I. Introduction

Modern colleges and universities usually include various supporting functional areas such as main teaching building, office building, dormitory building, library, laboratory building, lecture hall, dining hall and sports venue; and have advanced teaching equipment and campus communication network. The requirements for the intelligence of the equipment are also getting higher and higher, especially as a large-scale campus, often because the control points are not concentrated, and because of the inconvenient management, a lot of energy is wasted, and the traditional control The above requirements are very cumbersome and it is difficult to achieve good management; therefore, an intelligent control system is needed to solve the above problems well.

Second, the project brief

Guangdong Women's Vocational and Technical College is a publicly-run full-time college. It is currently the only women's college in Guangdong Province. The college is located in Panyu District, Guangzhou City, adjacent to Lianhua Mountain Scenic Area in the east and Xijin Bridge in the west. The campus covers an area of ​​more than 200 acres and has a construction area of ​​about 120,000 square meters. It has a modern teaching building, library, training building and student apartment. , training centers and sports fields, etc., all kinds of supporting facilities are advanced. The college has modern teaching facilities. The school has 63 multimedia classrooms, e-commerce training room, international trade training room, business training room, secretarial comprehensive training room, logistics training room, computer network training room, digital art studio, and quick recording. There are a variety of professional training rooms in the school, including the accounting simulation training room, the simulated travel agency, and the property management training room. It has a complete Giga campus network and broadband dual-export (telecom network and education network). Into the Internet.

Now relying on the school's network platform, the system will carry out energy-saving renovation of 63 multimedia classrooms and 3 ladder classrooms in 3 teaching buildings. The design adopts total control control, separate control of each classroom, timing control, scene control, and remote control of air conditioning. The control objects include lighting fixtures, air conditioners, fans, and central control equipment in the classroom, and provide open interfaces for implementation with third parties. System integration; reduce waste of resources caused by managerial negligence, save energy and human resources; enhance control flexibility and reliability while fully meeting the requirements of use.
