[0002] The HXD1 series electric locomotive's integrated restroom controller is a mechatronic product integrating air, water, and electrical circuits. Its control system utilizes a single-chip microcomputer (A1 controller). By controlling electrical components such as the sewage discharge solenoid valve, flushing solenoid valve, handwashing solenoid valve, water pump, and sensors, it implements functions such as quantitative flushing, water tank level alarms, and sewage tank level alarms. The HXD1C locomotive's restroom control system incorporates an auxiliary sewage tank heating controller (A2 controller) that effectively controls sewage tank temperature and prevents the heater from burning out.
