Panel meassurement device
Vaško, Pavel ; Kaczmarczyk, Václav (referee) ; Bradáč, Zdeněk (advisor)
The master thesis includes a literature search, which is focused on questions around panel measure instruments for measuring analog voltage signals. There is the block diagram and the concept of measuring voltage values designed from collected information and defined requirements to the device. In the next step a design of the circuit diagram is created and published and consequently transferred into PCB. The whole board has been fabricated, assembled and tested. The firmware development starts with the definition of basic functional blocks for using of internal elements of the device, which is followed by the implementation of the Modbus slave station service routine. The top part presents graphical user interface on the device.
