Description
Technical field
This utility model belongs to marine exploration equipment and reclaims field, particularly to a kind of phase place localizer beacon in this field
System.
Background technology
21 century is numerical ocean model, ocean to be developed, protection ocean, first has to understand ocean.People detect ocean from closely
Far-reaching sea is progressively moved towards in sea, and wherein a lot of marine exploration equipment need to sink to seabed, reclaims research, setting after work a period of time
During emerging, due to the impact of ocean current, often there is gap the position emerged, in addition with the position of input
The impact of wave, often makes equipment be difficult to find.In order to improve the response rate of oceanographic equipment, detecting devices generally requires binding
Beacon apparatus, beacon apparatus is provided that its location information (such as GPS information), according to this positional information, searches ship just
Target device can be easily found.
Prior art has GPS and two kinds of localizer beacon methods of tellurometer survey.
The principle of GPS localizer beacon method is: beacon is fixed on target-detection unit, and receptor is by user's control.Letter
It is provided with GPS module inside mark and receptor, all can obtain the gps coordinate of current location.When target-detection unit has worked,
When floating up from the bottom, it can discharge beacon, and beacon is started working, and it can constantly search gps signal, it is thus achieved that gps coordinate is believed
Breath, and by radio station, the gps coordinate of beacon Location is sent.
The main task of receptor is: (1) searches GPS and obtains the GPS seat of current location (i.e. receptor present position)
Mark；(2) receive, by radio station, the gps coordinate (i.e. the coordinate of beacon present position) that beacon transmits.Obtain the GPS that the two is local
After coordinate, receptor meeting comparison, resolving the two coordinate, it is thus achieved that the relative bearing between the two point and distance.
The method requires that beacon not only installs radio station but also install GPS module, and power consumption is big, and stand-by time is short；Because simultaneously need to
Radio station and GPS, it is necessary to install two antennas (and antenna is necessarily mounted at top), use the sealing means of cylindricality pressure-resistant cabin
(because of job demand, beacon need to slip into seabed with detecting devices, it is therefore desirable to compressive sealed), can increase sealed compartment undoubtedly
Diameter (top, cabin needs two antennas placed side by side), causes volume big, installs inconvenience.
The principle of tellurometer survey localizer beacon method is: beacon is fixed on target-detection unit, and receptor is controlled by user
System.Receptor has 3 (or more) antennas, and the position of these antenna is fixed, and receptor can be believed by wherein certain root sky alignment
Mark sends radio wave, and beacon sends one section of radio wave to receptor after receiving radio wave the most again, and then receptor is caught
Catching this section of radio wave, receptor can detect that it has just sent radio wave and the time difference again received between radio wave,
Thus can calculate the distance between this root antenna and beacon.By that analogy, it is possible to obtain the distance between every antenna and beacon,
So just can resolve the azimuth-range between receptor and beacon by mathematical method.
The method requires that beacon is constantly in holding state, waits the signal sent from receptor, and power consumption is big, transports for a long time
Row there may be chance failure and occurs, poor stability.
Utility model content
Technical problem to be solved in the utility model is just to provide that a kind of power consumption is little, the phase place localizer beacon that stability is strong
System.
This utility model adopts the following technical scheme that
A kind of phase place location beacon system, it thes improvement is that: described system includes beacon and receptor；Beacon bag
Include the radio station being sent out radio wave signal, control the controller of radio station work, the power supply pipe powered for controller and radio station
Reason module, this outer controller can also control whether power management module is that radio station powers on；Receptor includes the sky of more than three
Line, for sending the signal source of frequency-fixed signal S, mixes for radio wave signal and the frequency-fixed signal S receiving antenna
The frequency mixer that frequency processes, for the signal after Frequency mixing processing is filtered the low pass filter processed, and is used for measuring
The measurement chip of time difference.
Further, described antenna is four, receptor be each side symmetrical arranged two.
Further, described receptor also includes the amplification that the signal after filtered process is amplified Shape correction
Reshaper.
The beneficial effects of the utility model are:
Phase place location beacon system disclosed in the utility model, it is only necessary to use radio station, it is not necessary to GPS module, and
Radio station is also to open a bit of time (less than 0.1S) the most in use, sends a bit of radio wave signal, and power consumption is little；Only need
Want radio station, it is not necessary to GPS module, the most only need an antenna, volume can be reduced.Reduce beacon power consumption and body greatly
Long-pending, make beacon simplify, stand-by time is longer, works more stable, because beacon needs to work under unmanned state for a long time, it
Function is the simplest, the longer the better for stand-by time.
Beacon need not the most standby, but takes the used time to power on, and (all peripheral hardwares are not the most disconnected for used time entrance sleep state
Electricity, only core space sub-fraction powers on), wait that working time next time turns on the power management module the most again and powers on to radio station；
Beacon is only used as transmission source, does not receive extraneous any signal, therefore can ensure that its stability.
