Abstract

The invention discloses a large-scale road maintenance machinery network control system and a design method thereof. The system comprises a main control module, a centralized control module, a display module, an Ethernet switch and a plurality of I/O modules. The main control module, the centralized control module, the display module and the Ethernet switch form a train-level network. The main control module, the centralized control module and the display module form an in-vehicle network. The main control module, the centralized control module and the plurality of I/O modules form an I/O sub-network. A three-level control network is composed of a train-level network, an in-train network and an I/O sub-network so as to realize decentralized control of running and operation functions of the large-scale road maintenance machinery. According to the invention, the technical problems of high cost of extended input and output points, complex secondary construction of a system network structure and low hardware cost performance of an existing large-scale road maintenance machinery network control system based on a two-stage network can be solved.

Description

technical field [0001] The invention relates to the technical field of railway engineering machinery, in particular to a three-level network-based large-scale road maintenance machinery network control system and a design method thereof.
