Embodiment FIG. 1 is a block diagram showing the electrical construction of an embodiment of the present invention. The main control unit 1 includes therein a signal forming circuit 2, amplifiers 3 and 4, a power supply unit 5, a bell sound generation circuit OSC1 including an oscillator, a rattle sound generation circuit OSC2 including an oscillator, and relays RY1 to RY5. However, the operation switches S20 to S24 described in the block of the main control unit 1 are arranged on the operation panel 6 described later. The signal forming circuit 2 includes a whistle signal forming circuit 2a, a bell signal forming circuit 2b, and a dora signal forming circuit 2c.

Operation switches S1 to S24 are arranged on the operation panel 6,
Among these operation switches, the operation switches S1 to S15 are used when issuing a whistle signal, the operation switch S16 is used when issuing a bell signal, and the operation switch S17 is used when issuing a gong signal. Operation switches S18, S19
Is used to generate both the bell signal and the gong signal. These signal modes will be described later.

The outputs of the operation switches S1 to S15 are individually input to the whistle signal forming circuit 2a, and corresponding to the operation switches S1 to S15 individually, a predetermined steam whistle signal waveform is derived to the line l1. The output of the operation switch S16 is the bell signal forming circuit 2
A bell signal waveform that is input to b and is predetermined corresponding to the operation switch S16 is derived to the line l2. Operation switch
The output of S17 is input to the gong signal forming circuit 2c, and a gong signal waveform predetermined corresponding to the operation switch S17 is derived to the line l3.

The outputs of the operation switches S18 and S19 are individually and commonly input to both the bell signal forming circuit 2b and the gong signal forming circuit 2c, and a predetermined bell signal waveform and a gong signal waveform, The lines l2 and l3 are respectively derived. As the operation switches S1 to S24, one-touch type push button switches are used.

The signal forming circuits 2a, 2b, 2c are each configured by a microcomputer, a timer, a pulse oscillator, etc.,
By pressing each operation switch, an accurate signal waveform is derived to the lines l1 to l3.

The whistles 7 and 8 and the signal lamp 9 are respectively connected to one terminals of the contacts ry1, ry2, and ry3 of the relays RY1, RY2, RY3, and are energized by the power from the power supply unit 5 via the above-mentioned contacts.

Speakers 10a and 10b that are the first sounding bodies; speakers 11a and 11b that are the second sounding bodies are connected in parallel, and the speakers 10a and 10b are connected.
Is connected to line l11 via junction box J1 and speaker 11
The a and 11b are connected to the line l12 via the junction box J2 and are energized by the outputs of the amplifiers 3 and 4, respectively.

These whistles 7,8, signal lights 9, and speakers 10a, 10b; 11a, 11b constitute the signal equipment of the ship. For example, as shown in FIG. 4, the first whistle 7 and the first speakers 10a, 10b are hulls. 21 on the bow 21a, the second whistle 8 and the signal light 9 on the central part 21b or the rear part 21c of the hull 21, and the second speakers 11a, 11b.
Is located at stern 21c.

The operation will be described with reference to FIG. 1 again. First, when transmitting a whistle signal, the whistle selection operation switch S21 is turned on, and either the selection operation switch S23 or the selection operation switch S24 is selected depending on whether the first whistle signal or the second whistle signal is generated. Either or both are turned on. For example, in the case of overtaking on the starboard side with the above-mentioned marine vessel maneuvering signal in Table 1, the first steam whistle 7 and the second steam whistle 8 are simultaneously sounded, so that all the operation switches S23, S24 and the steam whistle selection operation switch S21 are turned ON At the same time, the operation switch S8 is pressed, the relays RY1 and RY2 are driven by the signal output led to the line l1, and the contacts ry1 and ry2 of the relays RY1 and RY2 perform the opening / closing operation in response to the signal output. Therefore, both whistles 7 and 8 emit an overtaking signal. At this time, when the light emission signal is also transmitted at night or the like, the signal light selection operation switch S22 may be turned on. For the light emission signal, push button switch P1
Is connected to the line l6 via the line l7, so that when the signal mode is free, for example, a continuous light emission signal, the external operation switch P1 can be pressed.

Also, when transmitting a bell signal or an idol signal, for example, during the night of the table 4 above, turn on the operation switch S18.
If so, the bell signal is led to the line l2 and the gong signal is led to the line l3, and the bell sound generation circuit OSC1 and the gong sound generation circuit OSC2 are both activated and converted into a sound signal, and at the same time, the lines l2, l3 Relays RY4 and RY5 are driven by the signal output derived to
Since ry4 and ry5 perform the opening / closing operation in response to the signal output, the output of the bell sound generation circuit OSC1 is input to the amplifier 3 as an intermittent signal having a predetermined waveform, and the output of the gutter sound generation circuit OSC2 is determined. It is input to the amplifier 4 as a waveform intermittent signal. As a result, the first loudspeakers 10a and 10b at the bow emit a bell signal, and the second loudspeakers 11a and 11b at the stern emit a gutter sound signal. The amplifiers 3 and 4 have an output of 100 watts, for example, and the speakers 10a, 10b and 11a, 11b are all waterproof for ships.
A 50 watt output is used to ensure the sound pressure specified by law. The same applies to the first steam whistle 7 and the second steam whistle 8.

The power supply unit 5 can support different power supply voltages, for example,
Two power input terminals, AC100 / 110V and AC200 / 220V, are provided on the operation panel.
ON / OFF control is performed from S20 via line l16. Power supply 5
The output of is supplied to the operating power of the whistles 7 and 8, the amplifiers 3 and 4, and the signal forming circuit 2.

A battery (not shown) for compensating for a power failure is built in the printer 6 so that the date does not get out of order even during a power failure. When the date changes from time 23:59 to time 00:00, the date is automatically recorded in the printer 12. The operation switch S25 arranged in the vicinity of the printer 12 is pressed especially when it is desired to record the date when leaving the port. After the power switch S20 is turned on, when the operation switches S1 to S19 are turned on and a signal is issued, the mode of the signal is automatically recorded / printed on the printer 12 together with the transmission time.
