Wireless Data Transfer System for Oil Drawing Plants

The present work describes the design and building of a data transmission system for Collector Centres monitoring and automation in an Oil Drawing Enterprise in Cuba (EPEP). Packet-radio modems were used, working in the VHF bands at 1200 and 9600 bits per second, resulting in an economic solution. This data transmission system is a wider and modem version of the previously developed at 1994 by the authors. The system goal is automatic transfer of files and data collected by instruments, from several oil drawing centres, to the computer network located in the headquarters building. This task is done without interfering with other applications normally executing in these plants. The new system runs in multitasking environments such as Windows95 and WindowsNT.
