Problems solved by technology

The use of batteries can certainly solve the problem of power supply for smart switches, but there is the trouble of needing to replace batteries regularly
The technologies used for single live wire power extraction are different, but in the final analysis, the wireless intelligent control circuit is connected in series in the controlled load circuit to achieve power acquisition. This method brings hidden dangers in electricity safety and keeps the load In the micro-current working state, the load is abnormal and affects its service life; since there are two working states for the single live wire, especially when the load is turned on, in order not to affect the load work while being able to obtain enough current, there is often a minimum possible The requirements for power control make it impossible to control low-power lighting, which will undoubtedly become a bottleneck for LED lighting control that will become mainstream in the future
In the scheme where the ordinary switch is connected in series with the wireless intelligent module, when the ordinary switch is closed, the normal power supply of the intelligent module is provided, and at the same time, a power-on reset signal is provided to the wireless intelligent control module to control the lighting to be turned on, and when the ordinary switch is turned off, all circuits are cut off Power supply, although this method can retain all the functions of the ordinary wall switch, it also partially solves the power supply problem of the intelligent control module, but because the power supply of the wireless intelligent control module is cut off when the ordinary switch is off, the switch is off. The wireless intelligent control function fails, which brings inconvenience to the actual use
Related technologies can refer to patents such as CN 102186295 A, etc. It can be seen that the implementation of wireless intelligent control under the actual situation of single live wire wiring that is currently widespread still has many limiting factors, and it is not a fundamental solution to single live wire control.

Abstract

According to a control method, a scheme for controlling a switch through a single live wire is achieved through a single-pole double-throw change-over switch (31), a power supply and electricity storage circuit (32), a single-live-wire control module (33), a wireless intelligent control module (34), an electronic switch (35), an illumination load (36) and the like. The power supply and electricity storage circuit (32) is connected to the access end of the illumination load and supplies power through a null line connected to the illumination load (36) and the live wire communicated with the single-pole double-throw change-over switch (31). When the single-pole double-throw change-over switch (31) is operated to conduct change-over, the live wire can be instantly cut off within a short time interval due to the voltage, the single-live-wire control module (33) picks up the signal generated when the live wire is instantly cut off and outputs the signal to the electronic switch (35) after processing the signal. The illumination load (36) is controlled through the electronic switch. Power can be normally supplied to the wireless intelligent control module through the power supply and electricity storage circuit (32), and meanwhile the wireless intelligent control is achieved.

Description

technical field [0001] The invention relates to a method for controlling an intelligent switch by a single fire wire in the field of intelligent home control. Background technique [0002] At present, the development of technology in the field of intelligent control has promoted the popularization of smart home products, and the intelligent control of lighting switches has always been the main control object in the field of intelligent control. With the development of wireless transmission technology, wireless intelligent control products can be realized without destroying the original decoration, and have a very broad market prospect in the field of smart home. However, due to people's living habits and the existence of a large number of renovated houses, the existing wall switch control method needs to be retained. In order to achieve wireless intelligent control while retaining the functions of existing wall switches, a wireless intelligent control module that can be con...
