The invention relates to the field of electronic equipment, in particular to an intelligent wearable equipment.

Background technique

"Wearable smart device" is a general term for the application of wearable technology to intelligently design daily wear and develop wearable devices, such as glasses, gloves, watches, clothing and shoes.

In a broad sense, wearable smart devices include full-featured, large-sized, complete or partial functions without relying on smartphones, such as smart watches or smart glasses, etc., and only focus on a certain type of application functions, which need to be integrated with other devices such as smartphones. Used together, such as various smart bracelets and smart jewelry for physical sign monitoring. With the advancement of technology and changes in user needs, the form and application hotspots of wearable smart devices are also constantly changing.

Wearable technology has always attracted much attention in the international computer academic and industrial circles, but due to the high cost and technical complexity, many related devices only stay in the conceptual field. With the development of the mobile Internet, technological progress, and the introduction of high-performance and low-power processing chips, some wearable devices have moved from conceptualization to commercialization, and new wearable devices are constantly coming out. Google, Apple, Microsoft, Sony, Olin Many technology companies such as Bass have also begun to explore in-depth in this new field.

Smart wristbands are an emerging technology field, which can track users' daily activities, sleep conditions and eating habits, etc., and can synchronize the data with iOS and Android devices to help users understand and improve their health status. Although smart bracelets have powerful functions, for some specific groups (for example: Buddhists or Muslims), there are no smart bracelets that provide professional functions for this specific group, and ordinary smart bracelets are not based on The wearer's physical condition can automatically play the corresponding audio function. Generally, the hardware of smart bracelets is relatively simple. A single processor has to process the data of multiple modules, and the work is unstable, and the data is generally transmitted through the USB connector, and some use Bluetooth for transmission, but Bluetooth transmission The speed of Bluetooth is relatively slow. If it is to be transmitted through wifi, the heat generated by the side device will increase. In addition, the cost of Bluetooth is relatively expensive and the size and price of the chip are difficult to reduce. The anti-interference ability is not strong, and information security cannot be guaranteed.
