S101: and monitoring whether the change of the water flow in the cold water inlet pipe of the gas water heater exceeds a preset threshold value within a preset time period.
As a specific implementation mode, a water flow sensor can be arranged on a cold water inlet pipe of the gas water heater, and the water flow sensor is used for acquiring the water flow passing through the cold water inlet pipe. For example, the water flow at the previous time may be compared with the water flow at the current time to determine whether the water flow changes suddenly, for example, when an absolute value of a difference between the water flow at the previous time and the water flow at the current time is greater than a preset threshold, it is determined that the water flow in the cold water inlet pipe changes suddenly. The interval duration between the previous moment and the current moment can be specified by self.
S102: and when the preset time period exceeds a preset threshold value, acquiring the current running state of the gas water heater.
As a specific embodiment, the current operation state of the gas water heater includes an initial water inflow of the gas water heater, an initial gas flow of the gas water heater, and a heat demand of the gas water heater.

More specifically, the following scheme may be adopted to determine the actual gas flow of the gas water heater by using the initial gas flow of the gas water heater: when the initial time (namely the time when the water flow in the cold water inlet pipe changes), the initial gas flow of the gas water heater is the actual gas flow of the gas water heater at the initial time; acquiring a preset gas flow change curve at other moments; and obtaining the actual gas flow of the gas water heater at other moments by using the initial gas flow of the gas water heater and the gas flow change curve.
As another specific implementation, the following technical solution may be adopted for determining the water replenishment amount according to the current operation state: (21) determining theoretical gas flow of the gas water heater by utilizing a preset corresponding relation between water inflow, heat demand and gas flow according to initial water inflow of the gas water heater and heat demand of the gas water heater; (22) calculating a difference value between the initial gas flow and the theoretical gas flow; (23) according to the difference value, obtaining the water supplementing amount at the initial moment by utilizing the corresponding relation among the water inflow, the heat demand and the gas flow; (24) acquiring a preset gas flow change curve; (25) and obtaining the water supplementing quantity at other moments according to the initial water supplementing quantity and the gas flow change curve.

The corresponding relation of the water inflow, the water inflow temperature, the set temperature and the fuel gas flow can form a one-to-one corresponding relation by acquiring the water flow, the water inflow temperature, the set temperature and the corresponding fuel gas flow data and verifying through theoretical calculation and a large number of experiments.

And feeding back the gas flow difference, the inlet water temperature and the set temperature to a data center, and calling the initial working water flow of the water supplementing device.
For example, fig. 4 is a data acquisition diagram of a variation trend curve (i.e. a data acquisition diagram of a gas flow variation curve), and as shown in fig. 4, data of gas flow from full opening to closing of a gas proportional valve are acquired in a laboratory, and a large number of experiments are performed to verify and correct, so that a data variation trend curve is formed and stored in a data center. And the subsequent water replenishing device controls the water flow curve to be carried out according to the change trend curve.
As a further embodiment, after the water replenishing is performed by the water replenishing device in accordance with the amount of the replenished water, the method further includes: acquiring the opening degree of a gas proportional valve of the gas water heater; and when the opening degree of the gas proportional valve is not changed, closing the water supplementing device.
Fig. 5 shows an example of the determination process of the amount of water replenishment during water replenishment: in the working process of the whole machine, the water flow changes suddenly, and the function of preventing overhigh water temperature starts to work. Through intake water flow size, the temperature of intaking, set for the temperature, data center is fed back to actual gas flow size, feeds back the initial working water flow size of moisturizing device and data variation trend curve to the main control board, and the moisturizing device begins work, judges whether the moisturizing device continues work or closes through whether the proportional valve changes simultaneously, supplements cold water through the moisturizing device, can prevent that the temperature of the play water is too high, prevents that the user from scalding and improves user experience.
