by the code comparison means. When it is determined that the codes correspond to each other, the response signal transmitting means wirelessly transmits the response signal based on the actual position code to the search device. On the other hand, in the search device, the response signal receiving means receives the response signal from the survey tag, analyzes the actual position code of the survey tag from the response signal, and stores it in the second storage means. Further, the stored real position code is transferred to the computer device by the transfer means.

Upon receipt of the transfer of the actual position code, in the computer device, the survey data searching means reads out the survey data relating to the survey point corresponding to the actual position code from the survey data storage means and displays the survey data. Displayed on the means. Therefore, the surveyed data on the surveyed point where the surveyed tag found is displayed without the surveyor having to operate the computer one by one, so that the surveyed data etc. of the previous survey can be easily checked on the spot. be able to.

By the way, when the visibility of the surveying point is poor, the surveying tag may be installed at a position outside the surveying point. In such a case, an accurate surveying point cannot be determined only by confirming the installation position of the surveying tag.
Therefore, in such a case, based on the survey data displayed by the display means of the computer device (for example, map data or photograph data around the survey point), the survey data and the landscape around the installation position of the survey tag are obtained. By comparing them, there is an effect that an accurate surveying point can be easily determined.

According to the mountain stream geodetic survey tag system of the fourth aspect, in addition to the effect of the mountain stream geodetic survey tag system of the third aspect, the survey data displayed by the display means of the computer device is the survey point. Is changed (updated) by the survey data changing means on the basis of the result of the measurement and stored in the survey data storage means. When the survey data is changed in this way, in the search device, the confirmation data indicating that the survey data has been changed is associated with the actual position code stored in the second storage unit by the confirmation data transmitting unit. It can be wirelessly transmitted to the survey tag.

On the other hand, the surveying tag that received the confirmation data
The confirmation data can be stored in the third storage means. Therefore, at the time of carrying out the next survey work, by checking the confirmation data stored in the third storage means, whether the previous survey was accurately carried out at the survey point where the survey tag is installed. There is an effect that it can be confirmed whether or not. Moreover, if the update date and time of the survey data or the name of the person in charge of the survey is used as the confirmation data, it can be utilized as reference data in the next survey.

According to the mountain stream geodetic survey tag system of the fifth aspect, in addition to the effect of the mountain stream geodetic survey tag system of the third or fourth aspect, the search device is configured to transmit the response signal from the survey tag by the response signal receiving means. When the wirelessly transmitted response signal is received, the response signal reception / informing means notifies that fact, so the surveyor can recognize that the surveying tag to be searched is installed in the vicinity of the search device. Therefore, there is an effect that the search range can be narrowed down before the light emission from the survey tag or the confirmation of the sound.

According to the mountain stream geodetic survey tag system of the sixth aspect, in addition to the effect of the mountain stream geodetic survey tag system according to any one of the first to fifth aspects, the power source of the survey tag is a solar cell. It is possible to supply power to each part of the survey tag by power generation by. Therefore, it is not necessary to install a power transmission line for supplying power to the survey tag, and it is not necessary to periodically replace the battery for the power source of the survey tag, which reduces equipment costs and maintenance costs. There is an effect that can be done.
