Free pairing type wireless remote control switch

Abstract

The invention provides a free pairing type wireless remote control switch and belongs to the technical field of applied electronics, aiming at solving the problems that a traditional wireless remote control switch that remote code crosstalk hidden dangers exist and free pairing between remote control and a controlled electrical appliance cannot be realized. The free pairing type wireless remote control switch mainly comprises a remote controller and at least one switching node, wherein the remote controller comprises a power supply switching module A, a remote controller data processing moduleand a wireless transmitting module; the switching node comprises a power supply switching module B, a wireless receiving module, a switching node data processing module and an electrical appliance power line wiring opening. According to the free pairing type wireless remote control switch, one remote controller has one code so that the problem of a traditional remote controller has the code crosstalk hidden dangers is solved; furthermore, free pairing between a remote controller key and the switching node is realized; the free pairing type wireless remote control switch has very strong practicability, can be widely applied to various fields including homes, shopping malls, hotels, factories and the like and has high economic value.

Description

technical field [0001] The invention belongs to the technical field of applied electronics, and in particular relates to a free pairing radio remote control switch. Background technique [0002] The radio remote control switch is a new type of intelligent switch, which is widely used in various fields of life because of its portability and ease of use. However, in the actual use process, it is found that the existing radio remote control switch is not perfect, and has the following defects: 1. The total number of remote control key codes is small, and the codes are likely to be the same, and there is a hidden danger of remote control serial codes; most of the existing remote controls use PT2262 chips Code, the total number of codes generated by this coding method is only a few thousand, and it is inevitable that there will be remote controllers with the same code; 2. The buttons of the remote controller are bound to the switch nodes one by one. If a button is damaged, the c...

The buttons of the remote controller are bound to the switch nodes one by one. If a button is damaged, the corresponding switch node cannot be remotely controlled, and the remote control must be replaced; 3. Although there are remote control products on the market that can control several electrical appliances at the same time, the controlled electrical appliances are preset by the manufacturer. Unable to change by yourself, the choice is limited, the quantity is also limited, and it cannot be paired freely
