Abstract
The invention provides a method for improving the sailing safety of a ship and preventing ship collision. The method comprises an ultrasonic transmitter (1) which is placed at a submarine seabed position which is not far from a port in advance and is particularly placed nearby an area through which a navigation channel passes. The ultrasonic transmitter (1) is set to be fixed at a seabed position S1 and transmits ultrasonic waves with a fixed frequency f1 at an interval of a fixed time. The ultrasonic transmitter (1) transmits ultrasonic waves with a different fixed frequency when being fixed at a different position, that is, the ultrasonic transmitter (1) transmits ultrasonic waves with a fixed frequency fn at an interval of a fixed time if the ultrasonic transmitter (1) is fixed at a seabed position Sn. Ultrasonic wave transmitters placed at different positions can be identified through ultrasonic waves with different frequencies. Then a positional relation between the ship and the seabed position Sn is sent to a ground control system, and the control system acquires a ship position relation through calculation and transfers the position relation to the related ship. The method provided by the invention effectively reduces dependency on a satellite navigation system, planning is provided for sailing of the ship via a simple method to prevent collision, and the sailing safety of the ship is ensured.
Description
Technical field:
The application is related to boat trip security fields, prevents navigation collision particularly to improving navigation safety by ultrasound wave and Beidou satellite navigation system
Method.
Prior art:
The navigation safety of ship is always the important step of sea-freight.And the complexity of marine site particularly sea-floor relief, shipping safety is brought with great peace
Full hidden danger.Near harbour, sea-floor relief change is larger by man's activity, and these changes do not reflect in the navigation command system of ship unavoidably in time,
And these sea-floor relief hidden danger cannot be avoided by modes such as traditional prestiges.This just brings potential safety hazard for turn round navigation.Prior art
In be to provide a kind of simple solution ship to navigate with regard to the method how avoiding these potential safety hazards not have, therefore the present patent application purpose
The method of row safety, improves boat trip and particularly approaches safety.In addition, the present invention is directed to the dependence that communicates between ship and ship depending on unduly
The shortcoming of global position system improves, and can greatly simplify positioning step.

Differ, that is, be fixed on seabed position sn, then fixed frequency f can be sent every a set timenUltrasound wave.By the ultrasound wave of different frequency,
The discriminating of the ultrasonic transmitter to diverse location can be accomplished.Then by described ship and snPosition relationship be sent to ground control system, control
System is by being calculated ship position relationship, then this position relationship is passed to relevant ships, concretely comprises the following steps:
The first step, ultrasonic receiver (2) is fixed on ship, and it is configured to receive the fixing frequency that ultrasonic transmitter (1) is launched
The signal of rate.When receiving fixed frequency f that certain ultrasonic transmitter (1) sendsnUltrasonic signal when, first pass through the fixation prestoring

Brief description:
Fig. 1 is to improve the method frame figure that ship props up navigation 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 sea bed not far in departure from port mouth of this ultrasonic transmitter (1)
Position, is especially located in the areas adjacent of navigation channel process.Ultrasonic transmitter (1) is configured to be fixed on seabed position s1, fixing every one
Time can send fixed frequency f1Ultrasound wave, the fixed frequency that the ultrasonic transmitter (1) of diverse location sends simultaneously differs, that is, is fixed on
Seabed position sn, then fixed frequency f can be sent every a set timenUltrasound wave.By the ultrasound wave of different frequency, can accomplish to difference
The discriminating of the ultrasonic transmitter of position.Then by described ship and snPosition relationship be sent to ground control system, control system pass through calculate
To ship position relationship, then this position relationship is passed to relevant ships, concretely comprises the following steps:
1. ultrasonic receiver (2) is fixed on ship, and it is configured to receive the signal of the fixed frequency that ultrasonic transmitter (1) is launched.
When receiving fixed frequency f that certain ultrasonic transmitter (1) sendsnUltrasonic signal when, first pass through fixed frequency f prestoringnWith sea
The corresponding relation of bed position sn, thus find the particular location of its ultrasonic transmitter (1)；2. completed by big-dipper satellite alignment system (3)
Time synchronized with ultrasonic receiver (2) and ultrasonic transmitter (1)；3. the used time t according to received ultrasonic signal, and ultrasound wave passes
Broadcast speed v, calculate the seabed position sn of synchronization diverse location and the far and near distance relation of described ship；4. described far and near distance relation is passed
Deliver to the control system on land.Control system calculates described ship position in real time according to the intrinsic course line of described ship and with the distance of fixed position
Coordinate, and described ship position relationship is passed to relevant ships.The mutual alarm of photoelectricity alert methods can be passed through between described ship and ship.
Using the method, being capable of quick localizing emission source using underwater ultrasound wave technology.In addition passing through should apart from computing formula ancillary terrestrial control system
Not through satellite navigation system, therefore saving positioning step, improved location efficiency, thus providing planning for boat trip, having ensured boat trip
Safety.
