Description

Technical Field

[0001] This invention relates to the field of ship intelligent control equipment technology, specifically a highly protected miniaturized intelligent controller. Background Technology

[0002] Intelligent control equipment for ships is mainly used in intelligent control scenarios of modern ship equipment. With the rapid development of ship equipment, this type of controller is being upgraded towards miniaturization, shock resistance, and anti-interference. Its performance directly affects the operational reliability of ship equipment in complex marine environments and is a core component of ship electronic systems.

[0003] Currently, most intelligent controllers in the naval field adopt PLC or VPX board solutions. Due to the limitations of their structural form, these boards cannot meet the shock resistance and electromagnetic compatibility performance required by the naval environment when used independently. They require additional protective shells for structural reinforcement and electromagnetic shielding. This external protection configuration directly leads to a significant increase in the overall size of the controller, resulting in technical problems such as limited installation space and a greatly reduced scope of application. It cannot be adapted to the limited installation space inside ships, nor can it meet the actual usage requirements of harsh ship operating conditions. At the same time, this type of integrated controller requires complete disassembly and repair when a failure occurs, making board upgrades and functional expansion difficult and maintenance costs high. Summary of the Invention

[0004] The purpose of this invention is to provide a highly protected, miniaturized intelligent controller with the advantages of integrated vibration isolation, modular plug-and-play, full-link shielding, and compact structure, effectively solving the problems of existing ship controllers being bulky, having limited installation space, and lacking shock resistance and electromagnetic compatibility performance.

Detailed Implementation

[0029] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0030] Example 1

[0031] To achieve miniaturized integration and shock resistance of ship intelligent controllers, and to address the issue of excessive size resulting from the need for additional reinforced housings in traditional controllers, such as... Figures 1 to 5 As shown, one embodiment of the present invention provides a high-protection miniaturized intelligent controller, including an integrated vibration isolation mounting assembly 1. The integrated vibration isolation mounting assembly 1 serves as an integrated vibration isolation and reinforcement base for the equipment, integrating a vibration isolation and buffer structure, eliminating the need for additional reinforcement structures. The integrated vibration isolation mounting assembly 1 includes a mounting base plate 11, a vibration isolator mounting seat 12, and a wire rope vibration isolator 13. The vibration isolator mounting seat 12 is fixedly mounted to the upper surface of the mounting base plate 11 using M4 stainless steel hexagonal bolts. The wire rope vibration isolator 13 is assembled onto the vibration isolator mounting seat 12 via connecting flanges at both ends. The upper end of the wire rope vibration isolator 13 is fixedly connected to the upper bus mounting seat 21 via bolts. This is used to buffer the impact and vibration generated by the ship environment, meeting the impact resistance and vibration isolation requirements for ship equipment specified in GJB150.18A-2009.

[0032] A bus plug-in positioning assembly 2 is fixedly mounted on the upper part of the integrated vibration isolation mounting assembly 1. The bus plug-in positioning assembly 2 includes a bus mounting base 21. The bottom of the bus mounting base 21 is fixedly connected to the upper end of the wire rope vibration isolator 13 by bolts. A bus backplate is fixed inside the bus mounting base 21 by bolts, providing a mounting carrier and signal transmission bus for the sub-function boards. Sub-function board insertion guide pins 22 are vertically fixed on the upper surface of the bus mounting base 21. Two symmetrically distributed sub-function board insertion guide pins 22 are set at each sub-function board assembly station to accurately position the insertion position of the sub-function board and ensure accurate engagement of the communication connector. A sub-function board communication connector 23 is fixedly set at the center of the assembly station of the bus mounting base 21. The sub-function board communication connector 23 adopts a high-reliability pin-type board-to-board connector with anti-misinsertion key design. Its pins are soldered to the bus backplate to realize signal transmission between the sub-function board and the bus backplate.

[0033] Example 2

[0034] To achieve end-to-end electromagnetic shielding and improved environmental adaptability of the equipment, and to address issues such as insufficient electromagnetic interference and waterproof / dustproof performance under shipboard conditions, such as... Figure 1 , Figure 3 , Figure 4 As shown, in this embodiment, the sub-functional board assembly station edge of the bus mounting base 21 is provided with a shielding material embedding groove 24. The depth of the shielding material embedding groove 24 is 3-5mm and the width is 2-4mm. It is used to embed special shielding materials. The special shielding materials include, but are not limited to, electromagnetic shielding materials commonly used in ship environments, such as conductive rubber strips, tin-plated copper braided mesh pads, and beryllium copper spring sheets.

[0035] The bus plug-in positioning assembly 2 is equipped with a sub-function board protection operation assembly 3. The sub-function board protection operation assembly 3 adopts a modular pluggable structure design, which includes a sub-function board protection shell 31. The sub-function board protection shell 31 is die-cast from 6061-T6 aluminum alloy and anodized. It is used to fix and protect the circuit board of the sub-function board. The sub-function control circuit board 37 is fixedly installed inside the sub-function board protection shell 31 by copper pillars and bolts. The contact surface between the sub-function board protection shell 31 and the bus mounting base 21 presses the shielding material in the shielding material embedding groove 24 to form a closed shielding cavity, while achieving IP65 level waterproof and dustproof protection, greatly improving the environmental adaptability of the board.

