Its core function is to achieve water source storage, transportation, distribution, and water quality guarantee.

[0003] Chinese Patent No. CN207072343U discloses a train water supply system, which includes a first clean water tank arranged below the exterior of the train and a second clean water tank arranged inside the train. The first clean water tank and the second clean water tank are connected by a water pump arranged inside the train, and the second clean water tank supplies water to the water-using equipment in the train. The train water supply system provided by the embodiment of the utility model can reduce the water pump head, save the space under the car, and reduce energy waste.

[0004] In view of the above related technologies, in the prior art, an electric water heater is connected to one of the faucets, resulting in no hot water supply to other faucets, reducing the applicability of the train water supply system. Summary of the Invention

The main water tank is internally provided with a first liquid level sensor. The sub-water tanks are installed above the car body underframe, and one sub-water tank corresponds to one carriage. The sub-water tank is internally provided with a second liquid level sensor and a third liquid level sensor. The second liquid level sensor is located above the third liquid level sensor. A water pump is installed above the car body underframe. The water intake end of the water pump is connected to the main water tank, and the water outlet end is connected to the sub-water tank. A toilet room and a water dispenser are arranged inside the carriage. The water dispenser is internally provided with a heating module. An electric heater, a toilet, and a washbasin are arranged inside the toilet room. The sub-water tank is connected to the electric heater, the water dispenser, and the toilet. The dirt tank and the vacuum toilet tank are both installed below the car body underframe. The water dispenser and the washbasin are both connected to the dirt tank, and the toilet is connected to the vacuum toilet tank.

[0007] By adopting the above technical solution, when the train arrives at the station, the water pipe is injected into the main water tank. Subsequently, through the detection of the second liquid level sensor and the third liquid level sensor, the controller controls the water pump to pump water into the sub-water tank until the water in the sub-water tank reaches the position of the second liquid level sensor. When the toilet in the toilet uses water, the sub-water tank transports water to the toilet, and the toilet waste is finally discharged into the fecal collection box. Similarly, water is transported to the water heater and the washbasin. When drinking water is needed, the sub-water tank transports water to the water dispenser. The waste water discharged from the washbasin and the water dispenser enters the waste box, realizing the water supply effect of the water supply system. By setting a water heater on the washbasin and a water dispenser in the carriage, passengers can enjoy hot water when washing or drinking water in the corresponding carriage, improving the humanization and comfort of the train. Compared with the prior art, the applicability of the train water supply system is improved.

[0047] The implementation principle of an intelligent water supply system for a train in an embodiment of the present application is as follows: When the water level in the sub-water tank 12 reaches the position of the third liquid level sensor 122, the control system controls the water pump 14 to pump water into the main water tank 11 until the water level reaches the position of the second liquid level sensor 121.
