In recent years, Wearable Computer (WearComp) has quietly become a research hotspot, and the development momentum is very rapid. Wearable computer technology breaks the traditional interaction mode, makes people and computers into one, and improves people's overall interaction and computing power. It provides a ubiquitous way of computing and interacting all the time. The hardware of wearable computer systems has been greatly developed with the promotion of applications. Based on its characteristics, each component of the wearable computer (terminal device) is generally in a separate state, that is, "wear" in different parts of the human body. Traditional WearComp generally uses cables to connect each terminal device to various interfaces of the host, which limits the physical activities of the wearer and makes the port of the host more redundant. The introduction of wireless communication technologies represented by Bluetooth and GPRS technology in wearable computers can further develop the interaction of wearable computers towards mobility, accessibility, naturalness and simplicity. Compared with the traditional wired interface, the wireless design is more humane. Among them, Bluetooth technology solves the communication problem between each terminal device and the host in WearComp, and removes the restriction of many cables on people; GPRS technology allows WearComp to easily enjoy various wireless communication services provided by telecommunications service providers, and is always online. In addition, Bluetooth and USB bus The application of technology has simplified the overly complicated host interface of traditional wearable computers. On these foundations, a wireless communication technology has appeared in wearable computers. With the continuous development of ultra-miniaturization of computers and related components, wearable computers came into being, which is an inevitable product of people's pursuit of the concept of "people-oriented computer" and market demand. WearComp is a challenging and cutting-edge research field in computers. It is a new generation of computers after PCs, laptops and PDAs. It is also a cutting-edge technology product of computers. It expands the functions of the computer and opens up new application areas. It has a wide range of uses and huge market potential. As a new generation of computers (instead of new models), wearable computers will form a new industry and will profoundly change the competitive landscape of the computer market. Its social and economic benefits are incalculable. Wearable computers have special uses in many fields, and can be widely used in industries such as industry, military, intelligence, news, medical, business, agriculture, finance and securities, emergency rescue and disaster relief, and even daily life. Its combination with UC technology, intelligent housing, intelligent business, intelligent transportation, etc. will make a huge change in the future human life style and enter a highly digital and automated era. Industry is one of the most potential application fields at present, especially in some special occasions such as outdoor, outdoor, underwater, etc., wearable computers will play a very important role. For example: installation and maintenance of large and complex equipment, inspection and inspection, mining, field exploration, etc. The military is currently the other most potential application area for wearable computers, mainly used in reconnaissance, combat command, communication, operation and maintenance of complex weapon systems, and simulation exercises. According to different uses, the types of wearable computers are also diversified, and there are special wearable computers for scouts, artillery, armor, infantry, logistics personnel, and pilots. The main components of wearable computers include low-power embedded CPUs, a variety of portable peripherals and their interface devices, and power supplies with high energy and small volume; basic peripherals mainly include output devices and input devices. For the convenience of portability, the output device replaces the traditional desktop desktop display with a helmet display or glasses display, and the input device replaces the traditional keyboard with a voice-controlled or a keypad with fewer keys. In addition, according to different needs of users, corresponding external devices such as wireless communication devices, voice input and output devices, image acquisition devices, global positioning system (GPS), and various sensors are also required. However, in order to integrate many peripherals together, the corresponding interface circuit must be integrated on the motherboard. Therefore, interface circuit design technology is one of the key technologies in wearable technology. The wearable computer makes the human-machine relationship very close. At the same time, since various equipments are equipped on people, the location, shape, and convenience of operation must be closely combined with the natural attributes of people to form an integrated and harmonious human-machine interface. This poses new challenges for the research on the new generation of human-computer interaction. The rising of Bluetooth technology provides a good solution for realizing the maximum freedom of human-computer interaction. 30KW-200KW Brushless Generator Brushless Ac Generator,200Kw Brushless Generator,30Kw Brushless Generator,Brushless Power Generator 180Kw Jiangsu Lingyu Generator CO.,LTD , https://www.lygenset.com
