Programmable central intelligence controller and distributed intelligence network for analog/digital control systems

摘要

The present invention involves a programmable microprocessor based controller having the capacity to store multiple operational instruction sets for independently controlling system components. The invention further involves a distributed intelligence network of such programmable controllers having the capability to interface with one another, Host computers, and system control components to provide system- wide automation for simultaneously monitoring and controlling video, audio, and electro-mechanically operated equipment. The programmable controller accepts analog and digital inputs and provides a wide range of user defined control functionality through its analog and digital outputs and its many external connections. The controller can support one and possibly two communication buses, depending upon the application, upon which a plurality of system components may be connected to each. Automatic control system applications include, but are not limited to: concert sound systems, stadium sound systems, theme park automation, video-conferencing, etc. The invention further involves firmware for implementing smooth output limiting, automatic standby, short detection, enhanced ODEP conservation, and interrupt driven reporting.
