[0042] Embodiment 1

[0043] Figure 1 The following is a schematic structural diagram of a methanol remote control security system for a marine engine provided in Embodiment 1 of the present invention. As Figure 1 shown, the methanol remote control security system for a marine engine includes: a remote control security monitoring controller 110, a remote control security monitoring touch screen 120, a methanol co-firing injection controller 130, a methanol co-firing injection touch screen 140, and a methanol supply station 150.

[0044] The remote control security monitoring controller 110 is used to process various types of information sent by the remote control security monitoring touch screen 120, the methanol co-firing injection controller 130, the methanol co-firing injection touch screen 140, and the methanol supply station 150, generate a target control instruction according to the information processing result, and send the target control instruction to the remote control security monitoring touch screen 120, the methanol co-firing injection controller 130, the methanol co-firing injection touch screen 140, or the methanol supply station 150.

[0045] The remote control security monitoring touch screen 120 is used to obtain the marine engine control instruction input by the technician, send the marine engine control instruction to the remote control security monitoring controller 110 for processing, and display the marine engine fault alarm information according to the alarm signal sent by the remote control security monitoring controller 110.

[0046] The methanol co-firing injection controller 130 is used to control the methanol co-firing injection of the injector on the marine engine.

[0047] The methanol co-firing injection touch screen 140 is used to obtain the methanol co-firing control parameters input by the technician and send them to the methanol co-firing injection controller 130 to control the injector on the marine engine.

[0048] The methanol supply station 150 is used to monitor in real time the methanol leakage signal inside the marine engine, and perform corresponding methanol supply control operations according to the methanol supply control signal sent by the remote security monitoring controller 110.

[0049] The inventor considered that during the process of methanol co-combustion in a marine engine, various factors that affect methanol injection and the operation safety of the marine engine may occur, such as methanol leakage and methanol supply pipeline failures. Therefore, a remote security system for a marine engine was proposed to ensure the operation safety of the marine engine and methanol supply equipment.

[0050] It can be understood that the remote security monitoring controller 110 and the remote security monitoring touch screen 120 can be regarded as the central processor and touch screen of the same device. The remote security monitoring controller 110 performs tasks related to calculation and control, and the remote security monitoring touch screen 120 performs tasks such as display and specific data transmission. Similarly, the methanol co-combustion injection controller 130 and the methanol co-combustion injection touch screen 140 can also be regarded as the central processor and touch screen of the same device. The methanol co-combustion injection controller 130 performs tasks related to calculation and control, and the methanol co-combustion injection touch screen 140 performs tasks such as display and specific data transmission.

[0051] During the process of methanol co-combustion, fuel is injected by the alcohol injector configured on the marine engine. After methanol combustion, kinetic energy can be provided to the marine engine. The methanol supply station 150 can supply methanol fuel to the alcohol injector on the marine engine. The relevant control parameters of the alcohol injector can be directly sent by the methanol co-combustion injection controller 130. The remote security monitoring controller 110 can mainly control the working state of the marine engine, and the remote security monitoring controller 110 can also generate some control instructions and send them to other structures in the methanol remote security system of the marine engine.

[0052] Furthermore, the remote security monitoring controller 110 can be connected to the marine engine to achieve relevant control of the marine engine; the methanol co-combustion injection controller 130 and the methanol supply station 150 can be connected to the alcohol injector to respectively achieve control of the alcohol injector and methanol supply to the alcohol injector.

[0053] Optionally, the remote security monitoring controller 110 can be respectively connected to a remote security monitoring touch screen 120, a methanol co-firing injection controller 130, a methanol co-firing injection touch screen 140, and a methanol supply station 150. Data interaction can be carried out between the methanol supply station 150 and the remote security monitoring controller 110 through the Modbus bus protocol; data interaction can be carried out between the remote security monitoring touch screen 120 and the remote security monitoring controller 110 through the PROFINET communication system. Since the information sent from the methanol co-firing injection controller 130 to the remote security monitoring controller 110 needs to go through variable transfer processing, the methanol co-firing injection controller 130 can first send the data to the methanol co-firing injection touch screen 140 for internal variable transfer, and then the methanol co-firing injection touch screen 140 sends it to the remote security monitoring touch screen 120, and then the remote security monitoring touch screen 120 transfers the variables and sends them to the remote security monitoring controller 110. Data interaction can be carried out between the methanol co-firing injection controller 130 and the methanol co-firing injection touch screen 140 through the CAN bus protocol, data interaction can be carried out between the methanol co-firing injection touch screen 140 and the remote security monitoring touch screen 120 through the ISO on TCP protocol, and data interaction between the remote security monitoring touch screen 120 and the remote security monitoring controller 110 can adopt a wired communication method. However, the present invention does not limit the communication method between any two devices, as long as the specified communication requirements can be met.

[0057] Optionally, the marine engine control commands input by the technician in the remote control security monitoring touch screen 120 may include boundary controls such as water supply, fuel supply, and lubricating oil for the engine operation; the marine engine fault alarm information displayed on the remote control security monitoring touch screen 120 may include methanol leakage alarm information and engine fault alarm information.

[0059] Furthermore, when the methanol co-firing injection controller 130 detects that the methanol injection amount and methanol injection angle need to be corrected, it can control the methanol injector to be corrected according to the calculated correction value, so as to improve the methanol use efficiency and reduce the methanol leakage risk.

[0060] Optionally, the methanol co-firing control parameters input by the technician in the methanol co-firing touch screen 140 may include methanol injection amount, methanol injection pulse width, methanol injection timing, and scavenging pressure.

[0062] Optionally, when the methanol supply station 150 and the remote security monitoring controller 110 are in a signal disconnection state, the methanol supply station 150 can still continue to operate, and the default pressure value preset in the control system of the methanol supply station 150 can be used as the current methanol supply pressure value.

[0063] During the actual methanol supply process, after pressure and temperature control, the methanol supply station 150 can transport the atmospheric-pressure methanol in the liquid storage tank to the main methanol pipeline of the host, and then send it to the methanol injector; the methanol co-firing injection controller 130 generates a drive enable signal according to the calculated control signal or the control command input by the technician on the remote security monitoring touch screen 120, and the drive control module provides a drive current according to the drive enable signal, so as to drive the methanol injector to perform the injection action.

[0067] Specifically, when the remote security monitoring controller 110 is ready for control, the sound and light prompting device 161 in the methanol remote security control box 160 that matches this state can perform sound and light prompts for its ready state; when the methanol co-firing injection controller 130 is ready for control, the sound and light prompting device 161 in the methanol remote security control box 160 that matches this state can perform sound and light prompts for its ready state; when the methanol supply station 150 is ready for supply, the sound and light prompting device 161 in the methanol remote security control box 160 that matches this state can perform sound and light prompts for its ready state. The methanol remote security control box 160 can also perform corresponding prompts for the operation state of the methanol injector on the marine engine. After the methanol injector starts methanol injection, the sound and light prompting device 161 in the methanol remote security control box 160 that matches this state can prompt that the methanol injector is currently in the methanol injection operation state.

[0068] Optionally, the first engine pipeline may refer to a methanol supply pipeline on a marine engine that can be monitored for its status by the methanol remote security control box 160. When the methanol remote security control box 160 detects methanol leakage in the first engine pipeline, the audible and visual alarm device 161 in the methanol remote security control box 160 that matches the methanol leakage status can indicate that there is methanol leakage in the first engine pipeline.
