step 102, acquiring the static environment capacitance value of each touch key of the water heater control terminal.
Wherein the water heater control terminal may be, but is not limited to, a bath controller. In a specific example, each touch key of the water heater control terminal may be all touch keys on the water heater control terminal, or may be all touch keys in a to-be-monitored area or a designated area in the water heater control terminal, which is only a specific example, and may be flexibly set according to requirements in practical application, which is not limited herein.

wherein C is ΔN The target capacitance difference value of the touch key is the target capacitance difference value; c (C) cN The current capacitance value of the touch key; c'. bN The static environment capacitance value of the touch key is the static environment capacitance value of the touch key.
In one embodiment, the current capacitance value may be a current acquired capacitance value of the touch key, or may be obtained by processing the acquired capacitance value.

The foregoing is merely a specific example, and may be flexibly set according to requirements in practical applications, which is not limited herein.
In this embodiment, the water heater control terminal may acquire each acquired capacitance value of each touch key in the second preset acquisition period, and generate an acquired capacitance value array; according to the weighted value array, weighting recursive average filtering processing is carried out on the acquired capacitance value array, so that the current capacitance value of each touch key is obtained; the reliability of the current capacitance value of each touch key is guaranteed, and the accuracy of the touch information and the false touch prevention identification process of the water heater control terminal is improved.

When the target capacitance difference value corresponding to any touch key of the water heater control terminal is larger than the static environment capacitance threshold value, the water heater control terminal can determine the touch key corresponding to the target capacitance difference value belonging to the touch trigger capacitance interval, namely the target touch key, and generate touch information according to the target key.
In one embodiment, the minimum value of the touch trigger capacitance interval is a normal touch trigger capacitance threshold; the maximum value of the target trigger capacitance interval is the maximum trigger capacitance threshold; the normal trigger capacitance threshold is greater than the static ambient capacitance threshold. Therefore, the recognition accuracy of the target touch key is improved through the touch trigger capacitance interval determined by the normal touch trigger capacitance threshold and the maximum trigger capacitance threshold, and the accuracy of the touch information and the false touch prevention recognition process of the water heater control terminal is also improved.
In one embodiment, the step of generating touch information from the target touch key includes:
