摘　　要：本次设计CRH3型电力动车组的火灾报警器是一个能精确检测列车运行过程中其内部环境的烟雾情况,同时有报警系统的检测设备。该设计由五个模块组成,分别为:列车烟雾警报信号的采集控制电路、A/D模数转换控制电路、单片机控制电路、温度警报控制电路、声光报警控制电路。本次设计的主要元件是传感器、信号转换器以及单片机,加之其他电子技术的配合,由温度传感器检测各个车厢的温度及烟雾并上传至ATmega16单片机进行处理,并把传感器监测的结果进行了数据采集和信息处理。如果温度超过了预设的列车警报温度阈值,蜂鸣器将由单片机驱动进行报警,LED灯光闪烁以达到烟雾报警的效果。In this design,the fire alarm of the CRH3 electric train unit is a detection device that can accurately detect the smoke in the internal environment of the train during the operation of the train and also with an alarm system.The facility has five template groups:acquisition control circuitof train smoke alarm signal,a/d analog-to-digital conversion control circuit,single-chip control circuit,temperature alarm control circuit,sound and light alarm control circuit.The main components of this design are sensors,signal converters and single-chip microcomputers.Together with other electronic technologies,the temperature sensor detects the temperature and smoke of each compartment and uploads them to the ATmega16 single-chip microcomputer for processing,and uses the buzzer to monitor the results of the sensor.Data collection and information processing are carried out.If the temperature exceeds the preset train alarm temperature threshold,the buzzer will be driven by the microcontroller to give an alarm,and the LED lights will flash to achieve the effect of a smoke alarm.
