Description
Technical Field
[0001] The present invention relates to the field of simulation training, and more specifically to a simulation training method for inspection of a power communication room integrating virtual confrontation. Background Art
[0002] The inspection training of power communication room has long relied on the traditional training model. The training method usually relies on theoretical learning and field teaching, which has problems such as high cost, high risk and low efficiency, and it is difficult to meet the current needs of power communication inspection training. With the development of virtual reality technology in recent years, the training model of the power industry has ushered in a revolution, and virtual reality (VR) plays an important role in power training. Although virtual reality technology has improved these problems to a certain extent, most of them adopt a single, linear teaching method, which simply transforms traditional theoretical learning and field teaching into a virtual environment. Although this training method can provide a more realistic environment simulation, it ignores the fun and interactivity in the learning process. Employees are easily bored and tedious during long and repetitive operation exercises, resulting in poor learning results. At the same time, they lack enthusiasm and competitive awareness in the learning process, and think that virtual training is just a task, not a platform to improve their abilities and show their talents. This mentality will not only affect their learning results, but also their future career development.
[0003] Therefore, how to cultivate talents for communications companies still needs to be studied by technical personnel in this field. Summary of the invention
[0004] In view of this, the present invention provides a simulation training method for power communication room inspection that integrates virtual confrontation, aiming to introduce confrontation links and strategic props, improve the participation and learning interest of trainees, and thus stimulate employees' learning enthusiasm and competitive awareness. At the same time, the method is closely integrated with the talent training strategy of the telecommunications company, and the content is designed to design confrontation projects closely related to the actual work of power communication, such as room inspection, troubleshooting, computer networks, etc., so that employees can learn and practice in confrontation, ensuring that the training content and methods can fully meet the actual needs of the company, and cultivate talents with comprehensive capabilities and qualities for the company by promoting learning and training through competition.
[0005] In order to achieve the above object, the present invention adopts the following technical solution:
[0006] A power communication room inspection simulation training method integrating virtual confrontation includes an inspection mode, and the specific steps are as follows:
[0007] During the confrontation process, the path tracking method is used to obtain the coordinate information of the moving path point sequence of the confrontation students;

The moving trajectory of the confrontation student is discretized by the Newton interpolation method to obtain the corresponding position result of the confrontation student.

Obviously, the drawings described below are only embodiments of the present invention.

