[0028] Figure 1 This is a block diagram of the entire structure of a marine monitoring workstation provided by the present invention. Figure 2 This is a principle block diagram of the core module in a marine monitoring workstation provided by the present invention. Figure 1 , 2 As shown, a marine monitoring workstation comprises: a core module, a carrier board and a power module fixedly mounted and electrically connected inside a housing;

[0029] Among them, the core module is fixedly arranged on the carrier board, and the core module includes a core board and a Loongson 3A5000 processor, a Loongson 7A1000 bridge chip, a DDR3 memory and an SPI FLASH firmware fixedly arranged on the first surface of the core board. The Loongson 3A5000 processor is connected to the Loongson 7A1000 bridge chip through a Hyper Transport bus, and the Loongson 7A1000 bridge chip is connected to the DDR3 memory through a data bus and connected to the SPI FLASH firmware through an SPI bus;

[0030] The carrier board is connected via COM The Type 6 bus system is connected to the core module and is used to carry out electrical connections between various components of the core module and provide external interfaces; the power module is electrically connected to the carrier board and adopts an isolation filtering design to supply power to the carrier board and the core module.

[0031] In the workstation provided in this embodiment, the CPU adopts the Loongson 3A5000 quad-core processor with a main frequency of 1.8 to 2.3 GHz and is equipped with the Loongson independent bridge chip 7A1000; the bridge chip is equipped with domestically produced onboard memory particles, domestically produced Loongson independent BIOS, and the Kylin desktop operating system is installed, realizing a domestic product with 100% independently controllable electronic components and key software and hardware; the use of independently developed chips and operating systems reduces dependence on foreign supply chains, ensuring the stable supply and flexible customization of marine monitoring workstations.

[0032] Specifically, the workstation also includes a heat dissipation device, which includes a heat spreader, copper bosses, thermal grease and a cooling tube. The heat spreader covers the first side of the core board, and copper bosses are provided at positions corresponding to the Loongson 3A5000 processor and the Loongson 7A1000 bridge chip. Thermal grease is provided between the copper bosses and the Loongson 3A5000 processor and the Loongson 7A1000 bridge chip to make them fit tightly. The cooling tube is arranged on the side of the heat spreader facing away from the core board and is in contact with the outer shell.

[0033] In some embodiments, Figure 5 The figure shows the internal side view of the workstation. The heat source when the workstation is running mainly comes from the CPU, bridge chip and other chips. The heat spreader is equipped with copper bosses in the main heat dissipation area so that it can fit closely with the heat source of the motherboard. The protruding copper block on the heat spreader is close to the CPU, bridge chip and other heat-generating components of the motherboard, and thermal grease is provided between them, which can transfer the heat generated during the operation of the motherboard to the heat spreader in time; the other side of the heat spreader is provided with a cooling pipe, which is embedded in the inner side of the heat spreader and the outer shell respectively, and the heat generated during the operation of the machine is evenly transferred to the outer shell of the workstation through the cooling pipe. Because the multiple tooth-like structures of the heat dissipation fins on the outer shell increase the heat dissipation area, it makes it easier for heat to dissipate into the air, so the heat dissipation efficiency can be effectively improved. It is an efficient and reliable heat dissipation method.

[0034] Specifically, the power supply module is an isolated filtering power supply, including a filter, a DC-DC isolated power supply module and a filter capacitor. The filter output end is electrically connected to the input end of the DC-DC isolated power supply module, and the filter capacitor is connected in series with the input and output ends of the DC-DC isolated power supply module.

[0035] In some embodiments, the input power supply of the workstation is isolated and filtered, the power module is mainly composed of a filter, a DC-DC isolation power module and a filter capacitor, the output end of the filter is electrically connected to the input end of the DC-DC isolation power module, and the filter capacitor is connected in series with the input and output ends of the DC-DC isolation power module. Figure 4As shown in the figure, the working principle of the isolated filter power supply is as follows: the input voltage first passes through the EMI filter to suppress electromagnetic interference, and then enters the power conversion module for voltage conversion and preliminary electrical isolation; the converted voltage passes through the rectifier filter circuit to make it stable and reduce ripple and noise; then, the isolated sampling module samples the output current or voltage, and transmits the collected information to the PWM control module in isolation. The PWM control module adjusts according to the feedback information to ensure the stability and accuracy of the output; after PWM control, the power supply passes through the output circuit again to provide a stable isolated voltage output. The system power supply is DC12V±1V and DC5V, of which the mainboard is DC12V±1V, and the buttons and peripherals are powered by DC5V. After the above isolation and filtering design of the input power supply, the stability of the power supply and electromagnetic compatibility requirements are guaranteed.

[0036] Specifically, the external interfaces include 2 miniPCIe interfaces, 6 USB2.0 interfaces, 3 SATA2.0 interfaces, 1 HDA interface, 1 HDMI interface, 2 GMAC interfaces, 4 TTL serial ports, 2 RS232 serial ports and 8 GPIO interfaces.

[0037] Specifically, the 8-way GPIO interface includes 4-way GPI interfaces and 4-way GPO interfaces.

[0038] Specifically, the core module is connected to the carrier board using two groups of 220-pin board-to-board COM-E connectors.

