Powerful Data Acquisition & Control Software for Powertrain Testing

The iTest system is the central control system in a modern Powertrain test cell. In this function it executes a predefined test schedule by coordinating the dynamometer and throttle systems, along with data acquisition from sensors on the test article or in-cell instruments. iTest achieves this level of functionality through an intuitive configuration editor and user-friendly operator GUI, while employing international standards for connectivity to the test cell instruments. The operator can select from a library of test cycles based on testing standards from North American, European or Asian governing organizations.

Features

• User-friendly interface
• Flexible data acquisition and control setup
• Powerful display builder and configuration utilities
• Easy and flexible test building
• Graphical display of test data
• Open architecture for I/O hardware integration
• Interface to common measurement instruments (emissions bench, fuel meter, etc.)

iTest GUI

The Automation Console software provides a powerful graphical user interface (GUI) that runs in a Windows environment. The GUI provides access to the screen definition tools both in the test building environment and during run time.

• User friendly interface
• Powerful display builder in both development and runtime modules
• Graphical display of test data
• Push buttons and slider controls for manual operation
• Error and message windows

Test Manager

The Test Manager provides a powerful environment for developing test configurations that will guide the test during runtime. In designing a test, development engineers have a variety of options, from simply selecting from a list of pre-defined modules corresponding to the in-cell instruments, to writing script-driven routines.

A&D has developed a modular system for adding test cell instruments or test cycles to a base application. Modules contain command sets specific to the instruments in use, with common commands used by a common test. This allows a single test to be used with a variety of instrument modules in different test cells, streamlining the test development process.

Runtime Software

The iTest system provides a fast, reliable environment for controlling the dynamometer and throttle settings in a coordinated manner. The runtime system will monitor defined parameter limits and coordinate a variety of actions on test cell instruments. All test data is available in a standard Windows format.

• User-friendly interface
• Flexible data acquisition and control for I/O systems and measurement instruments
• Monitoring of real-time limits
• Powerful diagnostic utilities
• Connection to DAC Web Server utility
