From the skill level, what types of smart switches can be divided into? Bus control, bus control is the use of fieldbus to transmit signals, and the bus panels are connected through fieldbus to complete communication and control signal transmission. Its stability and anti-disturbance ability are relatively strong. The wires will be combined with the control gateway or controller in the center, and then divide the signal line from this position to the position of each switch, so that the wiring system security is relatively poor, and the central controller is paralyzed, which will affect the entire operation.
The advantages of the distributed fieldbus system: good safety, no faults in one point will affect the operation of other points, strong stability and anti-disturbance ability, the signal is transmitted through a special signal line, and the switch and the switch communicate with each other . But the traditional wiring method needs to be changed. The intelligent panel in each direction can complete multiple functions such as multi-point control, master control, group control, and point-to-point control.
Radio frequency control, radio frequency control uses radio frequency methods to transmit signals. Switches are often disturbed by radio waves, making their frequency stable and easy to lose control. The operation is very cumbersome and the price is high. This type of switch needs to add a neutral line. In order to achieve the effect of multi-control and mutual control. Advantages: The price is cheap and easy for the masses to bear.
Power line carrier control. Power line carrier control uses power lines to transmit signals. The switch needs to be equipped with an encoder, which will be disturbed by power line clutter, making the operation very unstable and often causing the switch to lose control. The price is very high, and there are many additional equipment (such as wave traps, filters, etc.). Advantages: cheap and easy to afford. Single front control, single front control is a kind of wireless communication similar to GSM technology, built-in transmitting and receiving module, single front input, the wiring method is the same as the traditional switch, and the device is convenient. Disadvantages: unable to complete the network control switch operation.
