The invention relates to an intelligent water-saving system of an RO (Reverse Osmosis) machine and a control method of the intelligent water-saving system. The control method comprises the following steps of judging whether the water pressure is normal or not after power on, if yes, turning on a first water inlet solenoid valve, turning on a rinsing solenoid valve and rinsing; making water after finishing rinsing until a pressure tank is full, turning on a second water inlet solenoid valve, closing the first water inlet solenoid valve, turning on the rinsing solenoid valve, and rinsing; lowering the pressure to a critical value after the pressure tank gets water normally, judging whether the water pressure is normal or not, if yes, turning on the first water inlet solenoid valve, turning on the rinsing solenoid valve, rinsing, and then stopping the rinsing solenoid valve; collecting data simultaneously with a TDS contact and a temperature contact, and calculating through a chip to determine whether the system needs to be rinsed; if no, making water directly; if yes, turning on the first water inlet solenoid valve, and turning on the rinsing solenoid valve; making water until the pressure tank is full, turning on the second water inlet solenoid valve, closing the first water inlet solenoid valve, meanwhile turning on the rinsing solenoid, rinsing and then stopping the machine. According to the intelligent water-saving system, a water-saving effect is realized, and a way is paved for the machine to become a machine suitable for promotion in the market.
