PLC Intelligent Transportation Signal Control Based on Algorithm of Function Block Conversion to Instruction List

PLC intelligent transportation signal control is the difficulty point in the urban rail transit control. In this paper, a kind of PLC intelligent transportation signal control method based on the algorithm of function block conversion to instruction list (hereinafter referred to as AFBCIL for short) is put forward. In this method, the control deviation of the PLC intelligent transportation signal is equivalent to the inter-symbol interference signal, and the control performance of the PLC transportation signal is improved by the feedback information from the functional block conversion to instruction list. The simulation results show that: The experimental results have verified the versatility of the algorithm put forward in this paper, which can convert complex control logic function blocks with multiple outputs into the instruction list statements. And during the process of compilation and conversion, the proposed method has simplified the program very effectively, saved more memory space, and improved the efficiency of the compilation and conversion of the PLC function block diagram.
