In the prior art, when a user needs to use hot water, the user turns on a household gas water heater to obtain the hot water. In the actual use process, because the current time is in the water consumption peak period, the water consumption flow rate fluctuates, namely the input water flow rate of the gas water heater fluctuates at the moment, and because the gas water heater is a water heater with multi-section fire rows, for example, in the embodiment of the invention, the gas water heater is a gas water heater with 2 fire rows, in the process of heating the input water flow, the problem of frequent switching of the fire rows is caused due to the fluctuation of the water flow rate, so that the problem of instantaneous temperature rise of the water during heating occurs, and the practical use of a user is disturbed.
In order to solve the above technical problem, in a possible embodiment, a technician optimizes a heating process of the gas water heater, for example, a standard heating program, before a user uses the gas water heater, first obtains a system compensation parameter based on an input water flow, wherein the system compensation parameter is a parameter related to the input water flow and changes in real time along with the change of the use time of the user, and adjusts an opening signal of the gas water heater based on the system compensation parameter, so as to obtain an adjusted opening signal after real-time compensation. At the moment, corresponding compensation control operation is executed according to the adjusted opening degree signal which changes in real time, so that the heating power of the gas water heater can be dynamically compensated and adjusted according to the current water flow actual condition, and the discharged water with stable temperature is discharged for users to use.
In the embodiment of the invention, by optimizing and improving the heating process and the heating method of the traditional water heater, the system compensation parameter related to the input water flow is firstly obtained before the water heater is used by a user, the feed-forward compensation is carried out on the water temperature heating process of the water heater according to the system compensation parameter, and the real-time dynamic power compensation is carried out according to the actual use duration of the user in the use process of the user, so that the discharged water with stable temperature can be provided for the user, the trouble caused to the user due to the instant change of the water temperature is avoided, and the user experience is improved.

In a possible implementation manner, after the plurality of pieces of test information are obtained, the preset temperature stabilization time, the preset compensation coefficient, and the average value of the preset compensation time are obtained in an averaging manner, so that the parameters are optimized, and the corresponding optimized temperature stabilization time, optimized compensation coefficient, and optimized compensation time are obtained, and further, the system compensation parameters are obtained.
In another possible implementation, in order to further improve the accuracy of optimizing the plurality of test information, the plurality of test information is further processed by using a clustering algorithm, so as to obtain clustered test information, and further obtain more accurate system compensation parameters.
In the embodiment of the invention, the system compensation parameters of the water heater are obtained according to the design data of the gas water heater, and are optimized on the basis of multiple tests, so that the accurate system compensation parameters are obtained, and the more accurate and effective regulation effect can be realized in the subsequent power regulation process.

In order to further ensure the validity of the opening degree signal after adjustment, technicians can further optimize and adjust each water heater in the using process or the factory debugging process of each water heater. In a possible embodiment, after obtaining the adjusted opening degree signal, the technician turns on the water heater and enables the water heater to operate normally, at this time, the technician may increase the input water flow and/or decrease the input water flow, so as to prompt the water heater to generate fire grate switching, and after the fire grate switching, obtain a first outlet water temperature curve or a second outlet water temperature curve of the outlet water temperature after the fire grate switching within the preset temperature stabilization time or the optimized temperature stabilization time.
