Abstract
The invention discloses a multi-node connection shore-based simulation test system for a seafloor observatory network. The system comprises a power supply, n switches, and n shore-based electric energy test systems and n seafloor detecting instruments which are in one to one correspondence with the n switches, wherein n=1-8. Each shore-based electric energy test system comprises an isolation sampling module, a digital-to-analog conversion chip, a data processing chip and an upper computer monitoring system which are sequentially connected, wherein the an electric energy output end of the power supply is connected with an input end of a connection box system, n output ends of the connection box system are connected with input ends of the n switches respectively, the output end of each switch is divided into two ways, one way is connected with a seafloor detecting instrument, and the other way is connected with the shore-based electric energy test systems. The system is suitable for shore-based electric energy simulation test before underwater instruments of the seafloor observatory network are placed, reliability and stability of electric energy supply are improved, and unstable factors which can possibly induce system crash are eliminated.

Technical field
The present invention relates to the bank basic mode that the seabed observation network multinode plugs into and intend test macro, be particularly useful for carrying out the electric imitating test of bank base laying seabed observation network under water before each instrument and equipment.
Background technology
The plug into the most basic function of box of seabed is conversion and distribution to electric energy, and what need to realize is to provide correct reliably electric energy to supply with to all kinds of instruments of scientific exploration under water.Electric energy need to be changed and distribute, and this is one of vital task of submarine observation system.Commercial power is through after the transformation, can not be directly used in various scopes after delivering to the seabed by key optical cable or cable, and middle must must have a conversion equipment.Plug into device for converting electric energy in the box, the electric energy with key optical cable or cable transmit by step-down, converts the applicable electric energy form of detection instrument to, and this task is born by the seabed box of plugging into.
In the environments such as subsea of complexity, require seabed observation network can correctly finish the supply of electric energy, the fault that occurs for whole system simultaneously also will have certain pre-diagnosis and processing power, and these all need highly reliably to realize based on the box device of plugging into of joint technology under water.The real-time energy state parameter that places the abyssopelagic box system that plugs into, habitata instrument to be in operation in the real work all plays vital effect to collection, processing and the transmission of data.Thereby plug into box system and habitata instrument running status are tested and carried out fault diagnosis is very necessary and difficult.
To sum up, deep sea equipment is tested before entry work, each technical indicator, the parameter of its electric energy part of measurement and monitoring, and understand its stability and reliability, thereby the weak link that may exist in the simultaneously understanding system is improved, and is a kind of necessity and wise way.
Summary of the invention
The objective of the invention is to propose the bank basic mode plan test macro that a kind of seabed observation network multinode is plugged into, carry out power test in the simulated environment on the coast seabed observation network is entered wetting system.
The bank basic mode that seabed observation network multinode of the present invention is plugged into is intended test macro, comprise power supply, the box system plugs into, n switch, respectively with n switch one to one n bank base power test system and n habitata instrument, n=1～8, said bank base power test system comprises the isolation sampling module, the D/A switch chip, data processing chip and Monitor Computer Control System, the electric energy output end of power supply links to each other with the input end of the box system that plugs into, n output terminal of the box system that plugs into links to each other with the input end of n switch respectively, the output terminal of each switch is divided into two-way, the one road connects the habitata instrument, and another road links to each other with the input end of isolation sampling module, and the output terminal of isolation sampling module links to each other with the input end of analog-digital chip, the output terminal of analog-digital chip links to each other with the input end of data processing chip, and the output terminal of data processing chip links to each other with Monitor Computer Control System by the RS232 serial communication interface.
During simulation test, power supply is converted to negative high voltage direct current (take-10kV as example) with civil power, by transmission cable with delivery of electrical energy in the box system that plugs into, the box system that plugs into is converted into mesolow direct current (take 375V or 48V as example) with high voltage direct current, for n the habitata instrument in seabed provides work energy, n switch controlled respectively the electric energy supply of corresponding habitata instrument, when switch closure, by isolating sampling module to sampling from the voltage signal of the box system that plugs into and isolating, the analog quantity of isolation sampling module output is converted to digital quantity through analog-digital chip and inputs to data processing chip and carry out data and process, then be transported to Monitor Computer Control System by the RS232 serial line interface, in Monitor Computer Control System, carry out data processing and demonstration and storage, compare with setting threshold according to the data of gathering, whether break down with plug into box system or habitata instrument of judgement.
The bank basic mode that seabed observation network multinode of the present invention is plugged into is intended test macro can be to the instrument and equipment of seabed observation network submarine platform, comprise the box system that plugs into, the habitata instrument carries out the power test before the entry in simulated environment, comprise the surge current test, the earth fault test, the steady-state characteristic test, the automatic test of the multiparameters such as short-circuit test, to get rid of potential safety hazard, determine optimum running status, guarantee the stable of each instrument and equipment of sea bed observation platform, when long, effectively operation, the negative effect that the power failure of lowering apparatus equipment is brought whole observation grid, improve to greatest extent the result of use of seabed observation network submarine platform, greatly reduce electric energy network failure probability, for the safe operation of seabed observation network provides strong assurance.
