Description

  The present invention relates to an earthquake observation system and a seismometer.

  2. Description of the Related Art Conventionally, an earthquake observation system that observes an earthquake using a seismometer is known (for example, see Patent Document 1). When the seismometer determines that an earthquake has occurred, it records acceleration data of the seismic motion as a waveform file. The waveform file is collected through a communication line such as a telephone line or the Internet by a remote computer periodically or when an earthquake occurs. When collecting the waveform file, the remote computer performs automatic collection by a program in addition to collection by a user's manual operation.

In addition to the method of collecting waveform files by a remote computer as described above, there is also known a method in which acceleration data is always transmitted from a seismometer to a remote receiving computer and filed as a waveform file by the receiving computer. ing. According to this method, it is possible to observe vibrations constantly without using the seismometer to determine the occurrence of an earthquake.
There is also known a method in which a method of collecting a waveform file by a remote computer and a method of constantly receiving acceleration data by a remote computer are hybridized. In this method, acceleration data that is constantly transmitted from a seismometer is received by a remote computer at the remote location, and the waveform file is transferred if necessary by judging whether the waveform file is necessary from the received acceleration data. The waveform file requested to be transferred is transferred from the seismometer.

Japanese Patent No. 3963726

However, with the above method of collecting waveform files using a remote computer, if a large-scale earthquake occurs, the communication infrastructure may be damaged by the main shock or aftershock, making it difficult to collect waveform files. There was.
In addition, when the location of the computer is far from the location of the seismometer, it may not be possible to immediately know the occurrence of the earthquake, and the waveform file cannot always be collected at an appropriate timing.
In addition to acceleration data, the waveform file also contains information such as seismic intensity and SI (Spectrum Intensity) values that cannot be determined until after the earthquake. In addition, since the length of the earthquake motion is different for each earthquake, the file length of the generated waveform file is indefinite. Therefore, it is difficult to know the completion of waveform file generation from a remote computer, and usually when a change in the time stamp of the waveform file is monitored for a few seconds to confirm that there is no change, transfer is performed. There is a problem that a time lag occurs before the transfer is started.

  Also, with the above method of creating a waveform file on a remote computer, if the communication infrastructure fails during an earthquake disaster, the waveform file cannot be recorded in the seismometer, and the observation data is lost. There is a problem of end up.

Even in the hybrid method of the above two methods, it is difficult to know the completion of waveform file generation because only acceleration data is transmitted to a remote computer unless there is a waveform file transfer request. There is a problem that a time lag occurs before the transfer starts.
In addition, since the waveform file transferred from the seismometer is determined on the remote computer side, there is a problem that all waveform files cannot be collected or a waveform file that does not exist is required.

  Hereinafter, an earthquake observation system according to an embodiment of the present invention will be described in detail with reference to the drawings. However, the scope of the invention is not limited to the illustrated examples.

First, the configuration of the earthquake observation system 100 according to the present embodiment will be described with reference to FIG.
As shown in FIG. 1, the earthquake observation system 100 includes a server device 1 as a receiving device and a plurality of seismometers 2. In this earthquake observation system 100, the server device 1 and the seismometer 2 are connected to each other via a communication network N so as to be communicable with each other. The communication network N is specifically a telephone line network or the like such as the Internet or a telecommunication carrier.
In the example illustrated in FIG. 1, the configuration in which a plurality of seismometers 2 are connected to a single server device 1 is described as an example. However, the configuration is not limited thereto. For example, a single server device is provided. 1, one seismometer 2 may be connected to the network, or one seismometer 2 may be connected to the plurality of server devices 1 via the network.

The server device 1 is, for example, an information device such as a PC or WS (Work Station), and is installed in a remote place away from a plurality of seismometers 2 by a predetermined distance or more. Here, the predetermined distance is a distance that is far enough not to be affected by the earthquake when a large-scale earthquake occurs in the vicinity of the place where the seismometer 2 is installed.
As illustrated in FIG. 2, the server device 1 includes a control unit 11, an operation unit 12, a display unit 13, a storage unit 14, and a communication unit 15.

