Abstract

The invention discloses a large-scale road maintenance machine network control system design method. The method comprises the steps of: enumerating types and numbers of input / output signals of a system according to an applied vehicle model control function; configuring the number of each module in the system according to the types and the numbers of the signals and application of the signals; configuring the number of a power module; configuring the number of a gateway module; distributing a digital input signal, a digital output signal and an analog input signal in the system to the corresponding modules; distributing a meter display signal and an alarming display signal in the system to a display module; writing application programs of the corresponding modules to realize logical relationships of various input / output; writing a top application program of the display module to display a meter signal and an alarming display; and writing a bottom application program of the display module to realize control and diagnosis operations of the corresponding modules. Through adoption of the method provided by the invention, technical problems in an existing method that the input and output point extending cost is higher, secondary construction of a system network architecture is complicated, and the cost performance of hardware is not high, are solved.

Description

technical field [0001] The invention relates to the field of railway engineering machinery, in particular to a method for designing a network control system of large-scale road maintenance machinery based on a two-stage CAN network. Background technique [0002] As the core technical field of railway track maintenance engineering machinery, the electrical system of large-scale railway track maintenance machinery is responsible for various operations and auxiliary control tasks of the whole vehicle. It is the brain of the whole vehicle and directly directs various operations, running and braking actions. From the perspective of electrical control, it involves many aspects such as analog control, digital control, computer software, hardware, electrical control, and laser technology. [0003] In the prior art, the closest to the application of the present invention is the invention filed by the applicant and Zhuzhou CSR Times Electric Co., Ltd. on March 14, 2012, and announced ...
