Description

Technical Field

[0001] This utility model relates to the field of information and communication technology, specifically to a housing structure for a multi-protocol information interaction device. Background Technology

[0002] As a vital maritime transportation tool, ships have evolved towards larger, more integrated, more complex, more automated, and more intelligent designs in recent years, driven by the booming global shipping industry. The information required by ships is also becoming increasingly complex. Ship information platforms are complex systems composed of several subsystems. The interactions between these subsystems and with external systems are intricate, with the vast majority of information exchange occurring via network transmission. When multiple systems on a ship information platform work collaboratively, they need to process and transmit large amounts of data. This data is diverse in type and format, involving communication between interfaces of multiple devices using different standards and protocols, such as traditional serial communication, 1553B bus networks, Ethernet, and fiber optic communication. With the increasing complexity of ship systems, the requirements for the reliability, real-time performance, and compatibility of information protocol conversion and transmission between different devices are also becoming increasingly stringent.

[0003] Furthermore, the limited space available for electrical equipment on ships necessitates the current design of dedicated information exchange devices for protocol conversion and transmission between different devices. While this ensures relatively stable information transmission between individual devices, the sheer number of devices requiring information exchange on a ship necessitates the deployment of numerous such devices, significantly impacting the ship's electrical equipment space. Therefore, integrated information exchange devices with multi-protocol information conversion capabilities are highly suitable for marine applications. Under current electronic information technology conditions, designing a multi-protocol information exchange device integrating multiple interface communication modes and protocol conversion capabilities is readily achievable. This can be accomplished using a multi-interface communication MCU (Microcontroller Unit) chip, programmed to handle data conversion between different interface communication modes and protocols. Combined with appropriate register circuits and interface circuitry, the electrical architecture of the multi-protocol information exchange device can then be designed.

[0004] However, a new problem arises: the dedicated information exchange equipment between the two devices, the multi-protocol information exchange equipment, not only needs to possess multi-interface communication modes and multi-protocol conversion capabilities between various devices, but also, because numerous different devices on the ship need to communicate through this multi-protocol information exchange equipment via information protocol conversion, this increases the data transmission volume and communication workload of the multi-protocol information exchange equipment, increasing the chance of the equipment operating under high load and the risk of high electrical heat. Furthermore, the multi-protocol information exchange equipment also needs to operate among many other different electrical devices, potentially facing random electromagnetic interference, which may also interfere with the stability of equipment operation. Therefore, how to reduce the operational risks and improve operational stability from aspects such as structural design is also a technical problem that needs to be solved in the overall enclosure structure design of the multi-protocol information exchange equipment. Utility Model Content

[0005] To address the aforementioned shortcomings of existing technologies, the present invention aims to provide a housing structure for a multi-protocol information interaction device, thereby reducing the operational risks of multi-protocol information interaction devices under complex working conditions on ships and helping to improve operational stability.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0007] A multi-protocol information interaction device housing structure is characterized by comprising a housing assembly with an opening on one side, and a housing cover installed on the opening side of the housing assembly. The inner circumferential side of the opening side of the housing assembly has a mounting frame that protrudes towards the inner cavity of the housing assembly. The side of the mounting frame facing the housing cover has a recessed groove. The housing assembly has mounting holes evenly distributed along the mounting frame. The housing cover has fixing holes at positions corresponding to the mounting holes. The housing assembly is fixed to the housing cover by screws after the mounting holes on the mounting frame are aligned with the fixing holes on the housing cover.

[0008] The enclosure assembly includes an integrally formed enclosure and a bottom plate. The bottom plate is installed at the bottom of the enclosure. The enclosure is formed by a front panel, a rear panel, and two side panels. The enclosure assembly has a main control circuit board inside. The main control circuit board has threaded holes for fixing to the bottom plate. The bottom plate has threaded blind holes at the positions corresponding to the threaded holes. The main control circuit board is fixed to the bottom plate by countersunk screws through the threaded holes and the threaded blind holes on the bottom plate.

[0009] The front panel of the enclosure has multiple holes for installing sockets.

[0010] The working principle of this utility model is as follows: The socket in this embodiment includes a power socket, a 1553B socket, an IO socket, and a serial port socket. The socket is connected to the main control circuit board through internal connecting wires. The enclosure structure receives DC24V power from the power supply equipment through the power socket. After power conversion by an external power chip and a DC / DC power module, the power supply needs of the enclosure structure are met. The main control circuit board controls the 1553B bus through the built-in 1553B IP core. The 1553B is a serial data bus standard used in the aerospace field, supporting multiple communication modes, including broadcast (BC), remote terminal (RT), and multi-function terminal (MT). By connecting a 1553B transceiver and an isolation transformer, the enclosure structure can achieve redundant communication of the 1553B bus. The controller supports BC / RT / MT modes and supports transformer coupling / direct coupling to the bus. The GPIO interface achieves electrical isolation through an optocoupler chip, which can achieve 24V electrical isolation and 10mA drive capability.

