According to project experience, one of the main tasks of developing equipment virtual training simulators is to build training subjects.

The IDEF modeling method is a method based on structured design and analysis techniques and activity models, and is widely used. However, due to its more abstract nature, it is difficult to directly apply it to specific areas in actual applications. IDEF is only a description method, and there is no related software framework that can be used in software engineering.

Based on the above problems, an equipment virtual training modeling method is provided in an embodiment of the present application, and a new software framework is applied to equipment virtual training. The main work is changed from the previous program coding to defining XML files, so that the center of the entire development process is changed from code to business logic, which can reduce the development workload of the equipment virtual training system by 70%, greatly improve the development efficiency, reduce software defects caused by coding, greatly shorten the development cycle, and reduce development costs.

In order to enable those skilled in the art to better understand the solutions of the present invention, the technical solutions in the embodiments of the present application are clearly and completely described below. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

FIG. 1 is a schematic flow chart of an equipment virtual training modeling method provided by an embodiment of the present application. Referring to FIG. 1 , the equipment virtual training modeling method is described in detail as follows:

In step 101, an XML script file of equipment failure maintenance training subjects is defined according to predefined equipment failure maintenance rules.

In order to support the operation of equipment virtual training, the training subjects are defined as an XML file using XML syntax. XML syntax itself supports multi-level parent-child relationships, which is consistent with the definition of steps. The parent-child relationship in the XML file is converted into the parent-child relationship of the step.

In step 102, the script parser is called by the process management module to parse the XML script file and obtain the script content; the script content includes initialization information, steps, conditions, actions and status values.

The initialization information includes information such as objects (buttons) in the component bar and spare parts bar. The script parser also parses the object definitions of the component bar and spare parts bar to generate the objects in the component bar and spare parts bar. The properties of the object include name, icon, name and time.

Among them, the equipment virtual training modeling framework includes five elements: step, event, condition, action and state value.

Among them, a step is a definition of a group of operations or a step of operation in the equipment maintenance process. It can also be a step of operation that is automatically executed or notified by an external system. Steps are divided into logical steps and combined steps. Logical steps accept events, make logical judgments based on conditions, and start to execute their actions after the judgment conditions are passed. Combined steps can contain multiple sub-steps, which control the execution of sub-steps in terms of execution order and execution flow. The above sub-step types can be the same or different.

For example, "Use a screwdriver to unscrew the screws on the front cover" is an operation in this step, "Unscrew the three plugs A, B, and C respectively" is a group of operations, and "Wait for the S car to issue a launch command and launch a missile" is an operation notified by an external system. They can all be defined as a step.

Exemplarily, each time the process management module calls a step, it returns a call result, such as a tool error, an object error, a correct operation, an invalid operation, etc.

Among them, events are defined as external inputs, including user operation inputs or messages or instructions sent by other subsystems through the network; events are generated by event providers.

For example, clicking on an object in the scene and clicking on an object on the interface are both events.

Among them, conditions belong to logical steps and are the judgment rules of the steps.

For example, "the mouse clicks on XXX object" is a condition. Conditions are used to match the currently generated events. A step can contain multiple conditions. When all conditions are met, the step starts to execute the action through logical judgment.

Exemplarily, the event type and the condition type have a corresponding relationship, and their parameters are also the same.

Exemplarily, the condition includes selecting a 3D object and a 2D object, that is, if the event matches the preset condition, the type of the selected object should be consistent.

Exemplarily, the parameters for selecting the 3D object condition include the name of the tool and the 3D object, such as using a “screwdriver” to unscrew a “screw”.

Among them, action refers to the output generated by the virtual scene after the correct operation steps, including equipment fault repair training animation actions and updated status values.

For example, after the user tightens the screw, the performance action is animated to show the process of "the screw gradually rotates outward and then hides". The action is a continuous execution process, so during the execution of the action, the state of the step will be set to "executing the action".

For example, an animation action has multiple sub-actions built in, including: rotation and translation, translation, rotation, zooming, 360° rotation, quaternion rotation, visibility, indicator light on, indicator light off, indicator light flashing, object flashing, etc. An animation action includes a start time field, which allows the animation to not be executed immediately after activation, but to wait for a period of time before starting to execute. Using the above fields, multiple animation actions can be combined more conveniently so that the preset actions are executed in sequence.

For example, updating the state value to text and the state value operation often appear together and are placed after the state value operation to display the value of a certain state value on a text object in the scene.

For example, some combination panels include a display screen, and by pressing a button, the content of the display screen is modified. The state value is modified by pressing the button, and the state value operation action is implemented. After the state value is modified, it is also displayed on the display screen, which is implemented by updating the state value to text.

Specifically, the process management module calls the script parser to parse the XML script file, including: according to the path of the script file of the corresponding equipment fault maintenance training subject, the process management module calls the script parser to obtain the parsed script content; based on the initialization information, initializes the UI and three-dimensional scene of the corresponding equipment fault maintenance training subject; based on the UI and three-dimensional scene, registers the event provider.

