| Abstract: | This system uses sound wave sensor to detect the running train's noise wave after that conveys through the steel track. lt is amplified through process of restrict marpin, thensformed with A/D and treated with digit filter The signal is distinguished by a single chip processo/s procedure. When the signal of coming train is confirmed, the alarm sound is given out automatically The charateristic of the noise wave source is analyzed.Structure of the hardware and scheme of software are reported. |

| Keywords: | noise wave source sound wave sensor restrict margin amplifying single chip processor's procedure system flow |
