The invention discloses a sound-light alarm device for railway crossing safety and an implementation method, and belongs to the field of railway crossing safety alarm. The sound-light alarm device comprises a control circuit board, a light emitting diode display circuit, a loudspeaker and a train track sensor, wherein the control circuit board comprises a power amplifier circuit, a voltage stabilizing circuit, a voice circuit and a main control circuit. When a train is close to a crossing, the main control circuit receives a trigger signal of the train track sensor, controls the loudspeaker to generate sound alarm through the voice circuit and the power amplifier circuit, controls the light emitting diode display circuit to generate light alarm, and calculates the time when the train head arrives at the crossing and when the train tail leaves the crossing through the main control chip. The system automatically controls to start and stop sound-light alarm, reminds pedestrians and vehicles of arrival of a train, improves the safety of a crossing, avoids safety accidents, guarantees the safety of railway transportation, and is simple in installation and low in cost.
一种用于铁路道口安全的声光报警装置及实现方法,属于铁路道口安全报警领域。声光报警装置包括控制电路板、发光二极管显示电路、喇叭和火车轨道传感器,其中控制电路板包括功放电路、稳压电路、语音电路和主控制电路。当火车靠近道口时,主控制电路收到火车轨道传感器的触发信号,通过语音电路和功放电路控制喇叭产生声音报警,控制发光二极管显示电路产生发光报警,并通过主控芯片计算出火车头到达道口和火车尾驶离道口的时间,自动控制开启和关闭声光报警,提醒行人和车辆火车到达,提高道口的安全性,避免安全事故的发生,保障铁路运输安全,同时安装简单且成本低廉。
