Description

  The present invention relates to an emergency information notification system mounted on a shared vehicle.

  For example, a “fare display device” as disclosed in Patent Document 1 below is mounted on a shared vehicle such as a route bus or a one-man train. In this "fare display device", a fare table consisting of the number of the numbered ticket issued from the numbered ticket issuing machine at the time of boarding and each fare corresponding to these numbers is displayed on both screens on a display device with a two-screen configuration. It is displayed in a list form, a fare table is displayed on one screen, and information contents other than the fare table are displayed on the other screen. This makes it possible to provide passengers with information content other than the fare while shortening the fare confirmation time by the passenger.

  The “Earthquake Early Warning” described in the claims means that the JMA analyzes the seismic data (mainly P waves) captured by the seismometer at the observation point close to the epicenter immediately after the occurrence of the earthquake. The location and magnitude (magnitude) of the earthquake is immediately estimated, and based on this, the arrival time and seismic intensity of the main motion (mainly S wave) in each region are estimated, and several to several tens of seconds before the main motion arrives. It is information announced from. The Japan Broadcasting Corporation and private broadcasting stations that received this earthquake early warning from the Japan Meteorological Agency, etc., broadcast with a predetermined chime sound at the beginning, Corresponds to “broadcast wave including information”

  In addition, the “emergency warning broadcast” described in the claims is broadcast by the Japan Broadcasting Corporation or a private broadcasting station when a large-scale disaster such as an earthquake occurs or when a tsunami warning is announced. This is a broadcast in which a predetermined emergency warning signal for automatically turning on a switch for a television or radio in a standby state is added to the beginning of a broadcast wave. The emergency warning signal includes a first type start signal, a second type start signal, and an end signal. An audio broadcast wave that is broadcast with the first type start signal and the second type start signal added to the beginning is claimed. Corresponds to “Broadcast wave of emergency warning broadcast” described in the above section. The type 1 start signal is transmitted when a warning of a large-scale earthquake is announced or when an evacuation order is issued from the head of a local government based on the Disaster Countermeasures Basic Act. The second type start signal is transmitted when a tsunami warning is announced.

  In the present invention, when receiving the broadcast wave including the sound information of the emergency earthquake warning for the region or the region where the traveling route of the riding vehicle is included, the reception device outputs the sound information of the emergency earthquake warning, The voice announcement based on the voice information input from the receiving device is output to the passenger vehicle so that the crew and passengers of the passenger vehicle can listen. That is, the earthquake early warning is directly received from the broadcast wave transmitted from the broadcasting station without going through the network infrastructure such as the Internet, and the voice announcement is output to the passenger vehicle and passengers in the passenger vehicle so that they can be heard. As a result, an emergency earthquake warning voice announcement is output to the passenger vehicle almost simultaneously with the earthquake early warning broadcast, so there is no delay time that may occur when the emergency earthquake warning is obtained via a computer network, and the crew member of the passenger vehicle. And it is possible to notify the earthquake early warning to passengers in real time. Therefore, the emergency earthquake bulletin can be promptly notified to the passenger by voice announcement without interfering with the fare display.

  In the present invention, the emergency information output device includes a predetermined message selected by a selection switch from a plurality of predetermined messages including at least emergency earthquake information including characters and / or figures corresponding to voice information of the earthquake early warning. The display information control device that has input the predetermined message outputs (2) the list of fare display so that the predetermined message is displayed in place of the display area without the amount display in the (1) fare display list. The in-vehicle information display device is controlled so that the display area is reduced and displayed in an empty display area, or (3) it is displayed at a time different from the fare display list display time. In other words, the predetermined message selected by the selection switch is (1) instead of the display area without the amount display in the list of fare display, or (2) the display area of the fare display list reduced to an empty display area, or (3) Displayed on the in-vehicle information display device at a time different from the list display time of the fare display. Thereby, even if the predetermined message selected by the selection switch is output to the in-vehicle information display device displaying the fare, the predetermined message is displayed in the display area with the amount display in the list of the fare display. Therefore, the predetermined message does not get in the way when confirming the payment amount by the passenger. Therefore, the emergency earthquake warning can be promptly notified to the passenger without disturbing the fare display by the in-vehicle information display device following the voice announcement.

  As described above, in the present invention, an emergency earthquake warning voice announcement is output to the passenger vehicle as an initial motion almost simultaneously with the broadcast of the earthquake early warning, and then the predetermined message is not disturbed by the operation of the selection switch. Output to the information display device. Therefore, it is possible to promptly notify the passengers of the earthquake early warning without disturbing the fare display.

It can be output arbitrarily inside or outside the car.

[Configuration of fare display device 20]
Next, the structure of the fare display device 20 will be described with reference to FIGS. 1, 2, 4 and 5. FIG. FIG. 4 is an explanatory diagram showing a display example by the liquid crystal display unit 26 constituting the fare display device 20. FIG. 5 is an explanatory diagram showing an example of a display area by the liquid crystal display unit 26.

  As shown in FIG. 2, the fare display device 20 provided in front of the inside of the route bus 100 and above the exit 100b includes an MPU 21, a system memory 23, a data memory 24, a GPU 25, a liquid crystal display unit as shown in FIG. 26, an I / O interface 27, and the like, and are housed in a thin box-like casing except for the liquid crystal display unit 26.

  As shown in FIG. 1, the MPU 21 is an arithmetic processing unit that controls the fare display device 20, and a system memory 23, a data memory 24, a GPU 25, and an I / O interface via a signal bus 22 such as a system bus or a data bus. 27 etc.

  The system memory 23 is a semiconductor storage device connected to the signal bus 22 and constitutes a main storage space used by the MPU 21. In this embodiment, the program area is composed of a ROM and a DRAM allocated to a work area and a data area. The ROM stores a system program (so-called OS) 23a, a fare display program 23b, an emergency information reading program 23c, an emergency information output program 23d, a screen display control program 23e, a voice output control program 23f, and the like.

  The data memory 24 is also a semiconductor storage device connected to the signal bus 22 and constitutes an auxiliary storage space accessible by the MPU 21 by, for example, an electrically erasable nonvolatile memory (for example, an EEPROM such as a flash memory). ing. Since the nonvolatile memory keeps the stored data regardless of whether or not power is supplied, in this embodiment, various data such as operation information data 24a, fare information data 24b, content data 24c, and emergency information data 24d are stored. doing. The emergency information data 24d is a group of emergency messages to be described later. The content data refers to data that constitutes information content. The information content is hereinafter expressed as “content”.

  A GPU (Graphics Processing Unit) 25 is an image processing apparatus that specializes in processing image data. In this embodiment, the GPU 25 performs predetermined screen display control in cooperation with the execution of the screen display control program 23e by the MPU 21. . The GPU 25 is connected to a dual port memory (VRAM) 25 v having specifications suitable for the liquid crystal display unit 26, and display data output to the liquid crystal display unit 26 is written and read out. Note that a graphic accelerator, a graphic controller, or the like may be used instead of the GPU 25 as long as the image display of the liquid crystal display unit 26 can be controlled.

  As shown in FIG. 4, the liquid crystal display unit 26 is configured to cover almost the entire surface of the thin box-like housing, and in this embodiment, a liquid crystal display device that enables left and right two-screen display is used. It has been. The liquid crystal display unit 26 is connected to the GPU 25 via the above-described dual port memory 25v. In this embodiment, the display area of the dual port memory 25v is divided into two and assigned to the left screen 26a and the right screen 26b. Display control.

  For example, when displaying the fare, which is a basic function of the fare display device 20, the MPU 21 displays the amount of money for the numbered ticket numbers 1 to 24 shown in FIG. 4 on the liquid crystal display unit 26 by executing the fare display program 23b. . For this reason, in the GPU 25, in cooperation with the execution of the screen display control program 23e by the MPU 21, the numbered ticket numbers 1 to 4, 9 to 12, and 17 to 20 among the fare tables Da and Db divided into two. The fare table Da displaying the amount is displayed on the left screen 26a, and the right fare table Db displaying the amount for the numbered ticket numbers 5 to 8, 13 to 16, and 21 to 24 is displayed on the right screen 26b. Above the fare table Da on the left side, “Gifu Civic Gymnasium” is displayed on the left screen 26a as the name of the stop that is scheduled to stop next, and at the next stop above the fare table Db on the right side. “I'll stop.” And the like are displayed on the right screen 26b.

  That is, as shown in FIG. 5A, the left screen 26a and the right screen 26b are not the whole screen αa and αb, but a part of the upper screen (hereinafter referred to as “upper region”) βa and βb. The above range is set as a display area for fare display, and other information is displayed in these upper areas βa and βb. In the example of FIG. 4, “in front of Gifu Civic Gymnasium” (the name of the stop that is scheduled to stop next) is displayed in the upper area βa of the left screen 26a, and “continue in the upper area βb of the right screen 26b. ”(That it is scheduled to stop at the next stop), and these display controls are performed by the screen display control program 23e.

  Although a specific example is not shown in the display example shown in FIG. 4, as shown in FIG. 5 (A), other parts of the lower part of the screen (hereinafter referred to as “lower region”) γa, γb Information can be displayed, and these display controls are also performed by the screen display control program 23e. Further, as shown in the right side screen 26b of FIG. 6, the divided display areas (each of the left, right, upper, and lower sides) are divided even when the vertical line δv is divided into left and right parts and the horizontal line δh is divided into upper and lower parts. Different contents (for example, commercials, weather forecasts, etc.) can be displayed for each display area, and these are also controlled by the screen display control program 23e.

