Dewesoft X

The data acquisition module is intended for obtaining data from various devices. Dewesoft offers a wide range of input interfaces for a wide variety of signals. It enables most analog-to-digital DAQ cards with various capacities (from 10 Hz to a 10 MHz speeds) sampling with a resolution of up to 24 bits. Analog-to-digital cards are connected to a computer via several interfaces (USB, EtherCAT and Ethernet protocols). Different signal amplifiers are available for measuring voltage (micro to high voltage), current, resistance RTDs, strain, temperature (thermocouple, thermistors, RTDs), potentiometer, vibration, inductive detection, LVDT, IEPE and more. The Dewesoft software package offers multiple meter interfaces for the detection of various events. With them, the user can capture and measure the number of digital signal transitions (positive and negative fronts), frequency, period and pulse width. There are several types of counters that improve counting accuracy. Dewesoft software and DAQ hardware offers a special patented counter interface called SuperCounters®. In some cases, there is a need to capture the video signal as well. Basically, simple DirectX or IEEE 1394 cameras with a few frames per second or high-speed cameras with internal memory can be used, reaching speeds of up to 100,000 frames per second. In addition to classic cameras, the software package also enables the capture of images from FLIR thermal imaging cameras. In the automotive industry, GPS receivers are essential. Global Positioning System, which is used to detect the position on the ground, the speed of the object and to accept the exact absolute time. Due to the great need for higher position refresh rates and speeds, which is important in dynamic vehicle tests (basic GPS receivers have refresh rates once per second), the software package allows the support of faster GPS devices that allow up to 200 Hz refresh rate.[8]

In some measurements, there is a need for mathematical operations that enable the mathematical analysis over the measured data. The Dewesoft software package enables most arithmetic, logic, algebraic operations and different types of filters (IIR - Infnite Impulse Response, FIR - Finite Impulse Response) for processing of the measured signals. In addition to all the mentioned basic mathematical operations, the product also enables some advanced and more complex and specialized mathematical modules, such as a module for measuring the quality of electric current, power analysis, modal analysis, torsional vibration analysis, vibration analysis, order tracking analysis, analysis of internal combustion engines, sound analysis, FFT analysis, analysis vibrations on the human body and many others.[9]

The Dewesoft software package uses special visual widgets, to which the appropriate measurement data are assigned to display data during the measurement in real-time. The basic visual building blocks for screen printing are:

• analog and digital numerical displays of average, maximum, minimum and mean root values of signals;
• time format displays;
• display of the frequency spectrum of signals;
• oscilloscope
• orbit graph;
• review of the time recording of signals for a longer period of time;
• video display;
• review of the x-y record over a long period of time;
• tabular display;
• x-y-z record overview (3D graph);
• display of earth coordinates with interactive mapping options;
• others (lines, text, pictures).

The Dewesoft software package contains basic measuring instruments such as an oscilloscope and a frequency analyzer, as well as special measuring screens defined by the user. During operation, the user can switch between different instruments that operate in parallel, and in no way affect the course of the measurement.[10]

The software product allows different types of data storage. The most common is to store bare data at the desired speed. The product also enables the storage of reduced data at a lower sampling rate (e.g. once every second) for a longer measurement time. In this mode, the minimum, maximum, mean and mean root values for the selected save cycle are stored. Ready-to-store data is stored in a file or database. Currently, data can be written to a file at a rate of more than 500 MB of data per second[11]. The patented storage data file structure allows it to immediately open the file and display the data on the screen even if the data file size is several Gigabytes large. Dewesoft X software also offers modules to allow storing the data into relational databases such as MS SQL or time series database like InfluxDB[12]

Dewesoft X allows exporting data to the following file formats:[13]

• MS Excel - standard spreadsheet software
