Specific embodiment
The invention is further described with the following Examples.
Embodiment 1
As described in Figure 2, a kind of underwater positioning device of the invention, including the coiler device 41 that subject wears can be positioned
With the cable 42 being wound on coiler device 41, wherein coiler device 41 includes unreeling mechanism, and the unreeling mechanism is provided with backrush roller
411 and to backrush roller 411 apply backrush power torsion mechanism, the one end of cable 42 is connected to backrush roller 411, real-time in torsion mechanism
Backrush roller 411 is applied in the presence of backrush power, cable 42 completely can be wound to winding in the absence of external forces
Device 41, the other end of cable 42 is provided with the floating positioner 43 for swimming in the water surface, by increase floating positioner 43 with
The contact area of the water surface, makes buoyancy of the floating positioner 43 in water be slightly larger than backrush power of the unreeling mechanism to cable 42, with
So that the underwater positioning device is into floating positioner 43 still floats on the water surface and cable 42 is in and tightens shape afterwards under water
State.The satellite fix that be provided with floating positioner 43 carries out wired data communication with the control platform on the bank/pond side is filled
Put, the satellite positioning device is made up of GPRS inductors, the horizontal level that GPRS inductors position experiencer in real time is transferred to control
Platform processed.
Coiler device 41 is additionally provided with the linear measure longimetry for carrying out wired data communication with the control platform on the bank/pond side and fills
Put, the length-measuring appliance is included for detecting that the backrush roller 411 rotates the rotation monitoring device of the number of turns and rotation direction.Tool
Body ground, with reference to Fig. 5, rotating monitoring device includes light emitting diode 412 and photoelectrical coupler 413, and wherein light emitting diode 412 sets
Put on the axial plane of backrush roller 411, and photoelectrical coupler 413 is located at and is aligned in the upper right side of backrush roller 411, and photoelectrical coupler 413
Light emitting diode 412 on the axial plane of backrush roller 411.Because the stronger output voltage of light degree of illuminating of photoelectrical coupler 413 is higher, and
Light emitting source gets over the light degree of illuminating of dipped beam electric coupler 413 by force from photoelectrical coupler 413, so backrush roller 411 does not rotate one enclosing, hair
Light source from photoelectrical coupler 413 with a distance from have far-near-remote change, its output voltage uprises step-down again by low.Therefore turn
Dynamic monitoring device by comparing time of time that the output voltage of photoelectrical coupler 413 in each cycle is uprised and step-down, just
The rotation direction of backrush roller 411 can be obtained, specifically, monitoring device is rotated by judging the output voltage of photoelectrical coupler 413 for upper
Whether the time of the trend of liter can shorter than the time that its output voltage is downward trend, if then backrush roller 411 is rotate counterclockwise,
If otherwise backrush roller 411 is the rotation of positive hour hands;Meanwhile, rotate monitoring device calculate the output voltage of photoelectrical coupler 413 uprise or
The number of times of step-down then rotates the number of turns to obtain backrush roller 411.The backrush of unreeling mechanism described in length-measuring appliance real-time monitoring is moved
Make(Rolling back action is the rotation number of turns and rotation direction of backrush roller 411), to measure to obtain the cable 42 that discharges of the unreeling mechanism
Length, so as to position the submerged depth of experiencer, and transmit to control platform.
The invention positions the horizontal level of experiencer by the floating positioner 43 of satellite positioning device in real time, leads to
The rolling back action of length-measuring appliance monitoring unreeling mechanism is crossed to measure the length of the cable 42 that the unreeling mechanism discharges, so that
Position the submerged depth of experiencer.Compared with prior art, the invention need not use expensive depth calibrator,
Cost is relatively low.
