Abstract

The invention discloses a special low-delay intelligent wall switch, and aims to solve the problems that an intelligent wall switch is high in delay and large in wireless control difficulty in the prior art. The special low-delay intelligent wall switch comprises a first current generating circuit, a second current generating circuit, a transconductance copying circuit, a wireless signal transceiver, a wireless control signal generator and a relay switch. A current is converted into a voltage through a field-effect transistor, and the conversion can be achieved without a resistor, so that theoutput of a transconductance voltage with low relative delay and high linearity is achieved; then the periodic opening and closing of the relay switch are periodically controlled through the transconductance voltage, and therefore an intelligent switching mode is realized by utilizing a digital circuit; meanwhile, a switch signal is transmitted to the relay switch through the wireless control signal generator, while, the control of external equipment is also received by the wireless control signal generator, so that long-range use and short-range use of the special wall switch are achieved; and the special low-delay intelligent wall switch is suitable for the aspect of professional intelligent wall switches.

Description

technical field [0001] The invention relates to the field of intelligent switches, in particular to a low-delay intelligent wall special switch. Background technique [0002] Smart switches develop with the continuous development of smart homes, and are mainly used to remotely control the opening and closing of other devices. Smart switches usually provide a stable low voltage to electrical appliances. The special wall switch is mainly set on the wall, which is different from other types of switches. Because the existence of the wall may prevent the signal from being transmitted, it is difficult to realize remote wireless control of the wall switch, and the delay problem is often difficult to solve. How to solve the delay and wireless control problems of the wall switch is of great significance for expanding the use of the wall switch. Contents of the invention [0003] The object of the present invention is to provide a low-delay special switch for an intelligent wall ...
