Smart home appliance PCBA

Smart Home PCBs in Sensors

      In the Internet of Things era, all things are interconnected, closely linking people's lives, enterprise production and other aspects, creating a new ecological environment. One of the more popular applications of sensors in life is the smart home PCB system. The smart home automation PCB system is composed of sensors, actuators, control hubs, communication networks, etc., and obtains various data of the indoor environment through various sensors. At present, the sensors used more in the home include temperature and humidity sensors, smoke sensors, formaldehyde transmitters, etc. The sensor supports the pulse control system of the entire smart home, which is equivalent to the "nerve terminal" of the entire system. It is of great significance to the transmission of information and the intelligence of command. In order to keep the indoor environment comfortable, environmentally friendly and safe, the sensor plays a role in the smart home automation PCB system. To the role of monitoring and data control hub, improve the automation degree of smart home automation PCB system monitoring. Improve the automation monitoring level of smart home PCB system.

      Smart home appliances are home appliance products formed by introducing microprocessor, sensor technology, and network communication technology into home appliances. At the same time, as an integral part of smart home, smart home appliances can be connected with other home appliances, homes and facilities in the house to form a system to realize smart home functions.

      First of all, the concept of intelligence is not a scientific term. People collectively refer to the ability to have some or all of the characteristics of intelligence as intelligence. Human intelligence is mainly manifested in the process of perception, thinking, judgment, learning, and execution.

      Smart home appliances can be called smart home appliances if they carry the characteristics of human intelligence on some home appliances, so as to partially or completely replace people to complete certain things, or complete things that humans cannot do. Therefore, products with sensitive perception, correct thinking ability, accurate judgment and effective execution ability, and comprehensive utilization of all these abilities are what we call smart home appliances.

      In fact, smart home appliances are not mysterious at all. Recalling the early electric irons and rice cooker thermostats, they actually have the characteristics of intelligence. But at that time, the characteristics of intelligence were relatively low, and the concept of intelligence was not formed. With the development of sensing technology, chip technology, RFID technology, and network technology, smart home appliances in the true sense have begun to enter our lives.

The difference between smart home appliances and traditional home appliances

      The difference between smart home appliances and traditional home appliances cannot be simply distinguished by whether an operating system or a chip is installed. Their differences are mainly reflected in the embodiment of the word "intelligence".

      First of all, the perception objects are different. Previous home appliances mainly sense time, temperature, etc.; while smart home appliances can sense human emotions, human actions, and human behavior habits, and can do some intelligent execution according to this perception. Secondly, the technical processing methods are different. Traditional home appliances are more mechanical, or it is called a very simple execution process. The operation process of smart home appliances often relies on the application and processing of modern technologies such as the Internet of Things, the Internet, and electronic chips. Finally, the needs to be dealt with are different. The corresponding needs of traditional home appliances are to meet some basic needs in life, while the consumer needs of smart home appliances are richer and higher.

     Therefore, the difference between smart home appliances and traditional home appliances is that smart home appliances realize anthropomorphic intelligence. The products capture and process information through sensors and control chips. In addition to automatically setting and controlling according to the residential space environment and user needs, users can customize according to their own habits. In addition, when a smart home appliance is connected to the Internet, it also has the attributes of a social network. In addition, smart home appliances can also be understood as Internet of Things home appliances.

     The rapid development of smart home appliances has become an inevitable trend, and the main reasons for its rapid development are as follows:

(1) The maturity and wide application of network technology and communication technology.

(2) The continuous improvement of the level of informatization has gradually reached the level of supporting the large-scale development of the smart home appliance industry.

(3) Internet infrastructure and technical conditions have made necessary preparations for the development of smart home appliances.

(4) Users' demand for high-level home appliances.

Features and functions

Compared with traditional household appliances, smart home appliances have the following characteristics:

1. Network function. All kinds of smart home appliances can be connected together through the home local area network, and can also be connected with the manufacturer's service site through the home gateway interface, and finally can be connected with the Internet to realize information sharing.

2. Intelligent. Smart home appliances can automatically respond to changes in the surrounding environment without human intervention. For example, smart air conditioners can automatically adjust their working status to achieve the best results according to different seasons, climates and user locations.

