Description

  The present invention relates to an abnormality notification device, and more particularly to a device that notifies an abnormality of a power supply means by voice.

  2. Description of the Related Art Conventionally, for example, there is one disclosed in Patent Document 1 for notifying an abnormality of a power supply means by voice. In the technique of Patent Document 1, in a power supply system in which DC power generated by a solar cell installed on a roof or the like is converted into AC power by a power conditioner installed on the attic or the like, temperature sensors, currents are provided at various points in the system. Various detection means such as a sensor and a voltage sensor are provided, and system abnormality is constantly monitored by these detection means. When the detection means detects an abnormality, the fact that the abnormality has been detected is reported to a control unit installed in the living room or the like. The control unit examines the content of the reported abnormality, creates audio data indicating the content of the abnormality and its target, and is loudened from the speaker.

Japanese Patent Application Laid-Open No. 11-119846

  In such an abnormality notification device, since the power conditioner is installed in the attic of one house and the control unit is installed in the living room, the distance between the two is relatively short, and the detection signal from the detection means is transmitted to the control unit. It's easy to do. However, such an abnormality notification device, for example, the power supply means of a television broadcast retransmitting device installed at the top of a mountain or the like, and a control unit at a position of a supervisor far away from the retransmitting device. When a cable is provided, it is necessary to lay a cable for transmitting a detection signal over a long distance. Also, depending on the type of detection means, an abnormality may be detected at the same time. For example, when a power failure detection means and a power supply output voltage detection means are provided as detection means, the power failure output means and the output voltage detection means are not generated due to the occurrence of a power failure. And detect abnormalities at the same time. Thus, Patent Document 1 does not show any countermeasures when a plurality of abnormalities occur at the same time.

  SUMMARY OF THE INVENTION An object of the present invention is to provide an abnormality notification device that does not need to lay a cable at a distant position and that outputs a sound regarding an abnormality having a high priority when a plurality of abnormalities occur.

  The abnormality notification device of one embodiment of the present invention includes power supply means for electronic equipment. The power supply means for the electronic device is installed at a location away from the location of the supervisor. For example, it is installed at the top of a mountain. The power supply means includes a plurality of different abnormality detection means. For example, a power failure detection means for detecting that the power supply to the power supply is cut off, a voltage detection means for detecting that the power supply output voltage is lower than the voltage reference value, or a power supply output current lower than the current reference value. There is a current detecting means for detecting the decrease. These detecting means may detect an abnormality at the same time. An abnormality detection signal from the detection means is supplied to the control means. When a plurality of abnormality detection signals are supplied at the same time, the control unit selects one of the plurality of abnormality detection signals according to a predetermined priority and outputs audio information corresponding to the selected abnormality detection signal. . A transmitting unit modulates a carrier wave of a predetermined frequency with the audio information output from the control unit, and wirelessly transmits the modulated carrier wave. For example, the priority is set higher as the priority needs to be dealt with immediately.

  According to the abnormality notification device configured as described above, the abnormality information is transmitted wirelessly, so there is no need to lay a cable between the reception means. In addition, when a plurality of abnormalities are detected at the same time, abnormal information having a high priority is transmitted, so that the abnormalities can be dealt with quickly.

  When the abnormality detection signal newly supplied has a high priority in a state where the abnormality detection signal has already been supplied, the control means corresponds to the sound corresponding to the already supplied abnormality detection signal. Instead of the information, the audio information corresponding to the newly supplied abnormality detection signal can be supplied to the transmission means.

  Even if an abnormality has already occurred, if there is an abnormality that needs to be dealt with more quickly than that abnormality, that is, an abnormality with a higher priority, audio information representing this abnormality with a higher priority Is output.

  The transmission means may start to operate when the abnormality detection signal is supplied to the control means. If comprised in this way, since a transmission means will operate | move only when abnormality is detected, the power consumption in normal time can be suppressed.

  The predetermined frequency may be a frequency that can be received by an FM receiver, and the modulation of the carrier wave may be FM modulation. If comprised in this way, it is not necessary to install a special receiver specially, and it can know that abnormality has arisen with the FM receiver marketed.

