Description

  The present invention relates to an earthquake notification system for notifying an earthquake alarm.

  As a conventional earthquake alarm system, the earthquake alarm display panel that displays earthquake information and generates an earthquake alarm is installed at a specific distance from the display of the earthquake alarm display panel, and is displayed on the earthquake alarm display panel There is a printing device that prints earthquake information on the paper, and a display clear instruction means provided on the printing device that clears the display of the earthquake occurrence time and seismic intensity level displayed on the earthquake warning display panel (for example, Patent Document 1). The installation position of the earthquake warning display panel is selected as a high place in consideration of easy viewing.

JP 2003-161784 A

  The earthquake notification system described in Patent Document 1 has the following problems. The earthquake warning display panel that displays earthquake information can only display earthquake information, so basically nothing is displayed except when an earthquake occurs, and it only occupies the installation location. . In other words, nothing is used normally.

  It is an object of the present invention to provide an earthquake notification system that can display not only an earthquake warning but also useful information except when an earthquake occurs.

  The earthquake notification system of the present invention is connected to a seismometer and a seismometer that calculates earthquake prediction information by detecting an initial tremor among seismic waves and outputs an earthquake warning signal based on the calculated prediction information. An FM multiplex display device for scrolling and displaying FM multiplex broadcast character information. When the FM multiplex display device receives an earthquake warning signal, the earthquake character information related to the earthquake takes precedence over the FM multiplex broadcast character information. It is characterized by being displayed.

  In the present invention, since the seismic intensity meter is provided, by detecting the initial tremor (P wave), the prediction information of the main motion (S wave) of the seismic wave can be obtained, and the earthquake warning signal can be output based on this prediction information. Moreover, the seismic intensity meter enables direct measurement of seismic waves, and information on earthquakes such as prediction information can be obtained immediately. In addition, since FM multiplex display can scroll and display FM multiplex broadcast text information, useful information such as FM multiplex broadcast news can be displayed. Furthermore, when an earthquake warning signal is input, the FM multiplex display device connected to the seismometer displays the earthquake text information related to the earthquake with priority over the text information of the FM multiplex broadcast. By displaying character information, an earthquake alarm can be notified, and FM multiplex broadcast character information is displayed at times other than when an earthquake occurs, that is, during normal times, so that useful information can be transmitted.

  The calculation of earthquake prediction information typically involves calculating the arrival time of the main motion (S wave), the maximum seismic intensity, etc. from the detected initial tremor (P wave) wave direction and amplitude information. It is. That is, the earthquake prediction information is information obtained by predicting the arrival time of the main motion (S wave), the maximum seismic intensity, and the like calculated by this calculation. Note that the calculation of the earthquake prediction information is not limited to the above, and may be, for example, one that predicts at least that a major movement (S wave) will soon arrive from the detected initial fine movement (P wave). . In this case, a sensor for detecting seismic waves and calculation of prediction information can be simplified.

  Preferably, the earthquake notification system includes display message storage means for storing earthquake character information relating to the earthquake, and the FM multiplex display device stores the earthquake stored in the display message storage means based on the earthquake warning signal input from the seismometer. Display character information. In this case, the configuration can be simplified by storing earthquake character information related to earthquakes as a standard message in the display message storage means in advance.

  Preferably, the earthquake notification system includes voice alarm means for outputting voice information and voice message storage means for storing voice information when an earthquake warning signal from a seismometer is input. In this case, not only the earthquake character information can be displayed by the FM multiplex display device but also a voice alarm can be notified, so that an earthquake alarm can be more reliably notified to the surroundings.

  According to the present invention, it is possible to provide an earthquake notification system that can display not only an earthquake warning but also useful information except when an earthquake occurs.

It is a figure showing roughly the composition of the earthquake information system concerning this embodiment. It is a block diagram which shows the structure of the earthquake notification system which concerns on this embodiment. It is a front view which shows the example of a display of the FM multiple display apparatus which concerns on this embodiment. It is a figure which shows schematically the structure of the modification of the earthquake alerting | reporting system which concerns on this embodiment.

  Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. In the description, the same reference numerals are used for the same elements or elements having the same function, and redundant description is omitted.

  With reference to FIGS. 1-3, the earthquake alerting system 1 which concerns on this embodiment is demonstrated. FIG. 1 is a diagram schematically illustrating a configuration of an earthquake notification system 1 according to the present embodiment, FIG. 2 is a block diagram illustrating a configuration of the earthquake notification system 1 according to the present embodiment, and FIG. It is a figure for demonstrating the scroll display of the FM multiple display apparatus 10 of the earthquake alerting system 1 which concerns on a form.

  As shown in FIGS. 1 and 2, the earthquake notification system 1 includes a seismic intensity meter 20 and an FM multiple display device 10 connected to the seismic intensity meter 20. The seismic intensity meter 20 detects a seismic wave and its detection result. The earthquake warning is issued by analyzing the above and the earthquake warning is displayed by the FM multiple display device 10 to notify the earthquake warning. The earthquake alarm system 1 is installed in public facilities where it is considered effective to notify an earthquake alarm, such as an airport, a station, a government office, a hotel, or a bank, but to an apartment house, office, sports gym, or convenience store. It is also suitable for installation.

  The seismic intensity meter 20 is configured to calculate earthquake prediction information by detecting initial microtremors (P waves) among the seismic waves, and to output an earthquake warning signal based on the calculated prediction information. That is, it has a so-called early earthquake detection function.

  The early earthquake detection function uses the characteristic that the initial tremor (P wave) of the seismic wave is faster in propagation speed (about 1.7 times) than the main motion (S wave) that causes great damage. It is a function that calculates the strength of shaking of an earthquake (S wave) that arrives late and the grace time (arrival time) until arrival by detecting and analyzing the P wave that can be generated. More specifically, the early earthquake detection function is such that the seismic sensor 21 of the seismometer 20 detects the P wave, and detects the main motion from the detected P wave amplitude and the direction of the shake (three direction components). In other words, it is a function that calculates the magnitude (magnitude) of an earthquake and the distance to the location of the earthquake, and calculates the strength (seismic intensity) and arrival time of the earthquake (S wave). In other words, it is a function that calculates earthquake prediction information from the detected P wave. In this embodiment, a seismometer that calculates the seismic intensity of the predicted earthquake and the grace time until arrival is used as the prediction information. However, only the arrival of a large earthquake (for example, seismic intensity 5 or more) is assumed to be the prediction information. A simple seismometer may be used. In this case, the configuration of the seismic intensity meter can be simplified.

  In addition to the early earthquake detection function, the seismic intensity meter 20 of the present embodiment also has a function of measuring a seismic intensity (a seismic intensity at the time of detecting a seismic wave) in real time, which is a normal function. The seismic intensity meter 20 is preferably installed in a place that is not easily affected by artificial noise such as automobile vibration. Moreover, although this embodiment demonstrates the case where the seismic sensor 21 is built in the seismic intensity meter 20, it is good also as a different body. When the seismic sensor 21 is configured separately from the seismometer 20, only the seismic sensor 21 may be installed in a place that is not easily affected by vibration noise.

  The seismic intensity meter 20 has a plurality of or one contact, and is configured to perform contact output (contact ON / OFF) as an earthquake alarm signal. In the present embodiment, there are a plurality of contacts, and specifically, a case where the number of contacts is four will be described. In this case, a plurality of alarms can be set to correspond to a plurality of contacts (for example, a plurality of alarm levels), and by turning each contact ON / OFF (contact output of an earthquake alarm signal), a plurality of alarms can be set. Can output various types of earthquake warning signals. Thereby, for example, as will be described later, a plurality of types of earthquake character information can be displayed on the FM multiplex display device. Moreover, by using the output of the earthquake warning signal as a contact output, a simple system can be achieved as compared with a case where a complicated signal such as a signal including earthquake prediction information is output as the earthquake warning signal. Moreover, if it is a contact output, it can be easily connected with external apparatuses, such as an elevator control panel, an electric control panel, and a gas control panel. In the present embodiment, a plurality of (four) contacts have been described, but one contact may be used. In this case, one type of earthquake warning signal cannot be output, but the configuration can be further simplified and an inexpensive product can be realized.

