The automation system developed by Alma Automotive is highly flexible and perfectly adapts to the configurations of available test systems. This tool offers a wide range of functionalities, from real-time management of all actuators to the simple sending of requests to external controllers. In addition to controlling speed and torque with precision, the system is capable of accurately managing air, oil, water, fuel conditioning systems, and set-points for battery emulators. Furthermore, it allows for complete control of every component in the test facility, including ventilation, fuel supply, and fire safety devices, both locally and remotely.
The test control software developed by Alma Automotive is based on National Instruments' cutting-edge software environment called VeriStand. This software allows for the configuration of automated procedures to control devices, efficient data acquisition, management of channels (including scaling, alarms, and mapping), and the creation of calculated channels. Moreover, it provides the capability to execute simulation models based on platforms such as Simulink® and LabView®.
What makes Alma Automotive's solution unique is its use of a standard interface like VeriStand, enriched with customized models and components. This solution is highly versatile, functioning seamlessly in both Real-Time and PC host environments. Thanks to this flexibility, Alma Automotive offers a comprehensive and reliable solution for test control and automation, ensuring high-quality results and increased efficiency in the development and testing process.
Automation plays a crucial role in supporting various phases of the testing and calibration process, both in static and dynamic conditions. When applied to a test bench, the automation system developed by Alma Automotive proves to be particularly advantageous for several reasons, including:
The application is always tailored to the customer's needs, and since the source code is available, the customer can independently manage system customization and evolution, maintaining full autonomy.
The dyno bench control system is based on hardware platforms compatible with NI Real-Time software.
Hardwarewise, several options can be chosen, depending on the application: cRIO, PXI or MXI+PC-RT. In the latter case, the Real-Time OS runs on a high performance’s desktop PC, connected to the Chassis containing the I/O Modules via MXI Express BUS interface. Finally, the Host PC is connected via Ethernet to the Real-Time controller, offering a user interface for tests management and monitoring.
The test bench software is divided in two parts:
