The invention relates to a transit type vacuum excrement collecting system for a train, and a control method. The system comprises a dirt box, a transfer box and a grey water box, the other end of a grey water box drainage pipe is connected to a dirt inlet pipe between a toilet stool blow-down valve and a second valve or directly connected to the transfer box, and a vacuum switch is installed on apositive pressure gas circuit in front of the grey water blow-down valve or directly installed on a vacuum generator. Meanwhile, the steps of vacuumizing fault judgment, low-pressure protection switch fault judgment, tank full liquid level judgment, position sensor and blow-down valve fault judgment and the like are added to control logic of the system. Therefore, the phenomenon that dirt and grey water in the transfer box are reversely sprayed from the toilet stool and the hand washing sink due to pipeline blockage or functional part damage is completely eradicated, meanwhile, the system canaccurately judge whether a device or a system component breaks down, an alarm is given only when it is judged that the system component breaks down, sanitary equipment is controlled to be used temporarily, and the working stability and reliability of the system are further improved.

    本发明涉及一种列车用中转式真空集便系统及控制方法,系统包括污物箱、中转箱和灰水箱,将灰水箱排水管的另一端接入便器排污阀与第二阀之间的进污管上或直接接入中转箱,将真空开关安装在灰水排污阀之前的加正压气路上或直接安装在真空发生器上。同时在系统的控制逻辑中增加了抽真空故障判断、低气压保护开关故障、箱满液位判断、位置传感器和排污阀故障判断等步骤。使得本发明杜绝了管路堵塞或功能部件损坏造成的中转箱内的污物和灰水从便器和洗手池中反喷的现象,同时也使系统能够准确判断是器件的故障还是系统部件出现故障,只有判断系统部件出现故障才报警,同时控制卫生设备暂停使用,进一步提高了系统的工作稳定性和可靠性。
