However, the present invention can be implemented in many different forms and is not limited to the embodiments described in this specification.

The term "and / or" as used in this specification includes any and all combinations of one or more of the relevant listed items.

[0019] Figure 1 This is a schematic diagram of the components of a remote control device for an oil engine according to the present invention. The device comprises a near-end optical terminal 101, a far-end optical terminal 102, a first relay 103, and a second relay 104. The near-end optical terminal 101 and the far-end optical terminal 102 are connected via optical fibers. The far-end optical terminal 102 is provided with a remote control interface 1021, electrically connected to a first knob 106 and a first button 107, respectively. The near-end optical terminal 101 is provided with a near-end control interface 1011, electrically connected to the input of the first relay 103 and the input of the second relay 104, respectively. The output of the first relay 103 and the output of the second relay 104 are each electrically connected to the control terminal of a controlled oil engine 105.

[0020] exist Figure 1In the embodiment, since the near-end optical terminal 101 and the far-end optical terminal 102 are connected by optical fiber, the distance between the two optical terminals can reach tens of kilometers. Therefore, the controlled oil engine 105 can be remotely started and stopped by operating the first knob 106 and the first button 107.

[0021] Further, such as Figure 2 As shown, the remote optical terminal 102 includes a first optocoupler circuit 1022, a second optocoupler circuit 1023 and an optical signal modulator 1024, wherein the first output end and the second output end of the remote control interface 1021 are electrically connected to the first optocoupler circuit 1022 respectively, the first output end is connected to the first knob, and the second output end is grounded; the third output end and the fourth output end of the remote control interface 1021 are electrically connected to the second optocoupler circuit 1023 respectively, the third output end is connected to the first button, and the fourth output end is grounded.

[0022] The first optocoupler circuit 1022 and the second optocoupler circuit 1023 have the same circuit composition, such as Figure 3 As shown, the first end 1 of the optical coupler is connected to the first resistor R1 and then to the DC power supply, the second end 2 is used to connect to the first knob or the first button, and the third end 3 and the fourth end 4 are used to connect to the optical signal modulator 1024. Figure 2 When the first knob or the first button is grounded, the first terminal 1 and the second terminal 2 of the optical coupler device are connected, and the internal light-emitting diode emits light, so that the third terminal 3 and the fourth terminal 4 are connected from the disconnected state, thereby controlling the optical signal modulator 1024 to generate an optical pulse signal, which is then modulated and transmitted through the optical fiber.

[0023] Further, such as Figure 4 As shown, the proximal optical terminal 101 includes a first photoelectric conversion circuit 1012, a second photoelectric conversion circuit 1013 and an optical signal demodulator 1014, wherein the first output end and the second output end of the proximal control interface 1011 are electrically connected to the first photoelectric conversion circuit 1012 respectively, the first output end is connected to the first power supply, and the second output end is grounded; the third output end and the fourth output end of the proximal control interface 1011 are electrically connected to the second photoelectric conversion circuit 1013 respectively, the third output end is connected to the second power supply, and the fourth output end is grounded.

[0024] The first photoelectric conversion circuit 1012 and the second photoelectric conversion circuit 1013 have the same circuit composition, such as Figure 5As shown, the positive electrode of the photodiode VD is grounded, the negative electrode is electrically connected to a third resistor R3, and then to the first power supply or the second power supply. The negative electrode of the photodiode VD is also electrically connected to the base of the transistor Q1. The collector of the transistor Q1 is electrically connected to a second resistor R2, and then to the first power supply or the second power supply. The emitter of the transistor Q1 is grounded, and a fourth resistor R4 is connected between the base and emitter of the transistor Q1. When the optical signal demodulator 1014 receives an optical pulse signal, it demodulates it and converts it into an optical signal that is irradiated onto the photodiode VD, causing the photodiode VD to switch from an off state to a on state. This controls the connection between the base and emitter of the transistor Q1 from an on state to an off state, thereby controlling the connection between the collector and emitter of the transistor Q1 from an on state to an off state, that is, controlling the connection or disconnection of the circuit between the first power supply or the second power supply and ground.

