Komunikační a řídicí karta k elektronovému mikroskopu / Communication and control card for electron microscope

Robotka, Jan January 2011 (has links)
The main aim of this thesis is to design a communication and control card for an electron microscope, eventually for other equipments of the company Delong Instruments a.s., which is dealing with its development and production. This card should replace existing communication card because of its low computational performance. Also, it should replace control and measure card manned with A/D and D/A converters. Thus, the new card will be providing not only the communication with a superior PC and other electronic systems, but also the control of other subsystems of the electron microscope, the determining of processional states and the measuring of internal physical quantities. At the beginning the requirements were determined and the main concept was made with the inclusion of the simple block diagram. It was very important to choose a suitable microcontroller, which will be an intelligence of the whole card and so it will be the most important component. The accent was set mainly on the sufficient computational performance, high modularity of its periphery, good vision of the future innovation and support and, of course, the price. The next requirement was the implementation of the Ethernet, which will be used for the communication between the card and the superior PC. The microcontroller which was chosen have the core architecture ARM Cortex-M3 and it is described in separate chapter. The next part of this thesis is dealing with the main communication standard of the card, which is the Ethernet. After the general description, the Ethernet was mainly discussed in context of the chosen microcontroller. The possibilities of the application of higher layer TCP/IP protocols were also discussed. Implied part of the thesis was the selection of other important components, especially A/D and D/A converters. Its characteristics will have a big effect on the characteristics of the card. In the last and the most important phase the electrical scheme was designed and it was described in detail. This scheme is the main result of this thesis and it is the main document for the future realization. Designed card will be able to process and control 16 differential analogue input signals, 16 differential analogue output signals, 8 digital inputs, 8 simple digital outputs and 4 digital outputs triggered by optocouplers. It will be able to communicate with the superior PC over the Ethernet with the maximum bit rate of 100 Mbit/s, with other electronic cards over the serial line UART through the optical fibers and with other internal and external equipments over the RS-485 and RS-232.

Augustin, Stanislav January 2015 (has links)
The content of this diploma thesis is a hardware and software design of advanced weather station with image transmission. The meteostation consist of two units - outdoor and indoor unit. Outdoor unit provide processing measured values from temperature sensor, atmospheric pressure sensors, rain gauge and windmeter. It also provides processing of captured image and wireless transmission of measured values to indoor unit. Indoor unit should provide comfortable meteostation controlling and visualization of weather situation by web interface.
