Whole-house smart home system wiring method

Whole-house smart home system wiring method, modern smart home systems are often designed according to the specific situation and actual needs of a family. , every family is not exactly the same. So here’s how to wire a whole-house smart home system. Whole-house smart home system wiring method 1

Whole-house smart home system wiring method

1. Centralized control technology

Smart home systems that adopt centralized control methods, It is mainly constructed through a system host with a microcontroller as the core. The central processing unit (CPU) is responsible for the signal processing of the system. The system motherboard integrates some peripheral interface units, including security alarms, telephone modules, and control loop input/output (I/ 0) Modules and other circuits.

This type of centralized control system motherboard generally has 8 channels of lighting and electrical control loops, 8 channels of alarm signal input, 3-4 channels of meter reading signal access, etc. Due to the limitation of system capacity, once the system is installed, it is difficult to expand and add control loops.

Due to the star wiring method of this type of product, all security alarm probes, lights and electrical control circuits must be connected to the main control box. Compared with traditional indoor wiring, the wiring length is increased and the wiring is more complicated. There are many such products on the market currently.

2. Fieldbus technology

The fieldbus control system uses the system bus to realize the networking and signal transmission of home lighting, electrical appliances and alarm systems, using With decentralized on-site control technology, each functional module in the control network only needs to be connected to the bus nearby, making wiring more convenient.

Generally speaking, fieldbus products support any topological wiring method, that is, they support star and ring structure wiring methods. The wiring of strong currents such as lighting circuits and socket circuits is completely consistent with traditional wiring methods. "One light with multiple controls" is relatively common in home applications. In the past, it was generally implemented using "double" or "quadruple" switches.

The wiring is complex and the wiring cost is high. If controlled through the bus, there is no need to add additional wiring. It is a fully distributed intelligent control network technology. Its product modules have two-way communication capabilities, as well as interoperability and interchangeability, and its control components can be programmed.

Typical bus technology adopts a twisted pair bus structure. Each network node can obtain power supply (24V/DC) from the bus, and can also realize interconnection between nodes without polarity and topological logic restrictions through the same bus. And communication, the signal transmission rate and system capacity are 10KBPS and 4G respectively. Whole-house smart home system wiring method 2

It also realizes interconnection and communication between nodes without polarity and topological logic restrictions through the same bus. The signal transmission rate is as high as The system capacity is 10KBPS and 4G respectively.

The fieldbus control system adopts a bus-type structure and is mainly composed of three basic parts: power supply, twisted pair and functional module. Each functional module is connected in series on a twisted pair, and the mutual connections are regardless of polarity. Bus control system products can be divided into many categories in terms of function. The following will briefly introduce the commonly used ones:

(1) Basic control products, mainly including bus power supply, wireless remote control interface, and telephone remote control interface , computer control interface, Ethernet (TCP/IP) interface, security control and security alarm interface, etc. These products are the basis of the bus control system and also provide an interface platform for other bus control products.

(2) Lighting control products, represented by light-touch electronic switches/regulators. One feature of this type of product is that its appearance size is similar to that of a normal switch. It can directly replace the original switch to realize the intelligent transformation of the lighting system. It can be dimmed or controlled remotely, and can also be used to generate different light combinations. To meet different lighting needs. In the event that a particular electronic switch fails, only the part to which the switch is connected will be affected. Even if there is no spare product, the original switch can be replaced to restore the original function and realize manual operation.

(3) Electrical control products, these products are the controllable sockets mentioned earlier. Similar to electronic switches and dimmers, this type of product can also achieve intelligent transformation of electrical control by directly replacing the original socket. By connecting the power of electric appliances such as rice cookers, water heaters, and washing machines to the socket, users can control these appliances through electronic switches, remote controls, or telephones, which is very convenient. The controllable socket has two operating modes: automatic and manual. In case of system failure, it can also be operated manually.

(4) Infrared control products. These products are mainly used to control air conditioners, TVs, DVD players and other home appliances with infrared remote controls. They have the learning and memory functions of infrared signals and can Through the equipment connected to the control bus (including control panel, timing, remote control, telephone, Internet, etc.), the operations of turning on, off, mode, temperature, etc. of the air conditioner, as well as turning on/off and volume adjustment of TVs and DVDs are realized. , channel selection, play, stop and other operations.

(5) Security control products, which mainly include human body infrared sensors, gas leak sensors, smoke and fire sensors, three-meter automatic meter reading and visual intercom systems, etc. The installation and use of these products are simpler than other products because they have bus compatibility marks and can be directly connected to the bus, and can use the telephone remote control/IP interface and other alarm interfaces in the basic system to achieve remote alarm. In addition, through the security control interface in the basic system, ordinary sensors can also be used in the bus system.

At present, wireless smart home systems mainly include power carrier and remote control switch.

There are two types of remote control switches: wireless RF remote control technology and infrared IR remote control technology. Remote control switches are mainly products of some traditional ordinary electrical product manufacturers. In fact, remote control switches only add remote control functions on the basis of traditional switches. Some products also add timing control to the remote control. However, due to its single function, it should not be used Count as smart home products.

High-frequency power carrier home control system is a representative product for wireless technology applications. Power carrier technology uses 220V power lines to transmit high-frequency signals from the transmitter to the receiver to achieve intelligent control.

The high-frequency signal transmission technology loads the 120Khz coded signal onto the 50Hz power line. The transmitting device sends the high-frequency signal to the receiver, and each receiving device has an address code preset. The address code is composed of room code (A-P) and unit code (1-16), with a maximum of 256 combinations. Therefore, no additional wiring is required when using this system, which is also the biggest advantage of this system.

Power carrier technology was first used in the United States. This product is mainly used in the renovation of old houses in the United States, while in China, this issue is only considered when buying a new house or renovating an old house.

If the house is decorated inside the wall, it will be somewhat uncoordinated if a high-frequency functional module is added to the switch plug. Some technical limitations of high frequency have become excuses for criticism. For example, the response speed is slow (in a 50Hz power supply system, it takes 0.62 seconds to transmit an instruction), the anti-interference performance is poor (this is caused by the signal carrier being transmitted in the power line, and this problem is more serious in our country), etc. Substantial problems brought about by the promotion and application of carrier systems in our country.
