Wireless local-area-network architecture technology in PLC communication

Abstract

The invention relates to a wireless communication technology and particularly relates to a wireless local-area-network architecture technology in PLC communication. A wireless local-area network is a significantly convenient data transmission system which uses a radio frequency technology and substitutes an old-fashioned local-area network which is comprised of twisted-pair copper wires so that the wireless local-area network is capable of using a simple access architecture to allow users to penetrate through so as to achieve an ideal state that one can travel everywhere with information around. A lot of disadvantages exist in the method of establishing communication between a small local PLC station and a central-control room. However, the wireless local-area-network architecture technology in the PLC communication is capable of displaying a lot of advantages. To use the wireless local-area network, construction is not so complex, particularly with respect to a newly built or rebuilt small control station and a radio antenna high in cost is not needed to buy either. Moreover, a complex programming problem is not needed to be taken into consideration and maintenance is significantly convenient. The proposed wireless local-area-network architecture method in the PLC communication is more practical compared with traditional methods.

Description

technical field [0001] The invention relates to a wireless communication technology, in particular to a wireless local area network architecture technology in PLC communication. Background technique [0002] Wireless local area network WLAN is the product of the combination of computer network and wireless communication technology, and it is a local area network that uses radio waves as the data transmission medium. Compared with wired LAN, wireless LAN is more flexible, mobile, easy to plan and adjust, easy to install, easy to locate faults, and easy to expand. Wireless LAN can be used not only as an extension of wired LAN, but also as a substitute for wired LAN. With the development of wireless communication, broadband network technology, and mobile Internet technology, wireless LAN as a broadband network solution will be more and more widely used. [0003] In today's industrial control industry, the bus or Ethernet connection has become the main connection method for PL...
