The Design And Implementation Of Software Platform Of Underwater Distributed Test System

Underwater distributed test is based on wireless sensor networks for positioning anunderwater target measurement technology, which can achieve floating water sensor nodeself-localization, targeting water and other functions. It is widely used in the marine patrol,marine environmental monitoring, water testing and other fields. Due to the particularity ofunderwater environment and the limitation of the large water area monitoring, the monitoring,control and processing operations all rely on the control software system to complete whenthe underwater distributed test system is completed. Therefore, to carry out the underwaterdistributed test system software platform has greet engineering application value andsignificance.In the foundation of analysis of technology related to distributed underwater testing,and the specific requirements of the underwater distributed test systems, Underwaterdistributed test system software platform is designed as a whole, and the system control, dataacquisition and processing, data management, etc. functional modules is demonstrated.In the system control unit design, the master station and test nodes data transmissioncontrol protocol (TCP) is produced. At the same time,the USB interface, power supply, anddata acquisition control process is designed; Data acquisition and processing unit is designedto complete the underwater shock wave signal with variable sampling frequency recovery,noise shock wave signal preprocessing, and test node self-localization algorithm in real time;In the design of the data management function unit, Static parameters and the underwatershock wave signal will be classified storage in which the shock wave signal to be stored in theform of text to facilitate transplantation and processing, and Static parameters will be stored inthe database for queries.Test results show that the design of underwater distributed test system software platformcan meet the requirements of underwater distributed test. It also can complete the waterdistributed test system control, data acquisition and processing, and data management, and other functions.
