Traditional switches, we generally refer to mechanical switches, representative products are wall switches. Wall switches and intelligent air openings do not see any drawbacks in the practical application of a single single control. If the disadvantages of the wall switch compared to the intelligent open, it is mainly reflected in the realization of multi-link interactive control. The effect and function of this multi-link interactive application level are difficult for traditional mechanical switches to do.
To understand why smart switches can achieve multi-link interactive control, let's first look at the structure of traditional switches and smart switches.
Traditional switches
You can see that this is a very simple circuit, about the knowledge of junior physics. The lamp is connected to the neutral line and the fire line of the alternating current respectively, and then a mechanical switch controls the opening and closing of the fire wire, thereby controlling the opening and closing of the lamp.
Smart switch
Compared with traditional switches, smart switches use relays and smart modules to replace the original mechanical switches, and the opening and closing of the lamp is controlled by relays. Relays open and close the circuit no differently than mechanical switches, but in order for smart switches to have electricity, we need to connect a zero wire. This kind of intelligent switch is called a zero-fire smart switch.
However, not all families are willing to take the bright line to pull an ugly zero line to the switch, so with the development of technology, there is a single-fire smart switch.
If the zero-fire version of the smart switch is connected in parallel on the circuit like other large and small appliances in the home, then the single-fire version of the smart switch is connected in series with the lamp:
But such a single fire switch has a very big drawback, that is, even if the relay is disconnected, the current flowing through the smart module will also pass through the lamp to form a loop, of course, when the current is small enough, and the power of the lamp is large enough, you can not detect any problems. But when the smart module is slightly more powerful, or you use a very small power LED light, the problem arises - the light will start to flash.
In order to solve this problem, it was later developed to put a capacitor on both ends of the lamp, so that the current can pass through the capacitor as much as possible:
Now we have a basic understanding of the structure of traditional switches and smart switches. Of course, this is just a few rough sketches, and the actual structure is much more complex than these.
We can find that no matter which wiring method, the smart switch has one more component called the "smart module" than the traditional switch.
This intelligent module can contain more things. Including hardware, dimming modules, voice modules, etc. for communication with smart hosts, different modules are set according to different application scenarios, so as to achieve different functions and multi-link interaction control between each other.
At present, compared with traditional switches, the functions that intelligent air-opening can achieve are:
1. Centralized control can realize the device when going out, or when guests come to the house, you can start the meeting or entertainment lighting scene with one key, without having to press the switch all the way.
2. Remote control This is also the main function of all smart home appliances at present, that is, through the mobile phone app to switch control of the device, which is also the basic part of the so-called "smart". Anywhere at home, you can turn on and off the lights wherever you need, which is especially practical for the elderly, pregnant women, and children. The room children can be air-conditioned, convenient and worry-free.
3. Timing control According to different times and events, the device can be set to automatically turn on or off. 4. The whole house controls every electrical appliance in your home that you can think of, even the curtains, which can be controlled by intelligent air opening, including electric fans, air purifiers, water dispensers, air conditioners and so on.
It can upgrade your home's traditional switches, dimming switches, curtain switches, and dual-control switches to wireless intelligent air-open, which can be remotely controlled through mobile phone APP, while also retaining the physical touch of the switch.
The most important thing is that there is no need to install a separate gateway, which saves a lot of hidden costs and increases the convenience of operation. The product is installed exactly like a normal switch socket without the need for additional wires. All the light brightness is set according to your preference, creating different atmospheres through different combinations of lights. At night, the function of turning off all switches with one key can not be more intimate ~ you can also use the light wake-up function in the morning. Imagine a fixed time every day, the curtains automatically open, the light of the room like the sunrise, slowly and softly brightening, so that you wake up naturally....how beautiful it should be.
Undoubtedly, intelligent open space has broad development prospects in the smart home industry. Ordinary switches will gradually be eliminated by the market is an irreversible fact, and with the slow development of the smart home industry, smart empty open want to fully popularize ordinary families also need to go through a buffer period, until it is fully accepted by the market, its advantages will become more and more powerful in the smart home industry.
