Abstract

The invention discloses a network control system of a large road maintenance machine. The system comprises 1-n bottom modules, 1-t network modules and 1-m display modules, wherein the modules are interconnected through a field bus network; each bottom module comprises a power module, a pulse recognition module, a main digital input module, a gateway module, a main analog input module and a main digital output module which form a communication backbone network as well as a digital input extension module, an analog input extension module and a digital output extension module which form a communication I / O subnetwork. The communication I / O subnetwork is extended by any one or more of the main digital input module, the gateway module, the main analog input module and the main digital output module. The technical problems that the cost of extended input and output points of existing systems is higher, secondary construction of the system network structure is complicated and the cost performance of hardware is low can be solved.

Description
