Description

Technical Field

[0001] This invention relates to the field of marine remote monitoring, specifically a remote monitoring device and data transmission method for a marine separator electrical control box. Background Technology

[0002] The marine separator electrical control box is a core electrical device on ships specifically designed to control the operation of the separator. It integrates control, monitoring, protection, and communication functions to ensure the separator operates stably, efficiently, and safely in the complex environment of a ship.

[0003] To improve operational efficiency, marine separator electrical control boxes are often equipped with remote monitoring devices to achieve real-time monitoring and remote management of equipment status. These devices transmit parameters such as temperature, pressure, and rotational speed collected by the control box to the ship's monitoring system or a shore-based platform via industrial Ethernet, 4G / 5G, or other communication methods. Technicians can remotely view the equipment's operating status, receive fault alarms (such as motor overload or abnormal separation performance), and quickly respond to problems through remote parameter adjustments and fault resets, shortening repair time and reducing operational costs.

[0004] Current remote monitoring devices are located in near-shore areas. Due to the high salt spray and high humidity of the marine environment, these devices are easily corroded. Therefore, the outer shell is sealed. However, during the use of remote monitoring devices, it is necessary to ensure proper cooling. The sealed outer shell hinders the convection and exchange of internal heat with the outside air, causing heat to accumulate inside the device. The CPU components inside the remote monitoring device operate less efficiently at high temperatures, which may lead to data acquisition errors or transmission delays. Summary of the Invention

[0019] It is readily understood that, based on the technical solution of this invention, those skilled in the art can propose various interchangeable structural methods and implementations without altering the essential spirit of the invention. Therefore, the following detailed embodiments and accompanying drawings are merely illustrative examples of the technical solution of this invention and should not be considered as the entirety of the invention or as limitations or restrictions on the technical solution of this invention.

[0020] An embodiment of the present invention is illustrated in conjunction with the accompanying drawings.

[0021] Example 1: Please see Figures 1-8 This is the first embodiment of the present invention. This embodiment provides a remote monitoring device for the electrical control box of a marine separator, including an outer shell assembly 1; an inner shell assembly 2 disposed inside the outer shell assembly 1; an independent air duct assembly 3 for ventilation; a heat dissipation assembly 7 for heat dissipation; and a filter assembly 8 for filtration. Housing assembly 1 includes: a stainless steel housing 101; The inner shell assembly 2 includes: an aluminum alloy inner shell 201 fixed inside the stainless steel outer shell 101; and a heat dissipation chamber 202 fixed to the rear end of the aluminum alloy inner shell 201. The air duct assembly 3 includes: an air inlet pipe 302 fixed to one side of the heat dissipation chamber 202; an exhaust pipe 304 fixed below the air inlet pipe 302; and a filter assembly 8 disposed at the air inlet end of the air inlet pipe 302. The filter assembly 8 includes: a filter chamber 801 threaded onto one end of the air intake pipe 302; a stainless steel filter screen 802 fixed inside the filter chamber 801; a HEPA filter element layer 803 disposed on one side of the stainless steel filter screen 802; and an activated carbon filter layer 804 disposed on one side of the HEPA filter element layer 803. The stainless steel filter screen 802 primarily serves as a preliminary filter, intercepting larger particulate impurities and droplets. For salt spray, it can filter out larger salt spray particles and potentially larger droplets, reducing the burden on subsequent filter layers and preparing for finer filtration.

[0022] HEPA filter layer 803: HEPA (High Efficiency Particulate Air) filters have high filtration efficiency and can effectively filter particles larger than 0.3 microns. Many fine salt particles in salt spray can be intercepted by HEPA filters, further improving the filtration effect and removing most of the salt spray particles.

[0023] Activated carbon filter layer 804: Activated carbon has a strong adsorption capacity and can adsorb odors, harmful gases, and some fine particles in the gas. For salt spray filtration, activated carbon can adsorb volatile organic compounds (VOCs) and some fine salt particles that may be present in the salt spray, further purifying the incoming gas; The filter chamber 801 is threadedly connected to the air intake pipe 302, and the filter chamber 801 is also threadedly connected to the air intake valve 301. The filter chamber 801 can be replaced periodically as needed.

[0024] The heat dissipation component 7 includes a heat dissipation fan 704 installed inside the heat dissipation chamber 202, and the heat dissipation fan 704 may preferably be a centrifugal fan.

[0025] Furthermore, the inner shell assembly 2 also includes: a display screen 4 embedded inside the aluminum alloy inner shell 201; a CPU processor 5 disposed on one side of the display screen 4; and a communication module 6 installed on one side of the CPU processor 5.

