Auxiliary power unit engine monitoring system
First Claim
1. An engine monitoring and control system, comprising:
- a tested unit having a symbol table with addresses of monitored and controlled parameters of the tested unit;
an external portable personal computer having a memory, a display, and a graphical user interface (GUI) responsive to user commands, for creating customized set of application-specific GUI display pages with icons and text, for displaying received parameter values, and for selecting commands and parameters from the displayed pages;
a monitoring software program including a set of computer-executable program instructions running on the personal computer for retrieving the tested unit parameter values and controlling the tested unit performance; and
a communication link between the tested unit and the personal computer;
wherein the memory receives the symbol table before a test, and the monitoring software program dynamically updates a global arrays table using the addresses from the symbol table during the test, for recalculating necessary data locations, if needed.

Abstract
A method and an engine monitoring and control system is provided. The system includes a tested unit having a symbol table with addresses of monitored and controlled parameters, an external portable personal computer having a memory, a display and a graphical user interface (GUI) responsive to user commands, and a communication link between the tested unit and the personal computer. The GUI is used for creating a customized set of application-specific GUI display pages with icons and text, for displaying received parameter values, and for selecting commands and parameters from the displayed pages. The computer executes a monitoring software program including a set of computer-executable program instructions for retrieving the tested unit parameter values and controlling the tested unit performance. The memory receives the symbol address table before the test, and the monitoring software program dynamically updates the symbol addresses into a global arrays table during the test, by recalculating necessary data locations, if needed. The tested unit is preferably an Auxiliary Power Unit (APU) Electronic Control Unit (ECU). The monitoring software program may be remotely controlled by a remote control system for off-site monitoring and control.
