Instrumentation ViewPoint. Autumn 2005 53 3. Installation Proces In august, 2005, we proced to the installation of 5 SCRIED units in the laboratories as follow: LABORATORIO EQUIPOS ELECTRONICOS de Popa Temperatura and Humidity MAC: 00-20-4A-84-35-C6 IP: 192.168.1.91 1. Introduction The objective of the present paper is to present the experience about the integration of a group of hardware/software technologies that are applied successfully in networks and systems based on TCP-IP protocol and can be used to implement distributed and data acquisition systems. In this case is presented the installation in the Oceanographic Vessel Hesperides different data acquisition and instrumentation systems to monitor and datalogging using standard communication networks. We present a TCP and UDP Humidity and Temperature server designed by our team in the framework of LabVir project. LabVir project is devoted to implement distributed measurements in marine technologies. 2. Developped work In order to monitoring the humidity and temperature values in the laboratories of the Spanish Oceanographic vessel Hesperides and to monitor the Capstan Load information from the Load Cell we have designed a device server using TCP and UDP protocols. This custom electronic hardware design called SCRIED is based on a lost cost microcontroller which is a PIC16F870 to perform analog to digital conversion of the signal coming from the temperature and humidity sensor (HT-923) and the load cell amplifier that are signals from 4 to 20mA. When the acquisition is performed, the microcontroller sends the temperature and humidity information through the serial port to a Lantronix firm XPORT embedded system. Data is collected by XPORT from the serial port and transmitted through the Ethernet port whose connection is implemented using LabVIEW and its libraries. Figure 1 shows the system esqueme where take place: -acquisition from the sensors. -data transmission using a 4-20mA loop from the sensors to the SCRIED electronic system (figure 2). -data processed to send information over the network. -Datalogging and monitoring using LabVIEW applications.
