Description

  The present invention relates to a communication device connected to a telephone line provided by a communication company such as NTT, and more particularly to a communication device that can be used as a lighting fixture when an emergency earthquake warning distributed by the Japan Meteorological Agency is detected.

  In recent years, with the development of communication infrastructure, various additional services related to communication have become widespread. In particular, telephone devices that can receive various services by connecting to a wide-area communication network such as an IP telephone network or the Internet in addition to a general telephone line are widely used.

  As one of the functions of such a telephone device, there is a telephone device having a function of receiving an emergency earthquake bulletin distributed by the Japan Meteorological Agency when an earthquake occurs. Earthquake early warning is an information distribution service that will be implemented from October 1, 2007 AD. The user can use this service by purchasing a telephone device corresponding to the earthquake early warning and making a contract with a distribution service company for the earthquake early warning.

  By connecting the telephone device to a wide area communication network such as the Internet, the contract user can receive various types of information regarding the earthquake through the communication network when an earthquake occurs. The telephone device that received the earthquake occurrence notification uses the regional information recorded in advance in the telephone device, etc., and feels the strongest to the human body among the predicted seismic intensity and main motion (= earthquake motion) in the area where the telephone device is installed. The estimated time at which the portion (usually S wave) will reach is calculated. The calculation result is notified to the user, for example, by displaying an image on a liquid crystal panel or outputting sound through a speaker. As a result, the user can cope with an earthquake such as being hidden under the desk before the main motion arrives from the epicenter.

  Patent Document 1 discloses an image processing apparatus that can suppress the possibility of a secondary disaster such as a fire due to an earthquake as compared with the conventional apparatus as an apparatus capable of receiving the emergency earthquake warning as described above. The image processing apparatus includes a communication control unit that performs communication with an external device, and a power source control unit that changes an energization state inside the apparatus.

  Then, when the communication control means receives the earthquake early warning from the external device, the power supply control means is controlled to change the energization state. By controlling the power supply based on external information in this way, it is possible to prevent erroneous detection of earthquakes due to vibrations other than earthquakes, such as when working nearby or accidentally colliding with equipment, without compromising convenience. Safety can be ensured.

Further, in relation to the above, Patent Document 2 discloses a cordless telephone system in which a wireless terminal device capable of wireless communication with a parent device determines that a power failure has occurred at an external power source and turns on illumination. In this cordless telephone system, the handset constantly monitors the presence or absence of power supply from the energizer. When it is detected that the power supply has been cut off, the communication means determines whether communication with the parent device is possible, and determines that a power failure has occurred if communication is not possible. And a subunit | mobile_unit functions as a lighting fixture, when an illumination control means lights an illumination means.

No function has been disclosed or suggested.

  Further, the cordless telephone system disclosed in Patent Document 2 cannot detect a power failure when the parent device has a battery or an emergency power supply because communication between the parent device and the child device is possible even during a power failure. . Moreover, there is a possibility that a power failure may be erroneously detected in the case where communication with the parent device cannot be performed due to a factor other than the power failure, for example, a communication failure, and the detection accuracy is not necessarily high.

  Moreover, according to the structure of this invention, since the subunit | mobile_unit lights all the light emission members with the maximum output at the time of a power failure, it can obtain more light quantity. Thereafter, no control instruction regarding lighting / extinguishing of the light emitting member is accepted. For this reason, even if a user performs an erroneous operation or an unintended operation when a power failure occurs, the light emitting member does not turn off, and thus it is possible to reliably ensure illumination. In addition, it is possible to prevent a part of the light emitting members from being extinguished due to the occurrence of incoming processing or the like.

  Moreover, according to the structure of this invention, the subunit | mobile_unit is equipped with the illumination part which consists of high-intensity LED and a reflective member.

  FIG. 4 is a processing flow of the base unit 1 in preparation for the occurrence of an earthquake. The processing flow shown in FIG. 4 can be started at an arbitrary timing in a state where the power source of the base unit 1 is activated and communication with the Internet 62 is possible. After the start of this process, in step S110, the breaking news detection unit 11a determines whether or not the communication control unit 15 has received the emergency earthquake breaking news via the Internet 62 and the wired LAN 41.

  When it is determined that the earthquake early warning is not received, the process proceeds to step S110 again, and the detection process is repeated until the emergency earthquake early warning is detected. When the reception of the emergency earthquake bulletin is detected, the bulletin detection unit 11a performs processing for analyzing a message included in the emergency earthquake bulletin in step S120. Thereby, the predicted seismic intensity, the predicted arrival time of the main motion, and the like are calculated from various parameters included in the message.

  Next, the processing flow in the subunit | mobile_unit 2 is demonstrated using the flowchart of FIG. The processing flow shown in FIG. 5 can be started at an arbitrary timing when the handset 2 is in a standby state and wireless communication with the base unit 1 is possible. After the start of this process, the earthquake detection reception unit 21a determines whether or not an emergency earthquake warning detection notification has been received from the base unit 1 by the antenna device 26 in step S210.

  If it is determined that the detection notification has not been received, the process proceeds to step S210 again, and monitoring is continued until the detection notification is received. When the detection notification is received, the earthquake detection reception unit 21a gives a message indicating that the detection notification has been received to the light emission amount adjustment unit 21b.

  Next, in step S220, the control unit 21 reads out evacuation instruction voice data and image data recorded in advance in the memory 22 or the like. Based on the read data, the display unit 23 and the speaker 28 are used to output sound and images for evacuation instructions.

Next, in step S230, the light emission amount adjusting unit 21b instructs the light emitting unit 30 to turn on a part or all of the light emitting members included in the light emitting unit 30 with a predetermined light emission amount. Further, the lighting unit 80 is instructed to turn on the high-intensity LED 81. In step S240, the light emission amount adjusting unit 21b instructs the light emitting unit 30 and the illumination unit 80 to prohibit all the light emission control processes except the lighting process. Thereby, since both members perform only the lighting process, it is possible to prevent the members from being turned off due to an erroneous operation by the user.