[0026] It should be noted that the display screen 4 is used to display the data collected by the electrical control box of the marine separator, the CPU processor 5 is used to process the data obtained by the electrical control box of the marine separator, and the communication module 6 is used to realize data communication with the back-end server.

[0027] Furthermore, the housing assembly 1 also includes: a housing base 102 fixed below the stainless steel housing 101, the surfaces of the stainless steel housing 101 and the aluminum alloy inner housing 201 are both provided with openings that are compatible with the display screen 4, the gap between the display screen 4 and the stainless steel housing 101 is filled with silicone strips, and the stainless steel housing 101 is a fully sealed structure.

[0028] It should be noted that the remote monitoring device consists of a stainless steel outer shell 101 and an aluminum alloy inner shell 201, forming a double shell to prevent salty gases from the near-shore area from entering the interior of the aluminum alloy inner shell 201 and to protect the electrical components inside the aluminum alloy inner shell 201.

[0029] Furthermore, the surface of the aluminum alloy inner shell 201 is coated with a nano anti-corrosion coating, and the aluminum alloy inner shell 201 and the heat dissipation chamber 202 are an integrated structure.

[0030] It should be noted that the heat dissipation component 7 is installed inside the heat dissipation chamber 202 and is used to cool the heat dissipation chamber 202.

[0031] Furthermore, the air duct assembly 3 also includes: a one-way valve 303 fixed to the end of the exhaust pipe 304; and an intake valve 301 disposed on one side of the filter chamber 801.

[0032] It should be noted that the air duct assembly 3 constitutes an independent air duct, which does not pass through other electronic components, thus achieving isolation from electronic components and further preventing the salt-containing gases in the near-shore area from coming into contact with the electronic components.

[0033] Furthermore, the intake valve 301 is interconnected with the heat dissipation chamber 202 through the filter chamber 801 and the intake pipe 302, and the heat dissipation chamber 202 is interconnected with the one-way valve 303 through the exhaust pipe 304.

[0034] It should be noted that during heat dissipation, the intake valve 301 and the one-way valve 303 are opened. After the external gas is filtered by the filter chamber 801, it enters the heat dissipation chamber 202 through the intake pipe 302. Then, the exhaust gas in the heat dissipation chamber 202 is discharged to the outside through the one-way valve 303 on the exhaust pipe 304. This can achieve heat dissipation for the remote monitoring device while preventing salt spray.

[0035] In this embodiment, a double shell is formed by a stainless steel outer shell 101 and an aluminum alloy inner shell 201 to improve the sealing effect of the remote monitoring device. Furthermore, an independent air duct assembly 3 is set inside the stainless steel outer shell 101 and the aluminum alloy inner shell 201 to isolate them from electronic components and further prevent salty gases in the near-shore area from coming into contact with electronic components. With the heat dissipation component 7 in place, when the cooling fan 704 is working, the intake valve 301 and the one-way valve 303 are opened. After the external air is filtered by the filter chamber 801, it enters the heat dissipation chamber 202 through the intake pipe 302. Then the exhaust gas in the heat dissipation chamber 202 is discharged to the outside through the one-way valve 303 on the exhaust pipe 304. This can achieve heat dissipation for the remote monitoring device while preventing salt spray.

[0036] Example 2: Please see Figures 4-7 This is the second embodiment of the present invention, which provides a remote monitoring device for the electrical control box of a marine separator.

[0037] Furthermore, the heat dissipation assembly 7 also includes: a heat sink 701 disposed on one side of the CPU processor 5; mounting ears 707 fixed around the heat sink 701; heat dissipation fins 702 disposed on the side of the heat sink 701 away from the CPU processor 5; and a heat pipe 703 penetrating inside the heat dissipation fins 702.

[0038] It should be noted that the surface of the heat dissipation fins 702 is anodized, and the spacing between the heat dissipation fins 702 is ≥3mm, which can avoid salt accumulation. The working heat dissipation fan 704 works in conjunction with the heat dissipation fins 702 and the heat pipe 703 to achieve composite heat dissipation and improve the heat dissipation effect on the remote monitoring device.

[0039] Furthermore, the heat dissipation assembly 7 also includes: a water collection chamber 705 disposed below the heat dissipation fins 702; and a drain pipe 706 fixed to the bottom of the water collection chamber 705, the drain pipe 706 having a U-shaped bend structure.

[0040] It should be noted that the U-shaped bend of the drain pipe 706 can retain some water, which can block the drain pipe 706 and prevent external gas from entering. Meanwhile, the condensate on the surface of the heat pipe 703 can flow down along the heat dissipation fins 702, be discharged into the water collection chamber 705, and be discharged outward through the drain pipe 706.