  The control unit 11 centrally controls the operation of the server device 1. Specifically, the control unit 11 is configured to include a CPU, a ROM, a RAM, and the like. The program data stored in the ROM or the storage unit 14 expanded in the work area of the RAM and the CPU cooperate with the CPU. The overall control of each part of the device 1 is performed.

  The operation unit 12 includes, for example, a character input key, a numeric input key, a keyboard having keys associated with various functions, a pointing device such as a mouse, and the like, and receives an operation input from a user to input the operation. A corresponding operation signal is output to the control unit 11.

  The display unit 13 includes, for example, a display such as a CRT (Cathode Ray Tube) or an LCD (Liquid Crystal Display), and displays an image based on the display control signal output from the control unit 11 on the display screen.

  The storage unit 14 includes, for example, a hard disk drive (HDD), a semiconductor memory, and the like, and stores data such as program data and various setting data so that the control unit 11 can read and write the data. The storage unit 14 stores the waveform file transferred from the seismometer 2. In addition to acceleration data, the waveform file includes information such as seismic intensity and SI value.

  The communication unit 15 is a communication interface having a communication IC (Integrated Circuit), a communication connector, and the like, and performs data communication via the communication network N using a predetermined communication protocol under the control of the control unit 11. For example, the communication unit 15 receives a waveform file transferred from the seismometer 2.

  As shown in FIG. 3, the seismometer 2 includes a control unit 21, a vibration detection unit 22, an AD conversion unit 23, a storage unit 24, and a communication unit 25.

  The control unit 21 centrally controls the operation of the seismometer 2. Specifically, the control unit 21 includes a CPU, a ROM, a RAM, and the like. The program data stored in the ROM or the storage unit 24 expanded in the RAM work area and the CPU cooperate with the earthquake. Centralized control of all 2 parts.

The vibration detection unit (vibration detection means) 22 detects vibration caused by an earthquake as an analog signal. The vibration detection unit 22 is constituted by, for example, a servo-type vibration detector, and returns the deviation from the neutral position of the pendulum provided therein to the neutral position by current amount control using the drive coil. The acceleration in each direction is detected by measuring the current flowing through the.
The AD converter 23 converts the analog signal detected by the vibration detector 22 into a digital signal. The digital signal subjected to AD conversion by the AD conversion unit 23 is output to the control unit 21. The control unit 21 generates a waveform file based on the digital signal output from the AD conversion unit 23 and causes the storage unit 24 to store the generated waveform file.

  The storage unit 24 includes, for example, an HDD, a semiconductor memory, and the like, and stores data such as program data and various setting data in a readable / writable manner from the control unit 21. The storage unit 14 stores the waveform file generated by the control unit 21 as storage means. The storage unit 14 registers the file name of the generated waveform file, and stores a transfer list for managing the list of waveform file transfers.

  The communication unit 25 is a communication interface having a communication IC, a communication connector, and the like, and performs data communication via the communication network N using a predetermined communication protocol under the control of the control unit 21. For example, the communication unit 25 transfers the waveform file generated by the control unit 21 to the server device 1 as a communication unit.

Next, operation | movement of the seismometer 2 of the earthquake observation system 100 which concerns on this embodiment is demonstrated with reference to FIGS.
First, the control unit 21 determines whether or not an occurrence of an earthquake has been detected (step S11). For example, the control unit 21 determines that the occurrence of an earthquake has been detected when the vibration detection unit 22 detects a vibration that is equal to or greater than a preset threshold value.
If it is determined that the occurrence of an earthquake has been detected (step S11: YES), the process proceeds to the next step S12.
On the other hand, when it determines with the occurrence of an earthquake not being detected (step S11: NO), the process of step S11 is repeated until the occurrence of an earthquake is detected.

