DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the drawings.
FIG. 1 is a configuration diagram of a door-to-door receiver according to a first embodiment of this invention.
1 includes an antenna 1 that receives a radio signal from a master station, a radio unit 2 that demodulates a radio signal input from the antenna 1, and a control signal such as a paging signal from the signal of the radio unit 2 The control unit 3 that controls each unit, the audio control unit 4 that converts the radio signal demodulated by the radio unit 2 into an audio signal, the audio amplification unit 5 that amplifies the audio signal from the audio control unit 4, and the audio A speaker 6 that outputs an audio signal from the amplification unit 5, an operation unit 7 that performs operations such as volume adjustment, an outlet 8 that supplies power, a battery 9 that supplies power during a power failure, and an outlet when energized 8 includes a power supply unit 10 that outputs power from the battery 9 and outputs power from the battery 9 in the event of a power failure, and detects a battery voltage of the battery 9, and a display unit 11 that displays a status display and an alarm display.
[0018]
The alarm notification operation of the first embodiment of the door-to-door receiver will be described. In the first embodiment, when an alarm event with low urgency occurs, the operation is performed when the volume of the notification sound is reduced. The operation of alarm notification when the battery voltage drops will be described below as an example with reference to FIG. FIG. 2 is a flowchart of the alarm notification operation when the battery voltage drops.
[0019]
First, the battery voltage of the battery 9 is measured by the power supply unit 10 (STEP 1). When it is determined that the battery voltage of the battery 9 is equal to or lower than a predetermined voltage value (STEP 2), the battery voltage of the power supply unit 10 has decreased. To the control unit 3.
Receiving the notification that the battery voltage has dropped, the control unit 3 causes the display unit 11 to display that the battery voltage has dropped (STEP 3), and further the battery voltage drop is urgent using a table or the like. It is judged whether the alarm event is a high degree (STEP 4).
[0020]
For example, when determining the urgency level of an alarm event, it is conceivable to determine the urgency level of the notified alarm event by providing the control unit 3 with a table as shown in FIG. For example, alarm events with low urgency include low battery voltage, AC power outage 8, reception of broadcasts with low urgency, and broadcasts from a master station recorded in a door-to-door receiver. Unreproduced and the like. Moreover, examples of alarm events with a high degree of urgency include non-replay of a broadcast with a high degree of urgency.
[0021]
Here, since the battery voltage drop is a low urgency alarm event, the control unit 3 controls the voice control unit 4 and the voice amplification unit 5 to output a notification sound or voice at a small volume for a certain time (STEP 5). ). Then, the door-to-door receiver enters a standby state (STEP 7).
[0022]
Thus, in the first embodiment, in the case of an alarm event with a low degree of urgency, a notification sound is output at a low volume when an alarm event occurs. Thereby, when an alarm event with a low degree of urgency occurs, it is possible to minimize the trouble to the user due to the ringing at midnight or the like.
[0023]
In the first embodiment, in the case of an alarm event with a low degree of urgency, the notification sound is output at a small volume. However, the present invention is not limited to this, and the ringing time may be shortened or the notification is performed. The sound may be stopped and only the alarm display by the display unit 11 may be displayed. Furthermore, as another modification, the broadcast from the master station may not be broadcast except for broadcasts with high urgency.
[0024]
Next, the alarm notification operation of the individual receiver according to the second embodiment will be described. In the second embodiment, immediately after receiving the broadcast, the alarm information of the individual receiver is detected and notified. In the following, the operation of the second embodiment will be described with reference to FIG. 4, taking as an example the alarm notification operation when the battery voltage drops.
[0025]
FIG. 4 is a flowchart of the alarm notification operation when the battery voltage drops in the second embodiment. The configuration of the door-to-door receiver itself is the same as that of the door-to-door receiver according to the first embodiment shown in FIG. 1, and the description thereof is omitted here.
[0026]
The door-to-door receiver stands by in a standby state in a state where it can receive a broadcast from the master station (STEP 10). When the antenna 1 receives the radio signal from the master station, the control unit 3 determines whether the radio signal is for the own station based on the demodulated signal from the radio unit 2 (STEP 11). If it is a radio signal, the control unit 3 controls the audio control unit 4 and the audio amplification unit 5 to output a broadcast from the master station via the speaker 6 (STEP 12).
[0027]
When the broadcast from the master station is finished, alarm information is detected next. The alarm information to be detected includes a decrease in battery voltage, AC power failure, presence / absence of unreproduced broadcast recorded on the recording device of the door-to-side receiver, and the like. In order to detect the battery voltage, the power supply unit 10 measures the battery voltage of the battery 9 (STEP 13). If it is determined that the battery voltage of the battery 9 remains lower than the predetermined voltage value, the power supply unit 10 notifies the control unit 3 that the battery voltage is decreasing (STEP 14).