3. Openness and compatibility. Since the smart home appliances in the user's home may come from different manufacturers, the smart home appliance platform must be developed and compatible.

4. Energy saving. Smart home appliances can automatically adjust working time and working status according to the surrounding environment, so as to achieve energy saving.

5. Ease of use. Since the complex control operation process has been solved by the controller embedded in the smart home appliance, users only need to understand very simple operations. Smart home appliances do not just refer to a certain home appliance, but should be a technical system. With the continuous development of human application needs and smart home appliances, its content will be more abundant, and the functions of smart home appliances will also vary according to the actual application environment. There are differences, but generally should have the following basic functions:

(1) Communication function. Including telephone, network, remote control/alarm, etc.

(2) Intelligent control of consumer electronics products. For example, a microwave oven that can automatically control heating time and temperature, an intelligent air conditioner that can automatically adjust temperature and humidity, a TV/VCR that can automatically search for and record TV programs according to instructions, etc.

(3) Interactive intelligent control. The voice control function of smart home appliances can be realized through voice recognition technology; the active action response of smart home appliances can be realized through various active sensors (such as temperature, sound, motion, etc.). Users can also define different responses of different smart home appliances in different scenarios.

(4) Security control function. Including access control system, automatic fire alarm, gas leakage, electricity leakage, water leakage and so on.

(5) Health and medical functions. Including health equipment monitoring, remote diagnosis and treatment, elderly/patient abnormal monitoring, etc.

      The rapid development of intelligent control technology and information technology also provides the possibility for home appliance automation and intelligence. Smart home appliances are home appliances that have the functions of automatic monitoring of their own faults, automatic measurement, automatic control, automatic adjustment and communication with a remote control center.

      Traditional household appliances include air conditioners, refrigerators, vacuum cleaners, rice cookers, washing machines, etc. New household appliances include induction cookers, disinfection cupboards, steamers and stewers, etc. Regardless of new household appliances or traditional household appliances, the overall technology is constantly improving. The key to the progress of household appliances lies in the adoption of advanced control technology, so that household appliances have changed from a mechanical appliance to an intelligent device. Smart household appliances embody the latest technological features of household appliances.

Home Appliance Classification

        Smart home appliances are divided into two categories: one is to use advanced technology and equipment in electronics and machinery; the other is to simulate the experience of skilled operators in the home for fuzzy reasoning and fuzzy control. With the development of intelligent control technology, various intelligent home appliances are emerging, such as the combination of computer and numerical control technology to develop numerical control refrigerators, rice cookers with fuzzy logic thinking functions, frequency conversion air conditioners, fully automatic washing machines, etc.

        The degree of intelligence of smart household appliances is different, and the degree of intelligence of the same type of product is also very different. Generally, it can be divided into single intelligence and multiple intelligence. A single smart home appliance has only one function that simulates human intelligence. For example, in the fuzzy rice cooker, detecting the amount of food and performing corresponding control is a process of simulating human intelligence. In an electric rice cooker, it is impossible to use a weight sensor to detect the amount of rice, which is not allowed by the overheating environment. The detection of appetite can be realized by adopting the thinking process of a person who eats a lot and takes a long time to absorb heat, and adopts different control processes according to the difference of appetite. This kind of rice cooker is a kind of rice cooker with single intelligence. It uses fuzzy reasoning to detect the amount of food, and uses fuzzy control reasoning to control the whole process. A number of smart home appliances In a number of smart home appliances, there are many functions that simulate human intelligence. For example, the multifunctional fuzzy rice cooker has multiple functions of simulating human intelligence.              For example, LG Electronics released high-end smart home appliances equipped with revolutionary information services in South Korea. HomeChatTM is available on two popular mobile social apps, NLP and LINE, which have more than 300 million users. Through this technology, users can communicate and interact with LG's latest home appliances, and control, monitor and share their experience through mobile phones. HomeChatTM interprets what is truly smart for people. LG's high-end smart home appliance product line includes a refrigerator equipped with a camera, a washing machine that allows users to start or download laundry programs through HomeChatTM technology, and a NFC-enabled interconnection technology. Light wave frequency conversion microwave oven connected with WiFi.