  The seismometer 20 is configured to determine a warning level from the prediction information. The alarm level is determined based on the magnitude of the predicted information seismic intensity. The alarm level may be set in a plurality of stages, for example, seismic intensity 3 (level 1), seismic intensity 3 or more and less than 5 (level 2), seismic intensity 5 or less (level 3). The seismometer 20 outputs an earthquake alarm signal corresponding to the alarm level, that is, a contact output. In the present embodiment, when the determined alarm level is level 1 described above, an earthquake alarm signal is not output.

  By the way, the earthquake notification system 1 includes the seismic intensity meter 20 having the seismic sensor, so that, for example, the radiation characteristics and propagation of the earthquake are compared with those in which the seismic intensity meter 20 is not provided and the earthquake information is obtained from the outside (the Japan Meteorological Agency) There is an advantage that it is possible to predict and measure the seismic intensity specific to the installation point, taking into account the characteristics and observation point effects.

  The FM multiplex display device 10 is electrically connected to the seismometer 20 and scrolls and displays text information of FM multiplex broadcasting. The character information of FM multiplex broadcasting is character information obtained by receiving FM multiplex broadcasting, for example, news, weather forecast, traffic information, sports news, and the like. Note that the FM multiple display device 10 also has a function of displaying any message such as facility guidance, advertisements, and contact items.

  The FM multiplex display device 10 includes a display unit 11 capable of scroll display, an FM multiplex character broadcast receiver 12 having a function of receiving FM multiplex broadcast and obtaining character information, a display unit 11 and an FM multiplex character broadcast receiver. 13 and a control unit 12 that controls the control unit 12. In FIG. 2, the display unit 11 and the control unit 12 are shown as separate bodies, but may be configured integrally.

  A seismic intensity meter 20 is electrically connected to the control unit 12 so that an earthquake alarm signal output from the seismic intensity meter 20 can be input. The control unit 12 includes an FM multiplex teletext receiver 13 and a display message storage unit 15 as display message storage means for storing earthquake character information to be displayed on the display unit 11. In the present embodiment, the FM multiplex teletext receiver 13 and the display message storage unit 15 are described as being built in the control unit 12, but each may be configured separately.

  When the earthquake warning signal output from the seismometer 20 is input, the control unit 12 is configured to perform control to display the earthquake character information related to the earthquake with priority over the character information of FM multiplex broadcasting. The earthquake character information is a message for notifying an earthquake to be displayed on the display unit 11 and is information by characters. For example, the message is “It is an earthquake!

  The control unit 12 is configured to display the earthquake character information stored in the display message storage unit 15 based on the earthquake alarm signal from the seismometer 20. The display message storage unit is a storage medium such as a flash memory or a hard disk. More specifically, the control unit 12 reads out earthquake character information corresponding to the alarm level of the input earthquake alarm signal and displays it on the display unit 11. For example, if the input earthquake warning signal indicates seismic intensity 5 or lower (level 3), the corresponding earthquake text information (message), for example, “An earthquake with seismic intensity 5 or lower!” Is displayed on the display unit 11.

  Further, the control unit 12 can input (store) arbitrary character information (message) input by an input means (not shown) to the display message storage unit 15. Arbitrary messages can be input by connecting an input means such as a keyboard to the control unit 12, and an interface to which a terminal such as a personal computer, a mobile phone, or a PDA can be connected is configured as the input means of the control unit 12. It is good also as input possible. In this embodiment, a message can be input by infrared communication. Thereby, the display unit 11 can display text information such as information about the installed facility and guidance items as an arbitrary message. Further, the control unit 12 can control the display of the character information stored in the display message storage unit 15. That is, it is possible to set when each character information stored in the display message storage unit 15 is to be displayed, and display on the display unit 11 can be controlled based on this setting. In addition, when displaying arbitrary character information, it is good to interrupt and display the character information display of FM multiplex broadcasting. That is, when FM multiplex broadcast character information is displayed on the display unit 11, the display is stopped and arbitrary character information is preferentially displayed.

