Online ocean water quality data acquisition system and method suitable for survey ship operation

Abstract

The invention discloses an online marine water quality data acquisition system and method suitable for survey ship operation, and the system comprises a plurality of unmanned ship data acquisition terminals which employ sensors to acquire marine hydrology and water quality data, process the acquired data through a microprocessor, and automatically transmit the processed data to a corresponding survey ship numerical control center in real time, an instruction from a survey ship numerical control center is received to realize control of data acquired by the acquisition terminal; the survey shipnumerical control center is used for acquiring the marine hydrology and water quality data acquired by the data acquisition terminal through the gateway module, forwarding the acquired data to the data and processing center for processing and storage, synchronizing the data to the shore-based data center through a network, and displaying related data information through the observation terminal; the data acquisition terminal is controlled; and the shore-based data center is used for receiving the data transmitted by the survey ship numerical control center by utilizing a network and carrying out centralized management and comprehensive application on the data.

Description

technical field [0001] The invention relates to the technical field of marine water quality monitoring, in particular to an online marine water quality data collection system and method suitable for survey ship operations. Background technique [0002] The ocean is the cradle of human life, and because of its rich natural resources, it has become the focus of development and research in various countries. The purpose of studying the ocean is to understand the ocean and develop and utilize the ocean. Marine survey is the basic means for people to understand, explore and utilize the ocean. Among them, the water quality survey related to the marine ecological environment is the primary prerequisite for the planning, supervision and management of marine environmental protection and the prevention and control of marine pollution. In the era of rapid technological development, innovation and comprehensive utilization of high-tech to conduct scientific, low-cost, and efficient oce...

Problems solved by technology

[0004] The existing technology has the following defects and deficiencies: 1) The remote sensing observation method has low temporal and spatial resolution, often low observation accuracy, and the observation is easily affected by the weather, so it is not suitable for small-scale and rapidly changing sea area surveys and research; 2) On-site survey method, although it can be measured directly, it still needs manual data transfer processing in the later stage. The observation data displayed by some equipment needs to be recorded again by the operator, and the observation data stored by some equipment needs to be transferred in the later stage; 3) The observation data of the field investigation method presents the characteristics of single point and fragmentation, and it is difficult to analyze it in time, so as to grasp and understand the environmental conditions reflected by it from an overall or regional perspective, and it is not convenient for investigators to conduct field investigations based on Adjust the survey plan for the special water quality environment reflected by the data; 4) The data of the field survey method is difficult to share, and it is inconvenient for multiple ships to work together
