  The present invention relates to, for example, an earthquake observation system, an earthquake observation method, an earthquake observation program, and a mobile terminal device that perform earthquake observation by forming a network using a mobile phone or the like.

  Conventionally, for example, an earthquake observation system that can collect earthquake waveform data from observation terminals installed in various places has been proposed (see Patent Document 1). That is, in this earthquake observation system, when an earthquake occurs, the observation terminal acquires waveform data and acceleration data of the earthquake.

Hereinafter, an embodiment of the present invention will be described with reference to FIGS.
FIG. 1 is a diagram illustrating a network configuration example of the earthquake observation / warning system according to the present embodiment.
In FIG. 1, the earthquake observation / warning system of the present embodiment constitutes an earthquake observation local network 7 with a plurality of portable terminals 1 to 5 existing in a short distance range such as each room 11 to 14 in the home. . And an earthquake is observed based on the vibration of each portable terminal 1-6 main body.

  For example, as a condition for the distance constituting the seismic observation local network 7, a short distance range of about a few dozen meters such as the rooms 11 to 14 in the home is set. In addition, for example, a time zone from night to early morning such as from 11 to 7 in the morning is set as a condition for the time zone to activate the earthquake observation mode.

For this reason, each portable terminal 1-5 is provided with the various functions shown below for performing an earthquake observation mode.
That is, each mobile terminal 1 to 5 constituting the earthquake observation local network 7 is equipped with a vibration sensor that detects vibration of the mobile terminal body. Moreover, each portable terminal 1-5 is provided with the function to observe the vibration of a portable terminal main body by starting the detection of the vibration of a portable terminal main body by a vibration sensor.

  Accordingly, each of the mobile terminals 1 to 5 automatically activates the earthquake observation mode when the above-described distance condition and time zone condition are satisfied. Thereby, each portable terminal 1-5 observes the vibration of a portable terminal main body in real time by starting the detection of the vibration of a portable terminal main body by a vibration sensor in each room 11-14 in a home.

  Moreover, each portable terminal 1-5 which comprises the earthquake observation local network 7 recognizes the number of the portable terminals which entered the earthquake observation local network 7, and notifies the number of portable terminals to each portable terminals 1-5. It has. Each of the mobile terminals 1 to 5 has a function of transmitting vibration detection information of the mobile terminal main body by the vibration sensor to another mobile terminal and receiving detection information of vibration of the other mobile terminal main body by the other mobile terminal. I have.

  Thereby, each portable terminal 1-5 can share the detection information of the vibration of the portable terminal in the earthquake observation local network 7. FIG. A central tabulation device that tabulates and stores vibration detection information, which has been necessary in the past, becomes unnecessary. For this reason, each process of totalization, storage, and readout of vibration detection information is not necessary. In addition, it is possible to prevent the earthquake observation process from being stopped due to a failure of the central counting device or an inability to communicate.

  Moreover, each portable terminal 1-5 which comprises the earthquake observation local network 7 determines with it being a vibration by an earthquake, when the number of the portable terminal main bodies which detected the vibration exceeds a threshold value by the communication result of the detection information of a vibration. It has a function. Moreover, each portable terminal 1-5 is provided with the function in which each portable terminal 1-5 performs the warning operation set beforehand by the determination result that it is the vibration by an earthquake.

  Accordingly, each of the mobile terminals 1 to 5 can determine that the vibration is caused by an earthquake when the number of mobile terminals exceeding the threshold value detects the vibration. Even when any one of the mobile terminals 1 to 5 breaks down or cannot communicate, the remaining mobile terminals 1 to 5 can make an earthquake determination. This threshold value is preset in advance in synchronization within the seismic observation local network 7.

  For example, when the default threshold value is 70%, it is assumed that only the mobile terminal 5 among the mobile terminals 1 to 5 constituting the earthquake observation local network 7 has not detected vibration. At this time, the number of mobile terminals that have detected vibration is four, which is 80% of the total five of the earthquake observation local network 7 and exceeds the threshold of 70%. Therefore, each portable terminal 1-4 determines with it being a vibration by an earthquake.

  At this time, each portable terminal 1-5 can sound or display a warning on the main body, notify other terminals, and communicate with other terminals. For example, a contact is made from my mobile terminal 1 in the room 11 to the grandfather's mobile terminal 5 in the room 14, and the situation is confirmed by the father's mobile terminal 2 in the other room 12, the mother's mobile terminal 3, and the brother in the room 13. Can be notified to the portable terminal 5.

Further, each of the mobile terminals 1 to 5 can send a control command to turn off the power or release the door lock to the information home appliance control system 6 in the kitchen 15.
Each of the mobile terminals 1 to 5 is applicable as long as it is a terminal mainly having a communication function such as a mobile phone and a PDA (Personal Digital Assistant).

The control unit 30 outputs control signals to the operation unit 26, the display unit 27, the communication circuit 22, the memory 25, and the speaker 24. Thereby, the communication function by transmission and reception is executed.

