Abstract

PURPOSE:To attain the economy of entry in/leave from port by providing plural ultrasonic wave transmission along a pilot guideline of a ship and allowing a reception data analyzer of the ship to analyze the transmitted ultrasonic wave for the purpose of steering control or the like. CONSTITUTION:A ship guiding device guiding a ship 4 in a bay 3 along a quay 2 or the like consists of plural ultrasonic wave transmitters 7(7a-7y) having different frequencies provided on sea bed along the guideline in the bay 3, the reception data analyzer provided to the ship 4, a steering controller and a master controller. The ultrasonic wave transmitters 7 are controlled by a controller on a ground base station 8 at the entry in/leave from port of the ship 4 and ultrasonic waves with different frequencies are transmitted. The ship 4 receives the waves to calculate the relation of position between the ship 4 and each transmission source of the ultrasonic waves, the steering control and the master set control are conducted accordingly thereby attaining guide control of the ship 4 in the bay 3.

Description

[Detailed description of the invention] The present invention relates to a ship guidance system.

When entering or leaving a port, in order for a ship to navigate within a port, it is necessary to fully understand the depth of the water within the port and the topography of the seabed. The ship is guided via a tow line 6 by a plurality of dedicated tug boards 5 in the port 3, which have a thorough understanding of the situation.

Therefore, the coordination between the plurality of tugboats 5 is complicated and takes a lot of time and effort when entering and leaving the port, leading to an increase in costs.

At Tomata, ■ is on land and 2 is on the quay.

The present invention has been proposed in view of the above circumstances, and an object of the present invention is to provide a ship guidance device that reduces costs, time, and labor when ships enter and exit ports.

To this end, the present invention provides a plurality of ultrasonic transmitters arranged at appropriate intervals on the seabed in a port, along the ship's entry/exit taxiway, and adjacent to each other with slightly different frequencies. The present invention is characterized by comprising a steering control device and a main engine control device that sequentially receive the ultrasonic waves transmitted from each of the ultrasonic transmitters and operate via the received data analysis device.

An embodiment of the present invention will be described with reference to the drawings. FIG. 2 is a plan view thereof, and FIG. 3 is a block diagram showing the circuit configuration of the system.

In Figure 2, the same symbols as in Figure 1 indicate the same members as in Figure 1, and 7a, 7b...7y indicate multiple ultrasonic transmitters laid at appropriate intervals on the seabed along the navigation route. 8 is the base, 9 is the ultrasonic receiver, IO is the data processing device, 11 is the steering control device, 12 is the main engine control device, 13 is the steering device, 14 is the main engine, 9 to 14 are the ship 4 It is installed in.

15 is an ultrasonic transmitter control device provided at the ground base 8.

In such a device, first, when the ship 4 enters or leaves the port, the ship 4 requests the ground base 8 to activate the ultrasonic transmitters 73 to 7y installed on the seabed of the port 3.

Upon receiving the request, the ground base 8 grasps the situation in the port 3 and activates the ultrasonic transmitters 73 to 7y.
Ultrasonic waves having different frequencies are emitted from a to 7y, and these ultrasonic waves are received by an ultrasonic receiver 9 equipped on the ship 4, as shown in FIG.

The ultrasonic waves received in this way are sent to the data processing device IO, which calculates the positional relationship between the source of each ultrasonic wave and the ship 4,
Accordingly, the steering control device 11 and the main engine control device 12 operate, and the steering device 13. The main engine 14 is controlled.

In this way, the ultrasonic waves emitted by the ultrasonic transmitter 7 installed on the seabed in the port 3 can guide the ship 4 in the port 3 through the ship automatic control system equipped on the ship 4.

Here, the frequencies of the ultrasonic transmitters 7a to 7y are usually arranged so that they gradually increase or decrease toward the quay 2, so if the ship 4 moves in the direction of gradual increase or decrease, the frequency will naturally increase or decrease toward the quay 2. Reached quay 2.

Note that the departure shout is also the same.

According to such a device, it becomes possible to economically guide ships in a port without using Dada boats.

Note that the ultrasonic transmitter control device 15 provided at the ground base 8 in the above embodiment may be installed inside the ship 4.

In short, according to the present invention, a plurality of ultrasonic transmitters are disposed on the seabed in a port at appropriate intervals along a ship's entry/exit taxiway, and are in contact with each other by 1 μY with slightly different frequencies,
By being equipped with a steering control device and a main engine control device that are installed on a ship entering and leaving a port and sequentially receive the transmitted ultrasonic waves from each of the above-mentioned ultrasonic transmitters and operate via a received data analysis device,
The present invention is extremely useful to industry because it provides a ship guidance system that makes port entry and departure economical.
