With the development of society, the continuous advancement of science and technology, and the concerted efforts of experts, many high-tech intelligent products have emerged in science fiction movies. For example, a smart home server, but not all people are very familiar with it, then let Xiaobian introduce it to everyone.
What is a smart home server?
The smart home server is the brain of a smart home. It communicates with the outside world through a network and a telephone line, and is connected to various smart home devices through various cables, communicates with people through various human-machine interfaces, and can follow human instructions and software. The set program controls the home equipment.
The home intelligence system carries out centralized or off-site monitoring, control, and family affairs management, and maintains harmony and coordination between these home facilities and the residential environment. These functions can be achieved through the home server. So home server is the core of smart home, and some people compare it to the brain of adults. It can be seen that the home server plays an important role in smart homes.
What is the smart home server?
According to the function of the smart home system, the system components of the home server can be divided into home server hosts; home device control networks; home video surveillance systems and home security alarms;
Home Server Host The home server host is mainly composed of a central processor and various communication modules. The home device control network home device intelligent control unit is composed of a lighting control module, an air conditioning control module, and a household appliance control module.
The home communication network unit consists of a telephone communication module, a computer internet module, and a CATV module. Home video surveillance systems and home security alarms. The home security defense unit consists of a fire alarm module, a gas leakage alarm module, a burglar alarm module, an access control intercom, an emergency call for help module, and a camera monitoring module. Family four-table remote copy system. The four-table remote copying system consists of meters, water meters, gas meters, heat meters and other metering meters and meter, water meters, and gas meter data acquisition modules.
I believe that through understanding the above content, we will have a better understanding of the smart home server, in the decoration of new homes, you can have a bigger and broader choice for smart home server market.

Semiconductor Fuse and Ferrite
Fuse refers to an electric appliance that, when the current exceeds the specified value, melts the fuse and disconnects the circuit with the heat generated by itself.When the current exceeds the specified value for a period of time, the fuse melts and disconnects the circuit with the heat generated by the fuse itself.A current protector made from this principle.The fuse is widely used in high and low voltage power distribution system and control system as well as power equipment.
Ferrite is a metal oxide with ferrous magnetism.As far as electrical properties are concerned, the resistivity of ferrite is much larger than that of single metal or alloy magnetic materials, and it has higher dielectric properties.Ferrite magnetic energy also shows high permeability at high frequencies.As a result, ferrite has become a non-metallic magnetic material widely used in the field of high frequency and weak current.Due to the low ferrite magnetic energy stored in the unit volume, saturated magnetic induction strength (Bs) and low (usually only pure iron 1/3 ~ 1/5), and thus limits its higher requirements in the low-frequency magnetic energy density in the field of high voltage and high power applications.
