The invention provides a secondary water supply equipment control method and system based on a model. The secondary water supply equipment control system comprises a water supply pipe network water outlet pressure detection meter, a controller, a variable-frequency governor and a pressurization water pump, wherein the water supply pipe network water outlet pressure detection meter, the controller, the variable-frequency governor and the pressurization water pump are electrically connected in sequence. The secondary water supply equipment control system further comprises a user water consumption port flow meter. The output end of the user water consumption port flow meter is electrically connected with the input end of the controller. The user water consumption port flow meter accurately calculates the water consumption quantity of a user water outlet and inputs flow data into the controller. The controller builds a water supply model according to the flow data and corresponding time, controls frequency changes of the variable-frequency governor according to the flow value at each time point in the model, and then controls the rotation speed of the pressurization water pump. The secondary water supply equipment control system realizes high-accuracy control and a higher response speed in the secondary water supply equipment control process by modeling the water supply data, saves water and electricity, better avoids overpressure of a water supply pipe network, guarantees the safety of the water supply pipe network and provides better water consumption experience for a user on the water consumption side.

The invention discloses a constant temperature water supply control method and system of a hot water machine. The constant temperature water supply control system of the hot water machine simultaneously controls the water level through the electrical connection of a heating device, a water supply device, a water level sensor, and a temperature sensor to a central controller. and temperature; and through the constant temperature replenishment control method of the hot water machine, the multiple water levels and temperature differences at the warning water level position, the first water level position and the second water level position are judged and controlled; the water level of the water tank is realized at the first The first water level position and the second water level position change within the range, and the water temperature of the hot water machine changes within the tolerance range of the supplementary water temperature, so as to ensure the constant water temperature of the hot water machine and effectively avoid the abnormality of the heating device caused by the lack of water in the water tank Protect against downtime or damage and give users a good water experience.

The invention discloses a zero-cooled water control device with preheating and over-temperature protection, comprising a water heater body, a circulation pump, a water outlet temperature probe, a gas valve and a controller, and the circulation pump, the water outlet temperature probe and the gas valve are respectively electrically connected to the controller , the controller can automatically match a preheating over-temperature temperature difference according to the preheating preset temperature during the preheating process. Also disclosed is a control method using the zero cold water control device with preheating and overtemperature protection. The present invention has at least the following advantages: 1. The size of the preheating over-temperature temperature difference can be automatically adjusted according to the preheating preset temperature, so that the zero-cooling water control device can meet the needs of water occasions in different seasons, and further improve the self-adaptive ability and Degree of intelligence; 2. The zero-cold water control device of the present invention has the function of preheating and over-temperature protection, which effectively prevents the temperature of the outlet water from being too high during the preheating process, improves water safety and water experience, and avoids hot water scalding accidents.

The invention discloses NFWGIII-type multistage tank body water supply equipment, which comprises a control system and a flow stabilizing tank device which is arranged between a water supply main pipe and a water discharging main pipe, wherein the flow stabilizing tank device, as a multistage tank body structure, comprises a flow stabilizing tank and a voltage supplementing tank body; a voltage supplementing capsule body is arranged in the voltage supplementing tank body; a water inlet branch pipe, which is connected to the voltage supplementing tank body, is arranged on the water supply main pipe; the water outlet of the water inlet branch pipe communicates with an opening of the voltage supplementing capsule body; the flow stabilizing tank body is connected to the voltage supplementing tank body by virtue of a negative pressure inhibiting device; the negative pressure inhibiting device is connected to the control system; and the negative pressure inhibiting device communicates with a cavity of the voltage supplementing tank body outside the voltage supplementing capsule body by virtue of a pipeline. The water supply equipment, through a cooperated operation with the multistage tank body structure, offers voltage supplementing double guarantee by virtue of the voltage supplementing capsule and gas, so that a negative-pressure inhibiting effect of municipal water supply is enhanced and the safe running of a municipal pipe network is guaranteed.

The invention discloses a control method for an electric water heater, comprising: S2: entering the hot water circulation mode; S4: detecting the water temperature T1 of the water inlet pipeline; S5: judging whether the water temperature T1 is less than or equal to the first temperature threshold Ts1, and if so, entering the step S6, if not, return to step S4; S6: turn on the first switch, turn off the second switch, and then start the water pump; S7: continue to judge whether to end the hot water cycle, if so, go to step S8; S8: turn off the water pump. In the control method of the electric water heater of the present invention, the water temperature of the upper inner tank is designed to be not less than the water temperature of the lower inner tank, and the water is switched to the lower inner tank when the hot water is circulating, so as to ensure that even if the user uses cold water at the water end It will not be scalded, which improves the user's water safety and water experience; in the normal working mode, switch to the water outlet from the upper inner tank to ensure that the user has enough hot water when bathing, and better satisfy the user's bathing experience.