  The power supply means for the electronic device is supplied with a pre-processing means for pre-processing a television broadcast signal for retransmission, for example, a head amplifier device or a television broadcast signal processed by the pre-processing means. It can be a power supply means of a re-transmission means that processes and re-transmits. Television broadcast signal pre-processing means and re-transmission means are generally installed in a place where people are not frequently frequented. If there is an abnormality at the same time, or if an abnormality occurs in the state where the abnormality has occurred, wireless transmission of the fact that a high-priority abnormality that needs to be dealt with immediately is occurring By this, it is possible to easily notify the monitor at a remote position.

  As described above, according to the abnormality notification device according to the present invention, when a plurality of abnormalities occur, it is possible to output a voice regarding a high priority abnormality, and the notification is separated from the installation location of the abnormality notification device. You can know the location without preparing any special equipment.

It is a figure which shows the head amplifier apparatus which provides the abnormality alerting device of FIG. 1, and the re-transmission apparatus used with this. It is a figure which shows the table and memory | storage register which are used in the abnormality alerting | reporting apparatus of FIG. It is a flowchart which shows the process which CPU16 of FIG. 1 performs.

  As shown in FIG. 2, the abnormality notification device according to one embodiment of the present invention is provided in a retransmission means for television broadcasting, for example, the retransmission device 2. The re-transmission device 2 is installed in a high place in the vicinity of a difficult viewing area for television broadcasting, for example, on a flat ground near a mountain. A pre-processing means, for example, a head amplifier device 4 is installed on the top of the mountain. In the head amplifier device 4, a television broadcast signal from a broadcasting station received by the receiving antenna 5 is subjected to processing such as amplification, and is transmitted to the retransmitting device 2 via a transmission path, for example, a coaxial cable or an optical fiber 6. The re-transmission device 2 performs processing such as amplification on the transmitted television broadcast signal and the like, and re-radiates it to the difficult viewing area by the transmission antenna 10. In FIG. 2, one re-transmission device 2 is shown for the head amplifier device 4, but a plurality of re-transmission devices 2 may be provided for the head amplifier device 4 via branch distribution means. is there.

  As shown in FIG. 1, the head amplifier device 4 has power supply means for electronic equipment, for example, a power supply device 12. The power supply device 12 includes, for example, an AC-DC conversion unit that rectifies and smoothes AC power from a commercial AC power source and converts it into DC power. The DC power from the AC-DC conversion unit is converted into the head amplifier device 4. Supply to each component. The power supply device 12 also includes an uninterruptible power supply unit, and supplies DC power from the uninterruptible power supply unit to each component of the head amplifier device 4 over a certain period of time when the commercial AC power supply fails. To do. The uninterruptible power supply unit includes an internal battery and an external battery, and further includes a charging circuit for charging the internal battery and the external battery with DC power obtained from the AC-DC conversion unit.

  The power supply device 12 is provided with a plurality of, for example, five different detection means. For example, a built-in battery abnormality detector A for detecting whether or not an abnormality has occurred in the internal battery provided in the uninterruptible power supply unit is provided, and whether or not an abnormality has occurred in the external battery provided in the uninterruptible power supply unit is determined. An external battery abnormality detector B for detection is provided. Further, a charging circuit abnormality detector C is provided for detecting whether or not an abnormality has occurred in the charging circuit for charging the built-in battery and the external battery. Moreover, the power failure detector D which detects whether the power failure has generate | occur | produced in the installation place of the power supply device 12 is provided. Further, an AC-DC conversion unit abnormality detector E for detecting whether or not an abnormality has occurred in the AC-DC conversion unit is provided. As an abnormality detector of the AC-DC conversion unit, an output voltage abnormality detector that detects that the output voltage is output only at a voltage lower than a predetermined reference output voltage, or an output current is predetermined. An output current abnormality detector that detects that an output of only a current lower than the reference output current is abnormal, an input voltage abnormality detector that detects that the input voltage is lower than a predetermined reference input voltage, An input current abnormality detector that detects that the input current is lower than a predetermined reference input current as an abnormality can be provided individually.

