Abstract

PROBLEM TO BE SOLVED: To easily and reliably monitor landslide and earthquake occurrence by providing an information transmitting stake to be driver into the ground with a communication part comprising a position recognizing apparatus by satellite communication and a transmitting apparatus to transmit the recognized position to a control center. SOLUTION: A case 3 to house a communication part 2 is formed in the head part 1b of the information transmitting stake 1, the upper part of the stake main boy 1a is screwed in the lower part of the case 3, and a cover 4 is screwed in the upper part. A GAS receiver 21 of the communication part 2 receives electric waves from a plurality of artificial stateliness 15 and a CPU 2 computes three-dimensional position, which is defined by the latitude, the longitude, and the altitude, of the information transmitting stake 1 at the moment based on the difference of the time taken to receive the electric waves by the GPS receiver 21. The three-dimensional movement of the information transmitting stake 1 can precisely be recognized by comparing the obtained three-dimensional position with the original position of the information transmitting stake 1 stored in a memory of the CPU 22 before an earthquake or landslide. The position information is transmitted from a transmission apparatus 24 to the control center 25 through the artificial satellites 15. In this manner, occurrence of an earthquake and landslide can easily and reliably be monitored.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an information transmission pile for transmitting position information of a pile driven into the ground and recognizing the position.

[0002]

2. Description of the Related Art In an area such as a mountainous area where the slope of a mountain is occupied by roads or houses, if an earthquake or a landslide occurs, there is a high possibility of being directly connected to a disaster. For this reason,
It is necessary to monitor the occurrence of an earthquake, a landslide, or the like. Generally, monitoring by a disaster prevention patrol by a disaster prevention observer or monitoring from the sky using an airplane or the like is performed.

[0003]

However, in a mountainous area or the like in a wide area, when traffic is inconvenient, there is a problem that a disaster prevention patrol by a disaster prevention observer is difficult and a sufficient monitoring cannot be performed. Also, it is difficult to constantly monitor from above using an airplane or the like.

An object of the present invention is to solve the above-mentioned problems and to obtain an information transmission pile capable of easily and reliably monitoring the occurrence of a landslide or an earthquake.

[0005]

In order to achieve the above object, an information transmission pile according to the present invention is provided with a communication unit on a pile driven into the ground, and the communication unit includes a position recognition device using satellite communication, A transmitting device that outputs the recognized position to an external management center.

According to the above configuration, when the position of the information transmission pile driven into the ground moves due to landslide, earthquake, or the like, the position is recognized by satellite communication by the communication unit provided on the pile, and the position information is managed. Since the data is output to the center, the occurrence of landslides, earthquakes, etc. can be monitored easily and reliably.

[0007]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 shows a side view of an information transmission pile according to one embodiment of the present invention. The information transmission pile 1 includes a pile main body 1a and a head 1b that are driven substantially vertically into the ground G. The head 1b has a case 3 in which the communication unit 2 is housed. The upper part of the pile body 1a is screwed into the lower part of the case 3, and the cover 4 is screwed into the upper part of the case 3. The case 3 is provided with a heat insulating material 5 on the entire inner surface of the case,
The communication unit 2 is housed in the heat insulating material 5. Communication unit 2
Is protected from outside by freezing, overheating and fire by being insulated from the outside by the heat insulating material 5. Also,
The pile main body 1a and the head 1b are buried deep, for example, about 1.5 m from the ground surface so that the communication section 2 is not affected as much as possible by external temperature changes and the like.

[0008] The information transmission pile 1 is further screwed into the cover 4 to support a GPS (General Purpose Satellite) antenna 6 substantially vertically, and a heat insulating material 5.
There is provided a ventilation device 8 such as a breather filled with silica gel for ventilating the inside and the ground to prevent dew condensation on the communication unit 2. A solar cell 9 serving as a power source of the communication unit 2 is fixed to a side portion of the support 7 in a direction and an angle at which the solar cell 9 can efficiently receive sunlight. The antenna code 6 a of the GPS antenna 6 and the wiring code 9 a of the solar cell 9 are wired in the support 7. The GPS antenna 6, the solar cell 9, and a part of the ventilation device 8 for ventilation are exposed from the ground surface, and are covered with a transparent dome-shaped cover 10 such as plastic that transmits radio waves. The cover 10 is fixed to the ground G by a retaining pile 12.

As shown in FIG. 2, the communication unit 2 includes a position recognition device 23 including a GPS receiver 21 and a CPU 22, and a transmission device 24. The communication unit 2 operates using the above-described solar cell as a power supply.

The GPS receiver 21 receives radio waves transmitted from a plurality of satellites 15, and the CPU 22 calculates information from the difference in time until the radio waves output from each satellite 15 reaches the receiver 21, and transmits information. The current “latitude”, “longitude”,
Calculate the three-dimensional position of "altitude". The original position of the information transmission pile 1 before the occurrence of the earthquake or landslide is stored in the memory of the CPU 22 in advance, and compared with this original position, the three-dimensional movement of the information transmission pile 1 after the occurrence of the earthquake or the landslide. Can be accurately recognized. This position information is output from the transmitting device 24 to the management center 25 via the satellite 15.

In this way, when the information transmission pile 1 moves from the original position due to an earthquake or landslide, the position is recognized by satellite communication by the communication unit 2 provided in the pile 1 and the position information is output to the management center 25. Therefore, an area where an earthquake or landslide has occurred can be accurately specified, and the occurrence of the earthquake or landslide can be easily and reliably monitored.

In this embodiment, the position information is output from the transmitting device 24 to the management center 25 via the satellite 15. If it is inside, the location information may be output to the transmission device 24 using a mobile phone.

In this embodiment, the movement of the information transmission pile 1 due to a landslide or an earthquake is recognized. However, if the information transmission pile 1 is intentionally pulled out of the ground and stolen, the occurrence of the theft is also recognized. can do.

[0014]

According to the present invention, when the position of the information transmission pile driven into the ground moves due to landslide, earthquake, or the like, the position is recognized by satellite communication by the communication unit provided on the pile, and the position information is obtained. Since the information is output to the management center, the occurrence of landslides and earthquakes can be easily and reliably monitored.
