Embodiments of the present invention will be described below with reference to the drawings.
FIG. 1 is a block diagram showing the configuration of the earthquake information providing system according to this embodiment. As shown in FIG. 1, this earthquake information providing system is composed of a mobile phone base station 1 and a center station 2 (earthquake monitoring station) connected to the base station 1 via a communication network. . The base station 1 has a control board 10, a monitoring board 11, and a backplane 12 as shown in the figure. Although omitted in FIG. 1, the base station 1 appropriately has other configurations necessary for a mobile phone base station (for example, a communication function with an antenna and a higher station) and a communication function with the center station 2. ing.

  The control board 10 is a board of a main control unit that controls the operation of the entire base station 1, and includes a base station control unit 10a that functions as the main control unit. The monitoring board 11 is a monitor board for detecting the vibration of the base station 1 due to an earthquake, and includes a board control unit 11a and a vibration detection unit 11b. The board controller 11a monitors the vibration of the base station 1 based on the vibration detected by the vibration detector 11b. The vibration detection unit 11b detects the vibration of the base station 1 due to an earthquake or the like, and supplies an output signal indicating the magnitude of the vibration or the like to the substrate control unit 11a. In the monitoring board 11, the board control section 11a monitors the vibration of the base station 1 by the output signal from the vibration detection section 11b, and when the vibration detection section 11b detects a vibration of a certain level or more, It is determined that an earthquake has been detected at the installation location.

  As the vibration detection unit 11b for detecting an earthquake in this manner, any detection means capable of detecting vibration can be used. For example, the vibration detection unit 11b is configured using an inertial sensor such as an acceleration sensor or a gyro. can do. In addition, since there are pitch and roll in an earthquake, the vibration detector 11b may detect both vertical and roll vibrations. For example, when the vibration detection unit 11b is configured by an acceleration sensor, by providing two linear accelerometers whose input axis directions are orthogonal to each other, pitch vibration and roll vibration can be detected. When the vibration detection unit 11b is configured, it is possible to distinguish and detect pitch vibration and roll vibration depending on the direction in which the inertial force is applied.

  The backplane 12 is a wiring board that interconnects the control board 10, the monitoring board 11, and the center station 2. In the base station 1, the control board 10 and the monitoring board 11 are stored in a rack together with boards provided for each of other application functions (such as a communication function with a mobile phone required for the base station and a communication function with the center station 2). These boards are connected to the backplane 12, and the control board 10, the monitoring board 11, and the center station 2 exchange signals via the backplane 12. The center station 2 that communicates with the base station 1 by sending and receiving this signal makes a final determination as to whether or not an earthquake has occurred and provides information about the earthquake.

  In this earthquake information providing system, each base station 1 constituting the mobile phone network has the above-described control board 10, monitoring board 11 and backplane 12, respectively. Furthermore, these base stations 1 each have storage means for storing disaster information to be provided when an earthquake occurs. Examples of disaster information to be provided include estimated seismic intensity of earthquakes and traffic information (possibility of transportation stoppage, etc.), and tsunami information (possibility of occurrence of tsunami, etc.) for base stations 1 in coastal areas. It is possible to incorporate different contents according to the area of each base station 1, the scale of the earthquake, the city center, the coastal area, and the like. In the earthquake information providing system, character string data, voice data, and the like of the disaster information message for notifying such disaster information are stored in a database in advance, and the disaster information message is stored in the storage unit such as the control board 10 in each base station 1. A database is stored, and each base station 1 holds in advance various disaster information messages according to the assumed earthquake situation.

Next, the operation of the earthquake information providing system configured as described above will be described.
FIG. 2 is a sequence diagram showing an operation procedure for providing information related to an earthquake disaster by the earthquake information providing system when an earthquake occurs. In this earthquake information providing system, the board control unit 11a provided on the monitoring board 11 in each base station 1 constantly monitors the vibration by monitoring the output signal from the vibration detection unit 11b. And if the vibration detection part 11b of a certain base station 1 detects vibration and the board | substrate control part 11a determines with the vibration detected by the vibration detection part 11b of the said base station 1 being a vibration more than a fixed level, the said base station 1 is a vibration detection state ("vibration detection" in FIG. 2).

  The base station 1 that has detected the vibration immediately notifies the center station 2 of the information related to the vibration as “shake information notification”. This shaking information includes information indicating the magnitude of the vibration detected by the vibration detector 11b. Such shaking information is sent from the monitoring board 11 to the center station 2 for notification, or sent from the monitoring board 11 to the control board 10 and sent from the control board 10 to the center station 2 for notification. The center station 2 determines whether or not the vibration detected by the base station 1 is caused by an earthquake by comprehensively evaluating the shake information from the adjacent base station 1. That is, when the center station 2 collates information from each base station 1 and receives shake information from a plurality of adjacent base stations (a plurality of base stations 1 adjacent to the terminal accommodation area), the center station 2 Determine that an earthquake occurred.

