If you want to ask what is the first impression of radar? Many people will naturally think of the classic old movie "British Air Battle". When the German Stuka planes bombed indiscriminately on the British Isles, the British used radar technology to fight back bravely, leaving many Chinese people with the radar. first impression.

      Like many new technologies, radar was originally used for military detection. Radar technology used in Britain was used to detect German aircraft as early as World War I. With the end of the war, radar has gradually entered civilian application scenarios, and has gradually penetrated into the fields of weather forecasting, object detection, environmental detection and geological survey. Until today, radar has become a product that is close to the people, and the current popular autonomous driving The field shines brightly.

       Recently, Tesla took the initiative to abandon the millimeter-wave radar and use the camera to realize the pure visual autopilot solution, but for now, among the autopilot solutions adopted by many domestic autopilot manufacturers, the millimeter-wave radar is still one of the mainstream sensors.

       The safety and reliability of the pure vision solution has not been confirmed. Under the "millimeter wave radar + vision" solution, Tesla cannot guarantee the safety of automatic driving. The pure vision solution currently looks more worrying. In the entire autonomous driving market, domestic and foreign autonomous vehicle manufacturers still retain the solution of lidar + lidar + camera.

       As cars enter the intelligent "deep water area", the development of the millimeter-wave radar market will further accelerate. Moreover, the application scenarios of millimeter-wave radar in the field of Internet of Things have surfaced, and autonomous driving is only the tip of the iceberg. In the construction of smart cities and smart buildings, millimeter-wave radars have appropriate application scenarios in security monitoring, traffic statistics, parking space monitoring, and gate system management. In terms of smart medical care and smart old-age care, non-contact monitoring of living bodies through millimeter-wave radar is a good substitute for cameras and solves many privacy issues.

      Recently, the lidar + camera solution for autonomous driving has been targeted by two companies, and their solutions are used in smart homes and smart pensions.

       Last month, Yunfan Ruida and Tuya Smart formally signed a cooperation agreement at the Consumer Technology and Innovation Exhibition (CTIS). The cooperation between the two parties took the lead in solving the problems of product networking and cross-protocol communication. In order to enable millimeter-wave radar equipment to achieve cross-protocol communication and support multiple connection methods such as Wi-Fi and Zigbee, Tuya Smart provides Yunfan Ruida with networking, communication and other modules, which can be used in conjunction with its radar modules.

Pension business can also become a blue ocean

     Technology companies are eyeing pensions, is this reliable?

      Regarding this issue, Li Gang, CEO of Yunfan Ruida, gave his own statement, he said, "China's aging process is accelerating, and in the field of elderly care homes, it is necessary to sense whether there are people at home, fall monitoring, as well as apnea, breathing and heartbeat data. Physiological detection such as sleep quality and sleep quality. Millimeter wave radar has four characteristics of high precision, low cost, privacy protection and non-inductive contact." For millimeter waves, the market for elderly care homes is tantamount to a "blue ocean".

      The blue ocean means a lot of uncertainty. No company dares to easily point out the future market development.

      Not long ago, the seventh census attracted widespread attention. Compared with the declining birth rate, another data also attracted a lot of attention. The population aged 60 and over was 264.02 million, accounting for 18.70% (among which, The population aged 65 and over was 190.64 million, accounting for 13.50%). Compared with 2010, the proportion of the population aged 60 and above increased by 5.44%.

       According to statistics, there will be 250 million elderly people in my country in 2020, and 60 million elderly people will fall every year. The elderly over 65 years old have a 30% to 40% chance of falling every year due to muscle weakness and other reasons. Elderly people have a 50% higher chance of falling.

       Falls are the leading cause of injury and death among the elderly, according to the Chinese Center for Disease Control and Prevention. This data is not only in China, but also in many countries around the world. Obviously, this has become a global topic.

       According to statistics from the World Health Organization, about 30% of elderly people in the world fall every year, 15% of them have more than two falls, and more than 300,000 people die.

      There are about 25 million accidental falls of the elderly at home every year in my country. The highest incidence of falls is between 3 and 6 am, with 54% beside the bed (falling off the bed); followed by the bathroom and toilet, accounting for 28%, while other daily activities only account for 18% in total, and the elderly fall in the bedroom, bathroom, and bathroom. The most dangerous place to fall.

      Falls have become a potential health risk for older adults living alone.

       The above not only reflects the current situation of the industry, but also gave birth to a scene - the elderly fall alarm.

Can Yunfan + Tuya open up the millimeter-wave radar market?

       But for Yunfan Ruida, smart home is the best place for civilian use of millimeter-wave radar, because there are so many things that can be done in this scene. However, as for the smart home market, there are many players here.

      For this market, Yunfan Ruida adopts a different market strategic layout - technology is the first, the scene is the first, and the platform is the last. Taking advantage of this market strategy, Yunfan Ruida realized the preliminary layout. Facing the next step, Yunfan Ruida started to follow up with heavy positions and then sought a platform.

        The Internet of Things era is a "hard requirement" for the interconnection of sensing devices. The cooperation between the two parties eliminates the "island barriers" between physical devices, and data is no longer a "chimney". Facing Yunfan Ruida's interactive operation requirements, Tuya Smart has opened up its hardware ecosystem to support Yunfan Ruida and over 310,000 cross-category and cross-brand Powered by Tuya smart devices to achieve interconnection.

       In cooperation with Tuya Smart, Yunfan Ruida has launched a variety of smart devices and a variety of radar modules with various algorithms, realizing the deep integration of millimeter-wave radar with functions such as fall alarm, sleep monitoring, heart rate and heartbeat monitoring, and applied to home care. , smart hotels, smart communities and smart homes.

       Behind the graffiti ecology is a collective competition and qualifying competition for smart homes.

       To put it bluntly, the word ecology is understood from the side as an environmental state, and its biggest feature is openness, so co-creation, co-construction, symbiosis, and win-win are the main theme of ecological construction; for the current millimeter-wave radar has opened up a new smart home. The market is blue ocean, and ecological construction is at the right time.
