Embodiment 1

[0025] Such as figure 1 as well as figure 2 As shown, taking the AGV transportation task in the workshop as an example, the specific steps are as follows:

[0026] 1) The location information of the AGV is read through RFID technology. First, the AGV transportation path is divided into multiple small sections, and each small section is based on the RFID radio frequency card to ensure that there is a radio frequency card on each section; the current AGV transportation task is obtained through the host computer server The specific walking route of the AGV, so that the decomposed small path segments are sorted according to the task operation requirements; when the AGV reads the radio frequency card during operation, it predicts the next path that the AGV will take according to the current position information, and uses the radio frequency card number of the next path as Feedforward output;

[0027] 2) When the AGV reads the radio frequency card during operation, the AGV model ...

Embodiment 2

[0030] Taking the manipulator task in the workshop as an example, the specific steps are as follows:

[0031] 1) The manipulator is equipped with an angle sensor and a position sensor, which can accurately sense the current position and angle of the manipulator. Firstly, the action sequence of the manipulator is established according to the process requirements. During the operation of the manipulator, when the previous process action is about to end, it predicts the next action against the action sequence and outputs it as a feed-forward;

[0032] 2) When the last process action is about to end, the current position deviation is obtained according to the information of the real-time position sensor and angle sensor and the current coordinate position of the manipulator in the virtual scene, and the deviation is output as feedback;

[0033] 3) Combining the output of feedforward and feedback, the next action command of the manipulator model in the virtual scene is obtained. I...

Abstract

The invention discloses a matching method of real-time three-dimensional visual virtual monitoring for intelligent manufacturing. According to the method, three-dimensional virtual monitoring for an intelligentization manufacturing workshop is realized by virtue of the behavior state matching of feed-forward feed compound control and by virtue of real-time data. The method comprises the following steps: first decomposing action sequences of various monitored intelligent devices of a workshop, ranking the action sequences according to an operational logic, predicting a next action of a virtual model by virtue of a feed-forward control method, and carrying out optimization matching according to the state data fed back by the intelligent device in real time and in conjunction with a prediction action, thus obtaining a current movement instruction and driving a three-dimensional model. By adopting the method, the real-time performance and accuracy of the model action in the three-dimensional visual virtual monitoring can be effectively improved, the optimization of a virtual scene is realized, and the real-time performance and real-scene feeling of the three-dimensional virtual monitoring for the manufacturing workshop can be improved.

Description

technical field [0001] The invention belongs to the technical field of control methods, in particular to a matching method for intelligent manufacturing-oriented real-time three-dimensional visualization virtual monitoring. Background technique [0002] As an important technology in intelligent manufacturing, visualization has attracted more and more attention and attention in recent years. The essential difference between real-time 3D visualization virtual surveillance and video surveillance lies in two points: The first difference is that the physical scene represented by real-time 3D visualization virtual surveillance in the computer is realized by 3D modeling technology, so it is called "virtual surveillance". The Chinese invention patent "3D modeling method for digital workshop oriented to real-time virtual monitoring" (patent application number: 201510684216.9) details how to carry out 3D modeling technology oriented to real-time virtual monitoring; the second differen...
