Microprocessor-based Turbomachinery Management Systems

Digital control methodologies similar to the Elliott Digital System program evolved from successful and proven reliable high-speed air compressor management and control approaches. 

Before diseussing the turbomaehinery management attributes of digital systems, it is helpful to review the hardware, software, and MACS PACK eomponents. 

Elliott has also developed the Laser Sentry System, whieh is a monitoring deviee used in FCC applieations. The system deteets solid partieles entrained in gas streams on a eontinuous and real-time basis. It is a good example of a deviee that ean be easily integrated into the EDS to provide enhaneed data management. 

Onee the information is entered into EDS it is available for display, eommunieation, status, manipulation, and arehiving. A eolor graphie operator interfaee (VGA high resolution monitor with integral keyboard) is provided. The standard operator interfaee with eombined sereen and keyboard was seleeted based on loeation flexibility, ease of use, and eompatibility with future EDS paekages. A baekup two-line display/keyboard is provided should the main operator interfaee(s) or the Administrative CPU fail. 

The software employed for the eritieal elements (memory, alarming, tripping, and eommunieating with the host eomputer) uses a real-time operating system and resides in the main CPU. The administrative CPU employs multitasking software that performs important tasks sueh as modem eommunieation, trending, and arehiving.
