▲ 3D simulation teaching software and 3D virtual simulation platform that are compatible with this process. 3D simulation software has administrator end, teacher end, and student end, which can realize networked teaching experiments; ▲① LAN version installed on the school's internal servers; ② Network version that can be used online without geographical restrictions; ③ Students can learn device operations through this platform on both their mobile and computer devices; ④ ▲ The software provides a 360 ° free roaming perspective for characters to observe various angles of the experiment, including scene and background music, voice broadcasting, and scene switching functions; ⑤ Experimental introduction function that includes experimental principles, experimental objectives, and experimental steps; ⑥ In this interface, specific operation instructions can be seen. ⑦ Voice broadcasting and text assisted recognition equipment components and purposes; ⑧ Simulate experimental functions according to the operating steps of the experiment; ⑨ The software platform can record and save the real-time operation of the software by students; ⑩ Students take the exam according to the experimental steps, and the system can score on site and upload it to the teacher's end.

▲ (1) 3D Virtual Simulation Platform: After logging in to the administrator and teacher accounts, you can see 23 functional menus including personal information, school management, college management, department management, grade management, class management, device list, exam management, test paper management, student test paper, sign in management, new job management, unapproved homework, subject management, homework grades, exam scores, wrong papers, unapproved homework, notification announcements, homework, score queries, online users, and system settings. These menus include adding department names, responsible persons, contact phone numbers, email information, administrator user nicknames, email addresses, user names, positions, school names, self setting passwords, searching and querying members, uploading files, file types, majors, subjects, and school IDs. The, You can upload teaching materials and exam questions in the form of documents on the software platform. You can set Single choice question questions, multiple choice questions, judgment questions, fill in the blank questions, contents, subjects, and add answers. ▲ You can query students' previous exam scores and use 3D simulation software; Students can freely learn the use and operation of experimental equipment 3D simulation teaching software through this platform on their mobile phones and computers, complete theoretical knowledge learning, and the system can immediately automatically grade and generate exam scores, which are uploaded to the teacher's end in real time.

▲ (2) Provide high-definition screenshots of each function of the above software in the bidding documents, as well as QR code format ▲ software recording, so that the judges can clearly see the content of each function in the above parameters (static images are considered invalid and provided), verify the simulation platform function and the 3D simulation function of the experimental equipment. After winning the bid, the purchaser has the right to request the winning bidder to provide a software installation package for parameter demonstration. If there are false responses, refusal to demonstrate, etc., the purchaser has the right to terminate the contract and the winning bidder shall bear all consequences.