       Common intelligent household appliances adopt cheap "fuzzy control" intelligent control technology. A few high-end home appliances use "neural network" technology (also called neural network fuzzy control technology). Fuzzy control technology is currently the most widely used intelligent control technology for smart home appliances. The reason is that this technology is consistent with human thinking, it is more convenient to understand and does not require advanced mathematical knowledge expression, and can be constructed with a single-chip microcomputer.

       However, fuzzy logic and its control technology also have a shortcoming, that is, there is no learning ability, which makes it difficult for fuzzy control home appliances to accumulate experience. The acquisition of knowledge and the accumulation of experience and the resulting new thinking are the most obvious manifestations of human intelligence. During the operation of household appliances, there are problems of external environment differences, internal parts loss and user habits, which requires household appliances to be able to learn these states. For example, the external environment of a washing machine is different in spring, summer, autumn and winter. Due to the difference in water temperature and ambient temperature, the washing procedures are also different. The washing machine should be able to automatically learn the washing procedures in different environments; in addition, In the early application of the washing machine, the parts of the washing machine were in a tightly coupled state. After the break-in period, the parts of the washing machine were in a forward coupling state. After long-term use, the parts of the washing machine were in a loosely coupled state. For different periods, the washing machine should make appropriate adjustments to its own state, and at the same time should generate a corresponding optimization control process; in addition, the washing machine should automatically learn the optimal condition under the condition of specific clothes quality and clothes quantity during many times of washing. Washing program, when the user puts in different amounts and different quality of clothes, the washing machine should automatically enter the optimal washing program after learning - this requires a new intelligent technology: neural network control.

       A smart refrigerator is a type of refrigerator that can intelligently control the refrigerator and intelligently manage food. For example, it can automatically switch the refrigerator mode to keep the food in the best storage state. Users can use their mobile phones or computers to know the type, quantity, freshness and quality of the food in the refrigerator anytime, anywhere, and can provide users with healthy recipes and nutritional taboos. Users can be reminded to replenish food regularly.

      The intelligent air-conditioning system can analyze and judge the temperature, humidity and air cleanliness installed in the house according to the external climate conditions and according to the preset indicators, and automatically turn on the functions of cooling, heating, dehumidification and air purification in time. At the same time, users can also remotely control the air conditioner through terminals such as mobile phones.

Current status and development

Status quo

       Jiang Feng, chairman of the China Household Electrical Appliances Association, believed in an interview with a reporter from China Business News that the capital market is a catalyst. The capital market is highly concerned about smart home appliances. Often with the concept of intelligence, the stock price will rise. Although smart home appliances are coming aggressively, the high price, lack of killer applications, and difficulties in interconnection have become obstacles to the "landing" of smart home appliances.

       First, there was the "billion gamble" by the head of Gree and Xiaomi, and then there was the "big words" thrown by Changhong Holdings Meiling Electric Appliances, saying that traditional functional refrigerators will disappear completely in the next 10 years, and the "smart machine era" of white goods will End the "feature machine era". Internet companies and traditional home appliance companies are competing with each other in the smart home appliance market to seize the "commanding heights" of the industry.

      Internet thinking such as user interaction, fan economy, and big data analysis is sweeping the home appliance industry. Some industry analysts predict that by 2020, the ecological output value of smart home appliances will soar from the previous 5 billion yuan to 1 trillion yuan, and the market size of smart terminals will increase to 800 billion yuan, and it is expected to achieve "20 times in 10 years". geometric growth. For smart home appliances to be "landed" and to achieve large-scale applications, firstly, whether the price is acceptable to the general public; secondly, whether the user experience is good enough to make consumers willing to pay for smart functions. However, traditional enterprises are burdened with huge historical burdens, and it is difficult to make major changes in their business models.

      Smart home appliances have unlimited imagination in terms of business model. Because user data is valuable, home appliance companies can create new value through data operations even if their hardware products make little or no profit. For example, share the information about what vegetables are missing in the customer's refrigerator and how often they buy them to the supermarket. However, when smart home appliances are still in the "information island", it can be said that "smart is easy to get, data is hard to find", and there is still a long way to the future.

      Especially after entering the "Mobile Internet Era", white goods appear to be "old-fashioned" in terms of networking and intelligent progress.

