Problems solved by technology

[0003] However, in the existing process control technology of the process industry, there are mainly two-dimensional control charts, and seldom involve the interactive control of the three-dimensional environment
It is difficult to effectively combine the simulation system that reflects real-time data changes and the virtual reality system that reflects industrial scenes, and cannot exert greater synergy

Embodiment Construction

[0061] figure 1 It is a flow chart of the interactive control method for key equipment in the process industry based on virtual reality of the present invention.

[0062] The method process is as follows:

[0063] First, use 3DS MAX in the virtual reality 3D scene system to establish a 3D model of the reactors, regenerators, measuring instruments, control valves, inlet and outlet side lines, etc. involved in the refinery, and then establish a dynamic model for the simulated operation of the device. Through the virtual reality man-machine The interactive interface sets different production operation interference modes, control parameters, simulation start and end times, and writes production control instructions into the database. Next, the dynamic simulation system reads the instruction parameters, runs the simulation model, and writes the production operation data (including device temperature, pressure, material level, flow, etc.) involved in these models into the correspon...

Abstract

The invention discloses a method for the interactive control on key devices in a process industry on the basis of virtual reality. The method comprises the following steps of: 1) establishing a virtual reality system, a dynamic simulation system and a database system; 2) setting the instructions for operating the key devices and controlling the dynamic parameters in the virtual reality system, writing the instructions into the database system, and monitoring the instructions in the database system by the dynamic simulation system at the same time; 3) when an operation instruction is monitored, reading the initial simulation parameters of the key devices from the database system, carrying out the dynamic simulation and writing the simulation results into the database system; and 4) reading the simulation results from the database system, presenting the changing process of the production data of the key devices in the virtual reality system and carrying out the real-time control. By presenting and controlling the changing process of the production and operation on the basis of the visualization technology, the invention can provide effective information support for users to monitor the production and operation on a real-time basis, help simulate and predict the process control layer in the process industry and improve the benefit of the operation in enterprises.

Description

technical field [0001] The invention relates to the field of computer technology, in particular to a virtual reality-based interactive control method for key equipment in the process industry. Background technique [0002] Most of the equipment in the process industry must operate continuously, usually in an environment of flammable, explosive, high temperature and high pressure. The system model is fully simulated and simulated by means of computer simulation to simulate the operation process of the actual system. Statistical analysis of observed and output data in a 3D scene to infer the true parameters and performance of the system under study or designed. With the support of virtual reality technology, modelers and decision makers can not only obtain various important simulation data, but also see the corresponding 3D simulation animation during the simulation operation, thus providing intuitive and realistic system operation , help them understand and recognize the nat...
