Abstract

The invention discloses a network type electro-hydraulic control system based on a double-layer network architecture, which relates to the field of mining equipment and comprises a composite function box, electro-hydraulic control hosts and an upper computer, wherein a backbone network switch module is integrated into the composite function box, and comprises an electric network interface and an optical fiber network interface; inter-rack cable series connection is established between every preset number of electro-hydraulic control hosts to form an electric Ethernet subne; any one electro-hydraulic control host in the electric Ethernet subnet establishes Ethernet data communication connection with the composite function box through the electric network interface and is used for uploading communication data in the electric Ethernet subnet to the composite function box; optical fiber connection is established between the upper computer and the composite function box through the optical fiber network interface to form an optical fiber Ethernet backbone network; and the upper computer is used for processing communication data in the composite function box in the optical fiber Ethernet backbone network and forwarding the processed communication data to a target electro-hydraulic control host.

Description

technical field [0001] The present application relates to the field of mining equipment, in particular to a networked 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 machine control, belt conveyor control, pumping station control, etc. The systems generally operate independently, and there are also a few working surfaces, and there are 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, uses two 100M electri...