  Each of the detectors A to E has contacts 14a, 14b, 14c, 14d, and 14e corresponding to the detectors A to E, respectively. One end of each of the contacts 14a to 14e is connected to a control unit, for example, the CPU 16, and the other end is connected to a reference potential point, for example, a ground potential point. And each contact 14a thru | or 14e is OFF when the corresponding detector A thru | or E has not detected abnormality, and if there was what detected abnormality among each detector A thru | or E, the abnormality was detected. The contact corresponding to the detector is turned on. For example, when the charging circuit abnormality detector C detects an abnormality, the contact 14c is closed. As a result, an abnormality detection signal that is a ground potential is supplied to the CPU 16.

  The CPU 16 is provided with sound generating means, for example, a sound ROM 18. The audio ROM 18 stores audio information representing an abnormality detected by each of the detectors A to E, for example, an audio signal. For example, in response to the abnormality detection of the detector A, an audio signal “an abnormality has occurred in the built-in battery” is stored, and in response to the abnormality detection of the detector B, “an abnormality has occurred in the external battery. Is stored, and in response to the detection of the abnormality of the detector C, an audio signal of “There is an abnormality in the charging circuit.” Corresponding to the abnormality detection, a voice signal saying “A power failure has occurred at the installation location” is stored, and in response to the abnormality detection by the detector E, “An abnormality has occurred in the AC-DC conversion unit. Is stored. "

  As will be described later, the CPU 16 selects an audio signal corresponding to a closed one of the contacts 14a to 14e and supplies it to a transmission means, for example, the FM modulation IC 20. The FM modulation IC 20 modulates the carrier wave with an audio signal, supplies the FM modulated signal to the transmission antenna 22 provided in the retransmitting apparatus 2 via the transmission line 6, and transmits it. The carrier frequency is determined by a frequency selection switch 26 connected to the CPU 16 in order to make the frequency modulated in the frequency band in which this FM modulated signal can be received by a commercially available FM receiver 24 available. The FM receiver 24 is installed, for example, at a monitoring station located away from the place where the retransmission apparatus 2 is installed.

  As shown in FIG. 3A, the CPU 16 stores a table in which priorities for the detectors A to E are determined in advance. In this embodiment, the power failure detection by the detector D has the highest priority, the internal battery abnormality detection by the detector A, the AC-DC conversion unit abnormality detection by the detector E, and the charging circuit abnormality detection by the detector C. The priority is set lower in the order of the abnormality detection of the external battery by the detector B.

  As described above, the abnormality notification device 11 is configured by the CPU 16, the audio ROM 18, the FM modulation IC 20, and the frequency selection switch 26.

  The CPU 16 performs processing according to a flowchart as shown in FIG. 4, for example. This process is started when one of the contacts 14a to 14e is closed. In this process, first, the on / off states of the contacts 14a to 14e are read (step S2). Thus, for example, as shown in FIG. 3B, the CPU 16 stores the on / off states of the respective contacts 14a to 14e in a storage means, for example, a memory attached to the CPU 16. At this time, a plurality of contacts may be turned on simultaneously depending on the type of abnormality. For example, when a power failure occurs, the AC-DC conversion unit does not generate any output, so the detector D that detects the power failure and the detector E that detects an abnormality of the AC-DC conversion unit detect the abnormality and contact 14d. , 14e are turned on. Alternatively, an abnormality may already be detected, and in addition to this, an abnormality may be newly detected. For example, an abnormality of the charging circuit may be further detected in a state where the abnormality of the built-in battery has been detected first.

  Next, the CPU 16 determines the contact with the highest priority among the contacts that are turned on with reference to the table shown in FIG. 3A (step S4). For example, when the contacts 14d and 14e are on as described above, the contact 14d having a high priority is selected. When there is one contact that is turned on, the contact that is turned on is selected as it is.

