A mini-computer based interactive signal analysis system

The software structure of an Interactive Signal Analysis System (ISAS) is described in the following sections. The ISAS is embedded in a mini-computer based real-time machinery monitoring network and operates asynchronously with the software performing the monitoring functions. A brief description of the hardware configuration and operational modes for both the monitoring network and the ISAS is presented in the following section. Section III contains an overview of the ISAS requirements and a discussion of the design methodology and choice of programming language. The ISAS software is described in terms of its architecture and file structure, its operating system and network interfaces and the operator-ISAS interaction. In addition, core sizing, timing considerations and error handling are summarized. A discussion regarding the adaptation of ISAS to a stand-alone system is presented in the final section.
