Abstract: Current communication network system of electro-hydraulic control system of hydraulic support adopts no host control method to transmit data, and data generation time, generation quantity and delivery time has uncertainty，so as to cause communication network system is like a "black box" for users. In order to solve the above problems, a design scheme of transparent communication network system of electro-hydraulic control system of hydraulic support was put forward. The system can understand interconnection performance of equipment through communication state diagram, understand usage of equipment communication resources through traffic view, and know availability of device communication resources and management of communication routing pipelines through fault views. The system uses intuitive and visual way to display real-time performance and fault view of communication network of electro-hydraulic control system of hydraulic support for users, and makes the system transparent. The communication network system can also clearly understand the running status of electro-hydraulic control system of hydraulic support, and find problems existed in communication network timely.
