The invention relates to an automatic fire extinguishing method and device. The method comprises the steps of detecting the temperature and smoke concentration of a detected area through a first smoketemperature combined detector, and sending the temperature and smoke concentration to an alarm host; performing judgment processing according to first temperature data and/or smoke concentration datathrough the alarm host, and outputting alarm signals to a train control system according to the judgment processing results; finding the solenoid valve ID of a first thermoelectric double-control solenoid valve corresponding to the first smoke temperature combined detector through the train control system according to the detector ID, and sending solenoid valve control start instructions receivedto the first thermoelectric double-control solenoid valve according to the solenoid valve ID; and starting the first thermoelectric double-control solenoid valve according to the solenoid valve control start instructions, and spraying out media in a fire hydrant box through nozzles arranged on a pipeline where the first thermoelectric double-control solenoid valve is located for automatic fire extinguishing of the detected area. The automatic fire extinguishing method is used for automatic fire extinguishing of electrical cabinets and other electrical devices.
本发明涉及一种自动灭火方法和装置,其中方法包括:第一烟温复合探测器对被检区域的温度和烟雾浓度进行检测,生成第一温度数据和烟雾浓度数据,并发送给报警主机;报警主机根据第一温度数据和/或烟雾浓度数据进行判断处理,并根据判断处理结果向列车的列车控制系统输出报警信号;列车控制系统根据探测器ID查找与第一烟温复合探测器对应的第一温电双控电磁阀的电磁阀ID,并且根据电磁阀ID和接收到的电磁阀控制开启指令发送给第一温电双控电磁阀;第一温电双控电磁阀根据电磁阀控制开启指令开启,消防箱内的介质通过第一温电双控电磁阀所在管路上设置的喷头喷出,用以对被检区域进行自动灭火。本发明用于电气柜等带电装置的自动灭火。