In step 103, based on the parsed script content, the steps of the equipment fault maintenance training subject are updated; the process management module schedules and manages the operation steps of the equipment fault maintenance training according to the preset scheduling rules.

Specifically, based on the parsed script content, the steps of the above equipment failure maintenance training subject are updated, including:

The process management module registers the Update function; the process management module uses the Update function to traverse the event provider and obtain a list of new events in the current frame; the new event is an external input event collected by the event provider; in the list of new events, an empty event is inserted; the empty event is generated in each frame of the system operation and passed to the unconditional operation step; the process management module obtains the first state of the current step of the equipment fault maintenance training subject, and if the current step is in an inactivated state, activates the current step; the first state of the step includes activated and inactivated.

If the current step is in the activated state, the process management module calls the Update function cyclically according to the preset time period to update the steps of the equipment fault maintenance training subject; the process management module calls the Update function to match the new event with the conditions of the current step of the equipment fault maintenance training subject; after the matching is completed, the corresponding action of the step of the equipment fault maintenance training subject is updated.

The above step status definitions are inherited by all subtype steps. Each step has only one of the above statuses at a certain moment.

Specifically, after the matching is completed, the corresponding actions of the step of updating the equipment failure maintenance training subject include:

After the matching is completed, the second state of the current step of the equipment fault maintenance training subject is obtained; the second state of the current step includes executing the action and completing the execution; based on the obtained second state of the current step, the corresponding action of the current step of the equipment fault maintenance training subject is updated.

Update the corresponding actions of the current step of the equipment failure maintenance training course, including:

If the current step status is completed, the current step update of the current frame is ended; if the current step status is in execution, the process management module is waited for the next frame to call the Update function to update the next step of the equipment fault maintenance training subject.

When the process management module calls the Update function in the next frame to update the next step of the equipment failure maintenance training subject, the next step is the current step.

Specifically, after the matching is completed, the corresponding actions of the steps of the equipment fault maintenance training subject are updated, and also include: according to the step type of the equipment fault maintenance training subject, updating the corresponding actions of the current step type; the step type of the equipment fault maintenance training subject is a pre-set step type corresponding to the new event, and the pre-set step type includes: abstract logic steps, combination steps; the abstract logic steps include logic steps and loop steps; combination steps include serial combination steps and parallel combination steps; parallel combination steps include parallel all steps, parallel specified steps and parallel random steps.

The corresponding actions of the steps of the equipment failure repair training subject include equipment failure repair training animation actions and updating status values.

Among them, in order to make the step classification hierarchy reasonable, the abstract logic step abstracts the common attributes and methods of the logic step and the loop step; the combination step abstracts the common attributes and methods of the "step combination", and the combination step includes a sub-step list that stores the sub-steps belonging to the step.

As shown in FIG2 , for a logic step, corresponding actions for advancing the logic step include:

Get the step status of the equipment fault maintenance training subject; if the step status of the equipment fault maintenance training subject is in execution, advance all actions corresponding to the steps of the equipment fault maintenance training subject; after advancing all actions corresponding to the steps of the equipment fault maintenance training subject, determine whether all actions corresponding to the steps of the equipment fault maintenance training subject have been fully executed; if all actions corresponding to the steps of the equipment fault maintenance training subject have been fully executed, set the operation steps of the equipment fault maintenance training subject to completion; if all actions corresponding to the steps of the equipment fault maintenance training subject have not been fully executed, end the current action update; all actions corresponding to the steps of the equipment fault maintenance training subject include equipment fault maintenance training animation actions and update status values.

If the step status of the equipment fault maintenance training subject is activated, determine whether the new event matches the conditions of the step of the equipment fault maintenance training subject; if the new event matches the conditions of the step of the equipment fault maintenance training subject, activate all corresponding actions of the step and set the step status to executing action; if the new event does not match the conditions of the step of the equipment fault maintenance training subject, exit this step update.

Exemplarily, there are tool 1 and tool 2, accessory 1 and accessory 2, and the preset condition is that tool 1 clicks accessory 1, and tool 2 clicks accessory 2; if the user uses tool 1 to click accessory 2, and tool 2 clicks accessory 1, the new event does not match the conditions of the steps of the equipment failure maintenance training subject; if the user uses tool 1 to click accessory 1, and tool 1 to click accessory 2, the new event still does not match the conditions of the steps of the equipment failure maintenance training subject, and this step update is exited; only when tool 1 clicks accessory 1 and tool 2 clicks accessory 2, the preset condition is met, all corresponding actions of the current step are activated, and the step status is set to executing action, and the next action is continued.

