Problems solved by technology

[0003] It is precisely because the current commercial access layer switches are not designed in accordance with the relevant military standards and specifications, so it is difficult to apply them to warships, and cannot pass the corresponding test assessment, and they cannot be used in harsh environments such as vibration, shock, salt spray, electromagnetic interference, etc. ) under stable work

Embodiment Construction

[0037] The present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.

[0038] Such as figure 1 As shown, the naval access layer switch equipment consists of four parts: aviation socket board 1, box body 2, installation base 3 and switch module 4, as well as filters, shock absorbers, and temperature control systems.

[0039] The naval access layer switch is mainly made of commercial Cisco modular switches for naval reinforcement. This type of commercial machine has great flexibility and expandability, and users can choose modules of different quantities, different rates and different interface types at will to meet different network requirements. Moreover, most modular switches have high performance (such as backplane bandwidth, forwarding rate and transmission rate, etc.), strong fault tolerance, support for redundant backup of switching modules, and often have hot-swappable dual power supplies, To ensure the power sup...

Abstract

The invention relates to shipborne access layer switch equipment and a shipborne access layer switch equipment assembling and reinforcing method. The shipborne access layer switch equipment is mainly composed of an aviation socket board, a housing, a mounting base and a switch module. The housing is made of aluminum alloy and is manufactured through processes of sandblast, nickel plating and anticorrosive paint applying. A mounting base is fixed at the back of the housing. A vibration damping pad is added between the inner bottom of the housing and the switch module. Furthermore vibration damping rings are arranged at a portion between the front surface of the switch module and the housing, a portion between the back surface of the switch and the housing, a portion between the left surface of the switch module and the housing and a portion between the right surface of the switch module and the housing. The aviation socket board is connected with the switch module through a cable. Discrete elements of the circuit board in the switch module are fixed through 1345 glue. Each connecting slit of the housing is provided with conductive lining material. The shipborne access layer switch equipment and the shipborne access layer switch equipment assembling and reinforcing method can effectively satisfy requirements for heat radiation performance, vibration resistance, impact resistance, water resistance, moisture resistance, dust resistance and electromagnetic compatibility of commercial network equipment in a shipborne environment, and furthermore satisfy a requirement for the access layer network equipment by the shipborne electronic information system.

Description

technical field [0001] The invention relates to ship-borne network information equipment, in particular to a ship-used access layer switch device and an installation and reinforcement method for the device. It mainly provides core network access and switching services for the ship's electronic information system. Background technique [0002] The mainstream commercial access layer switches currently on the market are mainly suitable for use in the indoor environment of land buildings with good environmental conditions. Generally speaking, the switch in the indoor environment on land only needs to be used bare metal, without additional protection facilities. For harsh environmental conditions such as ships, due to the influence of temperature, humidity, air pressure, impact, interference, etc., the safety and stability of bare metal use will be greatly reduced. For harsh environmental conditions such as ships, there are currently no special design measures. [0003] It is ...
