An underwater sensor and positioning system

Abstract

The disclosure provides an underwater sensor and a positioning system. Wherein, an underwater sensor includes a ReRAM and a controller, and the controller is connected to the ReRAM; the ReRAM includes a memory module and a Euclid measurement module; the memory module is used for buffering input data; the Euclid The Reed measurement module includes several parallel measurement modules, each parallel measurement module includes an addition calculation module, a square root calculation module and several parallel calculation modules; the parallel calculation module includes a first subtraction array and a first multiplication array; The parallel calculation module is used for parallel calculation of each addend in the Euclidean metric formula; the addition calculation module is used to complete the summation process of the operation results of each unit of the parallel calculation module, and use the result as the square root calculation Input data for the module.

Description

technical field [0001] The disclosure belongs to the field of underwater network communication, and in particular relates to an underwater sensor and a positioning system. Background technique [0002] The statements in this section merely provide background information related to the present disclosure and do not necessarily constitute prior art. [0003] With the development of science and technology, artificial intelligence has penetrated into various fields of social ecology. Prevention and control of marine ecological pollution, protection of the marine environment, and development of marine economy are one of the current national development strategies. Smart ocean has become an important development direction for maintaining the marine environment and monitoring the state of the ocean at this stage. In order to better monitor marine environmental indicators (such as algae distribution, etc.), the design and application of a smart ocean real-time monitoring platform b...

Problems solved by technology

(2) Due to the large number of nodes, it is often necessary for a node to calculate the distance between itself and multiple other nodes at the same time when determining the distance between them. However, the traditional serial execution method cannot guarantee the real-time performance of the calculation, and the parallelism is insufficient.

It can be seen that in the process of underwater positioning, the Euclidean distance is frequently calculated, and the calculation speed and real-time requirements are high, and the power consumption is relatively large.
