Smart home millimeter radar human body presence module to achieve the whole scene intelligent, when we mention millimeter wave, many people will associate it with 5g, but we do not know that the application on 5g is just the embodiment of the nature of millimeter wave. Technically, we call electromagnetic waves with wavelengths of 1 to 10 millimeters millimeter, so it is essentially located in the same way as microwave and far-infrared waves. However, because its wavelength range overlaps with microwave and far-infrared waves, millimeter waves have the characteristics of both spectra, which also makes millimeter waves more common in applications.
Accurate information collection is the guarantee of intelligence
In practical applications, the demand for spectra is mainly used for monitoring, that is, millimeter radar body presence modules designed according to different requirements. Because millimeter wave has the characteristics of speed of light measurement, adapt to various temperature and humidity environment, wide monitoring distance, high tolerance of physical characteristics of the measured target, multi-information testing and so on, compared with the current widely used ultrasonic wave, infrared, laser, millimeter wave radar has a better effect in the field of smart home, but because of its technical specificity, Millimeter wave radar is mainly used in military and automobile fields, and the price is usually thousands or even tens of thousands of yuan. Consumer electronics grade millimeter wave radars did not appear until recent years, so they will be used more widely in the field of radar sensors.
The current sensor solutions, including acoustic wave, infrared, laser and other sensor technologies, have been widely used in public facilities, office buildings and home scenes, which have great limitations on the environment and physical characteristics of the measured target, especially in the interference of light source and temperature, easy to cause inaccurate measurement. For example, we often encounter voice-controlled lights off, or home infrared sensors misdetect moving objects and so on, know that sensors as intelligent products "eyes", information is not accurate, no matter how intelligent products will become "intelligent barriers", this is also the problem of many intelligent products, for artificial intelligence, accurate information collection is the basic guarantee.
For millimeter radar human presence module, due to its own information transmission characteristics, the data can be measured including speed, direction of movement, distance, Angle and other information, with excellent anti-interference ability. By detecting the change of microwave signal, the existence state, position and motion trajectory of human body in space are determined accurately. Even the relatively still human body can accurately perceive it, regardless of environmental conditions such as temperature, dust, and light source.
Take the recently released millimeter-wave AI sensor for example. In addition to focusing on our displacement movements, the millimeter Radar human presence module includes breathing, heart rate, temperature and other data. For example, when we turn off the light at night, the millimeter-wave radar can judge whether to turn over or get up according to the changes in speed, Angle and position, and then use the data model for the artificial intelligence system to judge whether to turn on the night light or the room light next, greatly improving the accuracy and making the user experience more intelligent.
Another example is how to go home at night without affecting the family sleeping at home. When opening the door at home, you can actively adjust the brightness of the light source, or open a certain range of lights, so as to reduce the impact on another person while ensuring the light source; When the air conditioner is used in summer, the sensor controls the direction of the air conditioner by sensing the position of the human body, avoiding direct blowing; Judge the toilet behavior, turn on the exhaust or air warming, etc. These are all information collected and transmitted through millimeter waves, and then linked the effects of different household products through artificial intelligence judgment, so that people can experience a truly smart home while being more green, environmentally friendly, low-carbon and energy-saving.
According to the data provided, the millimeter radar human presence module can perceive the subtle movements of the human body within tens of square meters, with an accuracy of 99.9 percent. In this space, it can also be finely divided to 1 square meter. In addition, the positioning accuracy of human body position and trajectory tracking is controlled within ±0.5m. Through the fusion of infrared sensing ability, the moving object can be double judged, effectively judge whether the moving is human body, eliminate interference, and make accurate operation.
The application of millimeter wave radar is not only that
In addition to the above scenario application, millimeter radar human presence module can also achieve more achievements in other aspects. Including personal and property security monitoring, elderly care, health and safety can have better performance, including intelligent door locks, smart wearable devices, and even enterprise applications, public facilities, can meet the needs of different scenarios. The main reason is that compared with the previous infrared equipment, relying on glass, plastic and other transparent materials as the shell, ultrasonic equipment needs to avoid the shortcomings of the sensor, millimeter wave radar is less limited, does not need to have a specific appearance setting like the infrared sensor, and does not need to be installed in a wide range of viewing angles like the smart camera, Penetrability features can be integrated into different Settings as a basic hardware feature, and some health monitoring products can even be designed to be contactless, which also allows for more variety in product design and development.
As a part of the intelligent ecology, MM radar human presence module behind the support of more than hundreds of brands, including traditional large electricity, kitchen small electricity, household appliances, personal care beauty cosmetics, furniture, lighting shading, electric HVAC, safety induction, balcony bathroom, audio-visual entertainment, education, office, tourism, health care, sports equipment, robot toys and other categories, It can also provide sensor iteration for these brand products to realize more functions that have never been realized before. The open ecology gives partners more research and development direction, but also gives users more customized and personalized customization choices, and cooperate with upstream and downstream to promote the development of intelligent life.
Millimeter wave radar technology is a leapfrog supplement to smart home devices and usage patterns. Help people build smart home systems more comprehensively. At the same time, the commercialization of millimeter radar human presence module technology is more important for areas other than smart homes. Through technology iteration, it can influence people's working and living habits and realize the intelligence of the whole society and different fields.