Receiving the notification, the control unit 3 causes the display unit 11 to display that the battery voltage has decreased (STEP 15), and further controls the audio control unit 4 and the audio amplification unit 5 to generate a notification sound or audio. Output is performed for a certain time (STEP 16), and the individual receiver is in a standby state (STEP 17).
[0028]
Thus, in the second embodiment, immediately after the broadcast from the master station is performed, the alarm event of the individual receiver is detected, and if the alarm event occurs, the notification sound is output. ing. As a result, the user can be alerted by the notification sound at the timing when the user pays attention to the output of the door-to-side receiver immediately after the broadcast from the master station is performed, and the user can easily notice the alarm event. be able to.
In addition, since the broadcast from the master station is normally controlled so as not to be transmitted at midnight except for emergency information, there is no problem of inconvenience to the user due to ringing at midnight or the like.
[0029]
Next, the alarm notification operation of the door-to-door receiver according to the third embodiment will be described using the alarm notification operation at the time of battery voltage drop as an example. The third embodiment is a combination of the first embodiment and the second embodiment.
FIG. 5 is a flowchart of the alarm notification operation at the time of decrease in the third embodiment. The configuration of the door-to-door receiver itself is the same as that of the door-to-door receiver according to the first embodiment shown in FIG. 1, and the description thereof is omitted here.
[0030]
First, the battery voltage of the battery 9 is measured by the power supply unit 10 (STEP 1). When it is determined that the battery voltage of the battery 9 is equal to or lower than the predetermined voltage value (STEP 2), the battery voltage of the power supply unit 10 has decreased. To the control unit 3.
Receiving the notification that the battery voltage has dropped, the control unit 3 causes the display unit 11 to display that the battery voltage has dropped (STEP 3), and further the battery voltage drop is urgent using a table or the like. It is judged whether the alarm event is a high degree (STEP 4).
[0031]
For example, when determining the urgency level of an alarm event, it is conceivable to determine the urgency level of the notified alarm event by providing the control unit 3 with a table as shown in FIG. Low urgency alarm events include battery voltage drop, AC power outage 8, reception of low urgency broadcasts, and broadcasts from the master station recorded in the door-to-door receivers. For example, reproduction.
[0032]
Since the battery voltage drop is an alarm event with a low degree of urgency, the control unit 3 controls the voice control unit 4 and the voice amplification unit 5 to output a notification sound or voice at a small volume for a predetermined time (STEP 5). The receiver enters a standby state (STEP 7).
[0033]
After that, when the antenna 1 receives a radio signal from the master station, the control unit 3 determines whether the radio signal is for the own station based on the demodulated signal from the radio unit 2 (STEP 11). If it is a radio signal, the control unit 3 controls the audio control unit 4 and the audio amplification unit 5 to output a broadcast from the master station via the speaker 6 (STEP 12).
[0034]
When the broadcast from the master station is finished, alarm information is detected next. The alarm information to be detected includes a decrease in battery voltage, AC power failure, presence / absence of unreproduced broadcast recorded on the recording device of the door-to-side receiver, and the like. In order to detect the battery voltage, the power supply unit 10 measures the battery voltage of the battery 9 (STEP 13).
If it is determined that the battery voltage of the battery 9 remains lower than the predetermined voltage value, the power supply unit 10 notifies the control unit 3 that the battery voltage is decreasing (STEP 14). Receiving the notification, the control unit 3 causes the display unit 11 to display that the battery voltage has decreased (STEP 15), and further controls the audio control unit 4 and the audio amplification unit 5 to generate a notification sound or audio. Output is performed for a certain time (STEP 16), and the individual receiver is in a standby state (STEP 17).
[0035]
As described above, in the third embodiment, when an alarm event with low urgency occurs, a notification sound is output at a low volume, and then the alarm event is detected again immediately after the broadcast from the master station is performed. If the alarm event has not been resolved, a notification sound is output at a high volume. As a result, when an alarm event with low urgency occurs, a notification sound is sent at the timing when the user pays attention to the output of the individual receiver immediately after the broadcast from the master station is performed, even if the user does not notice it. The user can be alerted by an alarm, and the user can easily notice the alarm event.
[0036]
Further, when an alarm event with low urgency occurs, the sound of the midnight sound can be reduced by reducing the volume of the alarm sound, shortening the alarm time, or stopping the alarm sound and only displaying the alarm on the display unit 11. It is possible to minimize the trouble to the user due to the above.
[0037]
Next, the alarm notification operation when the battery voltage of the door-to-door receiver according to the fourth embodiment of the present invention is lowered will be described with reference to FIG. In the fourth embodiment, an alarm management table is provided in an individual receiver, and when an alarm occurs, a notification is given, and a flag is set in the alarm management table. By referring, when there is an alarm, it notifies.
