Analyze the working principle of smart home

The emergence of smart homes has changed the way people live. Each smart home system works according to certain principles. This article will introduce the working principle of smart homes.

The so-called smart home is in the middle of the house, with appliances and other equipment as the main control objects, and using wiring, network technology and security and other technologies to control, providing a more secure, intelligent and particularly comfortable an integrated network platform.

The working principle of the smart home is wireless network technology, which connects the various home settings to the terminal, and then uses this terminal to realize intelligent operations; that is, to accept various types of sensing signals through various types of sensing devices and trigger The control command or the person's conscious remote control manually triggers the corresponding launching smart device to retract the control command.

Through various types of sensing devices, all kinds of sensing signals are accepted, and control commands are triggered or the conscious control of the person and the corresponding launching type smart devices are manually triggered to recover the control commands.

For example, the temperature and humidity sensor collects temperature and humidity data in the room and sets the triggering requirements for temperature and humidity changes according to requirements. When the temperature or humidity reaches the preset triggering requirement, the control command is linked and retracted. When the temperature is high, the air conditioning starts cooling. When the temperature is low, the air conditioner starts heating.

If the brightness sensor is installed, the preset light is actively closed when the indoor light is bright, and the preset light is automatically turned on when the indoor light is not bright enough. If a human body sensor is installed, when a person is in the armed state, a telephone alarm is triggered immediately when someone is active. When the person is not armed, the person is sensed, and a preset light is actively turned on. When no person is detected, the light is actively closed.

After the smart panel receives all kinds of control commands, it analyzes and decodes, drives the corresponding strong electric drive circuit, turns on or off the light control return road, and the control is completed; the control of electric equipment, curtains and other equipment is also the same. The digital curtain switch, after receiving the control command, immediately drives the corresponding circuit of the electric curtain motor to be turned on or off, so that the control of the curtain is switched; air conditioners, televisions, DVDs, etc., are sensed by the human body through the ceiling The device is completed, the body sensor receives the control signal, and immediately forwards the control signal to the corresponding infrared instruction, such as controlling the infrared control command of the DVD player, such as switching, playing and suspending.

With regard to the completion of the security alarm function, when the digital security module receives the control command, it will turn into a corresponding voice signal and dial the preset telephone number alarm. Regarding the control intelligence of the background music, as well, when the digital video center of gravity receives the control command, it immediately switches the external playback source circuit and starts playing the sound source.

Smart home brings a wide range of information sharing and safe, comfortable and convenient living environment, so that smart home into millions of households.
