Abstract

The invention provides a metal rolling process automatic control hardware-in-loop simulation platform and method for an experiment. The platform comprises a process control level, a basic automation level and a device simulation level. The process control level is connected with the basic automation level through the Ethernet. The basic automation level is connected with the device simulation level in a hardwired mode. The process control level and the basic automation level are consistent with an industrial site in the aspect of configuration of hardware and software. According to the metal rolling process automatic control hardware-in-loop simulation platform and method for the experiment, the method of combining real objects and a simulation model is adopted, and compared with an experiment rolling machine, under the condition that device investment is greatly reduced, the purpose of reappearance of a site actual control system is achieved; compared with pure computer software simulation, a real-time control layer which is necessary in industrial process control is additionally arranged, so that the control structure of the platform is more similar to the control structure of the industrial site; in addition, a control system and a simulation rolling device are connected in the hardwired mode, and the communication connection mode of the actual industrial site directly reappears in a non-industrial site.

Description

technical field [0001] The invention belongs to the field of automatic simulation experiments of metal rolling process, and in particular relates to an experimental metal rolling process automatic control hardware-in-the-loop simulation platform and method. Background technique [0002] The rolling process of metal is a typical process industry rolling process, which has the characteristics of complex, high-speed, multi-variable, time-varying, etc. Usually, a lot of debugging work is required before the rolling mill is put into rolling operation; at the same time, although the rolling mill control system The basic equipment is technically mature, and the basic rolling automation has been realized, but there are still many theoretical and practical issues waiting to be studied and solved. To solve these problems, a large number of actual testing work based on rolling equipment is also required. However, in actual situations, due to factors such as equipment, processing materi...
