The technical scheme of the invention discloses a transit type vacuum excrement collecting system for a rail transit train. The transit type vacuum excrement collecting system comprises a pneumatic control panel, a vacuum generator and a transit box. The air pipeline of the pneumatic control panel is connected with the vacuum generator; the vacuum generator comprises a vacuum generator shell, a three-position five-way electromagnetic valve, a spray pipe, a piston, an adapter, a sealing plug, a vacuum switch, a silencer and a mounting bracket; the transfer box comprises a dirt transfer box, a swing door one-way valve, a membrane flap valve, a water-vapor separator, a grey water pressure protector, a liquid level sensor and a safety valve. The swing door one-way valve is connected with the dirt inlet pipeline of the transfer box, and the membrane flap valve is installed on the dirt outlet pipeline of the transfer box. The swing door one-way valve and the membrane flap valve are used forreplacing a pipe clamp valve, the pneumatic control panel and the vacuum generator are integrated, dirt back spraying is prevented, the vacuum generator integrates the vacuumizing function and the positive pressure applying function, and the whole system is safe, reliable, simple in structure and low in production cost.
