Problems solved by technology
The gas proportional valve of gas heating equipment includes an electromagnetic coil. When the gas heating equipment is working, when the electromagnetic coil of the gas proportional valve is magnetized to a saturated state, at this time, even if the magnetic field is removed, the magnetic induction of the electromagnetic coil will not follow the original path Return, but decrease along a curve slightly higher than the original path, that is, hysteresis occurs, the existence of hysteresis makes the opening angle of the gas proportional valve not open or close according to the preset angle, and then There will be problems such as excessive flue gas emission, poor product constant temperature performance and high energy consumption, resulting in poor user experience

The invention provides a control method and a control system of fuel gas heating equipment, the fuel gas heating equipment, a computer device and a computer readable storage medium, wherein the fuel gas heating equipment comprises a fuel gas proportional valve. The control method of the fuel gas heating equipment comprises the following steps: receiving the input temperature of the fuel gas heating equipment; determining the first openness of the fuel gas proportional valve according to the input temperature; determining a first current and a second current of the fuel gas proportional valve according to the first openness; and controlling the current of the fuel gas proportional valve to be converted in a reciprocating manner between the first current and the second current, wherein whenthe actual openness of the fuel gas proportional valve is the first openness, the corresponding current levels off to a third current; the first current is the current when the fuel gas proportional valve is opened to the first openness; the second current is the current the fuel gas proportional valve is closed to the first openness after magnetic hysteresis; and the second current is smaller than the third current which is smaller than the first current. Gas is input stably by way of changing the current of the fuel gas proportional valve.
Description
technical field [0001] The present invention relates to the technical field of gas heating equipment manufacturing, in particular, to a control method of gas heating equipment, a control method of gas heating equipment, a gas heating equipment, a computer device and a computer-readable storage medium. Background technique [0002] Gas heating equipment has been widely used because of its characteristics of instant heating. The gas proportional valve of gas heating equipment includes an electromagnetic coil. When the gas heating equipment is working, when the electromagnetic coil of the gas proportional valve is magnetized to a saturated state, at this time, even if the magnetic field is removed, the magnetic induction of the electromagnetic coil will not follow the original path Return, but decrease along a curve slightly higher than the original path, that is, hysteresis occurs, the existence of hysteresis makes the opening angle of the gas proportional valve not open or cl...
