Software for laboratory equipment

By Christian Pehle,

  • Development of software for steering, data aquisition and evaluation of laboratory equipment for measuring friction, abrasion and general tension measurement
  • Assistance for hardware development
  • Schooling of customers in theoriy and practise in the use of the laboratory equipment
  • Environment and tools: LabView, C#, C++, Visual Studio .Net

Development of database modules for measurement data

By Christian Pehle,

  • Converting / preparation of measurement data from a source, storing the data in an MS-Access- (Jet) database
  • Development of routines for reading from database with sorting, filtering, generating of reports etc.
  • Environment and tools: LabView, C#, Windows XP

Development of some simulators for CAN-Bus-Devices

By Christian Pehle,

  • Realisation of simulators for peripheral devices, that are connected via CAN-Bus to a central control unit. This controller is the device under test. In this way it’s possible to test the control unit with an automated flow (test bench ipFit) without connecting all peripherals manually.
  • Tests of the simulators
  • Environment and Tools: C# (MS-Visual Studio 5), NUnit for the tests of the simulations, Doxygen for source code documentation

By Christian Pehle,

  • Tension measurement, temperature compensation, optimisation of characteristics
  • Prozessor MSP430-Serie (Texas Instruments)
  • Adaption of the AD-converter via SPI-Bus
  • Grafic display and Touchscreen
  • USB-connection to a Windows-PC for parametrisation and first start
  • Development of a GUI for the PC (C#)
  • Design of Software-Architecture
  • Realization in C
  • Documentation
  • Project management
  • Environment and Tools: Code Composer Studio (Texas Instruments), Visual Studio (Microsoft)

Analysis and simulation for a vacuum system

By Christian Pehle,

  • Analysis of the type of control of the drive
  • Development of a simulator to control and drive on the basis of physical examinations
  • Realization of the simulators in LabView
  • Optimization of the regulator
  • Environment and Tools: LabView (National Instruments), MPLAB IDE (Microchip), Scrum, SVN / Tortoise

Test development / Assistance for start of production of a home appliance

By Christian Pehle,

Safety system for a cooker

By Christian Pehle,

Safety system to prohibit fire and smoke in the kitchen

  • Design and realization of the software architecture for four modules:
    • Sensor to monitor the temperature of a hob, and to monitor the movement of persons
    • Smoke sensor
    • Turn-off unit for the mains, tri-phase and one-phase
    • RF-adapter to control the system via USB with a PC
  • Realization of the RF-protocol (868MHz) between the modules
  • Implementation of an interface to smart-home-systems (e.g. Homematic)
  • Development of a intuitive program running on a PC to control the system (Microsoft Windows 7 and 10)
  • Formulation of testing routines
  • Documentation
  • Development environment and tools: MPLAB IDE (Microchip)
