DESIGN OF A PIC BASED DATA ACQUISITION SYSTEM FOR PROCESS AND CONDITION MONITORING

摘要

This paper describes the design of a data acquisition system, based upon a Microchip PIC microcontroller, that is being developed for condition and process monitoring. It presents the considerations made in the development of hardware and software to allow the deployment of a monitoring system based upon the Petri-net concept. The methods by which the data collected by the system can reach a centralised database are described. In doing so consideration is given to the available connectivity options for the micro-controller based monitoring system used. The benefits and limitations of such a micro-controller based system are discussed using some initial results obtained by the experiment.
