Industrial looped network and 4G network automatic switching base station and work method thereof

Abstract

The invention discloses an industrial looped network and 4G network automatic switching base station and a work method thereof. The industrial looped network and 4G network automatic switching base station includes a wired industrial looped network module, a controller (MCU) and a logic control unit (CPLD) which are arranged in an FPGA module, a wireless 4G module and a data platform; the controller (MCU) is connected with the logic control unit (CPLD) through pins; the logic control unit (CPLD) is in transmission connection with the wired industrial looped network and the wireless 4G module through adopting serial ports; and the data platform is in TCP / IP network transmission connection with the wired industrial looped network module and the wireless 4G module. According to the system of the invention, 4G links are not adopted at ordinary times; when a network transmission fault occurs on an industrial looped network, the system can automatically switch in 4G wireless network communication; when the fault of the industrial looped network is removed, and normal communication is restored, wireless 4G signals are automatically cut off, and wired industrial looped network communication is restored. With the industrial looped network and 4G network automatic switching base station and the work method thereof of the invention adopted, automatic switching and automatic recovery of the industrial looped network communication and the 4G wireless network communication can be realized, and flexible requirements of different scenes for wireless communication can be satisfied, and traffic can be saved, and cost can be reduced.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to an automatic switching base station between an industrial ring network and a 4G network and a working method thereof. Background technique [0002] In the fields of large-scale chemical industry, factories and mines, wired or wireless networks are basically used for communication. The network cable and optical fiber communication signal are good, the transmission speed is fast, and stable, but the network cable and light wiring are difficult. If damage occurs and the line is disconnected, the base station cannot Connecting with the system will cause errors in the system and cause heavy losses; 4G wireless mode solves the problem of difficult cable laying in special areas, and provides mobile Internet, data communication and video services for large factories anytime and anywhere, and the wireless coverage scheme is flexible and easy to implement , Easy to maintain, but the...

[0002] In the fields of large-scale chemical industry, factories and mines, wired or wireless networks are basically used for communication. The network cable and optical fiber communication signal are good, the transmission speed is fast, and stable, but the network cable and light wiring are difficult. If damage occurs and the line is disconnected, the base station cannot Connecting with the system will cause errors in the system and cause heavy losses; 4G wireless mode solves the problem of difficult cable laying in special areas, and provides mobile Internet, data communication and video services for large factories anytime and anywhere, and the wireless coverage scheme is flexible and easy to implement , easy to maintain, but the investment is large and the cost is high. Due to the consideration of various factors such as cost, full coverage often becomes unrealistic, and the reliability of the system is also rapidly reduced.

Therefore, traditional methods are difficult to achieve low-cost redundant communication
