Smart campus can not be separated from intelligent lighting

When night falls, the street lights in the campus will automatically glow, shining through mottled light and shadows through the gaps in the leaves. The students step on broken pieces of light and chat with the scandals around them, praising the story of the city. .... Each street light illuminates the campus life of the student era. However, in the face of this special group of students, the street lights on campus are also quietly changing.

"Not only should we demonstrate functionality, we must also reflect the artistry; we must not only save energy, but also ensure proper lighting to ensure the safety of students at night." With the development of the Internet age and the rise of smart technology, schools have put forward higher-level requirements for campus lights. “Intelligent street lights” have become new terms for major schools in the new era. In the expansion of the school and the construction of the new campus, it began to pay more attention to the energy-saving and scientific management of lighting. Intelligent lighting highlights the unparalleled advantages.

The "big problems" in micro cities

Compared to the city, the school is like a miniature city. It has different functional areas such as teaching area, dormitory area, and sports area. The roads are also complicated, with main roads, secondary roads and various trails that run through the campus. According to the streetlight's functionality, campus streetlights can be divided into two parts: lighting streetlights and landscape streetlights. Among them, the traffic flow of main roads is relatively concentrated, and there are fewer pedestrians at minor roads and tree-lined roads at night. Therefore, each road needs different light, which poses a problem for the control of street lighting.

According to the survey, after entering the early hours of the day, many schools have almost no pedestrian traffic on campus. However, the street lights on campus are bright all night. This is called the "night light." Moreover, most colleges and universities use traditional lighting centralized control methods: manual control, time control, or light control. Manual control of labor intensity, opening or closing is not timely, time control and light control are vulnerable to external environmental interference, or other factors, resulting in a lot of waste of resources.

The appearance of the intelligent lighting control system can solve the above problems perfectly. The lighting system can automatically realize the switch and dimming function according to the specific environment and conditions such as the student's activity pattern and the flow of people. With automatic control as the mainstay and manual control as the supplement, the number of management personnel is greatly reduced. Managers can monitor and adjust campus street lights at any time, thus protecting the lighting needs without causing unnecessary waste and protecting the school’s Normal teaching and life order.

The "nervous system" on campus

Recently, a university in Harbin successfully completed the transformation of the road lighting control system in the school district, and joined the intelligent “Nerve System”—Intelligent Lighting Single Lamp Control System—to make the street lights “think”. The entire system is based on advanced wireless communication technology and uses a unified cloud platform for efficient management. It enables remote switching, dimming, monitoring, and loop control of single lamps without changing the structure of the lamps or wiring. It supports latitude and longitude timing. Switch, light and scene settings, etc., to achieve energy-saving and environmental protection, intelligent control.

“The intelligent management of street lamps requires three magic weapons: single lamp controllers, centralized controllers, and street lamp monitoring software.” “The single lamp controller is the “eyes” of street lamps, combined with the ZigBee communication technology The management personnel intelligently control and dim the street lights in the campus on the monitoring software, and can also monitor the voltage, current, and power of each lamp. The centralized manager is the "central nervous system" of the entire system and manages single-lamp controllers for the entire area to achieve remote control.

The street lamp manager of the university campus said, “With the change of the season, the time of darkness and dawn was changing, it was difficult to achieve scientific control. Sometimes it was dark, the lights were not bright, and sometimes it was dawn and the lights did not go out. Need to invest a lot of manpower to operate.After the transformation, according to the local latitude and longitude, seasonal changes and daily sunrise, sunset time, automatically adjust the switch lamp time.When the flow of people is large, the street lamp automatically brightens, in the flow of people In the low case, the brightness can be automatically reduced; in the middle of the night, the control of the street lights is a bright one. According to estimates, more than 30% of the energy can be saved each year, and the effect is still quite satisfactory.

In the past 100 years, education has been the foundation. Since the beginning of the year, the campus informationization has received great attention and attention from all walks of life. Under the background of rising emerging technologies such as cloud computing, the Internet of Things, and mobile Internet, the construction of “smart campuses” has become a necessary way to achieve new developments in education. Intelligent lighting control system is only one of the tools for smart campus management. More intelligent applications need continuous trial and exploration to enjoy the excellent results that science and technology bring to education.
