The smart switch has had a history of more than ten years ago. The first ten years were basically tepid. However, with the development of science and technology, the popularity of smart phones and smart homes, smart switches have gradually had its market, gradually Consumer acceptance and acceptance. The intelligent switch has functions such as one-key operation and remote operation, and at the same time it is convenient to increase the safety of household electricity. Many people asked, what kind of technology is the "high-tech" of smart switches. Here we will introduce the technology of smart switches.
Intelligent switch technology analysis
1. Power line carrier control
The power line is used to transmit the signal. The switch needs to set the encoder and it will be interfered by the power line clutter, making the work very unstable and often causing the switch to lose control. The price is high, there are many additional equipment (such as wave traps, filters, etc.). Advantages: Cheap and easy to accept.
2, wireless RF control
The radio frequency signal is used to transmit signals. The switch is often interfered by radio waves, making the frequency stable and easy to lose control. The operation is very tedious and the price is very high. Such switches need to add a zero line to achieve multiple control and mutual control. Effect. Advantages: Cheap, affordable for the general public.
3, bus control
Fieldbus is used to transmit signals. Bus panels are connected through fieldbus to realize communication and control signal transmission. Its stability and anti-jamming ability are relatively strong. The earliest bus uses a centralized bus structure to concentrate all the wires. On the central control gateway or controller, and then from this location to the signal line to the location of each switch, so that the resulting wiring system is relatively poor security, the central controller is paralyzed, will affect the entire operation. The advantage of distributed fieldbus system: good security, not because of a point of failure and affect the operation of other points, stability and strong anti-interference ability, the signal to go through a dedicated signal line transmission, to achieve communication between switches and switches . But with the traditional wiring methods need to change. Each position of the smart panel can achieve multi-point control, total control, group control, point-to-point control and other functions.
4, single fire control
Is a kind of wireless communication similar to GSM technology, built-in transmitter and receiver module, single FireWire input, wiring method is the same as the traditional switch, easy to install. Disadvantages: Network control switch operation cannot be achieved.
Smart switches have human body sensor switches, electronic dimming switches, electronic speed control switches, electronic time switches, and other smart switches. In recent years, major changes have taken place in the home life. Many home appliances have entered people's lives, and controlling them is a simple mechanical switch. Although the switch is small, it has a great influence. The above content is compiled and edited by Zhijia.com.

With the improvement of people's quality of life, people's lifestyles have also become varied. Different kinds of recreational products are starting to appear in people's lives, such as electronic cigarettes. The emergence of e-cigarettes represents a part of young people's thinking and means that electronic products are beginning to show a trend towards diversity.
simply replace the pods. The Pod system uses an integrated pod rather than a tank for higher nicotine strength and provides low power traction. the Pod system is rechargeable and has a longer life and higher battery capacity than disposable electronic cigarettes.
Our company Pod system has a built-in 380mAh battery and a USB charging port on the bottom. In comparison, the Pod system has a built-in battery of only 180mAh, but the Pod system charges much faster.
Our electronic cigarettes are of rechargeable construction. The first time you use the charger to charge, it is recommended to use up the remaining power before filling up, this is to ensure the performance of the battery.
