Millimeter wave radar is ready to go

Dec 31,2021

In the era of smart life, smart home products have entered numerous households. Such conversation occurs every day.

However, sometimes the intelligent devices are "mentally retarded", making people speechless.

For example, traditional human body sensors often misreport, and cannot "focus on people" to truly perceive the existence of people in the house. They often turn on various devices back and forth, making a chaotic scene. For another example, many devices are equipped with cameras. Although they promise to protect privacy, can they ensure data privacy in the true sense?

How to make home perception more accurate, efficient, convenient and secure?

Recently, Li Tang, Product Director of Wanjiaan Research Institute, delivered several speeches on technical topics about millimeter-wave radar at the summit forum "Focus on Internet of Things Technologies and Get Insights into Cutting-edge Applications" and the Shenzhen Smart Home Innovative Application Summit Forum, and shared his views on how to use millimeter-wave radar technology to overcome the difficulties of home Internet of things in terms of accurate perception, security and privacy protection.

As a sensing and detection technology with higher precision, millimeter-wave radar enjoys significant advantages of ultra precision and high cost performance compared with camera, LiDAR, PIR, ultrasonic and other technologies.

First of all, millimeter-wave radar technology can increase the accuracy of detection range to 10m, and can accurately identify movements with amplitude of 1mm, ranging from violent exercise to static breathing, and can connect home appliances to give out security alarm. Secondly, millimeter-wave radar technology can penetrate clothing, wood, plastic, glass and other materials, without being affected by the external environment such as rain, snow and dust, and can ensure 24/7 perception. It is worth mentioning that millimeter-wave radar technology can provide non-contact perception of life, not only getting rid of the problem that traditional sensing devices have to be worn day and night, but also protecting users' security and privacy. 

Generally speaking, the millimeter-wave radar, which is featured by long sight distance, accurate perception, 24/7 perception, anti-harsh environment and non-infringement of privacy, can provide new development ideas and directions for the rapid development of smart home Internet of things.

As a global professional AI internet of things solution service provider, with AIoT cloud platform as the core, Wanjiaan focuses on the in-depth research on "video sensing & radar sensing" technologies. With many years of practical experience in project implementation, Wanjiaan has developed human perception radar, fall alarm radar, vital sign monitoring radar, gesture control radar and other modules and related solutions, providing more possibilities and attempts for the development of smart home Internet of things.


The human perception radar can accurately perceive each breathing

The human perception radar can capture millimeter-level motion, and realize static human perception and motion trajectory tracking by detecting human signs, states and other slight movements. Based on the analysis of perceived data and user behavior tracking, we can predict the number of people in a hotel, homestay or residential house, and make use of linked control of electric lights, air conditioners, air purifiers, water, gas valves and other appliances to reduce carbon emissions without lowering life standard. This is also conducive to helping China implement the “30·60” decarbonization strategy, and restoring green mountains and green waters to win the "Blue Sky Defending War".


Vital Sign Monitoring Radar - A Cool Technology to Detect Vital Signs Detection

The vital sign monitoring radar can accurately identify the respiratory and heart rate data without contact, judge the user's sleep quality through in-depth analysis of respiratory depth, heart rate, body dynamic parameters and other data, and provide auxiliary data support to identify potential respiratory diseases in sleep breathing. The sign monitoring radar can be widely used for the construction of smart home, smart elderly care, smart hospital and rehabilitation center projects. With 24-hour real-time monitoring and care, it can meet the requirements of elderly care monitoring in house, community and institution, and alleviate the elderly care problems in the upcoming aging society.


Fall Alarm Radar Can Provides 24/7 Attentive Care for the Elderly People

According to the data of China's disease surveillance system, falls have become the primary cause of injury and death among adults aged ≥65 years. In order to promote the establishment of a perfect elderly care system, we must actively take preventive and emergency measures to deal with falls. For private places such as bathrooms, toilets and bedrooms, the fall alarm radar can recognize human postures and movements through multidimensional cloud data, so as to judge whether the person is standing, sitting or falling. In case of abnormal behaviors such as falling, it will give a real-time alarm to notify the guardian to give treatment immediately.


Gesture Control Radar Enables You to Control Remote Things at Your Fingertips

The gesture control radar can complete millimeter-level motion capture and realize intelligent linkage through non-contact gesture interaction. Diversified algorithms provide gesture control in various forms, making interaction more natural and intelligent. The gesture control radar can be used for somatosensory games, smart home and automotive control. In addition, it can also help the disabled or the elderly people to complete their daily operations and live with more dignity.

According to the estimation of Zhiyan Consulting, the scale of Chinese smart home industry will maintain a growth rate of over 50% in the next few years, and the scale of home radar is expected to reach RMB 10.5 billion by 2024. The millimeter-wave radar technology will be widely applied in smart home, hotel, elderly care, education, office, hospital, transportation, smart driving, shopping mall and other fields, injecting vigor into traditional products and applications. Opportunities always coexist with challenges. Starting from the scenario-based applications, Wanjiaan takes the AIoT cloud platform as the enabling engine, mainly focuses on the three fields of smart home, office and vehicles, and leverages radar sensing technologies to fully integrate the industrial service ecology, provide full-stack solutions, and promote urban construction.
