Abstract

This application discloses a network-type electro-hydraulic control system based on a double-layer network architecture, which relates to the field of mining equipment, including a composite function box, an electro-hydraulic control host, and a host computer; The network switch module includes an electrical network interface and an optical fiber network interface; each preset number of electro-hydraulic control hosts is connected in series with an inter-rack cable to form an electrical Ethernet subnet, and any electro-hydraulic control host in the electrical Ethernet subnet passes through The electrical network interface establishes an Ethernet data communication connection with the composite function box, which is used to upload communication data in the electrical Ethernet subnet to the composite function box; an optical fiber connection is established between the host computer and the composite function box through an optical fiber network interface to form a fiber optic Ethernet backbone The upper computer is used to process the communication data in the composite function box in the optical fiber Ethernet backbone network, and forward the processed communication data to the target electro-hydraulic control host.

Description

technical field [0001] The present application relates to the field of mining equipment, and in particular, to a network-type electro-hydraulic control system based on a two-layer network architecture. Background technique [0002] Commonly deployed systems in fully mechanized mining face include electro-hydraulic control system, visualization system, voice system, personnel positioning system, three-machine system, etc. to realize support control, audio access, video access, personnel and shearer positioning , Shearer control, scraper control, belt conveyor control, pump station control, etc. The systems generally operate independently, and there are also a few working faces. There is a small amount of linkage and blocking protection between the systems. [0003] At present, the network-type electro-hydraulic control system applied to the fully mechanized mining face integrates a multi-port switch inside the electro-hydraulic control host, and uses two 100M electrical inte...
