Description

Technical Field

[0001] This application relates to the field of simulation technology, specifically to a banquet hall simulation teaching system based on a 3D virtual hotel scene. Background Technology

[0002] The ability to manage, operate, arrange, and handle emergencies in banquet halls is a crucial skill for university students majoring in hotel management. Currently, teaching these skills often relies on hands-on practice, which has several drawbacks. Hands-on teaching requires real banquet hall resources, increasing teaching costs and making it difficult to simulate various hygiene and equipment malfunctions, resulting in a limited teaching scenario. Changing banquet or conference setups on-site consumes significant manpower, resources, and time, leading to inefficiency and hindering rapid comparison of different setups. Furthermore, conducting emergency drills such as fire escape exercises on-site poses safety risks, fails to realistically simulate the complexities of a fire scenario, and is difficult to repeatedly conduct to strengthen students' emergency response capabilities.

[0003] With the development of 3D virtual simulation technology, its application in the field of education has become increasingly widespread. Applying 3D virtual simulation technology to banquet hall-related teaching can effectively solve the problems existing in on-site teaching. However, current technology lacks a comprehensive banquet hall simulation system specifically designed for school teaching scenarios. It cannot simultaneously achieve integrated teaching functions such as supervision and inspection, fire escape, banquet DIY, and meeting setup simulation, and it also has shortcomings in the interactive logic of each function, scene adaptability, and teaching practicality. Therefore, there is an urgent need for a banquet hall simulation teaching system based on a 3D virtual hotel scene to meet the teaching needs of related majors in universities. Summary of the Invention

[0004] In view of the shortcomings of the existing technology, the purpose of this invention is to provide a banquet hall simulation teaching system based on a 3D virtual hotel scene to solve the problems mentioned in the background technology.

[0005] According to one aspect of this application, a banquet hall simulation teaching system based on a 3D virtual hotel scene includes a 3D virtual scene construction unit, core functional modules, an interaction unit, a display unit, and a control unit. The 3D virtual scene construction unit is used to develop and construct a 3D virtual hotel teaching scene using Unreal Engine, according to the teaching requirements of universities.

The timing submodule starts a three-minute countdown after entering the fire escape virtual drill state and displays the result through a display unit. The result determination submodule, after all questions are answered, determines whether the escape was successful or unsuccessful based on whether all questions were completed within three minutes and the designated escape area was reached, and announces the result through the display unit.

[0008] Preferably, the banquet DIY module includes an arrangement resource library submodule and an arrangement switching submodule; the arrangement resource library submodule stores arrangement resources of 10 tablecloth and chair styles, 8 tableware styles, and 20 central landscape decoration styles; the arrangement switching submodule is used to receive selection instructions input by the user through the interactive unit, and retrieve the corresponding arrangement resources from the arrangement resource library submodule according to the instructions, and complete the combination and matching update in the small banquet hall specified in the 3D virtual hotel teaching scene.

[0009] Preferably, the meeting setup module includes a meeting resource library submodule and a display control submodule. The meeting resource library submodule stores setup resources for seven meeting styles: classroom style, theater style, island style, banquet style, herringbone style, square style, and U-shaped style. The display control submodule is used to receive style selection commands and show / hide commands input by the user through the interactive unit, and retrieves the corresponding setup resources from the meeting resource library submodule according to the style selection commands. The setup resources can be moved, rotated, and scaled in the 3D virtual hotel teaching scene, and multiple setup resources can be placed in a designated large banquet hall to complete the setup update in the 3D virtual hotel teaching scene. The display or hide of tables, chairs, and screens can be switched according to the show / hide commands.

[0010] Preferably, the 3D virtual teaching scene supports viewpoint rotation, forward movement, backward movement, left movement, right movement, and angle changes to achieve multiple visual 3D displays; the system is developed using a third-person perspective, and the local viewpoint can be changed to a first-person perspective as needed for the teaching content.

[0011] Preferably, the system interface of the display unit is provided with a function bar menu, which is presented in a semi-transparent state to display four modules: supervision and inspection, fire escape, banquet DIY, and meeting setup, without obscuring the 3D virtual teaching scene.

[0019] To make the content of this application easier to understand, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings.

[0020] like Figure 1As shown, a banquet hall simulation teaching system based on a 3D virtual hotel scene includes a 3D virtual scene construction unit, a core functional module, an interaction unit, a display unit, and a control unit.

[0021] The 3D virtual scene construction unit was developed using Unreal Engine. Based on the teaching requirements of universities, a 3D virtual hotel teaching scene was constructed, including elements needed for teaching such as a hotel lobby, banquet hall, hotel staff office area, dining tables, and tableware. During development, Unreal Engine's modeling tools were used to construct 3D models of each element, setting realistic materials and detailed textures, and configuring reasonable lighting effects to ensure the virtual hotel scene has excellent visual effects, providing students with a realistic virtual reality experience. Simultaneously, through the viewpoint control function, the scene's viewpoint can be rotated, moved forward, backward, left, and right, and its angle can be changed, supporting multiple visual 3D displays. The system defaults to a third-person perspective, but can switch to a first-person perspective when meeting arrangements are needed, meeting the operational needs of different teaching segments.

