Modular measuring system for measuring vehicle air conditioning

The solution is based on a module system called CRONOS flex by imc Berlin. The system consists of modules communicating over a bus very similar to CANbus. The system is modular; for each specific measurement, it is possible to “assemble” the instrument from individual modules so that it contains all the necessary technology and, at the same time, it is as small as possible. The figure illustrates the mechanical concept. By simply snapping the modules to the base unit, a complete system is created, with the number of channels required in the form of a single device.

princip

On the above principle, it is possible to build a device that will contain a maximum of 128 channels. All measured channels are equipped with thermocouple temperature sensors. The PELI case was delivered for transport.

systém

The basic system module has a left-hand handle that incorporates a DC power supply, including an uninterruptible power supply for 30 seconds. The module is equipped with a pair of CANbus interfaces and a pair of LIN. Its connection to the computer is possible via LAN cable or via WiFi. The module is equipped with sufficient memory for independent measurement.

The eight-channel ISO2-8 modules are used for analog signal collection. Each of them measures eight voltage channels in the range of 50 mV to 60V, currents in mA ranges, and temperatures from most types of thermocouples and Pt100. The maximum sampling frequency is 5 kHz. Input voltage allows measuring directly on the vehicle network, without any voltage divider.

System configuration is provided by the customer. It is configured and operated via the imcStudio software package. Data evaluation is performed by Famos professional. Our company provides on-demand support.