  As shown in FIG. 5 (B), when a wide-type single-screen liquid crystal display unit 26 ′ constitutes a fare display device 20 ′ instead of the liquid crystal display unit 26, the liquid crystal display unit Since 26 'is horizontally long, for example, the right and left sides are divided into two around the vertical line δv with respect to the entire screen α, and different contents (for example, commercials, weather forecasts, etc.) are displayed in the left and right display areas. As described above, display control can be performed by the screen display control program 23e. Further, similarly to the liquid crystal display unit 26 shown in FIG. 5A, the upper region and the lower region may be divided into upper and lower parts by a horizontal line δh.

  In addition, as shown in FIG. 5B, a closed region ε is formed by an arbitrary shape (rectangular shape, polygonal shape, circular shape, elliptical shape, etc.), and content different from the region around the region ε is formed in the region ε. Display control may be performed by the screen display control program 23e. Furthermore, display control can be performed by the screen display control program 23e so that such an area ε is appropriately moved and displayed in the entire screen α (area ε ′). Such image display control can be similarly applied to the left and right screens 26a and 26b of the liquid crystal display unit 26 having a two-screen configuration shown in FIG.

  Here, returning to the display example shown in FIG. 4, the fare display program 23b changes and displays the display content of the right screen 26b at predetermined time intervals. For this reason, as shown in FIG. 4, for example, the screen display control program 23e displays the fare table Db and the like for 10 seconds, and then displays a display Ca to refrain from using the mobile phone for 5 seconds, and then displays the connection information. After the display Cb is displayed for 5 seconds, the IC card commercial display Cc is further displayed for 5 seconds, and then the fare table Db is displayed again for 10 seconds. By repeating this (Db-> Ca-> Cb-> Cc-> Db-> Cd-> Ce-> Cf-> Db-> Ca-> Cb-> ...), various contents can be shown to the passenger on the same right screen 26b.

  As described above, since the liquid crystal display unit 26 is composed of two left and right screens, the left screen 26a is fixed and displayed on the fare table Da (the left screen 26a is a fixed screen), and is continuously displayed every predetermined time. The display control by the GPU 25 is performed so that the fare table Db is displayed on the right screen 26b with the contents Ca to Cf changing in a predetermined time period (the right screen 26b is a variable screen). Each content Ca to Cf displayed here is content data 24c stored in the data memory 24, and is appropriately read from the data memory 24 by the fare display program 23b. The installation position of the fare display device 20 and the fixed screen and the variable screen may be set to be reversed left and right (the left screen 26a is the variable screen and the right screen 26b is the fixed screen).

  In this embodiment, as will be described later, screen display control is also performed by the screen display control program 23e for an emergency message (predetermined message) displayed on the liquid crystal display unit 26 in response to a command sent from the receiving device 30. Is called.

  For example, instead of the contents Ca to Cf displayed at predetermined time intervals on the right screen 26b of the liquid crystal display unit 26, screen display control is performed so as to display the contents of an emergency message as described later. In addition, as shown in the range of βa, βb, γa, γb shown in FIG. 5A, or the range of ε and ε ′ shown in FIG. The screen display control is performed so as to display the contents of. Thereby, since both the fare display such as the fare schedule Da, Db and the emergency message are displayed on the liquid crystal display unit 26, the contents of the emergency message can be notified to the passenger. Such a display example can correspond to “display at a time different from the list display time of the fare display” described in the claims.

  Usually, since the amount display starts from the young (small) number of the numbered ticket number, for example, the first half 1 to 24 of the numbered ticket number is the left fare table Da ′, and the second half 25 to 48 of the numbered ticket number is the right side. The configuration of the fare schedules Da and Db is changed as shown in FIG. In such fare tables Da ′ and Db ′, the amount corresponding to the numbered ticket numbers 25 to 48 of the fare table Db ′ is displayed, such as a route bus 100 having a stop number of 24 or less after leaving the first station. If it is not necessary (blank), screen display control is performed so that the contents of the emergency message are displayed in place of the fare table Db ′. As a result, an emergency message is always displayed on the right screen 26b of the liquid crystal display unit 26 instead of the fare table Db, so that the emergency message is notified to the passenger without affecting the fare display required by the passenger. can do.

  Furthermore, if the content displayed as an emergency message is a predetermined logo mark or pictogram expressed in figures or illustrations (see Fig. 8 (B)), it corresponds to the numbered ticket number in the fare tables Da and Db. Although there is no display of the charge to be displayed, a screen is displayed so that such a logo mark or the like is displayed in the range of the display frame including the numbered ticket number (for example, the numbered numbers 13 to 16 and 21 to 24 shown in FIG. 4). Control is performed. When the size of the display frame range (display area) is smaller than the display size of a logo mark or the like, a logo mark or the like deformed by reduction or the like according to the display area is displayed. Thereby, an urgent message can be displayed without affecting the fare display of the fare table Da, Db or the like. Such a display example may correspond to “display in place of a display area without a monetary amount display in a list of fare display” described in the claims.

  In addition, a fare display in which the configuration of the fare schedule Da, Db and the like is changed so as to fit in the entire left screen 26a of the liquid crystal display unit 26 that is always displayed is displayed on the left screen 26a, and the right screen 26b that does not display the fare display. Screen display control is performed to display an emergency message. As a result, all of the fare display is always displayed on the left screen 26a, and the urgent message is continuously displayed on the right screen 26b. Therefore, the emergency display can be made without affecting the fare display of the fare schedule Da, Db, etc. A message can be displayed.

  In addition, screen display control is performed so that the fare display of the fare schedule Da, Db, etc. is reduced and displayed, and an urgent message is displayed in the empty display area. For example, as shown in the right screen 26b of FIG. 5A, a part of the entire screen αb divided into four by the vertical line δv and the horizontal line δh (for example, the upper left area) is reduced fare table Da, The display area of Db is used, and the remainder (for example, the lower left and upper right and lower areas) is used as the emergency message display area. Thereby, although the fare display of the fare schedule Da, Db, etc. is reduced, since both the fare display and the emergency message are displayed on the liquid crystal display unit 26, the fare display of the fare schedule Da, Db, etc. is not affected. , Emergency messages can be displayed. Such a display example can correspond to “reducing the list display area of the fare display and displaying it in an empty display area” described in the claims.

  As shown in FIG. 1, the I / O interface 27 includes an input / output device such as a receiving device 30, a stop display control device 41, a destination display device 51, an on / off display device 53, a speech synthesizer 60, an amplifying device 70, and the MPU 21. An input / output interface device that mediates serial (USB standard, etc.) or parallel (IEEE1284 standard, etc.) data exchange with the signal bus 22. Although not shown in the drawing, hardware settings and software settings of the fare display device 20 can be made by connecting input devices such as a keyboard and a mouse to the I / O interface 27 via a serial connection according to the USB standard. I have to.

  By configuring the fare display device 20 in this way, the MPU 21 receives a command transmitted from the receiving device 30 described below under the management of the system program 23a, and receives a fare display program 23b as an application program. An emergency information reading program 23c, an emergency information output program 23d, a screen display control program 23e, and a voice output control program 23f are executed.

  In the present embodiment, the MPU 21, the system memory 23, and the like are configured by individual semiconductor devices, but may be configured by a one-chip IC, a hybrid IC, or the like, such as an application specific IC (ASIC). . Further, the ROM and data memory 24 of the system memory 23 may be replaced with a magnetic disk storage device (HDD).

[Configuration of Receiving Device 30]
Then, the structure of the receiver 30 is demonstrated based on FIGS. 1-3. FIG. 3 is an explanatory diagram illustrating an example of an external configuration of the receiving device 30.
As shown in FIGS. 2 and 3, the receiving device 30 is provided in the vicinity of the driver's seat 100 d of the route bus 100 and within the reach of the crew. The receiving device 30 includes a rectangular box-shaped casing 30a having an operation panel 30b, a display unit 32, and the like. As shown in FIG. 1, a control unit 31, a display unit 32, an operation unit 33, a setting unit 34, The receiving unit 35, the amplifying unit 37, the built-in speaker 38, the external antenna 39, and the like are included.

  The control unit 31 is an information processing device that performs overall control related to the receiving device 30, and is realized by, for example, a one-chip microcomputer that includes a memory (EEPROM, DRAM, etc.) necessary for the control and an input / output interface. In addition, a display unit 32, an operation unit 33, a setting unit 34, a reception unit 35, and an amplification unit 37 are connected to the input / output interface. In the present embodiment, the emergency information notification program 31a is stored in the EEPROM of the control unit 31, and predetermined setting information is rewritable by the operation unit 33 and the setting unit 34 in the predetermined hardware setting area. It is remembered. As will be described later, when the control unit 31 executes the emergency information notification program 31a, an emergency information notification function unique to the present system is realized.