  In the earthquake observation mode, the earthquake observation application 39 is operated and executed on the operating system (OS) 40. By the operation / execution of the earthquake observation application 39, the operating system (OS) 40 issues an operation command to the driver program 41.

  Here, an example of an acceleration sensor that can be used as the vibration sensor 29 described above will be described. The performance of the acceleration sensor is, for example, maximum recording range: ± 1.5G, resolution: 0.001G, AD converter: 12bit, dynamic range: 64dB, sampling frequency: 100sps, recording frequency characteristics: 100Hz, output contents: X, Y, Z is a voltage corresponding to the acceleration value of each axis.

  The seismic intensity calculation of the seismic observation application 39 is obtained by, for example, an algorithm (calculation method) published by the Japan Meteorological Agency. The measured seismic intensity is calculated in the seismic observation application 39 by the following digital processing.

  In other words, each of the three components of the digital acceleration recording (horizontal motion 2 components (X, Y) and vertical motion 1 component (Z)), which is the output of the vibration sensor 29, is subjected to the procedures of Fourier transform, filter processing, and inverse Fourier transform. Apply a filter with the following characteristics. The filter processing used in the calculation of the measured seismic intensity is a filter that represents an intermediate characteristic between acceleration and velocity, a high cut filter, and a low cut filter.

Apply the above filter that emphasizes the low frequency side to the acceleration output, and use a value that lasts for 0.3 seconds or more instead of the maximum value itself. A vector waveform is synthesized from the three filtered output components obtained. When the total time for which the absolute value of the vector waveform is greater than or equal to a value a is calculated, a is calculated such that this is exactly 0.3 seconds.
Calculate measured seismic intensity I from this a using equation (1).

[Equation 1]
I = 2 log a + 0.94

  The operation of the mobile phone 20 configured as described above will be described using the following flowchart. Below, the earthquake observation application 39 in the application program 37 shown in FIG. 3 causes the CPU of the control unit 30 which is the computer of the mobile phone 20 shown in FIG. 2 to execute various functions in the earthquake observation mode. The operation is shown.

  That is, the control unit 30 of the mobile phone 20 reads information on the activation condition of the earthquake observation mode from the memory 25 to check whether or not the set condition is satisfied. The following processing is executed (step S1).

  For example, as a condition for the distance constituting the seismic observation local network 7, a short distance range of about a few dozen meters such as the rooms 11 to 14 in the home is set. In addition, for example, a time zone from night to early morning such as from 11 to 7 in the morning is set as a condition for the time zone to activate the earthquake observation mode.

The control unit 30 of each mobile phone 20 automatically activates the earthquake observation mode when the above-described distance condition and time zone condition are satisfied.
Next, the control unit 30 of the mobile phone 20 counts the number of mobile phones that have entered the earthquake observation local network 7 and notifies each mobile phone of the number of mobile phones (step S2). And the control part 30 of the mobile telephone 20 observes the vibration output from the vibration sensor 29 (step S3).

To do. At this time, the control unit 30 of the mobile phone 20 recognizes that a mobile phone has detected vibration (step S4).

Here, the control unit 30 of the mobile phone 20 determines whether or not the number of mobile phones that have detected vibrations exceeds a set threshold value based on the communication result of the vibration detection information (step S5).
In determination step S5, when the number of mobile phones that have detected vibration exceeds a set threshold value, the control unit 30 of the mobile phone 20 determines that the vibration is due to an earthquake.

  Moreover, when it determines with it being the vibration by an earthquake in judgment step S5, the control part 30 of the mobile telephone 20 performs the following warning operation | movement which each mobile telephone was preset. When it is determined in step S5 that the vibration is not caused by an earthquake, the process proceeds to step S6, the detected information is cleared, the process returns to step S3, and the processes and determinations from step S3 to step S5 are repeated.

  Further, when it is determined in the determination step S5 that the vibration is caused by an earthquake, the control unit 30 of the mobile phone 20 sounds or displays a warning on the main body (step S7). The warning operation in step S7 is an essential operation in each mobile phone 20, but the following processes from step S8 to step S12 are operations that can be selectively set in each mobile phone 20.

Further, when it is determined in the above-described determination step S5 that the vibration is caused by an earthquake, the control unit 30 of the mobile phone 20 sends an SOS message to the emergency contact number 119 set in advance via the telephone network. (Step S8).
In addition, the control unit 30 of the mobile phone 20 receives deeper text broadcast information such as VICS via the FM receiving circuit 34 and notifies this to other mobile phones (step S9).

  After the processing from step S7 to step S12, the control unit 30 of the mobile phone 20 determines whether or not to end the earthquake observation mode (step S13). Here, the control unit 30 of the mobile phone 20 reads from the memory 25 information related to the activation condition of the earthquake observation mode shown in step S1. Thus, when the number of mobile phones 20 increases or decreases during observation, the earthquake observation local network 7 is reconstructed.

Also at this time, it is checked whether or not the start condition of the set seismic observation mode is satisfied, and if it is satisfied, the process returns to step S2, and the processes and determinations from step S2 to step S12 are repeated.
If not, the process proceeds to step S14, switches to the communication mode (step S14), and ends.