Next, the control part 21 produces | generates the waveform file of the earthquake detected by step S11 (step S12). Specifically, the control unit 21 generates a waveform file based on the digital signal obtained by AD conversion of the analog signal detected by the vibration detection unit 22 by the AD conversion unit 23. The waveform file continues to be generated until a predetermined time elapses when the vibration detection unit 22 detects vibration less than a preset threshold. For example, in the example shown in FIG. 5, four waveform files F11 to F14 are generated by one earthquake.
That is, the control unit 21 functions as a generation unit that generates a waveform file based on the vibration detected by the vibration detection unit 22.

Next, the control unit 21 registers the file name of the waveform file generated in step S12 in the transfer list (step S13). The process of step S13 is performed at the same time as the generation of one waveform file is completed in step S12. For example, when the generation of the waveform file F11 is completed, the file name of the waveform file F11 is registered in the transfer list L1 (see FIG. 6A). A plurality of waveform files are usually generated in one earthquake, and the file name is registered each time a waveform file is generated. The transfer list may be stored in the storage unit 24 or stored in the RAM of the control unit 11.
That is, the control unit 21 functions as a registration unit that registers the waveform file generated by the generation unit in the transfer list.

Next, the control unit 21 sequentially transfers the oldest waveform file among the waveform files registered in the transfer list, that is, the waveform file with the oldest registered date and time to the server device 1 via the communication unit 25 (step S14). ). In the present embodiment, a plurality of waveform files cannot be transferred at the same time, and only one of the waveform files is transferred. For example, as shown in FIG. 5, when the generation of the waveform file F13 is completed during the transfer of the waveform file F12, the transfer of the waveform file F13 is performed after the transfer of the waveform file F12 is completed.
That is, the control unit 21 functions as a transfer unit that transfers the waveform files registered in the transfer list by the registration unit to the server apparatus 1 via the communication unit 25 in order from the waveform file with the oldest registered date and time.

Next, the control unit 21 deletes the file name of the waveform file transferred to the server device 1 in step S14 from the transfer list (step S15). The process in step S15 is performed at the same time as the transfer of the waveform file transferred in step S24 is completed.
That is, the control unit 21 functions as a deletion unit that deletes the waveform file transferred to the server device 1 by the transfer unit from the transfer list.

The above processing is repeated until the file names of all waveform files generated in step S12 are deleted from the transfer list.
Here, with reference to FIG. 5 and FIG. 6, the flow of the above processing will be specifically described by exemplifying a case where four waveform files F11 to F14 are generated by one earthquake.

  First, the waveform file F11 is generated at the timing when the occurrence of an earthquake is detected. When the generation of the waveform file F11 is completed (see FIG. 5A), the file name of the waveform file F11 is registered in the transfer list L1 (see FIG. 6A). Then, the waveform file F11 is transferred to the server device 1.

  Following the completion of the generation of the waveform file F11, the waveform file F12 is generated. In the example shown in FIG. 5, the transfer of the waveform file F11 is completed before the generation of the waveform file F12 is completed (see FIG. 5B). At the timing when the transfer of the waveform file F11 is completed, the file name of the waveform file F11 is deleted from the transfer list L1 (see FIG. 6B). Next, when the generation of the waveform file F12 is completed (see FIG. 5C), the file name of the waveform file F12 is registered in the transfer list L1 (see FIG. 6C). Then, the waveform file F12 is transferred to the server device 1.

  Following the completion of the generation of the waveform file F12, the waveform file F13 is generated. In the example shown in FIG. 5, the generation of the waveform file F13 is completed before the transfer of the waveform file F12 is completed (see FIG. 5D). At the timing when the generation of the waveform file F13 is completed, the file name of the waveform file F13 is registered in the transfer list L1 (see FIG. 6D). Next, when the transfer of the waveform file F12 is completed (see FIG. 5E), the file name of the waveform file F12 is deleted from the transfer list L1 (see FIG. 6E). At this time, the waveform file F13 registered in the transfer list L1 but not transferred is transferred to the server apparatus 1.