  Subsequently, the center station 2 instructs the disaster information message to be notified to the mobile phone user according to the determined earthquake area and scale to the base station 1 that issued the “shake information notification”. To emit. Since each base station 1 holds the disaster information message in the database in advance, the “disaster information notification request” from the center station 2 includes the disaster information message to be transmitted to the mobile phone from among the disaster information messages. Only designated information such as a designated message number is transmitted to the base station 1. Thus, the base station 1 that has received the “disaster information notification request” sends a disaster information message designated by the center station 2 as “disaster information notification” to all mobile terminals located in the terminal accommodation area of the local station. To be notified. This “disaster information notification” is performed by, for example, broadcasting to all mobile terminals in the area, individual transmission to each mobile terminal in the area, etc., and when the mobile terminal of the notification destination is a mobile phone having an e-mail function If an e-mail is sent with the character string of the disaster information message as the text, and the mobile terminal being notified is a mobile phone that does not have an e-mail function, the disaster information message will be displayed when a call is received Is notified by voice.

  According to the earthquake information providing system, as described above, the base station 1 itself detects the earthquake and transmits the information of the earthquake detection, and the center station 2 takes into account the information from the other adjacent base station 1. Since the final determination of the occurrence is made and the disaster information message is immediately notified, the earthquake information can be provided promptly when an earthquake occurs. In addition, since the disaster information message is specified according to the earthquake detected in the notification area, it is possible to provide accurate earthquake information of the earthquake that has occurred.

  Furthermore, in this earthquake information provision system, the center station 2 issues a “disaster information notification request” at the same time (if necessary or if an arrangement is made in advance) Report earthquake information based on earthquake detection information to other organizations ("Earthquake Report" in Fig. 2), and acquire detailed information on earthquakes at any time by "Detailed Information Notification" from that organization. May be. In this case, the center station 2 obtains the details newly obtained by exchanging information with the Meteorological Agency etc. for the base station 1 in the area where it is determined that more detailed earthquake information should be provided according to the area and scale of the earthquake Instructing more detailed disaster information notification based on the information (“detailed disaster information notification request”). Accordingly, the base station 1 that has received the instruction notifies more detailed disaster information from the center station 2 as “detailed disaster information notification” to all mobile terminals located in the terminal accommodation area of the local station.

  Here, according to the report of the earthquake information from the center station 2, it is possible to notify the Japan Meteorological Agency and the like that an earthquake has occurred and to provide more accurate information on the earthquake. That is, a large number of mobile phone base stations 1 are installed throughout the country, and the base stations 1 are scattered far more densely than seismic observation points such as seismometers installed in various places. On the other hand, if the base station (the base station 1) of the earthquake information providing system is provided with the vibration detection unit 11b such as an acceleration sensor in these existing base stations to perform predetermined signal exchange. Can be realized.

  Therefore, it is possible to detect earthquakes at individual base stations throughout the country, and if the base station obtains vibration data directly detected in each subdivided area, earthquakes will be detected in more detail. It is possible to detect earthquakes and collect earthquake information that is very effective for earthquake area and earthquake information notification (by making the base station a base for collecting earthquake information, detailed information It becomes possible to collect.) As a result, the Japan Meteorological Agency etc. can grasp the situation of the earthquake more accurately, and it is more reliable for mobile phone users based on the vibration data obtained at the base station as information from the base station. It is also possible to provide information such as seismic intensity.

  In the earthquake information providing system, as described above, the center station 2 collates information from adjacent base stations to make a final determination of the occurrence of an earthquake. This is to prevent an earthquake from being detected by erroneous detection at each base station 1 or the like. For example, in the base station 1 in which there is a construction site or factory in the vicinity or an accident has occurred in the vicinity, there is a possibility that the monitoring board 11 may erroneously detect that the monitoring board 11 is an earthquake due to the construction, accident, factory or the like. There is a possibility that information on earthquake detection may be erroneously transmitted due to a failure in the base station 1 or the like.

  For this reason, in the center station 2, if earthquake detection information is not transmitted from another adjacent base station 1 even if earthquake detection information is transmitted from a certain base station 1, the transmitted earthquake detection is detected. The information is discarded and it is not determined that an earthquake occurred. As a result, this earthquake information provision system can accurately detect the earthquake by accurately estimating the earthquake occurrence area and the magnitude of the earthquake, eliminating false detection of earthquakes due to construction, accidents, factories, breakdowns, etc. It has become. The estimation of the earthquake occurrence area and the magnitude of the earthquake can be performed more accurately by detecting the earthquakes at the base stations 1 scattered throughout the country and collecting the information of the earthquake detection.

