Brief description:
Fig. 1 is the method frame figure improving boat trip safety
Specific embodiment
The application passes through ultrasonic transmitter (1), and ultrasonic receiver (2) and Beidou satellite navigation system (3) determine ship surrounding waters ground
Lower situation, to improve the safety of ship region navigation nearby.
The prepositioned seabed seabed position not far in departure from port mouth of this ultrasonic transmitter (1), is especially located in the areas adjacent of navigation channel process.
There is a memorizer (4), this memorizer (4) can regularly be communicated with ground control system (5), will in this ultrasonic transmitter (1)
The geography information of new near zone, is transferred to ultrasonic transmitter (1) including sea-floor relief, ocean current situation by ground control system (5)
In memorizer (4)；
Ultrasonic transmitter (1) is configured to be fixed on seabed position s1, fixed frequency f can be sent every a set time1Ultrasound wave, no
The fixed frequency that sends with the ultrasonic transmitter (1) of position simultaneously differs, that is, be fixed on seabed position sn, then can send every a set time
One fixed frequency fnUltrasound wave.By the ultrasound wave of different frequency, the discriminating of the ultrasonic transmitter to diverse location can be accomplished.Concrete steps
For:
1. ultrasonic receiver (2) is fixed on ship, and it is configured to receive the letter of the fixed frequency that ultrasonic transmitter (1) is launched
Number.When receiving fixed frequency f that certain ultrasonic transmitter (1) sendsnUltrasonic signal when, first pass through fixed frequency f prestoringn
With the corresponding relation of seabed position sn, thus finding the particular location of its ultrasonic transmitter (1)；2. pass through big-dipper satellite alignment system (3)
Complete the time synchronized of ultrasonic receiver (2) and ultrasonic transmitter (1)；3. the used time t according to received ultrasonic signal, and ultrasound wave
Spread speed v, calculates the seabed position sn of synchronization diverse location and the distant relationships of ship；4. sea bed is received by ground control system
Up-to-date seabed map near the sn of position and up-to-date ocean current situation；5. pass through up-to-date seabed map and the up-to-date ocean current situation rule obtaining
Mark optimal safety to approach navigation route.
Ultrasonic receiver is not provided with some ships, for the safety of these boat trip, can be protected by as above step: right
In the above-mentioned ship being provided with ultrasonic receiver, generate the sea-floor relief near this ship and ocean current situation information, accumulate the form of chart,
And ground control system is transmitted this information to by this ship, this chart can be sent to and be fitted without ultrasonic probe, ultrasonic receiver by ground control system
Ship, for its navigate by water reference.
In addition, whether sub-sea location sn comparing nearest fixed frequency fn receiving between ship and ship is identical, if identical, ship
And as only between pass through the mutual alarm of photoelectricity alert methods.
Using the method, being capable of quick localizing emission source using underwater ultrasound wave technology.In addition pass through the renewable surrounding waters of Beidou satellite navigation system
Up-to-date sea-floor relief and ocean current situation, thus providing planning for boat trip, ensure boat trip safety.
