Project Case: Qunmao Interactive All‑in‑One Machines for Daily Teaching at No.9 Middle School, Jiangmen

Traditional classroom teaching relies on chalkboards, projectors and printed textbooks. Projectors struggle with bright indoor light. Projected images turn faint when sunlight falls across classroom walls. Teachers spend extra time adjusting focus and replacing old bulbs. Hand‑written chalkboards create dust. That dust affects health for both teachers and students over long class hours. Many middle schools look for better hardware to update their classroom environment. No.9 Middle School of Jiangmen City wanted to upgrade classroom teaching equipment for multiple grade‑level classrooms. The school chose Qunmao interactive all‑in‑one machines as new core teaching hardware.

These interactive units enter daily teaching work after installation and function checks. Teachers use touch screen functions to display textbook content, draw notes directly on screen, pull up courseware and play video clips during class. School staff shared real feedback after months of real‑class use. Teachers can explain textbook knowledge to students in a better and more vivid way. Students can also accept new knowledge faster and retain it to a greater extent. Education builds the foundation for science and technology, and technical products serve classroom education in return. The school expressed thanks to Shenzhen Qunmao Display Technology Co., Ltd. for supplying stable teaching display hardware.

Project Background And Actual Classroom Requirements From The School

No.9 Middle School in Jiangmen runs multiple teaching classrooms for junior‑grade and senior‑grade students. School administrators collected pain points from front‑line teachers before launching this equipment‑update project. Every requirement comes from real daily class scenarios.

Replace old‑style projector‑and‑screen setups. Get clear picture output even when natural sunlight fills the classroom space.
Support direct touch writing. Teachers should add notes, mark key knowledge points and draw diagrams right on the display surface without extra accessories.
Run mainstream teaching courseware formats. PPT files, PDF textbooks, picture resources and short teaching videos need smooth playback inside classrooms.
Simple operation for teachers. Most teachers do not receive specialized technical training. Device menus should stay easy to learn and operate.
Stable performance for heavy daily use. Each classroom device faces multiple classes every school day. It needs to stand frequent power‑on cycles and long continuous working time.
Good compatibility with existing school resources. Connect teaching computers, storage devices and campus local area network without large‑scale reconstruction of current classroom wiring.
Lower later‑stage maintenance workload for school IT staff. Parts replacement and daily troubleshooting should not create heavy work pressure for limited‑size school technical teams.

On‑Site Deployment Steps And Acceptance Work For Classroom Equipment

Classroom installation projects have special points to note. Installation work must avoid disruption to normal school teaching schedules. Our technical personnel follow a complete set of working steps for education‑customer projects.

Pre‑installation site survey. Measure wall position inside each classroom. Check wall load‑bearing capacity, confirm power socket location and network cable access points. Arrange construction time for school non‑teaching hours.
Goods receiving inspection. School staff and our technical workers check each interactive unit and accessories. Confirm no scratch, screen crack or transport damage before installation begins.
Bracket fixing and device hanging. Install wall‑mount brackets, adjust horizontal level. Hang interactive all‑in‑one machines securely onto brackets. Lock every fixed screw tightly.
Cable finishing. Arrange power cords, network lines and signal lines. Hide exposed cables as much as possible. Prevent students from touching loose wires in active classroom environments.
Hardware debugging. Power on each unit. Test touch response speed, check sound output quality, verify USB and HDMI signal access. Install commonly‑used teaching software for local teachers.
Teacher operation training. Give short on‑site training for subject teachers. Show basic writing, courseware opening, file import and common fault quick‑handling tips.
Project acceptance. School representatives test each classroom device. Confirm touch function, display picture and audio output work normally. The equipment formally goes into daily teaching use.

Main Application Modes Inside No.9 Middle School Classrooms

After deployment, interactive all‑in‑one machines serve many different teaching activities. Teachers change operation modes based on lesson plans for each class hour.

Courseware presentation. Open PPT and PDF teaching materials directly on screen. Teachers tap screen to switch pages. They add hand‑written notes over courseware content to mark examination‑focus knowledge points.
Blackboard writing replacement. Use blank white‑board software. Teachers write text, draw charts and sketch graphics right on screen. You can save all written content for later review or share files to student terminals.
