Summary of home Integrated Wiring System experience

It is very important to understand the Integrated Home wiring system, especially the current rapid development of intelligent systems. So I have studied the knowledge of Integrated Home wiring systems and will share it with you here, I hope it will be useful to you.

1. Concept of Smart Home Integrated Wiring
Smart Home is the first concept in the United States. It generally refers to various information-related communication devices, household appliances, and Home security devices in the family, connect to a Smart Home System (home Controller) through the home bus technology to achieve monitoring, control, and management of household affairs, and maintain the harmony and coordination between these home facilities and the residential environment.

2. Implementation of the Smart Home System
2.1 main transmission modes
Smart Home systems can be implemented through two transmission channels: wireless transmission and wired transmission. Home Radio Frequency and Bluetooth are two main types of wireless transmission technologies. Three wired transmission methods are available: the Integrated Home cabling system protocol, which is implemented by the Integrated Home cabling system. The leased line in the home is used, and the HomePNAHome Phoneline Networking Alliance technology is used ); the Power Line Carrier Technology Powerline Carrier Technology is used for power cord transmission in the home ). However, from the perspective of the existing technology level, wireless technology can only be said to be a development trend, and most systems still use wired technology. The following describes several major wired technologies:
A. Integrated Home wiring system: it is currently the most widely used but also the most cumbersome technology;

B. HomePNA technology: the transmission rate of Home PNA Specification 1.0 on a universal telephone line is 1 Mbps, and the rate of Home PNA Specification 2.0 is 10 Mbps. HomePNA allows 25 PCs, peripherals, and other network devices to connect to the Internet. The maximum distance between devices is 500 feet. With products that comply with the HomePNA specifications, you can use existing telephone lines to connect your computer and other household devices, and make phone calls at the same time. The HomePNA specification is compatible with existing Internet access technologies. Its main applications include Internet access, data sharing and applications, as well as shared peripherals such as printers, scanners, modems, digital cameras, and storage devices. It can also play multiplayer games.

C. power Line Carrier Technology: Power Line Carrier System Powerline Carrier Stystem) is a method for transmitting information through a 120 V, 60Hz power distribution system in the home or equipment. It uses the X10 protocol. In the past, due to the large electrical noise and random noise transmitted using power cords, the application scope was very small. The power cord Transfer System of CEPCO solves this problem. In the United States, this technology is quite mature and has many application products.

2.2 Smart Home Integrated Wiring System
The Smart Home Integrated Wiring System should be designed according to the Integrated Wiring standard home wiring standard TIA/EIA 570-A), but its structure is relatively simple. There are several wiring solutions, one is NORDX/CDT's RUN (Residential Universal Network) Smart Home wiring system, the other is the In House system, an integrated Smart Home cabling system launched by ortrow.gov.cn ".

3. Composition of the Smart Home System
The Smart Home System consists of home network appliances, devices, and core components-home controllers.
Network appliances include portable laptop, network microwave oven, network refrigerator, network washing machine, network air conditioner, network water heater, network dishwasher, Network Camera, visual phone, network printer, network audio system, automatic curtain. Home controller is the core of smart home. In the system, each household appliance and device communicate with each other through the home controller. The Home Controller provides various service functions through the home bus system, and is connected to the external world outside the home.

4. functions implemented by the Smart Home System
Monitoring of household equipment;
Data collection and transmission of electric meters, water meters and gas meters;
Monitoring and modulation of air conditioners;
Monitoring and modulation of lighting equipment;
Home Security Prevention functions: Fire Prevention, gas-proof combustible gas leakage prevention, anti-theft alarm, security intercom, emergency call for rescue;

5. development space and direction of the Smart Home System
The Smart Home Integrated Wiring System was first developed in the United States and then transmitted to developed countries such as Europe and Japan. In the United States, smart home has a large proportion in the family, and some famous manufacturers such as IBM also have products in this area. In China, with the development of economy, people's pursuit of quality of life is also getting higher and higher. Shenzhen's Donghai garden, chuangshiji Binhai garden, Beijing's modern city and other residential areas are equipped with Smart Community systems. We believe that the smart home system will have more room for development in the future.

Due to the high cost and inconvenient Implementation of Wired facilities, the future trend of product development is moving towards mobile development. Therefore, smart home systems will also develop towards wireless.
