  A conventional building monitoring apparatus includes a personal computer, a display, a keyboard, a speaker, and the like. When an abnormality occurs in the building, the building monitoring apparatus generates an alarm and displays on the display that the alarm has newly occurred. In addition, when an abnormality occurs in the building, the building monitoring device sounds an alarm sound with a speaker to notify a user who monitors the inside of the building that an abnormality has occurred. This building monitoring apparatus makes it possible to determine, based on the timbre, that an alarm having a high importance level has occurred by changing the timbre of the alarm sound depending on the importance level of the alarm that notifies the abnormality.

  However, in the conventional building monitoring apparatus, for example, if the installed speaker is a stereo speaker, the same sound is emitted from the left (L) speaker and the right (R) speaker. This is because a monaural sound or a stereo sound that is the same sound on the left and right is ringing. Also, in the conventional building monitoring device, when a higher level alarm occurs when the alarm sound is sounded by the speaker, the alarm sound that is being sounded is stopped and then the higher level alarm sound is sounded again. It was. That is, in the conventional building monitoring apparatus, only the alarm sound with the highest importance is sounded.

  Also, the conventional building monitoring device does not stop the alarm sound that is ringing when the alarm sound is sounding through the speaker, and an alarm that is equal to or lower than the importance level of the alarm is ringing. The alarm will continue to sound. For this reason, the user has not been able to notice by the alarm sound that a new alarm has occurred.

FIG. 2 shows an example in which two alarm notification speakers 11 and 12 are provided. The alarm notification speakers 11 and 12 can simultaneously emit alarm sounds having different importance levels. When all the alarm notification speakers 11 and 12 ring and another alarm is generated, the duplication notification speaker 13 notifies the user of further alarm generation by ringing the notification sound.

  The alarm sound continues to sound repeatedly until the user presses the alarm sound stop button of the building monitoring device.

  FIG. 3 is a block diagram illustrating an example of a building monitoring apparatus according to the first embodiment.

  The building monitoring apparatus includes a determination unit 2, a storage unit 3, and a speaker control unit 4.

  The determination unit 2 determines whether an alarm is generated in the facility from the monitoring information received by the monitoring control device. Moreover, the determination part 2 determines the importance of the alarm which generate | occur | produced, when it determines with the alarm having generate | occur | produced in the installation. The importance of this alarm may be set arbitrarily. For example, the determination unit 2 can set the importance level of an alarm such as heavy, medium, light, and caution in descending order of importance.

  The storage unit 3 stores a plurality of alarm sounds and notification sounds. The plurality of alarm sounds correspond to the level of importance of the alarm and are sounded by either of the alarm notification speakers 11 and 12. The notification sound is generated by the overlapping notification speaker 13 to notify the user of further alarms.

  When one alarm is generated, the speaker control unit 4 reads the corresponding alarm sound from the storage unit 3 according to the importance level of the alarm determined by the determination unit 2. The speaker control unit 4 sounds the read alarm sound from any one of the plurality of alarm notification speakers 11 and 12.

  Moreover, the speaker control part 4 reads the alarm sound according to the importance of the alarm determined by the determination part 2 from the memory | storage part 3, when multiple alarms generate | occur | produce. The speaker control unit 4 sounds the read alarm sound from the plurality of alarm notification speakers 11 and 12, respectively. Here, the speaker control unit 4 outputs the alarm sound of the highest importance level from the left (L) alarm notification speaker 11 and then outputs the alarm sound of the next highest importance level from the right (R) alarm notification speaker 12. For example, an alarm sound may be output from a predetermined alarm notification speaker.

  In addition, the speaker control unit 4 determines the importance of the alarm determined by the determination unit 2 when the alarm notification speakers 11 and 12 have already sounded and an alarm having an importance level higher than the importance level of the alarm that is sounding has occurred. The alarm sound corresponding to the degree is read from the storage unit 3. The speaker control unit 4 stops the alarm sound having the lowest importance among the alarm sounds being sounded by the alarm notification speakers 11 and 12. The speaker control unit 4 sounds the read alarm sound from the alarm notification speakers 11 and 12 that have stopped.

  The speaker control unit 4 reads the notification sound from the storage unit 3 when the alarm notification speakers 11 and 12 have already sounded and an alarm having the same or lower importance than the alarm that has been sounded has occurred. The speaker control unit 4 sounds the read notification sound from the overlapping notification speaker 13.

  In addition, the speaker control unit 4 stops ringing of the alarm notification speakers 11 and 12 and the overlap notification speaker 13 according to an instruction from the user. For example, the ringing of the alarm notification speakers 11 and 12 and the duplicate notification speaker 13 is stopped by pressing a stop button displayed on the display by the user.

  Next, a method for sounding an alarm sound in the above configuration will be described.

  FIG. 4 is a flowchart illustrating an alarm sounding method in the building monitoring apparatus according to the embodiment.

