Software Architecture And Application Of Middle School Biological VR Experiment System Based On Equipment Driving

As an important educational training method to cultivate students’ practical ability,innovation ability and understanding of the scientific world middle school biological experiment is one of the main components of the middle school experimental education model.However,due to the high requirements for the experimental environment and experimental equipment in the traditional experimental teaching methods,and the boring indoctrination education,the students’ interest in the biological experiment courses is low,and the purpose of training the students by the experimental courses cannot be achieved.There is no doubt that it violates the purpose of experimental teaching,and it is not conducive to students to develop their own experimental habits.At the same time,with the rapid development and maturity of virtual reality technology in recent years,various virtual reality products are constantly being introduced and brought new experiences to modern people’s life and entertainment.Therefore,this article combines the needs of the national key special promotion and application development,finds the combination of middle school biology experiments and virtual reality technology,studies the VR experiment system based on middle school biology,and provides solutions for the above problems in middle school biology experiment teaching.The main research work of this article is summarized as follows:(1)A software architecture based on equipment driver is given.The equipment is the various experimental instruments and equipment in the experiment.It is the core part of the experiment.Through the support for the generation,function packaging and operation of the equipment,the basic content of the experiment is formed from the structure,and then the dynamic,The interactive way of manipulating the experimental equipment drives the completion of the experiment.To this end,first elaborated on the concept and method of equipment drive.Then,a detailed analysis of the number,type,experimental equipment and experimental phenomena of middle school biological experiments is given.The points based on the equipment template as the support,the experimental equipment as the core,the interactive mode as the trigger point and the experimental phenomenon as the goal are presented.Layer strategy,and then gives the equipment-driven software architecture.Finally,a software development process model based on equipment driving is given,and its development process responsibilities are elaborated in detail.(2)Designed a software framework based on equipment-driven middle school biological VR experiment system.The traditional experimental system is only a software framework for a specific experiment or a certain type of experiment,which makes the software function single,and does not have reusability and flexibility,and the middle school biological experiment has the characteristics of large number and variety.To this end,this article builds a unified underlying framework for biological experiments.Firstly,the experimental mode based on virtual reality combined with VR equipment is given,and the equipment driving is carried out through the experiment from equipment generation,interaction design and experimental phenomenon presentation.Secondly,based on the software architecture,the code framework of the equipmentdriven middle school biological VR experiment system is given,and the key implementation technologies,such as process loading based on data table configuration,event-driven messaging and feedback,and parameter-based The detailed equipment interaction will be explained in detail.(3)Implemented a software platform for middle school biological VR system based on equipment driving.The platform is for middle school teachers and students,and can provide all the experimental teaching courses of current middle school biology,including the choice of experiment library and the choice of biological experiments.For students,you can choose the test mode and practice mode.The practice mode includes the experiment report and experiment steps,so that users can carry out the experiment correctly according to the steps step by step on the basis of a certain understanding of the experiment to achieve the purpose of the exercise.The test mode provides a countdown function,experiment scoring and evaluation functions.After entering the test mode,students will conduct experiments based on their own memory.The system will record the user’s operations and score and evaluate the operations after the test.This system has been successfully used in many schools,and it is believed that it can quickly increase the interest of students in learning,and it has a good help for experimental teaching of biology courses.