  In the “disaster information notification request”, only the specified information of the disaster information message is transmitted to the base station 1, but the disaster information message itself to be notified to the base station 1 can also be transmitted from the center station 2. It is. However, in the event of an earthquake, traffic on the mobile phone network increases due to each user's access, etc., so it is possible to reduce traffic by transmitting only the designated information. Furthermore, the disaster information message is prepared in advance by the base station 1 and the disaster information message is notified in response to the instruction, so that information can be provided more quickly. The above-described form of transmission is preferred.

  By the way, as one of the control techniques of the base station, there is a technique in which a pseudo-test terminal is built in the base station, and the radio unit is monitored and tested from a remote location such as the center station. FIG. 3 is a diagram showing an outline of the configuration of the base station 3 incorporating the test pseudo terminal. As illustrated, the base station 3 includes a base station main control unit 30 that controls the operation of the entire base station 3, an antenna 31 connected to the radio unit of the base station main control unit 30, and the base station main control unit 30 and the antenna. A test pseudo-terminal 32 is connected between 31.

  The test pseudo-terminal 32 is equipped with an interface such as UART (Universal Asynchronous Receiver / Transmitter (Universal Asynchronous Receiver / Transmitter)) or USB (Universal Serial Bus (Universal Serial Bus)). A test request is received from the station main controller 30 and a result response is transmitted to the base station main controller 30. However, the test pseudo terminal 32 is provided in the vicinity of the base station 3 and is connected by wire between the base station main control unit 30 and the antenna 31, but the communication with the base station main control unit 30 is performed wirelessly. There is also.

  In such a configuration, the test pseudo-terminal 32 performs a transmission / reception operation test (for example, a call test or a call test) via the radio unit test path in the drawing in response to a test request from the base station main control unit 30. I do. The base station main control unit 30 receives the test result as a result response, so that it can be confirmed whether or not the operation of the radio unit at the antenna input / output terminal is normal.

  For example, a base station of a data communication network based on 1xEV-DO (1x Evolution Data Only) includes a TAT (Test Access Terminal (pseudo terminal function)) board corresponding to the test pseudo terminal 32, and This is an example. The base station monitors and tests the radio unit while controlling what test is performed between the TAT board and the base station main control unit. For example, a signal output from the wireless unit to the outside is input to an AT (Access Terminal) on the TAT board, and the wireless unit is tested by the function of the AT as a mobile terminal.

  The above earthquake disaster information providing system detects an earthquake by providing a vibration detection unit such as an acceleration sensor in the base station, but it should be easily implemented for a base station incorporating such a test pseudo terminal. Is possible. In other words, since the test pseudo terminal built in the base station only needs to be able to perform a monitoring test of the radio unit such as incoming / outgoing calls, it usually has only a limited basic function and other functions. There is no need. However, mobile terminals are equipped with various functions such as cameras, microphones and speakers as seen in recent mobile phones, etc., and acceleration sensors are installed for the stability of GPS (Global Positioning System) functions. Things are also popular, and have high functionality and high performance.

  In a test terminal such as a TAT board, since such a function is simply deleted as unnecessary, it is easy to install it without deleting it using recent mobile terminal technology. A monitoring board having a vibration detection function like the board 11 can be easily configured. Therefore, in a base station with a built-in test pseudo-terminal, an acceleration sensor or the like is provided and a vibration detection function is installed in the test pseudo-terminal, so that functions that have been deleted as functionally unnecessary are effective. It is possible to implement the above-mentioned earthquake information providing system that detects earthquakes by utilizing them.

  Specifically, the monitoring board 11 is equipped with a mobile terminal function unit serving as a test pseudo terminal as an equivalent to the vibration detection unit 11b, and the mobile terminal function unit is used for earthquake detection such as an acceleration sensor. Built-in sensor. Thereby, the configuration of the base station 1 can be realized by using a test pseudo terminal, and it is possible to detect an earthquake and notify the center station 2 or disaster information as described above. When an earthquake occurs, accurate earthquake information can be provided promptly. Conventionally, there was no need for a pseudo-terminal for testing with a built-in acceleration sensor, but it is possible to provide earthquake information quickly by detecting earthquakes using its vibration detection function. A disaster information provision system can be realized.

  In the above embodiment, when the center station 2 receives shaking information from a plurality of adjacent base stations, it is determined that an earthquake has occurred in the area of the adjacent base station. Each base station determines the occurrence of vibrations above a certain level, and the adjacent base station is notified of the occurrence of vibrations above a certain level. In some cases, the occurrence of an earthquake may be authorized.