[0022] The core functional modules include a supervision and inspection module, a fire escape module, a banquet DIY module, and a meeting setup module. Each module is communicatively connected to the control unit, and the modules work together to achieve integrated teaching simulation functionality. The control unit triggers the corresponding core functional module to operate based on operation commands. As the core control component of the system, it coordinates data transmission and signal interaction between units to ensure stable system operation.

[0023] The interactive unit uses a keyboard and mouse, adapting to PC operating habits. Students can control the movement of the virtual character using the arrow keys or WASD keys on the keyboard, and use the mouse to rotate the view and click to select function modules, mark status items, and select answers, ensuring convenient and efficient operation.

[0024] The display unit uses a PC monitor to display the 3D virtual hotel teaching scene and related interface information during the operation of each module in real time. It clearly presents the details of the virtual scene, operation interface options and statistical results, ensuring the smooth progress of the teaching process.

[0025] The system is a Windows version, adapted for PC operation, and is used for relevant simulated teaching for college students. It eliminates the need for on-site teaching, reduces teaching costs, and improves teaching convenience.

[0066] The toilet in the bathroom is clean and odorless inside and out; the sink is free of stains inside and out; the mirror is free of water stains; and the toiletries are clean.

[0067] The inspection operation submodule allows users to interact with the system and mark various status items as compliant or non-compliant in the function bar displayed on the screen. The function bar is categorized into four areas: furniture cleanliness, countertop cleanliness, electrical lighting, and environmental cleanliness. Each category lists all corresponding specific status items, marked with either a "√" or an "×" to indicate compliance or non-compliance, facilitating clear operation for students. Students control a virtual character via keyboard to move and inspect within the 3D virtual hotel teaching scene. After observing the actual presentation of each specific status item, they complete the operation by clicking the corresponding marked option in the function bar. For example, if the items in the preparation cabinet are neatly arranged, free of residue, and the prepared tableware is in the correct quantity, a "√" is checked in the preparation cabinet status item under the furniture cleanliness category to indicate compliance; conversely, if the tablecloth has stains or uneven sagging, an "×" is marked in the tablecloth status item under the countertop cleanliness category to indicate non-compliance.

[0068] The results statistics submodule is used to statistically analyze the marking results after the user triggers the submission command through the interface control submodule, accurately reflecting the student's level of mastery of the inspection. After the student completes the marking operation and clicks the submit option, the results statistics submodule compares the student's marking results with the standard results one by one, counts the number of marking items that meet the standard results, calculates the ratio of the number of matching items to the total number of status items, and generates inspection result data.

[0069] The interface control submodule provides options for submitting and viewing results, and transmits corresponding instructions to the control unit to ensure the smooth operation of the inspection process. After students complete the marking of all status items, they click the submit option. The interface control submodule transmits the submission instruction to the control unit, which then triggers the results statistics submodule to run. After generating the inspection results data, the results statistics submodule displays it to the students through the display unit, allowing them to clearly understand their own inspection status and identify areas for weakness.

[0070] In one embodiment, the fire escape module includes a triggering submodule, a flame generation submodule, a question-and-answer interaction submodule, a timing submodule, and a result determination submodule.

[0071] The trigger submodule is equipped with a fire trigger button. Students can click the button with their mouse to trigger the system to enter the virtual fire escape drill state.

[0072] Once the system enters the fire escape virtual drill state, the timing submodule immediately starts a three-minute countdown. The countdown time is displayed in real time in a designated area of ​​the display unit to remind students of the time limit for escape.

[0073] The flame generation submodule pre-sets six fixed flame generation points within the 3D virtual hotel teaching scene, simultaneously generating flame animations. These animations utilize preset particle effects to simulate realistic flame combustion, providing clear visual identification for easy student recognition.

[0074] The question-and-answer interaction submodule pre-stores six fire safety knowledge questions. When a student controls a virtual character to enter a preset fire zone using the keyboard, the system uses a distance detection algorithm to determine the distance between the virtual character and the fire. When the distance is less than a preset threshold, the question-and-answer interaction submodule is triggered, and a question-and-answer interface pops up on the display unit, showing the question and multiple options. The student selects the corresponding answer by clicking with the mouse. The question-and-answer interaction submodule receives the answer instruction and judges the correctness of the answer. If the answer is correct, the interface displays "Congratulations! Correct answer! Please continue to find the next fire point," and the corresponding fire animation automatically disappears. If the answer is incorrect, the interface displays "Incorrect answer!", keeps the current fire animation and question-and-answer interface running, and allows the student to select an answer again until the answer is correct.

[0075] The result determination submodule monitors the completion status of the questions, the remaining countdown time, and the location of the virtual character in real time. Once all questions are answered correctly, the submodule determines whether the virtual character has reached the designated escape location and whether the countdown has not ended. If all conditions are met, the escape is considered successful; if the virtual character has not reached the designated location, the countdown has ended, or not all questions have been completed, the escape is considered a failure. The determination results are displayed as an announcement through the display unit, informing students of the drill results and helping them understand their own fire emergency response capabilities.

[0076] The specific questions related to fire safety knowledge are as follows:
