Programování bezpečně kritických aplikací pro železniční zabezpečovací zařízení

Abstract

This thesis deals with the design and implementation of control application for Outputs Control module that is the part of complex interlocking plant FRIS (Electronic control block of grade crossing). This module will be used for controlling less-critical partial parts of grade crossing in the form of switching different indicators and lighting elements, switching additional camera system and lighting of grade crossing in the evening. To provide these functions this module is equipped with four contactless outputs. Outputs Control module consists of two independent channels, mutually communicating through UART. Communication with the Control module passes through CAN bus and the data transmission among peripherals (within one channel) is ensured via I2C bus. The development environment KEIL µVision3, version 3.6, was used for creation of the control application. Language C was selected as a programming language.
