New breakthrough in Huami's self-developed road! Release Huangshan 2S chip, Zepp OS, blood pressure monitoring engine
On July 13, at Huami Technology's Next Beat conference, Huami Technology launched the wearable device chip Huangshan 2S chip, self-developed operating system-Zepp OS, PumpBeats blood pressure monitoring engine. In addition, Huami Technology CEO Huang Wang also revealed that Huami Technology is entering the field of MRI health monitoring.
Why make a chip? Huami believes that the task of health monitoring in wearable device products is becoming more and more important, and the energy consumption of bracelets and watches has also increased. However, there is no chip on the market that can achieve true long battery life. Therefore, Huami Technology is in Huangshan 1 On the basis of No. 2 and Huangshan No. 2, the Huangshan 2S chip was upgraded and iterated.
According to Zhao Yajun, the co-founder of Huami Technology, the Huangshan 2S chip has upgraded the CPU architecture and adopts a dual-core RISC-V architecture. Compared with Huangshan No. 2, the computing performance has increased by 18%, and the operating power and sleep power consumption have been reduced. 56%, 93%, to achieve the combination of supercomputing power and ultra-low power consumption.
In addition, Huangshan 2S has an independent 2.5D GPU, GPU graphics performance has increased by 67%; at the same time, it is equipped with a convolutional neural network acceleration processing unit, which can quickly identify the type of disease, and the recognition speed of atrial fibrillation is 26 times that of pure software calculation. Zhao Yajun mentioned that Huangshan 2S has been successfully taped out in March this year and is one of the core chips of the third-generation Amazfit smartwatch.
In 2019, Huami launched the "Huangshan No. 1" based on Huami's self-developed RISC-V architecture, which integrates cardiac biometrics, ECG, ECG Pro, and abnormal heart rhythm monitoring engine, which is used in AMAZFIT Mi Dong Health Watch and AMAZFIT SmartWatch 2 on. In 2020, Huami Technology launched Huangshan No. 2 with built-in local biological data to calculate the NPU. The recognition speed of atrial fibrillation has been increased by 7 times, and the power consumption has been reduced by 50%. Judging from the introduction at the press conference, the blessing of Huangshan 2S will refresh the performance record of Huami smartwatches in terms of function, performance, and power consumption.
According to an IDC report, Huami's smartwatch shipments in the first quarter of this year ranked among the world's TOP5, ranking fourth, an increase of 68.8% year-on-year. Cumulative shipments of bracelets and watches have reached 820 million units. At present, the positioning of Huami watches is mainly in the mid-end market. After being equipped with the superior performance of Huangshan 2S, Huami may be able to boost the impact of Huami into the high-end market and increase market share.
In addition to the performance improvement, Huami's self-developed operating system Zepp OS will bring a new interactive experience to Huami smartwatches. Huami co-founder Fan Meihui mentioned that there are currently two main operating systems, one is based on mobile phone operating system magic changes, and the other is a variety of ready-made embedded real-time operating systems, both of which are not suitable for portable smart wearables. product. The bottom layer of Zepp OS is based on the FreeRTOS microkernel open source code, which reduces operating power consumption by 65% and increases battery life by 190%. It is expected to be released in the fourth quarter of this year.
Zepp OS integrates 150 kinds of dials, which enriches the interactive experience and opens up the possibility of connecting to the cloud. For example, in the future, you can use a GoPro sports camera to take pictures. Cooperate with Yunzhisheng and other companies to deeply optimize offline voice technology; in the health monitoring function, after 5 years of technical research, Huami Technology has launched the blood pressure monitoring engine PumpBeat, which can achieve 30s detection, and will continue to promote 24-hour blood pressure monitoring in the future. Through the verification of Peking University First Hospital, clinical trials have shown that the average absolute deviation of the blood pressure monitoring engine is lower than 5.14mmHg for systolic blood pressure and 4.88mmHg for diastolic blood pressure.
In addition to basic monitoring functions, Zepp OS has created an open health management platform that supports access to functions such as blood pressure and blood sugar to achieve 72-hour health monitoring. In addition, it integrates the TCP/IP network protocol stack and can initiate a network call to the cloud for help in an emergency.
In the field of wearable devices, there are currently Apple’s Watch OS and Hongxing systems. Why does Huami make its own OS? Huang Wang once publicly stated that it is not enough to use smart wearables as a supporting device for mobile phones. Wearables have an independent core value that is more important than collaborative supporting value-health. Judging from today's press conference, Huami is deriving horizontally and vertically in the field of wearable devices, not only focusing on smart wearable devices such as watches and bracelets but also investing in and promoting global portable MRI technology research and development.
Huang Wang revealed that Huami is building portable MRI equipment, investing in two foreign MRI companies, Hyperfine and Promaxo, and investing in an independent team in China. To break the MRI "difficult to find one machine" situation, MRI can be done in general outpatient clinics and urban areas. According to reports, the device also embeds artificial intelligence algorithms, deep learning, and other technologies, which can quickly produce images, solve the problem of artifacts, and improve imaging quality.
Huami Technology's determination to deploy chips, smart wearable terminals, and health cloud services through its "chip-end cloud" strategy is evident. Huang Wang emphasized that Huami Technology has invested an average of 410 million yuan in research and development expenses each year in the past three years, of which 538 million yuan will be invested in 2020; it is equivalent to two to three times that of some emerging Internet companies and IoT smart hardware companies.
But how to achieve a balance between input and output is another problem that Huami has to face. From the financial report of the first quarter of this year, Huami Technology achieved revenue of 1.147 billion yuan, a year-on-year increase of 5.4%, but it belongs to the company. The adjusted net loss reached 29.05 million yuan. Huami, which is "going to millet", has a long way to go in the future. This conference is just another new starting point for Huami in the field of smart wear.
