Description

  The present invention relates to an emergency disaster information receiver, and more particularly to an emergency disaster information receiver for receiving and notifying an earthquake early warning.

  An emergency disaster information receiver for receiving and notifying disaster information transmitted from a transmitting station when an emergency such as an earthquake occurs has been presented. For example, a disaster prevention radio (radio disaster management radio receiver with radio) or an emergency notification receiver that detects emergency earthquake warning chime sound from radio sound during standby and outputs radio sound from the speaker when detected Has been.

  Further, Patent Document 1 discloses a disaster prevention radio receiver that emits the contents of broadcast from a speaker when receiving an emergency earthquake warning in radio broadcast or when receiving a disaster prevention radio broadcast. This disaster prevention radio receiver detects that an earthquake early warning has been issued by detecting a chime sound transmitted together with the earthquake early warning.

  On the other hand, in terrestrial television broadcasting, emergency earthquake bulletins are transmitted in a form that is superimposed on the video and audio being broadcast. However, a delay occurs in encoding on the transmitter side, decoding on the receiver side, and the like, and there is a problem in quick reportability. In order to solve this problem, a method of transmitting emergency earthquake warning information using an AC (Auxiliary Channel) signal for transmitting additional information has been added to the ARIB (STD-B31) standard. According to this, the earthquake early warning is segment no. It is transmitted using 0 AC signal (carrier).

  For example, in Patent Document 2, when an earthquake early warning is issued from a broadcasting station using an AC signal, the fact is displayed on the display unit and emergency disaster information for generating an alarm sound according to a user setting is disclosed. A receiving device is disclosed. In addition, upon receiving the earthquake early warning, this emergency disaster information receiving device outputs a control signal for safely operating an external device such as an elevator from an output terminal, and also transmits an emergency broadcast to an external television receiving device. A command signal for receiving (power-on command, emergency broadcast channel selection command) is transmitted from the remote control transmitter.

  However, the method of detecting the chime sound of the earthquake early warning from the sound of the radio broadcast like the disaster prevention radio receiver described in Patent Document 1 is not related to the earthquake early warning because the analog sound is analyzed. Even in the case of sound, when a change in sound of a specific frequency is similar to that of a chime sound, a false detection may occur. Also, nationwide broadcasts also detect earthquake early warnings about areas that are not related to where you live (for example, if you live in Tokyo, you can also detect earthquake early warnings for Hokkaido). On the other hand, it may be confused as to whether it is an earthquake early warning for your area. And if such things continue, there is a risk that the attention to emergency earthquake warnings that are really relevant will be reduced.

The output unit 209 includes an audio processing unit 206, an image processing unit 210, an audio output unit 102, and a display unit 101.

  The one-seg broadcast signal input from the antenna 201 is subjected to processing such as decoding in a one-seg receiving unit (one-seg tuner) 202 configured by a module or the like, and information including video information, audio information, and AC signal information is TS ( (Transport Stream) signal information is output to the signal processing unit 203.

  The signal processing unit 203 extracts audio information from the TS signal information and outputs it to the audio processing unit 206, and extracts information such as area information and image information of the AC signal and outputs the information to the control unit 207.

  The control unit 207 performs control such as initialization of the one-segment receiving unit 202. In addition, when the information of the AC signal from the signal processing unit 203 is an emergency earthquake bulletin that covers the area of itself (emergency disaster information receiver 100), the control unit 207 sends text information (for example, to the image processing unit 210). , Emergency earthquake bulletin (Saitama Prefecture) is output to display characters on the display unit 101, and control is performed to output voice from the voice output unit 102 via the voice processing unit 206.

  The conversion table 301 is used to convert a bit number assigned to each area included in the earthquake early warning to data related to the area name. In the fixed character data table 302, fixed character data for outputting the warning contents of the earthquake early warning is written in advance. In the standard voice data table 303, standard voice data for voice output of alarm contents of emergency earthquake information is registered in advance.

  In the fixed character data table 302 and the fixed sound data table 303, one or a plurality of arbitrary data can be registered in advance by the user. In addition, voices recorded by the user may be registered in the standard voice data table 303. A number corresponding to the area where the emergency disaster information receiver 100 is installed is registered in the set area allocation bit number table 304, and is used to determine whether the area corresponds to the notification target area.

