1. Introduction of Smart Home Advantages
1. The necessity of home intelligence
With the development and changes of social economic structure, family population structure and information technology, people have put forward higher requirements for the safety, comfort, efficiency and transparency of the home environment. At the same time, more and more households require home products not only to have simple intelligence, but also to require the entire system to be simple, convenient, easy and safe in terms of function expansion, extension and service. Obviously, our home life needs to change.
2. The difference between IoT smart home and traditional smart home
In the traditional sense, it is generally believed that smart homes bring about an improvement in the quality of life. In fact, IoT-type smart homes are changing these views. The most significant change is practicality, convenience, and ease of integration. There are all kinds of electrical appliances in every home, whether it is a so-called smart refrigerator, air conditioner or traditional electric light, TV has always been working independently due to different standards, from the system point of view, they are all fragmented, Chaos and disorder are not an organic, organized whole. As the family owner, the time cost, management cost and control cost of these messy electrical appliances are usually very high and unnecessary.

The emergence of wireless Internet of Things technology has brought new industrial opportunities to traditional smart appliances and smart homes. Through it, various electrical appliances in the home can be easily and organically organized through wireless to form a complete system, so that Achieve seamless perception and complete management. This previously unimaginable and deeply challenging application today becomes easy, convenient and very interesting once connected using wireless IoT technology. These applications are not just about improving the quality of life, they can be seen to a greater extent as the most basic needs of a modern family.
Compared with IoT smart homes, traditional smart homes are not easy to expand, have low flexibility, poor compatibility, expensive upgrade costs, and high maintenance costs.
3. Comparative analysis of various wireless smart homes
Introduction and comparison of common smart home technologies
Although the concept of smart home has been around for a long time and the market demand has always existed, the development of smart home has not been widely applied due to the breakthrough of related technologies for a long time. The smart home technologies currently in the market are introduced as follows:
Wired
In this way, all the control signals must be connected by wire, and the signal lines on the controller side are scary, but it is also very difficult to troubleshoot problems. The shortcomings of the wired method are very prominent, complicated wiring, heavy workload, high cost, difficult maintenance, difficult networking, and poor scalability. These shortcomings ultimately lead to the wired smart home only staying in the small-scale pilot stage, and cannot be rapidly promoted on a large scale.
Wireless
The wireless system used in the smart home needs to meet several characteristics: low power consumption, stability, and easy expansion of the network; as for the transmission speed, it is obviously not the focus of such applications.
There are currently several wireless methods available for smart homes:
Bluetooth: It is a radio technology that supports short-range communication of devices (generally within 10m). It can exchange wireless information between many devices including mobile phones, PDAs, notebook computers, and related peripherals. However, the communication distance of this technology is too short, and it is also a point-to-point communication method, which is not applicable to the requirements of smart home.
It should also be noted that Bluetooth has recently launched the 4.0 standard. This new standard uses a low-power design and the communication distance also reaches the 2.4G wireless signal range, but its shortcomings are still obvious, security, networking capabilities and anti-interference ability Not enough, there is no network self-healing function. The leaks of Bluetooth are very common. The networking scale of the new standard generally cannot exceed 300, and Bluetooth is easily interfered.
WiFi: In fact, it is another name for IEEE802.11b. It is an industry term issued by an organization called "Wireless Ethernet Compatibility Alliance" (WECA), which translates into "wireless compatibility certification" in Chinese. It is a short-range wireless transmission technology that can support radio signals for Internet access within hundreds of meters. Its biggest feature is that it is convenient for people to access the Internet anytime and anywhere. But for smart home applications, the shortcomings are obvious, high power consumption, poor networking capabilities, and low security. So although wifi is very popular, it only plays a supplementary role in the application of smart home.
315M / 433M: These wireless radio frequency technologies are widely used in vehicle monitoring, remote control, telemetry, small wireless networks, industrial data collection systems, wireless tags, identification, non-contact RF, etc. Some manufacturers have introduced them into smart home systems, but due to It has weak anti-interference ability, inconvenient networking, general reliability, chaotic standards, and low security. The application effect in smart homes is unsatisfactory and universal, and it is eventually abandoned by mainstream manufacturers.
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 expanded IEEE to standardize its network layer protocols and APIs. ZigBee is an emerging short-range, low-rate, low-power wireless network technology, mainly used for short-range wireless connections. It has the characteristics of low complexity, low power consumption, low speed, low cost, ad hoc network, high reliability and high security. It is mainly suitable for application in fields such as automatic control and remote control, and can be embedded in various devices. In short, ZigBee is a cheap, low-power, self-organizing short-range wireless communication technology.
Second, the comparative advantage of ZigBee smart home products and traditional smart home products
Understanding of smart home in the context of Internet of Things
An important feature of the Internet of Things is that it can be quickly deployed on a large scale and can be operated stably for a long time. This feature requires that our home products must have wireless, seamless, green, safe, and reliable capabilities. From these basic capabilities, the traditional The so-called smart home products obviously can no longer meet the requirements of the Internet of Things era.
ZigBee's initially anticipated application areas include consumer electronics, energy management, health care, home automation, building automation, and industrial automation. With the rise of the Internet of Things, ZigBee has gained new application opportunities. The most widely used network edge of the Internet of Things is the sensor or control unit. These are the most basic, core and widest unit cells that constitute the Internet of Things, and ZigBee can coordinate and communicate with each other among thousands of tiny sensor drive units. And these units only need very little energy, and relay the data from one network node to another through radio waves, so its communication efficiency is very high. This technology's low power consumption, anti-interference, high reliability, easy networking, easy expansion, easy to use, easy to maintain, and convenient for rapid large-scale deployment and other characteristics conform to the requirements and trends of the development of the Internet of Things. From a technical point of view, the application of the Internet of Things and ZigBee technology in smart homes, health care, industrial and agricultural monitoring, etc. are very fused. Compared with other wireless technologies, ZigBee is based on its investment, construction, maintenance, The advantages of standardization (international HA standard) and other aspects will surely be more widely used in the field of Internet of Things smart home.
The main advantages of ZigBee and common wireless technologies:
From the perspective of networking capabilities, it can be seen from Figure 1, Figure 2 and Figure 3 that wireless technologies such as Bluetooth, WiFi, 315M / 433M are only suitable for simple star networks, with limited networking capabilities and no network repair capabilities, while ZigBee The network can form a tree network other than the star network and a more complicated mesh network.
From the perspective of security, ZigBee has a unique security layer and uses 128K advanced encryption technology, which has very high security. However, the security of wireless technologies such as Bluetooth, WiFi, 315M / 433M is generally poor, and leaks are frequent.
From the perspective of reliability, ZigBee adopts both frequency hopping and spread spectrum technologies, which have strong anti-jamming capabilities, while Bluetooth, WiFi, 315M / 433M and other wireless technologies have general anti-jamming capabilities. It is easily intercepted by the air and easily simulated, and the reliability is very low.
