Smart home appliances are household appliances formed by introducing microprocessors, sensor technologies, and network communication technologies into home appliances. They automatically sense the status of residential space and the status of home appliances and home appliances. They can automatically control and receive residential users in homes or remotely. The control instructions; At the same time, smart home appliances as an integral part of the smart home, can be connected with other home appliances and homes in the house to form a system to achieve smart home function. The difference between a smart home appliance and a traditional home appliance cannot be simply distinguished by whether or not an operating system is installed and whether a chip is installed. Their difference is mainly reflected in the "smart" word. With the continuous development of science and technology, the home appliance industry has also entered the field of intelligence. Regardless of whether white enterprises or small household appliances companies, kitchen power companies or black and white enterprises, the most talked about is intelligent products and strategies. Many companies have introduced smart new products and have also used the most advanced technologies. According to data from the Industry Research Institute of Forward-looking Industry Research Institute of China's Intelligent Household Appliance Industry Market Research and Investment Forecast, the smart home appliances will occupy nearly 50% of the market in the next four years. At the same time, smart home appliances and smart kitchen appliances The product's market share will also reach 28% and 25% respectively. In recent years, the smart white power industry has also begun to develop rapidly, and intelligentization has become the main direction of the market for most home appliance companies. Source: Forward-looking Industry Research Institute Although a wide variety of smart products have appeared in the market, the real smart home appliances are not only smart appliances, but also smart hardware and smart APPs. The development trend of smart appliances indicates that true intelligence is not just changing the size of the form or developing one or two independent new functions. The intelligent industry positioning should be systematic, global, and ecological. In recent years, as the home appliance industry continues to deepen its intelligence, the market for smart home appliances is also growing. From the analysis of the smart home appliance market, thanks to the increasing number of smart home appliance hardware products in the market and increasing popularity in the consumer market, The smart home appliance market is also growing very rapidly. The intelligent upgrade of home appliances is the future development trend. In the future, smart home appliances that integrate network technologies and IT technologies, including smart controls, infrared sensors, global positioning systems, automatic RF identification, and automatic scanning, will become more and more sophisticated. More and more people appear in everyday life. Smart home appliances technology makes home appliances so high-tech. With the development of technology, people can now not only realize remote control of home appliances, but also can upgrade home appliances through software control. The rise of smart TV can be said to be an innovation in China's TV market and China's home appliance market, represented by smart TV, which has led to the development of China's overall smart home appliance industry. From urban to rural areas, from personal needs to family needs, China’s smart TV population continues to grow. According to statistics, the number of smart TVs in China reached 112 million in 2015, and the number of smart TVs in China reached 146 million in 2016. It is estimated that the number of smart TVs in China will exceed 200 million in 2018, basically covering most households in China, and family and individuals are completely mature in the use of smart TVs. From the perspective of television prices, smart TVs with price below RMB 3,000 and prices between RMB 3,000 and RMB 5,000 are the most widely distributed and are most favored by users. The smart TV market is also mainly concentrated in the low-end and mid-range markets. The development of smart home appliances has a direct connection with the constant expansion and innovation of information technology, and a new term “Internet of Things†has emerged. Although IoT appliances cannot cover all the features of smart home appliances, it is actually the most obvious and most mainstream development direction of smart home appliances. The help of national policies in this area is also particularly timely and forceful. Small appliances will become the focus of future intelligence. First of all, small home appliances have a single function, and their own degree of automation is relatively high. Therefore, product intelligence is relatively simple. Second, the price of small household appliances is cheaper, and even if they are smart, the price will not exceed the consumer's ability to accept, so marketing is easier. Furthermore, due to the low technical difficulty of products, Internet companies are easy to intervene, and they can quickly open up the market through product cost-based sales. Finally, consumers have high expectations for the intelligentization of small household appliances, and the intelligent exploration of small household appliances is about to be completed, so small household appliances will become the focus of future intelligentization.
Yuhai Company is engaged to research
and development of piezoelectric products
and related piezoelectric products, the related piezoelectric products includes the piezo sensors and transducer.
The ultrasonic transducer is a kind of transducer that converts the ultrasonic signal into electric signal, or vice versa. Ultrasound transmitter and receiver is a transducer that can transmit and receive ultrasound. Ultrasound sensor is a kind of sensor, in essence, it is also a transmitter and receiver. The working principle of this kind of equipment is similar to that of radar and sonar. Active ultrasonic sensors can emit and receive reflected waves, and determine the distance of the target by measuring the time interval between transmission and reception. Passive ultrasonic sensor is actually a microphone that can convert ultrasonic signal into electrical signal.
