Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to an onboard audio warning system that uses audio to notify abnormalities. It is a system that replaces audio warnings without changing the system, and is applicable to all ships that employ monitoring of engine equipment or systems using data loggers or monitors.

Furthermore, since it can be applied to land-based plants using data loggers, monitors, etc. that perform intensive monitoring as described above, it can also be used for similar systems in other industries, regardless of ships.

[Prior Art] FIG. 2 shows a conventional ship engine warning system. An abnormality at a detection point in the engine part is detected by an engine part monitor or a data logger b via a sensor etc. a,
The detected abnormality is output as a warning inside the ship by the buzzer c. Also, during unmanned operation such as at night, alarms are output only from the buzzer alarm from the extended alarm panel d and from the grouped lamps (for example, M/E related, boiler, others, etc.).

However, in the above-mentioned ship engine department alarm system, the alarm recognition work is performed using a buzzer alarm, so the operator has to visually confirm which abnormality has occurred after hearing the buzzer alarm. Particularly during unmanned operation, such as at night, a warning is output only by the extended warning panel and the grouped lamps, making it even more complicated to check the contents of the warning.

Therefore, it would be extremely convenient if the buzzer alarm could be replaced with an audio alarm that allows the content of the alarm to be immediately confirmed. In this regard, an ``audio warning system'' has already been proposed (1986-
(No. 146454), but this device is a device itself and has not been systemized, so it cannot be used to immediately configure an inboard audio warning system.

[Problems to be solved by the invention] As mentioned above, the conventional shipboard engine warning system uses a buzzer alarm, so the task of recognizing abnormalities is complicated. For this reason, it is conceivable to make the buzzer warning audible, but the existing audible shipboard warning systems have not been systemized.

Therefore, the purpose of the present invention is to systemize a ship's internal warning system by widely incorporating it into a part of the ship's warning system without limiting it to the engine section, and by replacing the buzzer warning with an audio warning,
It is an object of the present invention to provide an onboard audio warning system that solves the above-mentioned conventional problems, reduces the complicated work of recognizing abnormalities, and enables highly efficient work of onboard engineers.

[Means for Solving the Problems] The inboard audio warning system of the present invention includes a detection section that detects an abnormality in the inboard engine section, a detection signal from the detection section to detect an engine abnormality point, and displays the details of the abnormality. A control section in the central control room that outputs alarm signals, an extended alarm panel in the engine section for each room and public room, and an extended alarm panel in the wheelhouse that displays an extended display of the above-mentioned abnormalities and outputs a buzzer alarm based on the alarm signal from the control section. In an inboard engine abnormality warning system equipped with a steering console, the control unit, the steering console, and each engine extension alarm panel are each provided with a speaker for outputting an audio warning, and the control unit is equipped with a speaker that outputs an audio warning during unmanned operation. The engineer selection means for selecting the speaker that should output the alarm is combined with the audio data registered internally in response to the alarm signal from the control unit, and creates audio output according to the content of the abnormality. An audio warning device is provided which outputs an output to the speaker via a selection means.

[Operation] During unmanned operation, an abnormal point detected by the control unit via the detection unit is replaced by an audio warning by the audio warning output device, and a message about the abnormality is output from the speaker.

At this time, the engineer selection means selects the speaker, so that only the necessary speakers among the speakers of the control section, steering console, and each engine section extension alarm panel output sound.

[Example] An example of the present invention will be described below based on FIG.

FIG. 1 shows an example of the in-ship audio warning system of the present invention.
Although only engine department alarms are dealt with here, it can also be applied to other shipboard alarms, such as fire alarms, deck/cargo handling related alarms, vessel maneuvering alarms, collision prevention alarms, etc.

The shipboard audio warning system is a system that incorporates the audio shipboard warning system (Utility Application No. 60-31042) into a part of the existing engine department warning system. output device 3,
It mainly consists of a buzzer, a speaker 4, a changeover switch 5, etc.

The detection section 1 consists of a sensor group 1a, and detects the state of each measurement point of the engine section in the form of an electrical signal.

The control unit 2 consists of a data logger or monitor 6a built into the engine control console 6, and obtains abnormality signals at measurement points based on detected electrical signals from the sensor group 1a.
Displays the details of the abnormality on the CRT and outputs an alarm signal.