  Subsequently, it is determined whether there is a voice that has already been output (step S6). If the answer to this determination is no, the audio signal corresponding to the selected contact is loop-outputted to the FM modulation IC 20, that is, repeatedly supplied, and at the same time, the FM modulation IC 20 is operated to store the audio output, and This process is terminated (step S8). The carrier wave of the frequency selected by the frequency selection switch 26 is FM-modulated with the selected audio signal to generate an FM modulated signal, and this FM modulated signal is provided in the retransmission apparatus 2 via the transmission path 6. 22 and transmitted from the transmission antenna 22. Until now, the FM modulation IC 20 does not operate while the FM modulation signal is not generated. When the audio signal is supplied for the first time, the FM modulation IC 20 starts operating. As a result, when there is no abnormality, no power is consumed in the FM modulation IC 20 of the head amplifier device 4, and the power consumption of the head amplifier device 4 can be suppressed. Further, since the audio signal is output in a loop, it is not necessary for the supervisor to always receive it by the FM receiver 24, and an abnormality has occurred by receiving it by the FM receiver 24 after an appropriate time. I can know that.

  If the answer to the determination in step S6 is yes, since the FM modulation signal for notifying some abnormality has already been output from the FM modulation IC 20, it has been selected after the end of one loop of the currently output audio signal. An audio signal corresponding to the contact is output as a loop to the FM modulation IC 20 to store that the audio is output (step S10), and this process is terminated. Therefore, if an abnormality having a higher priority than the conventional abnormality has occurred in the state where some abnormality has already been detected and the FM modulation signal based on the audio signal corresponding to the abnormality has been transmitted. Repeatedly informed.

  If the contact selected in step S4 is the same as the contact already selected, or if the priority is lower than the contact already selected, it is selected first in step S10. The same audio signal as the received audio signal is supplied to the FM modulation IC 20.

  In the above embodiment, the abnormality of the power supply device 12 of the head amplifier device 4 is detected, and the abnormality information is wirelessly transmitted in the FM frequency band from the transmission antenna 22 of the retransmission transmission device 2 away from the head amplifier device 4. However, the above-described abnormality notifying device 11 is provided in the retransmitting device 2, and the output of the FM modulation IC 20 is configured to be supplied to the transmitting antenna 22 of the retransmitting device 2. It is also possible to perform radio transmission from the transmission antenna 22 of the retransmission apparatus 2. Further, the abnormality notification device 11 is provided in each of the head amplifier device 4 and the retransmission device 2, and the output of the FM modulation IC 20 of the abnormality notification device 11 of the head amplifier device 4 is transmitted via the transmission path 6 to the transmission antenna 22 of the retransmission device 2. And the output of the 11 FM modulation IC 20 of the abnormality notification device of the retransmitting device 2 is supplied to the transmitting antenna 22 so as to notify the abnormality of the power supply device of the head amplifier device 4 and the retransmitting device 2. You can also. In this case, the frequency of the FM modulation signal of the FM modulation IC 20 of the head amplifier device 4 is different from that of the FM modulation signal of the FM modulation IC 20 of the retransmitting device 2. In the above embodiment, the abnormality notification device 11 for the power supply device of the retransmitting device 2 and the head amplifier device 4 is shown. However, the present invention is not limited to this, but an electronic device installed in a remote place, for example, joint reception The present invention can also be used when detecting an abnormality in a power supply device that supplies operating power to a relay amplifier connected to a coaxial cable for transmission in a facility via the coaxial cable.

  In the above embodiment, the CPU 16 performs the process as shown in FIG. 4, but is not limited to this. For example, the following process is performed every time one of the contacts 14 a to 14 e is turned on. You can also. That is, when a certain contact is turned on, it is determined whether there is a sound that has already been output as in step S6. If the answer is no, step S8 is executed and the process is terminated. If the answer to the determination in step S6 is yes, it is determined whether the priority of the contact that was turned on this time is higher than the contact that corresponds to the audio signal that has already been output. If the answer is yes, the answer is yes. The audio signal corresponding to the contact point is supplied to the FM modulation IC 20 and the same process as in step S10 is performed. If no, the process is terminated.
