Foreword
The field of higher education is the focus of national education informationization. In recent years, it not only pays attention to the development and application of digital education resources, but also continues to develop in high-end fields such as virtual simulation. Professional display devices such as projectors are widely used, and there is still a great future. Room for improvement. Recently, we visited the University of Science and Technology of China to learn about the first-hand information of Sony projectors used here, and to explore the needs of users of higher education institutions.
User profile
The University of Science and Technology of China is a comprehensive national key university with a focus on cutting-edge science and high-tech, and a combination of characteristic management and humanities. Founded in Beijing in September 1958, the first principal was also served by Guo Moruo. In early 1970, the school moved to Hefei City, Anhui Province. Since the 1990s, it has become one of the first universities in the country to implement the “985 Project†and “211 Projectâ€, and is the only university to participate in the national knowledge innovation project.
Quiet campus, strong academic atmosphere
Application requirements
As an institution of higher learning with a strong faculty, the University of Science and Technology of China has a very complete set of teaching hardware and a high demand for product quality. In practical applications, the school's projectors equipped with classrooms mainly have the following four requirements.
The lecture hall of the University of Science and Technology of China is bright and tidy, and the students are swimming in the knowledge ocean.
First, clear picture, precise color.
High image quality is the most basic requirement of the projector for the school. It is mainly reflected in the clear display effect and accurate color. The first is to let the students in all positions in the classroom see the projected courseware content. The second is to ensure the accuracy of the projected picture. Color accuracy is especially important in data, models and other pictures.
Second, stable and durable
In the current teaching, the projector application in the classroom is very frequent. Almost every subject and every teacher fully applies a variety of teaching courseware and software to pass the knowledge to the students in a more understandable way. The school needs a stable operation of the projector to minimize accidental damage and reduce maintenance costs.
Third, unified management
The equipment of the school multimedia classroom has built a complete unified management system. The projector is an important display device. Its power status, on/off, interface control, etc. must be included in the remote management system. In addition, the related electric screen Opening and closing, PC applications, sound reinforcement equipment, recording and broadcasting equipment, etc. must be managed in a unified manner, which requires the projector to be well suited to the system settings.
Fourth, data management
For remote management, the school hopes to achieve data management and control. The various data of the projector can be displayed on the main control terminal, so that the teachers of the school audio-visual equipment can know the status of the equipment and make corresponding maintenance and replacement work. Maintenance becomes active maintenance, which is the future direction of the school for projectors and related equipment.
According to the above requirements, the University of Science and Technology of China has compared a variety of products horizontally, and finally chose Sony projectors and Sony partners-Anhui Sumai Optoelectronics Technology Co., Ltd. to provide high-quality large-screen teaching for the teachers and students of the school. Experience, make teaching more efficient, and better management.
School visit
We came to the University of Science and Technology of China to visit the application of Sony projectors in teaching, and had in-depth communication with Mr. Shao, who is in charge of the school's audio-visual equipment. Teacher Shao introduced that Sony has a deep relationship with the University of Science and Technology of China. Sony camera products have been used in schools about 30 years ago. For many years, the teachers and students of the school have recognized Sony very high. In terms of projectors, the University of Science and Technology of China has applied many brands of products. After a long period of comparison, the Sony projectors are mainly selected, and the display effect and product quality are reliable.
The general lecture classroom uses Sony VPL-CX238, 4100 stream brightness to achieve a sufficiently bright picture
You can see that there is more dust on the fuselage, and the projector needs to have excellent dustproof performance and stable operation.
Mr. Shao said that there are more than 160 multimedia classrooms in the University of Science and Technology of China, and now about 100 Sony projectors, including VPL-CX238, VPL-CX278, VPL-CX279, etc., are currently in good use. The high-brightness projection screen is very satisfying for teachers and classmates.
The lecture hall is wider and brighter, with a larger area and more students.
Sony VPL-CX278 and VPL-CX279 are used in the lecture hall, and 5200 lumens of brightness let all students see the picture.
The Sony VPL-CX279, VPL-CX278, VPL-CX238 and other feature-rich products are easy to install and have low total cost of ownership. They are designed for medium to large classrooms and conference rooms. The VPL-CX279 and VPL-CX278 have 5200 lumens of brightness, while the VPL-CX238 has 4100 lumens.
These Sony projectors feature durable 3LCD BrightEra panel technology for bright, clear images, high contrast and color stability; long lamp life and intelligent light adjustment reduce operating costs; lens shift and level for fine-tuning Features such as vertical keystone correction and advanced geometry correction are easy to adjust. In addition, it has the advantages of compact design and light weight. Sony projectors find the ideal balance between high brightness, advanced energy savings, smart connectivity and low cost of use, making them the best choice for classrooms and conference rooms.
The projector still has clear images and colors in a bright classroom environment without curtains
Shao said that he is more concerned with the performance of data information aggregation and management than the projection effect; he hopes that the projector can provide more comprehensive central control functions, present more abundant usage time, working status and other data, and enhance with other The overall management solution of the equipment meets the customized needs of the use.
The teacher is using the projector to teach
Written at the end:
Through this visit, we feel the rigor and professionalism of the University of Science and Technology of China, and scientific application and management of multimedia teaching equipment such as projectors. In terms of application, they focus on the standardization of equipment performance and classroom environment. Different models test and record relevant values ​​in actual classrooms, draw detailed charts of projector usage time and screen effects, and clarify bulb replacement and machine replacement. Related data. In addition, the school also developed environmental standards for projector applications, such as screen lights off, curtain closure, etc., for standardized application and management. The University of Science and Technology of China is very scientific and perfect in the control of projectors. Sony projectors can prove their quality in quality through rigorous selection.
