In the last part, I mentioned 12 smart home technologies. After I had a preliminary impression of these technologies, I found that these so-called Internet of Things technologies mainly solve the communication problems between home electronic devices and between us and humans. Let this communication become more accurate, stable, efficient and even intimate. We have seen a lot of intimate and ultimate smart home applications in many science fiction films. Many people have begun to call the intimate concept "wisdom". Of course, this mainly refers to the communication between humans and machines, which is called "human-machine interface" or "human-computer interaction" in the profession. Siri voice control has let us see the future development trend of human-computer interaction, that is, the communication between us and the machine will become more and more simple, it will be easier than to communicate with others, and even the machine will actively explore you. The demand for it, in order to meet your physiological and psychological needs, of course, here we are referring to healthy and reasonable needs.
Back to the topic, so in fact, the so-called "technology" discussed in the previous article still mainly stays in the communication between electronic devices, that is, Internet of Things technology, in smart home applications, which technology will be more applicable, let us try to professional The angle and the endless demand angle of human beings are taken separately. Of course, in the end, it is cheap and easy to use. That is, the high price-to-price ratio has always been the most mainstream demand of people:
First, the technical parameters are compared:
1. Wired technology (see the table on the special page for details)
2, wireless technology (see the table on the special page)
Second, functional application comparison
Wired technology
As can be seen from the above comparison table, except for X-10, PLC-BUS, there is almost no communication technology specifically developed for the smart home industry; and interestingly, the X-10 power line carrier technology was developed as early as the 1970s. Successfully started the application and home automation field. It was introduced and started to be promoted in China around 2000. However, the market situation has been difficult to open. The main reason why it is difficult to widely promote is that in addition to the equipment cost and people's needs are not matched, it is also The problems of the technology itself.
Why is power line carrier technology even able to be highly anticipated by many people? The main reason is that this technology allows us to avoid additional wiring when deploying smart home systems. The separate wiring is complicated to implement, difficult to maintain, and the cost is only It doesn't matter if it doesn't drop down, so of course we don't want to put so many lines in the house for this "icing on the cake" demand. If we have a perfect technical solution to save the power line at home, I I think it will be widely adopted in the future. Back to the problem of power line carrier technology itself, the most important thing is stability, because the power network environment is too bad, especially the domestic power grid. If we want to achieve stable and stable communication on the power line, it will cost too much. Although PLC-BUS has improved certain stability, it is still difficult to achieve stable and continuous communication quality. Moreover, the power grid environment is highly variable, and the later maintenance is a bit stretched and can be fixed for a while. In addition, power line communication involves secondary pollution to the public power grid and information security issues.
Therefore, although power line carrier technology has been produced very early, people are still looking for suitable wired technologies to develop smart home products from other fields, and even create proprietary technology agreements for product development. Of course, because various wired technologies have their advantages. Disadvantages, so it has always been a battle for the world, and perhaps because of this, the smart home industry has been ignorant, no breakthrough progress, the industry has also been small.
