In aquaculture, water quality is influenced by excessive feeding, a high breeding density, the species composition and the distribution of algae species. Traditional buoys can only collect water quality data at a fixed depth, and it is impossible to measure the water quality at different depths in the water column. Sea waves are common in the open ocean and influence data acquisition systems via wave forces, which affect the accuracy of data collection. Considering the above problems, a data acquisition control system with automatic lifting is designed. The underwater acquisition system collects water quality data and sends the data to a microcontroller. The microcontroller sends a displacement control signal to a PLC according to the processed data. The PLC automatically develops the corresponding acceleration and deceleration operating curves according to the displacement. A fuzzy PID self-tuning control method is used to accurately control the speed and steering of the stepping motor, and an IIR digital filter is designed to reduce the interference from sea waves. The simulation results show that the stepping motor responds quickly, the speed of the stepping motor is stable, and the data acquisition time is reduced based on the proposed algorithm. Moreover, wave interference is largely mitigated, and the system is generally stable.

“…The data acquisition module mainly includes signal conditioning. The road switch and A/D conversion are involved in the acquisition and conversion of multiparameter analog data [12]. The signal transmission module mainly relies on a communication cable to send the water quality data to the control system.…”

“…The generation of on-board information such as the position of the vessel and environmental data of interest (sea water characteristics and weather conditions) has made use of the Oceanographic Data Acquisition System deployed onboard by the UTM [3]. Essentially it converts all communications between systems that provide data with local communication protocols such as RS232 and then broadcasts this information on the Local Area Network (LAN) in the form of ASCII telegrams transmitted via UDP protocol [4].…”

Abstract-This work describes the development of a monitoring system for vessels from the Marine Technology Unit (UTM) of the Spanish Research Council (CSIC) and draws on the graph capabilities and the potential access to remote data that is offered by Google Earth and the new satellite data transmission capabilities installed on-board. Performance analysis is carried out at several critical points of the system, in terms of data processing and networking, showing that, with minor variations in implementation, this system can be adopted to monitor a greater number of mobile units while at the same time remain sufficiently flexible to be used as a didactic teaching tool for schools and universities. This development is a product of a more ambitious acquisition project that deals with the modeling and acquisition of oceanographic data led by a working group at the UTM and the Universitat Politècnica de Catalunya.

“…It is designed following a Service Oriented Architecture (SOA) with a multilayer service schema in order to be easily expandable to new required data services [7]. It is fully operational and it has been implemented on top of the Java library and data model build in two previous technological research projects: The Virtual Distributed Lab for Oceanographic Data Processing and Monitoring (LabVir) and the Interoperability in Environmental and Marine Sensor Networks (INTIMAS), both funded by the Spanish government [6].…”

-This paper describes the design and the development of a new real time data acquisition system which focuses on oceanographic research. The system has been implemented in several Spanish oceanographic platforms (vessels and land-sites) using very reliable MESH network that can still operate when one node breaks down or a connection goes bad. Service Oriented Architecture allows expandable access to real time and historical data. This system is applicable to any network of instrumentation where an integrated management of data and a wide range of access procedures are needed. We can frame these data acquisition system in a satellite communications environment both VSAT (C band) and TNX75 (X band). The target domain off these projects is to provide long-range data and optimize satellite communications resources. The challenging issue is to achieve cross-platform data-generating infrastructure, which in an optimized use of system resources and provide real time information to the user without depending on the location in which to generate or produce them. The project is focused mainly in relation to the acquisition of data, such as an integrated system of generation of data with a multilayer structure for accessing data consulting services, all using communications via satellite. To this day, we fully integrated platform and running, and we are expanding the services and optimizing the end-user interfaces with these new services. The eyelet of this document is to provide global technical community the current status in Spain, in regard to oceanographic data generation and exploitation of the same by the scientific community, from both the oceanographic vessels located anywhere of the world from locations ashore.
