The specific process is as follows:
1) a DB module special for displaying pictures is established in a PLC program, and equipment state data needing 3D display is stored in the DB module, such as the running state of a motor, the material state of a production line, the opening and closing states of a valve and an air cylinder, and the working states of an expanded cut tobacco impregnator and a sublimation device (shown in figure 8).

And reading the temporary file data by using the Updata function of the Unity3D, and updating the picture to realize the synchronization of the picture data and the PLC data. In this way, the temporary file data is read by using the Updata function of Unity3D, and the picture is updated, so that the picture data and the PLC data are synchronized.
As shown in fig. 7, OPC uses a typical C/S mode to establish a data acquisition channel of the PLC, and the acquired process data further includes parameters such as Value, Quality, Timestamp, and the like; fig. 9 and 10 are partial human-computer interaction cross sections. In the configuration software, the visual angle of a picture is fixed, the random change of the visual angle cannot be realized, the checking of different fixed visual angles can only be realized by switching the picture, and the visual angle of the Unity3D is acquired by one picture camera. And obtaining mouse click through an input and GetMouseButton function to realize the calling of the sub-picture and the reading of various parameter interfaces.
The traditional monitoring software adopts 2D materials to make pictures, so that the actual position of the equipment is relatively abstract on the picture display, and the traditional monitoring software is very unfriendly to new staff. According to general experience, a newly entered staff needs to exercise for more than three months on a local operation post at least to skillfully combine the equipment type and equipment parameters of a picture with local actual equipment to make accurate judgment on various emergencies in production, and the complete familiarity with a production line usually needs half a year or even longer. Use neotype inflation pipe tobacco three-dimensional visual dynamic monitoring system, can effectual improvement staff's learning efficiency, it is with first person's visual angle free choice and look over equipment, can be consistent with on-the-spot actual conditions, great deepening new staff's impression, make it can be faster master operating skill. According to the performance of a plurality of new employees who use the new system, the employees only spend one month to reach the level of the previous three months, the efficiency is greatly improved, and the labor cost is saved. According to the salary calculation of each employee, the cost can be saved by 1 ten thousand yuan for each employee training.
Although the embodiments of the present invention have been shown and described above, it is understood that the above embodiments are exemplary and not to be construed as limiting the present invention, and those skilled in the art can make changes, modifications, substitutions and alterations to the above embodiments without departing from the principle and spirit of the present invention, and any simple modification, equivalent change and modification made to the above embodiments according to the technical spirit of the present invention still fall within the technical scope of the present invention.
