Installation ProcesIn august, 2005, we proced to the installation of5 SCRIED units in the laboratories as follow:LABORATORIO EQUIPOS ELECTRONICOS dePopaTemperatura and HumidityMAC: 00-20-4A-84-35-C6IP: 192.168.1.911. IntroductionThe objective of the present paper is to presentthe experience about the integration of a groupof hardware/software technologies that areapplied successfully in networks and systemsbased on TCP-IP protocol and can be used toimplement distributed and data acquisitionsystems. In this case is presented the installationin the Oceanographic Vessel Hesperidesdifferent data acquisition and instrumentationsystems to monitor and datalogging usingstandard communication networks. We presenta TCP and UDP Humidity and Temperatureserver designed by our team in the frameworkof LabVir project. LabVir project is devoted toimplement distributed measurements in marinetechnologies.2. Developped workIn order to monitoring the humidity andtemperature values in the laboratories of theSpanish Oceanographic vessel Hesperides andto monitor the Capstan Load information fromthe Load Cell we have designed a device serverusing TCP and UDP protocols. This customelectronic hardware design called SCRIED isbased on a lost cost microcontroller which is aPIC16F870 to perform analog to digitalconversion of the signal coming from thetemperature and humidity sensor (HT-923)  andthe load cell amplifier that are signals from 4 to20mA.  When the acquisition is performed, themicrocontroller sends the temperature andhumidity information through the serial port toa Lantronix firm XPORT embedded system.Data is collected by XPORT from the serial portand transmitted through the Ethernet port whoseconnection is implemented using LabVIEW andits libraries. Figure 1 shows the system esquemewhere take place:-acquisition  from the sensors.-data transmission using a 4-20mA loop fromthe sensors to the SCRIED electronic system(figure 2).-data processed to send information over thenetwork.-Datalogging and monitoring using LabVIEWapplications.Marine Information over the NetworkJ. del Río (1), J.Sorribes (2), E.Trullols (1),  A.

Autumn 200554The datalogging and monitoring proces is carriedout from different software applicattionsprogrammed in LabVIEW as we can see infigure 3. This application allow the user to selectthe SCRIED IP address and the protocol used.Then the information is represented by the softfront panels windows in figure 5.Figure 3: Photos about two installed SCRIEDsin the Hesperides vessel a) Temperature &Humidity monitoring. b) Capstan load from LoadCell amplifier monitoring and datalogging.Figure 4:  SCRIED IP and protocol selectionLABORATORIO CCTemperatura and HumidityMAC: 00-20-4A-84-35-EAIP: 192.168.1.92LABORATORIO DE GRAVIMETRIATemperatura and Humidity.MAC: 00-20-4A-84-35-C1IP: 192.168.1.93LABORATORIO DE SISMICATemperatura and HumidityMAC: 00-20-4A-84-35-E0IP: 192.168.1.94LABORATORIO EQUIPOS ELECTRONICOSde ProaCapsta LoadMAC: 00-20-4A-84-35-C5IP: 192.168.1.954. ConclusionsThis paper has presented the installation processof a custom electronic design in order to monitordifferent parameter over the ethernet networkof the oceanographic vessel Hesperides. Thisexperience can be expanded to other marineparameters where a distributed monitoring ordatalogging is needed.5.