The audio alarm output device 3 receives the alarm signal from the data logger 6a via the alarm signal line 7, combines the audio data registered in the device 3, and outputs the alarm signal.
A voice message is created and outputted to a voice output distribution circuit 8 provided in the engine control console 6 via a voice signal line 9.

The installation location of the speaker 4 that outputs the audio warning is
Similar to the buzzer (not shown), the engine control console 6 in the central control room, the wheelhouse control console 10 in the wheelhouse, and the extension alarm panel 11 in each room and all public rooms equipped with an engine extension alarm panel. . An audio signal from the audio warning output device 3 is guided to each speaker 4 installed at these installation locations via the audio output distribution circuit 8. The sound output distribution circuit 8 is activated by the engineer selection switch 12, and the engineer is selected during automatic operation in the same way as in the case of the buzzer alarm. In other words, an alarm is output in rooms other than the central control room only during automatic operation (unmanned operation), and selection switch 1
An audio warning will be issued to the living room and front public room selected in step 2.

Engineer selection switch 12 and voice distribution circuit 8
constitutes the means for selecting engineering staff.

The engine control console 6 also has the above-mentioned changeover switch 5.
In addition, a buzzer stop switch 13 and a flicker stop switch 14 are provided.

The changeover switch 5 selects whether to use an audio alarm or a buzzer alarm. If the audio alarm output device 3 is abnormal, the abnormality is detected by the data logger or monitor 6a via the abnormality detection line 15, and an automatic buzzer alarm is output. The buzzer stop switch 13 is a push button switch that has an added function of stopping the audio alarm, and stops the audio alarm with the same operation as stopping the buzzer alarm.

Note that the audio alarm in the living room is stopped by a push button switch (not shown) for stopping the buzzer on the extended alarm panel 11, similar to the buzzer alarm.

The fritsker stop switch 14 is connected to the data logger 6.
If the same alarm that continues to flicker on the CRT in a is input again, this is a push button switch that cancels the audio alarm and prevents it from occurring.Similar to the buzzer alarm, it stops the buzzer,
This switch is provided for pressing the main switch 14 after confirming the alarm point.

Now, in the above-mentioned configuration, when the voice alarm is selected with the changeover switch 5 installed in the engine control console 6, an abnormal signal from the measurement point sensor group 1a is obtained from the data logger 6a in the engine section, and the content of the alarm is transmitted to the speaker. Output from 4 by voice.

Therefore, since the content of the abnormality can be immediately recognized by the ear, there is no need to visually confirm which abnormality has occurred after hearing the alarm, as is the case with buzzer alarms. In addition, the sound output from the speaker 4 is transmitted to the room where the engineer is present and all public rooms by the engineer selection means.
Even during unmanned operation at night, etc., a warning is transmitted to the necessary engine engineers without interfering with other engine engineers, and furthermore, the work of confirming the contents of the alarm does not become complicated.

Furthermore, when the buzzer alarm is selected with the changeover switch 5, the buzzer outputs an alarm with a buzzer sound.

In this way, the changeover switch 5 can easily select whether to use an audio warning or a buzzer warning.

If an abnormality occurs in the audio alarm output device 3 while using the audio alarm, it will automatically switch to the buzzer alarm, and the data logger 6a will notify the audio system abnormality by displaying the buzzer alarm and the CRT of the data logger 6a as "Voice alarm system abnormality". ”.

On the other hand, the audio alarm output device 3 is connected to the data logger or monitor 6a via the alarm signal line 7 and the abnormal signal line 15, and to the audio output distribution circuit 8 via the audio signal line 9. In order to use the buzzer stop switch 13 and the flicker stop switch 14 in the audio warning system, the audio warning output device 3 is connected to the system. Moreover,
The selection switch 12 of the buzzer alarm system and the push button switch on the extension alarm panel 11 are also used for the audio alarm system, and a speaker for extension alarm is built into the extension alarm panel 11 so that the audio signal is used for the extension alarm as well. You can make maximum use of the facilities.

[Effects of the invention] In summary, according to the invention, by incorporating the audio warning output device into a part of the ship's warning system and systemizing it, and replacing the buzzer warning with an audio warning, the complicated work of recognizing abnormal points can be reduced. This allows for higher efficiency in the work of onboard engineers.
