Description
Technical field
The present invention relates to deep-sea observation technology fields, and in particular to a kind of submarine observation network master base station underwater in-situ test system
System and method.
Background technology
Submarine observation network is by the parts such as bank base station, power supply and communication equipment, extra large cable, seabed master base station, scientific observation equipment
Composition, for implementing a wide range of round-the-clock real-time and long-continued observation to ocean interior, it is therefore an objective to fundamentally refresh people
Class recognizes and the traditional concept of observation ocean, can be that China brings revolutionary variation to the exploration of ocean, serve simultaneously
The correlative studys such as national marine safety, deep sea energy source and development of resources, marine environmental monitoring, disaster prewarning and forecasting.
Seabed master base station is the equipment of plugging into for connecting extra large cable and scientific observation equipment in submarine observation network, is that electric energy supplies
It gives, the hinge of plugging into of data transmission and communication control, major function has：
1, it realizes conversion of the electric energy from high pressure to mesolow, uninterruptible power is provided for scientific observation equipment；
2, the convergence and transmission of scientific observation equipment institute gathered data are realized；

Seabed master base station test is divided into test and seabed on the bank and tests two parts, and test content includes：
1, power supply output is tested, and is for testing the states such as port output voltage of plugging into, output power, output switch control
It is no normal；
Whether 2, communication function is tested, normal for tests data-link transmission state；
3, load testing, when changing or break down for test load the adaptability of master base station and quickly every
It is whether normal from ability；
Whether 4, clock test is normal for test clock synchronizing function.
Prior art test process is as follows：
First stage tests on the bank：It needs to carry out function and performance test using general purpose test equipment before master base station encapsulation,
It can be tested by two methods after encapsulation：The first will be tested after cable is connect with cavity again by above-mentioned general
Test equipment carries out functional test；Second is to carry out running performance test by connecting scientific observation equipment.
Second stage seabed is tested, and scientific observation equipment is plugged port of plugging by wet using underwater robot (ROV)
It is connected to after master base station and directly carries out testing results.
During submarine observation network construction, master base station is individually laid with scientific observation equipment, first lays master base station, is waited for
Entire submarine observation network trunk (bank base station-extra large cable-master base station) all be connected to and it is working properly after, then lay related science and observe and set
It is standby.Whether when laying scientific observation equipment, how judging that it is connected to master base station and plugs into can work normally as one behind port
A technical barrier, the prior art are only plugged scientific observation equipment after port of plugging into is connected to master base station just by wet in ROV
It is able to verify that whether correlation function is normal, this is the construction of submarine observation network whole system, especially later stage scientific observation instrument
It lays and increases great uncertainty.In addition, the scientific observation equipment once accessed can not work normally, staff can not
Failure judgement is happened at master base station and plugs into port or scientific observation equipment itself actually, this problem can not only postpone sea
Operation on the sea cost and risk can be also significantly greatly increased in construction speed.

For remote monitoring seabed observation network node operating status and the bank station of data management.Wherein, node main control board is distinguished
With fault diagnosis subsystem phase outside fault diagnosis subsystem inside energy fault diagnosis subsystem, node module body and node module body
Connection, the related fault-signal of real-time acquisition system operating status, and being communicated with bank station holding, at any time diagnostic system failure.
Above-mentioned patent " fault diagnosis system for submarine observation network nodes " although in also devise node module body internal fault
Fault diagnosis subsystem outside diagnostic subsystem and node module body, but it mainly sets intra-node failure and external observation
It plugs into port voltage when standby and electric current is monitored, only have the function of the power supply monitoring after scientific observation equipment is connected, therefore
Its system diagnostics function is simultaneously not perfect.Before the present invention can be very good to lay to scientific observation equipment after monitoring master base station is laid
This period master base station simulation run with load state, achieve the purpose that grasp master base station in real time and plug into port performance and state,
Reliable guarantee is provided for the access of scientific observation equipment, patent " fault diagnosis system for submarine observation network nodes " can not play this
The effect of invention.
In addition, the optical communication link design in entire submarine observation network is completed and after coming into operation, the quality of optic communication with
Reliability can with the working time increase, line maintenance the problems such as appearance and decrease.Underwater in-situ proposed by the present invention
Test equipment has attenuated optical signal power of test, can detect the decaying nargin of current optical communication network in real time, is tieed up for the later stage
It repaiies to extend with system and reference frame is provided, and patent " fault diagnosis system for submarine observation network nodes " can not play the present invention's
Effect.
In addition to this, master base station cavity is all made of pressure-resistant seal design, and externally only port of plugging into is plugged there are wet after sealing.
The prior art mainly before cavity package, utilizes electronic load, oscillograph, Network Analyzer, time Synchronization Analysis instrument etc.
General purpose test equipment carries out test and functional verification；And after cavity package, can only by test cable connect with cavity into
Row simple test, before especially at sea laying master base station, aboard ship there is no effective means to judge that master base station is plugged into function
Whether normal, only connecting real scientific observation equipment could be judged indirectly, lack the special auxiliary of necessary master base station
Test equipment.