The operation of the fourth embodiment will be described below with reference to the flowchart of FIG. The configuration of the door-to-door receiver itself is basically the same as that of the door-to-door receiver according to the first embodiment shown in FIG. 1, but differs in that the control unit 3 has an alarm table as shown in FIG. ing.
[0038]
First, the battery voltage of the battery 9 is measured by the power supply unit 10 (STEP 1), and when it is determined that the battery voltage of the battery 9 is equal to or lower than a predetermined voltage value, the power supply unit 10 determines that the battery voltage has decreased. 3 is notified (STEP 2). Receiving the notification that the battery voltage has dropped, the control unit 3 sets a flag indicating that the battery voltage has dropped in the alarm management table shown in FIG. 7 (STEP 21).
[0039]
FIG. 7 is an example of an alarm management table, and a flag indicating whether or not an alarm is generated can be set for each alarm item. FIG. 7 shows the state of the flag when the battery voltage drops. Other alarm flags for battery voltage drop include AC power failure, broadcast reception from the master station, non-replay of broadcast from the master station recorded in the door-to-door receiver, and the like. This flag is periodically checked, and is released when a problem such as battery replacement is solved.
[0040]
Further, the control unit 3 causes the display unit 11 to display that the battery voltage has decreased (STEP 3), and further uses a table or the like to determine whether the battery voltage decrease is a highly urgent alarm event. Judgment is made (STEP 4).
[0041]
For example, when determining the urgency level of an alarm event, it is conceivable to determine the urgency level of the notified alarm event by providing the control unit 3 with a table as shown in FIG. Low urgency alarm events include battery voltage drop, AC power outage 8, reception of low urgency broadcasts, and broadcasts from the master station recorded in the door-to-door receivers. For example, reproduction.
[0042]
Since the battery voltage drop is a low-urgency alarm event, the control unit 3 controls the voice control unit 4 and the voice amplification unit 5 to output a notification sound or voice at a small volume for a certain time (STEP 4). The receiver enters a standby state (STEP 5). Although the notification sound is output at a low volume, the ringing time may be shortened or no notification sound may be output at all as in the case of the first embodiment. .
[0043]
After that, when the antenna 1 receives a radio signal from the master station, the control unit 3 determines whether the radio signal is for the own station based on the demodulated signal from the radio unit 2 (STEP 11). If it is a radio signal, the control unit 3 controls the audio control unit 4 and the audio amplification unit 5 to output a broadcast from the master station via the speaker 6 (STEP 12).
[0044]
When the broadcast from the master station is completed, the control unit 3 checks whether a flag indicating an alarm event is set (STEP 22). If the alarm event is not resolved and the flag set in STEP 21 remains on, the control unit 3 controls the voice control unit 4 and the voice amplification unit 5 to output a notification sound or voice for a predetermined time (STEP 16). ), The door-to-door receiver enters a standby state (STEP 17).
[0045]
As described above, in the fourth embodiment, in the case of an alarm event with low urgency, when an alarm event occurs, a notification sound is output at a low volume and a flag indicating that the alarm event has occurred is set. Immediately after the broadcast from the station is performed, a flag indicating an alarm event is checked, and if the alarm event is not resolved, a notification sound is output at a high volume.
As a result, in the fourth embodiment, in addition to the effects of the third embodiment, immediately after the broadcast from the master station is performed, the alarm occurrence state can be grasped only by referring to the alarm management table. Therefore, as compared with the third embodiment, there is also a secondary effect that it is possible to grasp the current alarm occurrence state in a short time and notify the user.
[0046]
Although the present embodiment has been described by taking a decrease in battery voltage as an example, the present invention is not limited to a decrease in battery voltage, and abnormalities in each element constituting the individual receiver such as a power failure Needless to say, it is also useful for notification when the broadcast is received from the master station, or when the recorded broadcast content is not reproduced.
[0047]
As described above, in the embodiment of the present invention, in the case of an alarm event with low urgency, when an alarm event occurs, a notification sound is output at a low volume, and then immediately after broadcasting from the master station is performed, If the alarm event has not been resolved, the notification sound is output at a high volume.
[0048]
As a result, the user can be alerted by a notification sound at the timing when the user pays attention to the output of the door-to-side receiver immediately after the broadcast from the master station is performed, and the user can easily notice the alarm event. be able to. In addition, when an alarm event with low urgency occurs, it is possible to reduce the volume of the alarm sound, shorten the ringing time, or stop the alarm sound and display only the alarm on the display unit. It is also possible to minimize the inconvenience to the user.
[0049]
For this reason, in order to avoid annoying the user due to ringing at midnight, etc., the fear that the user will not notice the emergency broadcast is eliminated by stopping the alarm sound or reducing the volume. .
[0050]
【The invention's effect】
As described above in detail, according to the present invention, the user is notified of the abnormality of the component at the timing when the user pays attention to the door-to-door receiver after the end of the broadcast from the master station. On the other hand, the abnormality of the component can be easily noticed.
