From the concept of obscurity to the topic of street and street, the development of smart homes has finally reached the critical point of eruption after the dual promotion of the Internet of Things and smart cities. According to Gartner's latest forecast, as of 2022, the proportion of smart homes in ordinary households in developed countries will increase exponentially, and a historic change will occur as the cost of sensing and communication functions in consumer products continues to decrease. .
As the most basic component of smart home, electronic components will play an absolute "promoter" role in this revolution. According to a survey by Global Source, the total purchase value of electronic components in China's electronics manufacturers will reach US$34 million in 2014, an increase of 26% compared with last year. CMIC experts also expect that by 2015, the international market share of electronic components will reach 50%, the Chinese market can reach 70%, and smart home will become the next "trillion-level" market for electronic components. How to catch this "trillion-class" ride has become an issue for electronic distributors.
Diversified demand promotes multiple marketing models
Smart home, as the name suggests, is a residential platform, using facilities integrated with home life to build an efficient management system for residential facilities and family schedules, improving home safety, convenience, comfort, and artistry, and achieving environmental protection and energy conservation. Living Environment. It can be said that smart home is the inevitable result of the development of the Internet of Things, and electronic components are the most necessary nodes for the preparation of this "net". From integrated wiring technology, network communication technology, smart home-system design security technology to automatic control technology, audio and video technology, all electronic technologies and terminals associated with smart homes will constitute a huge information processing cluster, and in this cluster Perceptual transmission, data processing and other aspects will be widely applied to a large number of electronic components.
We might as well imagine the following scenario: Someone set the "Leave" button when going to work, the home lighting, air conditioning, floor heating and other functions are automatically turned off, the family enters the unmanned mode; when he is about to get off work, through the mobile APP After selecting the "go home" button, the function that has been turned off gradually recovered, and the home returned to the warm check-in mode. These details need to be preset in the RF chip, and then the information is centrally collected by the relay device. Not only do these data need to be stored locally, but they will also be uploaded to the Internet, and the user will be tracked and pushed through the e-commerce platform to customize the information they may need. In this process, the supplier of electronic components as a manufacturer of radio frequency chips should be the operator of the e-commerce platform. However, due to the current mainstream "outsourcing" business model, this electronic service system will eventually fall on selling these On the chip's electronic component trading website, such as the domestic Huaqiang electronic network or foreign RS Components.
One-stop platform accelerates design process
Although the smart home shows the posture of the spark, in the actual operation, the longer design cycle is still a barrier that hinders its final landing. How to improve the research and development efficiency of engineers and provide them with convenient and fast channels will be the rules that must be observed in the development of smart homes. In this process, electronic component distributors are the best guarantee of this rule with multiple categories, low cost and high efficiency.
How should we focus on a large number of electronic distributors? Taking advantage of its own advantages and building a unique and comprehensive product camp and service system will bring non-negligible competitiveness to electronic component distributors. For example, RS Components, Asia's largest distributor of electronic components, RS currently has more than 2,500 suppliers worldwide, and 500,000 online tradable products, from sensors to wireless modules, to fully protect engineers. For the "one-stop" shopping needs of smart home. At the same time, in order to strengthen the online experience of engineers, RS invested a lot of money to optimize the trading system. Customers can quickly and efficiently find the items they need by completing more dynamic multi-attribute search filters, more eye-catching product categories, and real-time counting of product matches to complete search results and filter the necessary products. In terms of services, RS is committed to creating a variety of free tools and resources for engineers. Projects such as DesignSpark.Com, DesignSpark PCB, ModelSource, 3D CAD model library and DesignSpark Mechanical are constantly being introduced to help engineers achieve intelligence in an easier way. Home creativity and shorten the time from design to landing.
Challenges and opportunities will always coexist. Behind the high installation cost of smart homes and the pressure of interconnected maturity, the demand for electronic components and the desire for e-commerce platforms have brought unprecedented opportunities for electronic component distributors, and the accumulation of products and special services. It will serve as a propeller to help the "trillion" trains alongside the smart home era.
