A distributed system to automate labor-intensive industries andbuilding supervision

摘要

The present paper describes a distributed system, which purpose isto control and manage the operation of different electrical andelectronic systems and other equipment. The system was designed to beinstalled over already in place nonautomated devices, delivering allrelevant data either to machine operators or managers; different formatsare used in these messages, leading to a hierarchical control andsupervision. The system was developed on industry demand, primarily toachieve building supervision and control. It allows real time control ofdifferent devices and systems as a simple intrusion detector to an,already in use, industrial network. Several intelligent controllers weredeveloped and are presented. The system can have different topologiesand interconnect, through gateways, to already installed networks. Thedifferent level algorithms used either at the PC or the controllers aredescribed and discussed. We also present the work we are carrying out toallow the interconnection of the system to a WAN, allowing an authorizeduser to supervise the system
