Embodiment Construction

[0011] The present invention adopts nylon cable, about 5 meters long. The sinker 5 is connected with the release device 4 with a nylon rope or a steel wire rope, and its length depends on the depth of the sea area and the working depth. The synchronous ranging device 13 utilizes the hydrophone 7 as a synchronous sound receiver, the microprocessor controller 14 controls the work of other parts, and provides parameter information at the same time, which is recorded by the recorder, and the remote control receiving and answering device 15 is controlled by the remote control / answer Transducer 3 is used as remote control command receiver and response sound transmitter. Such as image 3 As shown, it is in the watch state 17 at the beginning, and it first judges whether it receives the "remote measurement" command 18. If change over to automatic recording state 19, if not judge whether to receive " remote control recording " instruction and arrive pre-programmed action time 22 agai...

Abstract

A recoverable subsurface buoy recorder for underwater noise is a system which has both functions of remote control and automatic control as it is composed of subsurface buoy, releasing device, and anchoring block. The system can be on duty under water depth of 300 m for long-term and can record underwater noise at range of 1 herts to 100 kiloherts on real time according to preprogram command or abovewater remote command at any time.

Description

technical field [0001] The invention relates to an underwater noise measurement device, in particular to a marine environment noise measurement system. Background technique [0002] The underwater noise measurement of the prior art, one adopts the method of suspension or towing of the working boat or surface buoy, and the other adopts the method of the shore station. In the former method, the measurement hydrophone is directly hoisted into the water from the working boat, or is towed behind the boat through a shock absorbing device, and the signal is transmitted to the working boat through a cable for recording and analysis, and some use surface buoys instead of the working boat to measure water The earphone is hung under the buoy on the water surface, and the signal is transmitted to the buoy on the water surface through the cable, and then sent to the working ship or the shore experiment station by radio wave for recording and analysis. The above methods have the advantag...
