Therefore, a user does not need to learn the polycrystalline silicon production operation in an actual production scene, the cost is saved, the possible danger of the actual production scene is avoided, and the safety is improved.
On the basis of the above embodiment, according to a specific implementation manner of the present disclosure, the polysilicon production scenario includes a silicon rod production scenario, the production plant model includes a reduction plant model and a reduction furnace model, the operation equipment model includes a mechanical arm model, and the polysilicon model includes a silicon rod simulation production process model;
the step of calling the preset model to build the simulation scene corresponding to the polycrystalline silicon production scene comprises the following steps:
calling the reduction plant model to build an analog simulation plant;
calling the reduction furnace model and the mechanical arm model to respectively build an analog simulation reduction furnace and the analog simulation mechanical arm in the analog simulation plant;
and calling the silicon rod simulation production process model to build a silicon rod growth model on the simulation reduction furnace.
In the embodiment, the targeted simulation is performed according to the production scene of the silicon rod in the polysilicon production, particularly the dismounting scene in the reduction furnace. The production plant model comprises a reduction plant model and a reduction furnace model which are respectively used for building an analog simulation reduction plant and an analog simulation reduction furnace. The silicon rod model is a silicon rod which is commonly used in the operation of disassembling and assembling the silicon rod, and is used for building an analog simulation silicon rod. The polysilicon model comprises a silicon rod simulation production process model which is used for building a silicon rod growth model on the simulation reduction furnace and simulating the whole process from production to disassembly of the simulation silicon rod according to a growth axis.
Optionally, the step of calling the silicon rod simulation production process model to build a silicon rod growth model on the simulation reduction furnace may include:
and simulating the whole growth period from charging to maturing of the silicon rod by using a finite element analysis method and a fluid dynamics combined simulation technology.
In the embodiment, the simulation of the silicon rod is performed by using a finite element analysis method and a fluid dynamics combined simulation technology. The Finite Element Analysis (FEA) is a method of simulating real physical systems such as geometric and load conditions by using mathematical approximation. With simple and interacting element elements, a finite number of unknowns can be used to approximate a real system of infinite unknowns.
The growth process of the silicon rod is simulated by combining a finite element analysis method and a fluid dynamics combined simulation technology, the calculated amount is less, and the growth period of the simulated silicon rod according to the time axis is simulated truly and proportionally.
Correspondingly, the step of acquiring a first parameter corresponding to the interaction of the target user with the preset model in the simulation scene may include:
collecting action parameters of the target user operating the mechanical arm model to disassemble and assemble the silicon rod in the simulation scene and time nodes corresponding to each action;
the step of comparing the first parameter corresponding to the interactive action with the second parameter corresponding to a preset standard action and judging whether the interactive action of the target user meets the production standard or not comprises the following steps:
comparing the action parameter and the time node corresponding to each action with the action parameter and the time node of each preset standard action, and judging whether the action parameter difference value and the time node difference value are within a preset difference value range;
if the action parameter difference value and the time node difference value are both within a preset difference value range, judging that the interactive action of the target user meets the production standard;
and if the action parameter difference value or the time node difference value is not within the preset difference value range, judging that the interactive action of the target user does not meet the production standard.
In this embodiment, the simulation process is further limited. In the whole period from charging to maturing of the silicon rod, an operator needs to operate the mechanical arm to load and unload the silicon rod, the silicon rod needs to be loaded and unloaded in a clean environment and cannot be released from other objects, and the growth state of the silicon rod needs to be judged according to the simulated growth environment of the silicon rod to determine the time node for loading and unloading the silicon rod.
When the interactive action is collected, action parameters of a target user for disassembling and assembling the silicon rod and a time node corresponding to each action need to be collected, and then the collected action parameters and the corresponding time nodes are compared with action parameters and time nodes of a preset standard action to obtain corresponding action parameter difference values and time node difference values so as to judge whether the action parameter difference values and the time node difference values are within a preset difference value range. And if the action parameter difference value and the time node difference value are both within a preset difference value range, judging that the interactive action of the target user meets a preset production standard. If at least one of the action parameter difference value and the time node difference value is not within the preset difference value range, the interactive action of the target user can be directly judged to be not in accordance with the production standard.
Therefore, the silicon rod production axis can be subjected to targeted simulation and interactive action detection of a user, and the adaptability is stronger.
Further, after the step of determining that the interaction of the target user does not meet the production standard if the action parameter difference or the time node difference is not within the preset difference range, the method may further include:
and outputting error prompt information and guide information to guide the target user to complete the interactive action, wherein the error prompt information and the guide information comprise voice information and/or image information.
In this embodiment, the determination of the limiting standard may be a continuous operation, that is, whether the current interaction action of the target user meets the production standard may be continuously detected in the process of simulating the silicon rod dismounting action by the target user. When the interactive action of the target user is detected to be not in accordance with the production standard, the error prompt message and the guide message are output to guide the target user to finish the interactive action, so that the influence of multiple interruption on the simulation efficiency can be avoided, the target user can learn operation in a simulation scene as much as possible, and the simulation effect is improved.
In addition, referring to fig. 2, an interactive schematic diagram of an analog simulation system of a polysilicon production scenario (hereinafter, the analog simulation system is referred to) is provided for the embodiment of the present disclosure, and the analog simulation system may be used to execute the analog simulation method provided by the embodiment shown in fig. 1.

Because the actual silicon rod growth period is long, the time axis can be freely dragged when a silicon rod growth model is established, after the standard model is established, the parameter floating range is set, and corresponding scores are set in different ranges. And setting corresponding standard models and scores in different operation steps to form a set of standard operation process.
