The communication protocols mainly involved in smart home technology
The current smart home technology mainly refers to communication or control protocols. Professionally, it mainly involves two parts: hardware interface and software protocol. In general, the market is mainly divided into wireless communication, wired communication and power carrier.
Wired mode
RS485
IEEE802.3 (Ethernet)
EIB/KNX
LonWorks
X-10, PLC-BUS
PLC-BUS overview
CresNet, AXLink, etc.
In addition to X-10, PLC-BUS, there is almost no communication technology specifically developed for the smart home industry. What is interesting is that the X-10 power line carrier technology was successfully developed as early as the 1970s. In the field of application and home automation, it was introduced and promoted in China around 2000, but 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, it is also the various technologies. problem.
Why has power line carrier technology ever been able to be expected by many people? The main reason is that this technology can avoid additional wiring when deploying smart home systems. Separate wiring is a difficult task that is complicated to implement, difficult to maintain, and cost-free, so we don't want to be alone for this. The demand for icing on the cake is spending so much in the house. If there is a perfect technical solution that can save the power line at home, it will be widely used in the future. The problem of power line carrier technology itself is mainly due to stability, because the power network environment is too bad, especially for the domestic power grid. If it is to achieve stable and stable communication on the power line, it will cost too much, although later PLC-BUS has improved certain stability, but 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 the 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.
Wireless mode
RF technology
Bluetooth
WiFi
ZigBee
Z-Wave
Enocean
The emergence of wireless technology has satisfied people's yearning for freedom, but is the PK of wireless technology and wired technology over? Before the emergence of a killer wireless technology, the smoke will continue. In addition to the power line carrier, all wired technologies will say how stable and necessary the system is based on dedicated communication cables. But people will not be satisfied. From the most common point-to-point technology such as RF433/315MHz, they try to find a stable and cheap wireless smart home technology solution. The original smart home system pays the most attention to stability, flexibility and security. It seems that Zigbee came into being, and Bluetooth is also actively moving closer to the smart home industry; WiFi is also popular as a low-cost, easy-to-internet smart home technology solution.
