Multifunctional PC/104 Module

Tme multifunctional PC/104 module has been developed for Applied Precision, spol. s r. o., the company dealing with measuring systems.

The module provides eight 16-bit analog inputs (each with four voltage ranges), one analog output, 32 digital IO and four counters.

The board is based on the gate array (providing the bus interface with the interrupt circuits, data buffers, etc.) and the microcontroller for controlling of the analog inputs and output.

Display Panels Again

The modified display panels for controlling the manufacturing of the VW Passat ceiling interior parts has been developed for the Czech local office of Grupo Antolin Autoform, a well-known manufacturer of the components for car industry.

The display panels are part of the system of the manufacturing process monitoring. They are controlled by the manufacturing manager and all displayed data are available through the company intranet.

TEDIA has ensured the development and manufacturing of the panels. The whole system including the software support has been developed and installed by PROTECH MATIC, s. r. o.

Independent Power Protection for Research Nuclear Reactor VR-1 Vrabec (Sparrow)

TEDIA has been cooperating in rebuilding of the VR-1 reactor control system. TEDIA has been a general supplier for Škoda Nuclear Machinery. TEDIA has ensured the development and manufacturing of the independent power protection (IPP) units including most of the firmware and the converters for communication via fibre optics.

The system of IPP represents a part of the control system, which is required to be the most reliable in the whole structure. The task of IPP is to ensure the power safety limits of the nuclear reactor in the event of failure or even malfunction of the operational power measurement (OPP).

The units have been realised using the most modern electronic components (low-noise amplifiers for processing of the input signal of tens of microvolts, stabilized low-noise high voltage power supplies, powerful MCUs and CPLD and FPGA gate arrays) and redundant circuitry.

The critical part of the firmware is processed concurrently in two microcontrollers, that are separated from the IO signals and communication lines by another two microcontrollers. The inter-processor communication has been realised by several dual port memories with control registers (implemented in FPGA). This is checked by another (the fifth) microcontroller. The independent clock generating is performed in CPLD. There have been realised three series interfaces providing the fibre optics for communication with the supervising terminal, with the displays and for service purposes.

Although tens of electronic security features ensure high reliability and operation error resistance, there are four IPP units operating in the reactor control. Three units are running and the fourth is on standby. The supervising system inactivates suspicious unit using the "two out of three" method and its operation is performed by the fourth unit then.

PCI Card - Video Signal Generator

This special diagnostic card has been developed for Panasonic AVC Networks Czech, s. r. o., a world-known manufacturer of audio and video accessories.

The card provides the video signal generator, supporting the PAL, NTSC and HDTV systems, interlaced and non-interlaced modes and RGB, YUV, composite video or S-video output data. All signals are fully configurable (amplitude, frequency, ...), including the synchronization signals.

The card provides fast 8 MB RAM, efficient FPGA for data processing and output circuits providing fast 10-bit D/A converters, amplifiers and PAL/NTSC video encoder.

When transmitting the video data from RAM into the D/A converters, the FPGA processes several conversion operations (RGB to YUV conversion, brightness and contrast adjustment, color compensation, etc.). The output data stream is nearly 280 MB/s at the HDTV mode.

The Windows drivers and the conversion utility program of several data formates have been developed. The conversion utility converts BMP, TIFF, PCX, GIF into internal RAW format (index or truecolor mode).

Special Module for Detecting of Anomalies in the 50Hz Signals in Energy Networks

The three-channel module EGU-01 for detecting of the anomailes in the energy networks has been previously developed for EGU, high voltage laboratory, a. s.

The innovated 2005 version EGU-02 provides four channels with microcontrollers and A/D converters (one set for every channel) and a gate array for evaluating of the events of four analog and one digital channel. The modules may be lined up together to increase the number of analyzed signals.

The algorithm implemented in the microcontrollers works as a harmonic signal generator with the frequency-phase coupling to the input signal and the voltage feedback control at the output. The generated signal follows the ideal harmonic signal for certain channel and the real digitized data are processed continuously within the chosen tolerance zone. When signal is out of the tolerance zone, the synchronization event is generated and transferred through the gate array and the interface to the recording device.

External Module for Audio Signal Digitization

This special custom-made module has been developed for the audio signal digitization.

The module allows to digitize up to eight audio channels in several modes (from 8-bit/8kHz to 16-bit/48kHz). The inputs provide programmable gain amplifiers with the 0.5dB steps. The digitized signals may be transferred simultaneously using the RS-422 line with the baud rate of 2.048 Mbit/s or using the E1 G-703 interface. The module configuration is realized using the RS-232 line or ethernet. Ethernet may be also uses for sending data into the selected audio input.
