[0048] This module is designed with the same external dimensions and slot installation method as other marine data acquisition card modules, meeting the requirement of consistent installation space and solving the problems of insufficient space and crowded equipment on board. It has hot-swappable function and uses European plug connector interface to realize power and communication transmission, reducing the number of external cables and reducing the manpower, material resources and financial resources required for laying individual cables. It also avoids the risk of cable loss and signal transmission weakening due to cable passing through compartments.

[0049] The modules provided in the above embodiments have the advantages of high versatility and high reliability compared with the prior art.

[0050] High versatility: The design has the same external shape, size and slot installation method as other marine acquisition card modules. It can be directly installed using the existing marine distributed acquisition box backplane rack, without the need for a separate installation bracket, saving unnecessary installation space and cost.

[0051] High reliability: It uses the same European plug connector interface as other marine data acquisition modules for power and communication transmission, reducing the use of cables and avoiding problems such as incorrect cable connection or breakage. At the same time, the fiber optic sensing and analysis module has hot-swappable functionality, so inserting or removing it will not affect the normal operation of the system.

Multiple data acquisition card modules are assembled on the same backplane frame 10 using bolts and fasteners 9. The interface between the backplane frame and the data acquisition card modules is an Omega connector 11.

[0053] like Figure 6As shown, the light source module 2, data acquisition card module 4, and power supply module 6 of the slot-type fiber optic sensing and analysis module are bolted to the inside of the housing 3. With the power supply module 6 fixed, the European connector 8 is positioned precisely at the bottom slot of the housing 3. The optical interface socket 7 is bolted to the outside of the housing 3. The left cover plate 1, housing 3, and right cover plate 5, when assembled with bolts, meet the same external dimensions as other marine data acquisition card modules. The external interfaces of this module are the optical interface socket 7 and the European connector 8. The optical interface socket 7 is used for external optical signal input, and the European connector 8 is used for power input and communication signal input / output.

[0054] The marine data acquisition box backplane rack 10 is part of the marine distributed data acquisition box integrated environment. It integrates a bus circuit to provide power and Ethernet communication signals for each data acquisition card module.

[0055] The slot-type fiber optic sensing analysis module has a pair of European plug connectors 8 and 11. During installation, the European plugs are aligned and then fastened to the back panel frame 10 using bolts 9.
