Abstract

The invention discloses a multi-channel switching control method and device in a heterogeneous industrial network environment. According to the multi-channel switching control method and device in the heterogeneous industrial network environment, an industrially applied communication mode in the scene can be borne by a complex heterogeneous network, a business side can deploy a specific application independent of a specific communication technology, and business applications can be subjected to seamless switching in different network environments. Through the multi-channel switching control method and device in the heterogeneous industrial network environment, reliability and real-time performance of communication can be improved, and flexibility, reliability and real-time performance of business application deployment are improved. The multi-channel switching method and device realize switching control of multiple channels jointly by depending on not only interactive measurement between a terminal and a network, but also combined judgment of multilayer state acquisition and multiple strategies on a provided network and multiple control modes.

Description

technical field [0001] The invention relates to the related fields of industrial control and communication technology. Background technique [0002] With the continuous development of computer technology, communication technology and information technology, there are more and more types of computer networks. Communication methods in the consumer field such as 2G, 3G, 4G, ADSL, EPON / GPON, WIFI, Bluetooth and other technologies have been widely used. The communication methods used in industrial environments (such as electric power, energy, transportation, etc.) are becoming more and more abundant. Various wired and wireless networks such as Ethernet, optical network, wireless local area network, 2G / 3G / 4G public network, and industry private network , public network, and private network are integrated and complement each other. In the case of the coexistence of many communication modes, the user's choice of network tends to be heterogeneous integration. However, to integrate...
