Specific embodiment

A kind of preferred reality of the hydrothermal solution temperature sensor system based on ROV platform that the invention will now be described in detail with reference to the accompanying drawings Apply mode.

Fig. 1 shows a kind of specific embodiment of the hydrothermal solution temperature sensor system based on ROV platform of the present invention:

Being somebody's turn to do the hydrothermal solution temperature sensor system based on ROV platform as shown in Figure 1 includes ROV main body 1, and ROV main body 1 passes through logical News cable 13 is connect with host computer 12, and ROV main body 1 is connect with the power control terminal mouth 2 on pressure resistence cabin body 5, power control terminal mouth 2 It is mounted on pressure-resistant storehouse sealing cover 3, is also equipped with thermocouple connectivity port 1 and thermocouple connecting pin on pressure-resistant storehouse sealing cover 3 Mouthfuls 28, temperature collecting module 4 and data processing and communication module 6 are installed inside pressure resistence cabin body 5, pressure resistence cabin body 5 passes through watertight Cable 9 is connect with the temperature probe 11 being fixed on fixture 10.

The hydrothermal solution temperature sensor system based on ROV platform will be designed according to modular mode, major embodiment System is being divided into different modules according to different function, is passing through the control modes phase such as cable and mechanical structure between each module Connection, therefore this system has structure simple, the features such as clear function and stronger maintainability and operability.Temperature probe 11 For armoured thermocouple probe, temperature probe 11 accesses the lower pressure resistence cabin body 5 of water by the watertight cable 9 of vulcanizing treatment.Pressure resistence cabin body 5 Interior placement temperature collecting module 4, data processing and communication module 6, the pressure resistence cabin body 5 are general by extending out for the offer of ROV main body 1 Network interface realizes to control and connect with data processing system that control terminal completes the control to undersea detection part on deck with the water surface System, real-time reception hydrothermal vent temperature field data, and realize that temperature data such as shows, draws, stores and play back at the functions.

Measurement nozzle temperature is detected in hydrothermal activity investigation using very extensive using thermocouple.In the temperature of deep-sea hydrothermal In degree detection, common temperature sensor has thermocouple, metal fever resistance and thermistor.Wherein, thermocouple is often used in height The hydrothermal solution environment of temperature, and metal fever resistance or thermistor are commonly used for the cold junction compensation of thermocouple.This is because the structure of thermocouple It makes simply, sturdy and durable, easy to use, temperature-measuring range is wide, the high temperature measurement being suitble in adverse circumstances；And thermistor or metal The measurement accuracy of thermal resistance is high, and performance is stablized, and is suitble to the temperature measurement of the thermocouple cold junction environment in deep sea in-situ detection.Thermoelectricity It is even to use specialty metal as material, and have titanium as protection shell, the data measured are storable in data recording equipment On, also data directly can be transmitted back to deck control terminal and carry out real time data processing.

Design work after thermocouple probe model determines, in terms of Ying Jinhang mechanical dimension.According to the technology of sub- project Index, the maximum operating water depth of temp probe have reached deep-sea 4500m, and this requires temp probes at least to need pressure-resistant 45MPa. According to an initial estimate, the wall thickness of thermocouple sheath at least needs 4mm, and entire sleeve outer at least needs 20mm.In addition, in order to increase By force to the adaptability of ROV main body 1, reduces manipulator entrained by ROV main body 1 and grasping hygrosensor progress hydrothermal vent insertion Practical operation difficulty, thermocouple probe can be designed as corner-shape structure (linear structure can also be used), front end is maximum inserts Enter the probe portion of depth 200mm, rear end is the company of leading part.The sleeve outer of probe portion is designed as 20mm~25mm, length It is designed as 200mm；The sleeve outer of the company of leading part is designed as 16mm~20mm, Design of length 300mm.

Temperature acquisition in pressure resistence cabin body 5, data processing and communicating circuit are basis and the core of entire temperature-sensing system The heart is the bridge for connecting hydrothermal solution temperature signal and computer.The temperature signal that the circuit measures sensor carries out conditioning amplification Into appropriate range, the analog signal of input is converted into accessible digital signal by the AD conversion module of circuit, wait locate Reason is passed in host computer after finishing by communication module.

Since temperature probe 11 is designed as single-point, 8 points and 10 points, temperature collecting module 4 must have multichannel input work Energy.In view of 5 portability of pressure resistence cabin body and weight demands, using 9211 thermocouple acquisition module of NI.9211 module of NI is mark The thermocouple acquisition module of standardization only need to be equipped with corresponding K-type thermocouple connector, can directly be connected with K-type thermocouple, and Without other compensating lines and additional corrections.Also, its 24 internal AD provides the analog-to-digital conversion ability of degree of precision, can Entire hydrothermal solution temperature-sensing system is set to have lesser resolution ratio.

Thermocouple part has contemplated that pressure-resistant problem, and casing can tolerate 45MPa pressure, the pressure resistance of signal acquisition circuit part By designing a resistance to pressure cylinder of cylinder, by mode of the circuit package inside resistance to pressure cylinder, to protect transmission circuit.Pressure-resistant storehouse is quasi- Using 7085 duralumin, hard alumin ium alloy materials, in one side weight it is lighter than stainless steel very much, convenient for ROV main body 1 carry；On the other hand, Metal hardness is eager to excel much than polymer material, resistance to underwater collision.Meanwhile the anti-corrosion capability of aluminum alloy materials is also very strong, valence Lattice are also cheap compared with titanium alloy.

In terms of sealing joint, between temperature probe 11 and the resistance to pressure cylinder of transmission circuit, static seal mode is taken, is connected by flange It connects, and is equipped with deep-sea sealing ring and carries out watertight technological design.The other end of the resistance to pressure cylinder of transmission circuit, it is close that end cap portion designs twice Envelope groove is sealed, and junction portion uses 8 core deep-sea seal sockets.

The hydrothermal solution temperature sensor system based on ROV platform is combined using key equipment customization research and development and the system integration Mode carry out detailed design, carried out armoured thermocouple probe, thermocouple data acquisition module and data processing and biography respectively Defeated module, the design of the detailed technology of host computer display and control software three parts, system detailed design process have fully considered miniaturization, work The design requirement of journeyization and inventionization.

The above are merely the preferred embodiment of the present invention, it is noted that for those of ordinary skill in the art, Without departing from the concept of the premise of the invention, various modifications and improvements can be made, these belong to guarantor of the invention Protect range.
