The traditional switch evolved from the initial pull and pull rope switches to rocker switches, and smart switches are now becoming popular. It can connect mobile APP, remote control of all light switches, safe and convenient. So what kinds of smart switches are there and how can they be used in our lives? 1. Power line carrier switch : The power line carrier switch uses power line transmission to send information. The switch needs to set the codec, which will be interfered by power line clutter, making it very unstable and often causing the switch to lose control. Many additional equipment are expensive, (for example, there are many types of switches, and they also require wave traps, filters, etc.) A set of system prices: 20,000-50,000 yuan 2. Wireless switch: The wireless switch uses RF mode (433,315 free channels) to transmit information. The switch will often be interfered by radio waves, making its frequency unstable and losing control, and each product needs to set the codec. The operation is very tedious, each product after sale also requires a special set of code number, the more the number, the more troublesome maintenance. In this room, it is impossible to see the display status of the lights outside the room. Although it can be controlled through the remote control wall, it cannot be determined whether it is turned off. The more lights, the more and more remote control buttons bring more complex (for example, a family has 50 lights, remote control must have 50 keys). Infinite life is not very long, after-sales rate is relatively high (at present domestic wireless technology frequency is the higher the better, this will often affect the product's life, there is a certain foreign wireless frequency limit). The additional equipment has a lot of price points (for example, there are many kinds of switches, and it needs a receiving module, a modem, a centralized controller, etc.). (The excessive wireless frequency is not suitable for a floor or a multi-floor installation. The more installations, the greater the interference.) A set of systems, between 5000-50,000. 3, bus control: is the use of fieldbus to transmit signals, through the field bus to connect the bus panel to achieve communication and control signal transmission, its stability and anti-interference ability is relatively strong, the earliest bus is a centralized bus structure, all The wires are all centralized on a central control gateway or controller, and then the signal line is located from this location to the location of each switch. This leads to poor wiring system security and the central controller is paralyzed, which 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 FireWire Control: It is a kind of wireless communication similar to GSM technology. It has built-in transmitting and receiving modules and single fire input. The wiring method is the same as the traditional switch and easy to install. Disadvantages: Network control switch operation cannot be achieved. Compared with ordinary switches, smart switches are more powerful, convenient to use, energy-saving, and environmentally friendly, improving our quality of life. And it is easy to install, no need to re-wiring, can directly replace the original switch, ordinary family at any time to replace the installation switch will not affect the original decoration style.
