Problems solved by technology

If the communication inside and outside the cabin is realized by wired connection through perforation in the bulkhead, it will inevitably affect the integrity of the cabin. In addition, the control network such as metal partitions and power pipelines of ship machinery and equipment has high requirements for airtightness and pressure resistance. , so the method of sending distress signals by means of data transmission in the form of bulkhead wiring is flawed

Embodiment Construction

[0016] In conjunction with the accompanying drawings and examples of implementation, the technical solutions adopted by the present invention are further illustrated:

[0017] Such as figure 1 As shown, an emergency system for shipwreck is based on maritime satellite network or cellular network communication. The emergency system includes the interior and exterior of the ship cabin, wherein the button switch, signal drive circuit and transmitting transducer are located inside the cabin. , and the transmitting transducer is adhered inside the bulkhead with couplant; the receiving transducer, signal processing circuit, and maritime satellite telephone equipment are located outside the cabin, and the maritime satellite telephone equipment is placed in an external non-metal airtight container, and the receiving transducer is used The couplant sticks to the outside of the bulkhead.

[0018] Ships can be equipped with several emergency distress devices, which are scattered and inst...

Abstract

The invention relates to an SOS system for ship wreck and belongs to the field of ultrasonic wave transmission. The SOS system comprises a button switch mounted in a cabin, a signal drive circuit mounted in the cabin, transmitting transducers distributed on the inner wall of the cabin, receiving transducers distributed on the outer wall of the cabin, a signal processing circuit, a marine satellite telephone equipment and coupling agents attached to the inner wall and the outer wall of the cabin, wherein the signal processing circuit and the marine satellite telephone equipment are mounted outside the cabin. The SOS system can overcome the defect that communication quality is reduced due to a skin effect of electromagnetic waves in metal surfaces during traditional wireless communication and can acquire and transmit SOS signals in a metal shielding body under the condition that the completeness of the cabin is not damaged, and accordingly, high-speed and errorless transmission of the SOS signals is realized. The SOS system is simple in structure and low in cost, can transmit the SOS signals in time when a ship wrecks, can also aid in quick positioning of trapped people and facilitates rescuing.

Description

technical field [0001] The invention belongs to the field of ultrasonic transmission, in particular to an ultrasonic transmission system in a metal shielding body. Background technique [0002] In the field of wireless transmission, bulkheads have a shielding effect on radio signals and electromagnetic signals are severely attenuated in bulkheads due to the skin effect. It is difficult to use radio as a transmission signal to achieve high-speed and error-free data transmission and to achieve the effect of calling for help in time. If the communication inside and outside the cabin is realized by wired connection through perforation in the bulkhead, it will inevitably affect the integrity of the cabin. In addition, the control network such as metal partitions and power pipelines of ship machinery and equipment has high requirements for airtightness and pressure resistance. , so the method of sending distress signals by means of data transmission in the form of bulkhead wiring ...
