Embodiment
Monitoring distribution of vertical depth temperature field of ocean in real time device of the present invention comprises following structure, hereinafter will be described in detail this with reference to accompanying drawing.
As shown in Figure 1, the present invention includes a special-purpose buoyancy tank 1 that can swim on the water surface, in the special-purpose buoyancy tank 1 described temperature is housed and surveys main frame 2, temperature is surveyed an end that connects transmission sensing optical cable 4 on the main frame 2, the other end of transmission sensing optical cable 4 connects deep water grappling mooring device 5, and this deep water grappling mooring device 5 can be constrained in special-purpose buoyancy tank 1 marine certain regional location.
Hanging a weight special-purpose buoyancy tank 1 time with rope, is that special-purpose buoyancy tank 1 can reach the certain degree of depth in seabed according to actual needs.On fixing on the rope that is this weight, transmit the maritime end of sensing optic cable 4 straight vertical.
Transmission sensing optical cable 4 vertically is connected to the deep water grappling mooring device 5 on the sea bed.This transmission sensing optical cable 4 vertically leads to the seabed by deep water grappling mooring device 5, thus on the transmission sensing optical cable 4 each point Temperature Distribution just the ocean along the temperature field of depth vertical distribution.This transmission sensing optical cable 4 has thermally sensitive special structure, and both as the transmission medium of light signal, as the sensing element of ocean depth vertical temperature distribution, energy propagated laser pulse signal can be responded to optical cable ambient temperature information on every side in real time again.This transmission sensing optical cable 4 has very strong anti-seawater corrosion ability, anti-tens myriametres undersea seawater side pressure ability and resistance to tension, and this optical cable also possesses the responsive to temperature ability that rapid response ambient temperature changes.
For transmission sensing optical cable 4 can be straightened, temperature is surveyed main frame 2 and is linked to each other by a tensioning system with transmission sensing optical cable 4, makes transmission sensing optical cable 4 be in tensioning state all the time.
Above-mentioned deep water grappling mooring device 5 can use the berth anchor of usefulness of boats and ships, anchor directly is connected the lower end of transmission sensing optical cable 4.This anchor can arrive the seabed of ten thousand metres with interior any degree of depth, and special-purpose buoyancy tank 1 fixing grain bin can be floated in certain position, zone of action, sea.
Temperature is surveyed on the main frame 2 and is provided with wireless transmit antenna 21, temperature is surveyed main frame 2 and by this wireless transmit antenna 21 depth vertical distribution temperature field, the ocean numerical value that detects is transmitted into satellite or near water front reception base station in real time, thereby realizes the purpose to the real-time monitoring in depth vertical distribution temperature field, ocean.
Temperature is surveyed on the main frame 2 a GPS positioning system is set, and the GPS positioning system can accurately be located the position of special-purpose buoyancy tank 1.
The monitoring distribution of vertical depth temperature field of ocean in real time method of using said apparatus to carry out temperature monitoring comprises the steps:
At first, temperature is surveyed main frame 2 by specific controller, produce specific control, make a series of laser pulses of a specific width of laser instrument output, be injected in the vertical transmission sensing optical cable 4 as for sea bed that gos deep in the ocean, this a series of laser pulse is conduction downward vertically in transmission sensing optical cable 4.
Because transmission sensing optical cable 4 vertically is in the seawater of different depth, different temperatures, can modulate laser pulse, return simultaneously continuously a series of temperature modulation that are transmitted different depth ocean around the sensing optic cable 4 dorsad the light pulse echoed signal, return along former road, get back in the controller of temperature detection main frame 2.
Then, the controller that temperature is surveyed main frame 2 carries out demodulating and decoding to the light pulse echoed signal of returning, and calculates the temperature information of seawater around the each point on transmission sensing optical cable 4 length, and then draws the vertical distribution situation of ocean temperature field.
At last, this temperature detection main frame 2 passes through public's wireless data transmission net or satellite returned data center by these ocean, place depth vertical temperature distribution data that wireless transmit antenna 21 will record.
The operation steps of concrete operation ocean depth temperature field distribution of the present invention real-time monitoring device is as follows: at first place special-purpose buoyancy tank 1 in the sea level location of premeasuring, one end of transmission sensing optical cable 4 is linked to each other with the detection main frame, the other end is fixed on the anchor cable, cast anchor on sea bed, special-purpose buoyancy tank 1 can be fixed, open the wireless transmit antenna 21 of surveying main frame simultaneously, open host power supply, this sniffer is promptly started working.
Fig. 2 is the fundamental diagram that temperature is surveyed main frame 2.The laser controller drive laser is sent a series of laser pulses among the figure, be injected in the transmission sensing optical cable 4 by the 1*2 splitter, propagate downward vertically along optical cable, on the way with transmission sensing optical cable 4 in special responsive to temperature medium bump and produce a series of light pulse echoed signals dorsad, after its light pulse echoed signal dorsad is back to the 1*2 splitter along former road, 8 ends by splitter, enter photoelectric commutator, carry out opto-electronic conversion, enter data acquisition and signal Processing after the conversion and carry out data processing, data-signal is handled the luminous power information of the laser instrument output of transmitting in conjunction with laser end, demodulate the temperature value that transmission sensing optical cable 4 each points distribute, because transmission sensing optical cable 4 is that Vertical Anchor fixes in the ocean, thereby its Temperature Distribution vertical temperature distribution of ocean depth just.Data-signal is handled by the temperature field data in real time emission of emitter with ocean depth vertical distribution and is sent out.
The present invention is mainly used in the real-time detection in vertical distribution temperature field, great depth ocean, also can be used for the real-time detection closed container, as the vertical temperature distribution of liquid in the large-scale oil storage tank.
Above-mentioned design example only is used for that the present invention will be described, does not constitute the restriction to the claim scope, and other substantial equivalence means that it may occur to persons skilled in the art that are all in claim scope of the present invention.
