As we all know, the smart home system is now a popular trend in the society. In order to better improve people's life needs, the smart home system can meet the basic needs of life through a series of changes, thus effectively improving the happiness of home. Feeling, make your home more attractive! First, the scope of intelligent system design The home design system includes: intelligent lighting, temperature, music, home theater, doors and windows, electrical appliances, watering flowers, pet feeding, running water, gas, etc. Control methods include: remote computers, mobile phones, control panels, etc. All of the above systems can operate independently or in conjunction with other systems, and integrate into a unified whole and respond to each other to achieve a true sense of smart home. Second, the principle of intelligent system design Convenient for user operation, functional and practical, beautiful appearance, can reflect the high-class fashion life taste. It is simple, highly human, and focuses on health and entertainment. Third, the control area Living room: Through the control of living room lighting, audio and video, air conditioning, and television, create a comfortable living space. Through the intelligent scene control interface, the one-key scene control of the light is realized, and the light environment required for meeting, eating, video, and full-off in different time periods is automatically realized. Rooms, gardens, study rooms, children's rooms, etc.: There are more than a dozen lights in the house. Each room has different lighting and electrical requirements, and the lighting requirements are different. Use a mobile phone or mobile panel to easily complete a variety of lighting scenes. Various modes, one button can control the lighting, air conditioning TV. If you press "Go Home Mode", the light will turn on, the curtains will open, the air conditioner will turn on, and the TV will turn on. When you are away from home, press "Full Off Mode" to automatically turn off all lights. There is a manual switch on the controller, which can be turned on or off manually in the event of a fault. Custom scene mode, one-click switching The physical structure of L. SYV is 100% polyethylene insulation; Sywv# for physical foam polyethylene insulated Cable, foaming rate of 70-80%; L. Due to the dielectric loss, the attenuation of SYV solid cable is significantly greater than that of SYWV physical foam cable; Among the commonly used engineering cables, the physical foam cable is still the best transmission performance, the lowest price of the cable, in video, radio frequency, microwave and other bands are so. The test data given by the manufacturer also shows this; L) Library coaxial cable can be used for DC, RF and microwave frequency bands. Differentiating cables by "RF"/" video "is not only insufficient, but also misleading: it seems that solid cables must or can only be selected for video transmission. ; From an engineering perspective, it is more practical to distinguish between "solid" and "foam" cable types; L The characteristic difference between high braided (128) and low braided (64) cables: Yi Aiyi laboratory experimental research shows that in the following frequency band of 200 KHZ, the "low resistance" of high braided cables plays an important role in the shielding layer, so the low frequency transmission attenuation is less than that of low braided cables. However, in the video, RF and microwave frequencies above 200-300 KHZ, the high braided cable has lost the advantage of "low resistance" due to the "high frequency skin effect", so the two high frequency attenuation cables are basically the same.
