An underwater sensor and a positioning system

Abstract

The invention provides an underwater sensor and a positioning system. The underwater sensor comprises a ReRAM and a controller, and the controller is connected with the ReRAM; wherein the ReRAM comprises a memory module and an Euclidean measurement module; the memory module is used for caching input data; the Euclidean measurement module comprises a plurality of parallel measurement modules, and each parallel measurement module comprises an addition calculation module, an extraction calculation module and a plurality of parallel calculation modules; the parallel computing module comprises a first subtraction array and a first multiplication array; the parallel computing module is used for performing parallel computing on each addend in the Euclidean metric formula; and the addition calculation module is used for completing a summation process of operation results of all units of the parallel calculation module and taking the results as input data of the evolution calculation 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...

(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.