      Compared with color TVs, black home appliances that can already be connected to smart devices such as mobile phones, air conditioners, refrigerators, and washing machines are generally less intelligent. If consumers upgrade the whole set, the cost will naturally be high, and it is far from being as simple as changing a smartphone. It is undeniable that most of the home appliances in use are still considered semi-new products and are far from reaching their end of life. How many consumers are willing to "renew" and "pay" for them?

Develop

      Under the impact of the Internet tide, the concept of "smart home appliances" began to rise. According to the "China High-end Home Appliance Market Report" released by China State Grid, 40.7% of users have chosen the attribute of "intelligence", and it is expected that by 2015, this figure will rise to 60%.

      The three-network integration of telecommunication network, Internet, and TV network, and the "four-screen integration" of TV, mobile phone, PAD, and computer make space compression and time extension, and intelligence is an inevitable trend of the development of the times. After the integration of the three networks and the application of Internet of Things technology, all electrical appliances such as refrigerators, electric lights, air conditioners, TVs, DVDs, stereos, microwave ovens, and washing machines will enter the smart age. All home appliances can be conveniently controlled through mobile phones or other integrated devices, thus creating room for development in the interconnection and product upgrading of home appliances. Many home appliance manufacturers have released smart home appliance products one after another, which has accelerated the market pace of China's smart home appliance products, which will bring another reshuffle of the industry.

      For the product evolution of smart home appliances in the future, data analysis, the application of the Internet of Things in the home appliance industry has a good user base, and the user awareness is relatively high. Smart home appliances will be vigorously developed by manufacturers. It is believed that with the continuous development of my country's electronic information technology, the connotation of smart home appliances and smart houses will continue to change, and the market prospect of smart home appliances will be widely optimistic. Zhao Wenzhong predicted that in the future, the development of home appliances will be intelligent, realizing "man-machine dialogue, intelligent control, and automatic operation", which will have a huge impact on the daily life of existing families, and will also completely rewrite the status quo of the home appliance market and the industry structure. The interconnection of information equipment is an inevitable trend of intelligent home appliances in the future.

Prospect

      Since last year, the concept of smart home has been one after another, and the products have been surging. Both traditional home appliance companies and IT companies have taken the living room as the main battlefield for marketing. However, judging from the actual products, they are basically in the exploratory stage and lack disruptive innovative products. The starting point for many smart home appliances to launch products is based on the competition level, not the consumer level. Therefore, overall intelligence cannot be achieved in design.

       From the perspective of consumer demand for smart homes, no matter which brand or product it is, home appliances must be interconnected, controlled and interoperable, so that a real smart home can be formed. However, the current situation is that each brand's smart solution based on its own capabilities is really a trap. It only focuses on what it can do, and cannot meet the real needs of consumers. If consumers want to realize the dream of smart home, they can only choose the whole package of a certain brand. Therefore, either the purchase cost is too high, or the manufacturer does not have the strength to provide a full set of smart home products. Therefore, consumers need to use different brands of home appliances in their daily life, but they cannot be interconnected and controlled. In the end, each family is divided into multiple "islands" by different brands, thus losing the effect of intelligence.

       In reality, all brand manufacturers cannot be compatible with all competitors, but the embedded chip of Jialian International can achieve data compatibility without changing the original brand and function of the product. Regardless of Samsung or Apple, customers can be differentiated through third-party platforms. Under such a concept, it is not a competitive thinking, let alone short-sightedness, but integration, and an integrated platform is completed through integration.

       Driven by market demand, the iComhome home networking platform is just the beginning, but the trend is already obvious. As a home appliance and home furnishing enterprise, if it does not apply technologies such as big data and cloud computing, it will not be able to achieve "smartness", let alone realize it. smart family.

       Therefore, in the context of consumer demand dominating the market, smart home appliances and smart homes that do not enter the big data platform will eventually die out.

Outlook

       Looking forward to the future, today's smartphones have entered the lives of the public and become the ultimate control terminal, which is a prerequisite for the popularization of smart home appliances.

       Smart home appliances will become an indispensable part of smart homes. After perfect integration, they will have more efficient energy applications, interconnected home appliance networks, and cloud security.

       Home appliances with smart chips are controlled by the user's smartphone to complete the user's given instructions.