[0037] Figure 2 It is a relationship diagram between the quick-answer mode test questions of the present invention. DETAILED DESCRIPTION
[0038] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. 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.
[0039] The embodiment of the present invention discloses a simulation training method for power communication room inspection integrating virtual confrontation, such as Figure 1 As shown, including the inspection mode, the specific steps are as follows:
[0040] During the confrontation process, the path tracking method is used to obtain the coordinate information of the moving path point sequence of the confrontation students;
[0041] Abstract the coordinate information of the moving path point sequence into a Bezier curve, calculate the overall length of the Bezier curve, and determine the actual moving trajectory of the trainee;
[0042] The actual movement trajectory is compared with the ideal movement trajectory, and the students are scored based on the deviation results.
[0043] In the confrontation process of the inspection mode, the path tracking method is used to evaluate the confrontation students, obtain the coordinate information of the moving path point sequence of the confrontation students, abstract the path rules of the confrontation students into Bezier curves, and verify the compliance of the confrontation students' inspection paths through fitting and description.
[0044] The trajectory of the adversarial student is a Bezier curve of order n, and its calculation formula is:
[0045]
[0046] Where P i represents the coordinates of the adversarial student, corresponding to the i-th trajectory point, J i,n Represents the mixed basis function corresponding to the trajectory control point; represents the number of combinations; η represents the control parameter of the Bezier curve.
[0047] In order to ensure that the starting point and end point of the confrontation student meet the independent constraint conditions, the order of the Bezier curve is determined to be 3rd order. The planar motion trajectory of the confrontation student is calculated based on the curve of this order. The trajectory calculation formula is:
[0048]
[0049] Where x(η) and y(η) represent the horizontal and vertical positions of the opposing student, respectively.
[0050] By calculating the overall length L of the Bezier curve, effective planning of the path of the adversarial student is achieved. To ensure the accuracy of the solution, the control parameter η of the Bezier curve is first divided into N parts evenly, and then the result of L is calculated by the Simpson formula, which is:
[0051]
[0052] Where, d xy Represents the distance between x and y.
[0053] During the movement of the confrontation students, the smoothness of the movement speed is the core key factor to ensure the fairness of the confrontation students. Ensuring that the confrontation students complete the inspection target under the maximum allowed movement speed and acceleration conditions is the basis for ensuring the fairness of the confrontation mode. Therefore, after completing the path planning, it is necessary to plan the movement speed of the confrontation students. Under the premise of considering the acceleration constraint, the reference speed of the confrontation students is calculated. The calculation formula is:
[0054]
[0055] In the formula, It represents the maximum speed and maximum acceleration of the opponent student respectively; and j ref represent the maximum acceleration and reference acceleration respectively; T represents the control period; the moving trajectory length, reference speed, and reference acceleration of the kth discrete point at time T are represented by L ref (k), v ref (k), a ref (k) indicates.
[0056] Based on formula (4), we can obtain L ref The mapping relationship between (k) and η is calculated by Newton interpolation method, and then the movement trajectory of the confrontation student is discretized according to the calculation result to obtain the corresponding position result of the confrontation student. The ideal trajectory formula of the confrontation student is:
[0057]
[0058] In the formula, r represents the moving distance of the opponent student; (x r ,y r ) represents the desired coordinates of the opponent student, and combined with the desired angular velocity θ of the opponent student r , we can get the expected position of the opponent student at this time q = (x r ,y r ,θ r );v r represents the expected linear velocity; w r Represents the expected angular velocity. Based on the above content, the ideal moving trajectory planning of the adversarial student can be completed.
[0059] Afterwards, the confrontational students are dynamically positioned, and their actual movement trajectory is compared with the ideal movement trajectory plan, and the students are scored based on the deviation results.
[0060] A power communication room inspection simulation training method integrating virtual confrontation includes a quick-answer mode, and the specific steps are as follows: randomly selecting questions from a preset question bank within the scope of power communication room inspection and issuing them, the quick-answer questions in the entire confrontation link form an answer sheet, and the student's score is determined by the total score of the answer sheet.
[0061] In the quick-answer mode, questions need to be randomly selected from the preset question bank in the scope of the power communication room inspection, and the quick-answer questions in the entire confrontation phase will form an answer sheet. This patent designs the data structure based on random question selection. In the process of generating quick-answer questions, the three decisive factors are the test question attributes, the test paper parameters, and the question extraction algorithm.
[0062] The attributes of the test questions are set as test question number, test knowledge point, difficulty, cognitive classification, and remarks. In order to ensure a balance between knowledge coverage and difficulty coefficient, the test question bank needs to be classified and segmented: the question bank is classified according to the knowledge points of the power communication room inspection, and each category forms a segment. In the segment, it is further segmented according to the difficulty, cognitive classification and other attributes to solve the problem of knowledge point coverage and the problem of repeated questions.
[0063] The test paper composition parameters are the test paper composition structure formed when the questions are drawn, including the chapters and difficulty levels. They are parameters of the test question attributes.
[0064] The process of drawing questions and assembling papers can be summarized as the process of establishing a target state matrix, where A represents the composed test paper, a represents the test questions in the test paper, m represents the number of questions in the test paper, n represents the test question attribute index, and a represents the test question attribute index. mn represents the nth attribute parameter of the mth question, then the mathematical model for test paper generation is:
[0065]
[0066] After the mathematical model is established, the goal of drawing questions and setting the test paper can be achieved by simply solving the matrix A according to the test paper setting parameter requirements and the actual situation of the test question bank. The mathematical model of the test paper setting parameters needs to meet the following constraints.
[0067] Total score of the test paper M: The total score of the test paper formed by randomly selected questions in this competition.
[0068]
[0069] Test paper scores for each chapter V s : The score of the test questions covering the knowledge points of Chapter S, b is is the score of the i-th question in Chapter S.
[0070]
[0071] After that, a database is needed to store the test papers so that they can be distributed to the students in a rush-to-answer format at fixed nodes. Figure 2 shown.
[0072] The data structure of the question extraction algorithm consists of two parts. The first part is the chapter structure vector, each vector contains three pieces of information: chapter ID number, knowledge point ID number, and question list ID; the second part is the question ID list vector of each chapter. During the question extraction process, the system searches in the order of chapter, knowledge point, and question list, and extracts the corresponding question in each random segment.
[0073] In this specification, each embodiment is described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The same or similar parts between the embodiments can be referred to each other. For the device disclosed in the embodiment, since it corresponds to the method disclosed in the embodiment, the description is relatively simple, and the relevant parts can be referred to the method part.

Various modifications to these embodiments will be apparent to one skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but rather to the widest scope consistent with the principles and novel features disclosed herein.
