Timed sound response release device

Abstract

The invention provides an acoustic response release device capable of timing. The device comprises a Bluetooth module, a real-time clock chip, an attitude sensor, a pressure sensor, a transducer, a pyrotechnic separation circuit and a motor driving circuit, the Bluetooth module is also connected with external preset equipment and is used for presetting communication parameters before the sound response release device enters water to work; the sound response release device can receive an instruction of a mother ship deck operation unit under water and execute the instruction; the instruction comprises completion of state query or remote control release operation; or the sound response release device executes operation according to preset timing; the operation comprises the remote control release operation.

Description

technical field [0001] The invention belongs to the technical field of marine equipment and engineering application, and relates to a timeable acoustic response release device. Background technique [0002] With the increasing intensity of ocean development and the development of science and technology, underwater acoustic communication technology is increasingly being used in offshore oil exploration, seabed surveying and mapping, marine archaeology, submarine optical cable laying and marine scientific research and other fields. At present, the acoustic response release device is the main equipment recovered by the deep-sea observation system, and is widely used in marine engineering, national defense construction and other fields. [0003] The acoustic response release device is mounted with various deep-sea sensors, such as altimeter, temperature-salinity-depth sensor (CTD), turbidimeter, magnetometer, etc. A variety of sensors regularly collect ocean element data, and w...

AI Technical Summary

Problems solved by technology

[0004] 1. Acoustic response release devices often require initial parameter setting before launching, but the acoustic response release devices in the prior art often require wired connections to achieve communication and parameter setting, and the setting process is very troublesome;

[0005] 2. When the acoustic response release device controls the release, it is realized by remote control in the prior art, and the release cannot be completed independently through pre-set timing;

[0006] 3. When the acoustic response release device is controlled to release, it is often released through the release mechanism. If the release fails in this way, the acoustic response release device may not be recovered smoothly, and more release methods need to be found
