Data logging software tackles vehicle acoustics

Posted By : Mick Elliott

With the release of IPEmotion 2017 R1, IPETRONIK offers an updated version of its measurement data logging software. The new release focuses on the further development of acoustics and online/offline vehicle bus analysis as well as on the integration of CAETEC hardware.

The acoustic module developed for testing the vehicle acoustics has been extended to include new evaluation functions such as root-mean-square value, peak-to-peak, dbB and dbC.

Furthermore, new analysis operations allow the overall level to be calculated as well as the configuration of order analysis and filters with adjustable bandwidth.

In addition, direct audio output is possible via the Campbell diagram.

This allows users to listen to the recorded measurement data instantly, which in turn makes judgement of the quality and any further analyses possible. The vehicle bus analysis can be performed online and offline with the Traffic Analyser instrument. The filtering for specific CAN IDs or CAN ID ranges is particularly helpful for a practical application.

The online measurement for CAN and CAN FD messages allows acceptance filters to be configured. Complex filter ranges can also be defined conveniently via DBC description files.

FlexRay traffic can be converted into signals via Fibex and Autosar description files during online and offline traffic analysis.

The filtering of FlexRay and LIN traffic messages is planned for the next release stage IPEmotion 2017 R2. The first integration step with release 2017 R1 sees the product lines of IPETRONIK and CAETEC merging. With the new ETH gateway CLFD box, the company has a highly compact and multi-channel interface module, whose 16 CAN high-speed inputs, two FlexRay, eight LIN and four DIO channels can be connected to IPEmotion.

An Ethernet connection to the PC permits – via corresponding description file imports (e.g. OBD, DBC, Aurosar, A2L, Fibex) – the implementation of multi-channel CAN, LIN, FlexRay traffic and signal-based measurements. The system integration of the CAETEC and IPETRONIK product lines places special focus on the ARCOS 1.5 data logger with two operating systems.

For classic logger operation, the system is configured with either a 32 or 64 bit Linux operating system and dataLog/Phoenix software.

The MDF4 measurement data generated can be imported into IPEmotion and the IPEcloud and evaluated. For applications that envisage measurements with gateway operation on a notebook, it is worthwhile installing the Windows operating system with IPEmotion.

This allows test engineers to use all the plug-ins installed on the ARCOS and to view the corresponding online measurement data on their notebooks using the IPEmotion software. Besides CAN, LIN, FlexRay traffic and protocol measurement data, this also includes the data of integrated USB and IP cameras.

Furthermore, the CLFD box is integrated into IPEmotion via the protocol plug-in so as to allow identical physical bus interfaces to be used in logger and gateway operation. IPEmotion is an efficient software solution for online data acquisition and processing. With its intuitive handling and simple connection to any hardware, It ensures maximum flexibility for all measurement and test tasks. Innovative program libraries and a plug-in concept based on the open-source principle ensure smooth communication with any measurement hardware.