  The display unit 11 is electrically connected to the control unit 12 and its display is controlled. In the present embodiment, as shown in FIG. 3, one that scrolls and displays a character string of one line is used. The display unit 11 is typically a fluorescent display tube (vacuum fluorescent display). By using a fluorescent display tube, scroll display with high visibility can be performed. A fluorescent display tube is used in the market. In addition, by using a fluorescent display tube, it is possible to display earthquake character information, that is, the arrival of an earthquake soon, greatly and clearly, so that it can be easily viewed from a remote location.

  The display unit 11 displays the received FM multiplex broadcast text information as shown in FIG. 3A during normal times (except when an earthquake occurs). When an alarm signal is input, as shown in FIG. 3B, the display is switched from character information such as FM multiplex broadcasting, and the earthquake character information is scroll-displayed.

  The earthquake notification system 1 further includes a voice alarm device 40 as voice warning means for outputting voice information when an earthquake warning signal from the seismometer 20 is input. The voice alarm device 40 has a voice message storage unit 41 as voice message storage means for storing voice information. The voice warning device 40 is configured to read voice information stored in the voice message storage unit 41 in advance when an earthquake warning signal is input and to output the voice information through a built-in speaker 42. The voice information is a message that reads out the earthquake character information displayed on the FM multiplex display device 10, for example, “It is an earthquake. Note that the audio information to be output includes an alarm sound and a buzzer sound in addition to the message.

  Furthermore, the earthquake notification system 1 includes a check switch 51. The check switch 51 has a plurality of push buttons. By pressing the buttons, the earthquake character information stored in the display message storage unit 15 can be displayed on the display unit 11. The check switch 51 can easily confirm the contents of the earthquake character information stored in the display message storage unit 15, which is convenient for inspection and maintenance, for example. The plurality of push buttons may be configured to correspond to a plurality of pieces of earthquake character information stored in the display message storage unit 15. Also, the check switch 51 can output the voice information stored in the voice message storage unit 41 by the voice alarm device 40.

  In the present embodiment, the FM multiple display device 10, the seismometer 20, the sound alarm device 40, and the check switch 51 are connected via the terminal 30. By doing in this way, it can be set as a simple connection form and installation is easy.

  Here, the operation of the earthquake notification system 1 will be described. In the earthquake notification system 1, when the seismic wave is not detected by the seismic intensity meter 20, the FM multiplex display device 10 displays text information such as breaking news obtained by the FM multiplex text broadcast receiver 13 on the display unit 11. Is scrolled. At this time, the seismometer 20 continuously monitors seismic waves.

  When an earthquake occurs, the seismic intensity meter 20 first detects a P wave of the seismic wave, and calculates prediction information (seismic intensity, arrival time) of the earthquake (S wave) from the detection result. The seismic intensity meter 20 determines an alarm level from the calculated prediction information, and performs contact output (earthquake alarm signal output) corresponding to the determined alarm level.

  When the seismic alarm signal corresponding to the alarm level from the seismometer 20 is input, the control unit 12 of the FM multiplex display device 10 reads the earthquake character information corresponding to the alarm level of the input signal from the display message storage unit 15 and displays it. Scroll display on unit 11. At this time, if the FM multiplex broadcast character information is displayed on the display unit 11, the display is immediately stopped and the earthquake character information is displayed (interrupted display).

  At the same time, the earthquake warning signal output from the seismic intensity meter 20 is also input to the voice alarm device 40. When receiving an earthquake alarm signal corresponding to the alarm level, the audio alarm device 40 reads out the audio information corresponding to the alarm level of the input signal from the audio message storage unit 41 and outputs it from the speaker 42.

  As described above, the earthquake notification system 1 normally scrolls the received FM multiplex broadcast character information by the FM multiplex display device 10 and, when an earthquake occurs, the FM multiplex display device 10 scrolls the earthquake character information. Then, an alarm of earthquake is notified by the output of audio information by the audio alarm device 40.

  Here, with reference to FIG. 4, the earthquake notification system 101 for apartment houses as another Example of an earthquake notification system is demonstrated. The earthquake notification system 101 for an apartment house is installed in an apartment house having a plurality of dwelling units. The earthquake notification system 101 for apartment houses is connected to the seismic intensity meter 20 as compared with the earthquake notification system 1 described above, and an alarm control panel 60 that delivers an earthquake alarm based on the input of an earthquake alarm signal from the seismic intensity meter 20 The difference is that it includes an interphone 71 connected to the alarm control panel 60 and arranged in each dwelling unit for notifying an earthquake alarm distributed from the alarm control panel 60. Further, the above-described voice alarm device 40 and the check switch 51 are built in the alarm control panel 60. In this case, since the voice alarm device 40 and the check switch 51 need not be separately configured, the system can be simplified. The FM multiple display device 10 is typically installed in a management room, but may be installed in a common facility (such as a conference room or a lobby).

  The alarm control panel 60 is installed in the management room and is connected to the seismometer 20 so as to be able to input an earthquake alarm signal. That is, an earthquake alarm signal corresponding to the alarm level is input to the alarm control panel 60 as in the FM multiple display device 10. The alarm control panel 60 is configured to be able to distribute earthquake alarms for residents to a plurality of interphones 71 when an earthquake alarm signal output from the seismometer 20 is input. This earthquake alarm includes an audio signal that can be reproduced by an interphone, for example, an audio message such as “Earthquake. The alarm control panel 60 has a display 61, and is configured to display a preset earthquake alarm display when an earthquake alarm signal is input. In addition, you may comprise so that the earthquake alarm display of the display 61 may be changed with the alarm level of an earthquake alarm signal like the FM multiple display apparatus 10. FIG.

  The interphone 71 is provided in each dwelling unit of the collective housing, and is connected to be able to input an earthquake alarm from the alarm control panel 60. The interphone 71 has a display 72 and a speaker 73. When an earthquake alarm is input from the alarm control panel 60, the interphone 71 displays a preset earthquake alarm display (display similar to the display on the display 61 of the alarm control panel). It is configured to display on the display 72 and output an earthquake alarm from the speaker 73. Here, the earthquake alarm output from the speaker 73 is described as being delivered from the alarm control panel 60. However, an alarm message is registered in the interphone 71 in advance and an earthquake alarm is input from the alarm control panel 60. A registered alarm message may be output.

  With the collective housing earthquake notification system 101 as described above, an earthquake alarm can be distributed by an interphone installed in each dwelling unit.

  The preferred embodiments of the present invention have been described above. However, the present invention is not necessarily limited to the above-described embodiments, and various modifications can be made without departing from the scope of the present invention.

  As described above, in the present embodiment, the earthquake alarm signal output by the seismometer is described in the case of the contact output (ON / OFF signal), but the contact signal (ON / OFF signal) is not an electrical signal including earthquake prediction information, That is, an electric signal including the magnitude (seismic intensity) and arrival time of the earthquake may be used. In this case, the FM multiple display device 10 is configured to also display the prediction information included in the input earthquake warning signal. That is, the numerical value of the input prediction information is displayed. For example, as earthquake text information, the seismic intensity value of predicted information is displayed in XX of “An earthquake of seismic intensity XX will arrive in △ seconds!”, And the numerical value of arrival time of predicted information is displayed in △△. To do. In this way, more accurate information about the earthquake can be displayed.

  Further, the seismometer may be connected to an elevator control panel so that an earthquake warning signal is output to the elevator control panel, and the elevator may be configured to perform an operation such as emergency stop.
