Test bench and Measurement freelance Engineer

This blog is dedicated to expertise and systems development of system of Supervision, Control, Test and Measurement and especially on LabVIEW, TestStand and LabWindows/CVI.

 

 

The aim of this test bench is to validate electronic measurements and audio signals. The system must be enough flexible to permit the test of several models of car radio.

Calibration system for oil well sensors. This system measures the pressure and the temperature behavior of the sensors along one week to one month. All measurements are safeguarded in a data base to be analyzed and to create reports/ratios.

TestStand is a instruction sequences engine and a development environment for creating a test sequencer evolved several common test for different products. We have a generic software that loads, as the test product, sequences specifying actions, tests and tolerances, and components (such as DLLs) for communication with the hardware.

LabWindows is a development environment in C language for the implementation of test systems, measurement and instrumentation. Thus, it is possible to enjoy both the power and precision of the C language but also libraries of functions for instrumentation and signal processing from National Instruments.

With LabWindows / CVI, you can develop:

software for Windows (exe) or UNIX Linux, libraries (DLL, Active X,. NET), instrument drivers, on embedded targets, on real-time target. Système de calibrage de sondes de puits de pétrole

I am a supervision, control, test and measurement specialist. For this reason, my work consists to conceive and develop automatic or semi-automatic systems of measurement, validation or qualification of products for industrial or scientific applications.

With my experience since 1998 in the field of test and measurement, many of my clients appreciate my analysis and advice to optimize and improve both technically and in terms of production processes and validation. Indeed, test and measurement benches are central elements that identify with precision the problems caused by a malfunction or bad process: settings of production machines, manual actions or arrangement.

I support my expertise on the use of:

software solutions with: LabVIEW LabWindows/CVI TestStand Measurement Studio .NET material solutions containing: data acquisition card relay matrix card, DIO signal generator, DAQ oscilloscope, analyzer compatible with the following standards: PXI, PXI express, VXI GPIB, USB, FireWire PCI, PCI express, Compact PCI RS-232, RS-422, RS-485, AK protocol CAN, VAN, LIN, I2C, ARINC Job

I intervene in the various phases of life of the projects:

• Study/Research/Documentation

Feasibility study Analyzes and research solution Search for materials Helps with the documentary drafting Retro-engineering (analyzes systems without documentation)

• Software of tests (dregs to the material)

Development of advanced software functions Analyzes, second reading of source codes Debugging of software functions Drivers of instruments Development of simulators of instruments

• Software applicatifs (not dregs directly with the material)

Complete development of software Analyzes, second reading of source codes Debugging Course of specifications of tests
