Machine interconnection wireless network system

Abstract

The invention discloses a interconnection wireless network system comprising a central server, a WiFi wireless interconnection control station, a far-end node and a WiFi terminal, wherein, the WiFi wireless interconnection control station is used for providing access connection of the WiFi terminal and distributing the network address of the WiFi terminal accessed in a WiFi LAN and route forwarding network data; the WiFi wireless interconnection control station is wirelessly communicated with the WiFi terminal via optical fiber and the far-end node and forms the WiFi LAN with the WiFi terminal by taking the WiFi wireless interconnection control station as the center; the WiFi terminal comprises a WiFi device server but is not limited to the WiFi device server, and the WiFi device server is connected with an industrial machine device via the standard industrial data interface. The invention adopts an optical fiber radio distribution system to realize low cost, long distance and large-range distribution of WiFi radio-frequency signal and can be applied to places such as factories, office buildings and the like with large range, various devices and complex control.

Description

Technical field [0001] The invention relates to the field of industrial automation, in particular to a wireless network system for machine interconnection. Background technique [0002] Machine interconnection is Machine-to-Machine, or M2M for short. The goal of M2M technology is to enable all kinds of machines and equipment to have networking and communication capabilities, so that all kinds of machines and between machines and operators can communicate with each other. [0003] At present, there are traditional wired interconnection methods and emerging wireless interconnection methods for realizing machine interconnection in the field of industrial automation. [0004] Among them, the wired interconnection mainly uses standard industrial buses and industrial wired Ethernet to realize short-distance interconnection between machines. Due to the limitations of wired wiring and the growing demand for long-distance interconnection between machines, wireless interconnection between ma...

Problems solved by technology

Due to bandwidth limitations, this method cannot achieve high-speed data transmission (such as real-time video transmission), and must pay a certain network fee to the mobile company

This method is more suitable for networked control of devices with few networked devices and widely distributed devices, such as hydrological monitoring, etc. It is not suitable for factories, office buildings and other places with many devices, centralized control, and complex control.

[0008] Personal area networks, such as ZigBee and BlueTooth, are short-distance, low-speed wireless networks, suitable for short-distance, power consumption-sensitive, low-data-rate and less-equipment networking, and not suitable for large areas such as factories, hospitals, and office buildings. wireless network