As shown in FIG3 , for the loop step, the corresponding action of advancing the loop step includes:

Get the step status of the equipment fault maintenance training subject; if the step status of the equipment fault maintenance training subject is in execution, advance the corresponding action of the step of the equipment fault maintenance training subject; after advancing the corresponding action of the step of the equipment fault maintenance training subject, determine whether the corresponding action of this step has been fully executed; if the corresponding action of the step of the equipment fault maintenance training subject has been fully executed, set the current step to complete; if all actions have not been completed, end the current step update.

If the step status of the equipment fault maintenance training subject is activated, advance the sub-steps of the step of the equipment fault maintenance training subject, and update all conditions corresponding to all actions, all conditions include preset step results and preset conditions; make a judgment based on the sub-step results and conditions. If the sub-step results meet the preset step results and the conditions meet the preset conditions, activate all actions and set the step status to executing actions.

Exemplarily, there are existing tools 1 and tool 2, accessory 1 and accessory 2, and a display, and the preset condition is that tool 1 clicks accessory 1, tool 2 clicks accessory 2, and the display displays the value m; if the user uses tool 1 to click accessory 1 and tool 2 to click accessory 2, and the display displays a result value of n after the operation, n and m are not equal, and the preset condition is not met; if the user uses tool 1 to click accessory 1 and tool 2 to click accessory 2, and the display displays a result value of n after the operation, n and m are equal, then the preset condition is met, all corresponding actions of the steps of the equipment fault maintenance training subject are activated, and the step status of the equipment fault maintenance training subject is set to executing action, and the next action is continued, that is, all conditions are met, including simultaneously meeting the preset step results and preset conditions; the above preset conditions are the conditions of the steps of the equipment fault maintenance training subject.

As shown in FIG4 , for the serial combination step, the corresponding action of advancing the serial combination step includes:

Get the step status of the equipment fault maintenance training subject; if the step status of the equipment fault maintenance training subject is inactive, exit the step execution of the equipment fault maintenance training subject; if the step status is activated, get the current sub-step; if the sub-step status is inactive, activate the sub-step, and call the sub-step update; determine whether the current sub-step has been updated; if the current sub-step is not completed, exit the step execution of the equipment fault maintenance training subject; if the current sub-step has been completed, determine whether all sub-steps have been completed; if all sub-steps are not completed, add one to the current sub-step; if all sub-steps are completed, the serial combination step is completed.

It should be understood that a serial combination step is to execute a group of sub-steps one by one in sequence.

As shown in FIG5 , for the parallel combination step, the corresponding action of advancing the parallel combination step includes:

Traverse the sub-steps of the equipment failure maintenance training subject; determine the status of the sub-steps, if the status of the sub-steps of the equipment failure maintenance training subject is not activated, activate the sub-steps of the equipment failure maintenance training subject; advance the sub-steps; after traversing all the sub-steps, if the status of the sub-steps that must be completed is completed, the parallel combination steps of the equipment failure maintenance training subject are completed; the above-mentioned sub-steps that must be completed can be all sub-steps, specified sub-steps or random sub-steps.

For example, in the disassembly process, A can be disassembled first, or B can be disassembled first. Disassembly of A requires three steps, and disassembly of B requires three steps. The three steps of disassembly of A can be organized into a serial combination step, and the three steps of disassembly of B can also be organized into a serial combination step, and then the two serial combination steps can be organized into a parallel combination step. In this way, during the training process, the order of disassembly of A and B is no longer fixed, which increases flexibility. The serial combination step is usually used to organize sub-processes as sub-processes of the parallel combination step.

Exemplarily, for the above situation, the two combinations of A and B can be disassembled at the same time. A can be disassembled first and then B, or B can be disassembled first and then A, or the two sub-processes can be performed alternately.

Exemplarily, in the parallel combination step, all sub-steps are activated at the same time and can be executed in parallel. According to different ending conditions, it can be divided into parallel all steps, parallel specified steps and parallel random steps. Parallel all steps means that all sub-steps are activated and executed at the same time, and the step is not completed until all sub-steps are completed; parallel specified steps means that all sub-steps are activated and executed at the same time. When a specified sub-step is completed, the step is completed regardless of the execution status of other sub-steps; parallel random steps means that all sub-steps are activated and executed at the same time. When the parallel random step is activated, a random number is generated. The random number is used to specify the sub-step. When the specified sub-step is completed, the step is completed.

For example, for the same fault phenomenon, there may be two fault causes. In order to prevent the training process from becoming rigid, the fault cause changes randomly during each training. Through parallel random steps, a maintenance process required for one fault cause is randomly selected. Only after the maintenance process is completed, the subject training is completed.

Specifically, the process management module includes a training subject serial combination step; a training subject serial combination step is used to store all operation steps of equipment fault maintenance training; the operation steps have multiple step types, which are nested with each other according to preset relationships of different types of steps.

It should be understood that the size of the serial numbers of the steps in the above embodiments does not mean the order of execution. The execution order of each process should be determined by its function and internal logic, and should not constitute any limitation on the implementation process of the embodiments of the present application.
