The Ideal Solution for ZigBee Electric Intelligent Curtain System

With the development and change of social and economic structure, family demographic structure and information technology, and the improvement of human requirements for the safety, comfort, and efficiency of the home environment, the demand for home intelligence has greatly increased. And more and more families require smart home products not only to meet some basic needs but also require smart home systems to be simple, convenient, and safe in terms of functional expansion, extension, and even services.

Introduction: Smart home system adopts technology

Although the concept of the smart home appeared very early and the market demand has always existed, the development of the smart home has not been widely applied and popularized for a long time due to the breakthrough of related technologies. The smart home technology that currently exists in the market is introduced as follows:

1. Wired Mode

In this way, all control signals must be connected by wire, and the number of signal lines on the controller side is scary. The shortcomings of the wired mode are very prominent: the wiring is complicated, the workload is large, the cost is high, the maintenance is difficult, and the networking is not easy. These shortcomings eventually lead to the fact that the wired smart home is only in the concept and pilot stage, and cannot be promoted on a large scale.

2. Wireless Mode

Wireless systems used in smart homes need to meet several characteristics: low power consumption, stability, easy expansion, and grid connection. As for the transmission speed, it is not the focus of such applications. There are currently several wireless methods that can be used for smart homes.

(1) Bluetooth

Bluetooth is a radio technology that supports short-range communication between devices (generally within 10m). The communication distance of this technology is too short, and it belongs to the point-to-point communication method, which is not suitable for the requirements of the smart home.

(2) Wi-Fi

Wi-Fi is another name for IEEE 802.11b, and its biggest feature is that it is convenient for people to access the Internet anytime, anywhere. However, for smart home applications, the shortcomings (such as high power consumption, and strong networking expertise) are obvious. High power consumption is a fatal flaw for deploying low-power sensors anytime, anywhere, so although Wi-Fi is very popular, it only plays a supplementary role in smart home applications.

(3) Zigbee

The basis of Zigbee is IEEE802.15. But IEEE only deals with low-level MAC layer and physical layer protocols, so the Zigbee Alliance extends IEEE to standardize its network layer protocols and APIs. Zigbee is an emerging short-range, low-speed, low-power wireless networking technology that is primarily used for short-range wireless connections. It has the characteristics of low complexity, low power consumption, low rate, low cost, self-networking, high reliability, and ultra-visual distance. At present, the application of IoT and Zigbee technology in smart homes, industrial monitoring, and health care have great integration.

(4) Sub-GHz (315M/433M/868M/915M)

These radio frequency technologies are widely used in vehicle monitoring, remote control, telemetry, small wireless networks, identification, non-contact RF, and other places. Due to their weak anti-interference ability and general reliability, the application effect in smart homes is not very good.

In a word, wisdom changes life. Smart home brings convenience to life, so which one do you prefer, wired mode or wireless mode? Please share your ideas in the comment zone.