  As shown in FIGS. 1 and 3, the display unit 32 is, for example, a dot display type liquid crystal display device, and is configured to be connected to the control unit 31 so as to be able to display the operation state and the setting state of the reception device 30. Yes. As an operation state, for example, “Receiving emergency earthquake warning” displayed when the receiving unit 35 receives an emergency earthquake warning, or “Receiving emergency warning broadcast” displayed when the receiving unit 35 receives an emergency warning broadcast. Middle ”and“ reception test in progress ”displayed during the reception test. As an example of the setting state, the reception unit 35 displays the reception frequency “XX. "MHz" (○ is a number) and the name and abbreviation of the currently selected broadcasting station are displayed.

  The operation unit 33 outputs input information corresponding to operation inputs of a plurality of push button switches (hereinafter referred to as “switches”) to the control unit 31. For example, as illustrated in FIG. 3, in the vicinity of the display unit 32. Each of the switches 33a to 33g provided at seven locations in the operation panel 30b located at the same position, its state holding circuit and the like. In the present embodiment, it is assumed that these switches 33a to 33g are operated by a crew member or the like.

  The switches 33a and 33b are tuning switches operated to set the reception frequency by the reception unit 35, and the frequency is increased by pressing the switch 33a, and the frequency is decreased by pressing the switch 33b. Thus, the frequency control of the receiving unit 35 is enabled. The frequency set by operating the switches 33a and 33b is displayed on the display unit 32 as described above. The frequency thus set is output from the control unit 31 to the receiving unit 35 as channel selection data.

  In the present embodiment, a plurality of reception frequencies can be set. For example, the frequencies of two broadcast stations, a primary station and a secondary station, can be set. The set two frequencies are output from the control unit 31 to the receiving unit 35 with the channel selection data or accompanying it, distinguishing the primary station and the secondary station depending on the priority level.

  For example, the primary station (first broadcasting station) with high priority sets a frequency (for example, 80.0 MHz for commercial broadcasting stations) for receiving the earthquake early warning, and the secondary station (second broadcasting station with low priority). ) Is set to a frequency for receiving an emergency alert broadcast (for example, 83.6 MHz of the Japan Broadcasting Corporation) so that the emergency alert broadcast is received after the emergency earthquake warning is first received, as will be described later. It is possible to set the order of reception.

  If the earthquake early warning that is broadcast by the Japan Broadcasting Corporation is broadcast to all regions or regions in Japan, regardless of the location of the epicenter, the frequency of the earthquake early warning is used. When the frequency of the association's broadcasting station is set, the earthquake does not affect the area or region where the route of the route bus 100 is included, and it is not necessary to take an emergency response when receiving an earthquake early warning However, the receiving device 30 receives the earthquake early warning.

  On the other hand, generally, private broadcasting stations have a limited broadcasting area (for example, Gifu FM Broadcasting (Gifu FM Broadcasting Co., Ltd.)) In such a case, the frequency of a private broadcasting station centering on the area or region where the travel route of the route bus 100 is included is set as the frequency for receiving the earthquake early warning. Thereby, the problem that the receiving device 30 receives an unnecessary earthquake early warning can be solved.

  As for emergency warning broadcasting, the Japan Broadcasting Corporation is designated as a “designated public institution” in the Disaster Countermeasures Basic Act and the Large Scale Earthquake Countermeasures Act. Broadcast an emergency warning broadcast. For this reason, if the private broadcasting station set by the primary station does not broadcast emergency warning broadcasts or if it is not clear whether to broadcast it, the frequency for receiving the earthquake early warning is set as the secondary station in Japan. By setting the frequency to the broadcasting association frequency, the possibility that the receiving device 30 receives the emergency warning broadcast can be increased.

  The switch 33c is a test switch operated to confirm the reception state of the selected frequency. Usually, broadcast reception sound (audio output) that is not output to the built-in speaker 38 unless an emergency earthquake warning or emergency warning broadcast is received. Is output to the built-in speaker 38 by pressing the switch 33c, so that the amplifier 37 can be controlled via the controller 31. When a plurality of reception frequencies are set, by pressing the switch 33c a plurality of times, broadcast reception sounds corresponding to the respective frequencies are output in the set order.

  The switches 33d to 33g are emergency message selection switches that are operated to display a predetermined emergency message (predetermined message) on the liquid crystal display unit 26 of the fare display device 20 described above, and by pressing the switches 33d to 33g. As will be described later, a message output command (identification information of a predetermined message) corresponding to each of the switches 33d to 33g is sent from the control unit 31 to the fare display device 20.

  Note that the name (message name) of the emergency message corresponding to each of the switches 33d to 33g is displayed in advance in each message frame 30b 'of the operation panel 30b provided with the switches 33d to 33g. For example, “when earthquake early warning is announced” is displayed in the message frame 30b ′ of the switch 33d. Similarly, for example, “when tsunami warning is announced (1)” is displayed in the message frame 30b ′ of the switch 33e, and “when tsunami warning is announced (2)” is displayed in the message frame 30b ′ of the switch 33f.

  Accordingly, when the switch 33d is pressed, for example, a catfish logo mark (Earthquake Early Warning User Council established) as shown in FIG. When displaying, it can be made to recognize a crew member. In addition, for example, as a display related to emergency warning broadcasting that conveys a tsunami warning, when the switch 33e is pressed, the pictogram shown in FIG. 9A is displayed on the fare display device 20 in the vehicle, and when the switch 33f is pressed, When the warning information reception message Ed shown in FIG. 10 (B) is displayed on the destination display device 51 outside the vehicle, these associations can be recognized by the crew.

  Further, the switches 33d to 33g enable an emergency message directed to the passenger to be displayed on the fare display device 20 by the operation thereof. Therefore, as will be described later, during the period when the receiving unit 35 is receiving the earthquake early warning or the emergency warning broadcast, or during a predetermined period after the reception, it is possible to input an operation to prevent an erroneous operation (see FIG. 6). "Selection switch input prohibition process" and "selection switch input permission process").

  When a key that matches the keyhole 34a is inserted into the keyhole 34a and unlocked, the setting unit 34 outputs the unlocking information to the control unit 31 to set the reception frequency by the control unit 31 and others. If the key is not inserted into the keyhole 34a or if the key is inserted but not unlocked (in the locked state), the unlocking information is displayed. Lock setting operation without output. This makes it possible to prevent setting changes due to erroneous operations.

  The receiving unit 35 is configured to be able to receive a broadcast wave including audio information of an early earthquake early warning transmitted from the Japan Broadcasting Corporation or a private broadcasting station. In the present embodiment, among radio waves input from an antenna input, radio waves having a reception frequency set in advance within a predetermined frequency band (for example, 76.0 MHz to 90.0 MHz) are received and audio signals (audio signals are so-called). "Audio signal", the same shall apply hereinafter) receiving circuit that can demodulate and output, and a predetermined chime sound that is added to the beginning of the broadcast when the broadcast station broadcasts an earthquake early warning from this audio signal A detectable chime sound detection circuit, and a start signal detection circuit capable of detecting a first type start signal and a second type start signal added to the beginning of the broadcast when the broadcast station broadcasts an emergency warning broadcast from the audio signal; The detection information output circuit outputs detection results output from these two detection circuits to the control unit 31 as detection information.

  The chime sound detection circuit displays a flag indicating that an emergency warning broadcast has been received in the detection information output circuit until a predetermined time such as 30 seconds or 1 minute elapses after the predetermined chime sound is detected. Output continuously. In addition, the start signal detection circuit detects that the emergency warning broadcast is received until the end signal is detected after detecting either the first type start signal or the second type start signal. A flag that can distinguish the two types is output almost continuously to the detection information output circuit.

  Based on the flags input from the chime sound detection circuit and the start signal detection circuit, the detection information output circuit is configured to receive currently received alarm information as an emergency earthquake warning, an emergency warning broadcast (first type), and an emergency warning broadcast (first Detection information that clearly indicates which of the two types is generated and output to the control unit 31. This detection information is always output to the control unit 31 during reception.

  Thus, the detection information output from the detection information output circuit to the control unit 31 is, as will be described later, an emergency information notification program 31a (emergency information notification process) by the control unit 31 that the currently received broadcast is an emergency earthquake. It is used to determine whether it falls under breaking news or emergency warning broadcasting.

  In the present embodiment, the following description will be made only when one of the earthquake early warning and the emergency warning broadcast is received and when the switch 33c (test switch) for checking the reception state is turned on. Thus, ringing instruction information for causing the amplification unit 37 to function is output from the control unit 31 to the amplification unit 37.

  In the present embodiment, the audio signal output from the receiving unit 35 is also output to the outside of the amplifying unit 37 and the receiving device 30 in addition to the control unit 31 (output to the mark * shown in FIG. 1). . The audio signal output to the amplifying unit 37 is for the crew member to listen to, and the audio signal output to the outside of the receiving device 30 is used for voice announcements directed to the passengers and the outside of the vehicle via the amplifying device 70 described later. Is for.

  As described above, the frequency received by the receiving unit 35 is set by the operation of the switches 33a and 33b, and the reception frequency is set by the channel selection data output from the control unit 31. In the present embodiment, since the frequencies of the two broadcast stations of the primary station and the secondary station are set by the operation by the switches 33a and 33b, in the previous example, the frequency based on the channel selection data input from the control unit 31 is the primary. If it is a station, 80.0 MHz is set, and if it is a secondary station, 83.6 MHz is set.