Can be used to determine the target area.

  FIG. 5 is a configuration diagram of emergency earthquake information 500 received by the one-segment receiving unit 202 via the antenna 201. The emergency earthquake information 500 includes video information 501, one-segment audio information 502, and AC signal information 503. The Japan Meteorological Agency announces information related to the earthquake early warning when there is a predicted earthquake occurrence area greater than the predetermined maximum seismic intensity. A transmitting station such as a television transmits the emergency earthquake information 500 included in the segment of the one-segment broadcasting signal based on this information.

  The AC carrier in the segment includes information on a region where a predetermined seismic intensity or more is predicted as AC signal information 503. Details will be described later with reference to FIG.

  FIG. 6 is a configuration diagram of TS signal information 600. The TS signal information 600 includes a sync byte 601, an indicator 602, and a length 603 in the header part. Further, the TS signal information 600 has AC signal information 604 in the data portion. The one-segment receiving unit 202 includes the AC signal information 503 of the emergency earthquake information 500 in the AC signal information 604 of the TS signal information 600 and transmits the AC signal information 503 to the signal processing unit 203. In this figure, an example in which AC signal information 503 is included in the data portion of TS signal information 600 is shown, but video information 501 or one-segment audio information 502 may be included as the data portion. In this case, the one seg receiving unit 202 can transmit the video information 501 or the one seg audio information 502 to the signal processing unit 203 in association with the AC signal information 503 of the other TS signal information 600.

  FIG. 7 is a configuration diagram of the AC signal information 503 and 604. The AC signal information 503 and 604 includes a configuration identification 701, a start / end flag 702, a signal identification 703, a current time 704, a page type 705, and earthquake motion information 706. Information included in AC signal information 503 and 604 is defined in ARIB STD-B31, and other information can be included as appropriate.

  Hereinafter, each piece of information included in the AC signal information will be described in accordance with the format of ARIB STD-B31. The configuration identification 701 is information indicating whether the AC signal information is transmission of earthquake motion warning information. Since the AC signal information itself is used for transmitting additional information in addition to the earthquake motion warning, it is determined by this configuration identification 701 whether the AC signal information is information related to an earthquake. The start / end flag 702 is information indicating the start or end of transmission of earthquake motion warning information. The signal identification 703 is information representing the type of detailed earthquake motion warning information. Current time 704 is current time information to which earthquake motion warning information is sent. The earthquake motion information 706 is information indicating a target area of the earthquake motion warning, which is an area where an earthquake of a predetermined seismic intensity or higher is predicted, which is transmitted when the page type 705 is “0”. In the present embodiment, a case where the page type 705 is “0” will be described.

The seismic motion information 706 indicating the target area of the seismic motion warning is assigned to the 56th to 111th bits of the AC signal information 503 and 604, and one area of information is assigned to each bit. When the bit value is “1”, the area does not include the target area for the earthquake motion warning, and when the bit value is “0”, the area includes the target area for the earthquake motion warning. For example, when “B ₆₉ ” (hereinafter, “B” represents a bit value and a subscript represents a bit number) is “0”, it indicates that Saitama Prefecture is included in the target area of the earthquake motion warning.

  Next, processing at power-on will be described. When the power is turned on, the control unit 207 performs initial setting of the one-segment receiving unit 202, initial setting of the signal processing unit 203, initial setting of the display unit 101, and the like. Thereafter, the user sets the one-seg reception channel and the area to be installed by using the operation buttons (channel selection buttons) 105, 106 and the like.

  Specifically, the user inputs an area name where the emergency disaster information receiver 100 is installed from the input unit 103 according to the area name character data 402 displayed on the display unit 101. As the area name, for example, a prefecture name is input. The control unit 207 refers to the conversion table 301, obtains the assigned bit number 401 corresponding to the input region name, and stores the obtained assigned bit number 401 in the set region assigned bit number table 304 in the control storage unit 208. .