[0011] Thus, the multi-protocol information interaction device enclosure structure in this embodiment integrates power supply and multiple communication modes by equipping it with various sockets. The 1553B socket achieves highly reliable 1553B bus communication through the 1553B IP core and redundant design built into the main control circuit board, supporting multiple communication modes and coupling methods. This means that even if one communication path fails, the other path can still ensure communication continuity, improving system reliability. The GPIO interface achieves 24V electrical isolation through an optocoupler chip, ensuring the safety and stability of signal transmission, preventing the propagation of electrical faults, and allowing signal transmission between devices of different voltage levels. The overall design improves the enclosure structure's compatibility, stability, and electromagnetic compatibility, meeting the needs of multi-system devices working collaboratively in complex environments. This helps reduce the operational risks of multi-protocol information interaction devices under complex working conditions on ships, and helps improve operational stability.

[0012] Furthermore, the main control circuit board includes a main control board and a communication board that are connected to each other for data transmission. The main control board has through holes at its four corners, and the communication board has through holes at the positions corresponding to the through holes. The main control circuit board is stacked and installed by locking components after the through holes on the main control board and the through holes on the communication board are aligned.

[0013] In this way, the main control board and the communication board are stacked together. The data transmission connection between the two can be achieved by plugging in data ports or by using a data cable for short-distance transmission. The stacked installation of the main control board and the communication board allows for a more reasonable distribution and installation of chips, electronic components and other components used for multi-protocol information interaction on the two circuit boards. This also helps to improve the circuit's heat dissipation efficiency, reduces the risk of high heat accumulation in local areas, and improves the heat dissipation efficiency of the circuit board.

[0014] Furthermore, the locking component includes a bolt and a copper support. The bolt includes a screw and a bolt head. The upper end of the copper support has a threaded hole. The screw passes through a through hole on the main control board and extends into the threaded hole at the upper end of the copper support to achieve a fixed installation between the main control board and the copper support. The lower end of the copper support passes through a through hole on the communication board and has an external thread. The bolt head is threaded and fitted onto the lower end of the copper support that extends out of the through hole, and a compressive force is applied toward the communication board. Thus, the locking component locks the main control board and the communication board together.

[0015] In this way, the copper support pillars facilitate the rapid conduction of heat generated by the main control board, thereby improving heat dissipation efficiency. The locking components provide a stable and reliable connection between the main control board and the communication board, enhancing the structural strength of the entire main control circuit board and improving the product's durability. At the same time, the detachable main control circuit board allows for the maintenance or replacement of the main control board or the communication board, and the design of the bolts and copper support pillars makes the disassembly process easier.

[0016] Furthermore, an insulating gasket is provided between the screw and the main control board.

[0017] In this way, the insulating gasket prevents direct contact between the screw and the main control board, providing electrical isolation to avoid electrical short circuits, thereby ensuring circuit safety and signal transmission stability.

[0018] Furthermore, the housing assembly is made of aluminum profile and is integrally formed with the mounting frame.

[0019] In this way, the use of aluminum profiles for the enclosure components ensures the durability and impact resistance of the enclosure, while the one-piece molding design enhances the strength and stability of the overall structure.

[0020] Furthermore, both side panels of the enclosure are provided with arc-shaped ventilation holes, and there are multiple ventilation holes, which are evenly distributed on the two side panels.

[0021] In this way, the ventilation holes on the two side panels of the enclosure create air convection, optimizing airflow and allowing heat to be dissipated more effectively from the inside of the enclosure, thereby improving the overall heat dissipation efficiency.

[0022] Furthermore, the four corners of the base plate are respectively provided with lower mounting feet extending outward from the base plate. The lower mounting feet are horizontally arranged with the base plate, and the lower mounting feet are provided with positioning holes.

[0023] In this way, the lower mounting feet increase the contact area between the enclosure and the surface of the mounting position, thereby improving the stability of the enclosure, reducing vibration and movement, and the positioning holes on the lower mounting feet allow the enclosure to be precisely fixed in the mounting position using bolts or other fasteners, ensuring the accuracy and convenience of installation.

[0024] Furthermore, the socket includes a power socket, a 1553B socket, an I / O socket, and a serial port socket, which are connected to the main control circuit board via internal connecting wires.