  The amplifying unit 37 is an audio amplifier capable of amplifying the audio signal output from the receiving unit 35 with a predetermined gain and causing the built-in speaker 38 to ring, and functions when the ringing instruction information is input from the control unit 31. As shown in FIG. 3, the broadcast reception sound (audio output) amplified by the amplification unit 37 is output to the outside from the reception device 30 through the speaker hole 30c formed in the casing 30a. Further, a rotatable volume knob 37a is provided in the vicinity of the speaker hole 30c, and the sound volume can be adjusted (gain adjusted) from the outside by this rotating position. As a result, the crew can listen to the broadcast output from the receiving device 30 at a volume that is easy for them to hear.

  The external antenna 39 is an aerial that is configured to be able to capture radio waves of broadcasts and emergency warning broadcasts that include voice information of emergency earthquake warnings transmitted from the Japan Broadcasting Corporation and private broadcast stations. Connected to the input. The external antenna 39 is normally installed outside the route bus 100, but may be installed in the vehicle. Further, depending on the reception frequency of the reception unit 35, the external antenna 39 may be built in the reception device 30 without being provided outside the reception device 30.

[Configuration of Stop Display Control Device 41, Destination Display Device 51, etc.]
Next, the configuration outline of the stop display control device 41, the stop display push button 43, the destination display device 51, the on / off display device 53, the speech synthesizer 60, the amplification device 70, etc. will be briefly described with reference to FIGS. To do.

  As shown in FIGS. 1 and 2, the stop display control device 41 is a control device that performs lighting display control of stop display push buttons 43 provided at a plurality of locations in the route bus 100. As described above, the stop display push button 43 notifies all of the passengers that the route bus 100 is scheduled to stop at the next stop when the button 43b is pressed. The display unit 43a lights up. This lighting control is performed by the stop display control device 41.

  In the present embodiment, for the stop display control device 41 that functions in this way, all the display parts 43a of the plurality of stop display push buttons 43 are further in a predetermined cycle (a cycle in which the passenger can visually recognize the blinking state, for example, It is configured to be able to control blinking so as to blink almost simultaneously at intervals of 0.5 seconds to 1.5 seconds). Further, the fare display device 20 is configured so that the fare display device 20 can output the blinking control information instructing the stop display control device 41 to start such blinking control. Thereby, it becomes possible to blink all the display parts 43a of the plurality of stop display push buttons 43 almost simultaneously by a stop indicator light blinking process described later.

  The destination display device 51 and the on-board display device 53 are, for example, LED display devices configured by arranging multicolor light emitting diodes that can emit light in three colors of red, orange, and green in a matrix, and are input from the outside. It is configured to be able to display characters and figures that can be expressed in dots based on character codes, control codes, and the like. The character code is a concept included in the text data.

  The destination display device 51 is for displaying the destination name of the route bus 100 and the names of main transit stops. The on-and-off display device 53 is displayed when the route bus 100 is stopped at the stop, and indicates that there are passengers who are getting on or off the route bus 100 and pay attention to drivers of surrounding vehicles. It is for encouraging.

  In the present embodiment, the destination display device 51 and the on-boarding display device 53 are provided in front of or behind the route bus 100, or on the side between the boarding port 100a and the boarding port 100b, as described above. Therefore, as will be described later, a plurality of character codes constituting the emergency message are displayed in the fare by the preliminary information output process (FIG. 7; S205) and the alarm information output process (FIG. 7; S305) by the fare display device 20. By outputting the information from the device 20 to the destination display device 51 or the on-board display device 53, the emergency message can be visually recognized to passengers or pedestrians of vehicles traveling or stopping outside the bus 100. can do.

  As described above, the speech synthesizer 60 is installed above the driver's seat 100d and generates a speech signal such as an in-vehicle announcement by synthesized speech and outputs it to the amplifier 70. In addition to the messages stored in advance, For example, a synthesized speech can be generated based on text data (character code) input from the outside, and the synthesized speech signal can be output to the outside.

  In this embodiment, it is connected to the amplifying device 70 and configured to be able to output a sound announcement to the in-vehicle speaker 71 and the out-of-vehicle speaker 73. For this reason, by outputting a plurality of character codes constituting the emergency message from the fare display device 20 to the speech synthesizer 60 by voice output control processing (FIG. 7; S209, S309) by the fare display device 20 described later, In cooperation with the amplification device 70 and the like described below, the emergency message can be notified to an occupant or a pedestrian of the vehicle traveling or stopped outside the route bus 100 in an audible manner.

  As described above, the amplifying device 70 is an audio amplifier that can amplify an audio signal input from a microphone such as the driver's seat 100d with a predetermined gain and cause the in-vehicle speaker 71 and the out-of-vehicle speaker 73 to ring, and is omitted from the driver's seat 100d. The output destination can be switched to the in-vehicle speaker 71 or the out-of-vehicle speaker 73 by the changeover switch, and the output destination can be switched to the out-of-vehicle speaker 73 by a switching control command output from the fare display device 20.

  In the present embodiment, the changeover switch of the driver's seat 100d selects the in-vehicle speaker 71 as the normal output destination (the default setting is the in-vehicle speaker 71), and therefore, a switching control command for switching the output destination to the outside speaker 73. Is not input from the fare display device 20, the in-vehicle speaker 71 is automatically selected and the sound is output only to the inside of the route bus 100.

  In the present embodiment, since the audio signal output from the receiving unit 35 is also output to the amplifying device 70, the received sound or the audio announcement by the broadcast received by the receiving device 30 is also input to the amplifying device 70 as an audio signal. (Input from * mark shown in FIG. 1). Thereby, the reception sound and the voice announcement output from the receiving device 30 can be output from the in-vehicle speaker 71 and the out-of-vehicle speaker 73 by the switching control command output from the fare display device 20.

  Here, the fare display program 23b, the emergency information reading program 23c, the emergency information output program 23d, the screen display control program 23e, the voice output control program 23f, and the receiving device 30 stored in the system memory 23 of the fare display device 20 are stored. An outline of functions of software such as the emergency information notification program 31a stored in FIG.

  The fare display program 23b generates a list of fare displays, which is a basic function of the fare display device 20, based on the operation information data 24a and the fare information data 24b stored in the data memory 24, and then displays the liquid crystal display via the GPU 25. Image data that can be displayed on the unit 26 is output to the GPU 25. Further, as described with reference to FIG. 4, in addition to such a list of fare displays, content data 24 c (contents Ca to Cf) read from the data memory 24 are also displayed on the liquid crystal display unit 26 via the GPU 25. Displayable image data is output to the GPU 25. In addition, this fare display program 23b is automatically started, for example, at the time of the operation route selection operation of the route bus 100, separately from the emergency information reading program 23c and the like.

  The emergency information reading program 23c reads the emergency information data 24d stored in the data memory 24 from the data memory 24. The message output command sent from the control unit 31 to the fare display device 20 by the emergency information notification program 31a described later. Therefore, it is activated and executed by the MPU 21.

  The emergency information output program 23d is also executed by the MPU 21, and the emergency information data 24d read from the emergency information reading program 23c is transferred to the liquid crystal display unit 26, the destination display device 51, the on-boarding display device 53, and the amplification device 70. Output data suitable for the output device at the output destination.

  The screen display control program 23e is also executed by the MPU 21, and among the output data (emergency message) generated by the emergency information output program 23d, the liquid crystal display unit 26, the destination display device 51, the on-board display device 53, etc. What is output to the display device is output to the GPU 25 so that the image data can be controlled via the GPU 25, or is output to the destination display device 51 and the on-board display device 53.

  The voice output control program 23f is also executed by the MPU 21, and among the output data (emergency message) generated by the emergency information output program 23d, an in-vehicle speaker 71 and an out-of-vehicle speaker are connected via the voice synthesizer 60 and the amplifier 70. What is output to the audio equipment 73 or the like is output to the speech synthesizer 60 or the like, and the switching control of the amplifier 70 is performed.

  The emergency information notification program 31a performs an emergency information notification process by being executed by the control unit 31 of the receiving device 30, and realizes an emergency information notification function by the system 10. This program is activated when the receiving device 30 is powered on.

  By configuring the system 10 including the fare display device 20 and the receiving device 30 as described above, the system 10 can perform each control process as shown in FIGS. A voice announcement of the emergency message is displayed, and the emergency message is displayed on the liquid crystal display unit 26 as shown in FIGS.

  6 is a flowchart showing a flow of emergency information notification processing by the fare display device 20, and FIG. 7 is an emergency earthquake warning processing (FIG. 7 (A)) and emergency warning broadcast processing (FIG. 7 (B)). Each of the flowcharts showing the flow is shown. 8 is an explanatory diagram showing an example of display by the liquid crystal display unit 26, FIG. 9 is an explanatory diagram showing an example of display by the liquid crystal display unit 26, and FIG. 10 is an explanatory diagram showing an example of display by the destination display device 51. , Respectively.

  When the power of the receiving device 30 is turned on, the emergency information notification program 31a is started by the control unit 31 and the emergency information notification process is started. In the present embodiment, when the power of the receiving device 30 is turned on, the fare display device 20 is already activated and is in a standby state waiting for a command sent from the receiving device 30 to be described. Assumed.

