That is, information equipment resources enjoy collaborative services, which is the industry standard of independent intellectual property rights in China. On July 17, 2003, with the approval of the Science and Technology Department of the Ministry of Information Industry, the standard working group of "Information Equipment Resources Enjoy Collaborative Services" was formally established, which was initiated by Lenovo, TCL, Konka, Hisense and Great Wall, and seven units participated in it (referred to as the standard working group of Blink, also known as "Blink") to jointly formulate Blink.
Function: Used for wireless connection between home appliances and digital products. However, at present, there are still relatively few commercial ones.
RFID:
Radio frequency identification (RFID) technology, also known as radio frequency identification, is a communication technology that can identify a specific target without establishing mechanical or optical contact between the identification system and the specific target, and read and write related data through radio signals.
Radio frequency, generally microwave, 1- 100GHz, is suitable for short-distance identification communication.
RFID readers are also divided into mobile and fixed. At present, RFID technology is widely used, such as library, access control system, food safety traceability and so on.
ZigBee:
ZigBee is a low-power LAN protocol based on IEEE802. 15.4 standard. According to international standards, ZigBee technology is a short-distance and low-power wireless communication technology. The name (also called the Purple Bee Protocol) comes from the eight-character dance of bees. Because bees communicate with their companions by flying and flapping their wings, that is to say, bees rely on this way to form communication networks in groups. It is characterized by short distance, low complexity, self-organization, low power consumption and low data rate. It is mainly applicable to the fields of automatic control and remote control, and can be embedded in various devices. In short, ZigBee is a cheap and low-power short-distance wireless networking communication technology. ZigBee is a wireless network protocol with low speed and short distance transmission. ZigBee protocol includes physical layer (PHY), media access control layer (MAC), transport layer (TL), network layer (NWK) and application layer (APL) from bottom to top. Physical layer and media access control layer conform to the provisions of IEEE 802. 15.4 standard.
Wireless network:
Is a wireless local area network, including 802. 1 1a/b/g/n and other standards. You can set up a Wi-Fi network by purchasing a wireless router.
Bluetooth:
Bluetooth (Bluetooth? ): is a wireless technical standard, which can realize short-distance data exchange between fixed equipment, mobile equipment and personal area network of buildings (using UHF radio waves in ISM band of 2.4-2.485 GHz). Bluetooth technology was first invented by telecom giant Ericsson in 1994 as a substitute for RS232 data line. Bluetooth can connect multiple devices, which overcomes the problem of data synchronization.
Today, Bluetooth is managed by the Bluetooth Special Interest Group (SIG). The Bluetooth Technology Alliance has more than 25,000 member companies in the world, which are distributed in many fields such as telecommunications, computers, networks and consumer electronics. IEEE lists Bluetooth technology as IEEE 802. 15. 1, but this standard is no longer maintained. Bluetooth Technology Alliance is responsible for supervising the development of Bluetooth profile, managing certification projects and maintaining trademark rights. The manufacturer's equipment must meet the standards of Bluetooth Technology Alliance before it can enter the market in the name of "Bluetooth equipment". Bluetooth technology has a set of patented networks that can be distributed to devices that meet the standards.
