The Design Of Data Storage Extension In Vector Sensor Array Target Detection System

With the continuous development of underwater acoustic technology and electronic technology, the data storage system in underwater acoustic technology research and development of underwater acoustic equipment plays an increasingly important role, and the acoustic equipment constantly updating puts forward higher requirements to the volume of a storage medium, capacity and speed of data storage and storage system's practicality, stablity,and cost aspects. This paper designs the data storage extension of vector sensor array target detection system, the goal is to send, receive and store network data.This design uses MityARM-1808 as the control chip and then builds embedded Linux operating system, uses USB2.0 transfer gigabit network adapter to send and receive network data and implements the SATA hard disk data storage.This paper completes the design and debugging of the data storage extension of vector array target detection system. Firstly according to the requirements, the paper designs and completes the MityARM-1808 as the core of data storage engine hardware circuit, including schematic design and PCB production. Hardware circuit includes core board, network communication module, serial peripheral interface circuit module, SATA hard disk storage module, SD card storage module and power module. Then the paper carries on the debugging of each hardware module, writes the network data transceiver and SATA hard disk storage program and realizes the data receiving and forwarding via TCP network and hard disk storage. Finally this design tests and verifies the performance, including the network transmission performance and hard disk storage performance, and proves the feasibility and rationality of the design.