  The user operates the input unit 103 to select a one-segment broadcasting station to be received (for example, a broadcasting station with a good radio wave condition or a broadcasting station corresponding to a region), thereby determining the one-segment reception channel. The control unit 207 instructs the one-segment receiving unit 202 through I2C (Inter Integrated Circuit) to tune the determined reception channel. Thereafter, the user enters a standby state (speaker output or character display off state) by a setting completion operation by the user.

  Next, processing of the signal processing unit 203 will be described. FIG. 8 is an explanatory diagram of a flowchart of the signal processing unit 203. When the processing is started, the signal processing unit 203 performs initial setting in response to an instruction from the control unit 207 through the UART (Universal Asynchronous Receiver Transmitter), and performs emergency earthquake warning using the AC signal of the one-segment reception unit 202. Processing of TS signals necessary for detection is started.

  In step S <b> 100, the signal processing unit 203 determines whether an AC header indicating that AC signal information is included in the TS signal information 600 output from the one-segment receiving unit 202 is transmitted. For example, the AC header has 1 byte in the sync byte 601, 1 byte in the indicator 602, and 2 bytes in the length 603. The sync byte 601 represents AC signal information if 0xB0 (hexadecimal B0), and other video and audio information if 0x47. The indicator 602 indicates a start packet if 0x80, an end packet if 0x20, and an intermediate packet if 0x40. The length 603 represents the remaining number of bytes in hexadecimal. One packet is composed of 188 bytes including the header part and the data part, and 0x00 is continuously transmitted until the part less than 188 bytes reaches 188 bytes.

  When the sync byte 601 is 0xB0, the signal processing unit 203 proceeds to the process of step S110 when it detects the header part as an AC header, and repeats the process of step S100 when it is not detected.

  In step S <b> 110, the signal processing unit 203 takes in data (AC signal information 604) following the AC header of the TS signal information 600 and stores it in the signal processing storage unit 204 such as a FIFO memory in the signal processing unit 203.

  In step S120, the signal processing unit 203 determines whether the last byte of the AC signal information 604 has been captured. The signal processing unit 203 proceeds to the process of step S130 if the last byte has been fetched, and returns to the process of step S110 if not fetched. In the present embodiment, the 184th byte of data is the last byte, and the number of bytes represented by 2 bytes of length 603 is valid data as the AC signal information 604.

  In step S <b> 130, the signal processing unit 203 converts the format of the remaining data excluding the header of the TS signal information 600 into a format for sending to the control unit 207. When the 1-bit data of the AC signal information 604 from the one-segment receiving unit 202 is converted into 1-byte data (hexadecimal 0xFF if binary 0b1 and 0x00 if 0b0), the signal processing unit 203 converts the format of the data from 1 byte to 1 bit (hexadecimal 0xFF is binary 0b1 and 0x00 is 0b0). Data whose format has been converted for each byte is deleted from the signal processing storage unit 204.

  In step S140, the signal processing unit 203 outputs the format-converted AC signal information 604 data from the UART 1 to the control unit 207 every 8 bits. When the data output ends, the process returns to the AC header detection process in step S100.

  Although UART1 is used here, another communication method such as 8-bit parallel communication can be used instead.

  FIG. 9 is a flowchart for explaining the control unit 207. The control unit 207 outputs warning contents (emergency warning information) of the emergency earthquake warning according to this flow. When the control unit 207 enters a standby state (speaker output or character display off state) by a setting completion operation by the user, the control unit 207 starts detection processing of a signal transmitted by the signal processing unit 203.

  In step S200, the control unit 207 determines whether the AC signal information 604 has been received from the signal processing unit 203 through UART1. If AC signal information 604 is received, the process proceeds to step S210. If not received, the process of step S200 is repeated.

  In step S <b> 210, the control unit 207 takes in the AC signal information 604 received from the UART 1 and stores it in the control storage unit 208 inside the microcomputer 205.

  In step S220, the control unit 207 determines whether or not the last byte of the AC signal information 604 has been captured. If the last byte has been fetched, the process proceeds to step S230, and if not, the process returns to step S210. The final byte is determined by determining the data amount of the packet in advance and determining whether the number of received bytes matches the predetermined data amount of the packet, or the transmission byte at the head of the data transmitted from the signal processing unit 203 This is performed by a method of determining whether or not the number of received bytes matches the number of transmitted bytes in the header by attaching a header that indicates the number.

