Abstract

PURPOSE:To realize quickly an energy saving state by setting an illuminating/ air-conditioning device to a non-operating state, in case of a state that no abnormality is generated in an engine room, and resetting it to a control of an operating switch, when an abnormality is generated in the engine room. CONSTITUTION:An unmanned operating signal S2 is sent to an AND circuit 10 from an engine room unmanned operation sensor 4 by an engine room unmanned operation. On the other hand, when a selecting switch 1 is selected to a generating position of a selecting switch, an operating signal S3 of an energy saving signal generating device of a high level is sent to the circuit 10. Also, when an energy saving cancelling signal S4 is generated in an abnormality sensor 12 in an engine room, the energy saving cancelling signal -S4 is sent to the circuit 10 through a NOT circuit 17, the signals S2, S3 and -S4 are calculated by the circuit 10, a control signal S1 becomes a low level, and an energy saving switch 19 becomes on. Accordingly, use of an illuminating/air-conditioning device 20 by an operating switch 18 can be executed. However, unless the signal S4 is generated, the switch 19 becomes off, and the device 20 bcomes a non- operating state by preceding the switch 18.

〔Example〕

Hereinafter, embodiments of the present invention will be explained with reference to the drawings.

Once selected as a
This means that the engine room is in manned operation, and the on-duty equipment (2nd engine + 3rd engine) is in operation.
If any one person (e.g. erw4th engineer) is selected, it means that the engine room will be unmanned. This idea is
This is common to all types of ships.

In the normal state return mechanism C, a signal (hereinafter referred to as the "energy saving cancel signal") becomes high level (on) when the occurrence of an abnormal state (warning state of various alarms) is detected from the engine room abnormality occurrence sensor 12. S4 is inverted by a NOT circuit (seven-cut circuit) 17, and this inverted signal is received at one input terminal of an AND circuit 10.

That is, the output signal S of the AND circuit 10 is the AND shown in the following equation.

S+=S2・Syu・S4... (1)
In the first equation, (S2 and S3) mean energy saving control signals, and each signal is turned on (rl
It takes only two values: J) or off (IQ J).

As shown in FIGS. 2 to 4, in each modification of the main part of the present invention, the engine room unmanned operation sensor 4. Operation switch 18. The illustration of the energy saving switch 19 and the lighting/air conditioner 20 is omitted.

In the modification shown in FIG. 2, the reference numeral 1 indicates a selection switch for selecting "generation" or "stop" of the energy saving signal, and 2 indicates the "stop" position of the selection switch 1. If selected, the labor-saving winter signal will be generated.
V device A does not operate.

Further, reference numeral 3 indicates the "generate" position of the selection switch 1, and when this position is selected, the energy-saving signal generator activation signal S is generated, the energy-saving signal generator is activated, and the condition is met. Once this is done, the AND circuit 10 outputs an energy-saving signal (), which is an E-level control signal S+).

It is constructed on the assumption that A14 City Chiiyotshiq 7 and -t ■ Sekitsuma right humanization signal S6 inverted 86 are equal, and the logical product of each is the same as the rlJ1 formula, '#1 The components of the logic circuit shown in FIG. 3 and those shown in FIG. 4 are different.

Since the energy saving device for the engine room of a ship as an embodiment of the present invention is configured as described above, the circuit configuration shown in FIG. Any one of the signal groups is generated (=when the on-duty shell is selected, it becomes unmanned). The engine room unmanned operation signal S2 from the engine room unmanned operation sensor 4 is sent to the [OR circuit 5→AND circuit 8].

On the other hand, when the selection switch 1 is selected to the generation position 3 of the selection switch, the energy saving signal generating device A is activated and an energy saving signal generating device activation signal S of a high level is sent to the AND circuit 8.

S t is calculated by the AND circuit 10 and an energy saving signal is output to the energy saving switch 19 . That is, the control signal S1 becomes high level, and the energy saving switch 19 is turned off (open).

As a result, even if the lighting/air conditioning system is activated by the operation switch 18, the lighting/air conditioning system r! 120 takes priority over operation switch 18 and becomes inactive.

Furthermore, when the selection switch 1 is selected at the selection switch stop position i2, even if all other conditions are met, the energy saving control signal S is not output, and the selection switch 1 is set at the selection switch generation position 3. When the selection switch is switched to the stop position 2 again in the state where it is selected and the energy saving control signal S is being output, the energy saving control signal S5 is immediately stopped being output.