[0036] The side of the sub-function board protective housing 31 is equipped with an external wiring aviation connector 32. The external wiring aviation connector 32 adopts a pluggable circular aviation connector with an IP67 or higher protection rating. Its pins are soldered to the corresponding sub-function control circuit board 37 to ensure the reliability of external wiring connections. The high-protection pluggable structure reduces contact resistance and internal signal transmission loss. At the same time, the connector's own metal shell shielding structure further enhances the signal anti-interference capability. The side of the sub-function board protective housing 31 integrates heat dissipation fins, which are integrally extruded with the sub-function board protective housing 31. The fin spacing is 3mm and the height is 15mm. This is used to quickly dissipate the heat generated by the sub-function control circuit board 37 during operation, ensuring long-term stable operation of the equipment in an ambient temperature range of -40℃ to +85℃.

[0037] Example 3

[0038] To facilitate convenient equipment debugging, operation and maintenance, and functional expansion, and to solve the problems of cumbersome maintenance and inconvenient upgrades of traditional controllers, such as... Figure 1 , Figure 4 , Figure 5 As shown in this embodiment, the top of the sub-function board protective shell 31 is provided with a flip-type debugging interface 33. The flip-type debugging interface 33 includes a USB Type-C debugging interface and an RS232 serial debugging interface. A waterproof rubber sealing ring is provided on the outside of the interface. The flip is connected to the sub-function board protective shell 31 through a pivot. In the non-debugging state, the flip is closed and the sealing ring is pressed. During debugging and maintenance, it can be opened directly without disassembling the shell to complete the debugging operation.

[0039] The outer surface of the sub-function board protective housing 31 is sequentially provided with a sub-function board display panel 38, working status indicator lights 36, sub-function board name label 35, and operation instruction QR code label 34. The sub-function board display panel 38 uses an OLED display screen and is connected to the sub-function control circuit board 37 via a flexible cable to provide an operating interface for users to operate the device visually. The working status indicator lights 36 include a power indicator light, a running indicator light, and a fault indicator light, each corresponding to a different working state. The sub-function board name label 35 is used to display the name and model of the sub-function board. The operation instruction QR code label 34 is used to display the operation instructions and technical manual of the sub-function board, which can be easily accessed by scanning the code.

[0040] The bottom of the sub-function board protective housing 31 has a positioning hole that matches the sub-function board insertion guide pin 22. The sub-function board protective housing 31 is positioned and inserted into the sub-function board insertion guide pin 22 through the positioning hole. The sub-function board communication connector 23 precisely engages and conducts with the corresponding connector on the bottom of the sub-function control circuit board 37. Each sub-function board is independently inserted into a different station on the bus backplane and can be individually disassembled and replaced without powering down other normally functioning boards, which facilitates later maintenance, board upgrades, and function expansion.

[0041] Assembly and usage method of the present invention

[0042] First, assemble the equipment. Secure the vibration isolator mounting base 12 to the upper surface of the mounting base plate 11 using M4 stainless steel hex bolts. Then, secure the wire rope vibration isolator 13 to the vibration isolator mounting base 12 and the bus mounting base 21 using bolts on the upper and lower flanges, completing the assembly of the integrated vibration isolation mounting assembly 1. Next, press-fit the sub-function board insertion guide pin 22 into the corresponding holes of the bus mounting base 21. After welding the sub-function board communication connector 23 to the bus backplane, fix the bus backplane to the inside of the bus mounting base 21 using bolts. Create a shielding material embedding groove 24 at the edge of the assembly station of the bus mounting base 21 and embed special shielding material. Use a special pressure strip to press the shielding material firmly into the bottom of the groove, completing the assembly of the bus insertion and positioning assembly 2.

[0043] The sub-function control circuit board 37 is fixedly installed inside the aluminum alloy sub-function board protective housing 31 using copper pillars and bolts. The external wiring aviation connector 32 and the flip-type debugging interface 33 are assembled and soldered in sequence. The sub-function board name label 35 and the operation instruction QR code label 34 are affixed to the outer surface of the sub-function board protective housing 31. The sub-function board display panel 38 and the working status indicator light 36 are installed to complete the assembly of the single sub-function board protective operation assembly 3.

[0044] The assembled sub-function board protective shell 31 is vertically inserted downward along the sub-function board insertion guide pin 22 to the corresponding assembly station of the bus fixing base 21, so that the sub-function board communication connector 23 is precisely connected with the connector at the bottom of the sub-function control circuit board 37, and the bottom end face of the sub-function board protective shell 31 presses the shielding material in the shielding material embedding groove 24 to form a full-link electromagnetic shielding structure.

[0045] Using the mounting holes on the mounting base plate 11, stainless steel bolts are used to fix the equipment to the designated installation position on the ship. External cables are then connected to the external aviation connector 32, and the connector nuts are tightened to complete the overall installation. After the equipment is powered on, the sub-function board display panel 38 displays real-time operating parameters, the working status indicator 36 reflects the working status of the corresponding sub-function board, the wire rope vibration isolator 13 continuously buffers the vibrations and impacts generated by the ship's navigation, the fully enclosed shielding structure blocks interference from the complex external electromagnetic environment, and the heat dissipation fins on the side of the sub-function board protective shell 31 simultaneously provide natural heat dissipation.

[0046] When debugging and maintenance are required, simply open the flip-top of the debugging interface 33 to connect to external debugging equipment for parameter configuration and troubleshooting. When upgrading or expanding the functionality of a board, simply pull up the protective shell 31 of the corresponding sub-function board to complete the disassembly. After replacing the new sub-function board, reverse the process to complete the installation. The overall structure is compact with no redundant space, making it suitable for use in the confined spaces and harsh operating conditions of ships.

[0047] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics.