[0025] In this way, different sockets can support multiple communication protocols, thus ensuring the cabinet's compatibility with various communication modes. At the same time, by arranging the sockets on the same side of the cabinet, wiring becomes simpler, making the connections neater and more orderly, reducing cable mess and tangling, and lowering the possibility of failure.

[0026] The technical solution of this utility model has the following beneficial effects:

[0027] This invention employs an integrated enclosure structure, incorporating different functional modules within a single enclosure. This enables multi-system equipment to work collaboratively across multiple communication modes, resolving compatibility issues. The enclosure components and cover are detachably connected, facilitating inspection, repair, or replacement of faulty components on the main control circuit board within the enclosure. Furthermore, the enclosure, constructed from a single aluminum profile, provides excellent structural strength and heat dissipation, while its streamlined appearance contributes to a clean and compact design. The use of locking mechanisms to stack the main control board and communication board further enhances efficient heat dissipation, reducing the risk of heat buildup in localized areas and improving circuit board cooling efficiency. The copper support pillars between the main control board and communication board also contribute to improved heat dissipation. This invention satisfies the functional requirements of heat dissipation and multi-communication mode compatibility while also achieving a simple appearance and low cost. Attached Figure Description

[0038] like Figures 1 to 6 As shown, a multi-protocol information interaction device enclosure structure includes an enclosure assembly 2 with an opening on one side, and an enclosure cover 1 installed on the opening side of the enclosure assembly 2. The inner circumferential side of the opening side of the enclosure assembly 2 has a mounting frame that protrudes towards the inner cavity of the enclosure assembly 2. The side of the mounting frame facing the enclosure cover 1 has a recessed groove 3. The enclosure assembly 2 has mounting holes 301 evenly distributed at the mounting frame. The enclosure cover 1 has fixing holes 101 at the positions corresponding to the mounting holes 301. The enclosure assembly 2 is fixedly installed to the enclosure cover 1 by screws 4 after the mounting holes 301 at the mounting frame are aligned with the fixing holes 101 on the enclosure cover 1.

[0039] The housing assembly 2 includes an integrally formed housing and a bottom plate. The bottom plate is installed at the bottom of the housing. The housing is formed by a front panel 5, a rear panel, and two side panels 6. The housing assembly 2 has a main control circuit board inside. The main control circuit board has threaded holes 802 for fixing to the bottom plate. The bottom plate has threaded blind holes at the positions corresponding to the threaded holes 802. The main control circuit board is fixed to the bottom plate through the threaded holes 802 and the threaded blind holes on the bottom plate using countersunk screws 4.

[0040] The front panel 5 of the enclosure has multiple insertion holes 9, through which sockets 10 are installed.

[0041] In this invention, the enclosure assembly 2 and the enclosure cover 1 are connected in a detachable manner, which facilitates the inspection, repair, or replacement of faulty components on the main control circuit board inside the enclosure. The enclosure structure design provides good structural strength and integrity. The main control circuit board is fixed by threaded holes 802 and threaded blind holes on the base plate with countersunk screws 4, ensuring a stable installation. At the same time, the close contact between the main control circuit board and the base plate allows heat to be quickly transferred through the contact surface of the base plate, improving heat dissipation performance.

[0042] The working principle of this utility model is as follows: The socket 10 in this embodiment includes a power supply socket 10, a 1553B socket 10, an IO socket 10, and a serial port socket 10. The socket 10 is connected to the main control circuit board through internal connecting lines. The enclosure structure receives DC24V power from the power supply equipment through the power supply socket 10. After power conversion through an external power chip and a DC / DC power module, the power supply needs of the enclosure structure are met. The main control circuit board controls the 1553B bus through the built-in 1553B IP core. The 1553B is a serial data bus standard used in the aerospace field, supporting multiple communication modes, including broadcast (BC), remote terminal (RT), and multi-function terminal (MT). By connecting a 1553B transceiver and an isolation transformer, the enclosure structure can achieve redundant communication of the 1553B bus. The controller supports BC / RT / MT modes and supports transformer coupling / direct coupling access to the bus. The GPIO interface achieves electrical isolation through an optocoupler chip, which can achieve 24V electrical isolation and 10mA drive capability.