  As shown in FIG. 6, first, a predetermined initialization process is performed in step S100. In this initialization process, for example, a counter for each timer described later is reset and a predetermined flag is cleared. In the present embodiment, the channel selection data output from the control unit 31 to the reception unit 35 is set to a primary station having a high priority (for example, a private broadcasting station) and output to the reception unit 35, and then the reception unit Wait until a predetermined time required for 35 reception frequencies to stabilize.

  In the next step S101, a selection switch input prohibition process is performed. That is, even if ON information of any switch is input from the operation unit 33 by the operation of the switches 33d to 33g, the input is prohibited or invalidated. Specifically, when receiving an input from the operation unit 33 and reading the input port corresponding to each of the switches 33d to 33g, masking is performed by setting a mask bit or the like, or information on the corresponding input port is logically processed. For example, signal control is performed by hardware so that the data cannot be read by a gate circuit or the like.

  As a result, after this process, the operation input of the switches 33d to 33g is ignored until the selection switch input permission process is performed. Therefore, even if the switch 33d or the like is accidentally pressed, the switches 33d to 33g are handled. The message output command is not sent to the fare display device 20, and an erroneous operation can be prevented.

  In the subsequent step S103, it is determined whether or not an emergency earthquake warning has been received. In this process, based on the detection information output from the receiving unit 35, it is determined whether or not the receiving unit 35 is currently receiving the earthquake early warning. If it is determined that the earthquake early warning is received (S103; Yes), the process proceeds to the selection switch input permission processing in step S105, and if it is determined that the emergency earthquake early warning is not received (S103; No). ) Step S103 is performed again, and step S103 is repeated until an emergency earthquake warning is received by the primary station (private broadcasting station in this embodiment).

  In the next step S105, a selection switch input permission process is performed. That is, the on information of the switches 33d to 33g disabled by step S101 is validated. Accordingly, when the on information is input from the operation unit 33 by the operation of the switches 33d to 33g, information processing based on the information is performed. In step S105, the timer counter reset in step S100 is started. This counter is used to determine whether or not the time since the start of receiving the earthquake early warning has exceeded a predetermined time.

  In the subsequent step S106, an audio output control process is performed. This process is performed in order to output the audio signal output from the receiving unit 35 that is currently receiving the earthquake early warning to the amplifying unit 37 and the amplifying device 70. Information is output from the control unit 31 to the amplification unit 37. In addition, the audio signal output from the receiving unit 35 is directly input to the amplifying apparatus 70.

  As a result, the amplifying unit 37 and the amplifying device 70 to which the audio signal is input from the receiving unit 35 amplify the audio signal with a predetermined gain and output the broadcast reception sound based on the emergency earthquake warning from the built-in speaker 38 or the in-vehicle speaker 71. For this reason, the crew member of the driver's seat 100d hears the announcement of the earthquake early warning and its contents as information from the ear by the broadcast reception sound output from the built-in speaker 38 and the passenger of the passenger seat 100c from the in-vehicle speaker 71, respectively. Can be recognized.

  In step S107, selection switch input detection processing is performed. With the voice output control process in step S106, the crew is in a situation where the contents of the emergency earthquake warning can be confirmed. For this reason, since there is a possibility that the selection switch is operated by the crew member, it is determined whether or not the selection switch is pressed and turned on, and if it is turned on, which selection switch is turned on. To detect.

  Specifically, based on input information input from the operation unit 33, it is detected which of the switches 33d to 33g has been operated. For example, when the switch 33d is pressed, input information of the switch 33d is detected. In this case, the crew member selects the catfish logo or the like as described above on the liquid crystal display unit 26 in response to the receipt of the earthquake early warning, and intends to inform the passenger of that fact. It can be seen that the switch was operated.

  In the subsequent step S108, based on the detection result in step S107, a determination process is performed as to whether or not there is a selection switch input. When it is determined that there is an input from the selection switch (S108; Yes), a message output command is sent to the fare display device 20, and the process proceeds to step S200, and it is determined that there is no input from the selection switch. (S108; No), the process proceeds to step S109.

  In step S109, a determination process is performed as to whether or not a predetermined time has elapsed since the start of receiving the earthquake early warning. That is, normally, the emergency earthquake bulletin is not added with an end signal like the emergency warning broadcast, so when a certain time or more has passed since the reception of the emergency earthquake bulletin in step S103, the emergency earthquake bulletin broadcast is performed. It may have been terminated. Therefore, as described above, based on the value of the counter that started counting in step S105, it is determined whether or not the time from the start of receiving the emergency alert broadcast exceeds a predetermined time, and the predetermined time has passed. If yes (S109; Yes), even if the selection switch has not yet been input, the process proceeds to step S111 to prepare for the next expected emergency alert broadcast. Note that the “predetermined time” here is set to, for example, 30 seconds to 1 minute because it is assumed that the main motion due to the S wave can be reached after receiving the earthquake early warning from several seconds to several tens of seconds. The

  On the other hand, if it is determined in step S109 that the predetermined time has not yet elapsed (S109; No), there is a high possibility that the earthquake early warning has been received. The selection switch input detection process is performed. That is, as long as the earthquake early warning broadcast is continuously received, steps S107, S108, and S109 are repeated to wait for the input of the selection switch.

  For emergency earthquake warnings, if a chime sound or an end signal indicating the end of the broadcast is added to the broadcast, reception of the earthquake early warning is terminated, as in the case of an emergency warning broadcast described later. Whether or not a predetermined time has elapsed since the start of receiving the earthquake early warning may be determined (S119).

  In step S200, emergency earthquake warning processing is performed. This process is performed in the fare display device 20 that has received the message output command sent from the receiving device 30 when the receiving device 30 receives the earthquake early warning. For this reason, details of each process performed by the MPU 21 of the fare display device 20 are shown in FIG. 7A, and an explanatory diagram of a display example by the liquid crystal display unit 26 is shown in FIG. This will be described with reference to FIGS.

  As shown in FIG. 7 (A), in the earthquake early warning process, first, a stop indicator lamp blinking process is performed in step S201. In this process, blinking control information is output from the fare display device 20 to the stop display control device 41, whereby the blinking control by the stop display control device 41 is started, and a plurality of provided in the vicinity of the passenger seat. All the display portions 43a of the stop display push button 43 of the vehicle blink at a cycle that can be visually recognized by the passenger.

  Then, since many passengers who have witnessed such blinking of the display unit 43a notice the abnormality of the stop display push button 43 that does not normally blink, the direction of the driver seat 100d, That is, attention is paid to the front of the route bus 100. As a result, the line of sight of the passenger is also directed toward the liquid crystal display unit 26 of the fare display device 20, so that it is possible to make a kick that attracts attention to both screens 26 a and 26 b of the liquid crystal display unit 26. .

  In the next step S203, a preliminary information reading process is performed. In this process, an emergency message corresponding to the selection switch operated by the crew member is selected and read from the emergency information data 24d of the data memory 24, and the emergency information data 24d is based on the input information detected in step S107 described above. And the data of the emergency message associated with the input information is read out. The selection switch of the switches 33d to 33g and the emergency message are associated with each other by the message output command (identification information of the predetermined message) corresponding to the switches 33d to 33g, and the emergency message is searched based on this. Read out.

  In addition to text data in general file format, various data such as image data (jpg, avi, mpg, swf, etc.) and audio data (mp3, wav, wma, etc.) Includes data formats. In addition, output destination information for specifying an output destination of the emergency message is added to the emergency message. This process is performed by executing the emergency information reading program 23c.

  In the previous example, the emergency information data 24d associated with the switch 33d is retrieved from the input information and a predetermined emergency message is read from the data memory 24, so that an emergency earthquake bulletin is received as shown in FIG. Image data that can display the catfish logo Ea that makes it appear that the image has been received, image data that can display the pictogram Eb that makes the image of stopping the bus and the characters that stop the route bus 100 because of receiving the earthquake early warning The image data of the two-screen specification is acquired. Further, output image information for designating the liquid crystal display unit 26 having a two-screen configuration is added to the image data of the two-screen specification as an output device.

  In the subsequent step S205, a breaking information output process is performed. This process outputs the urgent message read out in step S203 to the liquid crystal display unit 26, the destination display device 51, the on-board display device 53, the amplification device 70, and the like, so that the output data suitable for the output device at the output destination Is generated. In the previous example, output destination information for designating the liquid crystal display unit 26 as an output device is added as an emergency message. Therefore, control information for the GPU 25 can be output to the liquid crystal display unit 26 having a two-screen configuration. Output data to which etc. are added is generated. This process is performed by executing the emergency information output program 23d.

  When the emergency message read from the data memory 24 is text data, any one, two, or all of the destination display device 51, the on / off display device 53, and the speech synthesizer 60 are output destinations. In the case of audio data, the amplifying apparatus 70 that designates one or both of the in-vehicle speaker 71 and the out-of-vehicle speaker 73 is the output destination. As described above, when there are a plurality of output destination output devices in the system configuration, which one of the plurality of output devices is to be output to all output devices or the like is indicated in the emergency message. It is determined based on the added output destination information.

