FP7-ALAMSAModular System DAKEL-XEDO©
Universal measurement and diagnostic system DAKEL-XEDO© was developed by ZD Rpety-Dakel company. Dakel's products have been seccesfuly used in nuclear power plants Mochovce and Jaslovske Bohunice (Slovak Republic) for more than 12 years. System XEDO was developed mainly for industrial applications but is used also in laboratory tests (Brno University of Technology, Aeronautical Research and Test Institute Prague, Academy of Sciences of the Czech Republic).
Examples of using
- All applications with physical phenomenon measurement using personal computer. Up to tens of XEDO measurement modules can be conected to one computer via Ethernet network. Monitoring of huge technological devices is posible this way.
- Measurement and digital processing of acoustic emission signals. This method is used for non-destructive testing of materials and components.
System description
XEDO is modular system. One communication card and up to 15 various input cards can be located in a metal box. Communication between cards within a box is realized by hi-speed bus. Each box is connected to control computer (computers) via Ethernet. Configuration of all units is automaticaly recognized after system switching (plug & play). Timebases of all input units in system are synchronized via Ethernet and hi-speed bus with 1 µs accuracy.
All parameters of input cards can be setted from computer and central reset for all boxes can be transmitted.
These types of XEDO units are available:
- Communication unit XEDO-FE. This unit works as a interface between box and Ethernet 100Base-TX. Maximum speed is 100 Mbit/sec. This interface allows connection of XEDO box to the existing Ethernet network which is used for communication between other devices. XEDO system uses IPX communication protocol.
- Acoustic emission parameters evaluating unit XEDO-AE. Alows sampling of signal from one sensor (speed up to 8 MSamples/sec), enumerates standard acoustic emission parameters, process emission events parametres for possible emission source localization.
- Unit for measurement of general physical values XEDO-IO. Alows measure up to 15 low-voltage (max ±10 V), low-frequency (max 2 kHz) signals. Furthermore measures frequency of 2 analog signals up to 32 MHz. This unit also includes 16 analog outputs (0-5 V).
- Passive (procesor-free) unit Tenzo, which can be connected to XEDO-IO unit. This combination realize 4 tensometric bridges. Analog output channels in XEDO-IO are used for bridges balancing.
Software
Each unit of XEDO system contains high-performance 16-bit Digital Signal Procesor (DSP). Software for DSP is stored in ROM memory on Printed Circuit Board (PCB) of unit. Even though ROM memory is a part of hardware, its content will be updated with the other software in system.
Control software for PC alows configuration setting and measurement with connected XEDO. Program is common for all kinds of units, which are existing and will exist. Software runs under OS Windows with standard drivers and with Sockets 2 extension.
