Design of a Laboratory Data Acquisition System (Time Digitization System).

摘要

A design was developed to show the feasibility of a special microprocessor based data acquisition system called a time digitization system which is to be used during tests of inertial guidance components for Air Force weapon systems. A digital system life cycle was developed to serve as a framework for the design project. Within the life cycle, the following phases were completed: system design, hardware selection/software structure, and circuit layout. A techniqu patterned after the Structured Analysis Design Technique was used to construct a requirements definition model. The requirements model was converted to a system design model by separating hardware and software functions. An Intel 8080A-1 microprocessor was selected to perform the software functions and MSI circuits were selected to perform specialized hardware functions. A software structure using finite state automated theory was created to control the data acquisition process. (Author)