  First, the speaker control unit 4 determines whether there are alarm notification speakers 11 and 12 that are ringing (step S41). When there is no alarm notification speaker 11 or 12 that is sounding (No in step S41), the speaker control unit 4 outputs an alarm sound corresponding to the importance of the alarm with any of the alarm notification speakers 11 and 12 that are not sounding. A ring is made (step S42). Moreover, the speaker control part 4 determines whether all the alarm notification speakers 11 and 12 are ringing, when there exists the alarm notification speakers 11 and 12 which are ringing (step S41 Yes) (step S43).

  When all the alarm notification speakers 11 and 12 are not ringing (No in step S43), the speaker control unit 4 causes the alarm notification speakers 11 and 12 that are not ringing to ring an alarm sound corresponding to the level of importance of the alarm. (Step S44). In addition, when all the alarm notification speakers 11 and 12 are sounding (Yes in Step S43), the speaker control unit 4 determines whether an alarm having a higher importance than the current alarm is sounding (Step S45). .

  The speaker control unit 4 stops the alarm sound of the alarm with the lowest importance among the sounding alarm sounds when the alarm having the same or lower importance as the current alarm is sounding (No in step S45). (Step S46). Further, the alarm sound of the current alarm is sounded by the alarm notification speakers 11 and 12 stopped in step S46 (step S47). When the alarm having a higher importance than the current alarm is sounding (Yes in Step S45), the speaker control unit 4 causes the duplication notification speaker 13 to sound a notification sound for notifying the occurrence of further alarm (Step S48). ).

  According to the alarm sounding method, the building monitoring device can simultaneously sound a plurality of alarm sounds even when a plurality of alarms having different importance levels are generated. Further, the building monitoring apparatus can notify the user that a new alarm has been generated by the duplication notification speaker 13 even if all the alarm notification speakers 11 and 12 are ringing.

  Therefore, according to the first embodiment, the building monitoring apparatus can notify the user that a plurality of alarms having different importance levels have occurred.

With the configuration of the multi-channel alarm notification speakers 51 to 5N illustrated in FIG. 5, the building monitoring apparatus can simultaneously generate alarm sounds for the number of installed channels. Here, the speaker control unit 4 outputs the alarm sound of the highest importance level to the first channel alarm notification speaker 51 and the next highest level alarm sound to the alarm notification speaker 52 of the second channel for the currently occurring alarm. Then, the alarm sound with the second highest importance may be sounded to one alarm notification speaker for each importance, such as to the alarm notification speaker 53 of the third channel.

  Further, the speaker control unit 4 reads out the notification sound from the storage unit 3 when the alarm notification speakers 51 to 5N have already sounded and an alarm having an importance level equal to or lower than the importance level of the alarm being generated is generated, The read notification sound is generated from the overlap notification speaker 13.

  Moreover, in the said building monitoring apparatus, although the alarm sound is sounded by either of the alarm alert speakers 51-5N, you may sound the corresponding alert alert speaker 51-5N for every importance of an alarm.

  FIG. 6 is a flowchart illustrating an example of a processing procedure for ringing the corresponding alarm notification speakers 51 to 5N for each importance level of the alarm. As shown in FIG. 6, the speaker control unit 4 performs an alarm sounding process (step S61).

  FIG. 7 is a flowchart showing an example of the alarm sounding processing procedure shown in FIG. As shown in FIG. 7, the speaker control unit 4 determines whether the same alarm sound as the current importance level is sounding from the predetermined alarm notification speakers 51 to 5N (step S71). When the same alarm sound as the current importance level is not ringing on the predetermined alarm notification speakers 51 to 5N (No in step S71), the speaker control unit 4 selects the alarm sound speakers 51 to 51 corresponding to the current importance level of the alarm. 5N is sounded (step S72). When the same alarm sound as the current importance level is sounding from the predetermined alarm notification speakers 51 to 5N (Yes in step S73), the speaker control unit 4 reads the notification sound from the storage unit 3, and reads the read notification sound. It is made to ring from the overlapping notification speaker 13. (Step S73).

  According to the above configuration, the building monitoring apparatus includes a plurality of alarm notification speakers and duplicate notification speakers, and controls the sounding of the alarm sound by the speaker control unit. Thereby, the building monitoring apparatus can sound an alarm sound having a different importance for each alarm sound speaker. In addition, the building monitoring apparatus can notify the user that a new alarm has been generated by the duplicate notification speaker even if all the alarm notification speakers are ringing.

  Therefore, also in the second embodiment, the building monitoring apparatus can notify the user that a plurality of alarms having different importance levels have occurred. Furthermore, according to the second embodiment, the building monitoring apparatus can notify that a new alarm has occurred with a notification sound even if the alarm sound is sounding on all speakers.

  In the multi-channel speaker configuration, when alarms of the same importance level are generated at the same time, the speaker control unit 4 may simultaneously sound an alarm sound of the same importance level in each of the plurality of alarm notification speakers in a surround manner. . Thereby, the building monitoring apparatus can notify the user that a new alarm has been generated by the sound of sound using surround sound that is pseudo three-dimensional sound.