Following the completion of generation of the waveform file F13, a waveform file F14 is generated. In the example shown in FIG. 5, the generation of the waveform file F14 is completed before the transfer of the waveform file F13 is completed (see FIG. 5 (f)). At the timing when the generation of the waveform file F14 is completed, the file name of the waveform file F14 is registered in the transfer list L1 (see FIG. 6F). Next, when the transfer of the waveform file F13 is completed (see FIG. 5G), the file name of the waveform file F13 is deleted from the transfer list L1 (see FIG. 6G). At this time, the waveform file F14 registered in the transfer list L1 but not transferred is transferred to the server apparatus 1.
As described above, all the waveform files F11 to F14 generated in step S12 can be transferred.

As described above, the seismometer 2 of the earthquake observation system 100 according to the present embodiment includes the vibration detection unit (vibration detection unit 22) that detects vibration caused by the earthquake, and the waveform file based on the vibration detected by the vibration detection unit. Of the waveform file registered in the transfer list by the registration means (control unit 21), the registration means (control unit 21) for registering the waveform file generated by the generation means in the transfer list, In order from the oldest waveform file, the transfer means (control unit 21) for transferring to the receiving apparatus (server apparatus 1) via the communication means (communication section 25) and the waveform file transferred to the receiving apparatus by the transferring means Deleting means (control unit 21) for deleting from the transfer list.
Therefore, according to the seismic observation system 100 according to the present embodiment, the generated waveform file can be automatically transferred at the timing when the communication unit 25 becomes available, so that the waveform file transfer to the server device 1 can be performed. Certainty can be increased. In addition, since it is not necessary to provide waveform file collection software and waveform file generation software in the server apparatus 1, the server apparatus 1 can be realized without incurring the cost and labor involved in backing up the waveform file.

  As mentioned above, although concretely demonstrated based on embodiment which concerns on this invention, this invention is not limited to the said embodiment, It can change in the range which does not deviate from the summary.

(Modification)
For example, in the examples shown in FIGS. 7 to 9, the waveform file cannot be transferred completely due to a long-term power failure after the earthquake, and what has been recorded in the seismometer in the past, such as a situation where power has been restored, has not been transferred. The operation of the seismometer 2 when transferring a waveform file is illustrated. In addition, since the apparatus structure of a modification is the same as that of embodiment, the same code | symbol is attached | subjected and the detailed description is abbreviate | omitted.

Hereinafter, the operation of the seismometer 2 of the earthquake observation system 100 according to the modification will be described with reference to FIGS. Here, a case where a waveform file cannot be transferred completely due to a long-term power failure after the earthquake and power is restored after that will be described as an example.
First, the control part 21 registers the file name of the waveform file memorize | stored in the memory | storage part 24 at the untransfer list | wrist at the time of a power recovery from a power failure (step S21). The waveform file registered in the untransferred list is a waveform file generated within a predetermined time from the time of a power failure among the waveform files stored in the storage unit 24. Here, waveform files F21 and F22 are illustrated as waveform files generated within a predetermined time (see FIG. 8). The untransferred list is registered in order from the newly generated waveform file. For example, in the example shown in FIG. 8, since the waveform files F21 and F22 are generated in this order, the waveform files F22 and F21 are registered in the untransfer list L2 in this order (see FIG. 9A).
That is, the control unit 21 registers, as a registration unit, a waveform file generated within a predetermined time from the time of the power failure among the waveform files stored in the storage unit 24 at the time of power recovery from the power failure in the untransfer list.

Next, the control unit 21 determines whether or not an occurrence of an earthquake has been detected (step S22). Since the process of this step S22 is the same as the process of step S11 of FIG. 4 which shows the operation | movement of the seismometer 2 of embodiment, description is abbreviate | omitted.
Next, the control part 21 transfers to the server apparatus 1 via the communication part 25 in an order from the newest waveform file of the produced date / time among the waveform files registered in the untransferred list (step S23). For example, in the example shown in FIG. 8, first, a new waveform file F22 with the generated date and time is transferred to the server device 1.
That is, the control unit 21 causes the server device 1 to transfer the waveform files registered in the untransferred list by the registration unit to the server device 1 via the communication unit 25 in order from the newest waveform file with the generated date and time.

