| Modern warfare is informationized warfare,and how to stabilize and quickly transmit wartime information in a harsh environment is the key to winning a war.In this paper,a set of reinforced shipboard optical end communication devices for large military ships is developed in view of the requirements of moisture-proof,salt-proof,earthquake-proof,and anti-interference of complex electromagnetic environments of ship-borne communication equipment of maritime combat ships.The device uses optical fiber as the data transmission medium and consists of k VM(Keyboard Video Mouse)operating terminals,optical cables and uncompressed digital optical terminals.In this paper,the optical fiber transmission and photoelectric conversion technology are studied,the core hardware of the device is selected according to the various indicators of the military technical agreement,and the main core hardware and transmission link are studied,the system workflow is given,the bandwidth of the GTP(Gigabit Transceiver with Low Power)transceiver is calculated,and the physical interface electrical connector of each signal input and output is designed.The article focuses on the chassis structure design of the rugged shipboard optical end device and the electromagnetic compatibility design of the chassis,including the chassis structure size,heat dissipation design,chassis reinforcement,hole treatment,gap treatment and other aspects.The chassis has no heat dissipation holes,which enhances the heat dissipation by reducing the thickness of the chassis wall,increases the overall strength of the box by designing the wall stiffeners,and uses heat sinks for local chip high temperature for heat dissipation.By designing a waterproof groove at the sealing place of the box,the box is sealed with a conductive sealing rope for moisture-proof and salt-proof design.All electrical connectors use military aviation plugs.The shielding principle of metal materials is analyzed,and the gap of each electrical connector is treated by using conductive gaskets,which improves the shielding performance of the entire box,welds some permanent seams,and further calculates the shielding efficiency of the box after treatment.Finally,the article jointly debugs the whole machine system by building a debugging test platform for the whole machine and the supporting devices to jointly debug the environment.Combined with the full text content,the device system is more suitable for ship-to-ship communication than the existing commonly used ship-to-ship communication methods,the system transmission mode has strong anti-interference ability,and the transmission delay is less than satellite communication,which has high military application value for ship communication. |