  In the subsequent step S207, a screen display control process is performed. In this process, among the output data (emergency message) generated in step S205, the data output to the display device such as the liquid crystal display unit 26, the destination display device 51 or the on-board display device 53, and the image data to the GPU 25. And output to the GPU 25 in a controllable manner, or to the destination display device 51 and the on-boarding display device 53. If the output destination according to the output destination information is not a display device such as the liquid crystal display unit 26, the destination display device 51, or the on-board display device 53, the processing at step S207 is skipped and the processing proceeds to the subsequent step S209. This process is performed by executing the screen display control program 23e.

  In the above example, image data (image data of two screen specifications) that can display the logo mark Ea and the pictogram Eb is output to the GPU 25 as output data, and as shown in FIG. On both screens 26a and 26b of the liquid crystal display unit 26 that displayed the fare table Da and Db, an emergency message composed of a logo mark Ea and a pictogram Eb as shown in FIG. Screens 26a and 26b are displayed. As a result, the passenger who has turned his / her line of sight to the liquid crystal display unit 26 of the fare display device 20 by the stop indicator blinking process of step S201 stops the announcement of the earthquake early warning and the route bus 100 by the emergency message by the liquid crystal display unit 26. It can be recognized as visual information from the eyes.

  In the next step S209, an audio output control process is performed. In this process, the output data (emergency message) generated in step S205 is output to the audio equipment such as the in-vehicle speaker 71 and the out-of-vehicle speaker 73 via the voice synthesizer 60 and the amplifier 70. The signal is output to the device 60 and the like, and the switching control of the amplifying device 70 is performed. When the output destination according to the output destination information is not an acoustic device such as the in-vehicle speaker 71 or the out-of-vehicle speaker 73, the process in step S209 is skipped. This process is performed by executing the audio output control program 23f.

  If the emergency information data 24d read from the data memory 24 is text data and the output destination information specifies the output destination to the outside speaker 73 as an emergency message, the text data is output to the speech synthesizer 60. At the same time, a switching control command for switching the output destination to the outside speaker 73 is output to the amplifying apparatus 70. As a result, since the voice signal of the emergency message generated based on the text data is output from the voice synthesizer 60, the amplifier 70 to which the voice signal is input is amplified by a predetermined gain and causes the speaker 73 outside the vehicle to ring. An emergency message is announced with a sound (synthetic sound) of a corresponding volume.

  On the other hand, when the output destination information specifies the output destination to the in-vehicle speaker 71, the text data is output to the speech synthesizer 60, while the switching control command is not output to the amplifier 70. This is because, as described above, the output destination of the amplification device 70 is set to the in-vehicle speaker 71 by default. Thus, the synthesized voice of the generated emergency message is output from the in-vehicle speaker 71 and announced.

  If the emergency information data 24d read from the data memory 24 is audio data and the output destination information specifies the output destination to the outside speaker 73 as an emergency message, the audio data is sent to the amplifying device 70. At the same time, a switching control command for switching the output destination to the outside speaker 73 is output to the amplifying apparatus 70. As a result, the amplifying apparatus 70 to which the voice signal of the emergency message based on the voice data is input is amplified with a predetermined gain to cause the vehicle speaker 73 to ring, and the emergency message is announced with a voice (synthesized voice) of a corresponding volume.

  On the other hand, when the output destination information designates the output destination as the in-vehicle speaker 71, the switching control command is not output only by outputting the audio data to the amplifying apparatus 70 because of the default setting described above. Thereby, the emergency message by the said audio | speech data is output from the speaker 71 in a vehicle, and is announced.

  When the voice output control process in step S209 is completed, the information processing by the emergency earthquake warning process in step S200 is completed. Thereby, the information processing by the MPU 21 of the fare display device 20 is temporarily ended, and the processing returns to the information processing by the control unit 31 of the receiving device 30. Accordingly, the process proceeds to step S111 shown in FIG. 6 and will be described with reference to FIG. 6 again.

  As shown in FIG. 6, in step S111, selection switch input prohibition processing is performed. That is, as in the above-described step S101, the operation of the switches 33d to 33g invalidates the input even if any switch ON information is input from the operation unit 33. Until the permission process is performed, the operation input of the switches 33d to 33g is ignored to prevent an erroneous operation.

  In the next step S112, reception preparation processing is performed. This process is accompanied by changing the reception frequency of the reception unit 35 from the previous primary station to that of the secondary station. In this process, when the frequency of the secondary station (Japan Broadcasting Corporation) is set in addition to the primary station as the reception frequency of the receiving unit 35 as in the present embodiment, the frequency of the secondary station is set in the channel selection data. To do.

  Then, after waiting for a predetermined time required for the reception frequency of the receiving unit 35 to stabilize, the timer counter reset in step S100 is started. This counter is used to determine whether or not the time during which an emergency alert broadcast cannot be received exceeds a predetermined time. If there is no need to change the reception frequency from the primary station, only the process of starting the timer counter is performed.

  In the subsequent step S113, a determination process is performed as to whether or not an emergency warning broadcast has been received. In this process, based on the detection information output from the receiving unit 35, it is determined whether the receiving unit 35 is currently receiving an emergency alert broadcast. If it is determined that the emergency alert broadcast is received (S113; Yes), the process proceeds to the selection switch input permission process in step S115, and if it is determined that the emergency alert broadcast is not received (S113; No). ), The process proceeds to step S114.

  In step S114, based on the value of the counter that started counting in step S111, it is determined whether or not the time during which the emergency alert broadcast cannot be received exceeds a predetermined time. If the predetermined time has not elapsed (S114; No), the process proceeds to step S113, and it is determined again whether or not an emergency warning broadcast is received. On the other hand, when the predetermined time has passed (S114; Yes), the process proceeds to the initialization process of step S100, and preparations for receiving the earthquake early warning are prepared again. Thus, steps S113 and S114 are repeated until an emergency warning broadcast is received within a predetermined time by the secondary station (Japan Broadcasting Corporation in this embodiment).

  Note that the “predetermined time” here means that it is assumed that the main motion due to S waves can reach from several seconds to several tens of seconds from the reception of the earthquake early warning, and that the tsunami warning is issued from the occurrence of the earthquake. Since the time from the announcement to the broadcast of the emergency alert broadcast is within about 5 minutes, it is set to about 1 to 5 minutes or 10 minutes, for example.

  In the next step S115, selection switch input permission processing is performed. That is, the on information of the switches 33d to 33g disabled by step S111 is validated. Accordingly, when the on information is input from the operation unit 33 by the operation of the switches 33d to 33g, information processing based on the information is performed. In step S115, the timer counter reset in step S100 is started. This counter is used to determine whether or not the time from the start of receiving the emergency alert broadcast exceeds a predetermined time.

  In a succeeding step S116, an audio output control process is performed. This process is performed in order to output the audio signal output from the receiving unit 35 currently receiving the emergency alert broadcast to the amplifying unit 37, and the ringing instruction information for causing the amplifying unit 37 to function is transmitted from the control unit 31. Output to the amplifying unit 37. As a result, the audio signal output from the receiving unit 35 is amplified by the amplifying unit 37 and output from the built-in speaker 38. Therefore, the crew member of the driver's seat 100d can generate an emergency warning by the broadcast reception sound output from the built-in speaker 38. It is possible to recognize the announcement and its contents as auditory information from the ear.

  In step S117, selection switch input detection processing is performed. By the audio output control process in step S116, the crew is in a situation where the contents of the emergency warning broadcast can be confirmed. For this reason, since there is a possibility that the selection switch is operated by the crew member, it is determined whether or not the selection switch is pressed and turned on, and if it is turned on, which selection switch is turned on. To detect.

  Specifically, based on input information input from the operation unit 33, it is detected which of the switches 33d to 33g has been operated. For example, when the tsunami warning is announced and the switch 33e is pressed from the contents of the emergency warning broadcast, the input information of the switch 33e is detected. In this case, the crew member displays the tsunami warning pictogram as shown in FIG. 9 (A) on the fare display device 20 in the vehicle due to the reception of the emergency warning broadcast, and informs the passengers of the fact. It can be seen that the selection switch was operated with the intention of communicating.

  In the subsequent step S118, based on the detection result in step S117, a process for determining whether or not there is an input of the selection switch is performed. If it is determined that there is an input from the selection switch (S118; Yes), a message output command is sent to the fare display device 20 and the process proceeds to step S300, and it is determined that there is no input from the selection switch. (S118; No), the process proceeds to step S119.

  In step S119, a determination process is performed to determine whether or not the reception of the emergency warning broadcast has ended, or whether or not a predetermined time has elapsed since the start of receiving the earthquake early warning. When a certain period of time has elapsed since the reception of the emergency warning broadcast in step S113, there is a possibility that the emergency warning broadcast has ended. Therefore, based on the detection information output from the receiving unit 35 that has received the end signal, it is determined whether or not the emergency warning broadcast has ended. If the broadcast has already ended (S119; Yes). Even if the selection switch has not yet been input, the process proceeds to step S100 to prepare for receiving the earthquake early warning again.

  Even when the receiving unit 35 has not received the end signal, the emergency warning broadcast may have ended when a certain time or more has elapsed since the reception of the emergency warning broadcast in step S113. For this reason, as described above, based on the value of the counter that started counting in step S115, it is determined whether or not the time from the start of receiving the emergency alert broadcast exceeds a predetermined time, and the predetermined time has passed. If YES in step S119, the process returns to step S100. Since the “predetermined time” here depends on the broadcast time of the emergency alert broadcast, for example, based on statistical data on the broadcast time of the emergency alert broadcast that has been broadcast so far, Maximum time etc. are set.

