Multi-key wake-up circuit and method for hand controller

Abstract

The invention provides a multi-key wake-up circuit and method for a hand controller, and belongs to the field of hand controllers. The multi-key wake-up circuit comprises a single-chip microcomputer, a matrix type key circuit and a single-chip microcomputer wake-up circuit, wherein the matrix type key circuit comprises a main circuit and a key circuit, the single-chip microcomputer wake-up circuit comprises a PNP triode Q1, the PNP triode Q1 is used as a switch to control connection and disconnection between a battery and the single-chip microcomputer, the matrix type key circuit is connected with the PNP triode Q1, when a key in the key circuit is pressed down, the matrix type key circuit controls the PNP triode Q1 to be switched on, and then the battery and the single-chip microcomputer are controlled to be switched on to wake up the single-chip microcomputer. The circuit has the advantages that by the adoption of the structure, wire cores can be reduced, the machining cost can be reduced, the single-chip microcomputer can be controlled to wake up by pressing the key. According to the invention, the circuit is used for waking up the single-chip microcomputer in a hand controller by the key.

Description

【Technical field】 [0001] The invention relates to a multi-button wake-up circuit and method for a hand controller, belonging to the field of hand controllers. 【Background technique】 [0002] Usually, lift tables, kitchen islands, folding beds and other equipment are equipped with hand controllers. There are multiple buttons on the hand controller for different function control. Usually, one button corresponds to one hand controller wire core. When multiple buttons are set, the hand controller has more wire cores, which leads to a complicated structure of the hand controller and higher processing costs. [0003] In order to reduce the number of wire cores of the hand controller, a determinant matrix circuit is usually used to connect the wire cores, so that the wire cores can be reduced. For example, M wires and N wires are used to form an M*N matrix, and the buttons are located at the intersection of the M*N matrix. , at this time, the number of wire cores is M+N, and the n...

[0002] Usually, lift tables, kitchen islands, folding beds and other equipment are equipped with hand controllers. There are multiple buttons on the hand controller for different function control. Usually, one button corresponds to one hand controller wire core. When multiple buttons are set, the hand controller has more wire cores, resulting in a complex structure of the hand controller and higher processing costs

[0003] In order to reduce the number of wire cores of the hand controller, a determinant matrix circuit is usually used to connect the wire cores, so that the wire cores can be reduced. For example, M wires and N wires are used to form an M*N matrix, and the buttons are located at the intersection of the M*N matrix. , at this time, the number of wire cores is M+N, and the number of buttons is M*N, so that the number of buttons can be reduced. However, with this matrix, the number of wire cores is still large, and the processing cost is still high.