  In step S230, the control unit 207 determines whether the received AC signal information 604 is an emergency earthquake bulletin. If it is an emergency earthquake warning, the process proceeds to step S240. If not, the control unit 207 proceeds to the determination process in step S200. Return.

Method for determining the earthquake early warning, in the form of data of ARIB STD-B31, the control unit 207, among the _{B 0} 204-bit data _{B 203,} from _{B 1 B 3} (Configuration identification 701) is a binary number It is stipulated that when it is 0b001 or 0b110, it is determined that it is an emergency earthquake warning, and otherwise it is determined that it is not an emergency earthquake warning.

  In step S240, the control unit 207 further determines whether or not the area of the emergency (emergency disaster information receiver 100) that is set in advance is included in the target area of the earthquake early warning, and receives itself (emergency disaster information reception). If the area of the machine 100) is included, the process proceeds to step S250 (first disaster prevention alarm process), and if not included, the process proceeds to step S260 (second disaster prevention alarm process).

Method for determining the target area of the earthquake early warning, the data format of the ARIB _STD-B31, the data from _{B 56 B 111} (ground motion information 706), each one region is assigned to one bit, the bit value It is stipulated that “0” corresponds to the target area, and “1” does not correspond to the target area. The control unit 207 looks at the bit value corresponding to the preset installation area information of itself (emergency disaster information receiver 100), and if “0”, it is included in the target area, and if “1”, it is included in the target area. It is determined that it is not included.

A specific example will be described with reference to FIG. For example, if the area set by the user at the initial setting is Saitama prefecture, “69”, which is the assigned bit number 401 corresponding to “Saitama prefecture”, is registered in advance in the set area assigned bit number table 304. Yes. The control unit 207 refers to the set area allocation bit number table 304 and confirms the B ₆₉ data of the earthquake motion information 706 because the registered data is “69”. If the data of B ₆₉ is “0”, the control unit 207 determines that the target area is included. If the data of B ₆₉ is “1”, the control unit 207 determines that the data is not included in the target area.

  Returning to FIG. 9, in step S <b> 250, the control unit 207 outputs the warning content of the emergency earthquake warning. For example, in the case of character display output, the control unit 207 obtains fixed character data “Earthquake Early Warning” indicating a warning from the fixed character data table 302 of the control storage unit 208. In addition, the control unit 207 refers to the conversion table 301 and acquires the region name character data 402 “Saitama Prefecture” corresponding to the data “69” of the set region allocation bit number table 304 in the data string 415. Then, the control unit 207 transmits character data of “Earthquake Early Warning” and “Saitama Prefecture” and a display output instruction to the image processing unit 210 via UART (UART 2 in the block diagram). The image processing unit 210 causes the display unit 101 to display these character data received from the control unit 207. Thereby, for example, the characters “Earthquake Early Warning Saitama” can be scroll-displayed.

  In step S250, one or a plurality of area names that are different from the area of the earthquake disaster information receiver 100 in the target area of the earthquake motion information are also displayed on the display unit 101 as reference information or displayed on the audio output unit 102. You may make it output.

  In step S260, the control unit 207 notifies information related to the emergency earthquake bulletin in an area different from the area where the self (emergency disaster information receiver 100) is installed. For example, in the case of character display output, the control unit 207 identifies a bit indicating a target area of earthquake motion information among bits allocated to an area different from the area of itself (emergency disaster information receiver 100), One or a plurality of area name character data 402 corresponding to the specified bit is acquired from the conversion table 301. In addition, the control unit 207 acquires fixed character data indicating an alarm from the fixed character data table 302 of the control storage unit 208. The control unit 207 transmits the acquired area name character data, fixed character data, and image output instruction to the image processing unit 210. Then, the image processing unit 210 can continuously display the area name character data and the fixed character data from the display unit 101.

