Wireless technology advantage highlights the main home

The smart home is based on a residential building. It integrates home-life related facilities using integrated wiring technology, network communication technology, security technology, automatic control technology, audio and video technology, and builds an efficient management system for residential facilities and family schedule affairs. Home safety, convenience, comfort, artistry, and environmental protection and energy-saving living environment. Wireless technology has a broad application prospect in smart homes. The unique technological advantages make wireless technology the mainstream of home security applications in the future.

First, the wireless smart home technology has obvious advantages The control signal of the wired smart home is stable, but the problem is also very prominent. In addition to complicated wiring, heavy workload, and maintenance difficulties, the high cost and difficulty in networking is not a small problem. For example, if the owner wants to add another smart device, he must reopen the wall and bury the line, which is really troublesome. These shortcomings eventually led to wired smart homes that only stayed in the concept and pilot phase and could not be widely promoted.

Obviously, such smart homes that connect control signals through wired methods do not have strong market prospects and development potential. In contrast, wireless smart homes gradually occupy the mainstream position in the market. The main reason is that this kind of smart home does not require complex and complicated network cabling, and can be installed in combination with the junior high school culture level; automatic networking, strong equipment expansion; low power consumption, low cost, in line with the concept of modern green life; timely maintenance services , can accurately detect the fault and repair it.

It is worth mentioning that at present, some wireless radio frequency intelligent products use 315M/433M technology, but due to its weak anti-interference ability, inconvenient networking, and general reliability, the application effect in smart homes is unsatisfactory. Discarded by mainstream vendors. Some manufacturers claim that the performance of wireless smart products is not stable because they are ulterior motives. Behind the scenes, they are driven by commercial interests and strategies for competition in the market.

Second, the wireless application of broad prospects Intelligent lighting: people come to light, people go lights off you may not think that in the standby switch is still off the plug, the standby power consumption of air conditioning is 3.47 watts, color TV 8.07 watts, PC host 35.07 Tiles, monitor 7.69 watts. Electrical appliances and luminaires are the two main sources of power for home use. Mr. Chen, a citizen of Hangzhou, since he had installed a smart home, when he was away from home to work in the morning, he gently shuffled his mobile phone to cut off the power of all electrical appliances and lights. When he came home from work, he was automatically turned on again, which was convenient for both the province and the province. Electricity.

In fact, with smart homes, there are many ways and means to achieve low-carbon energy savings and savings in electricity bills. For example, in order to achieve the effect that “people light up and people light off,” the lighting control system in smart homes can easily implement functions such as time switching and light/dark light adjustment, which can be used to perform illumination at different times and in different environments. Precise set up and reasonable management to achieve energy savings.

Compared with traditional lighting control methods, smart homes can save 20%-30% of electrical energy. Intelligent lighting technology allows the entire lighting system in the home to operate accurately in the most cost-effective manner, maximizing energy savings. In the winter and summer seasons, smart homes can also adjust the power of air conditioners and heaters at any time. This will ensure that the comfort of the human body will not be affected, but it will also save energy.

Smart Sockets: Real-time monitoring of daily electricity usage In addition, smart homes have other unique features in energy saving. For example, timed event management, in addition to the "people light, people go light off" sensor control function, automatic detection of brightness through the brightness sensor, automatic control of the central space and geothermal system through the temperature and humidity sensor, "scene control", a key switch function And so on, are all means to achieve energy saving lighting, smart power outlet energy saving, high-power electrical energy saving.

It is worth mentioning that the wireless smart socket not only can turn off the functions of all electrical power supplies at one time, but also can achieve the purpose of home power consumption and real-time monitoring because it increases the management of measurement information, power consumption information management, and electricity charges. Accounts, electricity monitoring and other new features.

For example, users can check their own power consumption at any time and anywhere, and can plan to use electricity, especially when the monthly electricity consumption may exceed the consumption budget, they can minimize the use of large-scale power-consuming equipment, such as water heaters, computers and so on. Due to the planned use of electricity and electricity savings, some households have a declining electricity rate, and now pay close to 40 yuan less per month.

Third, the wireless communication method into the future direction of smart home The choice of wireless and wired camps determines the future direction of smart home communications technology. At present, most domestic smart home companies have reached a consensus on the use of wireless communications in the future. The communication technology of the future smart home is certainly toward the direction of simple installation, convenient networking, and rapid debugging. Here we must mention that ZIGBEE technology has been widely used in the domestic Internet of Things industry, especially in the field of smart home applications. Early, and achieved good results.

Date, Bob Haley, chairman of the International ZIGBEE Alliance, stated that ZIGBEE is an emerging short-range, low-rate, low-power wireless network technology that is mainly used for short-range wireless connectivity. With low complexity, low power consumption, low speed, low cost, ad hoc network, high reliability, over sight. It is mainly suitable for applications such as automatic control and remote control, and can be embedded in various devices.
