Smart home devices have exploded over the past few years. What was once called “home automation” and is still called “the Internet of Things” has now become a friendlier category we call the smart home. We have nearly all the heating, lighting, cameras, sensors, and new devices appearing every week to move your home into a connected future.
Over the past few years, we’ve transformed from a disconnected system to a world with emerging hubs, large devices like the Amazon Echo and Google Home serving as hubs that connect all connected services together, and emerging hubs like Apple Platform HomeKit and Samsung SmartThings. So what role does ZigBee play in the brave new world of the smart home? Smart home, the whole idea behind the smart home is to keep everything connected to everything, keeping you informed while your devices stay informed. This could be your lighting talking to your security camera, or your smart coffee maker turning on when you wake up. IoT might be a rather useless term, but really, that’s what’s going on, everything is connected, which means information can be shared and your life can be controlled without having to access everything individually.
If viewed from a generalized building, smart home devices are mainly used in smart buildings. The intelligent building industry has great potential for development and is considered to be a very important industry in my country’s economic development, and its leading role in the industry should not be underestimated. According to statistics, the proportion of smart buildings in new buildings in the United States is 70%, and that in Japan is 60%. In 2015, the proportion of intelligent buildings in new buildings in my country was about 30%. my country’s intelligent buildings started in 1990, 6 years later than the United States and 4 years later than Japan. By comparing the development history of intelligent buildings in the United States and Japan, it is expected that the proportion of intelligent buildings in new buildings in my country will remain 3% per year in the future. By 2021, the proportion of smart buildings in new buildings in my country is expected to reach about 57%. From the narrow sense of smart home equipment application, it is mainly concentrated in the commercial housing market, in which the application ratio of villas and high-end apartments is at a high level. From the perspective of the area of houses completed each year, the market scale forecast of the smart home equipment industry for new commercial residential buildings in my country from 2016 to 2021 is shown in the following table.
For the current smart home market, Dalian World Peace Group has launched a ZigBee smart switch panel solution based on NXP JN5189. This solution has the functions of customizing action functions with APP, freely controlling other products, and indicator light feedback, and conforming to the ZigBee 3.0 specification. , Interoperability with other manufacturers’ products, low power consumption, long transmission distance, self-healing self-organized network, stable bottom layer, low cost, and short development cycle, it has the advantages of low power consumption and low cost in the market.
The peripheral circuit of NXP JN5189 is simple. It only needs a crystal oscillator and a small amount of capacitors to build the smallest system. The design of the internal balun single RF output port and the transmit power of up to 10 dB save the cost of RF circuit design and external PA.
Solution hardware design architecture:
Choice of main platform
The main platform of this ZigBee switch panel application scheme adopts NXP JN5189, which has the characteristics of high performance, low cost and easy development. The reason for using this platform is that
① Cortex M4 core, low power consumption and stable operation.
② The maximum transmission power is +10 dBm, and the transmission distance is long.
③ The radio frequency circuit and internal circuit are fully optimized, and the receiving power consumption is reduced by half compared with the previous generation.
④ The working voltage range is large, which prolongs the battery life.
⑤ Stable NXP ZigBee 3.0 protocol stack, complete application layer software Demo, shorten customer development cycle.
⑥ Use the free IDE MCUXpresso provided by NXP for software development, which is safe and efficient.
⑦ The chip price has an advantage over similar products.
