The function is the real-scene management of various MES systems in the factory. Since the model built in the planning stage is realistic, and the optimization scheme is obtained after simulation verification and implemented according to the optimization scheme, the current model and the actual state of the enterprise are perfectly unified statically.
We continue to exploit this functionality, if the enterprise uses the MES system, then the shop data has already been collected and the processing application is running.

In practical application, the software cannot completely and independently realize the unmanned factory, but is absolutely a new idea and solution tool for realizing the unmanned factory. Functions that are relatively easy to implement include:
1. equipment inspection: through the combination of various sensors and cameras, the virtual space is patrolled and examined to the equipment management personnel accessible VR equipment entering. All the relevant parameters of the equipment are displayed in the virtual space and can be recorded in real time. If the alarm occurs, the manager can also directly control the related equipment in the virtual space to adjust the parameters, so that the equipment can not be patrolled and examined on site, and meanwhile, the equipment manager can be familiar with the site environment, and the situation that the equipment cannot enter the site to remove the fault quickly when the actual site operation is needed is avoided.
2. Emergency drilling: for some conditions which cannot be really exercised, such as earthquakes, fires and the like, relevant environments can be set, so that the staff can verify the accuracy of an emergency plan and exercise the emergency capacity of the staff in virtual reality. Because the environment and the real scene are both 1: 1, the replication and even the production status are the same as those in emergency, and the method has good effect on the emergency capacity cultivation of the staff.
3. Skill training: particularly, new employees enter the office, aiming at some dangerous work types, a virtual reality is directly copied according to the current production situation, the employees are trained on the premise of not influencing the real reality, or the operation skills of the employees are verified, and whether the actual influence is generated on a factory or not is judged.