[0025] Further, combined Figure 1 The input terminals of the first relay 103 include a first input terminal 7 and a second input terminal 8, which correspond to the first power supply and the second output terminal of the local control interface 1011, respectively. The common terminal 5 of the first relay 103 is electrically connected to the positive terminal of the battery of the controlled oil engine. The output terminals of the first relay 103 include a first controlled terminal 3 and a second controlled terminal 1. The first controlled terminal 3 is used to electrically connect to the stop terminal (STOP) of the controlled oil engine, and the second controlled terminal 1 is used to electrically connect to the run terminal (ON) of the controlled oil engine. The control terminals of the controlled oil engine 105 include a stop terminal (STOP), a run terminal (ON), and a start terminal (START). These control terminals collectively correspond to the same ground terminal, which is electrically connected to the negative terminal of the battery.

[0026] The input terminals of the second relay 104 include a third input terminal 7 and a fourth input terminal 8, which are respectively connected to the second power supply and the fourth output terminal of the local control interface 1011. The common terminal 5 of the second relay 104 is also electrically connected to the positive terminal of the battery of the controlled oil generator. The output terminals of the second relay 104 include a third controlled terminal 3 and a fourth controlled terminal 1. The fourth controlled terminal 1 is used to electrically connect to the start terminal (START) of the controlled oil generator.

[0027] based on Figure 1 In the remote control device, when the first knob is turned, the first knob changes from a normally-off state to a normally-on state, and the corresponding first switch signal is transmitted through the far-end optical terminal and the near-end optical terminal, so that the first input terminal 7 and the second input terminal 8 of the first relay 1 are closed, the first power supply powers on the two input terminals of the first relay, the common terminal 5 and the first controlled terminal 3 of the first relay 103 are disconnected, and the common terminal 5 and the second controlled terminal 1 are closed, the stop terminal (STOP) of the controlled oil engine is disconnected, and the run terminal (ON) is closed.

[0028] Next, when the first button is pressed, the corresponding second switching signal is transmitted through the remote optical terminal and the local optical terminal, causing the third input terminal 7 and the fourth input terminal 8 of the second relay to close. The second power supply energizes the two input terminals of the second relay, and the common terminal 5 of the second relay 104 and the third controlled terminal 3 are disconnected. At the same time, the common terminal 5 of the second relay 104 and the fourth controlled terminal 1 are closed, and the start terminal (START) of the controlled oil generator is connected, and the oil generator starts. When the first button is released, the input terminal of the second relay is de-energized, the common terminal 5 of the second relay 104 and the fourth controlled terminal 1 are disconnected, and the common terminal 5 of the second relay 104 and the third controlled terminal 3 are closed. However, the controlled oil generator has already started, and its operation is not affected.

[0029] When the first knob is rotated, the first knob changes from the normally on state to the normally off state, and the corresponding third switch signal is transmitted through the remote optical terminal and the near-end optical terminal, so that the first input terminal 7 and the second input terminal 8 of the first relay 1 are disconnected, the first relay 1 is powered off, the common terminal 5 of the first relay 103 is disconnected from the second controlled terminal 1, the common terminal 5 and the first controlled terminal 3 are closed, the running terminal (ON) of the controlled oil engine is disconnected, the stop terminal (STOP) is closed, and the oil engine stops working.

[0030] As can be seen, this application discloses a remote control device for an oil engine, comprising a near-end optical terminal, a far-end optical terminal, a first relay, and a second relay. The near-end optical terminal and the far-end optical terminal are connected via optical fiber, and the far-end optical terminal is provided with a remote control interface, electrically connected to a first knob and a first button, respectively. The near-end optical terminal is provided with a near-end control interface, electrically connected to the input end of the first relay and the input end of the second relay, respectively. The output end of the first relay and the output end of the second relay are respectively used to electrically connect to the control end of the controlled oil engine.