[0039] In some embodiments, Figure 3As shown, the external interfaces connected to the carrier board include 2 miniPCIe interfaces, 6 USB2.0 interfaces, 3 SATA2.0 interfaces, 1 HDA interface, 1 HDMI interface, 2 GMAC interfaces, 4 TTL serial ports, 2 RS232 serial ports and 8 GPIO interfaces, of which the 8 GPIO interfaces include 4 GPI interfaces and 4 GPO interfaces. The carrier board is a self-developed product based on 100% self-controllable electronic components. It is the carrier of the core module. The main interfaces of the core board can be brought out and protected by electrical appliances through the carrier board. In addition, according to actual use needs, functions can be quickly deleted and interfaces customized, reducing system design risks and shortening system development time. In this embodiment, the carrier board and the core module are connected by two sets of 220-pin board-to-board COM-E connectors. The model of the core module end is: NGT A21-1220-0601-01C / 158CQSL-110-01-LDA / TE 3-6318490-6; the model of the carrier board end is: NGT A21-2220-0601-01C / 158CQTL-110-01-LDA(5mm) / TE 1827253_C1(5mm) / TE 3-6318491-6(8mm).

[0040] Specifically, the core module runs the Kylin desktop operating system.

[0041] Specifically, the Loongson 3A5000 processor has a built-in security module to ensure that all operations are performed in a protected environment, encryption and decryption algorithms to protect the security of data transmission and storage, and a trusted module to ensure the integrity of software and data.

[0042] In some embodiments, the Kylin desktop operating system is used as the operating system of the workstation. First of all, the Kylin desktop operating system is a domestically produced system with diverse functions, including efficient resource management, strong security performance and intelligent experience. The Kylin system supports multi-window operation and can run multiple applications at the same time, which improves the efficiency of multi-tasking; it also has an intelligent recognition function, which can make personalized recommendations and optimizations based on the user's usage habits. Secondly, the Kylin desktop operating system is an operating system with an inherent security system. It has innovatively developed active defense technology for foreign code and data protection technology, self-developed KYSEC security mechanism, and adopts an internal and external integrated security system. It can provide centralized security management and control, realize multi-dimensional security protection from the kernel to the application, and can effectively resist Trojan viruses, malicious code and external attacks. The Loongson 3A5000 processor has built-in security modules, encryption and decryption algorithms, and trusted modules. The security module ensures that all operations are carried out in a protected environment, and prevents unauthorized access through hardware isolation to protect the system from potential malicious attacks; the encryption and decryption algorithms are used to protect the security of data transmission and storage, and prevent sensitive information from being stolen or tampered with; the trusted module verifies key codes and firmware during system startup to ensure that the system has not been tampered with and runs reliably, and can also manage keys, perform digital signatures and other operations to ensure the integrity of software and data. The core module of the Loongson LS3A5000 processor and the Galaxy Kirin desktop operating system are equipped with a 100% autonomous and controllable marine monitoring workstation composed of a metal shell designed and produced by the company, realizing a 100% autonomous and controllable product.

[0043] Specifically, the outer side of the shell of the workstation is provided with heat dissipation fins.

[0044] Specifically, the shell is made of aluminum alloy.

[0045] In some embodiments, Figure 5 , 6 As shown, the present invention provides a heat dissipation fin design for the shell structure of the workstation. The fin is a thin sheet made of aluminum alloy, and its shape is like a comb with many parallel tooth structures. The fin is cast integrally with the casing and placed outside the casing. When the heat source generates heat, the casing and the heat dissipation device work together to conduct the heat to the surface of the fin, and the shape and arrangement of the fins are used to increase the heat dissipation area and improve the heat dissipation efficiency, and then the heat is transferred to the surrounding air by natural convection or forced convection.

[0046] The mechanical structure of the workstation adopts a fish fin-like appearance, and is fully covered and evenly distributed above and on the sides of the entire reinforced shell. The fish fin heat sink aluminum sheet is constructed on the entire workstation, and the heat generated by the operation of the internal accessories of the workstation is all discharged through the aluminum alloy sheet on the surface. To achieve the above functions, the following conditions are indispensable: (1) The main chassis is made of metal casting, which is not only strong and anti-magnetic, but also has effective heat dissipation capabilities; (2) The appearance adopts an aluminum alloy fin shape to expand the heat dissipation area of ​​the radiator, because aluminum has good heat transfer performance and strong corrosion resistance; (3) The CPU contact surface uses aluminum + copper tube or all-copper material to quickly transfer the CPU heat to the aluminum fin, because copper has excellent thermal conductivity and can quickly transfer heat to the heat sink or heat pipe, thereby improving the heat dissipation efficiency of the entire heat dissipation system. In addition, copper has very high corrosion resistance and can resist erosion and oxidation by most chemicals. Therefore, the copper radiator can be used in harsh environments and can maintain good heat dissipation performance for a long time; (4) Add thermal conductive silicone grease to the CPU contact surface of the workstation to improve the heat conduction efficiency of the CPU. With the support of the heat dissipation device, it can work without a fan and in a wide temperature range. It can operate normally 24 hours a day, 7 days a week at a temperature of -20℃ to +60℃. Its use will not affect the computing speed and will not cause any lag or freeze.

[0047] It should be noted that the above-described specific implementations can enable those skilled in the art to more fully understand the invention, but do not limit the invention in any way. Therefore, although this specification has described the invention in detail with reference to the drawings and embodiments, those skilled in the art should understand that the invention can still be modified or replaced by equivalents. In short, all technical solutions and improvements that do not deviate from the spirit and scope of the invention should be included in the protection scope of the patent for the invention.
