According to data from the weekly national ICT bidding project of Hotlabs, the campus has remained high and occupied a high share, and there is a clear phenomenon that in addition to the steady growth of first- and second-tier cities, the campus informationization projects of the third- and fourth-tier cities continue. quickly growing.
First, let's take a look at the definition of a smart campus. The smart campus refers to an intelligent campus work, learning and living integration environment based on the Internet of Things. This integrated environment is based on various application service systems. Teaching, research, management and campus life are fully integrated.
In 2010, in the “12th Five-Year Plan†of informatization, Zhejiang University proposed to build an “exciting†“smart campusâ€. This blueprint depicts: ubiquitous online learning, integrated and innovative online research, transparent and efficient school governance, a rich campus culture, and a convenient campus life. So, how to achieve a high-quality smart campus? The author believes that the following three points are the most critical:
First, low-cost wireless network
Like the smart planet, the “smart campus†is inseparable from the IoT technology that is in full swing. IDC's latest data predicts that by 2020, there will be 31 billion connected devices connected to the world. By then, people will experience a continuous, ubiquitous Internet.
The primary goal of the "Smart Campus" is to connect the various objects in the campus network through the Internet of Things technology. Technically speaking, the smart earth involves the use of sensing technologies and devices such as RFID, QR code, and video surveillance.
However, as the most convenient network access method with the lowest cost, WiFi as a connection technology has been in the background of wireless fixed network convergence for a long time, and it has more and more lasting vitality. At present, wireless coverage has become a trend, and the cost of the access layer, the convenience of network quality operation and maintenance, etc. have completely surpassed the cable, coupled with the evolution of the new generation of wireless WiFi technology, the innovation of 5G architecture, in the campus network application, Promote school information education, wireless equipment, laboratory classrooms open 24 hours a day, WiFi will play an increasingly active role.
Second, we must have a unified data sharing platform and integrated information service platform
The development route from the wireless campus to the smart campus is not too complicated. WiFi can help schools to create a seamless and borderless campus Internet, create collaboration on the basis of interconnection, generate intelligent information interaction, and provide a comprehensive intelligent sensing environment and comprehensive information service platform for teachers and students to provide role-based Personalized customization service.
Some experts pointed out that the early stage of "smart campus" should be the construction and development of digital campus. The “Smart Campus†first created a unified infrastructure platform for users, wired and wireless dual network coverage; secondly, there must be a unified data sharing platform and integrated information service platform.
Third, rich application ecology
Based on the concept of future campus interconnection, we will launch a series of intelligent applications that serve students and schools. Smart locks, smart cards, student safety sensor monitoring, intelligent dormitory energy management and other applications.
"Dorm keys, drawer keys, classroom keys... a lot of strings, every time you play basketball, you will forget to bring them, but since I know the Internet of Things, I don't have to worry about being "rejected" without a key. The mobile phone can also Open the door." Xiao Chen, a college student in charge of engineering, said with relish. After all, he took out his mobile phone from his pocket and slammed it in front of the access control card reader. He slammed the door and the dormitory door opened. The school also manages the cardholder's authority by means of the access control subsystem, which greatly improves the security of identity recognition.