  In step S250 and step S260, it can be arbitrarily determined in advance which of the character display output and the sound output is used. In addition, at the time of initial setting, if the area of itself (emergency disaster information receiver 100) indicated by the number in the setting area allocation bit number table 304 is not included in the target area of the earthquake motion information of the emergency earthquake warning, an alarm output “is performed”. It is also possible to select “No” or “No”. When the user selects the alarm output “not” when the set area code of the user (emergency disaster information receiver 100) does not correspond to the target area of the earthquake motion information, the process of step S260 is omitted, and the user (emergency disaster information) The information receiver 100) can return to the standby state and maintain the standby state without outputting the earthquake early warning that is not included in the target area.

  When the alarm output is finished after a predetermined time has elapsed, the process enters a standby state (voice output or character display off state), and returns to the determination in step S200.

  In step S250, if the control unit 207 determines that the target area is included, the control unit 207 flashes a part or the whole of the display unit 101 (repeats all lighting and all extinction in a short time), and then the character is changed. Display can be performed (first output operation). In addition, when it is not included in the target area, the control unit 207 displays characters as they are without flashing the display unit 101 in step S260 (second output operation), and the notification level is set higher than the first output operation. Can be lowered. Thereby, it is possible to change the notification level according to the degree of urgency and to output a warning by a two-stage output operation.

  Further, at the time of initial setting, when the area of itself (emergency disaster information receiver 100) indicated by the number in the set area allocation bit number table 304 is not included in the target area of the earthquake motion information of the emergency earthquake warning, an alarm output “is performed”. ”Is set, if the area of itself (emergency disaster information receiver 100) indicated by the number in the set area allocation bit number table 304 is included in the target area of the seismic motion information, the control unit 207 relates to the volume setting. First, the sound is output at the maximum volume (first output operation), and if it is not included in the target area, the sound can be output at the normal volume according to the volume setting (second output operation). Thereby, it is possible to change the notification level according to the degree of urgency and to output a warning by a two-stage output operation.

  Next, another method for outputting the warning contents of the earthquake early warning will be described. The emergency disaster information receiver 100 can output the warning contents of the emergency earthquake warning with sound fixed to the device.

  In the case of fixed sound output, in step S250, the control unit 207 acquires the fixed sound data indicating the alarm from the fixed sound data table 303 of the control storage unit 208. In addition, the control unit 207 refers to the conversion table 301 and acquires the area name audio data 403 indicating “Saitama Prefecture” corresponding to the data “69” of the set area allocation bit number table 304 in the data string 415. Then, the control unit 207 transmits the standard audio data and the area name audio data to the audio processing unit 206 together with the audio output instruction. The audio processing unit 206 causes the audio output unit 102 to output these audio data received from the control unit 207. As a result, when emergency earthquake information is received, disaster prevention alarm information can be reliably output even if the audio signal is transmitted after a delay from the transmitting station or if it takes time to demodulate or decode the audio signal. be able to.

  Further, in step S260, the control unit 207 acquires the fixed sound data indicating that the alarm is generated from the fixed sound data table 303 of the control storage unit 208. The control unit 207 acquires the region name audio data 403 of the region that is the target region of the seismic motion information among the regions different from the region of the own (emergency disaster information receiver 100), and the standard audio data, the region name audio data, and the audio An output instruction is transmitted to the audio processing unit 206. Then, the voice processing unit 206 outputs a voice for notifying the alarm by the voice output unit 102.

  Next, another method for outputting the warning contents of the earthquake early warning will be described. The emergency disaster information receiver 100 can output the warning contents of the emergency earthquake warning as voice.

  For example, when transmitting the AC signal information 503 to the signal processing unit 203, the one-seg receiving unit 202 transmits the one-seg audio information 502 in association with the AC signal information 503. The signal processing unit 203 stores the one-segment audio information 502 in the signal processing storage unit 204. If the control unit 207 determines that the installation area information of itself (emergency disaster information receiver 100) is the target area of the earthquake motion information in step S240, in step S250, the control unit 207 and the signal processing unit 203 and the audio so as to reproduce the one-segment audio. An instruction is issued to the processing unit 206. The signal processing unit 203 transmits the one-segment audio information 502 to the audio processing unit 206. As a result, it is possible to output a one-segment audio from the audio output unit 102 or to operate an alarm output.

  Next, another method for outputting the warning contents of the earthquake early warning will be described. The emergency disaster information receiver 100 can display video information included in the earthquake early warning.

