FIG. 1 shows a block diagram of an underwater sensor according to an embodiment of the present invention, in which 1 is a capsule, and this capsule 1 is connected to a ship 3 with a wire 2 as shown in FIG. It is submerged in water 4.
Reference numeral 5 denotes an ultrasonic transducer for water depth measurement attached to the surface of the capsule 1. When an output signal is sent from the transceiver 6 to the ultrasonic transducer 5 for water depth measurement, as shown in FIG. Ultrasonic transducer 5 for water depth measurement
Ultrasonic waves are emitted from the water surface 4' to the water surface 4', and the reflected waves are received by the ultrasonic transducer 5 for water depth measurement, converted into electrical signals, and detected by the transceiver 6.
Water depth can be measured based on the time taken for the ultrasonic waves to travel back and forth between the ultrasonic wave and the water surface 4'. 7 and 8 are a transmitting vibrator and a receiving vibrator for temperature measurement, and capsule 1
When an output signal is sent from the transmitter 9 to the transmitting transducer 7, the transmitting transducer 7 emits an ultrasonic wave. This ultrasonic wave is received by the receiving transducer 8, converted into an electrical signal, and detected by the receiver 10. That is, temperature changes are measured from changes in the transit time of the ultrasonic waves between the transmitting transducer 7 and the receiving transducer 8. 11 is a compass, and a water flow direction detection circuit 12 detects the direction of the water flow based on the direction of the capsule 1 from the direction of the compass 11. 13
is a CPU, which sequentially drives the water depth measurement transmitter/receiver 6, the temperature measurement transmitter 9 and receiver 10, and the water flow direction detection circuit 12, and stores the detected data in the memory 14. Reference numeral 15 denotes a power source such as a battery, and this power source drives the circuits of various parts within the capsule 1. 16 is a terminal section provided near the surface of the capsule 1, which supplies power to the power source 15;
Sending and receiving data to and from the CPU 13 and memory 1
The capsule 1 is provided for transmitting and receiving data stored in the capsule 4, and is sealed with a lid when the capsule 1 is submerged in water. Reference numeral 17 denotes a terminal portion that is connected to the terminal portion 16 provided on the capsule 1 when the capsule 1 is lifted out of the water, and a display charging circuit 18 is connected to the terminal portion 17. This display charging circuit 1
8 is equipped with a power supply circuit connected to an external power supply, and when the main switch is turned on, the access circuit automatically sets the memory addresses in sequence, thereby driving the CPU 13 of capsule 1 and accessing the memory of capsule 1. 14, the read data is read by a reading circuit, stored in the memory, and the read data is automatically displayed on a display device. It also includes a charging circuit that automatically charges the capsule's power source 15 when the main switch is turned on.

In the underwater sensor of this embodiment configured as described above, when the transmitter/receiver 6 is driven by the CPU 13, ultrasonic waves are emitted from the depth ultrasonic transducer 5 toward the water surface 4'. This reflected wave from the water surface 4' is received again by the water depth ultrasonic transducer 5, converted into an electrical signal, and received by the transceiver 6, thereby transmitting the ultrasonic waves between the water surface 4' and the capsule 1. Changes in water depth are measured by changes in travel time. Next, when the transmitter 9 and receiver 10 are driven and an electric signal is emitted from the transmitter 9, an ultrasonic wave is emitted from the transmitting transducer 7, and this ultrasonic wave is received by the receiving transducer 8. By converting the ultrasonic wave into an electrical signal and receiving it at the receiver 10, a temperature change can be detected based on a change in the transit time of the ultrasonic wave between the transmitting transducer 7 and the receiving transducer 8. In addition, the transmitting transducer 7 and the receiving transducer 8
If exposed on the surface of the capsule 1 and affected by tidal currents, the transmitting transducer 7 and the receiving transducer 8 may be mounted in a cylinder or the like into which water can freely enter.
Furthermore, when the water flow direction detection circuit 12 is driven next,
Since the compass 11 is displaced depending on the direction in which the capsule 1 is facing, by detecting this displacement, the direction in which the capsule 1 is facing, that is, the direction of the current can be detected.

All of the data detected in this way is stored in the memory 14 in correspondence with time, water depth, etc. After a certain period of time, Capsule 1 will be pulled up to the ship.

This lifted capsule 1 is connected to the terminal section 16 and the terminal section 17 of the reading display charging circuit 18, and when the reading display charging circuit 18 is driven, the CPU 13 of the capsule 1 is accessed and the memory 1
4 is read by a reading circuit and stored in the memory of the reading display charging circuit 18. During this time, the power supply inside the capsule 1 is charged by the charging circuit.

In this way, in the circuit of this embodiment, data is read from the memory 14 in the capsule 1 on board the ship, so there is no contact failure due to corrosion of the terminals, and there is no need to provide a signal line in the wire.

In the above-mentioned embodiment, an ultrasonic transducer was used to measure the water depth, but a bellows may be used instead of the ultrasonic transducer, and the water depth may be measured based on the pressure change of the bellows.

Effects As is clear from the above explanation, with this invention, data can be obtained simply by submerging the capsule in water, so there is no need to attach a signal line as a wire, and data reading can be done by simply bringing the capsule onto the ship. Since the lid of the terminal part is opened and the connection is made, the entire capsule can be sealed, and it is possible to eliminate poor contact due to corrosion of the connecting part when connecting wires as in the conventional example.