[0041] Furthermore, the heat sink 702 has an inclination angle of 15°, the mounting plate 707 on the heat sink 701 is installed on the side of the CPU processor 5 by screws, and thermal grease is sandwiched between the CPU processor 5 and the heat sink 701.

[0042] It should be noted that the heat sink 701 is embedded in the side of the heat sink 202 and sealed with silicone to the heat sink 202, so that the heat sink 202 is in a sealed state. The heat on the CPU processor 5 can be transferred to the heat sink 701 through thermal grease. One end of the heat pipe 703 is connected to the heat sink 701, and the heat on the heat sink 701 can be transferred to the heat sink fins 702 through the heat pipe 703. The cooling fan 704 can make the airflow pass quickly through the heat sink fins 702 to cool the heat sink fins 702.

[0043] In this embodiment, the heat dissipation component 7 and the heat dissipation fan 704 enable airflow to pass quickly through the heat dissipation fins 702 when they are working. They work together with the heat dissipation fins 702 and the heat pipe 703 to achieve composite heat dissipation and improve the heat dissipation effect on the remote monitoring device.

[0044] Example 3: Please see Figure 8 This is the third embodiment of the present invention, which provides a data transmission method, including the following steps: S1. Data Acquisition: The PLC controller in the electrical control box of the separator reads the sensor data in the electrical control box of the separator and outputs it. S2. Protocol Conversion: Convert the original protocol into a standard industrial protocol through an industrial communication gateway; S3. Data transmission: After passing through the industrial communication gateway, the data is transmitted to the industrial Ethernet switch and then to the shipboard core switch. S4. Data Processing: The shipborne core switch filters abnormal data through an industrial computer, and then transmits the data to the backend server via satellite and cellular networks. S5. Data Access: The communication module 6 connects to the backend server, and after being processed by the CPU processor 5, the display screen 4 can display the data.

[0045] It should be noted that the electrical control box of the separator is equipped with a programmable logic controller (PLC controller) for reading sensor signals, and the local communication equipment includes an industrial communication gateway and an industrial Ethernet switch.

[0046] The industrial communication gateway reads data from the PLC controller and transmits the proprietary protocol or industrial fieldbus protocol used by the device.

[0047] In this embodiment, a dual-link backup is formed between the industrial Ethernet switch and the shipborne core switch. Automatic switching occurs when a single link fails, and the transmission interruption time is less than 50ms, meeting the continuous monitoring requirements during ship navigation. Furthermore, the industrial computer performs real-time filtering of abnormal data (such as sudden changes in sensor readings and communication packet loss). Threshold judgments (such as triggering an alarm when the temperature exceeds 120°C) and sliding window algorithms (such as considering data fluctuations exceeding 10% within 5 seconds as abnormal) reduce the upload of invalid data and lower the load on the backend server.

[0048] Working Principle: The PLC controller in the separator's electrical control box reads sensor data from the box and outputs it. The original protocol is converted to a standard industrial protocol via an industrial communication gateway. The data is then transmitted to an industrial Ethernet switch and finally to the shipboard core switch. The shipboard core switch filters abnormal data using an industrial computer and then transmits it via satellite and cellular networks to the backend server. The communication module 6 connects to the backend server. After processing by the CPU processor 5, the data is displayed on the screen 4. While the CPU processor 5 is working, the cooling component 7 is simultaneously activated. When the cooling fan 704 is working, the intake valve 301 and the one-way valve 303 open. External air passes through the stainless steel filter 802, HEPA filter layer 803, and activated carbon filter layer 804 inside the filter chamber 801 before entering the cooling fan through the intake pipe 302. In the heat chamber 202, airflow rapidly passes through the heat dissipation fins 702, and the heat on the CPU processor 5 is transferred to the heat sink 701 via thermal grease. One end of the heat pipe 703 is connected to the heat sink 701, and the heat on the heat sink 701 is transferred to the heat dissipation fins 702 via the heat pipe 703, thereby cooling the CPU processor 5. If condensation occurs on the surface of the heat pipe 703 due to the temperature difference, the water droplets can be discharged outward through the drain pipe 706 at the bottom of the water collection chamber 705. The U-shaped bend of the drain pipe 706 can retain some water, blocking the drain pipe 706 and preventing external gas from entering. The high-temperature exhaust gas in the heat dissipation chamber 202 is discharged outward through the one-way valve 303 on the exhaust pipe 304, achieving heat dissipation and cooling of the remote monitoring device. The filter chamber 801 is threadedly connected to the air intake pipe 302 and also threadedly connected to the air intake valve 301. The filter chamber 801 can be replaced periodically as needed.

[0049] The technical scope of this invention is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this invention, and all such modifications and variations should fall within the protection scope of this invention.
