Description
Summary:A model for distributed signal acquisition and processing has been designed and implemented. The model is based on a LAN client-server structure: it allows signal acquisition on a dedicated server and acquired samples distribution to different client workstations for signal representation and/or processing. The communication between server and clients is based on TCP/IP protocol. A set of specific commands allows the client to get the server acquisition configuration and to request/receive signal samples. In order to facilitate the development of client own system for signal analysis a library of Java functions (or classes) was created including the basis of biosignal processing and display; these classes have to be included by the developer into the user specific program for signal acquisition and elaboration. The system is under test in the research LAN of our Institute. It consists of one PC-server with an AID converter board and one client workstation for displaying and processing cardiovascular and respiratory signals obtained from patients studied with autonomic testing.
