Capacitance controller, control method and device

Abstract

The invention provides a capacitance controller, a control method and a control device. The capacitance controller comprises a capacitance detection chip, a processor, and a plurality of electrodes which are connected to the capacitance detection chip, wherein the plurality of electrodes form an electrode structure; the capacitance detection chip is used for detecting a capacitance value of each electrode; and the processor is connected with the capacitance detection chip and is used for controlling controlled equipment according to an accumulated sum of the capacitance values of the electrode at each boundary in the electrode structure. According to the capacitance controller, the control method and the control device, the technical problem that the required area is too large in an existing non-contact type gesture is solved, and the technical effect that the capacitance and non-contact type gesture identification is realized in a small area is achieved.

Description

technical field [0001] The invention relates to the technical field of electric appliance control, in particular to a capacitor controller, a control method and a device. Background technique [0002] With the continuous development of touch screen and automatic control technology, more and more devices are controlled by contact gesture control or non-contact gesture control. [0003] Currently, solutions for detecting non-contact gestures through capacitance changes generally recognize the user's gestures through changes in two independent electrodes. However, because the larger the capacitive detection electrode is, the farther the detection distance will be. If it is desired to detect multiple user gestures, electrodes with a larger area are required, which inevitably requires a larger space. [0004] How to realize capacitive non-contact gesture recognition in a small area has not yet proposed an effective solution. Contents of the invention [0005] Embodiments of t...
