Description

Add-on wall switch remote control

technical field

The invention relates to an intelligent switch, in particular to an additional wall switch remote control device.

Background technique

According to statistics from relevant departments, my country's lighting electricity consumption accounts for about 12% of my country's total electricity consumption, which is the main component of building energy consumption. However, in lighting electricity, a considerable part of the electricity is wasted, especially in some large buildings (such as teaching buildings, office buildings, etc.), the waste of lighting electricity energy consumption is serious. The waste of lighting electricity is mainly determined by people's behavior habits: for lighting switches, most people have the habit of turning them on when they come, but they lack the behavior of turning them off as they go. In order to reduce the energy consumption of large buildings, the current common method is to arrange patrol personnel to regularly check one by one and turn off unnecessary lighting equipment.

In order to achieve the goal of "not only responding to the concept of green development, but also reducing human waste", technically reducing lighting energy consumption is an ideal way to save energy for large buildings. Among many technologies, smart home-related technologies are currently the most popular concept.
