In-situ test system and method oriented to water sound sensor network

Abstract

The invention provides an on-site level radio testing system and a method thereof for the network debugging application of underwater sound sensors, which relate to the field of system tests. A backbone network of the testing system is built on the basis of a radio-frequency radio communication mode and comprises a trunk node (1) which simultaneously supports radio-frequency communication and wired communication, a convergent node (2) and a system administrative center (3) which simultaneously support the radio-frequency communication and the wired communication, and the trunk node (1) provides a wired communication interface for the communication of underwater sound communication testing nodes. The method comprises a uniform transmission mode of automatic framing data packets in different transmission agent, and a TDMA-based two-way transmission method of water surface radio-frequency radio communication. The method can be widely applied to tests in aspects, such as the study of algorism for processing signals of underwater communication systems and the study of the network communication protocol of underwater sound sensors.

Description

technical field [0001] The invention belongs to the technical field of system testing, and in particular relates to a field-level testing system and method for underwater acoustic sensor network debugging applications. Background technique [0002] With the in-depth research on land-based radio frequency wireless sensor networks and the increasing demand for underwater real-time monitoring applications, Underwater Wireless Sensor Networks (UWSN) has become an ocean real-time monitoring technology due to its fast deployment, easy maintenance, and low cost. Its main applications include marine data collection, pollution monitoring, disaster prevention, resource detection, auxiliary navigation, tactical alert, etc. Due to the limitations of wireless communication methods such as radio frequency communication and optical communication in underwater applications, underwater acoustic communication has become the main communication method of underwater wireless sensor networks.