  For example, the one seg receiving unit 202 includes the video information 501 as data of the TS signal information 600 and transmits the video information 501 in association with the AC signal information 604. If the signal processing unit 203 determines in step S100 that the video information 501 associated with the other AC signal information 604 has been received even if the AC header is not detected in the TS signal information 600, the signal processing unit 203 performs step S110. Proceed to The signal processing unit 203 captures the video information 501 in step S110 and transmits it to the control unit 207 in step S140. If the control unit 207 determines in step S200 that the video information 501 associated with the AC signal information has been received, the control unit 207 captures data in step S210. The control unit 207 proceeds to step S250 or step S260 according to the determination result using the AC signal information in step S230 and step S240. In step S250, the control unit 207 transmits the video information 501 to the image processing unit 210 together with an output instruction. The image processing unit 210 displays the video information 501 from the display unit 101. In step S260, the control unit 207 transmits the video information 501 to the image processing unit 210 together with an output instruction. The image processing unit 210 displays the video information 501 from the display unit 101. In the case of an emergency earthquake warning that does not include the set area code of itself (emergency disaster information receiver 100) in the target area of the seismic motion information at the time of initial setting, if the alarm output “No” is selected, control is performed. The unit 207 may not output the video information in step S260.

  In addition, the output method of the disaster prevention alarm information in receiving emergency earthquake information can be applied in combination as appropriate.

[Second Embodiment]
Next, a second embodiment of the emergency disaster information receiver 100 will be described. The emergency disaster information receiver 100 can output a signal for controlling an external device when emergency earthquake warning information is detected together with or in place of voice output or character display. The emergency disaster information receiver 100 has a control output unit for controlling contacts such as relays and transmitting voice data and character data to the output unit 209. The control unit 207 can output a control signal from the control output unit to control an external audio device, an alarm lamp, and the like. The emergency disaster information receiver 100 can use an indoor broadcast device as an external device, and can cause the indoor broadcast device to broadcast disaster prevention alarm information according to the content of the emergency earthquake warning. In this case, the emergency disaster information receiver 100 may send only a start signal, and the indoor broadcasting device may output preset audio data or character data according to the type of the start signal. For example, an indoor broadcasting device outputs audio data from an indoor speaker or displays character data on an appropriate display unit. In addition to these, the control unit 207 can output a control signal to control an appropriate external device. In addition, this embodiment can also be performed in combination with 1st embodiment.

  As described above, according to the present embodiment, the emergency earthquake warning based on the AC signal of the one-segment broadcasting is a dedicated signal, and is more accurate than the chime sound of the radio emergency earthquake warning that is a notification sound for humans. An emergency disaster information receiver with few false detections can be configured. In addition, since the AC signal includes information on the area targeted for the earthquake early warning, it is possible to determine whether the installation location is included in the area targeted for the notification, and to exclude the unrelated rapid reports from the output target. In addition, since the earthquake early warning by one-seg broadcasting uses an AC signal with less delay compared to video and audio of television broadcasting, it is possible to transmit emergency earthquake early warning earlier than video and audio flowing on the television.

  As mentioned above, although embodiment of this invention was described, this invention is not limited by this embodiment, It can implement with a various form.

  For example, in the present embodiment, the signal processing unit 203 and the audio processing unit 206 are configured as processing units different from the control unit 207 of the microcomputer 205, but an FPGA (field-programmable gate array), a DSP (Digital Signal Processor), and the like. Any device capable of high-speed processing can be configured as one processing unit.

  The processing in the embodiment of the present invention is applied to various apparatuses as a program that can be realized by a computer, for example, written in a storage medium such as a magnetic disk, an optical disk, or a semiconductor memory, or transmitted through a communication medium. It is also possible to apply to various devices. As described above, by storing the processes described in the present embodiment in a desired storage medium and causing the program to be executed by another computer or the like, it is possible to obtain the same operational effects as when the apparatus of the present embodiment is used. The computer is not limited to the computer built in the apparatus described in the present embodiment, but can read a program stored in a storage medium and can perform a control operation according to the read program. Includes any computer equipped with a computing device.
