ブラウン管上に表示していた。2. Description of the Related Art Conventionally, in this type of display method of a berthing speedometer, ultrasonic waves are emitted from a transmitter / receiver provided underwater on the quay side at regular time intervals, reflected waves from a ship are detected, and sound sounding is performed. By applying the principle of the aircraft, the distance from the quay to the ship was determined, the berthing speed was determined from the change in the determined distance over a certain period of time, and the determined distance and speed were displayed on a CRT as numerical values.

であるという問題がある。In the conventional display method described above, only the current berthing speed and the current distance are displayed as numerical values. Therefore, even if the observer determines that there is danger based on the current data, the large ship is immediately stopped. Can not do. Therefore, it is necessary to always compare the past data with the present data to judge acceleration / deceleration, and there is a problem that the operation is extremely troublesome.

伝達され、船舶ＳＰのコントロールに供される。When the ship SP approaches the quay GG, an ultrasonic wave US is emitted from the berthing speedometer SN provided on the quay GG, and an echo from the marine vessel SP is received to measure a distance from the quay GG. The berthing speed is measured from the change in distance. The measured distance and berthing speed are drawn as a graph on the display. The drawn result is transmitted to the ship SP by radio or optical signal, and used for control of the ship SP.

でわかる。In the case of this embodiment, the following can be understood with reference to the graph of FIG. The speed of the ship SP gradually decreases from 200 m from the quay GG and reaches 100 m from the quay GG. After approaching the quay GG at a constant speed for a while, the speed is increased again, and the vehicle is 80 m from the quay GG.

（図４参照）。When the ship SP is more than 200 m away from the quay GG, the distance and speed are measured and displayed only by the berthing speedometer SN1 (see FIG. 3). However, when the distance is less than 200 m, the two berthing speedometers SN1 and SN2 are operated to enlarge and measure and display the same screen (see FIG. 4). Therefore, in addition to the function of the embodiment of FIG. 1, the parallelism of the ship SP to the quay GG can be understood at a glance. That is, in this embodiment, the ship S
P approaches the quay in parallel from about 90 m (see Fig. 4).