Next, the control part 21 produces | generates the waveform file of the earthquake detected by step S22 (step S24). The process of step S24 is started simultaneously with the process of step S23. For example, in the example shown in FIG. 8, two waveform files F23 and F24 are newly generated by one earthquake.
Next, the control unit 21 registers the file name of the waveform file generated in step S24 in the transfer list (step S25). For example, when the generation of the waveform file F23 is completed, the file name of the waveform file F23 is registered in the transfer list L3 (see FIG. 9B).

Next, the control part 21 transfers to the server apparatus 1 in an order from the waveform file with the highest priority among the waveform files registered in the transfer list or the non-transfer list (step S26). In the modification, the waveform file registered in the transfer list is transferred with priority over the waveform file registered in the non-transfer list. For example, as shown in FIG. 8, when the transfer of the waveform file F22 is completed and the generation of the waveform file F23 is completed simultaneously, the waveform file (waveform file F23) registered in the transfer list is stored. The data is transferred with priority over the waveform file (waveform file F21) registered in the untransferred list.
That is, the control unit 21 transfers the waveform file registered in the transfer list with priority over the waveform file registered in the non-transfer list as a transfer unit.

Next, the control unit 21 deletes the file name of the waveform file transferred to the server device 1 in step S26 from the transfer list or the untransferred list (step S27).
In other words, the control unit 21 deletes, from the untransfer list, the waveform file transferred to the server device 1 by the transfer unit from among the waveform files registered in the non-transfer list.

In the above processing, the file names of all waveform files registered in the untransferred list in step S21 are deleted from the untransferred list, and the file names of all waveform files generated in step S24 are deleted from the transfer list. It will be repeated until it is done.
Here, referring to FIG. 8 and FIG. 9, two waveform files F23 and F24 are generated by one more earthquake in a situation where the waveform file cannot be transferred completely due to a long-term power failure after the earthquake and power is restored after that. The flow of the above processing will be specifically described by exemplifying the case where it is generated.

  First, waveform files F21 and F22, which are waveform files generated within a predetermined time from the present, are registered in the untransferred list L2 at the timing of power recovery from a power failure (see FIG. 8A). Since the newly generated waveform files are registered in order in the untransferred list L2, the waveform files F22 and F21 are registered in this order (see FIG. 9A).

Next, generation of the waveform file F23 is started at the timing when the occurrence of the earthquake is detected. Simultaneously with the start of generation of the waveform file F23, the waveform file F22 having the highest priority in the untransferred list L2 is transferred to the server device 1.
In the example shown in FIG. 8, the generation completion of the waveform file F23 and the transfer completion of the waveform file F22 are simultaneously performed (see FIG. 8B). When the generation of the waveform file F23 is completed, the file name of the waveform file F23 is registered in the transfer list L3 (see FIG. 9B). When the transfer of the waveform file F22 is completed, the file name of the waveform file F22 is deleted from the untransferred list L2 (see FIG. 9B).

As described above, in the example shown in FIG. 8, the generation completion of the waveform file F23 and the transfer completion of the waveform file F22 are the same, so the waveform file F23 in the transfer list L3 and the untransferred list L2 All of the waveform files F21 are transferable. In the example shown in FIG. 8, the waveform file registered in the transfer list L3 (waveform file F23) is transferred with priority over the waveform file registered in the untransferred list L2 (waveform file F21). The file F23 is transferred to the server device 1.
At the same time as the transfer of the waveform file F23, that is, following the completion of the generation of the waveform file F23, the generation of the waveform file F24 is started.

  In the example shown in FIG. 8, the transfer of the waveform file F23 is completed before the generation of the waveform file F24 is completed (see FIG. 8C). At the timing when the transfer of the waveform file F23 is completed, the file name of the waveform file F23 is deleted from the transfer list L3 (see FIG. 9C). At the timing when the file name of the waveform file F23 is deleted, as shown in FIG. 9C, no waveform file is registered in the transfer list L3, and the waveform file F21 is registered in the untransferred list L2. ing. Accordingly, the waveform file F21 is transferred to the server device 1.

