The millimeter wave radar sensor of smart household appliances has the induction recognition of human micromovement. With the rapid rise of smart home, new technologies are also integrated into the products to improve the user experience. Millimeter wave radar has become a new generation of smart home sensors with high sensitivity and wide coverage. In recent years, through cooperation with domestic first-line home appliance manufacturers, including Haier, it has become an important supplier of millimeter wave radar sensors for domestic smart home appliances. Its technology, products, delivery capability and quality control have been fully recognized by the smart home appliance market.
However, as a new sensor, millimeter wave radar lacks relevant application standards in the field of smart home. This brings certain difficulties for the terminal manufacturer to select products (such as the frequency band requirements of electromagnetic wave, attenuation of electromagnetic signal by structural components, etc.). In addition, as a new product in the field of smart home, millimeter wave radar itself has a certain technical threshold (detection distance, Angle measurement and acceptance, etc.), which has become a barrier to further wide application of this product.
In order to promote the further application of millimeter wave radar sensor technology for smart household appliances in the smart home market, through the analysis of market demand, scene internal environment, consumer demand, and so on, constantly explore product use scenarios, actively open the upstream and downstream industry chain, and jointly standardize the millimeter wave radar technology standards. By accurately grasping the form of the industry, establishing and improving industry standards, leading the standardization of production and research and development of the industry, reducing the difficulty of product promotion, and promoting the further development of millimeter wave radar as a sensor in the smart home appliance industry.
As the human movement of the whole house, millimeter-wave radar can accurately determine the existence state, position and movement trajectory of human body in space by detecting the electromagnetic wave signal changes brought by human micromovement. It can also realize human presence sensing based on the detection of human vital signs. The millimeter wave radar sensor of intelligent household appliances has higher sensing accuracy and more comprehensive sensing ability. Induction control signals can be output directly by integrating a high-performance MCU. It can also develop richer algorithms with strong scalability, suitable for high-performance scenarios. It can be connected to other masters or sensors, and can also be used as a master sensor.
Like some friends will have the habit of getting up at night, drinking too much water toilet before going to bed, having nightmares getting up to drink water stress surprise, at night to see if the child kicks the quilt and so on. The intelligent millimeter wave radar sensor can judge the sitting and standing behavior of human body intelligently, trigger the night mode, and prevent collisions and other accidents.
In addition, the multi-person tracking scenario also attracts much attention, which can effectively solve the problem of direct air conditioning. Even if the previous air conditioning Angle is adjusted, the position needs to be repeated after the change. The embedded millimeter wave radar sensor can judge the trajectory of the human body and choose to follow and avoid according to the user's preference. No need to use the remote control repeatedly, can more intelligently adjust the air conditioning Angle.
Millimeter-wave radar sensors can also accurately identify subtle human movements and sense the presence of people in an indoor space. Currently, a series of body sensing scenario products have been created (body sensing, fall detection, multi-person tracking, hotel head counting, respiratory monitoring). The embedding of millimeter wave radar induction can solve many pain points of original perception in smart home, and effectively avoid the embarrassment of inaccurate micro-motion and lights off when there are people in the room. We have defined the comprehensive development of millimeter-wave radar. While standardizing technical indicators and developing standard products, we have lowered the original technical threshold, completed the professional measurement of radar technical indicators (frequency band, power consumption, attenuation, etc.), and the acceptance of product performance (measuring distance, Angle, etc.).
With product innovation and the cooperation of Haier Group on the industry standard of millimeter wave radar, it will further deepen the product development in the field of smart home appliances millimeter wave radar sensor home appliances, and promote the ecological cooperation and development of smart home appliances sensors.
