Embodiment Construction

[0017] The present invention will be described in detail below with reference to the accompanying drawings and examples.

[0018] This embodiment provides a low-power underwater data recorder system for deep-sea environments. The system can collect underwater acoustic signals and store them in an internal memory card, which is convenient for use in deep-sea environments; and the system functions Low power consumption, able to work independently underwater for a long time.

[0019] The composition of the low-power underwater data logger system is as follows: figure 1 As shown, it includes an underwater acoustic signal acquisition module, a preamplifier, a filter, a pressure sensor, a controller, a storage module and a power supply, and the peripheral device is a host computer. Among them, the controller adopts MSP430 controller MSP430FG4618, and the storage module adopts MIC-SD card.

[0020] The underwater acoustic signal collection module is used to collect underwater acous...

Abstract

The invention discloses an underwater data recorder system low in power consumption and belongs to the technical field of underwater sound communication. The data recorder system can collect underwater sound signals and store the signals into a storage module in the data recorder system, can be used in the deep sea environment conveniently and is low in power consumption. The data recorder system specifically comprises an underwater sound signal collecting module, a pre-amplifier, a filter, a pressure sensor, an instrument amplifier, a controller, the storage module and a power source. The underwater sound signal collecting module is used for collecting the underwater sound signals, the collected underwater sound signals are amplified and filtered, then the controller carries out A/D conversion on the underwater sound signals, and the underwater sound signals are written into the storage module through a set format. The pressure sensor is used for collecting pressure data of the working environment of a data recorder so as to obtain the actual depth of underwater working of the data recorder. The system reduces the power consumption of the data recorder by managing the work mode and the work procedure of the data recorder with the lower power consumption, and therefore the data recorder can work independently underwater for a long time.

Description

technical field [0001] The invention relates to a data recorder system, in particular to a low-power underwater data recorder, which belongs to the technical field of underwater acoustic communication. Background technique [0002] With the rapid development of marine development in various countries in the world, the demand for marine hydrological detection is also becoming more and more extensive. The development and application of data loggers are gradually developed under the impetus of this continuously improving technical demand. At present, most of the existing intelligent data recorders are plug-in data recorders, and the collected underwater acoustic signals need to be transmitted to the receiver through the cable for storage or processing. However, in order to obtain the underwater acoustic array signal, the data recorder needs to be placed in the deep sea environment, and the traditional way of transmitting the underwater acoustic signal by cable is inconvenient a...