  On the other hand, when it is determined in step S119 that the emergency alert broadcast is still received from the detection information output from the receiving unit 35, or when it is determined that the predetermined time has not elapsed ( S119; No), returning to step S117, the selection switch input detection process is performed again. That is, as long as the emergency warning broadcast is continuously received, steps S117, S118, and S119 are repeated to wait for the input of the selection switch.

  In step S300, emergency alert broadcast processing is performed. This process is performed in the fare display device 20 that has received the message output command sent from the receiving device 30 when the receiving device 30 receives the emergency alert broadcast. Therefore, details of each process performed by the MPU 21 of the fare display device 20 are shown in FIG. 7B, and an explanatory diagram of a display example by the liquid crystal display unit 26 is shown in FIG. This will be described with reference to FIG. 7B and FIG.

  As shown in FIG. 7 (B), in emergency alert broadcasting, first, a stop indicator lamp blinking process is performed in step S301. This process is the same as step S201 already described with reference to FIG.

  In the next step S303, an alarm information reading process is performed. In this process, the emergency message corresponding to the selection switch operated by the crew is selected and read from the emergency information data 24d of the data memory 24, and the emergency information data 24d is based on the input information detected in step S117 described above. And the data of the emergency message associated with the input information is read out. It should be noted that the data read out here includes the same data format as in step S203 already described with reference to FIG. 7A, and output destination information is also added to the emergency message. This process is performed by executing the emergency information reading program 23c.

  In the previous example, the emergency information data 24d associated with the switch 33e is searched from the input information, and a predetermined emergency message is read from the data memory 24, so that a tsunami warning is received as shown in FIG. Image data having two screen specifications, that is, image data that can display a pictogram Fa that makes it appear and image data that can display an emergency response manual Fb that explains an action instruction to a passenger are acquired. Further, output image information for designating the liquid crystal display unit 26 having a two-screen configuration is added to the image data of the two-screen specification as an output device.

  Further, when the emergency information data 24d includes image data or the like for guiding the emergency evacuation site to the passengers with the input information of the switch 33e, for example, the emergency evacuation site as shown in FIG. The image data capable of displaying the emergency evacuation site guidance Fc for prompting evacuation and the image data capable of displaying the map Fd indicating the location information of the evacuation site are read from the data memory 24 and acquired.

  Furthermore, as another example, when the crew member has pushed the switch 33g in order to inform the passengers and pedestrians of the vehicle traveling or stopping outside the bus 100 that the tsunami warning has been announced, As emergency information data 24d associated with the switch 33g from the input information, for example, a warning information reception message Ed of “receiving tsunami warning” as shown in FIG. The character code (text data) that can be displayed on is read out from the data memory 24 and acquired.

  In subsequent step S305, an alarm information output process is performed. This process is also the same as step S205 already described with reference to FIG. In the above example, output destination information for designating the liquid crystal display unit 26 as an output device is added as an urgent message, so that this image data can be output to the two-screen liquid crystal display unit 26 to the GPU 25. Output data to which control information or the like is added is generated. This process is performed by executing the emergency information output program 23d.

  In the subsequent step S307, a screen display control process is performed. This process is also the same as step S207 already described with reference to FIG. If the output destination based on the output destination information is not a display device such as the liquid crystal display unit 26, the destination display device 51, or the on-board display device 53, the processing at Step S307 is skipped and the processing proceeds to Step S309. To do. This process is performed by executing the screen display control program 23e.

  In the previous example, image data that can display the pictogram Fa and the emergency response manual Fb (image data of the two-screen specification) is output to the GPU 25 as output data, and as shown in FIG. The two screens 26a and 26b of the liquid crystal display unit 26 displaying the emergency message including the logo mark Ea and the pictogram Eb are displayed on the pictogram Fa and the emergency response manual Fb as shown in FIG. 9A. Is displayed. As a result, the passenger who has turned his / her line of sight to the liquid crystal display unit 26 of the fare display device 20 by the blinking process of the stop indicator lamp in step S301 is notified of the emergency warning and the action by the emergency response manual Fb by the emergency message by the liquid crystal display unit 26. The contents of the instruction can be visually recognized as information from the eyes.

  Further, the emergency evacuation site guidance Fc and the map Fd displayable image data (two-screen image data) are output to the GPU 25 as output data, so that the emergency evacuation site guidance as shown in FIG. Fc and map Fd are displayed. It becomes possible to visually recognize information about emergency evacuation sites.

  For image data related to a place (position) such as an emergency evacuation place, the location information of the place or tag information that replaces it is added, so that the nearest stop (the nearest stop) to the current location of the route bus 100 is added. Based on the name or number, the image data of the location geographically or temporally closest to the current position of the route bus 100 may be selected from the emergency information data 24d of the data memory 24. The position information of the route bus 100 may be latitude / longitude coordinate information obtained from a GPS receiver mounted on the route bus 100. Thereby, since accurate evacuation information according to the current position of the route bus 100 can be provided to the passenger, it is possible to quickly move to an evacuation place or the like.

  Furthermore, as mentioned as another example, the output destination information for designating the output destination to the destination display device 51 or the on-board display device 53 in the character code (text data) of the emergency information data 24d acquired from the data memory 24. Is added to the GPU 25 as output data, so that the destination display Dd as shown in FIG. On the destination display device 51 in which a specific destination name is displayed in “□”, an alarm information reception message Ed of “Receiving Tsunami Warning” as shown in FIG. 10B is displayed. The Thereby, the emergency message by an emergency warning can be visually conveyed also to the passenger | crew and pedestrian of the vehicle which drive | work or stop the route bus 100 periphery. In the example shown in FIG. 10B, an emergency message using characters is displayed, but an emergency message using a graphic that can be expressed in dots can also be displayed (the same applies to the on-boarding display device 53).

  In the next step S309, an audio output control process is performed. This process is also the same as step S207 already described with reference to FIG. If the output destination based on the output destination information is not an audio device such as the in-vehicle speaker 71 or the out-of-vehicle speaker 73, the process in step S309 is skipped. This process is performed by executing the audio output control program 23f.

  For example, when output destination information for designating the speaker 73 outside the vehicle is also added to the character code (text data) displayed by the destination display device 51 as shown in FIG. If the emergency information data 24d read from the data memory 24 is text data and the output destination information specifies the output destination to the outside speaker 73 as an emergency message, the text data is output to the speech synthesizer 60. At the same time, a switching control command for switching the output destination to the outside speaker 73 is output to the amplifying apparatus 70.

  In this example, since the voice signal of the emergency message generated based on the character code is output from the voice synthesizer 60 to the speaker 73 outside the vehicle via the amplifier 70, the synthesized voice having a corresponding volume is output from the speaker 73 outside the vehicle. An urgent message stating “Receiving tsunami warning” is announced. Therefore, it is possible to audibly transmit an emergency message by an emergency warning to a passenger or a pedestrian of a vehicle traveling or stopping around the route bus 100.

  When the audio output control process in step S309 is completed, the information processing by the emergency warning broadcast process in step S300 is completed. Thereby, the information processing by the MPU 21 of the fare display device 20 is completed, and the processing returns to the information processing by the control unit 31 of the receiving device 30. Thereby, as shown in FIG. 6, in order to return to step S100 again, in the receiving apparatus 30, the information processing by each step demonstrated so far is performed again.

  Note that the emergency message (FIG. 8B, FIG. 9, FIG. 10B) displayed on the display device such as the liquid crystal display unit 26 or the destination display device 51 is displayed so as to blink (repetitive blinking display). You may do it. Thereby, a passenger's attention can be urged more effectively.

  In the emergency information notification process (FIG. 6) described above, the “selection switch input permission process” (S105, S115) that permits the input of the switches 33d to 33g is performed immediately after confirmation of the reception of the earthquake early warning (Yes in S103) or emergency warning broadcast Immediately after the end of reception of the earthquake early warning, the “selection switch input prohibition process” (S101, S111) which is positioned immediately after confirmation of reception (Yes in S113) and which electrically prohibits or disables the input of the switches 33d to 33g. (Yes in S109) or after the end of reception of the emergency warning broadcast (Yes in S119), the switch 33d ~ is limited to during the reception of the emergency earthquake bulletin or the emergency warning broadcast by being positioned immediately after the initialization process (S101). 33g input is possible. As a result, when neither the earthquake early warning nor the emergency warning broadcast is received, even if the switches 33d to 33g are accidentally pressed, the fare display device 20 does not display an emergency message or make an audio announcement. This makes it possible to prevent false alarms due to incorrect operation.

  In such a configuration, when there is a possibility that the crew member misses the timing of pressing the switches 33d to 33g, for example, after the end of receiving the earthquake early warning (Yes in S109) or after the end of receiving the emergency alert broadcast (S119) Yes), a “pause process of waiting for about 30 seconds to 3 minutes as a predetermined time after each reception is performed so that“ selection switch input prohibition processing ”(S101, S111) is executed after a predetermined time has elapsed. You may take the structure to make. Thereby, a time margin can be given to operation of switch 33d-33g by a crew member.