[0043] Thus, the multi-protocol information interaction device enclosure structure in this embodiment integrates power supply and multiple communication modes by equipping it with various sockets 10. The 1553B socket 10 achieves highly reliable 1553B bus communication through the 1553B IP core and redundant design built into the main control circuit board, supporting multiple communication modes and coupling methods. This means that even if one communication path fails, the other path can still ensure communication continuity, improving system reliability. The GPIO interface achieves 24V electrical isolation through an optocoupler chip, ensuring the safety and stability of signal transmission, preventing the propagation of electrical faults, and allowing signal transmission between devices of different voltage levels. The overall design improves the enclosure structure's compatibility, stability, and electromagnetic compatibility, meeting the needs of multi-system devices working collaboratively in complex environments. This helps reduce the operational risks of multi-protocol information interaction devices under complex working conditions on ships, and helps improve operational stability.

[0044] In this embodiment, the main control circuit board includes a main control board 7 and a communication board 8 that are connected to each other for data transmission. The main control board 7 has through holes 701 at its four corners, and the communication board 8 has through holes 801 at the positions corresponding to the through holes 701. The main control circuit board is stacked and installed by locking components after the through holes 701 on the main control board 7 and the through holes 801 on the communication board 8 are aligned.

[0045] In this way, the main control board 7 and the communication board 8 are stacked together. The data transmission connection between the two can be achieved by plugging in a data port or by using a data cable for short-distance transmission. The stacked installation of the main control board 7 and the communication board 8 allows for a more reasonable distribution and installation of chips, electronic components and other components used for multi-protocol information interaction on the two circuit boards. This also helps to improve the efficient heat dissipation of the circuit, reduces the risk of high heat accumulation in local areas, and improves the heat dissipation efficiency of the circuit board.

[0046] In this embodiment, the locking component includes a bolt 11 and a copper support 12. The bolt 11 includes a screw and a bolt head. The upper end of the copper support 12 is provided with a threaded hole. The screw passes through the through hole 701 on the main control board 7 and extends into the threaded hole at the upper end of the copper support 12 to achieve fixed installation between the main control board 7 and the copper support 12. The lower end of the copper support 12 passes through the through hole 801 on the communication board 8, and the lower end of the copper support 12 has an external thread. The bolt head is threaded and fitted onto the lower end of the copper support that extends out of the through hole and applies a compressive force toward the communication board 8, thereby locking the main control board 7 and the communication board 8 together through the locking component.

[0047] In this way, the copper support 12 facilitates the rapid conduction of heat generated by the main control board 7, thereby improving heat dissipation efficiency. The locking components provide a stable and reliable connection between the main control board 7 and the communication board 8, enhancing the structural strength of the entire main control circuit board and improving the durability of the product. At the same time, the detachable main control circuit board allows for the maintenance or replacement of the main control board 7 or the communication board 8.

[0052] In this embodiment, both side panels 6 of the box body are provided with arc-shaped ventilation holes 16. There are multiple ventilation holes, which are evenly distributed on the two side panels 6.

[0053] In this way, the ventilation holes 16 on the two side panels 6 of the cabinet form air convection, optimize air flow, and allow heat to be dissipated more effectively from the inside of the cabinet, thereby improving the overall heat dissipation efficiency. At the same time, forming convection ventilation holes 16 can also reduce the noise generated by active cooling equipment such as cooling fans.

[0054] In this embodiment, the four corners of the base plate are respectively provided with lower mounting feet 14 extending outward from the base plate. The lower mounting feet 14 are horizontally arranged with the base plate, and the lower mounting feet 14 are provided with positioning holes 15.

[0055] In this way, the lower mounting feet 14 increase the contact area between the enclosure and the surface of the mounting position, thereby improving the stability of the enclosure, reducing vibration and movement, and the positioning holes 15 on the lower mounting feet 14 allow the enclosure to be precisely fixed in the mounting position using bolts 11 or other fasteners, ensuring the accuracy and convenience of installation.

[0056] In this embodiment, the socket 10 includes a power supply socket 10, a 1553B socket 10, an I / O socket 10, and a serial port socket 10. The socket 10 is connected to the main control circuit board via internal connecting wires.

[0057] In this way, multiple communication protocols can be supported through different sockets 10, thus ensuring the cabinet's compatibility with various communication modes. At the same time, by arranging the sockets 10 on the same side of the cabinet, the wiring is simpler, making the connection wires neater and more orderly, reducing cable mess and tangling, and lowering the possibility of failure.

At the same time, the enclosure is made of aluminum profile and is self-contained, thus providing good structural strength and heat dissipation performance. Moreover, its appearance is that of a single unit, providing a neat and compact appearance. The main control board 7 and the communication board 8 are stacked and installed using locking components, which helps to improve the efficient heat dissipation of the circuit, reduces the risk of high heat accumulation in local areas, and improves the heat dissipation efficiency of the circuit board. The design of the copper support 12 between the main control board 7 and the communication board 8 also helps to improve heat dissipation performance.
