In order to solve the problems of bad shunting and red light strip phenomenon at electric railway section caused by the defective of asymmetric pulse track circuit receiver formerly, a new type of asymmetric impulse track circuit receiver is designed. It takes the PIC16F887 single-chip microcomputer as central processing unit of the system, realizes processing and judging the asymmetric impulse from the track transformer automatically. The article focused on the receiver work flow, hardware circuit and software design.