  Further, even when the “selection switch input prohibition process” of such switches 33d to 33g is being performed, the fare display device 20 may be provided with a function for forcibly releasing it. For example, when the receiving device 30 is provided with a push button switch with an erroneous operation prevention cover and is turned on, hardware masking or hardware in which signal control is disabled by the control unit 31 described above or The software configuration is added to the control unit 31. Thereby, even if the emergency earthquake bulletin or the emergency warning broadcast is not received, the switch 33d to 33g can be operated by selecting the push button switch with the erroneous operation prevention cover. Therefore, it is possible to cause the fare display device 20 to execute the emergency earthquake warning processing (FIG. 7A) and the emergency warning broadcast processing (FIG. 7B) at an arbitrary timing.

  In the emergency information notification process (FIG. 6) described above, the emergency earthquake warning process (FIG. 7A) is located in step S200, and the emergency alert broadcast process (FIG. 7B) is located in step S300. However, if there is no difference in processing contents between the two in terms of software and processing can be performed in the same manner, a single emergency information broadcasting process may be used. In this case, for example, as shown in FIG. 11, the flow of information processing can be simplified by adopting a configuration capable of receiving both the emergency earthquake bulletin and the emergency warning broadcast. In FIG. 11, steps that perform information processing similar to the steps shown in FIG.

  That is, as shown in FIG. 11, it is determined in step S103 'whether or not either an earthquake early warning or an emergency warning broadcast has been received. This determination process can be understood as a combination of step S103 shown in FIG. 6 and step S113 shown in FIG. 6, and the determination of whether or not an emergency earthquake warning or emergency warning broadcast has been received is received by the receiving unit. This is performed based on the detection information output from 35.

  If any one of them has been received (S103 ′; Yes), after each process in steps S105, S106, and S107, the selection switch is selected in step S108 based on input information input from the operation unit 33. A process for determining whether or not there is an input from (switches 33d to 33g) is performed. If there is a switch input (S108; Yes), the process proceeds to the emergency information broadcast process (S200 ′) described above.

  In step S200 ', processing similar to the emergency earthquake warning processing (S200; FIG. 7 (A)) and emergency warning broadcast processing (S300; FIG. 7 (B)) described with reference to FIG. 7 is performed. That is, each information processing is performed in the same manner as each step described with reference to FIGS. 7A and 7B, and an emergency message as shown in FIGS. It is displayed on the destination display device 51 and the on-board display device 53, and an emergency message is announced from the in-vehicle speaker 71 and the out-of-vehicle speaker 73.

  As described above, according to the present system 10, a plurality of numbers of numbered tickets issued from the numbered ticket issuing machine 103 configured to display character information and graphic information and installed in the route bus 100 and these numbers are displayed.

A display information control device for controlling the in-vehicle information display device to display in a free display area, or (3) to display at a time different from the list display time of the fare display,
An emergency information notification system characterized by comprising: "

  In the embodiment described above, the receiving unit 35 has been described on the assumption that it receives a broadcast wave transmitted from the Japan Broadcasting Corporation or a private broadcasting station. However, for example, a nationwide instantaneous warning system (J-ALERT Business radio transmitted from a route bus operator may be received by the receiving device 30 based on information directly obtained from J Alert. In this case, a configuration is adopted in which the predetermined chime sound, the first type start signal, the second type start signal, and the end signal are added to the beginning of the radio wave by the business radio.

  Further, in the embodiment described above, the receiving device 30 is configured to be able to receive radio waves broadcast from two broadcast stations, a primary station and a secondary station, and receive frequencies corresponding to the primary station and the secondary station (hereinafter, “ "Corresponding frequency") is fixed to one each. For example, it is configured so that a plurality of corresponding frequencies can be set, and the current position of the traveling route bus 100 and the receiving device 30 receive it. The optimum frequency may be selected from a plurality of corresponding frequencies based on the state of the radio wave (the strength of the electric field strength) to be performed. Thus, for example, when the travel route includes a flat or mountainous area, when traveling on a plain where radio waves can easily enter, station A is selected as the primary station, and radio waves from station A are difficult to enter in the mountains. When traveling in a mountainous area, it is possible to select station B, which is more likely to receive radio waves than station A, as a primary station. However, the present system 10 can be applied.

  The current location of the route bus 100 is determined based on the route of the route bus 100 and the map information (map data stored in the data memory 24) based on the name or number of the stop nearest to the current location of the route bus 100 (nearest stop). In order to improve the accuracy of the position information, latitude / longitude coordinate information obtained from a GPS receiver mounted on the route bus 100 can be used. In addition, the state of the radio wave being received is configured to select the strongest signal by comparing the signal strength for each of a plurality of frequencies based on the signal strength information obtained from the signal strength output provided in the receiving unit 35. When giving priority to receivable broadcasting stations, compare the signal strength including the weighting information, and if there are multiple broadcasting stations with almost the same radio field strength, select the broadcasting station with the highest priority. You can choose.

  In addition, if the contents of the earthquake early warning by the emergency earthquake early warning or the emergency warning by the emergency warning broadcast are superimposed on the broadcast wave as digital information, the contents of the earthquake early warning or emergency warning obtained by decoding them are included. Based on this, the emergency information data 24d (collection of emergency messages) stored in the data memory 24 of the fare display device 20 is searched, processed and edited, and displayed on the liquid crystal display unit 26 or the like, or the speech synthesizer 60. The in-vehicle speaker 71 or the like may be sounded via the. Further, the contents of the earthquake early warning and emergency warning obtained by decoding may be directly displayed on the liquid crystal display unit 26 or the like, or the in-vehicle speaker 71 or the like may be sounded via the voice synthesizer 60.

  Furthermore, the fare display device 20 acquires the audio signal output from the receiving unit 35 of the receiving device 30 directly from the receiving unit 35 or via the control unit 31, and the MPU 21 converts the audio signal into audio data (mp3, wav, (format such as wma) may be recorded in the data memory 24. For example, the recording start process is performed by the selection switch input permission process (S105, S115) shown in FIG. 6, and the recording end process is performed by the selection switch input prohibition process (S111) or the initialization process (S100). Thereby, since the contents of the emergency earthquake bulletin and the emergency warning broadcast are recorded, the broadcast contents received by the receiving device 30 can be confirmed afterwards.

  Further, the data memory 24 or a part thereof is constituted by a large-capacity dual port memory or the like so that so-called time-shifted reproduction can be performed with a predetermined time delay while recording (recording), and the reproduction output signal ( By inputting the audio signal) to the amplifying device 70, it is possible to make an announcement from the in-vehicle speaker 71 or the like after a predetermined time delay from the actual broadcast. In the case of this configuration capable of time-shift playback, a configuration in which switching to normal playback other than time-shift playback can be performed by operating a predetermined changeover switch, for example, from the receiving device 30 to actual broadcasting (live broadcasting). The crew member who is listening to can switch the announcement by live broadcasting from the in-vehicle speaker 71 as necessary. Thereby, the announcement by time shift reproduction and the announcement by live broadcasting can be selected timely.

  In the above-described embodiment, as shown in FIG. 6, when an emergency warning broadcast is received (S103; Yes), after the input of the switches 33d to 33g (selection switch) is permitted (S105), these switches 33d If there is an input of ~ 33g (S108; Yes), an emergency message corresponding to the input (for example, logo mark Ea shown in FIG. 8B) is displayed on the liquid crystal display unit 26, the destination display device 51, the on-boarding display device 53, However, even if there is no input from the switches 33d to 33g, an emergency message such as a preset logo mark Ea may be displayed on the liquid crystal display unit 26 or the like. good. Thereby, when the earthquake early warning is received by the receiving device 30, the logo mark Ea or the like is automatically displayed on the liquid crystal display unit 26 or the like even if the crew members do not input the switches 33d to 33g (selection switches). Can do.

  In addition, as a configuration of the fare display device 20 in which the audio signal from the receiving unit 35 is input from the receiving device 30, for example, by adding hardware or software capable of voice recognition processing by voice analysis technology, It is possible to analyze the content of the voice announcement from the included signal waveform or the like and convert it into text data. For this reason, based on such text data, the content of the announcement can be displayed as character information on each display device such as the liquid crystal display unit 26, the destination display device 51, and the on-board display device 53. In this case, the display control is performed by the GPU 25 or the like so that the character information for displaying the content flows and is displayed like a roll telop, and a certain amount of character information is repeatedly displayed. It can be reliably provided to passengers.

  Furthermore, based on such text data, the contents of the announcement can be used to determine “discipline (earthquake)”, “tsuyoyure (strong shaking)”, “tsunami (tsunami)”, “doshakzure (landslide)” and “nadare (avalanche)”. The keywords related to natural disasters such as “” can be extracted, and these extracted keywords and emergency messages set in advance (for example, the display shown in FIG. 8B, FIG. 9A, or FIG. 9B) By configuring the fare display device 20 so as to be associated with each other, the preset emergency message is displayed on the liquid crystal display unit 26 or the like without the input of the switches 33d to 33g (selection switches). You may comprise. Thereby, when the earthquake early warning or the emergency warning broadcast is received by the receiving device 30, even if there is no input of the switches 33d to 33g (selection switch) by the crew, FIG. 8 (B), FIG. 9 (A) and FIG. A logo mark Ea or the like as shown in FIG. 9B can be automatically displayed on the liquid crystal display unit 26 or the like.
