Looking from the cabling technology Smart Home Development - Smart Home - Security Industry
With the continuous development of smart home industry, many manufacturers began to put human, material and funds to develop different types of intelligent home
Product . Product and technology road began to divide, showing diverse trends.
1, an overview of intelligent home
What is a smart home it? At present, the smart home can be defined as a process or a system, using advanced computer technology, network communication technology, integrated wiring technology, and home life of the various subsystems, including the
Home Appliances Control and security guard, remote meter reading, information services and video intercom functions, together organically, through integrated management, make home life more comfortable, safe and effective.
Second, the product wiring Introduction Now Market The smart home products, classified according to wiring methods, mainly centralized control, field bus, three kinds of wireless technology. Wireless Control System which can be divided into infrared communication, radio frequency wireless communications, power line carrier communication categories. Here are the basic concepts of several control techniques.
1, centralized control technology Centralized control mode the smart home system, mainly through a single chip computer system
Host To build the center processing unit (CPU) for signal processing systems, the system integrates a number of external board
Interface unit , Including the security alarm, telephone module, the control loop input / output (I / 0) module circuit.
Such centralized control system motherboard with 8 general lighting, electrical control circuit, 8 alarm inputs, 3? 4-way meter reading signal access. As the system capacity constraints, once the system installed, the extension to increase control loop more difficult.
These products thanks to star wiring, all security alarm
Probe , Lighting and electrical control circuit must be connected to the master box, with the traditional interior layout, an increase of the length of cabling, wiring more complicated. More such products currently on the market.
2, field bus technology Fieldbus control system is achieved through the system bus home lighting, electrical and alarm system, networking and signal transmission, field control technology with distributed control function modules within the network access bus can only nearby, more wiring convenience.
General, fieldbus products support arbitrary topology wiring, which is to support the ring structure and star alignment method. Lighting circuits, socket electrical wiring circuit so strong and consistent conventional wiring. "A light multi-control", in the home are quite common in previous years, a "double", "quadruple" switch to achieve an alignment complexity and wiring costs. If the way through the bus control is completely without additional wiring. Is a fully distributed intelligent control network technology, its products have a two-way module
Communicate Capacity, and interoperability and interchangeability, the control unit can be programmed. A typical bus technology uses twisted pair bus architecture, the network node can be powered from the bus (24V/DC), also achieved by the same bus between nodes polarity, no restrictions on the interconnection topology logic and communication, signal transmission rate and system capacity were 10KBPS and 4G.
Fieldbus control system uses bus-like structure, mainly by the power supply, twisted pair and functional modules composed of three basic parts. Each function module is to link the twisted pair, the mutual connection, regardless of polarity. Bus control system products from the function can be divided into many categories, following a brief introduction of several commonly used:
(1) basic control products, including bus power supply, wireless remote control interface, telephone remote control interface, computer control interface, Ethernet (TCP / IP) interfaces, security control and security alarm interfaces, these products are Bus control system is based, but also for other products to provide a bus control interface platform.
(2) lighting control products to touch-type electronic switch / regulator represented. A special feature of this type of product is its size and appearance similar to normal switches can directly replace the original switch can be modified to achieve the intelligent lighting system, dimming can also be remote, but can be used to produce different lighting combinations to meet the needs of different lighting. In case of individual electronic switch malfunction, which affect only the switch is also connected to that part, even if no alternate products may be back in the switch will return to its original function, achieved manually.
(3) electrical control products, such products that are mentioned earlier, the control socket. And electronic switches, dimmers similar, these products can also be a direct replacement for the original outlet to achieve the transformation of the intelligent electrical control. To rice cookers, water heaters, washing machines and other electrical power connection in the socket, users can electronically switch, remote control or phone to control these appliances, very convenient. The controlled sockets with automatic and manual operation mode, in case of system failure, also can use to manually operate.