When the generation of the waveform file F24 is completed (see FIG. 8D), the file name of the waveform file F24 is registered in the transfer list L3 (see FIG. 9D). In the example shown in FIG. 8, the generation of the waveform file F24 is completed before the transfer of the waveform file F21 is completed. Next, when the transfer of the waveform file F21 is completed (see FIG. 8E), the file name of the waveform file F21 is deleted from the untransferred list L2 (see FIG. 9E). At the timing when the file name of the waveform file F21 is deleted, as shown in FIG. 9E, no waveform file is registered in the untransferred list L2, and the waveform file F24 is registered in the transfer list L3. ing. Therefore, the waveform file F24 is transferred to the server device 1.
As described above, all of the waveform files F23 and F24 registered in step S21 and the waveform files F23 and F24 generated in step S24 can be transferred.

As described above, according to the seismic observation system 100 according to the modified example, the earthquake observation system 100 further includes the storage unit (storage unit 24) that stores the waveform file generated by the generation unit. Of the waveform files stored in the storage means, the waveform file generated within a predetermined time from the time of the power failure is registered in the untransferred list, and the transfer means is generated among the waveform files registered in the untransferred list by the registering means. In order from the newest waveform file with the date and time transferred to the receiving device via the communication means, the deleting means transfers the waveform file transferred to the receiving device by the transferring means from among the waveform files registered in the untransferred list. Delete from.
Therefore, according to the seismic observation system 100 according to the modified example, the waveform file generated within a predetermined time can be automatically transferred, so that the waveform file generated before the occurrence of the earthquake can be backed up. In addition, the waveform files generated before the occurrence of the earthquake are transferred in order from the shortest elapsed time since the completion of the generation, so that the waveform file having the highest necessity can be backed up preferentially.

Moreover, according to the earthquake observation system 100 according to the modification, the transfer unit transfers the waveform file registered in the transfer list with priority over the waveform file registered in the untransferred list.
Therefore, according to the earthquake observation system 100 according to the modified example, the waveform file generated based on the newly generated earthquake is preferentially transferred, so that the waveform file with high urgency can be backed up with priority. it can.

(Other variations)
For example, in the above embodiment, when transferring a waveform file to the server apparatus 1, only one waveform file is transferred. However, the present invention is not limited to this. For example, a plurality of waveform files can be transferred simultaneously by using a communication line such as Ethernet (registered trademark) that can transfer a plurality of files simultaneously.
Thereby, a plurality of waveform files registered in the transfer list can be simultaneously transferred, and a plurality of waveform files registered in the untransferred list can be simultaneously transferred. In addition, the waveform file registered in the transfer list and the waveform file registered in the non-transfer list can be transferred in parallel.
Accordingly, since the transfer time of the waveform file can be shortened, the work time required for the backup of the waveform file can be shortened.

In the above modification, the waveform file registered in the transfer list is transferred with priority over the waveform file registered in the non-transfer list. However, the present invention is not limited to this. For example, each waveform file may be weighted according to the priority order based on the elapsed time from the completion of generation, and sequentially transferred from the waveform file with the highest weight. In this case, weighting may be performed so that the shorter the elapsed time from the completion of generation, the higher the priority.
As a result, a newly generated waveform file is preferentially transferred, so that a waveform file with high urgency can be preferentially backed up.

  In the above modification, the waveform file registered in the untransferred list is transferred to the server device 1 at the timing when the occurrence of the earthquake is detected (see step S22 and step S23 in FIG. 7). It is not limited to this. For example, the waveform file registered in the untransfer list may be transferred to the server device 1 at the timing when the waveform file is registered in the untransfer list at the time of power recovery from a power failure (see step S21 in FIG. 7). .

  Moreover, in the said embodiment, although the server apparatus 1 is installed in the remote place away from the seismometer 2 more than predetermined distance, it is not limited to this. That is, it may be installed at a position less than a predetermined distance from the seismometer 2.
